Mathematical prototype: Its mathematical prototype is the simple, classic, vivid, and widely used in social production practice, elementary school mathematics "water inflow/outflow of the pool". My theory rebuilt the theoretical foundation of the IT industry, It makes the computer theory system fully & perfectly related to mathematics in a simple and unified way: from hardware integrated circuits and computer architecture, to software programming methodology, architecture, programming language and so on. It solve the most fundamental and core major problems in the IT industry: The foundation and core of the IT theory lack mathematical support.

After I created the "Warehouse/Workshop Model", I became enlightened and achieved what Confucius said, "My Tao is consistent." That is: My doctrine can be connected by a fundamental principle (or ideology). Throughout human history:
- There are very few people who can use a fundamental principle (or ideology) to penetrate an industry theoretical system.
- Fewer people can use a fundamental principle (or ideology) to penetrate multiple industry theoretical systems.
- It is even rarer to be able to prove this fundamental principle (or ideology) with a mathematical model.
- A person who enables elementary school children to understand this fundamental principle (or ideology). Only me. Therefore, my theory is the closest to the "Tao" theory.

The simplest, most scientific, most vivid, and most perfect IT theoretical system diagram. Success Story
Judging from the reactions on professional forums, I know a lot of people hate this picture and the self-aggrandizing language. but it is also my claim or argument, I don't mind being downvoted, I just prefer that they prove my argument wrong at the same time. If they can't prove me wrong, They should reflect:
-
Why do they hate a great truth so much?
-
Why would they stand against a great truth?
-
What role do they play in this act?
I have always believed that such irrational and unscientific attitudes and behaviors can be ignored.

Using the input and output characteristics of pure functions, pure functions are used as pipelines. Dataflow is formed by a series of pure functions in series. A dataflow code block as a function, equivalent to an integrated circuit element (or board)。 A complete integrated system is formed by serial or parallel dataflow.
Can also be said, Data and logic are strictly separated, Element level separation of data and logic, data stream processing.

The design philosophy of industrial pipeline and pure function pipeline data flow is the same. In essence, they are: "Towards the goal, Step by step, every step moves forward to the final goal until the final goal is reached." Therefore, its success is inevitable, not surprising, the process is a simple repetition. After using this method proficiently, it is a simple and repeated boring technique. This is the simplicity and repetition pursued by large industrial production lines.
Pipeline Component (forward flow)
Pipe functions are pure functions.
A ->>
block function is equivalent to
an integrated circuit component (or board).
-
Side effects
- Most of the functions in a
->>
block are pure functions. - A data flow has at most two functions with side effects and only at the beginning and the end.
- In the
warehouse/workshop model
, the side effects are handled by the dedicated IO department (purchasing department, sales department). Therefore, all workshops (pipes) are pure functions, only interact with the warehouse and are scheduled by the warehouse.
- Most of the functions in a
-
Parameter
- Check and standardize the data at the entrance, and then run at the extreme speed, which is simple, smooth, stable and efficient.
- In Clojure language, it is recommended to design the
function as a hash-map type single parameter function
as much as possible.
- Like most functions of the R language, many named parameters with default values can be designed, which has strong scalability.
- Clojure has many core functions for operating hash-map, which is very convenient.
- It is not necessary to write parentheses when using
the
->>
macro. In this way, Clojure becomes the programming language with the fewest parentheses :-) - Parameter formation, verification, transformation and function call integration, one-stop data flow processing.
- Clojure is easy to deconstruct, and it is as convenient to use as multi-parameter functions.

The true sign of intelligence is not knowledge but imagination (analogy).
---- Albert Einstein
Analogy is an application of algebraic thinking. An analogy may not be established in the real world, but it must be established in the virtual software world, it is very easy to map an old model to a new model and upgrade according to the standard specifications of the new model. In management, it is called "merger by absorption".
This is a typical application of the philosophy of the Tao
and the Grand Unified Theory

data-flow is current-flow, function is chip, thread macro (->>, -> etc.) is a wire, and the entire system is an integrated circuit that is energized.
-
Data (flow) is raw material (flow), pure function is machine, the thread macro (->>, -> etc.) is the conveyor belt, and the entire system is a large industrial pipeline.
-
Communication modes, data signals and control signals (annotations or metadata) flow through the pipeline.
-
The compiler is essentially a data transformation, starting with the source code, through a series of pure function pipeline transformation optimization, up to the machine code. It's very easy to insert enhanced optimizations or features, and parallel compilation is also very simple.

Warehouse
-
It is a special pipeline, a container for all resources (status, data, and functions are also data). It has two special side-effect pipelines (I/O) that are connected to the outside world.
2022-03-12 Note: My theory is built under the architecture of Principle-based Warehouse/Workshop Model, The separation of data and logic is the basis for implementation, but It does not recommend "Defer Side Effects Until the Last Possible Step", it just treats side effects as a special professional workshop according to the principle of Division of tasks, and is scheduled by the scheduler like ordinary workshops. It simply divides tasks at resource contention points according to their professions and the Gantt chart algorithm, and allows professional people (departments, workshops) to do professional things and unify the scheduling in an optimal way, not delaying but optimal. A discussion in r/programming
-
It has a scheduler, the warehouse scheduler and the workshop are 1: n relationship, the warehouse scheduler uses Gantt chart algorithm to dynamically plan and schedule the workshop to complete tasks for global optimization.
- Standard Gantt chart algorithm dynamic programming scheduling: The task designer is an internal user who can correctly estimate task time, dependencies between tasks, and divide tasks correctly. This is the optimal scheduling algorithm.
- If the task designer is an external user,
such as the task designer of a cloud service provider,
it is difficult to guarantee that they can do this.
- Preemptive multitasking scheduling: Traditional computer science uses preemptive multitasking to schedule tasks, forcing division of tasks in resource competition, preventing inappropriate or long-term computing tasks from occupying resources and causing other services to wait for a long time. both service providers and external users cannot control and optimize tasks well, and lack certainty and predictability of task execution (path, timing, and results). So it's not a high-performance method, just a simple and crude method. It schedules tasks by priority and time slice, which is usually short (5ms-800ms on Linux), resulting in a lot of unnecessary task switching overhead. Preemption (computing)- Wikipedia
- Contract Scheduling (Mixed Mode Scheduling, Scheduling by Resource)(2022-02-28): If the manufacturing industry method is adopted, Cloud service providers customize resources into data flow and computing flow services in standard units of different levels and types. various types of standardized products (resource use rights) lists are provided by service providers, because tasks are difficult to unify and standardize, so it is difficult to measure and schedule, while resources can be simplified, Unification and standardization, standardized resources and data flow units can be used as calculation units for quantitative analysis according to the formula of mathematical prototypes, so it is natural to change scheduling tasks to scheduling resources. This idea is consistent with the idea of data flow. the external user program issues the purchase product (resource use right) order according to the needs of the task plan during the running period, obtains the resource use right to run the task after the transaction is successful, and finally returns the result to the external user. This kind of active control is handed over to the external user, both service providers and external users can better control and optimize tasks, and help to enhance the certainty and predictability of task execution (path, timing, and results). Its optimization effect is close to the standard standard Gantt chart algorithm dynamic programming scheduling, far exceeding preemptive multitasking scheduling. Cloud service providers and users strictly trade according to the contract, which is also a more accurate measurement, more guaranteed service quality, and more rigorous business transaction method.
-
It may not have an ordinary workshop, at this time it is just a data center (warehousing industry).
-
It can have no container, at this time it is just a dispatch center (Virtual Unified Warehouse, integration layer or platform, the parent company of the enterprise group).
- Its workshops are all lower-level warehouses/workshop models (subsidiaries). It does not directly schedule the resources of the sub-models (subsidiaries), but indirectly schedule them through the schedulers of the sub-models (subsidiaries), simplifying the scheduling system. Ensure the independence of the sub-model (subsidiary). Enhance the certainty and predictability of the execution path, time, and results.
- Conducive to promoting the adjustment of the architecture.
- Conducive to the formation of group advantages and comprehensive functions, and enhance the integration of the system.
- Conducive to professional collaboration.
- Conducive to achieving economies of scale.
- Conducive to improving the level of dispatch.
- Conducive to improving the efficiency of resource utilization and promoting the optimal allocation of resources.
- The standard Warehouse/Workshop Model is of course the most efficient,
but the fractal system is necessary in the following situations.
It is not the optimal solution for the ideal world,
but it is the optimal solution for the real world.
There are many things in this world that we cannot fully control
and pursue the maximization of our interests. We can only cooperate and win-win.
- When the scale is too large to control, This situation may only exist in the hardware system. In the software system, this situation generally does not happen, because it is just a bunch of simple workshop functions surrounding a DB, which is very simple.

Workshop
It is an independent unit that performs tasks within the system. each workshop is an independent pipeline with a single function. they are small, simple and clear.
- It is a larger execution unit than a data pipeline and consists of a series of data pipelines.
- There is no interaction between the workshops, and each workshop is only uniformly scheduled by the warehouse.
- It is the atomic unit when dividing independent tasks, corresponding to a bar of the Gantt chart.
- It can have no warehouse, at this time it is just a microservice (service industry).
-
Warehouse/Workshop Model
-
From the perspective of stati, it is a star.
-
From the perspective of dynamic runtime, it is a dynamic tree Gantt chart, like a rushing river system.
-
When the scheduler calls the workshop, a data (raw material) is assigned to a workshop.
-
when the data (raw material) enters the production (change, computing) process as consumables, it is exclusive to the workshop. The scheduler will no longer assign it to other workshops, because it makes no sense to refer to dirty data that is in the production (change, computing) process.
-
Workshop as a pure function, It no longer gets data from the outside world, except for the data assigned to it by the scheduler at the beginning of the task.
-
-
If you understand that software is a factory that produces data, then you can understand the warehouse/workshop model, understand the separation of production lines (pure functions, pipelines, workshop) and production materials (data), and continuous production on the production line forms a data flow.
The basic principle of the system is similar to an in-memory database system.
like the in-memory database, all tasks of the system are completed by scheduling stored procedure (workshop),
and all side effects (similar to persistence, distributed, etc.) are completed by the in-memory database.
-
Everything is a pipeline: the perfect way to achieve the simplicity and unity of the software ecosystem.
-
Pipeline combination: The cascade of

- Parallel independent

formwarehouse/workshop model pipelines (data factory)
throughwarehouse
collaboration (scheduling). - The
workshop pipeline
can be used as apackaged integrated pipeline (integrated chip)
to independently provide services to the outside world, which is a microservice or service industry. - All workshops are independent black boxes (pure function), it does not need to know where the data comes from and where it is going, It only needs to complete its functions according to the data assigned to it by the warehouse.
- They are all independent and can be safely paralleled.
- Parallel independent
-
Warehouse
-
It can provide services as an independent entity, which is a warehousing industry or database server.
-
The warehouse uses the best algorithm of the Gantt chart to arrange the workshop to complete tasks according to the status changes (such as orders, etc.).
-
The warehouse saves the global state. If the system fails, it is easy to find the fault by analyzing the warehouse snapshot.
-
All side effects are done by the warehouse agent. such as get data from other warehouses as needed (distributed DB, disk, etc), persist data, etc. side effects can be regarded as a special workshop, such as purchasing department, sales department, etc.
-
-
Warehouse/Workshop Model combination
- Various independent
Warehouse/Workshop Model pipelines (data factory)
can be used as apackaged integrated pipeline (data factory, integrated chip)
and then combined into a largerWarehouse/Workshop Model pipeline (data factory)
, - This is the method of interconnection, collaboration, and integration of different developers and different software products, and is also the basis for software development and standardization of large-scale industrial production.
- This is the corporate group or the entire industrial ecosystem.
- Various independent
-
Finally, the pipeline is like a cell, combined into a pipeline software ecosystem that meets the requirements of the modern industrial ecosystem. This is the perfect combination of simplicity and unity.
-
Contrast with
Everything is an object
- The object is a furry ball, and there is a chaotic P2P (peer to peer) network between the objects. It is a complex unorganized system.
- The pipeline is a one-way ray, and it's the simplest that data standardization and combination. It is a simple, reliable, orderly, observable and verifiable system.
-
-
Because software is a factory that produces data, so modern industrial systems are suitable for software systems.
-
Warehouse(database, pool)/Workshop(pipeline) Model is simple and practical model, and the large industrial assembly line is the mainstream production technology in the world.
-
The best task planning tool is the Gantt chart, and the best implementation method is the warehouse/workshop model implemented by the factory.
-
I think that if the data flow theory only has rivers (input workshops), no clouds and rain (output workshops), and no oceans and lakes (warehouses), then it is not a closed-loop system, so it is theoretically incomplete.
- Divide tasks by Gantt chart.
- A type of task is only responsible for the corresponding type of workshop.
- Data management is handled by the warehouse.
- Task scheduling is in charge of
the scheduling function of warehouse
.
-
Single leader
- Except for the root warehouse, all components (workshops, warehouses, models)
have and only one leader (
the scheduling function of warehouse
). - A single leader helps to enhance the certainty and predictability of task execution (paths, times and result).
- Multiple leaders will cause any leader to lose control of the execution of the task,
produce unpredictable results, and destroy the results of using
dynamic programming
to achieve global optimization.
- Except for the root warehouse, all components (workshops, warehouses, models)
have and only one leader (
-
Unified scheduling
- Unified scheduling by
the scheduling function of warehouse
. - The scheduling function dynamically plans
the order of completion of tasks according to
the Gantt chart algorithm, and calls the workshop
to complete the assigned tasks.
- Standard Gantt chart algorithm dynamic programming scheduling: The task designer is an internal user who can correctly estimate task time, dependencies between tasks, and divide tasks correctly. This is the optimal scheduling algorithm.
- If the task designer is an external user,
such as the task designer of a cloud service provider,
it is difficult to guarantee that they can do this.
- Preemptive multitasking scheduling: Traditional computer science uses preemptive multitasking to schedule tasks, forcing division of tasks in resource competition, preventing inappropriate or long-term computing tasks from occupying resources and causing other services to wait for a long time. both service providers and external users cannot control and optimize tasks well, and lack certainty and predictability of task execution (path, timing, and results). So it's not a high-performance method, just a simple and crude method. It schedules tasks by priority and time slice, which is usually short (5ms-800ms on Linux), resulting in a lot of unnecessary task switching overhead. Preemption (computing)- Wikipedia
- Contract Scheduling (Mixed Mode Scheduling, Scheduling by Resource)(2022-02-28): If the manufacturing industry method is adopted, Cloud service providers customize resources into data flow and computing flow services in standard units of different levels and types. various types of standardized products (resource use rights) lists are provided by service providers, because tasks are difficult to unify and standardize, so it is difficult to measure and schedule, while resources can be simplified, Unification and standardization, standardized resources and data flow units can be used as calculation units for quantitative analysis according to the formula of mathematical prototypes, so it is natural to change scheduling tasks to scheduling resources. This idea is consistent with the idea of data flow. the external user program issues the purchase product (resource use right) order according to the needs of the task plan during the running period, obtains the resource use right to run the task after the transaction is successful, and finally returns the result to the external user. This kind of active control is handed over to the external user, both service providers and external users can better control and optimize tasks, and help to enhance the certainty and predictability of task execution (path, timing, and results). Its optimization effect is close to the standard standard Gantt chart algorithm dynamic programming scheduling, far exceeding preemptive multitasking scheduling. Cloud service providers and users strictly trade according to the contract, which is also a more accurate measurement, more guaranteed service quality, and more rigorous business transaction method.
- No resource competition and transaction (version) conflicts
- This approach is the easiest to optimize the overall efficiency of the system.
- The global unified scheduling system is the most efficient, which is a common sense.
- To complete a task (product), it is necessary to combine various workshop production (heterogeneous parallelism), The warehouse scheduler uses operations research to achieve the optimal balance of supply (input), production (computing), sales (output), and storage (warehouse), achieve minimum cost and maximum efficiency.

Empowerment
-
I think that full empowerment is to achieve the effect of the missile's "Fire-and-Forget" technology. "Fire-and-Forget" is a guidance bullet with independent guidance capability. It does not need external support, it will automatically track and strike the target, and do not need to control after launching. The utility model has the advantages of improving the use efficiency between the missile and the launcher, and reducing the missile's dependence on other systems to provide its own updated information, so that the launcher can attack the largest number of targets in the shortest time and improve the survival of the launcher. The development direction of guidance technology in the future is precisely the "Fire-and-Forget" precision guidance technology.
-
If the workshop cannot achieve "Fire-and-Forget" and still needs to participate in management and control with the manager (scheduling function), then the task division is unreasonable, and the task should be divided at the intervention point of the manager (scheduling function).
-
Advantage
- Reduce the complexity of the system (overall and components)
- Enhance the independence of each component, perform its own duties, don't interfere with each other, and enhance the simplicity and parallelism of the components.
- Make the task division reach the maximum granularity under the premise of ensuring independence, and ensure the continuity and efficiency of task execution.
- Communication, coordination and conflict management have great damage to performance, and it can reduce these damages to a minimum through division of tasks, unified scheduling and empowerment ("Fire-and-Forget").
- Improve the efficiency of parallel, concurrency, distributed, asynchronous, etc.
- Unified the architecture of parallel, concurrent, distributed, asynchronous, etc.
- Enhance the optimization effect of global scheduling
- Unified form of Manager (scheduling function) manages and controls the workshop.
- Achieve the simplicity and unity of the system.

-
Management by Objective
-
Empowerment isn't laissez-faire, it is mainly to carry out strict and standardized total quality management of work results.
-
As long as the accuracy of the data in the warehouse is ensured, the accuracy of the input and output data of the workshop can be guaranteed, and the accuracy of the system can be guaranteed.
-
The acceptance function of warehouse is responsible for management by objective.
-
- All components (workshops, warehouses, models) are pipelines.
- From the component point of view, it is a pure function pipeline fractal system.
- From the perspective of system architecture, it is a warehouse/workshop model fractal system.
- Realize the perfect combination of system simplicity and unity. It's the ultimate simplicity and unity when all elements (including architecture) have the same form.
- Because the system is a fractal system, the growth of the system will not increase the complexity of the system, and it can still remain simple and unified.
- Similar
- A complex life form is composed of countless simplest cells.
- A complex CPU is composed of hundreds of millions of simplest transistors.
Workshops are decentralized and independent, but each workshop is connected with warehouse to form a system.
-
Concentration: Data Concentration, Global unified scheduling of tasks.
- Data is centrally managed by the warehouse. Data verification and constraints are very convenient, which helps maintain the integrity and correctness of the data
- It completely displays the standard specifications of the data and helps to understand the data correctly and comprehensively.
- It is conducive to obtaining comprehensive information and optimizing the system from a global perspective as the basis for unified scheduling.
- When debugging, you can easily save the global information of the warehouse when it is running, and analyze the cause of the failure.
- The maintenance cost is the smallest and the management is the simplest.
- Global unified scheduling of tasks: The global unified scheduling system is the most efficient, which is a common sense.
-
decentralization: independent and parallel execution units (workshops)
- Data processing is independently produced by each workshop, there is no interaction between each workshop, and each workshop is only responsible for the warehouse.
- Scheduling workshops to complete system tasks with the most optimized algorithm,
which is the responsibility of
the scheduling function of warehouse
.
- In a warehouse/workshop model,
all workshops are managed by one
scheduling function of warehouse
. - Each warehouse/workshop model can be used as
a workshop component (integrated pipeline, like an integrated chip)
and managed by
the scheduling function of upper-level warehouse
.
-
Each workshop should have definite standard specifications for input data (parameters) and output data (return values).
-
Each
warehouse/workshop model (warehouse)
has a definite standard specification for input/output data to the external environment. -
Architecture's definiteness
- Based on mathematical models, operations research, management science
- With 10 principles, 5 aesthetics, and 5 basic components
- The architecture can be visualized with a simple star chart and Gantt chart
- In the same case, the architecture designed by different people will be consistent and clear. The pros and cons of different people's design schemes can be accurately judged by mathematical models and operations research. For this situation, it is generally called science.
-
Each workshop transforms the initial state to the target state step by step through a series of pipelines (pure functions), and finally returns to the warehouse.
-
The tasks of the entire system are dynamically planned by the scheduling function according to the Gantt chart algorithm to dynamically plan the execution order of the tasks, and the workshop is called to complete the assigned tasks.
-
It's like a rushing river system diagram that the sequential rendering of the entire continuously running system. It is also a variant of the Gantt chart. This is Boeing's aircraft pulsating assembly line, which is essentially an optimized assembly line.
- The main river is the main production line
- Every branch river is a large part production line
- If we divide the river (production line, workshop) into several important stages, every time a stage of the river (production line, workshop) is completed, one step closer to the final product. Finally, until the end, the final product is obtained.
- Modular design and manufacturing. The point where the branching river merges into the upper-level river is the point where large parts are assembled to the upper-level product.
- The output data of each workshop is checked and accepted by the warehouse's acceptance function, so as to ensure the correctness and standard of the input data of each workshop and improve the efficiency and quality of the system.
- Dynamic tree Gantt chart: Taking the main task (main river, main production and assembly line) as the time axis, the end point of the branch task is connected to the meeting point with the upper-level task, then the entire task flow chart (a rushing river system diagram) forms a dynamic tree Gantt chart.
- Complex data structure: It is a very simple that data structure is manipulated by the method of manufacturing an airplane. Divide the data, manipulate the data from bottom to top, combine layer by layer, and finally complete the task. After all, there is no data structure more complicated than airplanes in the IT field.
-
The out-of-order execution technology of modern CPUs is a mistake
Out-of-order execution is a product of wrong programming methodology, wrong computer architecture and weak compiler conditions.
In the "warehouse/workshop model", the workshop is an orderly and high-speed ray(pipeline). The warehouse scheduling function performs dynamic planning and unified scheduling for all workshops and resources, without conflict and competition, and runs in the optimal order and efficiency.
-
All data are produced and organized according to standard specifications.
-
Refer to the standard system of the manufacturing industry, and take the data interface standard system as the type system. The acceptance check is performed and centrally managed by the warehouse, and the system logic will be simple, short and reliable.
-
It can reduce unnecessary data verification, cleaning, conversion, and abnormal processing during execution, and keep the logic of the workshop simple and efficient.
-
By learning the methods of standardized production in the manufacturing industry, the software is regarded as a factory for producing data. With data as the center, before development, the standard specifications of data (products, parts, raw materials) are fully and accurately defined, and then the production data is standardized according to the data standards. This method is simple, reliable, and reusable. Bugs in the software industry emerge endlessly. In the final analysis, they are not standardized enough. Just like the manufacturing industry, even the smallest screws have detailed standard specifications and quality control methods in terms of size, shape, material, strength, hardness, corrosion resistance, and craftsmanship. This kind of production method is The ultimate way to eliminate bugs. The gap between the two industries is the gap between the era of handicraft industry and the era of modern standardization.
-
Exceptions refer to new situations and problems that are difficult for each workshop to adjust by itself or not included in the original design.
- There are no exceptional situations and problems in the normal standardized production workshop.
- The special "side effect workshop" interacting with the external environment is responsible for input and output, which may cause abnormalities. The workshop should try its best to resolve the exceptions that it can solve. Only exceptions that the workshop cannot handle are submitted to the direct manager (scheduling function). The workshop should provide detailed exception information and possible solutions when submitting the exception.
- The scheduling function may need to coordinate exceptions between workshops, similar to transaction management and deadlock handling in RMDB.
-
The manager (scheduling function) should avoid dealing with specific tasks, which is the responsibility of the workshop.
-
Exceptions are handled by the management (scheduling function) dispatched (or established) "specialized workshop for handling exceptions".
- Special workshop for handling exceptions: similar to the transaction manager and deadlock handler in RMDB.

Its mathematical prototype is the simple, classic, vivid, and widely used in social production practice, elementary school mathematics "water inflow/outflow of the pool".
-
When we increase the number of water pipes, the combination of different types of liquids, the time and speed of input and output, and other factors in this mathematical problem. Taking the timeline of the main process as the main axis, dynamic rendering of the system will form a warehouse/workshop model in the form of a dynamic tree Gantt chart.
-
When we continue to add more "water inflow/outflow of the pool" systems, it will constitute a warehouse/workshop model fractal system. For a certain "water inflow/outflow of the pool" system, other systems can be abstracted as pipes.
It should be the IT architecture with the simplest and most vivid mathematical prototype.
My theory rebuilt the theoretical foundation of the IT industry, It makes the computer theory system fully & perfectly related to mathematics in a simple and unified way: from hardware integrated circuits and computer architecture, to software programming methodology, architecture, programming language and so on. It solve the most fundamental and core major problems in the IT industry: The foundation and core of the theory lack mathematical support.
s = vt
s: Data flow (inflow/outflow volume), computing flow (computing amount), etc.
v: velocity
t: time
Every warehouse or workshop is a pipeline (functional pipelined data flow),
Every pipeline (functional pipelined data flow) is an s=vt equation.
Therefore, every warehouse or workshop is an s=vt equation.
Every system is a fractal system composed of many pipelines (warehouses or workshops),
Every pipeline is an s=vt equation,
Therefore, every system is a fractal system composed of many s=vt equations.
Every system is a warehouse/workshop model,
Every warehouse/workshop model is a pool/pipeline system,
Every pool/pipeline system can be abstracted as a pipeline,
Every pipeline is an s=vt equation,
Therefore, every system is an s=vt equation.
Every system dynamic runtime can be rendered as a dynamic tree Gantt chart,
Every dynamic tree Gantt chart is a pool/pipeline fractal system,
Therefore, every system dynamic runtime is a fractal system of s=vt equations.
Note:
- example: inflow/outflow volume can be composed of bits. The warehouse stores everything.
warehouse: pool, buffering between inflow and outflow, the target of the inflow, the source of the outflow. with a globally optimized scheduler for the combined workshops. To complete a task (product), it is necessary to combine various workshop production (heterogeneous parallel computing forms a parallel dataflow), The warehouse scheduler uses operations research to achieve the optimal balance of supply (input), production (various workshop, heterogeneous parallel computing forms a parallel dataflow), sales (output), and storage (warehouse), Make full use of all available resources, reduce resource competition, waiting, and transaction conflicts, achieve minimum cost and maximum efficiency.
result = scheduler_operations_research_strategy(warehouse, various_workshop_inflow_outflow)
This function decomposes the task into a dynamic tree Gantt chart (s=vt equation fractal system)
according to the resource conditions, and then heterogeneous parallel computing forms a parallel dataflow,
which is like a rushing river system. until the end.

Common sense in scientific research: repeatability and verifiability
There is no definite, operational theoretical basis for design and evaluation, design is very arbitrary, and good examples of OO & FP & hardware architectures are rare.
Because the same case, different people design OO & FP & hardware architecture varies greatly, and it is difficult to evaluate the advantages and disadvantages. So they belong to what
Pauli
said"Not Even Wrong"
In short, they are not repeatable, not verifiable, and not scientific at all. They are pseudoscience.

"Not even wrong" is a phrase often used to describe pseudoscience or bad science. It describes an argument or explanation that purports to be scientific but uses faulty reasoning or speculative premises, which can be neither affirmed nor denied and thus cannot be discussed rigorously and scientifically.
For a meaningful discussion on whether a certain statement is true or false, the statement must satisfy the criterion of falsifiability, the inherent possibility for the statement to be tested and found false. In this sense, the phrase "not even wrong" is synonymous with "unfalsifiable".
History of the expression
The phrase is generally attributed to the theoretical physicist Wolfgang Pauli, who was known for his colorful objections to incorrect or careless thinking. Rudolf Peierls documents an instance in which "a friend showed Pauli the paper of a young physicist which he suspected was not of great value but on which he wanted Pauli's views. Pauli remarked sadly, 'It is not even wrong'." This is also often quoted as "That is not only not right; it is not even wrong", or in Pauli's native German, "Das ist nicht nur nicht richtig; es ist nicht einmal falsch!" Peierls remarks that quite a few apocryphal stories of this kind have been circulated and mentions that he listed only the ones personally vouched for by him. He also quotes another example when Pauli replied to Lev Landau, "What you said was so confused that one could not tell whether it was nonsense or not."
Columbia physicist Peter Woit used the phrase in the title of his book Not Even Wrong: The Failure of String Theory and the Search For Unity in Physical Law. Woit also writes a blog of that name.

Not Even Wrong, BY JASON LISLE, PH.D. * | TUESDAY, DECEMBER 30, 2014
Physicist Wolfgang Pauli was once asked to review a technical paper and assess its accuracy. The content was so garbled, however, that Pauli is said to have remarked that not only was the paper not right, it was “not even wrong.” He meant the paper was so poorly written, so muddled in its reasoning, that it was impossible to evaluate in any fashion. It was even worse than wrong—it was incoherent. The author would have to substantially improve the paper in order for it to even be assessed as wrong.
Science is largely a literary endeavor. It advances only when scientists are able to communicate their discoveries to other scientists for independent evaluation and confirmation. A hypothesis that is not clearly stated cannot be tested. Only when experimental methods are carefully articulated can they be critiqued or validated. Therefore, scientists must be able to cogently articulate their hypotheses, observations, and methods. They must carefully define important terms and use them in a consistent way. Anything less is confusing at best and “not even wrong” at worst.

In the same case, the architectures designed by different people will be consistent and clear, and the superiority of different people's design solutions can be accurately judged by mathematical models and operations research, which is in line with the scientific principle of repeatable and verifiable certainty, so we call it science. The best people can effectively prove the superiority of their solutions by mathematical methods, so this method is the choice of the best people.

In my mathematical and principle-based "warehouse/shop floor model" theory, uncertainty exists in a deterministic principle-based framework and mathematical model. Uncertainty is controllable, and when an uncertain event occurs, the scheduler can immediately optimize it by dynamic planning and incorporate it into the deterministic system.
-
Uncertainty is the monkey on the palm of Buddha. The monkey may make trouble, but it cannot turn over the palm of Buddha's hand, and Buddha (scheduler) sentences the monkey to 500 years of imprisonment and then exiles it to a hundred thousand miles, and finally incorporates it into the deterministic Buddhist system.

Just like after Enron, the principle-based international accounting standards turned around and defeated the proud and conceited rule-based US accounting standards, effectively dealing with uncertainty and avoiding being exploited. Most importantly, they are simple, effective and reliable.

This has been the best practice of the manufacturing industry for centuries, and there are countless research materials and book boxes available on the subject.
- We should be based on a centrally managed large data model standard system, not many simple types (or objects) that manage confusion,
- Validate centrally instead of everywhere.
- The large data model standard system is managed by the warehouse.
- The input data of each workshop (pure function, pipeline) is given by the warehouse scheduler to the data that has been checked to meet the standard.
- The output data of each workshop (pure function, pipeline) is checked by the warehouse and saved after meeting the standard.
- The workshops are independent, short, logically simple, clear, linearly scalable, they do not interact with each other, only with the warehouse, which guarantees simplicity, correctness and high efficiency.
- Replace "the complex and chaotic m*n object interactive network" with "1:n One scheduler for global scheduling and optimization of all workshops(pure function, pipeline).".

For the same reason, I think the development direction of concurrent and parallel programming technology is also "Fire-and-Forget", Change from focusing on "code and function development" to "data control, data flow management, data lifecycle management, data standardization system, process improvement (process reengineering), thread collaborative optimization, etc."
Existing pragmatic "Fire-and-Forget" concurrency and parallel technology: software transactional memory (STM), multi-versioned concurrency control (MVCC), git. Compared with them, the advantage of the warehouse/workshop model is that all tasks and resources are dynamically planned and globally deployed by the scheduling function, so there is no resource competition and transaction (version) conflicts, and optimal efficiency can be achieved.

Product: Standardized data
-
Warehouse: data management, sending & receiving, like: Enterprise Warehouse(DB) + MES (Manufacturing Execution System) = Database + DBMS.
- MES: Dispatch center
- It is equivalent to the ForkJoinPool that enhances support for operations research. It can optimize the execution order and resource allocation of tasks according to the task relationship, complete tasks at the fastest speed and use resources with the highest efficiency.
- It can be used as a workshop, but it is integrated with the warehouse as a DBMS. The combination of the DBMS and the database is more reasonable and the performance is higher.
- Notify thread production data by order (production plan) or inventory level
- Send the data to the thread, if the thread does not exist, create a thread.
- Fire-and-Forget: Forget after sending the data.
- Data storage

- Customized task relationship and optimization strategy
- Order (production plan)
- MES: Dispatch center

Workshop: Intelligent-thread, Super-Microservice. They can be processes, system threads, Project Loom fibers.

- Passive production: Lean Production, JIT (Just In Time) Production, production by order (production plan), pursuit of zero inventory and quick response.

Flink Stateful Functions

is more like my previous article: Everything is RMDB. -
In the
Warehouse/Workshop Model
, There is strictly no interaction between each workshop, and the "Flink Stateful Functions" diagram seems to be interactive. From this perspective,Flink Stateful Functions
only defines the warehouse, and does not strictly define the workshop. It is a state server, which is more similar to Clojure ring web server. Clojure Web Application Model: Ring is also aWarehouse/Workshop Model
-
In the
Warehouse/Workshop Model
, the vast majority of the workshop is a pipeline-function (pure function) or long-pipeline-function consisting of serially connected pipes. If not, then the side effect is at the end of the series of pipeline, similar to that, consumables such as office supplies or lubricants are sent from the warehouse to the workshop and are consumed. -
Flink Stateful Functions
did not emphasize two-way "Fire-and-Forget". -
Finally, I think it would be better if
Flink Stateful Functions
adhered to theWarehouse/Workshop Model
more strictly.
-
Note (2022-03-10):
-
Data flow is like rivers and electricity, one of the largest distributed systems on earth.
-
All parts (Warehouse,Scheduler, Workshop, Model) of the entire model can be distributed. Dataflows flow among them. Data flow is the foundation of the entire architecture and is the first class. It can be seen from the architecture diagram.
-
Manufacturing subsidiaries, sub-plants, parent companies are all distributed, Material flow and cash flow circulate between them.
-
Warehouses in the manufacturing industry, which have specialized independent external warehousing industries, and there are also distributed subsidiary warehouses, which you can map to distributed data, and they can all calculate optimal configurations according to my theory, which is completely supported by my theory.

Asynchronous is unnecessary, async/await
is a backward
and inevitably eliminated model.
From the perspective of Operations Research
,
async/await
should be abolished. When waiting,
this thread should be over. For example, in a factory,
it will not happen that one workshop stops in the middle
of the production process and waits for its products
at the door of another workshop to continue the production process.
Each workshop only interacts with the warehouse.
After the main thread (also the workshop) sends out order data,
The production plan is generated by the warehouse,
and data (messages) are sent to the relevant workshops
for production until the task is completed.
There is no waiting in the entire process,
but the production plan is generated according to the order,
with the warehouse as the center,
and each workshop independently produces in parallel.
Therefore, asynchronous technology from the perspective of management, people who understand the situation know that they are waiting for raw materials; people who do not understand the situation may mistakenly think that they are on strike. But in any case, it wastes resources greatly.
If there is waiting in an operation (thread, asynchronous thread, fiber), it must be because the operation design or the proportion of system resource allocation is unscientific. If there are tasks (data) that are not completed, all workers (threads, asynchronous threads, fibers) are not allowed to wait. This is the most basic requirement of scientific management.
Scientific Management
is committed to improving efficiency through Operations Research
.
It divides operations into indivisible monotonous operations
(threads, asynchronous threads, fibers),
and then designs the optimal combination of operations
based on resources to achieve maximum efficiency.
Among them, waiting is not allowed within an operation
(thread, asynchronous thread, fiber),
which is the most basic requirement,
and this approach is also the most convenient
for overall coordination and optimization.
The most important design tool is the Gantt chart.
The best implementation method is the warehouse/workshop model implemented by the factory,
which is also the principle of ForkJoinPool
(the basic technology of fiber),
but the ForkJoinPool's designer did not realize this
and did not provide guidance in the ForkJoinPool's user guide.
In the "Gantt Chart", there is no waiting inside a task (a bar in the chart. Thread, fiber), and all waiting is global. When waiting, the task (a bar in the chart. Thread, fiber) ends. When the resource is obtained to continue working, it is already a new task (a bar in the chart. Thread, fiber) . "async/await" has a wait inside a task (a bar in the chart. Thread, fiber), which is completely wrong. "async/await" completely does not conform to the most basic principles of "Operations Research Science"(ref01: wiki, ref02). I don't think the unscientific model can produce higher efficiency.
In the Gantt chart, the waiting point divides a large task into many smallest independent small tasks. A small task is a bar, a bar is a workshop, a workshop is a pipeline, and a pipeline is a pure function or equivalent pure function.
In addition to obtaining input parameters from the warehouse at the beginning and submitting output data to the warehouse at the end of the workshop, the workshops are independent of each other, and the workshop has nothing to do with the external environment. They do not need to know whether there is waiting or whether there is a previous step or a next step.
In this model, the system dispatch center (warehouse) can safely arrange the order of completion of tasks with the optimal algorithm.
This's a Manufacturing Execution System (MES).
"async/await" is just an unorganized, undisciplined, imprecise, and unsafe practice.
The most typical case: Amazon actually used AI to monitor and dispatch employees, which was inefficient and fired on the spot.
This method will not run out of resources (threads) or eventually block, because the warehouse (+ dispatch center = DBMS) will arrange the maximum number of workers (threads, asynchronous threads, fibers) in the system according to the optimal component (data) production ratio Quantity for production.
They are independent and do not interfere with each other. They are only responsible for doing their own work. There is no need to bother to observe and wait for resources during production. The warehouse (+ dispatch center = DBMS) is responsible for it.
This is consistent with the basic principle of ForkJoinPool.
-
It uses an infinite queue to save tasks that need to be executed
-
Use an internal queue to perform operations on tasks and subtasks that need to be executed to ensure their order of execution.
-
ForkJoinPool can use a limited number of threads to complete a lot of tasks with a parent-child relationship
-
Split a "big task" into multiple "small tasks" and hand the task to ForkJoinPool to execute
There is no direct relationship between fibers and asynchrony.
A fiber is made of two components — a continuation and a scheduler. As Java already has an excellent scheduler in the form of ForkJoinPool, fibers will be implemented by adding continuations to the JVM.
ForkJoinPool uses the warehouse/workshop model and the scientific management of operations research, which has been mentioned above. My algorithm is similar to "Project Loom", which is equivalent to the data-driven version of "Project Loom".
Fiber is more like an uber driver, not an uber employee (system thread). It does not need to bear the minimum wage, paid sick leave and unemployment benefits and other benefits, and there is no cost. Therefore, uber can almost treat the uber driver (fiber) as an unlimited resource, and dispatch the uber driver (fiber) to complete the task.
Conclusion
I just object to waiting in a thread, thinking that the waiting point is the natural boundary of the thread, and the thread should be terminated when there is a wait. The processing after the waiting point is solved by the dispatch center issuing new threads as needed.

Many large enterprises have independent information systems produced by different manufacturers and need to integrate and integrate.
- Workshop: individual subsystems
- Warehouse: The information system integration layer acts as a individual system.
- A unified abstraction layer (virtual database, virtual data warehouse) of enterprise global data, external data requests of any subsystem are requested from this system without knowing from that subsystem. Achieve the unity of the global system.
- The middle layer and data routing of system interconnection.
- Isolation change: When one subsystem changes, it does not cause chain changes of other subsystems.
- Putting the complexity in one place is better than putting it in all places.
- The subsystems are guaranteed independence, and the simplicity of each subsystem is realized.
- Ultimately, the simplicity and unity of the global system is achieved.

- Apple's Mac OS X uses an independent compatibility layer to support legacy applications of System OS.
- The integration layer is similar to an e-commerce platform (warehouse), and a shop (subsystem) is similar to a workshop, but each shop (or consumer) only needs to conduct purchase and sales activities and exchanges through the e-commerce platform.There is no need for direct communication or Pay attention to the details of how the product (data) is formed or circulated.

Computer hardware is also a factory that produces data, so it can also apply the "warehouse/workshop model", The model uses memory as the core, not the CPU. Finally, We can naturally support heterogeneous parallel computing, and the manufacturing industry system is good at mass production. and achieve the grand unification of all IT fields such as hardware, software, Internet, and Internet of Things.
- Warehouse: Memory
- Workshop: heterogeneous computing, CPU, GPU (graphics card), sound card, DSP,ASIC, FPGA, etc.
- Standardized data: data transmitted between hardware that conforms to industry standard interfaces
- Acceptance: Motherboard with standardized interfaces such as PCI, SATA, USB, etc.
- External standardized data: hard disk, flash drive, etc.
Modern computers (especially HPC) are often heterogeneous computing with many cores. From the theory of "warehouse/workshop model", It's the evaluation method of the manufacturing industry. system performance should be evaluated from two aspects:
- Maximum computing power of all workshops by type, This is the largest part production capacity.
- The speed at which the entire system (warehouse/workshop) cooperates with each other to complete a complex calculation task, This is the largest product production capacity.
Note:
- register is an implementation trick within the workshop (CPU, pure functions, pipelines) that is equivalent to local variables. Because soc already have integrated memory, it is theoretically possible not to use register.
The out-of-order execution technology of modern CPUs is a mistake (February 16, 2021)
Out-of-order execution is a product of wrong programming methodology, wrong computer architecture and weak compiler conditions.
In the "warehouse/workshop model", the workshop is an orderly and high-speed ray(pipeline). The warehouse scheduling function performs dynamic planning and unified scheduling for all workshops and resources, without conflict and competition, and runs in the optimal order and efficiency.
My computer hardware architecture design was published on February 06, 2019. One or two years later, the Apple M1 chip adopted the "warehouse/workshop model" design and was released on November 11, 2020.
- Warehouse: unified memory
- Workshop: CPU, GPU and other cores
- Products (raw materials): information, data
there's also a new unified memory architecture that lets the CPU, GPU, and other cores exchange information between one another, and with unified memory, the CPU and GPU can access memory simultaneously rather than copying data between one area and another. Accessing the same pool of memory without the need for copying speeds up information exchange for faster overall performance. reference: Developer Delves Into Reasons Why Apple's M1 Chip is So Fast
- From the introduction
- Apple M1 has not done global optimization of various core (workshop) scheduling.
- Apple M1 only optimizes the access to memory data (materials and products in the warehouse).
- Apple needs to further improve the programming language, compiler, and OS to support and promote my programming methodology.
- My architecture naturally supports heterogeneous computing, supports a wider range of workshop types than Apple M1, with greater efficiency, scalability and flexibility.
- Conclusion
- Apple M1 chip still needs a lot of optimization work, now its optimization level is still very simple, after all, it is only the first generation of works, released in stages.
Why my "warehouse/workshop model" can achieve high performance and low power consumption (take Apple M1 chip, Intel AVX-512, Qualcomm as examples)
Foxpro Database-oriented programming paradigm is the development direction of the future programming language (2021.11.07)
The future OS kernel will be a data-oriented scheduler (with Computer hardware and software integration architecture diagram)
Forecast(2021-01-19): I think Intel, AMD, ARM, supercomputer, etc. will adopt the "warehouse/workshop model"
In the past, the performance of the CPU played a decisive role in the performance of the computer. There were few CPU cores and the number and types of peripherals. Therefore, the CPU became the center of the computer hardware architecture.
Now, with more and more CPU and GPU cores, and the number and types of peripherals, the communication, coordination, and management of cores (or components, peripherals) have become more and more important, They become a key factor in computer performance.
The core views of management science and computer science are the same: Use all available resources to complete the goal with the highest efficiency. It is the best field of management science to accomplish production goals through communication, coordination, and management of various available resources. The most effective, reliable, and absolutely mainstream way is the "warehouse/workshop model".
Only changing the architecture, not changing or only expanding the CPU instruction set, not only will not affect the CPU compatibility, but also bring huge optimization space.
So I think Intel, AMD, ARM, supercomputing, etc. will adopt the "warehouse/workshop model", which is an inevitable trend in the development of computer hardware. My unified architecture and programming methodology will be vigorously promoted by these CPU companies, sweeping the world from the bottom up.
Mathematics (science)-based "Warehouse/Workshop Model" VS. "Von Neumann Architecture" that cannot prove its scientificity
The "von Neumann architecture" used by computers now has no mathematical model support. So it cannot prove its scientificity.
The biggest advantage of my "warehouse/workshop model" relative to the "von Neumann architecture": It is based on the simple, classic, and widely used in social production practice, elementary school mathematics "water input/output of the pool" as a mathematical prototype, Therefore, it is scientific.
Therefore, my "warehouse/workshop model" will surely replace the "von Neumann architecture" and become the first architecture in the computer field, and it is the first architecture to achieve a unified software and hardware.
2021-06-14 Prediction: Intel will use "RISC-V plus x86 compatibility layer" or "RISC-V plus x86 heterogeneous computing architecture" to develop a new generation of "warehouse/workshop model" CPU
Anyone can build a fast CPU. The trick is to build a fast system."

After the Apple M1 chip adopts it, it will continue to enter the field of supercomputers.

Like julia, a lisp is built into the internal core or internal representation,
and the popular grammar is used externally. Therefore,
the grammar is not a problem at all, and the compiler and the grammar
can evolve independently, go hand in hand, freely, efficiently, and flexibly.
You can do several languages at the same time,
such as Julia native support for julia and lisp syntax,
and third-party implementation of clojure syntax,
performance equivalent to native grammar.
Converting clojure grammar to lisp grammar is simpler than
native julia grammar conversion. Implementing a language on a platform
represented by a lisp is very simple, such as Racket.
Regardless of which one of the developers likes swift, python, ruby,
scala, f#
and java, all of them are implemented separately,
all of them are satisfied.
-
Warehouse
- Standard library
- Library represented by internal lisp that compiled from Code written in various external languages.
- Native compiler compiled libraries and applications
-
Workshop
- Native compiler: Get the lisp intermediate code from the repository, compile and output to the repository.
- Internal lisp core: Write code in lisp, or compile output intermediate code in other languages.
- External languages: Compile and output each language code to the warehouse. Each language does not have to interact with each other. Just interact with the repository. Multi-language on the racket language is the mechanism.
-
product standard (data interface): the req-map and resp-map of the ring
-
warehouse: the ring
-
workshop: the functions on both sides of the C/S, and Raw materials (hash-map) are transferred to each other through warehouses through interactions.
Therefore, I recommend functions with single hash-map type parameters. This parameter can be mapped to standards, datatable, database (with constraints, stored procedures, schemas, etc.) as needed. The Clojure’s immutable persistent data structure does not cause data cloning, which is suitable for this scene.

Workshop
- Problem solving: classic AI, expert system, logic programming
- Machine learning: Dynamically generate rules to the rule base.
- Case law, like behavior recognition techniques of antivirus software, identifying unknown patterns, more uncertainties
2021-04-30, It is described succinctly and completely that the method of AI application warehouse/workshop model written many years ago: "Explainable AI System use the law model and the Warehouse/Workshop Model"
- The Warehouse/Workshop Model base on management principles is good at organizing and coordinating, complementing each other's strengths, and cooperating to complete tasks.
- The law is good at resolving the differences and conflicts of different subjects.
- Because
- In modern legal society, statute law occupies an absolute dominant position.
- Statute law is higher than case law
- In the same legal system, the subordinates obey the superiors. If there is a problem with another system, they must respect each other.
- The basic principle of case law is "follow precedents",
- If the precedent is suitable for the current case, follow it;
- If the precedent does not fit the current case, then
- The court can refuse to apply precedent,
- Or establish a new legal principle and overturn the original case.
- In anti-virus software, signature recognition technology is simple, efficient, reliable, and accurate, and it is dominant.
- In modern legal society, statute law occupies an absolute dominant position.
- So
- An explainable AI system must be constructed in the following way to achieve the best results.
- The rule-based AI expert system is used as the logical reasoning framework, and the rule base (statute law) is used as the basis for interpretation.
- The dynamic rules (case law) generated by machine learning run in the rule-based AI expert system.
- Dynamic rules (case law) generated by machine learning cannot violate the rule base (statutory law).
- If the dynamic rules (case law) generated by machine learning conflict with the rule base (statute law), the system must archive it and submit it to humans to decide whether to modify the rule base (statute law) and whether to adopt dynamic rules (case law).
- In short, if you want an AI system to be a reasonable, responsible and explainable AI system, you must take up the weapon of law.
- An explainable AI system must be constructed in the following way to achieve the best results.

Extended case: robots and transformers on 2021-02-02
-
Advantage
- Speed up the robot's response time
- Enhance the ability to respond to change
- The components of the fractal system are highly independent, and have a strong group or independent task performance.
- The fractal system has strong survivability. As long as the smallest component survives, it can evolve into a fractal system again.
- Fractal systems are easy to combine and have consistent combination methods
- Fractal systems have consistent management (scheduling) methods
- Fractal system is convenient for standardization
- In a sense, the data management of a Transformer can be similar to a git repository, and the data management of all Transformers is the management of all github repositories. Git's distributed version control method allows each component of Transformers to maintain commonality and characteristics. Each component can fork and develop its own personalized version, or contribute its own parts to enhance the main version (public version). When other components (versions) are destroyed, as long as there is one component alive, it can continue to develop into a Transformer with its version.
- If a factory (battlestar, army, software, etc.) is used as a Transformer, then Transformers has a metabolic function and can develop and maintain itself until it completes its mission. For example, sending several sub-Battlestars (sub-factories) to conquer the sea of stars, Even if a sub-Battlestar fails, it can still shout: "I will be back!" :-)
-
Warehouse: Its scheduling function is the core of AI, based on the data in the warehouse, combining functional components to complete tasks.
- Robot status data
- Task data
- Environmental data
- Available functional components data
- Knowledge base
-
Workshop:
- Functional components or or combat components
- Other robots or transformers: Because the model is a fractal system, they can form a larger robot or transformers, or they can form a robot army. After all, no one stipulates that the components of a big Transformer must be physically connected together. Just like Monkey King (Sun Wukong), you can turn the chewed vellus hair into a monkey army to gather and scatter like you want. The vellus hair can do it, and other body tissues can do it better. It can be considered that Monkey King (Sun Wukong) is a fractal system composed of countless little Monkey Kings (Sun Wukong).

Finance is the simplest, unified and abstract profession. Currency as a general equivalent is an abstraction of the value of all commodities. Finance is uniformly measured by currency, calculated in accordance with accounting standards, and standardized and unified financial statements reflect financial status and operating results. From a financial point of view, the entire continuously operating enterprise is a
pure function pipeline "cash flow" system based on the warehouse/workshop model
.The role of the model: With this model, it can be like medical angiography, It can be found whether the blood vessel is hardened, narrowed, occluded, whether there is thrombosis, etc., whether it is necessary to perform vascular stent placement, vascular bypass, thrombus removal and other treatments. It can discover business management problems in a simple and intuitive way, provide directions for improving management, and introduce the best optimization algorithms for computer science.
- Standardized products: currency, general equivalent
- Warehouse:
- Finance department: Currency, general equivalent.
- Warehouse: products, raw materials, etc.
- Workshop: various production departments, administrative departments, and individuals.

In industry, the product standard is the interface, the production method (code implementation) is not limited, input the raw materials (data) that conform to the standard, and output the products (data) that conform to the standard, that’s all.
Before entering the warehouse, all data must be acceptance-checked first.
The input and output of the workshop can only be standardized data, the input-data comes from the warehouse, the output-data is acceptance-checked and sent to the warehouse.
Therefore, there will be no abnormal/error/Illegal data inside the workshop, no need to check data.
The code in the workshop is a pure function pipeline data flow, it's simple, reliable, high-performance, Easy to debug, easy to observe, easy to maintain, easy to expand.
The workshop and the workshop are independent, non-interactive, Like a Lego module or a ship's watertight compartment, internal changes or abnormalities in any one workshop do not affect other workshops.
The chief forms of beauty are order and symmetry and definiteness,
which the mathematical sciences demonstrate in a special degree.
---- Aristotle, "Metaphysica"
Only The Pure Function Pipeline Data Flow with Warehouse/Workshop Model
perfectly meets the requirements.
It is the best example of the beauty of programming.
Object-oriented and functional programming completely do not meet these three beauty requirements. The strange shapes and chaotic logic of OO&FP are not only unsightly, difficult to read and understand, and completely incompatible with the simple and repeatable requirements of industrial production.
FP and OO are overly complicated, and it is not feasible in large industries. It is also a kind of production method that emphasizes personal technology in hand workshops. Personal technology greatly affects product quality and extremely unreliable production methods.FP and OO are actually taking a detour, highly embellished and ineffectual, and produce all kinds of fail.
Excessive application of OO and FP design patterns, in addition to increasing complexity and error probability, reduce performance, without any benefit. Complex networks of relationships between objects in the OO system are also difficult to maintain.
The type system advocated by FP uses the HM type system to derive the types of parameters and return values in order not to write types by hand. This approach violates my programming aesthetic "definiteness", It is a big mistake that it creates a complex type system only to avoid doing one correct and simple thing. I think the type of handwriting is still too simple. My method is to refer to manufacturing practices, treat software as a factory that produces data, use data as the center, precisely define data (products, parts, raw materials) standards, and produce according to standards, everything It's all very simple.
I tend to construct systems with the simplest concepts and the most basic techniques, syntax, and functions. Used to implement my mind, The Pure Function Pipeline Data Flow is the simplest, stable, reliable and readable. There is a great poet Bai Juyi in China. even illiteracy understands and appreciates his poetry. I hope that my code can be understood by the junior programmer even in the most complicated system.

Simplicity, Unity, order, symmetry and definiteness.
---- Lin Pengcheng, Programming aesthetics
The chief forms of beauty are order and symmetry and definiteness,
which the mathematical sciences demonstrate in a special degree.
---- Aristotle, "Metaphysica"
My programming aesthetic standards are derived from the basic principles of science. Newton, Einstein, Heisenberg, Aristotle and other major scientists hold this view.
The aesthetics of non-art subjects are often complicated and mysterious, making it difficult to understand and learn.
The pure function pipeline data flow provides a simple, clear, scientific and operable demonstration.
Simplicity and Unity are the two guiding principles of scientific research and industrial production.
-
Unification of theories is the long-standing goal of the natural sciences; and modern physics offers a spectacular paradigm of its achievement. It can be found from the knowledge of various disciplines: the more universally applicable a unified theory, the simpler it is, and the more basic it is, the greater it is.
-
The more simple and unified things, the more suitable for large-scale industrial production.
-
Only simple can unity, only unity can be truly simple.
In the IT field, only two systems fully comply with these 5 programming aesthetics:
-
Binary system
The biggest advantage is that it makes the calculations reach the ultimate simplicity and unity, so digital logic circuits are produced, and then the large-scale industrial production methods of computer hardware are produced.

UnreasonableEconomy's comments at reddit
if you can generate a certain design language, a certain symmetry among components, and if the different levels of abstraction reflect each other to an extent it's much easier to communicate intent to the implementers, and for the implementing teams to communicate with each other. If you have a fluid, coherent design strategy which you can boil down into reusable tactics you can build out any system of any size and complexity because it will take on a certain fractal shape that anyone within (even if they are only concerned with a tiny part) can easily and fully navigate and understand, and one glance is all it takes to know whether you're clean, or approaching a death star.
of course, form should serve function, but I think that as humans we have evolved the concept of aesthetics as a subconscious, intuitive understanding of order. if we satisfy this intuition, we may be more certain that what we produced isn't a heap of chaos.
According to Taoism, water flow is the perfect substance. The water flow is always able to assume any shape as needed, sequential processing, until the mission is completed, reaching the end. The pure function pipeline data flow is like a water flow, almost the Tao.
Clojure just adds four persistent collections and some core functions to the JVM, and expresses the code with four persistent collections. It has no syntax, It can change as needed, like water flow, almost the Tao.
Tao is simplicity, Tao is the law of nature, Tao is algorithm, Tao is everything in everywhere on everytime. Tao is the great unification of everything. Therefore, Integrated Circuit Technology, Industrial Assembly Line Production Technology, Accounting, Management, Architecture etc. everything can be used as Algorithms and Software Engineering Methods. They can transform each other.
My theory has a wide range of applications, from SOC to supercomputer, from software to hardware, from stand-alone to network, from application layer to system layer, from single thread to distributed & heterogeneous parallel computing, from general programming to explainable AI, from manufacturing industry to IT industry, from energy to finance, from cash flow to medical angiography, from myth to Transformers, from the missile's "Fire-and-Forget" technology to Boeing aircraft pulse production line technology.
After I created the "Warehouse/Workshop Model", I became enlightened and achieved what Confucius said, "My Tao is consistent." That is: My doctrine can be connected by a fundamental principle (or ideology). Throughout human history:
- There are very few people who can use a fundamental principle (or ideology) to penetrate an industry theoretical system.
- Fewer people can use a fundamental principle (or ideology) to penetrate multiple industry theoretical systems.
- It is even rarer to be able to prove this fundamental principle (or ideology) with a mathematical model.
- A person who enables elementary school children to understand this fundamental principle (or ideology). Only me. Therefore, my theory is the closest to the "Tao" theory.
In traditional Chinese culture, there is an unremitting pursuit of the ultimate grand unification (Tao). There are countless people who know this concept, but in history, only a few people have achieved creative results. They all have a strong imagination, creativity and understanding. Everyone’s knowledge, experience, and interests are different. Everyone’s Tao also has an iconic personal characteristics, that is: only the personality is the Tao, similar to only the nation is the world.
This level of achievement is traditionally known as comprehending the true meaning of "Tao", and Einstein called it "true wisdom".

Software Design and Develop Automation (SDDA)
Software and hardware design is less different than software designers think,
but more different than hardware designers think.
---- Fred Brooks, Turing Award (1999), The Mythical Man-Month
The more simple and unified things, the more suitable for large-scale industrial production. Because binary makes calculations reach the ultimate simplicity and uniformity, digital logic circuits are produced, and then a large-scale industrial production method of computer hardware is produced.
Therefore, if software is to be realized as large-scale industrial production as computer hardware, software design and development is necessary to achieve the ultimate simplicity and unity.
Because the pure function pipeline data flow and the principle-based warehouse/workshop model
not only realize the ultimate simplicity and unification of software development,
but also make the software a simple and unified fractal system,
and realize the unification of software and hardware in the logical model,
Therefore, software can use computer hardware design and development methods for large-scale industrial production.
Therefore, it solves the problem of Fred Brooks.
The Pure Function Pipeline Data Flow
is the basics and the only way to SDDA.- SDDA is an innovative and revolutionary approach to develop large-scale software.
The Pure Function Pipeline Data Flow
systematically simulates an integrated circuit system, so SDDA can be implemented like electronic design automation (EDA).- Establishing a simple, unified, standardized, and systematic pipeline component library is the basis of SDDA, which is also the only correct method for SDDA. It's like EDA.
- AI selects components from the pipeline component library according to the data standard specification of initial state and final state. AI combines pipeline components that meet the data standard specification to complete the task. If there is no corresponding pipeline component, It can be automatically generated by AI (or developed manually by developers).
- Furthermore, it is integrated and automated that the design and development of software and hardware.(HSDDA).
The simplest, most scientific, most vivid, and most perfect IT theoretical system diagram. Success Story
Fools ignore complexity. Pragmatists suffer it. Some can avoid it. Geniuses remove it.
---- Alan Perlis, Epigrams in Programming.
the first recipient of the Turing Award (1966)
A founding father of Computer Science as a separate discipline
When the solution is simple, God is answering.
Everything should be as simple as possible, but not simpler.
Most of the fundamental ideas of science are essentially simple, and may, as a rule,
be expressed in a language comprehensible to everyone.
If you can't explain it simply, you don't understand it well enough.
Any intelligent fool can make things bigger, more complex, and more violent.
It takes a touch of genius -- and a lot of courage -- to move in the opposite direction.

0. It is the first grand unified theory in the field of natural sciences.
1. Its mathematical prototype is the simple, classic, vivid,
and widely used in social production practice,
elementary school mathematics "water input/output of the pool".
My theory rebuilt the theoretical foundation of the IT industry,
It makes the computer theory system fully & perfectly related
to mathematics in a simple and unified way:
from hardware integrated circuits and computer architecture,
to software programming methodology, architecture, programming language and so on.
It solve the most fundamental and core major problems in the IT industry:
The foundation and core of the IT theory lack mathematical support.
2. Perfectly defeat other messy and complex software engineering methodologies
in a simple and unified way.
3. Realize the unification of software and hardware on the logical model.
and the unification of programming technology and system architecture
through the innovative "Warehouse/Workshop Model".
the "Warehouse/Workshop Model" will surely replace the "von Neumann architecture"
and become the first architecture in the computer field,
and it is the first architecture to achieve a unified software and hardware.
Because "von Neumann architecture" lacks mathematical model support,
it is impossible to prove its scientificity.
4. Achieve a leap in software production theory
from the era of manual workshops
to the era of standardized production in large industries.
5. The basics and the only way to `Software Design and Develop Automation (SDDA)`,
SDDA is an innovative and revolutionary approach to develop large-scale software,
just like `Electronic Design Automation (EDA)`.
6. Defines the programming aesthetic standards as simplicity, Unity, order, symmetry and definiteness.
In the IT field, only it and binary system fully comply with these 5 aesthetics.
7. It is a particular outstanding and trend-setting technical achievement,
It fits perfectly with the principal claim to the "Turing Award".
I think it should win the "Turing Award", the highest award in the computer field.
If I cannot win the Turing Award, it must be that ACM lacks the ability to appreciate technology.
History will prove what I said.2020-03-07
---- Lin Pengcheng, Self-taught folk scientist
The idea of simplicity and unity is an important guiding ideology of scientific research. Unification of theories is the long-standing goal of the natural sciences; and modern physics offers a spectacular paradigm of its achievement. It can be found from the knowledge of various disciplines: the more universally applicable a unified theory, the simpler it is, and the more basic it is, the greater it is. In addition, the more simple and unified things, the more suitable for large-scale industrial production.
My theory has a wide range of applications, from SOC to supercomputer, from software to hardware, from stand-alone to network, from application layer to system layer, from single thread to distributed & heterogeneous parallel computing, from general programming to explainable AI, from manufacturing industry to IT industry, from energy to finance, from cash flow to medical angiography, from myth to Transformers, from the missile's "Fire-and-Forget" technology to Boeing aircraft pulse production line technology.
After I created the "Warehouse/Workshop Model", I became enlightened and achieved what Confucius said, "My Tao is consistent." That is: My doctrine can be connected by a fundamental principle (or ideology). Throughout human history:
- There are very few people who can use a fundamental principle (or ideology) to penetrate an industry theoretical system.
- Fewer people can use a fundamental principle (or ideology) to penetrate multiple industry theoretical systems.
- It is even rarer to be able to prove this fundamental principle (or ideology) with a mathematical model.
- A person who enables elementary school children to understand this fundamental principle (or ideology). Only me. Therefore, my theory is the closest to the "Tao" theory.
The Pure Function Pipeline Data Flow,
based on the philosophy of Taoism and the Great Unification Theory,
In the computer field, Based on mathematical models and manufacturing industry best practices, for the first time,
it was realized that the unification of hardware engineering and software engineering on the logical model.
It has been extended from Lisp language-level code and data unification
to system engineering-level software and hardware unification
.
Whether it is the appearance of the code or the runtime mechanism,
it is highly consistent with the integrated circuit system.
It has also been widely unified with other disciplines
(such as management, large industrial assembly lines, water conservancy projects, power engineering, etc.).
It's also very simple and clear, and the support for concurrency, parallelism,
and distribution is simple and natural.
There are only five basic components:
-
Pipeline (pure function)
-
Branch
-
Reflow (feedback, whirlpool, recursion)
-
Shunt (concurrent, parallel)
-
Confluence.
The whole system consists of five basic components. It perfectly achieves unity and simplicity. It must be the ultimate programming methodology.
In addition, the IT industry is still a very young and immature discipline.
The current software engineering is still at the level of manual workshops.
Pure function pipeline data flow
considers that computer hardware and software
are both a factory that produces data. It unifies the architecture of computer hardware
and software into the architecture of the manufacturing industry ("warehouse/workshop model"),
It brings a next-generation architecture ("warehouse/workshop model") to computer hardware,
It has verified its excellent performance through the Apple M1 chip.
It brings large-scale industrial production theories and methods to software engineering.
It incorporates IT industry into modern large industrial production systems,
This is an epoch-making innovative theory and method.
The modern society is an information society, IT controls everything,
penetrates everything. In my opinion, the development of IT is exactly
the same as the development of modern large-scale industrial production
systems. With the development of the IT industry,
With the development of the IT industry, data standard systems will be
widely established, improved and interconnected at the international,
national, industrial and enterprise levels, It will be precisely standardized
to every smallest part. pure function pipeline data flow
will become
the basic theory and Methods have become increasingly important,
and have become the ultimate standard method for entering textbooks and industry.
The key to the industrialization of the IT industry is to establish a complete standard system like the traditional industry. software is the pipeline for producing products (data), which is no different from traditional industrial production lines. Therefore, the software production method will adopt enterprise management ideas, develop software into something similar to a traditional industrial assembly line, input standardized raw materials (data), output standardized products (data), and store them in a warehouse (database).
From the perspective of large industrial production theory, standardizing the input raw materials (data) and output products (data) has the following advantages:
-
Mathematical model support: Its mathematical prototype is the simple, classic, vivid, and widely used in social production practice, elementary school mathematics "water input/output of the pool".
-
Architecture's definiteness
- Based on mathematical models, operations research, management science
- With 10 principles, 5 aesthetics, and 5 basic components
- The architecture can be visualized with a simple star chart and Gantt chart
- In the same case, the architecture designed by different people will be consistent and clear. The pros and cons of different people's design schemes can be accurately judged by mathematical models and operations research. For this situation, it is generally called science.
-
Fairness, Neutrality: Use data standard specifications to make it fair to different manufacturers, products, algorithms and implementations, and to achieve healthy competition.
-
Fungibility: As long as the pipeline (or product) meets the data standard specifications, it can be directly replaced.
-
Standard, Data standards (data interfaces, data specifications) are better than code interfaces.
-
Interconnectedness: As long as the pipes comply with the data standard specifications, they can be interconnected.
-
Combination: Data combination is better than code (function) combination.
-
Simplicity: Simplicity is the shortest path to a solution. -- Ward Cunningham (Wiki inventor)
-
Unity:
- Everything is a pipeline.
- Simple and uniform form is the basis of large-scale industrial production.
- Realize the unification with the theories of disciplines such as integrated circuits, business management, hydraulics and electricity, and you can refer to their theories.
- Realize the unification of programming technology and system architecture through innovative warehouse/shop model.
-
Predictability: Because the system architecture, design guidelines, and components are simple and unified, it is very clear, so the future development and changes of the system are predictable.
-
Reliability: Simplicity is prerequisite for reliability. -- Edsger W. Dijkstra (Turing Award in 1972)
-
Easy to expand: Just insert or replace pipes.
-
Easy to parallel, Can linearly scale up production (performance).
-
Observable, easy to debug, and verifiable. The data flowing between the pipes is very easy to observe, and it is easy to see where the pipes are leaking.
-
Clarity: non-IT practitioners can understand.
-
The best example of the beauty of programming.
The chief forms of beauty are order and symmetry and definiteness, which the mathematical sciences demonstrate in a special degree. ---- Aristotle, "Metaphysica"
Only
The Pure Function Pipeline Data Flow with Warehouse/Workshop Model
perfectly meets the requirements. It is the best example of the beauty of programming.
The role of the standard system can be seen from the great progress of social productivity after the traditional industry has entered the era of large industrial production from the era of manual workshops.
This method has been applied to 100,000 lines of code-level pure clojure project, which can prove the practicability of this method.
Finally, If you agree with me, please help me nominate the "Turing Award".
Imagination is more important than knowledge.
The true sign of intelligence is not knowledge but imagination.
Logic will get you from A to B, imagination will take you everywhere.
---- Albert Einstein
The key to interdisciplinary research and innovation:
Catch the simple and unified thing.
---- Lin Pengcheng
Similar to The most valuable chapter of “Code Complete”----Chapter 2 Metaphors for a Richer Understanding of Software Development, I tend to inspire readers to discover useful patterns from life, work and personal interests, which are then used as solutions for development, rather than to apply mechanically other people’s cases.
In this way there will be endless cases, there will always be endless ways to solve the problem. This is "Tao ".
Tao is change, simple and unified change.
---- Lin Pengcheng
I was asked why I didn't create several pipeline dataflow design patterns like OO and FP, and I thought, in Chinese Classic Myth Fiction "The Journey to the West", Bodhi asked the monkey if he wanted to learn Tiangang 36 change patterns
or Disha 72 change patterns
, when the monkey chose Disha 72 change patterns
, his failure has become a foregone conclusion, Bodhi who is the Taoist great God must understand the nature of the Tao, learn the laws of nature, The ever-changing truth, whether the monkey chose Tiangang 36 change patterns
, or Disha 72 change patterns
, his thoughts from then on stifled shackles, put on the invisible Tight curse, from then on can not approach "Tao ", this is not teaching, but playing monkey. :-)
Simplicity does not mean easy. The pure pipeline system is a simple system. but simplicity does not mean easy. Implementing a pure pipeline system is a systematic engineering. Hard work must be done to build a complex system into a simple and smooth pure pipeline system. This requires great wisdom and pays a lot of difficult Business Process Design (or Reengineering).
Many people think that sages have secret tricks, despise simple technology, and pursue complex,
difficult, and sophisticated technology, but this idea is completely contrary to the facts.
---- Wang Yangming,
the most famous and well-known thinker, philosopher, calligrapher,
strategist, and educator in China
In addition, As long as you have carefully read the "pure function pipeline data flow",
you will find that I only use the most basic common sense to solve the problem,
and did not use any too complicated and delicate technology.
Common sense
is human best practice
or the most widely used and reliable theory
.
Write pure functions (pipes) as much as possible, and only use "pipe symbols" to link them together.
As long as this is done, the old programming thinking will naturally gradually change
and gradually become a new programming thinking that focuses on changes in data flow,
It will eventually evolve into this programming methodology ----
the pure functional pipeline data flow and principle-based warehouse/workshop model
.
Moreover, it can reconstitut a complex system into a neat straight line hanging from a warehouse.
If there is no "pipe symbol", you can use the "assignment statement", which is applicable in any programming language.
Trying to develop an "complex parallel and concurrent systems" project, It will enable you to learn to divide tasks correctly and determine the best execution sequence (parallel and concurrent) for sub-tasks based on the "operational research". This will allow you to learn the correct system design. discover the wrong practices that general programming can't find.
-
Principles should be few and important, and should not affect flexibility and creativity. For example: Do not exceed 10 principles.
-
Principles should be simple and clear, and enforcement must be ensured.
-
Too many rules are equal to no rules, complicated and difficult to enforce, increasing the risk of loopholes, affecting flexibility and creativity.
-
Implementing software engineering is like leading soldiers to fight. Too many and too complicated military disciplines will make it difficult for soldiers to understand and execute, and the final result will be very poor.
-
Simplicity and unity must be parallel. Pure piping systems meet this principle.
-
Principles should be consistent with mainstream principles of modern industrial production.
"Eating your own dog food" is a good way to demonstrate a theory. If you cann't use a simple logical model (or example) to fully demonstrate a theory, it means that the theory isn't a practical, complete and systematic theoretical system, but can only be regarded as loose and messy practical experience.
This theory consists of the following six parts:
-
Mathematical prototype: the simple, classic, vivid, and widely used in social production practice, elementary school mathematics "water inflow/outflow of the pool".
-
Programming: pure function pipeline data flow, 5 basic pure function pipeline data flow components
-
Architecture: Warehouse/Workshop model
-
Principles: Principle-based methodology, 10 Principles
-
Quality control: simple mountain map or contour map, pure function ratio
-
Aesthetics: Simplicity, Unity, order, symmetry and definiteness.
Each component of this theory is perfectly applied and demonstrated other components, which shows that this theory is a practical, complete and systematic theoretical system.
Computer science is essentially a management science, and vice versa.

Creator of Management Science Computer School
In the field of computer science, I applied technologies such as management principles, warehouse/workshop model, and large-scale industrial standardization assembly lines to the fields of computer software, hardware, and AI, and realized the unification of computer theory.
In management science, I take the simple, classic, vivid, and widely used in social production practice, elementary school mathematics "water input/output of the pool" as the mathematical prototype, take the absolute mainstream production model (warehouse/workshop model) as an example, define and elaborate the management principles (core of management science).
It is the first mathematical define and elaborate of management principles and warehouse/workshop models, and it is the most scientific, systematic, simple, reliable, clear and operable. It uses mathematics to change management science from soft science to hard science, it has important guiding significance for management science, warehouse/workshop model optimization design, it will create great economic benefits for enterprises. For example: It can be used as a scientific basis to further optimize the pulsation production line technology of Boeing aircraft.
Whether it is an IT practitioner who takes up a management position, or a manager who becomes an IT industry executive, they can use my theory as a bridge to another kind of science.
In State of Clojure 2021 Results, it advocates pure functional pipeline programming.
First, Clojure programmers value a functional style of programming facilitating a separation of data and process. Coupled with its suite of immutable data structures, Clojure applications are often built as pipelines of data transformation functions that can be composed to implement higher-level business concepts in software. Link: State of Clojure 2021 Results at clojure.org
Regarding pure functional pipeline programming, this article is the simplest, most comprehensive, and most systematic article. It has industrial-grade reliability, simplicity and unity.
