+## Tooling Updates
+
+### [Sugarcubes]
+
+![Sugarcubes Example](sugarcubes.png)
+
+[Sugarcubes] by [@henryksloan] is a tool for designing and testing automata.
+
+Sugarcubes allows for easy creation of models used in the theory of computing.
+It is designed to be a more intuitive and useful alternative to JFLAP,
+the most popular tool for designing automata and formal languages.
+It uses macroquad for the editor, and egui for the toolbars. Sugarcubes
+currently features a fully functional finite automaton editor and simulator,
+and many other models, editing features and simulations are planned.
+
+You can check out a [live WASM demo here][Sugarcubes],
+or the [source code on Github][Sugarcubes source].

+### [Rusty Slider]
+
+![Rusty Slider code block example](rustyslider.png)
+_Supports syntax highlighting of code blocks_
+
+[Rusty Slider] by [@ollej] is a markdown slideshow viewer
+written with macroquad.
+
+The game engine Macroquad can be used for more than just games. It’s also a
+great way to quickly build multi-platform tools with graphics.
+
+It’s possible to write presentations in plain text using Markdown. The
+application runs natively on all major platforms, and can also be used within
+a browser.
+
+- Supports headers, bold/italic, blockquotes, lists, and code blocks with
+  syntax highlighting.
+- Automatically change slides.
+- Themes separated from content.
+- Toggle a CRT shader.
+
+The latest feature added was to execute bash code blocks. The output of the
+execution will be shown below the code block. This is meant to be used for
+demo purposes, to show actual results of commands.

+## Library Updates
+
+### [backroll-rs] and [GGRS]
+
+[backroll-rs] ([Discord](https://discord.gg/VuZhs9V),
+[crates.io](https://crates.io/crates/backroll)) by [@james7132] and
+[GGRS]([crates.io](https://crates.io/crates/ggrs)) by [@g_schup] are pure
+Rust implementations of the [GGPO] rollback networking library.
+
+![Evo Moment 37](rollback.jpg)
+_[Evo Moment 37](https://www.youtube.com/watch?v=JzS96auqau0):
+Only offline or with rollback!_
+
+Rollback networking is a peer-to-peer network technique designed to hide
+network latency in fast-paced games with precise inputs. Traditional techniques
+account for network transmission time by delaying the game execution, resulting
+in a sluggish game-feel. Rollback uses input prediction and speculative
+execution instead. Upon receiving inputs from remote clients, resimulation of
+incorrect game states occurs. This allows for gameplay that "feels just
+like offline". The open source standard for rollback netcode [GGPO] is used
+in successful games like Skullgirls, Guilty Gear XX Accent Core +R or
+Fightcade. For further explanation about rollback,
+[click here](https://ki.infil.net/w02-netcode.html).
+
+Two projects in Rust were independently created to provide a working
+implementation as well as helpful resources for developers.
+backroll-rs features an added abstraction for the transportation layer and
+also provides a bevy plugin, [bevy-backroll]. GGRS replaces the
+C-style callback API of GGPO with a simpler, more understandable control flow.
+The authors of both libraries recommend backroll-rs for developement,
+as it is currently more actively collaborated on.
+GGRS is recommended as a learning recource and entry point,
+with a plethora of internal documentation and explanation.
+
+The main requirement to make use of both presented libraries is determinism
+in your game execution. Resimulation requires that the result of progressing
+the game state depending on the given inputs yield the exact same results
+every time. Additionally, you need to be able to load, save and progress
+your gamestate without rendering the outcome.
+
+If you are interested in integrating rollback networking into your game or
+just want to chat with other rollback developers (not limited to Rust),
+check out the [GGPO Developers Discord]!

+### [CrystalOrb]
+
+[![CrystalOrb demo animation](crystalorb.gif)][crystalorb-demo]
+_Interactive [demo][crystalorb-demo] that uses the [Rapier] physics engine._
+
+[CrystalOrb] by [@ErnWong] is a new networking library that aims to help
+fast-paced client-server games synchronize their game state across multiple
+clients. Just like [backroll-rs] and [GGRS], each CrystalOrb client predicts
+the next game state without waiting for other remote players' inputs to arrive.
+Unlike backroll-rs's and GGRS's peer-to-peer approach which only send input
+data between its peers, CrystalOrb relies on having a server to send
+authoritative snapshots of the entire game state to each client. In response,
+each client unconditionally rolls-back to that snapshot. Although this may lead
+to higher network and memory usage, it means that CrystalOrb clients can join
+and leave at any time, and games that cannot guarantee full-determinism can
+still work with CrystalOrb.
+
+This library was written as a learning exercise for the author, and as such,
+the author warns that this library may not be suitable for serious games.
+
+There is an [interactive demo][crystalorb-demo] of CrystalOrb that features the
+[Rapier] physics engine.
