I am hoping to move these notes to https://ab.hl9.net/ soon. Due to the COVID-19 and life circumstances, I haven't been keeping this copy of my notes very up-to-date. I expect to have a new site with better organized notes by 2022.

Hello there, I am A.B. Carroll. I have been professionally developing software and acting as a systems administrator for at least 14 years, and I've been interested in and learning about programming, Linux/BSD-based systems, networking, and related internet technologies for well over 20 years.

I enjoy writing software in and am comfortable using a large variety of programming languages and environments such as Javascript, PHP, the C Language, Lua, Rust, and even proprietary things such as Apex, just to name a few. Likewise, on-going professional operations management and deployment of software such as web and database servers, with or without cloud-based infrastructure such as AWS or GCP, is usually part of the job as well. I am familiar with Linux andalso OpenBSD, NetBSD and FreeBSD where BSD can be appropriate for use.

Throughout the years of software development and management, I have accumulated a large collection of notes and information regarding my personal experiences. Most of the notes I cannot publish publicly, as they may contain trade secrets, personal information, or are just too specific to a given project.

However, as you can see, I have been reviewing them little-by-little, and begin the slow process of publishing the parts that may be useful to other people. This only represents a very small fraction of my overall main notes repository, but it is slowly growing.

Remember, I do these things to pay my bills, so it's a big deal to me. If you believe any of the notes here are incorrect, inappropriate, or anything of that nature, ... or if you just want to chat perhaps, ... feel free to contact me. I can be found on the FreeNode and OFTC IRC networks pretty much always using the nickname mr_ab.

Since this repository is written in markdown, markdown related things go first, here:

• adam-p/markdown-here wiki cheatsheet is a pretty good markup cheat sheet.
• [highlight.js languages repository] is how to find out which languages are called what using the syntax highlighting. For example, you need to use sql not mysql, but interestingly there is a pgsql, too. Just remove ".js" from the names in the directory.
