Setting Up A Modern Webdev Toolchain
An Attempt At Explaining Category Theory
This is mostly a personal notebook of what I think I have learned. I make no guarantee about the accuracy of anything said here, I would appreciate any corrections or feedback on anything [I've ever] posted.
Parsing Bash Config Files
Many times a script is written that needs extra/persistent configuration from the user. In most languages this is no big deal, you just import your json/yaml/toml parser and you're good to go. The common thing to do for many bash scripts that require configuration is to ask the user to put another actual bash script containing variable declarations in the file:
A brief (and somewhat complete) history: In the beginning, the UNIX standard editor was `ed`, created by Ken Thompson in 1969. `ed` is a very powerful, very terse, command line interface for editing text, but user-friendliness is not one of it's strengths. In 1976 Bill Joy came along on his [ADM-3A](https://en.wikipedia.org/wiki/ADM-3A) and extended `ed` to become `ex`, and then a couple years later made a visual interface and called it `vi`. Later on, around 1988, Bram Moolenar took `Vi` and improved it with a lot more features, and around 1991 released it and called it `Vim`.
Functional Programming: a small introduction
It seems there's some confusion on why you might use functional programming methods like map/reduce/filter, and so I thought I'd write something to try and explain why I think they're useful and interesting.
Killing the Display Manager
Display managers like LightDM and SDDM come standard with many Linux distros, and I personally find them useless. I'd like to share with you how to get rid of them and gain a bit of control over how X is launched, and take back a few precious megabytes of RAM.
Vim beginner's customization guide
This article is for those who've been using Vim for a little while and have started to grasp modal editing and the powers of Vim, and now want to start customizing it. If you're completely new to Vim, I have another post describing some of the basic of learning Vim [here](/computers/vim-guide) but there are dozens of them on the internet, and Vim ships with `vimtutor` as well which is a great place to start.
Fuzzy searching for MPD in Bash
I recently came across [fzf](https://github.com/junegunn/fzf), which is an interactive line filter. By default `fzf` will fuzzy search recursively through file names in the current directory, but it also filters through stdin.
Backporting packages in Debian
Are you anxious for a new version of a particular package, and don't want to wait for someone else to submit it to backports? After a few hours of reading docs and testing this out myself I feel like I've gotten a good grasp on this, so I'd like to share what's been working for me.
