UNIX

A History and a Memoir by Brian Kernighan:
https://www.youtube.com/watch?v=WEb_YL1K1Qg

What words can you make on a calculator if you hold it upside down? (31 minute of the video). On a modern Linux, command is the same:

grep '^[behilos]*$' /usr/share/dict/words | column

shall return around 190 words.

Copilot explanation of the grep command:

• grep: Searches for lines matching a pattern.
• ’^[behilos]*$’: This is the pattern being searched for.
• ^: Anchors the match to the beginning of the line.
• [behilos]*: Matches zero or more characters, each of which must be one of b, e, h, i, l, o, s.
• $: Anchors the match to the end of the line.
• /usr/share/dict/words: A file containing a list of English words (standard on many Unix-like systems).

In the 1960s-1970s, Ken Thompson co-invented the UNIX operating system along with Dennis Ritchie at Bell Labs. He also worked on the language B, the operating system Plan 9, and the language Go. He and Ritchie won the Turing Award. He now works at Google. He’ll be interviewed by Brian Kernighan of “K&R” fame. 3 weeks away from an operating system

Nim

Debian Trixie, compile some nim code to windows exe

Install some stuff

sudo apt install mingw-w64 binutils-mingw-w64

Build for linux

nim c -d:release woot.nim

Build for windows

nim --os:windows --cpu:amd64 --gcc.exe:x86_64-w64-mingw32-gcc --gcc.linkerexe:x86_64-w64-mingw32-gcc -d:release c woot.nim

Omarchy

An opinionated Arch + Hyprland Setup by DHH

https://omarchy.org

Turn a fresh Arch installation into a fully-configured, beautiful, and modern web development system based on Hyprland by running a single command. That’s the one-line pitch for Omarchy (like it was for Omakub). No need to write bespoke configs for every essential tool just to get started or to be up on all the latest command-line tools. Omarchy is an opinionated take on what Linux can be at its best.

Presentation with Typst

Produce a simple presentation template with say 3-5 different layouts that can be chosen like:

• Full page text
• Left text, right image
• Right text, left image

Main idea: Do Not use any online services, produce everything offline.

Install typst

https://github.com/typst/typst
Cargo install or whatever floats your boat.

Get test document to build

cd documents
code test.typ
# in new terminal pane
typst watch test.typ

Should rebuild any changes detected into test.pdf

Testing so far:

#set page(
  paper: "presentation-16-9",
  margin: (x: 2cm, y: 2cm),
  fill: rgb("#2e3c45ff"),
  header: align(center)[
  _Presentation_
  ],
  numbering: "1/1",

)
#set text(
  font: "Roboto",
  size: 13pt,
  fill: rgb("#96b0bfff"),
)
#set par(
  justify: true,
  leading: 0.52em,
)
#set heading(
  numbering: "1.",
)

#align(center, text(27pt)[
  *A fluid dynamic model
  for glacier flow*
])

#grid(
  columns: (1fr, 1fr),
  align(center)[
    Therese Tungsten \
    Artos Institute \
    #link("mailto:tung@artos.edu")
  ],
  align(center)[
    Dr. John Doe \
    Artos Institute \
    #link("mailto:doe@artos.edu")
  ]
)
#align(center)[
  #set par(justify: false)
  *Abstract* \
  #lorem(80)
]

= Introduction
#lorem(180)

#align(center + top)[
  #image("images/bronto.svg", width: 50%)

  _#lorem(5)_
]

Will produce something like:

Or in pdf form: typstTest.pdf
