Git Submodules: Adding, Using, Removing, Updating (2009)

A dictionary of single-letter variable names
Haskell’s expressive type system means that type signatures can carry a lot of information. Haskell’s polymorphism means that you sometimes write functions that work across an enormous range of types, and are left wondering “what do I actually call my variables?”.

How many keywords I can fit into a single C# expression?
As I was playing few days ago with “yield return await“ I got an idea to try fit as much “keywords” as possible into one “expression”. I mean as much blue words (in Visual Studio’s default colors) as possible together (not separated by semicolon, comma, colon, bracket, etc.).

Sysop Chat
Back in mid-90s before anyone I knew had an Internet connection, a few of us had modems and would use them to call bulletin board systems via the phone line.

Sed challenge: join cal -y months into a single column
This is a little sed challenge that ocurred to me somewhat recently, when I wondered how many weeks were between 2 dates.
