Falsehoods programmers believe about time

This is a compiled list of falsehoods programmers tend to believe about working with time.

Don't re-invent a date time library yourself. If you think you understand everything about time, you're probably doing it wrong.

Falsehoods

There are always 24 hours in a day.
February is always 28 days long.
Any 24-hour period will always begin and end in the same day (or week, or month).

[WIP]

Windows/MSYS2

In Windows we build using the toolchain provided by MSYS2 - the resulting binaries DO NOT link against the MSYS2 runtime.

Start by installing the necessary dependencies

Electron apps

Slide deck frameworks supporting Markdown source

Semantic Commit Messages

See how a minor change to your commit message style can make you a better programmer.

Format: <type>(<scope>): <subject>

<scope> is optional

Example

Commit Message Guidelines

Short (72 chars or less) summary

More detailed explanatory text. Wrap it to 72 characters. The blank
line separating the summary from the body is critical (unless you omit
the body entirely).

Write your commit message in the imperative: "Fix bug" and not "Fixed
bug" or "Fixes bug." This convention matches up with commit messages

Please see the most up-to-date version of this protocol on my blog at https://darencard.net/blog/.

Automatically push an updated file whenever it is changed

Linux

Make sure inotify-tools is installed (https://github.com/rvoicilas/inotify-tools)
Configure git as usual
Clone the git repository of interest from github and, if necessary, add file you want to monitor
Allow username/password to be cached so you aren't asked everytime

1.) Download a Nerd Font

2.) Unzip and copy to ~/.fonts

3.) Run the command fc-cache -fv to manually rebuild the font cache
