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).

FINALLY no need for tricks!

Theming Slack for OSX

So, you love Slack, but you hate applications with large white backgrounds? Why not use Dark Mode!

Unfortunately, Slack does not have a Dark Mode, although it's on their list of possibilities.

But, don't fret - there is a solution! Because the slack native desktop apps are just wrappers around a web app, we can inject our own CSS to customize the application to our liking.

How to (OSX Only)

1. Gemfile

gem 'browserify-rails', '1.5.0' # until fix: https://github.com/browserify-rails/browserify-rails/issues/101
gem 'react-rails'

Browserify-rails allows to use browserify within assets pipeline. React-rails is here only to allow to use #react_component (and thus, prerendering).

Note that jquery-rails can be removed from Gemfile, the npm version of jquery and jquery-ujs will be used instead.

On OS X the Packed Pixels display won't automatically show up as "Retina" or "HiDPI" resolution, instead the OS will use the full resolution of the display making everything tiny. This can be changed using the 3rd party app (non-free) SwitchResX.

First, download SwitchResX.

You can play with the resolutions for the Packed Pixels which is probably listed as Color LCD (2). However not all of the HiDPI resolutions work due to an OS X bug. If you are happy with any of the ones that do work then stop here, else continue.

If you're on El Capitan or later you need to disable System Integrity Protection (temporarily) to add a custom resolution for Packed Pixels. Follow the instructions from SwitchResX creator.

Now add a Custom Resolution that is "scaled". It must be 2 pixels bigger or smaller than the native resolution in one direction (this is the OS X quirk). I found bigger makes it slightly blurry so go w
