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 reproduced a horrible GNOME shell regression that's been plaguing me and a bunch of friends for a while now.

Step 1)
Open up gedit. Put it on workspace 1 (for example, doesn't matter)

Step 2)
Open up firefox or some other app and put it on workspace 2. Also open up calculator on the same workspace.

Step 3)
Hit some shortcut to open up a new gedit window.

I use separate Firefox profiles for work and personal stuff. To distinguish those I place them on different workspaces.

• Workspace 0: firefox --no-remote -P MyJob
• Workspace 1: firefox --no-remote -P default

I have also company Slack on Workspace 0. Which usually contains links to some work stuff.

The problem
