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).

This script removes the input length limit which can trip up Plover users.

Simply install the script into TamperMonkey (Chrome) or GreaseMonkey (Firefox) and get racing.

Verifiable brute force strength

Below are table of various projects that can completely exhaust n-bits of keyspace. In other words, counting completely and fully from 0 to 2ⁿ-1.

This Gist implies no discussion about how this is relevant to quantum computing using Grover's algorithm, meet-in-the-middle or birthday attacks, or anything of the like. It's strictly a Gist about raw speed, measuring the result in bits.

If you know of other noteworthy and verifiable brute force searching projects,

Google/Blogger Image URL Parameters

This is an effort to document what is known about Google's (Blogger's/Blogspot's) image URL parameters. Some of these options were taken from existing first or third party documentation (see the links at the end of this document), but the majority is based off my own investigations.

Where to use them?
