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).

Use the Hubble app to get the camera connected to a wifi network.

Git Cheat Sheet

Getting Started

the grand idea

I like public key auth. I feel safer using them instead of a username and password login. But, I might not have my private key with me at a time where I need access.

I started using yubikey with LastPass and since I have it always on my keychain, I decided to find more ways to make use of it.

I wasn't originally aware, but if you pass a private key to ssh and sshd is configured to accept a key, it appears pam isn't used. Your authorized keys are checked and you are logged in. If you don't pass a private key, ssh falls back to the more standard un*x style login found in /etc/pam.d/sshd. This is where we'll add the yubikey pam. I am currently unaware of a way to use both public key auth and yubikey for login.

These steps worked for me on debian squeeze/wheezy.
