## Which Time Is It?

By Joël Quenneville

> Can you add two time values together? Yes. No. Not so fast! <br /> <br />
>
> Reset your clocks and join me on a graphical tour of time itself. You'll discover how "time" is more than a single thing, build intuition around what different operations mean, and get a sense of when some operations are nonsensical. You'll leave with a better mental model for thinking about time and avoiding subtle time-related bugs in your own code.

## The Unbreakable Code Whose Breaking Won WWII

By Aji Slater

> After the last carrier pigeon but before digital encryption algorithms, there was the Enigma machine. An ingenious piece of pre-atomic age technology encoded German military secrets during World War II, baffling code-breakers with mere physical rotors, and switches, without elliptic curves or private keys. <br /> <br />
>
> Delve into object-oriented programming and bring the Enigma machine back to life with an emulator built in Ruby. Unravel the secrets of this nigh-unbreakable cipher device, witness OO principles unlock its mysteries, discover the power and versatility of the patterns we use as developers and how they mirror the Enigma's inner workings.
