What I Wish I'd Known About Equity Before Joining A Unicorn
Disclaimer: This piece is written anonymously. The names of a few particular companies are mentioned, but as common examples only.
This is a short write-up on things that I wish I'd known and considered before joining a private company (aka startup, aka unicorn in some cases). I'm not trying to make the case that you should never join a private company, but the power imbalance between founder and employee is extreme, and that potential candidates would

A bit of background on compilers exploiting signed overflow

| Why do compilers even bother with exploiting undefinedness signed overflow? And what are those | |
| mysterious cases where it helps? | |
| A lot of people (myself included) are against transforms that aggressively exploit undefined behavior, but | |
| I think it's useful to know what compiler writers are accomplishing by this. | |
| TL;DR: C doesn't work very well if int!=register width, but (for backwards compat) int is 32-bit on all | |
| major 64-bit targets, and this causes quite hairy problems for code generation and optimization in some | |
| fairly common cases. The signed overflow UB exploitation is an attempt to work around this. |
A primer/refresher on the category theory concepts that most commonly crop up in conversations about Scala or FP. (Because it's embarassing when I forget this stuff!)
I'll be assuming Scalaz imports in code samples, and some of the code may be pseudo-Scala.
A functor is something that supports map.

| min(-x,-y) = -max(x,y) | |
| abs(x) = abs(-x) | |
| abs(x) = max(x,-x) = -min(x,-x) | |
| abs(x*a) = if (a >= 0) abs(x)*a | |
| (a < 0) -abs(x)*a | |
| // basically any commutative operation | |
| min(x,y) + max(x,y) = x + y |

High-level understanding of cryptography

암호학을 사용하는 많은 시스템은 세부적으로 무슨 알고리즘을 쓰는지보다는 그 알고리즘들이 어떻게 연결되어 있는지, 즉 구조가 실제 안전성에 더 큰 영향을 미친다. 따라서 구조와 그 구조를 이루는 빌딩 블럭을 아는 것이 중요한데, 여기에서는 이러한 암호학적 빌딩 블럭과 함께 블럭들이 어떻게 쓰여서 더 큰 구조를 만드는지를 알아 본다.
키 교환. 두 사람만이 알 수 있는 새로운 키를 만든다. 이 과정이 끝나도 상대방이 내가 아는 사람인진 알 수 없지만 적어도 상대방과 내가 같은 키를 가지고 있다는 건 확신할 수 있다.
