A Classical Introduction to Modern Number Theory, Kenneth Ireland Michael Rosen

This script is NOT MAINTAINED

This snippet of code was posted in 2014 and slightly revised in 2016 and 2017. It was more of a quick'n'dirty script than a polished tool. It is made only for Linux and in Python 2, which has since become outdated.

I currently do not use it, and I suggest you avoid it as well. Please do not expect support for using this script.

🔥 If you need an alternative, @glaucocustodio has kindly suggested EasyVPN in this comment.

The rest of the README is left for historical purposed.

The introduction to Reactive Programming you've been missing

This tutorial as a series of videos

If you prefer to watch video tutorials with live-coding, then check out this series I recorded with the same contents as in this article: Egghead.io - Introduction to Reactive Programming.

HEY: I've turned this into a blog post, which is a little more in depth.

Death to tabs, long live spaces

Do this

Latency numbers every programmer should know

L1 cache reference ......................... 0.5 ns
Branch mispredict ............................ 5 ns
L2 cache reference ........................... 7 ns
Mutex lock/unlock ........................... 25 ns
Main memory reference ...................... 100 ns             
Compress 1K bytes with Zippy ............. 3,000 ns  =   3 µs
Send 2K bytes over 1 Gbps network ....... 20,000 ns  =  20 µs
SSD random read ........................ 150,000 ns  = 150 µs

Read 1 MB sequentially from memory ..... 250,000 ns = 250 µs
