This is an incomplete, ever-changing curated list of content to assist people into the worlds of Data Science and Machine Learning. If you have a recommendation for something to add, please let me know. If something isn't here, it doesn't mean I don't recommend it, I just may not have had a chance to review it yet or not.

I will generally list things in order of easier to more formal/challenging content.

It may feel like there is an overwhelming amount of stuff for you to learn (because there is). But, there is a guided path that will get you there in time. You need to focus on Linear Algebra, Calculus, Statistics and probably Python (or R). Your best bet is to get a Safari Books Online account (https://www.safaribooksonline.com) which you may already have access to through school or work. If not, it is a reasonable way to get access to a tremendous number of books and videos.

I'm not saying you will get what you need out of everything here, but I have read/watched at least some of all of the following an

Preventing users from using shell escapes

Certain programs, especially text editors and pagers, have a handy shell escape feature. This allows a user to run a shell command without having to exit the program first. For example, from the command mode of the Vi and Vim editors, someone could run the ls command by doing :!ls.

You can fix this problem by having sudoedit instead of vim:

<USERNAME>     ALL=(ALL)     sudoedit /etc/ssh/sshd_config

Tired of updating your IP address manually in the security group eveytime you need to access a EC2 instance? Look no further :)

TL;DR

$ mkdir ~/.aws/cli

$ cat >> ~/.aws/cli/alias

update-ssh-ip =

<?php
$memcache = new Memcache();
$memcache->addServer(‘172.16.0.1’, 11211);
$memcache->addServer(‘172.16.0.2’, 11211);

$myData = $memcache->get(‘myKey’);
if ($myData == false) {
   $myData = GetMyDataFromDB();
 // Put it in Memcache as ‘myKey’, without compression, with no expiration
