 * @description This gist makes part of an article I'm writing about this topic (in spanish). This solution takes into account
 * the linear algebra concepts and geometrical interpretation of the transform-origin property specification, this solution
 * takes heavy inspiration from William's Candillon +3 year old video in this topic, however this solution brings it to the
 * modern day along with a huge fix that prevents the origin from being displaced by an incorrect offset calculation after
 * the first zoom interaction.
 *
 * This solution goes beyond a proof of concept as it does not have any drawbacks compared to the "only"
 * solution seen in many youtube videos, therefore making this solution viable for real world

Problem

I have two Github accounts: oanhnn (personal) and superman (for work). I want to use both accounts on same computer (without typing password everytime, when doing git push or pull).

Solution

Use ssh keys and define host aliases in ssh config file (each alias for an account).

How to?

1. Generate ssh key pairs for accounts and add them to GitHub accounts.

In computing, memoization or memoisation
is an optimization technique used primarily
to speed up computer programs by storing
the results of expensive function calls and  
returning the cached result when the same
inputs occur again.

FWIW: I'm not the author of the content presented here (which is an outline from Edmond Lau's book). I've just copy-pasted it from somewhere over the Internet, but I cannot remember what exactly the original source is. I was also not able to find the author's name, so I cannot give him/her the proper credits.

Android APK HTTPS user certificates how-to

Starting with Android Nougat, Google changed the way apps handle user certificates:

Apps that target API Level 24 and above no longer trust user or admin-added CAs for secure connections, by default.

This means that certificates issued by applications like [Charles][charles] or [mitmproxy][mitmproxy] are no longer accepted, so these proxies won't work for HTTPS traffic.

This tutorial explains what needs to be done to overcome that restriction and be able to sniff any Android app's HTTPS requests.
