Effective Scala Case Class Patterns

Common Lisp Cheatsheet

Common Lisp is a general-purpose programming language with functions as first-class citizens. Don't worry about being purely functional, Lisp is Object Oriented too. CLOS is a very powerful object-oriented system!

Useful definitions

The Common Lisp lingo is quite unique:

Package: Basically a namespace, a place for symbols to live
System: Basically a Library. A bunch of code plus some instructions how it should be treated, for example which other systems it depends on, what should be loaded and/or compiled first, etc. Not in ANSI lisp but widespread. The most common system definition tool is ASDF.
Modules: Deprecated and implementation-dependent
Quicklisp: Like NPM or Ruby Gems for ASDF Systems.

Log1x's guide is pretty outdated, so I have made an updated version

Debloating Nox (Updated)

Nox, despite being the most feature-filled Android emulator, has a lot of negativity surrounding it due to their antics when it comes to making income off of their program. It is known for running repeated advertisments in the background, calling home and passing along system information (outside of your Android instance) as well as a vast amount of potentially sensitive data in an encrypted payload back to their multitude of servers. With the following preventitive measures, we can stop a majority of this happening as well as greatly improve the overall performance.

This guide is mainly targeted at Android 12. It may work on Android 5, 7 and 9 inst

Generating Authy passwords on other authenticators

*update: TBC, but this new might affect how easy it is to use this technique past August 2024: Authy is shutting down its desktop app | The 2FA app Authy will only be available on Android and iOS starting in August

This gist, based in part on a gist by Brian Hartvigsen, allows you to export from Authy your TOTP tokens you have stored there.
Those can be "standard" 6-digits / 30 secs tokens, or Authy's own version, the 7-digits / 10 secs tokens.
