Midnight Commander Cheat Sheet / Shortcuts
Note for newcomers:
In the shortcuts below, "C" stands for CTRL and "A" stands for "ALT". This is a convention
used in the Midnight Commander documentation and was kept here.
You can also use "ESC" instead of "ALT", which is useful on Macbooks.

Best Practices for Clean Code
  1. Use descriptive and obvious names.
    • Don't use abbreviations, use full English words. player is better than plr.
    • Name things as directly as possible. wasCalled is better than hasBeenCalled. notify is better than doNotification.
    • Name booleans as if they are yes or no questions. isFirstRun is better than firstRun.
    • Name functions using verb forms: increment is better than plusOne. unzip is better than filesFromZip.
    • Name event handlers to express when they run. onClick is better than click.
    • Put statements and expressions in positive form.
      • isFlying instead of isNotFlying. late intead of notOnTime.
      • Lead with positive conditionals. Avoid if not something then ... else ... end.
  • If we only care about the inverse of a variable, turn it into a positive name. missingValue instead of not hasValue.

Emoji for Discord Bots

Discord Emoji

Note: This is written for those using Python 3 and discord.py, so if you're using something else please reference the relevant documentation for your language or library if you choose to use this as a general reference.

On Discord, there are two different emoji types:

Each needs to be handled differently, as while unicode emoji are just simple unicode characters, Discord custom emoji are special objects available only in Discord, belonging to a specific Discord guild and having their own snowflake ID.

Tutorial for installing a 64-bit Arch Linux ARM system on the Raspberry Pi 3B+, with an encrypted root filesystem, and the option to remotely unlock it via a pre-boot SSH daemon.

Arch Linux ARM 64 on Raspberry Pi 3 B+ With Full Disk Encryption And SSH Unlock: 2018 Edition

There are multiple ways to get a full disk encrypted arch linux system on raspberry. In this tutorial, we will install a 64-bit arch linux armv8 system, using dropbear as ssh server for remote pre-boot unlocking of the root filesystem. However, it will still be possible to unlock and use the pi as usual, with a keyboard and monitor. We will also create an unencrypted partition in the installation process, usable as a rescue system.

Differences to the 32-bit arch linux arm version:

  • probably better performance
  • can run 64-bit software
  • comes without the proprietary video-driver blobs
