How To Use GitHub Gists For Publishing Articles

GitHub Gists may be used not only for code snippets sharing but as a publishing platform for your articles.

Features And Restrictions Of GitHub Gists

Each gist is a git repo with restrictions and features:

• You can't create folders in any branch of the repo.
• Each file in the master branch larger than 1MB risks to be truncated so you can't add zip archive to master. But you may keep additional large files at another branches which can't be viewed on the gist page.
• If you want to use images in your article but wish non-embedded images to be hidden on the gist page then you may keep them in non-master branch and reference by .//raw//foobar.jpg.

Windows boot manager asks for BitLocker recovery key on each boot after updating GRUB

If Windows boot manager asks for BitLocker recovery key each boot then:

1. Get your recovery code from your windows account: https://account.microsoft.com/devices/recoverykey.
2. Reboot into Windows and input this code when asked.

You may check that in PowerShell (run as Administrator) you get such error:

> Suspend-BitLocker -MountPoint "C:"

Raspberry Pi Zero WH: My Sad Experience With It and How I Burned It Probably by Overclocking

Article finished on: 28.06.2019.
VERDICT: Wi-Fi barely works and connecting it via ethernet/usb to your router is another mess. I think I damaged wifi while overclocking it. Lesson learned: don't overclock RPI0.

Introduction Into Windows Subsystem for Linux 2 (WSL2) for Beginners

WSL2 allows you to use Linux programs in a Linux shell (bash) inside your Windows 10 or above. It is mostly used to run programs for terminal (textual interface, not graphical). Launching graphical Linux programs is not covered in this tutorial.

CAUTION: Most of the commands must be executed with admin privileges (Start -> type "powershell" -> press "Run as Administrator").

THIS IS A DRAFT!

There is offical wiki here: https://wiki.pine64.org/wiki/PinePhone_Pro.
PPP stands for PinePhone Pro.
PPPEE stands for PinePhone Pro Explorer Edition.
PPKB -- PinePhone KeyBoard.
OG PinePhone -- "Original Gangster" PinePhone (a precessor of PPP).

0. Keep in mind that PPP Explorer Edition is for early adopters and developers -- don't expect things work out of the box.
