The original FTB Ultimate for MC 1.4.7 crashes during startup with new versions of Java. This applies to any 1.4.7 modpack including Forestry or Railcraft. A crash might look like the following:

[SEVERE] [Railcraft] The mod Railcraft is expecting signature a0c255ac501b2749537d5824bb0f0588bf0320fa for source railcraft.jar, however there is no signature matching that description
[SEVERE] [Railcraft] Tampering Detected. Please re-download Railcraft.

Solution:

Download this file, name it java.security and save it in the instances base folder (the .minecraft folder)
Add the following Java argument to your game: -Djava.security.properties=java.security

Docker on Android 🐋📱

Edit 🎉

All packages, except for Tini have been added to termux-root. To install them, simply pkg install root-repo && pkg install docker. This will install the whole docker suite, left only Tini to be compiled manually.

Backup android app, data included, no root needed, with adb

Note: This gist may be outdated, thanks to all contributors in comments.

adb is the Android CLI tool with which you can interact with your android device, from your PC

You must enable developer mode (tap 7 times on the build version in parameters) and install adb on your PC.

Don't hesitate to read comments, there is useful tips, thanks guys for this !
