  • it’s used to verify that OpenGL ES2 works onn your system. It’s the variant of 3D graphics drivers that is used on smartphones. Many apps nowadays write their GFX frontend with GLES2 so it uses the same code on phones and PCs, and if they compile the app to run in the web browser, WebGL is also based on GLES2.











  • This needs some simple hardware trigger, that can be queried by bootloader, but specific wnough so it won’t trigger in your pocket. If buttons are unavailable, I can propose several idead:

    • Cover the proximity sensor 10 times per second. Requires good motor skills.
    • Shine separated red, green, and blue lasers into three of the phone cameras. You’ll need a box with three different-colored LEDs to cover cameras module.
    • There is a low-speed data channel in wireless chargers. Just add the button to the charger instead of the phone.
    • Put your phone at exactly 2.5G of acceleration. Accelerometer is easy to use even from the bootloader, however you will need to put your phone in a centrifuge and reboot it while it’s rotating.
    • An option ‘Reboot into recovery’ in system settings, duh. Won’t help if your ROM fails to boot.

    I’m pretty sure Apple and Google already rewritten all important GNU parts into something with Apache or BSD license, to throw everything GPL licensed out of their embedded systems. The biggest and most important part was obviously GCC, replaced by Clang.

    How many GPL-licensed system libraries and tools are in Android right now, except for the kernel? I’m pretty sure the answer is zero.

    • Ctrl-C will not do what you expect, use Ctrl-Shift-C, or click mouse wheel
    • There are many better terminal emulators that XTerm
    • If you accidentally press Ctrl-Alt-F1, you can press Alt-F7 to switch back to the graphical desktop
    • There are in fact many ways to exit vi, no need to reboot your PC
    • There’s no need to suffer through The True Commandline Experience For Real Fedora-Wearing Sysadmins⁽¹⁾, just install mc and get all the benefits without typing cd and ls every time you want to find a specific file

    ⁽¹⁾ Real Fedora-Wearing Sysadmins don’t use vi to edit files, they either write a sed script or use cat to copy the file to the terminal, then use cat again to copy the contents of the terminal back into the file by clicking the mouse wheel while typing manually the lines they need to change.
