NOTE: The Tree-sitter API and documentation has changed and improved since this guide was created. I can't guarantee this is up to date.
Tree-sitter is the new way Atom is providing language recognition features, such as syntax highlighting, code folding, autocomplete, and more. In contrast to TextMate grammars, which work by regex matching, Tree-sitter will generate an entire syntax tree. But more on that can be found in it's own docs.

Recently I have got a problem. My NUC7 refused to boot OS. The sympthom was exact as in this posting. The power button turned to solid amber/orange color (no blinking).
I've tried holding the power button for any length between 3 to 15 seconds, no changes.
Fortunately I solved the problem following an advice from Intel NUC community. The link to possible solutions is here.
I diassembled the NUC7 to reach an opposite side of the main board (with cooling fan and CMOS battery). I disconnected the battery for 15 minutes, and then connected it again. It solved the problem with power indicator and booting.
Once upon a time there was a user that wanted to install firefox.
The user tried to do pacman -S firefox
but it didn't work. The all
mighty pacman reported that firefox-3.2.4-1.i686.pkg.tar.gz
could not
be found on his mirror. So the user tried pacman -Sy firefox
. It
worked and the user rejoiced since he could once again go and troll /h/.
But all was not good. The user had made a grave error!
See, when the user told the almighty pacman to -Sy firefox
, pacman did
With wf-recorder it is possible to record one output. When ffmpeg is compiled with sdl support, then it is possible to use "sdl" as the muxer and replay the recorded video instead of writing it to a file.
I have ported this Gist to a handbook. I'll not maintain this Gist anymore, but will keep it here for future references. You can access the respective chapter in the handbook here.
In this guide you will find:
- btrfs with Zstandard compression
- LUKS-encrypted root and swapfile
- GRUB with UEFI
Download ISO from here
- choose
void-live-x86_64-YYYYMMDD.iso
- as of this writing (2020-03-20) the newest one isvoid-live-x86_64-20191109.iso
- tested on VirtualBox 6.1 with the folllowing parameters:
- system: chipset: ICH9, enable EFI, RAM: 2GB, 2 CPUs, enable nested VT-x/AMD-V
- 3 SATA hard disks hanging of AHCI controller - 2 for mirror and the other 10GB for temp installation
- IDE-CD-Rom on IDE PIIX4 controller.
