# lessf: `less +F` for multiple files, ala `tail -f`
#
# Usage:
#    lessf file1.log file2.log ...
#
#  - should work on dash, bash, and zsh;
#  - works on macOS and the Linuxes I've tested it on;
#  - requires the minimal tools that seem to be available nearly everywhere (`awk`, `mktemp`), and of course `less`
#  - you may want `unbuffer` or `stdbuf` to avoid the 4kb of buffering (i.e. no output until enough loglines have been added.)

Lenovo Thinkcentre M92P
When booting to USB installer disk installation proceeds as expected
1962 no operating system found
When booting into preview mode all disks load without issue, so its not the cable
Secure Boot option either not present or disabled
Last time I fixed this by adding a fake line to the boot loader from instructions on the web
Got a warning during installation about UEFI mode
Windows Fast Startup disabled

Update (March 2023) (Last checked: Oktober 2024)

Side note: The latest edge build of KeeAgent plugin offers an option for creating a WSL compatible socket. This would be very handy. I already tried to use that socket, but the socket file is currently empty and ssh inside WSL 2 is unable to use it. This appears to be a very new, unreleased and unstable feature. I will follow the development of it and when it finally works (well, for me) I will update this HOWTO. But until then, please use the proven wsl-ssh-agent/npiperelay.exe approach below.

Thanks to the instructions for WSL 2 of the wsl-ssh-agent project, KeeAgent works great in WSL 2 now: https://github.com/rupor-github/wsl-ssh-agent#wsl-2-compatibility The approach uses minimal and well-maintained tools.

# This script takes a video's individual frames and overlays them to produce a composite "long exposure" image.
#
# Usage: python expose.py video.mp4 width height
#
# IMPORTANT: you'll need to edit this script to set the value of 'alpha' appropriate for your video's length and desired brightness.
