• Unix Men ☛ DD Command in Linux

• Matrix - Just 1 wobbly line rather then a rain!

  $ clear; sleep 5; echo 'while :; do printf "\e[32m%*s\e[0m" $(tput cols) $(shuf -e {0..1} -n $(($(tput lines) * $(tput cols)))); sleep 0.1; done'

  Remove clear; sleep 5 and echo for not doing sample!

• Matrix - Just 1 wobbly line rather then a rain! (shorter)

  $ while true; do printf "\e[32m%*s\e[0m" $(tput cols) $(shuf -e {0..1} -n $(tput cols)); sleep 0.1; done

  No sample. Try it and see the magic!

• Dominic Szablewski ☛ A Simple Archive Format for Self-Contained Executables

  The build/run instructions for the example games for high_impact were subtly wrong:

  make sokol
  ./build/game_sokol

  make sokol compiles the Sokol version, converts all assets and puts the results (executable and converted assets) into the build/ directory. So far so good. Where it falls apart is in the next line: ./build/game_sokol. The executable starts just fine, but it's looking in the current directory (./) for all the assets, can't find them and terminates.
