Last active October 6, 2017 12:08
Special use-case ExecutorService which collects tasks for execution and invokes them all on #flush() method in current thread. Useful for setup tests, so one can gain control of code execution scheduled by classes under test.

Wake up using ONLY power button

The script scans /proc/acpi/wakeup for all enabled entries, excluding power button and some custom hardware (like sleep buttons) and disables that entries. Especially useful if your computer wakes up on mouse movement or keyboard.

Prerequisites

  • ghc
  • cabal
  • text Haskell library
