Links • November 2014

Starting now, I am going to scrub my Pocket reading list and point out interesting stuff:

• RPi Docker cloud

  These guys built a cloud of 4 Raspberry Pis using Docker and SaltStack. Very interesting read, even though, there could have been a better example than Bitcoin mining. Bonus points for using Arch Linux.

• Pixel Dungeon

  Roguelike game. Dungeons and permadeath. Highly addictive.

• Debouncing GPIO Input

  TIL: Signal bounces on connect. Also love the visualisation.

• Calculating SHA-256 with pencil and paper

  He also estimates the time and energy required to manually calculate Bitcoin hashes.

• Revisiting Android disk encryption

  Stand by and watch in awe, as Nikolay Elenkov tears apart Android’s FDE in this very detailed article. The whole blog provides a good insight into the inner workings of Android.

• Java ByteBuffer – a crash course

  Turned up in a search while I was debugging ByteBuffer bugs. Definitely contains some good points that should have been included in the Javadoc in the first place.
