02/2017: My issue with Facebook

I used to have at least one active a Facebook account, because of its conveniences, despite many ethical problems associated with using (or being used by) Facebook. But my biggest concern with Facebook is that it is actually not a “social network,” because it actually does not facilitate sharing.

01/2017: 2017 resolution: No smartphone

08/2014: Unbricking the C720 Chromebook with the BeagleBone Black or Raspberry Pi

As a regular Linux user, I am extremely happy with the Acer Chromebook C720 that I bought almost 1 year ago. The Chromebook line is one of the more libre lines of laptops that is not compromising on features, power or price. With some fixable quirks, it runs Linux (in my case, Kubuntu) almost flawlessly out of the b...

07/2013: Chumby, revisited with Bittorrent Sync

Remember the good-looking, ill-fated Chumby? The company went under on December 2011 and shut down their “cloud” services on February 2013, rendering all devices a dumb calendar widget making everyone sad.

03/2013: Streaming keygen music from my Raspberry Pi

Since I have my Raspberry Pi “server” in my butt the cloud co-lo’ed in Austria (thanks to EDIS), I wanted to make it a media server that is accessible anywhere, and supports streaming music to my computers at work as well as my Android phone.
