This document is guided at SDSLabs members, but should be equally valid to anyone working in technology.

I've tried to keep all advice language agnostic and independent from any technology. This is like a series of short blog posts I've condensed to a single gist. Feel free to fork and give some more of such advice.

Since I was one of the alfa-testers, I was able to develop a deployment concept for linux servers which permits to deploy BitTorrent Sync as single or multiple daemons with specific configurations. There are now ready-to-use deb packages available both for Ubuntu or Debian with full debconf-support for automated creation of an optional default configuration. If you are searching for a version more suitable for personal desktop use, please look here. Update: User @tuxpoldo has opened a repository, and keeps it current. Follow those instructions instead!

#INSTALLATION IN UBUNTU

Currently there are packages available for Ubuntu precise, quantal, raring and saucy supporting both i386 and amd64. The packages can be easily installed by adding the PPA and then installing as usual:

sudo add-apt-repository ppa:tuxpoldo/btsync
sudo apt-get update
sudo apt-get instal

Setting up a Raspberry Pi as a dashboard server with Dashing

Why the heck did I do this?

I wanted to set up one of my Raspberry Pi's as a data dashboard, pushing sensor data to a web interface that's easy to digest. I decided to use Shopify's Dashing framework. Dashing is based on Sinatra, and is pretty lightweight.

Dashing does require Ruby 1.9.3 to run. In addition, it makes use of the execjs gem, which needs to have a working Javascript interpreter available. Originally, I tried to get therubyracer working, but decided to switch over to Node.js when I ran into roadblocks compiling V8.

One warning: The RPi is a very slow system compared with modern multi-core x86-style systems. It's pretty robust, but compiling all this complex software taxes the system quite a bit. Expect that it's going to take at least half a day to get everything going.

	var response = UrlFetchApp.fetch(aUrl); // get feed
	var dataAll = JSON.parse(response.getContentText()); //
	var data = dataAll.value.items;
	for (i in data){
	data[i].pubDate = new Date(data[i].pubDate);
	data[i].start = data[i].pubDate;
	}
