While writing the last paper I'm working on, I realised I also needed to cite some web reference. As I'm used to input BibTeX entries that are papers or books, I didn't really know how to cite websites.
Apparently this is not supported by BibTeX, which is strange since the web is growing more and more important nowadays, so I found out another way to cite the online resources. This is not really the correct way to do it, as it hasn't been figured out yet, and some trick were using the @MISC type. I will use the @ONLINE type:

Lately I've been experimenting quite a lot with Raspberry Pi, but I was curious about what can Node do on Arduino. So I got an Arduino and searched for some useful library to run Node on it. I immediately found out what I was looking for : Noduino.
The framework is really easy to run: just download the branch, then upload on your Arduino the du.ino file and you are good to go. I tried a very simple example given in the repo: test.walkLED.js and...

When I first ordered my RaspberryPis, I didn't realize I would need some kind of male-to-female cables to connect the breadboard to the I/O pins on the Pis, which are male. I decided to spend I little bit more and buy the Cobbler Breakout Kits. These kits are very easy to solder and give some help in building circuits: on the board there are all the names of the pins which corresponds to the pins on the Pi. Here is one already soldered (don't mind...

Hi there. This post is not going to be on JavaScript but it will be a bit more centered on the Raspberry Pi and what I did today. As pointed out in an old blog post, I'm working on a software that creates streams of data and pass them through a topology. As data sink, I though it would be very nice to have a Raspberry Pi which gathers data from the environment, for example.
Today I started to implement something on the RPi. Nothing serious, but I...

Sometimes we need to play with timed events. JavaScript comes to the rescue giving access to setTimeout and setInterval. The first one fires only once after a certain amount of time passes, while the second one fires every time a given interval passes. For example if we give 1000 as one of the input variables to setInterval, it will fire every second.
One problem that may arise using these functions is when we want to call a function defined somewhere else and pass a parameter to it. If we try to do the following:
var myFun = function(param)...

While taking some measure on one of my softwares, I noticed instead of going through the ftp every time to get the results, I could just open some text editor. For this things I installed gedit on the Ubuntu remote machine I'm working on. I tried the following command
gedit filename.txt
Cannot open display:
Run 'gedit --help' to see a full list of available command line options.
As you can see it produced that error. The problem I had (and apparently is quite common), it's the fact that when I logged on my remote machine through ssh...

Recently I've been testing the application I'm working on. Since it is already complicated by itself I don't want to add a database support to it. Instead, I thought about writing data on a file. In the context of my software, I'm sending messages to different processes on remote machines and I want to be sure I'm not loosing any of those messages. To check this, when I receive a message I store its ID (every message has one) in a file, appending it to the end. Then by using the sort bash command I sort them and see which messages I lost (or...
