Introduction to Load Balancing Using Node.js - Part 1
by Ross Johnson Introduction At Mazira, a lot of what we develop takes the form of web services. While most of these are only used internally, it is still important that they are high-performance and resilient. These services need to be ready to churn through hundreds of gigabytes of documents at a moment’s notice, say, for example, if we need to reprocess one of our document clusters. Horizontal Scaling When it comes to increasing the performance of websites and web services, there are only a couple of options: increase the efficiency of the code, or scale up the server infrastructure. The Example In order to demonstrate load balancing, we first need a sample application. Listing 1: pi-server.js To run this example, put it into a file pi-server.js, browse to the folder in a command line and then execute: $ node pi-server.js 8000 Now, going to localhost:8000 in a web browser produces the following result: Figure 1: Example Pi-Server Result Load Testing Figure 2: JMeter Test Setup EDIT: Part 2

Boutons graphiques en CSS - CSS Debutant
Le bouton en image qui change d'aspect au passage de la souris est très utilisé sur les pages web. Longtemps, la majorité de ces boutons graphiques étaient animés par un javascript ou pire (car plus lourd) par un applet java. Avec les CSS, par effet "rollover", la légèreté et la simplicité est de mise pour créer de beaux boutons. Fonctionne avec : tous les navigateurs graphiques Attributs utilisés : background color display float line-height margin padding text-align ; text-decoration vertical-align width Bouton CSS simple Code (x)html Un bouton étant en général utilisé pour faire un lien vers une autre page, les sélecteurs exploités dans le code CSS seront a et a:hover pour le changement d'aspect au survol du bouton (si changement souhaité bien sûr...). Pour un seul bouton, le code html peut être le suivant : <div class="bouton"><p><a href="#">Bouton</a></p></div> Prenons maintenant deux images dont l'une servira pour le bouton au repos, et l'autre pour le survol. Code CSS Plusieurs boutons CSS
Parallel Processing on the Pi (Bramble)
Parallel processing on the Raspberry Pi is possible, thanks to the ultra portable MPICH2 (Message Passing Interface). I was keen to try this out as soon as I managed to get hold of two of these brilliant little computers (yes I'm a lucky boy). Here I'm going to show how I managed to get it all working and will display the results :)(Bramble was a name an ingenious Raspberry Pi forum member made up, not myself!) There are three ways which you can install MPICH2 (in case one doesn't seem to work for you), compiling and installing from source, my .deb package then following the rest of the tutorial, or the Python script file. Installing from source takes a while on the little Pi when not cross compiling. Install - Choose Method 1, 2 or 3 1) Simply download the script;wget and then run it as root with the command;sudo python install.py Then follow the instructions on the screen entering all of the necessary info.

scrollorama
Disclaimer: This is an experimental, just-for-fun sort of project and hasn’t been thoroughly tested. Design and build your site, dividing your content into blocks. Embed scrollorama.js after jQuery and initialize the plugin, passing the blocks class selector as a parameter. Target an element and animate its properties. The animation parameters you can use are: Hook into the onBlockChange event. scrollorama.onBlockChange(function() { alert('You just scrolled to block#'+scrollorama.blockIndex); }); Note: If you are not using the pinning feature, it is recommended you disable it.
Raspberry Pi Weather Station for schools
When I first joined the Raspberry Pi Foundation, over a year ago now, one of my first assignments was to build a weather station around the Raspberry Pi. Thanks to our friends at Oracle (the large US database company), the Foundation received a grant not only to design and build a Raspberry Pi weather station for schools, but also to put together a whole education programme to go with it. Oracle were keen to support a programme where kids get the opportunity to partake in cross-curricular computing and science projects that cover everything from embedded IoT, through networking protocols and databases, to big data. The goals of the project was ambitious. Between us we wanted to create a weather experiment where schools could gather and access weather data from over 1000 weather stations from around the globe. If you’ve been on Twitter a lot you’ll have noticed me teasing this since about March last year. This seemed like a good enough spread of data. Below is my second attempt.
