OpenID is another one of those "cool technologies you've never heard of" type of deals. OpenID is an open source initiative that provides a way for Web users to register their identity in one place and then use that identity anywhere on the Web that supports OpenID. This means that, as a user, you don't have to keep creating (and remembering) new user names and passwords at every site you visit. And, as a service provider, you can identify and authenticate users that show up at your site without having to do all of the user management involved in giving them access. The list of services that support OpenID is growing, but not as fast as it should be given how cool and useful OpenID is. Hopefully, this article will help with that. The idea behind OpenID is fairly simple: a Web user can get an ID from an OpenID provider and use that ID to access any Web application or service that supports OpenID.

Dimdim est une application internet de réunion à distance dans le même esprit que Ekiga ( dont je vous ai parlé il y a bien longtemps ). Le service est multi-plateformes, basé sur la technologie flash et le tout est proposé gratuitement. dimdim_home.jpg Jusque là rien d’extraordinaire mais l’outil propose 2 autres options intéressante : le tableau blanc et la possibilité de partager des fichiers en live (pps, pdf, doc, xls..). Une fois inscrit, Dimdim va vous demander quelques préférences afin de configurer un peu vos futurs meetings : * prévoir une zone d’attente avant les réunions * le type de connexion * le temps de réunion ( de 2h à 5h45 ) * nombres de participants * si vous autorisez le chat public et/ou les chats privés * tableau blanc ou non, screencast ou pas * Langue ( 4 pour le moment, pas de français )

This article explains how to set up a two-node load balancer in an active/passive configuration with HAProxy and heartbeat on Debian Etch. The load balancer sits between the user and two (or more) backend Apache web servers that hold the same content. Not only does the load balancer distribute the requests to the two backend Apache servers, it also checks the health of the backend servers. If one of them is down, all requests will automatically be redirected to the remaining backend server. In addition to that, the two load balancer nodes monitor each other using heartbeat, and if the master fails, the slave becomes the master, which means the users will not notice any disruption of the service. HAProxy is session-aware, which means you can use it with any web application that makes use of sessions (such as forums, shopping carts, etc.). From the HAProxy web site: "HAProxy is a free, very fast and reliable solution offering high availability, load balancing, and proxying for TCP and HTTP-based applications. It is particularly suited for web sites crawling under very high loads while needing persistence or Layer7 processing. Supporting tens of thousands of connections is clearly realistic with todays hardware. Its mode of operation makes its integration into existing architectures very easy and riskless, while still offering the possibility not to expose fragile web servers to the Net."

Les problèmes de montée en charge sont choses courantes pour un site ou une application web une fois atteint un certain succès. Ces derniers sont bien trop souvent négligés, généralement jusqu’au jour où se trouve atteinte la limite critique entre l’inconfort et l’instabilité. Le trend actuel veut qu’il soit à la fois plus simple et moins cher de rajouter des machines que de reprendre son code en profondeur pour l’optimiser. Encore faut-il que l’application permette un redimensionnement de ce genre sans rentrer dans une phase de refactoring complet. Évidemment, avant d’en arriver à une solution aussi lourde, il vaut mieux s’assurer que tout a été fait pour exploiter au mieux les ressources disponibles, et cela passe notamment par un peu d’optimisation côté serveur.

Le sujet était "Déboguer une application web avec FirePHP". Déboguer une application web peut rapidement devenir fastidieux. L'utilisation d'un débogueur simplifie ce processus mais il n'est pas toujours possible d'en utiliser un. FirePHP est une extension Firefox qui permet de fournir des informations de déboguage sans interférer avec l'affichage de l'application web. Cela est particulièrement pratique pour déboguer de l'Ajax par exemple.
