Request Queuing allows your system to operate at optimal throughput. In the above example : the optimal throughput was at 500 concurrency. The concurrency at which optimal throughput is achieved is usually right below where exponential degradation starts to take place. At all times the system was operating at this optimal throughput Your users only experience linear degradation versus exponential degradation. As shown in the diagram, with no request queueing your users and your system would have experienced exponential degradation after 500 requests. Requests 0-500 take 1 second, 501-1000 takes 2 seconds, 1001-1500 take 3 seconds and so on – With Request queueing – the response times become linear Your system experiences NO degradation – This is worth repeating. The system is always operating at an optimal throughput. The only attribute that is dynamic is the queue size. The system remains in the green zone as highlighted in the diagram.
The world of scalable databases is not a simple one. They come in every race, creed, and color. Rick Cattell has brought some harmony to that world by publishing High Performance Scalable Data Stores, a nicely detailed one stop shop paper comparing scalable databases soley on the content of their character. Ironically, the first step in that evaluation is dividing the world into four groups:
Key-value stores: Redis, Scalaris, Voldmort, and Riak. Document stores: Couch DB, MongoDB, and SimpleDB. Record stores: BigTable, HBase, HyperTable, and Cassandra. Scalable RDBMSs: MySQL Cluster, ScaleDB, Drizzle, and VoltDB. The paper describes each system and then compares them on the dimensions of Concurrency Control, Data Storage Replication, Transaction Model, General Comments, Maturity, K-hits, License Language.

xtractr is a hybrid cloud application for indexing, searching, reporting, extracting and collaborating on pcaps. This enables you to rapidly identify field issues and perform network forensics and troubleshooting with just a few clicks. This lite version of xtractr can index up to 2.5 million packets or 250 Mbytes of pcaps. While xtractr can be used as a standalone application, it works best with Mu Studio to convert the problematic conversation into a stateful test case.
phpCallGraph is a tool to generate static call graphs for PHP source code. Such a graph visualizes the call dependencies among methods or functions of an application. Arrows represent calls from one method to another method. Classes are drawn as rectangles containing the respective methods. The graphs can be leveraged to gain a better understanding of large PHP applications or even to debunk design flaws in them. The example call graph on the right shows the main class of phpCallGraph itself and the internal dependencies among its methods. It is also possible to visualize calls to internal functions of PHP and to some extend call dependencies among different classes. Have a look at the example call graphs to get an impression.
The core of the call graph generator forms an object-oriented PHP5 library, which may also be integrated in other projects. It leverages the InstantSVC CodeAnalyzer and DOT. On top of it, a commandline application allows easy creation of call graphs in various formats, e.g. text, png, jpg or svg. phpCallGraph is free software licensed under GPLv3.
Cacoo is a user friendly online drawing tool that allows you to create a variety of diagrams such as site maps, wire frames, UML and network charts. Cacoo can be used free of charge.
Ca fait un petit moment déjà que j'essaie de me créer un environnement de développement distant, c'est à dire que je me connecte sur une machine en ligne pour faire ce que j'ai à faire. C'est assez sympa d'utiliser le protocol NX, il marche bien en plus. Mais je me suis très vite trouné vers une solution entièrement sur un terminal. Je zappe tout ce qui est configuration de screen, mc, finch, irssi etc.. Je vais vous présenter ma personnalisation de vim, un éditeur de texte.

Webistrano is a Web UI for managing Capistrano deployments. It lets you manage projects and their stages like test, production, and staging with different settings. Those stages can then be deployed with Capistrano through Webistrano.
Webistrano’s purpose is to make the deployment of multi-stage and multi-environment scenarios easy. Further it allows you to track who deployed what, when to which servers and be alerted by email on each deployment.
