The technology stack that we'll be using will be node + express + mongoDB all of which are exciting, fast and highly scalable. You'll also get to use haml-js and sass.js for driving the templated views and styling!

The simple act of making the database and the browser more powerful on either end has destroyed the need for the middle tier. In the new architecture, Our database (JSON/HTTP based: CouchDB, Cloudkit) serves data as JSON directly to the browser. On the browser side we create a much smaller/tighter ?controller? layer with JavaScript. This handles the directing of the user to the right place, the displaying of the data to the user, and the conversion of user interaction into state + data. This middle piece is jQuery + Sammy.js.

Not only does it allow you to respond to specific URLs, but utilizing the URL hash (#) you can create single page applications that still respond to the back button in your browser (ala Gmail).

This is a "behind the scenes" blog for coder.io, a soon to be launched site for programmers. What is Coder IO? (or How I Met Your Mother) In which I explain what coder.io is by looking at how to learn and keep up to date with a new developer related technology.

If you want to create your own specific chart or image crop and rotate widget, for example, you can achieve it simply and easily with this library. Rapha? uses the SVG W3C Recommendation and VML as a base for creating graphics. This means every graphical object you create is also a DOM object, so you can attach JavaScript event handlers or modify them later [tags: javascript svg graphics web] Fri, 19 Feb 2010 14:51:52 +0100 http://www.holgerarendt.de/uncommented/#3052 html5 video player [tags: html5 video web] Fri, 19 Feb 2010 14:44:51 +0100 http://www.holgerarendt.de/uncommented/#3051 Gource is a software version control visualization tool. Software projects are displayed by Gource as an animated tree with the root directory of the project at its centre. Directories appear as branches with files as leaves. Developers can be seen working on the tree at the times they contributed to the project.

You pool your spare hard drive space together with that of your friends. This forms a distributed filesystem which endures even if some of your friends' computers are unreachable. Everything is automatically encrypted, so backing up your files onto the distributed filesystem doesn't necessarily mean sharing the files with your friends. But, it is easy to share specific files or directories with specific friends. It comes with a command-line interface and a web interface. If you choose, you can allow remote HTTP clients to connect to the web interface.

HipHop programmatically transforms your PHP source code into highly optimized C++ and then uses g++ to compile it. HipHop executes the source code in a semantically equivalent manner and sacrifices some rarely used features ? such as eval() ? in exchange for improved performance.

This size is stored in the last 4 bytes of the file. This will only provide the correct value if the compressed file was smaller than 4 Gb.

The book is designed to guide you gently through using CouchDB with clear but practical scenarios. We progressively showcase key features, starting with simple document CRUD, working through to advanced MapReduce, and culminate with deployment tuning for performance and reliability.

MongoDB was used to cater to a very specific subset of the application functionality, where we felt it made a better fit than a traditional RDBMS. This hybrid architecture of data organization is turning out to be an increasingly attractive option today with more and more specialized persistent storage structures being developed [tags: nosql scala actors messaging] Mon, 25 Jan 2010 15:09:37 +0100 http://www.holgerarendt.de/uncommented/#3042 A collection of anonymously contributed client horror stories from designers.
