Web Hooks / FrontPage
"Web hooks let you customize, extend and integrate the web applications you use with anything else you can access programmatically. To web developers, web hooks are a simple design pattern that only require the ability to make web requests and to store some extra data about users. To users, web hooks are a way to get events and data in realtime from their web applications. From this they can use the data however they like, empowering them with the ability to extend and integrate, and start seeing the true vision of the programmable web."
Cubicle Muses - Wave's Web of Protocols
"Google Waves uses XMPP only for server to server federation. Joe Gregorio has a good overview of the actual APIs and protocols used in Wave, but I still found it easier to create a diagram. I’m actually concerned about the different protocols and the fact that only the XMPP federation protocol is documented. The other two protocols: the json-rpc robot protocol and the GWT generated client-server protocol have no documentation. Moreover, the protocols are generated rpc protocols and make heavy use of serialized data."

Converting 11 million articles from TIFF to PDF-s on amazon EC2 & S3: Self-service, Prorated Super Computing Fun!
"I was ready to deploy Hadoop and my code on a cluster of EC2 machines. For deployment, I created a custom AMI (Amazon Machine Image) for EC2 that was based on a Xen image from my desktop machine. Using some simple Python scripts and the boto library, I booted four EC2 instances of my custom AMI. [..] thanks to the swell people at Amazon, I got access to a few more machines and churned through all 11 million articles in just under 24 hours using 100 EC2 instances, and generated another 1.5TB of data to store in S3."

I was ready to deploy Hadoop and my code on a cluster of EC2 machines. For deployment, I created a custom AMI (Amazon Machine Image) for EC2 that was based on a Xen image from my desktop machine. Using some simple Python scripts and the boto library, I booted four EC2 instances of my custom AMI. I logged in, started Hadoop and submitted a test job to generate a couple thousands articles — and to my surprise it just worked.
I then began some rough calculations and determined that if I used only four machines, it could take some time to generate all 11 million article PDFs. But thanks to the swell people at Amazon, I got access to a few more machines and churned through all 11 million articles in just under 24 hours using 100 EC2 instances, and generated another 1.5TB of data to store in S3.

A short history of btrfs [LWN.net]
"we'll take a behind-the-scenes look at the design and development of btrfs on many levels - technical, political, personal - and trace it from its origins at a workshop to its current position as Linus's root file system. Knowing the background and motivation for each step will help you understand why btrfs was started, how it works, and where it's going in the future. By the end, you should be able to hand-wave your way through a description of btrfs's on-disk format."

Video for Everybody!
Video For Everybody is very simply a chunk of HTML code that embeds a video into a website using the HTML5 <video> element which offers native playback in Firefox 3.5 and Safari 3 & 4. This is native OGG video playback in Firefox 3.5 (you get MPEG4 / H.264 playback in Safari). No plugins to install. The video is played by the browser itself. It loads quickly and doesn’t threaten to crash your browser. In other browsers that do not support <video>, it falls back to Adobe Flash. You can host locally or embed any Flash file, such as a YouTube video. If there is no Adobe Flash it provides download links.
