It would ... http://www.rcode.net/blog/tlaurenzo/2008/01/08/java-filechannel-concurrent-access/ I am working on a Blackfin uClinux hardware project that requires a real-time SPI driver. I know that the RTDM community is looking to create profiles for various devices, but to my knowledge, nothing has been done for SPI controllers yet. This driver is targeted at the Blackfin 537 running ... http://www.rcode.net/blog/tlaurenzo/2007/04/14/xenomai-rt-spi-driver-for-blackfin/ I have been developing with Xenomai on a real-time embedded project and just got around to getting my desktop system rigged up with Adeos and Xenomai. I had been primarily doing driver development on the embedded platform, so I didn't need Xenomai on my PC. However, I am ... http://www.rcode.net/blog/tlaurenzo/2007/03/03/xenomai-230-on-ubuntu-610/ Just found these somewhat aged articles from Tim O'Reilly: Web 2.0 and Databases: Part 1 I couldn't find later parts. http://www.rcode.net/blog/tlaurenzo/2007/01/09/scaling-and-web-20/ http://pwdemo.rcode.net/svg_tester I know I'm probably late to the game on this one, but I had not realized until recently how well SVG was supported in a lot of browsers. I actually didn't realize it until I needed it for a visually rich application prototype I'm working on. I really ... http://www.rcode.net/blog/tlaurenzo/2006/08/30/embedded-svg/ For the past several months I don't think I ever had a positive thing to say in the same sentence as "Internet Explorer". Well, that has changed now. I've been delaying pulling down the IE 7 betas for fear of how difficult my life would become in trying ... http://www.rcode.net/blog/tlaurenzo/2006/08/15/ie7-beta-3-javascript-dom-speed/ I'm getting ready to take my first Protowidget application to production, and its time to address one of those things that sometimes makes me wake up at night in a cold sweat: I'm writing all of this JavaScript code and its getting huge.

If you want to skip my explanation and just see the goods, download and run the attached demo rails app or browse to http://pwdemo.rcode.net/ and click on the "Server Shared State" section on the left (please be kind to this ... http://www.rcode.net/blog/tlaurenzo/2006/07/07/protowidget-preview-with-object-graph-serialization/ In any new environment I try to avoid it for as long as possible, but eventually the kludges of trying to get an object graph from point A in tool X to point B in tool Y add up to an amount that justifies creating some generic marshaling tools. The problem ... http://www.rcode.net/blog/tlaurenzo/2006/07/05/serialization-with-javascript/ I was messing around today with trying to duplicate the way that gmail supports file uploading in the background. I didn't reverse engineer anything but worked solely from what I figured they must be doing based on what I saw of their interface.
