XML11: Amazing AJAX Toolkit
XML11 is a very exciting AJAX toolkit inspired by the X11 protocol. It allows Java applications to be rendered on a web browser, but also under Java Swing and Java AWT. In addition (and very wild), as there is an X11 server implemented (WeirdX) in Java, you can also have an X11 application working in a web browser!

Seeing xcalc and xeyes rendered on Firefox, via AJAX, WeirdX, AWT and X11 is borderline bizarre. Check out the Google TechTalks video by Arno Puder, it is quite amazing. I would have liked to have seen Firefox running inside of this convoluted set of protocols and environments inside of Firefox.

He also coins a wonderful phrase: "JavaScript is the assembly of the Web...", basically claiming that while JavaScript is fundamental to the Web (or at least AJAX), no sane person wants to use it (like assembler today: is is a "pain" to write in). You would prefer to use a proper high level programming language like Java, C++, etc. I have to agree...

Logic code can either run on the original platform (X11, Java) or can run on the client via a Java-bytecode-to-XML-to-XSLT-to-JavaScript (wow!!) cross-compiler. This is configurable at the class level, I believe. If something on the browser needs a component on the server, some transparent middleware looks after making this connection...

They are also looking at getting VNC (via a VNC Java client) to work inside of a browser, and looking at something that works with .NET...

Java, MySql increased performance with Huge Pages

[Resources updates: 2010.07.07 , 2009.11.03 , 2009.05.27 ] Long running, large memory, high performant applications often have special needs with respect to their memory management. On Linux, Solaris and other modern OSes, the translation look-aside buffer ( TLB ) - whose page size of 4k for many CPUs/OSes - becomes a scalability issue in these extreme conditions. In order to get around TLB scalability issues, huge page sizes are used to reduce the impact on performance. This can be of use to installations with large scale Java, MySql and other large memory applications. 300% improvement : " Well, in my case, I was able to achieve an over 3x improvement in my EJB 3 application, of which fully 60 to 70% of that was due to using large page memory with a 3.5GB heap. Now, a 3.5GB heap without the large memory pages didn't provide any benefit over smaller heaps without large pages. Besides the throughput improvements, I also noticed that GC frequency was cut down by two-third...

IBM on Linux: "Lean, clean, and green"

IBM developerWorks has an article ( Linux: Lean, clean, and green: How GNU/Linux is becoming more eco-friendly - 26 May 2009) which examines some of the Green benefits of the Linux operating system. It focuses primarily on the low resource demands Linux has on systems (as well as its support for older systems), thus extending the life of machines that would otherwise be junked. Also discussed is virtualization and aspects of the Linux OS that reduce power consumption in servers.

Postscript coding resources

Image
Postscript is one of my favourite programming languages. Resources for postscript programming are not too common, and are always popping up and then disappearing, as things tend to do on the Web. Here is a snapshot of links that work: I will do my best to keep them up-to-date.
