Visualizing Canadian Energy Flows with d3.js Sankey diagrams

I have been working with processing.js but wanted to learn a little about d3js for visualizations, so took a look at Mike Bostock's d3.js plugin for making Sankey diagrams.

So I pulled down two documents that had energy flow diagrams for Canada:
I extracted the data from these diagrams and built these interactive Sankey energy flows:
Note that these two documents are looking at slightly different views of energy flows (and 2007 does not include Uranium), so can't be compared directly.

If you have any (preferably Canadian) datasets that could be presented in this fashion, let me know and we can collaborate in getting them into this form.

Addendum: 2012 10 26 22:28: Wow! The Economist's blog Graphic detail: Charts, maps and infographics has an article about this post: Charting Canada's energy: Go with the flow

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.
