Have you seen this sort of lizard before? My brother found this beautiful young animal near home. I heard that when this gliding lizard gets older; wing-like flaps of skin will start to grow from its abdomen. It's so peculiar
This might be a Draco Volans; a Philippine flying dragon but I'm not sure as I cannot find a picture that exactly matches it.
The mixture of colours of its skin is fascinating.

Oracle's purchase of Sun appears to have been finalised. If you visit sun.com you are redirected to oracle.com. Their developer site answers several questions including the fate of JavaOne 2010, which is the main Java conference that has been held each year in the Moscone Center in San Francisco. Here is a quote from Oracle:
Will there be a JavaOne in 2010?
Yes, there will be a JavaOne Conference in 2010. JavaOne will be co-located with Oracle Develop during Oracle OpenWorld in San Francisco from September 19-23, 2010. You may experience and register for JavaOne as a standalone conference just as before, or you can attend Oracle Develop 2010 and/or Oracle OpenWorld as well; it's your choice. Furthermore, unlike in recent years, JavaOne will focus solely on Java Technology and its associated ecosystem. You're welcome to attend Oracle Develop and Oracle OpenWorld to gain insight into specific products. As usual, all Java users and partners are invited to submit papers and to attend JavaOne.
And here's more good news: We're taking JavaOne and Oracle Develop on the road, arriving in Brazil, Russia, India, and China in 2010/2011. For the first time, the rapidly growing developer communities in those countries will have access to the JavaOne experience. Although the currently scheduled Sun Tech Days in India and Russia will continue to occur as planned, JavaOne and Oracle Develop will occur in place of Sun Tech Days thereafter.
I am very glad that JavaOne is still going ahead and it will be very interesting to compare it with previous conferences. I still need to read about the impact on other parts of Sun's business including the open source database MySQL.

I use the Squeeze aka testing distribution of Debian Linux on my dual boot computer at home. After updating the packages yesterday I discovered that java applications including Tomcat and Java Webstart were unable to connect to the network. I had no idea what was going on as I had not upgraded Java or Tomcat. After a lot of searching through the logs and then the internet I found Debian Bug #560142 and Sun bug #6342561 describing the problem. Apparently, it is related to a change in IPv6 networking in the netbase package that causes Java applications to ignore IPv4 network connections, which is rather annoying.
Fortunately, there is a simple workaround for running servers:
echo 0 > /proc/sys/net/ipv6/bindv6only
You will also have to change the default value in /etc/sysctl.d/bindv6only.conf from 1 to 0 so that the value is used after a reboot.
This means that Java is able to connect to IPv4 servers. Hopefully, this will be fixed soon but I'm glad to have found out what the problem was and to have a workaround.
Merry Christmas.

The World Wide Web Consortium (W3C) has recently updated the design of their site on www.w3.org It now uses a pleasant mix of blue and green with some shadows. For some reason, I particularly like the extra thick underlining used for the links.
For those of you who do not know what the W3C is, the following text from their site explains it:
The World Wide Web Consortium (W3C) is an international community where Member organizations, a full-time staff, and the public work together to develop Web standards
