at the moment i am helping to spread the dvds of the t3con2007 by bittorrent. all sessions of the conference are included and released unter a creative commons licence. get your copy today!

over all there are four dvds, you can fetch their torrent files over at andreas wolf’s:

* torrent of dvd1 (4337mb)
* torrent of dvd2 (4350mb)
* torrent of dvd3 (4335mb)
* torrent of dvd4 (4138mb)

the contents of the dvds can be found at ginas blog.

fellow code-monkeys,

the jsr-000283 content repository for java technology api version 2.0 is open for public review until september, the tenth 2007. go get it at jcp.org and write to jsr-283-comments (at) jcp.org to make sure your comments are heard.

december, the time for some just-for-fun-and-not-for-profit-projects. so some days ago we launched www.bigwheelers-exoticars.de. “we” is christian mueller, who did the flash-frontend, and myself. my job was the backend-coding, including gallery- and thumbnail-generation. all hail the gdlib!

the site itself focusses on automobile tuning, mainly interior- and exterior-styling. frank and andreas do some crazy things for small money. if you want some new rims, especially 18″-20″ sizes, check it out as well.

i have to correct my statement of how to understand java’s hs_err error files: the tool posted on davids blog was not coded by him but was used sun internally before. it’s still an useful tool, i guess. thanks for pointing out, dave!

i wonder how many j* languages are out there… a.sundararajan, who wrote the syntax comparision between java, groovy and jruby, i’ve suggested you before (and before), came up with a jython companion today. additionally he also compares javascript to java (who thinks that this is the same will get banned from my blog instantly ;)) in this chart.

a. sundararajan continued his comparision chart mentioned earlier, although he insists that it’s not complete and he is still learning the languages depicted. anyway, i think it gives you a nice overview of differences and what these languages have in common. for more code internals of java, groovy and (j)ruby click here.

by the way, sun hired the two main developers of jruby, so we might expect even more output of this project in the future due to full-time development.

mr. sundararajan of sun wrote a nice syntax comparision of java, groovy and jruby. worth watching while switching from one language to another.

today i published the newly implemented sha1 encoder on the mainframe8 site. its algorithm is explained in the fips publication 180-2. there is also a rfc for it.

free hashsums for everyone!

now david dice of sun came up with this script to simplify hs_err files, generated by java in case of crashes etc. it is written in perl and sounds quite promising:

The hs_err6.pl perl script parses an existing hs_err file and annotates it with additional information. In particular the script will decode the the rather cryptic “Error ID” string as well as making an attempt to decorate the module-relative offsets (e.g., [jvm.dll+0×1235]) found in native stack listings with more useful symbolic names.

i haven’t tried it yet, as i have no java application that crashes frequently. do you?
