Tim is working on a Java project and has posted some Java coalface notes. Dynamic language fans and Pythonistas in particular, make sure you read right up to the last paragraph.

Searching a web page with Firefox - memories of vi
I have just figured out that "/" in Firefox allows you to search for text on a web page. No more pesky popup modal dialogs ala Ctrl-F. I like it. Brings me back to my vi days punching Ada into a VAX 11/780 on a 300 baud ADM 3A+ terminal. Those were the days...

Quantum Crypto
"Quantum mechanics is a field in which science and philosophy collide
very violently. The force of the collision sends potent particles of
wonder, bewilderment, awe and incredulity flying in all directions.
Computing is not immune to shrapnel wounds from these collisions. In
particular, cryptography is a field of computing in which quantum
mechanics looks set to make life a lot more difficult and a lot simpler
at the same time. Weird, I know, but hey, that's quantum mechanics for
you..."
Read the rest in this weeks E-Business in the enterprise column on ITWorld.

Many roads to quality JMS
Sometimes I come across developers who think that if you want to use messaging in Java then you get yourself a J2EE appserver, crack open a few MDBs...
You can certainly do that but there are also numerous standalone JMS implementations that can fit the bill - sometimes better than the appserver approach.
Carlos has assembled a useful list of Open Source implementations. The list includes those that are appserver based e.g. JBoss MQ.
As messaging move center stage as the key enabling tech of asynch WS, I suspect the JMS API will become as familiar to people as the JDBC/ODBC APIs of previous silver bullets :-)

XPath exprs as keys into Python dictionaries
Via Daily Python comes a link to Kimbro Staken's XPath based Python Dictionaries. Nice. The ability to simply intervene in dictionary lookups to do clever things is one of the most useful features of Python.
It really, really helps to avoid the sort of lexical scatology that comes from languages that rely on library functions for everything.
