Parsing text input with a LL(k)-parser

by kai on 12/01/2005

This is going to be the month of the weird ideas ;) After writing all the stuff on product selection and recommendation, I'm now thinking about parsing form input with a LL(k)-parser (generated by JavaCC for example) to notice if people try to fill code into a form instead of "text content". The idea came up my mind during a discussion with a client today and for me it seems to be interesting as…

Product recommendation

by kai on 03/01/2005

During the holidays I read an interesting article on product recommendation systems for online shops. To be more precise, it was on the theory behind the algorithms and approaches used to filter the product set of an online shop to show the customer the products which might be worth having another look. If you ever bought something from Amazon, you know what I'm talking about...;) Well, finally I…

New Macromedia CF security bulletin

by kai on 12/10/2004

Macromedia published a new CF-related security bulletin tonight, which is available on http://www.macromedia.com/devnet/security/security_zone/mpsb04-10.html

The core issue is about the possibility of using CFOBJECT and CreateObject() in a so called "untrusted" or shared environment to gain access to internal system functionality.

CF/JRun Java VM monitoring

by kai on 18/09/2004

Inspired by Geoffs posting "Maximum JVM heap size for CFMX" I'll played a bit more intense with JVMStat, a tiny tool provided by Sun with the purpose of monitoring your JVM and its garbace collection. It's really amazing what it is able to show you about the internal status of your JVM. This is very helpful and interesting if you're concerned with performance tuning, stability or other…
