instanceof vs. HibernateProxy and inheritance

I posted something over on my blog about the exciting things that can happen when Hibernate proxies your base class to wrap an instance of your sub-class.

Debugging client-side issues without access to source

If you're trying to debug a client-side issue without having access to modify the source code, it can be very tricky to try things out - especially in IE without handy tools such as Firebug. This is where Proxomitron comes in handy.

It's a handy proxy that lets you hot-replace code before it's delivered to the browser, based upon rules that can be customised quite heavily (including using regexps).

There are also many preset filters that can be edited or copied to make things easier.
