The best 59$, a java developer can ever invest

Wednesday, June 17, 2009

If you don’t buy this now, you’re either dumb. Or just plainly stupid. For the impatient: it’s a small jar that lets you compile/run/deploy java instantly, like php.

Converting checked exceptions to Runtime, as a language feature

Monday, November 24, 2008

You might already know how frustrating it is to add a try catch block on those java.io api and date parsing API. The reality is, when such exceptions occur, something terrible most probably happened and you don’t want your application to proceed normally. Ofcourse, you can have a try catch block and convert checked exceptions [...]
