Dazed & Confused

The Struts 2.0 development has been closed down. Struts Shale will be a new codebase for web development. No surprise that Struts would move to closer JSF integration, but dropping the entire codebase is a bit surprising.

Roy Osherove has a good piece here called Invest in the design of the system every day. He’s got it nailed:

Alright. I’ve been wrestling with my Exim configuration the last couple of days. It seems I have to learn all the commands all over each time I find a problem so here is a short list for me to remember:

exim4 -Mlv [msg-id] : list history
exim4 -Mlb [msg-id] : list body
exim4 -Mlh [msg-id] : list header
