I’ve been on the move…

…and still I am! I moved to a new house, in a new town closer to the office (well… let’s say that now I have to drive in the traffic for just a little bit more that one hour instead of more that two hours I had before…), and as you can imagine I’ve been…

Help, my application crashes! No, it hangs… Uhm… we get a strange error… What…?!? (the importance of a proper problem description)

Dealing on a daily basis with customers and the problems they encounter using Microsoft technologies and products, and having to help them troubleshoot and resolve those problems, specially at the beginning of a new support call (after I pick the case up from the incoming queue and put it in my wipbin, as it’s called my…

Sweet sorrow… remote debugging (and more)

Continuing from my previous post on common causes for memory leaks, remote debugging is another ASP.NET feature that has the potentiality to either delight (uhm… am I exaggerating here…? ) a web developer or drive him completely crazy I remember 8-9 years ago, when I was a young technology passionate learning the basics of web…
