Bad reputation. Lawyers have it, used-car salesmen have it, priests and clerics have it. And now computer programmers? That's what I thought when I read about the two programmers working for Bernard Madoff's Ponzi investment firm being arrested and charged with fraud. It seems that their skills were put to good use by fabricating reports — Continue reading »
Robocopy Slow on Windows Vista and Windows Server 2008
📆 June 5, 2009
A few years ago when I needed to synchronize large collection of files for a number of Windows Server 2003 hosts I stumbled upon a Windows Resource Kit utility named Robocopy. This is a great file synchronization tool with lots of switches that can quickly copy entire folders from one Windows host to another along — Continue reading »
ASP.NET Response.TransmitFile File Locking
📆 November 13, 2008
If you use the Response.TransmitFile method in your ASP.NET pages, there is a good chance that the file being transmitted is locked and unavailable for writing during that operation.

Pain and Program Exceptions
📆 January 4, 2008
Happy new year. Not so much for me. The new year was marked with a wicked lower back pain. An irritating bulging disk that gets inflamed every now and then and pinches the nerve, radiating pain everywhere. Guess that's just nature's way of manifesting my age to me. Yes I know, I'm not in my — Continue reading »
ARP, arping, and MAC
📆 December 24, 2007
Sometimes one could become so comfortable with something, that one becomes blind to the underlying technology. Such was the case with me a few days ago when I was trying to delete an IP address from one Linux node on the network and assign it to another. The problem was that the new node would — Continue reading »
