One developer, 2 servers, over 50 millions page views each day - using ASP.
2007-08-31 18:34:00
I have read Oren's post, in which he writes (again) why he thinks Asp.Net is a bad web platform. I have been reading about various tools like Ruby or MonoRail and people promoting over using simple Asp.Net. Coincidentally, I have recently listen to an Arcast episode with Markus Frind, the founder of http://plentyoffish.com/. This dude is the only employee in the "company" (acting as the

Effect of the CPU on an application
2007-08-29 23:37:00
I am working on a C4I application using GIS engine, and since the engine uses the CPU for it's calculations (not many GIS systems use the capabilities of graphics cards so far) the effect of the processor is critical in terms of performance. We recently ran a test of the same system and scenario, once with an old processor, and once with a new, faster (both in clock speed and FSB), HyperThreading

Page faults using GDI+
2007-08-25 20:02:00
I'm working on a C4I application using GIS maps. The map is refreshed (redrawn) by calling the Control.Invalidate() method.

Some times you need to measure the value of something while running the application. Using a logger is not comfortable, since you don't want to monitor gazillion rows of values. The solution: create a performance counter and use Perfmon.exe to view it while the application is running. Here is a code for creating a counter: private Perform ance Counter CreatePerformanceCounter() { string

Free and cheap WiFi in Berlin
2007-08-20 23:51:00
It has been more than a month since I got back from Berlin , so I need to backup my memory of hot spots in there: Wifi is actually pretty expansive in Berlin - there are many hot spots, but to surf you need to either pay directly to an ISP, or use your own account (assuming you have one).
