I like to keep an eye on trending browsers/OSs/languages etc... I find google trends is a very useful resource sometimes but other times I can not get the information I want. Example of very clear increase of Ubuntu (with 6 monthly peaks near release dates) compared with other major linux distros ecline over the years... http://www.google.com/trends?q=ubuntu%2C+debian%2C+redhat%2C+mandrake&ctab=0&geo=all&date=all&sort=0 Example of results that are skewed because of non-programming related events.

Are there any surveys anywhere which report on number of projects and/or people using the assorted Free version control systems? Also interesting is if a similar survey was one over time, to see how things have changed.

Is anyone out there using D for real world applications? If so, what are you using it for? I can't seem to find anything big on the web written in D.

I and others have had papers published in our fields based on work done using D. I think it's definitely ready for use on small to medium sized research projects where performance matters. It's a nice fit for research work because often you're starting

I'm using a customized version of Hacker News popularity algorithm for my social site (items with a number of likes and comments). The algorithm works perfectly but I don't know how to update item scorings correctly (I'm storing the score in item model as meta data). Now I'm just updating scores on every new like and comment for items listed during past 9 days. This is really slow and resource heavy so I'm looking for a better way to keep scores up to date. Problem is that every item needs a new score when one changes to keep the time decay. What would be the better way to do this? I'm using

I am a newbie and developing a website using ASP .Net 2.0 with C# 2005. I would like to add a facility to count the no. of visitors to my website.
