• SNIReadSync executing between 120-500 ms for a simple query. What do I look for?

  - by Mike

  Hi Stackoverflow, I am executing a simple query against SQL Server 2005: protected static void InitConnection(IDbCommand cmd) { cmd.CommandText = "set transaction isolation level read uncommitted "; cmd.ExecuteNonQuery(); } Whenever I profile with dotTrace 3.1, it claims that SNIReadSync method is taking between 100 - 500 ms. What sort of things do I need to be looking for in order to get this time down? Thanks!

• Help me choose a CSS framework: 960 vs Blueprint vs ???

  - by Christian Perry

  I've been looking at different CSS frameworks. The two major players seem to be 960.gs and Blueprint. My question is simple: what are the pros and cons to each, and which do you recommend? And are there other frameworks that I should consider instead? Putting my question into context, I'm the designer on a site that's similar to StackOverflow, but with a general audience focus, rather than a specific technical one.

• Cover flow in iPhone/iPad

  - by hgpc

  I use FlowCoverView (http://chaosinmotion.com/blog/?p=295) for cover flow, which I discovered through this question: http://stackoverflow.com/questions/767048/iphone-coverflow FlowCoverView last update was in mid-2009 and it's performance is not very good when the images are taken from the documents directory. Yet, there are lots of apps with cover flow. I was wondering if we all use FlowCoverView, or if there's is a better, maybe iPad-optimized solution that I haven't heard about yet. What do you use to implement cover flow in iPhone/iPad?

• General Purpose Language to build a compiler for

  - by Brownie

  Inspired by Eric Sink's interview on the stackoverflow podcast I would like to build a full compiler in my spare time for the learning experience. My initial thought was to build a C compiler but I'm not sure whether it would take too much time. I am wondering if there is a smaller general purpose language that would be more appropriate to implement as a first compiler effort? Or is a C implementation doable on a reasonable timescale (200 hrs)? It is my intention to target the CLR.

  I need to build a quick feasibility test / proof-of-concept of a remote database for a client, that will be populated with mostly-typical Company and People data (names, addresses, etc); 150K records or so. The sample databases mentioned here were helpful: http://stackoverflow.com/questions/57068/good-databases-with-sample-data ...but, I'd like to be able to generate sample data like this easily on less-typical datasets as well. Anyone have any recommendations for off-the-shelf (or off-the-web) solutions?

  I have created an MSBuild tasks for building my projects, but for various reasons I wan't to switch to NAnt. Is there some task that would be equivalent to MSBuild's XmlMassUpdate in NAnt?

(for more info about XmlMassUpdate, here's a short usage I found on stackoverflow's site: MSBuild example) I tried with xmlPeek/xmlPoke tasks but couldn't get them to iterate a tree paths in a replacement file...

• Using logarithms to normalize a vector to avoid overflow

  - by muscicapa

  http://stackoverflow.com/questions/2293762/problem-with-arithmetic-using-logarithms-to-avoid-numerical-underflow-take-2 Having seen the above and having seen softmax normalization I was trying to normalize a vector while avoiding overflow - that is (x1 x2 x3 x4 ... xn) the normalized form for me has the sum of squares as 1.0 So what I thought of doing is s=(2*log(x1)+2*log(x2)+...+2*log(xn))/2 so the two factor can be taken off and finally the normalized vector is exp(log(x1)-s), , ..., exp(log(xn)-s) but I am evidently doing something wrong here, what?
