One thing,I am doing is doing sql profiling,and trying to fix some queries.As far caching is concerned,we have static lists.But,how to keep them updated,we don't have any server side implementation.So,these lists can be stale,if someone changes data. regards

• How to generate a unified diff in Ruby?

  - by jstayton

  After reading through this question about Ruby diff packages, I'm still not sure how to generate a unified diff from two text files. I'm not having trouble reading each file into a string (IO.read()), but I'm not finding any package that can generate a unified diff. Does one exist? Is doing a system call to diff even an option I should consider? (I'm thinking no.) Any help is appreciated! Thanks.

• Multiple accordion panes open

  - by Kevin

  We are using a jquery accordion on our site : http://www.racedayworld.com It basically lists events under each month... Apparently people are finding difficulties knowing how it really works and they don't see at first glance that there are more events under each month (that you click to expand) So I was thinking about opening two at a time (the current month and the next) .. but I'm not sure how to enable both to be open at once ... any ideas?

• Trap error or 'Resume Next'

  - by Craig Johnston

  I realise this is an older programming environment, but I have to clean up some VB6 code and I am finding that most of it uses: Resume Next What is the general consensus about the use of Resume Next? Surely, if there is an error, you would want the app to stop what it was doing, rollback any data changes, and inform the user of the error, rather than just resuming. When is it good idea to use Resume?

• Proving the ROI of a technology?

  - by leeand00

  How does one prove the ROI of a technology to their manager? The closest thing I have found to a document on how to do this is: http://www.agilejournal.com/pdf/Finding-ROI-in-Build-Automation.pdf There are formulas in this document, but I can't really tell if they are just alot of marketing or if they are accurate formulas on how to calculate ROI. I'm not really trying to calculate the ROI of the build tool in the above paper, I was just trying to calculate the ROI of a simple build tool like ANT.

• Open Source multi-touch API's?

  - by daft

  I'm looking for a good open source multi-touch API to use in a project we might get. So far I've found PyMT, but haven't really seen any comments on the maturity of that product, so any input in that regard would be much appreciated. I'd also like some other suggestions on API's that might be of interest, since googling have only given so much, and as with PyMT, it is quite difficult finding opinions on the frameworks out there. Many thanks.

• What problems are solved with R6RS Scheme's make-variable-transformer?

  - by Michael Conner

  While looking at the syntax-case section in R6RS, I saw the keyword make-variable-transformer, described as an identifier macro. The example given is very minimal, and I am not groking why it is necessary, or what use-cases require it. Finding additional examples of its use is also proving difficult. Presumably it makes some form of syntax transformation possible, or more elegant?
