  - by Mohammad

  When Yahoo! developer guide says "Deploying your content across multiple, geographically dispersed servers will make your pages load faster from the user's perspective". And as an explanation I read somewhere, that browsers will load up to 5 things simultaneously from the same domain.

  If I have a large amount of data in memory, what is the best way to copy it into a SQL CE table? The current technology stack is C#, ADO.net, and SQL CE. My initial idea was to do one INSERT statement for each row of data, but this is time-consuming. Is there an easier way?

• jquery live tabIndex

  - by VictorS

  I have a jQuery statement that's working fine. How would I re-write it in .live? $(document).ready(function() { $(':input:enabled:visible, a:enabled:visible, span.ValidatorClass').each (function(i, e) { $(e).attr('tabindex', i) }); }); The reason I need this is that I am doing .show and .hide sometimes and need to reset tab order when that happens for the elements that appear.

• Why would you use "AS" when aliasing a SQL table?

  - by froadie

  I just came across a SQL statement that uses AS to alias tables, like this: SELECT all, my, stuff FROM someTableName AS a INNER JOIN someOtherTableName AS b ON a.id = b.id What I'm used to seeing is: SELECT all, my, stuff FROM someTableName a INNER JOIN someOtherTableName b ON a.id = b.id I'm assuming there's no difference and it's just syntactic sugar, but which of these is more prevalent/wide-spread? Is there any reason to prefer one over the other?

• Creating a java library

  - by Albinoswordfish

  This may be a silly question, but right now I have a rather large class that I want to use as a library. Where somebody can simply add this jar file to their classpath. And then simply do an import statement at the top, then he or she can start using this class. Is there anything special I need to do or can I simply just use the jar file built?

  ess-mode is "Emacs speaks statistics." This mode is useful for editing programs for R or Splus (two separate statistics packages).

Thanks, SetJmp emacs: 22.1.1 ess-mode release (unknown)

  - by Alex

  Hi all, I am looking for a regex query that would allow me to retrieve a value from a string here are examples of my string: home.aspx?StudyID=0020101&aa=72 randompage.aspx?studyid=3023603&aa=40 myconfig.aspx?studyid=0021600&aa=40 I need to get the numerical value of the 'studyid' variable, please note that the name of the page will change so simply doing the substring and counting char spaces didn't work I unfortunately cannot use request.querystring method as this string is stored in the database and a select statement will be used for running this regex query Thanks
