• why does firebug debugging sometimes work and sometimes not?

  - by Edward Tanguay

  I want to debug a javascript file that is embedded in the HEAD element. I navigate to the site, see the code, and make a breakpoint: But when I click on Reload, the script disappears and it doesn't stop at the breakpoint: Debugging was working earlier so I know it works in general. What do I have to do so that Firebug always debugs my script?

• Google and Mirror Websites

  - by Roberto Aloi

  Which is the best way to manage a website with one or more mirrors so that: Google don't consider it as "dupicated content" The website is correctly indexed No inconsistencies or duplicated information are present in Google Analytics The Google webmaster guidelines in general are respected NOTE: I'm not sure if I should ask this question here or in ServerFault. It looks a bit in the middle between programming and server administration. Let me know if you think ServerFault represent a more appropriate place for this and I'll move it. Thanks.

• How can I prevent PermGen space errors in Netbeans?

  - by DR

  Every 15-30 minutes Netbeans shows a "java.lang.OutOfMemoryError: PermGen space". From what I learned from Google this seems to be related to classloader leaks or memory leaks in general. Unfortunatly all suggestions I found were related to application servers and I have no idea to adapted them to Netbeans. (I'm not even sure it's the same problem) Is it a problem in my application? How can I find the source?

• Retrieving the an SQL Agent job's specific error

  - by Tom Andrews

  I am using msdb..sp_help_job to access whether a job succeeded or failed and can retrieve a general error. But, I want to access the specific error for the step that failed. I cannot seem to find it. It is not in this list of helpful stored procedures provided by MS http://msdn.microsoft.com/en-us/library/ms187763%28v=SQL.100%29.aspx The account running the query is limited but does have the SQLUserAgent role and owns the Jobs that it is accessing.

  Are there any shortcuts to (stringByAppendingString:) string concatenation in Objective-C or shortcuts for working with NSString or other objects in general? e.g. I'd like to make this: NSString *myString = @"This"; NSString *test = [myString stringByAppendingString:@" is just a test"]; something more like this: string myString = "This"; string test = myString + " is just a test";

• Has there been a Firefox update recently?

  - by Rob Nicholson

  Has there been an update to Firefox recently? Users are reporting they are unable to use my web application when using Firefox (can't enter text into Infragistics grid). I've not changed anything recently and it works when I try with Firefox. So more of a general "Has there been an significant upgrade recently?" kind of question. Thanks, Rob.

Neither has worked... But it's still not working, I'm getting the same error. Any other ideas? Because I'm all out.

• Multiple IDE project files

  - by TomWij

  We are currently working in a team where we use both Visual Studio and Code::Blocks, is there a way to replicate changes between those project files? So if one adds a file to the project file it will also get adjusted in the project file of the other IDE? Please note: We want our project to work on multiple IDE's, platforms and compilers. Thus a general solution is welcome too.

• "Correct" way to playback user movement with xlib?

  - by Dasuraga

  I'm trying to figure out a way to make demos for a program I've written with xlib, and I came across this, but, according to the author page: This extension is not intended to support general journaling and playback of user actions. Does anyone know of any functions in xlib that are intended to support playback of user actions? Does it even exist? Or could I just use this without any real problems?

• Does visibility affect DOM manipulation performance?

  - by Chetan Sastry

  IE7/Windows XP I have a third party component in my page that does a lot of DOM manipulation to adjust itself each time the browser window is resized. Unfortunately I have little control of what it does internally and I have optimized everything else (such as callbacks and event handlers) as much as I can. I can't take the component off the flow by setting display:none because it fails measuring itself if I do so. In general, does setting visibility of the container to invisible during the resize help improve DOM rendering performance?

• Parser generator for inline documentation

  - by Leonth

  To have a general-purpose documentation system that can extract inline documentation of multiple languages, a parser for each language is needed. A parser generator (which actually doesn't have to be that complete or efficient) is thus needed. http://antlr.org/ is a nice parser generator that already has a number of grammars for popular languages. Are there better alternatives i.e. simpler ones that support generating parsers for even more languages out-of-the-box?

• professor of Java not knowing Groovy or Scala, normal or abnormal

  - by user311884

  i went to a prestigeous software conference (as dominant in its own field as MS in general), one main speaker is a professor of computer science who has been teaching Java for 20 years. During question session, he seems never heard of Groovy or Scala.... He is from a decent University in US... Is Groovy or Scala too new to attract academic attention or is this professor abnormal? thanks.

  - by Scott

  I'm very interested in this framework, coupled with a NoSQL backend like MongoDB. Basically, my blue-sky vision is this: ExtJS/Pintura/MongoDB. I would probably plug in Rhino as the js engine. Is there anybody here using Pintura in a production environment? What are the pitfalls? What is your general experience? Thanks.

• What directories do the different Application SpecialFolders point to in WindowsXP and Windows Vista

  Namely I have: Environment.SpecialFolder.ApplicationData Environment.SpecialFolder.CommonApplicationData Environment.SpecialFolder.LocalApplicationData I am unclear as to were these point to in Windows XP and/or Windows Vista. What I found so far is that the ApplicationData points to the ApplicationData Folder for the current user in XP and the roaming application data folder in Vista. I would also like to know if there are general guidelines on when to use which.

• apache vs nginx vs lighttpd? Which is simpler to configure and administer?

  - by rz

  A bit more context, in case this question is too general: the uses I have in mind are running django and serving static content and name-based virtual hosting. I am vaguely aware of the performance/resource tradeoffs between the different servers, but that is a secondary concern. Anyone who has deployed all three in production?
