• Tracing memory leaks

  - by iFloh

  My favorite candidate again. I am in the process of identifying memory leaks in my app (a puzzling challenge for a newbe like me). I am using the xCode leak analyzer, but what puzzles me is how to trace back a memory leak to its variable or value. Is there a pointer to the instances that have reserved a memory address where a leak is identifyed? How do I best go about it?

• Changing keyboard layout on application focus

  - by Anonymous Coward

  Hi Everyone As everybody knows the en-US Keyboard-layout is the best one for programming. So I'd like to use it in my IDEs. But since I live in a non-en-US country I need the de-CH layout for all other applications. Now I wonder if it is possible to set the layout depending to which application currently has the focus. If that is possible, can a human brain adapt to such a behaviour or is it just confusing? cheers, AC

  - by hgpc

  I am calling a PreferenceActivity from another activity and then updating the application state (ie: changing the font size) on onActivityResult, based on the preference changes. I was thinking it would be better to put the state update logic in the PreferenceActivity. That way I don't have the duplicate the logic in each activity that calls the PreferenceActivity. What's the best or correct way to do this?

• Learn Silverlight or WPF first?

  - by Phil Wright

  It seems that Silverlight/WPF are the long term future for user interface development with .NET. This is great because as I can see the advantage of reusing XAML skills on both the client and web development sides. But looking at WPF/XAML/Silverlight they seem very large technologies and so where is the best place to get start? I would like to hear from anyone who has good knowledge of both and can recommend which is a better starting point and why.

• How do I generate a custom SID?

  - by Max Schmeling

  I need to generate custom SIDs for users in my web application for use with Microsoft AzMan. What is the best way to do this? What do I need to know before doing this? This is what I'm thinking, but I'm not sure if I'm missing something: S-1-9-1234-{user_id + 1000} S-{first revision}-{resource manager authority}-{domain (unique number for the specific app)}-{unique id for user} UPDATE: Changed to resource manager authority because of David Crawford's blog entry: http://blogs.msdn.com/dc995/archive/2006/08/23/715021.aspx

• Database structure for versioning and multiple languages

  - by phobia

  How can I solve the issue of content existing in multiple versions and multiple languages? My current structure: Each content can only have one active version in each language, and that's how I'm curious on how to best solve. Right now I have a column of the contentversions table, which means for each change of active version I have to run a update and set active=false on all version and then a update to set active=true for the piece of content in question.

That said, Lets list out some of the fastest sorts, and their best case and worst case speed in Big O notation. ~~ FlySwat ~~

• Good way to create PDF from Office documents in Java

  - by Sindri Traustason

  I'm looking for a good way to convert Office (mostly Microsoft) documents to PDF in Java. I've been looking at using the OpenOffice SDK but from the samples I've looked at it looks like this requires having OpenOffice running in server mode to do the work. Does anyone know of a good way to do this? Good meaning the less external requirements, the better. A 100% Java API would be best, but I don't expect that actually exists.
