• What is a user category exactly?

  - by Andrew

  I wanted to add a tab to the user edit page ie user/%/edit/foo, and was using the twitter module as a model. After much spelunking and stepping through with a debugger, I realised that I needed to add a hook_user function in my module so that the %user_category part of the menu router path would work. It's now functioning as expected, but I don't really have a solid idea of what I just did, and haven't found a good explanation anywhere. Can anyone explain to me what it's about?

  - by Greg

  Hi, If I already have domain classes, and I want to be able persist them using EF via a model first approach how do I do this? For example do I go to the EF designer (in VS2010) and create the model and generate the classes, then go to these EF classes and somehow manually modify them? But then would there be an issue if I needed to change the model and re-create database TSQL from the model for updates? What's the easiest approach?

• How to achieve a photo "stack" border effect with CSS?

  - by Sean Gough

  I'd like to be able to add a class to images that adds a border that makes them look like a stack of photos. Anyone know how to do this? Clarifications: Ideally something like the stack shown here but it doesn't need to be interactive and only needs to work for a single photo. I also don't mind using javascript if needed (jQuery would be preferred though).

  The CSS2 box model tells us that adjoining margins collapse. I find it quite annoying, being the source of many design bugs. I hope that by understanding the purpose of collapsing margins, I will understand when to use them and how to avoid them when they are not needed. What is the purpose of this feature?

• What's a Java alternative to Google App Engine for developing iPhone Push Notification services?

  - by bpapa

  I'm a Java programmer who is working on an iPhone application. I'd like it to use Push Notification services. I originally thought I could use Google App Engine to provide the payloads to Apple, but I see now that it won't be possible because App Engine doesn't support the low-level socket programming that is needed to communicate with Apple. Are there any alternatives to Google App Engine that let me use Java? In brief, I'm wondering if there is a free hosting platform that supports Java and Socket Programming

• Do Brainbench certifications carry any weight with employers?

  - by Joshua Carmody

  Back in 2000, I got a bunch of programming certifications from Brainbench. However, they didn't seem to be doing me any good, and they needed to be renewed every year, so I let them lapse. Recently I've been hearing more about Brainbench, and I've been wondering - do these certifications impress potential employers at all, in 2009? What has been your experience?

• Syntax proposition

  - by Knowing me knowing you

  I wonder if syntax as follows would be helpful in your opinion as a code readability improvent and self-commenting of code: std::map<std::string name, std::vector<int> scores> myMap; In this example it clearly says and no other comment is needed, what for we are using myMap variable. Looking forward to your opinions.

This abstract class is now deprecated and I should use AbstractJUnit38SpringContextTests. The test class had this method in it: @Override protected boolean isDisabledInThisEnvironment(String testMethodName) { // Test is only needed for bugfixing and development.

• Android ACTION_SEND Attached File

  - by Sean

  When you attach a file to an e-mail using the ACTION_SEND intent (with the extra EXTRA_STREAM) does the e-mail app copy that attached file to its own location? My app creates a file and attaches it to an email, but this can happen many times and I would like to be able to delete this file when it is no longer needed (so it doesn't flood the user's storage with junk data). Is the file safe to delete after the e-mail intent has started?
