• How do I list all files in a subdirectory in scala?

  - by Nick Fortescue

  Is there a good "scala-esque" (I guess I mean functional) way of recursively listing files in a directory? What about matching a particular pattern? For example recursively all files matching "a*.foo" in c:\temp.

• What's the difference between using ProtocolType.IP and ProtocolType.Tcp

  - by Sekhat

  I've just answered problem with sockets in c# where in my example code I initializing my socket using ProtocolType.IP as this is what I've always used in my own code, and it has never caused me problems. But I see many examples specifying ProtocolType.Tcp. I guess, what I'm asking is, by using ProtocolType.IP instead of ProtocolType.Tcp is anything being performed differently under the hood that I should be aware of?

• How do you debug your application if they got started using a custom URL scheme?

  - by stigi

  I'm developing an app for the iPhone, but I guess the question is the same on the Mac. What is your approach to debug the state of your application after it has been launched by its URL scheme?

• Multiple repositories, single setup

  - by graham.reeds

  If I use multiple repositories, all located under a single root folder, how can I set it up so that they will use a single master svnconf/passwd file for setup but still allow me to customize each if the need arises? This is on windows but I guess the process would be similar on other systems. Update: I am using svnserve as a service.

• What exactly are those data types int 16, int 32 and int 64 on the iPhone, in Core Data?

  - by mystify

  The Xcode data modeler shows me those three different int data types. When I would write code, which data types do these really correspond to on the iPhone? Are they all simply NSInteger, wrapped in an NSNumber? As far as I see it, NSNumber only differentiates between int an NSInteger... so I guess those three end up beeing pretty much the same?

• Why is there no middleware in Erlang?

  - by Zubair

  I asked a question earlier about ESBs written in Erlang or Java, and there didn't seem to be anything in Erlang, and only products in Java. http://stackoverflow.com/questions/2453641/what-would-be-the-best-language-in-which-to-write-an-esb/2453683#2453683 I guess I find it difficult to understand why a language like Erlang has no such middleware products, especially seeing as it should be ideally suited to the job.

• How to take advantage of subprocess within Django? - Django

  - by RadiantHex

  Hi folks, I'm currently using os.popen() but have been recommended to use subprocess.popen() instead. Any ideas on how I can integrate this? It would be cool and fun to have a Python shell accessible on a Django app. But I reckon that it might be a bit complex to implement. I guess I would have to retrieve the subprocess, as a new request comes in. Any ideas?

• Any Javascript optimization benchmarks?

  - by int3

  I watched Nicholas Zakas' talk, Speed up your Javascript, with some interest. I liked how he benchmarked the various performance improvements created by various optimization techniques, e.g. reducing calls to deeply nested objects, changing loops to count down instead of up, etc. I would like to run these benchmarks myself though, to see exactly how our current browsers are faring. I guess it wouldn't be too difficult to cook up some timed loops, but I'd like to know if there are any existing implementations out there.

• Drupal 6: best way to upgrade jQuery ?

  - by Patrick

  Hi! I want to upgrade jQuery inside my drupal installation. At the moment I have jQuery 1.2.6 and I would like to upgrade it to jQuery 1.4 I guess some Drupal modules still depends on the old jQuery version. I've tried jquery_update module to upgrade jQuery, but it didn't work. It asked to replace the original Drupal files in the "misc" folder with the new ones, but it didn't work. Anyway, I was wondering if there is a better method instead of using another module thanks

• I need a dictionary-like mapping between characters and other kinds of objects. Which class would be

  - by nullPointerException

  This is in Squeak/Pharo. If I want to have a mapping between Character objects like $a and $b to other kinds of objects, and want to look up those other objects based on the Character, what is the best class to use? Dictionary is an obvious choice, but seems wasteful to be hashing character objects which are basically already numbers. I guess what I want is a kind of array where the character value (number) is used as an index/offset, but I am not sure if this is possible with Unicode.

  - by Patito

  Hi, I'm running Appverifier in an application. When it detects a memory leaks the logs saids "Address of the leaked allocation. Run !heap -p -a to get additional information about the allocation." I guess that's when you are running in Windbg, is there any way to access the allocation stack trace from inside Visual Studio ?

But there's a stuff. Just in an anonymous category. Let me guess: Impossible. Other solutions?

• Updating UILabel and UIButton immediately

  - by paul simmons

  Hi, In a project, I change a UILabel's text with setText, a UIButton's color and after that do a time consuming calculation, followed by an animation. However, the text's and color's change is reflected after the calculation is executed (and before the animation begins) however I want to reflect the changes immediately before calculation (as you guess it is a waiting text) How can I achieve this?

• On Update: Auto Update Date/Time Field

  - by Abs

  Hello all, Is there an equivalent of MySQLs on update field for SQL server? With both DEFAULT CURRENT_TIMESTAMP and ON UPDATE CURRENT_TIMESTAMP clauses, the column has the current timestamp for its default value, and is automatically updated. What I am looking for is to have a date/time field and every time I update a record it updates the field with the date/time it was updated automatically? If it doesn't exist, I guess I'll have to go manual. Thanks all

• What UIKit elements can be used to replicate the App Store/iTunes Store paged grid?

  - by user350523

  I'm new to Cocoa Touch, so this might be pretty easy, but I can't seem to figure out what UIKit elements were used to create a grid like this? Is this simply a UITableView with a pagination controller? If so, how'd they style it like this? Thanks! PS: I'm not allowed to post images yet, i guess. hopefully the link works... http://img576.imageshack.us/img576/8523/screenshot20100525at941.png

• Graph generation on iPhone

  - by Parrots

  Anyone have experience with drawing graphs on the iPhone? Looks like GraphKit isn't an option, so it's up to the programmer to either write his own library (using OpenGL, I guess), or an existing library. I can't seem to find any libraries that are confirmed to work on the iPhone. If you've written your own how did you go about it (opengl, quartz, etc), or if you used a library which one?
