• Rails, ActiveRecord, how to find foreign rows that are NOT there?

  - by randombits

  The title is a bit difficult to put together for this question. Say I have two models, Foo and Bar. Foo has many Bar's. Bar belongs to one Foo. How do I use Foo.find to find all of the Foos that currently have zero Bars? In SQL this would translate into something like: SELECT * from foo where id NOT IN (select foo_id from bar);

• Port Android App to Desktop?

  - by CodeJustin.com

  I'm just wondering if it would be possible (and legal) to port an Android app to desktop? I'm creating an android game that would work well on PC too (even with the cellphone like layout) and was thinking that maybe I could 'embed' an android emulator with an installer or would that process be a bit hard for a novice Java coder?

• YUI vs jQuery, for css style layouts

  - by tony

  Hi Complete novice question. I've used jQuery a bit, YUI not at all and know very little about it. I work on a website thats IE specific, we're now looking at making it cross browser. jQuery seems great at hiding the differences between browsers from a javascript point of view. However in terms of css layout is it YUI that I should really be looking at? thanks

• Amazon EC2 pricing question

  - by Industrial

  Hi everyone, I took my first step today on working with cloud servers and chosed Amazon EC2 for this project. Since I am a bit of a newcomer on this, I didn't fully understand their pricing: What happens when a instance is idling with no connections being made. Does it still cost us money? It would be sad to have instances idling and costing us money when we do not use them... Thanks a lot!

• How to find an audio file's length (in seconds)

  - by mIL3S

  Hi all! (Objective C) Just using simple AudioServicesPlaySystemSoundID and its counterparts, but I can't find in the documentation if there is already a way to find the length of an audio file. I know there is AudioServicesGetPropertyInfo, but that seems to return a byte-buffer - do audio files embed their length in themselves and I can just extract it with this? Or is there perhaps a formula based on bit-rate * fileSize to convert to length-of-time? mIL3S www.milkdrinkingcow.com

• How to construct a c++ fstream from a POSIX file descriptor?

  - by BD at Rivenhill

  I'm basically looking for a C++ version of fdopen(). I did a bit of research on this and it is one of those things that seems like it should be easy, but turns out to be very complicated. Am I missing something in this belief (i.e. it really is easy)? If not, is there a good library out there somewhere to handle this?

• which loop is faster?

  - by Mansuro

  I have this loop for (it= someCollection.iterator; it.hasNext(); ) { //some code here } I changed it to: for (it= someCollection.iterator;; ) { if (!it.hasNext()) break; //some code here } The second code ran a little bit faster in unit tests in junit on eclipse. Is the second loop faster? I'm asking because the times given by Junit are not too exact, but they give an approximate value

  Hi, what I want to do is PHP to look at the url and just grab the name of the file, without me needing to enter a path or anything (which would be dynamic anyway). E.G. http://google.com/info/hello.php, I want to get the 'hello' bit. Help? Thanks.

• Is flash's geturl(...) spiderable by google?

  - by tom

  If I made a homepage with an embedded .swf which had buttons that linked to other html pages on my website using the getUrl() function, would those links be spiderable by google? Or should I also put in text links outside of the .swf (which would ruin the design a bit)? I know a lot of people will argue I shouldn't have flash as the main content on the homepage (and their comments are appreciated), but bear in mind, that's not my question.

• How do I bring a processes window to the foreground on X Windows? (C++)

  - by Lorenz03Tx

  I have the PID for the process (and the name), I want to bring it to the front on linux (ubuntu). On mac I would simply do SetFrontProcess(pid), on windows I'd enumerate the windows pick out the one I wanted and call SetWindowPos(hwnd, HWND_TOPMOST, 0, 0, 0, 0, SWP_NOMOVE | SWP_NOSIZE); but I'm at a loss of what to do on linux. I've looked at X Lib a bit, but most/all of those functions seem to operate on windows inside your process. Thanks in advanced.

• Drupal 7: Rename files on upload (via filefield)

  - by Eugene

  Looking for a way to rename files that are uploaded by users through a filefield. For example, rename user profile photos using uniqid. I found a good solution for D6 here: http://www.wesjones.net/home/2011/03/drupal-6-how-to-change-filename-on-upload but can't find anything for D7. Another option is to use File (Field) Paths, but (1) the module causes warnings on my setup and (2) seems to be a bit of an overkill to install a general module for a very specific purpose.

  Is there a way to check in VS how much time did I spend on particular project? It's just I feel that I'm not working fast enough and seeing the actual time I spent would probably kick me in my ass and maybe I would speed up a bit. Thanks.

• Are there any "gotchas" to watch for in using a Class (object) within itself?

  - by Clay Nichols

  I've got a Registry class and there are a few Registry values that I want to access from within that Registry class. (There is a bit of a calculation with these values so I thought I'd just put all that code right in the Registry Class itself). So we might have something within our RegistryRoutine.cls like: Function GetMyValue() as integer Dim R as new RegistryRoutine <calculations> GetMyValue=R.GetRegisetryValue (HKEY, key, value, etc.) End Function
