• How to free static member variable in C++?

  - by user299831

  Can anybody explain how to free memory of a static member Variable? In my understanding it can only be freed if all the instances of the class are destroyed. I am a little bit helpless at this point... Some Code to explain it: class ball { private: static SDL_Surface *ball_image; }; //FIXME: how to free static Variable? SDL_Surface* ball::ball_image = SDL_LoadBMP("ball.bmp");

• Need a TV/Movie API with associated trailers

  - by Paul

  Looking for a movie/TV API that offers previews (trailers), via widgets or links, as well. I know IMDB has an API, but it only has metadata. Internet Video Archive also has an API, but, well, lets just say they seem a bit incompetent. I could use YouTube, but I'd get a lot of cruft and unofficial results. Anyone else have any ideas?

• Determining the word width in C

  - by das_weezul

  Hi! I'm learning C right now and so I'm fiddling about with pointers. Is there a way to determine the word width of the CPU in C because I'm writing a small program which prints it's own stack (Because I'm curious how it is structured), so that information would come in handy. Right now I'm using an int pointer, as an integer is 4 Bytes wide and I'm using a 32-bit Intel Atom CPU. Thanks in advance, C gurus ;o)

  Having a bit of difficulty figuring out how to create a named_scope from this SQL query: select * from foo where id NOT IN (select foo_id from bar) AND foo.category = ? ORDER BY RAND() LIMIT 1; Category should be variable to change. What's the most efficient way the named_scope can be written for the problem above?

• Save from viewController?

  - by fuzzygoat

  I have a very small bit of data that I would like to archive from my apps view. My question is, its far easier to save this data from the viewController, but should I really be pushing it back into my model and saving it there? BTW: I also need to do a quick load of this data when the app starts up.

  I realise there aren't any official ones, but I was hoping I could grab an unofficial one from somewhere? I'm running 32-bit Windows XP on x86 hardware (Core 2 Duo).

• Maintaining property lists for xCode projects

  - by William Jockusch

  My project currently contains two largish property lists. One is currently 20KB; another is 8KB. So far, I have been maintaining them with xCode's property list editor. This is manageable but also a bit clunky. I am wondering if other people have better ways of doing this? So far, my lists consist of nested arrays of strings. The depth is not uniform.

• 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?

• How to adjust the distribution of values in a random data stream?

  - by BCS

  Given a infinite stream of random 0's and 1's that is from a biased (e.g. 1's are more common than 0's by a know factor) but otherwise ideal random number generator, I want to convert it into a (shorter) infinite stream that is just as ideal but also unbiased. Looking up the definition of entropy finds this graph showing how many bits of output I should, in theory, be able to get from each bit of input. The question: Is there any practical way to actually implement a converter that is nearly ideally efficient?

• How to make a simple Wine-based installer for Windows application

  - by zarawesome

  My Windows application runs under Wine, but the installation is a bit of a headache for laymen, and the wrappers I've seen online (PlayOnLinux, Wine Doors) require even more packages to be installed. Is there a way to make a package that will install Wine if the user needs it to be installed, install the application and shortcuts, all with minimal user hassle?

• a good Java guide

  - by Lo'oris

  Do you know a good guide for Java, such as "dive into python" for python? If I searched google I expect I would find tons of random guides, but trying them all until I found a good one could take ages... that's why I am asking: do you already know one in particular? one you KNOW is good? I already know C, PHP and a bit of Python, if that matters.

• Why is cakephp form input stored in $this->data and POST data stored in $this->params['form'] ?

  - by spudnik1979

  the cakephp rest tutorial says that post data should be in $this-data, but I am finding that it is not, but instead inside $this-params['form'] However, when using cakephp form helper in a view, the data is in $this-data. Am I correct to have to check both locations in my controller? It just seems a bit of a waste of extra code. Shouldnt the data appear in one place for whether it came from a rest rest requestor or Cakephp form post? ps im using cakephp 1.3

• kill a process in bash

  - by wyatt

  How do I kill a process which is running in bash - for example, suppose I open a file: $ gedit file.txt is there any way within the command prompt to close it? This example is fairly trivial, since I could just close the window, but it seems to come up a bit, particularly when I mistype commands. Also is there any way to escape an executable which is running? This probably has the same solution, but I thought I'd ask anyway. Thanks

• AddDays() not working within a while loop

  - by r0bb077

  Is there anything that stops the DateTime AddDays() method that doesn't run within a while loop. I have this simple bit of code; DateTime last_day = monthCalendar2.SelectionRange.End; DateTime first_day = new DateTime(year, month, day); //Insert dates into vector while (first_day != last_day) { dates.Add(first_day); first_day.AddDays(1); } I step through the program and first_day never changes, anyone know why?!

• Are there any good ORMs (preferably JPA implementations) that support SQLLite (on Android)?

  - by yamsha

  I found a post from a while ago that addresses a similar question but I think it's a bit outdated. I realize implementations of JPA tend to be more on the heavy/dense side, so if you know of any lightweight (non-JPA) ORMs I'll most certainly appreciate your input. I did see the answer about ActiveAndroid in the other post and am curious to know if anyone tried it out.

• Logger.setLevel() doesn't enable logging correctly

  - by ripper234

  Situation: I have this log4j logger: private static final Logger logger = Logger.getLogger(ThisClassName.class); And am trying to set it programatically through: Logger.getLogger(ThisClassName.class).setLevel(Level.DEBUG); Still, DEBUG level prints are swalloed (while INFO prints are printed successfully). Even this bit has no effect: Logger.getRootLogger().setLevel(Level.DEBUG); Calling logger.debug("foo") reaches Category.forcedLog() and ConsoleAppender.doAppend(), and then fails (quits) at: if(!isAsSevereAsThreshold(event.getLevel())) Any idea why this is happening?

• Resizing Grid Views On Window Resize

  I'm making a small Windows Forms application that contains a lot of grid views. I want all the grid views to resize with the window. I could make a function that detects window resize and then changes the size of each grid view but that feels a bit clunky. Is there not an easier/more intelligent way to do this

• Light Weight repalcement to GNOME for Ubuntu

  I am working on rolling a bit of my own version of linux for my real time car application. I plan to base it off of minimal ubuntu (only needsd 32 MB of memory). I am not the most skilled person with linux so not really sure how to assess components when adding them to my system. What I am looking for is a lightweight windows manager to replace gnome and it has to support the gtkmm library. Does anyone know of one?

• Doxygen with C# internal access modifier

  - by Mike Gates

  I am using Doxygen to generate some API docs for a C# project I am working on. I have quite a bit of "internal" functionality in this project and don't want Doxygen producing these signatures in the generated html it produces. I have tried enabling HIDE_FRIEND_COMPOUNDS but this still results in my internal classes being exposed in the generated documentation. Does anyone know how to do this?

• Simple way to print value of a register in x86 assembly.

  - by Bob

  I need to write a program in 8086 Assembly that receives data from the user, does some mathematical calculations and prints the answer on the screen, I have written all parts of the program and all work fine but I don't know how to print the number to the screen. At the end of all my calculation the answer is AX and it is treated as an unsigned 16 bit integer. How do I print the decimal (unsigned) value of the AX register?
