• Reason for monolithic data files

  - by Ali Lown

  Primarily this seems to be a technique used by games, where they have all the sounds in one file, textures in another etc. With these files commonly reaching the GB size. What is the reason behind doing this over maintaining it all in subdirectories as small files - one per texture which many small games use this, with the monolithic system being favoured by larger companies? Is there some file system overhead with lots of small files? Are they trying to protect their property - although most just seem to be a compressed file with a new extension?

• How to use locks/synchronization here

  - by MasterGberry

  I have this code block here and i need to make sure the rankedPlayersWaitingForMatch is synchronized between threads properly. I was going to use synchronize but that i don't think will work here because of the variable being used in the if statement. I read online about final Lock lock = new ReentrantLock(); but I am a bit confused on how to use it in this case properly with the try/finally block. Can I get a quick example? Thanks // start synchronization if (rankedPlayersWaitingForMatch.get(rankedType).size() >= 2) { Player player1 = rankedPlayersWaitingForMatch.get(rankedType).remove(); Player player2 = rankedPlayersWaitingForMatch.get(rankedType).remove(); // end synchronization // ... I don't want this all to be synchronized, just after the first 2 remove() } else { // end synchronization // ... }

• Operator() as a subscript (C++)

  - by Ivan Gromov

  I use operator() as a subscript operator this way: double CVector::operator() (int i) const { if (i >= 0 && i < this->size) return this->data[i]; else return 0; } double& CVector::operator() (int i) { return (this->data[i]); } It works when I get values, but I get an error when I try to write assign a value using a(i) = 1; UPD: Error text: Unhandled exception at 0x651cf54a (msvcr100d.dll) in CG.exe: 0xC0000005: Access violation reading location 0xccccccc0.

• Time Complexities of recursive algorithms

  - by Peter

  Whenever I see a recursive solution, or I write recursive code for a problem, it is really difficult for me to figure out the time complexity, in most of the cases I just say its exponential? How is it exponential actually? How people say it is 2^n, when it is n!, when it is n^n or n^k. I have some questions in mind, let say find all permutations of a string (O(n!)) find all sequences which sum up to k in an array (exponential, how exactly do I calculate). Find all subsets of size k whose sum is 0 (will k come somewhere in complexity , it should come right?). Can any1 help me how to calculate the exact complexity of such questions, I am able to wrote code for them , but its hard understanding the exact time complexity.

• Internet explore is unresponsive while loading a large page

  - by kdhamane

  We have a html page being rendered in the browser (IE) that causes the browser to hang. The page is generated through server side script (ASP.NET and viewstate is disabled). The page while loading takes a long time (its not a b\w issue since we can reproduce it on local machine) and sometimes results in script unresponsive error. On debugging the issue we found that the html size on the client side is 4.73 MB. There's also a lot of DOM traversal (using JQuery) after document is ready (jquery-document.ready). After loading as well, the page simply hangs on any user interaction (scroll, mouseover) etc. A CPU usage spike (25-50% usage) is seen during loading and on any user interaction

• Sorting by key > 10 integer sequences. with thrust

  - by smilingbuddha

  I want to perform a sort_by_key where I have a single key-sequence and multiple value sequences. One usually performs this with sort_by_key( key, key + N, make_zip_iterator( make_tuple(x1 , x2 , ...) ) ) However I want to perform a sort with 10 sequences each of length N. Thrust does not support tuples of size = 10. So is there a way around this ? Of course one can keep a separate copy of the key vector and perform sorts on bunches of 10 sequences. But I would like to do everything in a single call.

• Can I find out if the java program was launched using java or javaw

  - by saugata

  This is related to an earlier question by a different user How to detect that code is running inside eclipse IDE I noticed that eclipse always launches programs with javaw rather than java. (This does not imply a program launched with javaw was launched from eclipse). I can find the arguments passed using RuntimeMXBean RuntimemxBean = ManagementFactory.getRuntimeMXBean(); List<String> lst=RuntimemxBean.getInputArguments(); for(int i=0;i<lst.size();i++) System.out.println(lst.get(i)); But this does not tell me whether it was launched using java or javaw. Is there any way to find it out? Another related question is why does eclipse use javaw to launch programs?

• Should we use a CSS frame work ? Are they worth it ?

  - by Gaurav M

  CSS frameworks have nice styles inbuilt and ask you to focuses on the grids but still there is a bit of dependency and lack of freedom it provide.. If I need to generate a webpage by looking on a PSD based mockup screen ..either i will use the classes provided by the framework but if that actual measurements does not exist I need to again specify my own rules that will add upto my CSS filesize and if performance is a constraint as always it is...you need not a big size file..though its in kb but every drop counts. Any comments and suggestions to use the framework in a best possible way.

• IE6 extra padding on bottom

  - by Gian Basagre

  I have a div tag styled through CSS. I set the padding to 10px (padding:10px), it works just as I wanted in Firefox and IE7, but in IE6 it adds additional padding at the bottom (about 2-3px I think). Anyone has idea about what's happening here? [update] I just noticed this, the div tag I'm talking about has a background-image. When I removed the background-image, the extra padding on the bottom disappears. Any ideas? [another update, code sample] Here's the CSS applied to my div tag: .user-info{ margin-top: 20px; margin-right: 20px; padding: 10px; background-image: url("../img/user_panel_bg.png"); float:right; border: 1px #AAAAAA solid; font-size:12px; }

• C# Virtual Mode List View Click 1 Selects More Than One Items

  - by Samir

  I have a list view with virtual mode set to true and other things. It doing ok. But 1) Say there are 25 items and 15 of them are visible, that is to see the rest of 10 items need to scroll down. 2) Before scrolling swap two items, say myItems[0], it must be visible & myItems[20], it must be not visible scroll required. 3) Now select the first item, it was swapped, you now have two items selected, both 0 indexed and 20 indexed ones. When after swap, those two list view items are of same Position and same Bounds. But before 20-indexed item's Position was (-1, -1) and Bounds was (0,0,0,0). How come 0-indexed item didn't change its position & size? How to solve this ?

• Potential problems porting to different architectures

  - by Brendan Long

  I'm writing a Linux program that currently compiles and works fine on x86 and x86_64, and now I'm wondering if there's anything special I'll need to do to make it work on other architectures. What I've heard is that for cross platform code I should: Don't assume anything about the size of a pointer, int or size_t Don't make assumptions about byte order (I don't do any bit shifting -- I assume gcc will optimize my power of two multiplication/division for me) Don't use assembly blocks (obvious) Make sure your libraries work (I'm using SQLite, libcurl and Boost, which all seem pretty cross-platform) Is there anything else I need to worry about? I'm not currently targeting any other architectures, but I expect to support ARM at some point, and I figure I might as well make it work on any architecture if I can. Also, regarding my second point about byte order, do I need to do anything special with text input? I read files with getline(), so it seems like that should be done automatically as well.

• POST data disapearing on large file upload

  - by DfKimera

  I'm having issues with a file uploading utility in my PHP application. When sending large files (9MB+) over the form, I get a very odd behaviour: the POST data I've included in the form dissapears, including the file information. I've already increased all PHP limits I could (time limit, max input time, post max size, memory limit and upload max filesize) and I still can't get the proper behaviour. I've tried replacing the regular HTTP forms with a Flash-based solution (SWFUpload, www.swfupload.org), still the same behaviour. I've tried multiple files of similar sizes and its definitely not a particular file issue. I've debugged the POST vars sent using Firebug, and the correct variables are still there in the header, together with the file. What could be going on here?

• VB.NET Window Screen Capture (ALT+PRINTSCREEN)

  - by Steve Thomas

  Hi, I found that code somewhere and I find it quite useful but I would like to find a way to make it work so it capture only the given window target. Maybe with a processID or Window Name. Even if that window is not active. I do not want to make that window active but want to get a screen capture like if I was doing Alt+PrintScreen on it. Here is the code that works for full Screen Capture Private bmpScreenShot As Bitmap Private gfxScreenshot As Graphics bmpScreenShot = New Bitmap(Screen.PrimaryScreen.Bounds.Width, Screen.PrimaryScreen.Bounds.Height, PixelFormat.Format32bppArgb) gfxScreenshot = Graphics.FromImage(bmpScreenShot) gfxScreenshot.CopyFromScreen(Screen.PrimaryScreen.Bounds.X, Screen.PrimaryScreen.Bounds.Y, 0, 0, Screen.PrimaryScreen.Bounds.Size, CopyPixelOperation.SourceCopy) bmpScreenShot.Save(fileName, ImageFormat.Png) I use the Visual Basic 2008 Express Thank you in advance!

• Font not correctly displaying in Internet Explorer using the css property @font-face

  I'm trying to render a font using the css property @font-face , in Firefox, Chrome and Opera it works fine, but within Internet Explorer is just does not want to display correctly, and reverts back to another standard font. My code looks as follows @font-face { font-family: "swatch"; src: url("../../fonts/swatch.eot"); /* IE */ src: url("../../fonts/swatch.ttf") format("truetype"); } .header_text1{ font-family: "swatch"; font-size: 78px; text-align:center; color: #ffffff; padding-top: 50px; } Am I doing something wrong here?

• Weblogic Error - Method not supported : Statement.cancel

  - by manetic

  I am running an application on Weblogic 9.2 MP3, currently having problem with connection pool. ERROR - UserBean retrieving user record. weblogic.jdbc.extensions.PoolLimitSQLException: weblogic.common.resourcepool.ResourceLimitException: No resources currently available in pool MyApp Data Source to allocate to applications, please increase the size of the pool and retry.. I also kept getting below error message, saying "Method not supported : Statement.cancel()" which I think it is the cause to the error above. <Error> <JDBC> <BEA-001131> <Received an exception when closing a cached statement for the pool "MyApp Data Source": java.sql.SQLException: Method not supported : Statement.cancel()..> I went through the app source code, this method didn't seem to be used by the app at all. Just though it might be something to do with weblogic itself. Anyone have any idea to fix this error?

• can't list files in a directory

  - by Anthony

  I'm using CF 7 and this code is not returning any files: <cfset fileLocation = "\\server\uploader\pass-fail"> <cfdirectory action = "list" directory = fileLocation name = "pass_fail_files" > <cfdump var="#pass_fail_files#" expand="yes" label="files in pass-fail" > <cfoutput>#pass_fail_files.name#</cfoutput> <cfoutput>#pass_fail_files.directory#</cfoutput> <cfoutput>#pass_fail_files.size#</cfoutput> <cfoutput>#pass_fail_files.type#</cfoutput> <cfoutput>#pass_fail_files.dateLastModified#</cfoutput> <cfoutput>#pass_fail_files.attributes#</cfoutput> <cfoutput>#pass_fail_files.mode# </cfoutput> I have checked to make sure that the directory indeed has several text files. But when I run the code, all I get is: What am I doing wrong?

• Heavy use of templates for mobile platforms

  - by Chris P. Bacon

  I've been flicking through the book Modern C++ Design by Andrei Alexandrescu and it seems interesting stuff. However it makes very extensive use of templates and I would like to find out if this should be avoided if using C++ for mobile platform development (Brew MP, WebOS, iOS etc.) due to size considerations. In Symbian OS C++ the standard use of templates is discouraged, the Symbian OS itself uses them but using an idiom known as thin templates where the underlying implementation is done in a C style using void* pointers with a thin template layered on top of this to achieve type safety. The reason they use this idiom as opposed to regular use of templates is specifically to avoid code bloating. So what are opinions (or facts) on the use of templates when developing applications for mobile platforms.

• Is it possible to shrink rt.jar with ProGuard?

  - by PatlaDJ

  Is there a procedure by which you can optimize/shrink/select/obfuscate only 'used by your app' classes/methods/fields from rt.jar provided by Sun by using some optimization software like ProGuard (or maybe other?). Then you would actually be able to minimize the download size of your application considerably and make it much more secure ? Right? Related questions: Do you know if Sun's "jigsaw project" which is waited to come out, is intended to automatically handle this particular issue? Did somebody manage yet to form an opinion about Avian java alternative? Please share it here. Thank you.

• mod_perl memory leak

  - by marghi

  Hello, I recently discovered that one of our sites has a memory leak in it, it's very strange because it happened all of the sudden. I've used GTop to measure the memory size per process and it tells me that the real value is somewhere around 65 MB (on the server) per request and and additional 5 MB shared. I tried preloading the modules in the startup.pl file a indicated in the performance tuning article for mod_perl. Nothing happened if fact the shared memory decreased down to 3.7 MB, in this situation I thought that my application is leaking memory do before any line of code got executed I measured the memory just to find out that the total value is in fact 64 MB, my questions are: Is there a default preallocation of memory for each process? Is there a configuration issue? Is mod_perl leaking memory ? Thank you very much.

• Base64 encoding in PHP not working for '&' and '#' ?

  - by Angad

  My knowledge about base64 is pretty limited. I am using it as an alternative to string escaping in a content management system, for I had been warned about how weaknesses have been found in mysql_real_escape_string(); and quite sheepishly so, as I am aware of how it buffs text size up. PHP seems to truncate everything after an instance of # or & in the string; please help me out of this one. Also, comment on whether using base64 to maintain the 'trueness' of post content in the CMS is just plain retarded, or a wise move. Thanks for your time :)

• Submtting data using $.ajax and retrieving values from $_POST array

I've tried to stringify the data being sent, and also tried to decode the $_POST array but it expects a string.....

• Reading in 4 bytes at a time

  - by alphomega

  I have a big file full of integers that I'm loading in. I've just started using C++, and I'm trying out the filestream stuff. From everything I've read, it appears I can only read in bytes, So I've had to set up a char array, and then cast it as a int pointer. Is there a way I can read in 4 bytes at a time, and eliminate the need for the char array? const int HRSIZE = 129951336; //The size of the table char bhr[HRSIZE]; //The table int *dwhr; int main() { ifstream fstr; /* load the handranks.dat file */ std::cout << "Loading table.dat...\n"; fstr.open("table.dat"); fstr.read(bhr, HRSIZE); fstr.close(); dwhr = (int *) bhr; }

• Efficient implementation of natural logarithm (ln) and exponentiation

  - by Donotalo

  Basically, I'm looking for implementation of log() and exp() functions provided in C library <math.h>. I'm working with 8 bit microcontrollers (OKI 411 and 431). I need to calculate Mean Kinetic Temperature. The requirement is that we should be able to calculate MKT as fast as possible and with as little code memory as possible. The compiler comes with log() and exp() functions in <math.h>. But calling either function and linking with the library causes the code size to increase by 5 Kilobytes, which will not fit in one of the micro we work with (OKI 411), because our code already consumed ~12K of available ~15K code memory. The implementation I'm looking for should not use any other C library functions (like pow(), sqrt() etc). This is because all library functions are packed in one library and even if one function is called, the linker will bring whole 5K library to code memory.
