I have the following function: void CGlEngineFunctions::GetBezierOpposite( const POINTFLOAT &a,const POINTFLOAT ¢er, POINTFLOAT &b, float blength ) { POINTFLOAT v; v.x = a.x - center.x; v.y = a.y - center.y; float alength = GetDistance(a,center); if(blength == 0) { blength = alength; } fl...
I use MPMoviePlayerViewController to make a moviePlayer. But, when I click the "done" button, or cancel the player, the memory used always increases. Why?? ...
I am using R 2.11.1 and XML package 3.1-0, and I was going through an example from R2GoogleMaps when I encountered a segfault error. #library(RJSONIO) library(R2GoogleMaps) library(XML) #library(RCurl) load("b.rda") # find in the sampleDocs folder in source file of R2GoogleMaps center = c(mean(range(b$lat)), mean(range(b$long))) code ...
Hi, in several example codes one can find this static NSNumberFormatter *numberFormatter = nil; if (numberFormatter == nil) { numberFormatter = [[NSNumberFormatter alloc] init]; [numberFormatter setNumberStyle:NSNumberFormatterDecimalStyle]; [numberFormatter setMaximumFractionDigits:6]; } Isn't that code producing memory ...
Hi Forum I have an app that stacks quite a nice amount of views on top of each other. At some point I receive a Memory warning level2 (which is kind of expected). The thing is, when I run Instruments, I don't have any memory leaks and the app takes up something like 9-10MBs... which is not that much, I'd say? Question is: how much me...
Hello all, I have the function below which I call very frequently in a loop. I waited 5 minutes as the memory climbed up from 1MB to 156MB. Should't PHP's garabage collector turn up and reduce this at some point?! Is it because I have set memory limit at 256MB? At echo point 2,3,4 its pretty constant memory usage. It goes down my hal...
Hello, I am using WebClient,DownloadString("http://example.com/string.txt"); When I call it the memory jumps up, but never goes down again, and since I need 2-3 different strings downloaded from the web the memory jumps up quite much. I am new to C# and still learning, but is there anyway to clear the memory after I have downloaded the...
Hello, I'm getting a weird leak in my NSXMLParser after it's done and released from memory. It comes up with NSMapTable alloc leak. Here's my stack: 0 libSystem.B.dylib calloc 1 libobjc.A.dylib _internal_class_createInstanceFromZone 2 libobjc.A.dylib class_createInstance 3 Foundation NSAllocateObject 4 Foundation +[NSM...
I need to use JDOM to generate XML files, which could be pretty big. I'm wondering how much additional memory space JDOM needs other than the data, mainly strings, that is already in the memory. I wrote a simple program to test and it turned out that the overhead is about twice as much as the XML content. Does anybody know why JDOM need...
I'm using SQLBULKCOPY to copy some data-tables into a database table, however, because the size of the files I'm copying run sometimes in excess of 600mb, I keep running out of memory. I'm hoping to get some advice about managing the table size before I commit it to the database so I can free up some memory to continue writing. Here ar...
We have a C# service that has started failing in very odd ways around thread handles. Specifically calls to EventWaitHandle.Reset, ReaderWriterLock calls, and other similar threading calls are randomly blowing up with Invalid Handle errors deep in the stack. These are calls that are definately supposed to work. Could this be a sign of me...
So I have several viewControllers, each creates images using "imageWithContentsOfFile" in order to conserve memory and then sets objects to nil and releases them in the dealloc method. There are no memory leaks. The problem is memory still builds up when switching views. So for example I'll be in view1 and it'll be using 8MB of memory an...
After implementing some of the solutions in my previous question, I've come up with the following solution: reader = open('C://text.txt') writer = open('C://nona.txt', 'w') counter = 1 names, nums = [], [] row = reader.read().split(' ') x = len(row)/2 for (a, b) in [(c, d) for c, d in zip(row[:x], row[x:]) if d!='na']: prin...
What can we do more with qubits than normal bits, and how do they work? I read about them some time ago, and it appears that qubits can store not just 0 or 1, but also 0 and 1 at the same time. I don't really understand how they work. Can someone please explain this to me? What are their pros and cons, and what impact will they have on ...

I work on a legacy system that has a VB6 app that needs to call Java code. The solution we use is to have the VB app call a C++ dll that uses JNI to call the Java code. A bit funky, but it's actually worked pretty well. However, I'm moving to a new dev box, and I've just run into a serious problem with this. The built VB app works fi...
I have virtual memory size set to 756 MB on windows xp. but when reading on msdn it says virtual memory for each process on 32 bit OS is 4 GB by default. how it is different from the size of virtual memory that i set? **Memory** **range** **Usage** Low 2GB (0x00000000 through 0x7FFFFFFF) Used by the process.

I've been working on a graphing/data processing application (you can see a screenshot here) using Clojure (though, oftentimes, it feels like I'm using more Java than Clojure), and have started testing my application with bigger datasets. I have no problem with around 100k points, but when I start getting higher than that, I run into heap...
