  • Can I assign array size using NSMutableArray?

    - by Tattat
    I used to be a Java Programmer, which the array need to declare the very first time, like this: int[] anArray; // declares an array of integers anArray = new int[10]; // allocates memory for 10 integers I don't know whether the Objective C , NSMutableArray also give me this ability or not. Actually, I want to make a 10*10 array. thz in advance.

  • What the best multi-thread application debugger for C++ apps.

    - by Coredumped
    I'm looking for a good multi-thread-aware debugger, capable of showing performance charts of application threads on Linux, don't know if such a thing exists, perhaps as a Eclipse plugin. The idea would be to track per thread memory allocation a CPU usage as well as being able to interrupt a thread and examine its stack trace, local vars, etc. It does not have to be an eclipse plugin or a free tool, do any of you have heard of something similar?

  • new Integer vs valueOf

    - by LB
    Hi, I was using Sonar to make my code cleaner, and it pointed that I'm using new Integer(1) instead of Integer.valueOf(1). Because it seems that valueOf does not instantiate a new object so is more memory-friendly. How can valueOf not instantiate a new object ? How does it work ? Is this true for all integers ? thanks.

  • Unable to debug St9bad_alloc error. Tried reducing the size of the data structure, error still persists

    - by timtowtdi
    I get a St9bad_alloc error which I'm unable to debug. I tried reducing the size of the data structure to eliminate the possibility that I might be running out of memory but that doesn't seem to be the case. These are the relevant files:- gdb backtrace: http://pastebin.com/5hFhHXnL TraceCache.cc: http://pastebin.com/j8vK812j I can't understand how, in the backtrace it jumps from TraceCache.cc:55 to TraceCache.cc:34 whereas in my code I can't see any such path. Please let me know in case any other information is required. Thanks

  • Possible reasons and resolutions for time out

    - by ming yeow
    I cannot SSH into my instance - Operation timed out. What could be the reasons why, and what can I do to resolve it? Rebooting normally takes a long time to take effect, and might just makes things worst UPDATE: It is not about permissions - i can log in normally just fine. I suspect it might be because of memory issues

  • if with multiple conditions, order of execution

    - by markus
    Hi, In an if statement with multiple conditions is second executed if the outcome is clear after checking the first condition? example: if(i>0 && array[i]==0){ } If I swap the conditions a seg fault may occur for negative values of i but this way the memory debugger doesn't find a problem. Can I be sure that this works always or do have have to use nested if statements?

  • What does "performant" software actually mean?

    - by Roddy
    I see it used a lot, but haven't seen a definition that makes complete sense. Wiktionary says "characterized by an adequate or excellent level of performance or efficiency", which isn't much help. Initially I though performant just meant "fast", but others seem to think it's also about stability, code quality, memory use/footprint, or some combination of all those. I think this is a "real" question - but if enough people reckon this is a subjective question, that's an answer in itself.

  • How can I close a JFrame by click on a button?

    - by Roman
    I would like to have a button in my window such that if I click it (button) the window is closed. I found out that I can close a window in the following way: referenceToTheFrame.hide(); //hides the frame from view refToTheFrame.dispose(); //disposes the frame from memory But if I do this way, compiler complains: Note: myProgram.java uses or overrides a deprecated API Note: Recompile with -Xlint:deprication for details. Do I do something unsafe?

  • Delphi: Which are the downsides of having unused units listed in the uses clause?

    - by user193655
    I use cnPack Uses cleaner, but in general which are the downsides of having useless units? I know some of them: 1) of course if the unit is never used across the full project there will be useless resource consuption 2) the code insight will give useless results 3) the code insight will be slower But imagine a simple case: I have a project with 2 forms, I use StrUtils in one of them but I declared StrUtils in both of them... Is there any downside in temrs of memory consumption in this case or not?

  • Appverifier and Visual Studio for leak detection

    - 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 ?

  • GC generation 3 appearing in windbg

    - by Johnv2020
    I've a dump file of a process I'm running (trying to find a memory leak) One thing I've noticed is that when I dump the bigger objects via !do windbg tells me that they are GC generation 3 ?? All of these are byte arrays so when I look at all the byte arrays in the dump I can see GC generations 0, 1, 2 & 3. Could someone explain whats going on here as I thought there was only 3 generations of GC.

  • How early can I call kalloc in an arm linux kernel?

    - by Isaac Sutherland
    I would like to dynamically allocate memory from the machine_init function in my arm linux kernel. Calling kalloc can result in a complete failure of the system to boot. My debugging tools are very limited so I can't give much more information regarding the failure. Simply put, is it legal to call kalloc from a machine_init function in arm linux, and, if not, is there an alternative?

  • Is there any way static block is executed more than once? if so then how?

    - by learner
    My Understanding Static block is executed during class loading, If a class is already loaded then there is no way to load the class other than class reloading Doubt/Question 1) Is there any time JVM reloads the class? My Understanding In Class Loading JVM loads source of the Java file, so it can not keep all thousands files source is a memory, it should discard the rarely used code and reload again when it is necessary and during reload JVM is not initializing static variables and locks again(may be using some tracking mechanism) Doubt/Question 2) If my above understanding is incorrect then please correct me

  • Destructors in C++

    - by user265260
    does the Destructor deallocate memory assigned to the object which it belongs to or is it just called so that it can perform some last minute housekeeping before the object os deallocated by the compiler?

  • Special folders & functionality in Windows [closed]

    - by lloydsparkes
    I am using the new Virtual PC Beta on Windows 7 and I saw: The virtual machines have a special directory, but once you are in it, the VMs are shown. How can I do the same thing, with custom headings ("Machine status", "Memory", etc.) and custom toolbar buttons ("Create virtual machine")? I can't seem to find any documentation for this.

  • Should I be backing up a webapp's data to another host continuously ?

    - by user196289
    I have webapp in development. I need to plan for what happens if the host goes down. I will lose some very recent session status (which I can live with) and everything else should be persistently stored in the database. If I am starting up again after an outage, can I expect a good host to reconstruct the database to within minutes of where I was up to ? Or seconds ? Or should I build in a background process to continually mirror the database elsewhere ? What is normal / sensible ? Obviously a good host will have RAID and other redundancy so the likelihood of total loss should be low, and if they have periodic backups I should lose only very recent stuff but this is presumably likely to be designed with almost static web content in mind, and my site is transactional with new data being filed continuously (with a customer expectation that I don't ever lose it). Any suggestions / advice ? Are there off the shelf frameworks for doing this ? (I'm primarily working in Java) And should I just plan to save the data or should I plan to have an alternative usable host implementation ready to launch in case the host doesn't come back up in a suitable timeframe ?

  • How do games move around objects (in general) (OGL)

    - by user146780
    I'm sure there's not just 1 answer to this but, do game engines actually change the vectors in memory, or use gltransformations? Because pushing and popping the matrix all the time seems inefficient, but if you keep modifying the verticies you cant make use of display lists. So I'm wondering how it's done in general. Thanks
