  • twisted .loseConnection does not immediately lose connection?

    - by Claudiu
    I have a server with a few clients connected to it. When CTRL+C is hit (that is, reactor starts shutting down), I want to close all my connections, wait until they are cleanly closed, and then stop. I do this by going through the connected clients' transports and calling .loseConnection(). On the ones that are connected locally, they immediately disconnect. However, on one that is connected through the internet, the connection is not immediately lost. Communication stops - and closing the client program no longer even tells the server that the connection has died, although it does before calling .loseConnection() - but the connection is not deemed 'lost' until a few minutes later after I send a few heartbeat requests from the server. I understand that if a connection dies, there's no way for the server to know unless it tries to send some data. But if I specifically ask for a connection to be closed, why does it not just close/disconnect immediately? Am I calling the wrong function?

  • GIT sharing configuration data

    - by user569980
    Hi, I just started using GIT for my versioning and I want to program some tools that work on top of it. Here is my question: Which information in the .git/config is shared to a remote repo? Is any? Is there a special way to push information to that repo? The reason I am asking is that I would like to add a "unique stamp" to the config of a repo. Also the remote repo and everybody pulling that project should have the stamp. Is that possible? If not, is there any other way to identify a repository? Having a .git folder, I want to decide whether this git repo is the same as a previously specified remote repo (the same means created by pulling the remote repo, changes are okay, of course).

  • Java ME Runnable object takes up memory although not made an instance yet

    - by user1646684
    I am facing a strange problem with memory in Java ME. here is a part of my code: int variable=1; while (true) { if (variable==2) { display = Display.getDisplay(this); MyCanvas mc = new MyCanvas(this); // MyCanvas is a runnable object mcT = new Thread(mc); // new thread for MyCanvas mc.repaint(); display.setCurrent(mc); mcT.start(); // run thread } if (variable==1) { // Do some other stuff } } The problem is that although still the variable is set to 1, so it does not come through the if (variable==2) condition the program consumes 300kB more memory than when I delete the code after condition if (variable==2). As far as I know the code should by executed and the objects shall be created only when I set variable to value 2. But it consumes the memory also when the code after condition "if (variable==2)" is not executed. Why does this happen?

  • Array as struct database?

    - by user2985179
    I have a struct that reads data from the user: typedef struct { int seconds; } Time; typedef struct { Time time; double distance; } Training; Training input; scanf("%d %lf", input.time.seconds, input.distance); This scanf will be looped and the user can input different data every time, I want to store this data in an array for later use. I THINK I want something like arr[0].seconds and arr[0].distance. I tried to store the entered data in an array but it didn't really work at all... Training data[10]; data[10].seconds = input.time.seconds; data[10].distance = input.distance; The data will wipe when the program closes and that's how I like it to be. So I want it to be stored in an array, no files or databases!

  • End marker for command line arguments

    - by rwallace
    I'm writing a program which takes filenames and options on the command line in the usual way, and also can be directed to read arguments from a file. I'm implementing the semi-standard -- to turn off special treatment of subsequent arguments, and # as comment marker. I also want to implement a marker for 'disregard all arguments from here on', i.e. an end marker. Is there a common/semi-standard way to indicate this? Or, what way would people find least surprising?

  • Access violation C++ (Deleting items in a vector)

    - by Gio Borje
    I'm trying to remove non-matching results from a memory scanner I'm writing in C++ as practice. When the memory is initially scanned, all results are stored into the _results vector. Later, the _results are scanned again and should erase items that no longer match. The error: Unhandled exception at 0x004016f4 in .exe: 0xC0000005: Access violation reading location 0x0090c000. // Receives data DWORD buffer; for (vector<memblock>::iterator it = MemoryScanner::_results.begin(); it != MemoryScanner::_results.end(); ++it) { // Reads data from an area of memory into buffer ReadProcessMemory(MemoryScanner::_hProc, (LPVOID)(*it).address, &buffer, sizeof(buffer), NULL); if (value != buffer) { MemoryScanner::_results.erase(it); // where the program breaks } }

  • Which to use - "operator new" or "operator new[]" - to allocate a block of raw memory in C++?

    - by sharptooth
    My C++ program needs a block of uninitialized memory. In C I would use malloc() and later free(). In C++ I can either call ::operator new or ::operator new[] and ::operator delete or operator delete[] respectively later. Looks like both ::operator new and ::operator new[] have exactly the same signature and exactly the same behavior. The same for ::operator delete and ::operator delete[]. The only thing I shouldn't do is pairing operator new with operator delete[] and vice versa - undefined behavior. Other than that which pair do I choose and why?

  • Any way to make GetTypes() less brittle.

    - by scope-creep
    I'm iterating through all the types in GAC, GAC_32 and GAC_MSIL looking for specific types, fundamentally to match those using clauses in my source code, so when I compile the source. I'll know exactly what assembly dll's to provide. I'm getting all the file names from each of those directory and applying GetTypes to each assembly in turn and comparing the returned types against my using list. But the problem I have is that GetTypes() keeps crapping out with an exception, when it can't load the types from a loaded assembly. Is their any way to make GetTypes() less brittle. For instance, when parsing this assembly on my box, {blbmmc, Version=6.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35}, it craps out. Any suggestions welcome. I know this is a fairly lengthly process, but I figure i'll eventually use a subset of common assemblies to search, or possibly cache the list of types-assembly dll name at program start. Thanks.

  • how to adjust sliding of scroll according to the value calculated by me?

    - by cng
    I am working on scroll. I have made a program wherein if the scroll box is in particular range of the panel then it automatically moves to a particular position in the slider. For eg, I have a panel of size 500. the scroll has height of 100. Now the total intervals are 5. Now if i slide the scroll box at a position 225 then i want that it automatically slides to the start of that interval that is at position 200. or if i slide to position 450 then instead of staying there it goes to position 400. Is it possible?

  • What is the best, python or bash for selectively concatenating lots of files?

    - by Werner
    Hi, I have around 20000 files coming from the output of some program, and their names follow the format: data1.txt data2.txt ... data99.txt data100.txt ... data999.txt data1000.txt ... data20000.txt I would like to write a script that gets as input argument the number N. Then it makes blocks of N concatenated files, so if N=5, it would make the following new files: data_new_1.txt: it would contain (concatenated) data1.txt to data5.txt (like cat data1.txt data2.txt ... data_new_1.txt ) data_new_2.txt: it would contain (concatenated) data6.txt to data10.txt ..... I wonder what do you think would be the best approach to do this, whether bash, python or another one like awk, perl, etc. The best approach I mean in terms of simplest code. Thanks

  • Android Terminal and Log Dumping

    - by J3hova
    I am trying to send terminal commands programmaticly from an android activity. At the moment I'm using something like the following: Process process = null; DataOutputStream os = null; process = Runtime.getRuntime().exec("su"); os = new DataOutputStream(process.getOutputStream()); os.writeBytes("./data/program1\n"); os.writeBytes("./data/program2\n"); os.writeBytes("exit\n"); os.flush(); However, my program1 is failing to run successfully and I believe it is due to inadequate user permissions. Now for my question: Does anyone know how I can dump the terminal to a file and save it on the phone or sdcard? The program is tying into the terminal to feed it commands, I want to know a way to open a connection the otherway and access the (what is normally visual on a terminal screen) output.

  • Design cache mechanism

    - by Delashmate
    Hi All, I got assignment to write design for cache mechanism, This is my first time writing a design document, Our program display images for doctors, and we wan't to reduce the parsing time of the images So we want to save the parsed data in advance (in files or inside database) Currently I have several design key ideas Handle locks - each shared data structure should be handled, also files Test - add test to verify the data from the cache is equal to the data from the files To decouple the connection to the database- not to call directly to the database Cleanup mechanisem- to delete old files if the cahce directory exceed configurable threshold Support config file Support performance tool in the feature I will also add class diagram, data flow charts, and workflow What do you think I should add to the key ideas? Do you know good link to atricales about design? Thanks in advance, Dan

  • Is there a way to force CoreImage to use the GPU?

    - by NSSplendid
    We are having the following problem: a series of Core Image filters runs constantly in our program. When evaluating on my Macbook Pro, Core Image decides to schedule all graphics computation on the GPU, as expected. When using a MacPro, however, CI uses the CPUs! This is a problem, as we need them for other processing. [1] The question now is: Can one tell CI to run exclusively on the GPU? [1] Both hardware sets are of the newest kind. The MacPro has 8 Cores.

  • mapping rect in small image to larger image (in order to do a copyPixels operation)

    - by skinnyTOD
    Hi all - this is (I think) a relatively simple math question but I've spent a day banging my head against it and have only the dents and no solution... I'm coding in actionscript 3 - the functionality is: large image loaded at runtime. The bitmapData is stored and a smaller version is created to display on the available screen area (I may end up just scaling the large image since it is in memory anyway). The user can create a rectangle hotspot on the smaller image (the functionality will be more complex: multiple rects with transparency: example a donut shape with hole, etc) 3 When the user clicks on the hotspot, the rect of the hotspot is mapped to the larger image and a new bitmap "callout" is created, using the larger bitmap data. The reason for this is so the "callout" will be better quality than just scaling up the area of the hotspot. The image below shows where I am at so far- the blue rect is the clicked hotspot. In the upper left is the "callout" - copied from the larger image. I have the aspect ratio right but I am not mapping to the larger image correctly. Ugly code below... Sorry this post is so long - I just figured I ought to provide as much info as possible. Thanks for any tips! --trace of my data values *source BitmapDada 1152 864 scaled to rect 800 600 scaled BitmapData 800 600 selection BitmapData 58 56 scaled selection 83 80 ratio 1.44 before (x=544, y=237, w=58, h=56) (x=544, y=237, w=225.04, h=217.28) * Image here: http://i795.photobucket.com/albums/yy237/skinnyTOD/exampleST.jpg public function onExpandCallout(event:MouseEvent):void{ if (maskBitmapData.getPixel32(event.localX, event.localY) != 0){ var maskClone:BitmapData = maskBitmapData.clone(); //amount to scale callout - this will vary/can be changed by user var scale:Number =150 //scale percentage var normalizedScale :Number = scale/=100; var w:Number = maskBitmapData.width*normalizedScale; var h:Number = maskBitmapData.height*normalizedScale; var ratio:Number = (sourceBD.width /targetRect.width); //creat bmpd of the scaled size to copy source into var scaledBitmapData:BitmapData = new BitmapData(maskBitmapData.width * ratio, maskBitmapData.height * ratio, true, 0xFFFFFFFF); trace("source BitmapDada " + sourceBD.width, sourceBD.height); trace("scaled to rect " + targetRect.width, targetRect.height); trace("scaled BitmapData", bkgnImageSprite.width, bkgnImageSprite.height); trace("selection BitmapData", maskBitmapData.width, maskBitmapData.height); trace("scaled selection", scaledBitmapData.width, scaledBitmapData.height); trace("ratio", ratio); var scaledBitmap:Bitmap = new Bitmap(scaledBitmapData); var scaleW:Number = sourceBD.width / scaledBitmapData.width; var scaleH:Number = sourceBD.height / scaledBitmapData.height; var scaleMatrix:Matrix = new Matrix(); scaleMatrix.scale(ratio,ratio); var sRect:Rectangle = maskSprite.getBounds(bkgnImageSprite); var sR:Rectangle = sRect.clone(); var ss:Sprite = new Sprite(); ss.graphics.lineStyle(8, 0x0000FF); //ss.graphics.beginFill(0x000000, 1); ss.graphics.drawRect(sRect.x, sRect.y, sRect.width, sRect.height); //ss.graphics.endFill(); this.addChild(ss); trace("before " + sRect); w = uint(sRect.width * scaleW); h = uint(sRect.height * scaleH); sRect.inflate(maskBitmapData.width * ratio, maskBitmapData.height * ratio); sRect.offset(maskBitmapData.width * ratio, maskBitmapData.height * ratio); trace(sRect); scaledBitmapData.copyPixels(sourceBD, sRect, new Point()); addChild(scaledBitmap); scaledBitmap.x = offsetPt.x; scaledBitmap.y = offsetPt.y; } }

  • How do I create a certain control using Windows Forms in Visual C++?

    - by Dalze
    I am new to using Windows Forms in C++ (and just in general), and I am not exactly sure of the name or if it's even possible to do. Currently I am currently working on a school project in which we must make a program for an imaginary bookstore. I am trying right now to make a sort of list that shows what the "customer" is buying. I have to make it sort by price and ISBN and any other variable that the book has. In essence I am trying to make something like the following: I just need to know how to get started. I can't figure out what the name of the control is or how to even get it to sort every time the user clicks on the header.

  • C or C++: how do loaders/wrappers work?

    - by guitar-
    Here's an example of what I mean... User runs LOADER.EXE program LOADER.EXE downloads another EXE but keeps it all in memory without saving it to disk Runs the downloaded EXE just as it would if it were executed from disk, but does it straight from memory I've seen a few applications like this, and I've never seen an example or an explanation of how it works. Does anyone know? Another example is having an encrypted EXE embedded in another one. It gets extracted and decrypted in memory, without ever being saved to disk before it gets executed. I've seen that one used in some applications to prevent piracy.

  • What is a good balance for having developers learn at work

    - by Mel
    So now I am the manager. One of the things I always promised myself I would do is have the other developers focus on learning new stuff. In fact I even want to force them to read a couple books that really helped me learn to program. However now I am also accountable for the product getting finished. I have this vision of everyone reading books instead of working and me getting fired. What is the best way to work learning into the developers schedules, especially for the ones that just don't care to learn. How much time should be spent on learning in a work week?

  • Any tools can randomly generate the source code according to a language grammar?

    - by wbsun
    A C program source code can be parsed according to the C grammar(described in CFG) and eventually turned into many ASTs. I am considering if such tool exists: it can do the reverse thing by firstly randomly generating many ASTs, which include tokens that don't have the concrete string values, just the types of the tokens, according to the CFG, then generating the concrete tokens according to the tokens' definitions in the regular expression. I can imagine the first step looks like an iterative non-terminals replacement, which is randomly and can be limited by certain number of iteration times. The second step is just generating randomly strings according to regular expressions. Is there any tool that can do this?

  • Why isn't the new() generic constraint satisfied by a class with optional parameters in the construc

    The following code fails to compile, producing a "Widget must be a non-abstract type with a public parameterless constructor" error. I would think that the compiler has all of the information it needs. Is this a bug? An oversight? Or is there some scenario where this would not be valid? public class Factory<T> where T : new() { public T Build() { return new T(); } } public class Widget { public Widget(string name = "foo") { Name = name; } public string Name { get; set; } } public class Program { public static void Main() { var widget = new Widget(); // this is valid var factory = new Factory<Widget>(); // compiler error } }

  • iPhone view architecture question

    - by Joe
    So I have (for instance) three views: A: root view B: a view functionally identical to root C: a data entry view which collects a few piece of info What I'm trying to do is reuse C to supply the data it collects to either A or B. It should supply the data to whichever of the two it is pushed onto. The data for A is similar, but functionally distinct, to what collects for B. Right now, I'm passing data from C to A or B via a singleton class. What I'm trying to avoid is having two instances of C, one to supply data to A and B (because, in actuality, the program will have 5 total views like C. Does the question make sense?

  • Artificial Intelligence - What to put in, or leave out, and what can be inferred?

    - by D Scott
    I was having a discussion with a coworker (while we were programming) about AI. We were talking about emotions/feelings and if you should choose to leave any out. I asked him, "Would you leave out racism or hate?" and if you did leave those out, what, if any, other emotions might lead to the AI learning the left out emotions or feelings. Should you PROGRAM in measures to stop the AI from learning those feelings? If you teach Love, does it need to know hurt? Or would it learn hurt? If it then knew Hurt would it connect it with Dislike, Hurt and Dislike could that then lead to some other non-programmed emotion? Such as hate? All while tele-commuting from home.
