  • Winelib & XCode

    - by Chris Becke
    Does anyone have any experience and/or tips wrt using Xcode to build winlib binaries on the Mac? As part of a Windows - Mac OS X crossplatform port i'm looking at an initial winelib port of the app before reworking the windowing to use Cocoa. None of the winelib tutorials ive seen so far mention anything other than command line builds using make files and winegcc, so Im wondering if its worth bothering at all trying to get an Xcode project built linking against winelib.

  • about python scripting

    - by kmitnick
    I have this code class HNCS (ThreadingTCPServer): def verify_request(self, request, client_address): for key in connections: if connections[key].client_address[0] == client_address[0]: if client_address[0] != '127.0.0.1': return False return True def welcome(self): return '''______________________________________________________ ------------------------------------------------------ %s ______________________________________________________ ------------------------------------------------------ * Server started %s * Waiting for connections on port %i ''' % (gpl, ctime(), PORT) I only can't figure out the line where it says if connections[key].client_address[0] == client_address[0] how come we used client_address as an attribute after dictionary???

  • does the concept of flow apply to tcp as well as udp?

    - by liv2hak
    I have a very large network trace file which contains both tcp and udp packets.I want to find out the flows in the trace file.For that I have a hash function which takes in source ip address,destination ip address,source port,destination port and protocol.In case of TCP I can understand that the flow means all the packets which have the same 5 parameters same.But what does it mean in case of UDP.how does the concept of flow apply in case of UDP.? I am a novice in packet processing.

  • Windows version of the Unix touch command

    - by Paul Hargreaves
    I'm looking for a Windows port of the UNIX touch command. I don't want to install an entire MKS toolkit just for the one tool. Is there a native port available somewhere or a command in Windows that does the same thing and supports features like all files in a directory by wildcard? Specifically I'm after changing mtime, ctime and atime for a project that reports ages of files based on... mtime, ctime and atime.

  • Access JBOSS Tomcat Web Application from Remote Computer

    - by Rod
    Hi, I just deployed a web application on JBOSS 4.2. It can be accessed locally only (http://localhost:8080/myApp). I cant access it from remote computer by typing its domain: (www.hostname.com:8080/myApp). I added Port 8080 as Exception in Windows Firewall. Note that the host (www.hostname.com) is reachable from remote computers via IIS on port 80. Thanks, Rod

  • sql 2008 express connection problems

    - by user163457
    Hi, I've just installed a fresh copy of SQL 2008 Express. before I did anything I opened Management Studio and successfully connected using Window Authentication. However I tried to run the following on the command line "telnet localhost 1433" and got the error "Could not open connection to the host, on port 1433: Connect failed" I checked netstat and there is nothing listening on port 1433. Before I go any further, is there a problem with the install? thanks, Shane

  • Supporting more than one codebase in ANSI-C

    - by Ilker Murat Karakas
    I am working on a project, with an associated Ansi-C code base. (let me call this the 'main' codebase). I now am confronted with a typical problem (stated below), which I believe I would be able to solve much easily if I had an object-oriented language at hand. The problem is this: I will have to start more than one codebases; i.e. I will have to start supporting a parallel codebase (even maybe more in the future). The initial codebases for all the new (i.e. parallel) codebases will initially be identical as the old (i.e. 'main') codebase. As we are talking about the 'C' language, I have till now been thinking of adding '#ifdef' statements to code, and writing the branch-spacific code inside those 'ifdef' blocks. Hoping that I made the problem clear (enough!), I would like to hear thoughts on clever patterns that would help me handle this problem elegantly in Ansi C. Cheers

  • SQL Server: error when connecting

    - by atricapilla
    The application I'm using tries to connect SQL Server named instance running on a dedicated database server. Here's the error I'm getting: The TCP/IP connection to the host <instance_name>, port 1433 has failed. Error: Connection refused: connect. Is the firewall blocking my access or what? Should I dedicate a different port for this application?

  • Do Instances Share Same Services? - SQL Server

    - by peace
    Lets say i installed two named SQL Server 2008 instances e.g. A and B, will i have two services of each type e.g. two analysis service, two reporting service and so on, one service for A and the other for B? If yes, then it is known a service listens on a port number, how two same services going to listen on the port? I hope this is clear enough. Thanks

  • Real life usage of the projective plane theory

    - by Elazar Leibovich
    I'm learning about the theory of the projective plane. Very generally speaking, it is an extension of the plane, which includes additional points which are defined as the intersection points of two parallel lines. In the projective plane, every two lines have an interesection point. Whether they're parallel or not. Every point in the projective plane can be represented by three numbers (you actually need less than that, but nevemind now). Is there any real life application which uses the projective plane? I can think that, for instance, a software which needs to find the intersections of a line, can benefit from always having an intersection point which might lead to simpler code, but is it really used?

  • global static boolean pointer causes segmentation fault using pthread

    - by asksw0rder
    New to pthread programming, and stuck on this error when working on a C++&C mixed code. What I have done is to call the c code in the thread created by the c++ code. There is a static boolean pointer used in the thread and should got free when the thread finishes. However I noticed that every time when the program processed into the c function, the value of the boolean pointer would be changed and the segmentation fault then happened due to the free(). Detail code is as follows: static bool *is_center; // omit other codes in between ... void streamCluster( PStream* stream) { // some code here ... while(1){ // some code here ... is_center = (bool*)calloc(points.num,sizeof(bool)); // start the parallel thread here. // the c code is invoked in this function. localSearch(&points,kmin, kmax,&kfinal); // parallel free(is_center); } And the function using parallel is as follows (my c code is invoked in each thread): void localSearch( Points* points, long kmin, long kmax, long* kfinal ) { pthread_barrier_t barrier; pthread_t* threads = new pthread_t[nproc]; pkmedian_arg_t* arg = new pkmedian_arg_t[nproc]; pthread_barrier_init(&barrier,NULL,nproc); for( int i = 0; i < nproc; i++ ) { arg[i].points = points; arg[i].kmin = kmin; arg[i].kmax = kmax; arg[i].pid = i; arg[i].kfinal = kfinal; arg[i].barrier = &barrier; pthread_create(threads+i,NULL,localSearchSub,(void*)&arg[i]); } for ( int i = 0; i < nproc; i++) { pthread_join(threads[i],NULL); } delete[] threads; delete[] arg; pthread_barrier_destroy(&barrier); } Finally the function calling my c code: void* localSearchSub(void* arg_) { // omit some initialize code... // my code begin_papi_thread(&eventSet); // Processing k-means, omit codes. // is_center value will be updated correctly // my code end_papi_thread(&eventSet); // when jumping into this, error happens return NULL; } And from gdb, what I have got for the is_center is: Breakpoint 2, localSearchSub (arg_=0x600000000000bc40) at streamcluster.cpp:1711 1711 end_papi_thread(&eventSet); (gdb) s Hardware watchpoint 1: is_center Old value = (bool *) 0x600000000000bba0 New value = (bool *) 0xa93f3 0x400000000000d8d1 in localSearchSub (arg_=0x600000000000bc40) at streamcluster.cpp:1711 1711 end_papi_thread(&eventSet); Any suggestions? Thanks in advance!

  • Ruby: How can I have a Hash take multiple keys?

    - by zxcvbnm
    I'm taking 5 strings (protocol, source IP and port, destination IP and port) and using them to store some values in a hash. The problem is that if the IPs or ports are switched between source and destination, the key is supposed to be the same. If I was doing this in C#/Java/whatever I'd have to create a new class and overwrite the hashcode()/equals() methods, but that seems error prone from the little I've read about it and I was wondering if there would be a better alternative here.

  • multidimensional vector rotation and angle computation -- how?

    - by macias
    Input: two multidimensional (for example dim=8) vectors a and b. I need to find out the "directed" angle (0-2*Pi, not 0-Pi) between those vectors a and b. And if they are not parallel I need to rotate vector b in plane a,b by "directed" angle L. If they are parallel, plane does not matter, but angle of rotation is still the same L. For 2d and 3d this is quite easy, but for more dimensions I am lost, I didn't find anything on google, and I prefer using some already proved&tested equations (avoiding errors introduced by my calculations :-D). Thank you in advance for tips, links, etc. Edit: dimension of the space is the same as dimension of the vectors.

  • call multiple c++ functions in python using threads

    - by wiso
    Suppose I have a C(++) function taking an integer, and it is bound to (C)python with python api, so I can call it from python: import c_module c_module.f(10) now, I want to parallelize it. The problem is: how does the GIL work in this case? Suppose I have a queue of numbers to be processed, and some workers (threading.Thread) working in parallel, each of them calling c_module.f(number) where number is taken from a queue. The difference with the usual case, when GIL lock the interpreter, is that now you don't need the interpreter to evaluate c_module.f because it is compiled. So the question is: in this case the processing is really parallel?

  • How does porting between Linux and Windows work?

    - by Matt
    If a particular piece of software is made to be run on one platform and the programmer/company/whatever wants to port it to the other, what exactly is done? I mean, do they just rewrite linux or windows-specific references to the equivalent in the other? Or is an entire rewrite necessary? Just trying to understand what makes it so cost-prohibitive that so many major vendors don't port their software to Linux (specifically thinking about Adobe) Thanks
