  • How to determine if a List is sorted in Java?

    - by FarmBoy
    I would like a method that takes a List<T> where T implements Comparable and returns true or false depending on whether the list is sorted or not. What is the best way to implement this in Java? It's obvious that generics and wildcards are meant to be able to handle such things easily, but I'm getting all tangled up. It would also be nice to have an analogous method to check if the list is in reverse order.

  • Avoiding .gsp extention in a GSP Page Without a Controller

    Using grails 1.2.1 this should be very simple, but still I can't get it to work. In my application /grails-app/views I've added mypage.gsp Plus "/mypage"(view:"mypage") to the mappings block of my URLMapping class. while http://server-name:8080/myapp/mypage.gsp works I'm still getting 404 - page not found when I try to open http://server-name:8080/myapp/mypage Thanks, Guy

  • Octave: importing a large matrix in csv format

    - by Massagran
    I'm trying to import a matrix (about 80.000 rows) from a csv file to Octave. The obvious solution seems something like: load("-ascii","relative_directory/the_file.csv") or maybe renaming the file and trying: load("-ascii", "relative_directory/the_file.txt") Yet I keep getting the error: load: failed to read matrix from file "relative_directory/the_file.csv" or .txt without anymore details. Any tips are appreciated.

    - by CaptainAwesomePants
    I started cloning a SVN repository using git-svn's clone operation. After about 6 hours of importing (it's a bit repo), my computer went and slept on me. Is there a way to resume the operation without redoing all of the initial work?

  • C++ Multithreading with pthread is blocking (including sockets)

    - by Sebastian Büttner
    I am trying to implement a multi threaded application with pthread. I did implement a thread class which looks like the following and I call it later twice (or even more), but it seems to block instead of execute the threads parallel. Here is what I got until now: The Thread Class is an abstract class which has the abstract method "exec" which should contain the thread code in a derive class (I did a sample of this, named DerivedThread) Thread.hpp #ifndef THREAD_H_ #define THREAD_H_ #include <pthread.h> class Thread { public: Thread(); void start(); void join(); virtual int exec() = 0; int exit_code(); private: static void* thread_router(void* arg); void exec_thread(); pthread_t pth_; int code_; }; #endif /* THREAD_H_ */ And Thread.cpp #include <iostream> #include "Thread.hpp" /*****************************/ using namespace std; Thread::Thread(): code_(0) { cout << "[Thread] Init" << endl; } void Thread::start() { cout << "[Thread] Created Thread" << endl; pthread_create( &pth_, NULL, Thread::thread_router, reinterpret_cast<void*>(this)); } void Thread::join() { cout << "[Thread] Join Thread" << endl; pthread_join(pth_, NULL); } int Thread::exit_code() { return code_; } void Thread::exec_thread() { cout << "[Thread] Execute" << endl; code_ = exec(); } void* Thread::thread_router(void* arg) { cout << "[Thread] exec_thread function in thread" << endl; reinterpret_cast<Thread*>(arg)->exec_thread(); return NULL; } DerivedThread.hpp #include "Thread.hpp" class DerivedThread : public Thread { public: DerivedThread(); virtual ~DerivedThread(); int exec(); void Close() = 0; DerivedThread.cpp [...] #include "DerivedThread.cpp" [...] int DerivedThread::exec() { //code to be executed do { cout << "Thread executed" << endl; usleep(1000000); } while (true); //dummy, just to let it run for a while } [...] Basically, I am calling this like the here: DerivedThread *thread; cout << "Creating Thread" << endl; thread = new DerivedThread(); cout << "Created thread, starting..." << endl; thread->start(); cout << "Started thread" << endl; cout << "Creating 2nd Thread" << endl; thread = new DerivedThread(); cout << "Created 2nd thread, starting..." << endl; thread->start(); cout << "Started 2nd thread" << endl; What is working great if I am only starting one of these Threads , but if I start multiple which should run together (not synced, only parallel) . But I discovered, that the thread is created, then as it tries to execute it (via start) the problem seems to block until the thread has closed. After that the next Thread is processed. I thought that pthread would do it unblocked for me, so what did I wrong? A sample output might be: Creating Thread [Thread] Thread Init Created thread, starting... [Thread] Created thread [Thread] exec_thread function in thread [Thread] Execute Thread executed Thread executed Thread executed Thread executed Thread executed Thread executed Thread executed .... Until Thread 1 is not terminated, a Thread 2 won't be created not executed. The process above is executed in an other class. Just for the information: I am trying to create a multi threaded server. The concept is like this: MultiThreadedServer Class has a main loop, like this one: ::inet::ServerSock *sock; //just a simple self made wrapper class for sockets DerivedThread *thread; for (;;) { sock = new ::inet::ServerSock(); this->Socket->accept( *sock ); cout << "Creating Thread" << endl; //Threads (according to code sample above) thread = new DerivedThread(sock); //I did not mentoine the parameter before as it was not neccesary, in fact, I pass the socket handle with the connected socket to the thread cout << "Created thread, starting..." << endl; thread->start(); cout << "Started thread" << endl; } So I thought that this would loop over and over and wait for new connections to accept. and when a new client arrives, I am creating a new thread and give the thread the connected socket as a parameter. In the DerivedThread::exec I am doing the handling for the connected client. Like: [...] do { [...] if (this-sock_-read( Buffer, sizeof(PacketStruc) ) 0) { cout << "[Handler_Base] Recv Packet" << endl; //handle the packet } else { Connected = false; } delete Buffer; } while ( Connected ); So I loop in the created thread as long as the client keeps the connection. I think, that the socket may cause the blocking behaviour. Edit: I figured out, that it is not the read() loop in the DerivedThread Class as I simply replaced it with a loop over a simple cout-usleep part. It did also only execute the first one and after first thread finished, the 2nd one was executed. Many thanks and best regards, Sebastian

    I have tons of data in directory called reports. While doing git merge with another branch I am getting lots of conflicts for files under reports directory. I would like git merge to ignore files under reports. In another words I would like all the data from reports from master and not from lab branch. Is that possible?

  • Using PHP, how to parse the title and meta tags from a HTML page?

    - by Dylan Taylor
    Hey guys, I need to be able to get the TITLE and DESCIPTION metadata out of a page. I've been trying to do this but I've been getting more errors than actual results. (I have an array of about 10 URLS, usually only about 2 of them give me the descrption. I have yet to get the title). So how do I, in PHP, get the Desc and Title from a remote page, and if there is none or if there's an error, ignore it? -Dylan

  • get bash history to vi

    - by nameanyone
    When I try to read bash history into vim, I get nothing. :r !history If I just execute the command, i.e. :!history instead of history I get a snapshot of my terminal as it looked before I started vim. How can I read the output of "history" into vim? Reading the contents of .bash_history won't do as I save history with timestamps: HISTTIMEFORMAT='%Y.%m.%d %R '
