31,172,911 | 0 | <p>When a reference to a cell is made via a <code>UITableView</code>, (usually by iOS, when loading your view), iOS calls the methods in its lifecycle - e.g., <code>heightForRowAtIndexPath</code>, <code>editingStyleForRowAtIndexPath</code> to work out how to display it etc.</p> <p>So your source of an infinite loop is that you make a reference to a cell, inside a method that is called when a reference to a cell is made ;)</p> <p>To fix this, you should reference back to your data source, instead of asking the cell directly about itself. If you have a class set up as a data collection, this is easy.</p> |

31,350,180 | 0 | <p>Given that the site you linked to adds the ID to the body based on the page that you are on, your css is fine (although, you have a trailing comma before the open bracket that should be removed); it's the hex code on your background color that is invalid. You have 7 characters when there should only be 6: #FFD3CEf</p> <p>Generally speaking, the best way to handle special styles on the active page link is just to add a class (ex. "active") to the link that corresponds with the current page you are on, and then apply the special styles to that .active class in your css.</p> |

Where are these strings then stored? I understand as well that one can programmatically add strings to the dialog box during dialog init, obtaining them is another story. </p> <p>Nevertheless, my problem is that I don't have access to the dialog object, neither is it visible at the time I wish to obtain the option strings.

Have your table view's delegate return a custom view for each header instead bu implementing -tableView:viewForHeaderInSection:.

14,964,024 | 0 | How do I symbolicate a copy/pasted crash report? <p>I have a user who is experiencing a crash using the app store version of an iPhone app. The crash is not reported via iTunes connect and the user is unable to sync with iTunes and get me the .crash file (they don't have a computer). The user is, however, able to copy and paste the crash report from the phone under "Settings > general > about > Diagnostics & usage data". </p> <p>I took this users copied crash report and manually pasted it into a text file and renamed it with the .crash extension. When I import this manually created .crash report into XCode's Organizer, I am not able to symbolicate it.

874,070 | 0 | Are there any USB stick runnable, no-install, cross platform software frameworks (with GUI)? <p>Does anyone know of a good software development framework or similar that has the following properties?</p> <ul> <li>Cross platform: it should be runnable on XP, Vista, OSX and common versions of Linux (such as Ubuntu and Kubuntu).</li> <li>No installation: Be able to run the software from a USB stick without having to copy anything to the host machine.</li> <li>Have good GUI support (this is why <a href="http://stackoverflow.com/questions/383757/ok-programming-language-from-usb-stick-with-no-installation">this question</a> doesn't give a suitable answer, as far as I can tell).</li> <li>Permissive licensing such as LGPL or BSD or such.</li> </ul> <p>Among the softer requirements are having a set of abstractions for the most common backend functionality, such as sockets, file IO, and so on (There is usually some platform specific adaptations necessary), and supporting a good language such as Python or C++, though it is usually fun to learn a new one (i.e. not perl).</p> <p>I think possible candidates are Qt 4.5 or above (but IFAIK Qt software will not run on Vista without any installation(?)), some wxWidgets or maybe wxPython solution, perhaps gtkmm. The examples I have found have failed on one or another of the requirements. This does not mean that no such examples exist, it just means that I have not found any. So I was wondering if anyone out there know of any existing solutions to this?</p> <p>Some clarifications;</p> <ul> <li>By "framework" I mean something like Qt or gtkmm or python with a widget package.</li> <li>This is about being able to run the finished product on multiple platforms, from a stick, without installation, it is not about having a portable development environment.</li> <li>It is not a boot stick.</li> <li>It is ok to have to build the software specifically for the different targets, if necessary.</li> </ul> <p>The use case I am seeing is that you have some software that you rely on (such as project planning, administration of information, analysis tools or similar) that:</p> <ul> <li>does not rely on having an internet connection being available.</li> <li>is run on different host machines where it is not really ok to install anything.</li> <li>is moved by a user via a physical medium (such as a USB stick).</li> <li>is run on different operating systems, such as Windows, Vista, Ubuntu, OSX.</li> <li>works on the same data on these different hosts (the data can be stored on the host or on the stick).</li> <li>is not really restricted in how big the bundled framework is (unless it is several gigabytes, which is not really realistic).</li> </ul> <p>It is also ok to have parallel installations on the stick as long as the software behaves the same and can work on the same data when run on the different targets. </p> <p>A different view on the use case would be that I have five newly installed machines with Vista, XP, OSX, Ubuntu and Kubuntu respectively in front of me. I would like to, without having to install anything new on the machines, be able to run the same software from a single USB stick (meeting the above GUI requirements and so on) on each of these five machines (though, if necessary from different bundles on the stick).</p> <p>Is this possible?</p> <p>Edit: I have experimented a little with a Qt app that uses some widgets and a sqlite database. It was easy to get it to work on an ubuntu dist and on osx. For windows xp and vista I had to copy QtCored4.dll, QtGuid4.dll, QtSqld4.dll and mingwm10.dll to distribution directory (this was debug code) and I copied the qsqlited4.dll to a folder named "sqldrivers" in the distribution directory.</p> |

9,894,203 | 0 | <p>If you have many options, you usually create a seperate table, only with an id and description (or name). To Connect these two tables, you insert a field into the CHECKLIST_ANSWER-Table, and define it as a foreign key, which references to the id (primary key) of the new table, I have mentioned first.</p> <p>Hope it is clear :)</p> |

17,452,864 | 0 | <p>This answer is probably going to need a little refinement from the community, since it's been a long while since I worked in this environment, but here's a start -</p> <p>Since you're new to multi-threading in C++, start with a simple project to create a bunch of pthreads doing a simple task.</p> <p>Here's a quick and small example of creating pthreads:</p> <pre><code>#include <stdio.h> #include <stdlib.h> #include <pthread.h> void* ThreadStart(void* arg); int main( int count, char** argv) { pthread_t thread1, thread2; int* threadArg1 = (int*)malloc(sizeof(int)); int* threadArg2 = (int*)malloc(sizeof(int)); *threadArg1 = 1; *threadArg2 = 2; pthread_create(&thread1, NULL, &ThreadStart, (void*)threadArg1 ); pthread_create(&thread2, NULL, &ThreadStart, (void*)threadArg2 ); pthread_join(thread1, NULL); pthread_join(thread2, NULL); free(threadArg1); free(threadArg2); } void* ThreadStart(void* arg) { int threadNum = *((int*)arg); printf("hello world from thread %d\n", threadNum); return NULL; } </code></pre> <p>Next, you're going to be using multiple opus decoders. Opus appears to be thread safe, so long as you create separate OpusDecoder objects for each thread. </p> <p>To feed jobs to your threads, you'll need a list of pending work units that can be accessed in a thread safe manner. You can use <code>std::vector</code> or <code>std::queue</code>, but you'll have to use locks around it when adding to it and when removing from it, and you'll want to use a counting semaphore so that the threads will block, but stay alive, while you slowly add workunits to the queue (say, buffers of files read from disk).</p> <p>Here's some example code similar from above that shows how to use a shared queue, and how to make the threads wait while you fill the queue:</p> <pre><code>#include <stdio.h> #include <stdlib.h> #include <pthread.h> #include <queue> #include <semaphore.h> #include <unistd.h> void* ThreadStart(void* arg); static std::queue<int> workunits; static pthread_mutex_t workunitLock; static sem_t workunitCount; int main( int count, char** argv) { pthread_t thread1, thread2; pthread_mutex_init(&workunitLock, NULL); sem_init(&workunitCount, 0, 0); pthread_create(&thread1, NULL, &ThreadStart, NULL); pthread_create(&thread2, NULL, &ThreadStart, NULL); // Make a bunch of workunits while the threads are running. for (int i = 0; i < 200; i++ ){ pthread_mutex_lock(&workunitLock); workunits.push(i); sem_post(&workunitCount); pthread_mutex_unlock(&workunitLock); // Pretend that it takes some effort to create work units; // this shows that the threads really do block patiently // while we generate workunits. usleep(5000); } // Sometime in the next while, the threads will be blocked on // sem_wait because they're waiting for more workunits. None // of them are quitting because they never saw an empty queue. // Pump the semaphore once for each thread so they can wake // up, see the empty queue, and return. sem_post(&workunitCount); sem_post(&workunitCount); pthread_join(thread1, NULL); pthread_join(thread2, NULL); pthread_mutex_destroy(&workunitLock); sem_destroy(&workunitCount); } void* ThreadStart(void* arg) { int workUnit; bool haveUnit = true; while(haveUnit) { sem_wait(&workunitCount); pthread_mutex_lock(&workunitLock); // Figure out if there's a unit, grab it under // the lock, then release the lock as soon as we can. // After we release the lock, then we can 'process' // the unit without blocking everybody else. haveUnit = !workunits.empty(); if ( haveUnit ) { workUnit = workunits.front(); workunits.pop(); } pthread_mutex_unlock(&workunitLock); // Now that we're not under the lock, we can spend // as much time as we want processing the workunit. if ( haveUnit ) { printf("Got workunit %d\n", workUnit); } } return NULL; } </code></pre> |

16,756,354 | 0 | <p>The short answer: Objects. Object oriented programming allows you to encapsulate data so that it doesn't pollute the global namespace. As your projects grow larger, it becomes unmaintainable to have all your data in the global namespace. Objects allow you to group data and methods into meaningful units, which can then be re-used and maintained more easily.</p> <p>So for instance with the example you provided we could make deck and hand objects. This then allows us to create multiple deck and hands easily because these objects encapsulate and manage their data.</p> <p>As a rough outline of how you might organize your classes / methods:</p> <pre><code>class Deck def shuffle end def draw_hand end end class Hand end class Card end </code></pre> |

39,441,513 | 0 | Variable latency in Windows networking <p>I have a PLC that sends UDP packets every 24ms. "Simultaneously" (i.e. within a matter of what should be a few tens or at most hundreds of microseconds), the same PLC triggers a camera to snap an image. There is a Windows 8.1 system that receives both the images and the UDP packets, and an application running on it that should be able to match each image with the UDP packet from the PLC.</p> <p>Most of the time, there is a reasonably fixed latency between the two events as far as the Windows application is concerned - 20ms +/- 5ms. But sometimes the latency rises, and never really falls. Eventually it goes beyond the range of the matching buffer I have, and the two systems reset themselves, which always starts back off with "normal" levels of latency.</p> <p>What puzzles me is the variability in this variable latency - that sometimes it will sit all day on 20ms +/- 5ms, but on other days it will regularly and rapidly increase, and our system resets itself disturbingly often.</p> <p>What could be going on here? What can be done to fix it? Is Windows the likely source of the latency, or the PLC system?</p> <p>I 99% suspect Windows, since the PLC is designed for real time response, and Windows isn't. Does this sound "normal" for Windows? If so, even if there are other processes contending for the network and/or other resources, why doesn't Windows ever seem to catch up - to rise in latency when contention occurs, but return to normal latency levels after the contention stops?</p> <p>FYI: the Windows application calls <code>SetPriorityClass( GetCurrentProcess(), REALTIME_PRIORITY_CLASS )</code> and each critical thread is started with <code>AfxBeginThread( SomeThread, pSomeParam, THREAD_PRIORITY_TIME_CRITICAL )</code>. There is as little as possible else running on the system, and the application only uses about 5% of the available Quad-core processor (with hyperthreading, so 8 effective processors). There is no use of <code>SetThreadAffinityMask()</code> although I am considering it.</p> |

40,417,777 | 0 | log4cplusud.lib missing when building with VisualStudio <p>i already have a complete VS Solution (that is working on other systems) and i am trying to get it to build on my computer aswell.</p> <p>The program is using log4cplus to (obviously) log - i already included the needed files, but when building VS tells me, that <code>log4cplusUD.lib</code> is missing. When searching through log4cplus i only found <code>log4cplusS.lib</code> and <code>log4cplusD.lib</code></p> <p>Does somebody know how to get this library or how to adjust VS to accept the other libraries? Thanks in advance :)</p> |
