  • Can I use IP addresses to limit API access

    - by ed209
    I have a mini API that is only for an app I have built. The API service is on a separate domain to my app. I make jsonp calls to it and receive json in return. Therefore I only want my app to be able to access it. Can I just list a series of IP addresses for my app and allow them? Is there a better way to stop requests from anyone else to my API?

  • jQuery: Returns only part of a text

    - by Warrantica
    I want to write a jQuery function that will return only a part of a given text. For example, in the text: http://somesubdomain.somesite.com/ How can I write a function so that it returns the text "somesubdomain"? In other words, I want to "subtract" the text "http://" and ".somesite.com/". Thanks in advance

  • Getting a substring in Ruby by x number of chars

    - by wotaskd
    I'm trying to produce some Ruby code that will take a string and return a new one, with a number x number of characters removed from its end - these can be actual letters, numbers, spaces etc. Ex: given the following string a_string = "a1wer4zx" I need a simple way to get the same string, minus - say - the 3 last digits. In the case above, that would be "a1wer". The way I'm doing it right now seems very convoluted: an_array = a_string.split(//,(a_string.length-2)) an_array.pop new_string = an_array.join Any ideas?

  • How to get latest files in C#

    - by Newbie
    I have some files with same name but with different dates. Basically we are finding the files with most recent dates The file patterns are <FileNames><YYYYMMDD><FileExtension> e.g. test_20100506.xls indicates <FileNames> = test_ <YYYYMMDD> = 20100506 <FileExtension> = .xls Now in the source folder, the files are standardization_20100503.xls, standardization_20100504.xls, standardization_20100305.xls, replacement_20100505.xls As can be seen that, standardization_.xls are 3 in numbers but replacement_.xls is only 1. The output will be a list of file names whose content will be standardization_20100504.xls and replacement_20100505.xls Because among all the standardization_.xls is the most recent one and replacement_.xls is also the same. I have tried with my own logic but somehow failed. My idea is as under private static void GetLatestFiles(ref List<FileInfo> validFiles) { List<FileInfo> validFilesTemp = new List<FileInfo>(); for (int i = 0; i < validFiles.Count; i++) { for (int j = i+1; j < validFiles.Count; j++) { string getFileTextX = ExtractText(validFiles[i].Name); string getFileTextY = ExtractText(validFiles[j].Name); if (getFileTextX == getFileTextY) { int getFileDatesX = Convert.ToInt32(ExtractNumbers(validFiles[i].Name)); int getFileDatesY = Convert.ToInt32(ExtractNumbers(validFiles[j].Name)); if (getFileDatesX > getFileDatesY) { validFilesTemp.Add(validFiles[i]); } else { validFilesTemp.Add(validFiles[j]); } } } } validFiles.Clear(); validFiles = validFilesTemp; } The ExtractNumbers is: public static string ExtractNumbers(string expr) { return string.Join(null, System.Text.RegularExpressions.Regex.Split(expr, "[^\\d]")); } and the ExtractText is public static string ExtractText(string expr) { return string.Join(null, System.Text.RegularExpressions.Regex.Split(expr, "[\\d]")); } I am using c#3.0 and framework 3.5 Help needed .. it's very urgent Thanks .

  • element-wise lookup on one ndarray to another ndarray of different shapes

    - by fahhean
    Hi, I am new to numpy. Am wonder is there a way to do lookup of two ndarray of different shapes? for example, i have 2 ndarrays as below: X = array([[0, 3, 6], [3, 3, 3], [6, 0, 3]]) Y = array([[0, 100], [3, 500], [6, 800]]) and would like to lookup each element of X in Y, then be able to return the second column of Y: Z = array([[100, 500, 800], [500, 500, 500], [800, 100, 500]]) thanks, fahhean

  • URL redirection if wrong url

    - by xRobot
    I have this method in my book model: def get_absolute_url(self): return "/book/%s/%s/%i/%i/" % ( self.book_title, self.book_editor, self.book_pages, self.id) So the urls of each book are like this: example.com/book/the-bible/gesu-crist/938/12/ I want that if there is an error in the url, then I get redirected to the real url by using book.id in the end of the url. For example if I go to: example.com/book/A-bible/gesu-crist/938/12/ the I will get redirected to: example.com/book/the-bible/gesu-crist/938/12/ How can I do that ?

  • MySQL select date, join statistic data - how?

    - by Webnet
    I have some statistics I need to report on a monthly basis. I need my query to return 0's for statistics which aren't there. The only way I know to do this is to use SQL to generate a list of days within the specified time period and LEFT JOIN the statistic data that I need to report on. Problem is.... I've never not selected from a table like that... how do I do that?

  • Wake up thread blocked on accept() call

    - by selbie
    Sockets on Linux question I have a worker thread that is blocked on an accept() call. It simply waits for an incoming network connection, handles it, and then returns to listening for the next connection. When it is time for the program to exit, how do I signal this network worker thread (from the main thread) to return from the accept() call while still being able to gracefully exit its loop and handle it's cleanup code. Some things I tried: 1. pthread_kill to send a signal. Feels kludgy to do this, plus it doesn't reliably allow the thread to do it's shutdown logic. Also makes the program terminate as well. I'd like to avoid signals if at all possible. pthread_cancel. Same as above. It's a harsh kill on the thread. That, and the thread may be doing something else. Closing the listen socket from the main thread in order to make accept() abort. This doesn't reliably work. Some constraints: If the solution involves making the listen socket non-blocking, that is fine. But I don't want to accept a solution that involves the thread waking up via a select call every few seconds to check the exit condition. The thread condition to exit may not be tied to the process exiting. Essentially, the logic I am going for looks like this. void* WorkerThread(void* args) { DoSomeImportantInitialization(); // initialize listen socket and some thread specific stuff while (HasExitConditionBeenSet()==false) { listensize = sizeof(listenaddr); int sock = accept(listensocket, &listenaddr, &listensize); // check if exit condition has been set using thread safe semantics if (HasExitConditionBeenSet()) { break; } if (sock < 0) { printf("accept returned %d (errno==%d)\n", sock, errno); } else { HandleNewNetworkCondition(sock, &listenaddr); } } DoSomeImportantCleanup(); // close listen socket, close connections, cleanup etc.. return NULL; } void SignalHandler(int sig) { printf("Caught CTRL-C\n"); } void NotifyWorkerThreadToExit(pthread_t thread_handle) { // signal thread to exit } int main() { void* ptr_ret= NULL; pthread_t workerthread_handle = 0; pthread_create(&workerthread, NULL, WorkerThread, NULL); signal(SIGINT, SignalHandler); sleep((unsigned int)-1); // sleep until the user hits ctrl-c printf("Returned from sleep call...\n"); SetThreadExitCondition(); // sets global variable with barrier that worker thread checks on // this is the function I'm stalled on writing NotifyWorkerThreadToExit(workerthread_handle); // wait for thread to exit cleanly pthread_join(workerthread_handle, &ptr_ret); DoProcessCleanupStuff(); }

  • How to check if a string has earlier been set using iabbr (full match)

    - by Sumit
    I am trying to check if a lhs is already abbreviated in vim. mapcheck, however, seems to have a problem. For example, iabbr swt switch echo mapcheck('sw','i',1) returns "switch" even when "switch" defined for "swt". mapargs seem to return a string even if there is a partial match with the lhs. Is there a way to find if an abbreviation has been defined for the "exact" match, i.e., the above mapcheck returning a "" instead.

  • Mixing C and C++, raw pointers and (boost) shared pointers

    - by oompahloompah
    I am working in C++ with some legacy C code. I have a data structure that (during initialisation), makes a copy of the structure pointed to a ptr passed to its initialisation pointer. Here is a simplification of what I am trying to do - hopefully, no important detail has been lost in the "simplification": /* C code */ typedef struct MyData { double * elems; unsigned int len; }; int NEW_mydata(MyData* data, unsigned int len) { // no error checking data->elems = (double *)calloc(len, sizeof(double)); return 0; } typedef struct Foo { MyData data data_; }; void InitFoo(Foo * foo, const MyData * the_data) { //alloc mem etc ... then assign the STRUCTURE foo.data_ = *thedata ; } C++ code ------------- typedef boost::shared_ptr<MyData> MyDataPtr; typedef std::map<std::string, MyDataPtr> Datamap; class FooWrapper { public: FooWrapper(const std::string& key) { MyDataPtr mdp = dmap[key]; InitFoo(&m_foo, const_cast<MyData*>((*mdp.get()))); } ~FooWrapper(); double get_element(unsigned int index ) const { return m_foo.elems[index]; } private: // non copyable, non-assignable FooWrapper(const FooWrapper&); FooWrapper& operator= (const FooWrapper&); Foo m_foo; }; int main(int argc, char *argv[]) { MyData data1, data2; Datamap dmap; NEW_mydata(&data1, 10); data1->elems[0] = static_cast<double>(22/7); NEW_mydata(&data2, 42); data2->elems[0] = static_cast<double>(13/21); boost::shared_ptr d1(&data1), d2(&data2); dmap["data1"] = d1; dmap["data2"] = d2; FooWrapper fw("data1"); //expect 22/7, get something else (random number?) double ret fw.get_element(0); } Essentially, what I want to know is this: Is there any reason why the data retrieved from the map is different from the one stored in the map?
