  • How do you reach a "flow" state while programming?

    - by acrosman
    I'm not talking about program flow, but as in the state of working called flow, the state where you can get great work done the most effectively. I find that my current work environment while good in many ways does not allow me to get into a good state of mind for writing code most of the time (my job includes many other functions). If it's critical to get something done I'll often put on head-phones with classical music and try to drown out the office noise around me (and discourage co-workings from asking me questions). I am best able to get work done late in the evening when the house is quite and I've been thinking about the project for most of the day. What tricks have you found when working in less then perfect office environments?

  • How Do I Make a PHP Module with the Vala Programming Language?

    - by Volomike
    This new language called Vala, which is said to be C#-like and supposedly easier than C++ or C, compiles down into C on Linux with the GCC compiler. Sounds great. Now I want to use it to make a PHP module so that slow PHP code can be made in Vala and imported into PHP as a function. How do I accomplish this in Vala? Is it even possible?

  • A Good Final High School AP Computer Science Programming Project?

    - by user297663
    Hey guys this question might seem very specific but I am in need of some ideas for a project to do for my last month or so in my AP Computer Science class. I've been looking at some college final ideas and a lot of them just seem plain boring. At first I thought about writing a IRC client in JAVA but I wouldn't really be learning anything "new" that would help me in the future. Then I thought about doing IPhone/touch apps (I don't have an adroid phone and I can easily get my hands on an itouch) but I would need ideas to make apps for that. I want to do something that is going to feel trivial and need some explanation but will also help me in the long run learning new concepts in computer science. If you guys could help out I would greatly appreciate it. I really only have a month to do this project so try to keep the project inside of that range. Also, I don't mind learning new languages. Thanks :)

  • help needed on libcurl programming in sending HTTP HEAD Request.

    - by Mani
    Hi all, I need clarifications on using libcurl for the following: I need to send an http HEAD request shown as below :: HEAD /mshare/3/30002:12:primary/stream_xNKNVH.mpeg HTTP/1.1 Host: 192.168.70.1:8080 Accept: */* User-Agent: Kreatel_IP-STB getcontentFeatures.dlna.org: 1 The code I wrote (shown below) , sends the HEAD Request in slightly different way: curl_global_init(CURL_GLOBAL_ALL); CURL* ctx = NULL; const char *url = "http://192.168.70.1:8080/mshare/3/30002:12:primary/stream_xNKNVH.mpeg" ; char *returnString; struct curl_slist *headers = NULL; ctx = curl_easy_init(); headers = curl_slist_append(headers,"Accept: */*"); headers = curl_slist_append(headers,"User-Agent: Kreatel_IP-STB");\ headers = curl_slist_append(headers,"getcontentFeatures.dlna.org: 1"); headers = curl_slist_append(headers,"Pragma:"); headers = curl_slist_append(headers,"Proxy-Connection:"); curl_easy_setopt(ctx,CURLOPT_HTTPHEADER , headers ); curl_easy_setopt(ctx,CURLOPT_NOBODY ,1 ); curl_easy_setopt(ctx,CURLOPT_VERBOSE, 1); curl_easy_setopt(ctx,CURLOPT_URL,url ); curl_easy_setopt(ctx,CURLOPT_NOPROGRESS ,1 ); curl_easy_perform(ctx); curl_easy_cleanup(ctx); curl_global_cleanup(); The code shown above sends the HEAD Request in slightly different form (shown below) HEAD http://192.168.70.1:8080/mshare/3/30002:12:primary/stream_xNKNVH.mpeg HTTP/1.1 Host: 192.168.70.1:8080 Proxy-Connection: Keep-Alive Accept: */* User-Agent: Kreatel_IP-STB getcontentFeatures.dlna.org: 1 Can any one , share the appropriate code ?

  • Does a hidden UIViewController consume any resources (iPhone)?

    - by MrDatabase
    My simple iPhone game has two basic "screens": home screen (UIViewController subclass) game screen (UIWindow w/ EAGLLayer where all the OpenGL drawing happens) Currently when the user taps "Play" on the homescreen the UIViewController is just hidden and the game screen is revealed. When the game is over the homescreen UIViewController is unhidden. Does the hidden UIViewController consume any resources when it's hidden?

  • How do I set selection to Nothing when programming Excel using VBA?

    - by Curt
    When I create a graph after using range.copy and range.paste it leaves the paste range selected, and then when I create a graph a few lines later, it uses the selection as the first series in the plot. I can delete the series, but is there a more elegant way to do this? I tried Set selection = nothing but it won't let me set selection. I also tried selection.clear, but that just cleared the last cells that were selected, and still added an extra series to the plot. Curt

  • feedback for programming newbies looking to build a social networking site?

    - by kgardnr
    my partner and i are launching a social learning platform - the requirements have been mapped out and are quite basic/intuitive. we are familiar with html/css, and have some very basic understanding of php, but we would love some feedback on whether we should tackle this ourselves or not. we've built websites, but in the past relied mostly on pre-fab code, i.e. wordpress, ning, etc. we've been looking specifically at ruby for developing the network, but i haven't delved into it fully yet. we're looking for some guidance and feedback - e.g. thoughts on ruby on rails? what's the learning curve? are we getting in over our heads? thanks in advance!

  • Why does using the Asynchronous Programming Model in .Net not lead to StackOverflow exceptions?

    - by uriDium
    For example, we call BeginReceive and have the callback method that BeginReceive executes when it has completed. If that callback method once again calls BeginReceive in my mind it would be very similar to recursion. How is that this does not cause a stackoverflow exception. Example code from MSDN: private static void Receive(Socket client) { try { // Create the state object. StateObject state = new StateObject(); state.workSocket = client; // Begin receiving the data from the remote device. client.BeginReceive( state.buffer, 0, StateObject.BufferSize, 0, new AsyncCallback(ReceiveCallback), state); } catch (Exception e) { Console.WriteLine(e.ToString()); } } private static void ReceiveCallback( IAsyncResult ar ) { try { // Retrieve the state object and the client socket // from the asynchronous state object. StateObject state = (StateObject) ar.AsyncState; Socket client = state.workSocket; // Read data from the remote device. int bytesRead = client.EndReceive(ar); if (bytesRead > 0) { // There might be more data, so store the data received so far. state.sb.Append(Encoding.ASCII.GetString(state.buffer,0,bytesRead)); // Get the rest of the data. client.BeginReceive(state.buffer,0,StateObject.BufferSize,0, new AsyncCallback(ReceiveCallback), state); } else { // All the data has arrived; put it in response. if (state.sb.Length > 1) { response = state.sb.ToString(); } // Signal that all bytes have been received. receiveDone.Set(); } } catch (Exception e) { Console.WriteLine(e.ToString()); } }
