  • Detecting I/O errors in a NON BLOCKING SOCKET

    - by ripunjay-tripathi-gmail-com
    I am writing a client - server system in which I used NON-BLOCKING sockets. My problem is to detect error { while performing send() or write() } that may occur while data transfer. Example lets say, while the data is being transferred the peer crashes. Another case there is some network problem, something like wire unplugged etc. As of now, I am using a high level ACK, that peer sends after receiving the complete data. Ripunjay Tripathi

  • Is it possible to filter users from a launchd plist?

    - by compriots
    I have some launchd plists that are now placed at the administrator per-user level, particularly inside: - /Library/LaunchAgents OR - /Library/LaunchDaemons I'd like to avoid that some of those services could start only for one user (possibly avoiding to move all the plists to ~/Library/LaunchAgents), which is the simplest way? Thanks in advance.

    - by DanSogaard
    When you go to Lists, and Create. I'd like to show the "Custom Lists" column only to specific group.

  • iPhone Application Deploy without using iTunes

    - by Paulo Correia
    I want to build an application for the iPhone to be used inside a customer enterprise (very small, only 5 to 10 devices). But since they will be paying the application development, I don't want to distribute that application to the world inside the App Store in iTunes. How can I distribute this app to my customer? Should I get the Enterprise level subscription from the Apple Developer Program? Since I work as a freelancer, I think I can't subscribe to that program.

  • Financial Charts / Graphs in Ruby or Python

    - by Eric the Red
    What are my best options for creating a financial open-high-low-close (OHLC) chart in a high level language like Ruby or Python? While there seem to be a lot of options for graphing, I haven't seen any gems or eggs with this kind of chart. http://en.wikipedia.org/wiki/Open-high-low-close_chart (but I don't need the moving average or Bollinger bands) JFreeChart can do this in Java, but I'd like to make my codebase as small and simple as possible. Thanks!

  • Can't get InputStream read to block...

    - by mark dufresne
    I would like the input stream read to block instead of reading end of stream (-1). Is there a way to configure the stream to do this? Here's my Servlet code: PrintWriter out = response.getWriter(); BufferedReader in = request.getReader(); try { String line; int loop = 0; while (loop < 20) { line = in.readLine(); lgr.log(Level.INFO, line); out.println("<" + loop + "html>"); Thread.sleep(1000); loop++; // } } catch (InterruptedException ex) { lgr.log(Level.SEVERE, null, ex); } finally { out.close(); } Here's my Midlet code: private HttpConnection conn; InputStream is; OutputStream os; private boolean exit = false; public void run() { String url = "http://localhost:8080/WebApplication2/NewServlet"; try { conn = (HttpConnection) Connector.open(url); is = conn.openInputStream(); os = conn.openOutputStream(); StringBuffer sb = new StringBuffer(); int c; while (!exit) { os.write("<html>\n".getBytes()); while ((c = is.read()) != -1) { sb.append((char) c); } System.out.println(sb.toString()); sb.delete(0, sb.length() - 1); try { Thread.sleep(1000); } catch (InterruptedException ex) { ex.printStackTrace(); } } os.close(); is.close(); conn.close(); } catch (IOException ex) { ex.printStackTrace(); } } I've tried InputStream.read, but it doesn't block either, it returns -1 as well. I'm trying to keep the I/O streams on either side alive. I want the servlet to wait for input, process the input, then send back a response. In the code above it should do this 20 times. thanks for any help

  • Can Goldberg algorithm in ocamlgraph be used to find Minimum Cost Flow graph?

    - by Tautrimas
    I'm looking for an implementation to the Minimum Cost Flow graph problem in OCaml. OCaml library ocamlgraph has Goldberg algorithm implementation. The paper called Efficient implementation of the Goldberg-Tarjan minimum-cost flow algorithm is noting that Goldberg-Tarjan algorithm can find minimum cost graph. Question is, does ocamlgraph algorithm also find the minimum cost? Library documentation only states, that it's suitable at least for the maximum flow problem. If not, does anybody have a good link to a nice any minimum cost optimization algorithm code? I will manually translate it into OCaml then. Forgive me, if I missed it on Wikipedia: there are too many algos on flow networks for the first day!

  • How do I change a file's path in git's history?

    - by carleeto
    Here is what I have - a git repo of my code: projects |-proj1 (no git repo here yet) |-subproj1 <- current git repo here Here is what I want - a git repo which is now tracking a new project that uses my code: projects |-proj1 <-git repo moved to here, but still tracking files in subproj1 |-subproj1 (no git repo here) I'd like to keep the history intact and therefore the new repository will be referring to files that are one level deeper than the original. What is the most pain free way to do this?

  • Why should I reuse XmlHttpRequest objects?

    - by Xavi
    From what I understand, it's a best practice to reuse XmlHttpRequest objects whenever possible. Unfortunately, I'm having a hard time understanding why. It seems like trying to reuse XHR objects can increase code complexity, introduce possible browser incompatibilities, and lead to other subtle bugs. After researching this question for a while, I did come up with a list of possible explanations: Fewer objects created means less garbage collecting Reusing XHR objects reduces the chance of memory leaks The overhead of creating a new XHR object is high The browser is able to perform some sort of network optimization under hood But I'm not sure if any of these reasons are actually valid. Any light you can shed on this question would be much appreciated.

  • WPF Textbox Preview events related

    - by Nitin Chaudhari
    I have a WPF textbox, and perform the following actions Enter text as "12345" Move cursor between 3 and 4 (using arrow or mouseclick) Enter 0 (so Text is now "123045") Which event/eventargs can tell me that 0 was typed at location 4. I need to know this at Preview level so that I can reject the character 0 based on the prefixed and suffixed digits.

  • How to catch an exception and email information about it in liferay portlet

    - by heikkim
    I have a custom portlet made for liferay and sometimes it throws an exception. Why it throws exceptions is irrelevant. How to catch exceptions thrown by portlet handler methods in order to email information about them? I know I could do try catching on every handler method but it would be a much more elegant and cleaner solution to catch the exception on a higher level and just email some information about the error. I'm using Spring Portlet MVC, so i got all spring-related niceties at hand.

  • WinForms: How to prevent textbox from opening alt menu?

    - by Digiku
    I have this textbox I use to capture keyboard shortcuts for a preferences config. I use a low-level keyboard hook to capture keys and also prevent them from taking action, e.g. the Windows key, but the Alt key still comes through and makes my textbox lose focus. How can I block the Alt key, so the focus is kept unaltered at my textbox?

  • Python / Django : emulating a multidimensional layer on a MySQL database

    - by Sébastien Piquemal
    Hi, I'm working on a Django project where I need to provide a lot of different visualizations on the same data (for example average of a value for each month, for each year / for a location, etc...). I have been using an OLAP database once in college, and I thought that it would fit my needs, but it appears that it is much too heavy for what I need. Actually the volume of data is not very big, so I don't need any optimization, just a way to present different visualizations of the same data without having to write 1000 times the same code. So, to recap, I need a python library: to emulate a multidimensional database (OLAP style would be nice because I think it is quite convenient : star structure, and everything) non-intrusive, because I can't modify anything on the existing MySQL database easy-to-use, because otherwise there's no point in replacing some overhead by another.

  • How bad is it to use a virtual file system with VMWare? [closed]

    - by user30997
    IT is running a series of VMs that we'd like to see optimized further: if the VMs' are Windows XP, storing their NTFS images out to the virtual disk (ext3) provided by Linux/VMWare, how much of a hit are we taking - as opposed to having a partition of the host hard drive formatted NTFS to eliminate the translation layer and the extra level of operating system IO preparation?

  • How can I demonstrate the benefits of abstractions to an old-time C programmer?

    - by Zaban Khuli
    Hi, there's this senior developer in my company that programs in C. I happen to be from functional background (ML, to be specific). This senior C programmer refuses to use abstractions because "abstraction is for lame programmers and _real_ programmers do not need it." I can not seem to convince him otherwise Is it a problem with only this programmer or do all C (and other lower level language) programmers have this opinion that abstraction is for lame programmers?
