  • Best Cross Platform Networking Framework For iPhone Dev

    - by Carmen
    I am looking to write a client/server application that will run on both iPhone, OS X and Windows. What are the best solutions for networking that will work on all 3 platforms? I have looked into Qt and it doesn't look like it has support for iPhone. I have also looked at boost, and that looks like it can be compiled for the iPhone. However I was hoping for a somewhat higher level framework like what Qt has to offer.

  • Java: Send BufferedImage through Socket with a low bitdepth

    - by Martijn Courteaux
    Hi, The title says enough I think. I have a full quality BufferedImage and I want to send it through an OutputStream with a low bitdepth. I don't want an algorithm to change pixel by pixel the quality, so it is still a full-quality. So, the goal is to write the image (with the full resolution) through the OuputStream with a very small size. Thanks, Martijn

  • How to create a Turing machine that takes a single digit decimal number from 0 - 9 and output the cu

    - by Julian
    I'm working on a project for a Turning machine but having problems conceptualizing the steps. f(x) = x^3, where x is a single digit between 0 - 9 inclusive. Based on my understanding I am to convert the number to binary but how do I find the cube of a number in binary. Also, how do I write the cube on the tape. So far I'm thinking I should create a state diagram that accepts the binary versions of 0-9 but what next?

  • Difference between Java SE/EE/ME?

    - by Richard Knop
    Which one should I install when I want to start learning Java? I going to start with some basics so I will create simple programs that create files, directories, edit XML files and so on, nothing too complex for now. I guess Java SE (Standard Edition) is the one I should install on my Windows 7 desktop? I already have Komodo IDE which I will use to write Java code.

  • Find and replace in a block of text.

    - by David Tildon
    I have a database full of text fields that look like this: (paragraph of normal text) image:blog/clownboy.jpg (another paragraph) I'm trying to write a view helper for Rails that will take one of these big blocks of text, find bits like "image:blog/clownboy.jpg" and replace them with the corresponding <img src="blog/clownboy.jpg"> (without disturbing the surrounding whitespace) before outputting it to the user. I've been trying for an hour or so now, but I'm new to Ruby and the regular expressions are still a bit beyond me.

  • Is redis a durable datastore?

    - by allyourcode
    By "durable" I mean, the server can crash at any time, and as long as the disk remains in tact, no data is lost (see ACID). Seems like that's what journaling mode is for, but if you enable journaling, doesn't that defeat the purpose of operating on in-memory data? Read operations might not be affected by journaling, but it seems like journaling would kill your write performance.

  • How do I mock an object in this case? no obvious way to replace object with mock

    - by Tristan
    Hi there, Suppose I have this very simple method in Store's model: def geocode_address loc = Store.geocode(address) self.lat = loc.lat self.lng = loc.lng end If I want to write some test scripts that aren't affected by the geocoding service, which may be down, have limitations or depend on my internet connection, how do I mock out the geocoding service? If I could pass a geocoding object into the method, it would be easy, but I don't see how I could do it in this case. Thanks! Tristan

  • System.IO.IOException: file used by another process

    - by Srodriguez
    Dear all, I've been working in this small piece of code that seems trivial but still i cannot really see where is the problem. My functions does a pretty simple thing. Opens a file, copy its contents, replace a string inside and copy it back to the original file (a simple search and replace inside a text file then). I didn't really know how to do that as I'm adding lines to the original file, so i just create a copy of the file, (file.temp) copy also a backup (file.temp) then delete the original file(file) and copy the file.temp to file. I get an exception while doing the delete of the file. Here is the sample code: private static bool modifyFile(FileInfo file, string extractedMethod, string modifiedMethod) { Boolean result = false; FileStream fs = new FileStream(file.FullName + ".tmp", FileMode.Create, FileAccess.Write); StreamWriter sw = new StreamWriter(fs); StreamReader streamreader = file.OpenText(); String originalPath = file.FullName; string input = streamreader.ReadToEnd(); Console.WriteLine("input : {0}", input); String tempString = input.Replace(extractedMethod, modifiedMethod); Console.WriteLine("replaced String {0}", tempString); try { sw.Write(tempString); sw.Flush(); sw.Close(); sw.Dispose(); fs.Close(); fs.Dispose(); streamreader.Close(); streamreader.Dispose(); File.Copy(originalPath, originalPath + ".old", true); FileInfo newFile = new FileInfo(originalPath + ".tmp"); File.Delete(originalPath); File.Copy(fs., originalPath, true); result = true; } catch (Exception ex) { Console.WriteLine(ex); } return result; }` And the related exception System.IO.IOException: The process cannot access the file 'E:\mypath\myFile.cs' because it is being used by another process. at System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath) at System.IO.File.Delete(String path) at callingMethod.modifyFile(FileInfo file, String extractedMethod, String modifiedMethod) Normally these errors come from unclosed file streams, but I've taken care of that. I guess I've forgotten an important step but cannot figure out where. Thank you very much for your help,
