  • Is a server an infinite loop running as a background process?

    - by Tony
    Is a server essentially a background process running an infinite loop listening on a port? For example: while(1){ command = read(127.0.0.1:xxxx); if(command){ execute(command); } } When I say server, I obviously am not referring to a physical server (computer). I am referring to a MySQL server, or Apache, etc. Full disclosure - I haven't had time to poke through any source code. Actual code examples would be great!

    The following snippet is from a little console app I wrote using the QT framework. Currently, it does not receive the arguments passed at the CLI.

  • Indexing one-dimensional numpy.array as matrix

    - by Alain
    I am trying to index a numpy.array with varying dimensions during runtime. To retrieve e.g. the first row of a n*m array a, you can simply do a[0,:] However, in case a happens to be a 1xn vector, this code above returns an index error: IndexError: too many indices As the code needs to be executed as efficiently as possible I don't want to introduce an if statement. Does anybody have a convenient solution that ideally doesn't involve changing any data structure types?

  • Neat way of calling InvokeRequired and Invoke

    I seem to remember seeing some neat way of calling InvokeRequired and Invoke to avoid repeating too much code in every event handler but I can't remember what that was. So does anyone know a neat way of writing that code? Preferably for VB.Net 2005.

  • C# recursive programming with lists

    - by David Torrey
    I am working on a program where each item can hold an array of items (i'm making a menu, which has a tree-like structure) currently i have the items as a list, instead of an array, but I don't feel like I'm using it to its full potential to simplify code. I chose a list over a standard array because the interface (.add, .remove, etc...) makes a lot of sense. I have code to search through the structure and return the path of the name (i.e. Item.subitem.subsubitem.subsubsubitem). Below is my code: public class Item { //public Item[] subitem; <-- Array of Items public List<Item> subitem; // <-- List of Items public Color itemColor = Color.FromArgb(50,50,200); public Rectangle itemSize = new Rectangle(0,0,64,64); public Bitmap itemBitmap = null; public string itemName; public string LocateItem(string searchName) { string tItemName = null; //if the item name matches the search parameter, send it up) if (itemName == searchName) { return itemName; } if (subitem != null) { //spiral down a level foreach (Item tSearchItem in subitem) { tItemName = tSearchItem.LocateItem(searchName); if (tItemName != null) break; //exit for if item was found } } //do name logic (use index numbers) //if LocateItem of the subitems returned nothing and the current item is not a match, return null (not found) if (tItemName == null && itemName != searchName) { return null; } //if it's not the item being searched for and the search item was found, change the string and return it up if (tItemName != null && itemName != searchName) { tItemName.Insert(0, itemName + "."); //insert the parent name on the left --> TopItem.SubItem.SubSubItem.SubSubSubItem return tItemName; } //default not found return null; } } My question is if there is an easier way to do this with lists? I've been going back and forth in my head as to whether I should use lists or just an array. The only reason I have a list is so that I don't have to make code to resize the array each time I add or remove an item.

  • After Repo sync, there are no files int he directory.

    - by taranfx
    I've setup a new Repo for Android source code, and after executing the repo sync, there are no files in the repo directory. Did I miss something? I used: repo init -u git://android.git.kernel.org/platform/manifest.git repo initialized in /home/tarandeep/code/Android repo sync ... It downloaded GBs of data (I can confirm via network monitor) and then nothing appeared in the Android directory.

  • Simple Sinatra Ajax Not Working

    - by proteantech
    I was trying make an AJAX call from a static file on my computer to a simple sinatra service. The ajax call was returning with an error and no details. The server logged no errors either. Another strange symptom was that the Origin in the request header was null. I turns out that you can't make cross domain ajax calls without a little extra effort. You can set the Access-Control-Allow-Origin header on your sinatra response to expose your service to external domains using a snippet like this: get '/hi' do response['Access-Control-Allow-Origin'] = '*' content_type 'text/plain' "Hello World" end There's also another header you can set to allow other HTTP Methods besides gets, Access-Control-Request-Method. You can find more information by searching around for CORS: Cross Origin Resource Sharing and the previously mentioned headers. Oh, and in case you want to do this in Rails as well you can do something like this in your controller: after_filter :set_access_control_headers def set_access_control_headers headers['Access-Control-Allow-Origin'] = '*' headers['Access-Control-Request-Method'] = '*' end

    Hi, I am developing an iPhone app in which I want to set the keywords for an image using ImageIO.framework. Following is the code snippet that I use for setting the keywords. But, it does not apply the keywords to image meta data. Could some one help me out in finding the problem here. NSMutableDictionary *iptcDictionary = [NSDictionary dictionaryWithObject: [NSArray arrayWithObject: @"Test"] forKey:(NSString *)kCGImagePropertyIPTCKeywords]; NSDictionary *newImageProperties = [NSDictionary dictionaryWithObject:iptcDictionary forKey:(NSString *)kCGImagePropertyIPTCDictionary]; CGImageSourceRef imageSource=CGImageSourceCreateWithURL((CFURLRef)imageURL, nil); //imageURL is URL of source image CGImageDestinationRef imageDestination = CGImageDestinationCreateWithData( (CFMutableDataRef)newImageFileData, CGImageSourceGetType(imageSource), 1,NULL); CGImageDestinationAddImageFromSource(imageDestination, imageSource, 0, (CFDictionaryRef) newImageProperties); if (CGImageDestinationFinalize(imageDestination)) [newImageFileData writeToFile:imagePath atomically:YES]; //imagePath is the path of the destination image with new metadata Thanks and regards, Deepa

  • RESTful Http DELETE method in .NET

    - by VIBA
    I am new to web services. I am dealing with testing APIs in my project. In the previous version the company used GET and POST methods but not PUT and DELETE methods. I need help for the HTTP DELETE method. I have browsed various websites where I found the example code snippets for GET and POST methods, but not for DELETE and PUT methods (why?). Can anyone give me an example code snippet (C#) for RESTful HTTP DELETE method and explain how to call the DELETE request?

  • Script-Based Configuration in .net?

    - by Michael Stum
    One of the downsides of web.config/app.config is that it's just Magic Strings everywhere, since it's just an XML file. Interpreted languages like PHP or Ruby have the advantage that the configuration is just code that is executed. In .net, doing stuff in code requires a redeployment, which defeats the purpose. Now, before I build my own web.config replacement based on Boo or PowerShell I wanted to know if there is an existing one?

  • What is the best way to inject a javascript script from another domain into a page? (without using a

    - by lowellk
    Here is a snippet of javascript for loading a script onto a given page asynchronously. I was wondering if there was anything wrong with it? Can it be improved? I haven't played with this yet, but some things I'm worried about are: - cross browser support - when script.readyState is true, will the old version of that function get clobbered? - can i always count on there being a head or body element? Here it is: function injectScript(url, callback){ var script = document.createElement('script'); script.type = "text/javascript"; script.setAttribute('async', 'true'); script.src = url; (document.getElementsByTagName('head')[0] || document.getElementsByTagName('body')[0]).appendChild(script); if (callback) { if (script.readyState){ script.onreadystatechange = function(){ if(script.readyState === "loaded" || script.readyState === "complete"){ script.onreadystatechange = null; callback(); } }; }else{ script.onload = function() { callback(); } } } }

  • Is a string formatter that pulls variables from its calling scope bad practice?

    - by Eric
    I have some code that does an awful lot of string formatting, Often, I end up with code along the lines of: "...".format(x=x, y=y, z=z, foo=foo, ...) Where I'm trying to interpolate a large number of variables into a large string. Is there a good reason not to write a function like this that uses the inspect module to find variables to interpolate? import inspect def interpolate(s): return s.format(**inspect.currentframe().f_back.f_locals) def generateTheString(x): y = foo(x) z = x + y # more calculations go here return interpolate("{x}, {y}, {z}")
