  • New functional languages

    - by AnnaR
    Functional programming has been around since at least 1958 (creation of Lisp), but is experiencing a renaissance now with old functional languages being dusted off and new functional languages being created. Which functional languages are there that are newly developed or are in the making? I realize that you can write purely functional programs in most high level languages, so with functional languages I imply languages that are specifically designed for functional programming such as F#. If you have links to tutorials, wikis or code examples I encourage you to add them to your answer!

  • How Can I create different selectors for accepting new connection in java NIO

    - by Deepak
    I want to write java tcp socket programming using java NIO. Its working fine. But I am using the same selector for accepting reading from and writing to the clients. How Can I create different selectors for accepting new connection in java NIO, reading and writing. Is there any online help. Actually when I am busy in reading or writing my selector uses more iterator. So If more number of clients are connected then performance of accepting new coneection became slow. But I donot want the accepting clients to be slow // Create a selector and register two socket channels Selector selector = null; try { // Create the selector selector = Selector.open(); // Create two non-blocking sockets. This method is implemented in // e173 Creating a Non-Blocking Socket. SocketChannel sChannel1 = createSocketChannel("hostname.com", 80); SocketChannel sChannel2 = createSocketChannel("hostname.com", 80); // Register the channel with selector, listening for all events sChannel1.register(selector, sChannel1.validOps()); sChannel2.register(selector, sChannel1.validOps()); } catch (IOException e) { } // Wait for events while (true) { try { // Wait for an event selector.select(); } catch (IOException e) { // Handle error with selector break; } // Get list of selection keys with pending events Iterator it = selector.selectedKeys().iterator(); // Process each key at a time while (it.hasNext()) { // Get the selection key SelectionKey selKey = (SelectionKey)it.next(); // Remove it from the list to indicate that it is being processed it.remove(); try { processSelectionKey(selKey); } catch (IOException e) { // Handle error with channel and unregister selKey.cancel(); } } } public void processSelectionKey(SelectionKey selKey) throws IOException { // Since the ready operations are cumulative, // need to check readiness for each operation if (selKey.isValid() && selKey.isConnectable()) { // Get channel with connection request SocketChannel sChannel = (SocketChannel)selKey.channel(); boolean success = sChannel.finishConnect(); if (!success) { // An error occurred; handle it // Unregister the channel with this selector selKey.cancel(); } } if (selKey.isValid() && selKey.isReadable()) { // Get channel with bytes to read SocketChannel sChannel = (SocketChannel)selKey.channel(); // See e174 Reading from a SocketChannel } if (selKey.isValid() && selKey.isWritable()) { // Get channel that's ready for more bytes SocketChannel sChannel = (SocketChannel)selKey.channel(); } } Thanks Deepak

  • HTTP New location after download starts

    - by Flavius
    Hi I'm using X-Accel-Redirect (so implicitly nginx), Content-Type and Content-Disposition to download a file, everything works great. What I need to accomplish is redirecting to a new location after the download starts. I've tested with both Refresh and Location, it doesn't work. Is it possible with HTTP 1.1/nginx?

  • IE8 Debugger: how to load external javascript files?

    - by Chris Barnhill
    I have downloaded and installed IE8. I was playing around with the debugger, but I could not figure out how to load external javascript files. It displays the javascript from the main page, but I need to debug the script in the external files. I have googled various articles that show a screenshot of an IE8 debugger with a drop-down for selecting which script to debug, but my debugger does not feature this. Can anyone help me with this? Thanks.

  • What task can I automate in Python that's fun, simple, and useful?

    - by froadie
    I'm trying to learn Python. I'm going to eventually be using it at work, but I don't have an active project in it as of now. I've been reading through some documentation and would like to learn some basics, but I learn best when actually coding. So I'm thinking of attempting a small Python project just to sort of "get my feet wet" in Python. While reading/asking around, I've often heard people say that if you need a Python project you should automate some task you do on your computer on a day-to-day basis. Maybe I'm not so imaginative, but I can't think of anything I'd like to automate... Does anyone have any ideas of something simple, fun, and not too time-consuming that someone can automate to get some basic experience in Python? Something that they would come out of feeling like they accomplished something fun and useful?

  • ASP.net Error in Design Mode

    - by stringo0
    I just switched to VS 2010, and upgraded a previous project. I'm getting the following error on a page in design mode for 2 controls: Error Creating Control - ObjectName Object reference not set to an instance of an object. One of them is a simple label, and the other is a ajax update panel. Other pages look fine. When I build and test the app, the page renders fine in the browser and functions fine - the label functions as expected and the content in the update panel works as expected. Any ideas why I'm getting this error? I tried some of the google results to no avail. It'd be great to get this out of the way. Thanks!

  • How can I let prospective employers know I'm a great developer?

    - by Zoe Gagnon
    I've recently read through Joel's guide to finding great developers (http://www.joelonsoftware.com/articles/FindingGreatDevelopers.html), and I feel really strongly that I am smart and get things done. The problem is, I didn't learn how to get things done until about halfway through college, so my GPA is less than stellar. Additionally, I've got a few other things going against me: late into the job market (~30), no internship, state college instead of university, and when I graduated, I pretty much had to take the first job that offered. With all of these things piled together, my resume (the first step to getting a job), is not terribly impressive. What can I do to let people know that I'm a great developer and would complement the best companies in the world?

    I'm using the new API to set the width of my jqGrid like this: $('#grid').jqGrid('setGridWidth', $(window).width() * 0.98); The problem is that in IE7 I'm getting this error: 'p.cellLayout' is null or not an object This only happens in IE7 (IE8, Firefox and Chrome work fine). Has anybody else encounter this problem and fixed it?

  • In the future, when mobile devices are embedded in your body, what kind of APIs might be availbe to an application developer?

    - by Conor
    Mobile devices have APIs that allow an application to send and receive SMS, make a phone call, determine location etc. In the future, when mobile devices are embedded in your body, what kind of APIs might be availbe to an application developer? EDIT: This is not intended to be a joke question (but what's the harm in some funny answers?). It's to spur a discussion on how one aspect of mobile device application could pan out and what kind of application might be available. For example: health monitoring - various APIs available to get body temperature, sugar levels, etc for transmission to your GP.

  • += new EventHandler(Method) vs += Method

    - by mafutrct
    There are two basic ways to subscribe to an event: SomeEvent += new EventHandler<ArgType> (MyHandlerMethod); SomeEvent += MyHandlerMethod; What is the difference, and when should I chose one over the other? Edit: If it is the same, then why does VS default to the long version, cluttering the code? That makes no sense at all to me.

  • NetBeans Java code formatter: logical operators on new line

    - by mizipzor
    My code looks like this: if (firstCondition() && secondCondition()) { // ... code } The default settings for the code formatter in NetBeans wants to put the && on a new line, like this: if (firstCondition() && secondCondition()) { // ... code } The formatter works well so I would just like to find the setting so it doesnt change the code to the latter. Whats the setting called?
