  • Java : method to to print relative pathname?

    - by HH
    I am hesitant just to look at some env.vars and try to replace things with regexes. So is there a ready method to print relative pathnames system-independently? $ echo ~ /u/user $ pwd /u/user/OH/one/src $ echo "Like relative pathnames ~/OH/one/src, not /u/user/OH/one/src."

  • Pretty-printing of numpy.array

    - by camillio
    Hello, I'm curious, whether there is any way to print formated numpy.arrays, e.g., in the way similar to this: x = 1.23456 print '%.3f' % x If I want to print the numpy.array of floats, it prints several decimals, often in 'scientific' format, which is rather hard to read even for low-dimensional arrays. However, numpy.array apparently has to be printed as a string, i.e., with %s. Is there any solution ready for this purpose? Many thanks in advance :-)

  • Zend Server experiences

    - by Luke
    The other day I was looking into Zend Server and I was wondering why I would use this? OK, they say it's all tested and mission critical and Enterprise ready etc. But to me that's just the marketing department talking. Is anyone out there using this product and if so can you share your experiences with it and maybe you could also elaborate on the reason on why you choose this product for your application(s). Did you find any real benefits to using Zend server?

    - by Steven
    Hi all, We're developing a saas app, which is almost finished. Being in the final stages we're wondering how we are going to charge customers for using our app, how we will enforce they will not pass on their logins and so on. Does anyone know a ready-made solution? We do have a budget for this. rough criteria: - enforcing multiple payment/licensing options (trial - license with grace periods, on demand, pay per use, etc) - integration with payment providers - tracking/preventing unauthorised usage - payment/license plans adjustable on a per customer(group) basis

  • jquery live tabIndex

    - by VictorS
    I have a jQuery statement that's working fine. How would I re-write it in .live? $(document).ready(function() { $(':input:enabled:visible, a:enabled:visible, span.ValidatorClass').each (function(i, e) { $(e).attr('tabindex', i) }); }); The reason I need this is that I am doing .show and .hide sometimes and need to reset tab order when that happens for the elements that appear.

  • How do you reference a custom object outside of the function it was created in with JavaScript?

    - by Jack Roscoe
    Hi, I'm currently using JavaScript and jQuery. I have an function which executes once the document is ready, and inside that I am creating objects which contain various attributes. Within the same function, I can access these new object's attributes no problem, however once I'm inside a different function I can't seem to reference them properly and therefore cannot access the objects or the information inside them. What's the correct way to reference the attributes of an object which was created in a different function to the one looking for the information?

  • HipHop instead of XCache?

    - by Marco
    Would it make sense to switch to HipHop to replace XCache? It seems illogical to run both simultaneously. Is HipHop ready for primetime or should we wait several months before implementing it?

  • 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

  • How to get jQuery to work with Prototype

    - by thinkfuture
    Ok so here is the situation. Been pulling my hair out on this one. I'm a noob at this. Only been using rails for about 6 weeks. I'm using the standard setup package, and my code leverages prototype helpers heavily. Like I said, noob ;) So I'm trying to put in some jQuery effects, like PrettyPhoto. But what happens is that when the page is first loaded, PrettyPhoto works great. However, once someone uses a Prototype helper, like a link created with link_to_remote, Prettyphoto stops working. I've tried jRails, all of the fixes proposed on the JQuery site to stop conflicts... http://docs.jquery.com/Using_jQuery_with_Other_Libraries ...even done some crazy things likes renaming all of the $ in prototype.js to $$$ to no avail. Either the prototype helpers break, or jQuery breaks. Seems nothing I do can get these to work together. Any ideas? Here is part of my application.html.erb <%= javascript_include_tag 'application' %> <%= javascript_include_tag 'tooltip' %> <%= javascript_include_tag 'jquery' %> <%= javascript_include_tag 'jquery-ui' %> <%= javascript_include_tag "jquery.prettyPhoto" %> <%= javascript_include_tag 'prototype' %> <%= javascript_include_tag 'scriptalicious' %> </head> <body> <script type="text/javascript" charset="utf-8"> jQuery(document).ready( function() { jQuery("a[rel^='prettyPhoto']").prettyPhoto(); }); </script> If I put prototype before jquery, the prototype helpers don't work If I put the noconflict clause in, neither works. Thanks in advance! Chris BTW: when I try this, from the jQuery site: <script> jQuery.noConflict(); // Use jQuery via jQuery(...) jQuery(document).ready(function(){ jQuery("div").hide(); }); // Use Prototype with $(...), etc. $('someid').hide(); </script> my page disappears!

  • Strategy for converting a VB6 app to .NET

    - by Craig Johnston
    Would it be a good idea to start converting forms into .NET one at a time which you would then invoke from the VB6 app via COM-interop. This way, by the end of the process you would just convert the 'shell' of the VB6 application into a new .NET app, and all your forms are ready to go in .NET. Is there a better strategy?

  • Hibernate CRUD à la Ruby on Rails' Scaffolding

    - by schonarth
    Guys, Do you know of any tool that would do like Ruby on Rails' Scaffolding (create simple CRUD pages for any particular class to allow quickly populating a database with dummy data), only which used Java classes with Hibernate for database access, and JSP/JSF for the pages? It is a drag when you are programming one part of an application, but need data that can only be added with another part that is not ready yet, or very cumbersomely by directly inserting it into the DB.
