  • Connecting 2 PCs using USB-to-USB (male-male) cable

    - by Amirizzuan
    I found this while Googling around: http://www.hardwaresecrets.com/article/Connecting-Two-PCs-Using-a-USB-USB-Cable/248 But then, the solution given in the article is using Windows. Is there any Ubuntu equivalent to this? I would really love to SSH into my Ubuntu server via my Ubuntu laptop, just by connecting one end of the male USB to my laptop, and another end of the male USB to my server. I know I can always SSH into my server via the network, but then in this case of mine, there are cases the server is inside a secluded-secured network server room, and the only way for me to check things out is to go into the server room and open the keyboard console and monitor there. But, if I can just bring my laptop inside and connect to the USB there, then that would be cool. Any idea guys?

  • Get Lit

    - by T
    I keep meaning to post some technical blog posts.  I have the ideas stacked up but get distracted with side projects like this latest one http://getlit.eventbrite.com .  This is going to be awesome fun!  It is a hands-on event to work though a Silverlight project from start to finish.  The project will allow you to take netflix data and store it in a personal catalog of movies.  It isn’t exactly useful but it is designed to have data from multiple sources (O’Data and SQL using RIA and MVVM) and different UI aspects for some cool templating practice and custom build behaviors. Sign up soon.  Space is limited! http://getlit.eventbrite.com

  • Is it possible to expose data from Oracle using OData?

    - by Michael Rosario
    From my personal research, it appears that OData implementations depend extensively on MS Entity framework. It would seem possible to implement the OData producer protocol using an open ORM like NHibernate in C# or Hibernate in Java. In the best of all worlds, it would be cool to expose data using OData protocol from Oracle. I am open to other open solutions like Java, JRuby, etc. Thanks in advance for your time.

  • Computer science undergraduate project ideas

    - by Mehrdad Afshari
    Hopefully, I'm going to finish my undergraduate studies next semester and I'm thinking about the topic of my final project. And yes, I've read the questions with duplicate title. I'm asking this from a bit different viewpoint, so it's not an exact dupe. I've spent at least half of my life coding stuff in different languages and frameworks so I'm not looking at this project as a way to learn much about coding and preparing for real world apps or such. I've done lots of those already. But since I have to do it to complete my degree, I felt I should spend my time doing something useful instead of throwing the whole thing out. I'm planning to make it an open source project or a hosted Web app (depending on the type) if I can make a high quality thing out of it, so I decided to ask StackOverflow what could make a useful project. Situation I've plenty of freedom about the topic. They also require 30-40 pages of text describing the project. I have the following points in mind (the more satisfied, the better): Something useful for software development Something that benefits the community Having academic value is great Shouldn't take more than a month of development (I know I'm lazy). Shouldn't be related to advanced theoretical stuff (soft computing, fuzzy logic, neural networks, ...). I've been a business-oriented software developer. It should be software oriented. While I love hacking microcontrollers and other fun embedded electronic things, I'm not really good at soldering and things like that. I'm leaning toward a Web application (think StackOverflow, PasteBin, NerdDinner, things like those). Technology It's probably going to be done in .NET (C#, F#) and Windows platform. If I really like the project (cool low level hacking), I might actually slip to C/C++. But really, C# is what I'm efficient at. Ideas Programming language, parsing and compiler related stuff: Designing a domain specific programming language and compiler Templating language compiled to C# or IL Database tools and related code generation stuff Web related technologies: ASP.NET MVC View engine doing something cool (don't know what exactly...) Specific-purpose, small, fast ASP.NET-based Web framework Applications: Visual Studio plugin to integrate with Bazaar (it's too much work, I think). ASP.NET based, jQuery-powered issue tracker (and possibly, project lifecycle management as a whole - poor man's TFS) Others: Something related to GPGPU Looking forward for great ideas! Unfortunately, I can't help on a currently existing project. I need to start my own to prevent further problems (as it's an undergrad project, nevertheless).

  • jQuery Horizontal Ticker with Continuous loop

    - by Dkong
    I am using a jQuery ticker which is pretty cool. It works well with predefined content, but I want to build my tags dynamically by getting the data from a feed via the $.ajax method. http://progadv.uuuq.com/jStockTicker/ The problem is when I do this the ticker wont work, as it looks like the function might be loading before my page content has loaded. Can anbody think of a way around this? $(function() { $("#ticker").jStockTicker({interval: 45}); });

  • Eye candy in OpenGL

    - by anon
    I'm interested in creating realtime visual special effects. I am limited to OpenGL (in particular, computing power of a MacBook Pro). I want to learn more about doing cool UI/special effects (think the "computers/displays" in Iron Man / Avatar). What are good books/resources for this? Thanks!

  • What groupware/collaboration system to choose?

    - by Ivan
    I am looking for a good (stable enough, intuitive enough, and the more technologically modern and advanced - the better) free PHP-based online groupware/collaboration system. 100% UTF-8 is a requirement. OOP-style code is an advantage. And collaborative mindmapping would be a cool feature to have. The team is of ~20 people. Any suggestions?

  • Jruby Gems-in-a-jar issue

    - by antonio
    Hi all, I am trying to write some code in ruby (using jruby) to be compiled to java bytecode with jrubyc and deployed to a remote machine where it will be run on the JVM (no ruby available there). Everything works fine as long as I am happy to stick with the standard jruby library. As explained on the jruby website, I simply copy the jruby-complete.jar library to the remote machine and include it in the classpath at runtime. I fire my compiled script and it works: cool! The problems start when I need some other libraries (typically rubygems) to run my script. I am aware of cool stuff like rawr, -which I successfully tested- to put together all you need in a single package. However that is not the solution I am looking for: I will have many small scripts to run independently and I don't want each of them to grow to at least 10 MB just because I insanely include the jruby-complete.jar in each of them. What I would like is to compile a .jar for each of the libraries that I will need to use, put all of them in a common folder on the remote machine and include them at runtime in the classpath when I run my compiled jruby scripts on the JVM. This said, I tried to follow the instructions here: http://blog.nicksieger.com/articles/2009/01/10/jruby-1-1-6-gems-in-a-jar I tried exactly the example shown there, with the "chronic" gem. Going step by step: Install the gem locally: java -jar jruby-complete-1.1.6.jar -S gem install -i ./chronic chronic --no-rdoc --no-ri Package it into a jar: jar cf chronic.jar -C chronic . Write a two lines test script, saving it as testt.rb: require 'chronic' Chronic.parse('tomorrow') Compile with: jrubyc testt.rb Run the resulting java class testt.class with the following (having both jruby-complete.jar and chronic.jar in the same folder as the java class): java -cp .:/jruby-complete.jar:./chronic.jar testt I get the following error: Exception in thread "main" file:/Users/ave2/NetBeansProjects/jrubywatir/lib/jruby-complete.jar!/METAINF/jruby.home/lib/ruby/site_ruby/shared/builtin/core_ext/symbol.rb:1:in `const_missing': uninitialized constant Chronic (NameError) from testt.rb:2 ...internal jruby stack elided... from Module.const_missing(testt.rb:2) from (unknown).(unknown)(:1) I really don't understand what I am doing wrong, and I am totally stuck on this. I am a noob in Ruby, much more used to Python: don't miss a chance to convert an infidel! :-) Thanks.

  • jQuery as a replacement for Django or Web2Py

    - by ganjod
    Hi all, I was planning to write a new webapp, I figured out two options for my backend - web2py or django. I recently came across jQuery and found it to be very cool. Could I just use jQuery as a replacement for django and web2py and finish this webapp. Some features that I'm going to implement - user profiles, users can add content to the website, etc. Is it possible to do solely in jQuery ?

  • Visual Studio T4 vs CodeSmith

    - by Jake
    I've been using CodeSmith for the past 2 years and love what it does for me. However, I also know about T4 which is built in to Visual Studio and can do some pretty cool stuff too. Based on conversations with friends T4 in VS2010 T4 is going to be even better. So the question is: do I keep riding the CodeSmith bus or is it time to start converting all of my templates to T4?

  • Breaking a concave polygon into convex ones.

    - by Bart van Heukelom
    I'm using a game physics library (Box2D) which only supports convex polygon shapes. However, I'd like the level builder to be able to just specify concave polygons without having to worry about that. So, how can I automatically break apart a concave polygon into convex ones (or even all triangles). Speed would be cool, but ease of implementation is more important. The breaking apart will only be done on game initialization. (My language is Flash/ActionScript 3, but that shouldn't matter)

  • How Do I Setup Multiple Stores Using Magento Like Their Demo?

    - by FergatROn
    I'm playing with Magento and I figured out how to create multiple websites and stores and store views, but when I go back to the home page it certainly doesn't look as cool as the Magento Demo (http://www.magento-mall.com/). Are the tabs something they did in the HTML and the store domains are really masking to the ugly store URL? Example: www.kayferg-store1.com = masks to beta.kayferg.com/magento/index.php/?___store=[STORE1] www.kayferg-store2.com = masks to beta.kayferg.com/magento/index.php/?___store=[STORE2]

  • What are unusual and creative usages of html5 canvas

    - by stej
    Canvas from html5 was introduced some time ago. Currently it's used (almost) only for demonstrations how cool it is - it's mainly related to painting, games and charts. Many of them can be found at Canvas demos. How creatively / unusually can canvas be used? Some examples: jsAscii - ASCII art from images with Javascript and Canvas (yea, I know, it's painting but not the classic one) Javascript compression using PNG and Canvas

  • Learning C bit manipulation

    - by VaioIsBorn
    I didn't know any better name for a title of the question. For ex: on one of my previous questions one answered ((a)-(b))&0x80000000) 31 - this is kind of a too advanced for me and i can't really get what it means. I am not looking just for an answer of that, but i need someone to tell me some books/sites/whatever where i can learn this cool "advanced" tricks in C - and learn how and where to use them respectively too.

  • C# Nested Property Accessing overloading OR Sequential Operator Overloading

    - by Tim
    Hey, I've been searching around for a solution to a tricky problem we're having with our code base. To start, our code resembles the following: class User { int id; int accountId; Account account { get { return Account.Get(accountId); } } } class Account { int accountId; OnlinePresence Presence { get { return OnlinePresence.Get(accountId); } } public static Account Get(int accountId) { // hits a database and gets back our object. } } class OnlinePresence { int accountId; bool isOnline; public static OnlinePresence Get(int accountId) { // hits a database and gets back our object. } } What we're often doing in our code is trying to access the account Presence of a user by doing var presence = user.Account.Presence; The problem with this is that this is actually making two requests to the database. One to get the Account object, and then one to get the Presence object. We could easily knock this down to one request if we did the following : var presence = UserPresence.Get(user.id); This works, but sort of requires developers to have an understanding of the UserPresence class/methods that would be nice to eliminate. I've thought of a couple of cool ways to be able to handle this problem, and was wondering if anyone knows if these are possible, if there are other ways of handling this, or if we just need to think more as we're coding and do the UserPresence.Get instead of using properties. Overload nested accessors. It would be cool if inside the User class I could write some sort of "extension" that would say "any time a User object's Account property's Presence object is being accessed, do this instead". Overload the . operator with knowledge of what comes after. If I could somehow overload the . operator only in situations where the object on the right is also being "dotted" it would be great. Both of these seem like things that could be handled at compile time, but perhaps I'm missing something (would reflection make this difficult?). Am I looking at things completely incorrectly? Is there a way of enforcing this that removes the burden from the user of the business logic? Thanks! Tim

  • Is there any way to test server side code using JSTestDriver?

    - by dhackner
    I'm new to JS unit testing and I like what I've read about JSTestDriver. The idea of have the suite run every time you save is pretty cool. JSTestDriver runs Javascript in a browser sandbox and PHP runs on the server. If the browser slaves can serve from an arbitrary server is there any reason that you couldn't test it via AJAX? It this a misuse/misunderstanding of what the framework is for? Any clarifications are appreciated.

  • How to repackage NVIDIA .run drivers into .deb with DKMS

    - by Delan Azabani
    At present, Ubuntu offers the 195.36.24 drivers as nvidia-current in their repository. This packaged driver is pretty cool as it uses DKMS so you don't have to keep reinstalling the driver after a new kernel version. The NVIDIA .run package drivers are at version 257 (beta) but they don't use DKMS so the graphics screws up every time a new kernel is installed and you don't reinstall the driver. How can I modify the .run to use DKMS and even better, package it as a deb package?

  • WPF Animation / Processing priority

    - by Matt B
    Hi all, I have a button which has an animation (in xaml) on it's click event. Cool so far. Problem is that I also have processing occurring on the click event (so I can do stuff) - and this occurs first. How do I prioritise or re-order so that the animation takes place before any custom processing... Thanks.

  • Using com.sun.net.httpserver.HttpServer for comet/cometd

    - by Paul
    Hi Wayne :) I want to use HttpServer, which you mentioned, and I think is cool to do comet/cometd. I am wondering how tough it is to do it so that I can take the waiting connections off the thread and into some waiting queue. Also, am I correct in that it looks like it is using nio? Also, is there any better examples? I always get caught up in the terminology that the javadoc uses... Thanks :)
