  • 'Quickly': How can I use Ruby?

    - by ragu.pattabi
    Recently I came across Quickly. A very nice thing Ubuntu is doing in order to simplify creation of good looking applications that integrates well with Ubuntu desktop in every respect. While the demo was so cool and even motived me to learn Python, I am only familiar with Ruby. I would really love if there is a way to make Quickly do similar thing with Ruby. I read something about templates; but couldn't locate much details.

  • Cairo-dock only shows one workspace after upgrade to 14.04 LTS

    - by David M. Karr
    I have a Linux desktop that I try to keep up to date, although I don't use it a lot. I had it configured with cairo-dock, showing 2x2 workspaces. It's been like this for quite a while. I recently upgraded to 14.04 LTS, and now the switcher only shows a single workspace. I read several posts that talk about similar problems, but I wasn't able to get a viable clue. What can I look at to get some clues?

  • how to track Google Analytics of Adobe Air app?

    - by dreagan
    I have written an Adobe Air desktop application that tracks a bunch of websites and displays images from the websites in the app. And instead of keeping my mouth shut about it and making it look like an attack on the website, I'd like to make it so that the webmasters can see that these pageviews are made by my application. Is there any way the webmaster could distinguish adobe air access of the website from normal visitor browsing? Perhaps by adding something to the URLrequests I make in the application..?

  • Friday Fun: Snowball

    - by Asian Angel
    It is Christmas Eve and hopefully you are enjoying the start of an early weekend away from work. This week we have a snowball throwing game for you to try out, so bundle up and get ready to let those snowballs fly! Snowball The object of the game is to use your snowball ammo to harass the drunk businessman and send him flying along distance-wise as far as you can. Simply use your mouse to aim and click the left button to throw snowballs. You can monitor your stats on the silver bar towards the top of the window. The sound can also be disabled if the music is bothering you, but keep in mind that all sound will be disabled if you use the option. Time to get those snowballs flying through the air!! Keep hitting the businessman with your snowballs as you chase after him. Make certain that your aim is good or you will quickly run out of snowballs! You can really get him moving along at a good rate and he can even go high enough in the air to disappear off the screen for a few moments. There is a also chance that your aim will be so wicked with the snowballs that you will literally knock the drunk businessman’s head off! Weird but possible… The game ends when one of these two events occur: 1.) you run out of snowballs or 2.) the businessman literally bounces back at and then drops behind you as seen in the screenshot here. The moment either happens your score will pop up and then you have the opportunity to try again. Have fun! Note: The bounce back event can happen when encountering cars.

  • Why does Unity screen blank out over XDMCP?

    - by James
    My XDMCP sessions display fine until I login. I've checked all logs and settings for this and can't find anything wrong, this works fine on other systems so I'm wondering if this has anything to do with the underlying hardware or an application that loads when logging in. System details: - Ubuntu 12.04 (Desktop, installed via Alternate CD for RAID) - 8GB of RAM - Core2Quad CPU @ 2.40GHz - Gigabit Network (Ethernet) Other notes: - Running with the onscreen keyboard enabled - Works fine when logging in locally Pre-login: Once logged in:

  • English-Focused Translation Bookmarklet for Your Browser

    - by Asian Angel
    Are you wanting a translation bookmarklet that just focuses on translating websites into English? Then you will want to take a look at the To English Bookmarklet. Get the Bookmarklet To install the To English Bookmarklet visit the webpage at Lifehacker (link below), grab the bookmarklet with your mouse, and drag it to your “Bookmarks Toolbar”. Now you are ready for one-click translation into English. To English in Action We decided to test our new bookmarklet on two different International Mozilla websites. The first one was in Swedish… One click and there it is. Notice that there is a “translation bar frame” that will still let you choose yet another language to translate the webpage into if you desire. Definitely a nice touch… Our second example was in Russian. Once again a single click and… The website is now in English. On this particular page the “central green graphic” was affected by the translation and the two sidebar buttons are “pre-made” but that is ok. You can read what you need to without any problems. Conclusion If you have been wanting a bookmarklet that just focuses on translating into English then this should be perfect for you. If you are looking for a bookmarklet that gives you access to a Google Translation Bar then be certain to see our article here.

  • OOW 2012: Kings of Leon & Pearl Jam - Appreciation Event

    - by Mike Dietrich
    June 15, 1992 - that was actually the day when Pearl Jam played their first concert in Serenadenhof in my hometown, Nürnberg. Oups ... that's over 20 years ago ... So I was so happy to get a ticket to this year's OOW 2012 appreciation event on Treasure Island. Every year it amazes me over and over again how the organizers manage it logistically to bring almost 40,000 people to and back from the island. Food was ... I would say fairly ok ... and beer (as always) is not - actually even though I'm not a beer drinker I wouldn't call it beer.  Kings of Leon did start. I like them a lot and owe their 2008 album Only By Night. That was a good start to warm up the crowd. And then Pearl Jam took over - and ... wooooooow ... they are such a great live band. First of all as far as I understood they were donating the money they've got for that gig to an NGO. And Eddie Vedder's voice is simply striking ... I had shivers running down my spine. They played a good excerpt of their +20 years career closing down with Alive at the very end. It seemed to everybody that the band had real fun playing there - and it was sooooo good. Thanks a lot to the person who did organize me a ticket Catching my bus back to my hotel area down at Fisherman's Wharf worked well - but I must have fallen asleep 5 minutes after we've left the parking lot. The next thing I did recognize was the bus driver pushing the breaks at Northpoint. What a wonderful night ...

  • How To Disable Individual Plug-ins in Google Chrome

    - by The Geek
    Have you ever wondered how to disable useless or insecure browser plug-ins in Google Chrome? Here’s the lowdown on how to get rid of Java, Acrobat, Silverlight, and the rest of the plugins you probably want to get rid of. Disabling Plugins in Google Chrome If you head to about:plugins in your address bar, you’ll probably see a list of plugins, but won’t be able to disable them yet. What you’ll need to do is switch over to the Dev channel of Chrome, which gives you access to all the latest features—though you might be warned that sometimes the dev channel might be less stable than the release or beta channels. Ready to proceed? Head to the Dev Channel page, and then click the link to run the installer. You’ll be prompted to restart Chrome when you’re done. Note that Mac and Windows users can both run an installer to switch. Linux users will have to install a package. Note: Once you’ve switched to the Dev channel, you can’t really switch to the stable channel. You’ll have to uninstall Chrome and then reinstall the regular version. Now that you’ve switched to the dev channel and restarted your browser, head to about:plugins in the address bar, and then just disable each plugin you really don’t need. Plugins you can generally live without?  Java, Acrobat, Microsoft Office, Windows Presentation Foundation, Silverlight. These will be on a case-by-case basis, of course, but the vast majority of large websites don’t require any of those. When it comes right down to it, the only plugin that most people require is Flash… and leave the “Default Plug-in” alone too. Special thanks to @jordanconway for pointing out the solution.

  • Example of DOD design (on a generic Zombie game)

    - by Jeffrey
    I can't seem to find a nice explanation of the Data Oriented Design for a generic zombie game (it's just an example, pretty common example). Could you make an example of the Data Oriented Design on creating a generic zombie class? Is the following good? Zombie list class: class ZombieList { GLuint vbo; // generic zombie vertex model std::vector<color>; // object default color std::vector<texture>; // objects textures std::vector<vector3D>; // objects positions public: unsigned int create(); // return object id void move(unsigned int objId, vector3D offset); void rotate(unsigned int objId, float angle); void setColor(unsigned int objId, color c); void setPosition(unsigned int objId, color c); void setTexture(unsigned int, unsigned int); ... void update(Player*); // move towards player, attack if near } Example: Player p; Zombielist zl; unsigned int first = zl.create(); zl.setPosition(first, vector3D(50, 50)); zl.setTexture(first, texture("zombie1.png")); ... while (running) { // main loop ... zl.update(&p); zl.draw(); // draw every zombie } Or would creating a generic World container that contains every action from bite(zombieId, playerId) to moveTo(playerId, vector) to createPlayer() to shoot(playerId, vector) to face(radians)/face(vector); and contains: std::vector<zombie> std::vector<player> ... std::vector<mapchunk> ... std::vector<vbobufferid> player_run_animation; ... be a good example? Whats the proper way to organize a game with DOD?

  • Corporate Wiki Organization - Technical Documentation

    Corporations have documents describing various aspects of their technical systems, including: Custom Applications Custom Development Frameworks Third Party Applications Accounting Bug Tracking Network Management How To Guides User Manuals Software Tools Web Browsers Development IDEs Graphics GIMP xv Text Editing File Transfer ncFTP WinSCP Hardware Servers Web Database Exchange File Network Devices Printers If you had to use a Wiki to manage the documentation, what other items would you add to the list, and how would you organize it? (For example, would Software Tools make more sense under Third Party Applications?) A few constraints: The structure should not go beyond three levels deep. Avoid the word "and" in favour of two different categories. Keep the structure general: it should appy as broadly as possible. Target audience is primarily technical, but could be visible by anyone.
