  • How do I change the volume control icon?

    - by Richard Oren Pincook
    I recently switched to gnome 3 (love it!), but the default icon theme was a little dreary and gray, so I switched that back to ubuntu-mono-dark. But now whenever I change my volume, I get this ugly pixelated icon show up. The forum says I don't have enough reputation to post an screenshot, but it's pixelated and ugly with these fuzzy straight blue lines that turn on as the volume goes up. I found identical images in the Humanity and Humanity-Dark icon themes (one example: /usr/share/icons/Humanity/status/24/audio-volume-high.png). I tinkered with the images by changing their names, temporarily deleting them, etc. But it had no effect on the ugly icon. What file is responsible for violating the beauty of my desktop?! Once I find it, I can replace it.

  • 24 Hours of PASS – first reflections

    - by Rob Farley
    A few days after the end of 24HOP, I find myself reflecting on it. I’m still waiting on most of the information. I want to be able to discover things like where the countries represented on each of the sessions, and things like that. So far, I have the feedback scores and the numbers of attendees. The data was provided in a PDF, so while I wait for it to appear in a more flexible format, I’ve pushed the 24 attendee numbers into Excel. This chart shows the numbers by time. Remember that we started at midnight GMT, which was 10:30am in my part of the world and 8pm in New York. It’s probably no surprise that numbers drooped a bit at the start, stayed comparatively low, and then grew as the larger populations of the English-speaking world woke up. I remember last time 24HOP ran for 24 hours straight, there were quite a few sessions with less than 100 attendees. None this time though. We got close, but even when it was 4am in New York, 8am in London and 7pm in Sydney (which would have to be the worst slot for attracting people), we still had over 100 people tuning in. As expected numbers grew as the UK woke up, and even more so as the US did, with numbers peaking at 755 for the “3pm in New York” session on SQL Server Data Tools. Kendra Little almost reached those numbers too, and certainly contributed the biggest ‘spike’ on the chart with her session five hours earlier. Of all the sessions, Kendra had the highest proportion of ‘Excellent’s for the “Overall Evaluation of the session” question, and those of you who saw her probably won’t be surprised by that. Kendra had one of the best ranked sessions from the 24HOP event this time last year (narrowly missing out on being top 3), and she has produced a lot of good video content since then. The reports indicate that there were nearly 8.5 thousand attendees across the 24 sessions, averaging over 350 at each one. I’m looking forward to seeing how many different people that was, although I do know that Wil Sisney managed to attend every single one (if you did too, please let me know). Wil even moderated one of the sessions, which made his feat even greater. Thanks Wil. I also want to send massive thanks to Dave Dustin. Dave probably would have attended all of the sessions, if it weren’t for a power outage that forced him to take a break. He was also a moderator, and it was during this session that he earned special praise. Part way into the session he was moderating, the speaker lost connectivity and couldn’t get back for about fifteen minutes. That’s an incredibly long time when you’re in a live presentation. There were over 200 people tuned in at the time, and I’m sure Dave was as stressed as I was to have a speaker disappear. I started chasing down a phone number for the speaker, while Dave spoke to the audience. And he did brilliantly. He started answering questions, and kept doing that until the speaker came back. Bear in mind that Dave hadn’t expected to give a presentation on that topic (or any other), and was simply drawing on his SQL expertise to get him through. Also consider that this was between midnight at 1am in Dave’s part of the world (Auckland, NZ). I would’ve been expecting just to welcome people, monitor questions, probably read some out, and in general, help make things run smoothly. He went far beyond the call of duty, and if I had a medal to give him, he’d definitely be getting one. On the whole, I think this 24HOP was a success. We tried a different platform, and I think for the most part it was a popular move. We didn’t ask the question “Was this better than LiveMeeting?”, but we did get a number of people telling us that they thought the platform was very good. Some people have told me I get a chance to put my feet up now that this is over. As I’m also co-ordinating a tour of SQLSaturday events across the Australia/New Zealand region, I don’t quite get to take that much of a break (plus, there’s the little thing of squeezing in seven SQL 2012 exams over the next 2.5 weeks). But I am pleased to be reflecting on this event rather than anticipating it. There were a number of factors that could have gone badly, but on the whole I’m pleased about how it went. A massive thanks to everyone involved. If you’re reading this and thinking you wish you could’ve tuned in more, don’t worry – they were all recorded and you’ll be able to watch them on demand very soon. But as well as that, PASS has a stream of content produced by the Virtual Chapters, so you can keep learning from the comfort of your desk all year round. More info on them at sqlpass.org, of course.

  • Wifi won't work without ethernet (Ubuntu 12.04)

    - by alok
    I have a strange problem. I am running Ubuntu 12.04 on a Dell Studio 1558 laptop. I'm usually unable to access Wifi (I have a BCM43224 wireless card with the STA proprietary driver installed.) So I have to unplug the ethernet cable from my Wifi router and stick it into my laptop's ethernet port to access the Internet. But when I stick the cable back into the Wifi router and try connecting to Wifi, Wifi inexplicably starts working. How can I get Wifi to work all the time without having to 'jumpstart' it with an ethernet connection?

  • How do I install the Intel Graphics driver in my system?

    - by John
    Can someone help me out and explain or point me in the right direction on how to check video drivers and see if my video card running okay? I had 10.04 installed on my Thinkpad r61 with Compiz Manager and life was great, until the machine took water damage. I bought an ASUS (X54H) since and am trying out 12.04, but the desktop just doesn't look right. I always struggled with video driver installation. There are no proprietary drivers available in the hardware manager. When I run lspci | grep VGA: 00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09) I will greatly appreciate your help. I want to use Linux more, but like I said video drivers appear to be my biggest concern. I have also tried 12.04 on my desktop PC, but again failed to configure video card, so switched back to Windows 7.

  • What's the best platform for blogging about coding ?

    - by timday
    I'm toying with starting an occasional blog for posting odd bits of coding related stuff (mainly C++, probably). Are there any platforms which can be recommended as providing exceptionally good support (e.g syntax highlighting) for posting snippets of code ? (Or any to avoid because posting mono-spaced font blocks of text is a pain). Outcome: I accepted Josh K's answer because what I actually ended up doing was realizing I was more interested in articles than a blog style, getting back into LaTeX (after almost 20 years away from it), using the "listings" package for code, and pushing the HTML/PDF results to my ISP's static-hosting pages. (HTML generated using tex4ht). Kudos to the answers mentioning Wordpress, Tumblr and Jekyll; I spent some time looking into all of them.

  • 2D wave-like sprite movement XNA

    - by TheBroodian
    I'm trying to create a particle that will 'circle' my character. When the particle is created, it's given a random position in relation to my character, and a box to provide boundaries for how far left or right this particle should circle. When I use the phrase 'circle', I'm referring to a simulated circling, i.e., when moving to the right, the particle will appear in front of my character, when passing back to the left, the particle will appear behind my character. That may have been too much context, so let me cut to the chase: In essence, the path I would like my particle to follow would be akin to a sine wave, with the left and right sides of the provided rectangle being the apexes of the wave. The trouble I'm having is that the position of the particle will be random, so it will never be produced at the same place within the wave twice, but I have no idea how to create this sort of behavior procedurally.

  • Alt Key + Mouse Scroll is the New Text Zoom In/Out in NetBeans

    - by Geertjan
    When the text zoom in/out, via "Ctrl Key + Mouse Wheel", was introduced in editors in a recent version of NetBeans IDE, many people cheered. Others booed because the combination "Ctrl Key + Mouse Wheel" is often pressed accidentally, especially when the user scrolls in the editor while intending to use some Ctrl shortcut, such as paste, which is Ctrl-v. So, in NetBeans IDE 7.2, the text zoom in/out is now "Alt Key + Mouse Wheel": http://netbeans.org/bugzilla/show_bug.cgi?id=212484 Remember that the text change only persists for as long as the file is open. So, if you've accidentally resized the text (i.e., in the current situation, prior to 7.2, where unintended side effects may happen because of Ctrl key usage), you can just close the file and reopen it to get the text size back to the way it was before.

  • Which version of Ubuntu is recommended for app developers?

    - by Wes
    I've searched around Ask Ubuntu and the App Developer site, but I can't seem to find the answers to my questions. I'm wanting to get back into programming, and I'd eventually like get into app development for Ubuntu, but I'm not sure where to get started. Which version of Ubuntu is currently recommended for app development, especially for those wanting to publish their apps to the Software Centre? Should app developers use the current LTS release, or, can any of the new releases be used? Should developers use the 32-bit or 64-bit edition of Ubuntu, or does this not matter? What effect would the above choices have on the eventual publication of an app? I'm truly sorry if this has been covered elsewhere. Cheers Wes

  • How does a BSP tree work for Z sorting?

    - by Jenko
    I'm developing a 3D engine in software, and so I must compute Z sorting manually. I'm currently using the painters algorithm to sort triangles and then drawing them back-to-front. This causes artifacts that I'm trying to correct. Would using a dynamic BSP-tree ensure "correct Z sorting" of triangles? Why? Because the bounding volumes of triangles would be similar? Since I would have a single "world" BSP tree, would I have to remove and re-add any moved/scaled/rotated object into the tree? Is it possible to add triangles into a BSP tree without the expensive cutting process? Why do you need to cut triangles on the axis planes anyway? Is it faster to traverse a BSP tree from any angle, than to sort all tris each draw like the painters algorithm?

  • Getting Started on Isometric Board Game port

    - by Jehosephat
    I have developed a (off-line) board game that I would like to translate to an online/social game in an isometric grid perspective. My background is in .NET web development, so I'm very comfortable with C#, HTML, jQuery/javascript. Still getting my feet wet with HTML5. I have familiarity with Flash, but I haven't worked with it in years. I'm also interested in working with Azure for hosting the back-end. Ultimately I'd like this game to have persistent leaderboard/achievements and therefore be able to log in through FB and Kong and the like. Obviously, I'm not looking for 'here's exactly how to do all of this'. But I would love some opinions on where to start, particularly given my background and goals. Would be happy to share more details if it makes answering easier! Thanks!

  • Can I hook my xbox up to my Ubuntu PC

    - by Anonymous John
    My old xbox 360 won't eject disks, it makes a sound,but won't open. I want to play games, so I think I could hook it up to my PC running Ubuntu 13.10 64-bit and maybe I could use my PC's DVD drive. Can this work at all, or am I just crazy? There is an HDMI port on the back of my graphics card. If I can't do that, is there any software for Ubuntu that can rip the game off of a CD and put it on a flash drive? I have heard xbmcbuntu works great for gaming, but it doesn't work with my PC.

  • Objected oriented approach to structure inside structure

    - by RishiD
    This is for C++ but should apply to any OO language. Trying to figure out the correct object oriented apporach to do the following (this is what I do in C). struct Container { enum type; union { TypeA a; TypeB b; }; } The type field determines if it TypeA or TypeB object. I am using this to handle responses coming back from a connection, they get parsed and get put into this structure and then based on the message type the appropriate fields get filled in. e.g. struct Container parseResponse(bufferIn, bufferLength); Is there an OO approach for doing this?

  • Where are the LXDE sound preferences?

    - by Uri Herrera
    I'm confused,how can I change the sound output in LXDE? There's not even a single option anywhere unlike other environments. I've tried doing anything with alsamixerbut still nothing, the output device is the HDMI audio of a Radeon HD card. Edit: As it Turns out i was able to change the ouput device, but i had to use Gnome for that and its Gnome Sound applet, that is log out and log in in Gnome change the device, log out and log back in LXDE. Now the question becomes Why can't i do this in LXDE?

  • URL structure for content that is updated daily

    - by Brendon
    A small, simple site I am working on displays a single page with the day's best offers on it. The user is able to move back and forth between previous days. Which of the following URL structures works best? Structure 1 /index.html -- today's best offers /2013-06-29.html -- yesterday's best offers, etc. Structure 2 /index.html -- 302 redirects to /2013-06-30.html (or whatever today is) /2013-06-30.html -- today's best offers /2013-06-29.html -- yesterday's best offers, etc. I quite like structure 2 from the user's point of view (they can share content easily), but I am a bit concerned about updating the redirect from /index.html every single day -- would this perhaps have unintended SEO consequences?

  • Republishing blog posts on a popular website

    - by Giorgi
    I started my blog about programming yesterday and in order to promote and increase traffic I submitted my rss to Codeproject which pulls my posts and publishes them at Codeproject. While it increases the number of people reading my posts (but they are reading it at codeproject) I am worried that Google will penalize my site for duplicate content (Especially considering that Codeproject has much more reputation compared to my new website). The post at Codeproject has a link back to my blog post but it does not have "rel=canonical". So my question which one is better: a link from a high reputation website and some traffic or should I remove it from codeproject so that my blog is not penalized? What if codeproject adds "rel=canonical" to the link?

  • Ubuntu slow on HP 2000 notebook with Apu e1-1200

    - by user169861
    I am using HP 2000 notebook which initially came with Windows 7 64bit. It has 4gb ram, AMD APU E1-1200 (1.4ghz) with Radeon 7310. With Windows it worked ok, so I decided to switch to Ubuntu. I installed 13.04 64bit at first, but responsiveness wasn't that good (opening windows, menus, Firefox, dash search) even if it was way better during the testing from live USB. I tried different kind of drivers for graphic card, 13.6beta, 13.4, fgrlx proprietary, upgraded kernel but the situation was the same. Then I tried installing 32bit version but the results were identical. After that I tried LTS version 12.04 and Xubuntu 13.04.. Responsiveness wasn't that different at all. Not sure what to do, and I wouldn't want to go back to Windows. This machine is not a beast, but it should be enough to deal with Unity or Xfce without troubles. Oh yes, I have insydeH20 BIOS with not so many options at my disposal. Thanks and best regards,
