    - by Falk
    in advance: my English is not perfect ;) processor: Intel® Core™2 Duo CPU E8500 @ 3.16GHz × 2 memory: 3,9 GiB graphics: GeForce GTX 460 Ubuntu 12.04 32-Bit fresh installed (previously 11.10 32-Bit) driver: NVIDIAs accelerated Driver (Version current-updates) probelm: In Ubuntu 12.04 I have problems with the performance of the graphics (games for example: Volley Brwawl, Neverball, Beep and Minecraft), and effects of windows (always at minimize, maximize...) There are laggs at animations, and the laggs in games are extremely annoying. Problems occur only in Ubuntu 12.04, everything was good in 11.10. No Problems with YouTube videos, HD videos. Is there a solution? BBecause I have found nothing here in the Forum and on Google. Or is an update coming soonfor driver or whatever? (This Bug is already registered in Launchpad.) Thank you!

  • Does SEO optimisation count on the responsive side of a site?

    - by Rick Donohoe
    I'm looking at making some SEO optimisation fixes, and at this point I'm sorting out the heading structure and keywords - H1's, H2's etc We have a site where there are a number of similar blocks, and one is always visible, and one is hidden depending on the screen size. This is our method of making a single site responsive. Firstly, how does this technique affect the SEO, and in general does the responsive side of a site matter at all to search engines? What I mean by this is if the site has different content depending on screen sizes, then which content would the search spider crawl?

  • [Dear Recruiter] I'm an engineer trapped in a kittens body.

    - by refuctored
    Aditya -- I am very interested in pursuing the opportunity you've presented to me.  Let me assure you, there are very few individuals in Indianapolis with the skill set which I have so passionately trained to acquire.   Accompanying my skill set I do have a few quirks that you'll need to be okay with prior to placing me at a company. Bluntly, I feel like I'm a software engineer trapped in a cute little kitten's body.  I find that I am most comfortable going to work with a few stripes and whiskers painted on my face.  Coworkers will need to be okay with me grooming myself and making kitten noises whilst I do so.  I do occasionally let out a purr now and then, but not loud enough to disrupt anyone.  I always throw my arm-hair-balls in the appropriate trash receptacle. Will your company provide a scratching post or will I need to bring my own?  I can bring my own litter box. Meow-muh,George

  • Newly installed 12.04 on Radeon or NVIDIA type of gfx card?

    - by Falk
    I use a Nvidia Quadro NVS 290/PCIe/SSE2 at work with dual monitor setup. Since 11.10 things has gone downwards with performance. But now with 12.04 performance is even worse, and I can agree that the 290 is old and puny. So when I look what low profile cards I can get to my computer today, the choice it Radeon HD 6570 or NVIDIA Quadro 600. I have always used Nvidia on linux beq I think that historically their drivers worked better. But which one do you recommend today on 12.04 and Unity3d? -- Regards Falk

  • Sceptic in a SCRUM Team

    - by Sorantis
    My company has recently switched to an Agile WoW and as a part of it we've started using SCRUM. While I'm very comfortable with it and feel that this WoW is superior to a traditional one, some of my teammates don't share the same opinion. In fact they are very skeptical about "all that agile stuff", and don't take it seriously. As an example, one of the teammates is always late on the meetings, and doesn't really care about it. The management IMO tries not to notice this (maybe because it's a new Wow, and it takes time for the people to get used to it). My question is, how to address this issue not raising a conflict inside the team?

  • How to reload Variety wallpaper changer?

    - by mayur
    I have installed Variety desktop wallpaper changer. Its a good app. But sometimes when I start Ubuntu and login to my account it fails to load. I try to manually start the app by clicking on variety icon, but doesnt work. I tried alt+F2 and enter 'killall gnome-panel' but nothing seems to happen. I checked in my startup applications window, variety is present there to start when Ubuntu starts. but then why it does not start always? Restarting my pc is the only solution then. Is there a way that I can reload Variety without logging off or restarting Ubuntu? Thanks in advance.

  • ASP.NET Tooltips Extender Control

    Tooltips is always a good usability practice to display descripitve and meaningful message on UI, which provide guidance and extra information to users visually. However, I cannot find this kind of handy "control" in the latest version (40412) of the AJAX control toolkit. (Feature request?) The traditional HTML "title" or "tooltips" tag of control cannot make the users (nor even developers) happy, so I searched and found this Tooltip Extender control today.

  • Checking whether the user input is a str in Python [migrated]

    - by Sahil Babbar
    I checked various questions on Stack Overflow but one thing every logic lacks. Let me demonstrate using Python: while True: user_input = raw_input() if type(user_input) == str: print 'ERROR' else: print 'BINGO' Also, we cannot use input() in place of raw_input() as it gives the error:Traceback (most recent call last): File ".\test.py", line 3, in <module> user_input = int(input()) File "<string>", line 1, in <module> NameError: name 'asdf' is not defined The problem here is that raw_input converts the user input into string so it always prints 'ERROR' and if I change the second line to user_input = int(raw_input) then, it gives an error: Traceback (most recent call last): File ".\test.py", line 3, in <module> user_input = int(raw_input()) ValueError: invalid literal for int() with base 10: 'asdf' I tried this with try and except but it shall work fine to check integer but not a string. I feel that this question may be marked as a duplicate but I think that this query is important, if logically taken.

  • How do I make Unity quit opening Firefox under the Shiretoko icon?

    - by Azendale
    I'm using Ubuntu 12.04, and whenever I open Firefox, whether it is from searching on the dash or clicking a 'quick-launch' launcher, it always opens yet another icon for the running instance that is a blank page and says Shiretoko. It will pulse the Firefox icon for a while (I'm guessing until a timeout or something). It's as if Unity no longer recognizes the Firefox process as Firefox and misidentifies it as Shiretoko. (I know Shiretoko was a testing version of Firefox a long time ago.) How do I set Unity straight? I imagine that it has something to do with me once using Shiretoko, but I believe that was even on a different installation, just the same home folder. Is there some place Unity caches this information that I can clear (or remove specific parts of)?

  • Follow the deadlines vs Do it right

    - by QuiteNothing
    I have been given a huge task of migrating few functionalities from jQuery to AngularJS. I have been pretty good at Angular by now. But I want to dive deep and create futuristic, sound architecture. BAs are seating on my neck, wanting to get my tasks as quickly as possible. I prefer doing something once and right vs keeping on patching existing functionalities. And with this attitude, I always keep working more than necessary. Am I missing something? Am I having right approach or am just not convincing enough BAs my point. What's the best approach, in your opinion Thank You :)

  • Why is this happening with the wine menu?

    - by Patrick
    Some of the items in the Wine menu are given a prefix that is their entire path. The items that don't have the long prefix seem to work fine, but those that do, don't respond to the Properties button or double-click in the menu editor. They take a lot of space, and look ugly, but I can't rename them. I've tried editing their associated files, there doesn't appear to be anything different about them to the ones that are working fine. They weren't always like that - it just happened after an upgrade one day and it's been like that ever since.

  • What percent of visitors should click on the next page before you enable prefetching?

    - by Kevin Burke
    Mozilla Firefox and Google Chrome support prefetching via an HTML tag: <!-- in chrome --> <link rel="prerender" href="http://example.org/index.html"> I suppose it is always worthwhile to include this tag if 100% of users on a page click on the "Next Page" button or similar, and never worthwhile to include it if only 2% or 3% of users visit the following page. At what percent of clicks should you turn on prefetching of the next page? 65%? Also, does the calculus change if the current page is HTTP and the next page is HTTPS?

  • Project life cycle management - Maven vs 'manual' approach

    - by jb10210
    I have a question concerning the life cycle management of a/multiple project(s), more specific to the advantages/disadvantages of using technologies such as Maven. Currently we work in a continuous-integration environment but lots of things still need to be manually performed (dependency management, deploying, setting up documentation, generating stats, ...). My impression is that this approach often leads to errors, miscommunications or things just are forgotten. I know and have used Maven in the past but in smaller environments and I was always really enthusiastic about it. But I was wondering if someone could share some insights, experiences, pros, contras, ... about the use of Maven (or similar technology) in larger environments and for multiple projects. I would like to use the suggestions made here to start the debate about moving to the next level in project management!

  • Disabled WiFi but it keeps re-enabling itself; want it to stay disabled

    - by Mike Uresti
    I have an Alienware X51 desktop with a wireless card, I have it connected via ethernet and want to permanently disable WiFi from ever using itself. When running Windows, I go to device manager and rightclick-disable the Wireless card and that takes care of my problem. Is there a similar method using Ubuntu 14.04? For now, I click on the network icon in the system tray and uncheck 'Enable wifi' but it seems to turn itself back on as I use my computer, I think I have the incident isolated to something with Steam. It seems like after I start the Steam client it always is re-enabled. Hopeful answer: Just disable/remove/block wireless card from ever working.

  • Objects disappear when zoomed out in Unity

    - by Starkers
    Ignore the palm trees here. I have some oak-like trees when I'm zoomed in: They disappear when I zoom out: Is this normal? Is this something to do with draw distance? How can I change this so my trees don't disappear? The reason I ask is because my installation had a weird terrain glitch. If this isn't normal I'm going to reinstall right away because I'm always thinking 'is that a feature? Or a glitch'?

  • Why to let / not let developers test their own work

    - by pyvi
    I want to gather some arguments as to why letting a developer testing his/her own work as the last step before the product goes into production is a bad idea, because unfortunately, my place of work sometimes does this (the last time this came up, the argument boiled down to most people being too busy with other things and not having the time to get another person familiar with that part of the program - it's very specialised software). There are test plans in this case (though not always), but I am very much in favor of making a person who didn't make the changes that are tested actually doing the final testing. So I am asking if you could provide me with a good and solid list of arguments I can bring up the next time this is discussed. Or to provide counter-arguments, in case you think this is perfectly fine especially when there are formal test cases to test.

  • Create Adventure Game Scene/Room/Backdrop from Real Photo

    - by Lyuben
    Is there a suitable software or a good tutorial for creating 2D rooms/scenery for adventure games from real photos? Is it possible to achieve good results by using photos, or the hand-drawn style will always be the best choice? Thank you! --- EDIT --- I want to clarify that I'm particularly interested in the art creation process, not on the environment in which to build games. I'm writing the game in Java for Android, but I don't think it matters. Also, I'm not trying to decide if the game will have photo realistic rooms or not - I want to achieve 2d pixelated, old-school style background scenes and I wonder if this can be made from photos, because I cannot draw them myself. For example, can I shoot a scene with my camera and then make it look something like the image in the following link: PIXEL ART FOREST I know that I cannot get the same quality as an absolutely hand-drawn pixel, but I'm looking for some decent technology/tutorial/software to make them somewhat similar.

  • Confusion about Rotation matrices from Euler Angles

    - by xEnOn
    I am trying to learn more about Euler Angles so as to help myself in understanding how I can control my camera better in the game. I came across the following formula that converts Euler Angles to rotation matrices: In the equation, I could see that the first matrix from the left is the rotation matrix about x-axis, the second is about y-axis and the third is about z-axis. From my understanding about ordinary matrix transformations, the later transformation is always applied to the right hand side. And if I'm right about this, then the above equation should have a rotation order starting from rotating about z-axis, y-axis, then finally x-axis. But, from the symbols it seems that the rotation order start rotating about x-axis, then y-axis, then finally z-axis. What should the actual order of the rotation be? Also, I am confuse about if the input vector, in this case, would be a row vector on the left, or a column vector on the right?

  • How can i get almost pixel perfect collision detection in a multiplayer game?

    - by Freddy
    I'm currently working on a multiplayer game for iPhone. The problem i have, as with all multiplayer games, is that the other user will always see everything at a non-constant delay. The game I'm making need to have a almost pixel perfect collision detection, but 1 or 2 pixels off is not that big of a deal. How can I possibly get this working? I guess I could just set local player to also be at X ms delay. However this will probably just be worse and feel sloppy when the user input. I know this problem is probably something network programmers deal with everyday and I would be glad if someone could give me a possible solution for this.

  • From the Classroom to the Boardroom

    - by Maria Sandu
    Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4 Pens and Paper...these are the only things being a student and being a graduate / professional have in common. Walking in to the offices of Oracle South Africa as a graduate the first thing you notice is how polished and sleek all the people who work here look. 80% of the ladies wear sky-scraper heels and walk with the greatest grace. This was the first of many rude awakenings to remind me that I am no longer a student but a graduate. My first struggle was having to wake up at wee hours of the morning to prepare for work. As a student going to class was almost an optional thing, if you missed a morning class you could always attend an evening class to make up for it or simply attend with another group. But in the workplace, you HAVE to show up every single morning at the same time, with no option of coming in when it suits you and there is definitely no coming in with the evening class/shift. As a student, the earliest hour I ever woke up was 7:00am, anything earlier than that was considered inhumane torture. My reason for waking up every morning as a student was “you have a degree to go get” but as a graduate having to go to work I have to say to myself “here’s to a new day of learning and growing”. My second struggle has come in having to change my beloved wardrobe. Everyone who knows me knows how passionate I am about fashion and shopping. For me Shopping is a BASIC HUMAN RIGHT, that should not be messed with. Therefore it was with great sadness that I swopped my rippled skinny jeans for pin-striped formal pants, my long chandelier earrings for simple studs, my flat shoes for heels, my sheer blouses for crisp white shirts, even my beloved wild hair had to make way for a simple ponytail. Our looks as ladies also came under great scrutiny, we had to acquaint ourselves with some serious grooming tools: the mascara, blush, lip-gloss, blush, a touch of lipstick and a manicure set. Language was a struggle of its own as well. Being a student you learn to relate to your peers in a informal way. In the workplace you have to address everyone with the same respect, including your peers. Words like “Hey buddy” had to make way for “good morning friend”. The month long winter school holiday was one of the things I looked forward to as a student. This was a time where we got to be at home and avoid the coldest month of the year, July. It was the most amazing thing ever, just sleeping and snuggling up to all sorts of warm things but sadly it is now a thing of the past. It is currently winter in South Africa and going to work has become the most unfashionable thing with all the jackets, boots, scarves and gloves. But summer is coming and I will miss those holidays too. As a student the school holidays were like a gift for us to catch a break and not think for a while which was why it was imaginable how someone would go on for the entire year without a break, with only the promise of a mere 21 days annual leave!! Right now I am sure we are all looking forward to taking that annual leave when the time is right. The worst rude awakening I must say, has to be presenting in front of clients and managers. As a student you have the same class mates for almost four years therefore presenting in front of them becomes the norm over the years and your lecturer will always go gently on you. What they don’t tell you at University is that in the real world, time is money and clients pay money to see you present therefore there is no room for error. Clients are not there to give you a score and boost your ego, they expect nothing less than 100% and they will let you know without a second thought. For a graduate this can feel like you are being fed to the sharks, you either get eaten or you swim for your life. At the end of the day, it is all an experience that is meant to groom us into better professional and make us a part of the Red Team. All the sacrifices are worth it and they lead us to being better and more polished professionals.

  • What are the system requirements for each flavor of Ubuntu Desktop?

    - by Braiam
    I'm thinking about installing Ubuntu Desktop, but I don't know what flavor is the better for my system. What are the minimum and recommended hardware requirements? What kind of CPU? How much memory? Should I have Hardware Acceleration? What flavor should I use? This is an attempt of a canonical answer. My answers have the "official minimal requirements", the recommended are a mix of official sources and opinion based (along with the answer it's told the source). You can comment or edit if you feel that the information is obsolete or incomplete. Is a good rule of thumb that any system capable to run Windows Vista, 7, 8 x86 OS X will almost always be a lot faster with any Ubuntu flavor even if they are lower-spec than described below.

  • Macbook Pro late 2011 screen brightness issue

    - by buchzumlesen
    The keys to set the screen brightness work properly but everytime I reboot, the screen brightness is reverted to 100%, which is very annoying. I've already tried to add the following lines to /etc/rc.local but with no success (only the keyboard backlight stays off): #!/bin/sh -e # # rc.local # # This script is executed at the end of each multiuser runlevel. # Make sure that the script will "exit 0" on success or any other # value on error. # # In order to enable or disable this script just change the execution # bits. # # By default this script does nothing. echo '1' > /sys/devices/platform/applesmc.768/leds/smc::kbd_backlight/brightness echo '6' > /sys/class/backlight/acpi_video0/brightness rfkill block bluetooth exit 0` This worked for me when I was using Ubuntu 12.04 and also did after the upgrade to 12.10 but then after rebooting the screen brightness always reverted to 100%. Would be nice if anyone knows how to fix this. My device: Macbook Pro 13" Late 2011 Thanks in advance!

  • How do you properly word a Google search when you don't even have a solution in mind? [closed]

    - by Bruno Romaszkiewicz
    So, I'm stuck on a problem, looking for a solution, my rubber duck can't help me, my co-workers can't help me. Next natural step is research, right? Google can help me, He always can. Or so I'm told. My problem is, I never found much use for Google when looking for a programming solution, it's very useful for finding how to implement one, but when you don't even know where to start, how do you properly word a Google search? Is there any other option?

  • Are there some methodologies to define a game's rules?

    - by bAN
    I would like to write some rules for a game I have in head but I don't know how to do that. So are there some methodologies or modeling tools (like UML) to do that? I'm thinking about a kind of tree of competencies or some kind of map to be sure that the game is well balanced. I always wonder how the team who imagines some powers in magic the gathering for example does it. Do they have some diagrams to be sure the powers or creatures they imagine are well balanced for the entire game? I'm pretty noob in the game creation so I'll be happy with some directions to seek.. Technical terms or basic principles to learn. Thanks for help.
