• Ubuntu install and dual Boot with Windows 8 UEFI

  - by Jose Maria

  i have Ubuntu 12.04 x64 ISO, i load it on a Fat32 USB. My notebook has a hdd with GPT where i installed Official Win 8 Pro x64 (final versión), I partitioned the whole hdd, previously of win 8 install, and bios is set with UEFI boot. My BIOS notebook doesn't support SECURE UEFI BOOT. So I boot the notebook from USB and the Grub runs OK showing whether to run Ubuntu live or to install, but neither one neither two works, when I choose then the screen shows black and nothing happen, it doesn't start/loads the install program. I've try whether to prepare the usb with unetbootin, or just direct copy/paste the files onto the USB. I also have try WUBI, but neither with success, it launch an error when ending.

• Rotate 3D Model from a custom position

  - by Nipuna Silva

  I have a 3D Model like above in which i want to rotate it from a given location(pointed in red) but I can only rotate it from the middle. How can I rotate it from a custom point. Edit: I successfully able to rotate the model from the below position by getting the radius of the model and applying it to the world matrix Vector3 point = new Vector3(-radius, 0, 0); world = Matrix.CreateTranslation(-radius, 0, 0); But now I cannot change the position of the object and it always centered in middle of the screen. I think that's because i applied the above code. How can I place it anywhere I want?

• How to add a sound that an enemy AI can hear?

  - by Chris

  Given: a 2D top down game Tiles are stored just in a 2D array Every tile has a property - dampen (so bricks might be -50db, air might be -1) From this I want to add it so a sound is generated at point x1, y1 and it "ripples out". The image below kind of outlines it better. Obviously the end goal is that the AI enemy can "hear" the sound - but if a wall is blocking it, the sound doesn't travel as far. Red is the wall, which has a dampen of 50db. I think in the 3rd game tick I am confusing my maths. What would be the best way of implementing this?

• Is your company successfully applying Application Lifecycle Management?

  - by Eric Nelson

  Two separate emails arrived in my Inbox. Email #1: The results of  detailed survey of UK ISVs which we had commissioned – what makes them tick etc. In that survey it stated “76% of ISVs do not use any ALM tools”. It also stated that of those that did, most only did the basics. I#m not surprised … but I am disappointed. Email #2: The wonderful Black Marble have gone all Xmasy and are offering Visual Studio ALM health checks with chances to win an Xbox 360 + Kinect each week of Dec. It therefore seemed obvious to me that I should do my little bit to address an obvious issue from Email #1 with an obvious solution from email #2. Check out 5 Great Reasons to get an ALM health check  and then to find out more, call 01274 300175 or visit http://www.blackmarble.com/XBoxElfCheck

• Login crash loop

  - by dawmail333

  After about the second/third batch of updates on a fresh install of Ubuntu 12.04, I end up getting stuck in an infinite login loop: I enter my password, screen goes black and shows me the end of the initialisation messages (including things like CUPS initialising), and then the greeter reappears. Kicker is, as I'm using gnome-shell, I just decided to uninstall LightDM, ubuntu-desktop and unity-greeter, using GDM as my manager, and the problem still happens in exactly the same manner. I'm lost even as to where to start looking - Xorg logs, LightDM logs (before I removed it), syslog and dmesg logs have held no unusual information at all. I have a TeX assignment due next week, and reinstalling Ubuntu every time I want to work on it is not going to work (nor is using TeX on Windows ;). Anything else I should try?

• How to play WMV files?

  - by Isaiah Bugarin

  I tried playing a WMV file in VLC and it told me something along the lines of Unable to play WMV3 files. Unfortunately there is no way for you to fix this. When I try to open the same file in MPlayer, it tells me an Internal data stream error occurred. I finally got it to start playing in KPlayer, but it is really sketchy; it's black and white and there's a few random blue lines down the middle of the video. So is there any support for WMV3 files? P.S. the same WMV file plays fine on my PC. A different WMV file plays on Ubuntu fine.

• How can you remove Unity from Ubuntu Netbook Edition

  - by Brad

  In previous versions of Netbook Remix I was able to disable the netbook-launcher and just have a blank desktop. I liked the speed of the Netbook version but not the interface, this worked well for me. However, now with 10.10 and Unity I'm having trouble doing a similar thing. I tried removing netbook-launcher from the startup and tried uninstalling unity. The best result I got was a black desktop with a panel and a non configurable blank white background. Is Unity soo integrated into this version that I will have to just go with the default ubuntu installation?? In the past the default version has been slower then the Netbook version without the interface. Thanks.

  - by jml

  I have a beautiful 27" iMac. I would like to run Ubuntu on it natively, dual-booting with OS X. I have rEFIt installed, and I can boot into the Ubuntu 10.10 CD, kind of. Here's what happens: I select the CD from the rEFIt menu It loads for a while, then flashes up an aubergine screen with a very low-res picture of a human, an arrow and a keyboard It sits there for a while It changes to 80x25 console mode The screen then goes black, as if nothing is displaying to it All the while, the CD is churning away as if something is reading from it. What do I do?

• How can I get wireless working on an HP-Mini 110-3150?

  - by jfmessier

  I just got an HP Mini 110-3150, and booting from an external hard disk with Ubuntu 10.10 works all fine, except that there is no wireless detected. I noticed that the Wireless indicator is red under Ubuntu, but is enabled under whatever Windows 7 I got on it. So, I understand that it may not get detected at all by Ubuntu at startup time, and there is no manual switch that I can simply slide to turn on/off. How can I get the Wireless device turned ON by default at startup time, and is there any special driver I need to install (proprietary or not) to get it working ? Merci :-) Update: When actually installing on the computer, as a new install, the NIC is not detected at first, but upon restarting, I get a notification of a closed driver available for the wireless. Once installed, updated and restarted, it works fine.

• How to fix an annoying ReSharper &ndash; NuGet error

  - by terje

  Originally posted on: http://geekswithblogs.net/terje/archive/2013/10/30/how-to-fix-an-annoying-resharper-ndash-nuget-error.aspxUsing NuGet in Visual Studio together with ReSharper may sometimes lead you into an annoying error where ReSharper indicates your code has an error, but the solution builds just fine. This may happen if you have a set of NuGet packages, and you either just restore them, or delete them on disk and then restore again.  Your code ends up looking like this, note the red missing functions, which comes from the Moq library - which is downloaded from NuGet:   while the Build is still fine, it compiles without any errors: This stackoverflow question gives some different approaches to solve this, but my experience have been that the Resharper Suspend-Resume trick most often solves the issue: In Visual Studio:  Go to Tools/Options/Resharper Press Suspend: When this is done the error markers disappear, since ReSharper now is inactive. Then just press Resume again: This has been submitted to Jetbrains support, ticket here: http://resharper-support.jetbrains.com/requests/3882) , if you want to follow it.

• Does using structure data semantic LocalBusiness schema markup work for local EMD URL's?

  - by ElHaix

  Based on what I have read about Google's recent Panda and Penguin updates, I'm getting the impression that using semantic markup may help improve SEO results. On a EMD (exact match domain) site, that may have been hit, we list location-based products. We are now going to be adding a itemtype="http://schema.org/Product" to each product, with relevant details. However, that product may be available in Los Angeles and also in appear in a Seattle results page. We could add a LocalBusiness item type on each geo page to define the geo location for that page. While the definition states: A particular physical business or branch of an organization. Examples of LocalBusiness include a restaurant, a particular branch of a restaurant chain, a branch of a bank, a medical practice, a club, a bowling alley, etc. We could add use the location property which would simply include the city/state details. I realize that this looks like it is meant for a physical location, however could this be done without seeming black-hat?

• Calling all developers building ASP.NET applications

  - by Laila Lotfi

  We know that developers building desktop apps have to contend with memory management issues, and we’d like to learn more about the memory challenges ASP.NET developers are facing. To be more specific, we’re carrying out some exploratory research leading into the next phase of development on ANTS Memory Profiler, and our development team would love to speak to developers building ASP.NET applications. You don’t need to have ever used ANTS profiler – this will be a more general conversation about: - your current site architecture, and how you manage the memory requirements of your applications on your back-end servers and web services. - how you currently diagnose memory leaks and where you do this (production server, or during testing phase, or if you normally manage to get them all during the local development). - what specific memory problems you’ve experienced – if any. Of course, we’ll compensate you for your time with a $50 Amazon voucher (or equivalent in other currencies), and our development team’s undying gratitude. If you’d like to participate, please just drop me a line on [email protected].

• Can not get to login screen, background starts with terminal prompt only

  - by Doug

  my uncle has Ubuntu on his work PC. Basically I came in to work today, and he had lost his UNITY side bar. I told him start with just rebooting it. He rebooted it... now it does not even get to the login screen. It gets to the background with the word UBUNTU, and the 6 or 7 dots, does it's little loading dot thing... then stops, and a black terminal opens on the top left with the background still in place. Personally, I think he screwed it up himself. He always swears he didn't touch anything, but I know better... Either way, I can't get him back into the desktop to even see if the sidebar is back. He's always screwing around pressing the wrong buttons on the login screen, hitting admin things and such... Any ideas?

• I can't get suspend, hibernate and shutdown to work in Ubuntu 12.04

  - by Fostext

  I recently built a computer with these specs: Asus Motherboard, Intel i3 3.3 GHz dual processor, 8 GB of RAM. I installed 12.04 on a brand new hard drive. I partitioned the hard drive between root, home and swap like I have often read how to do. I cannot get this machine to properly shutdown. I have to hold the power button down now. Although, for the first few days it properly shutdown. I also cannot get the system to hibernate or suspend properly. I have read tons on this and watched many YouTube tutorials on how to fix both, but the computer never wakes up after suspend or hibernate. It just stays on a black screen. Can anyone help? I love 12.04 so far, but these setbacks are making me worried about stability and power management issues. Also, I wonder if it's really bad for the hard drive to force the CPU to shutdown.

• Why are the packages found with apt-get always horribly out of date?

  - by Andrew

  Whenever I use the package manager, it can only ever find really old versions of stuff. Example: sudo apt-get update sudo apt-get install postgresql The best it can do is version 8.4 (3 years out of date). Trying to get a later version, I get: $ sudo apt-get install postgresql-9.1 Reading package lists... Done Building dependency tree Reading state information... Done E: Couldn't find package postgresql-9.1 I experience the same issue whenever I use the package manager, so I usually just download and build things from source. How can I make it find up-to-date software?

• Kicked out when logged in?

  - by acidzombie24

  When i log into ubuntu the screen goes black as it were logging in but then i am back in the login screen. I can login as guest (i should disable that). I can login via ssh. The last time i had no issues was when i used it this morning and the only unusual thing i did was shutdown via ssh (i think i wrote shutdown now) which had ubuntu hang after showing the shuting down screen for many seconds (i kind of assumed it shut down properly since the UI froze as well and it usually takes less time). Whats the easiest way to fix this w/o reinstalling? Its a brand new install and so it probably takes me 10mins to recopy/setup everything so i may just do that -edit- using 12.04

• Are flag variables an absolute evil?

  - by dukeofgaming

  I remember doing a couple of projects where I totally neglected using flags and ended up with better architecture/code; however, it is a common practice in other projects I work at, and when code grows and flags are added, IMHO code-spaghetti also grows. Would you say there are any cases where using flags is a good practice or even necessary?, or would you agree that using flags in code are... red flags and should be avoided/refactored; me, I just get by with doing functions/methods that check for states in real time instead. Edit: Not talking about compiler flags
