• How to close lid without triggering standby one time only

  - by Ian Mackinnon

  Related: How can I tell Ubuntu to do nothing when I close my laptop lid? I have my laptop set to activate standby when I close the lid. I want to keep this as the default for both battery and AC power. But occasionally I want to close the lid without triggering standby (eg. while just listening to audio). Is there someway I can tell Ubuntu, "I'm going to close the lid now. Don't stand by this time", without altering the defaults (because I almost always forget to change them back).

• Check for bodies within a specific circle in Box2D

  - by ltjax

  I'm trying to find positions to insert new bodies into my world. For that, I'd like to have a "free" spot where this body wouldn't overlap with anything else. So my plan was to sample "random" positions and check whether they overlap with my "potential" new body. Since my bodies are always circular, I'd need to test within a given circle. So far, the only way to use box2d for this seems to use b2World::QueryAABB around my circle and manually doing an overlap test with all the fixtures it gives me (Box2D doesn't event seem to allow me to tap into its overlapping tests?!). It seems to me like Box2D should already provide such functionality - is there a way that lets me do this without reinventing most of the wheel again?

• How to Delete/Disable gnome panels. No existing solutions working.

  - by Alan Peabody

  I would like to remove gnome panel completely. I spend most of my time in a (tmux) terminal or a browser. Synapse and a small hidden AWN panel fit the rest of my needs. I have tried all recommended solutions including this (found it a few places): How to delete Gnome Panel? However it always comes back at log in. I have tried changing the required components panel to avant-whatever as well as to empty. I have tried setting them both as default (right click set as default). Right now I just have the last panel set to transparent and auto hide, but it still tends to be annoying. What do I need to do to get rid of this damn thing?

• Skype webcam not working in 12.04

  - by To Do

  I have a logitech quickcam messenger that was working fine until I upgraded to Ubuntu 12.04. I had to use preload v4l hack but since then it always worked for three consecutive ubuntu versions. Now, when I start the webcam during a call, it works for a few seconds, then it freezes, sortof resets and starts updating the image every 5 seconds, like a slide show. If I go to options and test the video it works fine. The webcam works fine as well with google talk. Does anybody have the same problem?

• Will making players pay a virtual currency before entering a match discourage them from playing?

  - by Bane

  I'm making a multiplayer match-making game, and by my current design, people will need to pay a small fee before joining a match. At the end of the match, the team that won will get the money. That will be a virtual currency, but still, will it discourage people to enter matches? I introduced it to make the matches matter more, because there's always a fear that you will loose your investments. I'm not talking about anything big here, but even a small amount might have a similar psychological effect as a bigger one.

• Good resources for JavaScript 2D game programming?

  - by DJCouchyCouch

  As an exercise, I've decided to look into JavaScript for game programming. While it's far from being the best language for that, I do like the idea that it's cross-platform and it's always available as a web page. So I thought I'd see what I could do with it. Specifically, I'd like to make a 2D tile-based game of some kind. Where can I find resources to do that? I'm sure this question's come up before, but I can't find any reference to it.

• Audio codec consuming high battery power

  - by Vamsi Emani

  My powertop reports this for the two audio codec components. 4.85 W 100.0% Device Audio codec hwC0D3: Intel 4.85 W 100.0% Device Audio codec hwC0D0: Realtek I think 10 W for audio is too high. Can somebody please suggest me a way to reduce the power consumption? It'd be nice if someone could educate me on this, I have an idea about codecs in general but I have no clue about their internals? Why is it that these two components keep running always even when I am not listening to audio?

• PHP and performance

  - by Naif

  I always hear that PHP is for medium and small websites whereas .NET and Java for enterprise applications. My question is about PHP. Why is PHP not a good option for enterprise web applications? Is it because if the web application becomes bigger then PHP will be slower as it is an interpreted language? I know that corporate world will choose .NET or J2EE because of the integration with their products and because of back end services, etc. However, if we just have PHP for building sites and web applications then how can we use it to perform well with big sites? In short, Is there a relationship between the performance of PHP and the size of the website? What are the factors that make PHP not appropriate option for big sites?

• What are the packages/libraries I should install before compiling Python from source?

  - by Lennart Regebro

  Once in a while I need to install a new Ubuntu (I used it both for desktop and servers) and I always forget a couple of libraries I should have installed before compiling, meaning I have to recompile, and it's getting annoying. So now I want to make a complete list of all library packages to install before compiling Python (and preferably how optional they are). Off the top of my head I can remember these: build-essential (obviously) libz-dev (also pretty common and essential) libreadline-dev (or the Python prompt is crap) But I know there are many more. Please tell me and I'll update.

• Beggining OpenGL vs beggining DirectX and some question about the philosophical difference between them

  - by jokoon

  I'm begginning with Direct X at school, and my teacher said it was harder to begin with than OpenGL, but I read several things that in fact, Direct X was more advanced than OpenGL in terms of recent graphic cards features. Since I'm far from wanting to do top notch effects, which can already be implemented with existing engines and/or shaders, I wanted to know your opinion: Can OpenGL be considered like a more basic, KISS, hardware agnostic, graphic library to just do 3D with acceleration, and consider DirectX like a top notch, game-oriented graphic API that will always support the next-gen 3D chips ? Citation from wikipedia on http://en.wikipedia.org/wiki/Id_Tech_5 : John Carmack mentioned in his keynote at QuakeCon 2007 that the id Tech 5 engine will not be using the DirectX 10 API. I don't want to seem like I'm minding open source because Carmack does and because he is famous, it's just that android and iPhone are out there, and Direct X doesn't seems to me to be the necessary API to know, since Windows supports OpenGL, and since the 360 is just a console among other consoles.

• Alachisofts new version of NCache announced at TechEd !

  Before coming to Microsoft I owned a consulting company that specialized in solving performance and scalability problems in web applications.

• Bluetooth pairing works in 10.10 but not in 11.04

  - by Nathan Haines

  My laptop, a Compaq Presario V2000, has a built-in Bluetooth module that has worked well since at least Ubuntu 8.04 LTS. I use it to pair with headphones and a mouse. These both worked great in Ubuntu 10.10 (and still do with a live CD) but I cannot pair to any Bluetooth device in Ubuntu 11.04, even from a live CD. I can see the Bluetooth module in lspci and when I try to set up a new device from the Bluetooth indicator my computer detects all Bluetooth devices around me but pairing always fails. At the moment I'm most concerned with getting my Microsoft Wireless Notebook Presenter Mouse 8000 paired. Relevant output of lspci: Bus 003 Device 002: ID 03f0:011d Hewlett-Packard Integrated Bluetooth Module

• How to Access Boot Options 12.04 Live USB

  - by Ryan Kampmeier

  I'm attempting to install 12.04 on my computer but booting from my USB drive results in a blank screen. This has happened since 10.04 and has always been fixed by putting nomodeset in the boot command, but now I can't access the boot options with F6 for some reason. How can I access the boot options? I booted into the live image on a different computer and it worked fine. I'm sure it's because of my Nvidia graphics. When I boot into the live image it shows a small gray box in the lower left corner of the screen and that's it. I can't edit the boot options or do anything else. Thanks in advance.

• How to make "Chameleonic Ambiance Script" select a lighter hue for dark wallpapers?

  - by Nirmik

  I just started using an amazing script that makes the default "Ambiance" theme use that selected color. More details can be found Here I find this really amazing. But with my wallpaper being as shown below, the selection color, progress-bars color as after running the script are too dark (that can be seen in the following screenshot). I've learnt that what is done is the average color from the wallpaper is selected and then its tint is used (which is always a darker tint). So can I make this algorithm or whatever select a lighter tint of the average color?? Or can it be made to select the lightest color instead of the average color from the wallpaper??

• How do I calculate a SWAP partition?

  - by Dean Howell

  Since the late 90s I've always understood that it is best practice to allocate twice the amount of physical RAM as swap space. I just received my new laptop in the mail and it came with 6GB of RAM. In a separate order I had 16GB of RAM to replace the preinstalled. I didn't have the right torx driver to get to the RAM in this machine, so I installed Ubuntu and manually set a 16GB partition for swap. 32GB seemed a tad excessive... Did I make the right choice? Would my machine perform better if there was no SWAP at all?

• When to reply 400 Bad Request

  - by KajMagnus

  According to www.w3.org, a Web server should reply with status code 400 Bad Request if: "The request could not be understood by the server due to malformed syntax. The client SHOULD NOT repeat the request without modifications" Does that mean only request that violates some HTTP spec? Or does it include a request that my particular Web app thinks is broken? When would you reply 400? For example, if my Web app expects a query string to always include a "function=..." parameter, would you reply code 400 Bad Request or 403 Forbidden? (403 means that "The server understood the request, but is refusing to fulfill it.")

• Using Mock for event listeners in unit-testing

  - by phtrivier

  I keep getting to test this kind of code (language irrelevant) : public class Foo() { public Foo(Dependency1 dep1) { this.dep1 = dep1; } public void setUpListeners() { this.dep1.addSomeEventListener(.... some listener code ...); } } Typically, you want to test what when the dependency fires the event, the class under tests reacts appropriately (in some situation, the only purpose of such classes is to wire lots of other components, that can be independently tested. So far, to test this, I always end up doing something like : creating a 'stub' that implements both a addXXXXListener, that simply stores the callback, and a fireXXXX, that simply calls any registered listener. This is a bit tedious since you have to create the mock with the right interface, but that can do use an introspective framework that can 'spy' on a method, and inject the real dependency in tests Is there a cleaner way to do this kind of things ?

• Automatically zoom out the camera to show all players (XNA)

  - by user36159

  I am building a game in XNA that takes place in a rectangular arena. The game is multiplayer and each player may go where they like within the arena. The camera is a persepective camera that looks directly downwards. The camera should be automatically repositioned based on the game state. Currently, the xy position is a weighted sum of the xy positions of important entities. I would like the camera's z position to be calculated from the xy coordinates so that it zooms out to the point where all important entities are visible. My current approach is to: hw = the greatest x distance from the camera to an important entity hh = the greatest y distance from the camera to an important entity Calculate z = max(hw / tan(FoVx), hh / tan(FoVy)) My code seems to almost work as it should, but the resulting z values are always too low by a factor of about 4. Any ideas?

• All video thumbnails fail to be generated

  - by Forage

  Not a single video thumbnail is being generated and shown in Nautilus. The folder ~/.cache/thumbnails/fail/gnome-thumbnail-factory/ keeps getting filled for all of them. I tried removing all the thumbnails from the folder, reinstalling the gstreamer-plugins-... and totem packages, changing the thumbnail settings (Always, 4 GB) in the Preview section of the Nautilus preferences. All to no avail. Some recommend to install packages like libxine1 and ffmpegthumbnailer but this didn't not solve it either. There used to be an .xsession-errors error log file generated in the home folder in previous version of Ubuntu but that doesn't seem to be the case any more. I'm running Ubuntu 12.10 GNOME remix (x64) with the GNOME3 ppa packages installed. What could be the cause of the problem and how can I fix it?

• Turning off the backlight on the console

  - by Albertas Agejevas

  I'm using an IBM Thinkpad X21 as a 3G router. It's running a server install of lucid. The laptop has the lid up most of the time. There is no X, just a plain console. The colsole blanks itself, but the LCD backlight is always on. The graphics chip is ATI Technologies Inc Rage Mobility P/M AGP 2x (rev 64). The following modules related to the framebuffer are now loaded: $ lsmod | grep fb fbcon 35102 71 tileblit 2031 1 fbcon font 7557 1 fbcon bitblit 4707 1 fbcon vga16fb 11385 1 vgastate 8961 1 vga16fb Can I make the LCD backlight turn off when the colsole is unused and have it turn on automatically when needed?

• Applying prerecorded animations to models with the same skeleton

  - by Jeremias Pflaumbaum

  well my question sounds a bit like, how do I apply mo-cap animations to my model, but thats not really it I guess. Animations and model share the same skeleton, but the models vary in size and proportion, but I still want to be able to apply any animation to any model. I think this should be possible since the models got the same skeleton bone structure and the bones are always in the same area only their position varies from model to model. In particular Im trying to apply this to 2D characters that got 2arm, 2legs, a head and a body, but if you got anything related to that topic even if its 3D related or keywords, articles, books whatever Im gratefull for everything cause Im a bit stuck at the moment. cheers Jery
