• Is there now any way to convert mp3 files to m4a or aac 192kbit?

  - by piedro

  Since about two years now I am trying to find a way to convert high quality mp3 files to m4a or aac files with a fixed bitrate 192k. Please don't suggest using another format - i thought this through as far as it goes. The problem here is: ffmpeg obvioulsy can't convert to a higher bitrate than 152k. Even when it says it does so the resulting files still have 152k instead of 192k. ffmpeg also has/had a bug not writing the bitrate into the audio file tags which means when testing you have to calculate the bitrate manually by dividing the filesize by the length of the audio in seconds (resulting in 152k - see above) choosing faac as converter gets me the same results other programs don't work reliably (see this thread Howto convert audio files to *.m4a? I know that this is not an original new problem but I am wondering if there is still no way to convert with ubuntu/kubuntu 12.04 after a lot time passed and I can't find some of the bug issues mentioned in the other thread anymore. So: Is there a solution after all?

• Xrandr settings don't stick; bash script fails; Nvidia; disper doesn't work

  - by bcmcfc

  I have an Nvidia graphics card. Yeah, I know. This might have to change soon. I am trying to get the resolution to set correctly on my second monitor, which is a VGA monitor with a native resolution of 1440x900. I have set up this bash script which doesn't work: xrandr --newmode "1440" 106.50 1440 1528 1672 1904 900 903 909 934 -hsync +vsync xrandr --addmode -display VGA-1 1440 xrandr --output VGA-1 --mode 1440 It outputs: xrandr: cannot find mode 1440. It has worked previously when running the commands individually but after a restart it fails. I've also just installed disper as per this question but have no idea how to use it - the help suggests the command: disper -d VGA-1 -r "1440x900" should work, but it does not. It just outputs the help text, suggesting something is wrong but not saying what. Is there any way to get these horrific Nvidia drivers working properly with a resolution that is not detected by the tools?

• Ubuntu 12.04 shut down freezes

  - by sam

  I am using Ubuntu 12.04 for last one month without any problem. It was upgraded from Ubuntu 10.10. Recently I needed to replace my hard disk. After replacement I installed Windows 7 and Ubuntu 12.04 on the system. For some days it went ok, but now shutting down from Ubuntu is causing problems. It freezes on the text screen saying acpid=exiting checking for running unattended upgrades. After that I waited for a long time, but it didn't go off and I had to hit ctrl+alt+del to restart the system and booting from Windows and then shutting down from there. This happens every time I shut down my system from Ubuntu. I have seen many posts regarding the same kind of issues but none of the solutions reported there helped me out.

• Ubuntu 12.10 with kernel 3.5.0-18 failing to boot

  - by Chaitanya

  I had 12.04 with kernel 3.0.2. Today I have updated my system and got 12.10 with kernel 3.5.0-18. Now when I boot my machine with 3.5 kernel, it starts until the page where I enter my password. Within seconds, I get a page with looooong list of some commands or list. I can't take screen-shot of that. It looks something like: [1.2234978942837]kjsahfa;lsfksld;fkjsf;owieurwirejw/rnw;erkjwelrjw2309480432 [1.3294823498230948]as;lfjsf;iuwrijrwjlkerjw;rekwer;lkwjre;lkjRIJWEORIWE'JJA; Luckily, in my boot page, I have 3.0.2 kernel also. When I boot with 3.0.2 kernel there is no problem. But when I boot with 3.5.0, it throws that weird error. I wont be able to do anything at that time. None of the keys work. I have to forcibly shutdown the machine and restart with 3.0.2 kernel. Please help.

• Black screen after installing Ubuntu 11.10

  - by Abbas

  I downloaded Ubuntu 11.10 one week ago and burned it to a CD. I installed it on my system which has a 1.5 TB hard. It installed successfully and I clicked on the restart button. The computer restarted and I chose the first option, which was to load Ubuntu. A black screen would appear with a cursor in top left hand side and I think the system was hung. I repeated this process by erasing the last Ubuntu install but I faced a similar problem. Can anybody help me?

• Shader inputs in a general purpouse engine

  - by dreta

  I'm not familiar with SDKs like Unity or UDK that much, so i can't check this off hand. Do general purpouse engines allow users to create custom uniform variables? The way i see it, and the way i have implemented it in an engine i'm writing to learn 3D, is that there is a "set" of uniforms provided by the engine and if you want to write a custom shader then you utilize uniforms you need to create a wanted effect. Now, the thing is, first of all i'm not an artist, second of all, i didn't have a chance to create complex scenes yet. So my question is, is it common practice to define variables that the engine provides and only allow the user to work with what they're given? Allowing users to add custom programs and use them where they want is not hard, but i have issues imagining how you'd go about doing the same for uniforms.

• "Time Control" in a 2d Platformer

  - by Woody Zantzinger

  I am making a 2d platformer where the player can press a button, and restart the level, only their previous character will also run the level at the same time, like they are traveling back in time. I know other games have done this before, and the way I have thought of doing it is to make the game character have a set of actions (Idle, Jumping, Walking Left etc.) and then detect changes in those actions and log them into a list along with the game time. So then when I need the character to run the level again on its own, I can just go through the list changing its actions at the right time. Is this the best way to do it? Does anyone have any experience in this? Thanks.

• Flashing task bar(firefox) in lxde panel and ubuntu internal error

  - by arroy_0209

  I have upgraded from ubuntu10.04 to 12.04 and installed lxde. The panel is now customized according to my convenience. The problem is there was a default checked option for "Flash when there is any window requiring attention" in Task bar(window list) and now when I run firefox, at times the concerned bar in the panel window list starts flashing but it is not clear exactly why at that moment firefox requires my attention. Normally this happens after I download some files (pdf files) and keep using firefox. The only solution I have found is to quit firefox and even after that I receive this message "Sorry, ubuntu12.04 has experienced an internal error. If you notice further problems, try restarting the computer." As usual I report the detailed message to ubuntu as suggested and finally restart the computer. So there are two problems, first, exactly why firefox needs my attention at times and second, why immediately after this, ubuntu experiences an internal error. Please suggest what I should do.

• The best AutoCAD 2010 Ubuntu alternative?

  - by onvas

  I'm looking for the best AutoCAD 2010 alternative for Ubuntu. Wine's support for the 2010 version isn't polished so I'm looking for Linux based similar programs. I know that this can be subjective so I'd like to know what's the best Ubuntu alternative which has the most similar, and significant features as that of AutoCAD 2010? I'm not familiar with the program because I'm researching this for my sister who is studying Aeronautical Engineering. Any help is appreciated. I'm using 12.04 64-bit on my ThinkPad R61i with 3.8GB memory and 160GB hard drive.

• How to remove Ubunto from boot screen?

  - by Alaa M.

  I tried to install Ubuntu 14.04 on my Windows 8, and in the installation wizard I chose "Help me boot from CD". Now I have something like this when I restart the computer: http://i.stack.imgur.com/HxDQr.png If I click Ubuntu I get an error about a missing file (wubildr.mbr). I found a solution here. But that's not my concern now. I don't know if that means I have Ubuntu installed on my computer now or not, but I wanna delete it from the boot screen. I figured that I need to delete its partition, so I went to Disk Management and found the following: http://i.stack.imgur.com/W0oP4.png My question is: which one should I delete?

• What are the factors that determine the default frequency of a shader call?

  - by user827992

  After i have been played for some days with various vertex and fragments shaders seems clear to me that this programs are called by the GPU at every and each rendering cycle, the problem is that I can't really quantify this frequency and I can't tell if is based on some default values or not because I don't have a big collection of hardware right now to do extensive tests. For what i know the answer could be really trivial like "it's the same of the refresh rate of your monitor", but i would like some good answers on that to be clear on this. For instance looks really odd to me that all the techniques used to control the amount of FPS that i have seen until now uses a call for the OpenGL function glutGet(GLUT_ELAPSED_TIME) to retrieve a value in ms about when the rendering started but I have to relies on the CPU to do the math. Why I can't set an FPS value in OpenGL if OpenGL clearly has a counter and a timer/clock? PS I'm referring to OpenGL 3.0+

• Suggestions on Calculating Advertising Rates [closed]

  - by Jonathan Wood

  Possible Duplicate: How do I set a price for advertising on my website? I recently launched a new developer website, Black Belt Coder. The site is only seeing about 150 visitors per day but, given that it's only been live two months, I feel I'm off to a good start. I'd like to start monetizing the site as soon as possible but consider AdSense and other programs largely a waste of time. I'd like to deal directly with the advertisers but have no idea what to charge. Are there any guidelines for determining advertising rates based on visitors or page views? I don't expect to do PPC. I want to charge a the time period for banner ads, knowing that advertisers will be keeping an eye on the number of clicks.

• How to better start learning programming - with imperative or declarative languages?

  - by user712092

  Someone is interested in learning to program. What language paradigm should I recomend him - imperative or declarative? And what programming language should he start with? I think that declarative because it is closer to math. And I would say that Prolog might be the best start because it is based on logic and programs are short. On the other hand at school we started learning from imperative languages and I am not sure whether there is a benefit to start with them instead of declarive ones. Thanks. :)

  I have icedtea6-plugin installed on my Ubuntu box. The weird thing is, when I am browsing the internet, certain website are able to use the Java and some websites are not. For instance, I am able to log in to my bank at nordea.dk. They use a Java applet to authenticate the user. But when I try to use keepvid.com, it says "Loading Java Applet". And then after a minute or two it says "Error: Please click here to download Java. If you already have Java, please restart your browser and try again." The thing is I've restarted my computer, closed and opened my browser(chromium) and none of it seems to help. Could someone please point me in the right direction to solve this problem? Thanks.

• I can't click on some things and other problems

  - by Ruben

  I have some issues with my Ubuntu 12.04 . When I open Ubuntu Software Center, the program opens and than just disappears just when it is opened. My Ubuntu 12.04 won't install any updates because of this error in the picture. Worst of all: I can't click on anything except for programs that from Ubuntu: for example I can't browse the internet via Firefox or Chromium... I can't click on folders. I can't click on things in my Thunderbird mail program. But I can click on Update manager for example... It is just clicking that doesn't work, when I try 'clicking' something with using the tab-button and enter I can click on something - in every case. But that's just too annoying to do. Oh sorry guys I had some screenshots that illustrate the problems, but I can't get them off the 'problem pc ubuntu 12.04' about which I am talking... it's so sad
