• 12.04 - Disable the HUD trigger key [ALT] in Emacs & Terminal

  - by EoghanM

  An answer on How to disable HUD in Unity 2D? points to https://bugs.launchpad.net/unity-2d/+bug/947613 where the ALT key will be made reconfigurable. Apart from emacs usage, I'm reasonably happy with using the ALT key to bring up the HUD. While using emacs though, the ALT key is tapped frequently to invoke commands. Should emacs be special cased with respect to the ALT key? I'm wondering what the situation is with games; surely lots of games repurpose the ALT key for their own use, e.g. to fire a weapon? If so, could the same be applied to Emacs, i.e. prevent the ALT key in emacs from triggering the HUD. Edit: just realized how extensively I use the ALT key in the terminal: a quick tap of ALT+B to move back a word loses focus of the terminal and brings up the HUD. Aghch

• Backtrack 5 R2 Dual-Boot w/Windows 7 No Longer Loads

  - by dstars5

  A while back, I installed Backtrack 5 R2 to Dual Boot on a Windows 7 PC. It worked fine for a while, but now when I try to load it, the screen gets all messed up (tried to get a picture with my phone, but it wasn't working too well). The last line before it freezes says: fb: conflicting fb hw usage: nouveaufb vs VESA VGA - removing generic driver Since it last worked, the only changes I can think of are that the computer is now connected via ethernet cable to the router, and I upgraded the graphics card (to nvidia). Because of the last line, I personally would put my money on the latter, but I still have no clue how to fix this. Can someone help me? Thanks!

• 12.04 sound keeps auto-muting when idle

  - by fali

  I just installed 12.04 on an HP8510W. Everything works fine except for one weird behavior which I have noticed. When ever there is no audio playing, the audio mute indicator on the laptop is on. As soon as I start playing a you tube video the mute indicator turns off and I get sound. Here is my pulse audio output which says that the sink is suspended because it is idle: Welcome to PulseAudio! Use "help" for usage information. list-sinks 1 sink(s) available. index: 0 name: <alsa_output.pci-0000_00_1b.0.analog-stereo> driver: <module-alsa-card.c> flags: HARDWARE HW_MUTE_CTRL HW_VOLUME_CTRL DECIBEL_VOLUME LATENCY DYNAMIC_LATENCY state: SUSPENDED suspend cause: IDLE I tried running alsamixer, but I don't see the auto-mute option.

• MCrypt Module, Rijndael-256

  - by WernerCD

  An outside company is redoing our company Intranet. During some basic usage I disovered that the "User Edit" screens, with the "Password: *" boxes have the password in plain text, with the text box "type=password" to "hide" the password. The passwords are not store in the database as plain text, they are stored encrypted using "rijndael-256" cypher using the mcrypt module. I know that if I encrypt a password with SHA*, the password is "Unrecoverable" via one-way encryption. Is the same of MCrypt Rijndael-256 encryption? Shouldn't an encrypted password be un-recoverable? Are they blowing smoke up my rear or just using the wrong technology?

• Creating a new variable versus assigning an existing one

  - by rwallace

  Which is more common, creating a new variable versus assigning an existing variable (field, array element etc - anything that syntactically uses the assignment operator)? The reason I ask is that I'm designing a new language, and wondering which of these two operations should get the shorter syntax. It's not intended to be a pure functional language, or the question wouldn't arise, so I'd ideally like to count usage across large existing code bases in procedural and object-oriented languages like C, C++ and Java, though as far as I can see there isn't an easy way to do this automatically, and going by memory and eyeball, neither is obviously more common than the other.

• Unable to mount location, Can't mount file

  - by user116008

  I'm a new user to Ubuntu and I have a problem: I had Windows XP in my computer and I had two partitions: C (for system data) and D(for my personal stuff), then, during the Ubuntu installation I chose the Advanced Settings and formated C partition and left D partition intact, went back and chose Install Ubuntu and replace Windows and it installed fine. The problem is that now I open Nautilus and go to Computer, in there it shows my D partition, 640 Hard Disk, but when I try to mount it displays me a message: "Unable to mount location. Can't mount file". I ask you to explain me step-by-step what I need to do because I'm not an advanced user. My computer specs: 2 GiB RAM, Proccesor Pentium(R) Dual-Core CPU E5400 @ 2.70GHz × 2, Graphics Unknow (It's Nvidia GeForce 220 {1GB} or something), OS type 32-bit, Disk 628.0 GB P.S.: My HDD is internal, I'm not using external Hard Drives.

• Can Google Translate's audio files be used in a game?

  - by ashes999

  For my game, I need text-to-speech. Since it's Android, I decided to settle for MP3s, since the range of words spoken is few. For my prototype, I'm using Google Translate to generate the audio since it has awesome pronounciation across multiple languages. But can I use it in production? What if I sell my game for $1 on the app store? All I can find on SE is that the API may be LGPL, and that the licensing page mentions the API is only available for academic research -- nothing more. My usage is a bit different; I'm actually capturing the audio bits and using those instead. I'm curious to know the license for this; I can't find anything with my Google-fu.

• How would you answer this job-interview question?

  - by ahmed

  One of the five people who interviewed me asked a question that resulted in an hour-long discussion: "Explain how you would develop a frequency-sorted list of the ten thousand most-used words in the English language." My initial response was to assail the assumptions underlying the problem. Language is a fluid thing, I argued. It changes in real time. Vocabulary and usage patterns shift day-to-day. To develop a list of words and their frequencies means taking a snapshot of a moving target. Whatever snapshot you take today isn't going to look like the snapshot you take tomorrow or even five minutes from now. Thanking you advance for your answers and consideration.

• How to start embedded development for developing a handheld game console?

  - by Quakeboy

  I work as a iPhone app developer now, so I know a bit of c, c++ and objective c. Also have fiddled with Java and many other. All of them have been just high level application/games development. My final goal is to make a handheld game console. More like a home made NES/SNES handheld console or even an Atari. I have found out about RaspberryPI and Arduino. But I need more information about how to approach this. 1) How Do I learn to pick the best board/cpu/controller/GPU/LCD screen/LCD controller etc? 2) Will learning to make a NES emulator first help me understand this field? If so are there any tutorials?

• Problem with the screen resolution on 12.04

  - by sveinn

  I just installed Ubuntu on my laptop. The screen resolution is stuck in 1024x768. The screen is made for 1280x800. When I run xrandr I get: xrandr: Failed to get size of gamma for output default Screen 0: minimum 800 x 600, current 1024 x 768, maximum 1024 x 768 default connected 1024x768+0+0 0mm x 0mm 1024x768 61.0* 800x600 61.0 1280x800 isn't offered and I get gamma size error. I was going to look into the Xorg.conf file but I couldn't locate it. 1280x800 was displayed in Windows 7 and I think it is being displayed in Grub before Ubuntu starts also. Here are some details about my computer: CPU: Intel atom D2500 1.86GHz Chipset: Intel 945GSE+ICH7M LCD: 14" TFT 16:9 Resolution ratio: 1280*800 Video Card: Intel integrated GMA950 Does anyone know how to fix this?

• Consuming too much power on a Dell 15R

  - by Daniel Davis

  I'm new to Ubuntu, and I've just installed Ubuntu 11.10, and I must say I really like it a lot. I'm getting used to Ubuntu faster than I thought but the only issue I'm having is the power consumption. I have a " dell 15R with BIOS a07" and I uninstalled Ubuntu 11.04 because of some glitches I hated. None of those appear on this Ubuntu but now my computer discharges way too quick. when I check the power icon, it states that I have like 3:45 min remaining, which is fairly the same as what win7 and Ubuntu 11.04 used to tell me but 15 min later I check again and it gives me only 1:15 min remaining. Also, my computer seems to get a lot hotter than it used to. Is there more options to control the power usage on my laptop?

• Is it better to cut and store all sprites needed from a spritesheet in memory, or cut them out just-in-time?

  - by xLite

  I'm not sure what's best practice here as I have little experience with this. Essentially what I am asking is... if it's better to get your single PNG with all your different sprites on it for use in-game, cut out every sprite on startup and store them in memory, then access the already-cut-out sprite from memory quickly or Only have the single PNG with all the different sprites residing in memory, and when you need, for example, a tree. You cut out the tree from the PNG and then continue to use it as normal. I imagine the former is more CPU friendly than the latter but less memory friendly, vice versa for the latter. I want to know what the norm is for game dev. This is a pixel based game using 2D art. Each PNG is actually an avatar's sprite sheet with each body part separated and then later joined to form the full body of the avatar.

• Windows gets progressively slower over time, why doesn't Ubuntu?

  - by William

  I, and many other previous Windows users notice that the computer seems to get progressively slower over time. I bought a leapfrog crammer only to find it installed process that sat there waiting for me to plug the crammer in so it could run the software. It took up three percent of the CPU twenty-four seven, seven day a week! This is one of the main reasons I left Windows. But, Ubuntu doesn't seem to slow down over time at all. Does Ubuntu allow programs to install background programs like the leapfrog crammer did to sit there like a leech and suck away at resources? Could someone explain why Windows tends to get slower over time, and is Ubuntu vulnrable to this too? Thanks for any help, this is puzzling me.

• Using allocators for different systems

  - by chadb

  I am going over the memory architecture for my game and even though I know my memory budgets may not be final, I at the point where I can start using them in a general sense. I know that I will need several allocators (for systems such as audio, rendering, etc) but I am unsure of how they will be accessed. I do not use singletons, so I can't just have something such as AudioManager::GetInstance().get_allocator(). Instead, I need to find a different method of usage but I am not sure of how. How can I store and call my allocators needed for several different systems over engine in an efficient manner?

• Flash 10.1 est là : accélération matérielle et 32 failles colmatées au programme

  Mise à jour du 11/06/10 Flash 10.1 : accélération matérielle et 32 failles colmatées Flash 10.1 est là. Cette nouvelle version de Flash s'accompagne de l'arrivée de l'accélération matérielle et de la correction de 32 failles de sécurité. La première innovation devrait faire taire, du moins en partie, les critiques sur les performances de la technologie d'Adobe. L'accélération matérielle permet de lire les vidéos (H.264) en utilisant les ressources de la carte graphique (GPU) et non plus du CPU. Résultat, une lecture plus rapide et fluide, et un processeur moins impacté par l'utilisation du player. Tout ceci se passe sur le papier. E...

• Oneiric is freezing. Need help diagnosing and filing a bug

  - by mlissner

  Six months ago, I bought a new Sandy Bridge CPU and built myself a nice desktop machine. Until now it hasn't worked...at all. I finally have gotten it working now that Oneiric is released, but it freezes every so often, making it little more than a semi-functional temptation. What happens when the system freezes is: the music I have playing enters into about 5s loops. SSH fails the monitor freezes the mouse freezes the keyboard fails The only way to fix it is to do a hard reset...and that sucks. I'd love to at least figure out the source of the freeze so I can file a bug. I've looked in dmesg, kern.log, and the X.org logs. Nothing interesting is any of them. Since SSH fails, I'm convinced it's not an X crash: https://wiki.ubuntu.com/X/Troubleshooting/Freeze Anything else I can do?

• Why does the BADSIG/"Untrusted sources" error recur forever?

  - by Jeff McMahan

  On at least a dozen occasions, I've spent 2-3 hours figuring out how to get Ubuntu 11.10-12.10 to either update or acquire software from software center, or both. I want to fix whatever is causing the BADSIG problem once and for all; I've wasted so much time trying to get this to work well enough that I can rely on it, but the same problem comes back after a couple weeks of normal updates and software center usage. Don't refer me to a standard posted solution on the web---whatever it is, I've used it more times than you have. The question isn't whether I can get it to work right this afternoon. I can. The question is what is causing the problem to recur regularly across 3 releases. Notice: I use this computer 4-5 hours per week and I do little on it. PDFs, Latex, FireFox, Mendeley, and that's it. I don't constantly install new software, and I don't fiddle with things unnecessarily.

• Xubuntu fails to stay awake when the machine is under load

  - by Alex

  I have the following problem with a fresh install of Xubuntu 12.04: I set up power management options so as to send the machine to sleep after it's been idle for a while. My intention was to have it finish some lengthy numbercrunching and then fall asleep late at night when nobody's present to shut it down. What actually happened, however, is that the machine goes to sleep whenever the desktop session has been idle for the specified amount of time, and it does not seem to care at all about CPU load, and I had to disable sleep altogether. Is there any way to fix this?
