• My laptop overheat on ubuntu 13.04

  - by Sina

  Overheating maybe is exaggerating word, but it's temperature is more in comparison with windows. My Graphic Card has failed for 2 time and I've paid money for each time. The problem makes me disappointed of keeping on ubuntu. Whenever I want to install "nvidia-current" my resolution becomes too low in screen and sometimes it just shows a dark screen. Is there any other Linux distribution which be more compatible with Hardware, specially Graphic Card? My Laptop is Dell Vostro 1510. And once This problem happened in 12.04 and another time days ago :(

• Roll Your Own Flexi-Ties to Secure and Store Frequently Used Cables

  - by Jason Fitzpatrick

  If you’re looking for an easy way to hang up or tidy frequently used cables, these DIY soft ties are durable, resuable, and easy to make. Soft ties ties are metal wire ties coated in rubber; people use them for everything from securing computer cables to shaping garden plants. Instructables user Bobzjr wanted a lot of them but couldn’t find anyone that sold bulk roles of the soft tie material. To that end he did a little exploring at the hardware store and found the perfect combination of wire and rubber to roll his own. Hit up the link below for more information on his DIY soft tie project.

• hPalm and a web-centric strategy

  The acquisition battle has come and gone, and it’s HP that’s become Palm’s new owner. In general this news has been greeted withgladcries,despite (or maybe because) it was so unexpected. In general everybody assumes that the marriage of Palm software and HP hardware will be a good one, and that HP will also release a webOS-based tablet device.However, there’s an interesting dissenting opinion on VisionMobile (a blog I highly recommend, by the way). Guest author Michael Valukenko sees few synergies...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

• How can I fix intermittent iSight camera functionality on a Macbook Pro 5,2?

  - by Mmmm

  I have a Macbook Pro 5,2 laptop dual booting OSX and Ubuntu. The built-in iSight video camera works only sporadically. By that I mean that sometimes if I boot and try to use the camera it does not work (most of the time) but other times it does. I don't have good repeatable data regarding when it does vs. when it doesn't other than to say that it always seems to work right after I upgrade to a new Linux kernel with the Update Manager and reboot, but then eventually stops working again until I upgrade the kernel again. That is hard to test repeatably, so it's hard to know for sure that that is the case. This has happened consistently with every version of Ubuntu from 10.10 through 11.10. I can get around this by booting into the OS/X partition, since all of the hardware obviously works perfectly on that side of things, but it would be great if I could remain in Ubuntu and do the same thing. Thanks in advance for any inSights.

• Microphone problem in Ubuntu 11.10

  - by Teja

  I am using both Windows 7 and Ubuntu 11.10 on a single system with the same hardware. While I'm making call through Gmail or Skype my voice is audible to others while I'm on Windows 7, but while I'm on Ubuntu 11.10 it's not audible to others, but I am able to hear their voice. But while I'm playing music on Ubuntu along with a call, the others are able to hear the music, but my voice is not audible for them. Please give me a solution for this and tell me where I can change the microphone settings on Ubuntu 11.10.

• How do I increase the touchpad sensitivity on Acer Aspire One 532h?

  - by Yossi Farjoun

  I got a cheap netbook and put ubuntu on it without even booting into the windows it came with. I am now slightly regretting it since the trackpad is very annoying, it only registers when I press quite hard on it, and even then the motion is so slow that I must drag me poor finger 3 times to get the pointer to move up or down that tiny screen. OK. enough rant. now business: I went into the setting and increase sensitivity and acceleration to high. No difference. the behaviour did not change at all. So now my questions are: Is this a hardware problem? Is there a program I can run to see what input the trackpad is receiving? so I know if it can, in theory, read the light touch and not only the heavy, sandpaper-your-fingertips-off touch? is there some manual setting that the system might not be setting correctly and which I could change from the terminal?

• How to play many sounds at once in OpenAL

  - by Krom Stern

  I'm developing an RTS game and I would like to add sounds to it. My choice has landed on OpenAL. I have plenty of units which from time to time make sounds: fSound.Play(sfx_shoot, location). Sounds often repeat, e.g. when squad of archers shoots arrows, but they are not synced with each other. My questions are: What is the common design pattern to play multiple sounds in OpenAL, when some of them are duplicate? What are the hardware limitations on sounds count and tricks to overcome them?

• How to configure ubuntu for lightweight low-memory usage?

  - by augustin

  I just upgraded an old, secondary computer to the latest Kubuntu (10.10). It seems the effort was a bit too much for the hardware and one 512MB memory module died. I tried to take it away, clean the connectors, put it back several times, but to no avail. Until such a time I can find a second hand DDR memory module, I am left with a meagre 256MB RAM, which is below the official requirements (384MB) to run Kubuntu/KDE. Indeed: the computer constantly swaps the memory, making everything painfully slow. Since Kubuntu is already installed and I use it on all my computers (and I want to keep KDE for when I really need it), how can I configure ubuntu to squeeze out every bit of unnecessary memory usage? This is a secondary computer but still very useful. We use it mostly for web browsing. A "lightweight" tag is missing.

• What does a media server need?

  - by DeaDSouL

  I want to buy a new PC to be used as a media server that streams HD movies, music to any wireless device on my network (laptop, desktop, TV, etc.). I was wondering about the PC hardware's specifications that I need to have so that it can work just fine? (It will be wireless) Is there any tutorial showing how it could be done? And the security - how can I secure it? As well as I need it to to host my emails. I mean I have many emails. And sometimes I'm using desktop, sometimes laptop.. so is it possible to make the server store a copy of my emails, attachments, all sent items (whether they were from desktop or laptop)?

• Steps to rebuild gspca_kinect driver module?

  - by Bobby Ray

  I recently purchased a Kinect for Windows and quickly discovered that the camera drivers included in linux kernel 3.0+ aren't compatible with the Kinect for Windows hardware revision. After looking at the source code it seems like a tiny modification is all that is required for compatibility, so I've been trying to recompile the driver - to no avail. I've been referring to this article and this one as well, though they are a bit outdated. When I try to compile the module, I get an error because the header file "gspca.h" can't be found in the include path. I located the missing header in my filesystem, but the file itself is empty. I've also tried downloading the kernel source (3.2.0-24-generic), which allowed me to compile the module, but when I load the module I get an error. -1 Unknown symbol in module Is there a standard way to go about this without first building the kernel? Will building the kernel ensure that I can build the module? Thanks

• How can I fix my problems with fonts in Firefox?

  - by snostorm

  Ever since I reinstalled Ubuntu a few hours ago, I've experienced major visual artifacts with smaller font sizes in Firefox. The fonts end up looking like this: Or even like this: This only occurs in Firefox; other applications are unaffected. It also occurred on the LiveUSB I used for installation, making me suspect a hardware or driver issue. The output of lshw on my computer is here: http://pastebin.com/LnSt6veT. Any idea what might be causing this, or how I can fix it? ... and "Use Google Chrome" is not a valid answer. ;)

• Determining an application's dependencies

  - by gpuguy

  I have developed an application using Windows Forms in C++ (IDE MS VC++ 2010). Some parts of the application also use MFC, and OpenCV. I want to send the application to my cleint for interim testing on his own machine. I have not developed any installer for the application, so I will be sending him an .EXE file. I want the client to not face any difficulties in replicating the environment, and therefore not lose any time. Can somebody suggest me what software (such as MS VC++ Runtime, .NET Framework, Windows SDK, etc.) should be installed on the client's machine for successfull testing of the application? Note: The OS (Windows 7) and hardware are exactly the same on both sides.

• Broadcom bcm4311 rev2 Full disabled on battery

  - by Antonio BG

  Ok this is my problem... My problem begins while ago when I installed ubuntu 10.10. (is the same with 11.04,11.10...) My wireless card is disabled if the power cord is unplugged, and the only way to fix this is rebooting my pc WITH the power cord plugged and if I use lspci command, it doesn't show me the wireless card. is like if I've removed the wireless board from my laptop port. I've searched a lot of solutions for bcmw4311 issues, but none of them fix my problem because when apply one of the fixes, if I unplug the cord, my wireless card it just gone away... I have dual boot on my pc(w7,ubuntu), I've tried with full installation just to see if this is the problem, but not, is the same. On windows all work correctly with and without power cord.. so this is not a hardware problem, is more like a kernel problem. anyway I can use wireless with power cord plugged, but c'mon this is a laptop not a desktop pc XD haha any help is welcome

• Industry average percentage of dev salary spent on tooling? [on hold]

  - by RationalGeek

  I'm trying to budget for my dev shop and compare our budget items to industry expectations. I'm hoping to find some information on what percentage of a dev's salary is generally spent on tooling, both hardware and software. Where can I find such information? If instead there is a source that looks at raw dollars that is useful, too. I can extrapolate what I need from that. NOTE: Your anecdotal evidence from your own job will not be very helpful. I'm looking for industry average statistics from a credible source.

• new hard drive on Dell Adaptec 2610SA 6 port SATA RAID PCI card

  - by Ragnarok85

  I have a Dell Adaptec 2610SA 6 port SATA RAID PCI card with 3 hard drives on it and everything works fine. I plugged another hard drive to it and the system (Ubuntu 12.04, 64 bit) seems not to recognize it. Strange thing is that, as happened in the past, if I re-install the system, it recognizes the new hardware plugged to RAID card. Of course I don't want to re-install ubuntu each time I plug a new hard drive on my RAID card. Any idea? Thank you in advance

• How to render Minecraft on the GPU?

  - by l0b0

  Hardware: Intel i7 AMD Radeon HD 6970 SSD with plenty of space 6 GB RAM Software OpenJDK 6, 7, and Oracle Java 7 (reproducible with all three) AMD Catalyst 12.8 and open source driver (reproducible with both) Ubuntu 12.04 x86_64 and older Minecraft 1.3.2 vanilla and older On this setup I am getting rubbish frame rates after a short while of playing, dropping from about 45-55 to 15 in a couple of minutes. CPU use is 40-45 even when rendering the opening screen at 1920x1280, and gameRenderer is using about 90% CPU when playing. Rather than trying to eke out a few more FPS out of an obviously broken rendering pipeline, I really hope to find a solution to make the GPU render Minecraft.

• Problem with keyboard and trackpad on ubuntu 12.04

  - by Cdub

  Have a really strange issue with my keyboard and trackpad after installing ubuntu 12.04. It picked up both fine with the livecd and in the install, but for quite awhile now, I find when I power my laptop up (Toshiba Satellite L775D-S7132), when I hit the login screen much of the time I won't have any keyboard or touchpad. I can plug in a usb mouse and then at least restart or shut the laptop down and then keep trying until it picks it up correctly, but it's really a pain to have to do that all the time. Are there quite a few bugs related to keyboard and trackpad issues with the new version? I really want to get this issue resolved as it's a major nuisance. Otherwise, my hardware gets picked up fine. Video, audio, wlan, usb work perfectly and I don't ever have any issues with them. What's the best way to figure out the problem? Thanks in advance, C.

• Why is the superblock last mount time in the future?

  - by user69541

  Future time: Since installing Ubuntu 12.04, I regularly have to fun fsck and reset my clock because it shows a 'future time' : Err.Msg. "superblock last mount time is in the future by less than a day, probably due to hardware clock being incorrectly set." FIXED. According to what I have read, it looks like I'm in the right place to get an answer. Following are my feeble attempts to rectify this annoyance: mjh@mjh-desktop:~$ sudo service ntp start [sudo] password for mjh: ntp: unrecognized service mjh@mjh-desktop:~$ mjh@mjh-desktop:~$ sudo apt-get install update Reading package lists... Done Building dependency tree Reading state information... Done E: Unable to locate package update mjh@mjh-desktop:~$ sudo service ntp start ntp: unrecognized service mjh@mjh-desktop:~$ Suggestions?

• Web Based School/College ERP

  - by Ashok

  We are planning to build a Web Based School/College ERP. The main problem we face is Hardware support. Since it is Web Based, it is not possible to implement Biometrics. But most of our clients do ask for Biometrics. I hope we need to use a desktop application to do that. Can you please give some suggestions for this? Another thing is, here we don't have stable internet connection. We frequently face disconnection. This is another problem for Web Based CRM. In HTML5 there is a feature called Offline storage. Is it possible to use this feature for such dynamic ERP? For example, let's say we need to enter marks for the students. Net got disconnected. Is it possible to use HTML5 offline feature to save the marks offline and upload them when we got connection back?

• Getting older packages from ppa

  - by highsciguy

  Can I install an older version of a specific package from a ppa? Specifically, I want to get an older version of xserver-xorg-video-intel (and dependencies) from xorg-edgers ppa. The reason is that the older version seemed to work with my hardware. The present version seems to feature (I would like to found out if it is really the source) severe crashes as the present stable releases of this package do. I tried apt-get install pkg=version but didn't succeed. I am afraid that the packages in the cache are lost after apt-get clean I do not even know the precise version number of the previous version, assuming that it doesn't have to be exactly one less. The current version is xserver-xorg-video-intel-2.20.15 Alternatively: Is there a place, e.g. at launchpad, where I can manually download the previous version of the package?

• Why did the team at LMAX use Java and design the architecture to avoid GC at all cost?

  - by kadaj

  Why did the team at LMAX design the LMAX Disruptor in Java but all their design points to minimizing GC use? If one does not want to have GC run then why use a garbage collected language? Their optimizations, the level of hardware knowledge and the thought they put are just awesome but why Java? I'm not against Java or anything, but why a GC language? Why not use something like D or any other language without GC but allows efficient code? Is it that the team is most familiar with Java or does Java possess some unique advantage that I am not seeing? Say they develop it using D with manual memory management, what would be the difference? They would have to think low level (which they already are), but they can squeeze the best performance out of the system as it's native.
