• Missing driver ASUS PCE-N53 11n N600 PCI-E Adapter

  - by oyse

  I have problems with getting an Asus PCE-N53 11n N600 PCI-E Adapter card to work on my desktop computer. As far as I can tell no drivers are installed for the card. I know I can manually download the drivers directly from Asus, but I would rather not go that route. If there are anyone that knows about any packages or other things I can do to make this work would be much appreciated. Some systems details: $ lsb_release -a No LSB modules are available.

• LOD in modern games

  - by Firas Assaad

  I'm currently working on my master's thesis about LOD and mesh simplification, and I've been reading many academic papers and articles about the subject. However, I can't find enough information about how LOD is being used in modern games. I know many games use some sort of dynamic LOD for terrain, but what about elsewhere? Level of Detail for 3D Graphics for example points out that discrete LOD (where artists prepare several models in advance) is widely used because of the performance overhead of continuous LOD. That book was published in 2002 however, and I'm wondering if things are different now. There has been some research in performing dynamic LOD using the geometry shader (this paper for example, with its implementation in ShaderX6), would that be used in a modern game? To summarize, my question is about the state of LOD in modern video games, what algorithms are used and why? In particular, is view dependent continuous simplification used or does the runtime overhead make using discrete models with proper blending and impostors a more attractive solution? If discrete models are used, is an algorithm used (e.g. vertex clustering) to generate them offline, do artists manually create the models, or perhaps a combination of both methods is used?

• Does a system exist to facilitate virtual meetings and file sharing?

  - by CSharp Mania

  I'm looking for a system that is similar to an online classroom setup but allows for virtual meeting rooms with video/audio conferencing, and of course file sharing. I'm preferring an open source solution that I can edit/tweak myself as needed, and is of course free. Ultimately, I guess what I'm looking for is something that we could possibly tweak to give our own "branded" look and feel, if possible, along with full integration within our own servers. Thus the reason I brought up open source solutions. Do you masters of the web know of such a system available? If so, do you have a preferred one that you would suggest? OR, can such a system be developed by slapping together a couple of open source projects to derive at what is desired? Thanks for sharing your expertise. (FYI - I am a developer that is comfortable with PHP and C#. I'm not experienced with Ruby or Python, but a system using them or something else is acceptable. We can figure it out I'm sure.)

• Most effective way to do daily standup meeting when a few people are remote

  - by Burhan Ali

  I am a software developer in a small team of seven. We are not an Agile (with a big 'A') team but are experimenting with some aspects of agile. One of these is the daily "standup" meeting. The difficulty here is that for two days of the week we have at least one person working from home so the full team isn't available in the same room. What is the best way to carry out a daily standup in this situation? Some facts that may be relevant: We all work in a single open plan room. We use Skype in our company. We don't have any video conferencing capability. We all work the same hours so there are no timezone complexities involved. The development manager is one of the people who works from home one day a week. Things we have tried: Conference call using Skype: This is tricky for those in the office because you can hear people speak in the room and then a split second later through the headset. This can e very distracting. Conference phone: Awful experience. Hard to get them to work and poor quality audio. Text-based updates using Skype. This is not as engaging and is no different than just firing off a status email in the morning. I have seen other questions about remote collaboration but they are mainly about completely remote teams and/or teams that span multiple time zones. We are not affected by either of these problems. What can we do to make our standup meetings better in these circumstances?

• CyanogenMod Updates; Rolls out Android 2.3 to the Less Fortunate

  - by ETC

  If you’re one of the less fortunate (namely those forgotten by their carrier when it comes to phone OS upgrade time) you’ve got a friend in Cyanogen. They’ve rolled out a new Release Candidate update that includes Android 2.3 and a host of performance tweaks. First thing to note is that this is an RC and if you upgrade from CyanogenMod 6 to CyanogenMod 7 RC you’ll be trading a little bit of stability and a few features that haven’t made the jump from 6 to 7 in return for the newest features of Android 2.3. If you’re not comfortable with that wait for CyanogenMod 7 to update to a final release. For the intrepid, hit up the link below to read more and grab a copy. CyanogenMod-7 Release Candidates!

• Collision planes confusion

  - by Jeffrey

  I'm following this tutorial by thecplusplusguy and in the linked video he explain that for example for the world basement and walls we need to create the actual rendered (shown to the player) walls and then duplicate them, place them in the same coordinates as the rendered walls and call them collision (by defining their material to collision). Then it defines in the Object loader function that those objects with material == collision are collision planes and should not be rendered but just used to check collision. Now I'm pretty confused. Why would we add this kind of complexity to a problem that can easily be solved by a simple loadObject(string plane_object, bool check_collision);: Creating only the walls object (by loading .obj file in plane_object) Define them also as collision planes whenever the check_collision is set to true In this case we have lowered the complexity of his method and make it more flexible and faster to develop (faster because we don't always have to make a copy for each plane and flexible because we don't hardcode the Object loader). The only case in which this method could not work is when we need hidden collision planes, and for that we could modify the loadObject() function like this: loadObject(string plane_object, bool check_collision = true, bool hide_object = false); Creating only the walls object (by loading .obj file in plane_object) Define them also as collision planes whenever the check_collision is set to true And add the ability to actually show the object or hide it based on hide_object. The final question is: am I right? What would the possible problem encountered with my solution versus his?

• CUDA & MSI GT60 with Optimus enabled GTX670M?

  - by user1076693

  I have a MSI GT60 Laptop with an Optimus enabled GTX 670M GPU, and I have been trying to get CUDA going in Ubuntu 12.04 environment. I realize that Optimus is not supported in Linux, but I have read the following post suggesting that CUDA works for hybrid GPUs. How can I get nVidia CUDA or OpenCL working on a laptop with nVidia discrete card/Intel Integrated Graphics? I installed the NVIDIA driver via sudo add-apt-repository ppa:ubuntu-x-swat/x-updates sudo apt-get update sudo apt-get install nvidia-current The resulting driver version is 302.17, and supposedly GTX 670M is supported since 295.59. I also downloaded CUDA 4.2 from the NVIDIA site, and compiled it against nvidia-current libraries. Unfortunately, when I run deviceQuery in the CUDA SDK, I get the following output cudaGetDeviceCount returned 38 -> no CUDA-capable device is detected Checking /proc/driver/nvidia/gpus/0/information gives the following Model: GeForce GTX 670M IRQ: 16 GPU UUID: GPU-????????-????-????-????-???????????? Video BIOS: ??.??.??.??.?? Bus Type: PCI-E DMA Size: 32 bits DMA Mask: 0xffffffffff Bus Location: 0000:01.00.0 Here is the output of "lspci | grep VGA" 00:02.0 VGA compatible controller: Intel Corporation Ivy Bridge Graphics Controller (rev 09) 01:00.0 VGA compatible controller: NVIDIA Corporation Device 1213 (rev ff) So... what am I doing wrong?

• I am having trouble booting 12.04 keyboard and little man in circle appears and then nothing

  - by Rich J.

  I have a new system (ASUS 990FX mother board, 2 western dig drives, 32 gb memory, an ASUS nvidia video card (GeForce GTX560), and an ASUS DVD Burner (24B1ST)) I am struggling to get the 12.04 cd to work. I have been able to see the little man inside a circle and a graphic of a keyboard? with an == sign between them. Is this is a clue? What does it mean? After that the mauve screen with keyboard and little man in circle goes away. I get a dark background and underline cursor... even hear some work being done reading the rom.... but nothing appears on the screen. I haven't even got to the point where the graphic card is displaying improperly... it is just not displaying anything. If any kind soul has an idea about how to proceed, I am all ears. BTW, I have posted the issue to ASUS... waiting for reply.

• Abstract Factory Method and Polymorphism

  - by Scotty C.

  Being a PHP programmer for the last couple of years, I'm just starting to get into advanced programming styles and using polymorphic patterns. I was watching a video on polymorphism the other day, and the guy giving the lecture said that if at all possible, you should get rid of if statements in your code, and that a switch is almost always a sign that polymorphism is needed. At this point I was quite inspired and immediately went off to try out these new concepts, so I decided to make a small caching module using a factory method. Of course the very first thing I have to do is create a switch to decide what file encoding to choose. DANG! class Main { public static function methodA($parameter='') { switch ($parameter) { case 'a': $object = new \name\space\object1(); break; case 'b': $object = new \name\space\object2(); break; case 'c': $object = new \name\space\object3(); break; default: $object = new \name\space\object1(); } return (sekretInterface $object); } } At this point I'm not really sure what to do. As far as I can tell, I either have to use a different pattern and have separate methods for each object instance, or accept that a switch is necessary to "switch" between them. What do you guys think?

• Submitting software to a competition, it becomes their property?

  - by myrkos

  So I'm about to submit a game to a competition, but as I looked through the rules a chunk grabbed my attention: All Entries become the sole and exclusive property of Sponsor and will not be acknowledged or returned. Sponsor shall own all right, title and interest in and to each Entry, including without limitation all results and proceeds thereof and all elements or constituent parts of Entry (including without limitation the Mobile App, the Design Documents, the Video Trailer, the Playable and all illustrations, logos, mechanicals, renderings, characters, graphics, designs, layouts or other material therein) and all copyrights and renewals and extensions of copyrights therein and thereto. Without limitation of the foregoing, each Eligible Entrant shall and hereby does absolutely and irrevocably assign and transfer all of his or her right, title and interest in his or her Entry to Sponsor, and Sponsor shall have the right and may authorize others to use, copy, sublicense, transmit, modify, manipulate, publish, delete, reproduce, perform, distribute, display and otherwise exploit the Entry (and to create and exploit derivative works thereof) in any manner, including without limitation to embody the Entry, in whole or in part, in apps and other works of any kind or nature created, developed, published or distributed by Sponsor and to and register as a trademark in any country in Sponsor’s name any component of the Entry, without such Eligible Entrant reserving any rights or claims with respect thereto. Sponsor shall have the exclusive right, in perpetuity, throughout the Territory to change, adapt, modify, use, combine with other material and otherwise exploit the Entry in all media now known or hereafter devised and in any manner, in its sole and absolute discretion, without the need for any payment or credit to Entrant. So the game will become the sponsor's property; however, they don't ask for source code. So will I still own the rights to the source code, whatever that means? And if it doesn't win said competition, will I be able to publish it myself without their trademarks? I am very new to software legality stuff, so I would appreciate any clarification. Since there's a possibility I won't even own the source, is it possible to make the game core engine open source software with a not-very-restrictive license and include that in the project, so I at least still own the game engine? Or does it not work that way?

• Added resolution not working after upgrading to 12.04

  - by David

  After upgrading, my screen resolution (added by xrandr comands on the start) did not work like before. Messages appear showing some errors (that i have never had in 11.10). "No se pudo aplicar la configuración almacenada para los monitores"/"Can't apply the stored configuration for the monitors." This script didn't work either. xrandr --newmode "1280x1024_60.00" 109.00 1280 1368 1496 1712 1024 1027 1034 1063 -hsync +vsync xrandr --addmode VGA1 1280x1024_60.00 xrandr --output VGA1 --mode 1280x1024_60.00 I also tryed deleting monitors.xml but, nothing. This only erase the window message. It's been sayd that ##It's a normal buggy and well know problem for Pc's with Intel integrated video cards.## The new version of gnome-settings-daemon stores its configuration information in dconf rather than gconf. I tryed something, but the problem persist. This is what i did. Install the dconf-tools package, and then run dconf-editor. In the tree on the left, navigate org - gnome - settings-daemon - plugins - xrandr. Uncheck the active checkbox. restart your XServer (Ctrl+Alt+Backspace) (It didn't worked out for me, but it may be helpful to someone)

• How can I get nvidia-96 installed?

  - by Bob

  I'm at my wits end here. This is my last effort before I go back to Windows. I need to get nvidia-96 proprietary driver installed. Synaptic won't install it because it says it has dependencies. I installed every single dependency it listed except for "xorg-video-abi-10" which does not show up as an item that can be installed. I have no idea what to do. Using 11.10 with a NVIDIA Geforce 3 GPU. Anyone know how to get this dang driver installed? @fossfreedom: the opensource driver is extremely slow. So slow that the OS is unusable—words appear seconds after I type them—programs take forever to perform actions. Also it is causing my monitor to turn on and off for no reason. @yossile: synaptic shows that I have xserver-xorg-core installed. And xserver-xorg-core-udeb does not show up as something that can be installed. @papseddy: when I try to install the downloaded nvidia driver it says it won't work until I disable Nouveau kernel driver. I have tried everything to get this dang Nouveau kernel driver disabled. Nothing has been successful.

• Upgrade to 0.25, files served to uPNP devices cannot play

  - by David Buttrick

  I have a Sony BDP-S390 bluray & network player. I upgraded my Myth server to 0.25. When I browse to the Myth server, and try to play a recording, I get an error message about the file not being payable in the player. Interestingly, the files that i have recorded, and the videos that I have loaded into my Video volume group are .mpg or .mp4. The player shows the filetype that it thinks the file is in it's list, and it claims that these files are AVI files, however none of them are. They are all .mp4 or .mpg files. Thinking that that was just an optical illusion, I went ahead and tried to play a file, but I get an error about the file not being playable. First of all, is there something that I need to do to make the uPNP server know about different filetypes? Is it reporting AVI because it hasn't been told about MPG or MP4? Second, I'd like to help out some more here and collect some logging about the uPNP server in the myth server. I cant seem to find information on how to turn on logging, and there is no mythbackend settings file int /etc/default. Thanks very much.

• Frustrated with MythTV 0.26

  - by Mike

  I've been using MythTV for a while now. Until a hardware crash I had a 0.25 box running without problems. Had to get new hardware and am now in the process of setting up 0.26. Every time I pick a menu option, it hangs for 1 minute. Every time I try to start the backend, same thing. I pick a new theme in the frontend, but it never gets used. I try to test audio, but all I get is static (from the proper channels though). I've setup the storage groups in the backend and put a video in /storage/videos but the front end won't see it when I scan for changes. I make changes in the front end configuration and they don't get saved (or get lost randomly 2-3 reloads later). Obviously there is something I am doing catastrophically wrong, but I have no idea what. Are the storage groups not working yet? Maybe I need to delete all the storage group entries and just use the front end override to set the path? I'm currently using lvm across 3 hard disks, and this has worked well for me in the past. I'd like to use storage groups, but frankly I don't see them working yet at all - especially not for videos (which is what we watch 99% of the time). Anyone have any suggestions for me to try before I just call 0.26 bad names and wipe the system?

• NVIDIA X Server TwinView isses with 2 GeForce 8600GT cards

  - by Big Daddy

  Full disclosure, I am relatively new to Linux and loving the learning curve but I am undoubtedly capable of ignorant mistakes I have a rig I am building for my home office desktop. The basics: Gigabyte MB AMD 64bt processor Ubuntu 12.04 64bit two Nvidia GeForce 8600GT video cards using a SLI bridge two 22" DVI input HP monitors So here is my issue (it is driving me nuts) with X Server. If I plug both monitors into GPU 0 X Server auto configures TwinView and all is grand, works like a charm, though both are running off of GPU 0. If I plug one monitor into GPU 0 and one monitor into GPU 1, X Server enables the monitor on GPU 0, sees but keeps the monitor on GPU 1 disabled. My presumption (we all know the saying about presumptions) is that all I would have to do is select the disabled monitor on GPU 1 and drop down the Configure pull down and select TwinView...problem is when the monitors are plugged in this way, the TwinView option is greyed out and can not be selected. What am I not understanding here? Is there some sort of configuration I need to do elsewhere for Ubuntu to utilize both GPU's? Any help will be most appreciated, thanks in advance.

• Disappearring instances of VertexPositionColor using MonoGame

  - by Rosko

  I am a complete beginner in graphics developing with XNA/Monogame. Started my own project using Monogame 3.0 for WinRT. I have this unexplainable issue that some of the vertices disappear while doing some updates on them. Basically, it is a game with balls who collide with the walls and with each other and in certain conditions they explode. When they explode they disappear. Here is a video demonstrating the issue. I used wireframes so that it is easier to see how vertices are missing. The perfect exploding balls are the ones which are result by user input with mouse clicking. Thanks for the help. The situations is: I draw user primitives with triangle strips using like this graphicsDevice.DrawUserPrimitives<VertexPositionColor>(PrimitiveType.TriangleStrip, circleVertices, 0, primitiveCount); All of the primitives are in the z-plane (z = 0), I thought that it is the culling in action. I tried setting the culling mode to none but it did not help. Here is the code responsible for the explosion private void Explode(GameTime gameTime, ref List<Circle> circles) { if (this.isExploding) { for (int i = 0; i < this.circleVertices.Length; i++) { if (this.circleVertices[i] != this.circleCenter) { if (Vector3.Distance(this.circleVertices[i].Position, this.circleCenter.Position) < this.explosionRadius * precisionCoefficient) { var explosionVector = this.circleVertices[i].Position - this.circleCenter.Position; explosionVector.Normalize(); explosionVector *= explosionSpeed; circleVertices[i].Position += explosionVector * (float)gameTime.ElapsedGameTime.TotalSeconds; } else { circles.Remove(this); } } } } } I'd be really greatful if anyone has suggestions about how to fix this issue.

• What kind of language will replace C++ as C++ replaced C ? [closed]

  - by jokoon

  I think I'm not totally wrong when thinking that C++0x (or C++1x) is still C++, just better, with functionnalities coming from boost. I can't stop thinking that computer sciences, even with all that has been made so far, have to evolve again. I don't really like D since it just try to be some sort of "what C++ should have been", and Go seems to be too sophisticated when I dig a little into it, especially after watching some presentation video like this one http://www.youtube.com/watch?v=rKnDgT73v8s The first thing that come into my mind is a new kind of syntax to directly handle specific datatypes and containers such as map, vectors, queues... What kind of things are researchers thinking about ? What are the real features that could make C++ better or a new C-like language could invent ? Does Go features such things ? Would there be a new kind of syntax that would "unbloat" C++ while keeping its advantages ? Could C++ have some of the interesting stuff of languages such as C# and ObjC ? EDIT: Please consider that I'm talking about a system language, not a VM/CLI/bytecode thing.
