  • Ubuntu 13.04 on Lenovo G580 > built-in (web)cam not recognized

    - by user159295
    I've installed Ubuntu 13.04 on a Lenovo G580. Now I noticed that the built-in (web)cam is not being recognized. Does anybody know how to fix this and get the webcam running? Any help is appreciated! Thanks I've downloaded/installed the suggested program and the webcam is working within that program. However, when running Camera Test from the System Testing here's what happens: when clicking on "Test", there's NO image showing up a few seconds after clicking on "Test", an error message is popping up saying "Sorry, Ubuntu 13.04 has experienced an internal error" When going to Skype, video is enable and under "select webcam" there's "Lenovo EasyCamera (/dev/video0) as only option selected. But, Skype doesn't recognize the camera as there's no pictures. Any ideas on how to get this straightened out?

  • Why do people use programming books?

    - by Alex Hope O'Connor
    I find that when someone asks what is the best way to learn how to program, people usually provide them with references to a bunch texts written by various authors. However I don't believe many people at all learn to program from books? I find that they are usually faced with a challenge and then use programming as tool to overcome it. For example I 'got into' programming because I wanted to start a server for a game I was playing, so I googled and read through the support for that particular server and now I am a employed software engineer, using only the skills I developed (and then further developed) by coding C# scripts for a not very popular server package. So my question is, do people generally find it easier to learn from these books? I know I have looked at a few of them and found them far too 'dry' to encourage me to finish it.

  • Because of over incumbent patents, is it possible to safely develop any software without the risk of legal action?

    - by Chris Barry
    Take this System and method for restricting user access rights on the internet based on rating information stored in a relational database There are hundreds of thousands of them out there. So basically you can't program anything really without breaching one of thousands of software patents. If your program succeeds you will be sued by someone! Does this happen all the time and people get silenced? Do trendy startups get hit by things like this? Surely all major web properties would have been hit by the example above by AT&T?

  • nVidia GeForce Go 7600? can it ever run unity?

    - by Khaled Musleh
    my laptop Toshiba Qosmio G30 has nVidia GeForce Go 7600 card and it suppose to support 3D . i run unity 2d now . I run 12.04 and the graphic driver is--VESA: G73 Board - toshg73m-- by UBUNTU. when i run /usr/lib/nux/unity_support_test -p then i get this list Not software rendered: no Not blacklisted: yes GLX fbconfig: yes GLX texture from pixmap: yes GL npot or rect textures: yes GL vertex program: yes GL fragment program: yes GL vertex buffer object: yes GL framebuffer object: yes GL version is 1.4+: yes Unity 3D supported: no the card is not blacklisted but a similar one with GT is! Do you think that there is a chance the laptop can run the unity 3d? and may be i could change the resolution of the screen to a higher one too! I tried all the nvidia drivers provided but none works (except 96 in ubuntu 12.04 ). i get a black screen or terminal screen. best wishes to all

  • Ogre3D : seeking advices about game files management

    - by Tibor
    I'm working on a new game, and its related level editor, based on Ogre3D. I was thinking about how i could manage the game files, knowing that Ogre use .mesh files for models, .material for materials/texture information etc... . At first i thought about a common .zip folder decompressed at runtime (the same way Torchlight and Ogre samples do). But this way the game assets become a monolithic archive, loading takes time, and could be difficult to eventually patch them. So, let's say i have a game object named "Cube" i want to load in my program. Going for modularity, what if i create a compressed file (using zlib compression routines) named Cube.extname, containing its sub-files Cube.mesh, Cube.material and so on ? Are there any alternatives or should i stick with compressed objects? PS: Just to clear things, the answer is unrelated to my program code, at the moment i'm using "resources.cfg" pointing to the OgreSDK media directory.

  • What are some concepts people should understand before programming "big" projects?

    - by Abafei
    A person new to programming may be able to make a good small program. However, when starting to work on anything bigger than a small (think 1 C source file or Python module) program, there are some general concepts which become much more important when working on "big" (think many Python modules or C files) programs; one example is modularity, another is having a set aim. Some of these may be obvious to people who went to school to learn programming; however, people like me who did not go to programming classes sometimes have to learn these things from experience, possibly creating failed projects in the meantime. ================================================== Please explain what the concept is, and why the concept becomes more important for big programs than by small programs. Please give only 1 concept per answer.

  • Problem with dash - there are no programs on the list

    - by sky
    As I said. There are no programs on the dash list (seacher on appmenu). Yesterday I logged into my account and I tried to find some program but there wasn't any! Additionaly, I tried to view installed programs and manually find program which I looked for, but nothing was displayed :( And today, when I want to turn on Ubuntu Software Center, it just don't turn on .< I'm using Ubuntu 11.10 (64bit). I installed "fresh" O.S. few days ago. Ubuntu is updated and has many Gigabytes of disk memory available. Please help me and my unfortunate O.S. Thank you for all answers.

  • MathType and LibreOffice Math comparison

    - by Agmenor
    In my office my team and I are going to type texts in the future which will include mathematical signs. Two programs are being proposed: LibreOffice Writer + Math or Microsoft Office + MathType. I would like to advocate for the first solution, but I need to know what technical advantages and disadvantages each program has. Compatibility with Ubuntu is an evident and important characteristic for LibreOffice, but could you give some other aspects? As a side question, do you advice any other program, even if not WYSIWYG and thus not my preference in this case?

  • Is it a waste of time to free resources before I exit a process?

    - by Martin
    Let's consider a fictional program that builds a linked list in the heap, and at the end of the program there is a loop that frees all the nodes, and then exits. For this case let's say the linked list is just 500K of memory, and no special space managing is required. Is that a wast of time, because the OS will do that anyway? Will there be a different behavior later? Is that different according to the OS version? I'm mainly interested in UNIX based systems, but any information will be appreciated. I had today my first lesson in OS course and I'm wondering about that now.

  • SharePoint and Visual Studio - Replaceable parameters

    - by Sahil Malik
    SharePoint 2010 Training: more information What is a replaceable parameter? Sometimes you may see something like $SharePoint.Project.AssemblyFullName$ in your code. Visual studio is doing some magic to replace it during compile/build time with the full assembly signature. The following apply to these tokens or replaceable parameters - Tokens can be specified anywhere in a line. Tokens cannot span multiple lines. The same token may be specified multiple times on the same line and in the same file. Different tokens may be specified on the same line. Tokens that do not follow these rules are ignored without providing a warning or error. The replacement of tokens by string values is done immediately after manifest transformation, thus allowing manifest templates edited by a user to use tokens. Visual studio supports the following replaceable parameters -   Name Read full article ....

  • I'm a C Programmer, but I can't find a comfortable environment to work in

    - by Jesse Brands
    Hello everyone, Last time I asked a question, I was having issues dealing with Java which I had to do for a course work. I generally use C for my development work - especially personal projects - and I've grown up in what is pretty much a Linux/UNIX world. In this world, it was easy to use C, you had your C compiler (GCC is excellent in that regard) and a wealth of tools such as the command line and vi/emacs/whatever-you-got. However, that was all that I really liked about Linux/UNIX. It really fitted well with the C language; nowadays, I'm somewhat forced into Windows/Mac OS X for most of my work. C seems poorly supported on a mac for starters, there's no GUI API to use and pretty much you get forced into Obj-C. This is not a problem, I like Objective-C, but it's another language I have to learn. Now coming to Windows. Why does everything about Windows Development try to scare me away? It's basically come down to: USE C# AND .NET OR DIE. I don't like C#, I like C, they are fundamentally different. Yet when I make a Windows Forms application in MSVC++ (I know that's not C), I get a main function riddled with weird things I've never heard of before, along with a poor, barely-compliant C/C++ compiler. What am I to do when I just want to program in C, make applications that look and feel like native Windows applications (I am a sucker for aesthetics, and I'm not looking to make something cross-platform. I just want it to work on Windows, and look as native as possible.). C++ is a fine alternative, but it really looks like the only way to make a decent, native feeling Windows application, is to use C#. Am I missing something here? I'd rather not use CYGWIN. Like I said, I want people to install the program, and it should just work out of the box on Windows 7. Program in question involves a Media Player, if anyone is curious what I'm targetting at. Anyone who had the same experiences who can help me out? How can I code something in ANSI C and still have a native feel?

  • Horible lag on Xubuntu media center setup

    - by William
    I am setting up a media center running Xubuntu 11.10 as a media center. It is using the XFCE desktop enviroment. I have the NVIDIA drivers installed from the Additional Drivers program, and uninstalled all but the esennitial software. The computer is a Dell Dimension 3000. You can view detailed technical specifications here. The graphics card installed is a Geforce 8400 GS. I have installed all updates through Update Manager. What can I do to fix the horrible lag? It makes watching TV impossible.I have uploaded two videos of the lag, here and here. The second one does not have sound because the sound stops playing on some channels that lag a lot. The TV card is a Hauppage 950q USB, and the TV recording program is Kaffiene. Please help me with this, I am trying to do this to show how great Ubuntu is to the rest of the family.

  • How to check last changes in filesystem or directory with bash?

    - by Robert Vila
    After the system unmounted the root partition I detected that some files are missing in the filesystem. wifi and the gwibber icons disappeared from the indicator applet I want to check if there are other files missing using the ls program and the locate program, which woks on indexes of a previous state of the filesystem. Thus, locate '/usr/share/icons/*' | xargs ls -d 2>&1 >/dev/null serves for that purpose, and I can count the nonexistent files like this: locate '/usr/share/icons/*' | xargs ls -d 2>&1 >/dev/null | wc -l except for the case where filenames have blank spaces in them; and, not very surprisingly, that is the case with Ubuntu (OMG!! It is no longer "forbidden" like in good old times). If I use: locate '/usr/share/icons/*' | xargs -Iñ ls -d 'ñ' 2>&1 >/dev/null it is not working because there is some kind of interference in the syntax between the redirections of the standard outputs and the use of the parameter -I. Can anyone please help me with this syntax or giving another idea?

  • Gnome shell crashing in 11.10 with 'purple haze' effect

    - by Andy
    I've just got Gnome with 11.10 up and running with my netbook and liked it so much I thought I'd get my parents old machine sorted with Ubuntu too. Unity works fine but when I try to switch to Gnome shell, I get problems. On login, the wallpaper appears as normal but then the colour bleeds out from the centre, leaving traces of it around the edge in a purple haze (yes, I do like Jimi Hendrix but I'm not making this up). When I go to applications, typing then pressing enter in the search field dumps me out so there's nothing but File / Edit / View etc in top left; starting a program seems to work but then there's only a white screen and no program window. Gnome classic works fine, from the limited use I've given it. I'm using an Asus desktop with ABIT motherboard, 2.6ghz with 1gb RAM; I've checked drivers and it says I'm up to date, Nvidia graphics. Anyone any ideas?

  • Deploying a very simple application

    - by vanna
    I have a very simple working console application written in C++ linked with a light static library. It is just for testing purposes. Now that the coding part is done, I would like to know the process of actually deploying the program. I wrote a very basic CMakeLists.txt that create makefiles or VS projects to build the sources. I also have a program that calls the static library in order to make some google tests. To me, the distribution of this application goes like this : to developpers : the src directory with the CMakeLists.txt file (multi-platform distribution) with a README.txt and an INSTALL.txt to users : the executable and a README.txt git repo : everything mentionned above plus the sources for testing and the gtest external lib A this point : considering the complexity of my application, am I doing it right ? Is there any reference that would formalize this deployment process so I can get better and go further ? Say I would like to add dynamic libraries that can be updated, external libraries like boost : how should I package this to deploy it in a professionnal way ?

  • Ubuntu: how to change the right click "open with" application order?

    - by ramgorur
    I am using Ubuntu 10.10 Maverick, when I try to open a plain text file using a program x, I do right click to access the "open with" application list. Suppose my current "open with" list is like below -- application z application y application x But I want it to be like -- application x application y application z i.e. I want to change the order of the list. I know that I can fix a "default program" for a particular file, but that's not what I am looking for. My question is which file defines this "open with" preferences? and if there is any way to tweak it. Any idea?
