Is is possible to do Open GL development and run programs on a computer with out a graphics card? (e.g. my netbook running Ubuntu)
Update This was many years ago, the link is not available anymore, and there are probably newer, better, builds now.
Yes, you can use MESA.
For your convenience, I've compiled it in both 32- and 64bit at:

Simply put them where your executable file is located.
Sure. Many software only implementations of OpenGL exist. Check out the Mesa project at http://www.mesa3d.org/ for one of the most popular. There are parts of the shading language not fully supported, and it tends to lag the standard a bit in general, but that is the case of all software API emulators. Its still very full featured and can be used in production code for many common uses.
You can use OpenGL on many integrated GPUs, mostly AMD chips like the Ryzen 3 3200G, which has a GPU that is the same as a GTX 1050 for around £100.

Could someone help me with the process of downloading opencl 1.2 on windows 10 with Nvidia geforce gtx 1050?
I downloaded the latest version of my nvidia graphics card, but when I look into its folders its shows an empty folder for openCL.
Should I be downloading any sdk's for nvidia? If yes where can I find it? I am able to find the nvidia openCL page here https://developer.nvidia.com/opencl but not sure which one to select
The OpenCL 1.2 runtime is already included in the graphics driver. There is no need to download any other software. You don't need any SDK.
For OpenCL development you will only need the OpenCL header files, see this post here.

So there was a popular article a few years back titled OpenGL 3 & DirectX 11: The War Is Over then there was this article titled OpenGL vs DirectX: The War Is Far From Over
I would like to know what is the stand today ? What is the future of OpenGL when compared to DirectX ? Is OpenGL catching up with latest specifications?
There is this recent article Return of the DirectX vs. OpenGL Debates but it doesn't say anything clearly about questions i asked.
What is the future of OpenGL when compared to DirectX
By the numbers OpenGL, especially its embedded variant clearly dominates the market. Practically every smartphone (except for Windows Phone) sold these days relies on OpenGL for its graphics output.
Also with Valve's strong push for the Linux market and their Steam Boxes, OpenGL gets another push. Other game makers and vendors are following into their steps, with many Triple-A game engines getting Linux ports these days.
Is OpenGL catching up with latest specifications?
These days OpenGL tends to be ahead of hardware development. The latest OpenGL specification is OpenGL-4.4, but the majority of GPUs and drivers found out there are still at OpenGL-4.3 (note that the major version number of OpenGL relates to the hardware class).

Last week my graphic card Nvidia (Cuda 2.0) stopped working and I had to plug in an old one which only supports Cuda 1.1. I have the NVidia Cuda 5.0 Toolkit installed. The project still compiles, but I get a runtime error. Therefore, my question is: do I have to reinstall Cuda again or change other settings in the cuda toolkit if I change the graphic card?
CUDA sdk is the same whatever your NVIDIA card but you should need to install the right driver. But you might change some settings in the code..

I was just wondering if it would be possible to install the CUDA toolkit without replacing my Display Driver. I don't mind the other changes that the installation would make to my system, but wish to keep my current NVIDIA display driver, rather than change to the one in the CUDA installation. Therefore, is this possible, or is the replacement display driver required to develop and run cuda programmes?
You need a display driver that is at least as recent as that included in the CUDA toolkit that you are installing. For example, Linux CUDA 5.5 requires a 319.37 or newer display driver, Linux CUDA 5.0 requires a 304.54 or newer display driver.
During the install of the toolkit, you will be prompted as to which components you want to install (driver, toolkit, samples). You can select no when prompted for the driver, if you wish to keep your driver. There are getting started guides for each of the supported platforms (windows, linux, mac).

I've recently started exploring the guts of VirtualBox's Guest Extensions on my Ubuntu Guest. Mostly from curiosity. Partly due to "OpenGL Warning: ... not found in mesa table" warnings. I noticed they are using Chromium OpenGL implementation. I have a two part question.
1.How do I get rid of those warnings? Are they indications of a larger problem? I'm noticing repaint issues which lead me down this path.
2.Am I missing something are is this a 12 year old project last touched 6 years ago!? Is it being actively developed some where else? Will it support OpenGL 3?
Online references would be appreciated as I'm having a hard time finding anything other than these below.

The chromium project is basically dead since 2008 or so. There is no support for GL3.x, and it is not planned. Actually, implementing the main purpose of chromium (application-transparent distributed rendering by manipulating the GL command stream) is incredibly hard to outright impossible with the programmable pipeline and modern GL features.
I'm not really familiar with virtualbox, but I am aware that they just used parts of the chromium project to implement a hw-accelerated guest GL simply by forwarding the GL command stream to the host. Such a task is much easier to adapt to modern GL, as no real stream manipulation is to be done. But I'm not aware of how far they have come on that path. So consider this only half of an answer to your question.
