I am well aware that there is "exactly" the same question already asked, but it seems the user that posted the question initially never took an interest in the question, and the answers all were for windows systems.
I want to take a picture with the webcam every N time units and store it to /tmp/somefolder/ for further use with other tools and only keep the last M images.
The main problem is taking the picture to start with, the rest i would have pretty much covered, would be glad for any suggestions.
OS: Ubuntu 10.04 x86_64
Webcam: MS LifeCam VX2000 and/or Logitech C210 (both working with cheese)

I have installed Ubuntu 12.10 leaving Win 7 licensed ver. But again as usual I need to fix so many issues.
This time fan is creating lots of noise. I was looking for the solution and found the below:
sudo tee /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq < \
/sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_min_freq
But I read that cpufreq is for cpu frequency. What to do now? I have already executed the command.
What is the solution for my problem of fan sound in Ubuntu 12.10. In win 7, this is not the problem.
I believe you are looking for
fancontrol

Anyone know some image viewers for Linux/Ubuntu
which have faster loading times than the
gimp and firefox which I can install with
apt-get, or which are already on the system.
Fed up of having to wait for these to load,
each time I need to view an image. I need
something fast and jiffy.
I'm also looking for sth I can run from the command line.
Try the "display" command line. apt-get install imagemagick

Conceptual question, just out of curiosity:
What is less taxing on the graphics processor: Anti-aliasing (2x? 4x? Higher?) on a typical desktop machine (around 120-150dpi) or to drive a hi-density (>300dpi) screen without anti-aliasing? This question could pertain to both desktop systems and embedded (smartphones). I'm interested to see the responses!
Neither usually, since font rendering and AA is done by the CPU (though you can use GPU features to blur). And then it depends on the font rasterizer and how good or bad it was implemented. It also depends on how AA was done, whether a matrix blur was applied, an FFT, or a simple render-bigger-and-bicubic-downsampling was used. Only runtime tests can show.

I need a small linux Text only version bootable installed on a partition of my hardrive, How can I customize a Linux version like redhat, debian, puppy etc. Please suggest some suitable distribution?
Depends on what you call small and what the purpuse of the installation is. I'd recommend [Debian stable][1] (Lenny) or [Ubuntu-server][2] for server-purposes. A really small distro is [Damn Small Linux][3]. If you just want to play around with a small-as-possible distro, you can try the time-consuming [Linux-from-Scratch][4].
Archlinux, definitely. But it's not programming related.

like what is X windows,Cygwin,file system
Well, first you have to choose which Linux distribution you wish to use/learn, then you just use that distro's documentation, which normally has allot info.
You can find here some linux beginner lessons: http://www.linux.org/lessons/beginner/toc.html
Finally the best way to learn, besides reading is "getting your hands dirty". Install a distro of your choice and mess with it :)
I think this is a great way to start
