I was just wanting to go ahead and make an OS. Because working on projects makes one's knowledge quite good enough. I know I will have to study OS inside-out before actually trying to implement one on my own. I also know I wouldn't be able to implement something right from square one. So I searched the internet for something to work upon. The most common option that I found was to work upon existing Linux distro and contribute to it.
But I found some more interesting options. Would like your suggestions on what to choose for and work upon.

PintOS: http://www.scs.stanford.edu/10wi-cs140/pintos/pintos_1.html#SEC1
Cosmos: http://www.gocosmos.org/index.en.aspx
I would get around 6 months time to work upon it. But before I start off with it, I want to do my research work properly and finalize what and how to work.
Drop in your suggestions on what should I use to work on. :)

The official Chrome extensions documentation seems terribly out of date. For example, this page references chrome.tabs.getSelected() method, which has been deprecated long ago (one should use chrome.tabs.query() now).
The samples page is also outdated. Almost none of the samples I checked worked.
So, naturally, I wonder, when can one get relevant documentation on Google Chrome extensions?
The API documentation should be current. If you want something more tutorial-like the other pages are useful but you should cross-check with the API reference since you are correct that the APIs still change relatively often.
http://tutorialzine.com/2010/06/making-first-chrome-extension/ might be a good place to start.

I want to write a simple applet to put in a tray. Let's say it will be for gnome taskbar or tint2. My applet should show system temperature or any other simple information by probing at a fixed amount of time /proc or maybe providing this info by clicking on the applet itself, I still have not decided.
My knowledge is limited, since I don't know where to start. What I need is some little info, on the difficulty of the matter, provided I'm fairly ok with bash, but that's it.
Where do I start and what should I read first? There should be gui, then is it gtk, qt or something else? Maybe somebody got a good link or just your opinion will be a good start for me.
Assuming you mean GNOME 2, you could start reading the document Gnome applets with Python. You will get the idea behind applets and how to do it with Python. For tin2 the API might be totally different.

Can anyone tell me links for reading about mainframe internals like what happens in mainframe intrenally when I login or create a dataset or submit a job. I googled but couldnt find
Thanks in advance
The Principles of Operation will give you as low-level a look at mainframe internals as you're likely to get.
You mention wanting to know what happens internally "when I login or create a dataset or submit a job." You might want to ask yourself, "login to what?" exactly. TSO? CICS? IMS?
For creating datasets you might start with DFSMS.
For submitting jobs you might want to start with JES2 or JES3, depending on which one you're using.
None of what you're asking is a small topic.
A mainframe is fundamentally just like any other computer - it is just a matter of scale that differentiates a mainframe from a desktop. Fundamentally, what happens when you log in to a Windows desktop is very similar to what happens when you log in to a mainframe. The details are very different but fundamentally you are doing the same thing.
The links cschneid provided in his answer will give you a lot of the finer detail, but conceptually, what goes on inside a mainframe is similar to what goes on in any computer these days.

I am making a game in which you move the character with the arrow keys, and I want to do something when it collides with a certain step. (See picture below). I want the top value of my character to increase every time it touches the steps, and the second flight of stairs, I want it to descend. I have tried and tried to no avail. Any help?
Doing a Bing search on Collosion detection with VB6, I found a few articles out there.
Try looking at:
http://www.vb6.us/tutorials/rectangular-and-circular-collision-detection-vb6
But as #Matt Ball is trying to say, is in order to help you we need to see what code you have tried. Otherwise anything we come up with is just a guess of what your problem is.

Please I need help on how to create a nice looking UI. Now I suppose that people looking at this question have an android, if so go to the market. Download a app called, "Quick Settings". It has a great UI and I want to learn how to make mine look as good as that one, if you have any kind of help, it would be appreciated. Thanks.
A quick Google search brings up lots of good tips, tricks and tools for designing Android UIs. Here are a few:
