Question to be solved
 

I have list of question and I am listing it

1.First do there is any open source for keiluvision. Keiluvision is a paid software for doing programming of microcontroller.
2.Is there are open source available for doing programming of microcontroler.
3.And whether they are as good as these paid software.
Would anybody can suggest me any open source software for converting mp4 videos to 3gp videos on mobile. Software must be open source and would they compete with Softwares like total video converter, Any converter.
4. What is the best way to learn linux.
5. I want that I should do everywork on linux through terminal. Wolud this possible and then how to learn more about working on terminal.

4. Install and use it :)

5. You can do most stuff at cmd line (cli), but eg surfing the web or office type stuff is best done with a GUI.
However, you can do both (as I do :) ).
Just install the desktop GUI for the tasks that require it, then open up a terminal session (or several) for the cli tasks.

This appears to be a cross-post (duplicate or triplicate), but this version has the most helpful answer, so far, so it appears that this version is the one that might have most future.

Not that I know of. On the other hand, I haven't looked at any of Keil's products for in excess of 5 years and things might have changed. Perhaps asking Keil or looking at their website is the most direct thing. (Note that there are free versions of Keil products, but that isn't apparently what interests you.)

Yes.

Yes and no. It is hard to compare unspecified products with unspecified products, particularly when the question implicitly covers such a wide field, and against an undefined quality criterion, but there are varitions in both what you might want and how you might evaluate.

Does 'good' to you primarily mean quality of emitted code? And if so, do you have a variety of quality criteria for that code? Well, in that case, maybe and up to a point.

Does 'good' to you mean shallowness of learning curve, hand-holding and that sort of thing (probably including, but not limited to, prettiness of user interface)? In that case it is harder to make the case. As it would be if quality and thoroughness of documentation was all important.

Questions 4 & 5 have already been answered, but really the only way of doing it is doing it. I'm not clear why this should be an objective at this stage, and you'll certainly find that you have just made the learning curve more noticeable, but if that is what you have decided to do, it is what you have decided to do.
