One way is to use recursive function calls. Just search online for "factorial recursion" for details.

[Ilugc] Making a Career in FOSS [New Business]
Hello All, I am a final year BE student. While most of my mates are sincerely searching for a spot in the corporates, me and two of my friends cherish a dream of creating a business for ourselves. We got something like a few website development offers and that has motivated us further. But we are not really going to stick to web development as such and want to get into customized application development and software deployment. I recently saw a message in the "NCR Python Users Group India" discussing Data Mining tool for collecting data from Excel Documents and displaying them on web pages. I think these are some untapped areas of software deployment, at least here in India. So, now the questions in my mind are: 1. Can we really survive as a company creating application specific or customized software for situations like the one I have mentioned above? 2. Is there really market for such software and services in India? Kindly keep in mind FOSS. 3. If there is a possibility to survive. Are we going to be judged by the work we do or by the industry experience we have or supposed to have? (Remember I am still at college) 4. At last, how much are we going to be paid for these kind of jobs? Keeping in mind that depends on the quality of work we do and our ability to negotiate, I would like to know the scale where I would be starting. I request whoever reading this mail to give your views and ideas. P.S: If possible repost this mail in the mailing lists you prefer appropriate. I do not know anyone in the field of software or startup as of now. -- Regards P.Arunmozhi Twitter: @tecoholic Website: http://arunmozhi.in ___ ILUGC Mailing List: http://www.ae.iitm.ac.in/mailman/listinfo/ilugc

I think by console you don't mean an nCurses UI? If you want to write a simple read input from user by presenting a menu, select an item and print some results then it is just like any other language like perl or C. Is Python the first language you are learning? On the other hand if you mean nCurses then I do know Perl nCurses. I am sure there must be something for Python as well. I do not believe that GUI needs bitmapped displays.

Whether you like it or not, whether you accept or not, FOSS is the driver for every company; regardless of what they are into. FOSS is all over. Just that many will not be open about it. But as a biz I suggest that you keep tight lipped about FOSS. People know it anyway; being open about it cannot help you in any way. Or even hurt. But companies want support, companies want something real. There are many ways to make money but make sure you choose something you really enjoy. Choose something where you can learn a lot , have fun and struggle. No point in picking low hanging fruits. If Arun can so can Girish. It is pointless. Pick up some area where you have something special. > 3. If there is a possibility to survive. Are we going to be judged by > the work we do or by the industry experience we have or supposed to > have? (Remember I am still at college) You are judged by several factors many of which you have no control over. Why even think about it? When I first started writing articles many years ago I never thought. I had knowledge which I wanted to share. I gave a very small writeup to my boss in pencil and he did not even care to comment. I did not lose hope. Two years later I found that everything I wrote got published. I was not a newsmaker or an opinion maker and even today am not. But I made quite a lot of money in writing. It is all about confidence, knowledge, hard work and what you feel within. No external entity can instill that confidence. It comes from within after worldly success which comes from out. Now to answer your question, certainly your reputation and credibility will count. Today nobody wants to know whether I am a fresher or not. Perhaps it is due to my grey hair or appearance or whatever. Or people just know that I have nothing to do with any college. ;) I think this is not even a point of consideration. What people think. Now as a company you sure need to manage perception. Coming to that you need a very professional looking website, very high quality brochures and so on. You need very high degree of professionalism and diligence. Get well wishers, God fathers and good friends who can guide you. Without all these things nothing is possible. Get helpers. Get helpers. People who will help either for money or otherwise. Either way get them. And build contacts. Good ones. Not fools. I just stay away from people who I think are not sensible. Their contacts will cause you pain. On the other hand good people, smart successful people tend to know other such souls and they will help you. Think about it. > 4. At last, how much are we going to be paid for these kind of jobs? In the beginning peanuts. But once you get more work and show customer references and once you get some name in the market and word of mouth you will start seeing some cash. But it is going to be tough for the first two years. > Keeping in mind that depends on the quality of work we do and our > ability to negotiate, I would like to know the scale where I would be > starting. Scale? What scale? How much cash you need? 2L? 10L? Or 50k? Who knows. Even today as I speak I don't have cash to pay the rent. That is biz. It is the fire within that counts. What do you mean by ability to negotiate? There is no such thing. I always find that I take up deals where I win and the other party wins. If not it does not work out for either of us. No use trying to negotiate out of business. Once again a lot of factors are at play many of which you have no control over. Just don't think of it. I am not good at negotiating; I am bold and know what I want and am explicit about it. That is my idea of negotiation. I have knowledge and I know what the customer wants

Use lookup tables. If you are using 32 bit ints to store numbers, you need a
lookup table till 12.
uint32_t factorial_lut[] = {
1,
1,
2,
6,
24,
120,
720,
5040,
40320,
362880,
3628800,
39916800,
479001600,
};
uint32_t factorial(uint32_t n)
{
if (n < 13)
return factorial_lut[n];
else
return -1;
}
I could think of one reason why you would ever want to do this is - speed.

Hello, Does this USB wi-fi dongle (RTL8187L chipset) work any better under ndiswrapper? Under the native drivers, it stops communicating after a few seconds of use. Disconnecting and reconnecting to the network will allow it to work for another few seconds. Is there any hope on this front or should I ditch this for another dongle? If so, does anyone have any recommendations? All the ndiswrapper posts I've found so far are pre-2010.
