Computer Science

Hey guys, This is my first ever post on science forums, I wanted to know the opinion of the professionals on a matter, I am doing my BS in CS, and in the coming semester I have to choose between two courses, 1) Compiler construction and 2) Data warehousing. I need someone to give me suggestion and explain it as well. Thanks.

Will quantum computing be a whole new "species" of computer, what I mean by species is will quantum computers be totally different than the computers we have today such as a whole new architecture. The qubit is really mind boggling. What kind of applications will quantum computing bring. Thanks

Hey, For my subject Computer Science I need to write an essay about Algorythm. I looked up on different websites but I still don´t really understand it. Can you please help me and tell what it is or what it is usefull for or where it is used. If possible not in to complicated language because I am not that good in it:) Thank you BTSVCHRIS

These two videos worked. Normally, it displays a message saying I need to install a Flash plugin, but instead it played the video using HTML5 technology. Awesome! http://www.youtube.com/watch?v=kmk43_2dtn0 http://www.youtube.com/watch?v=ESZ3NFL8X-k But unfortunately other videos there are still in Flash. Just want to know in case I upload videos, I'll make sure they're HTML5 playable. I used Firefox, newest version.

I have searched google for this but cannot find... is there a video chat site that lets you communicate with random people like chatroulette but by subject.... Kind of like a subject based forum like science forums..but once you click on a subject you are sent to a video chat instead of a forum?

HI, I'm phd student, have dataset, I'm working in sequence alignmnet. So, need a way to encode my data then make alignmnet. the range of my data between 1-11000 i.e if I need unique code for every value in my data I need large set of characters can I use unicode for encoding my data? is so, give me link, and a way of represent my data. thanks

how do i mastering a programming language ?

Hey all, Our lecturers have provided us with an assignment where they want us to read in a file they've supplied in a certain file path. They want to be able to type in the file path through a standard input function. I have set the code up but whenever I run my code the program prints out the prompt for input but then skips to the next printf() statement. Here's the code: location *nav_information; ship *ship_information; /*instance of the struct in 'resources.h'* pointer needed for dynamically sized array */ time_format *times; FILE *fp; fp = fopen("LOGFILE.TXT", "w+"); /*this is the logfile we will write ship information and collision information in *…

Sometimes if you use the "free" WiFi service of an open internet wireless connection, you get redirected to their webpage instead of your homepage when first opening your internet browser or trying to go to a webpage. How do they accomplish that?

I have an RFID reader and an rfid tag. The tag has a feature where I can set a single bit to either 1 or 0 depending on its status. Its memory address on the tag says "200h". What does that mean? How can I write a macro on the reader to change the tag to "1" when sold/scanned, and "0" when returned/scanned second time?

Hi friends! Do u have a basic ideas about speech recognition in tamil language? Pl share with me

hi, I'm working in sequence alignment. I would like to know how I can determin the scoring matrix? thanks in advance

Hi I am planning to pursue my higher studies, thought it would be better to find out on some of the latest research topics in the above area.. Any ideas on whats the hot topic.!

When we go through any steps in websites like:making profile in any site,commenting etc.They ask us to recognize the letters from a picture and type that correctly.Whats that for?

I have to write a program where I take user inputs and draw fractal images (preferably Sierpinski's Triangle) using some code already provided. Problem is, we haven't even talked about fractals. I guess my question is after obtaining coefficients from the user, the number of functions they want to use, and the probability associated with that function, how would I continue to build the image?

WHAT IS POWER OF DETERMINISTIC AUTOMATA AND POWER OF NON-DETERMINISTIC AUTOMATA ?

Are we going to be seeing a trend towards cameras that produce stereoscopic stillframes? I haven't seen or heard anything yet about a move towards a new format. How would everyone feel about such a move? This would be especially exciting if still's could be printed in full colour spectrum holographic, which they can't. I wonder when professional photographers will make the move. . . . . or at least offer the option! 3D Stillframe picture viewers lol . . . .
