Computer Science

Any gamers around here? I'm looking to buy a good quality sound card but would like to hear some input and maybe some suggestions.

hi, I have to use newman algorithm in my work in PhD thesis. I have no idea about it. so, I would like to know : is newman algorithm clustering method or it is used after clustering method to remove the edges? thanks

Im doing a project on Online library card allocation system.kindly suggest a research area

Hi folks What do U think about this concept for infinite list browsing? Items move around central circle on dragging them. Might be implemented as a cell phone menu browser. If U'd like to play with a prototype, please follow this link: http://styled.host-e.../bloss-aio.html Please feel free to use the concept without *any* restrictions

Which books can be followed for studying the following subjects in computer science: Data Structures Algorithms Computer Networks Computer Organization & Architecture Operating Systems Database Management Systems Any books and also web links....

why buy something when you have the knowledge to make ,develop and create . how can it be more done?where to start?what exactly to start? share your ideas!!

I'm currently a Computer Science student that wants to get a job at northrop grumman. I've applied (multiple times!) for internships through their company website, but I can't seem to get my foot in the door! I'm told that you must know someone at the company and get referred in order to get a job there. I want to work in the unmanned aerial division - does anyone have any tips?

Hi all Remember that old money cache mechanic sum/multiplication machines in big modern stores few decades ago? They looked like old funny fat typing machine, they had big number keys and mechanic bearing on the right side. Ant that was working on the cache machine would enter a price, turn over the bearing, enter another price, turn the bearing again, ..., and at the end, ant would turn bearing twice and she would have sum of entered prices written on mechanic display on the top of the machine. Those were days... A while ago i came up with idea of making a special kind of visitcard (U know, a little peace of hard paper that business people use to exchange their ph…

http://www.fastcompany.com/1821378/the-greatest-innovation-yet-making-computers-quantum-could-change-the-world 101010: That's the number 42 represented in binary, which is the mathematical way today's binary computers see every single piece of information flowing through them, whether it's a stock price, the latest Adele track, or a calculation to generate an MRI of a tumor. But now IBM believes it's made progress in developing quantum computers, which don't use binary coding. It is not overstating the matter to say this really may be the ultimate answer in computing machines. Quick, mop your brow and don't worry: The science isn't too hard to grasp and the revolution…

The BBC's report: http://www.bbc.co.uk/news/uk-18867643 Some might say fair play to them; if people are hacking "UK Networks" why shouldn't they return in kind? Although to me, it's a worrying idea, that the UK government will be hacking it's "enemies", who, as usual, have not been specified sufficiently. As if it's not bad enough with the current police-state-like monitoring of the internet, but now, the UK will be attacking-actively defending- as they worded it, anyone it deems as a threat. Which I will stress again, is only ever loosely specified. It's giving too much power to the government, yet again, and by my book it is them trying to police the world; in the same…

Hi All, I have a very basic question on integrating two applications of different technologies. Let's take a web and a mainframe application, and we all know this could be integrated through 'web services'. But is it possible to integrate these two applications without using webservices; i.e. by using a simple XML and having a parser program at both the ends? Is it possible to build a online or batch interface using XMLs in above case, if yes, any specific factors related to technology should be take care? Thank you.

Hey! I would need some help! ls it possible to access .img files (Erdas Imagine) with programming languages C and R. If then.. what would be the code for it? I tried to search it online but couldn't find anything. I am myself not familiar with neither of the programming languages..Hopefully someone will be able to help me. Thanks in advance

As of late, I've been reading a lot about the Playstation 2. I have a Playstation 2, and I've been using the PCSX2 emulator as of late. I got quickly annoyed by my situation to not play Devil May Cry 3: Special Edition when the emulator did not quickly play the game. I figured that my computer processor and the graphics card is much better than the graphics card and the CPU in the Sony Playstation 2. So far, I've learned that Playstation 2 has a graphics synthesizer that appears to process the graphics much better than some modern graphics cards. I haven't been able to understand this. But I believe the reason for this is because of the architecture of the Plays…

Samsung's boffins have made a breakthrough when it comes to a new transistor structure which utilises graphene, in research that was published online in the journal Science. The company claims the advance brings us one step nearer to replacing silicon transistors with graphene. As Samsung notes, the industry has been increasing the speed of devices - the performance of semi-conductors - by scaling down technology, reducing transistor size and the distance electrons must travel. However, the potential limits of such scaling down are being reached, scientists reckon. And a switch to a material with higher electron mobility - which also allows for faster electron…

Me and my bro are connected to the same network. He and I have windows 7 ultimate that has msg.exe. When i try to message him it says 'does not exist or is disconnected'. I dont see why this is happening. Any help would be great. Thanks

I would like to perform some calculations based on mathematics or algorithms or real-time values (like sniper websites for ebay, etc.) on the cloud and the results need to be sent to the user's computer. Are there any specific names for the servers that perform such operations on the cloud? My next doubt is, can I use my Tablet or Laptop to operate as a server and perform such operations Since I don''t have much knowledge in these topics I have questioned in best possible way to be easily understandable. Regards

First I must say that I'm quite a newbie in C programming.I've made the following program for practice with note reading: http://www.dpaste.org/3V2fc/ As you can see the idea is: 1) to produce a random note on a staff. Simplest way is making it visual and shaping it by using lots of these - and O for the note. The randomness is achieved by placing a number to each staff (i.e. note), and running a random function covering each possible note/number. At the same time in each staff the note determines the value of the variable 'truenote'. 2) to ask the user to find the note. The user can type in the notes A,B,.., G and for each note a number is given to a variable 'n…

I am studying Boolean logic gates at present and I was dreaming of having my own circuit board with a few gates to experiment with, then I realised that a laptop should handle the job could anyone recommend a 'virtual circuit board' app where you can attach inputs and outputs of various gates and see the results in terms of 0 and 1's? thank you

I am about to learn programming. Will somebody give me a good online resource or some free eBook for learning "only BASIC" K-12 level C++. Furthermore, "Borland turbo c++ 4.5" should support it. I want to do this so that I can get a head start in my class.

I know that there are many researches about it but I just wanted to know your opinions. Technology is our everything (cellphones,computers,programmes,, etc.) anyways it's making us lazy and insensitive? If there was a 'dependence test' , how could be its questions ??

As the title says, investigators now believe that Alan Turing's death may have been accidental. Interestingly, the apple found at his bed side was never tested for Cyanide http://www.bbc.co.uk/news/science-environment-18561092

so lately I've been studying randomness for no particular reason. the problem with most prng is they use both multiplication and modulus, both expensive, and are not necessarily very good at producing randomness. i believe i've come up with a nice, compact pseudo-random number generator. here it is in python. v = [0]*3 seed1 = 1995714531 v[0] = 0x96696996 v[1] = seed1 v[2] = 0xb5b5adad def rot(x,k): return ((x<<k)|(x>>(32-k)))&4294967295 #the &num is unnecessary in other programing languages def rng(): v[0], v[2], v[1] = rot(v[2],8), rot(v[1],17), v[0]^(~v[1]&v[2]) return v[1]

Design the instruction format of a system with the following structure i.16 registers ii.16 word addressable memory of 64KB which is to be extended with a second module of same capacity iii.Seven instructions with one memory address and one register,31 two register address ,7 instructions with one register address and 10 instruction with 0 address.Specify the format of each group of instructions.Do you like to have any NOP?justify

A 4-stage pipeline has the stage delays as 150, 120, 160 and 140 nanosecondsrespectively. Registers that are used between the stages have a delay of 5 nanoseconds each. Assuming constant clocking rate, what will be the total time taken to process 1000 data items on this pipeline?

Hey, I'm a first year going onto second year shortly computer security major. I'm not the best at math (meaning I don't get the best marks, not my favourite subject) my university only wants 4 courses which are pure math for my degree. Since I'm not the best at math I'm not that interested into it and don't like it. But, I LOVE computer security, networks, malwares , attacks etc including programming.. what Im trying to get to is, do you NEED to be as good as you can be at math considering it's based off math? For me math is just something I have to put up with because I love this job and what goes on in it, I currently know java full in and out. What do you guys think? M…
