Computer Science

So I have already taken the old earth magnets out of my REALLY old computer hard drive and now I have this printer. I was wondering, before I get rid of it, if anyone knows of any useful parts inside? I am probably not going to be building any cylons or anything anytime soon so robotic parts are less useful to me. But magnets or something like that is always fun to keep around. Anyone have any knowledge of what is good to keep from a printer before I get rid of it?

i want to know about the role of mesh network in green computing

hi, I have come across applications of machine learning to finance like Portfolio, trading strategies and Consumer Credit risk prediction. What are other applications of ML to finance ? Thanks.

I have been trying to plot a number of black body radiator spectra curves in MATLAB but I come across a problem - only one curve is plotted when I run the program. Essentially, I am plotting intensity I against wavelength [latex]\lambda[/latex] for an array of temperatures from 3000K to 8000K in steps of 1000K with a wavelegnth array of 100nm to 3000nm with 1000 intervals, using Planck's radiation formula: [latex]I(\lambda,T) = \frac{2\pi c^2 h}{\lambda^5} \left(\frac{1}{e^\frac{hc}{\lambda kT} -1} \right)[/latex] where T is th absolute temperature, c is speed of light, h is Planck's constant and k is Boltzmann's constant. Here is my code: Function File …

Hello everyone I am searching for a (free) program that can compare two folders. Now I have 2 folders full of files, one original and one back-up. It it's possible to compare them with a program that would be very useful. I hope someone can help me. Greetings, Gilles

Hello, I'm a MsC Computer Science student and I really like to read some papers in the general field of computer science. E.g. I just started reading "The eval that men do", which was recommend by a teacher we have. Are there any other papers that one might recommend to read?

hi I can't figure this out please help: "Two police officers are carrying n gold coins in two bins, in a secured vehicle. The physical characteristics of the the gold coins are the same, but while the coins in the first bin are all the same, the ones in the second bin are different from the ones in the first bin. At one corner, the driver suddenly brakes and the coins are all mixed up. They have a device that can be applied to two coins and tells whether they are different or not. It is known in advance that most of the coins (more then 50% ) are from the first bin. Find the algorithm that the two officers should apply in order to put the coins back into the bins. How many …

Sorry for the double post, didnt know which section to post in. Hello, First i would like to point out i am 16 years of age, with many different ideas... and a very large mental capacity. First i would like to start off with what TRON is... based on the NEWER movie if some do not know. Here is the Trailer to the newer movie Alright now onto the more advanced stuff. In the movie they used a lazer to blast the human into "the GRID" as it would be called, but is more into the terms of a type of CyberSpace Now here is where i got to thinking. it has already been confirmed that scientists are working on things like molecular Transportation …

Can somene tell me how I'd compile this? Or guide me? https://github.com/Nebuleon/TempGBA Thanks a lot, in advance!

Hi guys, I hope to get your valuable inputs to this pet project of mine, please do feel free to mention your ideas, suggestions and recommendations for the same. This is my personal project without any academic monitoring so I am definitely looking for some guidance from your experience. I've collected a huge number of memory traces almost 10 GB of data. These memory traces were gathered from a set of servers, desktops, and laptops in a university CS Department. Each trace file contains a list of hashes representing the contents of the machine's memory, as well as some meta information about the running processes and OS type. The traces have been g…

i need a good validity index that can uniquely identify clusters based on thier density

Hey guys. I'm almost finished with my program but I can't figure out what's not working. It works when I fill in the entries in the code but when I try to use the Scanner class to have a user input the characters, and then enter a space to stop, it doesn't work. I'm guessing there's something wrong with my loop since when I debug, I can enter a letter once, it sets the first entry to that letter, but cannot keep going after that in debugger. import java.util.Scanner; public class CombinationLockTester { /** * @param args */ public static void main(String[] args) { CombinationLock lock = new CombinationLock("ABC"); Scanner scan = new Scanner(Sy…

Hi all, I know the equations and defenitions etc of entropy in information theory, but wanted to know the meaning of entropy 0.875 bits and 30 bits etc. I heard that passwords need to have higher entropy. But english language has an entropy 2.5 bits means what? What do these bits convey? -Devanand T

What is this 512x512 picture? Bad Quality Lena indeed, but the trick is that it's black&white - can be directly seen as length 512x512=32kB bit sequence. It occurs that making bit sequence "looking like Lena" reduces the capacity only to about 0.822, what is about 26kB in this case - the visual aspect costs only about 6kB. It has rather too high resolution for practical applications, but here are examples of lower resolution codes looking like a chosen black and white picture: for example the central noisy code contains 800*3/4=600 bytes - making it look like the picture costs only 200 bytes. Here is fresh paper about obtaining it (generalization …

I have a program that acquires language and responds well. It may have flaws but I can work those out when I have data. Anyway, I need help getting this program up on the internet. The sooner, the better. It's written in Python 2.7 and there are various things that I do not know and would like to get help on. If anyone is willing to help with the project, I'd really appreciate it. It needs a user interface (doesn't have to be super special although it would be cool if someone wanted to take the time to make it look good). It also needs to be accessible through a website. I'm kind of new to Python (I've only been working with it for a little over a year) so I have several …

Im a B.tech 2nd year c.s.e student. I just wanted to know in which field should I train myself in order to get placed in a good organization? Should I prefer Java/php/oracle/networking/linix ? thank you

Hey everyone! Thanks for taking the time to read this topic. I really do appreciate it. But as the topic says. What is a good programming language to learn, I kinda know Java and a little bit of Python. I know HTML and CSS are not programming languages but I know them pretty good. Thanks and bless your faces!

Hi everyone, I have a question about Microsoft Net. framework 4.0. I installed Microsoft Net. framework 4.0 on my computer from here and after the installation I see nothing: no program shortcut, no shortcut in windows explorer or anything else from which it's possible to run the program. What could be the problem here? Does Microsoft .Net framework 4.0 require Visual Studio 2010 to run or how else can I open (aka run) this program?

I have been attempting to read over literature in relation to why more video games are not made for computers. I keep finding people giving ideas and clue. However, I feel as though these people are writers more than computer program designers or engineers. In the time I spent reading over how the Playstation 1 and Playstion 2 console system was made, I read into the engineering aspects. Supposedly, the engineering went into depth so that graphics would be more easy to present at a faster rate and speed. As such, a different kind of programming language had to be made for people to develop video games for the video game console. As such, this makes me wonder if th…

Hey everyone, I'm been looking into what a platform engineer is and can't seem to find any great descriptions. Could you give me a brief description of what a platform engineer does and maybe a notable program engineer or a company that relies heavily on platform engineers? Thanks!

The solution to this problem is not very hard : you just use a combination of two kinds of technique You use a combination of search and non search , the idea is to limit the search to a managable level, a clever technique of limiting the search by using a convex hull is applied, and you do partition the search space in to a set of layered convex hulls where the computation to find the optimisation is done one step at a time, please see my algorithm description : or just type NEW ALGORITHM FOR THE TSP in youtube search

I think I have the language problem solved and I want to get the program on the internet asap. I'll share the code with whoever thinks that they can help get it up on the internet. It works well and sounds human enough. I'm willing to maintain the domain, I just need some help. I'll help with the code too if needed. It's written in python 2.7

hi friends, I am trying to develope a wide area network emulator..for which I need the source code for NETEM..can anyone tell me where i can have the source code with packeges..I got one code but its does not look sufficient..i didnot find the main function in that code..please reply and help me..thank you..

Hi, Can anyone answer the question below? A processor has a 32-bit instruction format with the following fields: opcode: 8bits ra: 6 bits rb: 6 bits rc: 6 bits rd:6 bits where ra, rb and rc specify three input registers and rd specifies one destination register. Assume the processor uses a register file (i.e. a memory block with the smallest size as required) to store the identifications of all registers, how many registers could this file hold in theory,and why? Thank you very much
