hello every body... i am a new member.and i want urgent help.i study IT enginering(bachelor)and i have a project this term.i should research about silicon compiler.can anyone tell me the sources which give me information.i want some website that are free for download.thnx.

As many here already know, the Turing Test is a test for strength of artificial intelligence proposed by computer scientist Alan Turing. It consists of a human and a computer interacting through text (much like modern-day instant messaging). If the human being cannot tell that the computer is a computer and mistakes it for a real human being, it has passed the Turing Test. Now, many have tried (and failed) to come up with so-called "chatbots". I remember back when AOL first came out, "Smarterchild" was very popular. The problem with Smarterchild, however, was that it had simple, stored responses for a given category of questions/statements. As such, it would never add…

Hi: When I go to http://sparkingtech.com/tech-sci-news/researchers-create-worlds-fastest-internet-connection my AVG software gives an alert: "Threat detected!" "File name: sparkingtech.com/tech-sci-news/researchers-create-worlds-fastest-internet-connection" "Threat name: Exploit Javascript Obsfuscation (type 905)" Below this it is underlined "More information about the threat" Below that there is, "Process name: C:\Program Files\SeaMonkey\seamonkey.exe" and "Process ID: 2776" I click the underlined text "More information about the threat". I am then taken to http://free.avg.com/us-en/virbase?idn=%40EID_Id_exp I then search …

Is a fourth DARPA Grand Challenge planned yet?

I'm working on a next generation graphics engine at the moment. I've been thinking on this for many years and one of the most recurring thoughts with regards is on how to produce a more realistic deformation. To better elaborate on what I mean by Volumetric Deformation I link this interesting paper. Current models are deformed through the use of bones and effectors which vertices are bound and weight anchored to. The system is designed where in if a bone is to move a vertice will follow at a rate congruent to the value of the weight associated. There are a lot of problems with the current system where mesh structure tends to deform in a less than desirable fa…

Go is a new language created by Google: http://golang.org It's a comparatively low level language in a similar vein to C with a clear emphasis on speed. And not just execution speed, but also compile speed: wwoWei-GAPo As someone who would love to see scientists abandon horrid old monstrosities of programming languages like Fortran, here's another contender to add to the list. Oh, and did I mention it's garbage collected? Personally I can't see myself using it, but hey scientists, go nuts.

I am working on the relational schema of a table from a design that we have been given along with two other people and we have come to a stalemate sort of scenario as both are arguing that we have designed the tables correctly despite two completely different designs. I would be very grateful if someone here could look at the attached document which shows the question and then have a look at the two answers that I have posted below and tell me which one is on the right tracks. I would greatly appreciate your help in this matter, I am not looking for anyone to do any work or point out any errors just which of the two answers is closest to the correct answer. T…

The MATLAB website states that "the number of arguments is negative if the function has a variable number of arguments" when I use nargin to test such functions. So when I enter nargout ode45, I get -5. But why is the absolute value 5, does that mean it's the maximum number of outputs that ode45 can release? It is not a random number because I keep getting the same result after typing in. Does anyone know why this is happening? Thank you

hii ev1 .. i m pursuing my majors in computer science. Currently i m in the 1st year .. can someone suggest me good references/practice questions for writing algorithms ?

I know that each pixel is composed of 3 subpixels. But what are the three subpixels on the screen made of? What is their internal structure?

What can be done to protect us from the dangers associated with the TECHNOLOGICAL SINGULARITY ? Apparently, many reputable scientists believe it to be all but inevitable. Please go to: [ http://en.wikipedia.org/wiki/Technological_singularity ] for an interesting and informative discussion by many reputable scientists involved in this research and other scientists who voice their concerns about this issue. I have expressed my concerns in the thread titled: "The Technological Singularity: All but inevitable ?". I have NO answers to this vitally important question. I am not a computer scientist nor am I knowledgeable in any related fields of scientific endeavor. I am …

Could you get rid of a motherboard and instead just have a giant processor full of cores? You could have the cpu, ram, and a hard drive. Maybe those can be gotten rid off in place of just a big chunk of flash memory and a cpu. Heck it could probably process in order to maintain a certain temperature even. All of it could be intergrated into the monitor or even maybe the keyboard. What I mean is the motherboard is a series of components, like a cpu for example. Why cant all of that simply become integrated into a huge multicore processor? I think that would be neat is all to try. One thing I can think is that different programs would behave differently on it I …

In the book Liquid crystal display drivers: techniques and circuits by David J.R. Cristaldi, on page 210 they mention something called an offset compensated redistribution DAC? Could someone explain what an offset compensated redistribution DAC is?

Dave Thomas of the Pragmatic Programmers recommends learning one language a year (although probably doesn't himself) What's the next one you're interested in learning? While I'd really like to learn Lisp or Scheme, I think the next one I'd really like to learn is O'Caml. At one point I tried to learn plain vanilla ML, the language that O'Caml's ancestor CAML is based on. O'Caml was created by functional programming wizard Xavier Leroy, and combines modern declarative FP approaches like pattern matching with an extremely fast runtime. O'Caml has seen extensive use on Wall Street for stock market analytics, and was also used extensively by VMware for virtual serv…

So, I was shopping around for flash thumb drives (my old 256MB one was too small), and out of curiosity I looked for the highest capacity one I could find. As far as I can tell, it's 256 GB, currently. This prompted two immediate questions, for those more tech savvy than myself: 1) Is the skyrocketing capacity/plummeting price likely to calm down anytime soon? 2) Why are we still using hard drives with moving parts, that are slow and seemingly always the first part of any computer to malfunction? Is it just price per byte?

Hello, I am familiar with all of the common byte sizes and most of the generally unknown ones, but I have a speculation. The terrabyte is mainly used for extensive personal files and small servers, but petabytes these are used in the larger internet servers. In fact i have actually found an 8 petabyte HDD tower on ebay for an interesting sum, 10 million USD. Actually I set the item to "watch" and incredibly, it sold. With all of this one could infer that in my life span (I am a freshman) that large files such as movies or video games could encompass a whole terrabyte and petabytes could be today's equivalent of a terrabyte. Frankly, I could rant on about exo…

Many renowned scientists believe this event is all but inevitable and that the consequences of it are so far reaching that it will change our World profoundly. We will be living in the post human era if we manage to survive at all. Others argue it will go a very long ways in solving mankind`s most difficult problems and may even lead to human immortality. This event is predicted by many to occur within 5 to 30 years. Many of these scientists I am refering to are some of the most res…

If you want to write a formal specification of a program written in C++ or Java, then how can you know the logic of the C++ program you've written? I searched the Internet for books which rigorously teach the subjects of semantics of programming languages and formal specification and I couldn't find any and the three I did find are not rigorous and are quite out of date. Merged post follows: Consecutive posts mergedI'll phrase my question differently. Let's say I wrote a program in C++. How do I create a formal specification of the program I've written? Two popular specification languages are the Z notation and VDM (Vienna Development Method). So if I wr…

Does anyone know what arithmetic would I need to perform to change COMPUTER into computer?

I recently started moderating a new discussion forum which covers spiritual subject matter. I would like the forum to appear on the top of the page when a user types 'Spiritual Forum' into Google search. I'd like to discuss the way this is achieved. I don't know the first thing about it at this stage. How does one ensure a successful and effective Google search in these circumstances?

Hi Guys! Please advise something great (fundamental, must know, interesting etc) to read about algorithms Thanx!

Hey all, I've recently started to delve into genetic algorithms, and things associated with them, including alife. In my searches of the internet, I stumbled upon Floys, a simulation of creatures that share some characteristics with living creatures, among others "the social tendency to stick together" and "being territorial animals that defend their territory against intruders". There are two other, more advanced versions, other than the basic one I link to, called iFloys (Individualistic Floys, having individual personality) and eFloys (Evolving Floys, evolve by genetic algorithms) . You can find links to those two on the site. I find this a very interesting ide…

Hello Everyone, I have big problem and need solution. I am not able to start My XP. I have install dual OS XP and Fedora. I have deleted the XP's C: drive where It was installed. Now the problem is that I am not able to reinstall it due to fedora's Non Dos partition. I want to delete the Non Dos partition and install XP back.. I dont want to lose my data on other drives like D:,E:, and F: .. Is there any solution to delete the fedora an can get my space with XP back???

Hi: I'm looking for a laptop that: 1. Is fully-compatible with the Linux Live CD and does not need any HDD or any non-volatile RAM. 2. Uses dynamic RAM for volatile memory with no static RAM at all. 3. Has a wireless internet card in it. 4. Is new and not used. 5. Compromises* among the following: 5a. Least expensive 5b. Has the most amount of volatile memory *I say compromise because usually if the system is less expensive, it will have less memory. So I am looking for the least expensive with the most amount of memory [dynamic volatile memory] for the price I'm paying. The reason I need so much volatile memory is because I don't plan t…

I would like to anounce the release of the tccrouter project on sourceforge: http://sourceforge.net/projects/tccrouter/ This is a modeling tool for solving graph related routing problems, it should be very usefull for universities and students of computer science. It has a nice collection of complex algorithms implemented, and the user can extend the tool to implement his own solutions.
