Can someone link me to a good website that can teach me the basics of flash programming? I just joined the html programming club but I want to do flash too and I would feel kind of out of place if I joined with absolutely NO knowledge about flash at all. (a website with programming language tutorials would be nice too) By the way, PLEASE don't post a link to a tutorial on how to make specific affects in a flash game.

For those of you who may remember me I've been off the radar a little since I moved out of my Uni Home and down country and waited patiently for BT to install a substandard internet connection. - Now they have I'm working on a project and i could do with a few questions answered about your Mobile devices. - Preferably Smartphones i.e. Windows/ Symbian / Palm powered but anyone with a phone should be able to answer these. Its going towards a project concerning productivity using mobile devices and how it is affected by data input methods / interface. Here I’m just trying to identify if there is a case. If you want you could post replies in this thread, email to sur…

Hi. If I have a global positioning satellite receiver GPS on a laptop USB port, and also a video input fed to the computer; How to stamp latitude, longitude and heading on each video frame recorded in the hard drive as to log images location for a towed submarine camera ? To make it harder; if the camera is towed 100 horizontal metres behind the boat, how to compensate the stamped readings for accuracy at all headings ? Miguel

Science Daily — Computer scientists at Harvard's School of Engineering and Applied Sciences, in collaboration with colleagues from the Netherlands, are using a novel peer-to-peer video sharing application to explore a next-generation model for safe and legal electronic commerce that uses Internet bandwidth as a global currency.

Are there any legitimate programs that can actually encrypt PHP so others can't read the source if the file is distributed? There are so many programs that claim to do this, but each one I've seen can be decrypted easily. They have layers of encryption, but the source code can be seen by simply decrypting one layer at a time. Simply echo the final result instead of running it as code. The ones that generate unique keys for each file do not help. The key itself must be somehow distributed with or in the PHP file. I haven't seen any methods to prevent a good programmer from eventually reaching the original source, even if it takes a while to do so. Is it possib…

more or less than 500 teraflops?

Controversial Artificial Intelligence researcher Hugo de Garis tells us his thoughts about American science, "brain building," and superhuman intelligence in a new interview which can be read here.

Interesting article in today's New York Times about the push to recruit more women into CS programs. http://www.nytimes.com/2007/04/17/science/17comp.html?_r=1&8dpc&oref=slogin I think they're right on target, and I've heard that many CS/IT programs around the country (including mine) are facing serious enrollment challenges these days. What do you all think?

Very often, I noticed that there's a file type nfo in CD. What's the use of the nfo file?? It occupies only a very subtle space.

Since people asked what happened to the SFN Brain Challenges and since the number of participants in YT's "build something"-challenges is approximately zero I've thought that a litte JAVA programming exercise might suit the SFN members better. So here we go with a little programming challenge. GOAL: - Create a program that calculates factorials. TARGET AUDIENCE: - Anyone with zero programming experience to experienced programmers. - For complete beginners, I'll post some startup tips so you should at least be able to get a program with limited capabilities running quite easily. RULES: - Challenge will run approximately 4 weeks. - The structure of the mai…

Okay, not really, but this is sure a big step forward in intelligence research: http://numenta.com/ Numenta, a startup company founded by On Intelligence author and Redwood Neuroscience Founder Jeff Hawkins has released both binaries and source code for their general intelligence algorithm, known as Hierarchical Temporal Memory. This software is based on the behavior of hierarchical networks of neocortical columns in the brain, which Hawkins theorizes provide the foundational components of human consciousness.

Are there any dangers to multi-tasking on the same computer? For example, if I was logged into a banking web site, could a malicious web site opened in another browsing window possibly steal any information I'm working with in the other window? I'm using Windows Vista, which is much more resistant to malicious code than Windows XP, but are there still risks if I multi-task?

i've looked into altering some code (mainly for learning), but my god is it a morass of confusion if you're a noob Does anyone know of a simple, prefferably python, program with moderately simple code (no heavy maths, no millions of files, no complicated programming techniques) that's good for a noob to pick up an alter to get a 'feel' for it? nethack and Aspell would be good examples of what i'm not after mainly, i want some practice with compiling, making and using diffs/patches, etc, and basic experience with finding my way around someone elses code. it doesn't need to be a program that i could make useful modifications to (tho i suppose a simple program with…

Hello, I've been interested in computer science for quite some time now but have found it relatively difficult to find the answers I'm looking for without asking somebody with a phd.I keep wondering what happens to a computer when you click on a file.I already know the basic answer "oh yeah it reads from the harddrive that's where the file is stored".But I need to know more details than that.I'm looking for the nitty gritty.How did humans manage to be able to tell a computer what to do when I click on a program? I know electricity shoots down into the computer in a million different places but I'm missing the "inbetween".How does it interact with whatever you're …

can anyone tell me if they are any differences between a lan card and a wireless lan card, offcouse a wireless card does not have any wires but are they any other differences, the reason why i ask is,,, my friends and i want to set up a local network in our city to play video games with eachother, basically there are 16 of us, our houses are scarted around in something like a 1 square kilometer radus. Can anyone tell me what would be the cost of setting up such a small network (in terms of users) yet big ( in terms of distance) network. Next, i have setup networks with lan cards in the past and it has worked out just fine for me, does this mean that i will be ab…

Recently, I saw two types of file in the internet. One is HDTV and the other is DVDRip. What is the difference between them? What about the size, the operators, the quality, the sound? Thanks

is it realistic to expect biologists to study evolution eventually through massive simulations, to learn how complex structures such as (insert creationist claim here) could have come about through Natural selection? i'm talking about a simulator that would have all the detail of the real world - from organism down to atom, along with all their interactions, in entire virtual ecosystems of hundreds of individuals in turn belonging to hundreds of virtual species, all interacting. how far away are we from that level of simulation in terms of our computing power. is that level of detail in a simulation ever attainable? if it is, it could IMHO finally put to rest the clai…

I don't really understand the problem described in this article: http://news.bbc.co.uk/2/hi/technology/6265976.stm They seem to be saying that the contents of a document will be lost if nobody is able to find a copy of the software that was used to create the document. In all word processing programs I'm aware of, the text itself is stored as plain text within the file unless you encrypt it. You can open an old Word document in Notepad and still retrieve the text. You would have to set the font and style information again, but why is it such a large problem?

I have a large list of words, with several duplicates, so i wrote a small python script to generate a list of all the dupes: dicnohash = the list dups = the list of duplicates in the list dups = [] for a in range(0,len(dicnohash)): for b in range(a+1,len(dicnohash)): if dicnohash[a] == dicnohash[b]: dups.append(dicnohash[b]) break it just compares each item with each item after it, and if they match, it logs the match in the dups list (which is later written to file), and then breaks to the next item in the list. however, there are nearly 100,000 items in the list, so i guess it's going to do a max of somewhere in the range of 5,000,000,000 …

i'm a freshman in college and when i go to present programs to my teacher it doesn't load with the complier on the school's computer . i wanted to know what is the best programming compiler and is there one compiler that is compatible with other compilers as well.

British artificial intelligence researcher Paul Almond has a new on-line interview available, in which he says: "We had optimistic expectations about when true intelligence or sentience would be achieved in artificial devices, but I think that it is possible. Intelligent machines already exist -- ourselves. The fact that matter can naturally come together to make things like humans that think shows that the process can be replicated. Of course, people argue against this. Some people say we have some kind of “immaterial” or “supernatural” soul. I think that is an incoherent concept. Roger Penrose and John Searle both argue against artificial intelligence using compu…

http://news.bbc.co.uk/2/hi/technology/6742439.stm anybody try it yet? They claim it's two times faster than internet explorer. I thought that speed dependent only on the internet connection speed... how can one browser be significantly faster? How does it compare to firefox?

i have an 80GB storage unit, and i had a few questions as to the potential applications of it. my idea is to partition it and put an OS on it. in theory, i could use my storage device, then load the OS and use applications off of it (internet, games), without school/library/wherever having record of my using them, or the internet history. as i said, this is my theory. would it work, though?

I've been glancing over the python programming language recently and i've worked through a few beginners tutorials and i get most of it. i'm just wondering if there are any sites out there with sets of problems along the lines of: write a program to do X. then maybe example answers if you get stuck. i've had a bash at http://www.pythonchallenge.com/ but i can only get to level 2(it's actually the third, it starts counting at zero) where i can get an answer but i don't know what to do with the answer. in other words, its far too hard for me just now. any help would be appreciated especially if you can explain classes to me in teeny weenie words as i ca…
