Here are a couple of reference articles on this subject: http://www.techworld.com/mobility/features/index.cfm?featureID=3465&pagtype=all http://www.networkworld.com/news/2007/061407-wwdc-developers-split-on-iphone.html In a nutshell, developers are unhappy that Apple has not provided the ability to create 3rd-party applications for the iPhone, which is due to be released in a few days. This is actually mostly about money, because Jobs has said that he does want to provide this ability eventually, so mainly developers are upset about not being able to get in on early popularity. But there are some interesting twists to this story that I think have a larger cont…

I wrote a prime number generator (sequential) about 20 years on a BBC micro. naturally it`s in Basic, can anyone check it out on a more Modern system for me to make sure it`s a good prog? I`ve managed to resurrect it from a 5.25 inch floppy and it`s working but I don`t know if it was ever any good to start with! 10 FOR A%=1 TO 65535 STEP 2 20 FOR B%=2 TO A%/3 30 C = A%/B% : D%=C 40 IF D%=C GOTO 70 50 NEXT 60 PRINT A%; 70 NEXT A% as you know the % forces Integer. can this be improved upon in anyway? or made faster? I chose 65535 as that`s a nice 16 bit number and wasn`t interested in going beyond that in primes, I use this prog and stop watch as a be…

My gosh, this was too easy. This was a Windows installation and it's very user-friendly. I'm fairly new to Linux, but I thought I had it made with Suse, even though I have not tried the latest version. I've only used the command line once, to get this radio station to play that Mplayer will not pick up by default.

Erlang is slowly gaining in popularity. This will hopefully speed up soon, because the Pragmatic Programmers are releasing a book on it: http://www.pragmaticprogrammer.com/titles/jaerlang/ What makes Erlang so awesome? The Actor Model - Like objects, but they all run at the same time... across multiple CPU cores or multiple computers. Think of a language where every object is also a thread. Implicit parallelism! Hot swappable code - Need to update one small part of a large application? Particularly a network service that a lot of people are connected to? Drop it in on-the-fly! Network transparency - Throwing more CPUs at a program was never easier…

Hey, I was wondering if anyone knew the command codes to type into run directly to bring up remote desktop connection. I live at a college at my University. I like to remote desktop my PC, so I can continue working on whatever I was doing at home between classes. Though I dont know if it will work due to restrictions on our systems here. They are quite annoying indeed. It seems they have restricted access to the cmd box. *sigh* but they have the run command box, so hopefully it will help. Thankyou

I've just started learning java, and i'm finding the indentation of the {}s a bit hard to follow (i.e., i can easily imagine missing closing a {}). basically, for the following: /** *quick learny thingy */ class TestApp { public static void main (String[] args) { System.out.println("I have written a thingy! :-)"); } } I have a really strong inclination to write as: /** *quick learny thingy */ class TestApp { public static void main (String[] args) { System.out.println("I have written a thingy! :-)"); } } My question is: for someone who's experienced in java/C, would the latter make it harder to read or not really matter? …

The Visual Basic web control component uses the Internet Explorer core. The Vista version of Internet Explorer 7 works great with Vista's protected mode, but there are a lot of security problems with the XP version. Would it be possible for my applications to use the Firefox core when running on Windows XP, and the Internet Explorer core when running on Windows Vista? I'm not sure how to get the Visual Basic web component to use the Firefox core instead of the IE core. Is this even possible?

Please compare the features of both Operating system, Windows Vista and Mac OS X. Features in term of functions, technology, reliability, compatibility, scalability and cost.

I,ve read over the internet that windows vista prevents users from playing illegal mp3 or video files. and there are many other roumors reagarding to DMR and i was wondering, how much of this information is true?

Does anyone here have any experience in programming video games of any sort? I've had a couple of ideas and reading those "Teach yourself Java" books, but experience is showing that this making a game is really, really complicated. I'm trying to make some sort of TBS (Turn Based Strategy).

I was reading an interesting article at http://money.cnn.com/magazines/fortune/fortune_archive/2007/05/28/100033867/index.htm that says Microsoft claims Linux and other free software programs are violating its patents. If it can, Microsoft may be planning to demand royalties from Linux users and distributors. I wonder how this could affect the prices to host web sites on Linux servers? Also, isn't Apple's Mac OS probably violating many of the same patents as Linux?

Hi all, What about programming? These days they are very rare that works in programming! I even failed to get any successful connection through the internet to buy a VB.Net Compiler. Does anyone know why?

For anyone who doesnt know what pascal's pyramid is: 1 1,1 1,2,1 1,3,3,1 1,4,6,4,1 1,5,10,10,5,1 etc. So I wanted to make an excel sheet, where the two values diagonally above add up for the value underneath. Is there any easy way of doing this? Something like, all values selected are calculated by value 1 above and to the left plus value 1 above and to the right... or something along those lines. This would be so much easier then doing it for each box seperately.

A person at work turned on his laptop this morning, and he was unable to see anything on the right side of the screen. This is what the screen looks like: The left side looks normal, but the right side looks like this from the moment I press the power button. The screen doesn't appear to be physically cracked or damaged. He said he used the laptop a lot this weekend, and he doesn't remember dropping it or anything. When I connect the laptop to a monitor, the screen looks fine. Has anybody seen anything like this before?

As all of you know, the rate at which technology advances is increasing. There is no possible way that one can just study all of the engineering aspects of the new technologies in school; Or can they? I'm not in college yet, but I'd like to know how CS, CE, and EE majors learn how to work with all of this new technology? How do you know what hasn't been invented if you don't know about the new technology being presented to the world everyday? Do the instructors teach you how to adapt to new types of mechanisms involved in engineering the new technology we see today, rather than teaching you one thing and expecting you to get ideas off of that one philosophy? Both? …

Seth Lloyd gave it a thumbs up: http://discovermagazine.com/2007/may/quantum-leap It's 16 qubits now, but the creators say they can expand it to 1,000 by next year

I need help in design algoritem that check for a given Graph if a minimal spanning tree exist without a specific edge. Mean that for the original graph you find a minimal spannig tree and that spanning tree not include the edge and it is minimal spanning tree of the graph that do include the edge. The algorithm must run in O(|V| + |E|) when V - vertics and E - edge Thank for any help!

I am having trouble accessing certain web sites, including ScienceForums.net and my own dedicated server. This has happened before, and it can sometimes take several days before I can access them again. When I ping ScienceForums or my server, all pings are returned from the correct IP addresses. However, I am not able to load anything from them in a web browser. I've tried using Internet Explorer and Firefox with Windows Vista, and I've tried Firefox with Linux on my other computer. None of them will load anything unless I use a proxy server site, which I am using now. I contacted my ISP, and they said their DNS servers are working. They said it isn't their p…

I am putting a lot of data into Microsoft Excel that needs to be squared and totaled for a scientific experiment. However, the numbers I get from Excel differ significantly from the numbers I get from a graphing calculator and the scientific calculator in my computer. When I try 0.18^2 in Excel I get 0.0316 but I get 0.0324 on a calculator. When I add all the numbers together, they aren't even close. I've tried changing the number of decimal places in an Excel cell, but that doesn't make a difference. Does anyone have any suggestions?

crazy idea... Imagine 3 houses next to each other. say the each have a wireless router connected to a different ISP, and each house has 2 computers with wifi cards. house B is in range of houses A and C, which are both out of range of each other. would it be possible/advantageous (i'm talking theory, not current tech) to set the three networks up to co-operate, and form a small 'internetwork'? So, for example, if house A is d/ling something and maxing out their connection, and house B is currently not using their connection, house B's router could supply one of the computers in house A with internet connection, whilst the other computer in house A could use ho…

any one here have any experience with them at all? maybe even Use/Have one? how do you rate Tahni 2d for instance?

Hey guys - I need your help ! I'm currently a high school junior, and I want to be a software engineer, but I don't know exactly what to choose. ◘ What is the difference between computer science and software engineering? ◘ can somebody with a CS degree be called a software engineer? ◘ who are employers looking for now, or should I say Who are more successful? people with a CS degree or SE? How do you think it will change in the next 5 years? I'm really nervous about this and I hope you guys can clear out the mist that surrounds me with anything concerning software engineering.
