Freeciv is an awesome game (thou the ai's too hard for me, but that's cause i suck).
There are plenty of other open source games that don't run on linux that have active game creating communities with some great artists that could use help. The rpg toolkit is an open source project that's written in vb. They have a sourceforge page. I've looked at the code and there's no reason this couldn't be ported to.net/mono using the sdl. This would make it run on linux. This would give hundreds of begining game developers and artists access to a community of people (oss people) who would play their games and give them feed back on how to make their games better.
I'm sure there are other programs that are floating around that could benifit from non-windows developers looking at their code. The whole more eye's thing doesn't work if eyes aren't looking.
The whole idea of spelling is a somewhat new development. Why should I be forced to conform to a completely imaginary set of rules that do nothing but to stop us from worrying about the content of our writing and instead worry about if the style conforms to the somewhat arbitrary standards set by bitter old english teachers? You may wish to be bound by such things but I do not.
From my understanding Linux is exploitable by the same class of bugs. The only difference is instead of attacking the heap via IIS you attack the heap via PHP or ImageMagik. In Windows you want to overwrite the little descriptors at the bottom of the heap. In Linux you want to fill the stack with junk till you hit something you can use, at least it was last time I checked.
I really would like to understand how Linux stops something like that from happening. It would make me feel ever so warm and cuddly.
So if I'm understanding this right, Linux has some moderate protection for the stack that is breakable by just filling the stack with junk until you hit something that's going to be executed? But that doesn't protect the heap and it sounds like the stack is still exploitable, just in a different way.
This isn't very good news at all.:(
By the way, thanks for answering my questions. I think I have a better understanding of the problems described.
So Windows could be exploited by this but how does Linux not get hit by this. My memory on os design and assembly programming isn't what it use to be, especialy since I do mostly web apps these days and avoid lower level things like the plauge.
What does Linux have in the way of heap protection? The NX bit is on AMD 64 and Itanium chips only (as far as I remember), so what's to stop this from working on any x86 based OS?
On a sidenote, I've always wondered how Linux protects, or doesn't protect, it's exception and interup handlers. After briefly dabbleing in User Mode Linux I've had this sinking feeling that my box never could be secure from this sort of attack.
Is it just me, or does this article lack on the business plan side?
I've been looking for a way to start an open source project that can pay my rent for years. Still haven't found a way short of witting something everyone needs that doesn't yet exist and then sell it with the source being open. I'd love to rewrite the gimp's ui code to make it usable, if I knew I was going to be able to at least pay for a sixer of beer because of it.
How does a poor starving geek turn his oss hobby into a rent paying business? That's what I like to know. We aren't all in high school you know. Some of use do live outside our mother's basement...
So it's going to run windows on a 600mhz x86. Who cares. Correct me if I'm wrong (I know you will) but isn't the x86 an incredably stupid processor for a game box. I mean it's great for web serving and running linux and all but i want to play games on my console and the x86 just doesn't do enough math to make it as compairable to the emotion engine that sony is using in the psx2. Use this for word processing and browsing the net but if you want games get a psx2 or a dreamcast. It's what all the console gamers will be useing and that's where the game devolopers will be i.e. Squaresoft and Capcom.
I don't care if the system has 32 GHz and 128 terabytes of ram and runs windows 2000, what games will it have? The only reason I bought a playstation was because it had some really cool games. Final fantasy is pretty much guaranteed to be developed for the playstation 2 for the next 3 years. Plus the playstation 2 will be able to play most of the playstation 1 games. That means out of the box I will be able to play all the games that convinced me to get a playstation in the first place. What does Microsoft have to offer? It has little to no console game history and I haven't heard that some of the major console gaming companies are planing to make games for the xbox. It looks like anyone who buys the $150 m$ system will have to wait till all their PC favorites are ported. Meanwhile everyone else will have their playstaion 2's with lots of cool old fashion fun console games. Microsoft doesn't have a chance with out games, even with 1 GHz processors and a hard drive to boot.

actually that would probably run a bit faster than a loop....

No, I don't think I will.
