He runs it on FAT, and disables all file security and so forth. In practical terms, this system is no better than Windows 98. For such purposes, load up Windows 98SE, and use Win98Lite to use the (much less resource-intensive) Win95 shell on top of Win98.
Just as secure, and you can have more functionality (e.g. sound!).
Of course, better yet, you can use Linux. I've got a 32MB laptop that runs Debian (with XFCE). A bit slow, but I can actually surf the web and so forth, and even play a game or two. And do it with actual security.
they changed the OS so that a very small portion of the Win32 resources loaded up at the 1GB memory address.
I don't doubt you, it sounds like something Microsoft would have done, but is there any independent confirmation of this, somewhere on the Web this is described in more detail? Maybe a Usenet post somewhere?
Apart from the commendable fact that you seem to write safer code than those SSH clueless developers
Go read the site. Mine is safer because it doesn't do nearly as much. SSH is complex because it has to be to do what it does. On the other hand, for many purposes SSH is overkill. At no point did I say that the authors of SSH are "clueless", though I'm tempted to say that about you at this point.
I'm surprised at SSH not having some, you know, way to restrict SSH access to a few IPs. Like a sshd_config directive called RhostsAuthentication.
But what if I'm travelling and don't even know what IP I'll be coming in from?
Also I can't believe OSs nowadays don't have a firewall or something to save you the work of doing something as l33t as that program clearly must be.
Your sarcasm-fu is impressive, but your research-fu is a bit weak. The closest thing to what my program does is port knocking, and that has reliability problems as you increase the security. Not that you, y'know, checked or anything.
Tell ya what, you point out a remotely exploitable hole in Ostiary, and then I'll bow down before you. I'm not going to hold my breath.
... I wrote a program that was utterly immune to buffer overflow and other attacks, and use that program to enable SSH for just the IP address I'm coming from. See the.sig for the details.
There's still one thing music can't yet do in video games: change styles in synchronization with the player's actions. Sure, music comes at important points, but it starts or stops then. You still can't have a dynamic score.
The Lithtech engine did this. It has a variety of musicial motifs which can be shifted depending on the current action. I understand it was used in NOLF & sequal; I know it was used to pretty good effect in Tron 2.0, 'cause I actually played that one. I'm sure other engines do that, too.
I read an article in a game AI programming book where they had to tweak that when creating NOLF; at first, AI entities (enemies, NPCs, etc.) could request the music to change intensity based on their own 'perception' of the situation. The problem was, if you startled a rabbit the score suddenly shifted to crisis mode! They had to put in some scaling so that the 'importance to the player' was taken into account.
Now, dynamically composing an original score is an AI-complete problem (imagine a virtual John Williams or Alan Silvestri:-> ), but mixing motifs to mirror the current game state has been done since MIDI days, as others have pointed out.
Sometimes I wonder what the MacOS would have looked like if those engineers would have known where it was going to go in the future, and knew all the modern techniques of programming? Alternatively you could ask, how would we design the Mac today if we limited ourselves to hardware available in 1984?
At least 256KB of RAM to start with, and limited pre-emptive multitasking; or at least they would have started out with Multifinder from the get-go. Actually, the Palm Pilots were very close to the original Mac in specs (68K processor, similar amounts of RAM), and the OS looked in many ways like the Mac OS, though it was running on top of a realtime multithreaded OS (AMX), so you can look there for ideas.
A few tweaks and it would have been quite expandable and extensible. See here for a discussion of how the model can be set up to do fairly useful multitasking.
The filesystem would definitely have started out with HFS (the Hierarchical File System) instead of MFS (which didn't really have directories, though it kinda faked it).
But really, for a first try they got a whole lot right.
...he was famous for being able to carry out prodigious calculations in his head. Two colleagues make a bet about how he'll solve a particular problem. There's a hard way and an easy way to solve it.
"So, Werner, two trains are heading toward each other. One is travelling at 60 kilometers per hour, and the other at 40 kph. A bird starts at one train, flies to the other at 120kph, and as soon as it reaches the other train it instantly reverses course back to the original train. It continues to do this until the trains meet. If the trains start out 100 kilometers apart, what is the total distance covered by the bird?"
(answer in reply to this comment)
Hesenberg instantly replies, "120 kilometers!"
"Drat!" says the questioner, "I bet you'd solve it the hard way!"
At my last job a guy told me the story of a programmer forced to implement some stupid feature due to a customer demand. He made the behavior dependent on a conditional variable named "CustomerIsAnIdiot".
It's very rare that you see anyone in the movie industry taking the time to make their technology realistic.
Ironically, the few that do try tend to do very well. E.g. 2001, the Abyss (the human tech, anyway). Of course, that might be putting the cart before the horse. Perhaps getting the tech right is just a sign of a good filmmaker.
It's just a generic webcam plus a microphone. There's even a beta Linux driver you can Google for. The magic is in the software, and even that's not too amazing, it's just edge detection and such. But it is fun, and a great way to get kids to exercise.:->
If this were the case, then the PS2 would have been subject to countless hacks
The Linux on PS/2 had some serious limitations. It didn't run on the raw hardware, it ran on a bit of an abstraction layer, that enforced some limitations, like no DVD playing, as I understand it. I saw a presentation by the one of the guys who made the compute cluster out of PS2s and he said that the access checks in that abstraction layer seriously slowed down certain operations.
Making games for PS3 Linux will probably have to deal with limitations (like the screen resolution limits on the PSP - it won't let just any program use the full native screen resolution, just ones approved by Sony) and won't be a good commercial bet since probably most people won't have a hard drive hooked up to their PS3...
All the game's features should be unlocked from the start, so that there's no learning curve and no incentive to play further in the game. In fact, all the levels should be unlocked and selectable from the start. In fact there should be a neat synopsis of the game on a single sheet of A4 in the packaging so that I don't have to play the game and can get straight on to bitching about it on the interweb.
Sarcasm aside, how about throwing a bone to those of us who don't have time to level grind to get to the good stuff? I rented a frickin' Hot Wheels racing game for my five year old, and neither one of us got more than one car unlocked before it was time to return it. Either offer a way to cheat (hey, you don't have to use it, and feel free to deride me for using it, and I'll even pretend to care) or else scale the way things are unlocked by the difficulty level.
You can make things secure if you design them properly, but you do pay a price in convenience. If you can find a remotely-exploitable hole in my Ostiary program, I'd be very impressed...
In these days of camera phones in locker rooms, and hidden bathroom cams and the like, are you positive there aren't any unauthorized nude picures of you out there?
Set on a ship where the speed of light is 10 meters per second. It's easy to exceed the speed of sound, and a good run will shift colors and cause objects to bend. Everything you see is at least slightly in the past.
An FPS would be very interesting (and educational, even!) but doing multiplayer would be extremely hard if you wanted to model time dilation too...
Sixth knowing that it will work. Other then putting Linux on a bunch of hardware designed to run on windows and taking you chances and replacing anything that may not be compatible. Just put all the old stuff aside and go with new hardware.
That's cute. Instead of replacing only what doesn't work, replace everything! This is a plus?:->
Seriously, there are some good points there. But when it came down to putting my parents on a Mac or on Linux, well, I chose Ubuntu. Works, they're already on Firefox & Thunderbird so there's no 'migration' there, and for the funky media formats I can use the actual win32 codecs and be done with it.
Plus, they can run actual Windows for games, if it comes to that.
The interface is clean and doesn't get in the way like windows or most Linux WMs
I've had no complaints from my parents about the UI so far. It's at least no worse than Windows.
They had good actors for the in-game video and audio for the first edition. Then they released the "Gold Edition" and they'd redone the voice and video work with extremely crappy actors. I later found out it was the developers of the game indulging their vanity! Fortunately I was able to use the old videos in the new version, saved the game for me.
of course, 10^-18 is a number very similar to 10^60 or even 10^-60.
The same article says that squeezing a proton through needs ~10^30. An electron is three orders of magnitude smaller, so now we're at 10^27. Photons can have even less energy. Still a ways to go, but in the 1940's it would have been considered utterly impossible to get silicon as pure as we have now, by nearly as many orders of magnitude.
Maybe we won't ever be able to squeeze a human through. You're saying you can't see any use for a 'time modem'?
The silicon in the average computer chip is absurdly pure - we're talking 10^-18 impurities in some cases. For comparison, I remember reading that if you covered the entire North American continent with an apple orchard of the same purity, you'd have three non-apple trees.
This would never, ever happen naturally, but nowadays most people have a silicon chip strapped to their wrist. See if you can count how many are within five feet of you.
If wormholes are possible at all, then we'll just have to build a control system to stabilize them, that's all.
"you" are just a very complex pattern in our quantum reality, constantly being replaced
Sure, I know that consciousness is a process, not an item. On the other hand, so is, say, a tornado. Is a simulation of a tornado in a computer the same thing as a physical tornado? If you measure a tornado down to the individual gas molecules and simulate that on the computer, can you say that the tornado 'lives on'?

Now those were funny movies. No series is complete without a giant death beam somewhere.

There's a good rundown of the situation here. What's funny is that Microsoft actually paid for BSD code.
