He actually mentions that he likes the eraserhead (trackpoint) so a Thinkpad without the trackpad is probably what he wants. I find it hard to believe that he didn't know about this.
Also, if the trackpoint annoys you (I assume the person asking uses an external mouse?) just pop off the eraserhead. I don't know how to get rid of the buttons, but if that is a problem the the poster is just crazy. I already think he is crazy since turning the trackpad off is easy, and I fail to see how its presence is "offensive". To each their own I suppose.
Try this. If you use the trackpoint your hand barely moves from the typing position. At the same time it gives you the option of a trackpad if you find that easier. Oh, it has a total of five buttons.
This is great advice. The parent has actually written a pretty fun game and knows what he is talking about.
Having written some simple games myself, I have found it very helpful to just get something very simple working first. Then I add things step by step. I have seen too many projects get bogged down in simply creating large amounts of artwork and no coding ever happens.
I start with just being able to draw something on the screen and work up to an overly complex AI, but I added things one at a time rather than trying to do it all at once.
Finally, I agree that 3d games are a bad choice for a first time project like this. 3d is exponentially harder to do right. Start with something that wouldn't look out of place in an arcade in 1982.
This isn't reverse engineering. This is hacking the system to get an output method and then dumping the bootloader, not reverse engineering the bootloader. To reverse engineer it would involve figuring out what must be in it indirectly. That doesn't take away from the coolness of the hack though.
I have it on very good authority that the reason that iPod hasn't support ogg-vorbis is not a technical one. It is that Apple is afraid that the owners of the MP3 patents might think that ogg-vorbis infringes on some of their IP. Apple doesn't want to become a test case, regardless of the merits of such a claim. The iPod is selling ok without the ogg-vorbis support.
Since I am dumb enough to post to/. with my real name I am not going to say how I know this.
So the iPod is capable of it, and now hackers will be able to support it. Apple could but won't.
Those numbers are for a chip that is at least four years old. I just happen to have them handy.
There are a few considerations here that you are overlooking. One is that PK really isn't needed here. A 3DES operation is just fine for a mutual athentication and considerably faster.
Also when using a contactless chip, the chip can authenticate as soon as it is in range without waiting for a button press. This means that by the time you are reaching for the handle the operation has already occurred.
Finally, we aren't restricted to smart card chips or form factors here. I only brought them up becasue another poster claimed that doing 3DES was too slow on an inexpensive processor.
Well Phil, that depends on what you mean by "quickly". Here are the times in milliseconds for various public key operations on a popular, inexpensive smart card running Java:
1024 bit CRT public key operation (F4): 33
1024 bit CRT private key operation: 417
Generate 1024bit CRT key: ~3800
Generate 2048bit CRT key: ~62000
Key generation is usually done only once, at issuance. Times are approximate since it isn't a fixed process, sometimes it takes longer to create the key.
There are plenty of smart cards that can be powered by either the contacts or through RF induction. I have one right here. RF smart cards can do everything a contact card can do. In fact they communicate much faster. Yes I know that is counter-intuitive.
To put it bluntly, you don't know what you are talking about.
I work in the smart card industry. You can buy smart card chips that do 3DES and 2048 bit RSA for less than a dollar. You can buy a complete contactless card (what idiots here would call RFID) that has a Java operating system, does 3DES in less that 70 milliseconds and does RSA with on card key generation for about $6, and considerably less than that in volume. These chips have specialized hardware to speed and secure the crypto operations, but any 8 bit processor with some storage can do 3DES in a reasonable amount of time.
As for AES, it was designed to be able to be run on smart cards and there are implementations of it.
In short, strong crypto on a keychain is feasible. I have half a dozen keyfobs on my desk right now that do it. The reason for the 30 bit key probably has more to do with export regulations involving the US and Japan than any technological problem.
What does a battery have to do with encryption? Smart cards (both contact and contactless) have no battery yet can do 3DES and 2048 bit RSA. The battery can increase the range of the device, but it doesn't improve the encryption at all.
Speaking of IBM, has the thinkpad design changed drastically at all over the past TEN years? Maybe a little lighter, but I would say that laptop is much longer in the tooth.
I have had five IBM laptops over the past seven years for work. A 530 (not sure about the number on one), 770, 600, T21, and T40. Each one has had significant improvements over the previous ones, though I will admit that they were all black. IBM's product line is certainly different from Apple's, and it evolves more constantly. In contrast Apple makes occasional drastic changes. Saying that Thinkpads are "long in the tooth" is indicative of your lack of knowledge rather than any fault of the Thinkpad line. In case you take this as an anti-Apple rant, I ordered a Mac mini ten days ago.
Have you seen the whole new serires? It is comparable to 24, without the "try to find a way to waste time this hour" thing going on. The original had some continuity, but not nearly to the same degree. Someone in this thread made a joke about the casino planet. To quote the Simpsons, "It's funny beacause it's true!" The second hour of the two hour pilot in the original involved the casino planet. Look at what happened in the first and second episodes after the miniseries in the new version and compare. I love the original as much as the next person, but this new one is great.
I don't want to have to sort through a stack of "super deals" that are just there to lure me to a site which has a warning that I shouldn't ever buy generic ram.

You are forgetting the IIgs.

Michael using his power as an editor to troll! And I thought he had grown out of that.
I would love to tell everyone how I know this. It comes from the head of the iPod division. That's all I'll say.
Having written some simple games myself, I have found it very helpful to just get something very simple working first. Then I add things step by step. I have seen too many projects get bogged down in simply creating large amounts of artwork and no coding ever happens.
As a poor example of this method, I have written a pac man game tutorial. It is one the web at http://www.angelfire.com/games4/anirak/tutorial/da y0/.

then this Next box mentioned above already has revolutionized gaming, years ago.
Didn't id write the code of some of the early FPS games (Wolf3D or Doom) on Next systems?

The Mac mini also lacks the gig ethernet. It is only 10/100.
It isn't what I meant, it wasn't my sig. In any case, I am below the gum stuck to the bottom of your shoe.

that is exactly what I am talking about. Will it work with a Mac mini? I doubt it given that it says right there that it works with almost nothing.
You are correct. I meant "median" and wrote "mean". I am obviously below it, whatever it is.
I don't want to have to sort through a stack of "super deals" that are just there to lure me to a site which has a warning that I shouldn't ever buy generic ram.
I have an email in to support, I haven't received a reply.
Where is your ram from? I am waiting for my mini to arrive and I want to upgrade to a gig. I can't find a gig stick of PC2700 for $125.
