  1. exactly the kind of thing I'm thinking....100 million lines of code is some serious shit. As for the OBDII thing, that's just a diagnostics port accessing a memory map. That kind of system architecture is used everywhere (like in the last board I just made, but in FPGA form) and the code it requires is minimal at best. Trust me, I've made one from scratch in out of VHDL, and it ain't a very big deal. Having the framework already made in a CPU is even less impressive. Hell, the arbitration is the hardest part, and that's cake since there's only one port. Kind of hard to make a big deal out of a memory access arbiter that only has one port...it's like trying to ref a game that only has one team. Let's be honest, any of the other digital EE's here will tell you that a car is (in my rough estimation) almost entirely a series of control systems. Fuel maps? They're just multi-dimensional LUT-based control algorithms. Drive-by-wire? Simple negative feedback (and maybe feed-forward) control loops. The whole thing is pretty underwhelming, and the processors they use are never leading-edge. Shit, most of these systems' loop responses are so painfully slow anyway (because they interact with mechanical systems that have crazy slow loop responses compared to clock speeds), so there's really no need for super-high-end processors or high-bandwidth comm systems. Sure, there are a lot of controls, but this stuff really shouldn't be that hard. Or maybe the FPGA world has jaded me, and turned me into some kind of digital snob. Even though I still think drive-by-wire systems are cool in theory and scary in practice....
  2. imaginary rep for using "zerg rush" in context....
  3. i'd be curious what they say. If that's really the case, I'll believe it, but I'd just be blown away. It's amazing just how many lines of code 100 million is. We operate our entire industrial print systems from top to bottom with under a million, i'd bet. And i'll bet you that system does a hell of a lot more computing than a corolla does...
  4. Am I the only one that thinks that there's no way in the physical universe we occupy, that a Toyota has 100 million lines of code running it's combined systems? I was on a team that made the brains for the spectrum analyzers for new generation info collections systems in planes like the awacs - that system had 43 FPGAs and took up a space the size of half an entire hockey bag and that still probably only fit about 5-10 million lines of code. I may very well be wrong, but that number just seems way too large to me...

    The Bloom Box

    interesting... I'm clearly out of my element here because the idea of a room-temperature phase change with a simple solid catalyst is too far beyond me. I get the idea of introducing a gas with another gas in the presence of a catalyst and getting a different gas, but I thought the appeal was that you would use any hydrocarbon-based product (ethanol, methanol, etc) and get the same result. But then you're putting a room-temp liquid across a solid in the presence of a gas and getting a gas back out with no liquid or solid byproduct. That's the part of the science that's beyond my level of understanding. If that's true, that's some impressive shit...

    I did just peruse over the article, so maybe I missed it, but what is the byproduct of this system? You put natural gas in, you put air in, what comes out? Are we left with some useless sludge, or is the byproduct a useful material? If we just end up pumping millions of barrels a day of petroleum-based products into a global system of these things, are we just going to end up with millions of barrels a day of useless waste sludge when it comes out?
  7. Very nice guys, we really appreciate it. I broke my trackday cherry with STT at Gingerman and I loved the people and the track. I'm absolutely in for this.
  8. M3's alone would put Germans at top of my list (if it weren't for that whole 'nazi' thing a while back) for engineering. I saw an Alpina Z8 once in a showroom in Cinci when I was a teenager, and I was hooked after that. Seen a few Dinan and Hamann builds that'll make you melt too. Love those cars. And the carbon fiber front splitter looks tits on that M3...

    Shaun White

    E, let me correct you - that was not just some chick who finished on one leg. That, sir, is Lindsey Vonn...
  10. good to hear Matt, and I'll be seeing more of you in the summer since I work at Kodak, right behind your new building. I'll be expecting to hear that 636 come closing time on weekdays this summer....
  11. my brother-in-law's cousin's second baby's daddy had a kid with another chick that got eaten by the Obamas. they said it was Bush's fault.... (insert more fear here)
  12. I've loved bikes forever, but never really had my balls drop until my first co-op job, when my boss bought a new '03 SV650S, and I rode it in the parking lot. I bought it from him 6 months later and spent the next 3 years learning it and tinkering around. After a while it got to look pretty nice and I was really loving it. Then I let a friend drive it in a parking lot and he wrecked the shit out of it.... After he bought it, I got my CBR, because I wanted to impress the 14-year-olds that hang out at bike night. I just power-wheelie in like a boss and let 'em know what's up, 'cuz bitches love CBRs.... But seriously, look at those strips in that pic, even My Little Pony would tell me to put some back into it. Now I have a GSXR for the track because I hear it's what all the cool kids do, and I'll do anything to be cool. I guess that makes me a sheep, but I hear that's pretty cool around here too....
  13. As long as something cool happens when we type in the Konami Code, then I'm all set....
  14. Unfortunately, Carie told him he should try to 'upgrade' a few other things first.
  15. so, just hypothetically, this could make my keyboard more resistant to "stains"? just hypothetically...
  16. I have this exact solution. I used a length of 2"x12" and it's plenty of width to load it into a cargo van from a level surface, then I just toss the thing in the back with the bike. Super cheap, super easy. I was surprised how little it bent when the bike went up it. A lot sturdier than I thought it would be. Just push the little bastard up and you're ready to go....
  17. "Jesus Archer! what if I'd been real KGB?" "I imagine you'd be trying to suck a promotion out of some Russian guy's cock."
  18. Still my favorite little gem from the pilot (by the way, it took me a bit to figure it out, but I arrived at the joke eventually): "johnny bench called" and of course, "Oh god, with the curry again. This shirt smells likes Indira Gandhi's thong."
  19. the yota one is pure hilarity....
