  1. I don't - I design these and similar items: http://www.metacafe.com/watch/62248/guided_artillery_projectile/ for a small research group in wine country. Now, my previous career before Apple, I actually was an engineer designing breweries which were fabricated in Sonoma, but that's a whole 'nuther story.
  2. Don't hate me yet. San Jose real estate market going through melt-down. :-)
  3. Worked in Apple's PD group for seven years. Left July 1 after finishing the Iphone. Now, I'm an engineer up in Sonoma wine country. Once my house in SJ sells, I'll be a relaxed man. :-)
  4. (2x post)
  5. The problem isn't matching the exterior but tying the thermal management of an upgrade card into the internal airflow for cooling. You either: 1) leave an over-sized thermal management (better-gpu= more power)system in the enclosure and hope that your thermal contact between the slide-in gpu (sans heatsink) and the thermal management system doesn't leave your gpu temperature too high 2) allow the system to account for the on-card thermal management system (say goodbye to thin systems and hello to a much larger blower to overcome additional airflow impedance and competing flow directions). The current airflow is balanced for the finstacks/impedances that it is designed for. To try and account for all market-potential finstack impedances/designs on one conduit section requires at least one airflow sensor added (and calibrated) into each unit and increasing the blower height (bad for thin enclosure). TBH, it probably couldn't be done without 2 sensors (one for each leg of the conduit and good deal of smu code to interpret the output of the sesnsors) and still requires increasing the size and noise of the existing blower. 3) disconnect the gpu thermal management system off from the cpu thermal management system (currently joined by heatpipes and common finstack). Assuming that the customer doesn't make a mistake in thermally attaching the gpu card to the Apple-designed gpu thermal-management system and that none of the baffles are dislodged/damaged by sliding the thermal control system into/out of the conduit, you still have added in an impedance from the additional GPU only cooling finstack. The problem is compounded by the historically bad power-management code shipped by graphics companies especially with new products. The graphics companies get kudoes for performance so their code keeps the gpu spun up almost all the time (and often ignores system calls to reduce power). When the blower to cool the extra power is sitting 18" in front of your face, this may not be exactly what you want in a customer experience. Please note that this is a personal response and in no way an official statement by Apple, Inc., or its Product Design group.
  6. ATI card is best performer from internal testing on various games.
  7. Did you install playgate_206.bin from downloads.wwiionline.com? On the main page, click the button to take you to the downloads page. Then about midway down the left column is a link to a ftp site ftp://downloads.wwiionline.com where you can find it. I haven't ever seen that error myself so I am guessing a bit.
  8. There are rumors of upgraded bootcamp with better video drivers being tested at Apple.
  9. Perhaps I am not making myself clear. In what you are calling the "Game Loop" does that include the Physics Engine (which calculates all the motion/acceleration of objects in the game)? Wouldn't a physics engine update of 100 times per second versus 1 per second result in wildly different physical outcomes? An example: A bullet fired from a gun at time 0... 100 updates per second system - the bullet's velocity is recalculated at 10msec intervals so drag is applied correctly, steadily increasing deceleration. 1 update per second system - the bullet's speed is re-calculated after 1 full second during which the bullet moves at full muzzle velocity for the entire second. The system would then apply a huge amount of deceleration for the next second. The first bullet might have travelled 500m while the second one might have travelled 750m.
  10. So your Game Loop diagram would imply that the game's physics engine updates differently based on your FPS. Is this true?
  11. Tautu: Be careful with this. The ATI chips came in hot (i.e. burning more power than they should) which is why they were down-clocked until ATI got better control on power. The GPU also ignores calls to lower it's power-consumption when the CPU needs more power. Running with the gpu wide-open increases the chances that too much power (from both CPU and GPU) will go into the thermal solution, causing local dry-out of the heatpipe. The CPU has over-temperature protection so nothing too bad should happen to it; however, the GPU does not. If the dry-out occurs at the GPU, you could be looking at a dead-unit.
  12. Yeah, my first inclination was to respond with "azz-ugly shoes and a chick that's twitching the ol' dyke radar", but thought that it might be a lil' harsh and potentially actionable with HR at my company.
  13. Works fine for my Safari Version 2.0.3 (417.9.3). Shows some azz-ugly shoes.
  14. Voyager2 and Ivertti: Seriously, thank you guys for being customers and for being understanding when things don't come out exactly as desired in mass-production. The company usually does a good job of making it right for the customer when something unforeseen happens. Innovation and perfection have never played particularly well together. Voyager2, I'll trade you in-depth walk-throughs of the design for helicopter flying lessons. I do volunteer work for emergency response when I am in CA, and I have to admit, it's a huge rush to ride the ANG's Blackhawks to be dropped off to a remote spot in the mountains. We all race to respond to incidents in the Wilderness areas because "the early bird gets the worm" as it were. The latecomers usually have to hike or 4x4 to their (closer) assignments. ;-) Xgidds: I am not a bad guy, and in re-reading I regret some of the more direct statements towards you. However, you lashed out pretty hard at me and people I work with every day.
  15. ahwulf: any virus protection available yet for Windows on Intel-MAcs?
  16. I have always used Safari for logging in without issue. Is there particular testing that would be helpful?
  17. Keep me in mind for testing. I have the 17" MacBook Pro. Oh, I can answer your general mechanical questions about the portables via PM- I am one of the engineers who designed the MacBook and the MacBook Pro (still unsure about the name-change). Software, driver, and applications questions are likely to be met with a blank stare.
  18. 1) What nation found itself in the curious position of being at war with the UK and at peace with the US during the period 1942-1945? 2) What unusual circumstance or action occurred which brought about this situation? Answer in 48 hours if no one responds correctly. Good luck.
  19. Seri Thai was one part of it. Apparently, one of the other politicians (Pridi) went into hiding in Thailand so that his signature was forged on the document declaring war. He then went on to form a resistance movement within Thailand that eventually linked up with the external movements (Seri Thai in the US and a weaker one in UK. I forget the UK leader's name but he was less successful because he was perceived as a Royalist seeking to return the absolute monarchy that they had thrown off a few years before). The whole episode is confusing, but it seems like a lot of collusion on the part of the Thai politicoes to comply with Japan's demands to the letter of the law while executing them so poorly that their actual intent was clear to the Allies. They must have done something right because the world community had no objection when the "dictator" responsible for leading Thailand during the war was voted back to power in 1947.
  20. I'll go ahead and close it out. The Thai ambassador to the US refused to deliver the war declaration to the US Secretary of State, Cordell Hull. He told Hull what was in his pocket and said he felt it did not represent the desire of the Thai people, so he instead resigned his position and volunteered to help the US to create a Thai resistance movement called Seri Thai.
  21. Well then I'll give it to you although it ceased being Siam in 1937. Know how it came about?
  22. If true, not the one I am looking for.
  23. Voyager2, the internal numbers are between 2x-4x better for the new hardware. Running WW2OL is still problematic on the pre-prod hardware as the software is still maturing so I can't do a direct compare yet. I will be given a personal unit within a week of the beginning of production. At that point, I can do a direct compare to my current Powerbook and post numbers. The only concern that I might have is whether any part of WW2OL would hit the emulators which will bork performance. PM me at intervals to keep this testing in my mind... as you might imagine, I have a fair few things keeping me busy until we get into production. :-) They really are that great. I would buy one if I wasn't addicted to the bigger screen size. The marketing commit lowballs to guaranteed performance of 1.83GHz. These babies with run-of-the-mill chips are carrying 2.17GHz with ease in normal room temps. Unless you live in Arizona, you'll be exceeding specs. (please note that the previous comments are my own and do not represent any official company guarantee of performance)
