  1. well if you want the whole story on Slashback: Grids, Netscape, AMD · · Score: 5, Informative

    you are right; game consoles do use RDRAM. But in the end, RDRAM is not killed because it's bad technology, but because othere stuff.

    first on the tech. (REALLY quick brief)

    1) RDRAM has a faster interface (duh)
    2) and it has a much more narrow bus
    3) but to make chips drive at such a high frequency ON THE CIRCUIT BOARD, the bus interface for RDRAM is totally wacky

    explanation: RDRAM is serially connected, *kinda* like... SCSI, or COAX ethernet back in the days. and it's heavily terminated. and because the signal goes so damn fast (remember, circuit board made of FR4 here - not cache->CPU interconnects), the routing of the signal traces, while sparse (something they tout - and it's true, DDR has like 2-4 time the wire density as RDRAM on the board), has very small tolerance for length difference. furthermore because the high speed, the chips must have a very strict output impedance (which is why mem-makers got shitty yields at the beginning and the RDRAM price were so high).

    performance wise / practically speaking, since it's the signal routing / RIMM detection and delay adjustment (remember no trace length differences etc) that's difficult and causes trouble - in game consoles where you will never add memory, RDRAM is actually better (easier to work with / better performance - better perf because you don't incur additional delays in the trace by adding more modules, everything is fixed). Same time on PCs, when you do it right, RDRAM still offers better bandwidth than DDR; DDR-2 i am not so sure, but that won't be in massive production for a while so don't wait for it yet. depending on architecture (P4 is, have to say, on the side of "optimized for RDRAM"), you would get better performance out of RDRAM for a little while longer.

    now the non-tech side:

    RAMBUS charges royalty. 2% i think? now - memory business is not high-margin business (or else there won't be only like 4-5 memory makers left!), so when 2% is actually like 40% from the margin - if you can do away with RAMBUS (even at a performance hit), it would enable you to survive, or make more money - depending on the company.

    so... the moral of the story? RDRAM is not bad technology (i.e. has its uses - like in consoles), but it's not GREAT technology, and certainly not good enough to warrent the margin cut and the headaches in engineering (output impedence - and these days they are going to 32/64 bit so the sparse signal lines is less and less of a advertisable benefit). But I expect that it will maintain it's little niche and won't just die off suddenly one day. i mean, heck - even if they only supplied for the game consoles, (especially with the large chunck of change intel gave to RAMBUS) they can survive for quite a while. RAMBUS as a company I think will eventually fail if they continue this path of IP-only, though - for other reasons. but this is getting long already.

  2. an older version on Motorcyclists To Get Wearable Airbags · · Score: 1

    They used to have one (actually still do, methinks) airbag where it inflates via a string attached to your bike.

    In the other words, when you are flung off, the string pulls, and you puff up like Kirby before hitting a tree / pavement / alien mothership.

    Only, of course, people would forget to detach the string before getting off the bike, so you'd stand up, wave "hi" to the hot chick who's checking out your ride, and dismount to greet her - and all the sudder "pop - BOOM - pffffff" and you will be the laughingstock for the entire hemisphere.

    anyway - the airbag vest thingy aforementioned was supposed to be re-fillable / re-packable / re-chargable / whatever, because the makers forsee (or maybe had personal experience during trial stages?) this kind of stuff, though.

  3. why would you do this for emergency power backup. on Fuel Cell Powered Backup System · · Score: 2, Interesting

    from their "benefits" page:

    > Quiet Very low noise operation

    so is a battery backup - Okay maybe it's a little more noisy but I have been next to huge APCs and they are completely drowned out by server hum and cannot be heard anyhow. My personal UPS does not make a single sound.

    > Air Pollution-Free Operation By-products are heat and water vapor Renewable Energy Powered by two of the most abundant elements -- hydrogen and oxygen -- in the universe

    No arguing, but soooo? (more later)

    > Clean Energy Perfect sine wave electricity to protect sensitive electronics

    okay, so is a UPS, again.

    > Indoor Use No carbon monoxide emissions

    I am tired of typing "okay so is UPS"

    > Non-Stop Power Continuous electricity generated as long as hydrogen is supplied.

    I should hope!

    now onto the blab:

    Yes yes I know for a lot of trouble, this makes a good portable generator (maybe). But they are saying this will be a good power-backup too? my ass.

    1) UPS has battery that runs out. This has hydrogen that runs out. same deal.

    2) UPS can be re-charged when the power comes back - this I have to buy more hydrogen tube thingys

    3) I am guessing that this uses the ROOM oxygen? like, the one we need to breath with?

    4) where exactly is the water (byproduct) going? I remember that fuel cells has a high temperature - I assume vapor? as in bumping up the humidity to some insane levels in the server room? Even if it does not - I would think there need to be new pipework / whatever to carry away the condensation.

    Let's not forget that it probabbly cost a bundle starting off / maintain too.

    Now with that vented - it would be pretty cool to get one to replace one of those noisy generators for a motor-home or something - but THEN, it's designed for indoor use (i think)? wtf? and i have to either carry AirGen cylinders (low pressure) (read: does not last long), or hydrogen cylinders (read: really dangerous) around instead of just getting some gasoline at the station?

    erm... I will stick with a portable generator (for power generation) and UPS (for backup) thank you.

  4. hmm? u check prices recently? on GNOME 2 to Replace CDE As Solaris Default DE · · Score: 5, Informative

    I think a brand spanking new SunBlade can be had for like 999 dollars. I mean, not Walmart-Lindows-cheap, but I wouldn't call that expensive.

    Especially considering that I think you can attach a "PC on a PCI card" and run a full blown x86 OS side-by-side (for what I don't know, maybe apps dev?).

    on the other hand, I don't know what to make of this constant change of GUIs. many people loathed it when Sun went with CDE from OpenWin, so they had to support both, and now switching to GNOME when finally CDE is getting reasonabbly stable and whatever (and I am actually pretty sure there are a handful of CDE zealots out there that's very vocal) so they will probabbly need to support all three from now on.

    I mean... while good news and all, just another facet of the sun indecision "Sol9 for x86, not for x86, cost $$, maybe not, go with one GUI, but wait lets change it over later." AFAIK Java has not suffered too much amid these indecisions and the specs havn't swayed that much (somebody correct me if I am bs-ing), which is thankful for.

    Of course, I can give you what I personally like in SciFi - imaginative worlds are always welcome (well described, mind you), and intellectually stimulating is also another plus (social / psychological / whatever problems that arise from these new and imaginative circumstances); beyond that, here and there some action / romance / whatever to help push the story along so I actually look forward to continue reading.

  8. Re:strange people on 24 Hours Of Beethoven's 9th Symphony · · Score: 4, Informative

    I know "Empire" because I took a philosophy of art class.

    Now, I am probabbly getting a lot of this wrong and my professor will smack me for getting them wrong, but as far as I remembered, one of the mojor reasons why it was so "genius" is because it explored the medium of film and contrasted it to the ideas of stillness.

    The idea is that on a static medium (painting / photography), you obviously cannot show movement, as even the best painting is only the capture of a moment (lets not get into Van Gough and the funny square stuff for a second);

    Similarly, a moving medium like film can capture motion, but in turn, it REALLY captures something static in a much more "complete" sense than, say, a painting can - case in point, you can see the empire state building, unmoving amongst the birds (there is this famous scene when a seagull flew by), clouds, etc. This contrast of moving (the environment) and the still (the building) is only captureable, and experssed, on film. In turn, the stillness of the building is understood in a way that is unexpressable on a photograph, a painting, or whatever.

    Of course, maybe there are some obscure purpose to this stretching of the symphony too? I really don't know - one thing the class taught me was that art is wayyyy over my head. :-)

    What laws were broken by selling stuff to China? the companies are doing what they are there to do - to make a buck; while the moral grounds on which these actions stand may be questionable, so far the story does not provide any evidence whatsoever that these companies are breaking US or Chinese laws.

    At the same time, I just want to repeat Lenin's lil phrase "A capitalist will sell the ropes for the hanging of another capitalist".

    To a great (and depressing) extent, this is very true. Corporations are not doing things because they are The Right Thing (tm), but because it makes more profits. But then the reason for corporations to exist is always to make profits, so what the hell you guys expect? look at all the company motto and "visionary statement", around and around it circles the "stockholders." Not the hungry kids in wherever, not the mother earth, and sure as heck not the principles of all that's good and right.

    So to have a system like this, you gotta live with the consequences, which is that sometimes companies will do morally questionable things, and sometimes illegal things. the illegal we can bust them - but the morally questionable, well...

They say it's "limited time only" or some such bs, but that's what it is, bs.

    Then again, companies are not showing up to trade shows as much as they used to be, or are renting a smaller booth, becomming a smaller sponsor (i.e. from platinum level down to gold level) or not sponsoring at all. (Sponsoring is when you pay them big bux and they put your logo on the T-shirt / booklets / whatever) - the level of sponsorship determines the size of you logo, where it appears, etc.

    An example (not Comdex) on the low-attendence is this year's ITC (International Test Conference), which is one of the most important conference / tradeshow / whatever for the ATE (automated test equipment) manufactures. Teradyne, Credense, NP Test (read: Schlumberger) all decided to not show up at ALL; no booth, no seminar, no salesperson, nothing. These are some of the biggest names in the industry. I think the only two big-names that did show was Advantest and Agilent (I'm not sure about Agilent, actually).

    As for real paying visitors, they are dropping even more than the companies - Other conferences actually have REAL SEMINARS where people might pay to see, but Comdex, IIRC, never had anything informational.

    Besides, the stupid show went downhill way before the dotcom bubble bursted. Back in 99/00 (i can't remember clearly), they had 1/3 of the floor filled with resellers / distributors that sell cases and powersupplies and such. not even nearly related to "technologically innovative." No new technology, no new information, just a big organized garage sell.
