The heatsink on my 2x1.25G4 mounts very simply - the face is perfectly flat, you lightly grease the dies and lay the sink down on top, then tighten the 6 screws that hold it in place. No clips, no excess pressure, no nubbies, just some screws. How are they on the G5s?
Noo, I never could have figured THAT one out, especially since people generally stop taking me seriously when they find out I use a Mac, and dismiss me as one of "those crazies". Zealots of *any* breed are a bad thing (which is why I can't figure out why so many people here are proudly admitting to be linux zealots); do you really want people 5 years down the road to call you one of "those linux nuts?"
Terrorists..well, not yet. I could concievably see a star-crossed young and naive OSS nut cracking MS's network and erasing/stealing/tweaking/releasing Windows code though - I've hung out with enough radical vegan eco-crunchies to know that there's a fine line between zealotry and terrorism (Earth First!/ALF/ELF anybody?) that can be blurry, if you're commited enough to your cause.
It eliminates the all those other variables, leaving only the drives themselves to affect the speed. Of course, whether or not reading a mutt mail folder really depends on drive speed is up to you.
Well, really. I'm surprised Ars didn't at least mention, if you don't want windows, you can get a God Box off-the-shelf from apple. PCI-X, GHz FSB, SATA, dual procs in the same class (Ars uses 2x3GHz Xeons), dual flatpanels (and nicer, too:P), all the same bells and whistles PLUS 64-bit goodness...prebuilt for less (i could be wrong, i didn't spec them both out to check..)
It seems all Intel has done since the PII is add more pipeline stages and crank up the speed. Of course, that's all it takes to sell the public..."Well my p4 has 2GHz, so it must be better than your mac, it only has 1.25GHz!" (actual quote - i HATE when non-geeks say a computer 'has' so and so many hertz...oh, and the kid shut up when i said i had two of them, so mine is clearly superior)
Then in 4 or 5 years, I could see them taking off - if comparbly-spec'd Apple boxes were available at every price point over $700, there'd be a huge flow of people like you who would, at their next computer purchase, decide to switch boats. Why buy a $900 crap Dell when you can get a decent $900 iMac with OS X? Unless you're a raging x86 fanboy, the hardware underneath the OS shouldn't matter.
...since they'd have to spec the former 2x2GHz G5s with 2x3.2GHz Xeons. Might even make the price go up, Xeon 3.2s are around $950 on PriceWatch, dunno what they are in lots of 1000 though. Damn...that's almost 2/3 the price of a new 2x2 G5, for just the processors...wow.
It began as PReP at IBM, the morphed to CHRP when other vendors signed on, then finally got knifed. Apparently, IBM and Moto killed CHRP not becuae of OS/2 PPCs snafus, but because Apple would not license MacOS.
Here's a list of PReP/CHIRP systems that shipped:
Motorola
* PowerStack series
* MVME
* MTX
IBM
* RS/6000 40P 43P
* PowerSeries830
* ThikPad850
Really, go look at the x86 boxes Apple benchmarks against, and go price one out yourself. And no cheating with el-crapo parts, Apple uses at least semi-quality hardware.
It seems they needed Apple's business more than they thought - I haven't seen many uses for a G4 outside of a proper computer, it's much to power-hungry to be embedded, but far to weak to be a real desktop competitor anymore. I wouldn't be surprised if Moto quietly knifed the line when Apple goes entirely to G5s.
*sighs* well of COURSE an ICE isn't an ideal Carnot engine; I'm not trying to cover all the bases, just present a gross oversimplification, since I'm assuming you haven't suffered through a junior-level semester of thermodynamics. I haven't been misled by anything. I came up with the entire argument myself, with a little help from my text; I added the website as an afterthought to more clearly explain what I was saying. Please give me proof that a Carnot engine is the ideal way to extract electrical energy from hydrogen - 'The answer, btw, is no" is NOT sufficient. "Although Carnot engines are inherently inefficent and wasteful, they have proven to be the most useful realistic design due to the relative ease of construction and operation as opposed to more ideal solutions." - quote from Atkins. I suppose the truly ideal solution would be to somehow reduce the hydrogen to pure energy, but failing that, some sort of direct use of electrochemistry would seem to be the best way. I'm curious..what PChem text did you use for your thermo class? Not Atkins, otherwise we wouldn't be having this discussion.
ORBITAL solar cells - I don't believe in the usefulness of Earthbound solar panels; they're far too subject to the whims of nature (i.e. clouds). Plus, you get a *lot* more UV radiation in space, which is ideal for solar power - it's still able to cause the photoelectric effect in a wide range of material, but is MUCH more energetic than the visible light we have to deal with on the surface. (The energy of an ejected electron is soley depended on the energy of the photon that knocked it loose, which is soley depended on the wavelength of the photon).
At least in the last 50 years or so, they have been. I'm not saying members of the KKK aren't violent, but the organization as a whole doesn't go on midnight lynching rides anymore. Sure, they constantly spew a rhetoric of hatred and intolerance, but hey, if you think that kind of speech should be restriced, you're free to move to Europe.
I personally think that hate speech, the most distasteful and disturbing, should also be the most protected, precisely because it's unpopular..."It is a besetting vice of democracies to substitute public opinion for law. This is the usual form in which masses of men exhibit their tyranny." - James Fenimore Cooper.
Yeah, really a kid's game. I know the primary market is still fuzzy friendly games, but there *is* a decent selection of 'adult' games on the GC (and it looks hella better than PS2 or Xbox). Is Rockstar releasing the next GTA for all 3 consoles?
I had 5 Irish guys rooming with me for the summer, so I'm pretty clear on this. The IRA in the past has engaged in terrorist activities, true, but as part of the latest round of negs, they agreed to back down in exchange for being taken off the list. Apparently, there's been some very real reforms in the IRA, and they've pretty much backed down from being so...terrorist. The Real IRA, OTOH, is an ultranationalist, ultraviolent splinter group of the IRA that is a serious, hardcore terrorist group; they've pledged they won't stop the killing until Northern Ireland is "unoccupied" by the Brits and "cleansed" of Prottys. Good old-fashioned religious terror.
An orbiting array of solar cells with intense microwave power transmission downlinks to mid-ocean electrolysis plants. Not feasible now, but in the next 10, 20 years it could happen.
Your entire last paragraph is wrong. Fuel cells are not batteries; they do work on the same very basic electrochemical rules, but a fuel cell doesn't have a self-contained store of reactants; also, fuel cells use the much more energetic 2 H2 + 02 -> 2 H2O reaction, instead of a lower-energy ionic redox reaction like batteries (If I'm speaking Greek, get an intro chem text and read up on electrochemistry, then look at the potentials for various half-reactions). AFAIK, it's also impossible to build a "rechargable" cell that will take H2O and electricity and spit out H2 and O2; it is possible to build a rechargable battery. Fuel cells are actually a hell of a lot (potentially an order of magnitude) more efficient than internal-combustion engines; fuel cells go directly from chemical energy -> electrical energy, while an ICE has to go chemicals -> thermal -> mechanical -> electrical energy. Now for the numbers *hunts down PChem text (PW Atkins, Physical Chemistry, 7th ed.)* OK, the maximum theoretcal efficiency for a Carnot cycle engine is around 80%, depending on the delta-T between the engine and the environment; 80% is reached at around 900-1100C, at less than 100C it's limited to around 20%. Fuel cells are more efficeint at lower T, theoretically greater than 90 percent at less than 100C. Here's a pretty good summary page; the bottom graph is really good. Brush up on your thermodynamics, you're a clearcut case of a little knowledge being a dangerous thing:P
Sure, the card wasn't sent to you at your request, but the first time you signed off on a reciept, you legally bound yourself to pay it off. IANAL, but I will point out that every CC slip you sign is a mini-contract to pay off the amount "According to the terms of the card issuer" - look at your signed reciept, it will have a little 1-sentence contract on it. Of course, if you were smart and only used it at no-sign places like gas pumps and McD's, then you might have a case; but if the CC company can pull up reciepts signed by you for all your purchases, you're screwed. I hope you bought your house and cars already, outstanding unpaid debt is MURDER on your credit (trust me..)
I was in Geneva in May, it was ~1.30USD. Give it some time; at the end of the day the USD is still the de facto standard (OPEC isn't going to be switching to the Euro, that's one of the tinfoil reasons for the Iraq war - put the fear of god into OPEC). Although CHFs are starting to look nice, very very solid...
I have Season One on DVD-R, burned from mpegs from Usenet (oh god what a pain, is there any simple way w/OS X to demux an mpeg and then resync the audio WITHOUT doing it by hand in iMovie? YES i do have legal mpgs that need to be put on DVD), and it most certainly looks immeasurably shittier than the real DVD, which I'm caving on and buying tonight.
i have a mont blanc meisterstuck fountain pen - it magically arrived on my doorstep one day, from an unknown sender. best writing instrument ever, with the right paper at least; the ink turns cheap paper to pulp and clogs up the nib.
process 1 on my OS X box is init, same with the IRIX server i'm logged onto, and I'd imagine Solaris, AIX, HP-UX, *BSD, yadda yadda all use init. So, when do I get to use this on my Mac or Origin? (Just kidding...you can have my init when you pry it from my cold, dead fingers:D)
They've got the cash lying around, and SGI and Apple have much the same "image" (sexy hardware, the artsy-fartsy niche markets, small yet zealous following); it would be a great marriage - SGI's uber-badass kit (admit it, you lust after it) with Apple's killer desktop-Unix OS makes for a company that could seriously market to just about every niche in the computer industry.
Apple could replace the MIPS with Power/PPC chips, roll some cool IRIX tech and hardware support into OS X, maybe even binary compatibility (good luck, I know) and BAM - 1,024 2GHz PPC970s (or POWER4s if you wanna get serious) in a single-image NUMA Octane 3000 running Panther. Throw the xlc compiler on there and that's some good G5 lovin'!
