- It appears that "solid state harddrives" are now reaching useful sizes 
and sane pricing levels. (E.g., when I first looked at this it was 
something like £1,000 for 10 GB, which is obviously absurd. Now it's 
something like £2/GB with sizes up to 250GB.)

- nVidia's latest and greatest is the GeForce 200 series. The 260 is 
expensive, but not extortionate. The 280 is several times the price. 
However, every benchmark I've seen shows the 280 as about 20% at best. 
Given that it's far more than 20% more expensive, that doesn't seem like 
great value for money. I'm considering buying a 260. (My GeForce 7900GT 
is slowly dying...)

- It seems that AMD's CPU designs still trail Intel by a wide margin in 
terms of performance. I think AMD might give you more performance for 
your money, but if you want the fastest CPU it's not going to be an AMD 
product. And Intel's offerings mostly seem to be a reasonable price. 
(Obviously anything that says "Extreme" on it is 400% more expensive but 
only about 6% faster.)

- For ages every Intel CPU going has used the same socket. It seems 
there's a new one just come out, and currently motherboards for it are 
absurdly expensive. (Like, the motherboard costs more than the CPU!) I 
think I might wait for the prices to return to sanity - as inevitably 
they will - and then make a purchase. (Curiosly, the CPUs themselves 
aren't *that* expensive, considering they're brand new.)

- I've been looking at watercooling. Just to find out how expensive it 
is. It seems there are kits selling for about £50, but if you buy all 
the components individually it could easily cost £100 or more. (The 
waterblocks seem to be the expensive part - especially for GPUs.)

- On a similar theme... Most people spend about £6 on a PSU. It's 
amazing what you get if you spend a tiny bit more (e.g., £20). What's 
even more amazing is that you can spend *hundreds* of pounds on 
31337-gamer PSUs if you wish.

- Likewise, cases start at £10 or even less, and go up to several 
hundred pounds if you want something ridiculously over-styled. Of 
course, all the expensive cases are aluminium rather than steel. (I was 
recently very surprised to learn that hyper-expensive aluminium is 
actually *less* thermally conductive than plain ordinary copper. So... 
why don't they just make cases out of copper??)

Every time I turn out to a clan meeting, everybody brings along their 
uber-gaming rig. You know the kind of thing - insanely over-styled 
casing with big transparent windows, fans that light up, internal case 
lighting, elaborate watercooling systems with polished chrome fans, 
multiple graphics cards the size of a car, high-capacity HDs in 
front-loading hot-swap drive bays, etc etc. And then there's my PC... 
which is just a PC.

I could almost go for the insane look... :-P

Paint it black and put yellow racing stripes on it. Black paint is 10% 
faster, and yellow racing stripes give it a 50% speed boost. You could 
get another 20% buy cramming the case full of high-intensity blue LEDs.

Hey, do you remember the old PCs that used to have a "turbo button" on 
the front? Why the **** would you ever turn that off?! o_O

No need; the case fans already have two blue LEDs that light up the room 
sufficiently for photopic vision. :-P

Old Games. Programmers used to rely on the fact that the processor ran 
at a brisk 4mhz, 12+mhz caused the game to run too fast to be playable.

No, you must cram it full of LEDs! Not only does it need to be bright to 
get the speed gain, but it has to be blindingly bright. Because 
Blindingly bright = Blindingly fast, you see.

for an extra  15%  add a few fans with a flashing multi-color light 
show. You know the kind ...

WTF? Why would they - oh, wait... CSS malfunctions if you play it on a 
dual-core CPU. (Something to do with directly accessing the CPU's 
realtime timer - which, obviously, is different on each core!)

But of course, for Ultimate Speed you must use ultraviolet, together 
with components containing inks that will respond to it...

(Seriously, you can buy cooling fluid that costs extra because it 
floureses under UV. WTF?)

Well, way back in the dark ages, they didn't really expect the CPU clock 
speed to change, so their timings were based on how fast the processor 
executes instructions. Of course, when faster systems started coming 
out, they had to change their timing strategy.

CSS failing on a dual-core is probably due more to race conditions, or 
other synchronization issues.

Heh. Delay loops FTW! :-/

Well, it doesn't actually "fail", it just runs irregularly. As in, you 
get an even higher framerate than normal, but it looks visually jerky. 
(Or it did. They've fixed it now.) You used to have to manually set the 
processor affinity to fix it.

Woo! I just found a Sun server that costs more than my house! :-D

(OTOH, it *does* have 64 quad-core SPARC-64 VII processors in it...)

Looks like it's bigger than my entire server rack too. Cute.



At the other end of the scale, it appears that Sun now sell ordinary 
desktop systems capable of running normal desktop software. They look 
pretty, and they're not *especially* expensive either. (Like, a few 
hundred pounds for an Intel Core 2 Quad system.)



Also... Somebody pointed out a website where you can select and 
configure your own PC. It's not a very *good* site (e.g., you can't see 
the prices for individual components, only the final unit, you can't 
select all that many options, many things aren't documented very much, 
etc.) But it's strangely addictive trying out various combinations of 
components.

Sometimes you just want to see how much stuff you can cram into the box 
without going over budget. And other times you just have to select the 
biggest, baddest mutha you can, just to see what the hell the price tag 
comes out at.

In summary, it appears that for about £3,000 I could have a REALLY 
FREAKING NICE PC. ;-)

I don't understand the appeal of churning out lots of money to turn a 
hammer into a kitsch object.

But then again, computer to a layman is nothing but a gateway to games, 
music and video -- with some office software used to spellcheck emails 
to justify the price as opposed to a mere games console.  Beautiful 
keyboard, mouse, monitor and casing are far more important than whatever 
is on the inside -- the computer itself...

I thought the blue leds were for cooling. ;)

Yeah, it does seem that way.

A bit like those people who buy a Vaxhaul Nova and then try to make it 
look like a Ferrari.

Well you needn't! Just work for your local council. I'm sure *they*

Yeah, something like that.  When nobody needed more than 640K, part of 
the "reason" was there was no need to write code that ran at a constant 
speed regardless of the processor speed.  Until you had "turbo" machines 
with 8-12 MHz, running a game like Pole Position at 3-4x normal speed 
made it difficult to play.

There were TSRs written for MS-DOS that did just that for machines that 
had faster processors but no turbo button. :-)

News today: an 8GB *RAM-based* solid-state drive:

Transfer rate 6GB/second, except SATA doesn't support that much! :D

The key word here is *look*.  I prefer to get a car that looks like a

that looked and went like a Ferrari, but they're quite expensive.

You forgot the exhaust system! Gotta take out the carefully designed

Yes! Because we all know, making your car sound like a 2-stroke 
motorbike gives it the power-to-weight ratio of a 2-stroke motorbike! ;-)

Heh, reminds me of one of our local shops. We went in there to buy a 
replacement battery. While they do sell those, most of their range is... 
well let me put it this way. They sell allow wheels. Bucket seats. They 
had a "rally" stereo system on display. And they also sell panels of 
LEDs that flash. (?!) They don't do anything, they just look high-tech.

That store went bankrupt a few months ago...

It's crude, but I call them "Fart pipes"

Though a decent tuned exhaust does sound nice ...

But sticking a tailpipe with the diameter of a coffee can on your car 
does nothing, but make your car sound like rolling flatulence.

And, someone once said if your car is loud, you're not getting the most 
performance.

And whatever you do, don't get me started on Harley Davidson motorcycles.

I'm still puzzled about the Race of Champions. They raced several 
designs of car which seemed to be using *external combustion* to propell 
themselves, rather than the more traditional *internal combustion*. (As 
evidenced by the huge flashes and bangs as they raced round the track.)

That's quite common on race-tuned carburetor-engined cars, under certain 
circumstances they simply pour so much fuel into the engine that some of it 
goes unburnt through the exhaust system and ignites once the exhaust 
mixtures mixes with enough oxygen in the atmosphere.

You would think, though, that if that fuel had burned inside the engine, 
it would deliver more power. And since the goal of any race-tuned engine 
is to produce maximum power......

Not sure how true that is, formula 1 cars sound painfully loud yet the 
clever bods there so far have not come up with a way to make them quieter 
and generate more power at the same time...

Also I guess the silencer in your road-car exhaust system sucks a bit of 
power (the engine has to push harder to push the exhaust gasses through it), 
removing it should make your car louder and a bit faster.

Maybe someone could find a way to convert the sound energy from an engine 
into mechanical or electrical energy...

Hehe... All the classic cars rush past sounding like a pack of angry 
bees, and then an F1 car comes out, sounding like an angry mosquito.

There's something deeply amusing about an angry but tiny animal...

I don't know about that - I tried driving my car with no silencer, and 
it was *actually impossible* to exceed about 25 MPH. The car simply 
would not accelerate, even on the flat.

(OTOH, it was a fairly old car. But normally it would happily to 90 or so.)

No, there is a limit to how much can burn inside the cylinder, it's better 
to dump in slightly above this amount rather than slightly below it.  Of 
course modern engines can control electronically the amount of fuel way more 
accurately, and especially in road cars you certainly don't want to be 
wasting fuel out the back!

Something to do with the F1 car engine rotating at 3x the speed of the 
classic cars.

OK, so maybe you need to redesign the other parts of the exhaust system that 
were designed with the silencer in mind.  But there's a reason why race cars

Yeah, probably that. ;-)

Actually, what was notable about the F1 cars wasn't so much the speed, 
but the *acceleration*. You see the cars go past on a straight, and it 
looks just like any other road full of traffic. But we sat at 
Silverstone on a corner. The cars would come up to it, go round it quite 
slowly, and then just *VANISH* off into the distance like they wer toy 
cars made of paper... it was pretty insane.

Also, watching an F1 car going round the tiny, twisty indoor circuit at 
the RoC, I noticed that it sounded like the engine was on a limiter the 
whole time. It produced a constant note like a tuning fork. Then the 
driver did a few dounuts, and it's amazing how quickly the engine revs 
up and down. Like it just has no flywheel at all! Heh.

   Agreed. There was motorbike back in the late 70's, early 80's called the 
Honda 400/4. I think it was the first to use a 4 into 1 exhaust sytem at 
that engine capacity. Hugely popular simply because it sounded fantastic. 
(It moved a bit too!) :)

Acceleration is determined by the power to weight ratio.  A "normal" family 
road car has perhaps 70-90 HP per ton, a fast sporty road car perhaps 
130-150.  A formula 1 car has about 1300 HP per ton.

Probably, without an electronic limiter the engine would likely self 
destruct quite quickly.  And for demo purposes I guess they turn down the 
limiter to quite a low RPM to avoid needlessly damaging an engine.  And the 
driver probably just had his foot to the floor bouncing off the limiter the 
whole time.

Pretty much no flywheel, no, that's why whenever some non-F1-driver tries to 
drive one they usually stall it immediately.  Once the car is moving of 
course there is not really any need for a flywheel.

Hmm. Good point, though. Just about any racing engine is painfully loud.

And that logic may only apply to certain kinds of noise, and maybe only 
to street vehicles. Something about how the resonator in the exhaust 
pulls more of the exhaust out of the cylinders, allowing for a better 
mix of fresh fuel and air.

Of course, it could all be made up by some anit-noise group...

Just don't put a straight pipe on it and drive around neighborhoods at

And try not to set off too many alarms on parked cars!

 LOL, I totally agree. My mates have Harley's and I've often wondered what 
locals think about the noise.

I had a friend who did rally racing. He had a car that looked like a VW 
beetle that had been rolled down a hill. (It was.) It had a V8 in it, with 
racing tires, two sets of brakes, all that. Was fun to blow away the camaros.

Only problems are: a) slow (faster isn't much faster, and costs double), 
and b) limited number of "write cycles". And, no, the 250GB one is not 
$2/GB. lol

I didn't say $2/GB, I said £2/GB. Different currency. :-P

http://www.ebuyer.com/product/152605

250GB solid-state drive, £529.89. That's almost exactly £2/GB.

As for "slow"... presumably the win is the massive decrease in seek 
time, rather than sequential transfer speed. (I think I saw a benchmark 
somewhere... but I bet I can't find it now.)

.... and maybe also more expensive? I mean, people actually begin to steal cables
from construction sites... and not by the spool, but by the yard...

And then I guess it's also heavier than Aluminum, which I'd suspect to be the
main reason for gamers to get an Alu casing: Carrying it to the LAN party.

Yeah, but they used up precious memory, which the Turbo didn't ;)

In addition, the TSRs would make the system run a bit less smoothly.

Magnesium. The ultimate in portability. My camera still blows me away, 
the chassis is a Mg alloy and feels like plastic.

Of course, I don't know how well Mg deals with heat.

Absolutely.  Managing TSRs was always a lot of fun. (OK, maybe not).

They could, but my experience was generally good.  Unless the TSR was 
poorly written, in which case it got used only once. :-)

I just had a picture flash through my mind (if you'll pardon the pun) of 
a case made out of pure Magnesium.  In my mind's eye, it didn't last very 
long, but it was spectacular. :-)

But very popular. Indeed, Sidekick was why people invented the SysRq key.
