I'm not familiar with functional programming being used to create CPU RTL simulators, or do hardware synthesis. Are there any academic or industry papers on this you could point me to? I have heard very little of practical uses of functional languages outside of schools, but I'd like to be educated.
So can we fabricate things out of these tube structures, like that modeling I mentioned in the original post? Or are these more like tubes that carry liquids or individual atoms?
Any word on what they are good for, or is it just a milestone in nanotech???
Functional language programming is still very application specific. We are talking about general purpose processors.
From my perspective, there is no plateau in sight. Intel is shoving more cores on die for less power than p4. That's a huge improvement. I wouldn't be surprised if they do what they always have done and push a single technology to its limtis in a very short time.
In terms of using that horsepower, bring it on. When I can spawn a dozen GCC commands and compile very large projects locally without needed distributed computing (ie, cpu core simulators, c compilers, hardware synthesis), I will be a happy programmer.
In my line of work, CPU throughput is _always_ the bottleneck.
You should take a look at some multithreaded code sometime. It is rare that the application designates the processor affinity. Generally the programmer starts a new thread and lets the O/S schedule it, as it and the HAL are more aware of any assymmetries in the underlying logical CPU structure.
It will have an advantage right out of the box: windows already schedules hundreds of threads and processes, it will automagically take advantage of the extra resources. Same goes for SMP linux cores.
This wasn't the case 10 years ago, but due to dedicated individuals and market forces, modern OSes are multi-core ready.
That was an interesting link. I stopped reading freerepublic years ago to lower my blood pressure. I forgot they don't take kindly to certain kinds of intrusions. Personally, any law that stands between me and sufficient choice of pr0n is headed down the wrong path.
preface: my nanotech is limited to semiconductor process only.
looking at the image, the towers appear to be 20um cubes, and the tubes look incredibly uniform. That is some impressive feat to build such a tall structure!
this makes me think of 3D model creation tools that use a laser and a tank of epoxy-like goop to 'draw' a 3D prototype of a design.
can this accomplishment be extended to this technique to "render" nanodevices (er, microdevice machines), out of tubes?
good point: why is censoring clan made propaganda (blue state censorship) different than censoring janet's boobie or evolution (red state censorship)?
while I agree with you, just for future reference: political incorrectness is just as much a rally point for conservatives as it is for liberals.
ever watch a conservative bristle as being labelled a "religious zealot", and then demand that they are not all like that?
that's political correctness.
or, using another generalization that since the majority of clan members are conservative, then conservatives support clan members?
that kind of illogical statement is also politically incorrect, but goppers don't like to say the letters PC. it makes them queasy to acknowledge Political Correctness is an apolitical designation.
No offense dude, but America is an incredibly religious country that lives in fear of angering the almighty. I think a small % of the country would agree with you, mostly blue states.
Maybe becuase they think this is a moral issue that is directly contributing to the downfall of God, America, and Apple Pie? The religious right has a collective hard-on to make everyone into the image of what they think good christians should be. So why not stamp out this source of evil that is polluting the minds of our children?
As for locale-based governing: I was watching the PBS special on Koinonia Farm, an integrated town in the South in the 50's that was the target of insane amounts of racist violence.
Where to draw the line of Federalism? I wish I knew.
common misconception about more == better: an open air platform has worse thermal characteristics than a properly designed chassis with the fewer # of fans. In other words, just because your chassis has big vents in it doesn't mean it will cool well. You need a well designed chassis that channels the fan's efforts to move air over the parts. UNfortunately, custom OEM chassis will always outperform generic chassis b/c they can taylor the internal plastic fittings to most efficiently move air with fewer fans.
Case and point: (no pun intended): I have a Dell inspiron from a year or two ago that has one fan and a molded plastic insert. It is essentially silent at 2.6GHz when playing WarCraft. Just before buying the dell I spent a fortune on a silent supply, funky fans, zallman heatsink and an aluminim chasssis, and with the exact same component configuration as the dell, it is easily 5x louder (subjectively) playing the same game.
based on this, and experience in a chipset validation lab, i think it is smarter to buy an intelligently designed OEM system if you truly want a quiet PC.
but i'm 35 and have been a fan since i first saw the series on PBS in the 80's, and I can't WAIT to see this. it looks great, and i'm excited to see a new interpretation. if you've got a problem with it, you need to either (a) grow up, or (b) take a frikken antidepressent or something.
I agree with your "fear of anything nuclear" sentiment: I'd rather have rods of waste to bury than breathing clouds of acid gas from coal plants.
You're also dead on about the third rail thing: there's too much money in energy.
I do think there are natural limits: even a type II civilization still runs out of planetary resources. This told, excessive consumption of energy is usually a symptom of other run amok things: overpopulaton, pollution, and other dirty "liberal" things.
I'd like to see neighborhood pebble bed reactors PLUS a strong sense of keeing the community clean. WHen people have to piss where they drink, you can damn well believe they'll take great care to recycle it. As it is now, the excessive consumption of energy translates into shitting on everyone else in the world.
Safe nuclear power will help change many things for the positive (I bet Chinese cyclists will be happy to not have to wear face masks anymore), but it isn't the holy grail of healthy living.
Firefox already claims to block popups, but I still get them when I go to Drudgereport. Sure I could install Adblocker, but it is a bitch to keep configured and to always turn on and off when using my local intranet.
So you're point is mainly utopian: Firefox has already failed to handle popups in a satisfactory manner, and you think they will be able to handle legions of advertising hackers?
I'm hoping you're right, but the realist in me says, "Not bloody likely."
yeah, but i can't find any headphones big enough to find around my gigantic nerd head, and my hair is so greasy they just slide off and land in my trough of cheetos...
My PS2 is already unnacceptibly noisy. When playing dramatic games like Silent Hill, the sublte nuances are drowned out by the WHIRRRRR of the PS2 box. I guess I should lock it up in a cabinet or something.
I can't imagine something this big and fast being quieter.
Actually, you DO get automagical compiler speedup. In some cases it can identify vector-izable (is that word?) loops and promote them to SIMD operations.
But yes, otherwise, you need to re-code if the compiler doesn't take the hint, especially in structures/classes. The only objection I have to the Intel intrinsics is they don't look pretty!;-)
I haven't used VTune since circa 1998, and it had this awesome feature that would point out boneheaded things in your code. One interesting suggestion it made: it noticed I wasn't using return values despite returning them, when I removed them, I got a 25% performance boost in some critical code. Made me feel like an eeeeediot.
Seriously, that was crap. He bitched about how idiotic passwords are for 95% of the article without ever explaining why. He mentioned keyboard attacks and lazy administrators, and hinted at ATM security, but it was essentially and angry man venting at a hypothetical IT department.
How about some facts or something we can do to improve the issue, or some background, rather than crying for two screens worth of html.

Dual CPUS on the _same die_. Intel and AMD have had point-to-point DP architectures since the mid 90s, long before Apple.

Sorry kids, this is essentially an Embedded CPU.
Intel has had their XScale running at >1GHz and under 1W for over FOUR YEARS.
AMD is finally playing catchup, but at 400 MHz, good luck.
but i'm 35 and have been a fan since i first saw the series on PBS in the 80's, and I can't WAIT to see this. it looks great, and i'm excited to see a new interpretation. if you've got a problem with it, you need to either (a) grow up, or (b) take a frikken antidepressent or something.

really?? by "about" box says 1.0
the popups i always get are from Tickle (the IQ test) and the University of Phoenix.
my CPU is making noise right now, it's saying, "anonymous coward loser alert!"
Um, what?
