Low power WON'T bag ARM the server crown. So here's how to upset Intel

Nigel 11
Silver badge

Re: Nothing new here

What is it that you need in the server farm, that you can do with hardware integrated on the same slice if Silicon as the CPU, that you can't do with a separate piece of silicon attached to an Intel CPU's external bus?

I appreciate that at the consumer device end, there are serious economies to be reaped by integration of a system on one chip. (Serious economies means maybe a few tens of dollars per system). In the server room, I don't think a $50 cost advantage will win any arguments. It needs to be a technological advantage, or a price advantage at least one order greater.

Ultimately, I do expect Intel will be fabbing the world's ARM CPUs with their world-leading process technology, but in the first instance for mobiles, not for servers. ARM will conquer the server room last, if ever.

Scientists discover supervolcano trigger that could herald humanity's doom

Re: Hold This (while I press the big red button)

Actually it's conceptually easy to trigger a supervolcano erruption. Drill down as far as you can, maybe 500m above the magma, then put a "Tsar Bomba" hundred-megatonne nuke at the bottom and similar nukes every 500m or so all the way to the top, and blow them all at once. Fortunately, I don't think even the leadership of North Korea is quite that crazy. (Scarily, ISTR that there is a supervolcano reservoir inside North Korea's borders).

Re: and I live on top of one of those 20

Definitely no joke. I'd be planning to relocate as soon as reasonably possible. Vesuvius errupts far more often than supervolcanoes. If you leave relocation until there's smoke coming out of the volcano, it may be too late to get yourself (and the entire population of Naples) safely out of town.

Statistics

No consistency problems. Erruptions of different supervolcanoes are not correlated. Erruption times of a single supervolcano are vaguely cyclical, but not anything like clockwork. So the earth has had two go pop in the last 100K years, and may have none go pop in the next 100K years, averaging out as one every 100K years.

In reality (a) you'd have to average over a few Myears to get meaningful statistics, and (b) the Yellowstone supervolcano is likely to go pop in the geological near future. (Say in the next 100k years with probability 0.7 or higher).

Red Hat teams up with community-based RHEL lookalike CentOS

Nigel 11
Silver badge

Historical background

The previous history is relevant.

With RHEL5, it was easy for Centos or anyone else to strip out the Red Hat copyrighted images and repeat Red Hat's build process using the open sources which Red Hat are obliged to distribute. They didn't care that Centos (and CERN - Scientific Linux) did this. They did care when Oracle did the same.

So with RHEL6 they made the build tools less open and more obfuscated, and that's why Centos 6 arrived a rather long time after RHEL6 (they had rather a lot of reverse-engineering to do). Centos was "collateral damage". Oracle was the target ( it was basically taking Red Hat's software, relabelling it, and reselling it in competition).

I'd feared that they would complete the process with RHEL7 and make RHEL 7 close to uncloneable despite the open-ness of the source. Does anyone know if they are freely licensing proprietary build tools to Centos and other free-beer distributions, while leaving Oracle to stew? If they are, it seems like the best possible solution.

Re: Harvesting spare static electricity

I'd have thought a better solution would be those power cells that metabolise glucose.

Good idea for implants in blood-perfused tissue, but the surface of an eye is not well-supplied with blood or glucose.

The best way for an eyeball implant would probably be photovoltaic ("solar power"). Eyeballs are well supplied with light, at least while you are awake. Transparent solar cells can be made (indeed, large ones are being installed as windows on "green" skyscrapers).

Another way would be wireless power (I'm assuming only microwatts are needed). You'd need to wear a power transmitter elsewhere on your person if continuous power was needed. You might be able to scavenge power from a 21st century environment if continuous power was not vital. (ie, parasitise off WLANs and mobile phones).

Yet another way would be piezo-kinetic power scavenging (as in the Seiko Kinetic watches). Again I can see that working much better for implants in other parts of the body.

Re: Excellent

We don't want them being used as fetish objects or clubs by the cave-dwelling man apes that will wander the post-apocalyptic wastelands.

Or maybe we do, provided they're suitably resilient. Something that's periodically rediscovered and regarded as treasure from the great ones of yesteryear may stand a better chance of finally being decoded, than something lost in a hole in the ground getting buried deeper and deeper with every passing milennium. Tableware made of a high-tech ceramic much tougher than mere porcelain might be a good choice. If some barbarian manages to smash it and dumps it in a midden, the information loss probably isn't very great.

Anyway you'd run both strategies in parallel, with very many identical plates for redundancy.

Try pottery?

Perhaps this method is right, for billion-year timescales.

If we're aiming only at the next civilisation after this one fails, or perhaps the next intelligent species after this one goes extinct, then a Babylonian solution beckons. Fired clay tablets (with a modern twist). Perhaps a somewhat more advanced ceramic, such as the all but indestructible "Corelle" that Dow Corning once made plates from. (Same problem as un-ladderable stockings. The plates last forever. No repeat sales. No profits. Discontinued. Sigh. )

You could put some low-tech diagrammatic writing on the plates, in an attempt to draw attention to the high-definition data embossed in the ceramic, or ink-jet printed at ~100dpi. Make them both beautiful and startingly hard to break, and stone-age or barbarian peoples might preserve them rather than destroy them. Anyway, it's really hard work to destroy the information on a ceramic surface and a subsequent civilisation will reassemble the fragments from your rubbish tip. Make lots and lots of them, distribute them as superior mass-market tableware, and survival of some of them is virtually guaranteed. All we need is a billionaire with a long-term view of things to underwrite the project. (Thinks ... an Indian one ... must be good for a lot of positive Karma. The largest Hindu unit of time is a large multiple of My, and they believe in re-incarnation and in cycles of creation and destruction. It all fits. )

(Apparently we know more about the everyday minutae of Babylonian life, than about any civilisation since! )

Re: I think that ...

The Earth will become uninhabitable a lot sooner than 5 Gigayears hence. We're actually rather close to the inwards edge of the habitable zone around the Sun, and the Sun is getting hotter as it ages. Unless "we" initiate major planetary protection operations within the next Gigayear (orbital sunshades, or orbit expansion), life will be over by then. Some estimate as soon as 300My, before Earth suffers thermal runaway the same as Venus. (OMG multicellular life is having its midlife crisis! )

If we want to leave a *really* long-term record, Earth isn't really the right place. Too much corrosive oxygen and water and those awkward plate tectonics, and a boiling sulphuric acid nightmare after the end of life on Earth.The Moon is better (dig in deep to protect against all but huge meteor strikes, and position-mark with long-life radioactives near the surface). An outer moon of Saturn would be better still, might even survive Sol going red giant and nova. (Ring any bells? ....)

Re: Galileo

I'd be most surprised if he didn't start by dropping weights. It's not hard to distinguish clunk! from clunk-clunk!, where the impacts are separated by as little as 50ms (maybe less). Then he thought "that's interesting". Then he'd have looked for a way to make the experiment more accurate, and got lucky by using solid rather than hollow spheres on an inclined plane. Right result, but missing a large chunk of reasoning about then-unknown rotational kinetic energy and the importance of the spheres being homogeneous.

Re: Equivalence Principle

Good question.

The gravitational interaction of two human-sized objects has been observed, and Newton's law of gravitation (inverse-squares) confirmed for masses of the order of kilogrammes at distances of the order of a meter. The experiments are very hard, and the accuracy isn't great. Some alternative theories have proposed that gravitation breaks down on milli- or micro-meter scales, and of course at much smaller scales still we get into quantum effects. These aren't yet testable.

Other theories posit that inverse-squares gravitation breaks down on the scale of a galaxy and above, and attempt to explain away dark matter and dark energy in terms of a different law of gravitation on very large scales. So far, such attempts have not been very successful in doing away with the need for dark matter and energy to explain the observations.

The equivalence principle is much better-tested for terrestrial masses, than Newton's law itself. But all the masses tested were made of conventional atoms. Perhaps fortunately, we don't have neutronium or large masses of antimatter to play with.

AFAIK the orbits of the Voyager spacecraft are still observed to be not quite as expected. Tantalizing, but they weren't ever designed as gravity probes, and their deviation from predicted orbit is just within the likely errors of observations.

Re: how?

I haven't worked out the details (which will be very complex, probably involving serious supercomputer resources to model) but there will be gravitational perturbations of each orbit by the other bodies. Here in the solar system, the existence and position of Pluto was deduced and calculated by very careful observation of the orbits of Uranus and Neptune. Once they knew where to look, they pointed a powerful telescope at that patch of sky, and there was Pluto.

For this system we can test GR rather than simple Newtonian gravity, because the bodies are very dense and close. It tests the equivalence princible, because a Neutron star is made of Neutrons and a White Dwarf is made of ordinary atomic nuclei (ie with protons, and electrons between the nuclei). Short of a black hole, that's about as much different as two astronomical masses can be. (*)

I'll have to file this system along with Zircons dating of the age of the Earth. $DEITY is being extremely kind to us, providing us with the means to scientifically investigate questions we might have thought were forever beyond our grasp.

(*) I've always wondered whether bosons (commonly neutrons and protons) and fermions (commonly electrons) are gravitationally equivalent. Is there any way to probe this, even conceptually, given that the electromagnetic interactions of electrical charges are about 10^40 times greater than any gravitational effects?

Here on Earth, if you put the feather on top of the hammer and drop in still air, the feather will fall with the hammer. The hammer pushes the air out of the way, and gravity does the rest.

I'd be very surprised if Galileo hadn't tried this, thought he was probably smart enough to realise that the limitations of this particular experiment would be siezed upon by his enemies.

Re: My advice to Mozilla

Mozilla doesn't have to hope anything. Firefox works just fine on Linux and anything else that might replace XP and Windows 7 on business desktops (including the Windows 8 desktop).

The day Microsoft announces EOL for Windows 7 without having an upgrade path that doesn't involve massive costs (including retraining all a business's low-skill keyboard-pokers), is the day Microsoft will have signed its own death warrant.

If I hadn't been around while Digital self-destructed, I'd think it couldn't happen.

There's actually a decent successor to Windows 7 in Windows 8, if only it could be made to boot to desktop with a 7-compatible login /switch user screen and start menu, and TIKFAM made so it can be defaulted hidden and configured completely unavailable using AD policies. Doesn't actually look too hard, if Microsoft would only stop pushing TIKFAM at business users who know they absolutely don't want it in any shape or form.

Personally I wish they'd decide that there never will be an official version of Firefox that works anywhere on Windows 8 except for the Windows 7-compatible desktop, until someone stumps up the entire cost of porting it.

If Microsoft think the non-availability hurts their chances of persuading people that TIKFAM is any more seaworthy than the post-iceberg Titanic, let them pay the Mozilla foundation to do the port. If Microsoft doesn't care to do that, tell the world that's why there's no TIKFAM-Firefox.

Haswell micro: Intel’s Next Unit of Computing desktop PC

Re: No passive cooling!

A thought on the NUC form-factor.

Intel needs to put more SATA connectors on it, not just one, so that it can be used as the basis of systems that need >1 hard disk. (IMO every system with locally-stored data needs >1 hard disk, for mirroring - at £40 for a HD can you afford not to? ) How much do four SATA connectors cost? Surely on-chip SATA interfaces are (or can be) designed to idle at microwatts if there is no hardware connected to them? There's clearly no great cost to putting six SATA on desktop boards that rarely have more than three of them connected. If there were, they'd leave them out and the minority would buy PCI-X SATA controllers.

You could connect extra disks by extending the NUC upwards with a section that bolts on top of the NUC box and holds the disks. Keeping the original lid and bolting that on top of the extended NUC would be a nice touch.

If the form-factor catches on the price ought to drop as NUC-format boards start being made by ASUS, Gigabyte etc., along with cases for passive cooling, multiple disks, etc. in various different shapes.

Intel set the ATX PSU format and the common desktop motherboard formats ATX, mATX, ITX. OTOH they failed to persuade anyone that BTX PSUs were a good idea. Standard form-factors are a good idea in principle.

Re: Passive cooling - FOUND!

For the record, if anyone finds this post with Google, I have at last found my passively cooled ITX board with a faster CPU than an Atom. It's a Gigabyte GA-C1037UN-EU. The -EU is important because there is another variant with a fan and (I presume) a wimpier heatsink and/or a different BIOS that will moan if the fan isn't present.

The CPU is a Celeron 1037U, 17W TDP, which CPU benchmarks about 2.5x my Atom. It also takes up to 16Gb of DDR3 which should save on disk IO. The board (incl CPU) is inexpensive (£72 incl VAT and shipping) and even boasts 3 x SATA (one of which SATA-3, great for an SSD), USB3, and one E-SATA.

Fingers crossed. Intel shouldn't be marketing these chips as Celerons. They should market them as low-wattage low-end Ivy Bridge i3 (which they are), or even as faster Atoms. There's a Haswell version coming "soon", but I decided not to wait for it.

Passive cooling?

I presume it still has an annoying fan in there somewhere, which is why IMHO it doesn't warrant a premium price. (If I''m wrong and the whole case is metal acting as a passive heatsink, please correct me and I'll reconsider).

What I want is a passively cooled board that will fit in an ITX case, to replace the Atom D520 I have at present. Having gotten used to silence, I don't want even a whisper of fan noise. Nobody seems to make such a board, though there's an i3 laptop CPU that's loads faster than the Atom and which has much the same TDP.

Failing which I'll be returning to a mini-tower case with a fan-less PSU and a NoFan heatsink on an ordinary Intel desktop CPU. Small size isn't a killer feature. Silence is.

A long time in the planning?

It was quite a few years ago that IBM sold its hard disk business. At the time there was speculation as to motive. Was it simply because IBM saw it was labouring under a disadvantage, trying to sell its hard drives to competitors in the server space such as HP and Compaq? Or was it because IBM believed this was a business with a declining long-term future, and sold out before that view became widely held?

I suspect the latter. They compare IBM to a elephant. It can't gallop, but it can move surprisingly fast and knows better than most large companies where it is and where it wants to get to.

Re: So now all we need..

At the small end you could try a Cubieboard, with 1 x SATA on board. BTW Linux supports SATA port multipliers (forget the exact right term - but like SCSI LUNs on SATA, can attach four or more drives to one SATA port). Might be a fun project.

At the bigger end you could stick with Intel and get an Avoton server with 12 SATA ports. http://techreport.com/news/25703/asrock-combines-avoton-soc-12-sata-ports-on-mini-itx-mobo

There are plenty of whisper-quiet Intel solutions. Start with a low-wattage CPU (think 35W TDP is the lowest). Then research all components with fans. Typically you use a large case with a 12cm fan running at minimum speed and a large-fan CPU heatsink which again will result in the fan running at minimum speed (or off most of the time, if the motherboard is chosen to be capable of running the fan at zero rpm when the CPU isn't in need of any cooling). You can get completely fan-less PSUs. You'll also want to choose hard disk drives with care lest they be the noisiest part of your system. WD "Red" aren't the fastest, but they may be the quietest. I can't hear them seeking at all!

I've been trying to find a mini-ITX board with an Intel i3-4210U soldered onto it and passively cooled (15W TDP) but nobody seems to make that. Annoying. (I have an Atom-based home server which I'd like to speed up, but not at the expense of starting again with an Intel NUC and a 3rd-party passive-cooling case and not at the noise cost of even whispering fans).

Would destroy anything based on high-speed decision-taking and ultra-high leverage. The first, because a human can't input a trade in less than a few seconds. The latter, because the risk from fat-fingering it would be too great.

Just because something can be done does not mean that it should be done. Trading faster than a human being possibly could is one of those things. Doing so with ultra-high leverage puts the stability of our entire financial system at risk.

Re: solar power will be the limiting factor on what humans can do in the long run

Todays nuclear reactors have outputs that reach the MW range on a surface that would take a solar farm half a continent to replicate.

Bollocks! A small fraction of the Sahara desert alone could generate more electricity than the human race currently uses.

The Solar radiation flux onto Earth's surface is about a kilowatt per square meter. Allowing 10% for harvesting efficiency and a factor of two for dark night-times. you need 20 m^2 per kW power-station output. A large power station is a Gigawatt: a million kilowatts, or 20 square kilometers of desert covered in solar panels.

Controlled nuclear fusion would be great if we could get it working (economically). So far, we can't (at all). Certainly worth continuing to try, but ... in the meantime, solar panels really do work, and offer an alternative should fossil fuels become uneconomic or accepted as too damaging to use. Solar panels are already cost-competitive with fossil fuels where there are deserts in close proximity to cities (for example, in Arizona).

Re: I don't understand

Maybe something to do with the fucking great piece of lead that it's stored in.

And probably even then, the driver wants a good bit of inverse-squares law on his side. Like most of a truck's length?

Now you know another reason why slip-streaming or staying in a truck-driver's blind spot for a long time might be bad for you!

Re: I never saw the point of this concept.

Meaningless strings of words, I agree. But can't you see that the "Pheasant plucker" is a minor masterpeice of something like wit? The moment you notice where you might go wrong, some perverse subsystem in your brain wants to go wrong. And there are so many ways to choose from!
