Habitable HEAVY GRAVITY WORLD found just 42 light-years away

Re: Wrong end

We need to suss out what makes us what we are, and implant that in a body that has fewer stringent requirements for survival and doesn't age, something that can use anything as fuel, has a long sleep/hibernation mode.

Silicon chips optimised for energy efficiency, clocked very slowly during the long boring bit in interstellar space? Can't beat the speed of light, but can crank up subjective speed by any desired factor just as long as the hardware in the real world lasts the voyage.

Uploading a human being into a virtual reality is the hard part of the problem we haven't addressed yet. Indeed, we don't yet know for sure whether consciousness is a wholly classical phenomenon. If it's quantum in nature, a personality (soul?) is not uploadable to any conventional computer, and is not uploadable at all without destruction of its original. This is where physics meets theology via IT.

Re: EE 'Doc' Smith? Larry Niven?

An elephant is about the largest land animal (mammoths and dinosaurs were somewhat bigger). But that's on Earth, at 1G.

Consider stumbling and falling. Impact kinetic energy after a fall of any stated distance at 2G is the same as that for a fall of twice the distance at 1G. For a human, a pratfall at 2G would be like falling over the edge of a drop of his own height at 1G. A twelve-foot fall won't always kill you, but it will sooner or later. Big terrestrial animals (horses or larger) often die if they fall while running, but 4-leg stability means such falls are rare enough for the species to survive. Surviving a broken leg is also difficult to impossible for a large animal, and at 2G the load on the legs is doubled for any particular body weight.

Now consider 5G rather than 2G. 5G means the impact from falling over is the same as falling five times your own height on Earth. And consider that with a multiplied G force, you'd have to react many times faster to correct a postural instability before it becomes uncorrectable and results in a fall.

The elephant in the room on a 2G planet will be at most the size of a small pony. Which is good, not least because the maximum possible unsupported roof span will be a lot smaller than on Earth.

Re: EE 'Doc' Smith? Larry Niven?

Same thing. OK, EE was before genetic engineering was on the horizon, so no new body plan. But if you were picking human colonists for a high-G world, you'd select the shortest and most heavily muscled humans you could find. I confidently predict that if the colony survived, the fifth-generation children would be shorter still, more heavily muscled, with denser bone structure, and bigger feet for stability. Think Hobbit weightlifters in this case.

Re: EE 'Doc' Smith? Larry Niven?

The Valerian colonists were huge and powerful ...

Showing an inability to understand basic physics (and Darwinian evolution). The larger a structure, the less able it is to resist gravity. A flea can survive hundreds (thousands? ) of self-inflicted gravities every time it jumps. A mouse can fall off a cliff and run away at the bottom, unharmed. A human being over seven foot tall is freakish, and at a clear evolutionary disadvantage. (Much more likely to break bones when he falls over, for starters).

Inhabitants of high-G worlds will be small by Earth standards. Rugged and powerfully muscled for their size, certainly, but above all sufficiently small as to be able to resist gravity.

Also unlikely to be bipedal, unless their nerves and reactions are much faster than ours. The consequences of falling over in high-G are greater, and the time available to avoid doing so is much less. Think small thick-set centaurs or wallabies.

Apple to ditch Intel – report

Re: Different corcumstances

A while ago when AMD was causing Intel serious pain, ISTR Intel sued AMD for various IP infringements. I don't recall the resolution. Did it fizzle or get settled out of court, once Intel competed its way beyond AMD in the server arena?

My theory is that Intel needs AMD, to avoid being treated in law as a monopoly, and to keep itself at the sharp edge. AMD is now weak, and maybe Intel is cutting it some considerable slack with respect to other possible lawsuits? Not least to make it undesirable as a takeover target?

I'm speculating. However, I really don't think Intel would like to see AMD either go bust or taken over.

Re: using his product ...

He doesn't have the power Jobs had, either. If a majority of the Linux community felt that Linus was a hinderance rather than a help, there would be nothing to stop them breaking away.

There's a lesson there for the wider world. Dictators are bad because they can issue orders and punish those who disobey. A "benevolent dictator for life" in open-source software can only issue suggestions and justifications. Anyone and everyone is free to ignore him. In general they don't until the dictator ceases to be benevolent, because it's much harder going on the outside of the fold.

Open-source projects are probably the closest thing to a working system of anarchy that we'll ever see.

Re: Speaking as a printer engineer....

I thought that species was extinct (or mutated into big photocopier/ printer/ stapler/ puncher/ folder/ scanner/ shredder/ firestarter/ Allin1-and-a-bit engineer).

It must mean that there are places which still have one huge expensive printer for an entire building, which sooner (or occasionally later) will be unfixably broken and in need of replacement costing a five-figure sum because the breakage was caused by a luser sticking part of his anatomy in a place it shouldn't have gone. (The more highly paid an employee, the bigger the luser -- just as per the story).

Dinosaurs?

Think what replaced the dinosaurs. Proto-rats. Try lots of expendable printers. Not really cheap ones, their engineering is crap and the ink or toner is ultra-expensive. Really cheap printers are Xmas gifts for people you hate. But cheap enough that there's plenty of them on the network around the workplace, and no need for crisis management or expensive service contracts when one of them expires. Just heave it into the skip and buy another out of the toner and paper budget, when your friendly non-BOFH can't fix it by staring at its innards and employing a few more brain cells than the average luser.

Zopa is a great idea but you are playing on a field tilted against you. Put your money in a bank, and the government guarantees you'll get it all back, even if the UK economy tanks and many people that the bank has lent your money to default on their loans. Also the bank is too big to fail, so it makes reckless loans and drives loan rates down, knowing it cannot go bust. Bankers! Lend your money through Zopa, and you are on your own. Yes, you get more interest, but personally I don't believe you get enough to compensate for the risk to your capital, especially after it's taxed.

Silly question of the day: if the government takes 40% of your interest in tax, shouldn't it reimburse 40% of your losses if things later turn sour? :-(

Batch processing

Batch processing has considerable advantages. You have large-scale commit rather than small-scale commit. The batch is either processed in its entirety, or not at all. (Or at least, if it's being done right, that's how it should be).

That ought to make disaster-recovery easier, which is why the RBS fiasco was so shocking. Not only was there a loss of service for some considerable number of days, but it became clear there was also a loss of data integrity in the case of some customers' accounts.

Best of both worlds?

If you never use more than 32Gb this drive will behave like an SSD, because everything you store will be cached in the solid-state part. The difference is that you won't run out should you want to store more. The stuff that you store and subsequently don't refer to for a long time will "disappear" into the magnetic disk. The stuff that is active will be solid-state cached.

Should be the best of both worlds.

Especially if it can tolerate complete failure of the flash cache, and revert to being a magnetic-only disk. Anyone know? The failure mode of solid-state memory is reportedly often to stop working in a flash (sorry). Magnetic disks can also fail like that, but more often degrade progressively and gracefully giving plenty of time to copy your data elsewhere.

Re: So they will be paying you then?

Ever heard of the common good?

It might be a good idea for the mobile company to offer you a femtocell in exchange for a refundable deposit. On the other hand if it costs £50, I'd happily pay that for my convenience, and extend the convenience to anyone else with a phone in or very close to my premises. Administering a refundable £50 deposit might actually cost more.

Doing so for phone calls and texts has effectively zero cost. A phone call is 24 kbit/sec before compression, compared to 2 Mbit/sec on the poxiest of broadbands. A data throttle on "my" cell would be appreciated, so my internet doesn't get flooded by people downloading movies to their smartphones.

Re: Get one at home?

Actually the fact that you are registering the phones does create some degree of legal liability for you, if only for the act of registering them.

If the box just DHCP'ed, connected back to the mobile operator via a preconfigured encrypted VPN, and then accepted any phone in range, then you'd be acting as a carrier (for encrypted traffic that you can't even read) and all liability would be back with the mobile operator who could remote-control "your" (their!) femtocell.

I don't know if one can get a plug-in-and-forget box such as I've described above. I can think of a few basements where a cheap box of this nature would be very welcome!

Re: Don't tempt fate

I believe that at Krakatoa, what happened wasn't much dependant on the lava type. The ocean got into a (half-?) empty magma reservoir, and the result was possibly the biggest steam explosion that humanity has ever seen. (Unless Santorini was bigger).

True, if it's the highly fluid lava they get on Hawaii, the chances of the ocean finding its way into a large empy magma chamber are lessened.

Katla also isn't particularly explosive. Just high enough in toxic fluorides to poison cattle in Ireland, and acid enough to cause severe respiratory distress in London. It also upsets the climate, though not as badly as Tambora did. EjaFyallawhatever was a small forewarning of what's long overdue from Katla.

Re: Perhaps it's time for other hardware manufacturers to seek another O/S.

Android IS Linux under its skin.

As for why Google might ever do "Desktop Android for Business" ... certainly not to give the penguin a helping hand. It would be because they thought businesses were looking for something that could replace MS Windows and MS Office, and they thought that they could make a profit out of supplying it. Odds: 3:1?

IBM is the other giant with the means to take on the MS desktop stranglehold. Whether they have a motivation is quite another matter. They don't sell desktop hardware (having sold the Thinkpad business to Lenovo).

Re: MS Hardware

I never had much joy with MS keyboards. They felt "wrong", and that's before they started going glitchy after a couple of years (non-entries and double-entries). Low-end Logitech keyboards, on the other hand, are the best you can buy for little money. I actually prefer the cheap ones to some of their expensive ones that I've tried, and they seem to last very well.

I agree, MS mice are as good as Logitech ones, and both beat the rest hands-down. The choice mostly boils down to whether you like your mice fat (MS) or thin (Logitech).

Re: Not new...

Maybe they took the opportunity to test EMPs as well.

What was well-reported was the use of carbon monofilament wires to short-circuit electricity transmission lines. That was extremely effective. it's amazing how much electricity a carbon-fibre wire can pass before it gets hot enough to turn into CO2. The resulting spikes and surges on the electricity grid may well have been mistaken for EMP activity.

I have no idea what WW3 will be fought with, but I'm sure WW4 will be fought with stones.

Re: These People Are Nuts

Actually long-term stable climate is the norm, for most of the last few hundred million years.

The trouble is, it's a state that we don't want ever to see. No sea-level ice anywhere on the planet, and far too hot for large warm-blooded creatures like humans. The stability is created by cloud cover. It gets hotter, more water evaporates, more clouds form, more sunlight is reflected into space. Negative feedback (up to the point where the cloud cover reaches 100% and global warming soars to Venusian levels, which will happen in another few hundred million years because our Sun is getting older and hotter.)

Ice, on the other hand, creates instability: it's cold that creates more ice, which reflects more sunlight .... but it also traps methane, which causes rapid global warming should the ice ever melt .... We live in that least stable of global climates, an interglacial era between ice-ages. Once upon a time, just before multicellular life evolved, the global cooling ran away and the whole earth became a snowball. It's probably a good thing that the sun is now a bit older! Though the difficulty of surviving under a kilometer of ice might have been the trigger that got multicellular life started in the first place.

But if we over-do it, the ice goes away altogether, and that's also a bad thing.

We don't know what we're doing. We're trampling on an unstable natural system. The one thing we can be sure of is than an interglacial period is a global climate system NOT in long-term stable equilibrium. "Stable" is either an ice age, or an ice-free planet. One is too cold for humanity, and the other is too hot.

Microsoft then blew more holes in it to make Windows 2000 and yet more to make XP. It wasn't until XP SP1 that they realized Cutler had probably been right.

Some of us are still maintaining systems running NT or 98. Even 3.11 and MS-DOS 6.22 sometimes.

The usual scenario is that someone buys a piece of lab kit for £100,000 that came with a £1000 computer. The lab kit is still fine and dandy, and the computer interface works as well as it ever did. Up to the day that the computer expires. Sometimes, it's embedded so well they didn't even realize there's an ancient PC inside. (Screwed to metal brackets with self-tapping screws!)

At this point the manufacturer quotes you £100,000 for a new instrument that's so much better than your old one (but £98,000 more than you can afford). Or, £5000 for a "new" antique computer and an engineer to install it (plus labour and travelling time). That's if the manufacturer is still in business.

Cue a call to the IT geek, who hoards old computers ... with good reason. And yes, he's also hoarded a copy of the disk with the software installed on it. So easy these days ... 40Mb disk? 10Mb disk? But try finding a replacement disk small enough to replace it with!
