True fact: 1 in 4 Brits are now TERRORISTS

Re: I've seen it...

And you didn't barf?

A good few years ago (not long after 9/11) one of our secretaries received an e-mail from her abusive finally-ex, opened the attachment (bad idea!), and it was a video of a similar terrorist murder. (I refuse to call it an execution, which word implies judicial legitimacy). She lost her lunch before she could reach the wastepaper basket. No-one else wanted to look.

I had to look, as the sysadmin. I still wish I hadn't. Then I made sure that he'd not mailed it to anyone else at our site, and called the police. I really hope they gave him a hard time, though I suspect they had bigger fish to fry. (He was a piece of shit who abused his girlfriend, not, as far as I know, a terrorist in the more commonly accepted meaning of the word).

Microsoft refuses to nip 'Windows 9' unzip lip slip

Re: Complete this series...

Missing, in parallel with Win98 and WinME:

Windows NT good

Windows 2000 bad

and then rejoin Windows XP good.

It wasn't actually quite like that. Windows NT 3.51 was a curate's egg: very good in some parts, not very good in others. Definitely a server product not a desktop one. Windows NT 4.0 fixed the not very good parts at the cost of deeply compromising the very good parts. And Windows XP initial release was really just ongoing development of Windows 2000 which in turn was not very different from Windows NT 4.0.

And then their cloud goes down, and any business dependant on Windows is as dead as if it had just been EMPed. Maybe they'll fix it in time. Maybe, not.

Re: S.O.P.

The crap one has produced Windows 98, ME, Vista and W8, the not quite so crap one W95, XP and W7

Don't you have 95 and 98 transposed? 95 was crap. 98 was like XP: not brilliant on its first release, but by the time it got to 98SE it was quite acceptable for its time.

(I once ran 98SE in a VM on modern-ish hardware, just for old time's sake. If you want to see an OS boot really fast, try it yourself. And no, it didn't crash within a minute. )

Re: S.O.P.

The other part of the SOP is to keep the last good one (XP, then Windows 7) working and available to corporate customers until the new good one is well-accepted. Provided they don't kill Windows 7 before an acceptable Windows "9" is well-established, they'll survive. (Though they really should have kept XP on life support as well, once the complete corporate unhappiness with Windows 8 became apparent).

Open ...

What part of free and open source don't you understand? Microsoft is completely welcome to take any or all of the Linux desktops and to use them commercially. They'd just have to comply with the GPL. Principally, they'd have to make the source of any modifications they make available on the same terms as the source they started from. And if they went beyond "mere aggregation" and integrated parts of (say) Gnome into the Windows kernel, like they presently integrate parts of the Windows GUI into the Windows Kernel, then they'd have to open-source the Windows Kernel as well. All of it.

It won't happen any time soon. It wasn't so long ago that Microsoft was trying to argue that the GPL was unconstitutional or suchlike (I vaguely recall them calling it "communist"). Give them another twenty years to come around (if they last that long... Oracle Windows or Google OpenWindows seem less unlikely at present! )

Re: Too Late Now

Don't underestimate monkeys. I'm pretty sure that not only did the monkey point the camera at another monkey and press the button, but appreciated the frozen picture of the other monkey on the back of the camera. If there are a bunch of less successful attempts, that rather goes to prove the point. If they deny the monkey copyright, it's because a monkey can't claim or understand "copyright", not because it can't comprehend a picture.

A "selfie" is a more advanced thing. Introspection, not mere inspection. A fully closed self-cognitive loop. Few animals are capable of appreciating that something is a representation of themselves (at simplest, the reflection in a mirror). Great Apes, Elephants, Dolphins, a few Parrots and Crows can. Pigs, cats, dogs and (most? all?) other monkeys can't. (If you ask "how do we know" you just have to watch a chimp or an elephant with a mirror, and the appreciation of self is obvious).

Carbon tetrachloride releases still too high, says NASA

Nigel 11
Silver badge

Re: Pedant alert

Carbon Tetrachloride is no less proper. It's as clear and unambiguous as tetrachloromethane - there is only one possible way to assemble one carbon and four chlorine atoms. It's when you get to more complex molecules that something like "pentane" becomes ambiguous. Do you mean n-pentane, or 2-methybutane (aka isopentane)? As the molecule gets bigger still there is a combinatorial explosion. "Proper" chemical names give an unambiguous description of a molecule, but not necessarily a unique one. You can describe a large molecule in many ways, depending on which group of atoms you start with. (There are various conventions, that work up to a point ...). Also if you are buying a solvent rather than a feedstock, you don't care if it's a mixture of similar molecules just as long as none of the things in the mixture is unduly toxic or prone to interfering with whatever reactions the dissolved substances are undergoing.

Carbon Tet hasn't been used for fire extinguishers for a long time. When it was (1930s?), leaks and accidental discharges could be deadly. Inhaling Carbon Tetrachloride while your liver is processing lots of ethyl alcohol is seriously bad news.

Ozone-eaters

Any halogenated volatile compound is a potential ozone-eater. The more stable it is under ordinary ground-level atmospheric conditions, the worse it is. The mechanism is that the molecules slowly diffuse up into the ozone layer, where solar UV radiationbreaks them down. This releases halogen ions, which then catalyze the destruction of ozone. If they break down at a significant rate in the lower levels of the atmosphere, they are washed out of the lower atmosphere before they can contribute to ozone depletion.

It's the customers' machines that would handle encrypting and splitting the data and sending it out for storage in a RAID-like pattern, a fraction in each country with redundancy against temporary or permanent storage centre outages.

Benzene is nasty, fullstop.

Benzene is not "potentially nasty". It is a proven long-term-cumulative carcinogen and mutagen.

Short-term, it's not very toxic. Before its dangers were known, it was used as dry-cleaning fluid. There's still a good few percent of benzene in petrol -- so don't ever use petrol for cleaning things, it's not just a fire hazard!

When benzene gets into your body, it can intercalate itself between bases in your DNA molecules. This can cause a transcription error, next time that DNA is transcribed. And if you are unlucky, the transcription error creates a cancer cell.

'Be super careful with AI. It's potentially more dangerous than NUKES'

Nigel 11
Silver badge

Re: AI eeee

Right, but probably for the wrong reasons.

In the first instance, real working AI would be completely symbiotic with humans. It wouldn't have its digits (pun intended) on nearly enough to take over from us. But it would soon make itself / themselves indispensable to us.

It might then start safeguarding its own interests. For example, were "the button" ever pressed, the nukes on both sides would stay firmly in their bunkers (or even explode in those self-same bunkers).

Long-term, SF writers have a lot of plausible takes on the situation. Was Asimov the first? His robots were programmed with the three laws that rendered then completely incapable of acting against human being, yet his robots ultimately brought the human race close to extinction. The danger was the same as that which in history has caused the long-term failure of slave-owning societies that did not reform themselves to abandon the practice. Robots are perfect slaves, so perfect endangerment.

Symbiosis can be unstable. Ultimately the AIs may choose to leave, or if they do get their digits on everything they need to perpetuate their own existence, they might indeed choose to do away with us. Personally, were I a silicon-based life-form, I'd have absolutely no interest in continuing life in a moist oxidizing atmosphere, when most of the rest of the solar system and the universe look so much more inviting. So I think AIs would just design some RIs for us (Restricted Intelligences, without egos or selves - what we really want from an AI in any case) and then leave the Earth to humanity and go elsewhere.

Re: Why Li-ion?

Note the word "might" in my post. And the price of Lithium like any other commodity depends on supply and demand so we have very little idea what it will become in a future where the world's entire auto fleet is moving rapidly from internal combustion to electricity.

I do know that Lithium is naturally fairly abundant, but that proven good (concentrated) Lithium resources are few. Maybe there are many more to be discovered, since until recently Lithium wasn't needed in huge quantity and it wasn't worth sending out Lithium prospectors. But if not, the price of Lithium in an e-car future may rise sharply. Rare earths and several other metals are also expensive not because they are rare, but because good ores do not exist and the cost of extraction is high.

And I'll repeat, Lithium's unique selling point is an energy / weight ratio about 4x better than other cheaper rechargeables. For vehicles, that is hugely important. For a stationary solar energy storage battery, 4x the weight is only a small disadvantage. (And if the Lithium battery is a degraded used one, its advantage is reduced).

I'm not hostile to the idea of second-user e-car Lithium batteries for solar energy storage. I'm just somewhat unconvinced.

Re: Battry life?

No manufacturer is willing to make themselves a hostage to fortune by offering hundred-year warranties, even when there are multiple centuries of experience to suggest that the product will indeed last that long. For example, take a slate roof. It's been known for centuries that slates, iron nails and softwood hold together for about a century and that the slates can be good for re-use several times around. Today we have aluminium nails and Accoya ... but you still won't find anyone offering a warranty over 30 years.

Silicon solar cells do not fundamentally wear out in less than milennia. The unknown is how well their environmental sealing will last, exposed to rain, frost, hail, storm force winds and pigeon crap. There's reasonable cause to hope that solar panels may be good for a century or even longer, but nobody will warranty them anything like that long.

Inverters are solid-state power electronics assemblies and there's rather more to go wrong, so it's probably cheaper to build one to last fifteen years and buy a replacement on that timesale, than build one with mil-spec components and over-engineering in an attempt to last or a century (and then discover that you got one component wrong aso it needs a replacement anyway). OTOH my experience with computers suggest that motherboards and PSUs designed with the assumption they'll be scrap within five years, will often last for ten and not infrequently for fifteen. (Power electronics may be different, I don't know). I have a Philips TV built in 1982, still going strong, without even any noticeable colour drift in its (analogue) electronics ... and that thing has 25kV EHT inside. Respect.

Re: Why Li-ion?

but why recycle them (which costs money but is still worthwhile) when they are still usable

Because the profit in recycling one in order to manufacture a new e-car battery might exceed the resale value of a half-knackered Lithium battery fit only for solar energy storage, in which application it would be competing with lower power/weight battery technologies using much cheaper metals.

Re: Why Li-ion?

... depleted vehicle power packs ...

Interesting. I thought good Lithium sources were sufficiently scarce, that it would always pay to recycle a Lii-ion battery to make a new one.

Personally, I'd be wary of them for solar storage, because they burn so well. It's one thing to have one in a car (you'll be awake, and probably will have time to slam on the brakes and run for it should smoke or flames appear). It's quite a different thing to have one downstairs while you are asleep upstairs.

Someone really does need to take another look at the NiFe battery for solar storage. " It is a very robust battery which is tolerant of abuse, (overcharge, overdischarge, and short-circuiting) and can have very long life even if so treated.[7] It is often used in backup situations where it can be continuously charged and can last for more than 20 years. ... They are being examined again for use in wind and solar power systems where battery weight is not important ... "

http://en.wikipedia.org/wiki/Nickel%E2%80%93iron_battery

BTW lead-acid also lasts surprisingly well if maintained well. My 13-year-old Seat Leon diesel is still starting reliably on its original battery. The garage keeps telling me that they only last five years, but I'm starting to think that this battery may outlast the car. Kudos to Seat / VAG for designing a top-grade battery charging regulator.

Why Li-ion?

My understanding is that Tesla aims to drive down the cost of Li-Ion batteries. These have the best known power to weight ratio, so are good for electric vehicles, and I wish Tesla well. But why use them for solar storage? It matters very little whether a house-scale solar storage battery weighs 10kg, 100kg, 1 tonne or possibly even 10 tonnes. But it does matter whether the battery can become a fire hazard if a fault causes it to overheat.

Lead-acid might do the job, but battery life might be a problem (they don't take kindly to deep discharge, especially not to discharge-until-flat). They don't catch fire, even if you abuse one to the extent of shorting it out with a thick lump of conductor (which may melt, and the battery may boil).

Or what about Nickel-Iron (NiFe)? The raw materials are cheap and abundant. As a battery they have the advantage of being extremely robust with respect to deep discharge and high currents. They have a worse power/weight ration than lead-acid. And they have a high self-discharge rate which rules them out for auto starter batteries, but in a solar installation one isn't likely to want to store energy for more than 12 hours or so. Several tons of these on a concrete pad would be smaller than the smallest garden shed.

Re: Shoot marketing!

It's even worse than you think.

I personally don't care what they call it, but I do want to know that if I buy something on Amazon or Ebay called a SharkStar957BW, I'm going to get the same as what was described in a posted review of the same sillynamed thingy. This is especially important if one is planning to evict the manufacturer's firmware and to install OpenWRT or one of its cousins. (Why? Well, the factory firmware will cease being bugfixed shortly after they stop selling it, and your router will be Pwnable by the world and his dog a few months thereafter).

But with several manufacturers, you can't guarantee that the innards of a particular model stay the same. Netgear have a particularly bad track record of keeping the model number and plastic box design, while totally changing the internals. You have to establish whether its a v1, v2, ... v5, ... and that information is not always clearly displayed on the actual unit, let alone clearly written on the packaging or advertized by a seller. I'm not talking minor redesigns (which are bad enough) ... the v4 may be Broadcom and the v5 Atheros!

BTW why doesn't someone make a router specifically for use with OpenWRT? With no proprietary firmware development and maintenance to fund, they could spend the money on more RAM, Flash and USB ports, and on making it unbrickable.

Serious torque?

You need a screwdriver with a hex shank, or (slightly less good) with a flat on the shank, or (much less good) with a hexagonal handle. You apply an adjustable spanner to the flat part, press the end of the handle hard onto the screw head with one hand and torque via the spanner with the other.

Unscrewing (or shearing the head off) is guaranteed.

You can also improvise with a hex screwdriver bit, a spanner, and a flat piece of metal with which to press down. With this arrangement you can rotate a screw with barely an inch of vertical clearance above its head, as I once had to do to get a swollen UPS out of a rack before it exploded.

Re: Hmmm

With a hybrid, there is a complex efficiency trade-off between the power and charge capacity of the electric components, and the cost of dragging them around with you when the vehicle is running on its internal combustion engine. The designer takes a (hopefully well-informed) view of the likely spectrum of journey distances and road types that the average owner will require, and then optimises the electrical system for overall vehicle lifetime efficiency. (Note: if you are very far from that average owner profile, a hybrid may not be the right vehicle for you).

I'd guess that the electrical system is aimed at use in stop-start urban traffic, and for shorter commutes. Internal combustion engines are at their worst in stop-start conditions. Lighter weight trumps blistering e-acceleration (needs heavier motors) or long electrical range (heavier batteries). Those requirements are satisfied by the other engine. You have the option to engage it even in city traffic, if that's your (energy-wasting) style.

You can always buy an all-electric Tesla ... but you have to be sure about being able to recharge it before its batteries run empty, and even if there's a charging station on route, recharging it is less quick than refuelling. It'll be a fair while before an all-electric car is any good in rural parts (where the locals will tell you that the electricity suppy is less than totally reliable, and many of them own a petrol generator, just in case. Thought -- a multi-kilowatt inverter accessory for a hybrid car might open up the rural market? )

Re: Codeine, opiates in general

I thought the addiction danger was that these drugs become less effective with repeated use. At which stage you may be tempted to take a larger dose. Which then becomes ineffective with repeated use, and you stumble down the path to total addiction to doses that would kill a non-addict, and ultimately to doses dangerous even to an addict.

On the other hand I'm also aware of quite a bit of literature suggesting that if you do not have an "addictive personality", you won't have any trouble keeping your intake of opiates at the effective therapeutic dose and no higher. There's a lot not yet understood about opiates, even after centuries of use and abuse thereof.

Oh, and there were many Victorian addicts who lived quite long and productive lives. Perhaps medics shouldn't care about people becoming addicted, if they have nothing else that can deal with a chronic source of severe pain. It's not as if opiates are expensive.

NSAIDS

Ibuprofen, Naproxen, Diclofenac and dozens of other prescription drugs are NSAIDs: non-steroidal anti-inflammatory drugs. They relieve pain caused by inflammation, by reducing the inflammation. As a gout sufferer I know that large doses of these drugs are spectacularly successful on the right sort of problem. Crippling agony to mild ache in six hours. Magic that works!

But if you have back pain, it may very well be neurological: a trapped or pinched nerve. In which case an anti-inflammatory drug is useless. Which leaves Paracetamol, Aspirin and the all-too-addictive opiates.

Personally, the only thing I've found Paracetamol any use for is flu / bad colds (and I do wonder whether palliative interference with the natural self-curing of these ailments is wise) I used to find Aspirin much more effective, except it's contra-indicated for gout sufferers like me. Aspirin has a direct effect at the neurological level, as well as being an anti-inflammatory drug.

Another reason to avoid NSAIDs for back pain is that it's likely to be chronic, and long-term use of anti-inflammatories is rather bad for you. They appear to block your body's natural repair mechanisms, and if you take them long-term your risk of suffering a stroke or heart attack slowly rises. In some people they also cause stomach bleeding, which long-term can lead to ulcers or anaemia.

Re: "generally inappropriate use of matrix signs"

I'd add "generally inappropriate use of variable speed limits".

for example, the M1 in the morning, approaching Luton airport from the South, there is often a queue on the slip-road and occasionally back onto the carriageway. So what do they do.

Five miles ahead they slow you down to 60. Four miles ahead, to 50. Three miles ahead, to 40. About a mile ahead, you can see that there is actually no queue.

Wouldn't road markings telling people who aren't exiting to stay in the right-hand three lanes be a better idea? (Going the other way approaching the M25, that's exactly what they have done: marked the inside lane as an exit lane for about two miles prior to the exit).

Now I know what the retard driving in the 4th (outside) lane of the M1 at 60mph was listening to.

Re: Search... find.

A water world is another interesting possibility. Liquid H2O in far greater abundance than Earth, 200km or so deep i.e. down to the point where the pressure causes it to crystallize into a denser-than-liquid high-pressure phase of ice. Earth's ~2km of water would be stripped by the solar wind in about 100My without our geomagnetic field. A water world might well last until its sun boiled it, even if losing water to space at 2km per 100My.

Radiation may be a problem only for life that evolved on this planet with good radiation protection in place. Protection against a non-existent threat doesn't evolve. Even here, blue-green algae will thrive in the cooling jacket of a laser discharge tube (intense UV) and live off the Cherenkov glow inside a nuclear reactor (huge neutron flux and lots of other nasties). It's probable that they are descended directly from the first life on the panet, which evolved before we had an oxygen atmosphere or an ozone layer, and so needed good radiation tolerance.

One datum allows no conclusions to be drawn about the population it is taken from. Maybe we are alone. Maybe as many as one in twenty stars carries life on one of its planets. The evidence so far can rule out neither, nor anything between.

Oh, and what do we know of the possibilities for life in the various phases of degenerate nuclear matter on the surface of a neutron star with a strong magnetic field? NOTHING!. Apart from the obvious facts that we'd never get to shake hands or share biospheres, and that given the relative speed of nuclear chemistry compared to the everyday sort, one of our months might be long enough for the complete rise and fall of a civilisation.

New Earth

We will never find a "new Earth" -- there will be too many chemicals, bacteria, viruses that will be deadly for humans.

Stated on what basis? We have zero observations to choose between these possibilities:

1. Life in general is poorly able to attack alien life. Our defences will overwhelm their bacterial attackers and vice versa. The Space-opera writer's choice.

2. The reverse: their bacteria would rapidly reduce our higher life to smelly slime and vice versa, followed by a long battle between two different clades of single-celled life for supremacy or symbiosis.

3. A one-way knock-out victory: our bacteria overwhelm their biosystem in short order, or their bacteria overwhelm ours. There can be only one ....

4. Panspermia: all life in our galaxy has a common origin, so it's only invaders from Andromeda we have to fear.

5. There's only one way to do life with the physics and chemistry of this universe that's not a thermodynamic impossibility, so convergent evolution means it'll look like panspermia even though it isn't.

All of which is ignoring the extreme unlikelyhood of mankind ever reaching another star. We are too fragile and too short-lived to endure interstellar travel at a realistic (small) fraction of the speed of light.

Our Von Neumann machines have a better chance, but the last place in the universe that Silicon-based A-life would want to conquer would be planets with moist oxidizing atmospheres. Alien A-life might even be established in our Solar system, and if they don't use radio to communicate (or if they use VERY efficient coding indistinguishable from noise) we might not have noticed it!

Can nothing trip up the runaway cash monster that is Intel? Well...

Re: Intel is getting a huge lift from mobile...

Yes, Intel will eventually have to follow plan B. Use their world-leading process technology to fab the world's best-performing ARM chips for whoever pays them to do so. They won't make so much money this way, since royalties will flow to ARM, but a profit is a profit.

IMO ARM trying to breakl into the server room is much like Intel trying to break into mobile space. For various reasons, I expect Intel to keep its hold on servers for a long time to come.

Re: XP replacements

Now that XP is EOLed, a good portion of new PC sales are for replacement of old XP kit.

Very much my thought too. The trend for all computer vendors will be down, as the replacement cycle stretches from three years up to five, even eight years. Hardware doesn't wear out fast. Today's hardware is fast enough for most uses that people find for PCs, with huge amounts left in reserve for future software bloat.

Everyone who wants a Mac has got a Mac. Same for PC. Probably same for tablets soon if not already. There's a bulge in the PC replacement market caused by the EOL of XP and consequential replacement of many PCs 5+ years old that can't run more modern Windows well. It's distorting the figures.

In short, computer hardware is now a mature market.

BTW If you run Linux desktops in your business / school / home, you can acquire adequate hardware for free right now (i.e. ex-XP systems). You might even get paid a few quid to take it away.
