Re: "a parasite that's so successful it's killing its host"
A successful parasite doesn't kill its host. In fact the greatest success is to become a symbiote, such that the host cannot survive without the (former) parasite.
Methinnks I've just over-extended the analogy.
You must have an enlightened employer with good fire sprinkler coverage.
Often, between health-and-safety and tidy-minded managers, this practice is banned. Health and safety do have a point - large amounts of vertical paper will make a fire spread faster. As for the managers, "a tidy mind is an empty mind" and they are the un-dead proof.
Floor boxes - don't get me started
Oh yes, floor boxes, the most moronic architectural fad since Le Corbusier decided ugly was beautiful and concrete chairs were comfortable. But a lot more dangerous.
They're supposed to be "flexible". That means, you might be able to have them moved, if you have a large stock of spare matching carpet tiles, can afford to employ a carpet fitter, and an electrician, and a network technician. You may also need to replace the entire cat-5e or fiber run, if the original installer didn't think to leave a couple of meters of spare length under the floor in case the box needed moving a few feet.
In practice the furniture gets moved, the boxes don't, and cables are left trailing across the floor under people's feet and wheely-chair wheels. When cat-5e fly-leads get crushed, data unreliability results. Worse, when mains cables get crushed, a fire or shock hazard results. I have seen more than one instance where the insulation was melting because the underlying copper was fractured, and others where live copper was exposed. And of course there's the trip hazard. Get a cable caught around your ankle, and if you are lucky you get a sprain that develops into arthritis during your retirement and puts you in a wheelchair in your 80s. If you are unlucky you trip, bang your head on the corner of someone's desk, and are dead or a vegetable an hour later.
And when the much maligned Health and safety people spot the hazard and insist that the floor box is moved, the architect-types then tell you that it's impossible to get the box within two feet of this or that wall or pillar, so you discover that several square meters of expensive office space are effectvely unusable.
All of which happens after the architect has won some sort of award for a beautiful expanse of carpet tiles and unused desks uncluttered by visible sockets, and has moved on to fuck up someone else's workplace.
Seeing the centre of our galaxy clearly is much harder than if we had a view "down" on it. Obviously distrance restricts resolution, but there will be a lot less dust in the way if we can look "down" on some other galaxy, rather than at the edge of its disk.
OTOH being *precisely* on the rotational axis of a disk surrounding a huge black hole might be extremely unhealthy. One can probably say that if there were another galaxy with its axis precisely aligned on us, we wouldn't be here to notice it.
Re: Slides don't surprise me
Why would you go into a phone shop if you wanted to avoid a sales rep?
To look at and handle some phones?
This might be part of their demise. Back when phones had buttons (and features rather than apps) touch and feel (and even sales-guidance) was important. Now they are all touch-slabs running Android(*), you don't need high-street outlets. Especially don't need high-street outlets not working for you (the phone network).
I knew what Android was like from friends who'd got a smartphone before I did. Choosing a phone was mostly down to internet reviews and simple parameters like size, weight, and (reviewer-compared) battery life. Then I bought through Amazon at lowest pricce, and it turned up the next day (with a user manual in Estonian, but what hey, nothing wrong with the phone).
(*) Yes I do know about iPhones and WinPhones. I just don't want one.
Re: Poor eyesight
An interesting case is people who need to enlarge something because of their poor eyesight. Use a magnifying glass, you say? That's not so good for piano music!
Actually, it probably is, unless the poorly sighted musician is also a wizard sight-reader, and has a very good page-turner to assist him. Mostly, musicians have memorized what's on the page a long time before they've perfected their performance, and the sheet music in front of them is more for reassurance than out of necessity. Some will perform without any paper at all.
Blind musicians don't have the paper option. It doesn't seem to impede them. I wonder, do they learn completely by ear from recordings, or do they need the help of a sighted teacher to learn a new work?
Mozart heard a secret papal mass - once! - as a child! - and then wrote down the entire score, note-perfect. But he was a genius.
Re: Copying & Printing
It's called fair usage. You're allowed to photocopy smallish exerpts of a book (from memory, no more than 10%), but not the whole book. Enforcement is usually informal, by means of the library's photo-copier. It typically costs 10p/page, some of which is fed back to book publishers although they can't know what was copied. That also discourages excessive copying: 400 pages at 10p/page is £40, and the majority of books cost less than that. And of course, if you use the copier for too long, the librarians will investigate what you are up to.
There's a HUGE loophole in that if you can borrow the book, you can copy it on some other scanner or copier! In my UG days, the publisher had allowed a recommended book to go out of print, and every student had an "illegal" copy.
It ought to be straightforward to link a dedicated terminal displaying a scanned book to a library printer, in such a way that fair usage rules are enforced.
I'n recent years I've taken to using my phone to photograph exerpts, rather than pay to use the library copier. Don't know what the rules say about that, but I feel it's fair. So far the librarians have ignored me. The copy is inferior. It's mainly a way for me to time-shift by study of the exerpt rather than anything that I want to keep long-term. (It occurs to me that taking photos of a screen is easier than taking photos of a paper page).
Re: the public was never in danger
Professional / Military grade non-detonating explosives are not particularly dangerous, and the greatest risk is probably the toxicity of heavily nitrated hydrocarbons. They need a detonator to make them go bang. If you manage to set them on fire, they do burn well, but probably less well than gasoline (and they're solid, not liquid).
I do wonder why the police used a significant amount of (presumably well-wrapped) explosive, rather than a minuscule smear, unwrapped. Both would give out the same concentration of vapour so they'd both smell the same to a dog. Maybe they were actually testing a scanner (which failed!), rather than training a dog,
Another SFplot element coming to reality
Queng Ho Localizers, here we come.
I first read Vernor Vinge's "A deepness in the sky" shortly after it was published, and this was the plot element I found hardest to believe in. And now, it's looking not just plausible, but achievable in the next decade or two.
Which should scare us. In the book, ubiquitous surveillance was described as the fastest way to kill a civilisation, and that's something which I found was not the least bit hard to believe in.
(Book strongly recommended to anyone who hasn't yet read it.)
Having a computer take over as many of the boring pre-flight checks as it has instrumentation to perform is likely to increase safety. A computer will do the same thing over and over again with almost 100% reliability. It won't ever get bored or distracted. Humans aren't like that. They tend to miss items from long checklists, and sometimes miss even a red flag if they're bored.
I agree about actually flying the plane, and the handling of critical situations in the air. In these cases, an experienced pilot's instincts are likely to work better than a computer following a completely fixed rule-set. It's a completely different situation to running through a checklist.
Re: Does it really matter who shot it down?
but that's like claiming that murdering the wrong man is only manslaughter, and doesn't wash for me.
In a war, that's not manslaughter, it's not even regarded as a crime. It's "collateral damage" provided one's intent was to hit the enemy, and the poor bloody civilians were just in the wrong place at the wrong time.
And so do conspiracy theories. Until there is hard evidence, I won't be attributing to malice(*) that which is adequately explained by incompetence.
(*) malice by the hapless incompetents in charge of the missiles, that is. Putin does have a lot to answer for, in terms of creating and prolonging the war, and in terms of putting those missiles in the hands of inadequately trained rebels.
Re: the “adult weight” of 87kg
Unless it's a RyanAir flight, where they fine you something silly for every extra ounce.
Re: tare weight...
Commuter flight. The smaller the plane, the more easily it can be unbalanced. One twenty-stone passenger at one end and two small children at the other are a significant imbalance, if the plane seats twenty rather than two hundred.
In passing, this is the real reason they'll upgrade economy class passengers to business-class if business-class isn't anywhere near full. A tail-heavy plane is unsafe. Passengers in business class are a necessity for safe operation!
If only they were carrying hundreds of tonnes of some sort of liquid that could be pumped into tanks in different parts of the aircraft to rebalance the weight.
The obvious problem with redistributing the fuel prior to take-off, is that for a flight destination close to the plane's maximum range, the tanks will all be close to full. Take-off and climbing to cruising altitude uses a significant fraction of the plane's fuel, after which optimally balancing the plane during the rest of the flight is part of normal operations.
And of course, you would need to have instrumentation on the plane's undercarriage to detect the loading problem. Halfway down the runway is too late to rebalance the fuel load.
If there is a problem detected what should they do? You need more procedures and to determine how to correct the weight distribution and the co-operation of the passengers.
This is the sort of thing that the plane's computer should do. Check the loading. Do nothing if it's within optimal operating parameters. Alert the crew if it's sub-optimal, so that they are forewarned and can decide whether other conditions (bad weather etc.) make it necessary cancel the take-off. And refuse the allow the plane to fly, whatever the crew might think, if it's so badly ourt of balance that attempting take-off is likely to be disastrous.
So the flight crew would get an orange light maybe one flight in twenty, and a red light once in a blue moon, and air travel would become slightly safer. What to tell the passengers if it's a red light? That the plane is unable to fly because of a red light that has to be investigated. If the problem is in the passenger distribution, that should be obvious to the flight attendants once they are told to look. I expect more often, it's in the cargo hold.
Not having any instrumentation so the problem can't be detected until the plane is halfway down the runway, is crazy. That may well be too late. One of these days, just when the pilot needs more thrust than usual, there will be an engine failure. Most disasters happen because too many things go wrong at once, not because just one thing fails.
Re: Seniors have their moments
It'll be a while yet. It's a hard problem, even for a human being. You'd need an AI at least as intelligent as a dog. How often do your ears prick up because you thought you heard your name? How many times have you had to ask someone to repeat what they just said? And then understood no better than the first time they said it?
That third one, not often, but I did once ask in Glasgow which platform the London train went from. The reply could have been any of the platforms on the station. I missed the train.
Boss: "You're fired!"
Victim: "Computer: Format C Colon. YES!"
What I wan to know
Is whether it can survive face-down 2m drops onto a flint-gravel drive?
There's the VM option (install VMWare Player, install Linux into a VM, treat Windows as the world's slowest bootloader). That depends on whether the CPU supports VMWare (do Intel still make any that don't?) and whether it has enough RAM.
Where does liability stop?
Intersting point here. If Samsung buys chips from Qualcomm in good faith and without knowing about the internals beyond the published literature, and if Qualcomm is allegedly infringing an NVidia patent within that chip, does that make Samsung liable? Especially, liable going back in time to before the allegation was even made?
If so, I'm slightly surprised that any large company is willing to buy VLSI subsystems from a small(er) company, and that patents haven't yet caused all progress on the hardware front to cease!
My first thought was that the tail isn't long enough to defend the neck, so all a (large) predator would have to do is get around the front and rip its throat out. (Proof, perhaps, that carnivorous dinosaurs did not hunt in teams? )
But then I remembered a film of Giraffes fighting ... I guess that the front end was maybe just as capable of being used in self-defense as the back end.
Re: Verifying the source of the data
Track, yes, if "anonymous" is not built in as an acceptable source. But how is that different to today's internet, or the telephone network? If a two-way communication is desired, then an outgoing packet has to have a truthful source. If verification was built in, you'd be able to know that the claimed source was untruthful, and 99% of the time the right action to take for a non-verifiable source will be to drop the packet.
Intercept, no. There is no conceivable way to prevent the data content of the packets being encrypted. By the way, one of the dual purposes of public-key cyphers is sender-verification. You can even do verifiable plaintext. (Transmit single-encrypted with your own private key, rather than double-encrypted with your own private key and your recipient's public key)
Might this be the DAP of networking?
Before LDAP there was DAP. As far as I know it was never actually fully implemented, let alone ever used on a large scale. It was so encumbered with features and misfeatures, that one might have expected it to sink without trace.
But someone took a knife to it to create Lightweight DAP and the rest is history. Maybe that history is about to repeat itself. Certainly, the limitations of the internet as it is today are becoming ever more apparent. Something better is needed!
Re: Is using Google proprietary APIs better than a RFC standard like IMAP?
Proprietary API normally means that the owner won't let anyone else know what they need to know in order to call the code, or to write a compatible library or server with the same API but a different codebase. For example, Microsoft's obfuscated calls in the WIN32 API which only MS Office was able to use (to make sure Office couldn't run under WINE), or Microsoft's very expensive (and eventually failed) battle with the EU to keep the fine details of its AD fileserver protocols secret and thereby keep Samba/CIFs from becoming a full competitor).
If Google has published the documentation of its new API and isn't trying to prevent other folks interfacing to it, it's not proprietary. It's just an alternative to IMAP that might become tomorrows standard, if it attacts sufficient interest. (Just as IMAP was once a fancy new alternative to POP).
Re: Odd List
Black, Blue, Great or Long-Tailed?
Re: Real coding!
Same reason we can't have decent filesystems (ext4 anyone ?) on USB sticks
As already stated ext works just fine on a USB stick, but Windows can't read it.
ntfs-3g on Linux has had write support for NTFS on Linux for quite some time. I'm not sure I'd trust my life to Linux writing reverse-engineered NTFS, but for read-only use it's never let me down, and my occasional forays into writing well-backed-up or disposable NT filesystems have also not failed in recent years.
Finally, KVM is now pretty solid, so you can invoke Windows in a Window under Linux, and access the Linux filesystems across the (virtual) network. Using free-beer VMware player you can do the same with Linux in a Windows window.
Another better question?
Another better question might be "where can I download your source from?", especially if you then really make sure that you can rebuild a working box from that source.
If you can't, it's either a GPL violation (let the copyleft owner know!), or use of the "mere aggregation" exception to tie you in to that particular vendor for support. Should they cease maintaining the software for the hardware you have come to depend on, you may be forced into an expensive hardware replacement for lack of a three-line patch to the bundled software.
These things are not like routers. It's rather more expensive and disruptive to have to junk and replace them if and when a never-to-be-fixed security problem is revealed.
Re: How about weapons designed for 3D printing?
I think the question is why try to make a gun barrel out of printed plastic, when machined metal is so much better (ie, so much less likely to blow the shooter's hand or face off, to say nothing of having rifling that's still there after the first shot).
I'm trying to think of any advantages a 3-D printer might give for the construction of bows or crossbows, but I can't think of any..
Re: Nearly a year of living with my 3d printer now
can i download and print something
That ought not to be missing the point (athough today, it probably is).
It ought to be able to download the CAD details for just about any plastic artefact, so that you can manufacture your own spare for any plastic widget or cover that gets broken. However, it's not in a product manufacturer's interests to make them available. They'd far rather we bought a whole new hairdryer or whatever. Some have even been known to build in weak spots to encourage things to break sometime after the warranty has run out.
Perhaps what is needed is a breakthrough in 3D scanners to parallel 3D printers, so you could just dump your broken pieces into a 3D scanner and then have the computer reassemble the details of a whole one and print it for you. No CAD expertise then needed.
Re: The wake?
Except it's going so darned fast, you don't have the time to do anything about it! Compare a ground-to-air missile which leaves a very obvious exhaust trail, but that doesn't much help what it's aimed at.
(More use as a torpedo than a submarine, though).
I've noticed a lot of russian words do seem very closely related to english ones and I've no idea why, it's almost as if russian and english are cognates but to my knowledge they're not.
English and Russian are both members of the Indo-European tree of languages. The common roots were several milennia back, but even so it's a lot more commonality than English and Chinese (or English and that linguists' puzzle, Basque).
Also, English has a huge vocabulary compared to most languages. It arose from a merger of Anglo-Saxon and Norman French ( themselves both hybrids). Since then, rather than jettisoning redundant words, it's been shuffling them to create subtle differences of meaning. So if there is a common Indo-European root for a Russian word, there's probably twice the chance that you'll recognise it in English (compared to, say, German or Spanish)

Re: knowing what you don't know
Ocean life produces small amounts of methyl chloride, larger amounts of methyl bromide, and huge amounts of methyl iodide. Also amounts of other halogenated hydrocarbons small compared to human production. Natural emissions of methyl iodide outweigh human emissions by at least one order of magnitude. (It's a major component of the "smell of the sea" that you can detect a few miles inland with a breeze from that direction).
Fortunately, methyl iodide has a shortish half-life in the ground-level atmosphere, because iodine would otherwise be a far more potent destroyer of ozone than chlorine.
Methyl iodide is an extremely potent greenhouse gas as well as an ozone eater. It's long been an evolutionary puzzle as to what it was that kept the Earth from freezing, back when the sun was young (so considerably cooler than today) and when the atmosphere did not contain oxygen. Methane and CO2 aren't thought to be sufficiently potent greenhouse gases for back then. My theory is lots of methyl iodide, stable in a reducing (methane, nitrogen, CO2) atmosphere. It's created by cyanobacteria in today's oceans, and they are amongst the most ancient and radiation-tolerant of life-forms, so why not the same back then? When they'd finally emitted enough photosynthetic oxygen to convert all the planet's near-surface Iron-II into Iron-III, the oxygen built up in the atmosphere, the methyl iodide levels dropped to today's low level, and (not coincidentally?) the "snowball earth" episode occurred. Which in turn seems to have driven the emergence of higher life-forms. But maybe that's the unlikely event, and a possible answer to the Fermi paradox - most other places, simple life drives itself to extinction when it finally converts its atmosphere to oxygen?
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.
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.
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).
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.
Re: Windows 7.1
Amen. If you've finally managed to get clean from Microsoft addiction, there's no way you'd ever want to go back. (But as with opiate addiction, getting clean is far harder than anyone ever admits).
Re: Windows OSaaS?
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. (Worst case, they discover that the cloud has come to depend on the cloud in a circular self-referential manner ... an SFnal apocalypse scenario that scares me more than nuclear war).
It may take a few more relatively small cloudbursts to drive the message home, but I don't see mission-critical SaaS ever catching on.
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. )
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).
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).
Re: The fact that the attack occured one day after MH370 disappeared...
