TSA to pull backscatter perv scanners from US airports

Re: For frequent flyers it

All frequent flyers should note that the (cosmic and solar) radiation dose from hours at 40,000ft considerably exceeds the radiation dose from a scanner. So those who are paranoid about radiation shouldn't fly frequently, if at all. BTW airlines avoid flying too close to the Earth's magnetic poles, not because it screws up compass navigation (which they don't routinely use these days), but because the radiation levels are far higher there than elsewhere during a solar storm.

The fact that aircrew don't have notably higher levels of illnesses that can be induced by radiation leads me to the conclusion that there is no significant risk to any passenger, even a frequent flyer.

There's also some research that suggests that low ionising radiation doses may be *better* for one's health than *very* low doses. Our immune systems may be evolved to deal with radiation up to the upper reaches of naturally-occurring levels (for example life above a naturally radioactive granite bedrock). It's hard to actually prove, since the statistical signals are very weak.

Intel: Everything is absolutely fab-u-lous, particularly in servers

Re: Ostrich Corp

IF it's still the Intel of old, I expect that they have a plan B. Remember when it looked as if AMD had stolen the server market from Intel? The Opteron outperformed the Xeon at virtually all levels, and on top of all that AMD invented the 64-bit X86-compatible CPUs.

But Intel came out on top, because they'd never actually stopped developing the Pentium-3 architecture. They'd just mostly stopped selling it. And when the P4 architecture disappointed, plan B came to the front.

Plan B today might be "if you can't beat them join them". Pay license fees to ARM for the CPU design, but use their fab technology to make the fastest lowest-wattage ARM cpus in the marketplace.

Only the paranoid survive ... but also every corporation that reaches the top has no-where to go but down, and usually doesn't know how to descend slowly and gracefully.

INTC stock is remarkably cheap. The bankers are writing them off ....

Lesson for UK to learn: scrap extradition treaty with USA

What happened in this case is almost certainly what would also have happened to gary McKinnon, had our home secretary not suffered a last-minute attack of commonsense.

the US "justice" system is designed so that prosecutors can and do put innocent people in jail for several years, because the alternative is something like risking incarceration for life with no prospect of ever being released. We should not extradite anyone to the USA, until a UK court is satisfied:

That there is prima facie evidence of a crime and of the accused person's guilt

That the correct jurisdiction to try the case is the USA not the UK

That the alleged "crime" is criminal under "natural justice" or UK law, as well as US law

And IMO, that the accused person is not and will not be threatened with any punishment that is in the opinion of a UK court, grossly excessive. Because that's how they persuade innocent men to plead guilty, or to kill themselves.

Security audit finds dev OUTSOURCED his JOB to China to goof off at work

Nigel 11
Silver badge

Lesson to be learned?

Perhaps the lesson to be learned is that outsourcing can work well, IF AND ONLY IF the project manager is a darned good programmer in his own right.

If he is, then it's quicker to do the desining and quality control oneself, and hive off the actual coding to sub-contractors on Chinese wages. They can't get bad code past him, and will soon know not to try. If they aren't up to scratch, they don't get any future work.

The usual outsourcing disaster starts with managers who make up for in arrogance what they lack in ability. The subcontractors soon work out that they can leave the coding to their weaker colleagues, improve their margins by skimping on the debugging, and so on. (Much the same thing if the coders are still in-house, of course). Also, since the manager can't code, the designing and specifying is also likely to be insane.

Re: GNOME 3

So don't use it. the time for shouting and screaming because they took away the familar Gnome 2 interface is gone. You can now have Mate (Gnome-2 derived, but moving to Gnome 3 libraries underneath), or Cinnamon (layered on Gnome-3 in the first place). Both are now stable enough to use. Both are close enough to desktops as we know them that no-one should be too unhappy.

You can also choose Scientific Linux or Centos 6.x which still use good old Gnome 2 and offer at least five years' future support thereof.

Linux

Don't forget Centos and Scientific Linux

To complete the distro-ology of the free Red-Hat flavour, you have to include Centos and Scientific Linux. These are both very close to the corresponding non-free RHEL version. Of the two, Centos tries very hard to be *exactly* the same as RHEL. Scientific Linux has a different kernel, but the differences are slight. Basically, if CERN needs it to do something that Red Hat don't support, then CERN patch their kernel.

As far as ordinary users are concerned, these are both almost identical to RHEL, and the most conservative option you can find. Rock-solid-stable, and still running Gnome-2. The latter is no bad thing, although I've made friends with Fedora + Cinnamon of late. I feel you can be more sure that SL will continue into the future than Centos, because CERN needs SL to stay working.

RHEL 7 is coming soon (months). It will be intersting to see whether CentOS ans/or SL are able to release their 7.0 within 2-3 months, or whether there will be more collateral damage as a result of Red Hat having to protect their commercial interests against Oracle.

BTW, for whoever was berating Fedora for not shipping with non-free software: Fedora is closely linked to Red Hat and therefore has to be VERY cautious when it comes to possible copyright infringement and lawsuits. There are repositories of all the non-free stuff that work well. You have to add them yourself, because Red Hat can't afford the risk even of shipping with them in place.

Re: Perhaps a Full Vacuum is the best Hard Drive environment then? (Patent Pending)

There's no way you could maintain a precisely defined tiny gap between the head on the end of a two-inch arm and the spinning disk in a vacuum. The head quite literally flies. It's the dynamics if the gas between the head and the disk that keeps it at the constanrt correct distance.

BTW what about Methane? It's about two-thirds the molecular weight of air (CH4 = 20, O2 = 32, N2 = 28), it's not prone to leaking through nano-pores like Helium is, it's not prone to reacting with metals like Hydrogen is, and although it's flammable it's hard to see how an HDA-full of methane could cause any sort of serious problem. Lighting a gas cooker burner probably lets more than an HDA-full out into the air and then deliberately sparks it.

Unfair contract terms are not enforcible

For far too long companies love to put clauses into their contracts which pretty much mean 'we can do anything we want to to, and if we amend you're contract, however detrimental it might be to you, you shall have no rights to complain or get out of the contract'.

Google "unfair contract terms".

Then tell your service provider that you consider whatever terms of the contract that they are using to increase your charges to be unfair (in the legal sense). Offer to continue to pay at the original rate. Tell them to take you to court if they won't accept that.

An RPI-linked increase is probably fair (if mentioned in the contract you signed). An increase caused by a new government regulation might be fair, if they can justify that the increase is merely passing on increased costs imposed on them. I very much doubt that anything else would hold up in court. Most people are too easily intimidated!

What's an unpleasant but passing experience for most of us, is not so for the infirm or the elderly whom this bug can kill. Incidentally one of the vulnerable groups is people being treated for cancer. Chemotherapy weakens one's immune system.

Don't forget Neville Mott

I've always thiought that the real father of the Field-Effect transistor was Neville Mott (much later Nobel laureate Professor Sir Neville Mott), who sorted out all the theory back in the 1930s. It's a shame that no-one at that time thought to try to make a solid-state valve based on that theory. I think it would have been within the technology of the day.

Instead technology went a very long way up what turned out to be a blind alley, using current flows through bipolar junction transistors to represent bits, rather than packets of stationary charge on the gates of field-effect transistors. Although it's not impossible that this too will come to be seen as a blind alley once Moore's law has finally hit the limits. The long-term future may be spintronic (ie, the bits stored as the spin states of electrons).

In defense of FORTRAN

Firstly, one has to specify which FORTRAN. 77? 95? 2008? The language has evolved a great deal, possibly even more so than C++

Secondly, people who attack it fail to realize that even FORTRAN-77 had two huge advantages over its competitors.

One was for the scientist/programmer. The compiler could/can autogenerate code to check array subscripts at runtime. Given the declaration REAL A(100,200) then any reference A(I,J) is invalid if I<1 or I>100 or J<1 or J>200. With the compiler generating subscript checks, many bugs immediately crashed the program, rather than randomly corrupting random data elsewhere. C compilers couldn't do this.

Note also that (say) I=101 and J=1, or I=2000 and J=-1, are detected as programming errors even though in both cases the result of blind address arithmetic will be within A

And when the program was debugged and ready for use in anger, you recompiled with checks off and other optimisations on. Which meant that number-crunching code in FORTRAN could be faster than in C, the second huge advantage.

In particular, a FORTRAN compiler is permitted to assume that in a subroutine

SUBROUTINE FRED( A, B, M, N)

REAL A(M,N), B(M,N)

there is no memory overlap between the arrays A and B, which allows for many optimisations of statements like

DO J=2,N

DO I=2,M

A(I-1,J-1) = A(I-1,J-1) + B(I,J)

...

IN C-style languages A and B are pointers to chunks of memory, and the no-overlap assumption can't be used in nearly so many contexts.

Since F77, FORTRAN has advanced so that now many operations on arrays can (and should) be expressed as a single statement with no sequencing specified by the programmer. The compiler is free to perform whatever sequencing and parallelisation it thinks will work best. Your FORTRAN 2008 code is hardware architecture-independant. Your compiler generates a realisation that best exploits whatever it's running on, be that a pair of Intel Xeons with four cores apiece and a single RAM address space, a top-of-the-range or a cluster of a few such beasts, or tens or hundreds of them, that you wish to use in parallel.

Automatic parallelisation is a big and hot topic and probably still in its infancy. Recent FORTRAN languages have at least freed the compiler from arbitrary constraints accidentally imposed by a programmer who previously had to specify an arbitrary sequence and who couldn't indicate that he really didn't care about the ordering of this or these loops.

That said, I'd stil choose to write the outer parts of my programs in Python (using NumPy, SciPy, and suchlike) and call from there to number-crunching codes written by experts.

Procedural, Object-orientated, and Introspective

There's a lot of obfuscation out there about what is a very simple concept.

Procedural: F(a, b);

Object-orientated: a.F(b)

The advantage of the latter is that you cannot apply an inappropriate F to argument a, because only the methods of the object a are available in this context. It also reduces the number of pointers or object handles one has to keep track of. Of course, it doesn't prevent all bugs. You can still do (say) a.clockwise(b) when you meant a.anticlockwise(b) or a.clockwise(c)

Introspective: in a language like Python you might return to the procedural form, but check at runtime about the exact type of argumernts a and b, and do sensible things if they're not as expected.

Re: Scientific and Engineering Computing

A few people code in Python - and quite a lot of these people use it for intensive tasks, which makes me quite worried for the laptops they then try and run it on

If they know what they are doing, they are using NumPy and SciPy and suchlike. That means that you do the high-level stuff in a high-level language (Python), but delegate the number-crunching (inner loops, BLAS) to library code written in whatever low-level language the library author chose to use. Actually, there are multiple choices: the same library interfaces compiled with different optimisations (say for Athlon, or Intel Xeon, or rewritten using CUDA for offloading onto an NVidia GPGPU).

It's a VERY productive way to go.

The principle was much the same back in the 1970s when a sensible scientist called a NAG library routine whenevr he could. Do as litle coding as possible in (back then) FORTRAN, leave the details of how to get the most out of the hardware and how to tame the numerical methods to the experts. All that's really happened is that a much more powerful and expressive language (Python) has displaced FORTRAN, C and C++ as far as stringing together calls to library code is concerned.

Incidentally the overhead of doing inner loops and all in Python is a factor of ten at worst. In cases where the prospect of getting ten times as much computing done isn't attractive because human thought, not CPU-hours, is the rate-determining factor, then why care about efficiency?

Falling slinky displays slow-motion causality

Re: Both

I think the right way to view it isn't signal theory. It's that there is tension in the spring. When the top is released, it accelerates downwards at a greater acceleration than G, because it is also being pulled down by the tension in the spring.

For every action there is an equal and opposite reaction. At the bottom of the spring, the tension is pulling upwards, oposing gravity. And of course, the Earth itself moves towards the Slinky, by some unimaginably minuscule amount.

Re: Speaking of springs ...

It turns into heat. The atoms in a stretched spring are alightly further apart than they would be in an unstretched spring, and therefore there is slightly more energy in the inter-atomic bonds that are destroyed one by one by the acid.

A better puzzle is this one

You have a battery connected through a timer switch to an electromagnet. This is supported on a disk which is at rest but free to rotate on very good bearings.

The timer clicks, the magnetic field decays, the electromagnet kicks, and the disk starts rotating. Where did the angular momentum come from?

Re: Really?

Troll? OK, probably not.

A 33-bit processor would be very silly. It would mean that it had an Integer operations unit that could do 32-bit integer arithmetic and 33-bit pointer arithmetic. But fetching packed 5-byte fields would slow down the memory system compared to fetching aligned 8-byte fields. So the 33-bit integer operations would need to load and store 64-bit fields and fill the top 31 bits with zeros.

And then next year when the manufacturer wants to make a 16Gb version? All your 33-bit code would have to be recompiled and revalidated for 34-bit operation!

The only reason for 32-bit CPUs was that the cost of four extra RAM bytes per pointer was significant back in the days when we were migrating away from 16-bit CPUs. Today, the cost is not significant and 64 bits is the natural size for a pointer, that will be big enough for a LOOOONG time to come. (Hint: calculate the number of protons in the whole Earth. We won't need 128-bit addressing until we're well on the way to converting the whole solar system into computronium. )

Some people confuse the number of bits operated on by the integer processor with the size of a physical RAM address. That can be any number of bits. Virtual to physical mapping goes from a 64-bit number to an N-bit number. Most of the possible 64-bit virtual addresses cause access violations. That's also good: it makes it more likely that randomly corrupted or miscalculated pointers in a program get noticed and debugged! Cue remisiscences about the uses of 0xDEADBEEF or 0xDEADBABE or more boringly, IEEE Floating-point NaNs with the low-order bits set to the address they are stored in.

Also there's a large, though gradually diminishing, pool of software that isn't yet available to run on anything except the x86 architecture. That may be a lot more significant to business customers than it is to consumers.

plug into the BGA1286 socket - boggle

Someone doesn't know what BGA is.

It stands for Ball Grid Array. The balls in qustion are small solder spheres, by means of which the CPU is permanently melted onto its motherboard as per current Atom designs. In other words, the CPU in a Centeron server is not upgradeable (other than by replacing the entire motherboard). Since almost everything apart from the connectors and the RAM is on the chip, that's probably no great loss.

Nevertheless, a 6 watt chip that plugs into any i3 socket ,which doesn't need active cooling, would be welcomed by myself. (Yes, I do know if you spend £100+ on a box, you can find exotic cases that are in effect hundred-watt heatsinks, containing multiple heat-pipes to remove heat from a full-power desktop CPU)

It's also the nature of open source that if there is a need to attach code to some new action taken by Samba, then someone somwhere will open the hood far enough to create a hook. Also that if there's no good reason to oppose the creation of that hook (security?) then that mod will migrate into the main Samba tree quite soon thereafter.

It's the difference between a product that wants to be used and useful, and a product that wants to force you to buy more secret closed sauce (or snake-oil) at every opportunity.

Linux kernel dumps 386 chip support

Re: C'mon own up

I think the right question is "Who the fuck still wants to own and run the latest Linux kernel on a 386". For which I cannot offer any good answer.

The obvious answer to the question as posed, is anyone who has a large investment in a piece of hardware that's still useful and which would be very expensive to replace, which is controlled by an embedded 386 PC that runs linux. I don't have to look after any lab equipment that runs Linux. I do know of two pieces of lab equipment that still run Windows 3.1, and a couple more locked to Windows NT4. When I can no longer fix the computer, the bill for a modern replacement will be five, maybe six, figures.

Re: Mini-Ethernet

Mini-Ethernet? Hadn't heard of it before, but looking at the pictures it's clear that it would have been very hard to fit in a standard RJ45 connector.

Anyone know if it's a standard (like mini-USB)? If so the cables will become widely available at low-ish prices and interchangeable between manufacturers. Maybe we'll even start seeing mini-Ethernet connectors on tablets, where a full RJ45 would be quite impossible.

Re: 1600x900

A sheet of paper printed at 300dpi is about 2400 pixels across and 3300 deep. If you degrade your printing to 150dpi (1200 x 1650) you most assuredly notice the jaggies on slanting linse and glyphs!

300dpi is old hat. Many of today's laser printers are 1200dpi, although I'm not convinced I can tell the difference between a 1200dpi laser and a 600dpi laser. 600dpi looks crisper than 300dpi although that diffrence is more subjective than objective.

Anyway, this shows there is a limit to the number of pixels that could benefit a laptop user, but we haven't yet got close to it with screens and monitors.

Re: @AC 13:00

Carbon-capture is extremely feasible. The plant you need to accomplish it is called, er, a plant. Every year the atmospheric CO2 concentration cycles by about 15ppm (average concentration is now 380ppm). This is because the mass of deciduous vegetation in the Northern hemisphere is greater than that in the Southern hemisphere. This tells you that if we could prevent all decay of fallen leaves, we would probably remove all CO2 from the atmosphere in less than 20 years! (Not, of course, a good idea to go this far).

So: genetically engineer or breed a common crop plant to grow more root than it needs, and to surround parts of its roots with something that will protect the root from decay for a long time after the plant dies (ie, is harvested). Interestingly, Wheat naturally does this to some extent. Its roots excrete tiny silica nodules, and the root inside the nodule does not decay for millennia. Some varieties of wheat do it much more than others. To start with, grow only those varieties. Selective breeding may well further increase the effect 10, even 100-fold. (Think of how we've shrunk a wolf into a Yorkshire terrier). GM might do a lot better still.

Or we could coppice lots of forest, and instead of burning the biomass for power, process it into a form of cellulose that's highly resistant to microbial attack and dump it into a deep ocean trench (from where nature will subduct it into the Earth's core). Such a form (nanocrystalline cellulose) does exist, and in fact has a lot of promise as a replacement for oil-based plastics.

Take it or break it: the return of the drop test

Drop-ability

Surely that all depends on how likely it is to be dropped?

If it's a piece of test equipment that is used on building sites, the ability to survive being dropped onto hard concrete or into a muddy puddle verges on essential. For a camera to be used by a war reporter, even more so. If it's a 24inch office monitor or printer, it doesn't matter at all. OTOH surviving a cup of coffee being spilled onto it, or surviving a sheet of jammed paper being wrenched out backwards by an 800lb gorilla called "sir", are useful attributes for a printer. I've watched speechless as that sheet of paper come out along with a handful of small broken plastic pieces.

My list of unexpectedly tough kit has Fluke DVMs and IBM ThinkPads near the top, and Sony VAIOs near the bottom. An HP LasetJet 4 is tough and longlasting, but does not survive a flight of concrete stairs at the hands of a "professional" removals company.

And the most memorable "failed" drop test of all was an 80Mb (yes MB) disk drive the size of a washing machine back in the 1980s. The engineer unpacked it, took one look at it, and told us he needed to call the insurers. I asked what was wrong - it looked fine. "Well", he said, squinting, "it's an inch wider at the top than at the bottom". Indeed, it was. "And it rattles when you wobble it. And [grin]... it's got a hole the shape of a fork lift truck prong in the side, right through all the controller boards".

Re: I thought...

You don't need WMD if you've colonised the moon. You just need a mass-driver and a pile of big rocks. The first space war may be fought with (updated) stone-age technology and stone-age military strategy, and will inevitably be won by the moon because it's the really high ground.

Heinlein "The Moon is a Harsh Mistress" set this scenario in 2076. 64 years to go. Still just about possible.

Re: @ Michael Luke

Isn't that HAD lots of oil? There's not a lot left, and the Scots may take those dregs with them when they vote for independance ... and shortly afterwards, get invaded by the USA?

Back in the real world, it's actually the USA that again has lots of oil, thanks to fraccing technology and abundant supplies of oil shale.

Windows Phone 8 must be Microsoft's priority one, two AND three

Alert

Is that question rhetorical?

While wrestling with this afternoon's wireless WOMBAT (above), I also took the opportunity to see whether Windows 8 was usable without touching the screen and without loading a Start-menu replacement.

The conclusion I came to was no. "8" out of the box is completely unusable if all you have is a keyboard and a mouse. And a 24 inch touch screen at the far side of a desk would be an RSI-inducing ergonomic nightmare, even if anyone is stupid enough to make one.

PS For some reason I keep getting Windows * when I thought I'd typed 8. Maybe the Register-approved designation should be "splat", in a geek version of Cockney? splat = asterisk = shift-8 with a nod to Intercal, the only language to make BASIC look cool.

Re: fix Windows 8 by making the Metro interface optional

ALL my headaches?

I spent an hour today trying, and failing, to connect a Windows 8 laptop to our "corporate" secured wireless network. Many of the control panel screens are exactly the same under the hood as Windows 7, but where has "Manage Wireless Networks" gone in "Network and sharing centre" when you need it? Indeed, why have they changed control panel yet again to hide or remove previously existing functionality ... for the second or third time since XP?

The problem might be a typing mistake, or it might be something really tricky, but I can't find out how to get it to display what I'd typed in the previous few screens, let alone what defaults it has assumed. I also can't find out how to delete a wireless configuration so that I can try again from scratch. It won't let me try the same again ... says I already have a network called xxxxxxx and dumps me into a black connect-to-xxxxxxxx *-style panel on the RHS that has no options (like, say, right-click properties), and which I already know will fail to connect, for the Nth time. I'll doubtless be wrestling with this WOMBAT again.

Still hating 8 every time it crosses my desk.

Re: It's simple

You think they relate to the average enterprise environment much better?

If they had half a clue, they'd have replaced Windows XP by something which an average employee would think was still Windows XP. Same UI, all the same apps still working, all the same old protocols still working. Even though there would be a shiny new kernel under the hood, lots of shiny new protocols and maybe even a shiny new desktop UI available for use just as soon or as late as the customer decided that they wanted the new features

Doing it this way would even have made more money for them. we'd have paid for the upgrade licenses, rather than hanging on to XP until the bitter end. I'd have been overjoyed if upgrading to my fictional "Windows XP7" was something that I could do a few desktops at a time, overnight, with the users mostly not even noticing that they'd been upgraded.

But no, Microsoft thinks if it says tear it all up and start again (Vista), and again(7), and again(8), everyone will be overjoyed to do just that. F**k them.
