Compulsory perv scanners upset everyone

Nigel 11

No risk to the baby from a scanner, but ....

Millimetric waves don't penetrate the womb. It is believed that they don't pose any risk to the mother, either.

Anyone getting into an aeroplane is about to volunteer themselves for a significant extra dosage of cosmic rays compared to someone remaining at ground level. If a well-informed pregnant woman is worried about being scanned, she would not be flying in the first place, because the cosmic radiation "risk" is well-known and measurable. (And small compared to the terrorist risk).

Nigel 11

Looks like I stirred it up a bit

I'm normally strongly against government efforts to acquire information amout us, to scare us and control us. But I really can't see any harm in them finding out what I look like naked in silhouette, even if they do decide to store the image for posterity. Look back at my posts about ID cards, for example (which they say will help stop terrorists, but which are of course utterly useless for that purpose, or almost any other).

As for the rights of the many and of the few - well, to a large extent democracy is a system whereby the majority can decide on laws that are imposed on the minority. Certainly, I agree that there are some rights, such as the right not to be tortured, or the right to life, that are fundamental and should not be up for grabs by politicians and lawmakers. I do not agree that the "right" to not have one's naked silhouette viewed by security staff is one of these fundamental rights.

Airports are a special case because a bomber can do so much harm with so little explosive. Compare the death toll for the Madrid rail bombings. Ten bombs on four rush-hour trains claimed under 200 lives, despite being suitcase-sized rather than underwear-sized. That's a large part of why it's necessary to scan at airports, and why it's at present impractical for other transport. We'll have to take our chances on the tube.

Suicide bombers smuggling bombs in body cavities? Maybe we'll soon have to allow X-ray imaging of travellers as well. How does the X-ray dose necessary to detect a bomb in a body cavity compare to the extra cosmic-ray dose which we all get from being in a plane at 35,000 feeet or above? Flight staff suffer that cosmic-ray dose for several hours every working day, and aren't obviously any more prone to getting cancer than the general public. Compared to which, X-raying the passengers might be acceptable to myself on safety grounds (and again I'd not object on any other).

The flaw in that argument

Number of terrorists deterred: unknown.

A similar argument says that early warning systems and nuclear missile submarines are both pointless, because there hasn't been a nuclear-armed first-strike since they existed.

Nigel 11

Whose human rights?

It's surely a pretty fundamental human right not to be murdered.

If there were an airline that required me to strip naked in front of security staff before boarding, I might actually regard that airline as preferable to the others. A trade-off between a little embarassment, and a greatly reduced chance of there being a suicide bomber on board.

The choice should be between the scanner, and stripping off in front of security staff of the same sex. The human rights of a hundred-plus passengers who don't want to die should override the human rights of one passenger who refuses security measures which the hundred-plus accept.

But on the other side ...

But on the other side of this argument, we have MI5 and MI6 and GCHQ (to name a few agencies that are supposedly on our side), and numerous corresponding entities in other countries that aren't.

They're specialists in turning information into knowledge (or "intelligence"), which might not bother you, if you have nothing to hide. They have truly huge computer resources. They'll have AIs before the rest of us know that such AIs exist. But they're falliable. The first post on this thread, where the Google executive gets labelled as a paedo because someone of the same name uses the same library, is what you have to fear even if you have nothing to hide.

And if instead you get tagged as a potential suicide bomber as a consequence of a data-mining inference error, the first you know about it might be a bullet in your head. Please remember Jean Charles de Menezes before you respond. (Yes I do know that time was not a computer error).

Google wants to "do no evil", but they'd do well to remember what the road to hell is paved with.

Reasons for x64

The point of x64 is that a single process (or application) can utilize more than 2Gbytes of virtual address space. In certain types of application it is possible that >2Gb of VA space can be mapped onto less than 1Gb of physical RAM without the system paging itself into catatonia. So it can occasionally make sense to run x64 on a system with 1Gb RAM, and it almost always makes sense if the system has 4Gb.

Another reason is if you are developing 64-bit applications on a smaller box. They don't ever allocate >2Gb in your development environment, but let them onto the big iron with a heavier load or model, and they will then.

A third reason is if you run VMware player and *ever* want to boot a 64-bit guest O/S. Incidentally, VMware itself takes advantage of certain VM support available only in x64 mode, and allegedly runs faster on x64. (I've not tested this assertion).

4Gb systems are only one step up from the sensible default these days, and are probably set to become standard pretty soon.

Nigel 11

This is why ...

An anecdote. A rich man was once driving his Rolls-Royce through rural france when he hit an enormous pot-hole and horrible noises started coming from the car. At the next village garage, the mechanic diagnosed a failed rear axle and contacted Rolls-Royce. Their response was that they would be flying out a mechanic with the necessary spare parts and the car should be fixed by mid-day next.

When the man returned from his travels, he did not receive an invoice. After some time, being an honest man, he contacted Rolls-Royce about the missing bill. Their reply was short.

"Dear Sir

"We have no record of the rear axle of a Rolls-Royce Silver Shadow ever having failed.

"Yours Sincerely

"

I suspect that Microsoft likewise prefers not to know of any un-fixed security-critical issues in their systems.

Vista was shite

Vista was shite. I won't repeat my reasons for saying that. But to re-deploy your car analogy, a car can be complete shite even if the engine under the bonnet is a good one. That may apply to Vista, if the engine (kernel) of Windows 7 is substantially the same. Microsoft have done a substantial re-design on the bodywork, and they've tuned the engine a lot better. They've now arrived at a package that won't cause every purchaser to tell his friends that it was a big mistake and he should have bought an Apple.

I'd still have preferred it if they'd kept the older model's bodywork, just replaced the engine and incrementally improved the other details. But as with cars, maybe that wasn't possible. As for Vista, I think even Microsoft would now prefer to relegate it to the history books as fast as possible. Even if it's true that Windows 7 is Vista SP2 (in much the same way as XP is NT SP 12 or thereabouts).

Microsoft Office 2007 migration aches foreshadow 2010

Microsoft shooting self in foot again

The number one problem: as with Windows Vista / 7, they've thrown out the user interface which the Office users grew up with, on all versions up to 2007. A menu bar (with incremental "improvements" at various upgrades, but not intrusive enough that one couldn't adjust as one went). It was insane not to offer an Office-2003 User-interface compatibility mode.

It's also significant that very many Word users know nothing about computers and (dare I say it) are not always particularly motivated. They're secretaries or call-centre staff, or all sorts of people who hunt-and-peck at a keyboard who would prefer not to have to.

As others have said, the best "upgrade" may well be OpenOffice, more compatibility with these users at zero cost.

Nvidia boss: Intel suit to 'transform computer industry'

Silicon merger

> a computer would be magical indeed if its GPU was good enough to exclude the need for a CPU.

The future will probably be CPU/GPU integrated on one chip.

The question will be whether it's the CPU core that does the heavy-duty number-crunching, or the GPU core. Further down that road, whether the two merge into each other, with a bunch of processing pipelines that can be dynamically grabbed by whatever needs them. AMD's recent "modular CPU" architecture is rather begging that question.

AMD owns ATI. I can see why Intel might want to hold this trend back, if for whatever reason they can't buy NVidia. (Could NVidia/VIA be what Intel's paranoia is focussed on? )

More likely, nobody who knew that there were patches that needed to be applied, or perhaps nobody who appreciated that the consequences of cutting this particular corner would be certain catastropic failure. If someone had appreciated the need, I'm sure IBM could have supplied a man to do the work (for a price).

They'll be able to catch up on 12 hours downtime over Xmas. Worst case they pay people to work on Xmas day, though I'd guess that one of the other bank holidays will suffice. That bit of the story makes me think that they let go the man who did the capacity monitoring and planning as well, or deliberately cut everything too close to the bone to postpone the inevitable during the run up to the complete failure of RBS as a bank. Fred "the shred", remember?

Idiots hate people who are more intelligent than themselves. Most bosses are idiots. This goes a long way to explain not just this story, but the entire banking crisis of 2008-9.

Especially after organised crime makes off with the contents of the ID, fingerprint and DNA databases, and DNA synthesizers become mainstream criminal technology ... all within the next decade, I expect.

Methinks the organisations named are being particularly difficult, either out of pigheadedness, or because their firmware contains something that they want to hide (Spyware? Customer-monitoring-ware? Closed-source DRM? ) that they've linked into a GPL-derived work.

@Dark Ian - far worse than that

DNA is far worse than you realize. Your DNA may well turn up on the knife sticking out of the victim.

1. Because you handled it in the shop months earlier

2. Because the murderer has decided to muddy the waters by wiping the knife's handle around the rim of a used pint glass purloined from a pub where you were drinking

3. Because in 20 years' time the national DNA database will have "leaked" into the hands of organised crime, and DNA synthesizers will be available to the same criminals

4. Like 3, except you are not a random DNA sample, but someone that they have it in for. A witness, maybe, so no alibi, and of course you would be claiming some other dude did it ....

Fingerprints are even easier to plant, all you need is a fingerprint or copy thereof, plus some amateur photographer, electronics, and DIY kit. Photo to etched circuit board to silicone rubber on the fingertips of some rubber gloves in under an hour.

@Nick Ryan - how much?

It depends now much of the design is just replication of old fully-debugged stuff. If this is a bunch of P3-Celeron cores connected together with logic that's already well-tried on multi-core CPUs, it may be quite easy - little more than a matter of "joining the dots" with an interconnect layer. The more novel logic is needed on the chip, the more expensive it gets to develop.

The thing I'm wondering is why they don't or can't integrate some RAM alongside each core, because bandwidth between cores and RAM will be a bottleneck. Anyone know? Maybe the appropriate silicon process for RAM is incompatible with the process for CPU cores?

California votes in HD TV power pruning law

Nigel 11
Thumb Down

Stupid, stupid, stupid!

Lets see, a telly is on 4 maybe hours/day and in standby 20 hours/day. They're saying it has to use 50 watts less while it's on, saving 200W/h.

Now consider the standby consumption of a telly. And a DVD recorder. And a satellite tuner. And a games console. And a PC. And a Printer. Alarm clock radio. Audio system. Digital radio. Microwave oven. Duplicate systems used even fewer hours/day in bedrooms, guest rooms, etc.

My home power meter shows that standby power consumption is usually over 1 watt and often over 3, per device. Let's say 10W for the telly stack. 10 x 20 hours = 200W/h, again.

This is complete and utter waste. The TV's remote-control does standby for several years on a couple of AAA cells! They should have mandated that no device is allowed to consume more than a milliwatt when in stand-by, and not bothered about what it uses when it's on. Electronically, that would mean disconnecting the PSU completely from from the mains in stand-by, and running micro-power electronics off a rechargeable battery or large capacitor, which would recharge every time "on" was commanded. Easy to do that with an optically-coupled triac.

Once California had forced the manufacturers' hands into producing hardware that can stand-by on microwatts instead of watts, it would not be long befoe that same technology became universal, saving vast amounts more power all over the world. Chaper then to make just the one "greenest" version, rather than continuing to produce a different version to waste more electricity.

We should all be equal under the law

Irving is an obnoxious nutter, but he has the same rights to privacy and freedom of speech as the rest of us.

It's somtimes justifiable to break a law for the greater good, especially if you are willing to publicise having done so and take the legal consequences as a form of protest. Does this apply here? Doesn't look like it. If they'd found a smoking-gun e-mail which made it clear that he doesn't actually believe what he's preaching, that would be different. Having not found any such, they should have quietly gone away.

"First they came for the communists, and I did not speak out—because I was not a communist;

Then they came for the socialists, and I did not speak out—because I was not a socialist;

Then they came for the trade unionists, and I did not speak out—because I was not a trade unionist;

Then they came for the Jews, and I did not speak out—because I was not a Jew;

Then they came for me—and there was no one left to speak out for me."

Today, "they" - western governments - have designs to record all our e-mails and phone calls. If these "hacktivists" are not roundly condemned for their actions regardless of the nature of their target, it plays right into these governments' hands. It'll be your e-mails next, and then other hard fought-for freedoms. And that is the slippery slope to the sort of government that only an Irving could want.

Next generation spammers rise up in Asia, India and Brazil

WTF?

@Rafael 1 - how many percent

It really doesn't matter as long as it's ever so slightly bigger than zero.

If a spammer sends 150 million spams and gets just one idiot who responds with details of a bank account from which he steals £1000, that's a win for him. Especially if the bandwidth consumed by the spam was paid for by someone else, which is the case if it's sent out by compromised PCs on someone else's net. Ditto if he gets 30 orders for blue chalk-and-rat-poison pills at £33 profit on each.

I've read a theory, that this is why most spam is so lame. They don't WANT to snare any moderately intelligent people who might then create significant "heat" for them. They don't want to be sufficiently plausible to a man on the Clapham omnibus, that truly capable geeks with a hero complex set out to lure them into the arms of law enforcement. They want to ensnare only drooling idiots, who won't have a clue what to do next after getting themselves robbed or conned. This is why, for example, spammers hardly ever put their spam through a spelling and grammar check program.

White noise a solution?

It occurs to me that there is a solution for the neighbours trying to sleep, but being disturbed by vocalisations, that would cost a lot less than soundproofing.

Get a white noise source. 50dB of white noise will sound like silence after a few minutes, but will mask other quieter noises. It's sometimes used in open-plan offices to reduce the disturbance caused by conversations at other desks. Another example is the seventy-plus dB of fans in our server room - doesn't sound noisy when you are working in there, until you discover that the only way to have a conversation is to shout.

Those "natural noises" CDs (breaking waves, windswept plains, babbling brooks, etc) work on a similar principle - some people find them more relaxing than white noise. (The brain treats white noise as silence, and complete silence can itself be disturbing, so add the texture of a natural soundscape).

I once lived in a Barratt box. The wall between my bedroom and my next-door neighbours' was made of paper, or so it seemed. It was most embarassing to hear every intimate detail of their failing marriage that happened while I was trying to fall asleep.

These days I live in a Victorian flat with a proper double brick wall between me and nextdoor. It works.

Spain 'goes 50% wind powered' - in the small hours

Nigel 11
Boffin

Add a beefed-up grid, solar and tidal power

The problems get less if you can bring in more power fron further afield. For this we need a higher-capacity Europe, North Africa, and Middle-East spanning electricity grid. Thinking about wind alone, it's unlikely to be calm everywhere simultaneously. Then throw in tidal power (available only on coastlines, with its own different periodicities to the weather) and Solar power (flat calm in Southern Europe usually means peak sun, though it often means fog in the North where Winter sun is in any case scarce).

Pumped storage can also mean compressed air in large salt-dome caverns. Other forms of energy storage include hydrogen (from electrolysed water) and flow batteries. If the energy one is storing is fully renewable, then inefficiency matters only in economic terms.

I can't help thinking Wind power is ultimately a distraction. We ought to be building that grid, and investing in solar power generation in Southern Europe and the Sahara. In the UK, we need to build the biggest version of the Severn barrage - 15% of our electricity requirements from the tide.

They could make installation far quicker and easier AND save some cost on packaging, if they re-engineered this SSD as a PCI card . (The bus connection would be for power supply only. Data via SATA. Alternatively leave the SATA power connector alone and make the bus "connection" mechanical only)

Of course they'd still need to sell the disk-like variant for notebook systems.

I wonder which is the best mid-life kicker for 1Gb RAM XP systems with older (slow-ish) 40Gb and 80Gb HDDs - this drive, or upgrade the RAM to 3Gb? "Reg", it would be nice for all of us if you benchmarked this. The SSD has the advantage of being able to outlive the system you upgrade with it.

What would be really interesting would be if they cranked up the rpm to the maximum that the platters can stand - probably well in excess of 20,000 rpm. That might be pretty useful in the enterprise arena. Solid-state's biggest weakness is random write of small chunks of data, which would be a really fast-spinning hard disk's strong suit.

They could probably also fill such a disk with Hydrogen gas to increase heat dissipation and to reduce drag. It's so tiny, there would be very little of a safety issue - a few cc of Hydrogen can't make a serious explosion even if some ingenious accident let it all out at once and sparked it.

Adaptec CEO on the ropes after dreadful results

Nigel 11

A rock and a hard place?

These days Adaptec makes multi-SATA RAID controllers for small servers and large workstations.

Their problem may well be that Intel started putting 6 x SATA ports on all their southbridges and motherboards, and CPUs got so fast that software RAID ceased to be a significant system overhead, and disks got huge. Instead of buying a separate controller, just connect a few SATA drives to your motherboard. If using Linux, use Linux software RAID. On Windows, use Intel's (fake)RAID driver.

Which leaves an ever-shrinking gap between >6 disks, and entry-level NAS, for Adaptec, 3Ware and others to fight over.

Government to protect children from zombie paedophiles

Not actually silly

If you accept that such vetting is needed at all, it makes sense not to remove the allegedly deceased in a hurry. If you were a convicted pervert wanting to escape from vetting, one way would be to fake your own death. (It almost worked for "canoe man", and did work for quite a lot of Nazi war criminals).

Records for people "reported deceased" are a lot less bothersome from a privacy perspective, than records for the people who are still alive. Data storage is cheap. Keep the "reported deceased" records hanging around until the person's age would be (say) 150, and then auto-remove them on the basis that no-one lives that long.

Russia planning nuclear-powered manned spaceship

Nigel 11
Thumb Up

Provided the thing never comes back to earth ....

I don't see a problem with building a reactor in orbit and then sending it off into space. Enriched Uranium fuel rods aren't desperately radioactive, an accident while they were being transported up into orbit would not be very serious. It's only after the reactor goes critical, that you really don't want any chance of it re-entering Earth's atmosphere.

As was pointed out above, a space reactor needs very little shielding. For a true low-G spacecraft, you can put the reactor a long way from the rest of the space-ship, connected via a lightweight structure rated for milli (or micro?)-G forces only. Neutrons heading out into space are harmless (half-life 15 minutes after which they'll just join the other protons in the solar wind), and inverse squares will do a lot to reduce the neutron flux that you'll have to shield the crew quarters against.

It's just occurred to me that if you put a lump of Uranium (the reactor core) between the crew quarters and the sun, that would be useful shielding against solar storms as well!

@MarkOne - The difference between IE and FF

The difference is not that one is a bug-free program and the other isn't. ALL large programs have bugs.

The difference is that when bugs in Firefox are found, they get fixed quickly. When bugs in IE are reported to Microsoft, Microsoft has been known to sit on them doing nothing, until such time as either a security researcher publicises the bug, or evidence mounts that black hat hackers are actively expoliting it.

Also, Firefox is open-source, so lots of eyeballs have studied the code, meaning the obvious bugs were fixed long ago. Is that true of IE? Who knows, apart from an unknown number of MS employees and others who signed an NDA. Security by obscurity doesn't work.

PC Refresh Equals PC Disposal

Nigel 11
Alert

@marvin - Recover data from wiped disk

It's not at all impossible to recover data froma wiped disk, if you are an espionage agency or are willing to throw six figure sums at the task. However, if you are only worried about someone poking around using a PC and operating system (typical cracker or criminal activities) you are safe enough after you have written the whole disk to zero or random.

The first problem is that there will be some data left un-erased on the (few?) sectors which the disk decided were dodgy and relocated. Someone with knowledge of the firmware or manufacturer-diagnostic commands can doubtless read those blocks.

The second, bigger, problem is that on the physical platters, overwritten blocks have magnetic fringes down the sides that are not fully over-written. It may be possible to retrieve (some) data from these fringes using special firmware and the drive's own read/write heads. It's certainly possible by dismantling the drive in a clean-room and using a much smaller read-only head or probe to explicitly examine the fringes.

DBAN / DoD multi-pass erase patterns are designed to minimize this risk by repeatedly writing, with patterns that maximise the degree of erasure. Nevertheless, alignment of the heads with the magnetic tracks changes with age and temperature, and so erasure cannot be guaranteed.

If the data on the disk is worth five figures or more to anyone, your best bet is physical destruction. I'm told that at a certain defense establisment, the hda first has holes drilled in it, is then pounded by a big man with a sledgehammer, and ends its days in a vat of ferric chloride solution, which will rapidly dissolve any bits left on the broken bits of disk platter.

Corporate-license Windows, so we can't give that away, nor most of the other software that's installed. So nuke them to Linux. Easy-peasy if your O/S wants to be copied.

boot a stand-alone linux disk

overwrite the whole disk with zeros - we don't have any really sensitive data, so this suffices.

# dd if=/dev/zero of=/dev/sda

Google DBAN if you need a more secure erase.

install a free linux system image

# mkdir x

# mount server:/images ./x

# cat x/linux.img.gz | gzip -d -c | dd of=/dev/sda bs=1M

shutdown, reboot, redeploy as an X-terminal, casual browser terminal, or give the system away. (Get a signed acknowlegement, just in case the new owner dumps it and the PC is traced back to us). They'd also be perfectly good thin clients if we had virtualized desktop systems in our datacentre.

If the recipient wants Windows, the linux install at least shows that the hardware is OK, and how he re-installs Windows is not our responsibility. But with a bit of luck he plays with Linux a bit first, and discovers that he really doesn't want Windows at all.

Linux runs quite happily on old-ish PCs with 512Mb RAM (or even just 256Mb) that were struggling with XP SP3 and which are totally useless for Vista or 7.

Er, NO!

> "the latest version of Xorg that now defaults to, for those of you with a dual monitor setup, spanning the desktop between monitors, rather than cloning between them. Quite frankly, that's the way it should have been from the beginning, but as they say, better late than never."

So be it, but if "dual monitor" is a notebook or netbook with a projector plugged in to the VGA port, then this is very definitely a retrograde step! (Perfection would be auto-detecting whether what's on the VGA port is a projector or a monitor, but I don't know if that's even possible).

I just hope that finding one's way back into clone mode is easier than it is with Windows XP.

Dear Sirs

I recently visited your web site for the first time, and I was informed that I could not proceed further unless I used Internet Explorer. Since IE is not available to users of the Linux operating system, and since IE is well known to be the world's least secure, most buggy, and least standards-compliant browser, my first visit to your site will also be my last.

Darwinian economics should provide an appropriate resolution to this issue in due course.

Yours etc.

But is it better than XP?

Well, is it?

And in passing, could *anything* be *worse* than Vista?
