Re: I hope this means their quality won't drop even further...

It may be too early to say SSDs are more reliable. That they less often die a week after purchase is true, but that just reflects no moving parts. The other side of the coin is that an SSD may be far more likely than a hard disk to go from AOK to brick "just like that" with no warning of any sort. I'll have a better idea 3 years hence, because ....

We're now specifying SSDs for desktop systems where the user stores nothing locally. However, for storing multiple Terabytes, there's no alternative to using an HD (or an array of HDs).

Re: Quality drop

That has NEVER happened to me with a Maxtor or a WD.

Wouldn't have bothered to say "batch problem" yet again if you hadn't mentioned that defunct manufacturer Maxtor. Theirs were the only drives that I am convinced were truly defective by design, not just one batch. I suffered multiple failures on multiple sizes and models of drive purchased over a 2-3 year spread and decided never to buy another of their drives if I had any choice. That their finances collapsed and they were bought up for a pittance shortly afterwards confirmed my opinion of them.

And now I find someone who thinks Maxtor was wonderful. Well I never.

Re: I hope this means their quality won't drop even further...

Funny: I've seen exactly the same comment about Seagate drives. And HGST and Toshiba drives.

What's really going on is bad luck and (especially) bad batch problems. EVERY manufacturer will occasionally and inevitably ship a batch of product containing one of a batch of faulty components. If you buy a batch of drives, or a batch of PCs containing drives from the same batch, then if you get two or more premature failures in the batch, you should assume that the whole lot are likely going the same way. In particular, complain in writing during the warranty period, requesting that all the implicated drives are swapped. The vendor will almost certainly refuse, but should your fears be realized you can later prove that the merchandise was not of saleable quality, and that you pointed this out BEFORE the warranty expiry but were given the brush-off.

Digital radio may replace FM altogether - even though nobody wants it

No. It can't sound better. The codecs used in DAB introduce non-harmonic distortion into an audio signal. For music, this is ghastly. Far worse than hiss and crackle, far worse than mere harmonic distortion.

Coverage and bandwidth. Do you think 4G will ever be available on unclassified roads in deepest Dorset or the Grampians, five miles from the nearest hamlet? (And even if road coverage were to reach 100%, what about farmers and walkers miles off anyroad). Do you think there will be enough bandwidth to support any encoding that doesn't introduce so much non-harmonic distortion as to turn music from a source of joy into a source of pain?

Re: DAB Bashing

Perhaps someone will come up with a converter box that rebroadcasts a single channel on a FM frequency, over an area of a few tens or so square meters.

But it'll sound even more crap than a pure DAB radio. And it'll do nothing to address DAB's other weaknesses. It won't get you a signal that doesn't keep dropping out on the move (es[ecially in rural parts), and it won't give you the battery life of an FM radio if you want to listen somewhere that a mains or automotive electricity supply is not available.

The Raspberry Pi: Is it REALLY the saviour of British computing?

Re: Great expectations...

But why use the PI to do it?

Because - see "androgynous cupboard" below - it's cheap enough that if you break it, you don't need to cry. A new one won't break the bank. That's particularly important if you are interested in tinkering with hardware.

But even if "all" you have done is accidentally nuked the hard disk of a PC while trying to repartition and install Linux alongside Windows, there is lots of work to get it back to how it was and maybe lots of data you will never get back. Lots of expense also, if you didn't appreciate the importance of making some factory restore DVDs on the day you unpacked it (assuming you did get to unpack it yourself). If it wasn't strictly speaking your very own PC, but a shared resource, people will be blaming you. Not a nice place to be, especially not for a kid.

Re: Mind your language

Personally I'd say that teaching any language that needs a compiler as a first language is misguided and verging on cruel. Any scripting language is better simply because there's so much less of a learning curve to climb. No edit-compile-run infrastructure. No debugging of address / overwrite errors. If you're unsure of something, just try it in immediate mode at the command line and see what happens. Python is particularly good because it is also a very well-structured language (c.f. BBC Basic or, gag, Perl).

AFTER a kid has mastered Python is the time to explain that compilers generate code that runs maybe three times faster if you have a problem for which that actually matters, and what you have to give up in order to gain that speed. As computers get faster and open-source Python libraries of other people's numerical codes expand, such problems get rarer.

If a kid can't "get it" even in Python, a career in something other than programming beckons!

Re: About the cost.

You also need a case, a decent display with HDMI input, a power supply, some SD cards, a USB hub, a keyboard, a mouse, a network cable long enough to get to the ADSL modem, and a fair amount of desk space.

Don't need a case (or can improvise with cardboard or grown-out-of Lego). Keyboard and mouse can probably be scrounged for free or liberated from a council tip. Display maybe likewise, or jack it into any half-modern TV. SD card, you can probably scrounge an old small one from anyone who does photography, or source it for pennies on E-bay. Desk? No, floor or lap will do if nothing else available. Next to the router, if needs must and you really can't get hold of a long enough network cable.

The rest of the argument is a little bit stronger. Low-level programming is always going to be a minority interest. But now it's no longer restricted to a minority of a minority - wannabe hardware hackers no longer need parents who can buy a PC and unusual interfaces, and another one, two or more when your kid's attempts at homebrew electronics let the magic smoke out.

If you have a kid with hacker nature, the kid will be like a duck in water and you won't have to explain anything much, just answer the questions and encourage him. If your kid doesn't have hacker nature (probably 19/20 kids), trying to teach, explain to or encourage her will just put her off programming for life.

Hard-as-woodpecker-lips MOUSE GOBBLES live scorpion, LAUGHS off stings to face

Nigel 11

Re: How friggin awesome is evolution!

It can't be evolution - if the poison kills you, then you can't breed in a protection against it, therefore this is 100% proof that evolution does not exist.

I should think that how this evolves is something like this.

To start with, the mice attacked scorpions the same way mongooses attack cobras. Very carefully. They're faster and smarter than their prey, so mostly they get to eat it rather than die. The less nimble ones get dead more often, and the species gets nimbler. Note that all hot-blooded species have a fundamental advantage over cold-blooded ones in the morning, before the cold-blooded ones have a chance to re-warm their bodies from the overnight chill.

Sometimes when battling or eating the prey, a small amount of venom gets into their bloodstream. Enough to harm but be survivable. Genetic variability means that for the higher doses, some survive and some don't. Gradually, genetic tolerance of the venom gets bred in. When a sting ceases to be lethal 100% of the time, risk-taking mice gain an evolutionary advantage over the original extremely risk-averse mice.

And so by slow and gradual evolution, you arrive at mice that laugh at scorpion venom.

I'd guess that the final stage is that mice which feel less pain when stung have a slight advantage over ones which do. Pain is distracting, so they more often get caught by larger predators if they suffer pain? That would create an evolutionary bias in favour of "hard" mice.

One other thing: ability to acquire tolerance of venoms by an individual is near-universal in mammals, including humans. It's the standard immune system response. The immune activity degrades a foreign protein before it can fatally degrade the host's proteins, and is then primed to mount the same response faster and better next time. Immune responses are passed (or primed) from mother to child via breast-milk. It's an area we don't yet fully understand. There may be epigenetic factors at work, and Lamarkian evolution may not be completely discredited when it comes to inherited immune response. Just a thought.

Intel: Our first five parallel-computing schools are open for business

Nigel 11
Silver badge

One way to think parallel

One way to think in parallel is a spreadsheet!

Behind the scenes, a spreadsheet keeps a list (graph) of which cells depend on which other cells. Provided the dependencies are processed in the right order, you can recalculate each cell in parallel with many others. LibreOffice has the use of GPGPUs for calculation as a future goal.

Of course, most actual spreadsheets are not large enough to keep more than a single core significantly busy, but one might "code" for parallel execution using a program design methodology that looks a lot like a spreadsheet and it's underlying, automatically generated, dependency graph.

More generally, the problem is software. At present we do parallel coding mostly using sequential languages and the spawning of multiple execution threads. Other approaches are needed, with the computer doing the parallelisation, not the human programmer.

The irony is that nature worked it out a very long time ago. A brain is a parallel processing system par excellence, 10^11 processors operating asynchronously at something like 20Hz. But it's possible for an evolved system to be beyond the understanding of that system, and so far even insect brains seem to be beyond our ken.

Re: Old school assembly language programmer

Hardly. Old-school assember newbie who didn't know what a macro or a pseudo-op was.

You'd code

SWAP R1,R2

and the macro or assembler would generate the sequence of XORs if that was the most efficient way to do it on your CPU. If the hardware vendor hadn't written it for you, any self-respecting assembler programmer would have written it for himself.

I once saw an enormous macro to implement

SETCONST register, value [,scratch_register]

which avoided loading a constant from RAM for about a thousand commonly and less commonly used constants on an early instance of what would later become known as a RISC architecture.

Black hole boffins close in on gravity waves

Re: Gravitational waves?

An orbital death spiral is exactly what will happen to every orbiting system in the universe, given enough time. "Enough" is a lot (hint: many powers of ten times the current 15-billion-year age of the universe). Gravitational wave emission becomes humanly measureable only where nature throws stellar or greater masses around in really tight orbits at significant fractions of the speed of light.

You aren't upset about the electromagnetic death spiral that will overtake orbiting electrically charged bodies at a rate many orders of magnitude faster, are you?

Re: Impressive work

It always seemed obvious that a GW detector near a big particle accelerator should be picking up feint but repetitive pulses when the accelerator was running.

The key number to bear in mind is the relative stength of the Gravitational force and the Electromagnetic one. Electromagnetism is about 10^42 times stronger. This is one of the most staggering numbers in physics!

In fact, you can deduce this from thinking about the everyday world. You can dangle a few kilogrammes on a fine thread. Attracting in one direction, the entire Earth. Balancing in the other direction, electrostatic forces between the atoms in the thread. Which are themselves mostly self-cancelled within the atoms (electron charge cancelling proton charge): the attraction between atoms is the result of small asymmetries of charge distribution, which is still sufficient to hold molecules and crystals together against the pull of an entire planet.

The same number is the reason you aren't going to observe gravitational waves for anything less than extreme cosmological situations where there's a star or a galaxy's worth of mass moving close to the speed of light.

Re: Limits of doubt

Not detected, therefore limited. Not enough so at this time to cast doubt on GR. Enough so to cast doubt on some models of galaxy formation (in particular, on the formation of multiple large black holes in their cores and subsequent merger dynamics of these hypothesized large black holes).

A thought I had was that the cosmic era of large black hole mergers may be over (i.e black holes in galaxy centres interact strongly enough that they merge into one within, say, a billion years of the galaxy forming. Since all neaby galaxies formed longer ago than that, mergers won't be happening any more, bar rare events such as colliding galaxies.

One might even be able to apply the Anthropic principle to this (would a universe with frequent mergers of large black holes in our cosmological neighbourhood be compatible with mamalian life on a planet's surface? I'm thinking about cosmologically nearby Gamma-ray busts. )

Re: This is why the UK Governments PV subsidy is stupid

It's quite possible to transmit electricity 1500 miles, with modern UHV DC technology. That's the distance from the UK to the Sahara desert.

It's also less bad than that 1500 mile figure suggests, because in practice you'd tend to displace Spanish electricity to France and French electricity to the UK.

The biggest problem is the (in)stability of North African states. Huge solar farms in the Sahara would be a massive capital investment, and we just don't have confidence that the natives wouldn't hold us to ransom or just scrag it. Morocco is probably the best bet, but also probably not good enough. Especially not South of the Atlas mountains.

However, I am surprised there aren't more Spanish olive farmers grubbing up their trees and planting solar panels. Not enough grid capacity? Hello EU, where are you when we need you?

Could we cede the Olive business to the Moroccans or is it too dry there?

Re: @Pirate Dave RE: Always a PC

Where would a company go which had fully committed to Gnome have been when the developers chucked away the Gnome 2 interface because they were bored with it?

This is a good example for FOSS not against it!

Firstly, in the short term there's absolutely no reason to change what you've got on any particular near-future drop-dead date. Those of us running RHEL5, RHEL6 or the Centos or Scientific Linux free derivatives still have a fully maintained Gnome 2 environment, with guaranteed support for five years after RHEL7 ships.

Secondly, within six months of Gnome 3 hitting the decks, the horde of disgruntled Gnome users had fixed the problem in two ways. They forked Gnome 2 into a new project called MATE - the reactionary route. And they developed Cinnamon, a new UI overlay on Gnome 3 that was far less unfriendly to Gnome 2 fans - the progressive route. I'm happy to move to Cinnamon if / when my platform of choice (Scientific Linux) moves to Gnome 3. I've tried MATE and it works. I've stopped grousing about Gnome devs flouting OSS conventions (ie you do NOT forcibly tear up your user's old way of working, you DO fork a new project and find a maintainer for the old one), because it's gone from a huge annoyance to an irrelevance in under a year.

Thirdly, there were and are are other alternatives. KDE. XFCE. Many other other alternatives. Compare Microsoft's one and only one UI, that they tear up at a whim every few years. (Win 7 was a tear-up, Win 8 a shredder).

Finally, you have the source code. If the above hadn't happened because you were a tiny minority, you could still have maintained your chosen interface for ever, or paid someone to do that, provided your pockets were deep enough. You can't do that with Windows XP. Microsoft has the secret sauce and intends to burn it.

If you do receive a surveillance request it becomes illegal to swear that affidavit (i.e. perjury).

Re: I would love to have a UHD or 4K monitor @RandomHandle

But you couldn't resolve your pixels, because it was a cathode-ray shadow-mask colour tube. Say 0.25mm phosphor-dot spacing, 20 inches across a good one, 20 x 25 x 4 / 2 pixels = 1000 pixels. That divide by two is there because one pixel was a triangle of R,G,B dots. Yes, you got some degree of super-resolution on information encoded as luminance (a good match to your retina), so QXGA wasn't completely wasted. You can argue for /1.5 or even /1, but the display was no way as spatially clear as a 1920x1080 TFT. Analogue, not digital.

OTOH colour quality, for reproducing photographs, peaked with the last of the IIyama/ Sony/ Philips 25 inch vacuum-tube monitors and has declined since. On the plus side it no longer takes three people to manhandle a high-end monitor into place, or a meter-deep desk to support it and a keyboard.

And good big tube monitors cost a fortune back then, so a fair comparison is probably one of the newest 2560 or even 4K ones. These days you get 1920x1080 for well under £200.

Solar Thermal storage

The other way to store energy from sunlight is extremely simple, and doesn't even need Solar PV cells. Concentrate the sunlight with a big mirror. Use it to melt stuff. Generate electricity using the molten stuff to generate steam and spin turbines. "Stuff" is one of a number of possible salts and metals (and maybe polymers, if a good polymer chemist sat down to think about the requirement).

For overnight electricity, pump the molten stuff into a big well-insulated tank, for use to generate steam after sunset.

Solar-Thermal doesn't get the press that Solar-PV does, but I'll hazard a guess that polished aluminium mirrors will always be cheaper than high-tech PV panels.

If you want more parties, you need some kind of preferential voting system, so votes for the least popular candidate are distributed according to next preferences amongst the remaining candidates - repeat until one candidate has more than 50% of the vote.

Actually, not true. The simplest and probably best system (except never tried on a large scale) is approval voting. You mark every candidate who you'd be willing to see holding office. You can vote for one, or all-but-one, or anything inbetween. The votes for each candidate are counted. The one with the most votes is elected.

One huge advantage is that several candidates from the same party can run, representing different nuances of one party's platform. There's no such thing as "splitting the vote" under his system. If you want to vote for a party, then just vote for all members of that party.

Personally I'd make one further refinement: a "none of the above" option. If "none of the above" won, all of the candidates would be disqualified from the re-run of the election that would then take place.

Re: the PC power switch!

In the early days of PCs, the power switch sometimes protruded proud of the case. Back then it was a hard mains switch, not a soft switch. I've seen major damage caused by pushing the keyboard back against the idiot-designed case. Later, the power switch (and reset button) were always recessed. Ease-of-use is not always a good thing. Big red switches ought to come with Mollyguards. Needing three fingers for C/A/D was definitely good design not bad. It's pretty much impossible to C/A/D by any kind of mistake.

Re: Calm Down

This isn't so much a walled garden as it is a thin paper ribbon.

For how long? Until the next firmware upgrade? Until someone decides to replace paper by steel and flicks a virtual switch at Samsung HQ?

Until that sticker disappears from the box, and all mention of region-locking is gone from the documentation, refuse to buy it. This is the only way to protect yourself from slav^H^H^H^Hexploitation.

Other rmanufacturers: this is your chance. Guarantee and advertize that your product will work globally, with any SIM, forever. Do it now. Strike while the iron is hot!

Stupid design

It's a stupid design - a spinning-rust drive balanced on its narrow edge with power and USB cables dangling. What could possibly go wrong?

A colleague had one of this design. The wire got snagged, the (active) drive fell over, and the data was all lost. External hard drives should sit in their most stable orientation, i.e. flat. END OF. If you have bought one of these, run it lying flat. Even if it looks silly that way. Vertical is for books and cereal packets.

A cynic would say the poor design is deliberate. Lusers knock their drive over, blame themselves (or their partner or their cat), and buy another one.
