To be fair, they are not subject to an apartheid policy.

Mr Dan Paul

There is one thing that does unite the world and allow us to see past our differences:

Our dislike of USAian attitude to the rest of the world.

Thank you for giving us that. It is the biggest USAian contibution to peace and goodwill between men.

According to wonkapedia it only takes 3kWh/m^3 for desalination.

https://en.wikipedia.org/wiki/Reverse_osmosis#Desalination

At 200litres per person (a generous amount), that's 600Wh per person per day. Bugger all really.

Reverse osmosis of waste water produces even better efficiency.

You can guarantee though that the politicians want to keep this drought alive. Fear keeps the populace in their place.

Petrol cars are dead in the water, says Tesla CTO waving numbers on the back of an envelope

Charles Manning
Silver badge

"In a petrol car, production of the car is 20% of the pollution, driving is 80% of the pollution."

Based on what lifetime and usage? That "20%" is fixed whether you use the car for 50,000 km or 500,000 km. Many of the numbers are based on some usage model like 100,000 km or 100,000 miles.

My 20 year old diesel HiAce has over 400,000 km on the clock. It has had nothing replaced except one clutch (replaced at 90,000 km due to previous owner being a knob-head - it would still be on the first clutch if I had owned it from new) and normal wear and tear items (cam belts, tyres and brake pads). By my reckoning it has used about 33,000 litres of diesel. And I treat it like complete shit.

What is certain though is that replacing a clunker with a shiny new hybrid - or any car for that matter - does not necessarily reduce pollution.

Re: Sponsors

Rubbish

There are far better ways than that to support open source.

There are perhaps 1000 or so really useful open source projects that could do with some sponsorship. Direct injection into those projects would be far more valuable than the very indirect method of sponsoring storage.

What open source projects need it developer time, not a few bucks for storage.

Where's the value?

I can't believe the punters are that stupid that they think they own all the code in github.

Since most of the accesses to github are via git - and very few via web browsers - there's very little exposure for advertising revenue.

Since it is so easy to replicate a git repository, there is no real "stickiness" to git either. In 5 minutes I can move my repo elsewhere.

Yes, a small service business makes sense, but $2bn no!

Obama endorses 3D TLC flash. How else can you do exaflop computing?

But will it rouse the populace?

The reason the moonshot had a lasting spinoff was that it engaged thousands of kids who got hooked on a fantastic dream about the capabilities of technology.

The late 1960s saw model lunar modules hanging from the ceiling in every second kid's bedroom. Tens of thousands of kids walked around on Halloween dressed up in tin foil space suits.

What are the exabyte generation going to hang from their ceilings and do for Halloween costumes?

Until you can engage a population like that, you won't get a long term benefits.

Small number of computer-aided rifles could be hacked in contrived scenario

Charles Manning

Re: spin drift.

"But in order to break the rotational symmetry (and get this `spin drift'), we also need something else"

Yes, that is indeed so.

Think for a moment of the air forces on the sides of the bullet as it flies along. If they are not the same then the side with the higher pressure is more viscous and the side with the lower pressure is less viscous. That means a spinning bullet gets more "traction" against the higher density air and less against the lower density air. This puts a sideways thrust on the bullet.

This is most notable with side winds. If the bullet is spinning clockwise and the wind is from the right, then the air on the right hand side of the bullet is more viscous than on the left. The bullet gains more traction on the air on the right and is thus deflected upwards (as well as obviously being pushed leftwards by the wind).

Similarly for the same rifle, a wind from the left deflects the bullet downwards and right.

Then there are a bunch of other effects some of which are only meaningful on large projectiles (eg. ships' guns).

Bloke cuffed for blowing low-flying camera drone to bits with shotgun

Charles Manning
Silver badge

Re: Let the arms race begin...

It all depends on the shot you're using...

If this guy just picked up his home defence shotgun loaded with slugs or OO buckshot (9 balls) he would be lucky to hit a drone, but the projectiles travel a reasonable range.

If he had lighter bird shot in there, the pellets don't fly as far. 7 or 8 (typically used for skeet) does not make it past about 300m or so but have lost their ability to cause any damage long before then.

The ideal anti-drone shotgun load would probably be some sort of "chain shot" using nylon and rubber balls. Absolutely zero danger to people when they come down, but would cause a lovely tangle on the props.

How to quietly slurp sensitive data wirelessly from an air-gapped PC

Charles Manning
Silver badge

... and sound proof too...

In the 1980s I worked on a computer that had a whistling power supply. The ferrites would squeak at different amplitude/frequency depending on the load. You could run a for(...) loop and count the iterations by listening to the warbling of the power supply.

... and light proof too... since you can get info out via the screen.

... and heat proof too... since you can get info in/out via temperature sensors and CPU load causing increased temperature.

... and operate from a battery... since you could also get data in/out by modulating power draw or monitoring voltage on the power cables.

... and no doubt tens of other mechanisms.

Bandits

"It's better to be ruled by stationary bandits rather than nomadic ones, to be sure, for they will at least farm you rather than just steal everything."

Wrong, the nomadic ones are better.

The stationary bandits do farm you, but they manage to convince the populace that it is for their own good, so people welcome them and accept their lives of tax servitude.

The mobile rape and pillage sort are obviously bandits and the people see them for what they are, so people defend themselves and get rid of them.

Just ONE THOUSAND times BETTER than FLASH! Intel, Micron's amazing claim

Charles Manning
Silver badge

Re: No more loading of apps?

What you're talking about is NVRAM.

The article talks of read time and writing algorithms, so this does not sound like NVRAM. It is still flash-like.

It is also not clear if the devices would support random access (like NOR flash) or page access (like NAND flash). I suspect it will be page access like NAND flash.

NAND flash takes a while to read because the read command has to wait until the read logic settles. This can take a reasonably long time with the long NAND chains. After that there is still the overhead of doing the actual data transfer.

Having been deeply embroiled with flash for the last 20+ years, it is interesting to see some competitors emerging.

Buy a Tesla for the good of Australia, say country's dino-burners

Charles Manning

A wee bit of common sense

Due to all the extra PV, the daytime usage is down, but the night time usage is not. People still want to cook and watch telly while the the sun isn't shining.

So they really want you to increase your daytime use and not your night time use. That flattens out the demand curve too, which allows big generation plants to operate more efficiently.

When are you going to want to charge your car? At night surely, while you're at home.

The only way to get daytime charging up to any significant level is by fitting charging stations in office car parks, malls, etc etc etc. That's a hell of an infrastructure that would make the whole smart meter fiasco look tiny. Lots of gravy for the industry.

Re: Actually, a success for consumers, I think

Nope. Intel has a parallel tack of acquisition and divestment that is almost as bad as Microsoft's

They bought StongARM from DEC, developed that into the fantastic XScale range of processors, then sold it to Marvell.

They developed then dumped a wide range of embedded CPUs.

The same for flash - both NAND and NOR.

The same for USB chipsets.

Now they wonder why the embedded industry is shy about designing anything with Intel in it. As soon as you start shipping, they'll make the parts you depend on obsolete.

New study into lack of women in Tech: It's NOT the men's fault

Charles Manning
Silver badge

Re: How about construction then?

The main point I'm trying to make is that these gender biasses are just natural and we'll break things if we try to force then to obey some idealogical ratio.

Back in the 1960s, medical doctors were almost exclusively male. Until then there had certainly been a socailly driven gender role bias that made medical doctoring a male profession. By the 1980s there was a large % of females in medicine. When I was at university in mid 1980s my gf was a medic. Around a third of her class were female. Now over half the medical graduates are female.

From that you can see the effect of Western women's lib which opposed gender bias in the late 1950s/ early 1960s. There was a lag for the changes to be felt, and the early 1980s was when the change came through.

So why did the same happen in engineering? It would be absurd to say that medicine was given the nod, but the patriarchy held on to engineering as a male domain.

Nope, the restrictions were removed. Engineering etc just has less appeal for women as a group.

How about construction then?

Construction, roadworks, rubbish bin operators, truck drivers. mechanics carpenters... no maths required there, yet not many females in those occupations either.

Let's just face facts. Different jobs appeal to different people and for some reason or other the set of people who are drawn to STEM is typically male.

This is not necessarily a problem and doubtlessly any PC government program to intervene will just end up causing more problems than it solves.

GDP is a severely broken measure

It does not distinguish between production (which strengthens an economy) or consumption (which weakens it).

Nor does it even see subsistence economies like parts of Africa where a large % of people feed themselves, build their own houses, without any money changing hands. and economically live on thin air.

Re: The 1930s

Nothing every happens in a vacuum and it is an over-simplification to blame Hitler's rise on deflation.

The punitive reparations of WW1 made German antagonism inevitable. These were exacerbated by France annexing part of the Rhinelands when Germany could not pay its reparation fines. Of course this would lead to German aggression.

Looting invaded lands to feed Germany was partially justified by this being restitution for the reparations and annexation. Germans felt France in particular had taken more than it should.

As the saying goes: "Cometh the hour, cometh the man.". If Hitler had never been born, someone else would have done the same.

Getting rid of dress codes

Many years ago I worked in a place that tried to have dress codes and the manager was a huge fan. He claimed people wrote better code when they were "professionally" dressed.

Over a week end I wrote the code for two modules at home. One was written wearing a suite and tie. The other, completely naked

I then passed the files around the office for people to compare for "professionalism". It came back 50/50.

Silicon-happy ARM engorges its profits by a third – so its shares dip

Charles Manning
Silver badge

Counting phone sales was probably Ok.

ARM goes into hundreds of different devices from those costing less than 30 cents to those costing hundreds of dollars. For each of those, ARM gets royalties.

Clearly they're not getting much for a Coretex M0 in a 30 cent device. I would be surprised if they get one cent.

They'll be getting a lot more per unit for the top-end devices: mullti-core parts with GPUs etc. Those have historically mainly gone into phones.

Now, however, the top end devices are going into a wider range of devices, so phone numbers alone are not enough.

Beaten blokes HATE the women who frag them in online games

Charles Manning
Silver badge

Re: Eat it, fuck it or kill it

Ignoring, or denying, the fact we're wired this way is not constructive.

I am not trying to denigrate men. I am one. I am not trying to condone acting on this wiring either. We learn to moderate the urges so we can have a civilised society.

One of the few times we really let the lizard brain loose is playing FPS games. We can unleash the killer - even if just in fantasy. Unsurprisingly, the other lizard brain elements emerge too. Boys will eat more during/after FPS, energy dense foods in particular. So any surprises then that fuck part emerges too?

In our lizard brain wiring we classify things into the three distinct piles: threat (kill it), food (eat it), women (be nice to them for breeding). If they're in the threat pile they don't get treated nicely.

Men in the threat pile are still threats, but not as bad because they fit with our understanding of the world. Men are supposed to be virile champions. Even when they are the enemy, we still see them as being great.

What we don't like is our classification system being messed with. These threat-women that confuse our lizard brain classification system get lashed out at. It's the same for blokes wearing dresses.
