Can't argue with this good comment from someone who has seen far far more than most:


Sir David Attenborough warns against playing 'fast and loose' ...

... Attenborough is a prominent supporter of an Apollo-style research programme to harness energy from the sun and make renewable energy cheaper than fossil fuels.

“If we could put a man on the moon in 10 years you mean to say we can’t solve the problem of getting one 500th part of the energy from the sun? It’s really a tiny technological problem,” he said.

“We’re proposing a route map in which you look at where the congestions are, as it were, and getting international organisations to look and say, ‘I’ll tackle this, you tackle that’, and within 10 years we’ll be able to produce the whole thing and bingo.”...

... The rest is waste heat.

The current F1 power units are at, or very close to 50% efficient.

Wow!

That's a lot better than all too many electricity power stations!...

Which is what started this thread, that electric cars are not green because power stations are not green.

Which is precisely why we need to get away from dirty old inefficient polluting coal, and then similarly move off all the other old fossils to instead go clean and finally totally get away from all the pollution waste...

We have the technology now.

The main hurdle is overcoming the fossils monopoly to move over investment faster to zero pollution...

All just my opinion and personal observation as ever, but the very careful wording for this article just completely stinks for what I see as some very deliberate poisoning of our farming and all of us be damned!



Banned pesticides 'not equally harmful' to bees [...]

... This study examined the three types banned by the EU in 2013. It shows that different types affect the brains of bumblebees in distinct ways.

Two (imidacloprid and thiamethoxam) were shown to be highly toxic to bumblebees when they were exposed to levels of the chemicals found in the countryside.

They affected their brains, impairing their memory and ability to forage for pollen. The toxic effects also included altering the make-up of the colony, changing the ratio of males to females and in some cases reducing the number of queens.

The third (clothiandin) - a close chemical relative that has not been tested before is shown not to be harmful to bees in the low doses given during field trials. The number of queens in the colonies actually increased.

'Long-term consequences'

Dr Chris Connolly, from the University of Dundee, said: "There has been growing concern over the risk to bee populations from neonicotinoid insecticides and their long-term consequences to essential ecosystem services and food security."

He said: "We can clearly see that the banned neonicotinoids are not the same, so they should be considered independently when considering risk and legislation.

"From our findings, we consider that it is premature to place a permanent ban on the use of clothianidine. That said, a moratorium on its use should continue until the knowledge gaps are filled on its wider impact on other species." ...





The official responses/comment in that article are most illumining.

My personal view and interpretation is that:

  • The pesticide producers blithely rubbish the results as somehow not possibly so;

  • The (supposed) National Farmers Union argue to poison the land regardless (in the same way as they promote the slaughter of badgers to scapegoat them for the ongoing bad/cruel/unhealthy farming practices);



And all in the name of that last 1% of greedy profit at all costs to everyone else. How very convenient this was never or never adequately studied by the pesticides manufacturers and sellers?... Or was it??...

How do we put a speedy stop to such madness?


(And why do we suffer such long histories of FUD and disinformation for continuing long term poisoning scandals?...)

Is this where foods have been turned into addictive drugs to make you crave?...



Why is there so much sugar in some savoury foods?

There's growing concern over too much added sugar in soft drinks, but there's also added sugar in many savoury foods. Why?...

... One brand of ketchup - Tesco Finest - contains 38.1g of sugar per 100g. That's higher than the 34g in every 100g of Belgian chocolate sauce from the same Tesco range...

... It might be argued ketchup - as a condiment - is something designed to be used only sparingly but there are many cooking sauces and ready meals that have surprisingly high sugar contents. ...

... Sugar acts as a balance to the bitterness or sourness of other flavours, such as salt or spices, which means the sweetness isn't tasted but still gives the body the effects of a "sugar rush", just as foods such as chocolate do. So some savoury foods are having the same effect on the body as sweet ones, and causing similar cravings, but with a different taste.

"The brain's saying 'Give me more like that'," says Smith. "It's getting lots of sugar without you actually knowing, so is less able than when eating sweets to say 'I've had enough. Stop now.' It's morally dubious that so much sugar is in things that people don't know or recognise from their tasting...



To my personal opinion: Very slimy indeed...


So... Knowingly unhealthy all along?...

Unfortunately, that sort of example is likely badly unhealthy across all "processed foods" manufacturers...

When people don't know chemistry and are setting global policy ...........

And it's highschool chemistry...

https://en.wikipedia.org/wiki/Electromagnetic_absorption_by_water#Atmospheric%20effects
Water vapor is a greenhouse gas in the Earth's atmosphere, responsible for 70% of the known absorption of incoming sunlight, particularly in the infrared region, and about 60% of the atmospheric absorption of thermal radiation by the Earth known as the greenhouse effect.

http://www.greenmedinfo.com/blog/artificial-weather-revealed-post-9-11-flight-groundings
In the three days that followed the 9/11 attacks, when all commercial flights above the continental US were suddenly suspended, a veil was lifted on the profound, though until that point unconfirmed, effects that aviation-associated artificial clouds are having on our planetary environment.
...
First, it is important to point out that the observed post-9/11 elevation in temperature is not one-dimensional. While clouds, including aviation-associated contrails may lower temperature by reflecting solar radiation off the planet in what is known as the "albedo" effect, they may also raise temperature by blanketing trapped heat preventing its nighttime radiative dissipation.

Again, some propose the industrial scale release of water vapor, a GHG accounting for 60% of global warming, by waving their hands because it isn't CO2! This after experimental proof of water's ability to change global temperature.

Don't propose a fix that is worse than the disease!


Good links there thanks.

The easy fix for hydrogen vehicles if their water vapor exhaust might be a problem is simply to fit a condenser on their exhaust!


Easy...

Next?

From incredibly small beginnings to quickly much greater things?...

(For hydrogen -> electric drive.)


Riversimple Rasa review: Is this hydrogen car the future — or just a gimmick?

Rasa does 300 miles on 1.5 kilos of fuel...


OK, so that's a small start but hey! That's likely ideal for most healthy people.

(OK #2, a special super-sized version is needed for the unhealthy USA proportions!)


Getting back to fuel efficiency... A very interesting summary is given in the comments:

We have used a hydrogen fuel path that we think is most realistic, rather than the one that gives the lowest CO2 figure. This is assuming:
- Natural gas, distributed by pipe, 4,000km
- Steam reformation of natural gas
- Compressed gaseous storage
- Distribution by road
- No CCS (carbon capture and storage)

On this basis, at 200 miles/kg, we have carbon emissions of 39g/km. If we used the figures for electrolysis using wind-generated electricity, this comes down to 4g/km; the reason it is not zero is because of the embedded carbon in the construction of the wind turbines.



That looks to be rather plausible and makes the old fossil fuels internal combustion engine look stupidly wasteful...


This is our only one planet to burn...

Posted 19 Apr 2016 by Profile ML1
... If you re-define the what & how of credit then that would be a whole new series of issues to be found & resolved, just to get back to where we are now.


I agree. No need to redefine what a cobblestone is, or change its value etc, just restore the stated intent. I'm more concerned with the intertwined estimate mechanism, which has several classic engineering instabilities.


(In summary, ramble... ramble... no easy fix. Against my engineering perfectionism, I also agree easiest is to stabilize the present system...)



Rambling:

There are a few good puns defining the cobblestone...

Which are a reminder to check whether we are measuring what is intended...


Some notes that would make for a long essay:

  • The cobblestone is a unit of floating-point + integer operations done. Yet, there are other compute aspects that incur a resource cost such as network and storage utilisation;

  • Should other aspects be rewarded such as turn-around time and reliability and availability?

  • There are other projects other than s@h, some of which have minimal computation and for which the cobblestone is a poor measure if only arithmetic operations are counted;

  • There appears to be arbitrary 'other interpreted value' imposed upon the cobblestone unit used by other projects to give a level of 'feel-good' fiddle factor to the cobblestone counts given.

  • And there is cobblestone deflation in CreditNew dependent on what is seen to be the average cobblestone measured machine. What happens to CPU users when that machine is eventually seen to be a vastly more numerical capable GPU?...



Hence, should we set up a sort of exchange market of the 'cobblestone' to balance what 'cobblestone reward' should be given for other values outside of merely counting the arithmetic operations executed?...


My own engineering view is that we should directly measure in cobblestones for all aspects that we feel should be somehow rewarded. However, with our present structure that would be a huge diversion of effort from more immediate science.

Hence, the CreditNew automatically rationalising/levelling between projects is a good enough fix... Even if a fragile fix...


And then further, we have great disparity of capability between CPUs, GPUs, GPGPUs, and new hardware soon to come...

What should we really be 'rewarding'?

The electrical power people consume for the project, regardless of efficiency/effectiveness? Or should we reward for providing results?...


OK... That's my lunchtime ramble. No easy fix.

Is there a student online willing to pick up the idea of making the cobbleston NIST-based?... ;-) Having a reliable measure based on reality would be useful to be able to more easily compare hardware performance... :-)


Happy crunchin',
Martin

We can have 100% power without costing Our Earth:


Power plan maps out route to follow for 100% renewable energy future

... ‘homegrown power plan’ means it would be technically feasible and cheaper for Australia to switch from fossil fuels ...

... spells out dozens of policy ideas the two organisations say would achieve a switch to 100% renewable energy while delivering more equitable access to electricity and a fair transition for workers in the fossil-fuel industry.

The groups will lobby politicians to adopt the measures in the lead-up to the federal election.

“The institute for sustainable future research shows it is 100% doable,”...

... “We know the vast majority of Australians want a transition to 100% renewables as fast as possible. Basically the only the thing standing in our way is the fossil-fuel lobby and their friends in parliament.”




If there is a positive will, there is a way...

Here's hoping for a little less unhealthy sliming of our world and ourselves from the pollution and poisoning from Big Agribusiness:


Europe bans two endocrine-disrupting weedkillers

The European commission has ordered a ground-breaking moratorium on two endocrine-disrupting weedkillers that have been linked to thyroid cancer, infertility, reproductive problems and foetal malformations...

... Amitrole was responsible for the “great cranberry crisis” of 1959 which collapsed the $50m-a-year US cranberry industry, after residues of the weedkiller were found on harvested berries.

Research was already linking the chemical to suppressed thyroid function in rats and the encouragement of tumours. Protests reached such a pitch that ‘Miss Cranberry’ of Modesto, California, hung an effigy of the US health minister, Arthur S Flemming.



So... If we have know of all this since 1959... Why so long before banning such poison?...

Science is broken...


Rather curious timing and a suspicious Marketing connection?...

That is hot on the tail of the WONDERFUL hyper-being of Sarah Palin who supposedly now has world-wide credentials that outshine all of Science:


Climate change denier Sarah Palin: 'Bill Nye is as much a scientist as I am'

Of all the causes Sarah Palin has embraced in her varied career as hockey mom, Alaska governor, Republican vice-presidential nominee, Fox television commentator and Donald Trump supporter, none perhaps may be as bold or – as she still likes to say, “rogue” – as trying to take down a much-beloved children’s television personality: Bill Nye the Science Guy.

But that was where hardcore climate change denial landed Palin...

... The occasion was the premiere for the Climate Hustle, a film that dismisses global warming as an excuse for government takeover and makes the outrageously false claim that rising carbon emissions are beneficial.

But the real mission for Palin and the makers of the movie – in addition to airing various conspiracy theories – was to register the continued existence of a small but still powerful fringe, even as the rest of the world accelerates its efforts to fight climate change.

On a day when the World Bank president and ministers from Canada, France and Morocco urged governments to step up their commitments to fight climate change, there was a strong whiff of desperation to Palin’s efforts...



All just to promote a film and trash our only one planet?

Phew! Get real?!!

Quite a revelation:



Dolmio and Uncle Ben's firm advises limit on [eating food] products

The firm behind Dolmio pasta sauces and Uncle Ben's rice says some products should only be consumed once a week due to high salt, sugar or fat content...

... Mars said its website would be updated over the next few months with a list of "occasional" products to be eaten not more than once a week, and "everyday" ones.

Those products, including Uncle Ben's oriental sauces, are to be reformulated over the next five years to cut salt, sugar or fat.

Nutritionist Laura De La Harpe ... it should not be difficult to reduce the sugar content of products.

"The tomatoes are quite sweet anyway," she said. "I think they need to trial it I suppose, and just bring it right down to a natural level. I think what would concern me would be if they start adding sweeteners, artificial sweeteners to replace the sugar."...






So... Knowingly unhealthy all along?...

Unfortunately, that sort of example is likely badly unhealthy across all "processed foods" manufacturers...

And for something of an unexpected development:


The truth comes out: Microsoft needs Linux

The rumors are true. Microsoft is bringing Ubuntu to Windows. Sort of...

... "The native availability of a full Ubuntu environment on Windows, without virtualization or emulation, is a milestone that defies convention and a gateway to fascinatingly unfamiliar territory. In our journey to bring free software to the widest possible audience, this is not a moment we could have predicted. Nevertheless we are delighted to stand behind Ubuntu for Windows, committed to addressing the needs of Windows developers exploring Linux in this amazing new way..."

... We've already seen the following happen:

Microsoft bringing MsSQL to Linux
Wim Coekaerts, the man who turned Oracle into a Linux powerhouse, moving to Microsoft
Microsoft embracing Linux on its Azure cloud
Microsoft investing in Linux projects

And now, Microsoft brings Bash to Windows. The juggernaut has finally realized where the future lies...and it is not in the desktop platform. The future is the cloud, SaaS, and virtualization. The future is big data, and massive databases.

The future is Linux and Microsoft knows this...




Steady FLOSS patience and continuing excellence...

IT is what we make it...

Good to see that the Malware developers are striving for unfettered cross-platform compatibility! Why can not 'normal' software be so easily run on any OS and on any of your hardware?

Given long enough, everything will balance out to the proportions you've set for your project priorities. If you've not set anything, then each project should take an equal share of the RAC for your system.


However...

If your machine is not on all of the time, the long tasks for Climate Prediction could go into 'high priority' to ensure they complete by their deadline date...
