... Not so good in other places thou . Just worry for your self and we will both be dead of old age by then it's the next Gen's problem to suffer through . :-(

Unfortunately so.

So instead of those in power and pollution being "old and wise", what we see is continuing "old and belligerently selfish" and the younger people are to be damned...

Perhaps we really do need a revolution to force some positive change?...


Here are yet more recent examples of extreme denial:


Exxon: An inconvenient truth

In the hot and humid conditions of downtown Dallas, the #Exxonknew ice sculpture - erected by environmental campaigners to suggest the company had known about the science of climate change but had failed to act - did not last too long...

... Exxon and others, green groups say, will be shown to have misled investors and the public about the true state of climate science and will be fined, condemned and buried...

... This is a very big issue for Exxon Mobil as the shareholders believe current investigations into the alleged undermining of climate science are an assault on their First-Amendment rights.

"The fact that people have different opinions on climate change; they have every right to their opinion, whether we agree with it or not - I will support their right to say so," said Mr Tillerson to a hefty ovation.

It is a little ironic, then, that he did not want to extend that same right to all of the press, as the Guardian newspaper was told it was not welcome at the shareholder meeting.

The more under the cosh Exxon feels, the less likely it is to embrace the ideas of outsiders, however mild. If its shareholders are really to take the steps many want on climate change or indeed anything else, green groups will need to find another means.

They will not be told.



Australia removed from UN world heritage climate report

All references to climate change's impact on World Heritage sites in Australia have been removed from a United Nations report.

A draft of the report contained a chapter on the Great Barrier Reef and references to Kakadu and Tasmania.

But Australia's Department of the Environment requested that Unesco scrub these sections from the final version. A statement from the department said the report could have had an impact on tourism...

... Prof Steffen was sceptical about official explanations that the report risked causing confusion over the status of the reef and could impact tourism.

"There's no substance to either of those arguments," he said.

"There was no mention at all that the Great Barrier Reef might be listed as endangered. There was also a paragraph at the end that discussed steps the Australian government is taking to mitigate risks to the reef."...

... It is not clear why Unesco agreed to the government's request to remove the passages.



Ancient crayfish and worms may die out together

... They warn that such a sweeping coextinction is a genuine threat, particularly as modern-day climate change steepens the warming of Australia that has shaped and shrivelled the creatures' shared habitat over the millennia.

Forestry and other environmental changes add to the risk.

"In Australia, freshwater crayfish are large, diverse and active 'managers', recycling all sorts of organic material and working the sediments," ...

"The temnocephalan worms associated only with these crayfish are also diverse, reflecting a long, shared history and offering a unique window on ancient symbioses. We now risk extinction of many of these partnerships, which will lead to degradation of their previous habitats and leave science [and our world] the poorer."

...REAL radios glow in the dark. :P Gawd the tube equipment is HEAVY. I have a rather old 1.5kW linear that weighs over 100 lbs.

It is those dang transformers for the plate voltage, and those high voltage oil filled capacitors.

Can you imagine a modern switching power supply feeding a linear ...

Yep. We have that far too widely spread...

It's called "ADSL broadband" on centuries old+ telegraph wires. Yep, we still use the same system even now. Supposedly the Marketing people market that as "fast and modern" internet... At least the ADSL is not quite 1.5kW band splatter! Then again, the few mW x 1000's of users do go into too many unintended places far and wide...

Oooer until the telcos do at long last go a little more recent and move up to clean quiet efficient near-maintenance-free fibre optics to the home/premises to deliver something nearer to reasonable internet speeds...

Shame about the old-style monopolies...


Until when?

Building robot McDonald's staff 'cheaper' than hiring workers on minimum wage

But will it make the swill taste any better or increase the nutritional value?

Well then... The USA had better get themselves educated to something better than corn syrup and $15/hour.

McDonald's using robot arms could be the best thing ever for the USA and the world! No "Hallelujah!" needed. No guns needed.

Got a spreadsheet somewhere...


The source problem is that we are not measuring reality, or even a consistent consistently measurable abstraction of anything tangibly real. The "Cobblestone" was a useful but imperfect measure for compute-intensive projects. However, since then, we have other considerations and also even vastly differing measures of compute rates between old x86-FPU, SIMD, GPU, and others...

... Try following some of the ideas of NIST calibration to get real?...

(Note, this is a very old discussion...)


Myself, I favor NIST-style calibration to award for transistor-transitions. That should work well for for both compute intensive and network intensive tasks until we move into quantum computing...

Very good this is getting thought about again but a bit more seriously...

One thought that might be out of date or just simply wrong but just to check just the same...


Is there not some server-side code that takes a (median?) average to 'normalize' all the credit rates?

And would that not be very significantly skewed as soon as a GPU result became that magic median value that was taken to be representative of all?... (As in, the credit for CPU-only users would then be seen to plummet.)


As I'm sure is appreciated, great care is needed when applying "fiddle-factors" to attempt to massage the results for whatever is not being directly measured...

At last openly in the news, the profits and coercion and costs of sliming the population with 'processed' foods:


What yoghurt tells us about the obesity fight

... understanding the challenge facing the nation on obesity, yoghurt is a good place to start. It's one of the most common items in our shopping basket. We spend more on it than we do on crisps and bacon.

In its normal state - natural full-fat - it's pretty good for you. It can boost your immune system, is good for your bones and is great at satisfying hunger.

The problem is that a great deal of the yoghurt we buy is not the natural stuff. Instead we seem to like the processed products, which are made by partly substituting yoghurt and adding a combination of other ingredients such as gelatine, sugar and flavourings. It tends to be cheaper to produce per calorie, but nowhere near as good for you.

[...]

Some 58% of advertising spend is on confectionery and convenience food, compared to only 3% on fruit, vegetables and pasta.

Less healthy foods are a three times cheaper source of calories than healthy foods, while promotions cause us to buy 20% more than we would otherwise.

Campaigners call this the "obesogenic" environment and say it is a major reason why we are not eating the right sort of food.

[...]

... Other steps, including a more substantial restriction on advertising, an end to promotions such as buy-one-get-one-free deals and clearer labelling, are now being targeted...



All only after our health service costs are as crippling as the people being treated have been crippled?...

Who has eaten all the profits on that one?...

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...

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...

... 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',

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.”

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...

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."...
