Beware...

From my recent experience, you now have to pay monthly for your Microsoft software...

No choice about it.

Quite a story of greed! And the consumers die sooner and poorer...

And quite a story of the ways of 'business' and Marketing:


How one of the most obese countries on earth took on the soda giants

Mexicans love their soda...

... But Mexico also loves the soda industry...

... The decline started slowly but accelerated: by December 2014, soda sales were down 12% from December 2013. And the drop was greatest among the poorest Mexicans – by December they were buying 17% less sweetened soda than the year before. (Terrazas was right – the tax does affect the poor disproportionately. But so does diabetes.)...

... “The governments of Colombia, Ecuador, other Latin American countries, South Africa, India – they’re all looking at a soda tax. The world’s attention is on Mexico.”



Closer to home here in the UK for just one positive ripple against the sickly sweet Marketing?

Tax on sugary drinks backed by MPs

A tax on sugary drinks should be introduced as part of a "bold and urgent" set of measures to tackle child obesity in England, MPs say. ...



And the Marketing victims be slimed to an unnatural early death...

Really only a question of "education"?...

... Gravitational waves stretch the very fabric of our universe...

[...]
Will not the laser beams themselves be stretched/compressed as a gravity passes through? And in exactly to the same degree as the surrounding support structure?

Yes as I understand.
Hence should we not expect to see a null result?...


Another Michelson-Moreley null result?

No because the light travels a much further distance than the length of the interferometer, to quote
And because the role of these beam splitters is to transmit and reflect part of the light, so it means that the light which goes through-- which is transmitted through this beam splitter-- goes to the mirror, is reflected. Some of it goes through, but another part is reflected, and so some of the light will go back and forth for quite a while, and similarly on the other side.

Thanks, good answer...

The "the light travels a much further distance than the length of the interferometer" and time-of-flight with the light-speed light and the light-speed passing of a gravitational wave makes for quite a mind bender!


Which comes to a connected question:

Do the LIGO/VIRGO/GEO detectors detect the gravitational influence of our sun and moon over a 24 hour period?... (In a similar way to sensing the change for a gravity wave?...)

OK for a dumb question...


Gravitational waves stretch the very fabric of our universe...

Is the propagation of light really completely independent of space-time?

Will not the laser beams themselves be stretched/compressed as a gravity passes through? And in exactly to the same degree as the surrounding support structure?

Hence should we not expect to see a null result?...


Another Michelson-Moreley null result?

lm-sensors is for the CPU

Mmmm... A lot more than just CPU temp is pulled in and made available...


One display package I run is gkrellm. The 'lm' part of the name refers to displaying the lm-sensors. Other components are pulled in also.

You may find that has a 'plugin' for your GPU.

Also note that lm-sensors needs to find what can be monitored. That is usual run as part of the install. Even so, may be worth running through the arcanery to manually check what is available...


I note GPU temperature and graphics memory usage to guage utilisation...


Happy optimised fast crunchin!

My AMD A10-6700 is decribed as 4 core CPU on the HP datasheet. But the Windows 10 Task Manager describes it as a 2 core 4 logical processors. I've read on theregister.co.uk that someone is suing AMD on the count of cores in the Bulldozer chips.
Tullio

All amazing Marketing in any direction you might look.

So see for yourself:

Intel use one physical CPU core that then runs two 'hyperthread' logical CPUs at about half the clock rate;

AMD use a unit block that has two full clock rate CPUs.

AMD share the FPU circuitry within a block to give an 'Intel style hyperthreaded' FPU, but also with added flexibility.


So how do you count up the cores and relative performance? By CPU or FPU count or from what you can get from the full system?

Should we sue Intel for conning us with only half speed hyperthreading?


And how many remember Intel's unholy push into the ludicrous pipelines design for the Pentium4 "Netburst" so as to claim higher clock speed for bigger Marketing numbers despite poor technical performance?... And thence onto hyperthreading that similarly happen to embiggen the numbers for Marketing...

Such is my observation of what I see as Marketing compromised design to sell bigger numbers to the number chasers...


Meanwhile, back to what gives most bang-per-buck?...

Happy cool crunchin'

(Tulio, good comments thanks and my comments are purely against the purile Marketing conning those left bewildered... Best wishes!)

I just use aticonfig in the terminal. A little ways from the bottom you will see examples of the command lines. I just select and copy the line with the mouse, then hit control+shift+v to paste it into the terminal. The --od-getclocks will show the GPU load. For the CPU temps you can install lm-sensors and then type sensors in the terminal.
sudo apt-get install lm-sensors

There are some pretty GUI apps that display the lm-sensors readings as dials and charts...

I'd start with a motherboard & case that can handle 4 video cards and go from there.

My personal preference is for GTX 750Tis, other cards have higher performance, but no other card can do so much work for so little power- 60W. Next in line would be the GTX 950/960s.
You could go for higher performing GPUs, but keep in mind you will have to pay for the power they use.

I'll agree strongly with that.

Also, go with AMD + Linux to benefit from real CPU cores for instruction bashing to feed the GPUs and additional GPUs with what you save on software costs.

(On the latest AMD, you have an FPU shared between two CPU cores, hence the FPU count is half the core count. However, most of your number crunching should be on the GPUs... Hence much bigger bang per buck than the more heavyweight Intel.)

From the Number Crunching Windows 10 thread...




... Microsoft Admits Windows 10 Auto-Spying Can’t Be Disabled

... bulk data collection of American citizens, as well as an increasing loss of privacy in the face of the new digital Big Brother State – but amazingly, few are really aware of the fact that even the NSA needs working partners in crime to carry out their assault on American freedoms...

... it appears that Microsoft’s new “operating” (policing) system, Windows 10, has given itself permission to watch your every move through its built-in spying feature ... that it would have the outright gall to build a back door into its latest OS and make it a nonnegotiable clause in the customer’s the Terms and Conditions?...




This really is making the purist nonnegotiable stance FOR FREEDOM and to be free from coercion that has long been preached by Richard Stallman look to be the only good way forward.

How much IT freedom and consequent real-world freedom do people know they have lost?!

That depends on what applications you wish to compare for that hardware.

For example for s@h, look at what RAC others get for your card. For games, compare the games benchmarks (anything above 50fps should be more than fast enough).

And if you take a look at some of the primegrid RACs, that is likely as close as you can get to theoretical 100% performance utilisation.


Let us know what you find!

Under tasks it says device peak gflops for devices 250x and 270x are both the same at 211.73. Makes no sense at all?

I'm sure others (such as Jason or Ageless or others) can comment better than me for Boinc... ;-)

If you have two GPU cards in the same host, then Boinc reports only the Boinc number for the first card found. All your other GPUs are assumed to be the same.

For a mixed bunch, could give cause for some confused scheduling numbers!

Quite a story of greed! And the consumers die sooner and poorer...

And quite a story of the ways of 'business' and Marketing:


How one of the most obese countries on earth took on the soda giants

Mexicans love their soda...

In fact, Mexicans drink more soda than nearly anyone else in the world; their top three daily sources of calories in 2012 were all high-calorie drinks. Mexico also has by far the world’s highest death rate from chronic diseases caused by consumption of sugary drinks – nearly triple that of the runner-up, South Africa. In other words, excessive consumption of soda kills twice as many Mexicans as trade in the other kind of coke that Mexico is famous for.

But Mexico also loves the soda industry...

Reduce soda consumption, Rivera replied. ... to illustrate the ideal balance for daily beverage intake. The idea was to put a poster with the jug in every health centre. “It never happened,” said Rivera. “Opposition from the industry was tremendous.”...

... shown again and again that diet is a far more important factor in obesity than exercise. And over the last two decades, the Mexican diet has been transformed. Consumption of beans dropped by half. In the last 14 years, consumption of fruit and vegetables dropped by 30% – largely replaced by processed food and sugar-sweetened beverages...

... little stores sell packaged biscuits, pastries, doughnuts and cakes, and sodas and non-carbonated sweetened drinks. When you’re hungry, you can buy a Gansito snack cake and a soda for about a dollar. It’s fast and cheap and delicious.

The evidence is overwhelming that excess sugar consumption is the largest factor in the global obesity epidemic. Excess sugar is also by far the most important driver of diabetes, even among thin people...

What keeps soda executives up at night is the spectre of a soda tax. They don’t worry about lost revenue or sales from a tax – it’s the demonisation of their product. Soda is on the verge of becoming the liquid cigarette. So the industry seeks to break the link between soda and disease, and backs research to support that view. Its companies cultivate a health-conscious image – a tactic that, conveniently, also sells beverages. Coca-Cola’s promotion of thousands of sporting events in Mexico is also a key marketing and advertising strategy. And if they can’t actually win friends, companies spend like crazy to buy them. There was a time when Philip Morris and British American Tobacco did all these things, too...

... The decline started slowly but accelerated: by December 2014, soda sales were down 12% from December 2013. And the drop was greatest among the poorest Mexicans – by December they were buying 17% less sweetened soda than the year before. (Terrazas was right – the tax does affect the poor disproportionately. But so does diabetes.)...

Cheeky or ominous?

This is The Register's take on that:

Next year's Windows 10 auto-upgrade is MSFT's worst idea since Vista

... Right from the get-go Microsoft has made it clear that it is looking for a very fast rollout of Windows 10. The new operating system was offered as a free upgrade for some users – a first for Microsoft – and ever since the launch, Microsoft has been hustling people to upgrade, by fair means or foul.

Earlier this month El Reg's tips inbox hit overload...



The comments to that article make for interesting reading also...



All too unbelievable?

Or is it that most people know no better?

New blog post about how updating to Windows 10 is going to become easier:

Our aspiration is for customers to choose Windows, and to love Windows. ...

Wow!...

Disengage brain. Simply follow the Microsoft approved way...?

There is nothing better?...


I'm sure there have been some books written about that...

How do we better educate those lost in their hasty rushed busy bewildering Marketing/Media steered world instead that unfettered freedom is easily available?

In 2015, your Windows PC can be owned by opening a spreadsheet

Patch your Microsoft and Adobe software today – like, right now...

... Don't forget to check to see if your Microsoft Windows patches include KB3035583, KB3083710 and possibly others, which will try to get you to install Windows 10 by stealth.

THIS is why I tend to get irked whenever Martin (and others) post a veritable joygasm every time someone builds a wind turbine, solar panel, or an electric car. They are IGNORING HALF of the PROBLEM.
And that turbine, solar panel ... is transported to the user with a diesel engine that has cheat software installed making the entire process dump more GHG than the amount saved.

Green, it is a big oil owned scam.

Which is where I have such a big beef against the pollution corruption of Big Agribusiness and their unattainable vandalism of our entire world...

Wherein lies the problem of extreme Kapitalism and the so called business with no morals and supposedly no real world responsibility...

... in the end you will want Windows 10...

In all the great flurry of words and multi-GigaBytes of downloads, one question seems to have been overlooked...


What for those people who are happy with what they already have and simply do not want Windows 10?

They have a choice?...



For those that care to look a little further, thankfully there still is a choice to move away from the ways of Microsoft.

(Very glad I have forsaken the Microsoft mantra from a few years ago. To me, the present game looks to be descending into hell for anyone who values anythign of any freedom!)

Smoking, to me, is Worse than murder and rape.


Aren't you just exaggerating a tad?

Short term, then I'd agree that to be a bit of an exaggeration.

Longer term for those enticing others to smoke or otherwise inflicting their smoking on others... Perhaps that is no exaggeration.


We've got the present furor over the VW cars pollution cover-up. How have the tobacco industry succeeded for so long to cripple and kill their customers with their products without any similar furor?...

... OUR PCs.

I need to put more time into getting a few Window$ programs to run in Wine on Linux Mint. I need to get our network up to speed first, that will happen at the end of the month-ish. :)

...

Keep on BOINCing...! :)

That reminds me of my convert-over period...

I had 6 years of dev projects on win 3.11 wfwg, far too many hours with MS C++ and a lot of careful interprocess working and then... WinXP still didn't have certain critical needed features that we'd been teased along to wait for...

Meanwhile, the graphical desktops for Linux had developed along nicely and... ALL our code recompiled on Linux with nothing more than adding some shim code to de-Microsoft some of the interfaces. The real beauty for some of my work was that the great care needed to make multiple tasks behave nicely was no longer needed. All the tasks ran and communicated very nicely with no extra special tweaking needed. For the sake of productivity, I was kicking myself for not converting sooner...


Which comes too...

Wine was very good and also very subversive...

That environment teased me to linger on with some Windows ways for way past their sell-by date...

Far easier, but much more of a jolt, is to take a day or a week to fully convert to whichever choice of new apps/ways.

I lingered on Wine for about 6 months until hitting a second "Why didn't I change sooner" moment!


(Then again, that was at the time that Wine ran s@h + setiqueue & setimon faster than Windows!)

All just my own humble personal observation/opinion...

... As I said, I've worked in IT for quite a few years now, I've ran into many people with similar mindsets who, yes, clearly don't understand the inner workings of the systems. You can't make all of them understand, but you can remain positive and confident in your own knowledge.

Ozzfan,

Good comments and good patient help. Likely put better than myself.

And a good reminder for some 'highly impatient' types I'm trying to help at the moment whereby:

For some people, it is all too easy to blame whatever they do not understand...


So, really, all IT jobs are only (the mythical) "5 minutes" as assumed by certain people? ;-)
