Having a gun will protect you.

If you are in an environment where you 'need to have a gun'...


THEN EXPECT TO GET SHOT.


It's that simple.

Simply remove the guns for something better.


Geee-whizz... Is that why I turned down a job in the great US-of-A?...

That and the homophobia, xenophobia, and silly long work hours expected regardless of results and regardless of merit. I actually got the comment from a boss saying "Geee, you're too happy, we're not working you hard enough!"... Not that actually, good working made things work well...


Only in the USA...

Good luck!

When do we turn around the lingering old fossils pollution and the corrupt big agribusiness?... How soon?...

ML1, the answer is quite simple, when cleaner alternatives are cheaper in the short term. After all most of the specie seems to have only a short term perspective.
One way to do it with a tax, highly unlikely due to political reasons. The other is better more cost effective green technology.

No tech solves this except birth control. The sooner it is admitted, the sooner the solution is upon us.

While I agree, it isn't quite so simple, the western financial model is built on there being an increase in population so that health and pensions can be financed to increasingly long lived population.

Probably a Catch22 situation as it is education and better health care that led to the increase of lifespan.

And that leads to another political problem, with better education and health care this population sees no need to have high birth rate, so increases in population are met with immigration.

... And better education leads to a lower birthrate as is shown the world over.

Unfortunately, for any political or financial 'crisis': Science, education and the environment are the first to get trashed.

A poorer education and poorer environment are also strong factors that promote a higher birthrate... (To offset the game of (expected) mortality...)


Rather a bad and unholy game...


Can we promote better education and a better environment FOR ALL?

(That also means getting rid of the corruption and pollution...)

Yet more global warming effects that are plain to see across an ever wider view... Just look up in the evening sky with your own unaided eye:


Climate Change at the Edge of Space

... we call them, “noctilucent clouds” (NLCs). They appear with regularity in summer months, shining against the starry sky at the edge of twilight. Back in the 19th century you had to go to Arctic latitudes to see them. In recent years, however, they have been sighted from backyards as far south as Colorado and Kansas...

... These results are consistent with a simple model linking PMCs to two greenhouse gases. First, carbon dioxide promotes PMCs by making the mesosphere colder. (While increasing carbon dioxide warms the surface of the Earth, those same molecules refrigerate the upper atmosphere – a yin-yang relationship long known to climate scientists.) Second, methane promotes PMCs by adding moisture to the mesosphere, because rising methane oxidizes into water...

... Summer is the season for PMCs and noctilucent clouds. As June turns into July, observers in Europe are already reporting some displays, and they should appear over the northern USA within weeks.

Observing tips: Look west 30 to 60 minutes after sunset when the sun has dipped ~10 degrees below the horizon. If you see blue-white tendrils spreading across the sky, you may have spotted a sign of climate change. It happens, even at the edge of space.




When do we turn around the lingering old fossils pollution and the corrupt big agribusiness?... How soon?...

Here is the latest push from Microsoft:


Microsoft's Windows 10 nagware goes FULL SCREEN in final push

Meet the new BSoD – the Blue Screen of Despair

As the Windows 10 free upgrade period draws to a close, Microsoft is stepping up its operating system's nagware to full-screen takeovers.

The Redmond software giant confirmed today it will start showing dark blue screens urging people to install the latest version of Windows. The full-screen ads will pop up...

Hey, it's good to experiment!

I tried a physical KVM switch a few years ago. One plus point is that it keeps things conceptually direct and 'easy'. Minus points are the mass of cables needed and that you can still get yourself confused as to which machine you have (inadvertently) selected!

Since then, and since all my machines are on a Gbit network, I stay settled and comfortable on just the one physical machine and use the various remote connections available on Linux to work with all the other machines (including for my normal work where the machines can be hundreds of miles away).

I try to set things up as commonly as I can (with 2 Debian stable64, 1 Debian stable32 and 1 Gentoo64), and all the users in question are in all the right groups. The Debian32 is going to get updated to Debian64, and the Gentoo is going back to Debian


Very good idea to settle on what you like until you wish to explore further.

I learnt through the DEMO-Linux, Mandrake, Mandriva, Magia route for the 'desktop' Linux distros. Various others were used on odd occasions also.

Alongside that selection, I've moved almost entirely over to customised Gentoo systems, often with no desktop at all!... Works very well but that is quite a lot of new things to learn to move from the other very well packaged 'desktop' Linux distros.

For getting GPUs to work for Boinc:

  • Use the version of boinc that is packaged with the Linux distro;
  • Check the system power settings to set what happens when there is no human activity!
  • Check whichever forums for your distro and the questions forums here for any comments about running boinc.



In the Windows world, some users have to make a dummy video plug to fool the graphics card electronics (or the Windows drivers?) into believing a physical monitor is connected. Is that still the case or has that problem 'gone away'?

Myself, not seen that problem for any of the GPU crunching done here across a mix of VGA, DVI and HDMI graphics cards.

Note: Boinc can get disconnected from the GPU if you are running Boinc as a yourself as a user and you then log off or allow the system to go into sleep or whatever powersaving mode.


Go with 4.6 kernel systems for perf and the various other kernel tools... A lot has happened since the previous versions!

And see:

All the performance monitoring tools in Linux and their functionalities in a single pic


Hope that gives a few clues,

Happy cool crunchin'

'Sleeper issue' of leaking coal seam gas fields may blow hole in emissions goals
Gas has long been touted as cleaner than coal and marketed as a "transition" fuel until the mass take-up of renewable energy becomes viable.

But a growing chorus of voices from Australia and overseas is warning that any perceived benefits could easily be lost with just small leakages.

Professor Peter Rayner from the University of Melbourne says it takes just 1-2 per cent of gas leakage for any advantage to be lost.

That is an even greater problem for the inevitable fracking leaks and abandonment. Especially so when companies conveniently go bust and leave their workings to leak.

We also have outgassing from landfill rubbish dump sites.


There are almost all of our activities that we need to clean up. All must be accounted for. However, fossil fuel use and agricultural land (mis)use are the two biggest and easiest impacts to take immediate positive action to correct.

Not sure if this is a first for the UK but at the moment, we have zero coal fired power station output. That is, all our coal fired power stations are offline.

Instead, as I'm posting now, we have about 17% wind power and about 20% solar (over 1/3rd power generation). Combined cycle gas turbines and nuclear contribute the rest. (There's also about 5% from bio, hydro, and imported nuclear.)


Now we 'just' need to expand on that and increase the capacity of our pump-storage hydroelectric schemes.

Another interesting snippet is that battery storage is being used in some places on the grid to boost peak supply capacity instead of laying new power lines.


Is the great inertia of the Titanic of old ways and old dirty money slowly turning?...

???!...

You are running Linux so...


Yes, you can use a physical keyboard-video-mouse switch.

Or...

Look up using "ssh -X", or look up for using the boinc client to access boinc on other hosts on your network.


Aside: Note that boinc will need to be in a video group to be able to access any GPU resource. A distro install will set that for you. Whereas the Berkeley installer will leave you to set that manually. Do not run boinc as root! There is no need to.

Just slash and burn more rain forest to make farmland to produce the food to replace meat.


Nope. You've got that one the wrong way round.

Reducing the inefficiency of farming the (top of the farming food chain) cattle will allow LESS farmland to be needed than at present.

Wrong. Meat can be fed by land that has too high a slope for a tractor to operate upon. Slash and Burn, it comes to the make it so hand wavers.

Nope.

We don't see cattle on the hills and highlands over here. They usually get the best most fertile flat fields nearest the farm buildings. Or they are incarcerated inside the buildings and fed antibiotics so that yet more animals can be intensively crammed in.


What you do often see over here on the hills and highlands are sheep. Or various contrived crops with lots of drainage for grouse and pheasant shooting. Both of which are a cause of flash floods downstream...

What number crunching are you wanting to do?...

If this is all for s@h, then you will be limited by your GPU capability. Look up the Lunatics optimised apps for the latest developments.

If this is for your own code, then you should already have a good idea about what data flows and what computation flows you need...


So... What are you wanting to try and with what?

(In the Linux world, you could try looking up the details for the kernel performance tooling called "perf" to see real-time real world kernel activity...)


Hope that helps with a few thoughts.

We'll never see our lot do anything like this :-(

Democrats hold "sit-in" protest

I don't get it.

Our Congress has lost the plot.

What is so hard about have proper vetting and due process gun laws?

You are vetted to get on the list and you have due process to get off the list.

If they would just add vetting and due process it would pass in a flash.

They don't want it to pass. They want it to fail so they can use it as political points in the next election. The people who are killed are dead because of party politics. The despicable ones are the party strategists.

They all have completely lost the plot if they are lost for words and have no powers of reason and instead have to resort to non-verbal childish schoolyard tantrums.


That is not what politics should be about. A disgrace to you all!

Only in the USA.

Trucks use waste heat

Engineering360 News Desk video, clip starts at ~2:10
Using waste heat from exhaust to generate electricity.

Thanks for getting us back on-topic.

There is lots of scope yet for getting more efficiency out of the old combustion engine yet. Note: Exhaust heat recovery system


Hence why electric transport is so attractive (much higher efficiency). Provided that is the electricity generation is clean...

Very silly and local people continue to die.


Many many years have passed since the American civil war. Really, is there any need for old out of date needs for a militia?

Reword that today as 'vigilanties'...? And worse as we continue to witness?...



So... Why has Obama been out-voted to save America from their own guns?

Denial unto death to us ALL?...


America’s Largest Coal Company Has Been Bankrolling Climate Denial

... In a revelation that shouldn’t surprise anybody, Peabody Energy, the United States’ largest coal company, has been bankrolling think tanks, corporate lobbyists, trade associations, and individual scientists at the heart of the climate denial movement...

... few have manipulated the facts of global warming as consistently and egregiously as Peabody, which refers to carbon dioxide in glowing terms and asserts that by cranking up its concentration in our atmosphere, the company is fertilizing the planet for the benefit of mankind. Or, as a Peabody lobbyist once put it, doing “the Lord’s work.”...

... the transition off coal is going to have to continue, if we’re to have any hope of preventing the worst consequences of climate change from unfolding. It would be heartening to see a fossil fuel enterprise acknowledge this reality and take a leading role in developing the energy sources of the future. Sadly, like the compressed dinosaur remains they’ve made their fortunes from, most of these companies seem more interested in burying their heads in the sand and staying there.

It has been proven in the past that hosting a smaller number of GPUs on multiple computers will give better results due to better CPU support of those GPUs.



You and I both know this to have been absolutely true. ...


To jump in, I agree also.


In the past when I've looked to support multiple GPUs for running some intensive compute jobs, I've found the best price-performance was always to run a standard motherboard with a mid-range CPU and at most two GPU cards.

All other options of using super-duper top-of-the-range specials for the CPU, GPU or motherboard, or of going to multiple CPU sockets or of using external GPU card enclosures: They all unacceptably jumped up the cost or compromised performance, or both!


The only time you might want the extra expense or reduced overall performance is if you have some task that does not fit well on the size of your individual separate systems.

Boinc by design fits well on present consumer-grade PCs/GPUs. Hence keep with that sweet-spot for Boinc.


There was a "Skulltrail" consumer level two CPU sockets system that did burst upon the scene a few years ago that was aimed at hard-core gamers (hence the Marketing name?). Looking at that, it looked to be far too expensive all for little gain.

Here's hoping the next big jump will be with the newer more general GPGPUs becoming more open for parallel number crunching...


Happy fast crunchin'.

I'm not posting here anymore, since I don't have any real friends here, goodbye.

Hang in there.

This is quite a story for putting so many machines together. A lack of comment doesn't mean a lack of interest.

Note the views count? (36000+ ...!)


Just a thought:

For all the combined wisdom we have on this forum, is there a "s@h crunching" guide anywhere?
