AMD FirePro W9100 16GB Workstation GPU Put To the Test

arielCo In before "$3,300 WTF?!" (42 comments)

From TFA:

Understanding the Workstation Market:

The first thing we need to talk about is the difference between workstation and consumer GPUs. The GPUs themselves are essentially identical -- NVIDIA's Quadro K6000 is based on GK104 (Kepler) the older Quadro 6000 is a GF100 (Fermi)-based chip, the W9000 uses the same GCN core that powers the HD 7970/R9 280X, and today's W9100 is essentially identical to the Hawaii XT core inside the R9 290X. What sets these workstation cards aside are the amount of RAM they carry (typically 2-3x as much as a consumer card), their validation cycles (workstation GPU cores are hammered on far more than the consumer equivalents) and the amount of backend vendor support and optimization that AMD and NVIDIA both perform.

This optimization process and long-term vendor partnership is what distinguishes the workstation market from the consumer space and the need to pay for some of those development costs is part of why workstation cards tend to cost so much more than their consumer equivalents.

Two were direct replies and the top-level post got me a nice reply from the developer's brother. Screw karma, I've got enough for whatever it's worth.

Nice! Can you lead us to a more technical article? Even the bit from Oxford is light on details.

Rocket Scientist Designs "Flare" Pot That Cooks Food 40% Faster

arielCo Coanda effect? (204 comments)

It looks like there's more to it than increased surface area - the Coand effect may be at work here, making the plumes of hot gas creep along the "trenches" rather than flare out. There's a video where it kind of shows what I mean at (1'25").

Then again, this may be just a case of increased area for heat transfer. I'm not a rocket engineer.

arielCo Re:Long time to boil? (204 comments)

Ok, how about: "it boils colder, making cooking slower"? Because that's what mountaineers and other people at high altitude complain; e.g., pasta takes forever to cook properly (whatever they mean by it), resulting in a goopy consistency.

Oklahoma's Earthquakes Linked To Fracking

arielCo Re: A good thing (154 comments)

Yes, another /.-er said that weakening of the gas-rich strata changes the stress field, causing reacommodation in places that were previously stable. Is there any serious before/after record of displacements / etc (besides seismic events) to build a solid case in court / regulators ?

Oklahoma's Earthquakes Linked To Fracking

arielCo Re: A good thing (154 comments)

I learned after posting that comment that some of the quakes happened in places without a significant seismic history. And thar the fracking may have caused a redistribution of stresses by weakening the gas bearing strata. (Which is not the same as crowing "You said you weren't causing quakes and now you can! Which is it, huh? Huh?")

The fun part will be taking Big Oil to court. How well have the areas where they operate been monitored?

Oklahoma's Earthquakes Linked To Fracking

arielCo Re: A good thing (154 comments)

I thought all quakes dissipated energy reducing the total stress, but this may still be true while increasing concentration elsewhere as you suggest. Another reply to my comment says that the fractured layer isn't as strong as before, resulting in new shifts and accomodation in faults that were stable. What do you think?

Oklahoma's Earthquakes Linked To Fracking

arielCo Re: Not a good thing (154 comments)

Yes, the "small force triggering a big release" part is alright. The flaw lies in assuming theres a single bowling ball; to follow your analogy, imagine that balls keep coming in at a more or less constant rate until the shelf flexes and all come down (avalanches work like this too). Wouldn't you rather shake the shelf to make one ball fall at a time? (IIRC, avalanches are sometimes triggered on purpose).

Plate movement doesn't stop either, and the fault can accommodate and dissipate its stress in big or small jolts. But again, read the other post I told you about.

Oklahoma's Earthquakes Linked To Fracking

arielCo Re:A good thing (154 comments)

So it's not really about faults accommodating plate displacement, but about new dynamics created by collapse in the fractured rock. And the statistics suggest that something is indeed changing. Are there any measurements of the strata backing up this?

Oklahoma's Earthquakes Linked To Fracking

arielCo Re: A good thing (154 comments)

Yes, there's a reply to my original post that the fillers do not stabilize the damage well enough, and that's causing new dynamics in faults that were until now quiescent.

Oklahoma's Earthquakes Linked To Fracking

arielCo Re:Not a good thing (154 comments)

That analogy doesn't resemble fault dynamics at all. Perhaps a better one would be pushing a heavy object along a hard floor; as it moves, some points of contact stick, flexing the structure a tiny bit until the stress exceeds the static friction, and every little jolt is like a seismic event. That's how regular fault accommodation causes quakes, and the longer the points of friction are stuck a bigger jolt becomes more likely.

But never mind - there are other replies to my top-level comment that propose other sources of stress / energy.

Now we're talking. There's one thing that doesn't add up to me: does the energy delivered by the process approximate the energy released seismically?

Pussy Riot members jailed for two years for hooliganism

arielCo arielCo writes  |  about 2 years ago

arielCo (995647) writes "Three members of Russian punk band Pussy Riot have been jailed for two years after staging an anti-Vladimir Putin protest in a Moscow cathedral. Judge Marina Syrova convicted the women of hooliganism motivated by religious hatred, saying they had "crudely undermined social order".

On 21 February, as a part of a protest movement against the re-election of Vladimir Putin, four women from the group came to the Cathedral of Christ the Saviour in Moscow, crossed themselves, bowed to the altar and began to perform a song asking the Virgin Mary to "drive Putin away" and describing the openly pro-Putin Russian Patriarch, Kirill I of Moscow, as someone who believes in Putin rather than in God, but after less than one minute guards cut short the performance and escorted them outside."

Iran Discovers "World's Largest" Helium Reserve

The volume of the world's helium reserves is 40 billion cubic meters and the South Pars gas field [reportedly] holds 10 billion cubic meters of the total amount."

Venezuelan Govt seeks Internet content bill, NAP

arielCo arielCo writes  |  more than 3 years ago

Ah, none is more coward! (995647) writes "Several local and international news outlets report that the overwhelmingly pro-Chávez Venezuelan National Assembly is considering to reform their Social Responsibility law to include Internet content. Besides regulations on mature content and mandatory airing of government messages, the existing bill includes broad prohibitions against "destabilizing" and "disquieting" content.

The Assembly will also propose a proposal for a single national Internet access point, "with a view to handling outgoing and incoming traffic in Venezuela"."

Laser 'tattoos' for labelling fruit

arielCo arielCo writes  |  more than 4 years ago

arielCo (995647) writes "Those helpful-yet-annoying little stickers on fruits that tell the cashier the variety and brand may be replaced with a CO2 laser etching. Quoth the PhysOrg article: "the laser cauterizes the peel, much like when a laser is used on human skin. The cauterized area is impenetrable to pathogens and decay organisms and resists water loss". Demonstrated on a grapefruit, it is due for testing on "tomatoes, avocado and other citrus fruits". The original paper (abstract) requires a paid subscription."
