In Topic: Its Just Me That Cant Change Currency On Amazon Orders?

Today, 03:54 AM

If I recall correctly, when you go to "check out" (but before hitting the "OK" button), it shows the amount in local currency. For what it's worth, anyway.

That's without local Mafia fees. Those come as a bonus surprise when you don't get your parcel delivered, but instead get a postcard dated back 4 days saying "come and get it within 5 days, at our office in a town 50 kilometers away". And then it turns out that you have 20€ free, but your book which was 19 something coes out at something 21.50 including shipping, so you have to pay 0.01 of import tax, which takes about 15 minutes and filling out two A4-sized forms (at least those are on recycled paper), and you get a flipping receipt on another (no-recycle) A4 sheet of paper for having paid 0.01 of import tax.

In Topic: Flying Inside A Rotating Torus Space Station (Artificial Gravity)?

Today, 03:36 AM

Someone in the middle of the space station will have no artificial gravity, as the wheel isn't pushing them around. Actually, anyone not moving with the wheel with have no artificial gravity.

This.

Though it's only 99.975% correct. There will be airflow caused by the rotating torus. Laminar flow, oh the joy. That means fastest flow near the floor with quadratic or something (cubic??? I actually forgot how this worked...) falloff, and practically standing still in the middle (at reasonable rotational speeds anyway, it is possible to have the air in the middle flowing noticeably, too... I wouldn't want to be in there, however).

That flow will drag you, or any inanimate objects, around. While it will almost certainly be too weak to drag you onto a circular path and generate artificial gravity, it will however drag you somewhere. The fun part is that since we're talking of a torus, it is not immediately obvious where. Chances are, however, that with some luck you hit the floor eventually. At least as long as you are very slightly over the middle, it will only ever drag you into faster flowing regions. But I guess even on the "inside", your inertia should be able to bring you there, eventually (within some days).

In Topic: Statute Of Limitations Justifications Making No Sense

It makes sense outside "crime", and there is a very similar concept.

There is the saying when a 90 year old dies: "I guess we can't blame the midwife for it". As often with such sayings, there is a lot of truth (and common sense) in that. There would be no end to senseless trials if every claim remained valid forever. The "you did not bother during the last 10 years, why now" defense is very valid.

Except, when it comes to "crime", I think ther should be no free lunch, especially since it sometimes takes victims a long time to even step forward (think rape) or the victims may be entirely unable to do so (think murder) and it may take the police years to pin the culprit down. Double jeopardy is a similar thing. While the initial idea (protect the citizen from e.g. politically motivated infinite arrest-trial cycles, which is basically the same as being in prison for life) is a good intent, overall it is a very bad thing. It means that someone who is entirely guilty walks free for a trifle, and even if enough conclusive evidence is found thereafter to nail him down, he still walks free.

Speaking of crime, the above example of not paying your tax is somewhat bad, I think. If you didn't pay your tax, you still owe the state money, and interest. But it is not a crime (factually, it is -- but it should not be). This is one of these examples of needlessly criminalizing the "good" citizen. There are people in Germany (the father of S. Graf being a prominent example) who spent more time in prison for not paying tax than some murderers. This cannot possibly be considered fair, but the length of the sentence is not where it ends.

Criminalizing someone means in all likelihood that they lose their job and will be unable to get hired again. Not in any respectable job at all anyway, and often not in any other job either. If being caught cheating on your tax simply meant you have to pay your tax debt plus a small "extra fee" to account for the interest (say, three times your original tax debt) it would be better for everybody. A useful member of society remains a (now tax-paying) useful member of society instead of costing money to be emprisoned and living off wellfare afterwards. Plus, the state gets a little extra money. Win-win in every respect.

That is true even more so as the taxation system is so deliberately complicated (apart from justifying a huge, decadent administrative machinery, my theory is that this done to ensure that practically every average citizen is guilty of something) that you must either hire a tax accountant or have a degree in that field, if you don't want to risk doing it incorrectly by accident.

In Topic: Vulkan is Next-Gen OpenGL

As for Async; firstly it seems that pre-Pascal forget it on NV. If they were going to enable things to work sanely on those cards they would have done so by now

It's not so much limited to async compute, but to compute and transfers in combination alltogether it seems.

I can confirm that from my immediate experience with using Blender (which on NV uses CUDA) on a desktop computer with a Maxwell GPU in comparison to my notebook which only has the Skylake CPU's integrated graphics chip.

Yeah, Blender on a notebook, and setting the 3D viewport to "render", what a fucked up idea, this cannot possibly work. Guess what, it works way better than on the desktop computer with dedicated GPU.

Now looking at the performance counters shown by process explorer, it turns out the Maxwell has two shader units busy on average (two!) whereas the cheap integrated Intel GPU has them all 95-100% busy. So I guess if the GPU does not spend its time doing compute, the time must go into doing DMA and switching engines between "transfer" and "compute". Otherwise I couldn't explain why the GPU usage is so darn low.

Now, since this is not an entirely unknown issue, I would seriously expect Pascal schedule/pipeline that kind of mode switching much better, or even do it in parallel seamlessly (I think I have read something about them adding an additional DMA controllers at one point, too, though I believe that was even for Maxwell -- would make seem on yet older generations it's still worse?).

In Topic: Trump Is The Republican Candidate - Now What?

21 July 2016 - 04:15 PM

so I've not voted for any one in 17 years because of that view.

Well, that is bad. If you don't vote (...especially if many do that), it is the rule of few. I am voting even though right now I know that I am voting wrong. Been voting "conservative" for 28 years, now I vote "Anti-EU" although I am as much "pro-EU" as one can be. But it is the only thing I can vote, and the only leverage I have against the politicians is that one vote. There is no "middle", no "conservative" that I could vote.

Voting wrong is in most cases still better than not voting at all. It is the only thing you can do to show your politicians that they are on the wrong path. Only if another party starts gaining percentage points in the two-digit range, they start to think that maybe, only maybe they might do something wrong.

Yes, there is the risk that you vote for someone you didn't want, and surprise, they actually win. Well,that's bad, but it is still better than doing nothing and letting the minority that votes decide for you. Besides, people have died so you have the right to vote, which is by itself a reason not to throw that right away.

Back to the original question, Trump and how much he can make the world worse: I've read on teletext that he wants to turn NATO into an non-reciprocal thing. As in, everybody has to help the US of course, but if someone else is attacked, Trump will first decide if they are worthy. Now that's a really good plan. Make friends early, eh :)

Meanwhile Erdogan's witch hunt against Gülen (is that his name?) supporters is international. It's like 1933, only we now have young-male-Turk mobs, not the SA in the streets. Oh, and they make videos with their smart phones (hey, and why not make a fun video of some good violence, nothing to be afraid of, nobody will go to jail or be expelled!). There's even a hotline to denounce people so the attacks can be coordinated. The paroles are like "show me them so I can bathe in their blood". Very civilized. And that AKP guy on Maybritt Illner of course denied everything (what else).
