Comment Re:massive parallel processing=limited application (Score 1) 102

On a 8-core machine, a processor will be placed into a wait queue roughly 7 out of 8 times that it needs access.

You just snuck into your analysis the assumption that every core is memory saturated, and I don't think that all the memory path aggregates in many designs until the L3 cache (usually L1 not shared, L2 perhaps shared a bit). The real bottleneck ends up being the cache coherency protocol, and cache snoop events, handled on a separate bus, which might even have concurrent request channels.

I think in Intel's Xeon E5 line-up there are single-ring and bridged double-ring SKUs for forwarding dirty cache lines from one cache to another (and perhaps all memory requests). This resource can also drown for many workloads.

In many systems, you have all these cores running tasks which are fairly well isolated (not much cache conflict), except they all want to be able to allocate as much memory as they need from a giant memory space (e.g. a TB of DRAM) so they fundamentally have to fall through to a shared memory allocation framework.

You can learn a lot about the challenges involved by following the winding path of something like jemalloc as increasing concurrency levels expose yet another degeneracy.

The real problem with this field is that there isn't a single, simple story like the one you tried to tell. There are usually dozens of ways to skin the cat, each with completely different scaling stories, with different sets of engineers who are good as tweaking or debugging those stories.

At this point, what you have is a fragile coordination problem between your solution space, your architecture, and the engineers you employ, forcing ambitious ventures to crack out the golden recipe: pour in seven cement mixers full of head hunters, one 55-gallon oil drum of exclamation marks, a metric butter tonne of job perks, and agitate appropriately.

Here's cash flowing into the Clinton Foundation from corporations benefiting from selling dual use technology [nypost.com] (private and military uses) to Russia.

In case you haven't noticed, most of our "dual use" technology has been shared with the Russians for a long time already. For example, the decimal number system.

In some instances, we might even consider ourselves better off if the Russians did choose to adopt our technologies, such as fail-safe command and control systems responsible for nuclear weapons (supposing our technology is actually better; I suspect the Russians have had 8" floppy disk drives for quite a while already).

Just about any improvement in the Russian commercial space would probably trickle down to the Russian military (trickle down seems to work much better in some directions than others). Are we still in the middle of a 1950s-style total economic blockade? Not that I've heard. Our bigger technical battles are with countries who have not yet produced thousands of nuclear warheads.

In summary, all of this is all a lot of hand-wavy durf, durf, durf.

Point to a real technology and describe an actual scenario where the Russian military benefits, and then explain how the Russian benefit A) is a serious NATO concern, and B) wasn't going to happen anyway sooner rather than later. Having met that bar, then maybe this issue will start to seem important to people outside your particular Kool-Aid enclave.

Penn Jillette on Donald Trump, Hillary Clinton, And Why He's All in on Gary Johnson — 2 August 2016

I watched this video yesterday. There a fabulous exchange 24:30–30:00 on truth and naievity.

You go through a period when you're sixteen, seventeen, eighteen when truth really obsesses everybody. And then I think you're supposed to kind of sort of grow out of it. And I didn't. It really remains of complete interest to me. ... I'm not bothered at all by people being wrong. ... I have such a naive point of view, to almost not believing it, that people can have information and represent the opposite of that. I just find that so appalling and, in a certain way, fascinating.

Once upon a time I would have ventured that most Slashdot readers would want to view this. It had me thinking about my own life 1985–1995 where I watched the software industry turning into a train wreck, where every seventh train car is painted bright orange and lettered in an ominous Area 51 black stencil font "patch Tuesday", with sparks flying off wheels seized (and reseized) for so long they resemble lopsided pentagons.

I used to think to myself "surely these are just temporary conditions due to the extreme rate of expansion of the software industry, and it will all settle back down to sanity as we crest the exponential growth phase". But no. Like Jillette, I was a die-hard naievitarian. Lesson learned.

The default behavior is to treat the field as whatever you've told the spreadsheet that it is. By default, every cell is set up for numeric data types. ... The problem is misuse of tools, not a problem with the tool.

A process of "five whys" applied to the present discussion immediately reveals "default numeric" as bad policy in academic research.

A sane default would be "untyped" or "exactly as entered" which shifts sins of omission into sins of commission, this being far more compatible with the culture and standards of scientific journal publication than what Microsoft originally chose, mainly for the convenience of boutique-reseller power demos.

The Not-So-Great Professor: Jeffrey Sachs' Incredible Failure to Eradicate Poverty in Africa

The early sections of Nina Munk's book about the economist Jeffrey Sachs read like a celebration of a boy genius. No, strike that: Sachs piles up so many achievements so quickly that the word genius sounds somehow inadequate.

By the age of 13, he was taking college math. Later, he got near-perfect scores on his SATs and graduated summa cum laude from Harvard, where by 28 he was a tenured professor. Two years later, he was advising the Bolivian government on how to administer economic "shock therapy," designed to break the spell of hyperinflation. This led to an even bigger triumph: masterminding Poland's transition to a market economy in 1989, as communism collapsed in Eastern Europe.

Like most geeks, never seen a system he couldn't fix better. Until something blew up so spectacularly, he either got the grey beard gene forever, or curled up and hid in a closet somewhere.

Of course, if you watch enough superhero movies, you just need to put the word out ("the system is broken!") and somehow Jeffery will get the bat signal, and he'll patiently hand-stitch some brightly coloured, stretchy fabric (you'd be amazing what else he found in that stiff bottom drawer with all his grandmother's old Jane Fonda work-out videos) into the peacock man-cape he always dreamed about while he was acing his SATs (painstakingly ripping and replacing the crotch seam six times to achieve the optimally brash yet task-focused fit—they don't call him "Dr Sacks" for nothing) and then he'll spring out the window, and who knows, maybe he can actually fly. I guess we'll find out.

MaxMind didn't send all those yokels off on spurious missions. Are you your brother's keeper?

It's not a simple legal argument, here. You have to argue that MaxMind should have had a reasonable expectation that yokels will be yokels.

The next step in the argument, it seems to me (I don't give a shit that IANAL), is to claim that enabling yokels to be yokels is an explicit element of the MaxMind value chain, from which MaxMind extracted all kinds of proceeds.

Then it could be argued that this was such an integral element of their value chain as to have induced them into invented a "not found" representation which masqueraded as a valid search result, so as to deliberately create a superficial impression that "not found" results hardly ever happen. That would be the strong condition, but hardest to establish. MaxMind will counter that this was a merely a technical felicity, and that it's no crime to be lazy.

In the strong condition, I see it as absolutely the case that MaxMind sought gains from negligent asshattery.

I also think there's a good chance this case can't demonstrate the strong condition, and only a modest chance they obtain damages from the mild condition.

If MaxMind has a moral backbone, they'll settle out of court for a conscionable amount, unless the aggrieved are in full-on casino mode.

The aggrieved definitely deserve compensation here, but if they have to collect directly from the yokels who caused the disturbances, good luck with that.

Let's take a closer look.

Harper v. Virginia State Board of Elections

In a 6 to 3 vote, the Court ruled in favor of Ms. Harper. The Court noted that "a state violates the Equal Protection Clause of the Fourteenth Amendment to the U.S. Constitution whenever it makes the affluence of the voter or payment of any fee an electoral standard. Voter qualifications have no relation to wealth."

This ruling reversed a prior decision by the Court, Breedlove v. Suttles, (1937), which upheld the state's ability to impose poll taxes as within its powers. There had been no relevant change in the text of the Constitution between 1937 and 1966.

The 24th Amendment, adopted in 1964, outlawed the poll tax in federal elections, but did not speak to the question of state elections, which was the question involved in the Harper case.

The Court membership had changed, and the justices examined the issue from a different point of view.

So, you're right after all: if it was unconstitutional then, there's no reason it shouldn't be unconstitutional now, modulo the penchant of justices of the U.S. Supreme Court to dye their wigs different colours in different eras.

So if the California situation were to go to the U.S. Supreme Court, the court would probably look at the three dissenting opinions from Harper, perhaps choosing a point of view that takes those arguments even more seriously than the last time around.

Slam dunk. No need to huddle around the Vatican chimney, or any of that rot.

If the headline tells me how anyone feels (myself, the photographer, the poster, the subjects of the video, the bystanders in the video, or God himself) then the video is a 100% no fly zone.
