Submission + - NVIDIA's G-Sync Is VSync Designed for LCDs (not CRTs).

Phopojijo writes: A monitor redraws itself top to bottom because of how the electron guns in CRT monitors used to operate. VSync was created to align the completed frames, computed by a videocard, to the start of each monitor draw; without it, midway through a monitor's draw process, a break (horizontal tear) would be visible on screen between the two time-slices of animation.

Pixels on LCD monitors do not need to wait for above lines of pixels to be drawn, but they do. G-Sync is a technology from NVIDIA to make monitor refresh rates variable. The monitor will time its draws to whenever the GPU is finished rendering. A scene which requires 40ms to draw will have a smooth "framerate" of 25FPS instead of trying to fit in some fraction of 60 FPS.

I'm 6'7". I do my best not to fly (don't really want to be sexually abused) but when I have to, I am fucking miserable.

Yeah, tell me about it. I'm 6'4" (plus a 1/2" extra in the morning) but I have an especially long torso, so we'd probably be eye to eye sitting down. I don't know about you, but the seat in front of me prevents me from slouching the least bit, when I lean my head back on the head rest, my gaze is vertical. It's pretty close to a 90 degree bend, which I try out just for shits and giggles, while other people find ways to sleep.

Pro tip for tall fliers: the foam cushion usually rips off the aluminum seat frame (Velcro). If your ass can handle sitting on the hard, cold metal you might manage enough of a head rest to get a half hour snooze in the mid-flight red-eye hour of total desperation. I've done this many times.

I got stuck on the apron at Schiphol once while they replaced a starter motor. The middle-aged Germanic woman beside me had tree-trunk thighs, clad in tight black neoprene. Our thighs met in a thermonuclear embrace on my side of the arm rest for our entire stay on the apron, plus the return flight to Montreal.

At this point, the airlines can go fuck themselves. I'd rather not leave the ground.

Submission + - Eureka! An Unexpected Ray Of Hope For Americans And Scientific Literacy! (politico.com) 1

An anonymous reader writes: Politico reports, "A finding in a study on the relationship between science literacy and political ideology surprised the Yale professor behind it: Tea party members know more science than non-tea partiers. Yale law professor Dan Kahan posted on his blog this week that he analyzed the responses of more than 2,000 American adults recruited for another study and found that, on average, people who leaned liberal were more science literate than those who leaned conservative. However, those who identified as part of the tea party movement were actually better versed in science than those who didn’t, Kahan found. The findings met the conventional threshold of statistical significance, the professor said. Kahan wrote that not only did the findings surprise him, they embarrassed him. “I’ve got to confess, though, I found this result surprising. As I pushed the button to run the analysis on my computer, I fully expected I’d be shown a modest negative correlation between identifying with the Tea Party and science comprehension,” Kahan wrote. “But then again, I don’t know a single person who identifies with the tea party,” he continued." — More at the Independent Journal Review.

Submission + - New EU Rules To Curb Transfer Of European Data To The U.S. (theguardian.com)

dryriver writes: The Guardian reports: New European rules aimed at curbing questionable transfers of data from EU countries to the US are being finalised in Brussels in the first concrete reaction to the Edward Snowden disclosures on US and British mass surveillance of digital communications. Regulations on European data protection standards are expected to pass the European parliament committee stage on Monday after the various political groupings agreed on a new compromise draft following two years of gridlock on the issue. The draft would make it harder for the big US internet servers and social media providers to transfer European data to third countries, subject them to EU law rather than secret American court orders, and authorise swingeing fines possibly running into the billions for the first time for not complying with the new rules. 'As parliamentarians, as politicians, as governments we have lost control over our intelligence services. We have to get it back again,' said Jan Philipp Albrecht, the German Greens MEP who is steering the data protection regulation through the parliament. Data privacy in the EU is currently under the authority of national governments with standards varying enormously across the 28 countries, complicating efforts to arrive at satisfactory data transfer agreements with the US. The current rules are easily sidestepped by the big Silicon Valley companies, Brussels argues. The new rules, if agreed, would ban the transfer of data unless based on EU law or under a new transatlantic pact with the Americans complying with EU law. 'Without any concrete agreement there would be no data processing by telecommunications and internet companies allowed,' says a summary of the proposed new regime. Such bans were foreseen in initial wording two years ago but were dropped under the pressure of intense lobbying from Washington. The proposed ban has been revived directly as a result of the uproar over operations by the US's National Security Agency (NSA).

Don't use a programming language. Use a tool like Matlab or Mathematica instead. These tools are well designed for scientific computing and have sufficient scripting built in to support the programming-language-like functionality you're probably looking for.

You won't be able to call yourself a programmer. But you're not a programmer, you're a scientist.

Not so you can do it yourself: by now you know what work you like to do. Why rob yourself of what makes you happy?

Learn so you can understand the folks you work with for whom the business side is their source of joy. They'll notice. And enough of them will repay the favor to expand your opportunities to do the work *you* enjoy.

now operating mostly beyond its original 40-year licenses

What do 'best before' dates on food really mean?

Some number pencilled into an operating permit granted in 1969 is not the last word on how long these facilities will continue to operate safely.

There was—at the time—not a single reactor of a modern design with a forty year operational record on which to base even the wildest guess. The number "40 years" had more to do with investor ROI than any engineering crystal ball.

I recall one reactor shut down for an expensive refurbish a long time ago because circulation pipes had become unexpectedly brittle in less than a decade of exposure to a constant, low level of neutron flux.

Summary: we didn't know shit.

On day one, it's extremely hard to tell the difference between a Toyota and a Chevy. At year thirty, the stakeholders think they've won the lottery because it was a Toyota after all. At year thirty-five, Toyota develops a frightening latency in response to the graphite rods. At year forty-two you've got this headache sorted—or so you would like to believe. It was operator over-reaction to upgraded SCADA data collection rates. No, it was xenon capture by surface pockets in metals exposed to decades of micro-crystalline annealing. No, it was pockets of non-uniform fission density due to a very minor change in the fuel-pellet binding agent made as older mines ceased production.

All the reactors built in the 1970s were version 0.9. No reactor anywhere had a forty year operational track record with a modern design.

Now for a side rant. Suicide is a pussy way out.

That's a common meme for people that don't know the psychology of suicide. Suicide generally takes a fair bit of strength of character. The problem is not being "a pussy" or "taking a pussy way out" - it's an unfortunate evaluation, often from wrong premises. A common one is that a bunch of psychological or life situation issues are permanent/long term, while they are usually possible to change. Another is overestimating how much the person is a burden to other people in their lives, and wanting to lighten their load.

As to his comment about turning over the master key, it would have made no difference if they had protections on their master key

If they had designed the system to not have a master key, such that each user had their own keypair and each user had sole possession of their specific decryption key then they would have been immune to the insiders - cartels or DoJ.

Indeed, especially since the skills of programming a mechanical engine go many eons farther back with, I believe, the invention of the loom. The result was somewhat different (a woven pattern, rather than a scalar value), but the idea of a set of sequentially executed instructions with loops, counting variables, and exceptions, started a long time before Babbage. Knitting and crocheting is rather quite similar, and embodies similarily pre-existing art, as well.

Submission + - Ed Felten: Why Email Services Should be Court-Order Resistant (freedom-to-tinker.com)

Jah-Wren Ryel writes: Commentators on the Lavabit case, including the judge himself, have criticized Lavabit for designing its system in a way that resisted court-ordered access to user data. They ask: If court orders are legitimate, why should we allow engineers to design services that protect users against court-ordered access?

The answer is simple but subtle: There are good reasons to protect against insider attacks, and a court order is an insider attack.
