Comment Re:jewelry website? (Score 1) 637

It's actually a reference to the (relatively?) well-known statistics website, which takes its name from the current number of electors (538...but it would be 436 without the extra two per state+DC). The existing website at that URL is probably a coincidence.

Comment Re:Current gen vs last gen (Score 1) 144

The rightmost digit was dropped from the 200 series when they reset the generation (leftmost) number, but the market position identifier has been in middle of the model number since the Geforce FX (5000 series), and it's always had roughly the same meaning. So the Geforce 7600, 8600, and 9600 were the same market position in their respective generations as the 260, 460, 560, etc, were (and it's THAT SAME market position that the 1060 occupies for Pascal). As far as release schedule, nVidia release order within generations for many years have been top-down except for the 9 market identifier, which launches late in order to double-dip from wealthy enthusiasts who might buy both the 8 and 9 cards from the same generation.

Comment Re:"US reactor" What exactly does that mean? (Score 1) 117

There are a tiny number of manufacturing facilities capable of forging single-piece reactor pressure vessels, and none of them are located in North America. I strongly suspect (but can find no clear references) that the pressure vessel in Watts Bar Unit 2 is from Japan Steel Works.

Comment Re:Cue the climate change deniers ... (Score 2) 684

"Ordinary" (orange-bulb) fire sprinklers are designed to trigger at 57C, and are rated for a maximum sustained ceiling temperature of just 38C. In buildings that are expected to get hotter than that, you're supposed to use red-bulb sprinklers, which trigger at 74C and are better able to deal with high sustained ceiling temperatures. It doesn't seem too unreasonable that someone in Rio was not thinking conservatively enough and installed the wrong kind of sprinkler heads.

Comment Re:Other: SeaMonkey (Score 1) 381

Many of us who use Seamonkey as our standard browser never switched to Firefox in the first place, because we thought (and still think) that even the original "stripping down" was going the wrong direction. It didn't BECOME a deficiency, it has always BEEN a deficiency.

Comment Re:Want people to know what they're doing online? (Score 1) 64

I think the browser you're looking for is Seamonkey. The status bar is always visible. The status bar shows exact link URLs. The URL bar shows the entire, exact URL, with the main domain in black and the rest in dark grey (same visual effect as bolding, but without changing character width, so it's easier to read).

The animals on the spacecraft were geckos, which certainly are lizards. There were no newts launched on Bion-M1, nor any other kind of amphibian.


Comment Re:CNC (Score 1) 514

Based on that analogy, the fastest result would not necessarily be from the most distant-efficient (offset) path, but possibly from an approach that was more aware of the limitations of the mower (turning radius, acceleration, and so on), like most modern HSM toolpaths. If the ratio works out the same as for, say, Volumill, then we'd want to increase the feedrate of our ordinary 10kph mower to, say, 40kph.

Now THAT would make mowing more fun.

Comment Re:Calculators (Score 2, Insightful) 1268

Or it could be a holdover from being taught to do longhand addition and subtraction chained vertically, like so:
- 54
which reads (out loud) very similarly to "123+456=579-54=525", which is, as the article points out, incorrect. Don't be too quick to blame calculators when longhand methods introduce similar errors.

Traveling With Tom Bihn's Checkpoint Flyer 133

Some people care about bags; obsession is a better word. (See the Bags subforum of the Every Day Carry Forums for evidence.) How are the straps attached? Is that 1050 denier, or 1600? Makers like Crumpler, Ortlieb and Maxpedition inspire impressive brand-loyalty, but probably no bag maker has customers more enthusiastic than Tom Bihn's. (There really is a Tom Bihn, too -- he's been designing travel bags since he was a kid; now he has a factory with "all the cool toys" to experiment with designs and materials.) When I started looking for a protective case for my MacBook Pro, I discovered that a few of my coworkers were part of the Bihn Army, and after some Tupperware-style evangelism I was convinced to buy a few items from the Bihn line-up: a backpack (used); then a messenger bag (new); then a mid-sized briefcase, used, which is now my portable filing cabinet. (Take this bias for what you will; I stuck with my previous messenger bag for more than a decade.) For a just-completed trip to Israel, which I couldn't quite make in true one-bag travel fashion, I brought along one of the newest Bihn Bags — the Checkpoint Flyer — and found it to be worth its (considerable) price. Read on for my review.

Submission + - How the City Hurts your Brain

Hugh Pickens writes: "The city has always been an engine of intellectual life and the "concentration of social interactions" is largely responsible for urban creativity and innovation but now scientists have found that being in an urban environment impairs our basic mental processes and after spending a few minutes on a crowded city street, the brain is less able to hold things in memory and suffers from reduced self-control. "The mind is a limited machine," says psychologist Marc Berman. "And we're beginning to understand the different ways that a city can exceed those limitations." Consider everything your brain has to keep track of as you walk down a busy city street: crowded sidewalks full of distracted pedestrians who have to be avoided; the hazardous crosswalks that require the brain to monitor the flow of traffic and the confusing urban grid, which forces people to think continually about where they're going and how to get there. A city is so overstuffed with stimuli that we need to constantly redirect our attention so that we aren't distracted by irrelevant things and this sort of controlled perception — we are telling the mind what to pay attention to — takes energy and effort. Natural settings don't require the same amount of cognitive effort and a study at the University of Michigan found memory performance and attention spans improved by 20 percent after people spent an hour interacting with nature. "It's not an accident that Central Park is in the middle of Manhattan," says Berman. "They needed to put a park there.""

GCC Compiler Finally Supplanted by PCC? 546

Sunnz writes "The leaner, lighter, faster, and most importantly, BSD Licensed, Compiler PCC has been imported into OpenBSD's CVS and NetBSD's pkgsrc. The compiler is based on the original Portable C Compiler by S. C. Johnson, written in the late 70's. Even though much of the compiler has been rewritten, some of the basics still remain. It is currently not bug-free, but it compiles on x86 platform, and work is being done on it to take on GCC's job."
