NVIDIA Releases Fix For Dangerous Display Driver Exploit

ATMD Re:No it didn't (84 comments)

Would you sell a product that shot out fire if someone clicked a slider setting too high?

I have one of those, I use it for sticking bits of metal together.

Ask Slashdot: Why Does Wireless Gear Degrade Over Time?

ATMD Re:Signal isn't chaning, the noise floor is (615 comments)

If you read the OP carefully, all he says is that he replaced the routers - not that doing so actually fixed the problem.

Deteriorating SNR does seem the most likely explanation.

BT Fibre Pulls Out of Chelsea Over Ugly Equipment Cabinets

ATMD Re:Agreed (136 comments)

I was on UKFSN when I lived with people, but had to switch to a cheaper ISP when I started living on my own. If I could afford it I'd definitely go back, though - proper business-grade ADSL, a /29 subnet, fantastic latency and great customer support (it's run by a geek in his garage).

That was a couple of years ago so it may have changed, but I'd certainly be willing to try them again if I had the chance.

Richard Branson Announces Virgin Oceanic Submarine

ATMD Re:37,000 feet deep? (122 comments)

It may be able to withstand static pressures at the ocean's deepest points, but as soon as you start moving you get dynamic pressure from the bow wave at the front. If it was going fast enough, it could easily experience a pressure head of more than 37000 feet at the nose. Plus, craft like this will be built with a decent safety factor, hopefully at least 2.0, so the people inside it don't die if the engineers get their maths wrong.

Feds Bust Cable Modem Hacker

ATMD Re:What!? (658 comments)

Noone should be coerced into pleading guilty. Imagine he was innocent, but unfortunate enough to have the evidence against him. Now he either confesses to a crime he didn't commit, or gets convicted of "felony commercial burglary", a crime much bigger than the one he didn't commit.

32 Exoplanets Discovered By Chilean Telescope

ATMD Re:3.5km/h (146 comments)

I was reading the summary thinking "surely a telescope's sensitivity should be measured in arcseconds, and the minimum detectable speed should be in arcseconds-per-second rather than miles per hour." Of course they were talking about bodies moving toward and away from us, rather than across our field of vision, so it's a Doppler effect measurement rather than looking at a picture and saying, "hey! That bit moved!"

I've just had my big mug of coffee, but obviously it hasn't reached my brain yet :)

Gene Roddenberry's Mac Plus Is Coming Up For Auction

ATMD This is nothing. (162 comments)

Apple may have given Roddenberry a Mac, but in a decade or so they'll be celebrating Asimov's 100th birthday with their new media-streaming, music playing domestic assistant, the iRobot.

The Orange Goo That Could Save Your Laptop

ATMD Re:I don't get it.. (285 comments)

Nice analogy =P

I'm tempted to improve that Wiki article on power-law fluids when I have a moment, so that it's more readily understood by those who haven't already learned the majority of what it's trying to explain...

The Orange Goo That Could Save Your Laptop

ATMD Re:I don't get it.. (285 comments)

Heh, glad I put that disclaimer there. Stopping force is proportional to velocity, (technically shear rate), in a Newtonian fluid such as water or oil: in a shear-thickening fluid viscosity is proportional to velocity. Viscosity is the proportionality constant linking speed and stopping force, so I guess that makes stopping force proportional to the square of the speed.

For more info, try these.

The Orange Goo That Could Save Your Laptop

ATMD Re:I don't get it.. (285 comments)

I guess there's a limit to the amount of shock it can absorb. I would imagine its properties have been tweaked so that it stops any impact within its own thickness. Obviously if the impacting object is travelling faster, that results in more rapid deceleration and thus more forces transferred to the delicate internally-bits of your laptop. For dropping off a table though, it probably provides the smallest possible deceleration force against the floor, compared to protection materials currently on the market.

My suspicion would be that rather than rather than causing the linear deceleration of a simple spring constant, (like most other foams, rubbers, etc.), it provides an exponential deceleration: the stopping force in a shear-thickening fluid is proportional to the speed rather than the displacement. This means that the material starts acting from the very moment of impact, as that is the point with the highest speed. A spring, (or foam, or rubber, or anything else that acts like a spring), would do essentially nothing until the impact has squeezed it enough to get a decent counter-force out of it. But by that time it might be too late, and the spring might have already bottomed out. I'd be interested to see some numbers for this gel, to back up the stuff I've just written!

Browser Vendors Force W3C To Scrap HTML 5 Codecs

Chodeaphone? What?

If you're going to alter a company's name for ironic effect, at least do it in a way that makes sense. Personally I find it immature and annoying, and wish people wouldn't do it at all.

Obama releases iPhone app

ATMD ATMD writes  |  more than 5 years ago

The BBC is reporting on a new iPhone app from presidential candidate Barack Obama, to help you organise your own personal mini-campaign of friend-badgering. It sorts people by state, and by their "Obama status" - how favourably they're thinking of him.

Of course this begs the question of whether any potential McCain app will be allowed, considering Apple's infamous "non-competition" policy...
