Fake Engine Noise Is the Auto Industry's Dirty Little Secret

xfade551 Re:Just give the option to turn it off... (820 comments)

I drive a vehicle with a modern V-8 Hemi. It's incredibly quiet, except when I really stomp on the gas, and even then it's not that loud. I suppose I could swap the exhaust for Magnaflows or something, but it's kind of fun having a sleeper vehicle, especially when a couple tricked out Hondas pull up on you on the freeway when you're already doing 70mph at merely 1600 rpm.

SpaceX Landing Attempt Video Released

xfade551 Re:parachute (248 comments)

The shuttle's Solid Rocket Boosters always had a bunch of salt water damage that had to be cleaned up and refurbished before being reused, and that refurbishment process costs only slightly less than manufacturing from scratch. The Falcon 9 is a liquid fuel rocket, so that same saltwater has even more things it can damage like pipes and pumps. SpaceX is trying to avoid any major saltwater clean-up, yet still have a place to put the rocket down that's unlikely to hurt anyone when the landing still fails every so often: "Oops, I guess that part was only good for 6 landings, not 7", "Crap, the forecast was wrong! The rocket is now incoming and we got high winds", etc.

There's a Problem In the Silk Road Trial: the Jury Doesn't Get the Internet

xfade551 Re:Jury of your peers (303 comments)

That you have a right to a "Jury of your peers" is a misunderstanding; it is nowhere in the U.S. Constitution. That concept was a British common law one, established by the Magna Carta, wherein nobles would be tried with a jury composed of nobles, and commoners with a jury of commoners. Since titles of nobility, etc. are blocked by U.S. Constitution, that means everyone is a "commoner", so everyone is your peer.

However, if I ever found myself being prosecuted, I would certainly much rather the jurors be composed largely of engineers and similar professions, but those tend to get booted during jury selection (lawyers don't like people who can see through their bullshit).

How Close Are We To Engineering the Climate?

xfade551 Re:Summary video (319 comments)

The deep ocean, where the clathrates are (because methane requires high pressure to hydrate in the midst of liquid water) really doesn't have much variation in temperature. Water, salt water included, is at it's densest at just a few degrees above it's freezing point, so you get an approximately constant temperature at the bottom (neglecting thermal vents and thin areas of crust, and the like). Tectonic/volcanic events are much more likely to release the stuff, and we don't have much control over that (okay, there is some debate about oil fracking, but that is land-based).

With respect to the "exponential system", the old "hockey stick" graph has been repeatedly shown to be false. Not to say there is no warming going on, but whether it's linear, exponential, or cyclic has yet to be proven. I'm more inclined to lean "cyclic" as there have been multiple ice ages and warming periods. Anyone know of any studies that have run Fourier Analysis/FFTs on climate data?

Spraying sulphur in the atmosphere in a warmed up Earth? Are they trying to recreate Hell?

"They" aren't, but the summary writer sure is.

EFF: Apple's Dev Agreement Means No EFF Mobile App For iOS

xfade551 Publicity stunt (220 comments)

They sat down at a meeting, Junior PR Guy: "We should make some mobile apps!"
Senior Manager: "That's a great idea!"
Principle Lobbyist: "Apple's TOS sucks, we can't do that!"
Senior PR Guy: "Wait, wait... we can use this. We'll do the Android app, then make a public complaint that we can't release the iOS app because of Apple's TOS. But we don't actually have to build the iOS app."
Senior Manager: "I approve, go for it!"

Ask Slashdot: High-Performance Laptop That Doesn't Overheat?

xfade551 Thermodynamics (325 comments)

A laptop is a hard thermodynamic environment. There's not much space to move air around, so with the low volumetric air flow rate, you get lower heat exhaust, so the internals tend to get hot. The hotter the components get, and the more often they stay that way, the more likely you are to get failures due to heat fatigue, which is pretty much inevitable with any laptop. If portability is required, you are pretty much stuck dealing with the issue, otherwise get yourselves some desktops (if still necessary, you can add water- or cryo- cooling to a desktop).

CIA on UFO Sightings: 'It Was Us'

xfade551 Re:What about "The Day After Roswell" book? (197 comments)

Do you realize that 200 years ago was still 10 years after the first railway journey, 21 years after the first untethered flight of a hot air balloon, that weaponized rockets were in common use by British armed forces and others (later inspiring Jules Verne to write science fiction about going to the moon), and that early versions of electrical telegraphs were in testing?

Putting a MacBook Pro In the Oven To Fix It

xfade551 Re:Macs Don't Seem To Handle Heat Well (304 comments)

I had a Radeon card fry in a PowerMac G5 (1st gen) several years back... at first I thought I had an electrical fire in my house. I'm pretty sure in that case it was the fan on the card that failed, as by the time I extracted it, the heat sink had warped and peeled halfway off the GPU chip. I ended up putting the OEM card back in, and donating the machine to my church, where it is still going strong to this day.

Is the Tablet Market In Outright Collapse? Data Suggests Yes

xfade551 Re:Phone costs (328 comments)

The cost of a large smartphone is hidden by the contract. With a tablet you pay full price up front.

Unless of course, Verizon throws in a tablet for an extra $0.02 up front and $10/month on your data plan when all you went in to do was replace your 3.5 year old phone. Sold.

Colorado Sued By Neighboring States Over Legal Pot

xfade551 Re:Hope they win this case. (484 comments)

Maybe because white guys arent pointing the long guns at cops.

Mostly true, but more true is that when a white (or any race) guy with a gun points said gun at the cops and gets shot by the cops, other white guys with guns usually say, "Dumbass! What the hell was he thinking would happen!?! Better nominate him for a Darwin Award!"

This is neglecting now too frequent edge cases like "cops get warrant for wrong house, homeowner dies in ensuing firefight" or "child with obvious fake gun gets shot by police"

Colorado Sued By Neighboring States Over Legal Pot

xfade551 Re:Dry Counties? (484 comments)

"I don't care if you go to Colorado and smoke pot, but it's still illegal here and if I catch you with it, I have to arrest you." Law enforcement officers I know are mixed on whether they think pot is okay or not, but they all agree that if you're caught with it, they can't just let you go.

But the police have argued all the way to the Supreme Court that "discretion" is a right of the cops, and they are *never* required to enforce any law.

I'm pretty sure the GP was speaking with officers working the beat, not the city police chief, county sheriff, or prosecutor, in whom that full discretion actually lies. "Don't let marijuana violators go, or else you lose your job" is pretty strong motivation to enforce.

Integrated Circuit Amplifier Breaches Terahertz Barrier

xfade551 Re:Not solid state... (81 comments)

There are two articles linked. The first article is about a new integrated circuit amp. The second is about a year old and is about a separate vacuum tube amp. The first article mentions that the new IC amp broke the record of the earlier vacuum tube amp. So, for once, the summary is correct.

Employers Worried About Critical Thinking Skills

xfade551 Re:Want Critical Thinking? Fix the Public Schools (553 comments)

What sane American would take a public school teaching position if they can get a better deal doing something else?

I think I'll let the above question stand on it's own.

Anyway, I regard Meyers-Briggs as a tool, rather than anything mathematically perfect.

By the way, I don't really care if you're rude or polite. This is Slashdot, after all!

Employers Worried About Critical Thinking Skills

xfade551 Re:Here's one reason (553 comments)

We caucus in my state (Washington) during Republican primaries, rather than a wider public vote. The Democrats hold a very solid majority outside my career field, both in the local area, and state wide. Our local representative in the State Legislature is a Republican and a few county or city officers are, but that's about it.

Employers Worried About Critical Thinking Skills

xfade551 Re:Want Critical Thinking? Fix the Public Schools (553 comments)

I think part of the problem is a lot of people who are attracted to the teaching field tend to be ESFJ-Meyers-Briggs personality type, which, in the first place, tends not to be the best personality for participating in critical thinking.

Employers Worried About Critical Thinking Skills

xfade551 Re:Here's one reason (553 comments)

This is anecdotal, but the sample size is still fairly large: The vast majority (~75%) of U.S. engineers (not counting software developers, we don't have many of those around here) that I know and work with (figure around 500) are left of center and tend to vote Republican, a lot of those having been leaning Tea Party or Libertarian lately, and hate what the Neo-Cons have done. Those that vote Democrat usually come from families that have strong labor unions ties, but seem to be fairly moderate to conservative otherwise; they are also usually the ones that like to stir up debate and play devil's advocate, but what engineer doesn't like debate and/or arguing from time to time?

Independent Researchers Test Rossi's Alleged Cold Fusion Device For 32 Days

xfade551 Re:Hoax (986 comments)

The scientist that examine it did a little bit more than look at it, but the most telling note in the linked paper is "Considering that we do not know the internal structure of the reactor, and therefore cannot completely rule out that there were other charges inside it besides the one weighed and inserted by us, " which was exactly my thought after reading the summary.

Physicists Find Clue as To Why the DNA Double Helix Twists To the Right

xfade551 Re:Orientation (120 comments)

As someone else posted above, if you look at it from the opposite direction, it still twists right.

Find the nearest screw or bolt (almost all will be right-handed), pick an end to be up, point your right thumb in that direction then curl your fingers: your fingers will curl in the same direction that is needed to move up the spiral. Now flip the bolt or screw upside down and try it again... Yep, still works. Now try it with your left hand: your fingers will curl in the downwards direction. That is what is meant by right-handed or left-handed.
