Is Carbon Fiber Going Mainstream?

thelovebus Re:It already is - for bicycles (152 comments)

There'll be plenty enough weight to corner safely, even with a full carbon monocoque, for passenger car driving.

Extra downforce is really only needed on racing cars.

Desert Farming Experiment Yields Good Initial Results

thelovebus Re:Why those vegetables? (178 comments)

Do you really think the amount of oil used to transport vegetables (even multiple years-worth) is greater than that used to build those greenhouses? The great cost in shipping a bushel of tomatoes a few thousand miles isn't wrapped up in the oil, it's the logistics/storage/refrigeration/etc.

NHTSA Gives the Model S Best Safety Rating of Any Car In History

thelovebus Re:Model S vs Hummer (627 comments)

You seem to be overlooking a fairly crucial factor: Because the Model S has a halfway decent suspension and modern features such as traction control, the driver should be able to maneuver the car quickly enough to *avoid* a head-on collision. Why would you possibly think it's more important to optimize safety around an unlikely scenario like "head-on collision with a Humvee", than to avoid the accident altogether?

Also, I'm fairly certain tanks, semi-trucks and airplanes don't get to qualify for the "safest car ever" award, since, you know, they're not cars! Also, I think an airplane fares even worse than a typical passenger car in your contrived "head-on collision with a humvee" scenario.

NHTSA Gives the Model S Best Safety Rating of Any Car In History

thelovebus Re:NHTSA pushed a 5 star rating (627 comments)

I'm fairly certain that a roof that *doesn't* collapse in on the car's occupants during a rollover would be more of a "good thing for safety" than one which did.

Mozilla Launches Persona Identity Bridge For Gmail

thelovebus Re:Identity Federation? (114 comments)

Persona/BrowserID is a lot closer to OpenID than SAML or OAuth.

Doing SAML federation can be a bit of a nightmare, and AFAIK there's no "standard" way to do sort of on-demand federation between two entities (that is, if user using IdP A wants to visit service X, usually A and X generally need to already know about each other).

OAuth really isn't about *authentication*. It can be used for authn as sort of a side-effect, but it's really not its' intent.

As for OpenID (and OAuth and SAML, too), the big advantage of Persona/BrowserID is that your IdP doesn't actually know what sites you're visiting. If you take the additional step of using unique email addresses to sign in to each different site you visit, there's also no way for two different sites to know you're the same user (at least, based on your BrowserID "identity"... obviously there's other tricks they can employ).

Eben Upton Muses on the Raspberry Pi, Scratch and, His Love For Parallela

thelovebus Boot into a REPL is the right path (71 comments)

When I first read about the Raspberry Pi I was excited because I thought they were going to recreate this boot to a BASIC interpreter-type of experience we used to have on Apple II's and TRS-80's and the like. That's the sort of experience that they claimed inspired the raspberry pi, and they claimed that sort of programming-based, learning-intensive experience was what they wanted the pi to be about.

So, I was very disappointed to see that by default, a raspberry pi really is "just a pc" that boots into your typical CLI, and the "getting started" instructions actually have the new user start up X right off the bat. Providing scratch and a python IDE are nice and all, but I feel like all the normal trappings of "just a pc" take focus away from the real point of the pi.

Industrious Dad Finds the Genetic Culprit To His Daughters Mysterious Disease

thelovebus Re:Phenotipyc variance (204 comments)

Agreed, but I think it's a hard issue to have a rational discussion about, without emotions outweighing reason. On the one hand, if society at large decides a genetic trait is undesirable, is it wrong to prevent people from screening for that trait? Heck, even if society decides a genetic trait is desirable, is it right to prevent people from screening out that trait for their own reasons? I know it's cliche or a platitude, but most of the time, determining right and wrong (to the extent that we could create effective rules or regulations) in these cases is really, really hard.

A Truckload of OAuth Issues That Would Make Any Author Quit

What are you talking about? The original submitter? Eran Hammer? The blog being linked to?

I honestly don't know what you're referring to -- could you explain for those of us who are out of the loop?

Ask Slashdot: Dealing With Flagged Channels For XBMC PVR?

thelovebus Re:Use the analog hole, Luke! (328 comments)

One potential objection to this is that you can't generally get most HD channels on a non-digital service tier. Probably for the very reason that they can charge you more for the same content by only providing on the digital tiers.

Planetary Resources To 'Claim' Asteroids With Beacons

thelovebus Will this be like patent trolling? (221 comments)

On the one hand, mineral claims have a long history and seem to have worked decently.

On the other hand, how do we prevent an unscrupulous company from doing just enough work to *claim* these asteroids, with no intention of actually following through and mining them. Then, acting as a rent-seeker when another company actually does try to mine the resources?

3D Printable Ammo Clip Skirts New Proposed Gun Laws

thelovebus What's more likely? (1862 comments)

That our esteemed legislators say to themselves
"Well, that's that, then! I guess it's pointless to ban high-capacity magazines."
or
"This is insidious! Alongside a high-capacity magazine ban, we should also ban 3D printing! Clearly it's a technology that will only be used by TERRORISTS!"

I think something like the latter is more likely, and I'm not even one of /.'s famed government-hating libertarian fundamentalists!

The plans & pricing page mentions that the $300 fee can be paid over the course of a year:
"$300 construction fee (one time or 12 monthly payments of $25) + taxes and fees". (from https://fiber.google.com/plans/residential/)

Political Science Prof Asks: Is Algebra Necessary?

thelovebus Re:yes (1010 comments)

"My cousin is dyslexic and has terrible trouble reading and doing mathematics, but he's sitting pretty on a pile of cash and he's great at his job."

Okay, I'll take your anecdote to the next level -- since your cousin is apparently rich, but dyslexic, obviously schools don't need to teach kids how to read, either. Anecdotes are fun!

Chinese Physicists Achieve Quantum Teleportation Over 60 Miles

Of course that means they have two identical people, so they have to kill the original.

Discussion of this sort of thing always reminds me of this great cartoon.

Quantum Experiment Shows Effect Before Cause

thelovebus Re:Reality versus Obeservation (465 comments)

Always thought it was a Feynman quote, but I can't find evidence of that now.

Maybe it's just like this experiment -- Feynman hasn't actually said it yet.

Quantum Experiment Shows Effect Before Cause

thelovebus Re:Maybe I'm Understanding This Wrong (465 comments)

I've only read the ars writeup, and not the paper itself, but here's the impression I get:

Using your stated setup, the apparent "violation of causality" from this experiment comes in that measurements showing that A & D are entangled happen *before* the entangling of B & C. So in a completely arbitrary sort of timeline-form:

0:00 - A & B are entangled. C & D are entangled.
0:01 - A is sent to Alice. D is sent to Bob. B & C are sent to Victor.
0:02 - Alice measures A. Bob measures D.
0:03 - Victor decides whether or not to entangle B & C.

In the cases where at 0:03 Victor decides to entangle B&C, the measurement taken at 0:02 shows A & D as entangled.
In the cases where at 0:03 Victor decides *not* to entangle B&C,the measurement taken at 0:02 doesn't seem to show A&D as entangled.

From this, we get the apparent break in causality, in that a measurement taken at 0:02 is apparently affected by something that doesn't happen until 0:03.

Does 'Supersizing' Supershrink Your Brain?

thelovebus Re:Yeah, yeah...everything enjoyable is bad for yo (283 comments)

I can't tell if you're being serious or not, especially with, " Even if it would turn out that people are too stupid in aggregate and would technically benefit from a despot or anything less that direct and absolute democracy."

At what point does "technically benefit" not equal better? I know this isn't exactly a single-factor situation, but since we're only talking about a single situation, when you say something is beneficial (or perhaps, *more* beneficial), that pretty much by definition means it's better.

And in my opinion, a 24-hour Athenian democracy like you seem to be advocating is great in the same world where communism is great or libertarianism is great : a utopia where every human is perfectly-informed and respectful of every other human. Maybe we'll get there one day, but we don't live in that world today.

Justice Dept. Files Antitrust Complaint Against AT&T and T-Mobile Merger

thelovebus Re:Sprint and T-Mo should merge (301 comments)

I'd argue that prior to the last few years where smart phones have become incredibly popular, Sprint tended to offer some of the best/most advanced phones available (other carriers did as well), so your argument that they offered "the worst phones" seems completely wrong to me.
