Is the Tesla Model S Pedal Placement A Safety Hazard?

And you don't have to floor the brake, any light pressure will overcome the idle speed.

That must be some awesome headlights.

French, Chinese Satellite Images May Show Malaysian Jet Debris

the_other_chewey Re:Great Headline (103 comments)

In my world geek news sources it's information - "The Chinese photo" would be shown or linked to. GPS coordinates would be accurate not "almost" a vague coordinate.

Jup. Pretty much all reporting on this is abysmal, from painfully simplified to just plain wrong and misleading.

One thing I haven't seen correct in any non-aviation specific publication:
The aircraft didn't send pings to the Inmarsat satellite, it replied
to pings by the Inmarsat satellite. It's an important detail:
That's why we know the roundtrip times.


One of best sources - maybe even the best source - is The Aviation Herald:
Malaysia B772 over Gulf of Thailand on Mar 8th 2014, aircraft missing, high degree of certainty: deliberate action

All images (including the new one) are there, all known technical information (times, positions, etc.) is there.
Updated information is highlighted with a light yellow background.

The most amazing thing: As far as I know, avherald.com is a one-man operation.

Oppo's New Phone Hits 538 PPI

the_other_chewey Re: approximately the resolution of an adult eye @ (217 comments)

For an adult human, 400-600 is about the limit of what we can detect.

No.

For most average human adults, the limit is about 300 dpi.

Speaking as a graphic designer with over two decades of experience, there is a reason that graphic designers have always targeted a print resolution of 300 dpi for colour images.

How 400-600 entered the conversation is beyond me.

Diagonals. Everything non-rectangular really. And that's just for monochrome.

Don't assume stuff that is valid for print to be valid for pixel displays. (also, there actually is print beyond 300 DPI...)
Print DPI (or LPI) are very different from display PPI: Print uses adaptive-sized, adaptive-positioned, overlapping, and even adaptive- shaped blobs of ink.

Displays use constant-size, fixed-position, non-overlapping squares (or rectangles) with discrete color-distribution
(no way to reorder subpixels: if a pixel is horizontal RGB, you can't make its right edge red. And making just its top
half yellow is even trickier. Print can do both.).

You need quite a bit more PPI than a good print's DPI to approach the same visual quality.

Firefox 29 Beta Arrives With UI Overhaul And CSS3 Variables

the_other_chewey Re:New UI? (256 comments)

Yeah with security holes and no updates I wont trust it.

What are you talking about?

The last SeaMonkey release, SeaMonkey 2.25, came out two days ago.
Its Gecko is identical to the one in Firefox 28.

WhatsApp: 2nd Biggest Tech Acquisition of All Time

the_other_chewey Re:My favorite observation... (257 comments)

List of things that would have been far more useful than a chat service[...]

Some 40 A380s at list prices (only chumps pay list prices for aircraft, so it'd be even more) [...] More than 26.000 flagship smartphones (Take your pick)

At over 730000 dollars per phone, those better come with a flagship attached.

Dead Reckoning For Your Car Eliminates GPS Dead Zones

the_other_chewey Re:My Toyota has had this since 2004... (151 comments)

cutting-edge GPS receivers can pull satellite signals out from all the way down to a few dB above the noise floor now, even in "urban canyon" locations where signal is blocked by buildings as well as being muddled.

I'd certainly hope so, considering that the satellite signal is considerably below the noise floor once it reaches the ground... (sources vary between 20dB to 26dB below the noise, I didn't do the math myself)

Graphene Conducts Electricity Ten Times Better Than Expected

the_other_chewey Re:I am in Beta Now, (161 comments)

When you're not on your own computer you have little choice of browsers. I, for one, would be furious if someone installed anything on my computer without permission and I refuse to do it to anyone else.

That's perfectly all right - I'm not blaming you. However, you should absolutely be
blaming your IT department, IE7 is incredibly deprecated.

CERN Wants a New Particle Collider Three Times Larger Than the LHC

the_other_chewey Re:Straight-line acceleration (238 comments)

Wouldn't the optimal path to increase the speed of matter as rapidly as possible be a straight line?

Yes. And it is being given serious thought.

It's only really sensible for a certain class of particles though, so it complements the LHC (or its successor),
but doesn't replace it. The main issue is that in a linear collider, one can't "reuse" the accelerating elements
by sending the particles through more than once. That is very limiting for heavier particles and makes the
ring more efficient.

Perhaps it's impractical, but they could conceivably build an accelerator that wrapped the surface of Earth.

That's wouldn't be a straight line anymore...

isn't one of them. IE7? Seriously? And you blame the website?

Does Anyone Make a Photo De-Duplicator For Linux? Something That Reads EXIF?

the_other_chewey fdupes (243 comments)

No need to roll your own. If the redundant files are identical (the
problem as stated lets me assume that), use fdupes.

"Searches the given path for duplicate files. Such files are found by
comparing file sizes and MD5 signatures, followed by a byte-by-byte
comparison.
"

It's fast, accurate, and generates a list of duplicate files to handle
yourself - or automatically deletes all except the first of duplicate
files found.

I've used it myself with tens of thousands of pictures to exactly do
what the OP wants.

NYT: NSA Put 100,000 Radio Pathway "Backdoors" In PCs

the_other_chewey Reading comprehension (324 comments)

I don't doubt the existence of physical bugs, but the claimed scale
of 100k devices in the field isn't supported by the article.

They infected 100k machines with software, most of them remotely.
(In that case, I consider the claimed number to be rather low even.)

It's right there in the first two paragraphs of TFA:

The National Security Agency has implanted software in nearly 100,000 computers around the world that allows the United States to conduct surveillance on those machines and can also create a digital highway for launching cyberattacks.

While most of the software is inserted by gaining access to computer networks, the N.S.A. has increasingly made use of a secret technology that enables it to enter and alter data in computers even if they are not connected to the Internet

The Hobbit and Game of Thrones Top Most Pirated Lists of 2013

the_other_chewey Re:Bullshit (193 comments)

I haven't figured out why they won't just sell you an HBO Go subscription as a separate entity. They have a digital content distribution system in place. It has support on many different devices. Yet they still require that you buy their channel through a cable/satellite provider and THEN get access to it.

Why not just have an HBO Go subscription for $10/month? They can cut out the middle man (cable companies) and get a lot more customers that only do internet based TV.

HBO doesn't want to cut out the middlemen, because doing so would actually lose
them money (or at least not make them as much as one would expect, while at the
same time seriously pissing off their current revenue sources):

Why Doesn't HBO Allow Non-Cable Subscribers To Subscribe To HBO Go à la Hulu?

Netflix: Non-'A' Players Unworthy of Jobs

the_other_chewey Re:'A' Players Make a Lot of Questionable Decision (397 comments)

I think the choice of VC-1 came because it was supported by Silverlight while H.264 was limited if present at all. VC-1 is also the protocol of choice for Blu-Ray, and the time saved simply copying the files instead of moving them to H.264 may be significant.

While VC-1 is part of the mandatory codecs in the BluRay standard due to very heavy lobbying by
Microsoft at the time, I've yet to encounter a single actual disc using it. There are some of them out
there (it is used a lot by Warner Brothers), but "of choice" VC-1 certainly isn't.

And copying files from BDs to directly use as streaming sources? With their double-digit megabit
per second encoding bitrates (the maximum video bitrate alone is 40MBit/s)? Absolutely not.

Big Buck Bunny In 4K, 60 Fps and 3D-stereo

the_other_chewey Re:What are they displaying this on? (102 comments)

Each stereo pair is shown twice, alternating between left and right.

Aren't the left/right frames projected at the same time?

The "shutter glasses" way of doing stereoscopic projection needs
temporal separation, otherwise the shutters would be useless.

But even with systems using (circular) polarisation, that would
require two completely independent projection paths, which basically means
two projectors. That would be much too expensive, so: No.

Big Buck Bunny In 4K, 60 Fps and 3D-stereo

the_other_chewey Re:What are they displaying this on? (102 comments)

Is this full 3D at 60fps, or is this the 4K equivalent of HRF3D like the Hobbit which will simply show 30fps to each eye alternating?

The Hobbit is 48 frames per second per eye, and is projected "double flashed":
Each stereo pair is shown twice, alternating between left and right.
So the projector is actually projecting 192 images per second.

Standard 24Hz stereoscopic content by the way is projected triple flashed, resulting
in 144 images per second.

Nice amount of in-depth detail here:

SpaceX successfully test nine-engine-cluster

the_other_chewey the_other_chewey writes  |  more than 5 years ago

the_other_chewey (1119125) writes "On their test facility in Texas,SpaceX, the privately funded space-flight company, have successfully tested their nine-engine-cluster which is planned to provide the heavy lifting capability for their Falcon 9 and Falcon 9 Heavy rockets.

The firing lasted three minutes (a full "mission duty cycle", i.e. a simulated launch) under full power, delivering 3.8MN (or 855,000 lbs.) of thrust. SpaceX have made a video of the test available. The Waco Tribune has a short report about it, with comments by locals."
