The speed of sound is NOT constant, but rather dependent on air density and temperature, and thus varies with altitude.

They do have what you originally meant, and only a little more expensive:

When Gizmodo switched over to this new comment system, I was so happy to see that Lifehacker had retained the older one. I see now that happiness was ill-deserved.

Given the production value of the little commercial, I can't imagine that they actually secured a license from Apple to use their precious dock connector.

I've done this, and it does serve a purpose...but it's not perfect.

And if you repeatedly post those updates and nobody likes them, will it let you know to knock it off?

With my current job in computer repair, I can't put enough support behind the tip to make recovery media. Most manufacturers provide easy-to-use programs to accomplish this, and will notify and nag you to actually use it. Sadly, most people still don't use them, and when you tell them you'll need recovery media,…

No one said he had to like it. And he can definitely complain about it...it just makes him look like an entitled brat.

No one's forcing them to shop at that site. If they want to shop there, it's their choice; if they want to use IE7, it's their choice; and if they see that they'd be taxed for it and proceed anyway, it's their choice.

Thank you, Lyle, you're quite right! "Hoosier" is sort of an all-encompassing term. The next closest one in meaning might be "white trash," but you don't have to be white to act like a hoosier, and I don't know the woman's race anyway.

Ugh...and this is the second-closest Wal-Mart to me. Stupid hoosiers...

Not exactly a steadicam shot, but I've always wanted to see a behind-the-scenes on that long uncut take from the first Kill Bill movie once she enters the club near the end. Now THAT was impressive!

MiGs seem to love doing this (and photographers, this angle).

Oh trust me, I know. My concentration within aerospace was CFD. Now, it's not like I did a full graduate study in it, just a couple classes beyond the normal aero stuff, but enough to give me an idea. I even had to write a simple 2D solver in MATLAB for it (which I actually found fun, but then I like doing weird…

In my aerospace classes, where they used crazy stuff like "slugs" for mass (among other oddities), it was pretty common to memorize conversion, do all the work in metric where it's easier, then just convert back to Imperial for the final answer. It may seem like a couple extra steps, but it made the middle part of…

Wow...so many people that didn't even bother to read all that was written and seem to believe the author is saying that these people want filters for everyone, when he very clearly states the opposite.

I like your nuclear facility photos. :P I'm aerospace here; if you dig through the individual sets, you'll find some nifty fluid dynamics photos.

I've never sold any of mine. :-( But I have had a few requests to use them in articles or other public display. Usually, I'm just happy that other people enjoy my photos and want to share them, I don't really care about making money off it.

That all depends on the cause of the meltdown. If it was a rookie mistake, then yeah, but if it's something not commonly known even among most electricians...that's another matter. Though, I can't immediately come up with a good analogy for this example of yours.

Thanks! Ha...it may be a bit mean, but when I saw the first page of yours, the first thing that popped into my head was "Instagramaholic!" :P It's fun to get a peek into other people's lives, though.
