"Labor rights veganism" isn't the goal. You seem to be suggesting that unless someone can achieve ethical perfection, there's no point in doing anything . I don't agree with that. You also seem to be applying black

This isn't about how much people are paid.

"Everyone else does it" is a red herring, even if Amazon weren't arguably sui generis. And this isn't about hate. I simply decline to participate in behavior that is unapologetically wrong.

I've cancelled any and all memberships, subscriptions, etc. with Amazon and anything they own, and I'm no longer ordering anything from them. It's completely unacceptable to treat workers this way, even if Bezos weren't

Reminds me of one my all-time favorite bits of movie dialog, which I keep in my mental back pocket as a sort of reminder: “Am I wrong? Am I wrong?” “You’re not wrong, Walter, you’re just an asshole. ”

Let's get the virus on the phone and explain that we don't wanna. I'm sure it will be understanding.

A similar model taught to pilots is DECIDE: - Detect that change has occurred - Estimate the need to counter or react to the change - Choose a desirable outcome - Identify actions to achieve the outcome - Do the necessary action

Can't tell you how many times I've had to reboot an autopilot.

Ground stop was just lifted but tower is still "ATC Zero."

Can confirm Midway tower is closed, although the airport itself remains open (albeit with a ground stop for incoming traffic). ATIS is broadcasting the following: Midway Airport Control Tower updates March 17 2227Z. Midway airspace has rev

My maternal grandmother (may she rest in peace) and I shared eerily similar night owl clocks. Left to our own devices, we'd go to sleep and wake up at exactly the same hour (roughly 3am-noon), whether we were in the same place or not.

Yeah, this is all marketing/partnership fluff. I'd be much more interested in seeing flame wars from Usenet. :) I was programming back then but I don't remember what the sentiment was at the time. I just remember Microsoft in

Oh, good question - not a rocket scientist but this history seems to say that’s the case: https://history.nasa.gov/SP-4206/ch7.htm ”Liquid hydrogen was only one half as dense as kerosene. This density ratio indicated

by danaliv 7y ago
The problem with hydrogen is that it has a lot of mass-specific energy but its density sucks. Jet-A has something like 35,000 MJ/m^3 while liquid hydrogen is a measly 8500.

I teach people how to fly. Trust me when I say that this is an extremely common misconception. It's one of the concepts students have the greatest difficulty wrapping their heads around.

I think the confusion here is stemming in part from the fact that "relative airspeed" isn't a well-defined term. In aviation airspeed means the speed of the airplane through the air (modulo specifiers for true vs. indicated v

> Air resistance goes up by the square of the velocity This is true of form drag. Airplanes are also subject to a somewhat counterintuitive induced drag that is inversely proportional to airspeed. The minimum total drag is therefore so

You can index the results of functions (or other expressions) in at least some databases. PostgreSQL can do this, for example. CREATE INDEX idx ON tbl (coalesce(col, '')) Combining this with UNIQUE can make for some neat tr

It’s not just about seeing you, it’s about seeing everyone around you too. ATC’s job is to separate aircraft and they can’t do that if they can’t see non-ADS-B aircraft. In fact just today I overheard an approach controller vector an Americ
292.
by danaliv 7y ago
Indeed. Not everyone even has to have ADS-B Out. You only need it if you’re going into or over Class C or B airspace, in the Class B veils, Class E above 10,000 except below 2500 AGL, and in Class E over the Gulf of Mexico. That leaves huge

Seven six, on the fritz! (Squawk 7600.) There’s an established, cut—and-dry procedure for when an IFR aircraft goes NORDO. Even without that handheld, you would’ve been fine. Every airplane between you and your destination, on the other han

Experimental aircraft need a special airworthiness certificate. You need an inspection by the FAA, and you have to do a flight test program before being allowed to fly it over populated areas.

That's because counselors, as a general rule, aren't routinely asked to build bridges. Engineers on the other hand do have to interact with other people, and more importantly, build things that affect people. Counselors also aren&

Neat. Sounds like I’ll be jumping down the rabbit hole to figure out why carbed cars vapor-lock but airplanes are the reverse. :)
297.
by danaliv 7y ago
Interesting. Fuel-injected aircraft engines get vapor lock—shutting down to refuel and then restarting can be a serious pain—but I don’t think I’ve ever heard of a carbureted one doing it.

Gear warnings are the “this website is insecure, are you sure” of aviation. They go off for all kinds of dumb reasons. You learn to tune it out whether you want to or not.

I haven’t played any of the others but I loved Far Cry: Primal. The Stone Age setting is (I think?) unique among video games. (I think there’s a Blood Dragon Easter egg in it too, incidentally.)

Nice to know I haven’t been imagining things! In 20 years of flying it’s really seemed to me like I’ve had way more high-surface-wind days (which I’ve arbitrarily defined as >20 kts) than when I started. It used to be a rarity and now it
