When I was a kid, I once brought a stethoscope with me on the airplane so that I could watch the movie for free. (Or rather listen to it.) I pulled off the heart-listening cup part of the stethoscope and inserted beverage straws into the rubber tubing. Then I put one straw into each of the two little holes in the armrest. It worked perfectly! Until a stewardess caught me and made me stop.

Loose or easily dislodged materials. My belt buckle was ok to keep on. Had to empty my pockets, take off my ring, metal piercings are disallowed.

You don’t want gobs of belongings piling up on your magnet, and you don’t want something large enough to pin the human between it and the magnet. The first scenario is quite expensive to rectify. The second is quite expensive, quite painful, probably fatal, and certainly traumatic.

I thought these were a nice idea when I had my MRI the other day, little did I know that I would barely be able to hear anything over the noise of the MRI machine. Ear plugs were better, kept out the noise of the MRI machine and let me drift into a trance.

I recently got an MRI and the technician asked me what I wanted to listen to on the headphones. I said "Something relaxing, do you have ambient music?". This turned out to be a terrible choice; the music was so quiet I could barely hear it. Earplugs would have been better. I had some in my pocket that I brought but it was too late. So after the claustrophobic panic subsided and I realized I was left in there with not…

That was a golden opportunity to experience ambient music in the most historically authentic way possible!

Listen to Brian Eno's story of what inspired his 1978 album, "Ambient 1: Music for Airports":

Yeah, on one armrest you had the sound-tube headphone "jack" and the other armrest had an ash tray. Wild times.

It was united that I most recently encountered this too. It was 2005ish and they flew a 747 with pull down theatre screens and pneumatic headphones on an australia-us flight. Not sure if that was the backup plane or they were just desperately holding out to upgrade the fleet. Having said that anyone that flew just over 30 years ago would have likely used pneumatic headphones and watched on a shared pulled down theatr…

Shared screens was the norm in Europe too, but pneumatic headphones is something I've never seen on a European carrier at all - not at all ruling out some might use them, after all, there are many of them and I've by no means flown them all. I wonder, though if it's another case of tech that may have been skipped by airlines that e.g. didn't add inflight entertainment as early as others and so got to "skip ahead" a g…

I haven't seen a inflight entertainment console in a few years of flying. There's a trend for some carriers in the US to remove them since most passengers would rather use their own tablet, phone, or laptop with much higher quality; and the carrier can sell them wifi.

There's a sci-fi book I read a while back that had as a plot point an alien species that had algorithmically optimized its decision-making processes so much that it was no longer recognizably conscious. I think about that now and again when I get a little too invested in some system or practice.

Was it good? Do you have the title?

It was! The whole book plays a lot with various types of consciousness. Although that was a bit of a spoiler, so out of respect I'll give a somewhat obfuscated link and just say if you're reading something by Alastair Reynolds right now you should consider that before following the link:

https://openlibrary.org/books/OL26809698M

(Reynolds' got enough books in his bibliography I don't feel like I'm spoiling anything by mentioning his name - I suspect I could come up with any random plot point and he's probably written it in somewhere)

Probably _Blindsight_ by Peter Watts

It was not, but that was also an absolutely fantastic book. I don't remember the sequel, Echopraxia, being as good, although there's a couple plot points from it that I do remember as weird ideas.

I've never heard this before! When I started flying it was just the 2 mono jacks that you still see on planes that haven't been updated (always wondered why it wasn't just a stereo jack) Pretty surprising to hear there's air/sound tubes rigged on to every seat on a plane. Seems like the sound tubes ended in the 70's: https://apex.aero/articles/sound-tube-surprising-history-air...

> (always wondered why it wasn't just a stereo jack)

Either because they didn’t want you to take their headphones from the plane, or so they could charge for use because you couldn’t just plug in your Walkman headphones.

Or both.

FILO is not the standard method of maintaining one's stock of clothes? How else does a person mange wear leveling?

My process: 1. Buy ~15 copies of everything. 2. Not think about what to wear! Everything is roughly the same. 3. Throw out everything every ~3 years. A couple of months before that, start buying new models of clothes to find the best one. 4. Goto 1.

> A couple of months before that, start buying new models of clothes to find the best one.

This is so important. You'd think that manufacturers would just keep the same stuff for sale all the time for all time but it doesn't work that way. Lands End comes close for button shirts and wool trousers, but that formality level is wasteful for work from home.

Edit: At first the 15 copies seemed excessive since only 7 are needed for weekly laundry, but basically you can get 2x longevity out of the stock based on laundry wear.
