440 N95s for $27 from Amazon. Is it a scam?
440 N95s for $27 from Amazon. Is it a scam? YouTube video by Gerard Hughes

Here's the YouTube video for context: www.youtube.com/watch?v=hgAK... (and Reddit thread too: www.reddit.com/r/Masks4All/...)

It's never a bad idea to check when you can! But for whatever reason, 3M only uses Safe Guard for certain products, and the 9205+ isn't one that you can check.

(If you go to the validation page on the link you shared, they note that it's only for the 8210, 8210CN, 9210+, and 9211+.)

(I guess I'm just intimidated hearing about very fiddly Linux distros and I'm worried it'll be like xkcd.com/1319 w.r.t. no longer having time for the original task :P -- maybe I will just try Ubuntu since it's hopefully more straightforward, at least as a starting point.)

(I'd like to be able to explore and mess with things, but at the same time, I think I'd want something stable and reliable enough that when I want to do other stuff, I don't have to fiddle / engage in yak shaving / go on side quests just to get back to the thing I originally wanted to do.)

By distros being fiddly, do we mean "I can fiddle when I want to", or does it end up being "an update broke something / I found something that's incompatible / now I *need* to fiddle to get things working again"? (Or is the latter usually a result of the former having happened? :P)

Is there a distro you'd suggest for someone who's fairly adept at poking at computers, but doesn't *want* to have to poke at computers too much? (Or is the best answer "go distro hopping and try stuff"?)

(Asking as someone who hasn't used Linux as a daily driver, but is maaaybe curious about it.)

I don't know why it started, but they've been naming their graphics card microarchitectures after people for quite a while: en.wikipedia.org/wiki/List_of...

Also, about the music: it's pretty niche, but if you're interested, there are hobbyists/fans who collect music loops from the parks! Here are a couple YouTube channels that usually have fairly accurate recordings or reconstructions:

Have you watched The Imagineering Story? It's a documentary series about the history of the Disney parks.

I think the craft that goes into themed entertainment and making immersive environments is really interesting -- if you feel similarly, I'd definitely recommend watching it!

Even though I can't see any aurora here, I love nights like these! Everyone always has such amazing pictures!

Looks like it was another small earthquake! USGS currently shows M 3.0 - 3 km SE of Berkeley, CA (2025-09-22 18:21:57 (UTC-07:00)): earthquake.usgs.gov/earthquakes/...

USGS website isn't loading currently, but ShakeAlert shows an estimated magnitude 4.5. Maybe a V (or even VI) on the the Modified Mercalli Intensity Scale?

Yep! USGS website is showing a 504 Gateway Time-out error for me currently though.

There's similar things in hospitals, right? Like those computer workstations on wheels? (I assume those are probably special and expensive though.)

Oh gosh, it's nowhere near as polished (and I had a friend help for the background art), but this is a clip of when I was testing it!

It's really more of a little code doodle than anything -- I just ported an RK4 integrator that I already had from a university problem set from Python to C#.

Ooh that looks so fancy! It's much cooler than what I experimented with when I first tried Unity!

I stayed up way too late watching the most recent episode of Star Trek: Strange New Worlds ("A Space Adventure Hour"), but the only thing I regret is not watching it sooner! It was such a delightful episode!

I guess it came full circle with the episode of Voyager where the ship got taken over and the crew was forced into holodecks to involuntarily LARP as members of the French Resistance. :P

I saw that sign last month! I think one of the questions the sign poses (well... posed) was quite relevant: "What do omissions in the historic narrative reveal about our society?"

Shout out to my local library for having database access!

(I had also found some other sources on random blogs and websites, but not all of them had references -- and on the ones that did, I wasn't able to directly track those references down, so I wasn't certain how authoritative they were. ๐Ÿ˜…)

Thanks for sharing that story in the first place! I hadn't heard it before and it was delightful learning a bit more aviation history. :)

"Hesitant at first, Mr. Wright smiled happily as he settled in his seat and soon gave the appearance of being perfectly at ease. Throughout the flight he gazed raptly at the earth, calling attention several times to various landmarks he once viewed from his own flying machine.

"Colonel Hatcher suggested that Mr. Wright take the controls, but the inventor shook his head. Hatcher again motioned toward the dual controls in front of Mr. Wright.

"Hesitantly, Mr. Wright placed his hands on the control column. Getting the feel of the plane, he shrugged his shoulders and beamed at Hatcher. The plane flew along at an even keel and a moment later Mr. Wright relinquished the controls.

"Later General Carroll ... took control of the ship. While Hatcher left the pilot's position so that General Carroll could slide into his seat, Mr. Wright again handled the controls."

When interviewed after the flight, Mr. Wright was beaming. Miss Stevenson quotes him: "It's absolutely marvelous," he said of the plane.

"You can say that I ran the whole thing. Put exclamation points and question marks after that---because all I had to do was just let it take care of itself."

He admitted that 40 years ago at Kitty Hawk, N. C., he never dreamed his invention would assume such proportions. He seemed impressed but not awed, as if long before this he had learned to take remarkable aerial development in his stride.
 
"Each one that comes along is a little better than the one before," he commented.

Starrett also quoted Wright as saying: "I enjoyed every minute. I guess I ran the whole plane for a minute, but I let the machine take care of itself. I always said airplanes would fly themselves if you left them alone."

According to www.jstor.org/stable/44524..., Orville is quoted as saying "I enjoyed every minute. I guess I ran the whole plane for a minute, but I let the machine take care of itself. I always said airplanes would fly themselves if you left them alone."

The text at the bottom is certainly, uh... telling of the current state of affairs.
