bewaretheirs··on Infinitone Microtonal Saxophone
There have been a couple types of slide saxes made but for whatever reason they haven't really caught on..

This one has keys that are actuated by the slide: https://www.youtube.com/watch?v=NJU9Rm-KviI (The last third of the video has a narrative in French describing the instrument, photobombed by a set of four serpents hanging on the wall behind the speaker. A serpent is a instrument that is sort of the opposite of a slide sax: it combines a brass-style mouthpiece with woodwind-like fingerholes).

This one looks mechanically simpler but it's not conical bore like a real saxophone: https://www.youtube.com/watch?v=vjnrM3GZMS8

I think that's standard eye/ear protection.

It would look really bad to lose someone after landing on the carrier.

The flight deck of an aircraft carrier is a loud, confusing, and dangerous place. I imagine they were told something like "this is not a time or place for sightseeing. hang on to the person in front of you and they'll lead you to a safe place below decks".

bewaretheirs··on Högertrafikomläggningen
> I have actually yet to hear a good "swede joke" at all actually; maybe they are just a myth?

Perhaps most of the good Swede jokes moved to Minnesota?

(seriously, a bunch of the intra-scandinavian humor seems to be of Scandahoovian-American origin. Like the "10,000 Swedes chased through the weeds / by one Norwegian" thing.)

bewaretheirs··on Big data is dead (2023)
You can go further.

There are relatively cheap adapter boards which let you stick 4 M.2 drives in a single PCIe x16 slot; you can usually configure a x16 slot to be bifurcated (quadfurcated) as 4 x (x4).

To pick a motherboard at quasi-random:

Tyan HX S8050. Two M.2 on the motherboard.

20 M.2 drives in quadfurcated adapter cards in the 5 PCIe x16 slots

And you can connect another 6 NVMe x4 devices to the MCIO ports.

You might also be able to hook up another 2 to the SFF-8643 connectors.

This gives you a grand total of 28-30 x4 NVME devices on one not particularly exotic motherboard, using most of the 128 regular PCIe lanes available from the CPU socket.

bewaretheirs··on Reclaiming IPv4 Class E's 240.0.0.0/4
The same way that 240/4 can become internet routable: a global effort to change defaults and push code and configuration changes everywhere over the next two decades.

It isn't all in use on most machines. Many hosts only use 127.0.0.1/32 and do not use the rest of the space; changing the default netmask on the loopback interface from /8 to something like /24 would be one step of the transition.

Like 240/8 it's probably not worth the effort.

bewaretheirs··on DNS glitch that threatened Internet stability fixed; cause remains unclear
What's your evidence that this is related to c.root-servers.net serving a stale version of the root zone?

If you can get the correct IP address for a site out of the DNS but can't reach the site, it's not a DNS problem, and not a problem with the root DNS servers. This is likely correlated only in time with the c.root-servers.net issue.

That said, your difficulty reaching indilib.org may be related to the Cogent-TATA peering dispute or one of Cogent's other peering disputes - from where I sit, a traceroute to indilib.org goes through cogent's network. But that's not what this submission is about.

bewaretheirs··on DNS glitch that threatened Internet stability fixed; cause remains unclear
Per rfc8806, because the data in the root zone has long TTL values, most queries to the root servers are for nonexistent top-level domains due to typos and search paths gone wrong, so in some sense it's community service to reduce useless traffic to the roots -- you do a single burst download of about 2MB daily instead of all of your query traffic.

Other reasons why you might do it are covered in rfc8806 - slightly reduced latency on cold-cache DNS queries, added resilience against DoS attacks against root DNS servers.

bewaretheirs··on DNS glitch that threatened Internet stability fixed; cause remains unclear
Note that running your own mirror of the root on the recursive nameserver(s) on your network will keep the traffic generated from these sorts of queries off the rest of the internet.

If you're already running your own recursive resolver on reasonably up-to-date software it can be surprisingly easy to set this up; see rfc8806 for some config examples.

bewaretheirs··on DNS glitch that threatened Internet stability fixed; cause remains unclear
The problem was evident if you ran

dig @${server} . soa

c.root-servers.net showed an older serial number than all the others yesterday.

This seems like a major hole in their monitoring systems.

bewaretheirs··on DNS glitch that threatened Internet stability fixed; cause remains unclear
Cogent's statement on c.root-servers.org:

"2024‑05‑23 - On May 21 at 15:30 UTC the c-root team at Cogent Communications was informed that the root zone as served by c-root had ceased to track changes from the root zone publication server after May 18. Analysis showed this to have been caused by an unrelated routing policy change whose side effect was to silence the relevant monitoring systems. No production DNS queries went unanswered by c-root as a result of this outage, and the only impact was on root zone freshness. Root zone freshness as served by c-root was fully restored on May 22 at 16:00 UTC."

Edit to add:

This was mentioned on Tuesday on the dns-operations list:

bewaretheirs··on Romance author gets locked out of Google Docs for "inappropriate" content
Google does a lot of things in a lot of different contexts. It's not always acting as a publisher but here I think it is, and it has claimed to be one in the past.

In 2012, Eugene Volokh argued on behalf of Google that it was indeed a publisher:

bewaretheirs··on Sonos App Redesign AMA
Half an hour in, and they have yet to answer a single question.
bewaretheirs··on Sonos App Redesign AMA
Sonos recently allowed a major app redesign to escape into mobile app stores before it was functionally complete, replacing a perhaps dated but definitely functional app that many people depended on.

They're now hosting an "AMA" on their product forums and it's going about as well as one might expect.

bewaretheirs··on Unix and Multics (2019)
Indeed. Porting it to an architecture that wasn't 36 bits wide would be a major undertaking. From my minimal reading of the source, PL/1 (or, perhaps, the dialect of it which was used on Multics?) lacks a real equivalent to C's typedef, and as a result you have explicitly sized types like "fixed bin(35)" and "bit(18)" and the like all over the place in the source.
bewaretheirs··on Unix and Multics (2019)
Ironically, one of the perhaps better known Multics stories involves a panic-style message from early in its boot loader.

It was in Latin. "HODIE NATUS EST RADICI FRATER".

bewaretheirs··on “Meta spent almost as much as the Manhattan Project on GPUs in today's dollars”
We're not talking about programming errors, but malfunctions in the hardware producing incorrect results - whatever the electromechanical equivalent of a bitflip is.

Given the error rates described by Feynman, if they had to restart the entire computation from scratch after a single detected error they'd likely never have completed the task.

bewaretheirs··on “Meta spent almost as much as the Manhattan Project on GPUs in today's dollars”
They used the best 1940's equivalent: IBM card tabulators. This is discussed at some length in Surely You're Joking, Mr. Feynman.

My favorite part:

"When I went back to work on the calculation program, I found it in a mess: There were white cards, there were blue cards, there were yellow cards, and I started to say, "You're not supposed to do more than one problem --­­ only one problem!" They said, "Get out, get out, get out. Wait ­­-- and we'll explain everything."

"So I waited, and what happened was this. As the cards went through, sometimes the machine made a mistake, or they put a wrong number in. What we used to have to do when that happened was to go back and do it over again. But they noticed that a mistake made at some point in one cycle only affects the nearby numbers, the next cycle affects the nearby numbers, and so on. It works its way through the pack of cards. If you have fifty cards and you make a mistake at card number thirty­-nine, it affects thirty-­seven, thirty-­eight, and thirty-­nine. The next, card thirty-­six, thirty­-seven, thirty-­eight, thirty­-nine, and forty. The next time it spreads like a disease.

"So they found an error back a way, and they got an idea. They would only compute a small deck of ten cards around the error. And because ten cards could be put through the machine faster than the deck of fifty cards, they would go rapidly through with this other deck while they continued with the fifty cards with the disease spreading. But the other thing was computing faster, and they would seal it all up and correct it. Very clever. That was the way those guys worked to get speed. There was no other way. If they had to stop to try to fix it, we'd have lost time. We couldn't have got it. That was what they were doing. Of course, you know what happened while they were doing that. They found an error in the blue deck. And so they had a yellow deck with a little fewer cards; it was going around faster than the blue deck. Just when they are going crazy ­­ because after they get this straightened out, they have to fix the white deck ­­ the boss comes walking in. "Leave us alone," they say. I left them alone and everything came out. We solved the problem in time and that's the way it was."

bewaretheirs··on North Yorkshire Council to phase out apostrophe use on street signs
If it sanitizes anything, parameterization sanitizes the code, not the data, and has much lower impact on the outside world (because the rest of the world isn't pressured to rename things in the real world to fit arbitrary constraints in the computer).

bewaretheirs··on Drone footage of fledging penguins jumping off cliff
Years ago I heard a possibly apocryphal story -- that's at least halfway consistent with what's seen in this video -- about how a mass of penguins decide if they're in a safe place to go for a swim:

They gather near the edge of the ice and jostle each other until one bird falls in. Then they watch to see if it gets eaten by a predator. If not, the rest of them dive in and go for a swim...

bewaretheirs··on NASA Veteran's Propellantless Propulsion Drive That Physics Says Shouldn't Work
Cars (whether powered by electricity, gasoline, or whatever) push against the road, and the amount of force (and thus energy) required as speed relative to the road increases.

But in space, we don't have roads. Rockets push against their reaction mass.

What is a hypothetical drive with no reaction mass pushing on?
