I was a physics and mathematics double major in college and I got my Ph.D. in physics studying galactic cosmic ray electrons. I love brewing beer and watching rugby.

For #TuneTuesday and #EnterNight here is #Versengold live with Schlaflied.

Im Schlafe ist die Welt bei Nacht von aller aller Last befreit,
So schließ die Augen Kind, schlaf ein.
Schon Morgen wenn die Sonne lacht wird manche, manche Kleinigkeit,
Vielleicht ein Grund zur Sorge sein.

@dangillmor@mastodon.social Remember when Jayson Blair got dragged over the coals and fired for making up interviews and quotes? I think we're quickly sliding down that path with LLMs, but it will now be acceptable, or at least non-fire-able, because they are all using LLMs to write stories now.

@ambientspace@cloudisland.nz @kkremitzki@mastodon.social @nyrath@spacey.space It seems pinks and yellows were popular to use when shooting in black and white to get the desired grey tones: https://www.reddit.com/r/VintageTV/comments/1mv10yz/here_are_two_pictures_of_the_addams_family_main/#lightbox

@mattblaze The pictures aren't very great, but I found this web page (including a picture of the facility that was used on the cover of the local phone book!): https://w3.the-kgb.com/dante/military/milpics7.html

@DavidNapoli I assume you want to stop Johnson Rensselaer from doing something? 😀

@johncarlosbaez @dpiponi I made it very far in and around mathematics without seeing (or at least remembering or appreciating) that Euler sum to get -1/12. Then I saw everyone losing their minds when Joe Polchinski's String Theory book came out and it just stated it as a fact and continued on. My guess is that book was what spurred the creation of the many oft-cited YouTube videos that followed.

@res260 @huitema @dangoodin Privacy and safety are the entire reason I use blockers. Block trackers with something like PrivacyBadger and you'll see that it isn't about serving ads, but collecting your personal information and tracking you across all of your devices. I'd have a tiny bit of respect for them if they would just own up and say something like "If you want to access our site, you need to let us collect your personal information and sell your data."

@FediFollows@social.growyourown.services I can't get any of the German sites hosted on openbiblio.social to work. Perhaps their server is down?

@johncarlosbaez My comment was partly tongue-in-cheek, but I did actually check the link. My dissertation was about galactic cosmic ray electrons. It was written in the mid-nineties and I'm pretty certain it doesn't exist in any digital format I generated, which would have been PostScript. I vaguely recall having to provide proof-ready paper copies that were sent off to a company (UMI Microform) to be converted to microfiche. I can find it online, however. There is a company, ProQuest, that has a digital copy posted online that was made from scanning the UMI microfiche. It's a direct scan, so it not only has my copyright on the title page, but it also has a copyright statement from UMI saying "this version was created with permission of the copyright holder."

@mttaggart@infosec.exchange But real wisdom is only achieved when one opens themselves to the possibility that they themself may be the internet idiot.
