I’ve never seen IPA put anything but fats and greases into solution. I like IPA because it’s hardly a stronger solvent than water (do not estimate how strong a polar solvent especially distilled/demineralized water is!) and no risk of corrosion.

Submerge in IPA instead. It’s less likely to damage the watch further. Or just go outside and put on a respirator :)

(after you remove the pallet fork, that is, that’s the only part that can be damaged by IPA)

I have a decent Geiger counter these days (well, technically a dosimeter) for that. But in case of doubt, my recommendation is to submerge the dial in IPA, use Q-tips to wipe off the lume, flush IPA and double-wrap Q-tips before they dry then in the trash. It’s quick and safe that way and you probably want to relume anyway.

My absolutely not-fake Rolex has an acrylic crystal and it scratches up like there’s no tomorrow. Not a guarantee in general, therefore (dunno about this specific model, though)

You should see my Rolex 😂

If it’s acrylic, Polywatch will take care of that in a jiffy.

Is that 285 under the Omega sign on the movement? Calibre 285 from 1952 according to the serial number. That’s gonna be a heck of a restoration job :)

You’re probably not wrong, but there’s a difference between stumbling upon it in 2026 and pulling that off in 1958 :-)

Scheme has a chapter, after all it’s just Lisp. I think - I hope - that some pretty foundational stuff is treated throughout the book.

Yes you do! ;-)

Thanks! Clojure is a great example of a modern Lisp. Common Lisp is the Swiss army knife of programming and used everywhere you care to look, that is if you look hard ;)

While I won’t say that writing a text editor or rewriting (base) Emacs is easy, I think it is all about the ecosystem. There’s lots of Emacs reimplementations out there, some really good ones (like Lem), but they all have the same shortcoming: “no org mode”, “no magit”, and so on.

Emacs has a truly enormous ecosystem and only a reimplementation that runs everything unchanged has a chance of attracting enough attention. There was a time that that was seen as a worthwhile venture: Elisp was limited and slow. However, now with CL compatibilty and native compilation, I don’t see it happening. Not in the sense of something standing up that can and will actually replace Emacs.

Worse is better :-)

It’s just much easier to stop using them. Remember: its founder and largest shareholder (I guess) was one of the billionaire groupies standing behind Trumd during his inauguration. Canadians should not be shopping on Amazon.
