Is there a cliff’s notes? I tried to reach it via invidious:

Could not even get the transcript, and 403 forbidden when just trying to get audio.

pcregrep is not automatically installed with Debian but it’s in the official repos. It seems common to get:

pcregrep: Too many errors - abandoned.
pcregrep: Error -8, -21 or -27 means that a resource limit was exceeded.
pcregrep: Check your regex for nested unlimited loops.

But it will help in many cases. I can see that it works on sufficiently small files. I noticed the built-in grep function for emacs can be modified to use pcregrep w/-M added instead of grep, which I find quite important because emacs makes it very easy to jump around to visit different results. In the end it’s still a hack.

I currently use the find-grep function in emacs, which is basically: find . -type f -exec grep ‘my.*search.*pattern’ {} +

To do PDFs, I use something like find . -type f -iname \*pdf -exec pdfgrep ‘my.*search.*pattern’ {} +

My problem is generally when TOKEN1<space>TOKEN2 has a line break between tokens. It’s fucking annoying that grep is line-by-line. I wonder if Hister solves that problem. But from the website, I see no advanced syntax. I would love to search a pattern like word1 w/s word2, which would find cases where word1 and word2 appear in the same sentence. And word1 w/p word2 to match cases where two words are in the same paragraph.

I saw a video at some point on how to build an ultrasonic by epoxying an u/s generator to the bottom of a metal tub. Many adhesives fail when a surface gets sufficiently hot. I haven’t opened it up yet but I imagine they used some kind of adhesive, as opposed to welding it. It would be interesting to know if your cleaner uses glue or welding to fasten the u/s generator.

No, in fact the cheap thing is allergic to heat. The manual says it’s important to fill with /cold/ water. And the running time is restricted to like 4 min. If I run two cycles, the water gets a little warm despite (apparently) having no heating element. The manual also says not to run more than 2 cycles. So it seems the thing is sensitive to heat and the water functions to keep the ultrasonic generator cool, which makes it a bit sucky. I know pro jewelers who have industrial cleaners that have heating elements to deliberately make the liquid very hot.
