As a second regards the microwave, depending on the age, please be extremely careful about the magnetron the insulators on which could contain beryllium oxide, which can kill you.
There are a lot of fun parts inside microwaves (a personal favorite is the high-torque-low-speed-line-voltage motor, which I use to make creepy Halloween decorations) but the caps, transformer, and magnetron are all useful for somewhat... more dangerous... pursuits.
the insulators on which could contain beryllium oxide
As far as I can tell, this is an urban legend. No consumer microwave oven has ever used beryllium in its magnetron insulators. Military radar ones, yes (and likely where the legend started.) Some specialist test equipment and RF transmitters too, and they all contain prominent warnings of it. Besides its toxicity, it's far more expensive than regular alumina.
That's my understanding as well, but I still wouldn't disassemble a 1960s microwave without protection (I have assisted in the dismantling of a couple microwave communications devices which did contain BeO and were also very well-labeled as such). Anything from the 80s on at least is almost certainly aluminum.
There are approaches to real-time ethernet (some industry implementations like profinet or ethercat, 802.1as from IEEE) but support is spotty and it requires specialized gear to be effective.
(I'd gotten a large LG monitor instead of a flatscreen tv, and it didn't talk HDMI-CEC but it had a serial-over-TRRS control interface, so I listened for messages on the bus and my media PC translated and relayed them to the monitor.)
Does the Internet Archive provide any instruction to uploaders and users about how to go about uploading and downloading copyright-expired public domain works legally, given the geographical differences from region to region on copyright expiration? For example, does the Internet Archive host its servers in USA, and would that make the US copyright expiry law operative? Or does it have servers in Europe or Asia (more lenient copyright expiration laws) that can be intentionally uploaded to, and leaving it to users to download from their respective regional locations on their own cognizances (i.e. at their own risk)?
If you have the opportunity, I would strongly recommend visiting the vintageTEK Museum whose site this is on (it's just outside Portland) sometime. Many of the folks working there are retired from Tektronix themselves and the amount of (working!) equipment they have is astounding.
Yes! I went there on my first trip to Portland last year for work.
It was mesmerizing to look at all the beautiful equipment and meet all the cool people there. I've forgotten his name, but I spent at least one hour with an ex-Tektronix employee who started his career with tubes and ended it with writing FPGA code who told me many wonderous stories from his career. Highly recommended if you're at all into electronics!
Among the many reasons that stretch of 26 is dangerous is that the approach from Portland is essentially a freeway from Gresham through Sandy, and then turns into a rural highway until it begins the climb up to Hood. This is because of a remnant of the Mount Hood Freeway construction, which resulted in a lot of little oddities that linger in Portland to this day: https://en.wikipedia.org/wiki/Mount_Hood_Freeway
I'm maybe too close to the problem to evaluate well (studied foundational math) but I know that Lawvere and Schanuel's book "Conceptual Mathematics" has been fairly well-regarded as a path into category theory.
I had the same concerns awhile back and ending up running a slightly modified version of https://github.com/wiedehopf/mlat-client -- not quite as simple as an http push, but much simpler than a containerized feed client.
Do you happen to recall which version? I've picked up a couple kid's books/playsets but mine is ready for a chapter-book type version soon. FWIW my favorite reading copy is the UC Press version based on the incredible Arion version (https://www.ucpress.edu/books/moby-dick-or-the-whale/paper) but any edition based on the Northwestern-Newberry text is solid.
Sure, the kids classic version that I got is edited by Margaret Novak and published by Applesauce Press. It is actually chapter based which is nice, and it also has kid-friendly illustrations.
