It seems like this gets easier as the kids get older; I've seen parents of teenagers make it work. For some folks it's a family affair---several kids & one or both parents learning to fly. These families have been uniformly super fun to have at the field! For others I think it's a matter of the kids being old enough to have some independence, + I'm sure a very supportive partner.
So don't give up on gliders forever! I'm expecting times in my life when I can't get out to the field enough to stay proficient & safe, and I'll have to quit flying for a little---but a dearly hope not forever. It's just that, likewise, now's maybe not the right time for you.
Very much the case! (Well, idk quite what gp imagined, but it's not as expensive as many things.)
When I was learning, around 2020, I budgeted ~$300 / month for glider flying, + ~$600 (I think: they've gone up!) for annual club dues. These days the monthly would be a bit higher, and the dues more like $700-800, I think. Flying as a club member is a lot cheaper than rides; you pay for the tow and for time on the aircraft, but aircraft time is way, way cheaper than power (no fuel to burn, no engine to maintain) and the instructors are volunteers.
NB this is in a club environment. The upside is that it's cheap and the club environment is a really good place to learn by osmosis / watching everybody else / listening to stories / seeing all kinds of different situations. The downside is that it's a huge time commitment. You'll drive 1.5 hrs and hang around all day to get twoish flights, sometimes < 10 min. each. And you have to be willing to commit all of every Saturday (or Sunday) for a year plus: you need to be flying just about every week, and given that some weekends'll be weathered out you have to be ready to take advantage of every flyable weekend. Folks that aren't committed just don't make progress: hang around, season after season, still flying with instructors, until they finally give up or just occasionally grind it out.
(I did the bulk of my training in 2020 and spring/early summer 2021. This was perfect: I was single and newish to the area I was living in, and thanks to Covid I had nothing else going on in my life. Even as things started to reopen in 2021 it was easy to maintain that "saturday? of course I'm at the field" habit.)
This is all harder to do as a Real Adult with responsibilities. Some folks manage to do it, but it's harder. Commercial operations, where you go and get a whole bunch of flying in relatively quickly, are also an option---but I hear there's a wide range of quality, and even the best won't get you the seasoning / airmanship you get from hanging around at the field every weekend for a year, flying in all sorts of conditions and taking advantage of the unofficial ground school from all the other instructor/student pairs there at the same time.
The economics change first once you've got your rating, when you're no longer doing short training flights and the bulk of your flying is (one hopes!) longer soaring flights; and then again when (if) you buy your own glider---but it's still that few thousand bucks / year order of magnitude. Expensive, but doable, especially compared to power.
Gliders themselves range from "surprisingly inexpensive" to "less expensive than a new powered aircraft", more or less. I'd expect to hear something like $5,000 for a Schweizer 1-26 (https://en.wikipedia.org/wiki/Schweizer_SGS_1-26: classic glider, still widely flown by a devoted community, but appreciably lower performance than gliders built after the massive jump that came with the switch to fiberglass); I have a part-share in a Jantar (https://en.wikipedia.org/wiki/SZD-41_Jantar_Standard, early fiberglass) that totals $25,000 or a little less, with reasonably nice avionics.
So, all told, yes, flying gliders costs a meaningful amount of money, but isn't terribly terribly expensive. The question to ask yourself is really not whether you've got the money, but whether you've got the time.
As for multiple choice and q&a---my practice is to make both Cloze and basic cards for, well, most things---Cloze are good for the early steps and for seeing how different pieces fit together, but basic cards are more demanding, and without them I don't quite feel like I've learned a thing.
(FWIW my primary use is physics & the mathematics behind it, not language learning.)

From his perspective, of course, using Runge-Kutta makes perfect sense. This is "Huh: I have this tool, and applying it to this problem wouldn't be too hard; would the tool work?", not "I should create a new tool."

IANAL, though; could someone who knows more explain what's going on? How will the procedure and requirements for obtaining a warrant for such "remote access" differ from those for searching, say, a house?
Edit: as I typed, slapshot posted some helpful explanation.

This is even more true when I'm working on my own: it requires a substantial amount of effort to make it through one 25 min. pomodoro period.
