have a look at https://projecteuler.net/

for "Thinker" brain food. (it still has the issue of not being a pragmatic use of time, but there are plenty interesting enough questions which it at least helps)

That is actually not so bad a reason. I use build123d, but want it in haskell, enough to look at how hard it would be to create something similar.

(I also totally agree about the gui being worth having sometimes, and would have loved the ability to fully mix. Code as the main driver, but gui to help choose it. For example to figure out faces and other attachment stuff)

they do have satellites. I'm less sure about how much they care about them - but they are not cheap

That's my point. They have so few that sacrificing them would be irrelevant.

worth also looking at cadquery, build123d and similar

because even when it isn't why people come here, and if there was too much of it you may be right - a message which brings up a smile or warm feeling is enough for people to be thankfull

and that is a good thing

Obviously the article is voted to the top. So the the lurkers at /newest and the general HN audience must like this. Still I wish though that upvoters stuck to the HN guidelines of upvoting stuff that really gratifies one's intellectual curiosity, not just some feel-good piece. There is no shortage of other places where I can find feel-good articles. I want HN to stick to HN guidelines.

This is all the more sad for me because among all the spam, many high effort articles get posted to /newest but many don't get the upvotes. These shallow, feel-good articles always get the upvotes. I guess it takes more time to read and appreciate a high effort article. So I understand why this happens. But ...

have you also used thumbkey (or messagease) by any chance?

if so - can you compare them?

(I use thumbkey, but when I ran across 8vim considered switching

however I use thumbkey fluently and am not sure if worth switching)

i was pretty quick with thumbkey, it's nice on even a tiny device like a Jelly Star. nowhere near as quick with 8vim on any device yet.

will space-edition pokemon go be the only reason some people go to visit earth one day?

so matrix? (which has it's own issues, but will hopefully overcome them eventually)

not eink, but have a look at pinetime
