I'm recently passionate about motivation. I'm on the lookout for ways to keep me motivated. I always thought burnout is not my problem, until it hit me and now I'm looking for cure.

There have been a number of discussions on HN about this, with some interesting comments. Maybe:

I recently bought myself a copy of Ashley's Book of Knots, and been teaching myself... well... knotting. In my ignorance, I used to see knowledge of knots as this complex, hard to learn thing, but one thing I've been learning is that the more common, practical, knots tend to be fairly easy to tie. There's just different knots for different purposes. The decorative ones can get very complex, though.

What is your approach to learning them? Do you do them in order from ABOK or pick ones that look interesting and/or useful?

What are your favorite knots?

I've tried to learn a number of knots. I find that tying knots is a good way to keep my hands busy while doing something else, like listening in a meeting.

I favor the diamond knot, constrictor knot, hangman's knot, alpine butterfly loop, and Japanese square knot.

I’ve been reading up on diy speakers, with the eventual goal to make an excellent sounding pair myself. Ever heard a pair of speakers that didn’t sound like hearing a recording of an instrument, but rather hearing the instrument itself ? Me neither, but it’s apparently possible. The DIY speaker/audio hobby is highly specific but also fortunately has a lot of informative available online. I’d recommend diyaudio.com an…

> Ever heard a pair of speakers that didn’t sound like hearing a recording of an instrument, but rather hearing the instrument itself? Yeah, full-range drivers + tube amp. I built the tube amp and speakers so it was not really expensive at all. (Maybe $500 or so all told — so not audiophile expensive by any means.)

That sounds very interesting, which drivers did you use?

Also your website's pretty nice and the moongame seems very interesting but its performance in firefox is around 2fps, which is bizarrely slow (Safari on my iPad was smooth).

when you make them, be sure to post here about what you find out. It feels to me like that community does a lot of Q&A, but not a lot of build logs (Maybe I'm looking in the wrong places?) Also, if near Boulder, CO, I've got some CNCs if that helps you build stuff.

Thanks, that's very kind of you but unfortunately I live in the Netherlands haha. I'll almost certainly post my speakers when I make them, though probably on diyaudio or reddit.

Re build logs, I have seen quite a few on diyaudio.com as well as reddit's r/diyaudio and r/diysound (which I frequent much more often). Are you more curious/interested in the enclosure hardware (woodworking) side or the driver selection and crossover building side? Because if you're curious about learning to make crossovers there are a few threads specific to that on diyaudio.com.

There is a new show on HBO called Scavengers Reign, and it's become my favorite scifi story ever. https://www.imdb.com/title/tt21056886/ It's kinda like watching Planet Earth about another ecosystem, with a strong focus on judgment-free ecology (ie there isn't good and evil, just different flora and fauna and otherwise interacting both with their normal food webs and with human outsiders). It really tickles the envir…

Is this based on any of Jean Giraud/Moebius's work?

I don't know who that is (had to look him up), but some critics think the series was inspired by his look & feel:

I'm gonna start myself with something I got into again recently. I got back into game development as a hobby a couple of weeks ago (sadly just after Ludum Dare ended) and have since been learning Godot to make the switch away from Unity permanently. So far its ease of use has been a real game changer for me, although I miss having my IDE on a different screen. The goal is to know Godot well enough to take part in the…

A relative of mine teaches (free and paid) online courses for Godot: https://www.google.com/search?hl=eo&gbv=1&q=heartbeast+%2Bsi... https://www.youtube.com/channel/UCrHQNOyU1q6BFEfkNq2CYMA

Oh nice, didn't realize HeartBeast switched to Godot. When I first got into game dev with GameMaker Studio about 8 years ago I used to watch his videos a lot to learn, I guess now I'm gonna repeat that cycle for a different engine. Thanks for reminding me :)

I first just went through it front to back, having a go at some of the simpler ones as I went. Since then, I've mostly just picked ones that felt interesting to learn. I've been a bit partial to more decorative stuff lately: a few of the sinnets, Full Matthew Walker, Turks-Heads, that sort of thing.

I'd say my favourite one is one I come up with based on a Sheepshank, but (to the surprise of no one) was in the book as #1148 (Bell Ringer with two hitches). My use case, however, is as a double-noose to carry bags. Once tied, you can tighten one loop by loosening the second, then tighten the second by pulling the standing part. I tighten these around the neck of the two bags beneath the knots, then use a Marlingspike Hitch in the standard part with a piece of wood as a handle.

The following open research problem. Given an undirected graph G with two vertices s and t, the task is to determine whether there is an undirected path connecting s and t which is simple (no repeated vertices) and has length divisible by 3.

It is not known whether this problem is NP-hard, or whether it can be solved in polynomial time; apparently the question is open since the early 90s.

(The problem is also open for paths of length p mod q for any fixed p and q (fixed means they are constants, and are not given as input), whenever q>2. The problem is known to be in PTIME for 0 mod 2 and 1 mod 2, and to be NP-hard when the graph is directed. Pointers to related work here: https://gitlab.com/a3nm/modpath)

Mental health. I recently passed out in public and had to finally admit to myself that I’m severely burnt out. I had ignored the signs and mentally written off the concept of burnout as a bit of a wishy-washy mostly “emotional” concept and not as the very real psychological AND physiological condition that doesn’t just go away if you get a good nights sleep and a day off. It was emotional to actually read up on it an…

You are not alone! I have been dealing with burnout since the pandemic began. For me it was the inability to focus on the simplest tasks that made me realize I could no longer ignore the problem. Therapy has helped a lot.
