Non Linear Dynamics course by Elisabeth Bradley: https://www.youtube.com/watch?v=MizhVorgywY

Started implementing some algs in Rust, just to learn it. Liz Bradley seems super impressive as a teacher and researcher, haven't heard easier explanations for complex concepts :) The course is mind blowing to me so far.

There's more on the https://www.complexityexplorer.org/ website.

Clojure. Is a complex language but it seems really speeding up your programming when you learn how to use it properly. And the community is really addicted to it.

Two things that accelerated my learning:

1. There are several fantastic books on Clojure. The Joy of Clojure and Elements of Clojure are some of my favorites.

2. Watching a professional using an editor/IDE with a REPL attached to it. Look for online videos. This is the biggest reason to why people are „addicted“ to it. The language and it’s ecosystem are made in a way that enables this „living in the code“ experience.

Does anyone have resources for learning Clojure?

I am interested in the actual Clojure bits. I mean, I know Lisp syntax and functional programming basics. But one also needs language-specific things: standard libraries, namespaces, etc. What is a nice resource for these?

Piano. I've decided that more programming languages or web stacks are a complete waste of time. Piano is for life and I wished I had started doing this in earnest long ago.

A fun tech-related project is hooking up an addressable LED strip to a digital piano and making the strip respond to your key presses - via a Raspberry Pi. My repository for this (code finished, just need to add photos and add a write up about how to use): https://github.com/whyboris/Digital-Piano-LED I added a feature that the left and middle pedal buttons navigate through sheet music (PDF left/right button). And I'…

Update: I coded-up a full-screen visualization to display on the screen. My setup has a 55" screen right above the piano, so there's great potential to make a pretty show.

Still WIP, but easy to edit: https://github.com/whyboris/Digital-Piano-Visualization

I used Processing because of how easy it is to use and how performant it is for smooth animations.

Learning Latin following this method: http://wcdrutgers.net/Latin.htm and also working on some mobile apps (iOS using SwiftUI, lot to learn but pretty pleasant experience) for personal use. Edit: In the past I've tried to do too many things at once and ended up making only limited progress on any of them as a result, so I'm trying to focus on just 1 or 2 things at a time now.

Thanks for sharing that link, I've been exploring options on the best way to learn Latin.

Complexity Economics I've been binging books on the topic as well as exchanging dialogs with a colleague over email. Books list: _Completed_ The Origin of Wealth: The Radical Remaking of Economics and What it Means for Business and Society - https://www.amazon.com/gp/product/1422121038/ref=ppx_yo_dt_b...

Any tips for getting started? Should I do lessons? How can I motivate myself to practice when I could just be browsing reddit?

To sleep on my back. Being a life-long side sleeper has caused a lot of shoulder and upper back problems that sometimes make it hard for me to reach out and type. I wish I'd done this ages ago. It's one of the hardest things I've had to learn.

I’d love to have a hole in my mattress and sleep face down with no pillow. It’s so comfortable but can’t find a way to breathe.

As a web developer, I'm often ashamed to admit that I knew very little about AI. Especially because I worked on a AI product on my day to day. I was perfectly fine debugging our python code and updating spacy, but had no clue what it was doing internally. So 6 months ago, I quit my job, published a short book, then studied AI. It's funny how so many material makes the vast assumption that you already know so much. Th…

What is this? Will it help you get a job?

I'm in Sicily for 40d, remote working and learning kitesurf and windsurf.

Kitesurf is really nice but you need to account for a few lessons before you can even stand on the board and prob a few more before you can rent on your own. In my case I did 6h base course, then another 10h with the teacher, typically 2h/day.

Windsurf you can start cruising around much faster, so I guess it's more rewarding immediately. This said many ppl told me that the progression is the opposite, meaning that with Kite you get better quickly, but with Wind it takes a lot of effort to grow from beginner.

On the language/stack side I'm deepening typescript and nestjs (nest with a S, not next) and will prob play more with rust soon.
