After 2022, it's both hilarious and sad to see how blockchain type recommendations have fallen off so hard.

What a gigantic waste of time and effort that field has been. I still have yet to see anything useful come out of it. NFTs always are pointed to as the "useful" thing, but tbh, if I'm buying art, I'd much rather have some well regarded painters work hung in my living room.

Not some monkey as my twitter avatar. Shrug.

My goal: build an outdoor robot to keep the deer away from my plants. Learning goals: - Brushless motor control: has now reached cheap commodity status and would be good to learn more about. In the past I was always stuck between DC toy motors and full 6 wire AC motor control. - Vision system on a small micro with edge-AI model for deer detection. After decades of classic machine vision I think it's time to overcome…

I love this goal, best of luck with it. I would like to build (or buy) a robot to protect my chickens from air and ground predators during the day so they can happily free range all day.

I think this is just the wrong way to go about learning things. There are 3 things to learn at any given time: 1. That which never changes i.e. humans, yourself and others 2. What you need to know to succeed right now i.e. deeper in your current tools and systems, or those you'll need to use next month 3. Whatever intrigues you. Maybe this is what you're asking: what's new to be intrigued by? To the latter, I would s…

For 1. specifically, I like this quote from Jeff Bezos: > I very frequently get the question: "What's going to change in the next 10 years?" And that is a very interesting question; it's a very common one. I almost never get the question: "What's not going to change in the next 10 years?" And I submit to you that that second question is actually the more important of the two -- because you can build a business strate…

Interesting, because I wish Amazon actually had better curation (aka less selection). There’s a lot of crap on there right now.

AI: and not just deep learning, ml, etc. I mean just using AI tools in a responsible way - I don't mean bypassing safeguards, I mean recognizing when you should fact check it. In a way, reliance on AI that is imperfect might actually increase people's 'fact checking' abilities because these are severely lacking in society right now.

E.g. Be able to use chatGPT to help you code, but not if you're maybe a junior and can't discern good code from crap. It should be basically a subordinate who you do code reviews with, not the other way around, though when it's on it's game if you don't understand a concept it can explain it pretty damn good. Again that's assuming it isn't making things up.

It would be nice if there were a toggle, or slider for: truthfulness, and reliability. Where basically it has little creativity to 'create' things that don't exist, unless reliability is set to 'creative' or 'low'. If I'm writing a fiction novel, that's what I want. If I'm coding it isn't.

I think AI consulting and workflow management will be big in the coming years. It's obvious so many things that we can do with this tech to us, but to many people they just don't 'get' it, and there's money in showing them.

This sounds like an amazing project and learning opportunity! Reminds me of a halfbaked hardware+software project idea of my own:

- Goal: increase the amount of natural light in my apartment during the day

- Mount a flat mirror on a motorized sun-tracking attachment on south-facing balcony railing

- Set up geometry, software, and motor to rotate the mirror so that it always reflects a beam of sunlight into the apartment, trained on a target area between the wall and ceiling, above eye level of occupants

I'm going to try and learn Rust (started and failed several times already), probably by building something with actix-web

My goal was to explore and learn Rust and/or Go in 2022... Not sure the remaining 2 weeks will cut it, so I'll have to carry the goal into 2023.

You can learn Go in 2 weeks. That's one of it's selling points!

Just dig into the official resources [1].

I feel ya, lost many chickens to raccoons, hawks and even a dog once.

Cool idea, there is a town in Austria where the sun doesn't shine in winter and they were going to build something like that on the adjacent mountaintop. I think it never happened, though.
