Hi Tildes,

I'm looking to introduce my children (aged 10 or so) to simple electronics (blinking lights, simple sensors, ...). I've played with Arduino in the past, but I see that there are now many competing options: Arduino, cheap rip-offs, RPi zero, adafruit, ESP32, ... It's easy to get lost!

Which do you recommend? Ideally, I'd like something cross-platform and open-source, easy to set up (ideally a kit with everything included), and of course not insanely expensive.

Edit: thanks everyone for the good advice! There are so many good options...

The English word 'crane' means a large bird or a giant lever-thing for moving heavy stuff. The Hungarian word 'daru' means both of the same things.

English and Hungarian are about as unrelated as languages get ... and yet, I keep bumping into parallels like that.

Thoughts, anyone?

I recently bought a keyboard and am going to dedicate 30 minutes a day to practicing piano. My goal is to be able to play my favorite songs (jazz & indie mainly), improvise, and generally be competent.

I also want to learn how to sightread, so I've been using https://sightreading.training which has been really useful! I have a background in music (guitar, mostly) and know music theory as well.

Unfortunately due to COVID, Delta, etc, I am not really interested in in-person lessons at the moment, so I was wondering if any tilde users had advice about learning to play through resources online or books!

I'm also really interested in any tips that anyone may have!

When learning something new, often available resources are lacking in some departments - whether they're missing information, poorly written, or tedious and dry. But occasionally, some content just stands out as above and beyond the rest, serving to not only make the learning process enjoyable but also to kindle interest in further exploration. What is that for you?

This could encompass everything from computer programming to literary criticism, and could be in the form of a website, book, video tutorial, or the like.

I'm a sucker for languages and lately I've been wanting to learn a sign language (not specificallly ASL as I put in the title, I'm open to learning any local flavour).

And well, with COVID and everything, I figure this may be a good opportunity to do this with someone else and have someone to talk to. So, is there anyone on Tildes who would be willing to have regular informal video chats, where we talk and you try to teach me as we go? (And of course I can accommodate by text if needed)

No hard commitment, this can just be something we try once and if it's boring for either of us we don't have to continue :) But I'm hoping it'll be fun enough to be a regular thing!

PS. I can teach you French in return if you are interested!

Stop me if you've heard this one before:

• You get an idea for something you'd like to learn more about. (Maybe you have a question, maybe you want to explore a new hobby, or maybe you want to make a more informed decision.)
• You type something into a search engine.
• You click a result, only to realize that what you're reading is poorly written. It seems rushed, surface-level, and ill-informed. "This doesn't answer my question at all!" you think to yourself.
• You go back, and try another one, and another one, only to give up and put the idea back in your head.

I don't think these webpages are written to be useful in the first place. They seem to be written to attract attention to the website for other reasons (ad revenue, affiliate links, to draw attention to a product or service). Regardless of why it's happening, though, I want to find a better way to search.

The sort of content I'm looking for is written by someone who really cares about the topic. I want to learn from dorks and nerds and passionate people. Once I stumbled across this blog about extra virgin olive oil. The website isn't pretty, and it goes way more in depth than I'll ever need, but I trust the author, and there are some really interesting nuggets of insight on these pages. (e.g. "Another myth debunked: Heating EVOO makes it ‘toxic’")

Do you have any tips or tricks to more reliably find these sorts of sources (whether online or in-person)?

Toki Pona is a minimalist conlang famous for having a vocabulary of under 130 words. There are communities of speakers on all major social media platforms. This is an introduction thread for speakers, learners or the toki-curious to introduce themselves. I'll advise on learning resources, or just answer general questions if anyone is interested.

I'm a toki pona speaker and creator of the YouTube channel 'seme li sin?' which translated news stories into toki pona.

mi wile e ni: kulupu wawa pi toki pona lon lipu Tetesu. jan ale pi toki pona li jan pona mi. sina ken la o kepeken e toki pona lon lipu ni!

I know those are easy to find on children's education materials, but the keyword here is simple. Anything kiddie, requiring too many clicks or that takes 3 seconds is off the table.

I kinda need to brush up on my super basic reasoning. In part, because a grown man should know the time table by heart, and in part, because I wanna convince myself that I did not get brain damage after being hit by a car (there's really nothing indicating that, I'm just paranoid).

I'm looking for something simple that presents me with the multiplication table and or simple calculations to answer under a time frame. The requirement for iOS is that my computer is broken.

And it really can be super simple, even something I open from a mobile web browser or transfer to my Kindle.

Additionally: there is no need for if to be an app. A huge list of exercises (with answers) would be greatly helpful.

Thanks!

I read the AskReddit thread on "What costs less than $100 that changed your life?" (link unavailable since I'm at work) but someone responded "SQL" - jobs just open up that make a ton of money.

I did a cursory search on Indeed and holy moly they were right -- SQL jobs get easily 2x what I make now. I'm pretty good at Excel and that sort of thinking, so I was thinking I'd try taking a class.

Do yall have any recommendations as to a good course to take in SQL, preferably online, preferably free or cheap? I'm willing to pay a bit if it'll mean I can make a lot more, but I'm currently not making a ton, haha.

Any responses welcome, including ideas as to how to break into like, tech-oriented fields as well.

Not leaving the house much these days (due to social distancing and also insane heat in NYC right now) means I've got some time to kill that I'd like to spend productively.

I took MIT 6.00.2x: Introduction to Computational Thinking and Data Science a few years back when I was refreshing my Python skills. I think it's been updated a bit since then. It was a high quality course and I enjoyed it, though there are so many Python-related courses these days, I can't guarantee it's the best.

I'm currently taking:

1. Model Thinking on Coursera from the University of Michigan. I don't know where I saw this recommended (maybe on Tildes or Hacker News?) but it's quite good so far. Scott Page teaches about how to use various models (mental models, computational ones, etc.) for breaking down and analyzing various problems and systems. I've only just started but I quite like it.

2. Testing and Monitoring Machine Learning Model Deployments on Udemy. Taking this along with a few coworkers since it's relevant to what I do. Only just starting but appears to be quite good and works through a well-documented example project on Github.

I've also come across a few that seem like they might be good courses for the future:

• Bayesian Methods for Hackers
• Probalistic graphical models on Coursera (3-part sequence, not free)
• Computational probability and inference

Now your turn: what have you taken? What did you like or not like, and why? What do you want to take?
