The Self Balancing Monorail

My mind is blown away by this video! 🤯 I wouldn't have believed if someone told me they made this shit work today, let alone in 1910. Sometimes the ingenuity of humans is unbelievable!

Here is also a #Wikipedia article about it - en.m.wikipedia.org/wiki/Gyro_m…

@AntennaPod surprised me with this cool feature today!

I think Spotify had a similar feature for the songs you listen to, but I haven't been on Spotify for a long time so I don't know what it's called now. But it's cool to see this on a FOSS podcast app like #AntennaPod, and the amazing thing is that they generate it locally on your device so it's privacy friendly 🙂

A Round Disk Through a Smaller Square Hole (Bending Spacetime)

TIL after watching this video that spacetime curvature doesn't actually mean it's bending into the 4th dimension, all this time I thought otherwise 😅

I feel like the puzzles are getting a bit too hard for me on #AdventOfCode, so I'll probably be slacking off from now on. Solving last day's 2D pipe maze with a loop was hard enough, and today's puzzle seem to be of a similar kind so I'll probably skip - I feel like these puzzles have more to do with math and geometry than programming itself :blobcatshrug:

@bignose I can't summon up much enthusiasm for AoC this year. I don't need to:

* Learn a new language
* Learn to program
* Write yet more string parsing code
* Wrestle with algorithms that are vanishingly rare in the real world
* Prove anything, to myself or others
* Invest time/energy I could usefully spend elsewhere

But I'm delighted others enjoy it at least as much as I've enjoyed it in the past. Plus it's a great spectator sport.

This was actually my first year trying out AoC, as a beginner to programming it was kind of a fun learning experience, but being a beginner also means I'll have to stop sometime as the puzzles get harder. Last day's puzzle was a bit too hard for me, maybe today's is better I might give it a try but I certainly won't put any pressure on myself 😄

I thought my code is never going to terminate, but after around an hour or so it did, LMAO 🤣

Because I had to refactor the code many times for this one my current iteration doesn't make much sense, so I'll publish it later maybe after doing some cleanup, IDK...... It's all spaghetti code anyway :blobcatgiggle:

Well, after timing it I see it's not as bad as an hour, but 12 minutes is still too long for a program to finish running - in my mind it felt like an hour. Also note that this is a compiled language, LMAO 🤣

Advent of Code - Day 4 (Part 2)

Update: I've made the code a lot more faster by following a tip by @sotolf. Basically now the program is doing a reverse brute-force by starting at the end point and working its way upwards. So now the code finishes running in about 2 minutes, but if you use the --opt:speed compiler flag in #Nim then it can finish in 20 seconds! For comparison, my previous code took 12 minutes to finish even with the compiler flag on!

How should regulators think about "AI"?

I was watching this video by @emilymbender and she made a lot of great points there, highly recommend watching it if you're curious about #AI and the hype around it. I was a bit surprised when she brought up magic 8 ball because I've been jokingly calling chatGPT magic ball in my friend circles, but it's such a great analogy tho 😄

@amin yeah, that's exactly how I'm thinking how can I represent the data, and then how can I get closer to what I want, or functions I need to do what I need. My way is just one way to do it, but it's the one I find the easiest to work with :)

Types are a bit daunting in the beginning but when you do they really help you think, and let's the compiler help you not do a quite big group of errors :)

Sidedoor - Cellphones Rock

Listen here: play.prx.org/listen?ge=prx_69_…

One fascinating fact I heard on this #podcast episode:

> If everyone in the country use their phone one year longer on average, it'd be the same as taking 636,000 gasoline powered cars off the road.

The episode mainly talks about the precious minerals in our phones and how they're extracted from rocks formed millions of years ago, not only do we have a limited supply of these minerals but it also can't be recycled properly.

Unsung Science: The Man Who Invented QR Codes

In 1994, Masahiro Hara got tired of having to scan six or seven barcodes on every box of Toyota car-parts that zoomed past him on the assembly line. He wondered why the standard barcode from the 70s was still used...Why couldn’t someone invent a barcode that used two dimensions instead of one that could work from any angle or distance, even even if it got smudged or torn?

And so, studying a game of "Go", he dreamed up what we now know as the QR Code — the square barcode you scan with your phone. It shows up on restaurant menus, billboards, magazine ads — even tattoos and gravestones. But even that, says Hara-san, is only the beginning.

De Fiets is Niets

99percentinvisible.org/episode…

Today the Netherlands has a reputation as a kind of bicycling paradise. Dutch people own more bicycles per capita than any other place in the world. The country has more than 20,000 miles of dedicated cycling paths. International policymakers make pilgrimages to the Netherlands to learn how to create good bike infrastructure.

But none of that was inevitable. It wasn't something that magically emerged from Dutch culture.

In fact, in the 1960s and 70s, it looked like the Netherlands would follow the same path as the United States. The Dutch had fallen in love with cars and they were rebuilding their cities to make room for them. It was only because of a multi-decade pro-cycling movement that cars didn't take over the country entirely.

PDF files can contain malware in them which is why you should never open them if you get a spam email or something with an attached PDF. However I'd be very surprised if SciHub contains any malware like this person says because it's generally considered as a trusted source of information, without providing a valid source for that claim I can only take it as rumor or propaganda at best.

I really enjoyed this podcast episode because I've actually pondered about this question myself before, just like the 11 year old who called in and asked them. Considering the wide range of activities we humans can do just with the energy we get from our daily meals, it really makes you wonder how efficient we are as a species, compared to machines, other animals, etc.
