Hey everyone, just watching a very interesting history of Terry A Davis (creator of TempleOS) and around the 30 minute mark there is a list of questions Terry asked to God and the answers he believed he received. I took a look online but was unable to find anything. I don't suppose anyone out there has a link? I'd be very interested to read it. Thanks in advance.
EDIT: I'm also interested in any links to the art he created (hymns, visual art etc).

I recently came across an article about setting up automated builds (installation, code quality check, running tests) using Github Actions. I've since found a few more articles excitedly promoting the feature and, from my personal testing, it seems to work quite well.
I was wondering if others had begun using this feature for their own projects, or had tried it and disliked it and used something else. Is there any broader community consensus towards which tasks it's best-suited for and when to use something more robust?

I'm interested in C or Go, but i'm open to ideas.
I have plenty of sh scripts i created to integrate my tools and system, so i have some experience and i don't want a scripting language like python.
My first plan is to learn the basics of the language and rewrite some of those scripts.
I think my first pick will be a script that uses ffmpeg to convert my flac files to mp3 or opus. I use sndconv -opus/-mp3 and it checks if there are flac files in the folder (i only have full albums), converts and puts in a folder named "$artist - $album".
My long term goal is to make a cli/tui music player like cmus.
UPDATE: i'm having plenty of success with Go right now. I just wrote a basic version of my music conversion script. It's just converting a music i pass as argument to mp3, but i'll keep working on it and adding functionality just to dip my toes in Go. It seems like a good language and i'm having fun!
Thanks for all the answers!

There's no doubt computer science is indeed a science, but what about programming itself? Does it fulfill the basic requirements that make something a science? I'm not an academic, just trying to start a conversation.
In many ways, programming is like Math: a means to an end. And Math is a science. Like math, programming has several fields with vastly different ideas of what constitutes programming. Because it is applied logic, programming is also provable and disprovable. There are many disputing hypothesis and, even though absolute truth is a distant dream, it is certain that some sentences are truer than others. Again, like Math, Programming has many practical applications, such as finances and engineering.
Some people consider Math a propaedeutics: not a science in itself, but a discipline that provides fundamentals to actual sciences such as chemistry and physics. The same reasoning could be applied to programming, as nothing more than a tool for computer science. I personally think there's something unique about programming and it's problem-solving methods that can be considered a field of its own.
What you guys and girls think?

Hi everyone! It's been a long time since last programming challenge list, and here's a nice one I've encountered.
If you search for something like 7km to AU, you'll get your answer. But how is it done? I don't think they hardcoded all 23 units of distance and every conversion factor between them.
If you were programming a conversion system - how would you do it?
First of all, you have input in format that you can specify, for example something like this:
meter kilometer 1000 mile kilometer 1.609344 second minute 60 ...
Then you should be able answer queries. For example
7 mile meter
should convert 7 miles to meters, which is11265.41
.Can you design an algorithm that will convert any unit into any other unit?
Edit: Some conversion rates I extracted from wikipedia:

I decided to post this as a text topic since IMO the video description is really important to understanding this performance:
Aug. 29, 2019 | Colin Marshall -- Dan Tepfer has transformed the acoustic piano entirely with his new project, Natural Machines. Watch the keys and you'll see this Disklavier — a player piano — plucking notes on its own. But it's not a prerecorded script.
Here's how it works: Tepfer plays a note, and a computer program he authored reads those notes and tells the piano what to play in response. Tepfer can load different algorithms into the program that determine the pattern of playback, like one that returns the same note, only an octave higher. Another will play the inverted note based on the center of the piano keys. These rules create interesting restrictions that Tepfer says make room for thoughtful improvisation. In his words, he's not writing these songs, so much as writing the way they work. To better communicate what's happening between him and the piano, Tepfer converted these audio-impulse data into visualizations on the screen behind him, displaying in real time the notes he plays followed by the piano's feedback. We dive even deeper into this project in a recent Jazz Night in America video piece.
Perhaps the trickiest part here, unlike a human-to-human duo, is that the computer plays along with 100 percent accuracy based solely on Tepfer's moves. He compares it to dancing with a robot that never misses a beat. Tepfer has to play in kind to keep the train on the tracks, but if he falls out of step, so does the computer. On the other hand, Tepfer has unlocked a new frontier of music available to acoustic piano players: He's essentially given himself more limbs to play the piano at once, and at times we see more than 10 keys pressed at a time or a sequence of notes played at seemingly superhuman speeds. It's a central idea to what innovative technology enables for us — that which is impossible for us to achieve on our own.
edit: Nice related video from Jazz Night in America with Dan explaining some of how it works:
