I’m working on a new way to talk online, with the goal of killing cancel culture, increasing understanding, and basically calming down current radicalization. Picture Reddit, but with the ability to anonymously share ideas with other people in your social circles. My theory is that most reasonable people stay off social media, so places like Twitter end up filled with unreasonable narcissists. At the same time, discu…

Are you trying to reinvent 4chan?

Let's solve Harmony! The first scientific experiment was conducted by 5th century BC Pythagoreans. They wanted to show that the basis for musical consonance was math. From that, they inferred that harmony in math accounted for the harmony of the cosmos. This integration of math+physics was very forward thinking. But, if we fast forward to the present, we still don't have a complete scientific explanation for the basi…

I worry from this brief description that you may be ignoring cultural aspects to our perception of consonance and dissonance. Also, harmony itself is a distinctly western concept whose musical role expanded dramatically with the advent of polyphony. Many (most!) musical cultures around the world don't give harmony much, if any role, and place higher importance on melodic structure. Also, music harmony and the other k…

I agree that the central scientific question is whether harmony is a metaphor or mechanism, e.g., for psychological constructs like Cognitive Dissonance. My guess is that harmony is so pervasive that it ceases to have original meaning -- like in the manner that every atom is a harmonic oscillator or how brainwaves are based on an "octave" structure (e.g., Beta is double Alpha, Gamma is double Beta, etc). However, this question of metaphor or mechanism should be resolvable with science, eh?

However, I disagree that harmony is primarily a western phenomena. It is a central feature to Confucianism and Daoism. It also plays a major role in Native American philosophy.

I'm trying to run jobs on a timer when the jobs are on a cluster and I don't know which server the job is assigned to.

It's essentially a problem of distributed timers and distributed transactions.

(If anyone has any resources on how similar problems have been solved in the past, I'd appreciate it.)

Automating cloud architecture creation. I'm building a "catalog" of architectures that you could use to create a complete cloud architecture on your AWS, GCP or Azure account in less than one minute. So, for example, you could create a docker-based architecture with CI/CD, auto-scaling, zero downtime deployment, SSL, load-balancing, high availability and MongoDB in less than one minute in your own AWS account. It's l…

This was my first thought. Terraform modules can accomplish all of this.

I am trying to build a humanoid with bunch of servos. Back in 2017, I bought 205 servos from a closeout sale. Currently, I am trying to hook them together and come up with basic APIs to control them. Next is printing a 3D model.

This sounds so interesting! Do you have a blog I could follow the project?

On that same concept I was recently thinking pvc pipes might be a cheap way to build robots. It’s cheap, somewhat light, and seems strong enough for many tasks.

Any thoughts on how to connect pvc pipes up to servos?

Also will your robot need feet?

I was talking specifically about harmony in a musical context as being very western.

We're writing too much code. So I'm making stuff that will help us write less code. Like a vim-like editor that translates your spec into generated code while you also see it on the go to fix any issues. Think yeoman on generics and steroids.

Like cucumber/gherkin but for production code?

In a way! More like emacs for trees + cucumber

I got a little lost when you tried to compare musical harmony to societal harmony. With regards to musical harmony, is it possible that it's more or less random? I know multiple cultures have different definitions of musical harmony. I suspect the evolution of hearing also contains random elements. Similar to language, it's not so much about an inherent universality, just a universality we can all learn and agree on.…

Check out your voice on a spectrogram app. See all the harmonics? Our voices evolved this way, probably due to sexual selection.

It's not so different between cultures, in fact.

Maybe not what you’re asking for, but this should at least give you an idea what to look for:

> editor that translates your spec into generated code Anyone old enough to be in IT in the late 80's/early 90's will remember the "4th GL" phase that swept through Fortune 100 companies. I was in banking at the time, and 'Focus 4GL' was brought in to replace programmers. Of course, in the end, it turned out to be a fools-errand. My prediction though is that in less than a decade, ML/AI will be decent enough at devel…

Not really - the generated code isnt some mystic code, it's simple templates.

I originally got there by making a complex magic data structure that held relations to everything in multiple dimensions so I could generate a huge amount of stuff, but that turns out to be just like 4GL - a load of slow confusion. The reason I am doing it is exactly because of ML/AI hope - with enough data and proper structures, I can generate a lot.
