I have a small YT channel [1] and I used to spend 30-40 mins recording and then 2-4 hrs editing to get a final 10-15 min video. Then I fully scripted my video editing using Python+MoviePy [2]. The time savings are sweet. I just feed it my raw video and get the finished video a few minutes later. It cuts out all the dead air as well as the parts I don't want (which I indicate in-video). In general scripting video edit…

I personally know a few people who could very likely be your customer,so I second other commenter: do release it as a product.

Thanks for the kind words.

Script is open for anyone to use or adapt. Credit and link back would be nice :-)

"as well as the parts I don't want (which I indicate in-video)" How do you indicate that in the video?

Well, https://youtu.be/Bdoi7BDhrWc explains that with a demo.

But tl;dr-- after a segment I want to keep, I switch my background to solid green; after a segment I want to drop, solid red. (Segment == clip between two solid red or green backgrounds)

I made stylus to manage my home network with a Raspberry Pi. It requires barely and resources [!] any can manage anything that can be talked with via a shell script (including SNMP).

[!] I run it on a Pi0 and it takes negligible resources on that.

I built a music "scrobbling" program called rescrobbled to submit music I listen to Last.fm. I was sharing a Spotify account so I couldn't use Last.fm's Spotify integration -- which is pretty bad anyway, in my experience. Rescrobbled has served me well (and a few other people too, apparently).

I have so many of these things that I use daily.

I made a CLI password manager in Bash. It grabs random bytes from /dev/urandom, filters out the non-ASCII, then GPG encrypts with my key. Months later I realized I had reinvented the common utility 'pass'.

I made a utility to type accented characters on Linux. I learned to type French on an English keyboard under windows as a kid using Alt + 0NNN where NNN is the decimal character code. I made a delightfully hacky solution: when I press Alt+0 a tiny window is popped for a fraction of a second to capture the next keystrokes. If they are 3 digits, it spits out the relevant character into the active window. This one is also in bash.

The car share service I use got rid of their web interface. I reverse engineered their android app and created my own unauthorized web app so I can find available cars.(evofinder.ca)

I built an embedded device that connects to the door buzzer in my apartment so I can let myself into the building. It's built with a cheap esp8266 dev board and programmed with the arduino IDE, yet it has been running reliably for years.

I built a mobile trivia game web app that is simple and lightweight with no ads or tracking. I made it pre-COVID to kill time when I was out and about. (Justtrivia.fun)

I often want to run small "experiment code" many times with different inputs, but don't like wrapping everything in a big framework to do it. So I wrote a little tool that calls any command-line program multiple times with different inputs according to a template and a search strategy [1].

Another upside is that most parameter search programs seem to assume you want either grid search (which is hideously inefficient for large search spaces) or bayesian optimization (which can be overkill and comes with its own caveats). I wanted to make it easy to use quasirandom search [2], which is basically always the right choice for small searches where you just want to understand the parameter space better.
