format-hero VS tlssh

I created "Kid Money Manager", a tool to help manage my son's virtual account. He wasn't old enough to open his own bank account when I started, but we needed some way to track his "earnings" (returning bottles for their deposits or gifts from grandparents) and spending. It has both a Web UI and access via SMS text messages. We mainly use the text messaging—entering transactions at the store, etc.— since I didn't want to write a dedicated phone app for such a simple interaction.

Created it from scratch, live coding it on my (JitterTed.Stream) Twitch channel (and some videos on my YouTube channel at JitterTed.TV). Written using TDD in Java + Spring Boot, deployed on Heroku and open-source at https://github.com/tedyoung/kid-bank.

I also recently wrote "Format Hero" (https://formathero.dev), because I could never remember which letters to use in Java's DateTimeFormatter. Was also a good demonstration of Hexagonal Architecture and, of course, I live coded it, TDDing all the way. Source is at https://github.com/jitterted/format-hero. Still some work to do on that one, but filled my immediate need.

And then plenty more than I use occasionally, and some I no longer use. E.g. for a while I used my own SSH replacement, in order to get TPM-backed keys (https://github.com/ThomasHabets/tlssh). Nowadays I use yubikey instead (https://blog.habets.se/2016/01/Yubikey-4-for-SSH-with-physic...).

Those are just the main ones (as in not small, and used every day). I find myself fixing problems all the time by writing code.

A curious question. Aside from my day job, this seems like a thing I do all day. :-)

I'm not sure what the motivation for your question is. Do you feel like everything's been invented and built already, and it's just a matter of (at most) plugging the things together?

I find myself constantly thinking "this should exist". I don't have time to make them all exist.

Nothing like it existed at the time, and I wanted to send ARP requests as easily as sending ICMP ping.

I wanted to use a TPM chip for SSH client keys, and couldn't find anything like it.

I wanted to explore what it would be like to have SSH, but with identities not based on providing username, but an x509 cert. (and TPM chip protecting the key)
