I built a tool that auto-suspends idle AWS instances and tracks the savings
No buzzwords. No "AI." Just what it does.

#742I made Beacon, a mobile app for answering: “which of my friends is free to talk right now?” It’s basically a one-to-many phone call that only one person can answer. Send a beacon to a group, and everyone gets rung at the same time. The first person who answers gets connected for a 1-1 call, and for everyone else the signal drops silently. No missed-calls or pressure to answer. Works pretty well given most people keep…
Ooh this is such a cool idea.

I'd love it if you can also fix the problem of timezones. So many of my friends are oceans-apart and we rarely rarely meet and talk as a group anymore. Maybe some kind of asynchronous option?

#747I'm building an RF monitoring system. It can tell you things like: - The car that parked nearby last night coincided with "Chad's Galaxy Buds" with MAC address aa:bb:cc:dd:ee:ff. The buds also drove by briefly the previous night. - Alert on sudden cross-specturm interference (e.g. burglars using a cheap jammer to knock out WiFi cameras). - Alert on known device contact loss (powered off / left premises). - Review dev…
Very cool. Do you happen to have any kind of mailing list, blog, etc?

#748I spent the last 6 months building Elk Finder (https://elkfinder.com) and just launched a few weeks ago. It's a mapping web app similar to onX Hunt, except I have specific layers for finding ideal elk habitat in September and October (the primary archery and rifle hunting months).

#749Been working on an open source, free, Heroku alternative at https://canine.sh for about two years. Its basically a one-click install against a Kubernetes instance to give you a Heroku interface.
I feel like even after all these years we’re still missing the devex that Heroku provided.
Canine basically wraps a Kubernetes cluster -- gives you a heroku like interface to deploy applications to. At some point, if you get big enough that canine is no longer powerful enough, you can just "eject" canine from kubernetes, and continue using kubernetes directly, without having to do any migrations.
Just passed about 2000 developers, at this point most of my work is resolving bug fixes, adding helper text everywhere to make things cleaner, and supporting setups I've never encountered like homelabs with changing IP's

#750I have been building few tiny financial apps for analyzing the market, domains and stocks to see if I can use them to make investment decisions.
Adding small tools to help understand specific option strategies, and once executed understand optimal action (exercise early, let it expire, wait)
Personal tools, for my use. No commercial angle in mind.
