savethepictures VS rtpmidid

It's a super simple time series data storage. You don't even have to register an account, just do "curl -X POST https://pushdata.io/[email protected]/temperature/47" and you've stored your first value. I use it a lot to log various stats about all the things I've built, like user signups or whatnot.

Then I wanted to create simple crosswords with image clues to help my kids learn to read. That resulted in a crossword generator backend and a simple game: https://puzzlepirate.net

Puzzle pirate is great, but I wanted to print the crosswords on paper also, so I slapped together https://crosswordcomputer.com. The UI is rather ugly (like Pushdata) but you can create pretty cool crosswords for kids with it.

Then I wanted to create more flexible shields.io so I created https://supershields.io - basically a shields.io but with programmable (in Lua) logic for the shields you create. I'm not using it myself anymore though so not maintaining it very well and it seems there is something funny with the Lua execution right now. It is using AWS Lambda servers to run Lua scripts, perhaps they're not firing as they should or something. If someone wants to use it, get in touch and I'll see if I can get the Lua execution operational again :)

I also wanted to backup private photos and videos from household phones to a USB memory on a local storage server (Raspberry Pi) and then have that server automatically back everything to the public cloud but encrypted (as I don't trust public cloud providers to keep my data safe forever). I couldn't find a good solution for this, so I wrote some shell scripts that do the trick: https://github.com/ragnarlonn/savethepictures

My daughter was playing Minecraft too much, on our own server, and I created a small Python program to enforce "screen time" in Minecraft: https://github.com/ragnarlonn/mctimer

I once needed to simulate broken DHCP clients and couldn't find a good tool to do so, so I wrote "dhcptool": https://github.com/ragnarlonn/dhcptool

All of these taught me a lot, especially the later forays into full-stack development after having been pretty much clueless about frontend stuff for a long time (still clueless but at least I can create ugly UIs now).

rtpmidid[1]. After getting some hardware synthesizers and wanting to connect them without using a computer.. but being able to use them too using the computer I stumbled upon with rtpmidi the protocol and it ticked all the boxes I needed. I could connect all my gear to a raspberry pi, use ALSA sequencer to connect devices to each other with another of my programs AseqRC[2], and then use my synths from my DAW without touching any cable.

So after a fast prototype I created rtpmidid and I'm quite happy on how it works.

And it also helps with the USB ground loop noise that it seems unavoidable some times.

For some time I had even two Orange Pis connected to two sections of my gear, using USB gadget support so my MPC One could speak rtpmidi. MPC One has support to connect as host to MIDI devices, but as guest (connect to the computer) only in controlled mode which is not what I needed to convert my MIDI tracks to my DAW.

My hope is that they finish the MIDI 2.0 rtpmidi protocol, and that starts to be truly used in real hardware, not half used as current rtpmidi.

This would allow easy connectivity with very low latency over normal LAN, including switches, power over Ethernet...

Disclaimer: I created a rtpmidi implementation for linux https://github.com/davidmoreno/rtpmidid

I've been using rtp-midi, using rtpmidid and it's working fine.

I'm trying to figure out how to use rtpmidid by David Moreno with my iConnectivity Mio XL. Just running rtpmidid makes all ports show up in Carla and in Reaper, but no MIDI seems to be sent. In Bitwig i can't even see the ports. Maybe because it uses jackmidi and rtpmidid uses alsamidi?
