My suggestion would be to experiment with languages until you find one that you like more than the others and replicate the functionality of someone else’s software. Free yourself of the need to come up with a good idea.
If you choose a language that’s not widely used or no one is hiring for, don’t worry about it. You’ll find that the concepts you learn in any language are portable to all languages. Once you learn those, it will be easy to pick up new languages when you need to.
Bonus advice: when you find a language you’re good at, stick with it and get really good at it.
The chassis is 3D printed and a Raspberry Pi is hiding, with a couple of speakers, in the base. The Pi connects via WiFi to the local network and checks ESPN’s publicly available JSON for that day’s game to determine if the score has changed.
I gifted it to a friend that owns a bar and wanted him to be able to move to new networks and reconfigure without using a computer. So, I wrote some python scripts that interface with the GPIO pins on the Pi to reset the device and broadcast a WiFi network and web interface that can be used to connect to other networks.
Google will give a relative measure of how busy the space currently is but doesn't give an exact number or a sense of how full a location is relative to any temporary capacity limits that might be in place.
This is a simple web site that I put together for small businesses that want to keep crowds small and avoid lines at their businesses while running at a limited capacity. It includes a simple app to keep tally which is then visible to people searching for you.
It's totally free for all to use and any feedback is appreciated!
