A TUI client for Confluence

A script that does a speed test of my Internet connection once an hour and plots a graph

A financial analysis webapp that barely works

I call it meware: works for me, and hopefully for someone else, too, but it's not polished.

I built a hydroponic garden as a covid hobby. I wrote software to maintain the garden, water it on schedule, apply ph changes to the water, turn lights on / off, humidify, as well as monitor statistics (temperature, humidity, water temperature, water ph, water conductivity). Rough guess would be that I spent 50 hours actually working on the software. There's a handful of raspberry pis involved. I wrote everything in…

This sounds like a great project to reconnect one with growing food… with some perks.

Appreciate you sharing, helps share others are thinking about it too.

Is there a reason you went with hydroponics vs aeroponics?

I recently made a cli chatgpt interface. Quick hack in Rust, always planned to clean it up, not entirely sure where the source code is for it anymore but I use the compiled binary all the time. The regular chatgpt interface is nice but sometimes don't want to break out of the terminal.

Did you get ChatGPT to help you write this and is one of your main use cases generating bash commands? (Code writing code, there’s a total feedback loop happening here) I did too but wrote mine in Python. A compiled language would be much faster and using their streaming function I’m yet to implement. Any other ways you can increase the speed?

I don't think language would matter much as the primary delay is getting a response from OpenAI apis. The advantage of Rust (or other similar language) is you get a simple single executable. Otherwise Python is completely fine.

I basically use this any time that I am in the terminal already and have a question that I think could reasonably be formatted fine there. I'd say, I use it for 30% (conservatively) of my ChatGpt queries. Naturally the web interface is way better for lots of stuff, but sometimes breaking out of a terminal session is jarring.

What do you use for valve automation? Is it a commercial or custom part? I've been wanting to do the same myself, but I hear there's all sorts of quality issues with automatic valves.

I originally bought some solenoid valves to experiment with, but ended up simplifying my approach. I use a submersible pump that is plugged in to power. I can just automate turning on/off power to that outlet (I have two TP-link / Kasa HS300 strips). The nutrients / water are in a tank below the tray of plants, so when the power is "off", gravity brings the water back through the pump into the tank again.

I wrote a program "syncdir" that will synchronize two directories. I use it every day for making backups. I originally wrote it for DOS eons ago.

This reminds me of Microsoft's sync toy:

I wrote a hacky PHP web app that allows me to generate 5" Optical Media artwork for imprinting using a inkjet disc printer. My script loads it's own truetype fonts (to stay on brand) and produces print-caliber artwork in milliseconds, instead of minutes. I spent a single day mastering it, and have used it weekly for decades, saving untold hours of effort. Alas, this side of the business is failing due to lack of demand (who has an optical drive anymore??), so this code will also die someday.

Almost all of the software I make in my free time is for my own use. My most used tool I have is a note taking web app that automatically saves markdown files to S3. The most important feature I added was a little button that would automatically make a note for the current day, and put it in the daily notes folder, all sorted and organized. I also have full text search which is very helpful for finding old notes. I a…

Sounds like you'll be better served by obsidian. The free plan covers all those use cases and more

How does it automate ph changes to the water?

I use two pumps from Atlas Scientific - one for a jar of base and one for a jar of acid. I have a sensor for PH so I can see in the live dashboard, and can click a button on the dashboard to disperse a set number of ml to the tank. I should have been clearer - PH is the one thing I didn't "close the loop on" because it'd be a little volatile. For instance when you first add nutrients to the water the PH drops steeply but stabilizes over hours or a day, I didn't want to respond too constantly to those changes. I should spend more time on this aspect though and maybe just have notifications for when it makes decisions.

I wrote an app to log mileage while doing deliveries, etc for my small business. It gives me a small tax benefit at the end of the year. To make it more fun, I gave the UI a "terminal" flair.

I wrote it over the course of a week or so and I use it frequently.

It's not that it won't see the light of day for anyone else but it's a very specific niche so I doubt anyone would even find it on the app store
