Your digital notes will probably be around much longer than any specific system you use for a while. The tools you use now should not lock you in when later on you decide to move on (with your notes).
Arachne.nvim is a minimal, low-tech notetaking system for Neovim. It doesn't lock you in, you can use your notes with whatever you want. Arachne.nvim also works well with other tools - have a look at the github page if you are interested in an example setup that shows Arachne being used together with Telescope, ripgrep and fuzzy searches. This is the setup I am currently using myself!
Our guest dog, that we take care of now and then (as often as possible), developed an allergy to grasses. The poor guy. To be better prepared, I build this little dashboard that shows the pollen levels, including a 6 day forecast. It also works for humans!
Have a look at oem.github.io/pollen.
Let's nerd out for a second :) The frontend was done in Elm, which is a delightful entry level drug to (pure) functional programming! It's also small, fast and absurdly robust, especially considering that it has to live in the very hostile browser environment. The data collection and cleaning was a breeze with julia, a language my brain seems to like a lot! All of this is hosted on github, a github action will run the julia code every now and then to fetch and clean new data and commit the updated dataset. The frontend will request the committed dataset file directly from github. Oh, and is hosted as a github page.
We should strive to make informed decisions, especially when dealing with a pandemic. This dashboard is color-coded to make it very easy and intuitive to get a quick summary of the current covid situation. Like checking the weather.
You can find the running dashboard at oem.github.io/covid19.
Under the hood it is very similar to the pollen level page, it uses julia to get the data, Elm for the frontend and github for hosting and updating.
