Cool Tech on my Radar

CockroachDB Ziglang WebAssembly

I like to learn about new technologies, and use those technologies to make my side projects more jank.

I believe that the best solution is most likely the simplest one.

My other interests include learning too many useless facts about anything anyone is willing to talk about. If there's some maths, science, or technology involved, I will probably be interested in it.

Some of my weekend projects would include photography, making something with my 3D printer, or making something with a microcontroller.

I have a forked/customized Dactyl Manuform Mini 3D printed keyboard with low profile Kailh Choc Sunset Orange switches.

Projects

ethernets.io

July 2023 - present

Took an unmaintained POC for an Ethereum network crawler, make it functional again, and added many new features. It's basically entirely new. I'm still working on it in my spare time/weekends.

The entire system, including Postgres setup, is defined in the Nix Flake in the project, and is running in a NixOS VPS.

ISTA Seed Sampling Calculator

April 2019 - present

A seed sampling calculator written in React.

The user searches for the seed they would like to sample, select the container type, and fill in the fields to get the sampling parameters.

Data and calculations are based on the ISTA rules document, which is 50 pages of rules, processes, and tables of data.

Also my first logo design

Features to highlight:

  • PWA (progressive web app), allowing the user to install it to their device and use in the field, where there might not be any internet connectivity.
  • Multiple languages. The user can choose between many languages, donated by the users all over the world. This is managed in a Google Sheet :)
  • Local storage for favourites.
