Shoutout to the [wasm-bindgen](https://github.com/wasm-bindgen/wasm-bindgen) maintainers who do an awesome job of allowing Rust to be compiled to WASM smoothly. I built an [eigenvalue solver](https://abstractnonsense.xyz/blog/2025-12-31-eigenvalue-solv...) in Rust for an interactive component for my blog, and it was super smooth going. Felt like magic! I've noticed that the binary sizes can blow up a bit by including libraries, but if you're careful I think the binaries are pretty small, tbh.

In Australia, the Reserve Bank is finally [banning surcharges](https://www.rba.gov.au/payments-and-infrastructure/review-of...) from October 1st. We also have the EFTPOS network, but the payment rails change depending on the card payment method.

Over the years, the "hidden fees" were accumulating, and card surcharges could hit 1-2.5%. Now, _most_ places don't have any fees (with some food places charging weekend surcharges and some egregious places adding unsolicited tips).
