Thanks for the feedback - it should be fixed now :)
I recently saw this website on Show HN: https://newsandrumors.com
It seems relatively simple to implement, and the costs would be near zero since we are just fetching/storing RSS feed data.
It's implemented but not yet integrated (need to cache the ecb rates first).
For instance, there is no lang attribute, buttons don't have accessible names, etc.
Implemented a simple version.. but I've been thinking that we should implement a more advanced version, such as Rob Pike's APL-like calculator. This would need to be done either on client-side with JS or through e.g. a Google Cloud Function. I'm personally leaning towards the latter.
The initial version should just calculate on the server and present the result. In the future we might add an actual calculator similar to what you see when googling 2+2..
Added an in-house solution that support a few instant answers, such as hashing text, url encoding/decoding, picking a random number between x and y, etc. Still many, including my favourite (currency conversion), on the to-do list.
