#WIP - Calculator Pond

Online calculator utilities focused on accessibility and optimization.

#Goals

These are what I aim to achieve, but will probably be pretty far off for the time being.

→ User experience

• Accessible — too many online uilities with glitchy interfaces and too-small click targets.
  • Snappy — with the help of JavaScript, but just enough, no more
  • Works without JavaScript — Equal functionality though with speed tradeoffs requiring an extra reload.
  • Works on text mode clients
• Just the functionality — no ads or unrelated distractions
• Simple interface — perhaps opinionated; not quite brutalist, but satisfactory — modern looks without stacking bloat and excessive web design
• Speed

→ Developer experience

• Zero dependencies
• Readable codebase
• Go backend (using net/http) with plain old HTML+CSS+JS frontend. No need for fancy frameworks or fresh new bleeding-edge technology
• Modular and extensible

#Development

Only a fairly recent version of Go, a reasonably sound programmer's brain, and a usable text editor is required.

Optioanlly use air for hot-reloading.

#Plans
