Bare Metal WASM
In this technical retrospective (2020), @markdog12 shares practical architectural lessons learned from running, scaling, or migrating production software under lean constraints.
Core Principles for Independent Builders:
Defaulting to simpler architectures (such as monolithic frameworks, SQLite, or managed VPS) prevents early engineering bankruptcy.
Evaluating true compute and egress costs reveals that high cloud bills can often be slashed by 80%+ through judicious re-platforming.
Code you write at 2 AM as a solo engineer must be easy to debug six months later without complex microservice dependencies.
Community Debate Themes:
HN engineers debated the tradeoffs between cloud convenience and raw server economics, database indexing strategies, and resisting premature architectural complexity.

If you're thinking that this is an article about 'Bare Metal WASM' as an OS sandbox, you should probably think again; Hard.
So nothing about actual 'Bare Metal' using WASM. Just Rust cross-compiling to WASM using 'wasm-unknown-unknown'. Title should be 'Cross-compiling web apps to WASM.' rather than this misleading title.
