Retrospective Overview & Key Insights

Distilled reflections, business mechanics, and tactical takeaways:

In this technical retrospective (2025), @jgrahamc shares practical architectural lessons learned from running, scaling, or migrating production software under lean constraints.

Core Principles for Independent Builders:
1
Defaulting to simpler architectures (such as monolithic frameworks, SQLite, or managed VPS) prevents early engineering bankruptcy.
2
Evaluating true compute and egress costs reveals that high cloud bills can often be slashed by 80%+ through judicious re-platforming.
3
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.

I don't understand:

all of the prompt tokens are available in advance and do not require decoding
The other technique is called batching: this technique aggregates multiple prompts into a single decode operation.

So do prompts get decoded or not? Are there 2 decode steps? Unclear
