| Been building an automated test builder and an agentic API

|
| tl;dr: A 60fps embedded browser on the frontend lets you record
| manual steps and AI-driven steps (to assert/extract data). It
| then turns those into test suites. Any test with AI queries can
| auto-generate an API to be queried later.
|
| Right now, I'm working on an agentic API builder. Example use
| case: Say you need data from Salesforce and JIRA -- you log in,
| navigate to what you need, add an AI query step (or select
| elements manually), and set an update interval. The system then
| handles extraction and monitoring.
|
| Why? Because at all my previous jobs, suggesting hiring QA
| engineers would get you laughed out of the room. But testing was
| desperately needed, as well as internal tooling. Burning
| developer/CTO time on wrangling multiple complex API's just to
| build some internal tool would take much longer without this. So
| I'm working on something that makes both vastly simpler for small
| teams. Hoping to have a workable demo next week!

|
| (There are libraries/packages out there that implement VST in

| Still plugging away on my linear genetic programming experiments.

| The big debate in my head right now is whether a next byte

|
| The benefit of next byte prediction is that we only expect 1 byte

| The implication here is that the program probably doesn't need a
| whole lot of interpreter cycles to figure out this single byte
| each time (given reasonable context size). However, the downside

|
