If anyone else is looking to migrate from Celery to DBOS, we also made this transition and wrote about it https://dosu.dev/blog/migrate-celery-to-dbos-dosu

Very happy we made the switch.

Ask HN: Natural Language App Testing?

devstein — Tue, 19 May 2026 22:35:35 +0000

Hey HN - we're contemplating building our own E2E natural language test framework.

I figured someone else must have built this already. Who are the established providers in this space? Does anyone have recommendations?

What top K do you use for vector search before passing into the reranker?

Ask HN: Best Embedding Models?

devstein — Tue, 05 May 2026 03:15:10 +0000

Hey HN, which embedding models are people using? There has been so much development around foundational LLMs, but haven't seen much news about embedding models.

Ask HN: Does Continuous Pen Testing Exist?

devstein — Mon, 27 Apr 2026 16:59:59 +0000

Hey HN - it's time for our annual pen test.

We typically work with a 3rd party security firm each year, but now I'm wondering if there are more efficient and more AI-native options that people are using? It seems like a clear use-case for agents. Does anyone have experience working with a product/vendor in the space?

I think the only way to keep documentation up-to-date is to have it as part of the PR review process. Knowledge needs to evolve with code.

We working on this at https://dosu.dev/ (open to feedback!)

I believe this is why the importance of written (human) knowledge is only increasing, especially internally at companies. Written knowledge (i.e documentation) has always served as a knowledge cache and a way to transfer knowledge between people.

Without fundamental changes to the LLMs or the way we think about agentic systems, high quality, comprehensive written knowledge is the best path to helping agents "learn" over time.

^this, but many non-code documents with manual steps can also be kept up-to-date as long as there is a way (a) relate it back to the codebase or another source of truth (b) detect conflicts (when someone says something in contradiction to an existing document)

Ask HN: Is Supabase's Supavisor slow for anyone else?

devstein — Fri, 15 Aug 2025 23:12:10 +0000

Since June of this year, we've noticed a spike in latency for DB queries routed through Supabase's Supavisor.

Direct DB queries will take a tens of milliseconds while queries through Supavisor will take a minimum of 200ms and up to 5s.

This is phenomena independent of the underlying query even `SELECT 1` through Supavisor can take up to 5s.

Has anyone else experience this before? Is this a known failure mode of Supabase's Supavisor?

Couldn't be more spot on. This is exactly why I started Dosu https://dosu.dev/ to reimagine on the "knowledge" side of software engineering.

New comment by devstein in "Ask HN: Given the choice, would you write documentation if you didn't have to?"

devstein — Wed, 02 Apr 2025 01:00:21 +0000

I agree about docs as a tool for thought.

What about the other side of docs, keeping them up to date?

Ask HN: Given the choice, would you write documentation if you didn't have to?

devstein — Tue, 01 Apr 2025 23:50:51 +0000

I personally find writing internal documentation very monotonous even though I know it's important.

I'm curious if you were told you could have decent internal documentation automatically generated for you that were good enough, but not competitive w/ human maintained docs.

Would you still take the effort to write your own documentation?

New comment by devstein in "Anyone know who is generating AI bug reports to popular OSS projects?"

devstein — Thu, 23 Jan 2025 18:23:20 +0000

There has been an influx of AI-generated bug reports to popular OSS projects. It's unclear if this is malicious or someone built a tool with good intention that is now causing maintainers to be inundated with issues.

Has anyone stumbled upon an AI tool that helps submit bug reports to OSS project?
