rgbrgbon Show HN: HelixDB – A graph database built on object storage

congrats on the launch! site and docs look great.

can you host this yourself or do you need to use helix-cloud? the chat thing on the side seems to push me to helix-cloud but it looks like that starts at like $600/mo which is above my experimentation budget.

looking for a db for an agent memory application and i'd probably start with something that's just self-hosted / freeish. postgres is working ok but I want to start ingesting server and chat logs.

rgbrgbon Show HN: RePlaya – self-hosted browser session replay with live tailing

very cool. session replays are so crucial for understanding new features qualitatively, especially before you have enough users for useful quantitative metrics.

ballpark, how much does this cost to run?

rgbrgbon Please don't spam people looking for employment. It's just cruel

fwiw my experience building a small tech talent agency / recruiting shop disagrees with this. Cold application pipelines are overwhelmed by gen AI applications and many of the (very qualified) candidates we place report getting totally ghosted on all cold applications - even when we’re able to get them several interviews a week with companies in our network.

Seems like companies still value a curated pipeline. 15-20% of first year salary (numbers we see these days) appears to be worth saving the company time interviewing unscreened candidates. Recruiting can be a real time suck and a bad hire can be catastrophic.

rgbrgbon Show HN: Agent.email – sign up via curl, claim with a human OTP

Congrats on the launch!

> Agents can now get an email inbox by themselves. (This also means a lot of email nobody wants to read gets processed by AI instead of your inbox being cluttered with spam and slop)

Can you explain this? I would think it means the exact opposite.

rgbrgbon Show HN: Gigacatalyst – Extend your SaaS with an embedded AI builder

i love this because it seems like you've turned vibecoding up to 11 unleashing the non-technicals in your org to ship vibecode slop straight to prod. it's an idea so obviously terrible to most engineers that maybe it's actually really really smart. much bolder than yet another AI-driven dashboarding tool or smart notebook.

to address the elephant in the room... how do you think about technical debt incurred by users who likely do not understand the underlying data models, consider auth, etc?

rgbrgbon Blackboard System

I built a toy BS with very dumb agents in school in 2012 or so. Multi-agent systems were kind of fringe and retro. It's nuts that modern agents look about the same (basically an OODA loop) but replacing the hand-coded "orient" and "decide" with an LLM is so much easier (for me, a frontier model user) and 100x more capable.

The use-case for multi-agent systems are intuitive from a human perspective (one person can't be an expert in everything) but a little less so with LLM's since, so far, it seems like we use a single frontier model that's pretty good at everything. That said, even a single person has little breakthroughs with different context / sleep / "mind space" so I'd guess there's some useful way to scale that idea usefully with multi-agent systems. I think a lot of these old AI ideas are rich for exploring with LLMs.

what harness do you use with all of these?

rgbrgbon Ghostty is leaving GitHub

>I’ll share more details about where the Ghostty project will be moving to in the coming months. We have a plan but I'm also very much still in discussions with multiple providers (both commercial and FOSS).

what a cliff hanger!

As someone with similar warm feelings for GitHub, it's kind of sad to see the fragmentation but I have similar frustrations with the recent outages. Perhaps it's time to explore the idea of unbundling the social/discovery layer from the code hosting/dev tool so we can live between the myriad git/jj hosts but still do "social coding" together.

rgbrgbon A good AGENTS.md is a model upgrade. A bad one is worse than no docs at all

I'd guess the same has always been true for READMEs / human dev docs. Of course it doesn't transfer directly but still feels incredible to be in an age where we can measure such (previously) theoretical things with synthetic programmers.

rgbrgbon Show HN: OSS Agent I built topped the TerminalBench on Gemini-3-flash-preview

It would be really cool to do a causality investigation to determine which one of these boosts it so much / quantify how much each matters. Who knows, they may all interact in a sum-is-greater-than-parts way that only improves the score when shipped altogether.

rgbrgbon Introducing: ShaderPad

looks great, congrats. quick note, the examples are really cool, but the link in your blogpost is broken.

rgbrgbon Five men control AI. Who should control them?

to be fair, that's exactly what's at issue. controlling AI implies controlling society as intelligence scales.

rgbrgbon Show HN: Anos – a hand-written ~100KiB microkernel for x86-64 and RISC-V

impressive. how do you pronounce it?

rgbrgbon Show HN: Apfel – The free AI already on your Mac

love the simple website and typography. AI design or you? tasteful and fast animations. nice work and thanks for sharing!

rgbrgbon Show HN: Crust – A CLI framework for TypeScript and Bun

Isn't a standalone Bun binary like 50MB because it has to bundle the runtime? How could this get smaller?

rgbrgbon Show HN: Crust – A CLI framework for TypeScript and Bun

nice, congrats on launch. To get an idea... what's the size of a standalone hello world cli binary?

rgbrgbon Show HN: OneCLI – Vault for AI Agents in Rust

It seems that the architecture you describe still gives the key to the agent (who could email it to red team or perform nefarious actions with it). The advantage of OP's architecture is that the agent never sees the key and you could inspect the request before proxying it. Is that right or do I misunderstand something?

rgbrgbon The worst acquisition in history, again

> everyone knows why this purchase was made

you should say what you're talking about because I for one have no idea.

rgbrgbon Show HN: SitDeck – Customizable live dashboard of news, markets, threats

Cool, congrats on shipping. Looks similar to worldmonitor [0][1]. What's the main use-case for this kind of thing? What' the "Watch Floor" you mention?

rgbrgbon Claude Code Remote Control

FWIW I just tried this to monitor / shepherd a PR while I was on the exercise bike and it was pretty seamless. Way easier than the tailscale/vibetunnel thing I got burnt out on last fall.

I was using the Claude app on my iPhone and claude code on a MacBook pro. PR is merged, still on the bike :)

rgbrgbon Claude Code Remote Control

Perhaps, but the key difference is that it’s a developer tool you use from the command line.

rgbrgbon How your high school affects your chances of UC Admission

A lot of commenters seem to think this is purely a DEI thing, but doesn't it match how the best companies hire? Couldn't it be that the colleges are genuinely trying to select who they think will end up at the top of their fields? Common hiring advice for startups (my game) is to look for slope and drive, not deep expertise or experience. The top kid at a bad high school seems like a better bet to me than the median kid from a stellar high school, even if they've done 3x more AP classes. There have been "revelatory" articles like every year for decades about how google doesn't just hire ivy leaguers.

rgbrgbon Ask HN: What Are You Working On? (December 2025)

https://www.hedgy.works/

Helping friends (and friends of friends of friends of friends) find their next startup gig without the application process. Aspiring to be Wealthfront for your career… a passive optimization that pings you every now and then with an interesting interview you could take.

Thinking a lot about how to recognize great matches. I think basically everyone can be talented force multipliers in the right situation / company / mission / team. Everyone here wants to do their life’s work, but it’s hard to find it.

Tactically working to scale reliable human-in-the-loop AI recruiter agents with very few humans.

rgbrgbon Ask HN: How can I get better at using AI for programming?

I use Handy with Claude code. Nice to just have a key combo to transcribe into whatever has focus.

Interesting. Note that the author was a core contributor to jest, metro, yarn and mootools.
