bluelightning2k··on Show HN: I built a hardware processor that runs Python
I am a pretty smart person. But once in a while I see something like this which reminds me there's always someone far smarter.

Absolutely incredible.

bluelightning2k··on OpenAI looked at buying Cursor creator before turning to Windsurf
Google is famous for cannibalising their own projects or even outright running competing products.
bluelightning2k··on OpenAI looked at buying Cursor creator before turning to Windsurf
They did. This week. The codex cli thing
bluelightning2k··on OpenAI looked at buying Cursor creator before turning to Windsurf
Nice analogy. Although a simpler way to say it is simply vertical integration, a known term for the phenomenon with a whole class of benefits.

One of those benefits brings to mind another analogy: Apple. The ai model and the tooling are kind of like the hardware and software. By co-developing them you can make a better product and certainly something hard to compete with.

bluelightning2k··on Show HN: Zuni (YC S24) – AI Copilot for the Browser
Deeply underwhelming. Your tagline suggests a general "take the wheel" automation. Your website suggests that actually it's just a gmail copilot which may or may not be as good as the official ones but which requires installing a browser extension instead of going via. the approved channels. And there's other specialized website apps to come someday maybe.
bluelightning2k··on Roo or Cline? We're building a superset
Brb just applying to YC with a kilo fork which offers $21 in free usage and solemnly swears not to innovate even harder
bluelightning2k··on Roo or Cline? We're building a superset
The linked article literally starts by calling themselves an anti innovation company and declaring they do not intend to improve on it (at least not in innovative ways)
bluelightning2k··on Roo or Cline? We're building a superset
I do not respect this project. "We are stealing and adding no value" is not a good pitch, borders on anti open source, and just fundamentally why would anyone support you or choose you over the original(s).
bluelightning2k··on Show HN: Hatchet v1 – A task orchestration platform built on Postgres
Is this Python only?

More importantly: can this be used to run untrusted jobs? E.g. user-supplied or AI supplied code?

bluelightning2k··on Building a modern durable execution engine from first principles
I find this type of thing very interesting technically, but not very interesting commercially.

It would seem to me that durable execution implies long running jobs, but this kind of work suggests micro optimisation of a couple of ms. The applications inherently don't care about this stuff?

What am I missing. Or is it just that at a big enough scale anything matters.

bluelightning2k··on We hacked Gemini's Python sandbox and leaked its source code (at least some)
Cool write up. Although it's not exactly a huge vulnerability. I guess it says a lot about how security conscious Google is that they consider this to be significant. (You did mention that you knew the company's specific policy considered this highly confidential so it does count but it feels a little more like "technically considered a vulnerability" rather than clearly one.)
bluelightning2k··on Launch HN: Continue (YC S23) – Create custom AI code assistants
How is this customisation not equivalent to just a cursor or windsurf rules file?
bluelightning2k··on Kilo Code: Speedrunning open source coding AI
I usually support everything but isn't this literally just "we are trying to fork roo code and pay $15 of your tokens so we can show VCs that we have users" - as in people like free money. But that wouldn't be enough of a bribe to justify using the fork over the real project for me at least
bluelightning2k··on Show HN: AgentKit – JavaScript Alternative to OpenAI Agents SDK with Native MCP
This looks really good. I'm going to take a detailed look at this for sure. Thanks!
bluelightning2k··on Tell HN: Windsurf edits are failing and burning infinite credits for most users
I think we as a community should seriously call out companies when they have a status page and refuse to update it to reflect outages just to cheat on their uptime stats
bluelightning2k··on Show HN: Ariana – A time travel debugger for PY/JS right in VSCode
This is very, very, very cool.

I implemented something like this once but had to use the typescript compiler to identify all the variable names and also use the typescript compiler to find valid moments they could change and insert code to capture their value at that time. Guessing you didn't go to that length in multiple languages. Sou how did you manage this? I'd be very interested in a technical write up and I suspect hn would too

bluelightning2k··on Show HN: Time travel debugging AI for more reliable vibe coding
You say it's called Nut because it's about cracking nuts. Wouldn't a truer reason be it's a play on bolt? (Nuts and bolts)

I'd be interested to read a blog post or technical write up. I think conceptually it's an interesting idea

bluelightning2k··on How the Boeing 737 MAX Disaster Looks to a Software Developer (2019)
Good write up. Interesting pov
bluelightning2k··on When your last name is Null, nothing works
An ironic thought: if it became too cumbersome and you decided to change your name but the name change system has the same issue.
bluelightning2k··on Debugging an Undebuggable App
Or maybe trying to prove copyright theft, if the app itself was recompiled with different logos etc
bluelightning2k··on Debugging an Undebuggable App
Great write up. I'm very curious whether this was a legitimate app which was unreasonably paranoid, or if it turns out he was debugging it in the first place because it was accused of being malware.

Seems like a lot of effort to go to otherwise

bluelightning2k··on Library Sandboxing for Verona
Given this says it's potentially useful beyond Verona does this make it equivalent to gvisor/firecracker? Although why not use firecracker itself as it's so extensively battle tested
bluelightning2k··on TL;DR of Deep Dive into LLMs Like ChatGPT by Andrej Karpathy
Great write up of what is presumably a truly great lecture. Debating trying to follow the original now.
bluelightning2k··on TypeScript enums: use cases and alternatives
I personally see TS enums as an anti-pattern.

One big reason: you can't name it interfaces.d.ts, or import as type, which has widespread implications:

Your types are now affecting your shipped bundles.

Sure that's a small bit of size - but it can actually lead to things like server side code getting shipped to the client.

Whereas if it's all .d.ts stuff you know there's no risk of chained dependencies.

I'd go so far as to say default eslint rules should disallow enums.

bluelightning2k··on Why does Cloudflare Pages have such a generous free tier?
As hardware gets cheaper, and economies of scale get bigger, it's way way cheaper to provide free stuff than spend on sales and marketing.

Works best at the extremes

bluelightning2k··on Best Pens for 2025
How does a generic "best pens" listicle which recommends the company's own pen make it near the top of HN without manipulation ?
bluelightning2k··on Show HN: Stagehand – an open source browser automation framework powered by AI
Does this open up the possibility of automating an existing open browser tab? (Instead of a headless or specifically opened instance of chrome?)
bluelightning2k··on GPT-5 is behind schedule
There's at least 4 major releases just in GPT4.

GPT4, GPT4T, Gpt4o-Mini, GPT4o,

bluelightning2k··on Gemini 2.0: our new AI model for the agentic era
Does anyone know how to sign up to the speech output wait list or tester program? I have a decent spent with GCP over the years if that helps at all. Really want DemoTime videos to use those voices. (I like how truly incredible best in the world tts is like a footnote in this larger announcement.)
