Author of the blog post here: just for the record, I did try replaying against other models. I replayed from GPT 5.5 to 5.5-mini. It "worked" (replay not rejected) but mini didn't …

They started stockpiling in 2024. The estimate is that they had 1.4 billion barrels by the time the Iran war started, and they're down to 1.2 billion now. (Nobody knows for sure, t…

Oil producer != oil power. What matters is the ability for a government to routinely influence prices. The US government could, in theory, ban all exports or manually dictate produ…

And we’re assuming the reasons given were the real ones. There’s always the possibility of straightforward corruption.

I own a 2018 Model 3 and I love it. Plus it's in good shape with limited maintenance. I'm looking to trade it in. But honestly, I don't want to buy effectively the same car but sli…

"we will provide up to two weeks’ worth of tokens to facilitate your continued operation during the job search. We also partnered with ThriveFlow to furnish, as an option, a collec…

I don't know what a vibe coder is to you, but I expect there are dozens of experienced software developers on HN who are willing to throw a month of work over the course of a year …

I’ve spent the last three days writing an inventory management system for a small store, using Codex and Claude Code. I realize that fully replacing online tools like Shopify is a …

With desalinization, in most places that is the case.

The graveyards are full of blockchain companies who said something similar.

They can't do this at the same margins. Cloud compute traditionally has <= 30% margins, and that's the very generous profit margin that folks like AWS are able to squeeze out of it…

I love "vibes in a trenchcoat" and I don't care if it makes me sound like an LLM.

Subagents are a godsend. Frontier models for initial planning and spec writing, cheaper models for implementing from the spec, frontier models for review. Frontier models to help w…

A lot of this is downstream of compensation schemes that explicitly reward dumb metrics, like raw paper-count without subjective evaluation of contribution or quality. I don't want…

It's a little more complicated than that. If all you're interested in disovery, you can wander off into rabbit holes or disappear into areas that are only interesting to you. Publi…

Wouldn't be bad if the product hadn't been paid for in advance. If it can't be delivered in working form for this car, that's not the end of the world. Tesla can just refund the un…

I paid for a car that drives itself in 2018 and I haven’t received it. Any updates?

I know a number of people who have gone down this route, including Senators. For example, here's Senator Wyden's proposal to add $5 billion in mandatory funding to investigate and …

As a related note: The only way a consumer can get ZDR protections for Claude or OpenAI is to use Amazon Bedrock. But as you say, doesn't work for Fable. I think it even requires a…

We don't need top-end frontier models to write simple applications. Opus works very well for that and it's cheaper. We need them to write things that are at the frontier.

I'm working on cryptography, all from academic research papers. Started well, but it eventually got some word into its context that is on the banlist. I found that if you tell it t…

We improve it by ensuring the same people don't dominate the justice system and that prosecutions still happen whenever they don't. It was Biden's and his AG's job to do something …

What specs do you require for long-distance train electrification vs. the specs you need for electrical delivery to the grid?

Even Star Trek admits that there are horrible events that lie between our world and the utopia.
