They aren't really separate applications, though. More importantly, that's not the primary effort (and cost) driver for this effort estimation model. I used the COCOMO model, an effort estimation model that was publicly available

in fact, operating systems kernels are known to be more difficult to develop than typical applications. I'm not convinced. The core OS kernel code, sure; but more than half of the Linux kernel is drivers, and those are not just appl

It's entirely reasonable for the USG to say "we don't want to use a product with guardrails". Plenty of people have gotten annoyed with Fable and done exactly that! But to prohibit anyone else from using it is a much

unseasonal April fools joke Not at all. Route 53 Files is a completely real service.

Oh, I assumed that "style guide" meant things like starting launch posts with "I'm excited to announce", providing a simple demonstration of how to use the service, including screenshots, including a customer quote

Yeah, I was aware of those... but I just couldn't bring myself to write American, especially in the current political climate. You can consider those a non-tariff trade barrier.

Oh, I was being facetious. I'm pretty sure Jeff mentioned needing to spend time writing a style guide when he started having other Amazonians write posts for "his" blog. As a non-Amazonian I've never seen it, of course.

Wait, there's an official style guide? (In all seriousness, I've been reading AWS launch posts for 20 years; this one was mainly imitating the S3 Files launch post but I diverged by adding the customer quote and the FAQ -- because

Files which aren't DNS keys get ignored by Route 53 Files. So you could absolutely have a git checkout and update your DNS with 'git pull'.

There are apparently many people managing their S3 Objects by hand but long to have them in a file system, yes.

But does America have a trade imbalance with Canada? Yes, because Canada has a lot of cheap oil which America wants. If you deduct oil, the trade deficit runs the other way.

The oath isn't legally binding, but the law is. Committing war crimes is illegal even if the civilian government orders it.

Typo in the post: "SQL 3.51.2" should presumably be "SQLite 3.51.2".

A counterexample of the form "X cycles to X after N steps" is easy to check. A counterexample of the form "starting with X we keep going up forever" is hard to check in finite time.

You're right, I was remembering the peak and duration of the railway boom but of course it wasn't at the peak for the entire duration.

Yes. In inflation adjusted dollars spending on AI dwarfs previous "megaprojects". But as a fraction of GDP it's fairly modest -- comparable to the Apollo Project. It's a sign of how much the economy has grown that

I've seen plenty of people saying "Mythos isn't all that exceptional, lots of LLMs can find security vulnerabilities" -- and indeed there is some evidence for that; it sounds like Anthropic was taken somewhat by surprise

This is hardly news? We've known for months that a flood of AI-assisted vulnerabilities was coming; I posted on Twitter in March calling 2026 the year of a million CVEs: https://x.com/i/status/203504557311678

Frankly, there's no way any arch venue at the time would have done anything beyond rejecting it with "caches make RSA fast, what's the problem?" Security wasn't something CPU designers paid much attention to, and cr
