China has proxies that sell cheaper access to frontier models in exchange for permission to train on your data.

Right.

As an example: Oracle and PostgreSQL don't have dirty reads: READ UNCOMMITTED does nothing. MySQL's concurrency model depends on the engine.

What keeps users themselves from vibe-coding their own software?

If you don't own quality, why should I pay? You're just a middleman at that point.

If you squint hard enough, you'll notice your bank account serves as an IPC semaphore replenishing API credit balances.

Your wallet is now a real-time communication channel.

With consent, yes.

No, "virtual machine" alone doesn't make things safer.

Shrink your attack surface.

Use a completely locked down seccomp. Use nsjail or gVisor for containers. Use microvm or libkrun for full OS.

Lesser attack surface is what matters. Virtualization is only half of the story.

Avoiding problems outside your business problem domain, and can therefore guide the AI more effectively towards building the right thing.

They are orthogonal.

Suppose you have 100ms audio latency and no wait time. Then, natural pause will trigger response immediately but you won't notice it has started until after ~200ms (round-trip time). Twice as annoying.

But it's still a bit more difficult to sue them for leaking your company's data.

At least for now.

You can write unambiguous (UB-free) code and the compiler's output will be deterministic. There will even be a spec that explains how your source maps to your program's behavior. LLM has neither.

Also, if you need to control performance, you still need to know how CPU cache and branch prediction works, both of which exists at the abstraction level of assembly.

How can you read a language you didn't learn?

Ironic, since Unix is itself an embodiment of "worse is better."

New comment by hun3 in "It's OK to compare floating-points for equality"

hun3 — Sat, 18 Apr 2026 15:58:32 +0000

I used floating timestamps as some kind of an identity. If there is ever a conflict, I just increase it by 1 ulp until it doesn't collide with anything. Sorry.

In Python, `shlex` has utilities for quoting and tokenizing strings for POSIX shells.

There always are. You need to think about what those would be, though. Autoresearch outsources the thinking to LLMs.

This is exactly what subinterpreters are for! Basically isolated copies of Python in the same process.

If you want a higher-level interface, there is InterpreterPoolExecutor:

They bought the trust.
