FWIW the codex high model has been reliably outperforming claude code for me across several domains if I disable its sandbox (isolate it on its own machine instead). Worth a couple hours experimentation.

This is a very nice blog post because it is not afraid to explain hard work in terms of simple concepts. go.dev/blog/greente...

Filip's analysis is supported by the various attempts I've seen to compare RC generally as a GC algorithm: it uses more CPU time to manage the same amount of memory. It can be more predictable about when the CPU time is used.

Unless you are heavily concurrent, then RC is awful all the time.

Used to: boot cdrom to install OS

Now: visit web site of board management console, insert virtual cdrom from across the network using web serial console, set as primary boot device in bios

Glad we made that easy.

When you're talking to people about developing web sites it is easy to get ground down by constant React talk and accept it as an inevitability. If you ever find yourself here, hop on a plane and try to use GitHub Issues. Esp. if you remember that it used to work, before React.

You can put your prices on your web site. You don't need to make prospects "contact sales" for pricing.

It is surreal flying in a plane equipped with Starlink. I may as well be sitting in the office. Forgot to git clone 2GB of nonsense before getting on the plane? No problem, it runs as fast here as it does in my living room.

iOS 26 has broken half the complications on my watch, with the weather asking me every hour if it is allowed to know my location (and then not telling me the weather).

The Earth still spins. But I am surprised this did not come up in QA?

You can ship a container without a shell in it. There is no law against it. I will sigh quietly.

But if you ship a container with a shell and without the ps command, I will judge you.

Most SQLite databases have a table with a single row for program metadata. You can enforce that there is only one row with:

CREATE TABLE metadata (
id INTEGER PRIMARY KEY CHECK (id = 1), -- one row
...
);
