This morning I spent some time debugging an app which logs as if it's AD 57203, to wit
{"level":20,"time":1742987150412,"pid":1, ...
$ date -r 1742987150412
Fri Jan 24 10:20:12 CET 57203
but it turns out the other instance (the one that works, as in the user is able to download files from there) has roughly the same time internally, so *that* was not its main problem.
Mind boggled, debugging to continue until *something* improves.

Time for another episode of the core․py podcast!
Are we finally covering the long-awaited topic of garbage collection? Well, no. Pablo wanted to talk about his latest PEP 768 instead. And it's indeed an interesting deep dive into how debuggers work.
We also argue about syntax highlighting in PyREPL and resolve the bet around reference counting from Episode 18!
Spotify for CreatorsEpisode 20: Remote Code Execution By Design by core.pyIn this episode, Pablo's avoiding the topic of garbage collection by talking about his latest PEP, which allows unprecedented interaction with a running Python process. We also resolve the bet about reference counting semantics, mention some notable changes in Python since the last episode, and discuss syntax highlighting in PyREPL and why it's bad, actually.## Timestamps(00:00:00) INTRO(00:02:16) PART 1: PABLO'S LATEST PEP(00:04:34) gdb is IMPOSSIBLE(00:12:49) Make the process run code for you(00:14:14) This already works on PyPy(00:15:13) How does it work?(00:25:38) Why a file?(00:31:15) What if you don't trust Pablo?(00:32:57) sys.remote_exec()(00:36:09) Less obvious use cases(00:46:56) PART 2: BETS(00:55:44) PART 3: PR OF THE WEEK(00:55:50) Łukasz: syntax highlighting in PyREPL(01:10:14) Pablo's PR: allow the parser to activate future imports on the fly(01:20:11) PART 4: WHAT'S GOING ON IN CPYTHON(01:20:22) Free threading(01:23:30) Performance(01:34:41) PEP 765 implemented(01:36:08) concurrent.futures.Executor.map(buffersize=)(01:36:57) io.Reader and io.Writer(01:38:40) Pabluco's linecache fetching interactive source code(01:41:25) ast.unparse() roundtrip with semicolons(01:41:59) OUTRO

It's a #debugging day today and thus I'm talking to myself a lot. Thankfully, the people I share my office with are busy in the lab.
