Honestly the only good use of Leto I’ve seen in what has proven to be an astoundingly durable career. Consistently the worst part of everything he does, yet somehow continues to work. And that docu-drama was so good I still think of it every time I use the WeWork in Glendale.

Hi Alexander! I’m afraid my pinned joke may have given you the wrong idea about my identity; the last bit about “with a different face for some reason” is more or less a “/s” tone indicator. I’m a different software engineer with the same name. :) people love that guy’s work though!

Never actually played the game, but I’ve been getting email for that guy since I was in 5th grade… people love his work, I know that for sure

I was floored by the AirPods translate functionality… wonder how well it works outside of marketing material? Felt very Star Trek as advertised

Oh yeah, have a blast, love the chatbot as a chatbot, I was more referring to coders writing auth systems using agents and expecting them to pass any kind of audit

I wonder if maybe Cracker Barrel is to Christmas trends what Milan is to fashion trends. Maybe all the grandparents go to Cracker Barrel on Sep 1st like designers go to Italy in 2025 for what they’re gonna sell at Target in 2026.

So I lost a day of focus and productivity at work calling every pharmacy in town; no one will pay for that but me. Oh well.

Not as frustrating as some have it… and I’m far from the first to say it. but: I’m not a fan of the current system. We should improve society somewhat.

Imagining leading a new employee orientation, but all of the employees are bots who keep telling me what a good job I’m doing… while completely failing to grasp anything else I’ve said

(which tbf is not that different from regular human onboarding)

Split your format and lint jobs so they can run in parallel, independently of your test and build jobs

And the presets idea is intriguing, sounds like a great way to add versatility out of the box!

We were thinking through dependency configs specifically… we have lots of internal, interdependent packages, but if a dev removes a crate and doesn’t update the config, we get an error in CI.

Here’s a sample repo that can generate a config, still pondering when to run github.com/johncarmack1...

Jacob! I'm so glad you posted this, it's how I found your profile! We use covector at our company (www.flightscience.ai) and I love it! Releases & PRs are so fast and convenient.

Was wondering today: do you know of any projects that have successfully automated creation/maintenance of config.json?
