A few weeks ago I fixed a bug in #OpenZFS and I can't stop thinking about it.

An (almost) catastrophic OpenZFS bug and the humans that made it (and Rust is here too)

A couple of weeks ago I fixed a nasty bug in this function in OpenZFS:

I’ve created an RFC to re-license #PHP under the Modified BSD License (BSD-3-Clause).

Please spread this far and wide. Discussion is open for 6 months so everyone can voice concerns or ask questions.

php.internals: [RFC] Updating the PHP License

“When developers are allowed to use AI tools, they take 19% longer to complete issues—a significant slowdown that goes against developer beliefs and expert forecasts. This gap between perception and reality is striking: developers expected AI to speed them up by 24%, and even after experiencing the slowdown, they still believed AI had sped them up by 20%.” https://metr.org/blog/2025-07-10-early-2025-ai-experienced-os-dev-study/

The #homeautomation protocol is named #Thread, perhaps that is a typo as #Threat is more apt and accurate. If you roll your own device you might very well experience the full force of their blood thirsty lawyers.

@ramsey massive! I can’t imagine the behind the scenes work needed for this <3

HUGE new RFC in PHP-land: Updating the somewhat messy and slightly unwieldy PHP license to BSD 3-clause.

Addendum: It's also wild how project planning does not seem to take into account the psychic damage that the team will incur in doing it. Like, how does no one factor the morale of the engineering team into these things? Engineers don't even get shot for desertion, they get raises at another companies for leaving, the current system isn't even rational on the grounds of capitalism.
