Kind of shocked that @gozwift.bsky.social only just worked out how to calculate draft shadows on slopes! I always thought this didn’t seem realistic, particularly downhill. Thanks @zwiftinsider.com! zwiftinsider.com/drafting-upd...

Enjoyable and interesting episode
“Enshittification” is the word of the moment. It’s the reason Google is all ads and Amazon serves you crappy overpriced products. Cory Doctorow, who coined the term, joins @nndroid.bsky.social and @rafaelbehr.bsky.social to discuss how we can combat it ➡️ linktr.ee/ohgodwhatnowpod

📺 Down Cemetery Road had 🎶 Black Steel by Tricky at the end of this week’s episode, which is an awesome track I hadn’t heard in many years. Looking it up I learned it’s a Public Enemy cover. TIL!

I imagine a lot of folks are hurriedly writing system prompts to ignore human-illegible text (too small, not enough contrast, positioned off the screen, obscured by images…)

“Impact: Data exfiltration through prompt injection via multiple vectors like Markdown, tool invocation, etc.”
“Impact: Code execution through prompt injection”
This is fine, they know this happens, don’t worry about it.

Google Antigravity Exfiltrates Data
An indirect prompt injection in an implementation blog can manipulate Antigravity to invoke a malicious browser subagent in order to steal credentials and sensitive code from a user’s IDE.

This post makes a terrific point that the one thing the #opensource community doesn’t seem to want to iterate on is the set of licenses defined as “open source”. And, why no widespread accepted code equivalent of CC-BY-NC?

Anti-fascistic software is made possible by pro-labor licensing.
I've been trying to write this piece for years. Every time I get started I'm just overwhelmed with paralyzing visions of the FOSS commentariat accusing me of WrongThink.
But I'm tired and we urgently need to get our shit together.

WHSmith rebranding to TGJones is ridiculous. I think they were forced to rename after the high street shops but not the travel outlets were sold, but they either should have also licensed the brand, or taken the opportunity to do something different. What the have just looks shoddy and second-rate ☹️
