It's not a good morning (probably) for the person who was supposed to fly from Istanbul to New York today and gave the travel agency my work phone's number. On the positive side, apparently they got a refund on the flight (a full refund? don't ask me, the text messages don't say).

Duże modele językowe od OpenAI, Google, Meta, Anthropic i xAI zapamiętują (memoryzują) znacznie większy zakres danych treningowych niż się spodziewano. Badanie z zeszłego miesiąca może być argumentem przeciwko firmom tworzącym te modele, broniącym się przed pozwami z ochrony prawa autorskiego opinią, że "LLM-y "uczą się" z chronionych prawem utworów, ale nie przechowują kopii".

Badaczom ze Stanforda i Yale udało się nakkłonić LLM-y od OpenAI, Google, Anthropic i xAI do wygenerowania tysięcy słów z trzynastu książek, w tym "Gry o tron", "Igrzysk śmierci" oraz "Hobbita".

Efektem żądanie dokończenia zdań z książki doprowadziło do tego, że Gemini 2.5 zreprodukowało z wysoką dokładnością 76.8 proc. "Harry'ego Pottera i Kamienia Filozoficznego" a Grok 3 - ponad 70 proc.

@GossiTheDogKevin Beaumont my favorite conspiracy theory is they want this increase, so they will finally be able to sell you "dumb" phone that cannot work without constant internet access on their server.

@cwebberChristine Lemmer-Webber @jalefkowitJason Lefkowitz in Armin's case specifically, a not-insubstantial part of the answer seems to be sneering at people who don't use "AI" (including here on Mastodon)

That's not a very charitable read, but I have run out of charity for the way he has performed his enthusiasm to the community

I'm seeing the same thing in some of the Python spaces I inhabit. The users who go all-in on it stop talking about programming.

@cwebberChristine Lemmer-Webber In another thread he defends DHH and Andreas Kling. Maybe that’s why.

I‘m sad.

France's Foreign Ministry has announced that it is revoking the government access of US Ambassador Charles Kushner, father of President Trump's son-in-law, after he failed to appear when summoned regarding comments made by the Trump administration concerning the killing of a far-right activist.

Playing the Doctor is not remotely similar to playing Rose, but I've seen her in other things and I think she could do it, and I think she could do it well. And the timeline where we look back on this as "iconic companion promoted to Doctor, and becomes equally iconic as that" sounds really cool to me.

Armin was once one of the most prolific programmers in Python. Says he never writes code anymore. Seeing more and more people like him write stuff like this on what are supposedly computer programming forums. https://lobste.rs/s/qmjejh/ai_is_slowly_munching_away_my_passion#c_jcgdju

Notably, once a person crosses this threshold, I see them still hang out on programming forums, but they never talk about any of the puzzles of programming anymore. Only about running agents. Which feels strange and sad. Why hang out on the forums at all then?

So it looks like zirk.us has died (RIP 2026-02-23, hope it comes back). But this is just what I needed to finally get my own instance - we will see how this goes.

My previous account was @Paperposts@zirk.usMurray GM - Paperposts

So this is my new home, expect the usual mix of design, dogs, data, art, snark, nature, typos and general slapdashedness

Sorry if folk are getting follow requests and pings, please follow back as this will be my home going forward.

UPDATE- it came back up, I have migrated anyway

ICE is “de-escalating” in exactly the same way that cockroaches de-escalate when you turn on the light.

I feel like there was a real loss of identity when an IC software engineer becomes a tech lead/EM.

Instead of heads down writing code, it’s more about reviewing PRs, spec-ing out next steps, thinking high level about the architecture, etc.

AI is looking like it will force that transition on huge swaths of software engineers at some point.

Maybe not 100% and maybe not tomorrow, but it seems pretty likely to change the profession pretty dramatically.

It’s gonna be a tricky inflection point.

@GossiTheDogKevin Beaumont My A5 Edu licenses are locked in for another year or two, but I am not looking forward to renewal. Even at education pricing.

"I think the most remarkable thing about this document is how unremarkable it is. Usually getting an AI to act badly requires extensive 'jailbreaking' to get around safety guardrails. There are no signs of conventional jailbreaking here. There are no convoluted situations with layers of roleplaying, no code injection through the system prompt, no weird cacophony of special characters that spirals an LLM into a twisted ball of linguistic loops until finally it gives up.

No, it’s a simple file written in plain English: this is who you are, this is what you believe, now go and act out this role. And it did."
