Quoting Kyle Daigle

[GitHub] platform activity is surging. There were 1 billion commits in 2025. Now, it's 275 million per week, on pace for 14 billion this year if growth remains linear (spoiler: it won't.)

GitHub Actions has grown from 500M minutes/week in 2023 to 1B minutes/week in 2025, and now 2.1B minutes so far this week.

The cognitive impact of coding agents

A fun thing about recording a podcast with a professional like Lenny Rachitsky is that his team know how to slice the resulting video up into TikTok-sized short form vertical videos. Here's one he shared on Twitter today which ended up attracting over 1.1m views!

That was 48 seconds. Our full conversation lasted 1 hour 40 minutes.

🎬 Frankie Freako

letterboxd.com/danielpietzsch/film/frankie-freako/

Movie poster for “Frankie Freako”.

After the very positive surprise of Psycho Goreman, this is the second movie from the same director. Unfortunately, this is not even close to the quality of PG. The humour is lame and just silly (well, yes, some things were indeed pretty funny, but that was an exception), the characters are not as likeable and the puppets are not that great either. I’d rather watch PG again!

Quoting Willy Tarreau

On the kernel security list we've seen a huge bump of reports. We were between 2 and 3 per week maybe two years ago, then reached probably 10 a week over the last year with the only difference being only AI slop, and now since the beginning of the year we're around 5-10 per day depending on the days (fridays and tuesdays seem the worst). Now most of these reports are correct, to the point that we had to bring in more maintainers to help us.

And we're now seeing on a daily basis something that never happened before: duplicate reports, or the same bug found by two different people using (possibly slightly) different tools.

Quoting Daniel Stenberg

The challenge with AI in open source security has transitioned from an AI slop tsunami into more of a ... plain security report tsunami. Less slop but lots of reports. Many of them really good.

I'm spending hours per day on this now. It's intense.

Quoting Greg Kroah-Hartman

Months ago, we were getting what we called 'AI slop,' AI-generated security reports that were obviously wrong or low quality. It was kind of funny. It didn't really worry us.

Something happened a month ago, and the world switched. Now we have real reports. All open source projects have real reports that are made with AI, but they're good, and they're real.

— Greg Kroah-Hartman, Linux kernel maintainer (bio), in conversation with Steven J. Vaughan-Nichols

Apple Releases iOS 18 Security Updates for iOS 26 Holdouts

Rosalía Berghain Live

I thought the official video of Berghain by Rosalía (feat. Björk & Yves Tumor) was great — “I don’t even know what this is — classical pop? surrealist orchestral?” — and this recent live performance from the Brit Awards takes the song to the next level. I loved it. (via kenzie)

Apple Still Has Jessica Chastain’s ‘The Savant’ on Ice, Seven Months After It Was Set to Debut

macstories.net/news/coming-soon-whats-next-on-apple-tv-and-apple-arcade-in-april-2026/

John Voorhees, at MacStories:

It’s a new month and you know what that means: time for a roundup of everything coming to Apple TV and Apple Arcade for April 2026.

What’s still not coming: Jessica Chastain’s political thriller The Savant, originally set for September, but rescheduled for “at a later date” out of cowardice.

Apple’s “at a later date” is looking more and more like Trump’s “in two weeks”.

Can JavaScript Escape a CSP Meta Tag Inside an Iframe?

Research: Can JavaScript Escape a CSP Meta Tag Inside an Iframe?

In trying to build my own version of Claude Artifacts I got curious about options for applying CSP headers to content in sandboxed iframes without using a separate domain to host the files. Turns out you can inject <meta http-equiv="Content-Security-Policy"...> tags at the top of the iframe content and they'll be obeyed even if subsequent untrusted JavaScript tries to manipulate them.

This Is Us

The commander of NASA’s Artemis II mission to the Moon, Reid Wiseman, took this photo of the Earth as the spacecraft speeds away our planet.

There are two auroras (top right and bottom left) and zodiacal light (bottom right) is visible as the Earth eclipses the Sun.

That is so cool. Worth clicking through to see the high-resolution image.
