AI solves ancient cipher & Google ad reviews questioned - Hacker News (Sep 14, 2026)

A 370-year-old cipher that stumped people for centuries may have been cracked by an AI model in under an hour. Welcome to The Automated Daily, hacker news edition. The podcast created by generative AI. It’s September 14th, 2026, and today we’ve got a sharp mix of AI, privacy, programming languages, web standards, and a messy leadership turn in the WordPress world.

AI solves ancient cipher

We’ll start with that AI puzzle story, because it’s the one most likely to make historians and model builders stop and stare. Vals AI reports that Claude Fable 5.1 solved Sir Thomas Urquhart’s Cyphral Distich, a 17th-century cipher that had resisted earlier attempts. The key insight was apparently simple in hindsight: the numbers pointed back into the book itself, not to some outside code table. The decoded message turned out to be a royalist prayer supporting King Charles the Second. If the report holds up, the real significance is not just one solved riddle. It’s that frontier models may now be genuinely useful for slow, obscure research problems that used to require a lot of patient human effort.

Google ad reviews questioned

Staying with AI, but in a much less romantic setting, there’s a pointed critique of Google’s ad moderation. The complaint is that deceptive ads designed to look like iPhone system alerts are still being approved inside YouTube, even after users report them. What makes the story sting is that the author says Google’s own Gemini model immediately recognized the ad as misleading and something that should be rejected. So the gap here is not whether the problem is detectable. It seems to be whether Google’s enforcement process is actually acting on it. That matters because ad scams scale fast, and trust in a platform drops quickly when the fake stuff is easier for AI to spot than for the company to remove.

Signal moves beyond numbers

On the privacy front, Signal appears to be moving closer to accounts that don’t depend on phone numbers. The discussion centers on recent Android commits that suggest numberless registration and login are actively being built. That’s a meaningful shift for a service that has long tied identity to a phone number, even while trying to minimize what that number reveals. The open questions are exactly the ones you’d expect: how do you preserve privacy, how do you recover accounts, and how do you stop spammers from exploiting easier signup paths? The big takeaway is that this no longer looks like a vague idea. It looks like work in progress, and potentially one of Signal’s biggest account-model changes in years.

Julia 1.13 boosts speed

For developers, Julia 1.13 is out, and this looks like the kind of release people actually feel in daily use. The headline improvements are lower latency, faster package precompilation, quicker startup, and a nicer REPL with built-in syntax highlighting and better history search. There are also under-the-hood gains around scheduling, interrupt handling, and garbage collection, which means fewer rough edges when workloads get busy or when you just need Ctrl-C to behave. None of that is flashy, but it matters. Languages win loyalty when they become more predictable and less frustrating, and this release seems aimed squarely at that practical experience.

JPEG XL web fight

There’s also a lively standards debate around JPEG XL. A new piece argues that while the format is technically impressive, it still doesn’t make much sense as a browser image codec. The author’s case is that its strongest advantages are either too niche or no longer strong enough compared with AVIF and WebP, especially once you factor in decode cost, implementation complexity, and web performance priorities. This is one of those classic engineering arguments where being good is not the same as being the right fit. For the web, the question isn’t just image quality. It’s whether another format meaningfully improves the everyday tradeoff between speed, simplicity, and compatibility.

Automattic leadership snaps back

And finally, a leadership story with wider implications for the web publishing world. Automattic has confirmed that Matt Mullenweg is back as chairman and CEO after what sounds like a very messy internal struggle. Reports say the board had placed him on leave and named an interim chief executive, only for Mullenweg to signal internally that the issue was resolved and that he was back in charge. That kind of reversal is notable on its own, but it matters more because Automattic and WordPress sit in a huge part of the internet’s publishing infrastructure. When governance gets murky at a company like that, people naturally wonder what it means for product direction, partnerships, and stability across the ecosystem.

That’s the roundup for today: AI taking on historical ciphers, Signal pushing toward more private accounts, Julia getting faster, fresh criticism of Google’s ad enforcement, a renewed browser format fight, and another twist at Automattic. Links to all stories are in the episode notes. Thanks for listening.
