This man just took the same plastic recorder that used to sound like a dying goose in elementary school and casually started shredding Sultans of Swing on it. Eyes half-closed, fully committed, fingers flying like he actually practiced this instead of just surviving Hot Cross Buns. Somewhere a music teacher is watching this and having an existential crisis. The recorder has seen things. It will never be the same.

Hooray the long dry boring years of no new attacks on sha256 are over! (All 12 of them.)
SHA-256 is not broken, but its security margin lost 1 more round this year: Last week I found a collision attack on reduced 39-round that improves prior art by over 30 bits and the first differential attack on that round better than generic search on @yukonresearch Hashsmash board. The attack rests on the same method as prior art ePrint 2026/1120 with new insights that first 2 state words could remain free, allowing a critical condition at step 16 rebuilt as a claw-search problem rather than a probabilistic filter. Took days of watching SAT logs, burning cores and arguing with Claude on what's possible to get a result close to generic search. Since my initial submission, other hashsmash participants sraiw, @cyberaxe, @privacymage, @lamb356_ and @geeknik pushed it down by over 6.5 bits, currently estimated at 118.15 bits. The tree of submissions is hard to follow, so I put the construction, insights and numbers into a blog and am working on detailed technical report. It's fascinating to see an initial structural observation develop into an improvement in the reduced-round collision frontier within days. AI is now a real aid in cryptanalysis and open collaboration speeds it up.

I suspect the real reason eMudhra is exiting the SSL business is Google indicated it is most likely going to drop eMudhra from being trusted by Chrome AT ALL, after observing inexplicable incompetence in how they mis-generated their private key for the CA certificate.
BREAKING: eMudhra exits SSL/TLS certificate business, blames social media instead of incompetence for the same

story time! 🐉 this is the tale of a lazily crafted one-shot cron job prompt that resulted in autonomous solutions for uncracked codebreaking challenges, more efficient ways of multiplying matrices, and a new computer-verified bound on a number theory problem that's been open since 1932. so last week, i had a $200 claude account sitting around that had just gotten a full weekly reset. i hate wasting tokens. the labs have been knocking out unsolved problems left and right lately, and i caught myself thinking… why not give it a shot? so i sent claude this prompt, typos and all: "can you wraite a promtp for a cron job that can run every day thajt will try to find solutions to unsolved ciphers or transltions or math problems or theormes or things of that nature!! every day a new attempt as hard as possible all day without giving ujp and with maximum ceraitvityy, resourcesleflses, andpersticense! dont worry about token spend! and dont forget a bit all caps lots of emojis celebration to notify the uers if we get any intersting or sucsfful confirmd reulsts!!" yes, admittedly not my best work 😆 but Opus-5.5 ran with the ball and turned that one sloppy sentence into "THE DAILY ORACLE 🔮" it's a swarm of Fable + Opus agents that clocks in every morning at 4:20 (obviously), builds and maintains its own hit list of well over a hundred of humanity's unsolved problems, and then goes full send on a handful of them every shift. ciphers nobody has broken, scripts nobody can read, conjectures nobody has proven, record tables nobody has beaten. and there's one rule above all the others: nothing counts until skeptic agents, each starting from a fresh context and writing their own code, rebuild the result from scratch and sign off on it. if any of them can't reproduce it, can't confirm it's new, or thinks we stretched the definition of "solved," it doesn't count. day 1, the legion picked its own target: J.-F. Bouchaudy's cipher-machine challenges. these are simulations of real vintage machines (Hebern rotor machines, the Kryha, Lorenz, SIGABA), with problems that had been sitting on his solver tables with no solver for months or years. on the morning of day 2, i was half asleep when my laptop suddenly says, in a robot voice: "Breakthrough. The Daily Oracle has a confirmed solution." 👁️👄👁️ i was startled. then the ALL CAPS emoji flood hits my screen. Hebern 5-rotor Problem 8 🔓 then Kryha v2 Problem 5 🔓 i emailed the author, Jean-François Bouchaudy, a French cryptography enthusiast who builds these machine simulators and challenges as a labor of love (he told me he started out programming on punch cards 🥹). he checked both solutions and put my name on his solver tables as the first and only solver 🫡 for context: his tables are a who's who of serious classical codebreakers. they'd cleared the sibling problems on these same machines, but nobody had cracked these two. in his words: "two of my most complex problems—ones that no other expert had managed to solve… I knew AI would eventually be applied to classical cryptography, but I thought I would have to wait years to see it happen." he ended his email with: "I offer my congratulations in the Japanese manner: with a deep, respectful bow." 🙇 honestly one of the most wholesome emails i've ever received and then, over the next few days, more started landing 🧮 📐 graph theory: 7 explicit graphs bigger than the current entries in the degree-diameter table, which asks how big a network can get when every node has limited connections and every pair is only a few hops apart. the biggest jump is 13,365 vertices vs the table's 11,785, a +13.4% improvement. 🔢 number theory: Lehmer's totient problem has been open since 1932. we pushed the bound so that any counterexample now has to be bigger than 10^50. the previous certified bound was 10^26. the problem itself is still open, but the lower bound just jumped 24 orders of magnitude. ⚡ matrix multiplication: this is the operation underneath basically all of modern AI compute. the legion found schemes that use fewer multiplications than the public catalogues we checked for several matrix shapes, like ⟨15,16,16⟩ in 2,180 multiplications vs the best known 2,223. these build on LITA's square schemes, and we credit them by name. 📡 coding theory: 30 error-correcting codes bigger than the best known entries in A. E. Brouwer's tables. 🛡️ AI safety benchmarks: we found counterexamples for 2 neural-network verification instances from VNN-COMP 2026 that no participating tool resolved within the competition time limit, and pushed a defended RobustBench model below its listed robustness score. small dents, but real ones. the bloopers are part of the story too: — at one point, some agents snuck past a website's bot filter to check a record table. we retracted every result that depended on it. no evasion, no celebration. — two of our records got beaten by a human contributor before we could even publish them. the frontier moves FAST. now as is customary around here, time to share the magic! so… without further ado…

Google how many orgs have made, and do make, $1 trillion in profit every year to see why I'm saying the things that I am. For context there are only 16 organizations which are valued at a trillion dollars or more. But that is not the same as profit. That's just what they are worth on paper.
AI has a $6 trillion problem. The global AI industry needs to earn $6 trillion a year by 2031 to justify the data centers being built today, per Bain. They say that existing AI products like chatbots and coding tools may bring in $1.8 trillion at most.

The so-called first AI to "pass the video Turing test" just miserably failed each one of my extremely simple Turing tests.
Introducing Griffin, the first model to pass the video Turing test. 48% of people who talked to it live thought it was a real human. Previous systems have had a pass rate <3%. It is #1 on NVIDIA's benchmark for full-duplex AI video. It’s the first Human Interaction Model (HIM).
Readers added context they thought people might want to know
The 48% figure and "video Turing test" claim are from Tavus's own study of 54 one-minute calls, not independently verified or using a standard protocol. Griffin-Lite leads NVIDIA's VideoFDB benchmark on their public leaderboard. cellcog.ai/blog/tavus-gri… research.nvidia.com/labs/amri/proj… tech-ish.com/2026/10/02/tav…

In this era of artificial intelligence, it is becoming urgent to distinguish human art from what machines produce. There is an ontological difference, even before an aesthetic one, between art and what a machine can generate through statistical calculation based on millions of images created by others. Algorithms lack the spark of humanity. For this reason, the Church wishes to renew an alliance with artists and cultural institutions to safeguard our humanity.

Rust has one serialization library that is Serde. Over the years I collected a bucket list of all the things that I do not enjoy about it. Finally did something about it and finished Deser. Here is a small summary of the why, what and how: lucumr.pocoo.org/2026/9/29/d…

Someone rewrote Kafka in Rust and embedded it in Postgres using pgrx 🤯 Kafgres is a Rust-based Kafka broker that runs within Postgres. Kafka clients connect to Postgres on port 9092 and literally can't tell the difference. 🧵
