I have been laughing at this entirely too long...

"Advanced Calculus" (Department of Mathematics, Harvard University) is one of the most remarkable advanced mathematics texts I have come across. The book develops vector spaces, differential calculus, differential equations, integration, differentiable manifolds, differential forms, potential theory, and classical mechanics within a unified mathematical framework. What I particularly appreciate is the combination of mathematical rigour and geometric intuition. It serves as an excellent introduction to modern analysis and differential geometry. Definitely worth saving to your bookmarks if you are interested in understanding the mathematical structures underlying advanced calculus. people.math.harvard.edu/~shlomo/docs/A…

IDK I didn't notice any difference, Fable 5 is working just as well as it always has for me

BSIDES #GameOn

back to the 2008 Debian OpenSSL keygen bug!

Maxwell -Boltzmann distribution from beads and a motor.

RSA private keys biased toward 0 bits can be factored by swapping a hard math problem for an easy one: integer factorization becomes polynomial factorization. We found hundreds of real-world keys vulnerable to this. Many traced to a type mismatch in CompleteFTP (now patched): each 32-bit limb got only 8 bits of randomness. We recovered 603 RSA and 74 DSA private keys. blog.trailofbits.com/2026/06/12/fac…

‼️🚨 BREAKING: Nightmare Eclipse just dropped GreatXML, a new BitLocker bypass 0-day vulnerability PoC. He has a new GitHub account. Check it out before it gets deleted again: github.com/MSNightmare

Clearly, Fable is doing a lot of work, and unleashing a ton of agents. To review a short technical note, it released 31 agents, coded simulations to verify my results, did "adversarial reviews". Eventually, it only made the assumptions slightly more rigorous. It is all good. For a four-page technical note+a little code, though, it consumed all my Pro session tokens, *plus* $17 worth of credits. It is ridiculously expensive. I have 20-page reports that are way more complex than this. I can see how Anthropic has entered the phase of market-clearing prices, yield management, and pre-IPO. I recall Boris Cherny saying in a podcast, "run Opus [4.6], not Sonnet. It's worth it". I feel comfortable saying that running your top-shelf model is *not* worth it anymore. Decreasing returns, on most tasks. Like in the real world, some people can be real smart, but real expensive.

Found research from May that shows e. coli "remember" environmental conditions their ancestors lived through and behave differently because of it, all without a brain, neurons, or a nervous system. Inherited proteins handle the memory. The mechanism is what's so cool. Different cellular components relax on different timescales, so the cell integrates its history as a power law instead of a single decay constant. This is an extremely elegant expression of memory as a biochemical hidden state, emergent from ribosome dynamics, that lets a granddaughter cell respond to stress it never personally experienced. It is also oddly close to the logic behind recurrent neural networks. My main takeaways are that memory might predate minds and a growing belief that AI is convergent with biological intelligence. paper: journals.aps.org/prxlife/abstra…

Our statement on the UK government’s demand that all content on all devices sold or used in the country be scanned, on the presumption of nudity, using a dystopian combination of age verification and content scanning. This proposal will not safeguard children. It endangers us all. signal.org/blog/pdfs/2026…

He's training a two layer CNN on MNIST. Set dropout to 0.95. Good, now set the learning rate to 10^-8 and remove all of the 7's from the train set.

AI PCB design vendor apparently threatening @adafruit with CFAA over a reported vuln. I suspect it's not about the vuln. The vendor is raising money; looks like Adafruit was about to post an expose about their marketing claims. See the end of Exhibit K: courtlistener.com/docket/7345024…

Most interesting printer you can build right now. Hello World written across a human hair (56μm). Motion system is driven by M3 threaded rods and some printed parts..

I'm delighted that this short survey, a labor of love, is forthcoming in Notices of the AMS later this month. I'll post a few threads over the next few weeks. Today: why do eigenvectors keep showing up in models of networks and influence?! 1/

Sorry, not sorry. GOBBLES4LYFE That was fun to do

It's the bug of the month for June 2026! CVE-2026-45657 - A CVSS 9.8 vulnerability in Kernel that allows remote, unauthenticated code execution at SYSTEM without user interaction. Yikes!

Some rly interesting RCE bugs got patched today!! Would be an interesting test for a certain super saiyan cyber model that’s really goated at exploitation... Oh well 😔
