You’re very welcome!
Fooled you, Daylight Savings Time! The hour you took from me last night was actually the hour I took when I fled Eastern Time the night before!

Not sure what phase of my life I’m in, but here’s that modelling balloon icosidodecahedron nobody asked for!
In theory it could be made out of a single modelling balloon, although in reality they don’t make balloons long enough :(

Think your burner number keeps you anonymous? Kang et al. reveal a severe privacy threat, a cross-platform linking attack targeting messaging apps. Using contact discovery and SSO, it deanonymizes users and pinpoints their physical locations.
Today I was looking at an article on Multi-Party Threshold #Cryptography and wondered why "threshold" has only one h. Turns out the etymology is not "thresh-hold" at all, but "thresh-wold", possibly from the Middle English word "wold" meaning "forest". Mind blown.
For my next book, I’m reading some mid-20th century papers on color vision. These guys will go on for pages about the kind of filters they use, and then their discussion of the test subjects will be “we took the measurements on Mr. Perley G. Nutting, Jr., who sat still for a really long time.”
Love that paper!
At 26, during the Reign of Terror in France, Jean-Baptiste Joseph Fourier narrowly avoided the guillotine. A decade later, he made a discovery that changed mathematics forever.

So, the IACR held an election, but one of the three trustees lost their private key, which prevented them from verifying the results of the election. Forcing them to start over.
The cryptography association was foiled by key management.

picture of text. For this election and in accordance with the bylaws of the ACR, the three members of the ACR 2025 Election Committee acted as independent trustees, each holding a portion of the cryptographic key material required to jointly decrypt the results. This aspect of Helios' design ensures that no two trustees could collude to determine the outcome of an election or the contents of individual votes on their own: all trustees must provide their decryption shares. Unfortunately, one of the three trustees has irretrievably lost their private key, an honest but unfortunate human mistake, and therefore cannot compute their decryption share. As a result, Helios is unable to complete the decryption process, and it is technically impossible for us to obtain or verify the final outcome of this election.
This IACR election news is so relatable
Did you know?
Keccak is everywhere, quietly protecting real systems, such as:
• Connected devices checking data integrity
• Firmware updates verifying authenticity
• Embedded products securing messages
• PQC standards like ML-KEM, ML-DSA, and SLH-DSA

Hot take: I hate to say it, but this is silly. Mathematicians have known for at least a century that you can replace imaginary numbers with 2x2 matrices of real numbers. Would the result be useful? Sounds like the answer is no. #quantumcomputing www.quantamagazine.org/physicists-t...
Doing some profile editing --- this should really be a pinned post, not my bio!
In his book The Mathematics of Secrets, Joshua Holden takes readers on a tour of the mathematics behind cryptography—the science of sending secret messages.
