Crypto Paper: RSA destroyes vis Schnorr

https://eprint.iacr.org/2021/232 Cryptology ePrint Archive: Report 2021/232 Fast Factoring Integers by SVP Algorithms Claus Peter Schnorr Abstract: To factor an integer N we construct n triples of pn-smooth integers u,v,|u−vN| for the n-th prime pn. Denote such triple a fac-relation. We get fac-relations from a nearly shortest vector of the lattice L(Rn,f) with basis matrix Rn,f∈R(n+1)×(n+1) where f:[1,n]→[1,n] is a permutation of [1,2,...,n] and (Nf(1),...,Nf(n)) is the diagonal of Rn,f. We get an independent fac-relation from an independent permutation f′. We find sufficiently short lattice vectors by strong primal-dual reduction of Rn,f. We factor N≈2400 by n = 47 and N≈2800 by n = 95. Our accelerated strong primal-dual reduction of [Gama, Nguyen 2008] factors integers N≈2400 and N≈2800 by 4.2⋅109 and 8.4⋅1010 arithmetic operations, much faster then the quadratic sieve {\bf QS} and the number field sieve {\bf NFS} and using much smaller primes pn. This destroyes the RSA cryptosystem. Category / Keywords: secret-key cryptography / Primal-dual reduction, SVP, fac-relation Date: received 1 Mar 2021 Contact author: schnorr at cs uni-frankfurt de

Homebrew 8 1/2 Digit DIgital Voltmeter (DVM)Hackaday: Homebrew Metrology The CERN Way. https://hackaday.com/2021/02/26/homebrew-metrology-the-cern-way/ Jim Bell's note:. In 1974, one of my early electronics projects was to design and build a 4 1/2 Digit DVM, including a custom-designed printed circuit board that I laid out and etched. It used a MK5002 counter chip. https://www.datasheetarchive.com/?q=MK5002

Human stem cells can be converted into insulin-producing cells to control blood sugar levels – and in effect “cure” type 1 diabetes https://www.drwf.org.uk/news-and-events/news/researchers-discover-potential… Avalanche has already established itself as a good alternative to Ethereum for launching DeFi applications, as its fast, low cost transactions are carried out in a secure and scalable network. https://coinlist.me/news/biconomy-to-bring-gasless-meta-transactions-to-ava…

misbehaving system halting work
by Karl 26 Feb '21

26 Feb '21

The work i landed on for a while was software called 'brainflow'. I am actually part of the organisation now. I am presently stuck on https://github.com/brainflow-dev/brainflow/pull/247 and don't really know what to do. My system apparently has corruption, but it is pretty complicated for me to resolve that, so I am just debugging things on the corrupt system.

[spam] Fwd: Red Hat Renewal - Karl Semich - (11826708)

---------- Forwarded message ---------- From: Karl Semich <0xloem(a)gmail.com> Date: Fri, 26 Feb 2021 15:01:19 -0500 Subject: Re: Red Hat Renewal - Karl Semich - (11826708) To: Ella Eleazar <meleazar(a)redhat.com> Hi Ella, I let my subscription lapse because I was frustrated at redhat's lack of pgp signatures in their image downloads. I opened a ticket and it had no velocity for a year. However, it's been convenient for me to continue using the system, even though the subscription has lapsed. How do I pay you guys to re-enable yum on my system? The subscription doesn't seem to be listed in my account on your site any more.
