CADO-NFS: Crible Algébrique: Distribution, Optimisation - Number Field Sieve
CADO-NFS is a complete implementation in C/C++ of the Number Field Sieve (NFS) algorithm for factoring integers and computing discrete logarithms in finite fields. It consists in various programs corresponding to all the phases of the algorithm, and a general script that runs them, possibly in parallel over a network of computers. CADO-NFS is distributed under the Gnu Lesser General Public License (LGPL) version 2.1 (or any later version).

[Cado-nfs-discuss] Factorization of RSA-250
This computation was performed with the Number Field Sieve algorithm, using the open-source CADO-NFS software [2].
The total computation time was roughly 2700 core-years, using Intel Xeon Gold 6130 CPUs as a reference (2.1GHz): [...]

Could the coronavirus be the best thing to happen to higher education?
Universities should embrace this staff engagement and seize the opportunity to transform pedagogy to meet the needs of the next generation of students. Incoming undergraduate and graduate students will have elevated expectations about the use of technology on campuses. In fact, they may already be accustomed to technology-enabled pedagogy, since schools in an increasing number of districts are light years ahead of higher education in this regard.
Once we get beyond the current crisis, universities should shift the focus from basic training on tools to more advanced training incorporating course design and assessment of learning. Faculty enthusiasm may well be less than we are seeing now, but if we can get the messaging to resonate with faculty, they may just start participating in droves. That messaging should celebrate their current achievements with online tools while also recognising their pain points, and offer the training as an opportunity to build on that success and solve their technology-related teaching challenges.

Never Let A Crisis Go To Waste
Elsevier and the other oligopoly academic publishers have reacted similarly in earlier virus outbreaks. Prof. John Willinsky pounced on this admission that these companies normal restrictive access policies based on copyright ownership slow the progress of science, and thus violate the US Constitution's intellectual [sic] property [sic] clause:
That Congress shall have Power...To promote the Progress of Science and useful Arts, by securing for limited Times to Authors and Inventors the exclusive Right to their respective Writings and Discoveries.
Below the fold I provide some details of his proposal.

Samsung, Red Hat to Work on Linux Drivers for Future TechThe metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. |
