This weekend, though, a thousand Israelis were murdered, kidnapped, and raped-children, babies, parents using their bodies to shield their kids, Holocaust survivors, young people at a music festival. Secular, Israeli-born, and a protege of the … err, post-Zionist radical (?) Oded Goldreich, I can assure you that Boaz has never been quiet in his criticisms of Bibi’s emerging settler-theocracy. He’s a longtime friend-of-the-blog (having, for example, collaborated with me on the Five Worlds of AI post and Alarming trend in K-12 math education post), not to mention a longtime friend of me personally.īoaz has always been well to my left politically. The purpose of this post is to salute a longtime friend-of-the-blog for a recent display of moral courage.īoaz Barak is one of the most creative complexity theorists and cryptographers in the world, Gordon McKay Professor of Computer Science at Harvard, and-I’m happy to report-soon (like me) to go on leave to work in OpenAI’s safety group. Namely: we simply need to unearth video proof that, at some point before beheading their Jewish victims in front of their families, burning them alive, and/or parading their mutilated bodies through the streets, at some point Hamas also misgendered them. There, Boaz points out that there might be a way to get Western leftists on board with basic humanity on this issue. 11): While this post celebrated Harvard’s Boaz Barak, and his successful effort to shame his into disapproving of the murder of innocents, I missed Boaz’s best tweet about this.

For the latter case, “ideal lattices” refer to a family of lattices recently used in cryptography.Į. We note that such a lattice construction from number fields can in turn be combined with Construction A to obtain further lattices, e.g., and references therein. We will explain the former technique using quadratic fields, and refer to for general number field constructions. The same terminology is used for two different view points on lattices because of the communities that studied them. Of R is an additive subgroup of R which is also closed under multiplication by elements of R. We recall that given a commutative ring R, an ideal This chapter presents two other methods to construct lattices, both called ideal lattices, because they both rely on the structure of ideals in rings. In Chapter 3, one method to build such lattices was discussed, which consists of obtaining lattices from linear codes. In Chapter 2, interesting lattices together with their parameters and applications were presented.
