Patrick Kennedy, tom’s Hardware, Haswell-Based Xeon E3-1200: Three Generations, Benchmarked, here. Ever wonder how much memory bandwidth your cash register needs in Haswell to breakeven in performance with a high end Sandy Bridge server chip? DynaRack – when you need to place an order … now.
Comparatively, Intel’s high-end Xeon E5 brand, intended for more compute-intensive workloads, supports up to quad-channel memory configurations and registered DIMMs. That gives those LGA 2011-based platforms the ability to address hundreds of gigabytes of memory. Back when Sandy Bridge first surfaced, 32 GB seemed like a lot of RAM for a small server or workstation. In 2013, we see high-end desktops sporting that much (particularly easy across eight memory slots).
Peter Woit, Not Even Wrong, Love and Math, here.
A large part of the book is basically a memoir, recounting Frenkel’s eventful career, which began in a small city in the former Soviet Union. He explains how he fell in love with mathematics, his struggles with the grotesque anti-Semitism of the Soviet system of that time (this chapter of the story was published earlier, available here), his experiences with Gelfand and others, and how he came to the US and ended up beginning a successful academic career in the West at Harvard. I remember fairly well the upheaval in the mathematics research community of that era, as the collapse of the Soviet system brought a flood of brilliant mathematicians from Russia to the West. It’s fascinating to read Frenkel’s account of what that all looked like from the other side.
Josiah Neeley, Not Quite Noahpinion, The Science of Hippie-Punching, here.
For those not in the know, “hippie-punching” refers to when someone (usually but not always on the center-left) attacks someone farther to their left as a means of gaining credibility and support with the general populace. The term appears to date from 2007, but the practice itself is far older. Bill Clinton, for example, was an expert hippie-puncher, and the term itself seems to be an oblique reference to the 1968 Democratic convention, when anti-war protesters battled Chicago police under the control of Democratic mayor Richard Daley (the nearest right-wing equivalent to the term “hippie-punching” is “that time when William F. Buckley kicked the Birchers out of the conservative movement”).
