During the five years (already!) I’ve lived in Berkeley, I’ve always be faithful to the East Bay Express (EBX), which stayed strong when the Bay Guardian went down. I have great memories of columns from Anna Pulley, the culture notes from Sarah Burke, and the movie critics from Kelly Vance.In these years, I’ve collected a cuts from the paper, which I believe capture the atmosphere of the East Bay ca 2015. Here’s a few: Continue reading
Around me, all I see is the blue glow of phones illuminating the faces of people.These days, we get so many things to discover, information to watch, and we’re getting addicted.
What I fault newspapers for is that day after day they draw our attention to insignificant things whereas only three or four times in our lives do we read a book in which there is something really essential. – Marcel Proust, In Search of Lost Time
This year I’m chairing the Computational Imaging session at the SPIE Defense + Commercial Sensing, in Orlando, Fla., April 16-19, 2018, together with Aamod Shanker. We have invited a lot of amazing speakers and we are organizing a panel discussion on the trends in computational imaging.Here’s the program:SESSION 6 TUE APRIL 17, 2018 – 11:10 AM TO 12:00 PM
With increasingly tight beamline specifications, optical modeling software becomes necessary in order to design and predict the performances of conceptual beamlines. This becomes particularly true with the advent of highly coherent light sources (such the proposed upgrade of the ALS), where additional considerations such mirror deformation under heat load and effects of partial coherence needs to be studied. Luca Rebuffi will present the latest features of OASYS/Shadow, an optical beamline modeling tool widely used in the synchrotron community and show how to get started with beamline simulations.https://github.com/awojdyla/ALS-U_ExamplesProgram: Continue reading
Self-reference is cornerstone in Hofstadter’s Godel-Escher-Bach, a must read book for anyone interested in logic (and we shall rely logic in these days to stay sane.)Here’s a bunch of examples of self-reference that I found interesting, curated just for you!Barber’s paradox:
The barber is the “one who shaves all those, and those only, who do not shave themselves.” The question is, does the barber shave himself?

A single chip such has Intel Xeon Phi has a computational power in excess of 1TFLOPS and features more than a hundred billion transistors. Few people outside the world of semi-conductor engineering appreciate this, but that is a fantastical number: 100,000,000,000. If every transistor was a pixel, you would need a wall 0f 100 x 100 4K TV screen to display them all!Over the past fifty years, the semiconductor industry has achieved incredible things, in part thanks to planar technology, which allowed to exponentially scale the manufacturing process, following Moore’s law. But it seems that we’re about to hit a wall soon.Let’s give an overview of where we stand, and where do we go from here! Continue reading
