A Quadrillion, To Scale - Ignis Fatuus
http://www.ignisfatuus.com/2010/08/27/a-quadrillion-to-scale
Aug 27, 2010. A Quadrillion, To Scale. To help to better visualize the relative weight of these amounts, I’ve thrown together this handy illustrated guide. The scale is more or less consistent, so walking through the next 6 images will hopefully show how these orders of magnitude stack up. First off, 1. To stack these little guys ten high, ten wide, and ten deep, it would take 1 thousand (1,000). Of of the original unit of 1:. That’s roughly one for every person living in San Jose, America’s ...To stack ...

The higher-order function ‘fold’ | Gregor Ulm
http://gregorulm.com/the-higher-order-function-fold
The higher-order function ‘fold’. When students encounter higher-order functions in functional programming, they are normally exposed to the following three first: map, filter, and fold. The higher-order functions map and filter are intuitively accessible. With the former you apply a function to each element of a list, while the latter retains only elements for which a given predicate is true. One might want to implement those functions in Haskell as follows:. Foldr (*) 1 [1,2,3] (*) 1 (foldr (*) 1 [2,3]...

Diceware, Security Theater, and Women in Tech Propaganda. I recently came across an article on ArsTechnica that was the epitome of the inane More XX chromosome carriers in Tech propaganda that has been infesting this industry for quite some time. Of course, the problem is not that there should be no women in tech, but that there is a celebration of pseudo-achievements that do the industry, the organizations behind this social engineering initiative, and women themselves a disservice. That sounds like an ...

Monthly Archives: March 2015. An FFT (Cooley Tukey) for a synchronous dataflow extension to Feldspar. Unfortunately I’m not able to share most of my university course work, due to our honor code. There are some exceptions, though. For instance, the last assignment in Patrik Jansson’s MSc/PhD course Advanced Functional Programming at Chalmers University of Technology. In our project, my lab partner Niklas Logren and me collaborated with Markus Aronsson, a PhD Student in the Software Technology division in...

Navigating Cities and Understanding Proofs | Gödel's Lost Letter and P=NP
https://rjlipton.wordpress.com/2011/05/06/navigating-cities-and-understanding-proofs
Gödel’s Lost Letter and P=NP. A personal view of the theory of computation. About P=NP and SAT. Conventional Wisdom and P=NP. Navigating Cities and Understanding Proofs. May 6, 2011. How proofs are like cities. Pierre L’Enfant was not a theorist, but a designer, and in particular the designer of the physical layout of Washington D.C. Today I want to talk about why some proofs are hard to understand, not hard to discover. What do proofs have to do with cities? For all its size and immense density of peopl...
