The Jaccard index between two bit-vectors A and B is ||A intersection B|| / ||A union B|| = popcount(A & B) / popcount(A | B) Let N be the number of bits in the bit-vector. Consider A_1, A_2, A_3, ... A_i which ar

Your example proposition assumes the source code is available at no cost from the developer, which isn't necessarily the case. It's true that nearly all GPL'ed (and FOSS) software is available for download at no cost. But the

As someone who tried the same approach, I think I can help. I sold software to pharmaceutical R&D groups. As a supporter and author of free and open source software, I wanted to see if I could apply the ideas from "Selling Free Sof

When I came across that video last year I sent an email to the creator, but never got a reply. I made some of my own edge-notched cards using a computer-controlled stencil cutter. Here are some pictures - https://twitter.com&#x2F

There's an interesting connection between this and edge-notched punched cards (a special interest of mine), via a 1936 article in Nature (See https://www.nature.com/articles/137535a0 .) Quoting Kilgour's &quo

Of course not. But my question was, when was this halcyon day of yore? > Things are changing much faster today, than they were in 1950 Why are you so sure about that? The post-war era saw an incredible amount of change. By the end of the

And what I am complaining about is that NOTHING in my comment had anything do with "giving their work away for $0 and then complaining that nobody pays them $ for their work." Moreover, the linked-to essay even called out services

Your view of the "nativity of open source developers" is itself naïve. To my understanding, most people who want to get paid a reasonable amount to develop FOSS go one of two routes. 1) Service-oriented, à la the Cygnus Solutions

Thanks twik and leflandfe! Using CSS ::after resolves those highlighting and copy&paste issues I noticed. New jsfiddle at https://jsfiddle.net/hnw1zbed/2/ .

D'oh! Yup. You think I would know that by now. I'll attribute it to trying this out being the weekend, in the down times between the kids' bedtime routine.

I find it interesting to read old publications. It gives a sense of what arguments are new and what are re-treads. Here's an essay from Eugene Garfield from 1983 titled "The dilemma of prolongevity research -- Must we age before w

The job was miserable. He was VP of engineering. He, I, the VP of marketing and I think someone else left within the same week because things weren't working out. (It was only a 50 person company.) The company got bought out, mostly as
