Updated, September 18 @ 13:15 EDT (18:15 BST): Mark Perlin, the chief scientist and executive officer of Cybergenetics, says in an e-mail and telephone interview with Ars that "source code is not used to assess forensic software reliability." (More below.) The results from a Pennsylvania company's TrueAllele DNA testing software have been used in roughly 200 criminal cases, from California to Flor
The little book about OS development Erik Helin, Adam Renberg 1 Introduction This text is a practical guide to writing your own x86 operating system. It is designed to give enough help with the technical details while at the same time not reveal too much with samples and code excerpts. We’ve tried to collect parts of the vast (and often excellent) expanse of material and tutorials available, on th
Freedom to Tinker Research and commentary on digital technologies in public life There have been rumors for years that the NSA can decrypt a significant fraction of encrypted Internet traffic. In 2012, James Bamford published an article quoting anonymous former NSA officials stating that the agency had achieved a “computing breakthrough” that gave them “the ability to crack current public encrypti
R vs Python — Opinions vs Facts There are dozens articles out there that compare R vs. Python from a subjective, opinion-based perspective. Both Python and R are great options for data analysis, or any work in the data science field.

You either overshoot the short-term progress or undershoot the long. What’s surprising is not h

It was 3 in the morning, the optimal time to squeeze cycles out of the supercomputer in C
Rodeo 1.0 Release When we released our in-browser IDE for Python earlier this year, we couldn’t believe the response. Thousands of our readers all over the world saddled up and told their friends and colleagues to do the same (no more puns, we promise). That reaction, as well as the endless search for hacks to make our lives easier, got us thinking about how to make Rodeo even better. Over the pas
