Engineering a Safer World | Lobsters
"For anyone unfamiliar, Nancy Leveson did a lot of pioneering work in bringing the kind of thinking in fields like aerospace to software safety. She pushes analyzing requirements and proposed solutions along human, technical, and environmental lines. She and her collaborators also did safety analysis on major projects like an air traffic control system.

Prior book was Safeware. Sample chapters from it here. Glad this one is open access. :)"

How strtod() Works (and Sometimes Doesn’t)
"Converting decimal strings to doubles correctly and efficiently is a surprisingly complex task; fortunately, David M. Gay did this for us when he wrote this paper and released this code over 20 years ago. (He maintains this reference copy of strtod() to this day.) [...] I’ve spent considerable time reverse engineering strtod(); neither the paper nor the code are easy reads. I’ve written articles about how each of its major pieces work, and I’ve discovered bugs (as have a few of my readers) along the way. This article ties all of my strtod() research together."
