Bcrypt at 25
As one of the creators of bcrypt back in 1997, I find it somewhat surprising that, 25 years later, we still rely heavily on passwords. My initial encounter with password security took place in 1993 at the University of Hamburg. Having just discovered Unix, I was fascinated by a service called Yellow Pages that allowed…

Parsing integers quickly with AVX-512
If I give a programmer a string such as "9223372036854775808" and I ask them to convert it to an integer, they might do the following in C++: std::string s = .... uint64_t val; auto [ptr, ec] = std::from_chars(s.data(), s.data() + s.size(), val); if (ec != std::errc()) {} // I have an error ! // val … Continue reading…

Emacs GUI Library
Lately, my Magit buffer broke once again because of something weird going on with major mode, and I couldn’t stash or commit hunks unless the point was at the beginning of the line. That once again reminded me that Emacs UI is not really a UI, all of it is mere text with a bunch of properties slapped on top.
