Parsing time stamps faster with SIMD instructions
Indeed! It was a while ago but Im quite proud of the fast timestamp functions I made for Java after the standard library timestamp performance turned out to be critical to some data pipelines I was working on. The fastest way I found for the calendar was to use a precomputed table etc.

Under Linux, libSegFault and addr2line are underrated
A newline is missing in the example code. As given there's a segfault at line 5 not line 6.
However, the code at https://github.com/lemire/Code-used-on-Daniel-Lemire-s-blog/... shows it's indeed at line 6, because it has an extra newline after the '#include '.

Escaping strings faster with AVX-512
Added this pull request with some interesting results.
There's a copy of the loop used on the escape function inside the avx512_escape function [0]. Is it needed or just a copy and paste mistake? (I know nothing about vector instructions)
