Parsing time stamps faster with SIMD instructions
It's not bad at all https://github.com/lemire/Code-used-on-Daniel-Lemire-s-blog/...

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 '.

Technical Blogs You Recommend?
Dr. Daniel Lemire's blog: https://lemire.me/blog, covers lots of technical items on optimizations in various programming languages, Lemire's work is currently in use across a number of projects and he consistently delivers fantastic improvements, he usually accompanies these improvements with a blog post describing what he did. He also occasionally posts interesting Science and Technology links on various topics not limited to tech, but health and education as well.
- suggest some c language blogs....

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)

Ask HN: SQLite in Production?
Perhaps the OP means OsQuery: https://github.com/osquery/osquery
OsQuery is an SQLite extension consisting of hundreds of virtual tables

Osquery: An sqlite3 virtual table exposing operating system data to SQL
There's at least one open data quality issue for `process_open_sockets` on macOS[1]. It's a few years old however and, if you aren't seeing that casting error, you probably aren't hitting it. But that's a good example of the kind of debt that's been built up over time.
(In terms of general purpose/flexible tooling, I'm not aware of a close replacement for osquery.)

Alternative to Endpoint Protector?
From a self hosted standpoint OSQuery or Wazuh are your best bets for monitoring USB devices. Windows makes blocking really challenging and I’m not aware of any “free” solutions that attempt it.

Configure auditd to monitor host activity: https://izyknows.medium.com/linux-auditd-for-threat-detection-d06c8b941505 or osquery: https://osquery.io/ (or similar software: filebeat for example).
