Yet another reason to never touch that piece of shit language ever again:
CppCon leadership and the C++ Foundation board have worked in secret to protect a person convicted of rape and possession of Child Sexual Abuse Imagery. They have refused any transparency into a process where they have decided to allow this person full access to CppCon as an attendee, speaker and trainer. This person is well-known and trusted in the C++ community.
For some reason a lot of material around this avoids naming the person. He is Arthur O'Dwyer. Here is an article about his arrest and conviction: https://dailyvoice.com/new-york/yonkers/news/sex-offender-convicted-of-raping-drugged-victim-reports-move-into-yonkers/773166/
Fuck whoever it is, but I cannot say that I know a single person involved in the formalization of any language and I'm not starting now.
I've only used C/C++ and Python for the last ~10years. Fuck Java, the last thing I worked on was a rewrite of Java mixnetworking software, totally interoperable with Java version peers. Went from 1.5GiB memory consumption out of the box to 15MiB.
Sounds like the Java version wasn't written with aggressive GC reference culling in mind -- it will never be as memory-efficient as a purpose-built C/C++/Rust program, but 1.5 GB sounds egregious.
