Exactly. The PAP-managed govt is rich. The citizens are poor. That’s what I told an Aussie group of tourists who saw elderly folks cleaning tables at Chinatown Complex and asked why is this happening when Sgp is a rich country. Sad but true.

Are Meta/Facebook servers using Fedora Linux?

Subject: Are Meta/Facebook servers using Fedora Linux? Good day from Singapore, I have just come across this article. Article: Fedora's FESCo Rejects The Idea Of "-fno-omit-frame-pointer" As Default Compiler Flag Link: https://www.phoronix.com/news/Fedora-Rejects-No-Omit-FP [QUOTE] As a change proposal first initiated by Meta/Facebook developers, they wanted -fno-omit-frame-pointer and -mno-omit-leaf-frame-pointer to be added to the default C/C++ compilation flags. ...snipped... Meta engineers believe that any performance cost is small and worth it while SUSE engineers previously cited around possible 5~10% regressions. [/QUOTE] From the above quotes, I thought that Meta/Facebook servers are using Fedora Linux, or at least Linux servers. Anyone can confirm?
