So...?
I can only write "hello world" in shell script, Python, & Rust.
Granted, any moron should be able to figure out print("hello world"), echo "hello world", & cargo new myProject --bin .

Linux is doing all is possible to be the worst among the operating system platforms.

INB4 JS VM exploit that hops off to the kernel using a local privilege escalation vulnerability, then updates your motherboard's BIOS or CPU's microcode with an unsigned image. Or maybe stealing your Git SSH key through Spectre for someone to put malware in your code without you realizing.Last edited by GrayShade; 11 November 2019, 02:13 PM.

If you don't give a rat ass about security on your system just pass mitigations=off at boot and you are golden but don't expect everyone to follow that short sighted idea of yours of let half the planet earth exposed to something this massive because your benchmarks look ugly.
Since my computer is not keeping the secrets of NASA or bank deposits, I don't want my performance to be reduced more 10% for protecting nothing so important.
How about a slider where the user can decide the comporomise between security and performance?
Plus, when it comes to the security of Linux desktop, In my opinion it's either close to 0 (zero) or just a joke.
Which Linux distro offers an option to control the installed programs, where I can say what they are allowed to do and what they are not allowed to do?
Which Linux distro offers and options to control the privacy part of security of the installed programs where I can say from which devices (webcam, mike, scanner, hard disks, flash drives) they are allowed to read from and from which they are not allowed?
Which Linux distro offers a easy to use firewall where I can say which programs are allowed to use the network and which are not?
Even Windows has a firewall popup asking to allow or deny programs wanting to access the network.
So I care about security, but I wish the most important things would be solved first like the control / sandboxing of the installed programs.
I'm tired of praying that the installed programs will behave nice when I run them or insert the requested superuser password and they get god-like powers and they can destroy everything if they want.
Why Android can have this and Linux can't.
Where is the so called security of Linux?
So I'm sorry, but I'm tired of these security measures on on top of another that just reduce the performance of Linux desktop.
How about investing more into the other type of security that I said above?
