Thank goodness that Linux is consistent and has no bugs :-) Ubuntu still doesn't let me change my IP address to a static one via the UI and video drivers still crash or result in hours of googling and reading contradicting articles on how to change xorg.conf Software has bugs. Operating systems are hard. It doesn't matter where you will go, you will most likely deal with similar issues. Whether it be Linux, Windows o…
My Ubuntu 16.04 LTS X-Windows just froze today multiple times, not even changing to virtual terminals was possible, only hard reboot.

The internet is replete with opportunities for getting triggered and starting flamewars. For HN not to sink into a deeper circle of hell, we all need to resist these temptations. So could you and everyone else please not take HN threads on generic, divisive tangents in the future?

#85mov rax, 1
mov rdi, 1
syscall
and it would bring down the entire OS (kernel panic) when run by any user mode application under a standard non-root user. Took a few releases for them to fix that. I stopped trusting them from a low-level reliability perspective since then.
Fuzzing their system call interface may not have been a bad idea.
P.S. XNU is an interesting as it lets userspace use Mach syscalls as well as a bunch of BSD system calls directly. Probably esoteric interactions between them are not very well-thought-out. (I hope I am not offending Avie Tevanian here :))

#86I think High Sierra is the worst Mac OS release yet. I’m sure there’s a cognitive bias partially to blame (since it’s the most recent) but it looks like we are way past that.
The mach kernels in general are buggy, regardless of the release. e.g. I'm pretty sure they end up delivering SIGPIPE to the wrong thread in some circumstances on Sierra. There is also a problem with recvmsg not returning control messages some time. Another reason they killed OS X Server maybe.

I'm the initial bug reporter. This machine is on 10.13.3.
I don't even use a mac but I've heard terrible things about High Sierra, is it really that bad? Seems like they pushed a bunch of substantial changes to the kernel.
I've waited a bit after the "root" security issue, and now I prefer to be on the latest version.

The difference is you pay a huge premium for Apple products, Linux distros are generally free (unless you want enterprise-style support). The same criticism applies to Windows - give it away for free and I might care less about crashes and the huge slide in quality over the last ~5 years.
I'm happy to pay a premium to never again have to deal with xorg.conf. All platforms come with a cost.

Xorg.conf is a delightful stroll through a meadow compared to the nightmare fuel that came before, and in setting Linux (Kali,Ubuntu) on several machines of various spec over the last weeks, it has Just Worked.
