Yes, but it is significant that an industry leading company chose it over a RTOS or other embedded system for a high volume project.
Why? Intel hasn't contributed anything to the project to my knowledge.

He also said: if you are running a system and you don't trust your users, you should definitively disable Hyperthreading. Hence I believe hyperthreading is an option disabled for sane defaults.
Are scripts loaded in a web browser considered "users". If so, don't most people run systems which cant trust all of their users?
If you don't trust yourself to use the web safely, then put limits on what a naughty script can do. One option is to disable hyperthreading.

One must consider the potential damages that can happen when the default is wrong, as it’s nigh certain that people are going to be careless and not change it. If the desktop PC has wrong default the performance is bad. Still functional though. If in case of VM the default is wrong we will read another headline about how N million customers of $company got their personal data leaked.
I think we'll read such headlines regardless of that setting :-P. I'm actually wondering if there should be some sort of premade "profiles" when it comes to default settings. Debian for example is used in a lot of contexts so perhaps it'd make sense to have a way to ask you what sort of usage you'll do when installing and provide different defaults based on that (not just at the initial installation time but also whe…

I will agree hardware still lags but for the target of servers and serving its fine. As far as BSD being a mess after base I completely disagree. Using and understanding a package manager makes life pretty simple. That said if the Linux community did that they would probably realize how silly containers are :)
Linux uses a bunch of package managers, it doesn't solve anything yet creates the problem of "X isn't in the repo, now what?".
You also need to do this for any pipeline for any OS.

when I said "Work on the systems" I meant support maintain care and feed. Linux has become mainstream so there are more people in the talent pool to pay to support it. Windows ... has more so it is cheaper BSD simply doesn't have enough people who know the system well enough to support it Paying 5 developers to build something cool doesn't mean you have the support system to run it.... You actually need people who un…
there's only slightly more learning curve between Linux Distro X vs BSD Y as there is between Linux Distro X and Linux Distro Y. In some ways & depending on the situation, moreso, since linux distros are often trying to do things drastically different from each other in order to differentiate themselves, whereas BSD's are often sharing code because of the small developer base, sharing-compatible license, and lack of…
Used to be a system admin could modify a kernel module in linux. These days its getting hard to find one who can use the CLI properly

The difference is because of the license. GPL license (created by Stallman, btw) won over BSD license. The emergence of a GPL-licensed kernel was inevitable. If Linux didn't appear when it did, some other kernel would appear. Maybe folks would have more motivation to work on Hurd, and it would be the main kernel for everything now.
Why is that the case? Isn't the BSD license more relaxed? I would think companies like RedHat would have liked the BSD license more.

Your desktop PC is regularly running largely unverified code, some of it potentially hostile: all the javascript in your browser.
Browsers have mitigations in place, don't they? Aren't they enough, at least on paper?

Not if hyperthreading is enabled. The point is that it's a hardware flaw, so any software mitigations can be bypassed.

Tiresas' prophecies come true because of a poetic or literary recursion built into the Oedipus cycle or the Oresteia or whatever. (I'm AFK, where K means "my library.") So when the guy to whom Tiresias prophecies that said guy will commit patricide in fact kills his father, he does so because he tried to not kill his father, and in attempting to escape his destiny, inflicted it upon himself. Stallman's apocalyptic ra…
The analogy of Cassandra is inferior because: 1. Cassandra is usually at the center of attention, an object of desire to Agamemnon and his troops, an object of hatred and jealousy to Clytemnestra and Aegisthus. Tiresias isn't nearly as ostentatious, and mostly exists passively in the background, waiting until someone else asks his opinion on something. Tiresias gives off a kind of awkward vibe, much like Stallman, co…
