Points from the flip side:

- the Linux project is very likely to stick to simple, fast elements of Rust (based on the excellent approach of the Linux/Rust devs thus far)

- the more Rust is used, the more work will be done to improve its performance

- you can still build a kernel on a low-powered device... i've built kernels that took > 12 hours on, for example, PA-RISC boxes that were once regarded as beefy :-)

- most people don't (and shouldn't) compile their kernel, and by most I mean more than 99%

The Trustworthy Systems group at UNSW has been doing a lot of research (and verification) of temporal isolation on seL4.

But a row-based database is not a data warehouse, and a columnar database doesn't care about column order because they're not stored together.

That was never the objective, nor the result. It's just an ill-informed meme.

If you knew the GNOME project or any of its contributors over a long period of time, you'd know that this is absolute poppycock. If anything, the GNOME 2.0 approach was an allergic reaction to years of overcomplicated nerd software. Consider that, prior to 2.0, Enlightenment was once the official GNOME window manager.

A few thoughts:

- the seL4 team definitely works on user space stuff (see the rest of the repos in the seL4 organisation on GitHub), but it's very basic thus far. there is some design work going on to standardise some user space bits and pieces. but i don't think they're ever going to build an top-to-bottom opinionated operating system stack – that's for other people to do.

- it's not a solely academic exercise, it is being used in industry, but most of what everyone sees is the output of the research group, which gives it an academic sheen.

- the unfamiliar internals and implementation are driven by a fundamental difference between seL4 and almost all other kernels... it is verified.

Yes, it requires a little bit of work and scheduling. Very different to running the entire thing yourself, though!

OK, now run the same remediation process except now you're maintaining all of your high availability database clusters yourself. :-)

RDS, simple as it may seem on the surface, is one of the things I'm most grateful for in AWS.

My favourite interaction with negative dentries was with PHP's curl library, built with NSS for encryption. NSS would do some kind of filesystem performance check, intentionally opening lots of files that didn't exist. At one point, every server in a large autoscaling group was spending 10GB EACH just on the dentry cache. :-)

There were plenty of us who knew – and said – that "cryptocurrency" was borne of technical, political, economic, societal ignorance when it started. Now it's just more obviously terrible.

Don't make me tap the sign.

Climate-destroying techno-libertarian accelerationists will hurt everyone.

You misspelled "fellow human beings".

Just don't believe any web ads featuring his name or image – all scams. He must be comfortably offline and in blissful ignorance. Imagine.

One day, probably not very soon, Americans will learn that universal healthcare is freedom.

"You don't need to wear masks" was bad advice from well-meaning people who should've known better. The researchers who did know better couldn't push past deeply-entrenched anti-miasma attitudes quickly enough.

"Use social distancing and isolation to avoid COVID and get vaccinated as quickly as possible" is good advice from well-meaning people who do know better. Sorry it's unpleasant, but if the USA behaved rationally, there wouldn't be 750K+ dead today.

Sweden readily admits that its approach was a terrible mistake. It's just not as embarrassingly bad as other countries, particularly ones that, with sensible leaders, should have done much better (UK, USA).

"I know how to get things right."

Ah, you're one of those people. Sure. :-)

Nah, you're really not.

Most of the time, particularly if you're not writing libraries, Rust feels like a dialect of Python that wants to help you get things right.

Every retelling is subjective. This will be too. Complaining that "most documentaries" have "a point of view or ideology" makes you all the more susceptible to it everywhere else.

Dryers and video games are useful.

"Lego" or "Lego blocks", never "Legos" (the title of the article gets it right)

You'll most likely find readably useful (historical) stuff in presentations at Linux conferences and articles in LWN.

Linux has supported big.LITTLE style systems for a long time, and has been improving scheduler support for them for about 10 years.

(The main gap you tend to see in the Linux world is integration further up the stack. For example, allowing app developers to nominate a core preference by configuration. That's partly due to the assumption of the distribution model.)

That's what systemd does for you.

If the author is reading, the phrase,

> Please follow me in my rabbit hole.

... means something rather different to what you intended, which is probably,

> Please follow me down the rabbit hole.

But thank you for the giggle. :-)

Like I said.

Please do not suggest that one of the greatest minds of our era should have adopted the writing style of one of the greatest nitwits of our era.

I know Raph for his graphics, typeface and desktop work, so seeing his name pop up in this was a surprise! Can't keep a good genius down.

Are you confusing "making fun of" with "offensive", or "punching down"? These are not the same things.

Yes! And it's worth getting comfortable with change and learning from it, instead of being weird and reactionary about it.
