Another case where detailed commit messages really really help.

It blows my mind that any project decides not to provide detailed commit messages when the benefits are so massive...!

Sometimes I feel like, in an effort for everybody to try to present themselves as hugely empathetic, society has become a hell of a lot less empathetic in reality.

kernel compile and... (plus now freezes afterwards).

It was working before so it's just strange.

I reapplied thermal paste and reorientated the heat sink and added an extra fan, no dice.

So @lkundrak often posts about doors, showing off Brno doors as if they are special, well now I have to show the end game of doors and yes it's British.

Sorry not sorry

Since I'm being boring and moaning about the scam de jour again, let me also go 'WTF' about people blindly taking the word of people who stand to make BILLIONS OF DOLLARS on this topic at face value?

Like I don't fucking want to hear 'the CEO of nvidia says AI stuff is incredible', yeah OBVIOUSLY he says that, I mean jesus christ how naive are people??

"I asked the local butcher whether he thinks more people should buy meat and he said they should!"

WOWWWW!!

For me a lot of what is aggravating about UK trains is the total contempt they have for their customers, expressed often and casually.

For instance, running trains 4 cars short in the rush hour with only vague hand wavy excuses (translation it would cost money for them not to)

And this morning, train crews blocking 50%+ of the car park with zero warning or alternatives and taking up a bunch of spaces unnecessarily.

Contempt.

While there are sometimes LWN articles/posts/etc. about things I cover in the book I generally try to avoid them as I've often found them to be counterproductive because:

a. I end up taking on assumptions the author did or speaking with 'their voice' rather than seeing for myself
b. The author might have made mistakes/glossed over things
c. The author is probably talking about a kernel version other than v6.0
d. The author often has a bias towards a certain problem/point of view that isn't 'exploring mm from bottom up'
e. I might miss things the code shows.

Therefore 99% of all I do comes from the source + me banging my head against the wall

Unreal that republicans are using Ukraine for scoring politican points.

What these fucking cowards don't get is that if we don't stop Putin in Ukraine, it'll be a fucking NATO country next.

Because if he pushes and the west immediately or eventually capitulates, what's to stop him?

Will we really have a strategic nuclear war? Or just let me conquer more territory?

Helping Ukraine defends themselves is the, and forgive me for the brutal way of putting it, most 'cost effective' way of dealing with this very serious threat.

Of course there are moral cowards and morons everywhere who want to give in. The very same who claim they'd not have given in to Hitler, crock of shit.

I find the 'death of the high street' people tiresome. They're almost as bad as 'this capitalist system which has lifted billions out of poverty and which I owe everything is utterly broken' people, but you know, not quite.

Both share a total misunderstanding of where wealth comes form. It doesn't grow on a tree waiting for a big daddy or mummy in the sky to hand out to people.

It is forged by enterprise. And enterprise lives and dies on demand, if the demand isn't there, then what? Are we supposed to fund businesses as a charity serving confused nostalgic people?

The high street in the UK is dying because it was and is largely shit, and something better came along.

Shops that offer something different/better than online will do well, those that try to sell overpriced tat in a shabby retail space making no effort are, thankfully dying.

Woolworths was a shit hole, BHS was a shit hole, sorry. And they died because people could find far better elsewhere.

It's this weird rose-tinted thing. I was born in the 80's and saw how it was pre-internet, and guys, what the fuck? 🤣

I know that people say wayland is the future and nobody cares about X yada yada, but it is pretty frustrating when wayland is broken for a whole bunch of things.

It's like a trend, similar to flatpak, the devs don't care so it doesn't get done but simultaneously you have to 'embrace' it even though it degrades your experience.

I made a bunch of kernel scripts to make life easier working with configuring/building/running a kernel in qemu etc.

They're a bit arch-specific and rough but in case anybody might find them useful :)

It takes a certain type of person who, when you pull forward to park in a space, indicating the whole time, drives in and takes it.

A certain kind of cunt who one day will do that to a nutter and have a bad outcome.

Luckily I'm British so I just tutted under my breath and found another spot

As interesting a technology as bpf is, I really do worry that some aspects of it are just a way of working around the GPL and exfiltrating things from the kernel.

It is potentially (very!) useful to be able to hook into things, but when you get to the point of actually changing kernel behaviour will it not be tempting for companies to implement 'secret sauce' they don't have to contribute back?

@lisyarus I still find rust appealing as a language but there's people in the community who really really put you off.

Also I secretly still love C (not so secretly)
