The XPS 13 9380 is available with Linux pre-installed, why would you want to mess with that? Or was it a fun/hobby thing?

I feel that going from 8W to 3W, while gaining a more usable system that also sits on ZFS instead of ext4, is more than enough reason. ext4 doesn't detect corruption . How am I supposed to trust it?

It seems like a good deal but what about the support and the upgrade path from Dell?

I get what you're saying about the filesystem. Personally, I use par2 for the most important things (photos).

I've seriously got to look into running arch with a clear linux kernel. I knew they did some pretty serious optimization work, but this is definitely impressive.

Most of the bloat isn’t from the kernel. That’s the last thing you really optimize after getting rid of all the background services, startup tasks, etc.

Clear kernel performed better in every single test run by phoronix, except one (because it has retpoline and others did not). https://www.phoronix.com/scan.php?page=article&item=arch-ant...

What about it? It doesn't seem to be enormously useful, given I can do so much better on my own.

I got the laptop to have well-supported hardware, not because I was expecting a lot of help from Dell.

I'd love to hear more about the tweaks you've done to Arch. I've gone little beyond a few power management things myself (On a Thinkpad X1C Gen 6). I get decent battery life, but I know it could be better. And giving up Arch would be a tough sell to myself.

The thing with arch is it’s mostly not more tweaks that give you better battery, it’s not having all the crap that Ubuntu preloads running that makes that happen.

Totally, Arch feels snappier in the same hardware that I am surprised that my machine can hold a lot of power for development.

Is that all there is to it, just well supported hardware? Dell didn't configure Redhat in any way, to make better use of the hardware? I'm thinking trackpad, sleep and hibernation, graphics etc.?

Folks think I'm crazy for using Arch as my main dev machine. I'm not an Ubuntu hater at all (it runs my main server in the basement at home)... but it'd be awfully hard to go back to using it as my main machine.

Really? Arch is... boring. Once you've set it up, nothing happens without your permission and you can just keep developing away. Sure you have updates imposed on you, but you can delay them a bit if you dont have time right now, and its not like upgrades are indefinitely avoidable on any other OS. Using Arch often gives me advance warning that my apps will break on users machines due to changes in libraries. I see th…

Yeah, for me, it's "just right". Most detractors claim it's "bleeding edge". What? just because it's got something newer than Postgres 9.1 available?? (this was my argument against Debian/Ubuntu for a long time)

Totally agree that it's a great daily driver. It has EVERYTHING!

Do I understand correctly that the motivation for this is that the rear-view camera on the Chery Exeed LX runs Linux? Is it a good idea to ship a car with safety components running Linux?

I miss the days when I could reverse without the aid of a computer.

How nostalgic! Mind you, I say that in a good way! This brings me back to the heydays of Sun Microsystems where they controlled both the hardware (SPARC) and the operating system (Solaris). Sun didn't hesitate to use this to their advantage. With Clear Linux, I see Intel doing some very similar things. Yes, this was just a story about boot time, but it led me to take a look at Clear Linux and it looks like it could b…

I think Sun must've tried and failed. Boot times on late 90's era Solaris/Sparc systems were atrocious compared to Linux/x86 systems of the day.

Just to underscore this, here's a video of some guy booting an Ultra 45, the last workstation Sun ever made. It takes 30s just to go from power-on to firmware initialized and another minute and a half to start Solaris. Older equipment such as a SPARCStation 20 would take much longer.
