Look it depends on the age of the car, but let's take an old manual car for example.

On those cars, there's a fuel map to rpm. There's actually a few maps including throttle and ignition timing. But think of a spreadsheet of rpm and fuel at a certain throttle load.

At 0 throttle: The map says to stop the engine from stealing at under say 800 rpm it needs to have fuel added at rpms lower than that to speed up the engine to avoid stalling. At 800rpm it needs a consistent amount kind of a known amount that keeps it in equilibrium. At over 800rpm it needs less fuel the more rpm it has over the idle 800rpm until it's zero fuel.

And you'll feel that, you'll feel that moment the car starts adding fuel because if you're only engine braking to a stop your car will get near that idle rpm and your engine will start adding power to avoid a stall, and your braking will diminish.

If you take an engine out of a car and try to spin it by turning the crank shaft, it will be hard to turn because the cylinders need to compress air (it's required before adding fuel and spark to explode that compressed air so it expands).

When that engine is in the car, and you don't add fuel and spark, then the cars wheels have to turn the engine and compress that air, thousands of times per minute. That force that the wheels have to send to the engine to spin that engine slows you down.

I'm thinking you think the engine itself has a brake on it.. No.

Stupid take to be honest, real people getting trafficked and stalked, domestic abuse victims being tracked for control by the abuser, and you think that's fine because google has that data about you even though nobody can use it so why shouldn't all apps be able to? Go to a women's shelter, touch grass.

This issue is far more nuanced. No it's not good Google has that data on you.

No it's not fair that automatons caused a small developer to have their entire amount destroyed without a proper review.

Both things can be true.

Hi, I run pop! Os for about a year on a mac book pro 2012. My biggest hassles are Bluetooth audio sucks (glitchy) and I had to install a wireless driver to get wireless to work at all. Other than that, it's working exactly as expected. Can recommend. It can't game, it can't play videos well because the inbuilt speakers suck (and the Bluetooth audio is glitchy), but it's plenty performant for my actual tasks. Runs smooth. I'm sure most distributions will.

I think that's a good idea, good luck with it!

I can guess at some things but let me first start with what I think is happening:

You have a gateway set. Your device sends a broadcast arp message asking 'who has ip ' and the device with that ip is supposed to send back 'me with this mac address!'.

That device is either sending it so slowly that your machine says 'I can't go past the gateway, the gateway isn't responding' which in your error message is no route to host.

Assuming that you have no custom manual network route in play.

So things that can cause that are usually link layer and layer two issues and sometimes duplicate IPs. Two devices with the gateway ip.

You should watch your mac address table and arp table (arp a) and watch if the router gateway disappears or changes Mac addresses.

Don't feel bad because you're really good at using a tool that doesn't follow your values. I use Windows during the work week and I use Linux for gaming on the weekend where I literally can't work even if I wanted to.

For me Windows is a tool box with propriatry tools that have no Linux compatibility. That's OK for me. People get emotionally invested but that's neither healthy nor helpful. No point being angry at work, it's like being angry that your work uniform is made by one textiles vendor not the other.

You get to choose what you use at home in your own time. If you feel good using Linux then, do it!

Yeah but veeam doesn't support fast block cloning which means you don't need to ever recopy blocks that don't change. From a performance point of view, fast block cloning gives incredible speed up so that in turn means more backups happen in a short time. That's pretty important even at our small business scale. I guess larger veeam service providers solve things differently.

I'll give you one reason it's used commercially: Veeam can only use xfs or refs as a deduplication enabled store using fastclone. For example I have a 60 disk nas hosting hundreds of customer backups and a petabyte. Without deduplication imagine how many extra petabytes of storage would be consumed. Each backup is basically the same image as well as the backup processing time.

Maybe they'll get that same feature on zfs one day.

Unless you want me to use refs? But I have tried that, and I've lost a whole volume to iscsi volume mounted to windows and formatted refs due to corruption when a network power loss happened gradually and whatever reason, that network interruption caused the whole volume to be unmountable over iscsi ever again. I'm not keen to retry that.

Xfs is pretty good with 60 disks, I wouldn't trust ext4 with that many but there's nothing factual about ext4 but a feeling.

About to get a second 60 disk nas for another datacentre for the same setup as above to migrate away from Wasabi as offsite. Will build xfs again. Looking forward to it.
