I don't know what Docker Desktop is doing but on a top end i9 with 128gb of ram it still takes 60 seconds to start
and the UI takes forever to do anything
it makes Teams look responsive
A lot of delays has to do with starting VMs. You need this for Linux on Mac/Windows.
Disclaimer: I started Rancher Desktop. I might be biased.

Sorry for using this comment as a way to get ahold of you but there is no DM function on HN and the comment I was wondering about was posted by you 18 days ago and the comments are locked now.
Here is the comment in question: https://news.ycombinator.com/item?id=33347058
I have been controlling my water heater with HA for a few months and I too am risk averse when it comes to legionella. You have taken it to another level by replacing the sensor inside with a DS18B20. I was also interested in doing this but I don't really want to drill into it. How did you install the sensor? Is the water not under pressure? I've just measured water temperature at the tap with a meat thermometer and under flow into a container to determine that the temperature falls in the range that is safe for legionella growth. Would love to look into a proper sensor again if you have any information about that.
Again, sorry for hijacking your completely unrelated comment.
First of all, I'm also concerned by legionella growth. However all the sources I can find suggests that at a legionella run above 60 degrees celsius once a week should be enough to kill all bacteria. So that's what I'm doing.
My sensor installation was extremely easy. My warm water heater is in fact a barrel within a barrel. And some insulation material between those barrels. If it would only be metal, you lose too much heat. In the outside barrel (excuse me for lack of a better term) there was an analogue thermometer. This thermometer has a metal back so it makes direct contact with the inside barrel. I just pulled this one out and replaced it with a DS18B20 probe. Again metal against metal, so maximum contact.
Finally I have calibrated the sensor by running it with hot water at the tap and measuring the temperature both there and on the warm water heater (with 2 DS18B20). I've done this for several temperatures with intervals of 10 degrees. I've ignored possible sensor deviations. Finally I used Excel's INTERCEPT and SLOPE functions on the range to calculate the value needed for a linear equation. I have used the formula:
boiler_temperature * SLOPE + INTERCEPT
I've also added my personal page to the 'About me' on here, and I have the same Reddit username if you want to DM me there.
Currently at 220 in one window, 350 in another, and eight in a third.
This is where those extensions (or native Firefox) is good for auto-sleeping tabs you haven't looked at in the last 10-20min. Saves so much CPU.
This is considered good?

"Docker Desktop on Linux runs a Virtual Machine (VM) so creates and uses a custom docker context desktop-linux on startup." I had previously assumed it would be native on Linux, but apparently not. To be clear, this only applies when talking about "Docker Desktop" installations - not the same thing as "docker" etc etc.
I also think the performance is pretty bad, and I've used it on all three OSes at one time or another. I simply never install "Docker Desktop" on Linux typically anyway - it adds so little value over a basic native local docker install there.
The only thing I think "Docker Desktop" is really great at is creating FUD regarding using the alternatives or even plain ole free "docker", but that is probably its primary means of generating revenue for the company - I've seen docker desktop licences get deployed everywhere recently, regardless of the merits. So many users I encounter don't even understand the distinction now between docker/docker-desktop, or that there is one.
Also, there are many people who want that VM boundary. We found this when designing for Linux in Rancher Desktop and talking with people about it.
I actually decided today to stop using DD on my Windows machine and just run docker native inside the WSL2 VM instance instead. Still not sure what solution I'm going for on my Mac.
The initial setup was a little more complex than just running Docker Desktop, but since then, it's running flawlessly.
Also known as a VM, but maybe you get better warm up times. My main complaints are with the "docker desktop" app experience - not so much "docker" itself VM or otherwise. It adds so little to docker for the license cost too, at least so far.

You can simply install docker in a VM/WSL2 natively yourself and avoid docker desktop/licensing altogether. "Docker Desktop" is/was really a tool to simplify getting a Linux Kernel (the critical dependency for cross-platform container dev) on non-Linux platforms IMO, which seems wild to pay for to me in its current state and when Windows has a great built in VM via WSL2 anyway. That it even exists on Linux now (recent addition) is kinda amusing - on MacOS and Windows there is at least some argument to be made it simplifies getting the kernel...
