I turn it off every night or if I'm away for many hours, so about 10 minutes right now.

I do have a Raspberry Pi that's been up 12 weeks, 5 days, 19 hours, 59 minutes. I believe there was a planned power outage when it was lasted turned off.

I reboot mine when I'm bored

Only a few days, maybe 12 if I had to guess. Im running with memory overcommit disabled and building a rust project with vscode and Firefox open will hang the kernel eventually. I caved to the kernel's expectations and set up a swap partition but it still dies.

I should say it's been on for probably 2 years straight ignoring reboots

I had about 300 days of uptime on my server but I did some hardware maintenance recently. I'm back up to like 20 but I need to do more stuff.

I did find a fun "bug" the other day with windows and how it tracks uptime. Since shutting down hibernates the kernel it doesn't treat it as time off. So when I fired up this surface I hadn't used in a long time it had 180 days of uptime.

Last time it was off was during the summer holidays.

Thanks to Mint's updates... about 10 minutes.

My main PC only stays on for a couple days at a time (on sleep/hibernate when not in use) only because I'm generally too lazy to shut all programs down. I reboot on updates though, which is every couple days.

55 days, 34 mins

Edit: my Mac mini (the torrent client) is 199 days.

I have all my devices set to reboot once weekly a few hours after daily scheduled updates. I probably don't need to do this, but I do. It's a habit I got in with scheduling router reboots, and then started extending it to other devices. It's nice to have some solid uptime, but I have three unbound DNS servers in sequence so they update and reboot on a staggered schedule so it's like they never go down.

You never know when the odd cosmic ray is gonna hit and flip yer bits.

As of today about 10 years not counting the odd driver restart

I'm surprised how many people turn their computers off. My desktop uptime is 4 day, but, I do put it to sleep at night (which I think counts towards its uptime).

I will look into hibernating. The reason I don't shut down is because I usually end up with carefully placed windows and lots of ongoing projects all over. Restarting would mean I'd have to start all that up again - assuming I remember what I was doing.

I have a drive that's roughly 13 years old, and has around 11 years 80 days of power on time if that says how much my computer is on.

I only restart it when windows updates start fucking with my networking or my audio drives entirely shit the bed.

I never turn it off it gets an occasional reset when updates need to be installed but that's about it

34 days without booting? Are you using a Debian system and don't update often? You should, for security patches at least. I'm on an Arch based system and update every day. Sometimes there are updates that require a reboot, so all services are up to date. My system is often up for a few days, sometimes even for a week.

Small tip, logging out and in will have a semi clean environment without a full boot. That means the uptime won't reset.
