There's so much spam, and people diligently downvote. But the posts are still shown, with -53 votes or something.

When a post is clearly unwanted, could it be hidden?

I run an old desktop mainboard as my homelab server. It runs Ubuntu smoothly at loads between 0.2 and 3 (whatever unit that is).

Problem:
Occasionally, the CPU load skyrockets above 400 (yes really), making the machine totally unresponsive. The only solution is the reset button.

Solution:

• I haven't found what the cause might be, but I think that a reboot every few days would prevent it from ever happening. That could be done easily with a crontab line.
• alternatively, I would like to have some dead-simple script running in the background that simply looks at the CPU load and executes a reboot when the load climbs over a given threshold.

--> How could such a cpu-load-triggered reboot be implemented?

edit: I asked ChatGPT to help me create a script that is started by crontab every X minutes. The script has a kill-threshold that does a kill-9 on the top process, and a higher reboot-threshold that ... reboots the machine. before doing either, or none of these, it will write a log line. I hope this will keep my system running, and I will review the log file to see how it fares. Or, it might inexplicable break my system. Fun!

TLDR: VPN-newbie wants to learn how to set up and use VPN.

What I have:

Currently, many of my selfhosted services are publicly available via my domain name. I am aware that it is safer to keep things closed, and use VPN to access -- but I don't know how that works.

• domain name mapped via Cloudflare > static WAN IP > ISP modem > Ubiquity USG3 gateway > Linux server and Raspberry Pi.
• 80,443 fowarded to Nginx Proxy Manager; everything else closed.
• Linux server running Docker and several containers: NPM, Portainer, Paperless, Gitea, Mattermost, Immich, etc.
• Raspberry Pi running Pi-hole as DNS server for LAN clients.
• Synology NAS as network storage.

What I want:

• access services from WAN via Android phone.
• access services from WAN via laptop.
• maybe still keep some things public?
• noob-friendly solution: needs to be easy to "grok" and easy to maintain when services change.

I have some jet lighters in my shop. I'm not a smoker but they are useful for other things too. My problem is that they seem to not work at all?

When I buy them they are fine, push the button, clear "click" sound and a fine hot jet of fire. After a while though, they simply won't fire anymore, even though the little window shows that there's plenty of gas inside.

Are these also using the normal propane/butane as regular lighters?

Let's say I never want to see another post about Trump, or NFL, or Apple, or that weird "rule" thing.

Is there presently any way to filter that out? In Lemmy as a whole? Or inside the Voyager app?

I am looking for an action cam. It does not need to be a GoPro or DJI simply because they are so very expensive -- but finding alternatives is difficult, mostly because all those products are misrepresented on sites like Amazon. Some reviews reveal that the manufacturer offers free add-ons to customers who post 5-star reviews. That means I cannot trust any review at all.

Where can I find honest reviews? How can I choose a decent action cam without getting scammed?

Background:

• At work we use MS Office, because who doesn't. We used to have a central file server with lots of well sorted directories.
• Then Corporate decided to ditch that, everything must move into OneDrive so there's always a Data Owner.
• The local boss had to move everything from the network share into his own OneDrive, and then share, with each of us, the folders that were relevant to each of us.
• This sounds like distributed storage, which is probably smart in some way.

In reality, it's shit. Everything is now a link to "corporateName.sharepoint.com" in the browser, and it's a hassle to find that in the file explorer. SOmeone just shared a folder with me. I see it in my browser. How do I get it from the browser into a normal folder view? Should I forget about on-disk storage; is everything today just a browser bookmark?

Worse, I have no idea what's where. Some people share some stuff and somehow it ends up in my OneDrive, but what's the context of it?

This seems so wrong to me. Am I just not "getting" it??

Neighborhood cats shit right in the middle of my lawn. It stinks and the robot lawn mover makes it even worse.

I do NOT like cats, and this is not helping.

What works to keep them from shitting on my lawn?

The votes have spoken. Some people are cat lovers; thanks for the great advice from the rest of you! I will not go out of my way to accommodate other people's pets that aren't welcome on my property. My first weapon of choice will be chili because it's simple and cheap. Other ideas have been noted.

On Windows, we've had the defrag tool and others, that happily works on a drive even while it is in use, even the OS disk.

On Linux, I know of the fsck command but that requires the drive in question to be unmounted. Not great when you want to check a running server. I do not want to stop my server and boot it from USB, just to run a disk check. I can't imagine that's what the data centers are doing, either!

Surely some Linux tool exists that can do some basic checks on a running system?

I mean, the simplest answer is to lay a new cable, and that is definitely what I am going to do - that's not my question.

But this is a long run, and it would be neat if I could salvage some of that cable. How can I discover where the cable is damaged?

One stupid solution would be to halve the cable and crimp each end, and then test each new cable. Repeat iteratively. I would end up with a few broken cables and a bunch of tested cables, but they might be short.

How do the pro's do this? (Short of throwing the whole thing away!)

Prove me wrong, please?

edit: thanks for all the great comments, this is really helpful. My main take-away is that it does work, but requires dry air. In humid conditions it doesn't really do anything.

Spouse bought this thing that claims to cool the air by blowing across some moist pads. It's about as large as a toaster, and it has a small water tank on the side. The water drips onto the bottom of the device, where it is soaked up by a sort of filter. A fan blows air through the filter.

1. Spouse insists that the AIR gets cooled by evaporation.
2. I say the FILTER gets cooled by evaporation.
3. Spouse says the cooled filter then cools the air, so it works.
4. I say the evaporation pulls heat (and water) from the filter, so the output is actually air that is both warmer and wetter than the input air. That's not A/C, that's a sauna. (Let's ignore the microscopic amount of heat generated by the cheap Chinese fan.)

By my reckoning, the only way to cool a ROOM is to transport the heat outside. This does not do that.

We can cool OURSELVES by letting a regular fan blow on us = WE are the moist filter, and the evaporation of our sweat cools us. One could argue that the slightly more humid air from this device has a better heat transfer capacity than drier air, but still, it is easier to sweat away heat in dry air than in humid air.

Am I crazy? I welcome your judgment!
