I'm looking for Arduino discussions and there's plenty on Reddit but almost dead silence here.

Is this all there is?

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!

Hi all! My very old Mitsubishi Pajero III (V60 from 2000) got a 2" lift kit and now the rear wheels have too much toe-out. The stock tie rods won't adjust far enough and there are no other original "sizes."

So I need some aftermarket tie rods for the rear axle. My own research tells me I need a shorter (longer?) version of the original part number MR508134 (Imgur).

Two questions:

• Am I correct that the rear toe angle is adjusted via this part?
• Given that the stock MR508134 is no sufficiently adjustable, what sort of aftermarket part should I be looking for? I'm in Europe.

(For the sake of completeness: the front tie rods have adequate adjustment range.)

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.

Printing here with eSun PLA at 215 C on a Prusa Mini, and there are lots of hairline strings.

What's causing those strings? Temp too low?

TLDR = what's a good next step after kid-friendly 3d creation tools?
Solved = Fusion360 is voted as winner, we even got a nice tutorial playlist.

Hi all - I'm still very much a new user. Highly skilled in IT but just getting my feet wet in 3D printing, since a month or so. I love the possibilities! I can physically create anything I can image, it's amazing.

So far, I've used mostly TinkerCad and done lots with it. The learning curve is practically non-existent, and it has sufficient features to do a lot.

But of course it's not perfect. Obvious example: can't do fillets, except in roundabout ways using negative blocks.

I've tried OnShape, OpenScad, Fusion 360, but found them quite a steep hill to climb.

Are these good choices, or is there something in-between that would make it easier for me to advance?

Here's a part of a cabinet in my wardrobe where my printer lives. It's a bit noisy with all those hard surfaces so I am just about to put up some foam padding on all 5 sides.

Is that stupidly dangerous?

You can see I have a smoke alarm there, but it won't stop a fire on its own.

Edit: the cabinet has no door, it's always open like in the photo, but the wardrobe door is generally closed. The room has some ventilation so smells do go away.

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.
