Hi all - please tell me if I'm doing this wrong:

My 12yo spends all day on YouTube shorts. I want to block it, but can only block YouTube entirely. Blocking for everyone would upset my 15yo, so I need per-client domain filtering.

That was easy on Pi-hole. But my Raspberry died and I heard praise for Adguard Home so now I run that as a Docker container.

1. I can't figure out how to block YouTube for only some devices. Is that not possible with Adguard? Claude gives me complicated nonsense; you can easily do better.

I want to ditch Adguard and go back to Pihole. The caveat is that I must let Pihole run the DHCP server, in order to get correct per-client blocking. That's a pity, as I have a neat UniFi network set up.

2. Can I get Pihole's per-client blocking without Pihole as DHCP?

I don't mind setting it all up in Pihole again (as yet another container) because I know it works (it's how I had it before the Raspberry died). But I would love to know if I am going about this the wrong way? Thank you!

I am selfhosting a lot of stuff, but some things are on good old DreamHost instead, for reasons of reliability and such. I'm sure many of you are in a similar position.

I've been extremely happy with DreamHost since ~28 years but various reasons prompt me to look for EU options. I am not looking for just plain stupid webhosting (not VPS) but the options I see are so limited: limited subdomains, limited mailboxes, limited databases, limited everything. DH has always offered "unlimited everything" for a few dollars per month, that's an insanely good offering.

Still, if you could recommend a good EU webhosting provider, what would you say?

I've made a large number of custom prints, and all of them were created using TinkerCad. It's an amazing toolkit, stupid easy to use but versatile. That is ... until something needs a tiny adjustment somewhere. That's when I feel it would've been neat to use parametric CAD instead.

I have spent many hours following Youtube tutorials for Onshape, Fusion, and FreeCAD. Tutorial shapes like a LEGO brick are fairly easy, although I admit that this kind of modeling is a sharp departure from the kid-friendly TinkerCad.

My problem is that I don't want to make simple coasters or keychains, but complex shapes like this one. It's a holder/mount for two different kinds of walkie-talkies that I use, and the blue part slides into a tray in my car's dash where it sits nice and snug.

Question: How the hell do I even get started modeling something like this?? There's not a single straight cuboid here. Everything is slightly wedge-shaped.

The way I do this in TinkerCad is that I build the hollow first: I made a 3d model of the walkie, a little oversized, set it be hollow, and drop it into the shape - that's the red or orange shells you see.

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?

edit: solved by printing at 20% of regular speed. This seems to give the filament enough time to ooze out of the nozzle, and the print result was excellent.

My Prusa MINI+ works like a charm, except with TPU. We have a 5-hour print task that starts well but fails after 2-3 hours because the TPU filament is no longer being pushed into the nozzle; instead it comes out of the extruder!

What could be causing this? Is the TPU just too soft and bendy? Is the shape of the extruder housing at fault?

It looks as if the TPU gets stuck and is then pushed into the extruder housing when the extruder continues to push. This happens again and again, but it's weird that it works well for hours before failing. The object is basically just a long block, so absolutely straightforward and no retractions.

We have checked that the nozzle is clean and has no obstructions. We have opened the extruder every time it happens, and there's no obvious problem to see (see photo 2 here).

We are considering to print a new lid for the extruder housing, see photo 3 here: (1) is the exit hole, and (2) is the cavity where the TPU ends up so it might help to change the lid (3) to a shape that does not leave a cavity there. Or is the problem that the roller (4) is too narrow or too soft?

For reference, the filament is Tinmorry black TPU from Amazon.

This is a Prusa MINI+ that has worked flawlessly for 3 months. Suddenly the prints won't stick to the bed, the first layer is all messy and I cancel the print before anything worse happens.

• The printer has auto bed leveling so I would rule that out.
• The plate is cleaned with 70% IPA, so it's not dirty either.
• I have tried to adjust the "Live Z Adjust" while printing that first layer, but no setting works well.
• Each filament is printed at recommended temps (+/- 215C) and bed is at 60C.
• Out of my 5 spools, only 1 works well: RepRapper 3-color PLA. Even the Prusament PLA fails to stick well, and also eSun PLA+, and eSun matte PLA, and Tinmorry TPU.

Update:

• Thank you all for your kind input.
• I washed the plate, and cleaned the nozzle (have no spare nozzle).
• I also did a fresh Z-test (with this object) using Prusament galaxy silver PLA.
• That was successful and showed that my height was already very close to perfect.
• Z-test result shows that -1.425 is best. I was off by only 0.025. Image
• Started printing an object with eSun matte black PLA but the result was same as in my original photo.
• Changed back to the Prusament galaxy silver PLA and the result is perfect. (image)

So it looks like my filament storage is not up to snuff! Good thing that I only have a few spools, so not much is lost.

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?
