Hey all,

My personal home-hosted server ran out of disk space and so went offline while I was away and I didn't notice it for a week or two.

This meant that federation requests (or subscriptions requests) went offline and now most of the servers I'm federated with are lagging. I'm only getting updates from a couple.

Is there a way to trigger federated servers back to life so I get the subscription updates? Federation does seem to be working, given some servers seem to federate fine and this post was via federation and has worked.

Hey,

On my local lemmy I noticed that after trying out Tailscale I borked my federation connectivity (at least I think that was it).

I've rolled back changes, but noticed that most of my federation updates aren't flowing, and I can't even subscribe to a local community.

However, I can subscribe to a remote one, but only one of quite a few I was previously connected to.

No errors in the logs, and everything seems to be working otherwise.

Any ideas of where to search?

That pending: 1 never clears. Not sure how to identify it.

This was posted through federation, from my local instance - so, obviously bits and pieces are working just fine.

Last time my dishwasher died I just had to take it had and clean the pump underneath. Basically the connections apart under and had to just scrub them out. One tiny bit of plastic was gumming it up, causing some checks to fail. Stopped it running.

They’re surprisingly simple machines.

For Samsung I always buy the extended warranty. For our washer and dryer Assurion must have spent a fortune keeping them running. A lot more than I ever did to guy them. They’re only 8 years old too. It’s sad, but for Samsung they work nicely but fail frequently,

For your next one but Bosche. They’re all good, get a base model and it’ll clean well and reliably.

“For example, if you send a message from Beeper to a friend on WhatsApp, the message is encrypted on your Beeper client, sent to the Beeper web service, which decrypts and re-encrypts the message with WhatsApp's proprietary encryption protocol.”

So, not really end to end for most common use-cases.

I really don’t like the “but otherwise we’d need a warrant” approach.

Yes, of course you should need a warrant. That’s the bit that’s the safeguard and actually is the checks and balance against abuse. It’s not a problem to be optimized away.

Sounds like you need bevel gears.

I’m with Gordon though. It’s easier to move the fitting than rig up gearing.

I’ve done this for years, but also:

  • anything automated goes straight to specific folders for those categories. Very quickly identify stuff that’s noise and put in rules to move it out of your inbox. Sure some stuff you might need, but anything that’s corporate spam needs automating away.
  • use (and create if necessary) the right mail groups so your whole team, project partners, whoever see the right emails and ask people to use them.
  • add a VIP rule to highlight emails from the boss, VP, anyone you know you want to read right away
  • be clear with people on how to reach you. If you prefer Slack for immediate stuff, tell people. It’s fine to be clear that email is for less immediate consumption, or non-conversational stuff. Slack is far better for collab.

Most towers will fit 4 drives.

If you’re out of SATA ports or M2s you can buy PCI adapters.

If you’re buying SSDs they’re small and don’t care about orientation, can but plugged into the cables and stuffed anywhere in the case that doesn’t impede airflow.

Where do you want your drives? What sort of drives? I’ve also found it more performant to stuff them in the case and 4 drives isn’t a stretch unless you’re also running a ton in the target server.

Fastmail.

But, it’s not the cheapest. $5 a month gets what you need though.

Really quick WebUI, great features, including hosting your own domains and smtp rewriting.

Very smart helpful support team.

Great for degoogling.

The major email providers will only handle email from know good and trusted IPs. If you’ve been hosting on the same IP for 15 years you’re trusted. If you started it last night your IP is still untrusted. It takes a long time to gain trust.

SendGrid has a good explanation here: https://sendgrid.com/resource/email-guide-ip-warm-up/

Moving to Caseta for lighting from the random mix of bulbs which never quite work was amazing. It's also much cheaper to put in one controllable switch than replace the 6 bulbs in the light fittings connected to the wall switch. Those bulbs always fail in weird and non-debuggable ways.

I use Crafty Controller (https://craftycontrol.com/) to manage the minecraft servers. It runs in a docker instance and gives you a nice web UI to manage each minecraft server. I use it to delegate control to my kids to create and manage servers as necessary.

Finally, if you're not using a config mgmt tool, I'd start looking, so you can make everything easily re-doable. Personally I'm using Ansible, but puppet, chef, salt, etc all work too. Ansible is easiest given it does need it's own infra. I like it so if something dies I can redeploy everything onto a different server.

I've had a lot of success with a QOTOM box from aliexpress.

They're little fanless boxes running basic intel Core chips, in a variety of configs.

I've run OPNSense and PFSense as routers (also doing wireguard, torrents, etc), as well as just standard Ubuntu server.

Very small and low power, and pretty cheap. They come in a variety of configs.
