I was talking about “Yundera”.
⁨Comment⁩ on ⁨What are your self–hosted alternatives for inter device communication?⁩ ⁨⁨1⁩ ⁨day⁩ ago⁩:
Is this a casaOS fork you need to sign up for, to get it installed? …Why?
⁨Comment⁩ on ⁨Cubieboard users abandoned? Trying to find support docs & software.⁩ ⁨⁨1⁩ ⁨week⁩ ago⁩:
Yeah, use Armbian. And Debian mainline and Arch Linux (ARM variant) run on the Cubietruck as well. Most of the stuff has been mainlined. I just can’t get graphics acceleration working. Other than that you could just install any regular Linux distribution. If you’re willing to put in the extra effort to deal with u-boot or whatever we use these days and the other effort involved to put Linux on an ARM computer. There’s info on their Wikis. And https://linux-sunxi.org has some information as well. Most of the times general instructions for A20 boards apply.

Maybe try a different bed temperature? And I got some improvement after cleaning the bed with alcohol.
⁨Comment⁩ on ⁨Sniffing WS2812 (Neopixel) bus?⁩ ⁨⁨1⁩ ⁨month⁩ ago⁩:
Not sure how easy it is to sample a digital signal that fast. The specs say it’s 350ns - 800ns. So my calculator says that’s about 3MHz. I don’t think noise etc will be an issue. And an opendrain input should be fine and not mess with the bus. You’ll likely have to find a good approach to read at that speed. Or find a suitable peripheral.

The correct tool might be an oscilloscope / logic analyzer.

But maybe have a look at some projects like “micro logic analyzer for RP2040”, seems it’s possible to sample digital signals up to 100MHz. There’s several projects like that out there. But I think the correct search term is “RP2040 logic analyzer”.

I don’t think a lot of people “sniff” some WS2812 bus. You can have a look at other project’s code to generate all sorts of effects.
⁨Comment⁩ on ⁨How to clean laptop?⁩ ⁨⁨1⁩ ⁨month⁩ ago⁩:
Yes. Thx, I forgot about that. Especially the insides. You probably want to have a look inside, if the outside already looks that dirty. And the case / outside is probably fine with some light zapping. It went through ESD testing and certification. And should be able to deal with electrostatic discharge in some way. But the (individual) components on the inside are way more delicate and not made to withstand it.
⁨Comment⁩ on ⁨How to clean laptop?⁩ ⁨⁨1⁩ ⁨month⁩ ago⁩:
Air blower, Q-Tip, Toothpick? And Isopropanol is the cleaning fluid of choice for electronics. I’ve also used my vacuum on Thinkpads before. But beware the vacuum. If anything is just tucked in, it’ll dislodge it and suck it in. And you get to spend the next 20min trying to find some tiny part in a pile of dust and hairballs.
⁨Comment⁩ on ⁨Buying a domain - WHOIS/PTR privacy?⁩ ⁨⁨2⁩ ⁨months⁩ ago⁩:
Latest changes in the EU are part of the NIS-2 directive. My private German domains don’t show a lot of detail and it’s been like that for many years.

Not sure if you broke out of the Matrix here. OP’s reply contained an em-dash, started with an affirmation. Follows the rule of three. I’d say there’s still a high likelihood it’s an AI which “claims” the code went through review.
⁨Comment⁩ on ⁨Hosting Dockerized website on VPS with Apache⁩ ⁨⁨2⁩ ⁨months⁩ ago⁩:
Yeah, You’ll have to do a lot more troubleshooting than this. Did Docker successfully bind to port 8000? Can you curl it from the VPS itself? Does the container and the things in it run properly? Are there any error messages?
⁨Comment⁩ on ⁨I built a local AI movie recommender for Radarr using Ollama⁩ ⁨⁨2⁩ ⁨months⁩ ago⁩:
Did you build it, though, or did Claude code it?
⁨Comment⁩ on ⁨I built a local AI movie recommender for Radarr using Ollama⁩ ⁨⁨2⁩ ⁨months⁩ ago⁩:
Yes. I think determinism a misunderstood concept. In computing, it means exact same input leads to always the same output. Could be 100% wrong, though. As long as it stays the same. There’s some benefit in introducing randomness to AI. But it can be run in an entirely deterministic way as well. Just depends on the settings. (It’s called “temperature”.)
⁨Comment⁩ on ⁨Self Hosting for Privacy - Importance of Owning your own Modem/Router?⁩ ⁨⁨2⁩ ⁨months⁩ ago⁩:
Interesting. Thanks for the info. I’ll re-think whether I recommend it to random people around the world, then.

In Germany it’s great. I’ve been using it for many years now. But we have some good hacker organizations, digital sovereignty and privacy groups, nonprofits and some generous IT companies. Maybe it’s random private individuals in other countries and they’re not that reliable.

Seems right now there’s something going wrong anyway. I don’t think the amount of “offline” servers is normal. And a good amount of them isn’t even offline, but still answers my DNS queries.
⁨Comment⁩ on ⁨netgoat reverse proxy – "seriously messed up code"⁩ ⁨⁨2⁩ ⁨months⁩ ago⁩:
After a few “Delete junk” commits, “Broken”, “PATCH: Hope this fixes it”, and “Basic Reverse-Proxy”, it’s now at version 1.0.1-alpha.1. Don’t know what they did to Git. But their “minor commit” touches almost the entire code in their repo.

100% wouldn’t use it.
⁨Comment⁩ on ⁨Self Hosting for Privacy - Importance of Owning your own Modem/Router?⁩ ⁨⁨2⁩ ⁨months⁩ ago⁩:
I don’t think you’re supposed to query Tier 1 servers as a client. I keep forgetting how DNS and recursive lookup works, but the Tier 2 servers would be what people connect to and who do the heavy lifting. The Tier 1 do the root, authoritative stuff and their custom TLDs.
⁨Comment⁩ on ⁨Self Hosting for Privacy - Importance of Owning your own Modem/Router?⁩ ⁨⁨2⁩ ⁨months⁩ ago⁩:
Isn’t it a global effort? According to what I see, they list a bunch of servers in all Europe, USA, Canada, Australia …Japan?
⁨Comment⁩ on ⁨Self Hosting for Privacy - Importance of Owning your own Modem/Router?⁩ ⁨⁨2⁩ ⁨months⁩ ago⁩:
I did one DNS query and it took 22 msec with the nearest OpenNIC server and 24 msec with Cloudflare’s 1.1.1.1 So dunno… roughly same responsiveness? For a proper answer we’d need to do more measurements, though.
⁨Comment⁩ on ⁨Self Hosting for Privacy - Importance of Owning your own Modem/Router?⁩ ⁨⁨2⁩ ⁨months⁩ ago⁩:
Even if you control your router/modem, they still control the other end, it connects to. So i think it depends a bit where you’re going with this. If you’re worried about them doing packet inspection, or logging IP numbers you connect to, I don’t think there’s a big difference. They could do it anywhere.

A router interfaces with your local network, though. So in theory a router can be used to connect to your internal devices and computers and maybe they have an open network share without password protection or something like that. But we’re talking violating your constitutional rights here. It’s highly illegal in most jurisdictions to enter your home and go through your stuff.

I’ll buy my own router because I can then configure it to my liking. And my ISP charges way too much for renting one. And what I also do is not use my ISP’s DNS service. That’d just send every domain name I open to their logfiles. Instead I use one from OpenNIC

Thanks for the link. As a short aside for the other people here: Try not to spam developers. That usually achieves the opposite and makes them miserable, when we want them to not burn out and write good software for us. A thumbs-up emoji is the correct reaction for the average person. Or a code-review highlighting specific issues in the code.
⁨Comment⁩ on ⁨Decorative LEDs not working⁩ ⁨⁨2⁩ ⁨months⁩ ago⁩:
Nice! 💪👍
⁨Comment⁩ on ⁨Decorative LEDs not working⁩ ⁨⁨2⁩ ⁨months⁩ ago⁩:
There’s some transparent varnish on these flimsy wires. That’s why they don’t short out. And probably also why they don’t make contact with your wires. You have to remove the coating at the ends. It’s usually done by temperature or sandpaper, I believe?
⁨Comment⁩ on ⁨New ntfy.sh v2.18.0 was written by AI⁩ ⁨⁨2⁩ ⁨months⁩ ago⁩:
Uh. I’d really prefer if people experimented with new technology a bit more cautiously and not directly jump to “the biggest release […] ever done”.
⁨Comment⁩ on ⁨What us the best way to add remote access to my servers?⁩ ⁨⁨2⁩ ⁨months⁩ ago⁩:
Hmmh. I’m not entirely satisfied with any of them. Crowdsec is a bit too complex and involved for my taste. And oftentimes there’s no good application config floating around on the internet. Whereas fail2ban is old and eats up way too much resources for what it’s doing. And all of it is a bit too error-prone(?) As far as I remember I had several instances when I thought I had set it up correctly, but it didn’t match anything. Or it was looking for some logfile per default but my program wrote to the SystemD journal. So nowadays, I’ll double-check everything.
⁨Comment⁩ on ⁨What us the best way to add remote access to my servers?⁩ ⁨⁨2⁩ ⁨months⁩ ago⁩:
I just enable SSH, configure it to run on some non-standard port and enable Fail2ban… Make sure if use a certificate or secure password and also check if fail2ban is actually doing its job. Never had any issues with that setup.
⁨Comment⁩ on ⁨MPV: The Ultimate Self-Hosted Media Solution You're Probably Sleeping On⁩ ⁨⁨6⁩ ⁨months⁩ ago⁩:
Btw, the proper place to mount filesystems is either /media or /mnt. I wouldn’t create a directory called /Volumes in Linux. And pay attention, these are case-sensitive and most (not all) system directories have agreed on using lower-case letters only.
⁨Comment⁩ on ⁨What is the current state of Matrix?⁩ ⁨⁨8⁩ ⁨months⁩ ago⁩:
I think judging something really depends on the requirements. No one said using technology was going to be simple and easy. We should make it as easy as we can do, but no more than that. There's still a lot of room for improvement. But in the end the commercial services are geared towards convenience. And they'll always outpace us. We have to set up servers and jump through a few hoops so it's us in control of the network. There is no other feasible way to do it.

Though I really wish we had some messenger that makes encryption foolproof. And rock solid, and with a resource footprint of IRC when concerned with text messages, but not limited to that.
⁨Comment⁩ on ⁨What is the current state of Matrix?⁩ ⁨⁨8⁩ ⁨months⁩ ago⁩:
We've had the discussion a while back here in selfhosted. You can find it here: https://awful.systems/post/5029223

Main points: Continued drama around people, and tuwunel is programmed by a single, (paid) developer and I figure once there's anything wrong with that, tuwunel might die instantly. While continuwuity is a community effort and maybe that's a bit more sustainable. Though I don't own any crystal ball and I don't know how things will turn out.
⁨Comment⁩ on ⁨What is the current state of Matrix?⁩ ⁨⁨8⁩ ⁨months⁩ ago⁩:
Sure, I believe that is supposed to be uWu or maybe some kind of puppy talk. It's certainly originally started by June, who turned conduit (which is a sane name) into conduwuit.

I figured I've lost all shame anyway, back when we discussed nerd topics in the school bus or the 5 'o clock train, like Linux lore, anime, Star Trek concepts and technobabble. I mean people were staring and I'm aware of that, but I've really lost all F*'s to give. And that turns me into the person who I am today, and I'll happily write sentences like the one above. Or still talk about Star Trek in a crowded train. And these days it's the mycelial network and that really makes people question my sanity. 🫠
⁨Comment⁩ on ⁨What is the current state of Matrix?⁩ ⁨⁨8⁩ ⁨months⁩ ago⁩:
If you want a conduwuit sucessor, I'd choose the continuwuity project over tuwunel. The legitimacy as the sucessor is mainly self-proclaimed, and continuwuity is a community effort. The entire thing is kind of a shitshow, though. If you want to do it like 99% of people, make friends with Synapse.

I think what you describe still holds true. You need a few correct DNS entries and an open port. Once you want VoIP, some more ports and a TURN server will become necessary. I didn't find it too hard. And I run continuwuity these days because Synapse wastes too much resources for what I do and their other efforts went nowhere. But I'm not sure about the future of those smaller Matrix server projects.
⁨Comment⁩ on ⁨[deleted]⁩ ⁨⁨1⁩ ⁨year⁩ ago⁩:
You can always ask the student body. If they're doing a good job, they're networked and know people and procedures. Sometimes the IT helpdesk people are knowledgeable and know who makes those kinds of decisions.

And I think server hosting and paying for that might work differently than in normal life. A university has quite some IT infrastructure. Maybe they have a free VPS to spare for things like that. Maybe it has to be super secure, intergrated into the single sign-on...
