(#m6xngra) @prologic@twtxt.net I’ve tcpdump’ed and wireshark’ed the shit out of this. 😂 It’s not very helpful. I’d need to gain insight into the decision making of the switch itself. Why does it drop certain packets? That’s almost impossible to find out (unless it happens to be included in the switch’s logs, which it usually isn’t).

Like @mutefall@twtxt.net said, it’s usually some kind of misconfiguration. Hence you begin to dump the entire switch config into a file and then run diff against the config of a working switch. 🤣 Sometimes this approach works, sometimes it doesn’t …

We recently changed from Cisco to MikroTik switches. At least those switches offer some kind of basic API, which means we can configure them via our config management – instead of using the switch’s web UI or SSH, like some cave men. That should make our life much easier.

Honestly, all the switches I’ve seen so far were total crap. So far, MikroTik is the best thing. Maybe there are actually good switches out there, but they probably cost a ton of money, and we can’t afford that.

(#m6xngra) spooky action at a distance. Just remember all computing infra is rocks smashed together in a particular way to move sparkys around in the right statistical modal.

(#m6xngra) @prologic@twtxt.net In this particular case: Figuring out why a switch decided not to forward ARP broadcasts to certain switch ports. Like, you connect two devices to the switch ports 3 and 4 and they can ping each other – but when you move one of them to port 5, no ping anymore. So, rather low-level stuff.

Or, we have another switch that intermittently doesn’t respond on its management IP anymore (even when you connect your laptop directly to the switch with no other networking hardware in between). I still haven’t figured out this issue.

Might be a bit before I can update this Pod, not because of any issue with yarnd, but because, I think, my SD card must be dying in the RPi 🙃
Getting lots of file corruption errors, the thing can’t even download update archives from apt without them becoming corrupted or incomplete lol.

Spent the last few days debugging network issues at work.

Exhausting. You never get a full picture. You poke a little here, poke a little there, … Form a hypothesis and test it. Eventually, maybe, you can narrow it down a bit to some segment or even some component.

A very time consuming process. Even more so if you try not to cause downtimes for your users.

I want a magical device that allows me to look inside a cable/fibre.

But hey, at least we got rid of a bunch of Cisco switches in the process. So there’s that.

Conclusion: Is there anybody out there?

I’m not one for conspiracy theories, but it’s hard not to think that there is some truth to The Dead Internet Theory, i.e. the belief that the Internet is now empty and devoid of real people, and that everything is just bots talking to bots to generate content and clicks in order to get a share of the all-important and ever-growing advertising revenue5.

(#zo4ivxa) @marado@twtxt.net GPT-3 summarizes this as:

The European Parliament has passed a resolution on Artificial Intelligence with a majority of 495 votes in favor, 34 against, and 102 abstentions. The resolution includes many references to the advantages of Free Software and the FSFE is urging the Parliament to transfer its own position into the AI regulation.

Is this accurate? Is there a bit more to this? 🤔

Lining up the stud with a metal stud post, the fibro is out a little because the wooden stud is bowed out 3mm, so using a jig, and beam lever idea, I squeeze on the metal post as well and the wooden stud and push the wooden stud back to make space for the fibro joint.

Making stud walls, using 6mm rod rather than 4” nails, but the frame is not quite square. So I use a windlass tension-er to pull the diagonals squeezing the frame into a different angle. It worked a treat.
