  • Yeah, I think in this case there’s a lot more tiny conductors sharing what can add up to pretty high current loads on PD connections. Adding extra connectors adding resistance to low (5-20v) voltage high current connections is adding an extra failure point and increasing resistance on the whole cable run.

    Not inherently unsafe, but just not a good idea to promote because you know someone will try to run a 200w charging cable for 30m with like 5 connected cables.


  • I think a lot of people are mostly on the money here. It’s to do with resistance. Now, I’m not a qualified electrician, but I’m an amateur radio license holder and a lot of what you learn for that is applicable here.

    The main problem as many have said is resistance. This comes about from both the length of the conductors but also from every plug/socket connection adds resistance. Also in the case of the non extension socket multipliers, as you add more the weight bearing down would also likely start to make the connections less secure causing more resistance and possibly adding to the problem through arcing.

    Now the resistance alone on small loads likely wouldn’t be a huge problem. But if you had a large enough load (specifically at the end of the stacked connectors/extensions), or a fault that caused a larger than expected load the current would cause the resistance to generate heat.

    There’s a lot of ifs and maybes involved, but really why do it? There’s really no real world situation to need to have a dangerous amount of extensions like this though.

    For larger loads here in the UK there’s some very specific other concerns when dealing with ring mains. But really you’d need to do really weird/unusual things for that to become a problem.





  • This is something I do on my new (Samsung) phones for the last 2 phones and this latest one I also turned off fast charging. On previous phones it was capped at 85%, current ones seem to have several options with the highest “saving” being to charge to 80%

    If I’m going out for the day and need the full charge I turn it off for the duration and if I need a fast charge I turn that back on.

    By and large though most of the time I keep it off. Seems to make the batteries last a bit longer. Too early to tell on the current phone though. Only a year old. I generally keep phones for around 4 years.

    I used to do the opposite on the old nicad batteries phones had in the 90s. I’d carry a spare fully charged one, run the main one down to zero, swap them and then charge it to full. This made a huuuuge difference though.



  • We can see it ourselves. We use rabbitmq for incoming (and maybe outgoing, it’s been a while since I looked at how it is) federation. So, you can see the queues there. For incoming (from rabbitmq) and outgoing there are also queues (symfony messenger) and these handle failures and can be configured and can be queried.

    After the upgrade I just took the default configuration again (because it seems queue names changed). But I used to have various rules setup in rabbitmq for retries and it took a fair few tries before the messages ended up in the proper “failed” queue (which needs manual action to retry). Some items you eventually need to clear (instances that just shutdown, or instances that lost their domain for example). They will never complete.

    But it’s not exposed in any way to my knowledge. Well unless people have their rabbitmq web interface open and without login of course.





  • Looking at incoming request. .world is working OK for me. They seem to be batching stuff like I’ll get nothing for 30 seconds, then over 3 seconds like 50+ requests.

    Of course I don’t know if their queue is backed up and I’m getting delayed stuff. I’d need to stop processing and look into the incoming queue to see what they’re sending.

    Bit of an edit. Looking at incoming again I can see under newest items, an entry from world that was 11 minutes old. Oh I have an idea. I’ll see if this edit gets there in a timely manner.

    Spoiler alert, it was instant.

    Oh ignore me. It’s specifically between those two instances I guess.



  • I did a routine upgrade on my mbin server, where I had an old version with changes I made myself.

    Well turns out I upgraded something (probably redis) that broke symfony that broke everything.

    So I had a fun afternoon upgrading to the latest mbin version. I mean I needed to anyway but my hand was forced.

    Yep sometimes an innocent looking update will change your weekend plans.

    Anyways, any reason not to use ssh?
