The worst part of today was me bloodying myself pulling the cover off an Enphase 5P battery, thinking I needed the cover removed to get at a DC cut-off switch. I did not need to remove the cover.

Ripped a fingernail clean off.

FROM MY PINKY FINGER.

Nice, so today a brownout at the new house just built blew up the main part of my solar gear. The Neutral Forming Transformer relays fused on.

So now my house is bypassing the solar gear. Otherwise I wouldn't have power once batteries ran out.

@tracketpacer

My wild guess today now knowing a tiny bit more about electricity is that the vampire tap basically created a stub that caused reflections that fucks up signal integrity, and when you actually connect the monitoring interfaces to another NIC, the monitoring NIC actually consumes the reflection.

@tracketpacer hey, along the lines of "old ethernet tech" did you ever make a 10/100 ethernet vampire tap out of four keystone jacks and one length of cat5? I know they don't work with 1G ethernet (see @mossmann's throwing star LAN tap that had capacitors to knock the speed down to 100mbit)

One thing I always was curious about them was: why won't it !@#$ing work if you don't have the "monitor" interfaces connected?

How long until the #curl project yet again gets a letter from the US federal government "Please report how you are complying with these new US Federal government requirements" when curl isn't a vendor and is open source

Awesome. So I know I have sinus polyups (that swell and blocks off my olfactory bulb) that kill my sense of smell, but my maxillary sinuses are pretty clear.

I can't tell if I've got covid-19 loss of smell/taste or what. All I can taste is salt.

Apparently USPS gave up last night (due to snow/being overworked) and decided to fake that I requested them hold a package at the post office.

Either twitter broke 2FA, or has stooped to a new low in trying to keep account numbers high by preventing people from logging in.

I was going to delete my account after nuking all my tweets and removing followers/following

Trying to figure out just how much damage has occurred due to a misunderstanding sucks.

TIL: my tiny 8 port netgear PoE switches I otherwise have been using to power SIP phones and raspis only supports the 15w version of PoE and now I'm really frustrated how vendors on amazon/newegg/etc use "PoE+" to mean both 802.3af and 802.3at.

Wait, why are mortgage rates going up if the FED SOFR rate is going down?!

Okay, these can't be as awesome as I think they're going to be for "I forgot to run enough CAT5 wires in the wall" can they? As long as I have a PoE switch upstream, I can turn one wire into 4 without futzing with additional power at the other end.

Also trying to figure out if I want to drop one or two of these inside walls or not.

Hey #networking nerds out there: I think there are "link" cables out there that are basically integrated SFP<-->SFP form factor, is it possible to link two network switches together with those, bypassing the need of SFP adapter<->(some fiber/copper)<->SFP adapter?

I'm basically looking to trunk different model switches together.

soon we'll get the remote metering kit, so the span panel knows about battery and solar.

Now that I know it wants to display grid (consumed?), solar production and battery charge/discharge I think I know how I'll ask the electrician to wire up the remote metering kit.

Nice, the electrician wired up the span panels yesterday exactly how I wanted them, and now I can remotely(!) monitor it, since I also got Internet working at the house. The future is cool.
