  • Hank Hill, apparently.

    I don’t use Facebook and use all the ad blockers, but apparently I’m still tracked by IP.

    When my SO and I started dating, he hooked to my wifi one day and immediately started getting ads on Facebook for various lawn care products. He’d never had those come up before, lived in an apartment all his adult life, and has never searched for any kind of gardening supplies.

    I, on the other hand, do have a lawn that I take care of and frequently shop for various landscaping stuff. But he gets the ads for them.



  • Nice!

    I don’t have an EV (yet!) but the last couple of days have been fairly cool for July and haven’t had to run the A/C much. The house batteries ended up charging fully by about 2 in the afternoon. Since we can’t do net metering here, any excess is just wasted right now.

    When I do manage to get an EV in the next couple of years, I’d like to setup something similar to charge it when I’m producing an excess.

    (Hopefully this is OK for this community. Not news, but could be a nice highlight/discussion. If not, glad to find another spot to share it.)

    !solardiy@lemmy.world would probably love to hear about your setup.





  • Twice a year I fill in as DBA when our lady graybeard Oracle DBA takes vacation. This month is one of those times. Yay me.

    For my org, it’s just the massive in-house developed line-of-business application that’s tightly coupled to Oracle that keeps us chained to it. It’s technical debt from top to bottom, and has been accumulating steadily since the early 2010s, but no one seems willing to start replacing it.

    The new projects typically go with Postgres, MariaDB, or if all else fails, MSSQL. But the Oracle monster in the closet isn’t likely to leave any time soon.



  • The only tricky bit is forcing the Pi’s USB port into host mode by default. I thought the hub was defective but it worked when I put an OTG adapter into the micro USB port. The default auto detect behavior doesn’t work with this since it doesn’t connect to the OTG pin.

    I had to edit /boot/firmware/config.txt and add under the [all] section:

    [all]
    dtoverlay=dwc2,dr_mode=host
    










  • The usable south-facing roof area is full, unfortunately. I’ll have to do ground mount in the back yard and run a bunch of conduit if I want to add any more PV.

    The 32 kWh of batteries are made of two 16 kWh batteries in parallel. Since this system is in lieu of a backup generator, I have it configured to only draw the batteries down to 50%. That leaves the bottom 16 kWH available for emergency use. Basically, for day to day usage, I treat the battery as being half the capacity it really is.

    I’ve only been running this system for about 3 weeks now, but the batteries have been operating between 65% and 90% pretty consistently even running the A/C pretty heavily. They’ve been closer to low 60s this past week, but the wildfire smoke was choking out the sunlight Thursday and Friday.



  • Lol, def can become an obsession. First hand experience there.

    I’ve wanted a whole house PV system for a long time, and this is just me finally getting around to making it happen. SO and I were talking about getting a backup generator installed, but that would have been about $7,000 for something that would only get used two or three times a year since our power doesn’t go out often (we have no heat or ability to cook when the power goes out, and it’s always in the dead of winter when we lose power). The PV system I sketched out was about $9.000, but in addition to covering us during outages, we could use it daily to reduce electric bill so, unlike the generator, this would pay for itself over time.

    SO finally came around to my way of thinking, so here we are lol. My limiting factor is usable roof area. Of the roof that’s south facing, only about 14x20 feet of it is suitable for mounting panels. There’s a west-facing gable, but it’s blocked most of the time by a tree. The east-facing side of the gable is available, but it’s pretty much always foggy in the mornings here, so it wouldn’t add much to the system.

    Unless I build a ground mount setup in the back yard, we’re pretty much at the limit of how many panels I can buy. I’m kind of glad for that because otherwise I’d just keep buying them.
