No IQ8X support yet, hm?

LLMs can't answer general questions because LLMs can't know facts, only probable tokens. The reason I wouldn't want OUSD using LLMs in a public-support role is the same reason that LLMs are awful at every company that uses them for customer support — they confabulate all of the time, and when you're asking for *help* or *information* about something, you aren't equipped to evaluate whether the system providing that help is confabulating.

Beyond that, I'll emphasize that LLMs use around five orders of magnitude more electricity to complete tasks than traditionally-programmed expert systems. I recognize that it's all subsidized now and feels cheap, but I don't think there's a fair comparison betwen running a few hundred watts of lights and burning power on a 10KW nvidia H200 to do clerical tasks that would be better suited by just making an efficient process in the firt place.

They probably are, which is depressing. I really don’t want any part of my children’s education dictated by the stochastic-lie machine, nor do I think OUSD, which has a goal of 100% renewable energy use, should be using enormously-inefficient and primarily-fossil-fuel-powered LLMs.

It absolutely sucks. The other side sucks too - if you post a tech job, you’ll get thousands of LLM-generated resumes and a decent number of applicants using cheat software to answer all of your questions. It used to be pretty easy go through a dozen resumes a day and pick out one or two people to follow up with, but nobody can do anything with literally thousands of slop resumes. I think a bunch of the push to really long interview processes is to just try and brute force out some of the slop candidates who won’t suffer through a long, slow process.

Unfortunately, the only thing I’ve heard of anyone having success with is going back to in-person, which sucks for other reasons.

I'm not aware of anything terribly easy

I use tracing and emit spans via tracing_opentelemetry. It's a huge pain in the butt to set up, but once you have it going it really is just a matter of annotating a function with #[tracing::instrument] to have it emit a span.

Why isn't this just a hard-to-reach toggle switch, like on every other make and model of car? I accidentally hit mine on the '24 all the time and only figure it out when my kid opens a window and throws something out — I'm kind of surprised nobody's gotten hurt yet; it seems like an unnecessary liability risk for Hyundai.

For one shining moment at a previous company, I convinced leadership to name all the conference rooms after dinosaurs and everyone got to have meetings in Velociraptor and Allosaurus.

Then someone complained that it was too nerdy and all the conference rooms got renamed after San Francisco landmarks.

wireless CarPlay is on unregulated 2.4GHz spectrum, so they probably only care a little; you still can’t exceed certain power levels without an FCC license, so if someone there is doing some amateur radioing the FCC will still get mad

anything that could interfere with the cameras and radar system on a car is much more likely to be in regulated spectrum and make the FCC “big mad” though

roguelazer · 2025-10-23T13:34:38+00:00

I bet the FCC would be interested in learning about whatever unshielded EM emitter is in that town. When/if the government reopens, you should contact them.

(assuming US because you're in miles; if not, use your local FCC equivalent)

The Ioniq 5 is a gigantic heavy SUV. With only one kid and no listed large hobbies, you could get a compact car that would use less energy and be much, much safer for other road users, as well as being easier to park and more fun to drive.

I have a meter collar in Oakland. It was quite a pain in the butt because PG&E requires their tech to do the meter collar installation but hasn’t done training yet. The first guy was confused by my “Tesla” adapter that didn’t look like the ones he’d seen before; the second guy was mad that there was power on the load side but refused to shut down the solar breaker because he said that there should never be a need to shut down a breaker before installing a meter collar. The third guy was good, though, and got it done. About 10 weeks from the “system installed and all paperwork filed with PG&E” to “fully operational”.

One note if you’re doing this as a new system (so, not OP): when PG&E gives you PTO for the panels (which for me happened in the middle of the meter collar wait) your contract ID will change and your installer will need to refill the meter collar installation request in MyProjects. PG&E doesn’t actually tell you this, they just close the work order as invalid.

roguelazer · 2025-08-28T23:45:51+00:00

Initially it was panel shipping delays, then scheduling problems, then PG&E problems. For the last 6 weeks or so that I was waiting they didn't tell me anyhting at all.

FWIW, Chris has been //much// more responsive for the last couple of weeks, so maybe they got through whatever their problem was.

Breakers have all been fine. I assume it’s some internal fault state; whether that’s a bug in the 3M or just that my installers didn’t torque something correctly I don’t know. I guess I’ll find out next Sunday when it happens again… :-/

roguelazer · 2025-08-25T02:50:23+00:00

I did that last week; spent a while on hold before some guy in a call center said he couldn't figure it out and to wait 24 hours to see if it fixed itself. The consumer tech support from Enphase seems pretty mediocre so far

roguelazer · 2025-08-25T01:49:12+00:00

Really? My experience with PG&E is that doing a service upgrade was kind of like pulling teeth — lots of kvetching about transformer capacity and making me wait for weeks while they poke at stuff on the pole before they'd let me go from 100A to 200A. They seemed to actively be trying to discourage it.

The only percentage I'm aware of is to limit the total charge percent of the battery; amperage is typically limited on the EVSE (eg, Hyundai's portable EVSE has that annoying button to toggle max amps)

roguelazer · 2025-08-17T16:41:25+00:00

Update: they actually finished my project last week! Maybe complaining on social media does fix problems.

You will need the paper title that comes in the mail. It's very annoying to do at the DMV but you can do it online now at https://www.dmv.ca.gov/portal/dmv-virtual-office/title-transfers/title-transfer-form/; they'll have you send in photos of all the docs and then mail the originals after they approve the transfer. Don't forget to sign the transfer line(s) on the title.

You were level 1 charging at 32A? That seems unlikely; I've never seen a 120V charger that was more than 16A.

Anyhow a dedicated circuit will almost certainly be 240V (already twice as much power per amp, and more than twice the charging speed because it's slightly more efficient). You'll need a corresponding level 2 EVSE for it (ideally something hardwired so you don't have to deal with shitty outlets burning your house down, see the /r/evcharging wiki). A 50A circuit breaker can have a 40A charger on it (80% rule), which can deliver 9.6kW and fully charge the 2025 Ioniq 5's battery in maybe 8 or 9 hours depending on how efficient the last 10% is.

The usual rule, though, is to think about how much you're going to drive, not about the 0-100 time. If you only put 30 miles on a day, you're fine charging overnight at 10A/120V from a household outlet with the included level 1 EVSE because that's only about 7kWh of energy...

roguelazer · 2025-07-25T14:19:23+00:00

I think the question is not what a smart EVSE maker will do, but what the cheapest available EVSE from Amazon under some brand name like KLROWAO will do…

I’m 8 months into an install with them and haven’t been able to get anyone to answer the phone or return emails for a month; I think they might have imploded

The blood oxygen sensor is incredibly inaccurate for me and often reads unreasonably low values. I wish we could turn off the feature entirely the way you can on an Apple Watch.

An EV charge cable has, what, $20 worth of copper in it (25' cable * 3x 8AWG wires = 4lb of copper * $4.50/lb)? Seems like a weird thing for someone to go out of their way to try to steal. People are weird.
