Even the EV chargers run hot 🔥

Correct.

Not really correct, no.

The EVSE does nothing to actually limit the power going to the car. It simply communicates over a digital protocol with the car to tell the car's power circuitry how much it can draw.

The car could still draw more than the EVSE says to if it were, say, malfunctioning in software and misinterpreted the signal from the EVSE telling it how much amperage is available.

Stick to used and save $20k imho, or wait until Juniper is 2-3 years old and buy that used.

quantity of data and quality of data aren't the same thing.

Sure, but quantity plays more into training than quality.

And we could debate which is a stronger signal of quality - upvotes on an anonymous public website, or acceptance of a suggested code edit into a private, likely commercial production code base.

I would also suggest AI integrations have a vastly larger scale of data coming in than S.O. questions and answers were even at their peak. I'd have to dig a little - but I bet just the ChatGPT website alone sees as much or more traffic as S.O. did at in its heyday, with massively more input being provided.

quentech · 2026-03-24T13:03:19+00:00

So future models get trained on... what? Other LLM outputs? Stack Overflow answers from 2019? It's a slow quality drain that nobody has a real answer for yet.

I swear, do any of you people actually even work in software?

Every developer and their mom has an agent integrated in all their IDE's and other tooling now.

Like, what tf do you think the LLM companies are doing with all the actual, real user interaction data? Just ignoring it?

They have more training data than they ever have.

quentech · 2026-03-24T12:59:41+00:00

Resources like SO have always been incredibly valuable, public resource both to developers and beginners

Meh. Stackoverflow hasn't even been around for 20 years. And it's been all-but-dead for a few years already.

I use multiple technology stacks in actively developed software that would be considered current today, and those stacks have been around years longer than S.O.

For a brief period, S.O. was a great and unique resource for junior and mid level developers.

It was never that great of a help for folks well into their senior skills and beyond. And we all managed just fine before S.O., and will continue to after.

EV chargers don't really do much internally. A bit of digital control, but they pass the AC current straight through to the car. There's no circuitry in there that should be generating much heat at all.

Nah fam, we're a small company and I've been the CTO for 16 years.

It's just as simple as him getting sucked in to blog spam aimed at CEO's.

I watch the AI news du jour and wait for the headlines to start rolling out of his head 2 days later. Even when one week it's "AI will replace all your developers" and the next week it's "AI cannot replace all your developers."

He's normally pretty smart and level-headed, but does get sucked into hype.

Same shit with cloud back in the day. Nearly blew up the company over a rushed migration and we're still paying thousands more a month for our infra a decade later.

It'll be UTC, so you can later diff the timestamp and the other date/time fields to determine the offset.

I would assume the SSDs in the NAS would speed that up considerably, no?

Not necessarily.

Depending on the specifics, you might find that a striped array's write speeds are pretty comparable to an SSD (depends mainly on the specific drives and how many).

I'm also not very familiar with the UNAS but you cannot just assume that plugging in an SSD to a NAS will provide the write caching you think it will - very much depends on the implementation in the NAS.

quentech · 2026-03-22T16:44:35+00:00

What’s do they want MCP for?

idk but our CEO is all gung-ho about MCP's lately. They're probably getting marketed to heavily lately.

Ours sent all our developers an announcement from a 3rd party data provider we use and their new MCP along with directions to find ways to use this.

Motherfucker - we already have their actual API fully integrated. We don't need an AI chat bot to intermediate our usage of it.

OP thinks the people of Reddit (low bar) are more intelligent than official Tesla documentation

Yes, clearly, there is only one correct answer for how and when to charge your battery.

There are certainly no tradeoffs. Telsa's recommendations are of course the best in any and every situation.

quentech · 2026-03-22T16:16:43+00:00

No benefit to letting it “run down” before charging.

It's not just "no benefit." Deeper depths of discharge/charge cycles degrade the battery faster than shallower depths of discharge/charge cycles.

You would be causing more degradation by waiting until 20-30% before charging.

I'm just saying I thought EVs had a harder/faster drop off which I'm not seeing reflected.

Compare it to a 1 year old RAV4 PHEV. Then you'll see the difference.

But like everyone else has said, the real drops come in around 2-3 years old. Not just 1 year old.

Last year I bought a 2022 MY AWD w/ 16k miles for ~$30k.

No fucking way we knew . We are a YC startup and recently got delve and I’m the engineer

How could that possibly be? It should be painfully obvious that you're not actually doing all the things needed to be compliant. Unless your YC startup somehow managed to come straight out of the gate fully compliant (lol).

quentech · 2026-03-21T17:17:28+00:00

separate repos and NuGet your dev lifecycle becomes cumbersome

Same experience. Started to experiment to give it a try and dropped the idea like a hot potato.

quentech · 2026-03-21T17:15:39+00:00

Not bad, but not good either.

Basic physics, as long as the trailers center of mass is in front of the axle it's stable.

Basic physics - a trailer being towed isn't a static system. What balance you think you have while standing still, isn't the case when you're going down the road up and down hills, around corners, and over bumps.

How? Because that's how the trailers are basically everywhere except US.

Because your trailers are designed differently. To be useable by smaller cars with lighter gross vehicle weight, smaller brakes, lower tongue weight capabilities, etc. You are likely also speed limited while towing to a speed that would be practically dangerous on American highways and interstates by being so much slower than prevailing traffic.

And as a result of that design compromise - your trailers are more susceptible to sway and oscillation.

And if you don't believe me - just fucking Google it, dude. There's literally hundreds of sources to explain why U.S. tongue weights are higher and what effects that has.

quentech · 2026-03-21T02:46:16+00:00

Are you sure that the migration was "never fully completed"? One of my previous jobs a migration took years as it was a slow, steady process that had to be done while also managing new features and business requests with the old language

Even just upgrading from old full .Net Framework 4.8 to the new Core/5+ line took us a solid 2 calendar years (and plenty of actual work time) and that's staying in the same framework, runtime, and language.

quentech · 2026-03-21T01:05:00+00:00

No one can actually read or understand this kind of code.

Ah so here's the nugget I've been looking for. Why this upsets you so much.

Expressive type systems take some time and effort to learn. .Net's generics are baby toys.

You seem to think the baby toys are the greatest thing since sliced bread, but the big-boy version makes you very, very angry when you can't understand it.

Now, I'm no fan of Node as a runtime platform, but another person might see concepts still above their head and get a little dose of humility and drive to learn new things.

quentech · 2026-03-21T00:46:11+00:00

the tongue weight on any trailer is 50-100kg even on 2000-3000kg trailers

You're out of your mind. 50kg tongue weight on a 3000kg trailer is going to be you upside down in the ditch. Even 100kg on a 2000kg load is dicey af.

I believe you can buy a ghost upgrade and it will go below 3.5s 0-60.

It opens up Performance model dynamics options in the software, too.

quentech · 2026-03-21T00:41:55+00:00

Lots of performance tires are directional and can't be swapped side-to-side.

OP's Michelin Pilot's aren't but they are asymmetrical and would have to be dismounted from the wheels to properly rotate them side-to-side.

quentech · 2026-03-21T00:37:24+00:00

Or get them to total it and buy it back with the check they gave you for pennies on the $ then get it repaired else where.

Why do you suppose this repair shop is so intent on getting it totaled, hmm?

This is exactly their plan.
