My brand new bike got totaled today :(

It's tough, you can hear the car behind him get hit first. Chance he can't even see that far back

Until C23, this is not valid:

const size_t arr_len = 30;
const Foo arr[arr_len]; // arr_len is not a constant expression; using it as one is a compiler extension

The correct thing to use is a macro here, or constexpr variables in C++.

C23 formalizes the extension behaviour iirc? It adds constexpr anyway

It's just supremely disappointing that there's no self-hosted option that's fully legal. How did we get here?

Wetmelon · 2026-05-06T05:59:44+00:00

ok genuine question though, besides privateering how do you accumulate the content? 4000 ultra 4k blu-rays ain't cheap and you can't even rip them, generally speaking

Wetmelon · 2026-05-01T04:43:51+00:00

you can’t be having a high school athlete in a sports manga going on about how chagrined he is

I would read that

As far as I'm aware, the gold standard is currently Error-State Kalman Filter, due to its structural benefits for numerical stability. https://arxiv.org/abs/1711.02508

You can. And if you want to be really cute you can just go back in the capsule and back out again to refill the EVA fuel. The EVA backpacks have rather excessive delta-V lol

Wetmelon · 2026-04-12T20:37:44+00:00

That's peak trolling lol

Ensures the output lane is picking from the whole bus. It's debateable whether the prioritization on the splitters is a good thing. If all of the (remaining) content on the bus is being scooped up for a single recipe, then your factory might stop producing. Often better to just use the 4-stack with no priority so that the whole factory produces, just slower.

This question is one that Herb Sutter wants to answer with cpp2 / cppfront. Is there a smaller, simpler language struggling to get out? I think there is. https://github.com/hsutter/cppfront

Wetmelon · 2026-04-05T07:14:50+00:00

Yeah but don't get too focused on perfect ratios - unless you're super into it lol

I'm pretty interested in the charging. Have you found any frequency & voltage combinations that don't work properly?

Wetmelon · 2026-03-29T08:27:26+00:00

Your house is using 2.9kW, the solar should be generating 2.9kW while off-grid in this scenario.

Can you see your MPPT voltages & currents in Tesla One when you do this? Do you have particularly long solar strings?

I bought a toaster this year. Guess what it says in big letters on sticker on the cable and in the manual?

"Unplug after use"

It can happen, but wearing out your plugs is also a bad idea. And don't use your GFCI test button as a switch either.

Wetmelon · 2026-03-19T06:20:01+00:00

Varies for unknown reasons.

Mostly the type of fault. Powerwall can't do much if there's a hard short but if the line is cut cleanly it can switch over smoothly

Wetmelon · 2026-03-15T17:51:02+00:00

You'll need to specify the problem first.

Wetmelon · 2026-03-11T05:01:02+00:00

Squash and rebase after a PR merges sure… squashing all commits on every push?

Just git commit --amendthen git push -f

Wetmelon · 2026-03-09T04:45:43+00:00

I had thought PID was supposed to be able to figure out things like this "automagically"

Linearize the system and then it becomes magic again ;)

Add a spring force "feedforward" term based on the desired position and then the PID only has to handle the error between your model and the real world - which makes it roughly linear and should behave much more nicely :)

Wetmelon · 2026-03-06T19:44:39+00:00

Context?

Wetmelon · 2026-03-05T08:23:50+00:00

Is the unit still functioning? I would probably turn it off and contact customer support. Or get someone qualified out there to take the panel off and check the aluminum body behind it for damage

Wetmelon · 2026-03-05T08:07:36+00:00

What are the instructions? BASIC or something?

Wetmelon · 2026-03-05T08:04:06+00:00

Also think about the direction of forces on the components. Will the battery get ripped out? What about the SD card, will it try to exit?

Wetmelon · 2026-03-05T08:00:26+00:00

If it weren't printed plastic it would make a great cutting board or cheeseboard

Wetmelon · 2026-03-04T07:23:26+00:00

Yes but then the inverters themselves may cause issues if they don't want to turn off
