Complain to c3voc, specifically the video mixing! Without feedback like yours they won't know what's best.

Run 2 or 3 separate concurrent sync's and statistically compare the resulting clocks, for example.

Good thing cesium fountains are very accurate then...

There are many DCF77 receivers in Germany that are contained in a square box that's barely large enough for a AA battery; the rest of the square contains the motor/gears and the electronics/receiver (incl. a ferrite loopstick

Arguably monitors that are not mere TVs ought to allow control of each distinct pixel they drive internally and communicate their layout and if needed distinct brightness/color coordinates to the host. Exceptions can apply if the consu

They are good for infrequently used track and places where overhead wires would be in the way, like that very Tesla employee shuttle on it's own track and container ports. It's not the best way to go for mainline track and not sui

Are the words critical? As a German I read that as "you are not the priority road; you may only go left or right, but not straight"?

Huh, here in Germany we have street signs (mostly of a "you are the priority road" 45° rotated square yellow-on-white "sunny side up egg" sign and the "you are not the priority road" down-pointing white-on-red

You don't use ponds, you run the desalination to as strong as practical and follow up with either electrolysis or distillation of the brine. But once summer electricity becomes cheap enough due to solar production increasing to handle

Do you know how much magnesium you find with silicon and iron as olivine? It's just the silicon that we haven't yet tamed for large scale mechanical usage that makes them uneconomical to electrolyze.

We have 10 years of 2021 global energy production (including oil/coal/gas!) of LFP in the oceans; but yes, sodium batteries are probably cheaper.

Don't even really need notable heaters if you regulate your thermal vents enough.

2021 total world energy production of approximately 172 PWh would require 27.5 billion metric tons of lithium metal at typical 0.16g/Wh of a modern LFP cell; meanwhile, we have approximately 230 billion metric tons of lithium for takin

Grid scale LFP with once daily cycling lasts 30 years before the cells are degraded enough to think about recycling. And those are very low maintenance over that time. You're probably mostly going to swap voltage regulators and their f

If you're in the US just look up the small claims process local near you, and do it. The fee is small and you'll learn how it works, and that's worst case.

I'm the one who tried to make a low-mem builder for it that would work for merge sort like tasks that do some on-the-fly consolidation, e.g. LSM trees. > This project is neat, but it does basically just look like an rkyv-converted `

They are talking gigawatt. That pretty much implies dedicated long-distance transmission lines. The 1.4 GW they mention are very close to the full output of three mile island. This is not a small power situation that is done with existing p

Last I checked MIG was the only one that made hard promises about especially memory bandwidth; as long as your memory access patterns aren't secret and you have enough trust in the other guests not being highly unfriendly with their ca

Worry about the leg-thick power cable not the pinky-thin fiber. The cost of the fiber itself basically doesn't matter relative to a data center itself.

It doesn't just become invalid; almanac is good enough to use for satnav for over a day.

As a citizen I wish cars had similar driving break requirements as trucks do: mandatory 30 minutes break after 4.5 hours, 9-ish hours per day, minimum 9~11 ish hours break between driving days. Such minimum reasonable rest is what keeps you

Rkyv is basically the last thing you mentioned already? It's basically a code gen for deriving serialized structures that can be accessed for read with the exact same API and functionally almost identical (but not quite; in the differ

1) when did they downgrade? I've stared for hours at that particular code... 2) no you just don't get to move data freely. 3) I don't believe JSON has any place in a system that needs C because it can't handle Rust. 4) J

FETs are capacitors that can be internally shorted out. A good model for charge pump and duct switching converter understanding.

by namibj 11mo ago
Yeah PPS uses capacitive halvers. You can e.g. stack two half bridges, connect their switching nodes with a flying capacitor, and declare the connection of the stack the new switching node. If you use a series induction from the switching n

Yeah 120W is table stakes. Also Anker wall adapters are insulated that's worse for efficiency. Integer ratios can be done with GaN and class 1 ceramics and stray inductance to charge the GaN drain, so they only experience ZVS (they do

by namibj 11mo ago
ZVS (not ZCS) topologies that use planned stray inductance and WBG transistors and class 1 ceramics can operate at 10s of MHz with less than 1% of loss per voltage halving. They have insane power density and lack of wound inductors means th
