chipsa··on 'Starwashing': The new space race has an environmental problem
Space companies shouldn't try to help us out of this crab bucket. They should work to try to make this bucket full of crabs better. We should pull down any crabs that try to get out of this bucket.
chipsa··on Feature Request: Support AGENTS.md
> My theory is that as startups grow beyond a critical threshold, they start to attract a certain type of person who is more interested in mercenarily growing within the company / setting themselves up for future corporate rise than building a product.

chipsa··on Alternate clock designs and time systems
False. The existing months were just renamed after them. Rather, they added new months to the front of the year (January and February).
chipsa··on Electric motors with no rare earths
If the desired location for this is a car, then a few years of life that requires half disassembly of a motor isn’t going to work.
chipsa··on Kona EV Hacking
Range extender was definitely a requirement when I got mine in ‘19. But that’s because I did not have reliable charging available in the area.

It also came in handy for a bad road trip (charging stations more than my range apart, so I couldn’t otherwise get there from here, but hold state of charge kept it up at 75% with frequent gas stops)

chipsa··on Following 35% growth, solar has passed hydro on US grid
I got panels last year because I’m pretty confident that the majority of the cost of putting panels on my roof is the stuff besides the actual panels. So pricing won’t go down much for getting an actual installer to do it.
chipsa··on Following 35% growth, solar has passed hydro on US grid
Very much depends on the rating. A residential panel is something like 65”x40”. A commercial sized panel is something like 80”x40”. The cell size is relatively constant, but the bigger panels are 6x12 cells instead of 6x10. Newer panels have more efficient cells, and so higher power.

Panel manufacturers can also do odder sizes as required. Example: q-cell does a 94x51” panel. This is 6x22 cells, but different sized cells as well.

Most panels are 6x, because that results in an open circuit voltage of just shy of 50V, which is convenient for code compliance.

chipsa··on Banned in California
It’s not claiming: you can’t have an automotive paint shop. It’s claiming you can’t start a new paint shop. Specifically, if you don’t have one for your car manufacturing line already, you can’t set one up. Wikipedia shows 13 pages for auto plants in CA. Most of them have the verb “was” in the opening sentence. There are two current plants: Tesla Fremont and Toyota California. Both of these plants are over 50 years old, and only one of them produces actual cars instead of parts.
chipsa··on Flipper Zero dark web firmware bypasses rolling code security
I promise there is not an OBD2 port inside the headlights of cars.

There is CANBUS to the headlights, but that is not a OBD2 port. And more securely designed cars can put that in a less secure zone, so it can only send and receive commands for exterior things like lights, and not be able to have commands for keys injected, because that bus will not accept those commands.

chipsa··on Telo MT1
More advanced EVSEs are capable of adjusting the power delivered based on the power available. It does require a sensor on the supply cables to determine how much power is being used, but it's technically capable without a service upgrade. Also, electric companies will frequently upgrade an old 50/100 amp service to 200 amp for low or no cost (because they figure you'll pay off the cost of doing so through more power usage). The panel side of the service upgrade will cost you, but then you'll be able use the toaster oven at the same time as the A/C.
chipsa··on Caches: LRU vs. Random
Quick sort usually uses something like insertion sort when the number of items is low, because the constants are better at low n, even if O(n) isn’t as good.

The third row is just planned. They do not have any publicly available views of it, and the currently non-removable back glass of the prototypes inhibit actually installing and using them.

The vast majority of tractor trailers in Europe are cab over designs. There’s definitely less room between the bumper and the driver’s legs in those than in any standard pickup truck.
chipsa··on Telo MT1
I don’t think slate has a four door option. It’s still two door, but with a rear seat that you can clamber into after pushing the front seat forward.

Do you have power at the lake house? Then you have charging infrastructure. Also, why are you towing the boat to and from the lake house?

And again, which new production pickup fits 6 people?

chipsa··on Telo MT1
You think a crumple zone isn’t required by current FMVSS, which they are designing against? That is, in fact, what they referred to with “ structural technology”.
chipsa··on Telo MT1
No pickup will do that. Even crew cab pickups normally max out at 5 people (4 passengers), because there is no bench seat up front anymore. Even a Ford Maverick is $30k or so, and that won’t tow a 5000lb boat. Max listed towing is 4klb.

Important note: if you’ve failed a medical, you’re no longer eligible for a light sport license. This is what’s killed Xyla Foxlin’s flying career: her medical was revoked.
chipsa··on The natural diamond industry is getting rocked. Thank the lab-grown variety
That includes stuff like diamond grit. You don’t care about the color or clarity of grit. Tenth of a carat on up? You care about that for jewelry use. And that translates into better non-grit industrial diamonds as well.

What you need for running a site that people might not like: 1. Your own servers 2. Your own network 3. Your own CDN 4. Your own payment processor

Step 4 gets you thrown in jail for violating AML.

chipsa··on Europe's first geostationary sounder satellite is launched
Google says: no, the US did not stop sharing weather data. Communication isn’t automated weather data sharing. The data never stopped. Again, citation needed.
chipsa··on Europe's first geostationary sounder satellite is launched
> for example, the US has stopped sharing weather data with canada.

Citation needed. Most weather data from NWS is required by treaty to be disseminated through WMO compliant methods. The Metsat data is transmitted unencrypted from the GOES sats. I don’t believe they even have the capability to encrypt it. It’s only DoD weather data that’s not being widely disseminated, AFAIK.

10 gallons of water is like 80 pounds of snow. Even with the relative density, 80 pounds of snow isn’t going to do much for avalanche.
chipsa··on Price of rice in Japan falls below ¥4k per 5kg
There’s also the shipping problem: it’s actually cheaper to ship from overseas than the US, due to the Jones Act. There’s more ships available to go from East Asia than from California.
chipsa··on Cell Towers Can Double as Cheap Radar Systems for Ports and Harbors (2014)
Doubt: the APQ-181 radar on the B-2 is a Ku band radar, about 15 GHz. Tamara is about 1 GHz. This is entirely incompatible frequency ranges.

Also, the APQ-181 is a LPI radar, which means it’s specifically designed to avoid correlation of signals such that you can track by the signals emitted. There are presumably some downsides to working in LPI, but the upside is that the signal is designed to be indistinguishable from an increased noise floor.

Most of the aggressiveness of a toy rocket is the smaller length. Orbital class rockets are literally the size of skyscrapers.

Can you identify the rocket he used? Because from what I saw, I’m pretty sure it was a F9.

You think they’ll still be in for 20 years? And you need 20 “good years” to get a pension for non-active duty service.

The point of commissioning them isn’t for them to take command of a line infantry battalion. It’s to have them have authority to do stuff that requires a Lt col, but is not actually commanding. It’s like how we commissioned a whole bunch of people in WWII to do admin jobs.
