He put a fuse on every individual cell and on the overall unit, so I would say he was reasonably cautious (although he deployed a bunch of high-voltage exposed wires at the end of the video, but we can assume that was just a tech demo).
fuses only help for overcurrent scenarios. if they cell overdischarges due to a mechanical fault, or internally shorts, the fuses wont do anything. any then if it internally shorts at an SOC > like 20-30%, it'll vent and cascade into other cells.
The tire pollution is true, but the brakes hardly get used on an EV. They are almost for emergency use only. Mine has a special mode to disable regeneration for a while so you can use the brake pads to clean the rotors.
If you look at the ICE agents, they all seem to have a variety of random gear. People have found their patches on Amazon.
My impression is that they are on a hiring frenzy, and are incredibly disorganized.
An AXON body camera is $800, usually sold with a subscription. If these ICE agents are buying their own gear, I can see why they'd just buy a GoPro or use their phone.
I'm sure the lack of traceability and accountability from private recording is a welcome "feature" (at least by the individual officers). The fact that the organization hasn't apparently prioritized or required accountable body-worn cameras is suspicious and unacceptable, but the available evidence is that this is organizational stupidity and negligence.
Doesn’t the fact that they are filming at all point to the idea that they are at least aiming in the right direction (no pun intended), even if they still end up being disorganized and underfunded?
From my perspective they are most likely not heading in the right direction.
They are massively funded and will get more and more embolden to record their crimes and say do something about it.
Then it will be a wedge. Support ice or not. Armband or not. Salute or not. Which side are you on. Cowards will pick the more violent side for self preservation and will soon find a country that's not worth living in anymore.
For curiosity, when in history has the federal govt failed to suppress an uprising in the USA?
My suspicion as someone with lifelong weight struggles and having tried GLP-1 medication: overweight people require more willpower to lose or maintain weight relative to those of normal weight.
So the advise or admonishment of the normally weighted that losing weight "just requires willpower" is true but facile.
If we were to medically induce a constant feeling of hunger and insatiability into a person of normal weight, I'm sure they could keep the weight off, but would find that their willpower is highly depleted.
There are medications that cause increased appetite and weight gain (ex: some bipolar depression medications, prednisolone). This effect is so pronounced, that if a doctor sees the patient not gaining weight, they will suspect non-compliance and have to rule it out. Of course, some patients use extreme diet and exercise (willpower) to avoid these effects, but a normal person accustomed to expending a normal amount of willpower to maintain weight will find themselves gaining.
Having lots of lower powered routers is actually better for interference.
MacOS won't roam properly unless the signal from the connected AP drops below -75db, so cranking the power on all your APs will give you worse performance if you move around.
I feel like it's easier to just have Ethernet and a strict HW firewall with the admin interfaces totally disabled (have to full reset to get back in).
You can either just block packets in one direction, or you can add a small amount of risk and allow UDP and TCP with zero payload in one direction. That would allow you to reliably stream in one direction and request from either direction, albeit with a slightly exploitable channel (timing, reliability or the space of values allowed in the protocol).
You already have to trust the RPI hardware to not enable WiFi on either side, so why not trust a router?
> I feel like it's easier to just have Ethernet and a strict HW firewall with the admin interfaces totally disabled (have to full reset to get back in).
Easier? Maybe, for certain values of easy, but as others have noted it's not hard to build a data diode setup using fiber ethernet and from there you just have to hardcode some ARP data and maybe a route entry to allow UDP to flow.
The thing is that with your solution as long as the firewall works properly data shouldn't be able to leak in the wrong direction. With a proper data diode, as long as physics continues to function more or less how we understand it you can prove that data can not leak in the wrong direction. That's a huge difference, especially when it comes to explaining what you're doing to non-technical higher ups, auditors, lawyers, etc.
It won't change the economics of the current class of aircraft. They will still need to have business class seats to pay for the economy cabin.
You will probably end up with 5 or 6 tiers of service instead:
Supersonic: Business + First
Subsonic: Economy + Eco+ + Business + First
Supersonic First will be a Veblen good that has a high price floor (like $30k). Business for time sensitive business passengers, and it's actually an Economy Plus seat for ~$15k.
It's very hard to resist marketing some service differences, particularly when you have two classes of users with different needs (speed vs. prestige).
The pitch quoted from the post I was responding to essentially said it was going to siphon all the business class fliers from normal flights: "Give those passengers a supersonic plane, cut the flight time in half, and charge the same price." There's no way businesss travellers would choose subsonic travel if supersonice was the same price for half the time.
We agree I think that there wouldn't be a similar price between the sub and supersonic travel options. The economics of running the routes can't work out to a similar price to existing offerings.
They are a kinetic attack on the pins, but they don't shear or shatter them.
