The timeline lists "Sled tracks seen to broken bond ice, EMS called" at 16:44. He was pulled from the water at 18:57. The article text further clarifies:

Parents discovered sled tracks from home onto broken pond ice through which he fell.

He left the house at 16:00, which is why they give the range of 147 to 177 minutes.

Broadcom is publicly listed with a public float of about 98% (i.e. 98% of it's shares are listed publicly).

You're right that most shares are held by institutions (~80%), but that typically reflects the fact that most share ownership by individuals/companies goes through intermediaries (401k, fund investments, ETF etc.). Most of this institutional ownership is just asset managers, insurance, banks etc. taking their cut before passing returns/loses through to the end risk holder. The average institutional ownership of companies in the S&P500 for example is also ~80%.

None of this takes away from the point that Broadcom is absolutely run like a PE firm as the original commenter noted.

Not surprising given the CEO was appointed by KKR/Silverlake 20 years ago.

Just to add another data point, the co-CEO indicated on a podcast 18-months ago that the sensor package cost was <=$100k for the then current generation:

"But saying, you know, picking an upper bound, $100,000 worth of equipment on it, you amortize it over, you know, the lifetime, call it, say, 400,000 (miles), 25 cents per mile. Right. And, you know, it gives you some margin compared to the cost of paying a human driver."

He also mentioned that the next generation would see a "drastic reduction in the cost".

You're right, but it's not quite so black and white. They are certainly continuing to build out coal capacity, but they are building solar/hydro/nuclear/wind generation at a greater rate, such that the proportion of generation from coal has been falling, from over 70% ten years ago, to about 55% currently.

I think you meant capacitors. Resistors would just dissipate the energy as heat.

edit: Thanks for the correction. They do indeed use resistors and just dump the energy as heat. Unfortunate.

Hopefully this will change as supercaps continue to improve. Maxwell tech's modules are already used in light rail, and looks like some work towards smaller locomotives in Switzerland here:

Not sure about the US, but the Japanese didn't stop focusing on hybrid development. More than half of all sales in Japan are hybrids, whereas electric is only a few percent [1].

Honda even recently announced that they're scaling back on electric to focus on hybrids:

Chinese EVs are certainly strongly tariffed. The below Reuters article highlights how BYD are apparently shifting to plug-in hybrid sales to avoid the 27% tariff the EU imposes on its pure battery electric vehicles (plug-in hybrids attract a reduced 10% tariff).

Just a reminder to ensure that you have brownout detection enabled on the CPU/MCU (assuming it's available) and are checking for it in your firmware. Supply drops can be very brief.

It's on all the US embassy sites, although it says "are requested":

Effective immediately, all individuals applying for an F, M, or J nonimmigrant visa are requested to adjust the privacy settings on all of their social media accounts to ‘public’ to facilitate vetting necessary to establish their identity and admissibility to the United States under U.S. law.

True in many places, but in Hong Kong, the cost of an A&E visit or hospital admission for the author (presumably on a student visa) at that time was about USD15/day.

It is, but they fill them with silicone when they remove it. The brackets I was referring to are about 70cm wide, so no chance of leaving them there.

I find the single apartment scaffolding to be the most amazing. These guys turn up at the door of your 30th floor apartment with a bunch of bamboo poles and nylon strips and a couple of hours lated the entire side of the apartment is scafolded, like a spider's nest hanging off the side of the building.

To begin, one guy hangs out the window, drills a few holes in the outer concrete wall, and bolts a piece of L shaped steel to support the initial bamboo "floor". After that he's outside balancing on the first piece while he drills more and extends along the wall. Someone on the feeds the poles through the window.

He usually has a rope attached to a waist harness, which is initially held by someone inside, and then clipped to the braces outside... most of the time.

The whole thing is amazing to watch.

It's necessary every time you need to service something outside, like replacing or repairing aircon.

It's certainly possible. Tracing the MCUs IO lines to LEDs/buttons/relays etc on a PCB is usually pretty straightforward.

I have just finished doing this and writing replacement firmware for the Aqara E1 series of Zigbee switches, after getting fed up with them not supporting basic Zigbee binding functionality.

Aqara is a bit of a mixed bag. A lot of their switches are not Zigbee certified and don't conform to the standard. Specifically, they won't bind directly with devices from other manufacturers.

This might not matter if you're pushing everything through a hub like HA, but if you want to connect directly with other devices and remotes then it likely won't work.
