Right, having a second chip functioning as a watchdog which doesn't share the same silicon substrate mitigates the latchup. If you can recover before both theoretically could get struck, statistically you'll be okay. For added saf

I've taken a number of MCUs through radiation testing including testing watchdogs. I've generally found that latchups often take out the watchdogs, even something like the STm32 independent watchdogs, and shouldn't be relied

What's so odd about this is that they add the flash ($), but skip the magnetics! It just has series capacitors and I don't think the jack has integrated magnetics since it's small and it wouldn't make sense to have a ser

Yes, a boring mechanical key for both.

The latter. I had to use a physical key inserted into the door to unlock it. I agree, keyless start isn't a 'critical' feature.

I entirely agree that there is substantial tolerance for vehicle noise tolerance and this drives me crazy. Cities aren't loud, cars are! I just want to make clear though that replacing the ICE part with electric engines solves the prob

I had a similar experience in a rental. The one feature I missed was a wireless key fob, which is not included in the base trim. I understand the relentless cost pressure in automotive mfg, but that seems like it would have been $2 worth sp

Less than 5% of a full load. Any extra fuel you brought to the edge of space and back is lost performance, so substantial efforts are made to minimize this lost mass fraction.

Per Patrick Wardle, this was well reported to Apple during beta. https://x.com/patrickwardle/status/1836862900654461270

Source please? I'm aware of the large costs in the opposite direction due to the freeloading you mention: https://energyathaas.wordpress.com/2024/04/22/californias-ex...

Yes, forest is my exact use case, with roving devices that are too cheap to have phased arrays so get stuck on low gain antennas.

I have been very interested in 802.11ah halow (wifi in 900mhz ism band) to solve the inconvenient distances where 2.4g wifi has insufficient range, but something like a LTE catM modem is overkill. I'd be very disappointed if this effec

This gao report is about EUS, which isn't a fixed price contract, so really it is the taxpayer.

Alas there is no 'in general'. Acquisition is often the secret sauce due to, among other challenges, the extremely tight alignment requirement -- thermal shifts, satellite wobbling, etc, are all critical to manage. On wavelengths,

Take a look at the slides from the presentation, I think the geometry clearly shows cross-plane links in the mesh. Having worked on these types of systems, I've had more difficulty with the lookahead angles (rx from where the target wa

There has been a lot of work developing standards for reliable ethernet for industrial and automotive applications, resolving most of the issues you mention which apply to 100/1000Base-T. Tesla isn't using your garden variety ethe

Came to upvote this. The station works unreasonably well. The needles are pointy enough that they deform solder/copper a little bit and stay put once placed (you can flex the arm to preload the needle). You can buy it on the maker&#x27

Most panels shipped to space can't support themselves: Google "solar array deploy" and you'll see videos from lots of space missions where there are complex deployment jigs to hold the panels from collapsing under their

I chose Trident because I wanted a fair(er) comparison of costs due to purchasing power. If you want to use North Korean ICBM pricing, it's $30M[1]. THAAD is very expensive, that you're right about...but it's also the only in

THAAD interceptors look to be ~$100M each from a google search. I remember seeing a leaked document that suggested up to 3 interceptors would be fired at each target to guarantee a kill, but I can't find the document now, sorry. A Trid

It's nothing like the 100x graphics card though, it's the 1.2x graphics card, and perhaps a few percent more for efficiency improvements. If it's down as far as 80% after 25 years, replacing it will net you such a small impro

I dislike trash as much as the next person, but 50MT is 2% of global waste production (2000MT from my search). Is 50MT or (<1% of predicted 2050 waste) really that bad for generating most of the world's energy? This is before consid

It's less unreasonable than you think. The Ranger 1 spacecraft attempted to land a payload with an impactor before the US had figured out how to land more carefully.

But not in this case - It's only a 385 mile line. If it was between two synchronous grids, it would most certainly be AC for cost/tco reasons.

This probably isn't your issue, but I've had issues in the past, usually with a cell phone that sits in my pocket, that show up as cables no longer maintaining detent and falling out. The issue was actually accumulated dirt in the

Can you tell me more about this? Are you unable to hit line rates, or are you just commenting about lackluster io options? I'm looking to add some M.2 storage via thunderbolt enclosure to my machine and would otherwise be expecting to

Can confirm this from my own experience. Just elaborating on the availability requirements, the idea is that clouds aren't everywhere at the same time, so if you have enough in-space bandwidth, you can hop your traffic around the const

Interesting perspective. Another view: solar panels on your roof, using your car battery for your house nighttime needs means that during doomsday your energy intensive lifestyle doesn't have to change at all.

You have to be very careful when talking about relative pollutant emissions. Yes, the average EV is heavier and results in more tire wear and tire dust, but note that these particles are much larger (pm10 or larger) than most ICE particulat

Anecdotally from my experience in CA, my friends have been in a total of 6 crashes and not a single other driver was insured. Makes sense why my un/underinsured driver line item on my car insurance is ~40% of the total.
