If you look at georeference systems, they may fit a parametric equation with coefficients to a large set of earth data. The geoid in the link below is a refinement over an ellisoid (think lumpy potato vs smooth pebble), that gives you a 3D fit that has some level of accuracy with a very compact equation compared to carrying around the raw data. I'm thinking a supercomputer might be pretty useful to do the fit of data as it's updated, as well as giving options of using equations with different costs-to-fit on large data sets, or providing better fits on finer granularity.

Is a business accessing their lines via voip considered a landline?

I have a feeling that multiple carriers have a similar problem. I traveled to another city and noticed that some incoming spam calls shifted to incoming numbers with the local area code.

The Omega Tau podcast had some very interesting discussions about various improvements needed for fusions reactors to hit parity in their Wendelstein 7x episode. Some discussions I think come out all the more because the 7x was targeted to plasma research so many practical aspects are discussed outside the normal fusion discussion that hits regular science media.

It’s pretty well documented by political studies the delta between what voters broadly want and what political leadership in the US generally delivers. That poll covered Democratic, Republican and independent voters. Independents being the unorganized third party in similar size to both other main parties.

Is the access to provide data tagging inputs and outputs or to the model too? Will either the data or the model be open sourced?

A majority of voters of both parties support Medicare for All policy proposals.

Voters were split on the ACA mandated carriage of private insurance.

"According to the university’s lawyers at Nixon Peabody, the litigation is the first-of-its-kind 'direct patent enforcement' campaign against an entire industry."

Didn't the CSIRO from Australia do something similar with respect to their wifi patents?

I reject that low cost will create shortages in education, why? The more people we educate, the more are available to educate others. People, ingenuity, and education are a renewable resource.

The nice thing is that software and work on a RISC-V toolchain can now be much more common for vendors that elect to use RISC-V, though it remains to be seen how well the actual manufactured chip variation gets supported like instruction set extensions, peripherals, and configurations for many cores. ARM had some motivation to help ease the customization pain for tooling for their IP licensees, so I'm curious if RISC-V support will be more like ARM or more like early UNIX vendors.

I think that's why the raw cells aren't used as the level of swappable unit very often. If the battery is at all removable, they're often integrated into packs which have some level of built-in protection.

It's a shame that so many products default to built in, non-replaceable LiIons now. For many products, it's nicer to have a replaceable rechargeable so you can pop in charged battery and go instead of having to plan for state of charge of yet another device.

I think it would be interesting if they filtered out any entertainment & sports celebrities to see who remained.

A pizza place I went to had a system where your order was in a warming oven with individual doors. Punch in your order num, pull out your pizza box and go.

"A continuous measurement device connected to a computer/s will have a vast array of available diagnostics, 'most probably leading to less "dangerous undetected failures" than a simple switch, or combination of."

Isn't this exactly the approach that failed in the MCAS system? And if you had a switchable independent system, a copilot would have righted the plane and flown on.

But really I agree with your overall comment, it's very difficult to know why a given safety design decision was made unless you are well steeped in the system - there are almost always little corner tradeoffs. That's why I added the "I suspect" to the front of my comment.

As far as I understand it, it's something like generics for math theory.

I suspect combined reliability of a simple switch and two independent systems is likely higher than one composite system and pilots or software trying to estimate and select which combinations of computers & sensors are "good" in the middle of an emergency.

It matters, but if the rate of failure is high enough to be expected to be encountered within an all-fleet, constant flight environment for the lifetime of the aircraft, then you plan for failures as well as having the pilot know what to do when there is a failure.

In air sensors like this, their failures are higher than the rate at which you can ignore. They fail on their own, they get bumped and bent on the ground, they ice over in the air, or have objects striking them.

The pilot training is part of the overall systematic design, neither the equipment, nor the pilots exist alone.

All equipment on the plane has a potential for failure... the question is what systematic design and pilot training is in place to take action in the face of failures.

A wire transfer is a little different than an ACH. Some transactions seem to require wire transfer, not sure if that's just momentum or there is some other driving reason for the choice.

This other HN submission has some interesting hypotheticals on why the system might have been reactivated multiple times:

I suspect ADA would like those too, if available.

It's not uncommon for GPS repeaters to be installed in large buildings to pass the signal through to interior areas - I wonder if the repeater is picking up the LabSat device signal and propagating it.

You could buy your own, but I don't know how different the Edge TPU version is.

Except for Uber automated cars... but in general I agree with you. The safety critical development areas are generally wrapped in safety critical processes with extensive process checks, and I would suspect Uber now has better practices.

Similarly not-COTS, but a series of UAVs, a Zephyr "7" made a record 336 hour flight - 14 days, with an unofficial runs of three minutes (!!) short of 26 days aloft for a recent Zephyr S.

The CubeSat projects at Cal Poly and Stanford I think are what led to lowering costs and allowing the launch of riskier hardware and spawned this corner of the space industry. Planet was definitely one of the first to have the vision to commercialize that capability.

Although the article talks of LED wearout, I think the key data was a survey of outdoor LED systems: 10% of failures are the LED itself, the other 90% is support components that fail causing shorter lifetimes.

I'm curious how it compares to the LED filament lighting which can use much simpler power supplies with fewer components which should mean much lower failure rates.
