On that note, I was really impressed with how easy it was to end an xmradio trial subscription just recently. I had gone over a few days into their regular monthly service. I was anticipating something unpleasant, but it was very easy to cancel, and they refunded the new month pro-rata without prompting.

HDF is multidimensional and carries metadata.

That would be a terrible device design regardless of if the approved software is being used on it or not. I suspect it's not nearly that risky.

Badger looks nicely done! Did you end up needing to change much in implementing Badger from what was described in the WiscKey paper?

Chris Gammel is co-host of an electronics podcast called The Amp Hour. The podcast isn't instructional, more for context and discussion, but Chris also offers an online course that takes you through the entire process of PCB design. I'd peruse the podcast episodes, checkout the forum, and consider the course.

And is it production estimate, or a production goal? If someone gives you a goal of 1000x the current production, assuming you can request/specify whatever you need to get there, that's very different than if they say, given the exact production line we have now, what is the estimate of what we can produce. Tesla was somewhere in between given they were at the stage of thinking about setting up the production lines and going to setup them up simultaneously.

For diagnosing, I like building up a cumulative distribution function (CDF) plot. If you're collecting data either for percentiles or thresholds you likely have the data already. If you're setting thresholds, it's a useful plot to judge how likely a given threshold might trigger an alarm.

Short answer, it's within the purview assigned to the NTSB.

Longer answer: pipelines are a form of bulk material transport and are a non-trivial bit of transportation infrastructure. The NTSB seems like not too bad a place to assign accident investigation for pipeline accidents.

So there's a lot of coverage about the EU parliament process, but where did the drive for this copyright directive come from? There seems to very little coverage on how this directive came about. Whose interests are being represented by these changes?

I'd speculate that the simplest root cause might be an system overpressure. Any hookup to a valve that couldn't contain a pressure of some level could be susceptible to leaking gas onto an ignition source which could then start a fire.

Now try to buy one from the apple site...

"the majority [of heat comes] from the train hitting the brakes as it pulls into the station, an intense friction that gives off an exorbitant amount of warm air."

I wonder if regenerative brakes can be installed (or are already installed...)

I'm sort of a Mulally fan, he I think was fairly critical in how smoothly the 777 development was for Boeing - and was passed up to be CEO of Boeing, and went to Ford as CEO instead. But I wonder that today Ford is in something a problem spot, and how much of that (if any) is attributable to Mulally.

Some expertise can be bought, but some of the support is built over time, intrinsically outside the factory into the overall Toyota system. But ironically, thinking one can just buy an expert is to apply the same short-term mentality to the process that Tesla is accused of misapplying to product.

When Toyota first started creating their own US factories, they took the steps of shipping floor employees in the US to japan a few at a time and working for weeks of training each class. When other auto companies tried to replicate Toyota processes in their own factories, it didn't help yield in the factories in many cases because often the input supplies needed so much rework. And then they had problems changing suppliers configurations because those relationships were contentious, and not of the nature of Toyota to it's suppliers. When you're trying to stand the whole system up at once, it's not just a matter of "don't write bugs" in one part of the final assembly.

When Boeing reworked it's production design process for the 787, they had years of production problems to re-iron out, despite having years of great process experience previously.

Telsa really should aspire to Toyota levels of efficiency, but you also have to account for the fact that Toyota has had decades of experience as well as a stable and long-term relationship with their parts suppliers. Stopping the line and reconfiguring that plant in a Toyota plant is likely a minor rework for efficiency. But when a model and line and entire system is all new, a stoppage might not be a small rework despite best efforts to have arranged for it to be so ahead of time. Even the timeline and difficulty to setup a new Toyota plant vs a new Tesla plant aren't really comparable, because Toyota also has and excellent and stable set of design practices and supplier relationships. If two to three years from now, the rework ratio hasn't dropped considerably then Tesla is doing something wrong, but right now I think it's understandable that Tesla is just getting on it's legs wrt truly mass production. You always have to learn new things at each order of magnitude of production - even with products and methods that have been successful at the previous production level.

That was my first thought too. But there is this quote:

> The software can detect hidden objects using technology that examines the naturally occurring waves produced by a person’s body. The technology does not emit radiation, officials added.

A company will also pay for and pass on the cost of non-paying customers in terms of repossession or loss of rented units.

I suspect for long term goods that are below some cost, it's just cheaper for people to own them vs renting over the lifetime of the device. A corporation will tend to finance the capital cost of the good if it's renting, then needs to pass on the interest costs of those goods to the renters. On top of that a rental corp also need to maintain techs to install/remove appliances. It all adds up to higher cost to rent than own in this area.

You can rent fridges right now, few people elect to do it...

It sounds like a nightmare to me.

A fridge service provider might run the hardware longer, but they wouldn't care much about your power bill, nor fridge features - if old phone monopolies, cable boxes and current isp's are any indicator.

And good luck trying to prove to a fridge service provider that their unit has an intermittent thermostat problem...

Recycling might be the responsibility of the company, but they might systematically find the cheapest way to do it without regard to the full externalities of how it's accomplished.

The landfills often tap the fill for methane generated by the contents. I happened to run into a guy the other day who worked at the power generation plant for one of these. The theory is that burning the methane to produce electric, and breaking it down to CO2 is generally preferable than the slow leak of it into the atmosphere where methane has a stronger greenhouse gas effect than CO2.

Edit: stronger not "strong"

It's very subjective, but I've been comparing the "create a station" from a spotify playlist to Pandora for a while, and just find more music that I both like and have never heard of from Pandora than spotify. Then I generally add the tracks I like best to a spotify playlist.

On the other hand, Pandora, it feels like has recently been making picks that somewhat mush your likes and seeds from all your stations together.

I still feel like Pandora does the best job of finding similar new music to an initial set of tracks, but other than that I like most aspects of spotify better.

For one, prerendered 3D video could go as detailed as the transfer pipe & display would allow.

For another, the worst case cost is $x/45, but I would think that might improve as 3D programmers figure out optimizations in terms of multi angle view rendering.

If you think it's mostly unfamiliarity, then that's a great opportunity to suggest some time spent to document that code (and/or operations thru that code). It helps w/ the understanding, and should be a precursor to figuring out if a redesign could help that "tech debt".

Start identifying specific markets/customers and think about how one might move towards packaging/productizing your prototype for those customers.

It's not completely clear to me if your prototype is currently FPGA code, or maybe sensor hardware. For silicon IP a few questions might be:

Are there any customers who might reasonably deploy with your tech on FPGA?

Can you port your prototype to a GPU implementation? Would that open markets/customers to you?

Do you expect customers to port to a silicon implementation of your IP?

Other question might be, how clear of IP is your prototype. Do you own the full copyrights to the FPA code you intend to sell? Does it infringe on any patents?

Is it worth licensing into silicon IP "catalog" type companies? (This might include the FPGA vendors themselves too...)

Yes, as a customer, I think Amazon has been accumulating negative aspects of Ebay marketplaces faster than Ebay has been acquiring positive aspects of Amazon. That said, I have recently found myself buying some products on Ebay (w/o going thru the auction rigamarole) because they're priced better than Amazon .

I liked the Dragon Box Algebra apps for my kids at the time , and I see now they have one configured for age 5+, but I am not sure how well it sticks at that age.

"Unpaid", but members of congress are allowed to inside trade, and their portfolios are curiously successful.

Thanks for the reply! May I ask how far you go with respect to reliability/availability? Do you have a live replicated server on stand by or just replicate a log stream elsewhere, something else?
