Many airlines (ex. United Airlines) allow refunds within 24 hours of purchase, regardless of general rules of the ticket.

Absolutely true!

It’s a great guide - but there are two main limitations.

First, this is the DFM guide specifically for Seeed. Every factory will have a different set of specs depending on equipment (assembly, test, and inspection, and familiarity of operating personnel), throughout requirements, yield requirements and price points, rework allowance, and so on.

Second, these typically assume for wide tolerances. Operating environment or design may necessitate relaxing some parameters in order to allow others to tighten (aka the tolerance stack up).

Dealing with both cases effectively in volume production is what requires experience beyond the manufacturer provided DFM guide.

Someone who learns this guide inside and out will be able to DFM with Seeed but not necessarily anyone else.

More generally, the DFM guidelines for ceramic RF materials would be wildly different than for Kapton flex connectors or for standard FR4 material.

Sure, if the inbound bus wasn’t late, or there wasn’t traffic, or...

Right - and that's what would drive US based companies just to shut down access to EU versus trying to comply. The uncertainty may not be worth it for small companies just trying to gauge demand.

If there is only one possible outcome, then that outcome should be clearly encoded in the law. The whole purpose of the court system is to provide interpretation when a law is vague - intentionally or not.

Humidity - carbon fiber fuselage can support more water in the cabin atmosphere.

Toyota has an existing partnership with Uber for leases to drivers.

If Uber's thesis - that app-hailing will supplant car ownership - is correct, then car manufacturers have an incentive to either create their own hailing networks or partner with existing ones.

A huge fraction of cars driven by Uber drivers are made by Toyota. More often than not, you'll get picked up by a Prius, Corolla, or Camry. So to some extent, this is about maintaining market share.

Absolutely agreed

What is repeatability? 10% of the time? 50% of the time? 99% of the time? 99.9999% of the time?

Even medications made in high volume processes have rejected units (and sometimes, batches). Process drifted, machine failed, raw ingredients had some issue.

A scientific paper at the very early stage is meant to show that something is possible if the conditions are just right. It may be actually outside the capability of the lab to document (or measure, or even know) every variable that makes up these conditions. One of the reasons there is such a chasm between lab and practice is that as people dive in for deeper review and productization, they find the process is too finicky, the applicability too narrow, etc. But the scientific paper is the first step in this process of discovery.

That said, it's critical that authors document whatever they do know or have control over. Electronic publishing, tools like Github, etc, all make the barrier for disclosure much lower.

Would be super helpful for corporate offices. Input a list of employee home addresses and find commute time isoclines, or locations which minimize mean or median commute.

Knowledge leaks onto employees even in factories. That's why a welder with 30 years of experience is different than one that is fresh out of trade school. Better knowledge of tools, techniques, etc. You could hire a senior welder and set up your own operation from scratch.

The military signal is encrypted and on a different band. Only the military has access to that signal.

Yeah...at a startup, doing this many 1:1s doesn't make too much sense. Doing a bunch of 1:1 to get people going the same direction means they weren't already in the same direction...means you're burning resources. At BigCo it makes perfect sense since there's 1000 things going on and no one cares about your thing until you show them why.

(hi!)

Tokyo metro is one company of many that provide subway services in Tokyo. There’s also JR, Keisei, and several other companies. Some are fully private, some are joint ventures with the government - but key is that none of these companies have oversight power over themselves.

Suggest that you actually look at privately run transit infrastructure that exists today. Tokyo subway systems (JR, Tokyo Metro, Keisei) - all private. Or Hong Kong - MTR is private.

The real problem is putting operations and verification in the same hat - public or private. Private transit systems work well when government regulators have the power to set and enforce a strict SLA. They fail without oversight. Same with public systems. When the operational and regulatory agency are the same, it becomes hard to penalize failures.

And yet in a congested city, the closest car parking may be 2-3 blocks. Not a huge advantage over bike docks.

I bet there are some steps within the tent that have better yields or better QC than inside the factory (others are undoubdtedly worse). How do those effectively get transferred over? Thats technical debt.

For most people, it takes conscious thought and effort to take an impression and articulate it. When you tell your references ahead of time, you're giving them a chance to take their impression/opinion/emotion of you and figure out how to put it into words ahead of time. There's nothing artificial about the outcome if you give them the time to do this. In fact it may seem more natural since they aren't nervous and on the spot!

Value based pricing. More willingness to pay for ex-US fares than from anywhere else in the world.

Many stores will have custom SKU or model IDs, so a mattress that is physically identical and cheaper somewhere else is actually a different product per the paperwork...

Depends. But most airports define the MCT based on their primary usage So - are they primarily a transit hub? Endpoint? Etc.

Base model Leaf or Electric Smart? You’ll still get cruise control (you don’t need to use it), ABS (proven to save lives, but you can of course pump the brakes if you wish) etc.

There’s a defined “minimum connection time” for each airport which you need to manually check when booking separate tickets.

> Checking if I have connecting flights can be done without knowing my name

Not always. Many airlines (for example, American Airlines) will protect your connection even if you've purchased two separate tickets. And they'll do this across their entire OneWorld alliance of airlines, not just within the company. But unless you have added a frequent flier number, the airline needs multiple matching information (Name, DOB) to be able to make the link between your two reservations automatically. Otherwise, they would be unable to proactively rebook, hold the connecting plane, have someone meet you at the gate to rush you to the next gate, etc.

Specifically with history, contemporary topics being skipped over is not only common but an incredible disservice to humanity. Many schools spend months on Columbus but only 1-2 weeks on the entire post Cold War era. Which one is more important for future voters to understand?

Emirates (subject of this thread) almost exclusively flies super long haul overnights. Their proposal wouldn’t work for the domestic 2-3 hr hops, but does work well for that 12 hour flight where one person trying to look outside wakes the whole cabin.

It’s not always just about the money. One of the most effective ways to ensure that a long-term project stays alive at a big company as people come and go is to create an external tie-up or partnership.

Most geniuses aren't assholes. But no one writes news stories about individuals that have no drama and are pleasant to work with.
