I understand and agree that we don't want knee-jerk reactions on the part of regulators. I'm only an aviation enthusiast and by no means an expert, and fully admit that I could be wrong, and even with my natural inclination to res

The Clipper Card system _must_ fall into this category. I recently called because I was certain my card was being fraudulently used--the value would dip $5-10 for a single ride, and there were top-up credit card transactions that didn'

I'm not an expert. But my understanding is that the "maximum propulsion" speed (587 mph) is limited by the "critical mach number" of the airframe, which for jetliners is something like 0.85. Faster than that, air ar

I love the A380 as an aerospace enthusiast, but absolutely despise it as a passenger. In my experience (with Lufthansa), the boarding process is chaotic and takes forever, the seat pitch is minimal in economy, and never have I felt more lik

I'm skeptical that birds have a means to dodge something moving at hundreds of miles per hour. If anything, a human controlling a drone from a distance has more perspective / ability to dodge a plane than a bird does. Now whether

Are there any cell providers out there that don't do this kind of shady stuff? It's unfortunate that this seems like another market failure, where consumers have no real choice and the only solution will be punishment/legisla

I'd love to read more about the crossbar and switching systems, can you recommend a specific book?

Pennies per play is a hard metric to grok. Let's compare this to CDs. Assume a CD costs $10, and half of that goes towards the distribution of the physical media. It has maybe ten tracks. If you listen to it every day for a few months

I don't see what about front-loading washers would make them especially prone to standing water or mold. I would expect that vertical washers could just as easily have standing water. Worse, it's probably out of sight behind the d

WeWork wouldn't be profitable on a private cabin model, as lovely as that sounds. Pitching the open floorplan as a "networking" perk is just a necessary evil, or good marketing, depending on how you look at it.

Sounds like an example of Goodhart's Law: "When a metric becomes a target, it ceases to be a good metric." Optimizing for something as abstruse as "engagement" seems like a great way to completely ignore everything

I'm surprised the article didn't recommend the simplest solution for individuals, which is to use ear plugs. Nowadays you can get versions that are tiny and flesh-colored, i.e. nearly invisible. I felt a little dorky wearing them

Not necessarily. Tests have costs and risks of their own. I would consider a test not justified in terms of cost and risk to be a "mistake". However doctors are far less likely to be sued for a thousand small mistakes than one big

I'm frankly surprised that more people haven't died at Schlitterbahn. Although this article appears to reference negligence at a corporate level, you have to keep in mind that the staff is comprised largely of high school aged kid

Honest question, is it truly possible to build yourself out of a housing crisis? Or is housing like roads, where an increased supply just leads to even more demand? In other words, traffic exists not because of a lack of roads per se, but b

If I'm pretty sure I had money in Mt Gox but I'm not sure how much, how could I ever file a "proof of claim"? It's not like Mt Gox was sending depositors balance statements every month or something.

Clothing, especially designer or specialty / technical clothing, can be marked up 1-10x. In other words, a jacket that costs $10 to produce might sell for $20 or $100. Don't worry, they are still making money on your wife. (This i

That seems utterly nonsensical and dehumanizing. If you have a human greeter/operator, why not expose that to the customer? You are already paying for the human to be in the loop, why not benefit from the impression of a friendly human

This sounds awfully similar to a well-known Prius problem, where the transition from regenerative to friction braking takes on the order of a second and can lead to significantly increased stopping distance.

It's not even necessarily a matter of inattention. Imagine that the autopilot was driving along just fine, and when it was just a few feet away from the parked cruiser suddenly veered towards it for whatever reason. It might be physica

Has anyone compared the rates of carbon monoxide poisoning with and without keyless ignition? I could actually see an argument for keyless being safer: if people can leave a car and completely forget to turn it off, they can certainly do th

Tesla's terrible response to this and the detrimental effect on its image must be pretty obvious to most of the HN crowd. I have to wonder why they persist. Is their PR spin actually having a positive effect on the public at large?

I wonder to what degree is shrinkage a compounding factor. I used to work at an outdoor retailer where we only did inventory once a year, and by the end of the year the computer inventory would differ from actual inventory by an order of ma

I wasn't in Hawaii, but I also imagine that I would assume that an alert like this is a false alarm. I've just lived through too many scenarios like this, albeit not on the same scale (think false fire alarms.) Upon reflection, ho

There are many insurance companies that use OBD GPS trackers, as well as standalone trackers that plug in to the cigarette lighter, in order to charge based on mileage. e.g. https://www.metromile.com/

Can anyone speculate what will happen if I'm using an unlocked Google device (Nexus 5X) on Verizon? Will the new app be force-installed somehow? And can it be removed?

It probably would have prevented the Tesla crash with the semi that cameras couldn't see due to low contrast with the sky. So I'd say pretty important. I'm actually shocked that Tesla has done so well without it.
