Jane Street has a tech podcast that's worth listening: https://open.spotify.com/show/3ig6FgIbASpqJbc9chD2CI?si=etXY... The episodes on compiler optimization, time keeping and multicast are specifically interesting

Not entirely "nothing", as a result of HFT market making all participants are getting smaller spreads and increased liquidity. However... That has huge diminishing returns. The first few steps to electronic markets and fast market

Jup, except that a helicopter system does not use independent control. The blade angle is controlled mechanically, each next blade will at the same position have the same angle. This new thing seems like it has independent control of each b

What brand and model year is that? The first (15 years ago) system from BMW did that too, but the newer ones (2019 model, don't know about the years in between) know which lane the other car is in. There is a setting on European models

BMW still has it. Mine will display a large warning triangle with a pedestrian in it projected on the windscreen, and then you can look at the nav display to view the night camera view from the grill with the person highlighted in yellow (t

The passengers don't know about the flight plan. The screen at the gate and tickets just say Tel Aviv to Amsterdam. But the formal flightplan says Tel Aviv to Antwerp with Amsterdam as the destination alternate. You go to Amsterdam 99%

It's very small so the per seat usage is higher than a high density airliner. The comparison to a Cessna Caravan makes some sense, that's similar sized turbine powered.

It's more efficient than a low flying aircraft, due to reduced drag from ground effect. But it's not more efficient than a high flying airplane getting reduced drag from lower air density. So it works on short distances where the

Yes and some airport/approaches have a high enough risk that there is a warning. Düsseldorf for example has a box with something like "Don't confuse Essen airport X miles north-east when approaching runway 23" drawn on t

This is also for weight and balance / performance calculations. If the calculations are done for 150 passengers and you count only 149 (or 151), you can't legally take off without new paperwork.

Only for flights that leave the Schengen zone. No ID required for Amsterdam to Paris or something like that. The reason they ask on a fight to the US or Asia or something is that the airline is responsible to bring the passenger back to the

That's a dispatch screw-up before departure, not a pilot. That plane will have been on a valid flight plan but to the wrong place, there is no way for the flight crew to go to a completely different place than the flight plan. Because

This isn't as sketchy as it sounds. There is an official procedure for "in flight replanning" that's pre-approved by local aviation authorities. It can be used to stretch the range of a fight in case of good weather whil

You're quite accurately describing traffic enforcement in Switzerland and recently larger Belgian cities.

We also sat in the luggage area of a station wagon with 5 kids on the way to the swimming pool... That would probably get the driver arrested if you did it today.

Probably the liability is also different? You're much more likely to be liable for some things in the US compared to other places. In my part of Europe, if someone breaks something while making normal use of your trampoline that would

There is an important additional factor, regulators are setting limits on rates / rate increases. Florida is not profitable with those limits. If the insurance companies are free to set any rate, they would happily cover a high hurrica

I think the most common reason is that insurance companies try to attract new customers with lower rates / discounts and welcome gifts. Switching every year means a new insurance company spends their acquisition money on you every year

It's not about a "timezone", the article is about high precision time keeping and how to set a standard for it on the moon. Because (according to the article) an earth clock when moved to the moon wold be a few micro seconds

Some industries do this using UTC. For example flight departure and arrival times are in UTC on all paperwork. And also the meteo reports and forecasts, and airspace restrictions, and airport opening times etc. Mostly out of a necessity tha

Interesting, it works the other way around here. You get a portable barcode gun that you carry around the store or put in a sort of cup holder on the cart. So I always bring a bag or a foldable crate, throw everything in while shopping and

Yes it's great. Put everything straight in your bag, no packing at the end. The only thing I don't like is that they have added the option to the machines to scan all your things there instead of using the portable scanner. Which

Intelligence agencies are very careful about sharing their findings, even with "friends", because the findings will disclose some information about their capabilities and possibly methods. Let's say agency A has some scanning

Not really. Planes can't fly without pilots. Even flying a large jet with a single pilot instead of two would be very hard. It can be landed in an emergency (e.g. one pilot incapacitated), but it is hard work for the remaining pilot an

Maybe their organisation has a policy that requires stronger encryption? Possibly because that organisation is also in the business of cracking such encryption...
