And “journey” comes from the Latin diurnum, for day, which also has the same root as per diem.

Time (and distance!) are money.

The Angles and Saxons and Jutes had a similar culture before they colonised England.

> At a mere (say) 240mph, 5 miles is 75 seconds.

The world record holder for a quadcopter drone is 224 mph. Not many drones can beat 100 mph.

According to one article I found Amazons drones can manage 50mph.

100mph is probably around the top speed for home built FPV quadcopters with 5 inch propellers; that's neither uncommon or expensive. Amazon's drones are probably built for efficiency though so they will go slower than that.

5 miles at 50mph would give only Amazon 360 seconds to fix the bug that caused the first drone to crash. Or figure things out enough to get the second drone into manual override mode.

Neural nets in drones are only used for object recognition. Beyond that, drones (and other autonomous vehicles) aren’t doing any sort of reasoning or decision making, they follow rules, they’re just robots.

Although I hear that Tesla is thinking about using AI for decision making as well, which I find quite scary. Frankly I think it’s safer if vehicles don’t have concepts and intelligence, and just follow the rules.

Whenever I see someone say AI without specifying what branch of AI it is(CV, NLP, etc), I can’t take anything they say seriously.

Also, It’s sad to see GOFAI being called “rules” :)

Self extracting executables, (zip files with the decoder included) have been around for decades.

Excel, Word and PDF readers weren’t properly sandboxed.

Sum(x) is a better example. Indexing x won’t help when you need all the values.

There is considerable evidence that people who live alone are at greater risk of hospital re-admission, probably because they are less able to care for themselves properly.

Evidence shows that violence and other bad behaviour among boys is highly concentrated around the 14 year old mark. Statistically, older boys (16-18) are a lot better behaved and can act as a moderating influence.

Is this sort of thing as common in US colleges as it is portrayed in movies?

My experience of university (not in the US) was that by then students had grown up, and there wasn’t any bullying going on that I saw. Students were treated as adults, violence was dealt with by the police.
