Well, I was driving home yesterday, and the integrated navigation map of my car was randomly rotating 180 degrees every few moments, just long enough to be noticeable on-screen, but then flipped back. I have no idea why (something in the compass integrated in the car? was GPS being hacked?). But the thought I kept having was "If I had a self-driving car, what would be the impact of this?". All I could think of was ho…

A proper self driving car will have more signals for orientation than just the compass.

Exactly, sensor fusion is so important.

"This Tweet has been deleted" -- does anybody have a mirror? Maybe @dang can update the main link to that.

https://threadreaderapp.com/thread/1581643415850098688.html https://archive.ph/cToUl but foone doesn't like the orange site so we probably shouldn't link (another advantage to running your own site, you can make refers you don't like see goats) https://threadreaderapp.com/thread/1582089029096382464.html

As I and others have previously pointed out [1] foone uses they/them pronouns and feels particularly frustrated when their posts get featured on HN, because users here seem unable to honor this simple preference of theirs. It looks like they deleted their tweet out of frustration with todays latest round of misgendering. I hope people on HN will learn to respect all members of our community. Yes that involves not ass…

Some military trucks are designed the opposite way on purpose - because they’d rather have no brakes and be able to move than be stuck on the battlefield.

That’s a great example of how you always have to design for a context.

I know what you meant. I was implying that a 101-105 key keyboard has not been standard for a decade or more. I would be willing to bet that none of the ten most popular/best-selling computers in the country for the last 5-10 years have had a key that says “break”.

The 10 most popular/bestselling computers in the last 10 years definitely would include the Dell optiplex line that comes standard with a full size keyboard that has a Pause/Break key.

Nope, they’re all laptops.

Not in the US. US trucks are built using standard truck parts, including off-the-shelf air brakes that fail safe.

they didn't always fail safe. I remember a house at the bottom of a steep mountain grade that got plowed into on a regular basis especially during that time. EDIT: hmm... seems freezing might still be a way to cause failure?

Failure at the bottom of a steep hill is a different type of failure caused by brake fade due to the brake drum swelling with heat as the truck goes down the hill.
