Impressive feat by Waymo, though it could have been 100-200ms faster had it noticed not only the change in trajectory, but also the jerky motion that destabilized the scooter.
For a truly superhuman performance, it might even register the brick and anticipate the scooter's accident.
There were a lot of aspects of this talk that I thought were really great. The willingness to try something unscripted, diving into the code repo live (e.g. to show where fuzzing is used), and the discussions of the reasoning behind the design choices. Great job @xiaq. This really makes me want to try elvish out, and I usually am quite skeptical of new shells.
haha I can't present nearly as well as yourself but maybe one day.
It's not easy to present though. I know on HN we see a lot of very clever people give some well executed presentations and it's sometimes easy to forget how much preparation and courage it takes to perform like that. And it's great to see how engaged people were with the content too.
Sorry, this is less of a question and more just comment of appreciation.
Haha, I've always enjoyed being at the end getting less attention from teachers. If the data merely shows a correlation, it may as well be explained by us at the end being under less pressure.
Most useful is relative. The book dealers who gave me my first ever contract for an automated leaflet generator that generated customized leaflets for each dealer would consider that the most useful. It's been over a decade and they still use it every day. Some other projects that come to my mind:
- an open source OIDC authorization and identity server (Ory Hydra and Ory Kratos)
- a system that uses computer vision to track food waste in industrial kitchens, helping them understand and minimize food waste
- a live milk quality estimator for a milking robot
- a browser extension called memorize. I wrote this reusing code from another contract I did while still in secondary school, and I'm mentioning it thanks to a user named lush berry who wrote "literally the most helpful thing i ever found on the internet. it helps me memorize stuff even when i'm procrastinating which is amazing. however, i have a lot of suggestions, does anyone know how i can contact the makers of this extension?". I wish I had the time to listen to these users and make the changes they want.
Because my card was issued by MasterCard, not Amazon. The technology between the card reader and my card account is determined by MasterCard, and in theory MasterCard don't need to give Amazon any identifying information to process a payment.
It's been a few years since I've looked at any of this, so please forgive me if I'm out of date. I figure giving you information that's probably current is better than what you're getting right now (no information).
The protocol between the card reader, the payment processor, and your creditor is determined by your creditor, but the details of the implementation are not. In the same way that a website can do whatever they like with your credit card information once you enter it, the card reader can do the same. There are some laws and industry best practices intended to protect your card information that vary by region, but your account number, name, and card expiration date are exposed to the merchant even when using EMV. (see https://www.eftlab.com/knowledge-base/complete-list-of-emv-n...)
EMV is designed to provide PIN authentication to prevent the use of stolen cards. It doesn't guarantee an end-to-end secure protocol for each transaction (because that wouldn't work offline).
One of my relatives, uncle George, was fired ~30 years ago. His most valuable possession was a gold watch that baroness Coudenhove gave to a her maid 2-3 generations earlier. I don't remember who exactly the maid was, but she was somehow related to the family. In order to raise funds to buy his own tipper truck, George went to the Charles Bridge in Prague and found a buyer for the watch, a German tourist. The money was at least 50% of the price of the truck. These were the first steps on a long journey leading to a successful business.
This was in a country with high inflation that's just gone through a regime change. Did he get a good price for the watch? Yes, at that moment, the truck was more valuable than the watch.
Underappreciated point! What makes jewelery a good store of value? Value:volume ratio.
Three trucks full of wet concrete have value too, but they're a helluva lot less convenient to bring with you in a bag on the run.
Jewelry is (a) small, (b) valuable, (c) widely exchangeable for currency or goods.
Sure, you're going to take a haircut on the price, depending on how screwed up your immediate environment is, but there will be some buyers at some non-zero price.
