> 5.6 seconds before impact, it classified her as a vehicle. Then it changed its mind to “other,” then to vehicle again, back to “other,” then to bicycle, then to “other” again, and finally back to bicycle.

System can't decide what's happening.

> It wasn’t until 1.2 seconds before the impact that the system recognized that the SUV was going to hit Herzberg

System is too slow to realize something serious is happening.

> That triggered what Uber called “action suppression,” in which the system held off braking for one second

A hardcoded 1 second delay during a potential emergency situation. Horrifying.

I bet they added it because the system kept randomly thinking something serious was going to happen for a few milliseconds when everything was going fine. If you ever find yourself doing that for a safety critical piece of software, you should stop and reconsider what you are doing. This is a hacky patch over a serious underlying classification issue. You need to fix the underlying problem, not hackily patch over it.

How is this not the title of the story? This is so much worse than the "it couldn't see her as a person, only as a bicycle". At least the car would still try to avoid a bicycle, in principle, instead of blindly gliding into it while hoping for the best.

> with 0.2 seconds left before impact, the car sounded an audio alarm, and Vasquez took the steering wheel, disengaging the autonomous system. Nearly a full second after striking Herzberg, Vasquez hit the brakes.

And then top it off with systemic issues around the backup driver not actually being ready to react.
> The core business is very profitable. Loss-making is happening in their less mature product categories and expansion efforts.

Not really. It is true that in their non GAAP accounting they broker out revenue by segment and showed that "Rides" made a profit of $631M but they also include categories for eats, freight and other bets that lost money.

But the kicker is that they introduced a category called "Corporate G&A and Platform R&D" which lost $621. If you look at this category which includes

> "Corporate G&A also includes certain shared costs such as finance, accounting, tax, human resources, information technology and legal costs. Platform R&D also includes mapping and payment technologies and support and development of the internal technology infrastructure. Our allocation methodology is periodically evaluated and may change."

SO basically they are saying Rids is profitable if you don't need to have a business to run it, ie no lawyers, HR, execs, payment systems, cloud infrastructure or employees to develop code.

TL/DR rids is profitable if you ignore the cost of running the Rides business and only look at the income that it brings in, which is true for any business that has income.
Because (s)he is not correct. "Adjusted EBITDA" =/= EBITDA. Uber rides are only profitable if you use their bullshit non-GAAP numbers. If you do the accounting in the proper way they are not profitable.

Run Docker Containers with SystemD
I have been using Godot since recently and I sincerely think that Godot has one of the finest programming experiences, not only for games, but for any kind of visual programming.

I sincerely recommend that anyone with a mild interest try it, it only is a 60mb download with no installation needed, it comes with its own text editor and docs, so it comes with everything you need to start tinkering.
Ask HN: New employer asking me to sign a strange agreement
Have you ever been asked to sign a strange agreement that you did not consent to by an employer? I know non-competes are pretty far reaching in an unrealistic way but are pretty much a standard so we kind of give them a pass with the hopes that they won't be enforced.

That said, I was recently asked to sign an agreement that said my company would be able to use my photo, biographical info, or my likeness in any way to promote their products without my consent. Has anyone seen something like this? Were you able to push back against it?

Big O – A Perilously Practical Introduction
Weird that this is being downvoted because Uber has shown no interest in acquiring and managing assets (self-driving cars or even their own cars) which is a completely different business than being a marketer for independent taxis. If self-driving cars become a business it seems like rental car companies would be ideally positioned to take advantage of them.

That's unfortunate. I used to be a tour guide and raved about the awesome need-based aid at Rice. The maximum amount of loans I had to take out each year was maybe $2,500 and my parents didn't have to pay much more than that, and I had a friend whose parents' total annual income was only $7,000 and he didn't pay a dime (and he had a workstudy job in the student pub). However, I also knew someone who had 2 parents with engineer salaries and they didn't really qualify for any aid so his parents weren't excited about him going to Rice compared to a state school since they didn't really get any aid.

No one at Rice has asked for my opinion, and I'm not privy to all the numbers behind the scenes, but I'm surprised they can't be more generous with the middle class since we have such a large endowment. They recently announced a big new financial aid initiative, but I wish tuition could be free again like it was until 1965!

Freedom is the ability to make choices, which means having the power to choose. Great power is a great freedom in choices- and of course that freedom comes with a responsibility- you made choices, you are responsible for them.

And yes, if you have no freedom you cannot be considered responsible for what you do or don't. A slave cannot be held responsible for actions he's been ordered to perform. This might not be "blissful carelessness" but certainly is lack of responsibility.
I've successfully deployed this strategy in the past. I used to run a service off a personal server for a bunch of MUDs. Eventually I didn't want the responsibility of hosting some important infrastructure for them so I sent them the source code and instructions for how to set it up, but didn't hear back from the admins for months.

So I made everybody who used the service see a message saying "this service is retiring, please move it to your own infrastructure" before it would redirect to the actual service. I gradually increased it from 1 second to 30 seconds and eventually the admins set up the service on their own infrastructure.

Empathy is essential. And his con was a truly remarkable con during a run of remarkable cons, which attracts attention. But I have trouble sparing much sympathy for someone who has 10 digits to tide them over while they figure out what's next.

I was hired at Uber with the promise of 49$ a share, and boosting that it will go up to 75 by the time of IPO. Naive me at the time didn’t research more on it, but these were just some numbers thrown at me in 2015. I will never trust a recruiter offering me snake oil again.
That said, I left after a year and a day, and this price makes my compensation close to less than new industry hire.
Fine with me :).
After reading your review, lack of tags and "Electron" were you biggest complaints against Typora. Typora is not a notes manger, and reviewing it for what it's not trying to be, is unfair. As for electron, despite the perception of being a hog, Typora's resource usage is about 150MB in RAM and 0.5% CPU when idle. I think your modern MacBook pro can trivially handle that.

In my opinion, Typora's advantages are:

1. WYSIWYG markdown. I don't believe iAWriter is WYSIWYG. While that's ok for developers, Typora is more widely usable.

2. Extensions: from Mermaid, LateX, sequence diagrams to code highlighting, to export to ePub (via Pandoc), Typora is a lot more versatile

3. Saves files as text (.md) and assets, easily searchable via OS. Highly portable

4. Cross platform (Mac, Windows, Linux)

• The premise of the app is that you type or paste in Markdown syntax, and see the corresponding rendered output in the editor (except when the cursor is inside that area). As asterisks have a special meaning in Markdown, you should expect to see bold text (rather than the asterisks) when you type or paste something like asterisk-asterisk-foo-asterisk-asterisk.

• The intended meaning of ten asterisks in a row is hard to predict from the Markdown syntax definition. Their rendering as two bold asterisks seems to be not what the majority of Markdown converters do, but according to Babelmark it is consistent with a few, including the original Markdown.pl: https://johnmacfarlane.net/babelmark2/?text=Asterisks+on+the...

Personally, I think using automobiles as a blueprint for autonomous transportation is horrifying and preposterous. The first auto I know of went 10mph in 1886. Engineers have had over 100 years to iterate on the concept yet people are still dying. Somehow, Ubers and Googles think they can distill this kind of refinement into a decade or two of software "engineering". Insanity.

We should focus on transporting goods and services autonomously at a fraction of the speeds. It should be about efficiency and impact, not getting one human from A to B.
Blockchain (ie. Ethereum) is, overall, a reducer of monetary and non-monetary transaction costs.

Example of reduced monetary transaction costs:

The current Ethereum gas price for a token transfer is $0.04 (https://ethgasstation.info/). Operations on Ethereum are relatively inexpensive and will become much cheaper with Ethereum v2 in a couple of years. The cost of Ethereum operations is orthogonal to the value of the money being manipulated. You can transfer $100M for $0.04.

Example of reduced non-monetary transaction costs:

Say you wanted to launch an eBay-type app with a single market for a dozen countries. Some customers may bring Euros, others Swiss Francs, some USD. Each market auction selects a currency from a whitelist. All bids for that auction must be in its selected currency. On Ethereum you can bid Swiss Francs which will be dynamically exchanged for USD. Unlike using your VISA for forex, this currency exchange is at the same price that whales and banks get; you pay no spread fee for being an end consumer. The non-monetary transaction cost part is that this Ethereum-based currency exchange API can be permissionlessly integrated in an afternoon.

2nd example of reduced non-monetary transaction costs:

https://www.pooltogether.us/ is a no-loss, audited, provably fair lottery built on Ethereum. The way the lottery works is -- you always get your money back, but your money bears interest during the lottery period, and all the interest goes to a single lottery winner. So the cost of the lottery is the time value of your money. PoolTogether is built on other Ethereum projects, that's why the lottery proceeds earn interest. The non-monetary transaction cost part is that PoolTogether is able to access interest-bearing deposits as easily as you can use jQuery. Also anyone in the world can participate - reduced cost of being in another country.

That's the funny thing about Billions-with-a-b: normal thinking about money and value just doesn't work IMO.

The Vision Fund is going to lose ~$19 billion. But Masa Son still controls over $80 billion. That's more wealth and power than almost any human being will ever have in history, ever.

At that point the numbers don't even matter. Maybe Neumann took Masa Son for $50 billion. Who cares? A person can live in the USA for their whole lives without working on as little as $3-5 million. Throwing billions around like this, especially when it's digital/paper money in the form of stocks and big corporate deals, really puts the absurdity sprinkles on top of this whole turd bowl.

It's this kind of thing that makes people lose confidence in the system. Most people out here are sweating medical bills in the low $10,000's, while the news is talking about billions being gained and lost in the span of a few weeks - so fast it makes you wonder if that amount of wealth really even existed in the first place.

How much has to be "lost" between digital transactions before the numbers become completely meaningless? A trillion? A quadrillion?

Not everyone experiences conscience in the same way. He might not even have one to torment him in his moments of solitude.

And when you say "mildly unpleasant", I can only assume you mean that for the rest of his life, his sole source of genuine unpleasantness will be from his own psyche. Because he'll be worth a billion dollars. And while money can't buy happiness, it can remove every last speck of annoyance, peeve, and inferior market option.

This failure will be easier for him than for most other people who fail far less spectacularly.

Even if a thousand people make it their life's mission to persecute him at every moment of the day, he still has approximately a billion dollars more than all of them put together. All he really has to worry about is avoiding Saudi-controlled buildings and territories for the rest of his life.
