Reading through the crash test procedure, it is astounding how little attention is paid to pedestrians.

1. Front crash test. Procedure: Crash car into stationary barrier at 35 mph. Is also applicable to face-to-face crash with car of same size, going at same speed.

2. Side crash test. Procedure: Slam concrete block into side of stationary car at 38.5 mph.

3. Side pole test. Procedure: Drag car sideways towards a pole.

4. Rollover resistance. Procedure: Compare the cars footprint to the height of the center of gravity.

The biggest thing to notice is that not one of these metrics involves pedestrians. Metrics 1-3 can be easily improved by making a bigger car, elevating the passengers and providing more crumple room. Metric 4 is unaffected, as the track width is increased to compensate.

If a low sedan hits a pedestrian, the pedestrian rolls over the car, having a lower impulse given over a longer period of time. If a high SUV hits a pedestrian, the pedestrian is knocked back, having a higher impulse given over a shorter period of time. Safety ratings need to account for the danger cars pose to others.

I imagine any multi-ton mass moving in excess of certain speeds will be deadly to unprotected soft-bodied organisms. How do Modern cars differ from non-modern cars in this respect? We've added better brakes, back-up cameras and object detection to avoid running into people, hopefully reducing the number of incidents, but yeah you hit someone with a car moving at any appreciable speed and it's gonna do damage.
But ADS-B is catching up and quickly. I understand there are a few additional layers in SXM and the resolution is better when looking at 200+NM. I find SXM weather to be kind of extortion because they use publicly available data and sell it just for packaging it nice.
For selected use cases, self driving makes a ton of sense to me.

example: stop-and-go traffic - instead we could unlock millions of hours of human productivity (or provide entertainment).

example: self-parking and come-to-me, esp in closed garages. Parallel parking is hard for humans and we're poor at space utilization.

example: environments where obstructions are unlikely... airplanes have had auto-pilot for a long time... why not highway 80 in the middle of nowhere? why not trucks queuing to load/unload containers at port (or conference centers) - just drive up your incoming truck, grab your personal effects and take over the next outgoing truck while it queues for hours delivering a load and getting the next load.

There's lots of uses for self driving vehicles even before we deal with the hard cases. But they're not sexy and of course a tiny fraction of the labor savings and freedom-making.

i made a website for renting and selling real estate - worldwide. visually close to airbnb(ie. big map on the screen) and quite unique filtering mechanism for the ads(i've yet to see anything close to it). essentially the point was to connect buyers and sellers directly because i think real estate agents are just leeches that have no place in 21st century. it was completely free and the goal was to sell ad space. it had not only homes and flats but warehouses, offices and anything else you can think of. one of the things i made point of having was exactly what we are talking about - a rentable desk space. unfortunately, these days, these types of projects live and die with how much money you are willing and able to put into advertising. it is not like in early 2000s or 2010s where a good idea could make it. today, everything has been done and everything has top players(whether service or software). so innovation won't do shit anymore. your success is solely based on ads and getting the name out there(essentially brute-forcing your way to the market). so in the end i killed the project.

though one thing i began working on was my own map tile rendering. i had a free provider(since google and others are insanely expensive for this specific type of project) but i wanted to make my own, for fun. and recently i quit working on a one of my big projects so with a ton of free time on my hands i am thinking of trying again and relaunching the project.

It seems madness to give your card to someone to take off somewhere. In Australia they either bring you a terminal to touch at the table (for a fancier place), or you touch the terminal on your way out (for a casual place).
All of those are benefits that come from high density living.

But while they might say they like those benefits, most people will choose the benefits of low density living, such as more space (quarter acre lots with detached garages and front and back yards and 2,000+ sq ft interiors). Not to mention the benefit of being able to segregate children into different schools by socioeconomic status, by restricting different incomes from living in the same school district via zoning laws requiring large lots and expensive properties, which also leads to unfeasible public transportation.

Sandstorm.io serves each session of each document on a different subdomain, which yes, isn't an all-around "secret hostname" (access control is not managed solely via this strategy, of course), but it defeats a lot of possible dangers or ways to tamper with an app.

It would be extremely prohibitive to have to request a certificate for each session of each access to a document, before even discussing the rate limits of Let's Encrypt.
Sirius is the only decent music discovery service for me since there's some actual human curation going on (at least on their main channel lineup). Spotify is nice when I have playlists prepared and ready to go but that takes work and I get tired of most of my playlist content after a week. Discover Weekly is garbage, and Google Music's version was far worse. Never tried Apple music.

But I've also noticed the repetition on SXM but I've settled on 3-4 channels I like so I switch between them to combat staleness.

That's the problem, isn't it? How can we decode a theoretical alien transmission without transposing our own sense of meaning onto it?

It's like the X-Files episodes where they find the aliens are using encodings that were designed in modern history by humans. Binary (as if there is one standard binary), bar codes... These scenes are supposed to be huge revelations, but for any sort of programmer or engineer, they seem silly. Which wouldn't be so if they made a point about how the aliens are intentionally using our encoding systems, but that's not how it's presented.

Not hating on the X-Files though, that show is awesome.
I agree the web interface is absolutely horrible. I use the desktop app. They allow you to export html from there and preserve the nested document structure (the main feature imo). I've seen writeups about people building nocode apps on notion so I think their idea might be to create an ecosystem where they can ignore respected conventions.
Is your market the set of businesses who don’t want google analytics on their pages? Won’t that be narrow? I imagine most small businesses don’t care and big ones won’t trust you over google? Genuinely curious.
I agree that Santana Row is particularly well done... but I think the author is reminiscing for something more like downtown Palo Alto. What he misses is a few things:

a) Palo Alto can hold onto its old town feel because it’s literally the epicenter of Facebook, google, sand hill road and Stanford university. Some random town in Florida isn’t going to have all that.

B) in places like Florida, Phoenix, Las Vegas, Houston, etc, it’s simply not feasible to constrain parking when a good part of the year no one wants to walk a half mile or more to get groceries.

There are other ways for places to be nice and not look like an early 1900s town center... I’d submit Austin as an example: it’s totally car centered but has lots of intriguing and distinct neighborhoods and plenty of variety while also being quite suburban and housing quite a lot of strip mall retail.

The small downtown can also be very restrictive and expensive for lower income families. For example, in New Jersey, and eastern PA there are quite a few quaint little towns. Oh sure their town centers are full of small restaurants and dog grooming, pharmacies and banks, but conspicuously absent are grocery stores. I know of whole towns with 10-40k residents and not one grocery store. It’s worse in places like Chicago where lack of access to quality fresh produce has been linked to higher rates of crime.

These small towns create high rates of NIMBY-ism and while they do retain their turn of the century charm, I would suggest that it’s just as Hollywood as the new urbanism but in different ways.

I think we can all agree strip malls probably weren’t the best invention and new urbanism isn’t perfect but at least developers are trying to do something appealing rather than just put up another crappy building with nail salons and vape shops.

I see this stated often, that humans are unpredictable drivers. What's the proof that automated systems will be predictable? They too will be dealing with a huge number of variables, and trying to interpret things like intent etc.

Banks and credit card companies sell all of your transaction data for similar analytics purposes. Do a few google searches for "mortgage refinancing", then click a few blogs, and watch as you are followed by mortgage ads for months. Kenya is less formalized, so they derive the data from phones rather than a backhanded way via your payments history.

I'm not defending this practice, just letting you know that the same thing happens whether you are rich in a developed country or poor in a developing country.
That hasn't been the case for a long long time. Especially reposting turned it into yet another spammy service full of promoters. Additionally, discovery is terrible.

There used to be cases of people being discovered, im sure. But a lot of it is not quite the rag-to-riches story they make it seem, especially your example of Billie Eilish.
It was a mistake, people make them all the time. Mistakes in cars kill people, and you don't need to be driving a Tesla to see that.

Frankly the whole point of automated control is to reduce this kind of mistake fatality, and... I mean, it's working. This was a tragedy for sure, but it was also fully two years ago. These events haven't been recurring, it's likely the specific proximate causes have been addressed, and by all reckoning these systems (while still not flawless!) are at or above parity with alert human drivers in terms of safety.

Basically, I read the same facts you do and take the opposite conclusion. People make bad risk/reward decisions all the time, so we need to take them out of the loop to the extent practical.

How so? If it had an FM tuner, you can use an inline modulator.
>nobody to hold accountable

Well, one of the issues is that someone more or less has to be held accountable. And that someone pretty much has to be the manufacturer. No one is going to hand over full control to a vehicle and accept the responsibility if that vehicle commits vehicular manslaughter because "software isn't perfect."

It's actually an interesting legal situation because, other than maybe drug side effects, there aren't a whole lot of consumer products which, properly used and maintained, sometimes randomly kill people and we're OK with that because sometimes stuff just happens.
Ask HN: What tags do you give your AWS resources?
I am primarily interested in general naming conventions (tag:Name) for resources and additional tags when accounting for multiple regions.

For instance, do people "roll up" region/service/environment/instance into a single "name" tag ? This seems ideal for high-level reporting but also verbose and clunky:

e.g. "west1-ec2-prod-apiserver"
MWC hangs by a thread after Nokia, DT and other big names back out

> is the insane amount of PR, politics and marketing talk by people who have ABSOLUTELY NO IDEA

I have seen this too much. People who have a deep understanding of how things work are busy learning and doing. People who can spent their energy with politics and marketing can do it because they are not busy learning and doing. I which there was a solution for this. Corporate IT departments are particularly full of this.
Breakpoint logging sounds like just using conditional breakpoints with a console.log wrapper around the expression, which you can do today. Not saying it's better or worse, but if you need that functionality in Chrome there's your solution :)

This is the 2nd day that an HN post is just a link to a Wikipedia page (yesterday it was the page about the COVID-19 whistle-blower doctor).

It feels obnoxious, expecting the reader to know the context behind the title.
No it sounds super disgusting. Personal data capitalism rearing its head in the third world and smaller, developing nations and the complete ethical bankruptcy of these purported interest rates is disgusting.

(Also fwiw this is the second comment of yours I had to vouch and Unflag, and I wonder who is doing this and why).
I wondered about that. Back when my Air was still running macOS I setup netatalk on a linux server so I could point Time Machine there. But every few weeks I got that message and had to repair my backup. I always assumed it was some issue with netatalk or my configuration. Eventually I gave up and used an external drive.

Thank you for sharing this "Extended Mind" concept, it is mind-blowing -> on an arbitrarily contained mind inside a skull to keep collateral damage to a minimum. In the mind experiment of Inga and Otto they use a notebook to extends Otto's mind and claim it is so because "it is constantly and immediately accessible to Otto", can we say the same of the Internet? Does it extend our own minds?

> result length dependent operations: to calculate a mean in this case we have to pass the string “mean” to transform. This tells pandas that the result should be the same length as the original data.

g_students.score.mean()

has the same length as using `g_students.score.transform('mean')` but the result has different values!

I think that is a great point to add to you very interesting article. I wouldn't know which of the two operations is correct to use, and I would not notice anything wrong, or odd with either method in a code review, so this is ripe for adding wrong results in a production environment.
Yeah, I'm looking at getting one of the cheap teaser receivers at BBY and then activating it on a Privacy.com card or a giftcard or something, so they can't pull that even if I forget or am unable to navigate their cancellation hoops.

> If any people with aphantasia are in this thread, are you able to "simulate" any of these experiences?

No. Memories are like non-verbal propositional knowledge. You know what happened, you can articulate connected facts about it. But the idea of “hallucinating” a visual memory is absolutely foreign to me. You bunch of crazy people actually see things that aren’t there, in your mind’s eye?

Strong no, but I fail to see the relevance. I’m atheist for entirely unrelated reasons.

The person who originally mentioned those percentages and started this comment thread (and since edited it down) said low/medium risk.
Why should insurance be more than today? Unless you're arguing that safety systems in other vehicles make you driving one without those systems more dangerous.
And even if you do manage to solve all the problems you listed in a single walkable area your problems are only just beginning.

* You have to have commercial and residential delivery infrastructure which means roads that reach individual businesses and enough space to park them, and unload. This doesn't immediately mean vehicle sprawl but if the roads are already there...

* You have to support garbage trucks being able to reach every business and residential building. I love the idea of having pooled shared trash areas but in practice it just means more litter and worse public health because you've just increased the cost of disposing of rotten food.

* There are going to be people that actually want land for their hobbies like gardening, woodworking, smithing. You can push them to the suburbs but they'll still need to come into the town center to buy things and more area to cover means higher public transportation costs and lower ride density.

* You have have a system to deal with the fact that people's lives change. A family whose jobs were both previously local and close are now split and aren't walkable.

* Housing a school districts are 'sticky' to families because people put down roots in a place.

* The town needs to bring in outside money -- really no way around this one which means you need some industry (which if your lucky is walkable and fits in with the small town vibes but probably isn't) and tourism / business travel to support secondary industries who are coming in with ... cars. And since not all industry is office jobs that can be done anywhere/remotely you'll probably need to push them outside the town square and figure out work transportation.

* You'll need a public transportation system which is almost surely going to be vehicle based because buses are cheap and flexible.

* You're also gonna need a way to get people to and from the nearest airport. You could try to get a small airport just outside of the town within range of your public transportation but most likely you'll either need private cars or a greyhound style system.

The dream of self-contained communities is the "movie-set" idealism. It's like we're ignoring all the factors that lead to the current state of things and pretending that they're just not problems anymore.
I have a strong suspicion this is why they are so down on Huawei, to the point of outright leaning on the British government.

It is indeed surprising to me that people can tolerate the low bitrate sound. I would consider subscribing but I can’t stand to actually listen. Do subscribers get a higher bitrate? My impression is that it’s a limitation of the satellite signal bandwidth and the number of channels they cram into it.

Yeah, I was just thinking of switching away from Mate on my laptop yesterday because of the external monitor experience. It was struggle to get it working, and once it does it is nowhere near seamless.
This issue can easily be fixed by switching from delta LOC to the size of the git diff (number of lines changed). The big problem with this strategy is the huge difference between 10 lines of carefully engineered algorithm code and 10,000 lines of blah API calls and boilerplate. I can write API calls and boilerplate as fast as I can type.
Maybe the section was called something else, but the publicly available info on the listing certainly didn't ask me to lie to neighbors, authorities, etc. Whatever section it was could only be seen after booking. It's true I should have inspected those details more closely after the initial booking, but it was something that AirBnB shouldn't have been facilitating in the first place. Shortly after I complained, the listing was deleted and recreated, and later deleted again (whether on the host's part or AirBnBs, I do not know)
Well, in this case it's not about competitors, it's about newspapers and publishers wanting to extract money from Google for displaying the <title> attribute of their website.

Good questions, thanks for those.

When working alone on the project I feel like the momentum gets lost sometimes. Sometimes I'm busy building a feature that takes a lot of time and don't have time for other features or bugs. Or when working on marketing there is no time to build new stuff. There might be a future when I'm not coding at all and only responsible for the other aspects of the business. That's why I'm already hiring a freelancer.

Normally the freelancer would work 1 day a week which is about half the time he worked in January. Not sure if I would consider it as essential though, because I can always take over and do it all myself. But I'm not planning to do it all myself.

Freelancer costs will not scale as much as traffic would scale. As the work of the freelancer is related to new features. Most of our systems can handle a lot of traffic and if we can't anymore we need to add more hardware (which will be recurring) or write some software (which is not recurring).

As for recurring gross margin. Would a list/graph of recurring costs be sufficient? Combined with the monthly recurring revenue of course.
