You may be interested in a recent episode of the 99 Percent Invisible podcast (https://99percentinvisible.org/episode/atomic-tattoos/). The title of the podcast comes from a Cold War program carried out in 1952 in which students could opt to receive a small tattoo of their blood type, with the goal of creating a "walking blood bank" in the event of a disaster requiring mass transfusions.

Related to your question, the episode also explores the history of "duck and cover." It turns out it's there is some credibility to the technique. In September 1945, the US sent a team called the Atomic Bomb Casualty Commission to Japan to research and interview survivors of nuclear blasts. They located survivors just a few blocks from the explosion epicenter, who had been sheltered by concrete basements. They also heard stories of people who were killed just by shattering windows and falling debris. With just some ability to shelter, survivability might be higher than you suspect.

Restaurants I book through OpenTable almost always call to confirm I'm coming; other reservation methods usually don't get that, except at the most expensive "special occasion" kinds of places.
Yes, but it took GitHub 10 years to make small private (i.e. side project-friendly) repos free.
Which is another great reason to get cars out of cities. The best time to be walking in a city is during a heavy snow storm when the cars are gone. Bikes and electric buses are fairly quiet, keep those.
Getting to El Segundo is tough, and will be improved in a couple of years, but when you worked in Culver City you could have taken the red to expo line, it would be a little over an hour on that route, depending on how close you are to the stations.
My first thought was this book. But the book treated this idea almost tongue in cheek. (the writers in the book were treated like royalty) And as a teen I thought this was a good idea, but as an adult I feel this is a marketing gimmick. :P
Which is a large part of why lunches tend to be cheaper and happy hours exist. (Though the prevalence of happy hour food deals seems to vary a lot by location.)

OTOH, people don't necessarily like to have their noses rubbed in the fact that there's only a loose correlation between meal price and the restaurant's variable ingredients cost.

There are a number of otherwise excellent restaurants in my area that have stopped accepting reservations entirely and switched to a "first come, first served" model.

I stopped going to those restaurants because of the number of times that I've shown up only to be informed that the wait list is over an hour long and we've ended up having to eat at the greasy spoon down the road because we're hungry and have run out of time.

If I can't make reservations (directly with the establishment -- things like OpenTable don't count), I won't eat at the establishment. The gamble isn't worth it.

With all the sensors on an aircraft, obviously the ones physical exposed out side the aircraft are more likely to malfunction, but I’m sure there are many unexpected behaviors that have yet to be discovered when other sensors fail too.
Not sure we have a propensity for punishment here, at least not in a way that stands out from anywhere else. The way I see it is we have a propensity for profit, and some people figured out that punishment is easier / more profitable than rehabilitating people (not counting any negative externalities on the entire society having to deal with having a sort of underclass of criminals).

And I would almost guarantee that someone made money off of establishing a contract to sell such tracking devices to the state, to then sell/force them on bad drivers.

I agree that this move is articulating enterprise customer demands rather than demonstrating greater software freedom. I don’t view this as unfortunate though. Slack is a productivity and collaboration product versus a utility like a low level database or encryption method. As such, many users and businesses want to pay for support, added features, hosting/availability/backups. It is better to have someone having to pay Slack a lot for power features than have a bunch of targeted ads in Slack. The buck stops somewhere.

> people with wisdom teeth just have surgery to remove them

I think this is mainly a US and Australian thing: https://www.sciencealert.com/no-you-probably-don-t-need-to-g...

In Australia it's particularly bad. During a checkup my dentist casually mentioned how he'd be removing mine (at a later date), even though he could provide no reason for doing so. The cheeky bugger just assumed I wouldn't ask why!

Since then my trust in dentists has been further eroded by this Cochrane review https://www.cochrane.org/CD004625/ORAL_routine-scale-and-pol... that concludes with:

Authors' conclusions:
For adults without severe periodontitis who regularly access routine dental care, routine scale and polish treatment makes little or no difference to gingivitis, probing depths and oral health-related quality of life over two to three years follow-up when compared with no scheduled scale and polish treatments (high-certainty evidence). There may also be little or no difference in plaque levels over two years (low-certainty evidence). Routine scaling and polishing reduces calculus levels compared with no routine scaling and polishing, with six-monthly treatments reducing calculus more than 12-monthly treatments over two to three years follow-up (high-certainty evidence), although the clinical importance of these small reductions is uncertain. Available evidence on the costs of the treatments is uncertain. The studies did not assess adverse effects (of the scale and polish treatment).

I know it's a bit of a joke that HN commentators assume they know more than the experts, so just to be clear: I consider the experts here to be the study authors.
People are willing to spend time on the car commute because zoning won't allow you a good job to exist within walking distance of a house. Shopping isn't allowed within walking distance of either of the above either. We are back to square one: zoning won't allow anything other than car oriented lifestyles.

It is a self reinforcing vicious cycle. You can break it anywhere. I recommend started with breaking zoning because it is least painful. If you eliminate cars people who currently depend on cars will be in trouble since they cannot live their life. Eliminate the need far cars is a much slower thing that won't have any noticeable affect for 20 years, but it is a much less painful transition.
I see it less about eliminating cars (though that would be awesome if possible) and more about giving people alternatives (public transit, walking), which you don't have in American suburbia.

Much of the rest of the world has already figured it out. I'm in a "suburb" of Seoul right now. I can get to Gangnam in 30 minutes door to door via the subway (subway ticket is ~$2 each way). I'm a short walk (< 5 mins) to grocery stores, restaurants, coffee shops, etc. It's all apartments here, which is why everything is so walkable. Of course this means less space than a house, but it's quiet and there are plenty of parks/green and a big lake nearby (5-10 minute walk).

Meanwhile back at my parents' house in the suburbs of Washington DC, the closest commercial business I can walk to is a gas station 20 minutes away, next to an ugly car-ridden highway. The nearest grocery store would require crossing that wide road and walking an additional 10-15 minutes through a massive parking lot. There is no viable public transport - if I want to take the subway into DC I need to drive 15 minutes to the nearest subway station (subway ticket is ~$5-8 I believe). Although my immediate neighborhood is very nice in the sense that there are a lot of trees, there actually aren't any parks (unless you count the local elementary school) or businesses of any form, including simple convenience stores (something I noticed is commonplace in most of the rest of the world).

Everytime I'm at my parents' house I'm completely dependent on having a vehicle to do anything, and bored out of my mind within about a week because it's extraordinarily isolating. I get very little exercise because I end up just staying in my house all day because there's little to do. On the other hand I can be in "city"-like suburbs like the one I'm in now and not feel lonely even if I don't talk to anyone because I can just step outside and there are people everywhere, or go walk to one of the million coffee shops nearby that are always packed with people hanging out.

I despise American suburbs. Who decided that the "American Dream" is owning a single-family home in the suburbs? I guess I'm just not enough of a hermit to enjoy that lifestyle.
No can do, not sure if enforceable but employment agreement says all code I write even if unrelated to job is theirs.
As someone in a similar situation, I think you're underestimating the potential economic hit. I own a house in rural Oregon, but I also work and rent an apartment in the bay area.

First of all, my house in the clean mountain air is also at the very edge of the electric grid. I have utility-provided power and telephone, but I'm so far out that the phone company won't offer me DSL at any speed. So I'm stuck with satellite internet, which really isn't suitable for remote work.

Second, almost no one offers a flat pay-scale that ignores your home address. Incredibly, this has meant that so far renting an expensive one bedroom apartment in the bay in addition to my mortgage is a much better economic decision than finding a remote job that would let me leave the bay behind.
I'm not sure that anyone would argue that programming languages are anywhere near human language.

Though the article is in response to allowing CS/programming classes to count towards foreign language credit in highschool, which is a potential way to get more kids involved with programming.

there are a couple pretty core assumptions that make that hard:

read() interfaces expect the kernel to put the data where you asked. its hard but not impossible to coordinate with the NIC to demultiplex the packet and get it into the right place without a copy. almost all of the time you just want to see the data, you dont care that it lands in this particular spot.

getting control flow in and out of the kernel is expensive. target address need to be checked. registers often need to be saved.

things like the kernel firewall take a certain amount of work to determine the packet status

there are lots of mitigations, but at some point you run into a conflict between general purpose multi-process functions and performance.

if you ran your application on a dedicated arm next to the nic I bet you'd see a difference. maybe that shouldn't be so hard.
With today's media motivated by virality, ad clicks and eyeballs, most seem more interested in reporting this as dramatically as possible.

In 2019, we need to wise up to these shenanigans. Fear isn't the only mindkiller. It turns out that Outrage Virality is very synergistic with fear. Our society needs to become very skeptical and notice when something is evoking that particular emotion. We need to view people hawking outrage like we now view medicine shows.

EDIT: If someone has gotten one to really hate a person, really want to harm them, and wonder if they're really sentient, or wonder if they're looking at the same reality, or wonder if they're really human -- this is a big red flag. This is precisely the state of having those in-group/out-group instincts tweaked. Word to the wise! Expert tip: It even counts when one is shocked at someone else's groupthink! Perhaps especially so.
“Unfortunately, substituting regulations for good thinking has the potential to nonsensically stymie progress if done incorrectly.”

One use case I haven't seen mentioned is note-taking. Apple Pencil is a truly amazing device. I use it at work all the time, especially in meetings. It's quieter than typing and because I don't have my laptop open, I'm much less likely to get distracted by slack, email, HN, etc. It's also slower typing, but that may be a good thing because it forces me to mentally organize/consolidate whatever I'm writing.
I did read your comment. I just found it mostly not worth responding to your suggestion, honestly. But let's do it anyway.

""I get that restaurants have to protect themselves against no-shows, and I have no problem handing over a credit card number so that they can charge a no-show fee."

"

Did you ever consider this may not be at all a viable product model, given it's been tried and failed miserably?

IE your solution may not be a solution that works.

If your level of trust is that you expect restaurants to cut corners if you pay up front, i guess i'd suggest not letting other human beings prepare food for you, since they already paid in advance for the ingredients, and so they already have an incentive to cut corners in your model regardless of Tock or not.

Put another way, before you eat, you have already cost them money whether you eat there or not, and whether you use Tock or not. Additionally, basically all menus are fixed price and the tips don't got to the restaurant. So there is no reason people will cut corners more due to tock.
'I started Microsoft as a weekend project and now it's making 1B/mo'

'I started Apple as a weekend project and now it's making 1B/mo'

'I started Google as a weekend project and now it's making 1B/mo'

How the company was started is completely irrelevant to the outcome and it's clearly an 'entreporn' clickbait title.
Gumroad raised millions to get started and it took 7 years to get to the point where they are now. And 350k/mo in revenue doesn't even mean that they are profitable.

If you are an (aspiring) entrepreneur, don't compare yourself to the typical story posted on IH.
Many restaurants have stopped answering their phones.
I'm sure my experience is partly due to my own learned preferences, as well as the specifics of my neighborhood. I know there are nice suburban and rural areas to live, and I hope that with time I develop a greater appreciation for what's here.
Clear, maybe. Mixed glass? Unlikely, since who wants weird looking glass?
It's also a cultural thing. The consumers won't pay a huge amount. They are very used to negotiating for nearly everything and anything.

To make the counter argument, it is rather unfortunate that the way foreign languages are normally taught in U.S. schools (grammar first to make it painful) leads to the cliche of “I took 4 years of French in high school and I can only speak very little.” On this line, make computer languages a foreign language, as schools do a poor job overall teaching a foreign language so that it can be truly acquired. The advantage of computer languages as a foreign language is that picking it up for the learner does not require the learner to deal with frustration and embarrassment in the context of interacting with other people, like they would learning to communicate in a foreign language.

Same way you verify if the person driving a car is the owner. They're legally responsible for the vehicle unless they can prove they weren't at the wheel.

But the real question is, why do you need to verify the person in the first place, unless they are suspected of committing a crime?

I've used it most often to understand a poorly understood piece of a system that is giving the team a lot of trouble. An example would be a feature that went into development quickly and was iteratively developed in an agile fashion. The senior developer was smart and made some diagrams and accompanying prose to describe the system from a high level. However once the system had been in production for about six months users were discovering and reporting strange behaviors. I wrote some TLA+ models to verify the design and discover the under-specified behaviors.

I've also used it in the design/planning phase of a new project. We started writing models for key features and even hooked TLA+ into our CI pipeline. We planned to also integrate the TLA+ models with quickcheck so that the latter could verify our implementation based on the specification. However that didn't get too far unfortunately.

TLA+ has mostly been useful in helping me understand and solve hard problems where code alone is insufficient as a specification.
IRC is worse for me because the people I talk to don't run a bouncer or use irccloud even though I do. Fixing it just for me does not fix the reasons why IRC sucks in this regard.

Ticketing systems like Tock are speaking to that mutual trust. Reservations are another form of mutual trust in the restaurant interaction. You're making a promise to show up and they're promising to hold a table for you. But that's a very uneven trust. You can bail with no consequence to you, while the restaurant gets screwed. I see no problem in leveling the playing field.

Besides restaurants are the outlier. Most experience-based services have a pay-up-front model: concerts, sports games, transportation, conferences, movies, etc. The reason restaurants generally don't is because the cost isn't usually predictable up front for each person. For fine prix fixe dining, it is.
Fine, you can chose to see it that way.

But I do believe that we have a bias towards solutions that punish a particular person.[1]

It's an insurance company, if many people drive badly then you can be sure they've factored it in because they don't lose money over a solved problem like that.

I still don't think we should target bad drivers for extra surveillance, because I value the privacy of the bad drivers too much.

Also valuing the privacy of the bad drivers, is just valuing my own privacy down the road. [2]

> When did spanking your child amount to 'physical violence'?

It's always been physical violence, it just used to be universally accepted physical violence, just like beating (and raping) your wife was. Now it's become less accepted, just as the other two have.
It depends on local details. In most large cities public transit assumes you live in the suburbs and work downtown. Jobs are moving to the suburbs, to get to them means a ride downtown, and then a ride back out. I know of people with a 4 mile commute who drive (why they don't bike is a good question) because they bus ride would be 3 hours each way.
I love this story. In life it is so important that you actually get out and do something. It doesn't have to be big, or elaborate. But it should be important to you. A single python main.py file and Google App Engine! LOL
How does reducing customer choice follow from working backwards from the customers’ needs? Doesn’t the variety in product imply a variety in customer needs? There is not one kind of pro, not one kind of consumer. Shouldn’t Apple be able to offer a wide choice of options and rely on marketing and the 100 blueshirts in every store to guide the customer?

It was confusing to have so many options when tablets and smartphones were new, or when a person could say “I don’t really do computers” and have a successful career. None of those are true now; babies can and do use tablets, middle schools have carts of iPads or Chromebooks. My grandma has an iPad. She calls it her “Facebook,” but she has one.

Simplicity has its appeal, but I trust the market analysts at Apple have a plan for market differentiation with a wide lineup.
