TFE (Transport For Edinburgh) uses vehicle on-board Wifi to update buses position instead of GPS and it works pretty well. They do offer a global map (https://tfeapp.com/live/) of all their vehicle as well as a mobile app (https://tfeapp.com/) and dynamic timetable at stop (but not all of them). [The API serving the data seems to have an issue today though]

I have worked in support for a well known GPS navigation software and the GPS accuracy is terrible for most consumer devices. You have to spend a lot of money in a GPS receiver to get past this accuracy issue. What Lothian buses (the company I have mentioned above) have done is using something lower tech to replace the need for such an expansive device. And overall it does work surprisingly well even in heavy traffic occurrence (road work, rush hours, etc ...).
Please correct the title; it's editorializing.
Yup. Food trucks in my area (LA County, but not Los Angeles itself) definitely cook in their trucks, but they effectively cluster into what I call "food truck cafeterias", side streets that seem to be set aside for food truck usage.

It's actually pretty convenient, since two streets over from my office there's usually a dozen or so trucks all available on a low-traffic street.
East Wind pays $180/year per person into a fund held by communities that is much like the funds cited in that article, although relatively small. It's not insurance. It's a catastrophic health savings plan. It will pay (for people fully invested 2 years in the program) their costs beyond the first $5,000 for an illness or injury.
Thank you, I was on mobile. @dang can you alter?
It's not conspiracy. It's standard M.O. and it most definitely is propaganda. The chinese do the same thing. When the chinese authorities want to send a signal to another country, their news coverage of the targeted country turns negative. One of the most recent examples is chinese media coverage of south korea after the THAAD deployment.

We've done the same thing here. When relations with the US and China were bad, the news coverage of china is very anti-china. When relations are good, the news coverage turns good ( like the generous, almost fawning, Deng news coverage in the 70s ).

Of course it's the most noticeable or obvious during war time, but propaganda is ever present during peace, it's just more subtle.
I like protobufs. I've only ever used them as a serialization format for save and map files for some C# games that I tinker away at, but I've been pretty happy using protobuf-net[1]. File size is smaller than JSON produced by JSON.NET or using the built-in binary serializer, much less XML. And it couldn't be much easier to use.

The Tipping Point came out five years earlier.

Also, I think it's important to note that these stories are not actually anti-establishment, even if they have such an appearance; they don't offend any powerful interests. In fact, they're often quite the opposite (consider that Malcolm Gladwell wrote an entire book arguing that being disabled or growing up poor or whatever else is actually an advantage! The people most likely to take exception to that thesis do not have bylines in the New York Times, nor do they have the editor's personal phone number)

And the popular “in crowd” will do whatever they can to keep that from continuing.

A second lie to cover up the first lie. Keep it rolling, Bloomberg. We are watching with a smile.
Recently I've read an answer on Quora about why some shop say that they have guaranteed lowest prices. It turns out that the price is probably higher than the actual price, and that's a sign that other shops should follow them, set the same "high price", otherwise, that shop will lower the price and no one win. It's a good read, unfortunately, I can't find the link now.

Any suggestion for a good comprehensive book on game theory in economics?
you're welcome! :)

First and second order diffeqs with constant coefficients are a big deal, you should at least learn that. You can solve them algebraically via Laplace Transforms, the theory is very beautiful.
Oh yeah, there’s still plenty of work to do. But it’s far closer than what I previously imagined was possible, that’s all I’m saying. You can see my HN comment history change over the years.
I am reminded of Knuth's famous TeX, which goes into an interactive mode when it encounters an error, asking the user what to do next; options include inserting extra tokens before the unexpected one, trying to recover and continuing to process the input, aborting, or even opening the editor so you can edit it in-place. I don't know of any other compiler which does this.

Democrats Fear They’re the Wet Rag Party
This situation is in no way unique to food trucks though. I could buy the property next to your restaurant and make it into an exact clone of your place and give away all my food for free until you're out of business.

And yet I don't see anyone out there arguing in favor of laws banning copycat restaurants.

If I can run a food truck and sell food at a lower cost to people who have to stand outside while they eat, and they prefer that over the experience you provide in your restaurant, the customer is not wrong. Good restaurants, by definition do not go out of business.
Whether or not it’s a lie, you would be a fool to think your hardware is safe.
This didn't even cover things like how county and city sales tax can change if you move to the other side of a street. Also doesn't account for the fact that each different level of government (state, county, city) may have different licenses, so you might have a license to sell on one side of the street, but not the other, regardless of zoning.

I've been considering potential targets for "radical deregulation." An experiment in getting rid of all licensing and certifications and just "see what happens." The risk here is too many taco trucks, and some minor fear of food poisoning. Personally, I'd be willing to accept that in exchange for massive increase in consumer choice and greater opportunity for small businesses to get out from under corporate overlords.
Ask HN: Industries to consider as a developer to weather the next recession?
I'm currently on the job market, and one of the things on my mind is I'd like to pick a company that may survive the next economic collapse. All signs seem to point to an upcoming large correction to this bubble economy, and I'd hate to be laid off because of it.

Does anybody consider how "recession proof" their job may be? Any thoughts on what industries to look towards for better job security? Obviously a lot of startups and investor backed companies are probably not a safe bet.

Thoughts?
I hesitate to say, because there's a possibility that even years later many of the vulnerabilities are still there.

However, one that I know eventually got fixed I'll talk about (it makes a great example anyway). When port scanning one of our pieces of equipment, I noticed a strange port number that was accepting packets. I started sending random packets to it and for the most part it ignored them, but occasionally I could get the system to crash and restart.

Turns out, the server had a debug port enabled and active, even in the production build. This allowed you to essentially invoke any C function you wanted, remotely, if you knew the format (which was published in the OS manual)! Very, very bad.

When I reported it, I got a lot of responses like, "Well, this will be on a closed net anyway." and "If they get on this network, there's much bigger problems." Both statements were true for the most part, but still a very dangerous attitude to have. Just because a network compromise would be bad, doesn't mean you should make it worse by neglecting defense-in-depth. And never assume that somebody isn't going to plug an ethernet cable into your equipment that shouldn't be there (this happens all the time).
Because we are guessing at the problem, we don't have complete data.

Many companies are fine with false negatives in their hiring process. Better to pass on a good candidate than hire a bad one.

At least somebody is extending US rail network.

That's the system working as designed by the ruling class. A person under so many personal pressures won't have the resources or energy to force the ruling class into fixing those bigger issues. It's perfect positive feedback to enable the rich to get richer.

I'm cynical too. I'm on a "good salary" but still can't afford my own home, and have made the decision to not have children mostly because I don't like the way anything is headed and don't see any change on the horizon.

When 8 people control more resources than 50% of the people on the planet [1], it's pretty clear that the evil overlords have already won.

I don't know how to fix it but I'm blown away by the apathy of most people towards the disgusting state of affairs.

From the finance sector bailout, which still blows my mind, to justice only for the rich and powerful while ridiculous numbers of people are put in jail for non-violent crime - which is sure to continue because of lobbying by the private prison industry, everyone knows it's unfair but the population has been beat into a feeling of powerlessness and somehow blaming each other and immigrants instead of the ridiculously greedy beyond comprehension 1% who are really responsible.

Everyone seems to be a crab in a bucket harboring secret dreams of eventually being part of the 1% while simultaneously not willing to admit the fact they are struggling much more than they should be with the amount of resources out there, unfortunately hoarded by a very small percentage of people who have successfully lobbied the politicians to continue the status quo.

So no, I don't think you're alone...

Edit: Some people have suggested some useful ideas here to do something about it at a local level. I'm going to try not to be so cynical and think of the problem being too big to fix, but it's difficult.

I have exactly the opposite experience. Mojave is substantially easier on the battery of my 15" 2018 MBP than High Sierra was.

One reason (probably not the only reason) is that Mojave is much better at GPU switching, and manages to quickly and fully shut down the discrete GPU once it is no longer being used. In HS, this did not happen. The Radeon would still be drawing power even when, supposedly, only the integrated GPU was supposed to be active.

I'm typing this on battery, and currently drawing between 6-14W while running Firefox. In HS this would be between 20 and 30W.
Just out of curiosity, how many rust users have run into memory fragmentation problems with long running processes? I love the performance and low memory profile of deterministic/static memory allocation, but without a compactor, I can't see it turning out well with long running processes.

Same here, have tried QC25s and didn't keep them because it made me feel like I had a cold, gave me headaches, and felt like my ears were not equalized pressure wise.

I use concert earplugs now, they are invisible unless someone really looks in my ears, and they attenuate all frequencies equally. This way I can also use them at concerts and they won't ruin the music, just make it much quieter across every frequency.

I love taco trucks, and I'm a pretty picky eater. My probably weekly order is about: 6 tacos asada, no salsa, 4 jalepenos, radishes and extra limes. Maybe a plate of rice. Proceed to cover the taco in deadly amounts of salt and lime. What I can't ever seem to do is find a "street taco" in a mexican restaurant that's near as good tasting.

> So in the face of a known insufficiency of objective measures, and an identified correlation between a common statistic and some identified metrics, it is legitimate to use that correlating factor to help identify better performing school systems which include the as yet unidentified measures until better measurements can be objectively identified.

How do you figure that? The correlating metric only explains the variance it correlates with. But we're already measuring that variance directly.

> How do you think a law would work, which would only allow floor workers to own/operate robots, but not the workers (the CEO/warehouse foreman) that oversee other workers?

I don't think "most voters" who don't see themselves as temporarily embarrassed millionaires would shed a tear if CEOs, business owners, members of the management and ownership class, etc. had their ability to own robots limited. At least after some consideration of what where most labor was replaced by automation would look like. So I object to the idea that such a law would be "a non-starter for most voters."

I'm not a legislator who's spent a lot of time thinking how such a law would be implemented, but you could probably accomplish with some kind of per-capita ownership limit. A CEO could still own robots, but not any more than a pleb to make a difference. They'd have to employ the pleb's robots instead of buying all they need themselves. That gets around the problem of classifying people. There's still the problem of determining the overall number to be rationed, and that probably requires a bit more thought than I have time to give right now. Though part of it could probably be modeled after the present-day labor market.

This happens in the clothing industry as well. I live in Vietnam where a large part of clothes worn in the US are produced. I can buy major name brands anywhere on the street for a fraction of the cost. They even have labels with US price tags on them already.

Repairing electronics is also super cheap here. I went from thinking I needed to buy a new device to just realizing that everything can be repaired since the cost of labor is almost nothing here and the parts come directly from China.

This can actually be used in all parts of life. The struggle is building the model around the problem you are trying to solve.

I sometimes feel like this is the mathematical model for some of the philosophical teachings of Buddha.
