> I suspect that it might be different in the USA because I've always heard that things worked the other way around here: rich people live in wealthy suburbs and go everywhere by car while poor people stay stuck in the city centers.

Over the last 30 years it's been flipping. working class people with no safety net have been priced out/forced out of cities leaving the wealthy, upper middle class, and poor people.
Swap and paging are different concepts. The VM can page clean pages (mmap'd files, like most code your system is running) from disk in and out all day if it wants, in fact, when Linux is thrashing, that's exactly what it's doing.
> but you damn well can!

That's not equivocation, it's what I called nuance, and mentioned the judiciary's role in managing it. With ethics you can say, "this is a hard question," and leave it at that; with the law, you must decide. The judge or jury must ultimately decide whether to punish the possible thief or not, and if so, how -- say, by making a decision on intent, perhaps taking degrees into account. Either society decides to shut 8chan down or not; "it's complicated" isn't an option (I mean, it may well be, but a decision must be reached). So whatever ethics is at play, and however complicated it is, a decision on action must be and is made.

And BTW, not every offense must have criminal intent. Traffic violations, for example, do not (in the jurisdictions I know). Murder, as it is defined in many jurisdictions, requires intent, but even without it killing is often a very serious offense (e.g. you can kill through an intent to endanger, and you can kill through negligence, and you'll end up in prison for both).
> I suspect that it might be different in the USA because I've always heard that things worked the other way around here: rich people live in wealthy suburbs and go everywhere by car while poor people stay stuck in the city centers.

For context, cities in the US used to include the rich, but then "white flight" [1] happened.

Then in the 2000's, young (usually more progressive) people with wealth and white collar jobs began to move back to cities, making that statement not really true today. Of course with this shift came the gentrification and rising urban living cost we see today in places like SF, Seattle, NYC, Boston, and many other popular areas in the US.

So your statement would be more correct in the 60's to the late 90's but not really today. Of course the combination of housing density (lower than Europe) and lack of public transport does indeed make cities more anti-(car commuter) than in Europe, which is also why its so crucial to live within the city itself, thus creating the crazy housing markets.

I think living without cars in medium-high density areas is ideal for many who don't want a rural life, but the US will need major restructuring before that's ever possible, and even then it would only apply to select regions like the Northeast/Mid-Atlantic coast, parts of California along the coast, and a few other major hubs like Atlanta, Chicago, and Seattle. The amount of land the US has all but guaranteed there will always this tension in how people live in rural versus urban areas. I find that the polarization is only growing stronger today interesting, as I'm sure tons of political scientists who have spent more time and research digging into the trend do as well.

Not that I would do it, but couldn't someone create a bot to purposely give incorrect results and screw up Googles AI learning machine?
That's actually the reason why I use Gmail instead of switching to a smaller email service - it's "too big to fail," I don't think Gmail will be discontinued for as long as Google exists, even if it became somewhat unprofitable, due to the outrage and class action lawsuits that would result.
It's fun to think of other ways one might interpret the sign in the article's main photo if social convention changed enough it wasn't obvious.

Monopolies weren't allowed to do things that non-monopolies are allowed to do because they would have an outsized ability to harm consumers as a monopoly. But Amazon has repeatedly shown that it isn't harming consumers. In fact, it's pushed other retailers to better the customer experience or go out of business. Should a company be split up just because it's doing its customers good and got too big because... they're doing their customers good and people like that and want to give them their money?
>Homoiconity, code as data, maros and DSLs aren't FP topics, but Lisp topics.

FP discussion outside of the academic context (and especially on HN) before a certain date in the past 1-2 decades were all about Lisp(s) - and to a lesser degree Scheme(s).

Doesn't matter whether that was "really FP" (real Scotsman), that what was was discussed, advocated, and practiced by most as "functional programming".

ML(s) played very little into the discussion, and purity/immutability was discussed but not as the most important thing (rather as the more pure/mathematical version of FP, but not necessarily practical for professional programming, that came later, and Haskell and then Clojure popularized it).

NPP is on it's way to being really handy, but it still sucks that I have to hack things to force NPP for some payments

(ie. CommBank will only use NPP for PayID payments, but banks like Up will use NPP for transfers for a BSB/Account number if the receiving banks supports it, not all banks are fully on the platform yet)

Hey, do you have an email I can send my resume to?
Yes, but GP was specifically stating that no rights afforded by the United States government were trampled on in this case. This is, no doubt, censorship, but some questions are:

- did censoring 8chan significantly limit any sort of harmful behavior?

- is censoring 8chan "right"?

- does this merely hide the problem, preventing an open discussion?

- should CloudFlare, an entity with massive control of Internet infrastructure, really be acting as a moral arbiter? Or do we expect some kind of neutrality from them? Do our expectations matter?
Sadly, as pointed out by Neil deGrasse Tyson, we respond to spectacle over data.

How many deaths per 1,000,000,000 package delivery happen with trucks? Truck deliver is not a zero death thing. I'd even want to see truck air pollution factored in somehow.

If drones have a lower %, we should view falling death boxes as acceptable. Even though it does have a strangely dystonia aspect to it.
"The Windup Girl" by Paolo Bacigalupi has an interesting part of the plot involving GMO food and companies.
Ballot security is a solved problem (but, sadly, I think DARPA knows this, which makes me wonder what’s really motivating this work):

Use paper ballots. Scan them at the polling place for fast electronic tally.

Audit a significantly significant random sample of the paper ballots after the election, and do a full recount if any discrepancy is found.

Prosecute people that violate chain of custody for the ballot boxes. (Give this power to a non-partisan authority.)

There are open problems around tampering with voter rolls; this is done both by state governments and foreign powers. We still need a scheme to make this more detectable (and to invalidate the election when it happens).
The opposite - you can avoid the key repeat delay to type double characters faster by letting go and pressing again, rather than holding it down and waiting.

That's what this is preventing, because the bad keyboards will register multiple key press events for a single press.
Yeah. I didn't really think of it as a bug at first, but I'm glad someone called it that. I wish the system would just kill the browser or low priority processes instead of freezing everything in an instant.

> So you get this ridiculous situation where US cities can point to all these shiny new bus lines and bike lanes as "progress", but absolutely no one can afford the housing needed to use any of that, so on a CO2-per-person basis, we've regressed significantly. And 1990's era cities with it's freeways and parking were often better for the environment on a CO2-per-person basis than 2019's cities are today that lack those.

There's no way this is true. Housing density has increased within cities themselves. Generally things have also become more CO2 efficient within the cities as well. More people live in cities than 20 years ago. If someone in the suburbs drives, it's the same (or less with modern cars). If they use transit, it's less. If they move out of the suburbs or stop commuting, it's also less. Where does the CO2 increase come from?

It's also important to remember that these trends vary vastly depending on the city you talk about. High density cities with good existing public transit infrastructure have very much succeeded and improved public transit, not destroyed it. LA is very much not a good example due to the sprawling nature. I lived in LA for 6 months and would not call it a city but rather 13 connected suburbs. A bus there is indeed a failed project. Heck, even the Expo line they just built to connect the west side is a lot of travel time and not much coverage.
They are just fighting for a living. If you give rural virginians an option they will be all ears.

How can facts be irreverent?

What is special about NYC to ATL? The distance is about 900 miles via road. The land costs alone would reach into the billions, and there are lots of cities in the middle that will require stops, which severely slows down travel time. And how many people are really commuting between both endpoints? And how many would choose a train over a plane?
I gave a separate answer for Perl 6, but as for Perl 5: Yes, absolutely. I think everyone should know Perl 5 if you ever touch a Linux system. It's installed everywhere and gives you the largest power/keystroke for command-line utility. It's more effective to learn Perl than AWK and Perl has incredibly deep Unicode support and what I call 4th-generation regular expressions (pre-POSIX, POSIX, and then the explosion of early Perl/PCRE/Python-re being the first three and Perl 6's full parser engine being the 5th) which, together, make it like the mythical tool it's often labeled as: the Swiss Army chainsaw.

Don't make the mistake of trying to write anything over a few lines in it, though. You'll find yourself in a deep hole trying to use Moose and "experimental" features just to get back to parity with every other modern language, and you'll still have thin if any support for many modern tools (i.e. those that entirely post-date 2010).

I feel like this can be spun as a positive, every street is 3 lanes wide + parking on both sides. So much room to convert for more pedestrian and micromobility space – in European cities it's often either/or.

I work at Scale - I've met a bunch of people that work on our platform, and seeing the impact that it's had on their lives is actually a huge source of inspiration to me. There's a writeup highlighting some of their stories at https://scale.com/blog/positive-externalities - based on my personal experience, I can say that it's not bullshit.
Wow, that's shockingly low. The paper doesn't describe why -- do you have any idea what part(s) are failing so quickly? The rotors, the motors, the battery?

For commercial delivery service, it seems quite clear that we'll need either

1) "enterprise-grade" drones (like difference between consumer and enterprise SSD's),

2) reliable sensors to detect imminent failure before a flight,

and/or 3) easy replacement of failing parts.

I mean, for many hobbyists 100-200 hrs seems like a reasonable cost/benefit tradeoff... but not even close for commercial delivery services.

This is not a technical problem.

There is no amount of technical solutions you can apply that will actually solve the problem.

So far as I can tell, all the other real solutions are ones that are considered inconceivable.

So long as all sides refuse to budge on the real things that could actually solve the real problems, I don’t see this situation changing. At least,not for the better.
I don't think that would work. There's a huge amount of pent-up demand in many markets for real estate, with buyers just waiting for prices to slightly drop. I'm pretty confident the amount of real estate held by China that they could force sale of would be snapped up by local markets without issue.
Most likely not wrong. Simply too early.

Google wasn't a dominant search engine at the time of the Microsoft litigation, and different people were in charge of the Justice Department by the time that it became one.

> Telia, the former Swedish monopoly telephony company did a surprisingly good job at bringing ADSL to people, quite early.

From my corner of Sweden, the privatization of Telia was what helped us - Skanova (the company formed to hold all of Telia's old copper assets) was required to upgrade any phone switching station to ADSL as long as someone would pay for it, so there were a bunch of rural ISPs formed that would do the legwork to gather enough customers to pay for small switching stations to be upgraded that Telia deemed unprofitable.
I'd argue that even the suburbs of Netherlands are super bike-friendly. It's always a reasonable bike ride to the nearest train station, buses fill in the rest, and the roads are setup to be safe for bikers. That's not really the case in most of the US.
Guns are part of the problem, but not even close to the entire solution. And guns are so ingrained in American lifestyle that they're not going away.

I like the fact that common factors are being found. Maybe flags can be raised and preventative actions taken, including temporarily moving guns out of reach of the at-risk individual.

There is nothing wrong with the 2015's size and feel. It does not need to be lighter than that. Losing basics like an internal HDMI port and SD card slot are not acceptable for me as a media professional - period - for whatever tradeoff.

I don't want to have to dig some adapter out of my bag because the manufacturer of the laptops I've used for almost two decades has suddenly gone daft, prioritizing thinness over the device actually functioning, even as effectively as the previous units, that I have ardently supported for years (I still use an iMac G4 every day for cartoons and random drawings in Flash.)

Don't even get me started on the SSD/RAM being soldered to the Logic Board, either - I'm not even sure if other manufacturers are doing this, but to a girl who used to build her own towers from scratch, is not particularly wealthy, but also not particularly poor, and has counted on upgrading her devices for years to get value out of them when she can later afford it - this feels like an actual slap in the face.

I would personally never purchase a personal computer that I would e.g. do development on, that I could not remove the hard drive of myself, even if just for data recovery purposes.
Occasionally we hear about “found” ballot boxes especially around recount time. How do they get lost. Or what does it mean when they say they lost them (and found them). I’d imagine it’s more prevalent than we hear as it seems rather odd if they only disappeared and reappeared in contested elections.
It seems like it should theoretically be viable to add some commuter rail lines following the same rings as the current peripherical roads, and improve the suburb-to-suburb transit experience.

I think multirotors have the capability to be made quite safe. The only moving parts are the rotors, and with higher rotor counts, graceful degradation of flight performance is possible in the case of a rotor-out.

Problem is that most of the components (batteries, motor controllers, flight controllers) are built by and for hobbyists. Motor burns a winding? ESC spontaneously lets the smoke out? Whatever, they're $15 bucks each. The field of "commercial grade cargo multirotor" is still in its infancy. The balance of safety and cost for the components hasn't been struck in the market. You either deal with random chinese components and control algorithms written by intrepid RC airplane nuts, buy very expensive industrial/aerospace grade components, or roll your own solution.
You can’t ban people’s right to be in public anonymously because a few crazies will use it to commit crimes. The solution of banning those measures is nearly equivalent to saying “all humans should be under 24/7 surveillance in public by the state for their own good”
Considering that e-commerce sales only make up about 12% of retail sales in the US, I think Amazon and e-commerce would have to get a lot bigger.

> The first quarter 2019 e-commerce estimate increased 12.4 percent (±1.1%) from the first quarter of 2018 while total retail sales increased 2.7 percent (±0.4%) in the same period. E-commerce sales in the first quarter of 2019 accounted for 10.2 percent of total sales

I don't think e-commerce is the right market. Most companies selling widgets just want to get their goods in consumer's hands. They don't really care how. Amazon makes it easy and does a lot of the work but sets the terms. Otherwise they'd be going after that 87.6% that's not done through e-commerce.

If you put 200,000 per year at a 10% discount rate (interest rate) in the bank, the fair value after 30 years is 1.8m. In other words, a rational person should take 1.8m now vs 200,000 a year for 30 years (at 10%). And this 10% is very very generous, if you're arbitraging between the risk free rate and the equity rate it looks a lot fucking better.
