This is already like what many European cities do; the shops and restaurants all cluster in in a pedestrian only zone (in Germany they call it a fussgänger).

I've found these places quite pleasant; you can eat outside without fast loud cars passing by. You can cross the streets at will.

There's usually even a parking garage at the outset, though a metro system or ride sharing also works.

PRISM was an NSA operation, so it's not clear how that is evidence against his claim that the CIA is more responsible with their cyber offense/surveillance than the NSA. If anything it seems to lend even more credence to his point.
Evs are in the long run good but make no mistake that the batteries come with an ecological cost during their use and afterlife. Evs, autonomous cars, and ride sharing are all good but for a major ecological change to happen there has to be a societal one as well. The future with autonomous cars isn't most efficient with everyone having their own car, it's with summonable cars that services own instead of individuals. Much of the benefit of autonomous cars is lost if the vehicles continue to sit unoccupied for the majority of the day. Likely for some time, anything more than a city wide autonomous car network won't be possible as the reliance on networked machines to offload the heavy lifting onto seems too great, much less to get it to poorly connected rural areas.

Society needs to be willing to change how it uses cars in order for a major change to happen.
You can but you there are limits, if your debt is large enough then you can't outgrow it. Just printing money has it's problems, in this case inflation would make safe building materials more expensive to import.

I know people like to bang on about running the economy being different from running your household finances but that only goes so far. The UK is already spending 8% of tax revenue just on servicing debt.
On the other hand, malware would have hit commodity devices much faster. That DMA is begging to be used to root a computer.
Maybe that is the case when it comes to large towns in the US (particularly in the South or the Midwest). In cities, even North American ones, you would have to be totally insane to want to drive downtown. To a large extent, this is because parking is a nightmare to begin with in a downtown core. It is far more convenient to Park and Ride in places like San Francisco, New York, Toronto, etc... even somewhere like Boston or Seattle.
> The problem with holding manufacturers liable is that I'm not sure it's the economically optimal solution

Either you hold someone liable or the effect will just be hiding the risk.

How about just requiring that the use of critical software systems be ensured against malware/failure in general? Seems like we want that anyway, and if we can't find anyone to insure a piece of software, it probably shouldn't be used in a critical system in the first place.

Importantly, it's the users of software in critical systems alone that need to be insured. Neither software vendors nor regular users need insurance. The insurance company, alone, should handle the job of shielding a critical system from the mistakes of software vendors. We need to allow software vendors to be able to make mistakes, or nothing would get made, ever (source: I'm a programmer).

And the insurer would be wise to spend some of the premium on bug bounties for the software they're ensuring (to minimize the cost of failure). In the end, all white hats would end up being employed by an insurance company, helping assess software security.
I don't understand why such a large fraction of our usable land in people-dense areas needs to be consumed by expanses of ugly, dead cement full of giant deadly "creatures" traveling at high speeds, nor why that state of affairs needs to be imposed everywhere on everyone.

In my city - Columbia, SC - we have a magnificent Saturday farmers market that takes up three blocks of Main street. Thousands of people come to eat and hang out with hundreds of vendors for several hours.

And yet.

The cross streets between the blocks remain driveable. As a result, little kids cross the road as SUV's come barreling past. Last week I saw a driver speed through with his hands up in disgust, staring down an old couple crossing the street.

Walkable cities face very real opposition from the norms of society. Despite 10,000 people creating a hive of street life, we still keep cross streets open for the ~100 cars that will use them.

are there examples of American cities who do walkability well? And by well, I guess I mean to European levels.
I think we can learn some things from the way some French cities do things. Most days and most hours of the day, cars can drive on all streets, however, on weekends and some other times, in certain core commercial areas, only delivery vehicles are allowed and these streets become pedestrian-only. I'm okay with that. [as an aside, interestingly, people are in some areas, are allowed to park on the pavement (sidewalks) --which is a bit jarring at first].
I've always been frustrated by how Google's unit conversion doesn't integrate well with its calculator.
I was thinking that eventually we may discover a proof of work that would actually compute something useful instead of burning electricity away. One can hope at least.
It is a continuum, but it is also the case that the most efficient sweet spot for reliability and cost effectiveness changes on this continuum as your scale up.

The web is very decentralized when it started, but it was impossible to find anything, so you would pass along lists of interesting URLs via email lists, usenet postings, etc. Eventually we get catalogues like Yahoo and later search engines like Altavista and Google. The later were a huge step towards centralization of the web and we have not really gotten around this problem.

Email was initially very decentralized (I am talking things like UUCP, Bitnet mail, Fido, etc.) but message routing was a major pain as anyone who remembers UUCP bangpaths can tell you. SMTP is a bit of a sidestep on this path, making addressing easier by moving somewhat in a decentralized direction with direct TCP delivery (and then a half-step back with MX records and centralization of campus-wide email systems.) While email was decentralized it was also open to parasites and we fought the good fight for a while but are now at a point where more than half of all email in the US runs through three organizations because they have the resources and expertise to deliver a good product and control spam -- not exactly decentralized anymore is it?

Git? Yeah, for your small repo. Now try to make that repo open to the rest of the internet and participate in the global source web. Oh yeah, up to github or bitbucket you go. Once again we centralize to scale up and to solve the discoverability problem. Outside of a local context git is almost completely centralized.

Bitcoin? I would point out how only a few mining consortiums control the bulk of the hashing output, but we are now reaching fish in a barrel stage.

If you examine all of these 'improvements' I think you will see that they became more centralized as they scaled up to solve problems with efficiency, discoverability, complexity, and controlling parasites and increasing the cost for attackers. As I stated initially, decentralization for its own sake is almost always a sure sign of an amateur who does not understand the math of network relationships or who has no experience in the field and is just itching to make a dash through the minefield without noticing all of the dead bodies ahead of them or bothering to learn from these lessons.
You're not very good at traveling, sorry. It's considered an important and invaluable skill for travelers to be able to read subway/train/bus diagrams. Going to San Francisco, Seattle, Boston, London, or Munich, if you can't handle mass transit, you're only impeding yourself.
It is entirely possible that language development created a self-reinforcing feedback loop for the development of intelligence. I don't think intelligence and consciousness are necessarily correlated though.
I think the whole idea is to add cost to bringing a car downtown, so fewer people will do it. The proposition is that the harm this does to suburbanites will be offset by making the city more livable for it's residents, and maybe by doing so encourage suburbanites to move inward at the margin.

That's because your unit conversion is invalid. It's entirely possible to construct an equation that computes mi/gal from L/km (or from gal/mi for that matter), but the dimmensionalty of the two numbers clearly disagree. Yes, you can introduce scenarios like yours where "any human" would know what the intended meaning of the question is, but mathematically speaking it's incorrect and encouraging a calculator to perform mathematically incorrect operations is a recipie for both disaster and the introduction of student/user misunderstandings.

I would happily pay more tax in favour of better public services. Especially if those worse off than myself paid little or no tax and those better off pair more.
From what I understand the apartments were meant to be "self contained" so in the event of a fire it would be contained long enough for the fire service to respond. It spread from the outside cladding
That's fine, if at the same time you have private businesses and public offices out of the pedestrian zone.
This isn't really about government spending, since the regulations are written by people not affected by the costs of projects.

It's a bit muddled in this case because it's public housing, but those are still far removed levels of the government (national vs. municipal). The local governments are just one of many groups of stakeholders who regularly provide input to the regulatory process.
Another element is that this was social housing in one of the more affluent parts of London. Thus the value of surrounding properties were prioritized, and sprucing up the facade was put ahead of internal maintenance.
Uh, isn't it called laws? We already codify victimhood pretty thoroughly. This would be a voluntary extension of legal protection to a credible third-party. Not government, not corporate. Corporations purchase their credibility and are also relieved of forming their own harassment policies which tend to be reactionary after the first public incident. Imagine if GitHub had this from day one.
My anecdotal NYC experience has been that private cars are useful for leaving the city (upstate, Long island, Jersey shore, etc) and occasional off-peak trips.

The outer parts of the boroughs can also be far from transit, and cars don't seem such an inconvenience to deal with.
For what it's worth, it works on google.

There wasn't market manipulation here on GDAX's part. The people they are compensating are those who got wiped because they were trading on margin (if anyone is not familiar, this adds much more risk). These people already had their portfolios auto-liquidated via the margin call so stopping trading afterwards had no impact. Same with stop loss orders, although there's a different mechanism at play there.

From GDAX's point of view the tradeoff boiled down to whether to invest in PR / brand today or risk a moral hazard problem in the future (users expecting bailouts so they take more risk).
The heat from the trains etc. heats the surrounding clay over a period of years. You can add less heat, or you can remove heat from the surrounding clay, or both.

Removing:

Run ventilation on high during winter and keep temps quite low in the tunnels.

Run ventilation on high on cooler nights.

Install cooling tubes in the surrounding clay and cool it directly. Either from above, or from the tunnel itself, a ground-source heat pump (geothermal heat pump) to pull heat from the clay. These can be powered by the cheapest available power, likely solar on sunny days in the future.

Adding less:

Upgrade motors to highest efficiency available. This could halve the waste heat from the motors.

Regenerative braking: if it is too complex to put the power back on the grid, build large "electric kettles" and dump it into a vat of water with resistance heaters. The water vat could be part of a water main so it would be constantly refreshed, and result in slightly warmer water for water users.

Instead of ice in the cars, cool brakes and motors that exceed 100C with water, by boiling the water. This absorbs terrific amounts of heat per kg water.

Where can you tell Strauss Khan "literally got a blowjob from a hotel maid" in a case that didn't even go to trial because the accuser was found guilty of "repeatedly lying" in several of her statements by no less than a grand jury?

How about CAPTCHA for unknown calls - numbers not in your contact list will be required to answer something only a human is capable of answering before getting through to you.

Or another approach that Google does with Google Voice is to ask the caller to identify before the call goes through. Then the phone rings on your side and you hear the name of the caller before you decide to answer.
The advice you've been given so far is sound. Do the Andrew Ng Coursera course. It will give you a great introduction to key areas of machine learning. Andrew Ng is a terrific educator.

The level is pitched just right - enough maths to understand what's going on and implement it yourself - but not so much that it detracts from the key focus of the course.

The exercises give you a great opportunity to actually implement the algorithms covered and really aid understanding.
True, true. I live in Chelsea. I'm not surprised that people in outer Brooklyn drive in that area. I'm wondering why people drive in lower Manhattan.
I don't mean that we should change the laws, so that the former grey area becomes the new illegal area; but rather that we should have a stricter attitude about the grey area. Sometimes people's attitude about these things is that, they acknowledge they are wrong, but since nothing illegal happened, they won't say or do anything. That's the grey area I'm talking about -- where there is broad acknowledgement that something is fishy, although it is not technically illegal.

This gray area exists because the law needs to operate under the presumption of innocence, defining crimes unambiguously and prosecuting them with due regard for reasonable doubt -- it is deliberately narrow and permissive, because the state is very powerful and if not held to strict limits it becomes very dangerous. However, those of us who wish to have a good social and professional reputation shouldn't expect to maintain it while doing things that are "barely legal"; and those who witness us doing so should not feel that those kinds of things are not to be mentioned or corrected merely because they are not illegal.
There are also people who were hit because they got margin called. The process here seems a bit ridiculous and the compensation completely understandable. If Interactive Brokers gives me a margin call, I have a couple days to cough up the funds. They don't immediately liquidate my account.
So now we've got thunderbolt.
Public transit done right should be intuitive. I've visited Boston once or twice in my life and The T is easy enough to use, despite having never used it before.

I've flown on different airlines, but the process is still the same for arriving at the airport, checking in, boarding the plane, etc. That's because they all use the same "interface". The process is uniform across airlines. It doesn't matter if you fly United or Southwest, either way you know how to fly.

Likewise, transit systems in towns and cities need to do the same. If they focus on user-friendly design and even work with other municipalities to create a standard, they can arrive at a uniform experience no matter which system you are using.

We have this uniform experience with cars: we assume that no matter where we drive, there will always be a place to park. This is something that has become so ingrained, that the thought of removing these parking spaces is repulsive. But that's the uniform experience I'm talking about. You just assumed that parking will be available, without doing any research to actually prove it. See how natural we've made the process of driving a car? It will take effort, but we can do the same for public transit. This is a solvable problem!

Maybe you've had bad experience in the past with whatever mass transit system a town used, but there is an opportunity there for improvement. How can you make their system as intuitive as possible? How can you make these systems uniform across different cities?
I pick up the calls because I hate having to clear the "missed call" notification. If they leave a voice mail, my entire day is filled with fury. If it's a human and I'm not doing anything important, I usually say something stupid or make gross/odd background noises for fun. I'm not sure if what you saying about the 3 to 6 second stuff is a real thing or if it would make a difference in the grand scheme of things but if so, it would be nice to have a "Punish Them" button on my incoming call screen that does all of this for me.
Directly, sure, but charging your car generates carbon dioxide, as do the manufacturing processes behind the components. Manufacturing an electric car is in some ways worse for the environment than a traditional car.
> But don't expect a suburban lifestyle in the city center.

Since when is an urban lifestyle one devoid of cars? It's you who should move to a small village, where people used to walk everywhere. Large cities were always busy with horse carriages, cars and other means of private transport.

Ask HN: Does anyone need a cheap way to move data OUT of Amazon S3?
Hi HN,

I've recently come up with a method retrieving data out of S3 indirectly using another AWS service for less than the posted egress rates. It is not an exploit of a security vulnerability or anything remotely similar. Also doesn't rely on compression, nor does it use the AWS Export services like Snowball. Technically this could be applied to any data within AWS, not just S3.

I can do this for less than 2 or 3 cents per GB, potentially less, and reliably. I have benchmarked this technique with some data of my own moving files from S3 to Google Cloud Storage.

Does anyone have a use to hire me to implement this technique for them, or know anyone who does? It would be a significant savings over the standard egress rates for people needing to transfer many terabytes of data.

Email is in my profile.
