My ex-neighborhood (Magnolia in Seattle) has had Flock Safety install 6 "AI" camera systems, two at each of the three entry/exit point of the neighborhood. Each installation has a camera overseeing entering traffic and one overseeing exiting traffic. The cameras have license-plate recognition and object detection for car color/make/model, pedestrians, bicyclists and even animals. Flock Safety charges $2,000 per year per camera. Magnolia is one of about 10 Seattle-area neighborhoods with Flock Safety cameras installed. The Magnolia residents themselves pay for the cameras and service. They all can log in to a web service and see the footage and ALPR lists, timestamps, etc.

Friends I have who live there are thrilled with the system although the Seattle police seem to have little interest in the system telling the residents that they are only interested in seeing footage that shows suspicious activities or is directly related to a crime.

Why do you say CH isn’t as fast as Snowflake? Because my experience is the opposite.

Also, Snowflake is so painful to use and has a bunch of weird edge cases. It’s also so expensive.
This is actually more complex than that.

Due to optical aberration wavelengths outside of visible range don't get focused the same way as visible light. This means that the energy is spread over larger area.

Also, both UV and IR light is absorbed in a different way. UV tends to be absorbed much faster than visible light so that little of it reaches the retina while for IR opposite is true, the eye is more translucent to IR and only a portion of it is absorbed at retina and a lot of it tends to pass through it.

What it means is that, while a source of visible light is very well focused on the retina and absorbed in very small volume of retina cells, UV and IR are spread over larger area and then large part of it is absorbed somewhere else.

Still it doesn't mean IR or UV beams aren't dangerous. It is just that you can't directly compare beams by their power.

The way I understand it the main danger is that, since people may not see the IR or UV beam very well, there might be no involuntary response to close the eye.

The Model X uses 22.93 kWh/100 km. Electricity is € .31 / KWH. 22.93 * .31 = € 7.1083 / 100 km

The GLC 200d uses 5.2 L/100 km (best efficiency). Diesel is € 1.266/L. 5.2 * 1.266 = € 6.5832 / 100 km

So yea in DE it may be more cost beneficial to drive diesel than electric. If you get a GLC 300 using gasoline it goes up to € 9.798 / 100 km.

By California law, there is no such thing as ownership of a beach. All beach sands are public, by statute. You are asking who the owner is, but there is no owner of the rights of access or exclusivity, by law.

Of course, Khosla should have access to the lands he owns. Under California law, land is something that private citizens can own. A beach is not one of those things.

EDIT: that being said, private property rights do not always or even typically grant you exclusivity. Many jurisdictions have various requirements on what private landowners must allow the public to do on their land. For example, many jurisdictions have freedom to roam provisions, which ensure that the public has access to wilderness, even if privately owned. The United States does not have this in general, but it is certainly within the purview of the states to legislate such things. In many US cities, homeowners own the sidewalk and must maintain it, but allow the public access. This is written in the deed, or mandated by statue.
I'm not planning to buy a house until after I'm married.

Also, houses here tend to all be over $1M, good ones well over $1.5M. The average sold house price last month in Palo Alto was $2.76M with an average ~1900k sqft: https://www.redfin.com/city/14325/CA/Palo-Alto/housing-marke....

Additionally, I'm slightly concerned about a possible real estate bubble + I'm not sure if I plan to live in South Bay for 5+ years (the usual amount of time needed to keep your house for it to be worth it financially).

It's not that I can't afford a house, I can; I'd just rather have my money in an index fund and rent instead right now.
Who says progress can't be sad?

The consolidation you're talking about was a massive disruption, which brought a lot of change to families and societies. Most kinds of change are painful even when they lead to greater efficiency.

While the transformation of agriculture has led to great prosperity, prosperity also brings hierarchy; i.e. more unequal social forms.

Much of the US has transitioned from a relatively agrarian and egalitarian society to one that is much richer, but also less equal and more divided, in the last 150 years.

There are clear tradeoffs in that transition, which some people might call the march of progress. Ways of life die off, and those who knew them in childhood often regret their passage, regardless of whether the world's wheat production increases.
This is quite a claim, but it's too vague for me to research independently. Where would I even start in exploring the "enormous body of law" that "incentivizes a top-down corporate business structure?" I am not asking rhetorically -- this is news to me and I'd like to know the details.

Of course, co-ops aren't common in the US, but they do exist (like REI) so I'm just curious about the details of this criticism of the legal landscape in the US but without further information am unable to research the claim.
Ok, what if lawyers were biased and "simply" declined to represent one class of people because I dunno, they are "debtors" and don't deserve representation against an authoshop which ripped them off.
100% this. Hopefully by the end of the decade data collection will default to opt-in rather than opt-out.
Perfect, they should bring back serfdom and have the filthy rurals work and keep it quiet. Might allow them to go to church every Sunday tho.
You're right I think some are overdone. One example is the consultants taking a plane 2x a week (leave early monday, come back thursday eve, often with unconstrained distances). Maybe a bunch of those could be cut, though in that case I think a lot of these business models offer a "premium" service. If you're paying $1M/quarter for a McKinsey contract or for an I-banker or a big 4 accountant you definitely want to see that person physically. Though keep in mind McKinsey is also probably less price sensitive than the average flyer.

Still even with that, I'd like to better understand the economics. If only 12% of trips are business vs pleasure, killing all business trips won't move the needle in the long run. There's some question of how long business trips are, you can be 12% of trips but if they're longer it's worse.

My overall point is that there are a lot of factors in how people chose to travel. It's far from clear that increasing the already quite high price is what's going to deter people unless you tax it massively. In which case we'll effectively return to a situation like the pre-deregulation days where only the rich flew, which may be fine, but should be directly considered.

How many secured part-time jobs?

Land ownership is a social construct. It's not like ownership over something you make with your hands or your mind, and in the US, all of the land is stolen property anyways so there's no rational claim to any of it.

So land ownership is a right afforded by society to society, like any other kind of legal framework, and part of that is limitations. In earlier parts of human history, if you tried to cut off a population's access to a valuable resource like water by claiming land ownership, they'd just come with sharp implements, impale you on them, and take the land back from you. In modern times, we need to accomplish the same end, but with hopefully no bloodshed.

That's neat, im just not much of a .NET person myself and I guess that using a language/framework that is enjoyable is more valuable to me than the portability aspect. I came into React Native for those portability reasons, and it wasn't enough to keep me excited about it. I don't see how Xamarin and .NET, which im even less into, would be different.

Also I'm not sure that Xamarain or QT are really very relevant, HNSVBubble or otherwise.

I think reducing CO2 emissions from a personal level is the wrong way to go about it. It needs to be addressed from a more higher level, because the majority of CO2 emissions cannot be attributed to a single person.

Take for example shipping, which uses 4.5% of global co2 emissions, yet most people haven't stepped on a ship in their lifetime, and never will!

But this is where I am confused, if you read a bunch of the Google Map reviews on this beach you can just walk to it from the road. What was blocked?

Water rights aren't your average yard. If water rights aren't protected, the rich could buy up the entire coastline and you'd have no where to access the beach.
He doesn't own the beach, and an easement to access public land is a normal, non-controversial thing.
> Who the owner is should not cloud the argument.

Fair point, but...

> On the other hand if his purchase did not include exclusivity to the beach then by all means go there and piss around.

This, by law, does not exist in any form in California (unless the beach is on a lake rather than the ocean).

This is simply a case of someone flaunting the law.
Well, I tried to write about what it might take to create a viable WordPress alternative that'd appeal to the non technical user.

Yes. Clickhouse is a column-oriented relational database among many others like MemSQL, Vertica, Redshift, BigQuery, Snowflake, Greenplum, etc. They're all focused on analytical queries over very large datasets using SQL.

An aggregation with several `group by` statements is no challenge and all of these databases also support approximate counting via HyperLogLog for faster results.

Clickhouse has some unique features where each table can have a separate 'engine' including some that automatically apply aggregations. Start with a normal table though since it'll be plenty fast enough for most use cases.

Never underestimate people's willingness to grab money now even when the rational long term strategy would ultimately pay more.
This has nothing to do with him being rich. This has everything to do with the fact that he is an asshole. He has no property rights to the beach but is spending his money trying to change that.

He has no right to do what he is doing but the only reason we are talking about it at all is because he is rich.
No, it will just be all server side and you won't have any choice.
Mmm. Good question.

Personally, I don't see the rest of the world as willing to indulge in that type of regulation havening. Besides which, where else are you going to find the combination of hypermodern physical infrastructure, relatively stable political/judicial systems, and the fiscal infrastructure to support these types of businesses all bundled together?

It seems to end up being a puck-two sort of thing otherwise, and if they did move out, they'd likely have to instantly write off the American market, as such a drastic measure would not go unnoticed. It starts to reek of nationalistic pride as the insurance policy, but history didn't build itself up without such a thing in the first place; so I see it as foolish to discount the mechanism moving forward.

One can only hope the cost in blood to maintain such security won't have to be repeated however.
For a really long time I've wanted to start an organization for this explicit purpose: raising awareness of disinformation and exploitative online scams and how to identify and avoid them, and teaching people positive ways to interact online and make their online interactions more constructive.

Sometimes, especially when dealing with interactions between chips, even sub-cycle behavior needs to be emulated for correctness. I suspect for basic emulation though, rigorous cycle accuracy is not really necessary for most software...
A farmer in my village in Switzerland imported a 1980's Ford tractor from Texas. He had to repair the front axle, which had been cut. He told me the axle was cut to render the tractor unusable after it was traded in for some kind of emissions credit. Anyone hear of such a system?
What? California beaches have been public property since 1976. He bought the house knowing he doesn't own the beach, and that the public has a right to that beach.

No one is allowed to own a beach in California. This isn't about mob rule, this is about a choice Californians made many years ago that says beaches are public.

The beach is not his.
Why shouldn't they? I think it's ridiculous to be able to review something which you have not experienced and I don't see a good reason why they should be allowed. The lockout should be until at least one person (ideally more) have experienced the fully released product.
Just wondering if there was a way to get more data for non-US locations. For example, according to my knowledge, most of Canada's "senior" position salaries (in CAD) are not even near the "entry-level" salaries (is USD). If you convert the CAD salary to USD then it becomes even more pathetic. Canada has "free" healthcare but the taxes are higher than California/Seattle. Granted, you don't have to spend 2-3M for houses (only California), but the housing markets around Toronto, Vancouver, Ottawa are also anything but "affordable" (around 700k-1.5M mark). I wonder why there is such a huge pay disparity between two neighbor countries with sort of similar "standards" of living. Just house prices and "free medical" (which is covered by your job anyways) cannot justify the 5-7 times salary difference. Wondering if anyone else had other opinions?
Quite a lot of them. The publishers are quite upset at the price collapse of used books as people go grab those up.

First, I'm assuming there is actually a reason to limit the public's wandering through military bases. If that's the case, ISTM that safety only requires the public stay out of probably-already-fenced actually-dangerous areas. Keeping the public out of all lands must be for some less tangible reason like "national security".

People can walk on unfenced land whether or not they have an AR app. If it's important that they not walk there, put up some signs or increase patrols or whatever. Those are local solutions that aren't easily aggregated by a single app developer seeking all locations with "national security" connections.

Airspace may be restricted for any number of reasons, especially safety. Also, we can't build fences in the air. So, airspace restriction for reasons of "national security" can hide among all the other airspace restrictions. On the ground, that isn't the case.
But, it was not taken. Khosla came to acquire the property well after the 1970s, which is when California law allowed the public to use all beaches.
Because the language is attempting to have a standardized formatter. I'm all for it, personally.
The parking and road existed as public access before Vinod bought the house. The argument is where something that was public before can be made private without prior approval.

It depends. I used to self-host a VPN on DigitalOcean's VPS and didn’t experience any issues when routing all my traffic through it. But I suspected being logged in to my Google account as well as presenting cookies created for a residential IP address helped with that.
> it seems like a very reasonable expectation that the state would maintain it

As a matter of principle I'm inclined to agree. However many (possibly most?) US cities require the property owner to maintain the sidewalk fronting their property; this situation might be similar.
For me as long as a core group appears to be active I’m fine with a communities survivability. Julia’s data-science and plotting have continued to improve in terms of documentation and feature parity, both are critical in an immature ecosystem as they indicate an active core group of developers. Also many libraries appear to be driven by academics creating cutting edge libraries or developing "workhorse" libraries. One good example is Steven G Johnson’s involvement in Julia [1,2], since he created the FFTW library and NLOpt I’d put him in the category of ‘prolific data science contributor’. Or are take the Julia GaussianProcesses.jl [3] library which has a surprisingly thorough implementation along with academic research (and its citable!) for speeding up GP fitting. Pretty cool! Plus it’s pretty performant to say use Otim.jl to optimize the "hyper parameters" for a set of GP’s. That enables a lot more iterations of data exploration.

Essentially the base ecosystem of a language is driven by a core group of contributors and the derivation an ability of that group matters more than most other factors. When doing scientific and or data science I personally care more about the core quality and what the platform enables. Lately I’ve considered learning R as it has a lot of well done says which simply aren’t available in Python, and aren’t ready yet in Julia. Last time I tried to calculate a confidence interval in Python for an obscure probability function I ended up wanting to pull out my air in frustration. There’s libraries that kind of handle it in Python but they are (we’re?) nigh impossible to modify or re-use for a generalized case. Much less getting a proper covariance matrix with enough documentation to know what to do with it. I used R examples to figure out the correct maths. R’s NSE seems appealing in allowing generalized re-use. I’ve had similar ability to re-use library features in Julia for solving problems outside that libraries initial scope.
