Q: Did the videos reveal any surprises?

A: Cats are seen as relatively lazy, especially compared to dogs. But we saw that when they were outside, they became superalert. They scanned their surroundings, sometimes for a half-hour or more on end. And even though cats are highly territorial, they didn’t always fight with other cats they encountered. Often, they just sat a couple of meters away from each other for up to a half an hour. They may have been sizing each other up. Sometimes they would engage in a greeting, briefly touching noses.

When they were in their homes, the cats spent a lot of time following their humans around. They liked to be in the same room. A lot of my students were surprised at how attached cats were to people.
> What you mean is a 50% alarm/trigger rate.

No I don't. It's just that the true positive rate is close enough to zero that both false positive and alarm rate are roughly the same number.

Nevertheless you're still not understanding "false positive" correctly. If you correctly pick 5 out of 100 true positives without any flaws, and also have a 54% false positive rate, you're grabbing 51 false positives, and >90% of your picks were incorrect.

And I'm pretty sure the true positive rate is well under 5% to start with, which just makes it worse.

"In Germany, the false positive rate was 54 percent, meaning that every other person who went through the scanner had to undergo at least a limited pat-down that found nothing."
This is wrong. Even your quote shows this. A false positive rate is how often it triggers when the true result is false.

> A false positive error, or in short a false positive, commonly called a "false alarm", is a result that indicates a given condition exists, when it does not.

So 50% false positive rate means 50% of people who should not be flagged are flagged.

I like this way of thinking about things. Another one I heard recently is that whatever you do you'll regret it. Get married, you'll regret it, don't get married, the same, etc. So regret is a constant, which is comforting in its way
You didn't answer the question: what is so horrible about trying to help oneself by tempering one's emotions and seeking happiness within?
Would you rather we don't have these numbers help us with decision making? Do you have a better system in mind? Should we just never discuss or think about risk/reward trade-offs as soon as it involves a single life at risk?

I also don't get where the Wikipedia snark is coming from. I know that Wikipedia pages are not perfect but It's still a pretty good reference for a lot of things. I often trust Wikipedia articles for any given subject as long as it is well-sourced and not political just like this one.
That is patently false, unless you plan on starting from a clean slate on the new environment. Any one who proposed such a solution as a business continuity practice to me would be immediately fired.

Containers solve the easy problem, which is how to make sure the dev environment matches the production environment. That is it.

Replicating TBs worth of data and making sure the replica is relatively up to date is the hard part. So is fail over and fail back. Basically everything but running the code/service/app, which is the part containers solve.
i understand the loan part, i don't understand why they have an interest rate to begin with. aren't these loans guaranteed by the government anyway?
Sure. But until we resolve the accountability, we shouldn't increase the power of law enforcement. The more unaccountable power they have, the more it will be abused, and the graver the abuses.
> wireless carriers may break their monopoly suddenly.

This sounds like Comcast's argument, which is that there is already sufficient competition due to wireless carriers. The fact is, a fixed line will always be faster.

Are Google employees not free to do as they please now? If anything, they're being funded to go off and start their own companies. They're not enslaved by high salaries, lol. Quite the opposite.
Absolutely not. Kids age < 4 get these all the time. When they cry or feel bad, you don't know if you want to go to doctor all the time. For poor people this is even more difficult decision. Ear infections when treated early can be much less painful or even dangerous. This kind of apps is definitely useful.

How are you going to stop tracking?

Whenever you interact with a business, online or offline, you're supplying information that can be tracked.
In my case native clients would use anywhere from 1/10th - 1/100th the resources.

And everyday the app will freeze for 5-10 seconds at a time on a 2018 MacBook Pro.

So Slack really only does 1 thing which is a chat app and if they can't do that properly then you have to wonder.
I think there are two issues operating here. The first issue is that there is absolutely a genuine business case where as long as your COGS is close to 0 then you literally can grow into profitability. That very clearly applies to Slack and other internet companies where you build the application and you're basically incurring only fixed costs.

The second issue is that we have a number of companies that aren't that style of tech company that are wrongly valued like that. Companies like Uber, Tesla WeWork etc. All attempt to mask their traditional business with tech. I think we can make a pretty strong case that what we're seeing there is a bubble that will burst.

It's always more profitable to rent out means of production than to do any actual work. (capital gains cannot be explained purely as the reward for the work of managing said capital, this was was pointed out by Adam Smith). Fairer distribution of ownership means fairer distribution of income.

Those loans don’t need to be repaid, they’re a graduate tax - 9% above £25k for 30 years.

Opinion piece
Not just that, but educational attainment in general, demographic changes, economic changes etc.

We've shifted from a population that does not die old, starts working early, stops education early, and does most of its work in the primary/secondary (agri/manufacturing) economy where its most productive when young.

To automating those jobs and shifting to a world where we grow old, stay in school longer, have high returns on education in our tertiary service-based economic productivity levels, which gets us to be most productive in middle age, which also coincides with most of our investments in personal housing equity, retirement funds and paying down debt.

Not a huge surprise that if you take a few age cohorts, that a young one will drop in wealth, while an older one will grow in wealth. Our society lives and works longer, and prepares longer for this work in school, which has more individual-benefits and thus higher individual educational debts at a young age.

As such, I wouldn't be surprised if the wealth-hump didn't just move over a few years. Losing 1/3rd wealth within a certain age cohort (18-35) would be no surprise if half the wealth of 18-35 year olds was generated at 32-35, and this shifted to 35-38. I'd be most interested in seeing a graphical wealth distribution by age, for different generations, then you'd know if this was a story of decline, or a story of shifting the 'prime productivity' age by a few years.

That having been said, my post was mostly on a 100-year historic scale. Things haven't changed quite as much since 1996, but I think it's still mostly linked to the same forces.
Not necessarily. The reasons people drop out are family emergency, cost, personal emergency, and not being able to deal with the workload. Most of these reasons don't necessarily cluster in the first 6 months.

No, that would conflate socioeconomic factors with race and be unconstitutional, for good reasons.

GGP was talking about data collected involuntarily, and I was responding to that. Google (or any other company) can't have your entire email history, your travel history, and recordings of your voice without your voluntary participation in one of their services or services of a "partner". Those are way beyond drive-by collection.
It sounds pretty clear to me he knows how awful it is. Why would admitting he's still a karma whore mean he thinks it's not awful? A drug addict can know being a drug addict is awful while still admitting to being a drug addict.
At least for subjects like math or programming, I think the right way might be self-study (going through a textbook and solving all exercises) plus an hour of one-on-one time with a teacher every couple days to check progress and resolve questions.

I don't think librarian salary is enough to pay for effectively trailing spouse.

Single income has very real consequences for both spouses (the one giving up work experience and the one being sole provider) and very real risks. It has consequences on familly dynamics and ressentments, especially when bad times hit and money are not to buy what both wants.

in theory this works but there's a flaw: hours worked. How many hours worked isn't the same as much value someone has added to the company or how much work they've actually done.

In addition sometimes value added to the company isn't realized until months later. And sometimes hard work doesn't add any value to the company.

What chance of government-mediated genocide does it take before accepting an extra ~8000 murders/year makes sense? Not very high, in my opinion. (And that assumes that half of all gun homicides go away, and aren't replaced by other weapons)

One genocidal government killing 0.5% of the US population every 250 years is 8000 deaths per year if my math is correct. With how everyone seems to be complaining of the US's recent descent towards fascism, I find it rather disingenuous to argue that a genocidal government is less likely than that.

From what I've seen if you build the infrastructure it doesn't change residents attitude to increased density. Actually makes them more opposed as they now have very good public services compared to elsewhere and they don't want to lose it.

Unless your website is under targeted attack just putting "2+3" on a image will block 99.9% of all bots. You hardly even have to distort the image or randomize the math but doing so could help against script kiddies. Only drawback vs reCAPTCHA is you have to show the captcha all the time instead of automatically suspecting bots.

If you are under targeted attack by someone more dedicated, captcha is not going to be the only defense in your book.
This is bit overblown article. Certainly bad zoning laws can help inflate prices and there are several other factors like investors using real-estate for investment. However the major cause of real-estate price increase over long term is plain and simple: heavy urbanization of entire world. If you look at graph of population moving to urban centers over centuries it looks like literally almost vertical line in recent decades [1]. I'd heard that 90% of Earth's population is concentrated around just 40 urban centers! The real-estate in rural area has remained same or took nose dive while in urban areas it keeps going up.

Interesting question is how fat this trend will keep going? My guess is that this is black-hole effect, a larger city attracts even larger population towards it. Japan has recently became outlier because of economic issue as well as population decline.

not sure why you are being down voted, its true.

assume home prices go up 5% and the stock market goes up 7%.

If I want to buy a house for 100k and put 20k as a down-payment and live in the spot for 5 years, I can make 8051$ off the stock market (invest 20k) but my home would have appreciated 27k$.

sure there are some other factors, and maybe my numbers are not right, but I think it gets at what you were saying, an advantage of buying a home is you can make a leveraged investment.
>I'm assuming their business side is as complicated as their software

That assumption doesn't hold. Google's business model isn't that complicated. Industry experts and competitors understand perfectly well how Google makes money. Any investigation will focus on a handful areas that are well known and often discussed.

And when it comes to understanding who at Google has done what, why and when, there's prisoner's dilemma to the rescue. If investigators question a couple of managers under penalties of perjury, they will put their own personal interests (i.e staying out of prison) over Google's interests and just tell the truth or at least say something that isn't provably false.
Most of the middle class and up in the UK have a significant chunk of their wealth tied up in property (their own homes, then investment property), so not really.

There is an elephant in the room, and the elephant is called dual licensing. In my opinion, this is a more severe abuse of open source than what Amazon does.

When RMS introduced GPL the idea was to make everyone share their code, and make the world a happy place full of free Software. Dual licensing abuses this sincere intent to induce fear in commercial users and make them pay.

So using a dual-licensing scheme prevents people from considering authors of SSPL the new leaders of the open-source community.
Packt seem to be a quota publisher. They're more focussed on getting a steady stream of titles out of the door than making those titles definitive, and they tend to spam anyone who looks even slightly competent. I know a number of people who had offers from them, and they're invariably low-ball compared to other publishers.

The top tier publishers pay an advance - which you probably won't ever make back, so you may as well consider it final payment for the book. O'Reilly like to pay nothing up front, so all you ever see are royalties. This can work well for a popular and timely topic. Niche titles won't pay much, although they can still be a good thing to have on a resume.

The really big money used to be in the mainstream - how to use Windows, how to set up an iPhone - but that's less of a thing now that a lot of people Google for help.

Sales figures for hardcore developer titles can be very low. Five figures for a developer title is a solid success. Six figures would be a wildly unexpected best seller, and seven figures a complete unicorn. Four figures are more typical, and high three figures can happen.

The catch with royalties is whether they're a percentage of the cover price or the publisher income. Publisher income can be 50% or less of the cover price, so that's a thing to consider when working out if a book project is worth the time.

With self-publishing, you keep a much higher proportion of the earnings. Anyone who is thinking about this should work some numbers through a spreadsheet. You'll find you can make the same money a publisher would pay with far fewer sales, and if you can get four or five figure sales - unlikely and very difficult, but not impossible - it's a nice alternative income stream.

If you already have any kind of following, it's a no-brainer. If you don't, it's a huge marketing effort, but you still get to have final say on the timing of updates and revisions, which can keep a title earning longer than a publisher would keep it alive.
"Old Town Road" is a useful modern reference for what we could have in a world without Copyright. That sample behind everything is from 34 Ghosts IV, one of the tracks in Nine Inch Nails' Ghosts I-IV album.

Strictly just pasting it into a song and selling it wasn't legal (presumably after this went viral somebody paid Trent Reznor a bunch of money and put his name in the metadata to avoid nasty legal consequences) but everything up until selling it was legal, all the raw PCM data you'd want to take the samples apart without painfully cutting it out of the entire Ghosts recording was uploaded with the Ghosts I-IV album as CC-NC-BY. This is how our culture was _supposed_ to work if we weren't still trying to find ways to put more money in The Man's pocket.
Please don’t go ahead if it is for Packt. We had a horrible experience with them.

After a bunch of hunt we moved to what is called a first tier publisher. And the difference is so massive. We are now restructuring and rewriting all chapters. Our reviewers think it can be a landmark book. None of it could have happened with Packt.

I come from a startup world, and was partially able to stomach Packt at the start. But my co-authors have worked at Microsoft Research and Google AI. They just hated dealing with them. And in the end all of us decided we would rather self publish than go with them.

But it don't have to take a depression to create sinking house prices. In Sweden we had shrinking house prices between 1931 to 1981, with only three years (right after the war) when prices increased. The same period is the most economically successful period we ever had.

Why? Because politicians built a shitton of houses (and tore down a lot of crappy housing too). Nowadays people here too think prices always go up, not realizing it is a political choice. It may very well be the right choice, but so many doesn't even understand it is a choice in the first place.
