I'd be interested in hearing someone with knowledge talk about how these models get used in practice. From an engineering perspective it seems like actually applying them would be very hard.

For example, how good are parameter estimates and how do we know if they are good? If I was designing a controller for a plane, I can spend a lot of time getting good parameters for the plane model and design a controller that looks good in simulation. However, when I take the plane out, it might not be stable (or doesn't meet some other metric I designed for) because the parameters changed due to a variety of physical factors and/or the model is a model and thus doesn't account for anything. So I go back and forth tweaking the controller design until I get something that works. That process isn't really feasible when it comes to economies, though.
I think he's referring to efforts like this one:

Never heard of McMansion Hell before, but went back and checked it out on Google Cache and it just seems mean spirited. Why should anyone care what sort of house people choose to build, buy or live in? Reminds me of the people that couldn't handle an old lady's earnest Olive Garden review a few years back.

I lost mine about six months ago and I haven't replaced it. First couple months I noticed I got VERY irritable when I got a momentary flash of boredom, especially waiting in line in stores, etc. Figured that might've been a budding mental issue, and decided to work on my patience and expectation-setting as a result.

This has been part of a larger life exercise in practicing general moment-to-moment mindfullness, and I think I'm going to keep this up for a while and see how long I can go without a smartphone before people start asking me questions at work. So far, so good.

It's like I've withdrawn from a drug and some of my attention is back under my control, where my mind can better keep its peace. I guess I didn't exercise proper discipline when I had the phone.

How does Zeroconf compare with UPnP?
You posted exactly what I was thinking. I recently gave my parents my iPad Air 4th gen and orienting them to it was an eye-opening experience. They are retired but they both worked as programmers (think COBOL-era). I've owned an iPad since launch day and so many features that feel instinctive -- double-tap home button to bring up apps, slide-down-from-top to see notifications -- are decidedly not. And that's before you get to the confusion of what's the difference between logging into email via the browser, versus a specialized app.

And then there's me. I got myself an iPad Pro, one of the 9.7 inch models that Apple didn't see fit to put 3D-touch on. It took me a long time to realize that the reason I couldn't delete items from the core TV app was because the delete functionality, which used to work on a long touch, was deprecated for 3D-touch. The amount of no-shits given by Apple designers toward long-time users with year-old devices still amazes me. Making iOS more like a computer is appealing to me, but I feel bad for the non-professionals who are likely to be super confused.

More nitpicking:

> You can prove that by writing a simulator for a Turing machine in your language. Since Turing proved his machine can compute any computable function, by induction, that means your language can too.

That's not by induction, that's by composition or something.

> We almost have the third too. You can create and concatenate strings of arbitrary size, so you can store unbounded memory.

That's not true! Eventually you'll run out of memory & disk space. Turing machine tapes are infinite, you can't fit one in this puny universe.

EDIT:

> Syntactic sugar has a bad rap among the PL intelligentsia.

Um, what? I presume the author isn't aware of the large PLT group at Northeastern that continuously writes papers about macros, i.e. user-defined syntactic sugar, and develops Racket, a language built almost entirely out of syntactic sugar. Or maybe they're defining "syntactic sugar" to not include macros: if so, they should be more clear about that.

Also, I'm doing a PhD focusing on syntactic sugar, so I probably have authority to say: syntactic sugar has a very good rap among the PL intelligentsia. Languages with a needlessly complicated semantics have a bad rap, but that's different from having a large grammar. PL researchers are a lot more concerned about semantics than syntax.
Well, hypertext is "hyper" because it is more than just text - images, animations, as well as links, are the most basic building blocks of the Web. It's not like we've invented animated GIFs in the current decade - the pages in the 90s were as full of unnecessary "things" as they are now; if there's a difference it's in what things the tech lets you shove into your HTML.

Also, you can get pretty close to the experience from the 90s if you disable loading images in your browser and/or use uMatrix or something similar. You'd be amazed how much faster it makes the web, at least on the pages which support plain HTML (instead of rendering everything in JS). You will be missing most of the visual bells and whistles, but it was also like that back in the day: not only did graphic elements (and don't even mention Java applets) take forever to load, they frequently stopped loading altogether, leaving you with a cute Netscape icon in a place where the image should be.

I guess what I want to say is that there was never a time when a majority of "webmasters" designed their pages for simplicity. People creating the web pages were testing the limits of the medium since its inception, and what we have now is a consequence of the limits being removed by better technology.

In other words, people who create websites were always shooting themselves and their users in the foot, back then with some ASG, then later with increasingly potent guns and now they're shooting with 10 meters long cannon. And it's not going to get any better, unfortunately, because most people want their eye candy - just as much now as back in the nineties.
> The new lock screen makes a lot of sense on the newer iPhones.

Sure, but have you used it on an older phone?

Just recently I was trying to explain how to unlock an iPhone 6 hand-me-down to a relative by pressing on the Home button now that slide to unlock is gone. They initiated Siri 90% of the time instead of unlocking the phone. Is that good UX?
I did some hands-on research, and I now agree that you are correct. The behavior is absolutely acting like a resumption of the TCP session, not extra connectivity magic within SSHD.

Thanks for the persistence!

That said, though, there is something which closes idle, established, TCP connections, though it's not the kernel, it's iptables which does it. The timeout is something along the lines of 5 days by default, however. That's what I get for working from memory.
I don't see what the problem is. The IPv6 address space is so large it doesn't matter at all.

Now it's time for me to apply for the third time, and probably not get even an interview, just like the first two times.

Maybe I should stop applying with just ideas, and apply for the company I have actually been running, even though it's not a "tech" company per se.

Can someone with a background in HR fill me in on what the term "investigation" means?

An interesting article ... but not sure it's that accurate to compare economics to physics ... the closest situation comes to mind would be the phenomenon of turbulence ... which still is more manageable than economics since the controlling principles are known and controlled experiments can be performed ... on the other hand, an economic system involves many many agents of different scales, most of time seemingly rational but certainly emotional, interacting nonlinearly at all scales, without much chance of controlled experiments ...
Where I work, we'd be totally happy to ask interviewees how to reverse a binary search tree. As soon as an actual developer creates a pull request that does as such. Which hasn't happened yet. So we don't ask about things like that. And everyone seems happier.
You can do it in Python as you have, but it becomes second nature with Haskell (I can't speak to Elm directly). You might not even realize you're doing it.

Add 5 to each num in a list (using a pretend function called `add` in both languages to be fair):

map(functools.partial(add, 5), nums)

map (add 5) nums

Add 5 to each in a list of list of numbers:

map(functools.partial(map, functools.partial(add, 5)), nums)

map (map (add 5)) nums

For the second time today, I am going to suggest seeking the council of a qualified legal professional. Up above, you admitted you just copied some site's terms of service. Now, I am seeing that you haven't actually checked the various services for their list of rules.

You're quite likely to end up in court, should you actually get noticed. Seriously, hire a lawyer. I am not kidding. These sites kinda value their data and have a variety of limits for using the data - even if it is public facing.
Thanks, we tried to keep it simple and streamlined. If you know of any features or common patterns that would be helpful, let us know.
Those bards trained to do that, though, right? You couldn't pull a random Greek in off the agora and have him memorize an epic poem at will.
Good points, just wanted to point out that, according to their documentation[1], Apple ARKit doesn't do SLAM, but Visual Inertial Odometry, which is one of the (important) components of a SLAM system, whereas Tango does the full SLAM pipeline with loop closure and relocalisation, and should therefore enable more, larger scale applications and allow for persistence between device/app reboots etc.

> Her only hope to get through the next five years without having her life substantially wrecked by a totally unnecessary lawsuit (which she will likely lose if it goes to court) is to comply with the C&D and hope that Zillow calls off the dogs.

If she would likely lose in court, then Zillow has a legitimate case against her and is doing her a favor by sending a cease and desist instead of going straight to court and taking her money. I don't see why you would feel sorry for someone in that situation.

I feel sorry for her, but that's because I don't think she would lose in court.

The 21st Century Garage Startup
I had a YC company that wanted me to do a trial week. They wanted me to quit my job when I said I couldn't take off a week of vacation.

When I said no, they wanted me to come out Friday through Monday and since the whole company works on the weekend, they would get 4 days to work with me.

At that point I said I wasn't interested.
I thought I was the only bothered by that blog (the 99pi episode was based on it).

I agree with practically all of its conclusions (ugly, oversized, out of place, generic, etc.), but the entire thing was a bunch of worthless value judgements: this is bad, that is bad. Not: this is bad because of function, but literally "this should never happen" -- no explanation.

Real example from way back machine, from the blog's most recent post there:

A transom should never overwhelm the door or window it’s sitting above.
Here’s an example of how to transom:
And how to…not:

... that's it. No explanation, just "I'm right, they're wrong." It's just lousy, valueless criticism. Nobody would take this lazy opinion drivel from any other kind of critic.

(Separate: Do I think zillow was right here? Of course not).
I agree. Aside from the egregiously asshole move of auto-playing video (sometimes related, sometimes not), I can typically read an article much faster than an anchor can narrate it.
I like both kinds of data structures- maps and lists.

Builders and purchasers don't care about architecturally sophisticated dwellings because they are too busy "keeping up with the Joneses".

I disagree with your assessment of elitism. If every "critique" is "elitism" then I really don't know how to respond.
Yours seems like a flippant response, but I don't think that it is. We have to be wary of confirmation bias here on HN. Would someone even think to publish a study where no effect was found? And then would someone post that link to HN? And then would it get upvoted? It's important to remember that we are not seeing a uniform sample of news stories here. We are seeing a highly biased selection, and it's important to appropriately discount things appropriately.
Funny timing, I almost got hit yesterday (at a speed that could have been fatal) by a driver who most likely was either checking notifications or actively texting, while I was biking right on the UC campus. Immediately jerked my handlebar to the right and dumped myself into the grass and escaped with a huge gash above my left eye. Our self-driving overlords can't take over soon enough.
> Isn't that just another economic theory?

Yes, in the same way we could formulate a medical theory that says "we don't know enough about disease to know whether our treatments are effective, so we aren't going to create a standard diagnostic manual". Prior to the last couple centuries, that would probably have been an improvement.

No, in the sense that, compared to most economic theories, you can't really use this theory to justify a particular group being given access to government power.
I do the same, though I wonder if a part of my brain is still itching to check if I have any notifications.

> Their retail/ecommerce revenue alone is around $100B. Overall, they are going to top $150B this year. Without AWS which is their primary profit machine right now, they are still at $135B+ in revenue. Don't you think if they wanted to, they'd be able to eek out a few billion in profit from that remaining $100B+ in revenue if they decided to go that way? That would get their PE below 100.

Amazon can't actually compete with us on price without selling below their costs. That is the reason we are still alive despite Amazon moving into our market. They can't raise prices _at all_.

Their ability to do so _entirely depends_ on them becoming more efficient. I suspect they can't become substantially more efficient on the retail side than they already are.
It will be cool to see advancement in this area and any potential cross-over with tech research for Martian and space agriculture.

Pro-ISIS group defaced US Government websites in 3 states
My wife and I recently spent a few nights at an Airbnb in the mountains where we couldn't get cell reception and the wifi had a crappy satellite Internet connection we'd been asked to avoid using as much as possible. Also none of our digital crap was there, just a few physical books we brought and some card games the hosts provided.

It felt great. It's had me thinking more and more or the digital things and the hyper-available entertainment and information (and, maybe importantly, hyper-available choice of which to indulge in, at a moment's notice) as kind of junk-food like.

Yeah it's cool to be able to watch all this crap from my childhood, and a thousand great tv shows or movies, or hundreds of the best video games yet made, or browse endlessly for new music tailored to my tastes, or whatever, totally on demand—but maybe that kind of thing's just not healthy to have around.
But you won't know the number. You'd need to go to as library first, log into whatever service you keep your contacts on (I run my own radicalie carddav, but most people use Google or Apple's services) and find their number.

I use to have most of my friend's phone numbers memorized by the shape they made on the keypad. Today we stay in contact with a lot more people, or at least I do, and it helps to no need to memorize numbers.
> A book (assuming it's a real book and not something slapdash) is a major piece of work.

It is, I hope. But if you're prefer I post these without "Show HN", I'm happy to. I thought it was worth doing it to make it more obvious that I was self-posting, but I can not do that if that's what others would prefer.
I guess it depends on whether you want to agree to that stupid system. When I interview now, I rarely ever prepare, and I'm completely honest with the extent of how much I remember and don't with the interviewers. If, on learning this, they think of it as a deal breaker, I think its a good thing for both of us to not be working together. However, if they don't judge me, but are willing to provide that information and work with me on the solution, I am fine with it.

I had a really bad experience with this recently, where I had a final interview which went really well in 3 out of 4 interviews. In one of them the interviewer was expecting a very specific solution, and I believe that I said something like, sorry I don't exactly remember how tries work, and I believe that is what resulted in no offer.

At first I was disappointed greatly, since it seemed like a great opportunity, and I had a great interview and experience with the other 3. But in hindsight, I realized I would really not enjoy working with this person every day.
> It's punching down

I generally reject the premise of punching up versus down; but McMansion Hell is emphatically not punching down. Anyone who can afford a $1 million 5000+ square foot house deserves very little sympathy for their bad taste.
I kind of like the McMansion property of looking like the house was built piecewise. It's a little endearing, I find. Actually, Castle Neuschwanstein was built that way - it was all built in one go with modern techniques but has a lot of different submasses. But I have to say the execution is often lacking. Proportions have never been the strong suit of evolved buildings, but there's an obsession with traditional markers of wealth (roman columns, etc) that don't really work when you don't have the money to build the other things equally large.
Strange that Apache Flink and Google Dataflow don't figure in the Stream Processing list

In many ways, git is a content addressable storage with a couple of metadata, remote synchronization and merging features mixed in. bup uses git's internals to great effect for a backup system, and borg drops git compatiblity and elegant multi-client support, but goes farther by providing other backup functionality such as efficient pruning and built in encryption.

I think there's a subtle difference between "monitoring for notifications" and actual notifications. Your phone might be on do-not-disturb mode, but that doesn't mean your brain isn't distracted wondering whether someone replied to your last message or returned your call from yesterday. Taking it out of your pocket and leaving it in another room or your car or wherever lessens the compulsion to frequently pull it out and check.
Account system reduces the amount of people bypassing the 1 concurrent export per person limit (although I could do more on this front). I used this site so I can get a job coding since I'm an English Lit major who doesn't want to spend more money on school, which, thankfully, has recently paid off as I'm starting a new position next month. Also, $10 a month isn't a lot to pay for a fun project that will (maybe) help a bunch of people, but I can understand the suspicion.
It's easier to throttle people if you have to use an account to access the information.
