Many places which are unsuitable to crop production can be used for livestock production with very wide grazing.

Most livestock production is done in hyper-concentrated confinement operations which take up negligible land space. For the wellbeing of the animals, the quality of the environment surrounding these sites, and the quality of the meat -- these confinement operations should be done away with. The space, though, is irrelevant.

Eliminating livestock production increases food availability because the feed-conversion-ratio is between 4 and 40 (how many pounds of feed turn into 1 pound of cow,pig,chicken, etc).

It is certainly not about space.

I think it was like Reader, where the service was so good and ubiquitous that nobody felt compelled to make a replacement.

This will affect a lot more people than the Reader shutdown, and in a way that hits the pocketbook for those that have devices that depend on Shoutcast like my Yamaha receiver. I wonder if the outcry will be as strong?
The article certainly doesn't advocate for removing any constraints; there are just much, much more flexible ways to accomplish them in postgres, some of which offer similar performance. A domain using a TEXT field and constraints is probably the most performant (and flexible).

Another thing is to plan for a solution that can expand. Don't use a data type that requires massive table rebuild times if you ever increase its size. If adding a column or expanding a field takes O(n) time, don't expect n to be small forever. If an operation takes greater than O(n) time, realize that you'll pay that price eventually.

Basically, establish soft upper bounds.

And as a P.S.: don't expect anything sanitized by your application layer to be an invariant. Your database and the rules enforced by it are the only real invariants. If an unexpected character in a name field will blow up your application, you should fix it in the database (varyingly difficul with many RDBMS solutions) or treat it as user input and sanitize/scrub it at the application layer (more common with NoSQL solutions). Ideally, do both!

It would be interesting to compare this in a fair apples to apples way. You'd want to take competing cars to the Tesla of the same age. So how many car fires have their been amongst all the BMW 5/7 series, Mercedes E and S series that are 3 years or newer etc. Then you'd get a similar looking sample size for all the critical elements I would think.
I understand where you are coming from, or at least I think I do. You feel that has comments relegate UX designers to some time type of "second seat" in the software development food chain. And, perhaps as a designer yourself, that to be rather insulting.

But I'm going to put this out there and say your are misinterpreting his comment.

There is a whole lot of "rockstar" talk when it comes to software now; "amazing" engineers or designers that will change your world(TM). It would seem that revolutionaries and visionaries are a dime a dozen now. However, more often then _I_(and I'd argue the parent as well) would like, the whole thing turns out to be nothing more than smoke and mirrors. That type of behaviour bring the whole community down. Its not that UX designers or agile engineers or whatever are bad, they are clearly some of the most valuable and hardest working members of the technical community. Its just that when I see a piece on the next great mind in software, I get this knee-jerk reaction to think "hypppppppe."

Which is what I thought when I clicked the link. But this article plays counterpoint to that world. Here you got a guy, unkept, on his way to being a computer scientist, probably never meet a VC in his life, who is also a hacker. And instead of talk, he is putting forward some rather boring, technically difficult to implement, but useful, stuff. What's more, he is not trying to be like, "I'm better than this company," instead he's got a real grasp on the scale, penetration, and limitations of his work. Its just refreshing.

Perhaps the parent could have worded things better, but I'm not sure he intended to be insulting.
I've seen and used devices like these at various Federal facilities and you stay inside for 3-4 seconds until a guard pushes a button to open the other side. The guards called them scanners and said that they sniff for explosives. These look identical, so maybe sniffing is an add-on feature.

good points.

In terms of the semantics: in the end it's up to people using it. I'm more worried about profiteering than confusion. But it's for the market to figure it out.

I don't think the traffic is significant. caching is very easy - you don't need to have all 10^12 - 10^15 domains on disk and even if the size per record is tiny.

Bugs are less significant than possible collisions and fraud.

They stipulated that the player use HTML5 so that it could show all of their ads and overlays correctly. That seems pretty reasonable.

Microsoft couldn't have just the player in HTML5 because their embedded webview can't play video -- which is where the stories of "Google wanted the whole app to be done in HTML5" came from.

IMO an embedded webview should be able to play video, or Microsoft should have been able to get something together just for youtube.

Imo this would be hard if not impossible.

Mathematical equations don't have any meaning taken by themselves; they just express a certain relationship between quantities without stating anything specific about what those quantities are.

Any translation of an equation to English would be a certain (usually lossy) interpretation of the equation for some particular quantities. But the same equation can have multiple interpretations in wildly different contexts.

Striking example is quantum mechanics. Physicists in the first half of the 20th century figured out a mathematical model (e.g. the Shroedinger equation) that worked perfectly well for predicting the behaviour of fundamental particles. Interpreting what the equation actually means (let's say in English) proved to be hard though and spawned multiple, sometimes conflicting or paradoxical interpretations. In fact, to this very day physicists are split on their favorite interpretation of QM. On the positive side, the mathematics of QM just works no matter how the result or the calculation are being interpreted.

All it takes is for one impending doom, and bam! You'll never again have the luxury of even being able to think about happiness.

Course, most dooms aren't that final, and I agree that we should focus on the positive (such as, how can we change our actions to affect a positive outcome?), and a critical eye towards doomsayers is always called for (as is a critical eye to those who promise happiness), but ignoring problems usually doesn't make them go away (especially serious ones).

Interlocking doors ("mantraps") are a standard and widely-deployed access control device. Here are some commercially available: http://www.boonedam.us/mantrap-security-doors/

The national security policy people who implemented this probably go through one to enter and exit their office every day and didn't think anything of it. They exist in all kinds of secure facilities. (Not necessarily as a glass coffin, but simply a room to which only one door can be open at one time.) Like a turnstile, it solves the tailgating problem - you can visually inspect who is in the room before you let them through, and if someone's face doesn't match the badge they swiped, you can hold them there while you call the police.

As for fire safety, in some areas building code requires that the controller is tied into the fire alarm and allows free egress if activated. There's also almost always a bypass switch/key/code to let both doors open.

A couple of examples I can remember from popular fiction are the entrance to CBS Master Control in The Insider (1999) and the executive suite of Seatec Astronomy in Sneakers (1992). There were a few in the Artemis Fowl and Alex Rider books. There is a mantrap with no access control between the main floor and the butterfly wing at the Milwaukee Public Museum to keep the air conditioning out and the butterflies in. Haven't been there since ~2005, but I remember being locked in it for several seconds before the exit light turned green.

Any Biosafety Level-rated lab has negative pressure to prevent virus from escaping, so there's an interlocking door system between the hot part of the lab and the rest of the building. Electronics prevent both airtight doors from unlocking simultaneously, and you are required to go through a decontamination shower procedure before opening the outer door (not sure if that's enforced by electronics or just training.)

The combinatorial number of possibilities quickly grows beyond what can be tested automatically, so you have to start from good intuitions. That's actually what machine learning is _not_ great at; it finds patterns in data (maybe even previously unknown ones), but arguably doesn't come up with creative insights.
Most things in the world eventually self-correct. But before that happens, many people will be hurt and die in the process.

For example, we could do away with CDC, FDA and building codes, and rely on Yelp customer reviews of drugs, restaurants and electrical contractors. Eventually the ones that kill people should get bad reviews and go out of business - but this won't help the first victims and their relatives.
Some would argue there's a fine line between nihilism (which is often misunderstood anyway) and stoicism . . .

I think of this as similar to how knowledge is freely shared in a coffeehouse. You hear a conversation, chip in your insight if you have any. You do it because talking involves little effort, and you want to share your knowledge. That might be due to a variety of reasons; from trying to prove someone wrong, to a general feeling of wanting to display knowledge.

Of course we should. But an automated warrant officer would also be something new...

Airports seem to have their own notion of legality, so at what point would it detain someone? An international warrant? US felony warrant? US state felony? Misdemeanor? Back taxes? Unpaid child support? Unpaid municipal fines? We accept all major credit cards! You didn't report for jury duty... mind telling us where you live now? And while you're here, we'd like to inform you that your ex-roommate has run afoul of the law... perhaps you've seen him lately? Let me get the investigating officer on the line...

> should we not be able to arrest people we have arrest warrants for?

I was responding fairly specifically to "I have never encountered a situation like this before in an airport."

edit: the operative word in your sentence is "_like_" and "_never_"

My point is, you have encountered systems "like" this, if you have ever exited an airport secure area. And it's the secure area, not the airport building itself.

also; boiling frog analogy is quite flawed
Rackspace Cloud Intelligence: Insights in Monitoring
Building code would almost certainly require a tie-in to the fire alarm so that it allows free passage when there's a fire. If it's like many airports, there would be other alarmed fire exits, and you could easily go under/over the crowd control ropes if you had to.
That is surprising. It's pretty incredible to see a formulation that doesn't involve any advanced Number Theory.

As someone who works in machine learning, I have mixed feelings about this article. While encouraging people to start learning about ML by demystifying it is a great thing, this article comes off as slightly cocky and dangerous. Programmers who believe they understand ML while only having a simplistic view of it risk not only to create less-than-optimal algorithms, and might instead create downright dangerous models:

In the context of fraud detection (one of the main areas I work in these days), a model that is right for the wrong reasons might lead to catastrophic losses when the underlying assumption that made the results valid suddenly ceases to be true.

Aside from the fact the techniques he mentioned are some of the simplest in machine learning (and are hardly those that would immediately come to mind when I think "machine learning"), the top comment on the article is spot on:

> "The academic papers are introducing new algorithms and proving properties about them, you’re applying the result. You’re standing on giants’ shoulders and thinking it’s easy to see as far as they do."

While understanding how the algorithm works is of course important (and I do agree that they are often more readable when translated to code), understanding why (and when) they work is equally important. Does each K-Means iteration always reach a stable configuration? When can you expect it to converge fast? How do you choose the number of clusters, and how does this affect convergence speed? Does the way you initialize your centroids have a significant effect on the outcome? If yes, which initializations tend to work better in which situations?

These are all questions I might ask in an interview, but more importantly, being able to answer these is often the difference between blindly applying a technique and applying it intelligently. Even for "simple" algorithms such as K-Means, implementing them is often only the tip of the iceberg.

Umm, I think he was referring to the (purported) health benefits of a meat-free diet. The ideal amount of meat in one's diet is perhaps debatable, but I wouldn't call the claim "a massive load of shit" (both because it overstates and because I would come up with something more civil).
I used to use a pair of in-ear monitors, a Shure SE210 set. The problem was that, after a few months of continuous daily use, I started to suffer inner ear impactions. Not fun at all.

Otherwise, at the office, I use a $20 pair of Sennheiser over-the-ears that does okay (but I don't care if something happens to them), and at home, my Shure SRH440 are a great middle ground between quality and price.

This isn't a revolving door, this is a round box that keeps you there until the system controlling it allows you to pass.

Revolving doors go round and round and don't usually prevent egress.
