The rule is saying that a class which does explicit resource management should be doing only resource management and have no other behavior. In other words, only wrapper classes should manage the resource they wrap, and (ideally) no other resource management should exist. That keeps the management work out of the way of other classes.

This has potential but why 3? Why not 2.7?

Also, what about asynchronous operations?
The link you give defines isolation like this: "The isolation property ensures that the concurrent execution of transactions results in a system state that would be obtained if transactions were executed serially, i.e., one after the other."

That sounds awfully close to the definition of serializability he's using.
If you started on front-end around 2004 like I did you've seen the natural progression of plain-js -> Prototype -> jQuery -> Backbone -> Ember/Angular -> React like a slow process that took more than 10 years but it does make sense now.

I agree that learning front-end today must be overwhelming but is the suggested alternative? Do things like we did a decade ago and figure it out yourself?
I won't jump so fast to shame him. There was reason why he said Antares was junk. From the initial report, the falcon self destructed due to non-nominal path. Which ain't same thing though same outcome.
I think I finally got React. Maybe
I think that article might be a bit disingenuous. Elon Musk didn't say that in response to the Antares explosion, he said it several years earlier, and the part that's quoted is pretty accurate to be fair.

When a failure does happen, nobody goes around celebrating it, whether they're competitors or not, and honestly I believe that includes Elon Musk. I believe that on a human level, but even on a business level it's bad, because it reduces public faith in space transportation generally. Nobody likes to see this happen.

Europe's Moment of Truth
There is a lot of money thrown around in commercial space, but it is not a particularly high-margin business. http://spacenews.com/39492orbital-eyes-broader-antares-busin... This cites Orbital Sciences (now Orbital ATK) CEO David Thompson as saying that the profit margin on CRS was about 5.5% and they hoped to reach 6% with CRS-3.
Hm, call me a Luddite or a communist or whatever, but i fail to see how this type of pursuit, broadly speaking, is of any benefit at all to society at large. In fact, i would argue (while simultaneously admitting that i am not an expert / economist, so i am open to comments) that trading this way is dubious to say the least. All i mean is, where is this guy's massive profit coming from? Surely to a certain degree there must be a law of conservation of cash? Is it really only coming from other traders like him, but who in that instance happened to make a bad decision? In other words, i would say it would perhaps not be that bad if the pool of cash from which such traders were fishing were entirely made up of inlay by other such traders, such as would be the case at a casino at a poker table... What i'm trying to enunciate is a vague uneasiness that somehow, making so much cash without contributing anything to society seems... Unfortunate, to say the least? Isn't there something useful somebody like that could do, instead of amassing a fortune by "gaming the market"?

I have nowhere near enough knowledge on the subject to suggest a workable method of regulation or anything like that, but i really wonder how something that boils down to somebody gaming the market (as somebody else said, the only gambling which is legal in all states) to the tune of millions is anything but detrimental.

Are you looking for real experience? (programmers)
I'm launching a new product and I'm looking for front-end and back-end developers. Specifically skilled in at least two or more of the following areas:

- Ruby on Rails
- Ruby
- AngularJS
- HTML
- CSS
- Socket.io
- Payment Gateways (Stripe, BrainTree etc...)

I'm a straight shooter, so it's a pre-funded opportunity, obviously there is a level of risk involved but as you know the more risk the more reward. You will receive equity and I have a direct connection to the largest VC firm in my city (Toronto) so once the product is ready I have the VC's ears no problem. So if they bite - and we can raise funding, we can begin paying out salaries.

If you're interested, I'd be happy to discuss this in more detail over a Skype call.

I'm still a few months away from the actual plunge, though.
An important lesson for the kids is that cutting edge technology is hard. Rocket science is hard. Like a 10% chance of explosions in an unmanned flight and a 2% chance of explosion in a manned flight chance hard.

(Protip: Only put the humans in the safer rockets, and be sure that they are going to so something useful up there, and anyway explain them that this is dangerous.)

Probably in 20, 50 or 100 years this will be as safe as current planes, but today it's a dangerous task.
You seem to be arguing with something nobody said. There's no assertion that WASPs are the only people in the world to have ever decided that one sort of naming convention is normal.

What is being said is that our particular notion of names comes out of that WASP tradition. (Which, if you'll take 30 seconds to read Wikipedia, has important class and wealth connotations.) And therefore it doesn't apply perfectly to an extremely diverse society of immigrants, one with a long history of cultural, religious, and social experimentation.

It's an accident of history that a dominant strain in our culture is "protestants from the British isles". But it's still a pretty important accident. It leaves a mark. We still call that part of the country "New England", for example.
This is really cool, actually.

Thing is, your example fits in with "the natural order of things". No one is surprised that some members of a general group of people are "violent thugs", since there are people who are like that. Ditto "hate filled radicals", and there are observably many Jews in Israel, it was established for that exact purpose.

Whereas there's a mainstream theory that police are there to "protect and serve" the non-criminal population in a Western nation, it's not supposed to be in the natural order that they're e.g. observably eager to kill your dogs given the slightest opportunity.

It's very counterproductive, to the extent they in theory exist to preserve order, it deprives them of vital information. It's extraordinarily short sighted to behave that way, for so called "good cops" to look the other way when "bad cops" do that, in a thoroughly armed society they have no hope of disarming.
I honestly don't understand why people don't just use a fake address then. I've never gotten anything other than spam mail when using a real address on a domain registration. It's not like ICANN can in any way verify addresses.

People who write code in C++ are not doing this because it is fun or just because it is the latest buzzword. They do it in C++ because it is the language that supports the billions of lines of code in their industry, while providing a path forward through new standards and libraries. In summary, code written in C++ will not move to other languages because there is no need for that. The best opportunity for competitors is to write their own new systems and replicate what C++ already has. Not even Java has been able to do that up to this moment. And while it is possible, it will take a long time.

If we take the article at face value, then the answer is that "no, they don't want your full name" for marketing.
The drone operator probably would prefer not to get the authorities involved for a few reasons:

1. It is usually less hassle to attempt a mutual resolution without involving a third party.

2. The local authorities may restrict the use of the drones.

3. It is generally a good idea to be on good terms with your neighbours.

I'm curious why these articles are posted so often on HN. Do a lot of people here have mood disorders? If so, would it not be better to look at the more obvious causes -- lifestyle and stress -- rather than trying to pin the blame on some outside entity?

Right, but $.5x for 1 is not an option.

Scenario 1: 1 for $x

Which yields higher total profit (not % margin)? I think a lot of people including small business owners don't realize the important difference between total $ profit and % profit.
Ask HN: How Do You Date on the West Coast?
I am 31, single, with some depression, and some kind of social anxiety, living in NYC for many years now, and I am planning to move to LA (job offer). As a trial, I am staying now in LA for 2 weeks (shit, I love the weather here!) and I use Tinder to find some dates. While in NYC, I just take a taxi, subway, or walk and within 25 min I meet a girl. But, in LA, it happened I got matches 25 miles away. Taking Uber will cost me $50 in one direction (I am bad with dating, so I need to meet like 10 girls before actually I find one that is interested), so I am just wondering how does people meet here and arrange dates? I drove like 20 miles for a date, then I had to keep in mind I will most probably need to drive back home, so I cannot really have any drinks. Unfortunately I usually need to have a drink to relax and be talkative. Please advice.
I think you are right on the money here, friend. Whenever I'm purchasing something online, I'm always curious how that transaction will take place... sometimes so much as just "test purchasing" the item to see what will occur if I actually decide to buy.
Have you probed around the musl code? I welcome the competition to glibc and think they have some good goals. It's remarkably stark in terms of documentation. memset.c has some good comments, being as how it's not exactly how most developers would implement it initially. memcpy.c looks as if it has none at all...

musl's printf is more clean than glibc's, no question, but it does less though. Only because I've wasted time to look at many of them, it doesn't look bad, but it just doesn't look great either. glibc's is really ugly for 2 big reasons, it has extra sweeteners and then it does some exotic looking shit to try and be fast. I'd probably grok musl's faster but I'd not want to jump in and hack on either of them or debug them.

Some non-canonical constants, stdout instead of STDOUT.. It's a nit, but I remember at least 2 major TLS holes in the last 18 months that were pretty much a result of non-canonical C style; it's a dangerous thing when you do it and start to collaborate.

It looks clean enough from 10,000 feet, and I do admire the competition and welcome it, but it's just another collection of relatively undocumented stuff that implements some mildly exotic performance optimizations, just like glibc, only it doesn't support nearly as many platforms. It means everything in the world if you've run into a glibc bug, I get that, but it's amazing how few people have done that. Both could really benefit from a detailed and complete set of "how and why" documentation...

I agree, but the flipside for me is the various shitheels who use domain privacy to avoid accountability for bad behavior. Spammers, squatters, criminals, network abusers.

Is there some sort of middle ground where somebody like Amnesty International is one of the domain privacy providers? And another is, say, the Society of Professional Journalists? I would totally trust well-established organizations like that to make reasonable decisions about when to keep information private.

Based on that, one can clearly see by stepping frame by frame at 3:20 disintergration of what i imagine must be second stage fueltanks. Difficult to say if it is oxygen or kerosene, but since its expanding so rapidly it would seem likely that its a oxygen tank.

But nevertheless its just guessing from me and im no expert.
Crazy how little actual conflagration there is. I would have expected a big fireball when that much RP-1 and LOX explodes. I mean the entire second stage's fuel exploded.

Often programmers instinctively name their code the same way they structure it: with as much elegance and brevity as possible.

If you think about it, elegance and brevity in naming serve no logical purpose. When reading names, understandability is the only goal; elegance and brevity do not assist in this goal. Thus, from a readability standpoint, it is better for names to be verbose and informative at the expense of elegance.

There are those out there that complain about how verbosity contributes to increased typing time and the probability of spelling errors, to which I have to say: Modern dev tools like Intellisense and autocomplete largely eliminate this type of error. Additionally, if you hate these modern tools, I still feel that, especially in extremely large and complex code bases, the benefits of writing clear and understandable code with verbose naming far outweigh the benefits one gains when using brevity in naming.
Because not everybody uses FB (I don't), or when they do, use a private/incognito window, "sandbox" the session, to avoid being tracked (that is how I use GMail).

I can't be the only one that does this, it takes almost no effort, and using a private window for the really "important" accounts, so you're not logged into them all the time, prevents a whole lot of problems and exploits.
No, I really thought that. I also thought, all sorts of things so I am not claiming to have some sort of predictive powers. It could easily be camera angles and my expectation of seeing the thing zoom off the pad.

Just saw this (https://www.youtube.com/watch?v=24cZYMsdrq0) video. It looks like trouble started near the top of the rocket. Also, heard the Air Force Terminated the flight.
