Visiting Buenos Aires, I noticed the patrons at a vegetarian restaurant were fatter than usual in that famously meat-centric city. (I went there three times.) This is just an anecdote, I know.

I agree that a good vegetarian diet's probably much healthier than a standard American one.
I understand from the article that the img srcset was somehow horrible, but the following (presumably the WHATWG proposal) looks more intuitive to me:

<img src="small.jpg" srcset="large.jpg 1024w, medium.jpg 640w">

Can someone explain the drawbacks?
Yes. And so good that the tools I use to deal with PITR are actually just wrappers over those 2 commands.

But how you orchestrate the recovery process, test the recovery process, centralise your backup files for faster tar/upload to offsite storage. All these things are "not simple" when all you have is the Postgres docs.

Postgres is more than just a database/database engine. Its a database ecosystem.
the <picture> tag is set up very similarly to the audio and video tags, so I think that even if this specific solution isn't general, the pattern can be applied generally to other types of media.
The interesting thing to me is what exactly Blizzard Entertainment said that prompted the author of this blog post (a Google research lead) to decide not to release the utility that at Defcon he said he would.

Excerpt:
"Following Defcon we had a series of conversations with the Hearthstone team about our research... they were very concerned that our real time dashboard that can predict your opponent’s deck will break the game balance by giving that person (that is, whoever has the tool) an unfair advantage. They also expressed concern that such a tool..."

There's no evidence his utility was derived from reverse engineering or a TOS violation. It appears to be based on evaluating a large number of Hearthstone matches and using those results to create a mathematical model that lets you find "undervalued" cards. One application of the model is a utility that can help to predict "what your opponent is going to play based on previous turns." https://www.elie.net/blog/hearthstone/how-to-appraise-hearth...

Blizzard has taken aggressive legal action before. As EFF tells it, Blizzard filed "a DMCA lawsuit against a group of volunteer game enthusiasts who created software that allowed owners of Blizzard games to play their games over the Internet. The software, called "bnetd," allowed gamers to set up their own alternative to Blizzard's own Battle.net service." https://www.eff.org/wp/unintended-consequences-under-dmca

This time, I wonder if the decision not to release the utility was prompted by a friendly query from a Blizzard developer or a C&D nastygram by a Blizzard attorney -- with a lawsuit threatened if he didn't comply.
The Snowball Effect
Materialism abounds in China, but the average middle-class lifestyle is frugal by American standards.

There are a handful of small, expat-owned software agencies in the major Chinese cities. These are your best bet for getting the type of job you want. Chinese firms in general will underpay and overwork their software engineers. Most of the computer science grads are focused on learning enterprise-y stuff like Java and .Net because that's what big companies want.
I've seen a huge uptick in spam email the last few days, and although I have no indication that I've been hacked, I feel as though I should probably fear for the worst and aggressively change all my passwords from their current kindergarten security levels. Is there a widely accessible, secure, multi platform, free/libre password manager that is recommendable as easy to use? I reuse passwords because its easy to remember, and I'm hoping there is something out there that is light years better than those I found the last time I tried (2007).
What is the proposed usage for these drones if I may ask? I don't want to be a pessimist but if these drones are supposed to be transporting anything of value wouldn't that encourage shooting these things out of the sky?
From his article:

You can calculate the derivative, or rate of change, of a function f by doing

(f(x+ε) - f(x)) / ε

and then at the end throwing out terms involving ε

---

To be clear, this formula is typically introduced as the finite difference formula in calculus instruction.

But differentiation of polynomials is straightforward, so don't be too impressed that a simple formula finds the derivative of x-squared in his example. A bunch of simple procedures find the derivatives of polynomials.

For more complicated algebraic functions, like rational functions, nearly every calculus student is taught a collection of shortcuts that are fundamentally taking the limit of the finite difference formula as epsilon (or "h" commonly) approaches zero.

Wanted: QR code based inventory tool
I have a business that has 5000 unique items that go in and out of inventory each month. Each item is already laser etched with a QR code that is encoded with a unique serial number. I'd like to find a cloud based app inventory tool to track when items go out and come back in.

Any suggestions or does someone want to build this iOS app?

The initial scan would have to import the serial numbers. I've got an app that will handle everything else but requires me to physically enter the serial #s on the front end and I simply don't have the time to do this.

This is a good reminder that we all need to encourage our friends, family, and colleagues to not use the same password everywhere. Almost all of them currently do.

The best solution I've found thus far is getting them to use 1Password or the like. They still only have to remember 1 password, and the browser extensions make it trivial to log in different places. If necessary, buy them the software.
I think (outside of the other effects mentioned related to being health conscious) that protein restriction has something to do with it.

Autophagy may be an important cellular cleanup process that never happens with three square meals a day.

The idea is plausible and there is some early research on this, but there's definitely not a consensus. I personally try to fill this void with intermittent protein fasting on a diet that is otherwise composed of meats, fruits, and vegetables.
> Want to lose weight? Eat fewer calories than you burn. Want to gain muscle mass and tone? Work out regularly. Etc.

This is why research about diet is important. Animals are complex systems, and rarely are "simple" explanations correct (or correct enough). What we know about about food and how we process it is remarkably incomplete considering how important it is to supporting life.

So with that in mind, I'm excited that the prevailing view of diet, nutrition and health in our society for the last century or so is getting challenged, just as science should be challenged and overturned ("disrupted" in SV parlance) in the face of new, better, more sound evidence.

What's coming out of this new research is that, perhaps, the mechanisms concerned with storage of energy (fat) are unconcerned with the rest of what's going on in the body. That perhaps the reservoir of energy available to your muscles and brain to burn, intentionally and with conscious control, are in competition with a sometimes overly-aggressive energy storage system.

It reminds me of how the U.S. does income tax - it comes directly out of your paycheck, before you can even think of spending it. Even if you wanted to go negative, the Govt still gets theirs.

And let's say that the regulator of storage vs. use is controlled by the kinds of food that you eat... that, stretching this metaphor, your income tax bracket was affected by where you worked, or where you got the money from.

Anyway, a more complete picture of how our bodies actually function is a good thing, and the more people try these "fad diets" is actually a boon for the people studying them. ;)

(As an aside - the gluten free craze has helped a lot of people who actually have celiac disease to have more options in eating things that don't taste like crap, or, you know, eat out once in a while.)
My wife works in a hotel (housekeeping) and she tells me the same thing. Every week she has to go with great care through her payslip to check if she's been paid correctly. When they've made a mistake and we contact the hotels finance department it's like; "Oops, sorry." but my gut feeling is that they do this on purpose. Imagine, scamming thousands of employees per week on few hours here and there, must be quite a saving.

according to the article it was the former. And considering that the latter would be even better PR for the authors, I would assume the article to be true.

Well, often if those running a corporation do not have profit maximization as their primary goal, they are voted out by investors. Essentially, maximizing profit becomes the job of the leaders as requested by those invested. There are some exceptions where corporations are profitable by targeting towards environmental things, or other causes, but the bottom line of profit is still there... Especially so with larger corporations.
You're example is not a static typing issue. It's a feature of the library that the struct field doesn't have to have the same name as the form field.

I think the issue is more of a DRY thing, which could maybe be fixed with something like:

type User struct {
FirstName string `form:lowercase_hyphenated`
LastName string `form:lowercase_hyphenated`
}

This hypothetical syntax would instruct the library to look for the form fields "first-name" and "last-name".

Weight loss is psychological, so if you feel like shit the diet is not good at all and not working for you. If you can’t keep your motivation up all the rest is completely worthless.

What I did and still successfully do is calorie restriction (that made me feel crappy for about a month or so, but now I don’t feel crappy most of the time) combined with lots of experimenting around and cooking of different foods to see what makes me feel happy and full.

(Non deep-fried) potatoes, salad, white meat (turkey, chicken) and (garlic) butter do it for me personally. Meals with those ingredients will make me feel full. Sometimes I still go for pasta and pizza (my favourite foods), but my desire to feel full automatically seems to override that by now. Maybe pasta and pizza is something I will go for once a week or, but no more.

Maybe it’s different for you. Just try different things. Also, it takes some time to get used to a new diet, especially if you eat less calories. It took a month or so for me. Maybe also try being active? I found that being active – going on a long walk, driving the bike – gets completely rid of my hunger for some weird reason.

In the end I’m just guessing – but dieting is all about how you feel. That’s the most important thing. You have to stay motivated, otherwise it just doesn’t work. So keep that in mind.

That we don't know whether software development is subject to economy or diseconomy of scale stuck out to me.

Estimation cost (of doing the estimation, not consequences of estimation) not mentioned. Is estimation itself significantly costly relative to subject of estimation?

To the extent open source works relatively well as a development practice, how much of a role does suppression of estimation play (assuming there is suppression; harder to even pretend to hold anyone to an estimate without a contract, so why bother)?
> Twitter has, for me, become a news stream and very little more.

It has for me as well.

I just checked and I have tweeted exactly once in the last year, it was when I was on vacation in march. Before that, it was August 1, 2013.

However I still frequently use twitter. I have a highly curated followers list which results in 70-80% of the tweets I see being relevant to me. When I am waiting in line, or waiting for my food at a restaurant if I'm eating alone, or am just bored, it is a great way to get highly curated content without having to do really anything.

I don't know if I've ever said this before, but some of the comments on the article itself are pretty spot on.

> I can´t see where is the problem with a platform in which you can choose who to follow and what tweets you ignore/pay attention to ??? works just fine for me. I devote some time to "edit" twitter, I mean MY twitter.

> The great thing about Twitter is that if your signal:noise ratio is wrong, you have no-one to blame but yourself: resolute use of the Unfollow button cures all ills!

It's kindof like reddit, if you unsubscribe all the defaults and follow topics you are interested in (some of which get crazy specific niches and have relatively active communities for how specific a niche may be) your experience will increase ten-fold.
I quit my Job to teach Angular
I'm wondering how factually accurate the story is, considering that it says "Apple's Tab Atkins" while both Tab Atkin's homepage and Google+ profile say he works at Google.
Seems a bit tin-foily, they state in the post:
"...they were very concerned that our real time dashboard that can predict your opponent’s deck will break the game balance by giving that person (that is, whoever has the tool) an unfair advantage.

They also expressed concern that such a tool makes the game less fun by taking away some of the decision-making from the player."

Nothing in there indicates aggressive legal consequences for the author to me.

It seems fair enough - it's a game, and anything that would ruin entertainment value for players is obviously not something that Blizzard would want released.
Certainly was with the Apple-Google deal, if we need a more relevant tech-related case.

I recently quit a startup since 60 hour weeks were expected. It made me do a hard self-evaluation and come to the conclusion that no job was worth that for me.

40 hours is an arbitrary number. I think whatever hours is fine, as long as both parties agree on it and are up front about it.
This is a great course on starting out with Angular since it helps you build a real product!
To be really straightforward with it: your post calls for censorship, both self-censorship and the institutional kind. It is your burden to point out why you think using zhis material in illustrations of a technical claim deserves censorship, and if you overstep the line of what is reasonable, you deserve as much criticism as the person you would want to censor.
To be sure, persons (not bodies) can be objectified ... as a means for attaining power, money, sex, whatever. As one person pointed out, the actual contents of the pictures didn't matter to most HN readers, it could have contained gay-specific material and still have the exact effect ("whoa, splitting into three b/w channels"). Was there any objectification involved in the student using these photos to illustrate this point to us? I guess not. Should we be sad that this guy didn't have any pictures of food or sunny beaches that looked recognizable in black and white? Probably yes, even though calling for public ostracism and censorship would be way over the line.
Other NYTimes coverage puts the obscenity of wage theft in much clearer terms:

> One of the causes of this epidemic of wage theft — which, according to Mr. Lafer’s E.P.I. report, involves sums “far greater than the combined total stolen in all the bank robberies, gas station robberies, and convenience store robberies in the country” — is lax enforcement of the country’s wage and hour laws. In 1941, there was one federal inspector for every 11,000 workers. As of 2008, there was one for every 141,000 workers. “The average employer has just a 0.001 percent chance of being investigated in a given year,” Mr. Lafer estimates. Because there is so little risk of getting caught, one-third of all employers who have been found guilty of violating wage and hour laws continue to do it.[0]

Hourly labor laws are ridiculous. And saying that 60 million workers hourly are harmed significantly understates how awful these laws are.

> According to one multicity study, in a single week, nearly two-thirds of low-wage workers had, on average, 15 percent of their pay stolen by their employers.

60 million of today's workers will lose wealth that could compound into more wealth. Then there are the million or so new workers who will join the workforce at the end of the year. In four decades of poor enforcement, a hundred million people have been harmed, two-third of them losing 15% of their paychecks every week that could have compounded over those 40 years into meaningful life savings.

I think you've missed the point. You're correct that one can do basic calculus using a bunch of ad-hoc shortcuts, and it is commonly taught this way. Also, as you probably know, calculus was first formalised using limits not infinitesimals.

However this theory of infinitesimals is not ad-hoc. It is a complete and rigorous alternate formulation of calculus in terms of an extension of the reals, known as the hyperreals, that includes infinitesimals. This allows computation in a principled way that matches the intuitions on which beginning calculus is often taught.

It's pretty cool stuff, and worth reading about even if you never use it in practice.
But it has 468 vulnerabilities patched! I wonder how they inflated this number. I'd bet a lot of it comes from Samsung customizations, meaning you get pretty good protection just by flashing an Android build that's closer to Google releases. Also, if there are serious vulnerabilities among that number, it's a bit disappointing that they took an open-source project (well, such as Android is) and horde their fixes under this license.[1] It sounds like they don't even permit you to flash your own build ("to compile it solely for the purpose of comparing the compiled version to the binary code provided by GSMK")

> Where are we with replacing the password?

What about you load a site, get an HTTP 401 response, your browser sends back an auth header with a password generated for that domain name, based on some secret global key/password. Then in response, most sites would set a cookie. To change the password, you could have a second header that has the new password, along with the original. No usernames needed. The browsers would have a global password for cases of shared computers. Log out buttons on sites just remove the cookie. Or without cookies, just have the browser send the auth header each time until a native log out button is pressed.
