I think accusations of premature optimisation might be a little unfair here.

Ignoring the style issues for a second (I'll pick that up later), if I'm looking at some code and there are two equally viable alternative ways of writing it, one of which saves a chunk of memory* or is faster then it's just perverse to choose the path of larger/slower code. I do this with regular expressions/string functions. I see people use regexes a lot, but the tool I reach for first when doing string operations are the built-in string functions, eg. https://golang.org/pkg/strings/#Contains or https://ruby-doc.org/core-2.4.0/String.html#method-i-start_w.... I'm not optimising, I'm just not de-optimising.

Back to the style issue, at this point if you really feel strongly about the way it looks in the editor, or in documentation then I can see why you would choose one method over the other, choosing the less desirable, but theoretically faster code would absolutely be a case of premature optimisation. I personally don't have a particular preference either way however, and feel like the reasons outlined in the style guide are rather fragile. So ultimately, if I pick up some code full of named return values I don't think it would bother me, in the same way that code that uses none, or mixes them where someone thought it appropriate doesn't bother me either.

* There may be benefits other than just disk/distribution size. Many years ago I read about the benefits of small binaries, something relating to CPU caches, though that may be out of date now and I forget the details.
I predict that this will be the new primary source of propaganda undermining public belief in climate science.

I don't see why would anybody would need to migrate anything to grids. It would be more, use where appropriate. In my case, flexbox fixes more of my problems with css. CSS grids will be a nice addition but that's all.
This Emotional Intelligence Test Was So Accurate It Was Creepy
The politicians spend other people's money poorly so the people elect a businessman to stop spending money. The businessman stops spending most of the money but what he has he spends poorly. The people elect a politician who now only has the small amount of money left by the businessman and is forced to spend it wisely.

I think that is a resounding success.
Completely. Well, ok, not really :) I debated including it because it's not something I do very often. I do think it's true though. On a CD you hold the skip button and have to guess where you are (pretty sure none of my CD players showed a timecode when skipping but it's been a while). With vinyl you can see a physical representation of the length of the track and estimate much better (i.e. the solo is half way through so I put the needle in between these two lines and I should be close).

NB: I'm thinking about actual CD players here, not your CD through iTunes or something where you can click to skip on a progress bar.
Big fan of this too. You can also link to Bandcamp, which offers a range of formats including VBR MP3 and Ogg.
yeah - people who provide services become successful. It's a pretty good system as long as we can keep the less successful people out of poverty. Equality of outcome is possibly the worst idea in history.
The science is bad and the politics are deleterious. That has nothing to do with prejudices on my part; thinking that the methodology and behavior is naively toxic at best doesn't mean I disagree with the egalitarian aims that are claimed to be the motivating factor behind this political ideology.
All of this. Don't control, but do guide.

After all, your kids will eventually have all the freedom of adulthood, and the best thing you can do is prepare them for it -- so they don't end up being one of those college freshmen who have to have their stomachs pumped because they never had a chance to learn there was such a thing as moderation before they left home.

>2. Everyone should be trying to become an entrepreneur. Disruption is a panacea.

This one particularly annoys me. Anytime you hear it you can be almost certain the person saying it has no actual experience in innovation/wealth/job creation. I prefer Andy Grove's take on it:

"Without scaling, we don't just lose jobs—we lose our hold on new technologies. Losing the ability to scale will ultimately damage our capacity to innovate."

The ROK was a wild economic success when it was a dictatorship that tortured and dissapeared political dissidents.

I think economic success has more to do with access to American markets, and being a 'strategic partner' in cold war geo-political games, then it did with your form of government.

Don't judges have immunity from legal retaliation to their actions as judges?
Well, MIT, sure. But is Harvard really a remarkable CS, engineering, or applied science research institution comparable to Berkeley or Stanford?

It's interesting what happens when you look at rankings of engineering programs, especially at the grad level. You start to see more large state institutions, as well as more technical institutions, with a heavier concentration in the mid west or west coast.

The ivies are hardly missing in action, especially Cornell (should probably also say Columbia) but Texas, Washington, many UC campuses, certainly Michigan... I'd probably put all these, certainly at the graduate engineering level, at or above the ivies. And the ivy that really seems to be a heavy hitter here, Cornell, again shows how much things have shuffled up once you go to engineering.

I don't think it's misleading at all. Here is more context:

"The administrator believes that we will be able to recruit the best in the fields which study climate and will organize a specific process in which these individuals ... provide back-and-forth critique of specific new reports on climate science," the source said.

So they will recruit "the best in the fields which study climate" which basically means they will recruit a few of those "scientists" who get paid to reject climate science and put them on the "red team" or whatever, and that team will be listened to exclusively by the administration.

Organic in what sense? Other than "pch" it's much less magical than matplotlib (to me), and its primitives are exposed alongside the convenience functions like hist() with ugly defaults we all love to hate.

I will agree on reproducibility and portability across graphics devices (not to mention actoss installations). Grid takes care of so much annoyance in that regard.
Like everyone else here, I don't think this is a very good example. Even if it were, other languages can do a better job of accomplishing the same goal. For example in Python:

def circumference(r: float, *args, pi=3.14) -> float:
return 2 * pi * r
I don't understand, through these examples, why the introduction of a name is necessary in order that an empty return statement be used.

The name doesn't even appear in the function. A name that is declared but not subsequently mentioned serves no purpose (or some side purpose/hack).

In the "NoNamedReturnValue" variant, the return type is still declared. The compiler could, from that type alone, infer that "return" means "return a representative default instance of that type".

That is to say, why can't Go programmers just have this:

// oi name removed:
func NamedReturnParams(i int) (/* oi */ objectInfo) {

if i == 1 {
// Do one thing
return // wee, allow this anyway!
}

if i == 2 {
// Do another thing
return
}

if i == 3 {
// Do one more thing still
return
}

// Normal return
return
}

Also, why can't the compiler just optimize away the "return Objectinfo {}" statements down to "return", if those really are equivalent.
>If the "best" Lithium Ion cell that China mass produces has poor weight and/or power density, then it has no use in a Car. Cells and Batteries are the #1 issue for an electric car. (More weight requires more batteries to lug around). Cutting back on weight while increasing the power is how you make a superior vehicle.

FYI most non-Chinese EVs and hybrids with lithium cells use commodity cylindric cells that do have atrociously low weight/capacity ratio

Chinese makers were using purpose built brick cells since around 2012, at the time first generation of Chinese hybrids hit the market
I don't know man, maybe you're right. Brando had a hard life. But if you watch the film from which that quote originates, "Listen to me Marlon", he backs it up with his experiences. Like, in one of the first films he did called "The Wild One" he plays this "electrifying" role as a macho dude on a motorcycle who also has feelings too. Brando knew at the time that was gonna make bank, because of all the shit in the news about Hell's Angels.
There's no proof yet, so your judgement is speculative and presumptuous, even if the right answer turns out to be Yxa. The top answer is awesome, and probably right, but who knows for sure? Do you? It's top because of popularity and not because he solved it. Since all answers including the top answer suppose this was a mistake, it's easy to imagine it being the result of a stupid mistake as opposed to one that feels rational. If this turned out to be a stupid mistake and that yellow or something other than Yxa is the right answer, will you reflect on where the cognitive bias lies?
In principle this sort of technique seems like something that could benefit any sort of science, including climate science, immensely. The number of studies with unreproducible, and likely flat out wrong results, is scarily high. (And yes, there is certainly real critique that can happen in climate science, not on whether or not climate change exists at this point, but on details of certain papers, and even topics like "how realistic is the clathrate gun hypothesis".)

Unfortunately in practice this likely ends up being the government sponsoring the same sort of bullshit that the oil companies have been putting out for ages, and not real critique. Red team/blue team is also a unfortunate name given the political connotations...
it is those company's fiscal and legal obligation to put shareholders ahead of employees.

[citation needed]. Seriously, this is one of those things that keeps being repeated, without anyone stopping to go see if it's true before they parrot it elsewhere. It's a safe bet, right? It makes one sound clever, and enough people say it, it's probably true, right?

It's not.
I'm not sure I'd call 15nm 2D NAND "low end." But when those Chinese fab lines were opened, they were cutting edge.

Nearly all the engineering is done somewhere that isn't in China, which was my point.
The IPCC has already done the work of summarizing climate science.

The role of government is to respond to those truths with estimates of the negative impacts and estimates of the cost of mitigation and then come to a consensus around actions.

This is just obfuscation designed to drive a wedge between accepted science and policymakers. Obfuscaters just want to avoid making the hard arguments over their desires to have either zero mitigation or to actively accelerate human caused climate change.

It's a perfectly fine position to hold that climate change is happening but that you don't care. It's not fine to lie about it happening purposefully create and spread lies in the public space.

Just make the argument that the money would be better spent elsewhere.

It is extraordinarily difficult to force a wilful child to do anything. My now-12-year-old daughter was very reluctant to learn to read, but we insisted that she read to us every night from her second year in primary school onwards. It was exhausting and emotionally demanding work that myself and my wife dreaded doing every evening, but now she's a good reader, and enjoys it. Would she have become a good reader anyway? I have no way of telling, but wasn't willing to take the risk that she mightn't, reading is too important

As for homework - in our house it absolutely must be done. It's like brushing your teeth - no excuses, ever. I don't care that it's often useless and boring, what I care about is that their teachers stay engaged with my kids, and staying in the loop with homework is essential to that

What is the sustainability of the minerals that are mined that go into battery production.

All these and more, should all have rock-solid ELI5 answers to how they are being dealt with.

If there is any startup that may want to have a positive impact on the future, figuring out how to deal with battery waste may be a good one...

Yeah, it really is just a matter of opinion and thinking styles. I'm not sure why we're so bent on this idea that we should all do everything the same way. Part of it is self-preservation, I suppose. "I've got 20 years in Java and you're telling me it sucks (and, by extension I suck too)? You and I now have a problem."

But, we keep doing this with any new tech, and never seem to get that it'll all change and matters a lot less than we think. What people raved about 5 or even 3 years ago is now passe'. Call it evolution, and that's probably a good thing. But seems we could have learned to skip the part where we beat each other over the head while awaiting The Next Big Thing.

Funny thing is that no matter which framework you like, the worst thing you can do is not choose any framework. People can't even wrap their heads around the fact that you haven't declared a side.

I have used DB as queues very successfully in multiple projects (as well as "real" queues in others), so your "please don't" is not very persuasive. Some actual argument, instead of content-free "hacktastic" vs. "real product" designations would be appreciated.

And you use "shortcut" like some kind of negative attribute. Of course they use DB as a shortcut, and they should - it works well and even has additional features (transactions with your primary store) that you wouldn't get with separate queue product.

There's lots of words in this article (and design doc: http://goo.gl/EsdTXo ) but it's missing a very simple key points?

1. State diagram: What are the messages exchanged between Producer and Consumer (and how many round trips to confirm a message)

2. At what point does each side consider the message to have been delivered?

3. Has this been tested empirically? (i.e: Setup producer, consumer, and partition/kill each side randomly to see if messages get lost)

The one thing I don't understand is the following. The two parties communicate by message passing. At some point the message will transition to a new state (i.e: delivered). That transition cannot happen on both sides at the same time. So how do you handle the failure of sending of the last message? Do you stage messages until after the timeout period has passed?

Has anyone ever got Pruitt in front of a camera and asked him the following question?

"Contaminants in our air and water cause X billion dollars of added health care costs and lost productivity to Americans every year. Rising sea levels and extreme weather patterns cause Y billion dollars of damage to real estate and crop yields every year. What is the EPA going to do to control these losses?"

I really want this anti-science conservative to answer the question about what he really cares about: the wallets of people who own lots of things. His side doesn't care about "good science" or objective truth, and they don't care about the public's well being. They care about money above all else and I think that's where the discussion should be focused.

Lol.. other than the one side part (turtle anyone?) what you're proposing is a laserdisc. Ie an actual thing. They're not coming back either because they died. Vinyl never died it just declined. Simplicity of playback equipment is a big reason why. Also nothing stops anyone from putting a CD in a 12 inch jewel case or sleeve of some sort.
Also, since most everything is recorded digitally these days, there are almost no "true analog" mixdowns, which means you're pressing a stair-stepped digital frequency onto vinyl.

With the exception of wealthy purists (read: just Radiohead), that vinyl you're listening to is actually the digital recording pressed onto vinyl, not an analog recording pressed to vinyl.

As Senator Franken pointed out, the scientific process itself is a "red team, blue team" exercise, and the settled result of that process, the consensus view of climate scientists, is that human-induced climate change via carbon emissions is happening and is a real threat.

The article title is technically correct, in that at least one of those teams will be on the "critique" side. It is also substantially correct, germane, and honest in implying with its scare quotes that this new effort is superfluous, unless it is an effort to gum up the works with climate denial.
