What lack of oversight? If anti-vaxxers think somehow vaccines got added into the system for the hell of it or purely for profit, that's only going to make them look insane.

You can spread out vaccinations all you want, you just have to ask. Our 4 year old just had her vaccinations, and we chose to have 2 right now, and 2 next year (it is normally a combination of 4 vaccines).

Well, it's immutable. So why would it be a problem with bouncing it around?

It's like a symbol in Ruby -- all instances of, say, :electron point to the same point in memory, they're just used all over the place. The sharing isn't problematic because you can't change :electron.

Why would you want to use 'electron' instead where every time you use it, you put another instance of it into memory?

If validation is the problem, then remember that most developers aren't on HN, and they aren't building startup apps. Also, I can't imagine a developer only knowing the one languages. Leverage other "cool" projects if you feel you really need some geek cred (Javascript MVC, CSS pre-processor like SASS or LESS, automate your builds using Chef, optimize developer experience using Vagrant, implement search using ElasticSearch, etc)

If all you've ever used was PHP and you haven't grown into using the other amazing tools that are available in 2015 (remember, "this isn't 2004"...) that's the bigger issue.
This is exactly the right answer. The lack of credibility of science has provided a foothold for anyone with a plausible idea and good marketing. The "science" that we see today in the common press is just not a reliable source of information. Between academic fraud, cherry picking results, governments failed oversights no one can tell truth from fiction so it's back to our biological dispositions.
younger generations are more tech-savvy, too

Then they aren't your target market, but perhaps older people are.

As the world gets more technologically advanced, the result is that fewer people know what to do when their devices don't work. If anything, the number of people who need your services might be increasing, not going away.
Charlie Brooker Is Right Again. 'Black Mirror – Be Right Back' Made Reality
I would guess that they use more expensive hearing protection systems with an active electronic system to pass through sounds at a comfortable level, attenuate louder and potentially damaging noises, and possibly even amplify quiet sounds.

The technology would be similar to that used in hearing aids and noise-cancelling headphones. But it is also probably an order of magnitude or two more expensive just because the primary customers are tax-funded.

Without electronics, I could also conceive of an earplug with a winding channel bored through it, past flaps that can block the channel by moving too far in either direction and forming a seal with the outer wall of the channel. Sound energy above a certain level would push the flaps closed as the air vibrated, and would thus attenuate louder sounds to a greater extent than quieter ones. If the flaps were tuned to different sound energies, the loudest sounds would push closed the most flaps.

That would require some precise machining to fit inside the outer ear canal. The electronic filter might actually be cheaper.
It is important to distinguish between axioms (things you assume), definitions and theorem (things you prove from axioms, stated in terms of definitions). So, for basic arithmetic, your assumptions might be the defining properties of numbers: associativity, distributivity, etc. In this setting, 1 + 1 = 2 is basically a definition, while (-1)* (-1) = 1 is something to be proved:

0 = 0* (-1) (0* x = 0 for all x)
= (1 + (-1))* (-1) (x + -x = 0)
= 1* (-1) + (-1)* (-1) (distributivity)
= (-1) + (-1)* (-1) (1* x = x for all x)

implies:

1 = (-1)* (-1) (equality; add 1 to both sides)

Finally, slope = rise/run is a definition. It is not something you "see" to be true.

So assumption vs. definition vs. theorem can explain part of it. Another part is familiarity. 1 + 1 = 2 is ubiquitous in daily life. Depending on what you think about, (-1)* (-1) = 1 may not be. You probably have lots of interpretations of 1 + 1 = 2 (counting, number line, shopping, money, etc.) How many such interpretations of (-1)* (-1) = 1 do you have?

You don't need a special, weird distro to run openbox, just use Ubuntu or Debian or Fedora unless you're a masochist.

In the case of Lubuntu, LXDE use the openbox window manager anyway, so even without touching apt-get you can logout, choose a pure openbox session and login if you want, though it takes some configuration to be useable. LXDE seems fine and plenty light enought for me though.
It seems like you are having trouble internalizing math. I think what you mean by "that does not strike" is that you have not yet developed actual insight into what you are learning. This seems to be what you are missing.

So, you need to learn how to develop this insight. It's not easy, but maybe just knowing what you are looking for (that is, to develop intuitive insight into what you are learning) puts you into the right track, and hopefully it gets easier with practice later.

Here are a few resources. Please note that these are not resources for math, but resources on how to develop insight into math.

- Cal Newport's essay about insight in technical college courses: http://calnewport.com/blog/2008/11/14/how-to-ace-calculus-th... (the general idea still aplies even if you're not studying in/for college)

- BetterExplained Math Cheatsheet - http://betterexplained.com/cheatsheet/ (a collection of intuitive, insight-generating explanations on a variety of math topics, from basic to advanced)

- Coursera's Learning How To Learn course - https://www.coursera.org/course/learning

- A Mind for Numbers book - http://www.amazon.com/Mind-For-Numbers-Science-Flunked-ebook... (the book used in the course above)

I hope this helps. A few basic, general tips for developing insight is to think about applications. For example, your slope of line problem. If instead you called the y-axis "distance travelled" and the x-axis time, can you "feel" that the slope of the line is the speed? What if you substitute "distance travelled" for "revenue generated"? What would be the equivalent of "speed" in this case? Try with a few more examples, and hopefully you will develop an insight that the slope of the line is the rate of change of something, and will be able to apply it to many situations.

Sure, but all those businesses will have to deal with large amounts of incoming cash, so they too will have an incentive to take bitcoin. The secondary businesses wouldn't even need to keep any bitcoin as they could use something like BitPay or Coinbase to immediately convert bitcoins to dollars.

But for the primary growers/dealers, having a way of storing their profits without the risk of robbery would be a huge benefit (and probably lower storage costs substantially)

I (American) was born in 1980 and I clearly remember being told that the Soviets and their Evil Empire were going to kill us all some day. It was a time where calling someone a 'communist' was not just a rhetorical device, but an actual insult.

This was a common thread from school, to the news to my family. People were worried about the communists still and the rapidly degenerating situation in the USSR only increased the worry.

If you base your identity on the language of the day, you are going to have a bad time when things change.

I am a developer. I develop in multiple languages, using multiple frameworks, with different technologies, to fill different needs.

Why would I care which language I am using for a project? The syntax is different and so are the built-in tools, but in the end, you are doing the same things.
Nope, every single one of the examples of being used "incorrectly" were being used correctly and also point to the general trend in all languages towards simplicity and regularity. More specifically these are all covered under well known morphological mechanisms that drive English word formation.

For example, in English, verbs and nouns have an unusually close relationship, it's trivial and natural to verb nouns, especially when the verbed noun is obvious. This is an example of derivational morphology, and there's all kinds of ways of doing this in different languages.

In English, among other neologistic processes, there's also a process to compound common noun phrases. These days, compounding nouns usually skips several medial steps (like hyphenation) because everybody knows that in a couple generations we're just not going to bother with the hyphen and we skip all that stupidity. A thousand years of English has showed us that this is the pattern.

Verbing a compounded noun is not only correct, it's actually how English works.

What happens in this specific case, is that these are all examples of incompletely verbed nouns. You don't say "setupping" you say "setting up" and that's because the phrasal verb form is still in common use. Once it goes away, we'll all be saying "setupping" and a few internet grammar nazis who are caught in a linguistic time warp that's literally decades behind every other person around them will get all hot and bothered that people are participating in these completely natural linguistic processes.

Verbing weirds language.

A very good private party DJ(He plays for artist and actors) told me that if you want people to dance, the volume must be very high.

As it was my party I told him to do it as he saw fit and indeed almost all the people (200) danced.

Then one neighbour complained and he lowered the volume (just for a while ;) ) and most people stopped dancing almost immediately. When he boosted the volume again, they all jumped to dance.

It was amazing.

Edit: Typo.

Reply to the comment below: I understand your comment, but the party was in a former s.XIX coastal battery fortress,(now an environmental Hotel). This fortress is excavated on the stone , below the ground level (You don´t see it till you are literally falling in the ditch). The place where the Party took place was 10 meters below the ground level, behind a fortress wall, a 6m high ditch and 1.5 km away from the nearest buildings, separated by rolling hills and Mediterranean woods.

No, sorry but I certainly was not that worried of the volume and the neighbours.

Yes, it should be forced. It's the same as allowing people to choose if they want to participate in taxation. It doesn't work because of free-riders.
> At this point, probably the best we can do is to so relentlessly ridicule the position that it becomes an embarrassing opinion to hold

I'm so sad that this is a solution for so many things these days. Science isn't the social justice movement, we have evidence. If people want to bully others for being racist or homophobic, whatever, but that's not how science works. All we have to do to "win" the argument is deescalate it emotionally and make it about calmly and rationally looking at the evidence. That's how science wins, not by marginalizing anybody who disagrees with us.

And when people ask how we know that science works, point at all the technology of the modern world. The phone in their pocket, the airplanes they fly in, the toilets that make their poop disappear, the International Space Station floating around the earth, the electricity in their wall sockets. We don't place blind faith in science, we believe in it because it works.
* "git push" into a repository with a working tree normally refuses
to modify the branch that is checked out. The command learned to
optionally do an equivalent of "git reset --hard" only when there
is no change to the working tree and the index instead, which would
be useful to "deploy" by pushing into a repository.

Nice! This sounds like something that I expected Git to do since the first time I used it, which means that I ran straight into the unfriendly error messages that result from pushing to a checked-out repository.

Using hooks for simple deployments has always seemed clumsy compared to the thing that I originally imagined Git could do. I'm glad to hear that Git now supports this use case.
Thanks for your perspective. As a new grad, I sometimes feel guilty reading HN comments because I'll dwell on why I couldn't also "go to MIT and make a startup at age 22" or some nonsense. It's good to hear that not everyone here is a 10k-a-day coding savant.

The 30 Most Common Ways You Can Lose an Argument
> I've been to standup meetings in close to a dozen different companies, ranging from the smallest startup to some of the biggest tech companies and never have I ever seen a standup meeting end on time. NEVER. I don't think it actually happens.

It's easy to sabotage standups in this manner by asking questions of others that you know will cause extended discussions. Especially on topics that have previously been "settled" by fiat.
It's honestly a shock to me that instead of trying to be more open minded you accuse the person of being "not as good as [he/she] thinks [he/she] is"; let's try our best to remain civil here please.

In any case, I believe you two just have a misunderstanding. It sound as if you believe a "good" developer is one who is consistently capable of producing quality work, whereas the person you are responding to considers a "good" developer to be one who is capable of producing quality work. In my experience most people also share the second definition but that's besides the point.

I can't imagine it's hard for you to believe that if we consider someone is "good" if they are capable then being good has nothing to do with their level of motivation which is directly affected by their workplace. That being the case, obviously any developer will produce to varying degrees depending on how well they fit with their company, or probably more accurately their team.

"in fact, this is a moot point, because good developers don't stick around to try to produce work in fucked up companies."

Why? There isn't some discrete separation of good companies and "fucked up" companies. There are good companies, bad companies, and companies of all levels between. And even in companies there are good and bad teams. Just because a great developer doesn't perform on one team doesn't mean it's the team's fault; it could just be a poor match.

I was thinking the article would be about the incorrect singularization of the word 'data'. It's a curious case. When I hear people say "these data are...", I can't help but think it's pompous. Even though I know their usage is correct!
I use the `man` system. When you invoke `man` you can pass an optional leading argument indicating which "section" of man pages you want to see, e.g. `man 1 open` and `man 2 open` give different pages.

You can add new sections by setting $MANSECT. So I added a new section named with my initials, pj:

export MANSECT=1:n:l:8:3:2:3posix:3pm:3perl:5:4:9:6:7:pj

You can also change where the `man` command searches for manpage files using $MANPATH:

export MANPATH="$MANPATH:$HOME/man"

Now you can just `mkdir -p ~/man/manpj` and start adding files with a `.pj` extension, like `postgres.pj` and `bash.pj`. Then it's super-fast to bring those up by saying `man pj postgres`.

Of course you would substitute all the above with your own initials or whatever.

You don't even have to write the files with the usual formatting macros. Most of the time a plain text file works okay. But it's kind of fun to learn enough of that to get by: probably less than a dozen macros for paragraph breaks, underlining, etc.

And then you can put your collection of notes on Github like here:

>We were having the local college print things for us for $150/pop.

Care to expand on this? I've been playing with the idea of buying a couple very nice 3D printers and starting a 3D printing company. I think a lot of people have been burned by the consumer-level printers or simply need bigger or higher quality prints. What are you guys printing? Do you feel $150 is a fair price? What is the turn around time? What materials? Does that include delivery?

My gut feeling is a local company with local delivery and quick turn-around could be more tempting that going with one of the web-based providers who take days.
One of the issues with newer switching/routing gear (if you want to call it issues...) is that they have to work at such incredible speeds that they are unable to actually keep up with verifying packet integrity before shooting it down into the next hop.

If you want 10 Gbit/sec line rate, one of the ways to do that is to simply forego any and all verification that packets are not corrupted and shove it out of an ethernet port as fast as possible.

I recently ran into this at work, we had some issues with corrupted packets, and we ended up tracing it down to a Twinax cable that was failing. But every single switch in the path to the server happily forwarded the corrupt packets.

Luckily Cisco has some internal counters that show issues like that, and after tracing it down multiple switches/routers we found the culprit and fixed the issue!
I'm smug enough to point out that it's holier than thou.

Herd immunity breaks down when you make exceptions for people who have no actual need for them (e.g. people with a functional immune system). Allowing a more lax or rigorous vaccination or endangers those who are unable to be vaccinated (immunodeficient, infants, etc.).
Crowd-sourced Data Exploration of Tim Hortons Roll Up the Rim to Win Contest
If we consider memes, satire and parody could be ways to prevent certain ideas from being able to take hold in a person's mind. Once you realize the absurdity of a particular viewpoint (taken to its logical extreme), it's harder to be convinced of even more moderate takes on that idea/philosophy/whatever.

Consider people who grew up or lived under authoritarian regimes now living in countries like the US or UK. Seeing the current surveillance trends (well, not current it's been going on for a while), they may be less likely to consider what's happening as a positive. While those who grew up in the US or UK may have a harder time recognizing the negatives because they lack the relevant experience (and, hell, given how little of history my younger coworkers seem to know they won't even have the benefit of second-hand experience).

> I'm not a doctor, but if the rest of us vaccinate our kids, won't they NOT GET SICK?

No. Many vaccines are very effective, but not 100% effective. In addition, while vaccines are generally safe, there are people people that are not "anti-vaxxers" (or their children) who are not vaccinated, including those two young to receive a particular vaccine or those who do to particular health condition cannot safely receive a particular vaccine. General vaccination not only reduces the probability (but not to zero) of those vaccinated getting sick if exposed to the disease, by doing so it reduces the probability of them exposing others to the disease.

If vaccination is not general to all those who can safely receive it, its effectiveness in preventing disease both in those who are vaccinated and in those who are not vaccinated is reduced, because both the vaccinated and the non-vaccinated are more likely to be exposed to the disease than they would be if vaccination was general.
