There might be some interesting applications for a device that passes two things, say a fluid and a gas, in one direction and resists the fluid (but not the gas) in another.

Yes they usually do, but most of the time that's not even necessary, because they simply start sending from a different email address and the first time I reply they are automatically entered into my address book.

If someone creates a new Facebook account or switches to G+, I'm not notified automatically either.

here's what i do, i use button tag where it has to look like a button and use a link where it has to look like a link. Also if link requires an eventhandler instead of href change i simply omit href attribute altogether and write my css to apply to a tag irrespective of weather it has href attribute or not. problem solved.
"I decided to roll my own in this case because I was interested in learning about email handling after watching this great railscast from Ryan Bates. And because paying $9 per month per user for something I could probably write myself in a couple of hours seemed silly."

I find myself having to fight against this instinct almost every day. There are a couple of problems with hacking for a couple of hours to save a few bucks a month.

Firstly, you now have an additional piece of software to maintain - you're committing yourself to an unknown quantity of future work.

Secondly, your software won't get any better without you actively improving it. The nice thing about software you pay someone else for is that it gets better over time.

It's a tough instinct to fight though. Building things is Fun. It's just that there are probably other things you should be building that are more important to your company.

If you want to max out on hours, sure. If you want to max out on quality I disagree. I find my work is incredibly better due to the communicative nature of the open plan.

I also find as a designer this is far more acceptable than when I worked as a programmer.
"But those sources you list describe several types of check valves, all of which have moving parts."

Most all check valves use moving parts; the Tesla Valve is novel because it does not.

I added the sources for those that might want to satisfy their curiosity when thinking, "I wonder what type of device a Tesla Valve is?"

Although the Tesla Valve does not use moving parts, that does not mean that it is not classified as a check valve. Tesla's descriptions from his patent [1] describe the valve as only permitting flow through it in one direction, which is the essential operation of a check valve:

"[...] a series of recesses or pockets with surfaces that reverse a fluid tending to flow in one direction therein and thereby check or prevent flow of the fluid in that direction." (Page 5, Item 3)

"[...] and thereby check their progress when impelled in the opposite sense." (Page 5, Item 5)

"[...] reverse such fluid impulses when impelled in the opposite direction and check their flow." (Page 5, Item 6)

Not to sound pedantic, but in this case the "user" data wouldn't have existed without the product, so it's not exactly like an artist's work. It's not surprising it is a challenge to find a traditional parallel for the new complexities of this century.

Wait… Facebook is a… business?!

Seriously though. Facebook is a for profit company. I don't really think thats wrong or even ambiguous?
Anything (sufficiently creative) you create is automatically copyrighted by you, but according to Facebook's terms of service,

you grant us a non-exclusive, transferable, sub-licensable, royalty-free, worldwide license to use any IP content that you post on or in connection with Facebook

Though it's an interesting point; the Facebook ToS are a pretty weak way of effecting a copyright license, even worse than a click-through EULA.

I'm guessing they wouldn't be dumb enough to do so, but it'd be interesting if they tried to exploit that license grant to its maximum potential. For example, a number of musicians, and even major labels, post music videos on Facebook. If we take the terms at face value, that means Facebook gains a transferable license to use that music video, worldwide and royalty-free. So they could, for example, sublicense the video to be used in a Levi's television advertisement, without the original artist being paid--- if this license really does what it claims to do.
I've received one of these emails as well. Almost makes you wonder how much would offline university degrees be worth in a few years.

Objectively, this is not a new idea. We have been talking about revolutionizing education for years - and free online education is pretty much the ideal. There is even enough material about most scientific fields and areas of study (some are more open than others, though) to become an expert.

So what is the problem? Becoming an expert with enough authority for people to actually listen to you. Easy enough to do it on your own in programming or entrepreneurship you might say. Not so easy in medicine or biochemistry (though I will admit I have no first-hand experience).

In that regard, certifications are a significant next step, provided that they get wide enough acknowledgement. That is the next battlefront, I think - convincing industries, governments and academia that online education is the way to go.
I think the best thing is to cycle through a workspace based on what you are doing. As long as you can work on and laptop and out of 1 bag, you are pretty much set.

This can also help prevent workplace injuries as you are not always sitting in the same position. The way I work I get to sit in multiple ergonomic chairs, a standing desk, and even laying down on a sofa.
Your father not handling the situations properly is irrelevant to what the article debates. The key detail here is that French parents aren't actually trying to discipline their kids, they're trying to educate them. They're teaching them to be polite and respect the people around them, they educate them how to behave and interact with other people and this is high priority principle for them. Although it isn't possible to have all the parents of a nation to always be right and always handle things correctly, having the above principle, it does make an overall better adaption of kids to society.
I think this is a terrible headline that masks an interesting philosophical debate. Especially at this community, we feel we intuitively understand that we get the convenience and social value from Facebook for $0, and we pay in our personal data they use to serve up advertisements. That to me is hardly newsworthy and a relatively uninteresting piece.

But- there is an interesting question in what is an appropriate use of our personal data w.r.t credit ratings, financial decisions, etc... Just like there are anti-discrimination laws that prevent mortgage servicers from altering policies based on race, perhaps there should be other walls to keep separate how our data can be used financially.

This is a question the NY Times should've posed instead of this clearly linkbaity uninteresting headline.
that's true. but then again, how much would their service be worth without the user's generated content?
A to Z searchs: Beauty Tips from Picasso
Go 1 Beta App Engine SDK now available
Talking to people who have come to the UK from Europe and America I've been told many times that we are lucky enough to have some of the best television in the world. I'm very happy to pay my license fee and contribute towards the BBC. We do have some very excellent documentarians Adam Curtis being one of my personal favourites.

It may be that I'm something of a spoilt brat complaining about my toys being taken away, I grew up with excellent weekly factual documentary strands like Panorama and Arena, and Tomorrows World which was not a documentary but a fondly remembered weekly science show, now cancelled and not replaced. During the last decade the overall frequency and quality of these shows has declined very sharply.

Documentaries used to trust their audiences, but now quality is apparently judged by viewing figures alone the public service content of any channel has to fight against entertainment programming and they've slipped too far towards entertaining the audience viscerally rather than mentally.

Documentaries are now filled with fluff and sensationalised content and do not treat the audience with the respect they once did. A brief example being a 2010 Panorama doc about CERN and the LHC which felt like it consisted solely of asking as many scientists as possible 'Is the LHC going to cause the Earth to be eaten by a black hole'; For an hour.

[edit] I tend to think this is happening mainly in sci/tech programming, the humanities are still well covered.

Also I realise this might sound like I'm complaining about factual programming as entertainment. I realise that it should entertain and be accesible to an audience new to the material. I'd just like it if they remembered to slip in some facts now and again.
I see this exact same post by mr. simonw duplicated below, as "link [dead]". What's up with that?
I doubt that even the complete record of your online activities would be found by a court to be copyrightable. While it might represent a lot of effort, the fact that the record exists is ancillary to the reason you keep adding to that record. The fact that you don't have access to most of what facebook collects about you puts a snag in the argument that you're doing it for creative purposes.

Copyright for databases or collections of data is variable, depending on the legal framework where you live.

In the EU, there is some protection but it requires either creativity going into the compilation, or the work done to create the compilation must exceed a certain threshold:

http://www.esa.int/esaMI/Intellectual_Property_Rights/SEM2M2M26WD_0.html
http://en.wikipedia.org/wiki/Database_Directive

In the U.S., there is no protection for a compilation of data just because you put work into the compilation:

http://www.bitlaw.com/source/cases/copyright/feist.html

In any case, the basic pieces of information about you are not copyrightable, even in the EU. They have adopted privacy laws to deal with personal data.

There's been some discussion on HN about copyright of public transit schedules, I believe in Australia and/or India.
...polls our pop3 server once per minute...

This is the hacker way? Was it designed? It is not elegant. I think it was grown. It uses technologies which are cool and hip but also dependent on third party services.

POP3 is not a reliable delivery protocol for unique messages.

I'll leave it at that.
Using infographic for analytic
I meant it would be ridiculous to even consider in my circle of friends.

Facebook is used by everyone I know because it is convenient. It is easier to chat with people, message them, and post photos to them, on Facebook that it is to email individual people. e.g. if someone posts a photo we can all comment on it and discuss it together. With email this is not really possible.

The only reason a lot of my friends have email accounts is because they need one to sign up to online services like Facebook. They do not even check email. It is just a box with thousands of unread friend requests and spam messages. That is why it would be ridiculous to consider quitting Facebook for me. I would be cutting myself off. Obviously I would still keep in touch with friends via phone but we would engage a lot less.

I posted this on the blog but I'll copy it here as well. Please forgive the shameless plug.

I think the OP is right in that wanting to automate repetitive tasks is inherent to humans. And the problems discussed in this post are exactly the kind my startup http://loggur.com aims to address. The goal is to let non-programmers automate and also to let programmers automate certain tasks (mainly data manipulation, analysis, triggers, and reports/notifications) in a fraction of the time it would take to otherwise hand-code it.

I should also mention that I am fully aware that what Loggur attempts to do is far from new, but I have yet to see an implementation that isn't a pain to work with. And it's designed with the current (and predicted future) state of things in mind and to be flexible enough to adapt to whatever the needs of the future may be.
I agree with the sentiment (TMTOWTDI), but I also think that it’s hard to stifle an interested mind. My parents let me alone to do what I pleased when I was little (play with LEGO, mostly) and that self-sufficiency carried on.

Later, I wanted to program computers, so they let me. I talked on shady IRC channels learning about network security and operating systems, and that was fine. The important thing is that there were boundaries—no giving away personal information, for example—and the ever-present ability to ask for help if I really needed it. Perhaps it’s not about refraining entirely from breaking the rules, but rather about learning which rules are okay to break.

'The Herbalist' - a real life story
This was also my immediate reaction, agreed. I wrote an article a while ago that talks about a similar thing, but concludes more along those lines - facebook offers us the service for free, and as far as we know they do not sell our personal data. Until they do, we don't need to worry.

Well, he couldn't (easily) have a Turkish girlfriend in the 50's. On the other hand, for perspective, he would be welcomed, as an American, in most (if not all) of the islamic countries. You know, like all those expats living in Tangier.

Also: segregating not by race but by income, trailer folks and poor blacks are still effectively not allowed to live in the same neighborhoods as rich white folks. And not only because they can't afford it.
Part of the problem right now is that online education has such a bad rap - for example, The University of Phoenix is widely recognized as a degree mill. It remains to be seen whether companies/institutions (like Udacity) can get the certification part good enough that it will be worth something.

Young people use it. They don't use email. I'm 21 and my friends are all roughly the same age. They have a university email account they use for school. They have a personal email account, which they set up almost 10 years ago, and only use to sign up to sites. It is filled with thousands of unread notifications, friend requests, and spam messages. They never check it.

The last time these people gave out their email address was in the early 2000's so I could add them on MSN. In the last 2 years anytime I meet someone new we don't exchange phone numbers or email addresses. They ask "Are you on Facebook?" and we connect there. This is becoming more and more common. I'm not saying that it is impossible to get by without Facebook just that it is more inconvenient. For me, giving up Facebook would have almost the same effect as giving up the telephone (for personal use).
Ajax File Upload With ASP.NET Using Valums’ Script

Pretty much anything can be considered as a "system," any aspect of it its "internal state," any aspect of it which can affect something else its "output," and any phenomenon that can affect it as "input" or "stimulus" (there is no need for any of these to have any higher "meaning"). The fundamental problem here is that any definition broad enough to encompass everything that can be considered "computation" is going to be too broad to say anything meaningful about the nature of the class of phenomena it describes.

Yes, asking what the nature of computation is requires a definition of computation in order to be a well-posed question, but the whole song and dance then reduces to asking about the nature of things that fit some chosen definition (and any definition suffices for playing that game).

If you want to learn anything substantial, you'll generally have to pick some particular model of computation to study. You could choose to study deterministic pushdown automata, and then you will learn about computation that fits in that model. Or you could study Markov algorithms and learn about computation that fits in that model. Or you could even study something like Turing machines augmented with halting oracles. For computers that fit a particular model, you can discover things like what they can and can't compute, how quickly they can compute various things, what it takes to convert a computation system defined in that model into another model, etc., and this will all follow from properties of the model you've chosen to study.

The only thing common to all models is that they have some way of mapping "input" to "output" via some change in "state." That is not specific enough to draw much further insight, so computation theory tends to talk about particular sets of models (e.g. "anything equivalent to a Turing machine").

Where do you get 1275? In any case, you can't consider all of this waste. Some of it is necessary (the connection headers, content-type, some of it is a performance improvement for a subset of clients (the link headers, etc.) and a small percent is waste (X-Recruiting etc.)
I do something very similar for my calendar, but it's kept in markdown and instead of deleting the done items I move them under a heading for the date completed(along with any notes about the item). While I'm not required to submit a timesheet for my employment, I find it nice to have a log of my actions.

The contacts file sounds interesting, I'll give that a try.

I think this will highlight differences among fields of education (?).

Programming is a very pragmatic field. Your ability to code is at its core judged by whether you can program something that works. Don't have a formal education? Whip up several interesting programs / websites on your own, and less people will care about your degree. In addition to that, it's becoming increasingly easy to learn the subject on your own.

Not many other fields are like that. Medicine for example. Sure, you can learn the names of the bones in your body, understand the use cases of different drugs in the market, but can you diagnose a patient? To learn that, you need access to training in real hospitals which are only given to students enrolled offline.

Same thing with biochemistry (needs access to labs and direct mentorship), law (access to courtrooms? or certification from proper boards). Many of these other disciplines are based on initial trust. It takes time for a biochemist or a lawyer until their work results in something. Having an actual (offline) degree places some kind of 'proxy' for the work result, until they actually appear.

I'm not that certain that they can be replaced / revolutionized by online classes. I'm all for revolutionizing education, but I don't think this new approach is able to revolutionize all fields of education.
I don't quite get it - how do other users access your files without having also shell access?

If they have shell access, why not simply use scp or rsync?
> It's hard enough to secure centralized systems using proprietary code behind firewalls managed by an army of experts. How can a decentralized system possibly avoid becoming a 0day distributed botnet?

I do not understand your concern.

Centralized systems are easier to crack, not harder. Proprietary code may or may not be easier to crack, but I'd lean towards easier. Distributed systems do not require you to not have firewalls. Distributed systems do not require you to not have experts managing them. Nodes of a distributed system do not have to obey the commands of other nodes or have a central control mechanism.

How would a decentralized system ever become a 0day botnet?
And you never addressed this? First, by politeness. If that doesn't work, by triangulation. (Talk to your boss and have him get it straightened out.) If that didn't work, defenestration.
