You are right, of course, and I wasn't clear. Use Google, try to find any information on the guy or his theories outside of his fan wiki. If he was really "crucial in the development of radar", he can't be that obscure.

Great read. The linked article[1] on the Dunbar number is also very interesting, in case anyone missed it.

There was a good quote from someone wise about getting over the desire to stop interruptions by learning to deal smoothly with them, the argument being that any feelings of frustration with being interrupted was far more disruptive than many of the interruptions, it's not a skill that comes easily to me, but I can appreciate it's desirable nature!
> He was crucial in the development of radar, so he doesn’t seem to be a crackpot worthy of obscurity

That's a huge assumption. Plenty of people start smart and end up total wing-nuts.

Racket doesn't have math-oriented types, AFAIK, even in Typed Racket

As far as I know, it uses "machine-oriented" data representation when it can (sufficiently small integers, inexact numbers) and promotes to arbitrary-precision representation when it has to (larger integers, non-integer rationals). I don't know how much more OP expects out of "math-oriented" numbers than what's explicitly listed (no overflow, rational division).

There exists a matrix library, but it might be lacking some desired operations. I'm not sure what OP means by having "equation" as a type.
I'd be more interested by a HN Asia or something. I mean, political, technological issues in US and EU are different but not that much, after all. Japan, Korea, China, Singapore, India, etc... lots of stuff is happening there and nothing much comes to the surface.

Why, why is email mandatory to sign up???
I've been questioned pretty strongly the few times I flew to YYC (Calgary) from the US. All times it was for business, and I was pushed quite hard to admit that my work could have been done remotely from the US.

Granted, I am a developer, but my work couldn't have been done remotely - I had to be physically present. The CBP at the airport were generally unpleasant and surly.

Of course, there's also US Border Patrol in YYC's airport for the return back to the US, and I will say that the US border guards were pretty surly as well.

"genuine, present and sufficiently serious threat". Reading: they can stop anyone for any reason anytime at any place. EU is not much better than US. I hold Polish, German and US citizenships. Europe is actually worse because they think that they treat people better when in reality they are much worse it just doesn't get as much attention because it is not US.
Neither of those links contain credible information, which is one reason you are receiving downvotes.

The book on Amazon was interesting. I clicked through and had a look at the reviews. Startlingly, it appeared to be rated exceptionally well, with an average of four and a half stars over two hundred votes.

The first comment on the page was a glowing review from someone who claimed to be an electrical engineer with an understanding of science.

Really?

The reviews on Amazon used to be good. Now, it's difficult to trust them. I don't think you can explain the Book rating solely through the scientifically illiterate nodding along.

It doesn't even send a confirmation email, so it seems pretty redundant. Actually ... yes, it's required for password recovery. That seems to be its purpose. It seems like you can just put something fake in as long as you are confident you wont forget/lose your password.

Why doesn't it let me sign up without entering my email?

I think when I registered on HN, it didn't make email as mandatory!! Or is my memory deceiving me?

"I personally believe everyone has a right to move across arbitrary lines written on some map by wealthy people in the past few centuries."

That is false. Every country has the right to determine who can enter its borders.
right!
I live in India, and though I do tend to get updates about local startups irregularly, I am still not aware of any good HN like site which keeps me up to date with all the latest activities in Indian startup world.
Interesting. I think there's definitely demand for services like this.

We have been working on a community for entrepreneurs and startups in the UK (in addition to our information website), lion.co.uk/community, we're still in the phase of optimizing things.

We've found that there's many entrepreneur and startup websites but gaining critical mass to make a useful community is another thing.

We should probably work together but then again, as others have mentioned, there's different requirements for different people. Founders of businesses other than technology and hackers for example might not have reason to collaborate.

That said, the more resources there are for business founders the better; especially in Europe right now.
I don't claim that normal people can't or won't be conditioned to develop hostility in us vs them scenarios.

I also don't claim that being in the military doesn't change people. Everything changes people, and the change in the military can be profound; in my opinion that change will most often be positive. I am biased, being ex-Navy.

What I'm saying is that the military doesn't produce assholes to the extent that you can reliably explain that behavior as a result of having been in the military. They're individuals.
That's really awesome, I will definitely use this. It would be even cooler if I could style it a little bit.
Recently I deployed a new design for my web app that I thought was much better than the previous.

A few of my users complained and I decided to rollback the changes. Nobody has complained about the rollback but I still believe the new design was better.

I find it hard to know how to decide when to push further against the community sentiment. Facebook has done that countless times and it has worked for them.

I guess this is where the founder's vision comes into play.

How do you decide what to keep and what to ignore?
Maybe it will do things in new ways that are better than HN. Maybe it will eventually become more International like HN is? Choice and variety are a good thing. You've got to differentiate yourself somehow when you're starting out.

It is pretty funny, but the ads makes it seem as if there are real people snooping into your emails when it's actually just some bots that are trying to serve you ads (which is inevitable) that might relate to you, isn't that better than just having random stupid ads show up on your page?

I appreciate it when Gmail tells me that I'm missing the attachements or when it asks me to add the event written in text in the email to my calendar.

I'm not saying Google is not evil, but it's hypocritical of Microsoft to say this while they're actually doing the same thing reading people Facebook statuses on bing and so on.
I'm British and I think this is a great idea. I'm interested to read about the startup scene in Europe and the UK.

I do think that we should be trying to move away from the 'hacker' label. People are never going to understand that 'hackers' can be good -- See that AP Press article. And really, our definition is the less popular one, and therefore less correct, and it is we who should change our wording.
Thanks for checking out the code. I am aware that JavaScript's "bad parts" are used throughout. This is of course a prototype built rather quickly. In the end all of this will be done using backbone.js (and will be much faster). If I approached this pedantically, it would have taken me much longer.
This post probably resonates with a lot of developers who have been working at the same company for more than a year or two. Working at a one startup after the next and moving on quickly, I don't think you get an appreciation for the maintenance "grind" that this article so accurately describes.

My experience is not nearly so dire as this article, but aspects of it do come up at times. I'll have to check out the suggested reading.
Tight integration between a mobile phone and a desktop OS is IMO a misfeature.

Based on your two examples it seems as if you feel this way because you've only experienced light integration or poor integration, and don't have the imagination to see past that.

If Microsoft can make it work, and offer something polished in the process then it could be something special. Remember they're counting the "desktop OS" of Windows as their tablet OS as well now. There exists untold numbers of opportunities for nice little integrations done well.

Consider too that for most people in the developing world, a mobile phone is the only "computer" they will own. Requiring integration with a desktop PC effectively cuts Apple and Microsoft off from a market of billions of people.

That's why you don't make it mandatory like you're suggesting.
Why do you think politicians like it the way it is? They don't win anything. I think the don't understand what going on.
Many europeans feel like outsiders at HN. Indeed HN content is localized to some extent.
Perhaps that's the reason why there's no HN meetups near by your location?
It's an interesting point he makes, but you're right, he has no numbers to back it up. Doesn't anyone keep data startups and acquisitions?
Yes, very soon.
You're completely right on the math. I had math-oriented types wrong; I assumed that the author wanted the ability to say, "This type is restricted to values defined by this set," which he didn't. Even if he did, I see that Typed Racket actually does support such types, which is awesome. So I'm completely wrong.

Whether e.g. #hash((key . value) (key . value)) counts as a literal hash syntax is interesting. If you want to argue it does, then I'll argue that C does, too, since I can trivially #define my way there through C99 struct assignments and a function that constructs a hash off an array of those structs, or that C# does because I can use an initializer (e.g., "new Dictionary<string, string> {{"Foo", "Bar"}, {"Baz", "Quux"}}"). Literal hashtables and vectors, to me, means something that's visually apart from base syntax forms, specifically so that it stands out to the coder. By this standard, Python, Ruby, Smalltalk, and Clojure would qualify, while Racket, Io, and C# would not. Whether that matters to you depends on what you want.
Have a look at the "gob" package for serializer and deserializer support for Go types.

As for the syntax-related points, Go offers quite a bit. There's the goyacc tool, the scanner package, the template package (think quasiquote), and a bunch of packages for processing Go code: go/ast, go/scanner, go/parser, go/printer, go/build, go/doc, etc.

For math-oriented numbers, there's the "big" package. Many languages make such numerics much more convenient but you can get pretty far with little effort using just the "big" package.
You are completely wrong. http://finance.yahoo.com/q/is?s=MSFT+Income+Statement&an...

Every government, legitimate or not, has the power to decree who may or may not enter the country.

There's a huge difference between a power and a right.

On Washington Post: Facebook IPO: A look at what we learned from the filings
For GNU tar these days that's true, unless you can be sure $TAPE is in its environment. Historically, tar defaulted to a tape device, e.g. /dev/mt0, and you still find vestiges of that, e.g. OpenBSD defaults to /dev/rst0.

IOW, specify "f -". :-)
I'm an American, I've lived several major cities (so I'm not blinded by a specific localized culture), and calling people "guy" as a generic pronoun doesn't strike me as a universal Americanism. Where it is used, it's just as a greeting:

"Hey, guy..." or "Hey, dude..." or "Hey, man...". I prefer just "Hey" or "Hi" to get someone's attention. "Mister" and "ol(d|') guy" seem anacronistic to me. (I was born after Vietnam if that helps.) "Mate", "chap", etc. are the same idea, but originate in British (or colonial British) culture.

Those attention-getting pronouns are frowned upon in formal or "civilized" (upper-class or upper-middle-class) communication, I suppose because it's considered informal or rude to try to grab someone's attention that way. However, in everyday vulgar (as in not-formal) speech, I don't consider any of them to be insulting. There are other culture-specific race-specific and gender-specific pronouns which can be very insulting, to the point of getting you killed when used in the wrong situation, but can also be okay depending on who you are and who you're talking to.

When talking to cops, border guards, or any agent of the executive branch who has the power to ruin your day, I would always use "sir" or "ma'am".
Rota's 1913 French patent application for this device can be found here: https://docs.google.com/open?id=0BwUohGCPTAlANTg5NTg2ODQtMzF...

It's in French of course, but it contains a fairly clear description of the device and its construction, although it doesn't mention the voltages needed. The implication from the text is that a DC voltage would be provided (it specifies the +ve and -ve plates).

It appears that it consists of a pair of capacitors (spaced charged plates) placed inside a magnetic field generated by some electromagnets (it looks like there are a total of 8 electromagnets around the capacitor). The whole thing is cased in a metal shielding.

So, it would seem quite buildable although there's no data on the size or voltages involved.
Ask HN: Advice wanted in hiring and/or working with a web designer
I have an acquaintance who is launching a web site and wants to connect with a web designer to help with the visual, and possibly the "conversion" aspects of the site. The usual "Help Wanted" postings are often met with derision by hackers, so what advice would you give to someone looking for a web designer to help them?

Often the advice given is "pay properly", but I suspect there's not a lot of money available in this case. I don't know about equity, but do I know that hackers will, on occasion, hack deals as well, so all thoughts welcome.
That was totally missing in the article. It'd be really interesting to see the difference between display advertising and ads in search results.
Right, the difference became more pronounced, but that doesn't really tell me what I as a planner would want to know. Consider two possible explanations.

(1) Some workers who had previously produced defect-free code started producing code with defects as the noise level increased.

(2) Some workers who had always produced code with defects started complaining about the noise as well.

In one of these cases, keeping noise levels down would make a difference. In the other it would not, and the numbers as given don't tell us which scenario applies. They also don't tell us the relative numbers of noise-tolerant vs. noise-intolerant programmers. If those affected by noise are a small minority, then an employer might make the choice to maximize office density and let those affected "select themselves out" by going elsewhere. OTOH, if just about all programmers are affected, that's not much of an option. If the authors reported that the number of programmers producing defect-free code went from X% at 20dB to Y% at 50dB to Z% at 80dB, then that would be much more useful. Similarly, these studies don't seem to measure time to task completion or ability to complete multiple tasks per day, which would be other factors in such decisions.

BTW, this is more than a theoretical issue for me. I'm working at home today because the noise level in my office - due to high density and low partitions - has become utterly intolerable. Just about everyone wears headphones all day, presumably because they feel likewise. I'm a bit disappointed that one of the most-cited studies in this area does not really support any useful conclusions that can be brought to management.

6 Tips For Introverted Travelers
The number one reason for me would be because lots of the things covered on HN tend to be US focused to the point that people forget anywhere else exists. I'm tired of articles praising some service provider or payment processor only to find they are US-only and may support the EU in 'the future'. I'm tired of rants about carrier practices that only affect the US as if it is universal. I'd like to see a site where there is an actual consciousness that not everyone is living in the United States of America.

"Surely this is exactly the opposite of what Martin Luther King wanted when he asked us to judge people not by the color of their skin, but by the content of their character."

Putting aside the ridiculousness of that statement, given that it came from a black guy who had sex with White girls just because he saw them as trophies, the real reason an asian is likely to be rejected from Harvard is exactly due to their character. In general, asians don't donate. Harvard has to care about such secondary issues, which don't make it into the news. If Hsu really cared to know the truth, he would analyze the racial makeup of the graduates who donate to Harvard. I don't have those numbers, but my best guess is that Whites rank as the highest financial contributors, and that they do so, by far.

I don't think this will necessarily gain traction without a huge push to build a community.

It would be cool if a system like subreddits was added to Hacker News where it makes sense (e.g. Europe).
This theory seems to assume that the startup founders have no say in being "talent acquired" by the big corporation.

Being angry at Apple or Twitter for buying a company and shutting down their operations seems misplaced - why not be angry at the founders that agreed to do this?
Hashing a salted password is definitely the way to go - and of course if your hash algorithm is worth anything you should not be able to "unhash" it again.

It would, I suppose, be possible to salt and encrypt a password before storing it and thus be able to retrieve the original but you would have to be very sure that no 3rd party could get hold of your encryption key.

I listen to music all day every day when working (from home) and feel it helps me to be more productive, mainly because I'm relaxed and enjoying it, which in turn contributes to me enjoying my work. However, if my other half comes home and starts having a phone conversation–at a significantly lower volume in another room–the muffled voice really distracts me.

I certainly feel there is a correlation between _tolerance_ and performance.
A shorter version of the same thing:

You have to figure out what feedback is meaningful and what feedback is merely change aversion. If the users have a valid point, then maybe consider reverting. If you believe it's just change aversion then you have to stick to your guns for the greater good.

Just like you said with Facebook, people will gripe about every change. But they gradually will appreciate the improvements as they get used to them.

Does it matter? The people who read Hacker News or Hackful Europe will understand the meaning.
I agree. I am a dual-citizen of Canada and the U.S., and I hate travelling to the U.S. because > 50% of my interactions with the U.S. border folks are suspicious of me because I'm a dual citizen. There is something wrong with a system that is set up to assume that people are lying to you when in reality they may be confused.

IMO, better people training is required—but that requires spending money on soft-skill stuff that the U.S. doesn't want to spend on either CBP or TSA agents.

The absolute single biggest problem with the way CBP works (especially for non-citizens) is that a CBP agent with a bad attitude can decide to reject your entry for no reason whatsoever and no right of appeal. (The second problem, at least at Toronto Pearson, is that some of these folks apparently hate working in Canada. If you hate it, get a fucking transfer. You're a guest in Canada, and it's a great place to live. Stop being a sourpuss because your bad attitude is making it worse for all of the people you interact with, and you're a representative for the U.S. Do you really want to give a negative impression of the U.S. based on your attitude?)
