Usually, you interview with a few people in sequence, that's why it can take so long.

In my experience, many technical interviewers are not very good at this interviewing thing; it isn't their core skill and on top of that they are human.

One of the early technical questions should answer the question: "Are you here by accident?" Google "fizzbuzz" for an example of this sort of question.

A poor but all too common flavor of interview question goes like this: "How would you write something that you would never write in real life but should have learned about in school?"

The interviewer looked it up before the interview so it's blindingly obvious to him. When you stumble trying to remember the Taylor series for the sine function they will think you are a bit slow. I always brush up on linked list and tree operations to prepare for this type of question. Try not to hold it against them - remember, the person asking them probably doesn't know what they are doing and all they may have been exposed to are other bad interviewers asking them this sort of question i.e. they know not what they do.

The good interviewer will try get you into the relaxed state you would be if you were actually working with them, and then ask you a technical question that's actually relevant to what they do day to day.

I thought lightly of all the arts classes I had to take in school and that my parents wanted me to take for "a well rounded education". Drawing, painting, ceramics, piano... It took me almost 10 years after high school to realize how useful it's been for me in so many random little ways. Everything from being able to craft some of the things I needed for my wedding (designing my ring to sewing a ring pillow and painting table numbers) to just everyday mundaneness when I'm meeting with a client and I can just draw out what they're thinking and get the point across easily. The piano especially useful because it's so relaxing and good for taking my mind off stress/pain better than painkillers.

Never in a million years as a kid would I have thought sitting in an art history class or 10+ years of playing a piano would come in as handy as all the obsessive studying I did of science, english, math and other classes. I'm so disappointed courses like that are disappearing (along with home ec - never had that, but my husband can't mend clothes or cook...) but so many people are struggling with basic math/language skills that I can understand why.
I don't understand how that wouldn't qualify as a Lisp? Does it matter what the level below is implemented out of?

Well... how to make this visible? If you imagine a tube that is just wide enough to contain a single marble and you fill that tube with marbles all the way then you can also image that if you push one new marble in on one end instantaneously another one will pop out the far end. It's almost as if the marble you put in came out the other end. So even though the electron (the marble) moved very slowly the signal propagated extremely fast.

Wireless hardware shares a chunk of the spectrum, much like cell phones share a chunk of the spectrum. So a node is not always transmitting the way a full-duplex ethernet connection is. Your packets wait for their slot to open up and then they are transmitted. The same happens on the way back. So the throughput can be extremely high but the latency can be murderous at the same time. And that's assuming the packet made it in one piece and did not have to be re-transmitted, in which case the lag will be even longer.

I hope that explains it clearly enough.

They're good on some things, bad on others. Generally the police are less militarized, and the criminal-justice system is somewhat less overgrown than in many other countries (lower % of the population in jail, much shorter typical sentences, etc.). However Scandinavia isn't really some kind of paradise, and the legal system is still zealous about pursuing quite some number of things I don't agree with.
And that, in a nutshell, is what's wrong with American math education. Too much focus on rote learning rather than actual understanding. What you're describing is an accounting course, not mathematics. Mathematics is about problem solving, not plugging numbers into a black box and blindly following a prescribed sequence of algorithmic steps. You do not want to just test whether students can follow a procedure; you want to test whether they actually know what they're doing when they're using it (even if you specify the procedure, e.g. Gaussian elimination).

This even applies to simple problems. See the comment by Aur Saraf responding to the original article: http://powersfulmath.wordpress.com/2014/04/30/who-or-what-br...
> Income mobility in the US hasn't changed.

That's a tremendously strong statement that I've never seen any factual support for, only opinion pieces with cherry-picked data from 'think-tanks'.

Rigorous looks have found precisely the opposite, for instance, from the Boston Fed's 40-year retrospective[1]:

> A variety of measures indicate that U.S. family income mobility has decreased over the 1969–2006 time span, and especially since the 1980s. Most overall relative mobility measures fell, on net, with mobility significantly lower in the 1995–2005 period than in the 1977–1987 period. Origin-specific measures also declined, with families starting in the poorest quintile less likely to make far moves (to the middle or higher quintiles) during the 10 years from 1995 to 2005 than within the 1977–1987 period.

> Similarly, absolute quintile mobility declined overall and for poor families after 1981–1991 (when real post-government income growth began to slow). Thus, families have become increasingly less likely to change rank or move out of their (relative or absolute) decile or quintile of origin, and when they move, to move less far; this appears to be the case overall and for those who start rich or poor.

WiFi attacks are not necessarily passive, ARP poisoning can redirect a victim's traffic to your machine at which point you can MITM to your hearts content. If you have trained your users to ignore the inevitable security warning (Grandma isn't going to check an SSL fingerprint) they are going to be operating under the false assumption that their communications are secure. For most people this is a worse scenario than the NSA having their data.

If you are talking about a thick client, with the appropriate checks built in, I'll agree that it's possibly more secure. Other than that, its only possibly more secure if you are the only user or you can eliminate the security warning (e.g. by distributing the certificate).

I'm skeptical that any US based company could get away with not rolling in the face of a subpoena/NSL so the protection provided by the service provider knowing they have been compromised is minimal IMO.

Because they are young and naive, or short-sighted, or believe that they will become one of those few platinum artists.

The last probably accounts for most of it. I forget the exact saying at the moment, but it is something about everyone in America believing that they are destined to be a rich person, and make decisions/vote in a way that would only be in their best interests if they were rich.

>Income mobility in the US hasn't changed.

This may or may not be true, but it's not important. What is important is that a society where there is a gap between those with education, wealth, and power and those without is (presumably) less stable than one in which everyone feels as if they are in the same boat.

Additionally, I would postulate that creating a class of people who are less educated and where both parents need to work 40 or more hours a week will not create ideal households for raising children (when looked at in aggregate). They also seem to have their children at younger ages, and higher divorce rates, which again, may not lead to desirable outcomes.
Likely - also, if true, basically the equivalent of putting a banner on their site saying “We don't value our users!”. Even a minimally competent management team should be able to look at the burn rate and make decisions more than a few days out.
It's something Snowden claims, but I don't see the justification for it if you actually read Snowden's email.

Snowden says his one (instead of multiple emails as he previously claimed) disproved this NSA claim:

"after extensive investigation, including interviews with his former NSA supervisors and co-workers, we have not found any evidence to support Mr. Snowden’s contention that he brought these matters to anyone’s attention."

But his one email made no such suggestion as bringing any legal matter whatsoever to anyone's attention. It asked whether an E.O. was really at the same level of statute law (it is, it is only the scope of effect that is different). Snowden's email didn't even suggest he had any complaints to make about NSA interpretation of law. If anything it reminded me more of the arguments made by "Freeman on the Land".

Snowden claims that other emails do exist though, with actual substantive complaints. But I'm not sure what to believe, if he actually seems to think this email of his represented a formal complaint, then who knows what was actually in his claimed email to the SID Office of Compliance?

He also doesn't mention who he sent his email regarding his EO 12333 question to. Was it this very email? Does he expect legal counsel to read minds too? And either way, his complaint was that the activity conducted under EO 12333 was "indefensible", not "illegal". But I don't know of any major organizations (private corporations or public agencies) that would deliberately take a harder route to undertake an activity they were authorized to do.
> Income mobility in the US hasn't changed. This is the strongest counterargument to complaints about income inequality leading to unfairness I am aware of.

It's not because it hasn't changed that it's fair and can't be improved.

Not trying to be a troll, but aren't these people essentially supporting theivery on a massive scale? I've never understood why so much of the Internet community thinks downloading software and/or movies that is meant to be paid for is ok.
I'd say what's killing laptop sales is older laptops. The software most people run on their laptops is not especially more demanding than it was say... five years ago. Even for hackers, a five year old Thinkpad or Macbook Pro with its RAM maxed out and an SSD is a perfectly viable computer.

We've seen plenty of innovation during that period in the laptop market. Entry level machines haven't changed a lot, but they cost half as much. At the high-end, much of the focus has been on size, weight and design. The Macbook Air, when it first came out in 2008 was pretty revolutionary. Then, a laptop was considered thin if it was under an inch thick. Now it's common to hear people protest that they couldn't possibly lug around anything so bulky.

Maybe these aren't the kinds of innovations you care about. I'm with you there, and a lot of the features I'd like to have aren't even available, but there has been considerable progress.
Is this what you mean?

Maybe I'm contrarian, cynical, and/or old, but I never fully understood the compulsion to advance an alternative mobile ecosystem in the form of iOS and Android -- at least not with the mission of eradicating OSX, Linux, Windows on laptops.

A tablet with a keyboard is a poor laptop replacement -- slow, limited, and in an awkward form factor.

Most "native apps" are CRUD apps that are better on mobile than web apps mainly just because mobile web browsers need to improve. (Admittedly possible big exception to that: Games.)

So if, after a couple years of experimenting, it turns out many people don't love tablets as laptop replacements, after all? I think -- that's fine. Experiment done. It didn't pan out. Let it go. Let's move the effort back to improving and innovating with "conventional" laptops and OSs, as well as trying things more inherently new like wearables or whatever.

I understand that each generation wants to reinvent all the wheels, but it seems like an unfortunate, wasteful diversion of resources.
I recommend a simple, fun solution that kids of all ages LOVE:

1. Download DrRacket http://racket-lang.org/download/
2. Show the kids cool functions from the 2htdp/image library, like (circle 10 'solid 'red)
3. Show them the animate function from the 2htdp/universe library
4. Leave them to their devices and instruct when they have questions

It won't be long before they want to make a game, and they'll need to learn all sorts of things about coordinates, shapes, colors, animations, and functions. Kids love functions. They'll have no idea how much math they're doing, yet at the end of the day they'll actually get it.

First, there was a complete denial, and now magically, an email manifests. That's the point you seem to be missing.
In the same line of thinking, I can remember most of my classes from high school. But that doesn't mean just being able to recall something made it a good use of my time.

For example, Spanish class. Now some people are fine with the language classes effectively just being a deep social studies curriculum around one culture where most of the time is spent on rote memorization for arbitrary reasons, but while I can remember my vocabulary, I can't speak real Spanish at all. But then again, I never did in class either. 5 years of Spanish, including two required semesters in college, and if I hear a Spanish conversation I'm completely lost. If they slow down I can translate the words in my brain bank and figure it out, but I never spoke the language.

In the same line of thinking, I read Shakespeare, Lord of the Flies, The Great Gatsby, Uncle Toms Cabin, etc and never actually got anything more than factual recall of the story plots to show for it.

Of course I remember the math, because I liked the math and specialized in the math and went into software in part due to the math. But the entirety of HN is deeply biased because almost anyone here is an intellectual who likes knowledge in general, so they didn't mind the English and Reading and Social Studies classes even if they didn't directly contribute to their future employability or character.

But most kids are not like that. It requires both luck and intellect to realize that you should make the most of the prison you are stuck in for your childhood. Many don't get lucky, and the mental synapses that would lead them to embrace the education system to extract value from it have a hostile reaction and abandon it.

And that doesn't mean they are dumb, it means they didn't get the right combination of random teachers to inspire them. If they could be inspired at all - it requires a specific brand of personality to be compelled into a repetitive environment and find value in it. Some just won't be able to no matter what.

None of it changes the fundamental flaw in modern education, which is the need to inspire children to learn the things that interest them most and learn about that. And to try to inspire them to find interest in all the things we routinely parrot from their textbooks and lectures onto tests for them to have a "placement" on. And if they don't? The parroting is rarely doing any good, and is only doing long term damage to the childs ability to reason and have a passion for learning. I don't think knowing the plot to Uncle Toms Cabin is worth that.
Again, the content of the email they produced isn't the point. That they spent much of a year denying any such emails existed is. Also, you're assuming their statement that this is the only email is true. By now, everthing they say, imply, or don't say must be suspect.

> They said no communications existed - and now suddenly they have one.

There's no contradiction at all.

He said he sent emails of a certain category. NSA still says they have no emails of that category—but they do have an email of a different sort, asking a procedural question.

NSA probably has lots of emails from Snowden on file, after all. What they've said (and continue to maintain) is that they don't have any reflecting a concern (edit: typo fix) over these programs. The email they released from him certainly doesn't show any concern. Seriously, read the actual question:

"I am not entirely certain, but this does not seem correct, as it seems to imply that Executive Orders have the same precedence as law."

This is hardly anything even approaching a hard charge of misconduct being done. Especially so given that the General Counsel announced that they agreed with Snowden's interpretation, "That said, you are correct that E.O.s cannot override a statute."

I see snooping as a lesser concern. For one thing the three letter agency snooping somewhere on the backbone can't even see the identity of the parties involved. They will typically see NATted IPs on both ends of some service provider. Once they decode the protocol they can get a little more information but at the end of the day the difference between knowing you established an SSL connection with respect to some static site and seeing the actual content of the page that you've viewed is IMO not a big difference.

The bigger deal is the confusion it creates and the assumptions a lot of the users of self signed certs (and certs in general) make about security.

Lastly I want to point out that if your certificate is signed by some external entity that doesn't prevent you from doing out-of-band management of your public key. As long as your private key is secret you never lose any security by having your cert signed by a third party. People can argue about how secure that signature is vs. those agencies who can force the third party to reveal their secret key but while that's an important consideration, until the government sells my banking information to somebody I mostly care about this at a principle level.

In this case of the toddler, the police are at least claiming that they used a battering ram on the door and it did not work. They claim that the door was blocked by the playpen.[1] As if that makes it ok.

It surprises me how no-knock can be legal. In some places, you cannot even respond with force. Or if you do, you cannot claim self-defense, as police get special privileges.

I don't even see how knock and notice is legal, as you have no timely way to authenticate someone claiming to be police. Why would an attacker simply not yell "police!" and scream orders at his victim? How would a victim possibly differentiate in this scenario?

A friend was just robbed in the middle of the night. His reaction was to yell at the intruders, claiming to have a gun. Had the intruders simply yelled back they were LE, my friend would have ceased resisting and voluntarily given into being tied up.
