It's absolutely a data structure question. You have to know what functions are available to you from within the data structure.

For instance, in a singly linked list you only have the function "getNext()" and "getHead()"; in a doubly linked list, you have additionally have the function "getPrev()" and "getTail()". If parent asked me this question in an interview I'd probably jokingly say "well, you didn't specify doubly or singly, so I'd just call getTail and then getPrev until I was done!" And then I'd write a recursive function for a singly linked list because everyone likes recursion.

How could you possibly answer this question if you didn't know what a linked list was? If you never took a data structures class, you probably used "lists" but you have no idea what the bare bones construction is. Just using lists doesn't mean you know how to write one from scratch.
Under the FAQ for MITx:

If credentials are awarded, will they be awarded by MIT?
As online learning and assessment evolve and improve, online learners who demonstrate mastery of subjects could earn a certificate of completion, but any such credential would not be issued under the name MIT. Rather, MIT plans to create a not-for-profit body within the Institute that will offer certification for online learners of MIT coursework. That body will carry a distinct name to avoid confusion.

The true paradigm shift in education will happen when a student takes an "independent certification exam" related to a specific subject and is recognized as proficient regardless of how it was learned.

MITx is taking one more step in this direction.

The CollegeBoard's Advanced Placement Program does this now. High school students are allowed to take an AP exam whether they have taken an AP course or not. Their score on the exam (1 - 5) is a "recommendation" value that colleges agree to use to grant course credit.

It costs AP students $80 to take an exam. What would happen if MIT adopted this approach and charged $99 to "take the final?" Or consider the Machine Learning course at Stanford with 100,000 registrants. Were 1/3 of them to pay $99 to take the final, the benefit to Stanford would be north of $3.2M dollars! One course. They posted 20 new courses in November alone.

Compare that to what universities make by offering a residential class and the model gets clearer.
Raising awareness of any sort definitely helps for a bill that has yet to be voted on.

First, I think Nadam makes a great point.

But it also depends to a large degree what you want to do with your life. A good junior-to-mid grade Infantry officer for instance does not really need a deep knowledge of any one particular thing, but he needs to have a broad knowledge of many things and be able to move seemlessly between them and relate them to each other.

On the other hand, for a mathematician, even saying he wants a deep knowlede of math is far too broad, it would be better to say he wants to focus in on something like Chaos Theory. Even that might be too broad and many fine mathematicians spend their careers working on a handful of closely related problems in a very narrow sub-field of a field of mathematics.

This illustrates the folly of big government. The politicians in congress are not lacking intelligence, but are simply trying to do too much. It would be impossible for these 535 men and women to each have a thorough understanding of all the industries they attempt to regulate. Although the tech community is up in arms over SOPA right now, how many equally bad laws have been passed that affect other industries? The government is the entity that enables corporations to violate the rights of the people.
The paper is just describing common sense stuff: using eval() on user input and passing user input directly to a database.
In Sweden, it would be viewed as in the realm of fantasy. I don't know anyone who makes that much.
The only difference with other states of countries is that California got the budget crisis sooner, so it woke up first. It's better to have the crisis when you can still raise taxes (or cut spending).

Why can't they just use up/down vote on a post and determine these numbers automagically rather than have a user enter a value for each "circle"? I mean it seems analogous to the problem of spam filtering except that you have a weight function now instead of a binary 0/1.

I program. I am able to be social at a basic, perhaps proficient level. Frankly, I sometimes... no, often... find relating to other people, especially other non-nerds or non-programmers to be a real hassle, something I have to put effort into rather than just letting it flow.

With other nerds / programmers, it's easy: we share common interests. Yet where are the social venues for nerds and programmers? All in places unseen by more uh... "normal" (don't kill me plz) people. Maybe this is where the antisocial perception comes from.
This is precisely why they use reverse a linked list- it's common enough that everyone understands it, and if not, it can be quickly explained, and everyone understands that you 'just need to flip' the arrows, yet we get many people who don't get it.

Apple probably stands to benefit from SOPA if more people end up downloading music/movies from itunes. I think microsoft / amazon are in the same boat with their own downloading services.
It sort of works for me. Grey spaces where map tiles haven't loaded though, and I'm not sure why. Also you can't move around etc., so there isn't much to look at.

Still, nice concept.
I know, I get that. I'm a little frustrated by all the hysteria though. I know my comment sounded snarky and it's because of my frustration. The title of the post was very link-bait-y but the actual admin's comment made sense.

There are way too many submissions about SOPA that are repeats and the discussion is literally exactly the same. It's all about DNS workarounds or using OpenDNS then some guy says "no, use DownDNS" and it's just the same.

I know SOPA is awful but I think we can take a break from it for a minute and enjoy Christmas. There doesn't seem to be anything new to say about it so let's let it go for a sec, get away from the computer, and stop literally panicking.
We can only say that today, because we forgot about the other early third-person 3d games that had horrible camera movement.
Yes, but only if you have millions of unique visitors a month, and the niche is ludicrous like health/weight loss, personal finance, investing, insurance, etc. Once you gain traction, you can skip the middleman and go directly to the business, like Mint.com, Bankaholic, and InsuranceAgents.com.

If you're trying to sell low margin items like books, and even electronics, it's not sustainable at all. Not even close. Just do back of napkin math and you'll see...

The big problem with this, of course, is that word "educate" which the author encloses in quotes. The people who influence Congress "educate" representatives not with informative presentations but with money, and lots of it.

People know that copyright infringement is not lawful though, don't they. Generally, they just don't care.

Like speed limits on roads. People don't care enough to strictly abide by the law, or moralise their non-compliance in some other way - late at night, good conditions, law is silly, nobody around, etc..

Still there are some who buck the general trend. And I'm not only talking about indie games like Spelunky, but also (among all things!) several games for the oh-so-family-friendly Wii: Donkey Kong, Super Mario, and even Mario Kart on the higher difficulty settings.

This law seems to depend on the mailing list and the age/status of the language. I wonder how it went during the "Successor ML" conversations a while back?

Today, though, it seems as if almost every language conversation we have about Standard ML is a small set of implementers talking about whether, say, rule 64 is inconsistent in its handling of _where type_s and redundant tycons.
All I'm saying is:

1) Companies don't owe you any of this information as an interviewee. Sure, ask about the financial health of the company. But a balance sheet? Good luck.

2) You're going to get lied to in an interview about the health of the company. Do you really think a hiring manager is going to say "Yeah, we're throwing as many bodies as we can to finish this project, or else we're toast"? They want you to believe everything is fine from the day you start.

3) Even the financially secure companies hit the wall, get sued into oblivion, have their core product copied by Google, etc etc etc. You just don't know what will happen next.
You can share directly with one user on G+, either privately (just make them the only person you share with) or publicly (share with them, plus the "public" circle.) Either way, they'll receive a notification message that you've shared something with them, and it will also show up in their stream. It's a lot easier than, say, Twitter DMs, where they're a totally out-of-band message.
I don't know if it's a good news. Obviously, I don't know all the minute details of the situation but if I was him, I will not accept her back.

Female medical students not wishing to talk to a man about menstruation.

The fatalistic, egotistical and selfish attitude epitomised by women being unconcerned about losing their uterus. And of course, if you don't care about your own uterus, you're unlikely to care about litter, the environment, or pretty much anything.

(ps, as someone who has spent a lot of time in India and whose parenta are Indian, this fatalistic selfishness isn't a gender based issue. It is, however, one of the corrosive elements of Indian culture that worries me).

It looks very Rails-y with many sensible defaults (e.g. automatic CSRF for forms), but is quite a bit more lightweight. Making Redis a dependency is a smart choice; you need to store all session state, etc. outside of the process in order to cluster a Node app and take advantage of all cores.
With everything node.js provides, I can't understand why someone would use eval()... Specially with user input.

That's exactly what I did, I used to get the Piccadilly line from Kings Cross going south around the time the bomb went off. The trains on that line at that time are really packed, about 4 to 5 people per m2, I can only imagine what it must have been like down there. But, I was 10 mins late that day and couldn't get on the tube to connect at Kings Cross. People were running out of my normal station but I ignored that and walked down to Kings Cross thinking 'stupid Northern Line I'll get on there'. When I got to Kings Cross there were lots of people milling around and walking away from there, I think I asked someone and they said the station was closed. So I just got on a bus on Euston Rd and went to work as normal. I bumped into a colleague on the bus and she said she had been walking past an air vent outside Russell Sq station when there had been a huge inrush of air and a deep rumbling sound. I remember saying to her that it was probably just the power supply going out, maybe a transformer explosion or something (we had just been discussing mitigation of transformer explosions at work a few days before). Obviously, it was a weird day at work, nobody did anything really. It was too far to walk home, I ended up getting 5 different busses, partly because the service was all over the place and partly because I had to get off one because I thought someone looked suspicious. I grew up in London and the three lines and the bus route that got bombed were ones that I had used regularly all my life, I took it quite personally that they had attacked 'my places' in 'my city'.

What an inspiring story.

I grew up in a lower middle class family and I have two sisters. I know that my sisters and mom could not afford to use napkins because paying for the school fees was more important. As the story mentions, my sisters will take time off from school during those days.

His price of 12 rupees (25 cents) for 8 napkins is unbelievably cheap. That means a napkin costs 1.5 rupees which is less than a cup of tea you can buy at a road side stall in India. And I think 75%+ of his target market should be able to afford it.

BTW, you should visit the company's website, they have more details there:

The fatalistic, egotistical and selfish attitude epitomised by women

I wouldn't be so quick to judge. If you're a woman in India and a strange man asks you to try something weird that could potentially harm your body, I think you have every right to be suspicious of that person.

this fatalistic selfishness isn't a gender based issue. It is, however, one of the corrosive elements of Indian culture that worries me

I agree that Indians are incredibly selfish in certain ways, especially when you look at their actions through the lens of western cultural practices, but this is probably not a good example of that.

Yes. Building and effective REST client is actually really hard and if I want widespread use of my API, I'm not going to be handing out REST manifestos and expect everyone to read all 800 pages of it and retain everything. Otherwise, what's stopping developers from creating on an "easier" platform that uses GET site.com?action=delete&user_id=3 syntax? I can't assume anyone, not even devs, are smart enough to use an elegantly programmed system, so I provide the ability for RESTafarians OR infant PHP developers to use it.
I've been playing with the 3.2 kernels from the Ubuntu kernel PPA and there's a dramatic increase in battery life for me. I go from ~3.5 hours to ~6-6.5 on the same hardware.

If for some reason you don't know what a linked list is, you can always ask.

I think it's about admitting when you don't know something just as much as it's about being able to reason through the problem and give a correct answer.

All else equal, I'd much rather hire someone who didn't know what a linked list was, but asked and answered correctly, than someone who pretended to know and limped their way through the problem, even if they did eventually give a correct answer.
Linked lists are so fundamental, not knowing what they are is a big red flag. Anyone with even a modicum of curiosity about this field, college educated or not, should know what a linked list is, its complexity, and how it is structured.
Ive seen this phenemenon in person. I was the 2nd person on scene to a head on collision with two in critical condition. I was trying to open the doors and get the girl out by moving the seat back and testing for breathing and pulse. 5 minutes later I see a semicircle of people around the cars about 18 feet away with paralyzed people, 15 of them frozen. One lit up a cigarette. For 5 minutes.

I asked for crowbars or tools to dismantle the seat so the person could exit. No one moved, it was like a movie to them. I think it is a survival instinct that has atrophied to dysfunction. Playing dead, or waiting for a more experienced leader to emerge with instructions. I was unable to register myself as a leader to those paralyzed brains.
New Science Mnemonics (featuring a shark, Karl Marx, Zeppelins & Jesus)
I don't think it's a supply and demand problem. It's an ignorance problem and a financial problem. Media companies perceive piracy to be the cause of lost revenue above all others.

Step 1: Media companies need to understand the Internet. I honestly don't think they're actively trying to take freedoms from us. I think they just still don't "get" the web and haven't come up with a business model that takes advantage of it yet.

Step 2: once they "get it" they could use the tools they already have more effectively and attempt to use the web to their advantage without SOPA.

Put yourself in the shoes of the people at the media companies who are behind this for a minute. You're an old, probably conservative, wealthy person who is most likely hyper aware of anything going on that's entertainment related. To you it seems like theres far more of your company's content online than there should be and because you're in the media business you perceive the web to be an entertainment medium and nothing more. It dawns on you that since you're in control of content distributed through TV, the movies, and other conventional platforms (like DVD and BluRay) you should also be able to have control over this new entertainment medium too! It doesn't occur to you that the web is of, for, and by the people because the media has really never worked that way.

As hackers we're easily able to see the big picture and understand that the web isn't just one big On-Demand entertainment network. To us it's about entertainment as much as it is about communicating, working, sharing knowledge, education, art, and so on. But these people are viewing it from an outdated perspective.

I think that if we really want to make a change here we need to quit assuming that this is only about power and control for the sake of power and control. This isn't good vs. evil here, it's just two competing world views. If we understood why they believe they should be able to implement SOPA-like initiatives then we'd be better equipped to stop the problem at its root.
