Strongly disagree, there is a vast array of articles covering a vast array of subjects on HN. Part of the joy of browsing it is finding articles on subjects I know little about and then doing some work to get my deficient knowledge up to scratch to gain the most from them. You sound like a university professor that insists you start from the basics in every essay so that anyone can read your work. If you want to read 1 music theory article with no reference to anything else then you need to start at music theory 101. BTW if you do want to understand what is going on here read something about building chords with thirds (and get to the point where you get that a third on a third is a 5th if everything is diatonic) - for the record i h ave had no formal training in music theory and have learnt everything from the internets from articles far worse and self contradictory than this. Now im going to go back to reading things about haskell and startups - things i know very little about btw and have to work to understand. Why would you want to read about things you already understand?

It's funny. I lobbied for years and years to designers to use fluid layouts (percentages instead of hard coded numbers). I have been met with a lot of condescending resistance. Fluid is bad because fixed layouts are good and I didn't know anything because I wasn't a web designer. The arguments didn't matter at all. The way it was done it was the way to do it, period.

Years passed by and now everyone is doing it, which is great.
Sure. That doesn't change the fact that storing passwords in a reversible way is a no-no. Advantages? Zero (I'm sure I'll get references to okcupid now..). Disadvantages: You are responsible for sensitive data and have lots of ways to mess it up.

And I didn't even touch problems that aren't related to outside attacks at all (You know, I don't even _want_ you or your customer support guy to be able to look at my password if you browse your customer database).

You do yourself a major disservice if you implicitly take responsibility for knowledge you shouldn't ever need in the first place.

What do you mean by secure encryption algorithms which are reversible? Encryption implies an operation in reverse order to exist, otherwise it is in essence, digesting.

It's always (almost) completely unnecessary to store encrypted passwords.

My Wish List for Education in 2012
Lets agree on the fact calculus requires logic, imagination and foundation.

I believe in order to teach effectively you must cover the foundations and review/revisit work regularly.

I was mindblown the first time I saw how the formula for an area of a circle was calculated (via sliced concentric circles rearranged to form a pythagorean triangle).

Practice without understanding is pointless. Perhaps start off with a foundational test every class for the first 2/3 weeks to get an understanding of what the students know.

If the foundations are set, then it's really a matter of studying course work (we study to remember things!) and practice and review.

Whitewashing (via practice) doesn't compensate for a lack of understanding.

We think in pictures, the best way to teach is to make everything memorable (usually by visualization).

In short, whenever you get a 'go slower', it's usually the case you actually are going to fast or there is a lack of understanding.

Assign less homework just screams of too much work or frustration that they understand how to get there, but sometimes no idea why it works.

Take courage, it takes faith to put your faith into your students. Discouraged? Encourage others - I'm sure your students could use encouraging too.

Best wishes

That's one of the main things I like about functional programming: a lot of logicy code smells can be factored away into reusable generic functions like, in this case, List.pick.

Likewise, engineers who have at least played with FP tend to be sensitive to code smell. In the absence of other, firmer data, I'm willing to loan some trust to a programmer with FP experience.
Technical Analysis: How to Determine Your Entry and Exit Points 101
It's never (almost) acceptable to be storing a users password in plaintext or encrypted. Time and time again we see this and I'm glad most of the time there is public outcry and the developers mostly respond with some variant of "We're using <buzzword> now!".

The day we move away from simple username password authentication as a whole is the day I can start feeling safe about my online accounts. Until that day there will always be the one crypto 'expert' attempting to dissuade the angry masses with his custom XES scheme which is super secure due to high amount of buzziness.

Hi!
I'm developer of this iPhone.
The reasons i've made it:
1. Challenge. I saw the icons in pure CSS and deside to make full iPhone with icons.
2. Demonstration of CSS3 posibilities (not all but many af them)
3. Inspiration. Many young developers write me and thanks me for inspire themto learn more, use more...

I titled it "..pure CSS3" because this iPhone is actually in pure CSS3, the JS part is for iPhone interaction. Without JS or with it - iPhone is anyway on pure CSS3.
Unwarranted paranoia.

The worst thing that can happen here is that somebody connects to your wifi. If someone can read your email and is in the vicinity to connect to your wifi, the least of your problems is that he or she does connect to your wifi.

Also, as pointed out by others, this doesn't mean it's stored in plain text. Any time you set a password it travels in plain text (typically - and hopefully - via a secure connection) and it arrives to their server in plain text. You are never sure they are immediately storing it properly encrypted in a DB. They can also be doing things like sending it in emails or storing it elsewhere. If you cannot trust your password to whoever is storing it you are basically f*ed. BTW, what do you think they might do whenever you enter the wrong password in the wrong site? (for instance, your email password).
Take an eCommerce system for instance, you want to open up complex shipping or discount calculations to your end users. A great way to to do this is to allow them to write a function that takes in known objects and returns a result. Say it takes in a cart/line_items and returns back a calculated amount. Obviously its a bit more complex then that, but it is a great way to expose some functionality without exposing the entire system.
I think RMS is difficult because he is not cooperative with people who don't share his views in their totality and because like many socially-awkward engineers, he has a penchant for making some really offensive and petty statements over what should simply be an ideological disagreement.

I agree with Stallman in many ways but I also have some important and major disagreements. I am sure that he would call me an enemy to free software, even though I regularly contribute to it, and that he would therefore consider my actions absolutely immoral and inexcusable. But I don't think it's immoral and inexcusable to charge money for things in a meaningful way (i.e., a way that actually generates money), at least not in the current context. I've read Stallman's arguments and don't find them particularly convincing.

I also don't believe that GNU is entitled to a prefix every time a complete system that uses the Linux kernel and GNU toolchain is mentioned.

So where does that leave me? As far as I can tell, Stallman would refuse to work with me, disavow any relationship with me, and consider me an immoral provocateur that harms free software no matter how much good I do for it in actuality (due to my disavowal of freedom 2 as an essential element in moral software).

That kind of hardcore, unyielding, exclusive ideology makes it really hard to get anywhere with people. You can't show someone the error of their ways if you refuse to associate or cooperate with them.

> "The provinces of Canada with higher ethnic diversity and immigration"

What kind of immigration? The USA has the unfortunate status of being home to a huge population of generally impoverished immigrants, thanks to its over-focus on family reunification and humanitarian immigration paths, the ease/prevalence of illegal immigration, and combined with a complete ignorance of skilled immigration.

This is the opposite of Canada, where the immigration policy has for decades strongly favored skilled immigrants - and have let them in in far greater numbers (and greater ease) than humanitarian immigrants. Similarly, Canada has for the past decade or so slowly shut the door and raised the bar on family reunification. It should also be no surprise that illegal immigration is a substantially smaller problem here than it is in the USA.

The somewhat inconvenient and blunt way to put it is: Canada has, for the most part, received a socially desirable demographic of immigrants, and the USA has not.

On top of this, America has to deal with the legacy of slavery - which has created a huge population that continues to be marginalized (despite advancements) to this day. You can't oppress and systematically destroy a population's chances of success for nearly 200 years in a row and then magically expect them to pick right back up a mere 4-5 decades later. This race dynamic drives a huge part of American demographics, and in Canada this issue may as well not exist.

The issue of race in the US is a labyrinthine beast that the vast majority of Canada could not even begin to imagine. And for that Canadians are lucky.

Looking at the most recent (at the moment, http://searchengineland.com/googles-jaw-dropping-sponsored-p...) comment it looks like this is part of a video advertising campaign by Unruly. Apparently (according to Unruly) the video is theirs, but the surrounding text is supplied by the blogger and should use nofollow links.
Garbage. The problem is not the transport-layer security. Transport-layer attacks are very difficult to implement. What is risky is what happens when someone gets access to the database and does "SELECT * FROM user". This is a very realistic threat, and with properly hashed passwords, gives an attacker no useful information. With plain-text passwords, though, they now have carte blanche to try the credentials at other sites, and steal someone's entire identities.

Yes, it's bad if you use the same password everywhere. Yes, it's bad if someone man-in-the-middles you. Yes, it's bad that arbitrary web users can run arbitrary database queries. But the point of robust engineering is to protect a system from many failures. If your passwords are stored in cleartext, your system is less safe overall than one that stores the passwords hashed. And because it's so easy to hash passwords, and because it's so damaging to your users to leak their password, it's generally considered Pretty Fucking Incompetent to keep passwords around in cleartext.
But that's because they use more manure over there.

2011: Looking Back and Learning
The worst thing that can happen here is that somebody connects to your wifi.

Unless a negligible amount of the 4 million users accidentally reused the password for other services as well. Which probably makes 3.9 million victims.

Also, as pointed out by others, this doesn't mean it's stored in plain text.

That does not matter much. If FON can extract it, an attacker can extract it as well, thus rendering it insecure.
I have also heard that tip plenty of times, but it's difficult to give links and references to real life conversations :).

I have exactly the opposite reaction. I can't stand the grid. I love cities I can get lost in. Streets that wind and wend are my favourite; ideally with a mix of canals and shortcuts. Wide, broad, straight streets are to my mind inhuman: built for grandeur and ego of despots in old cities, for cars in new ones. I like pedestrianized streets on a human scale, with organic layout and a mix of residential and retail. My home town of Galway, Ireland approaches the optimimum of small size that gives walkability and scale that gives diversity. Larger cities can be and often are formed like constellations of such smaller towns

There are tons of open source software that can easily be configured to do such a campaign with no programming. You could even preconfigure a distribution to minimize the work further.

The problem is then you end up with a bunch of cookie-cutter sites that look and feel sloppy and poorly optimized for the particular promotion. Also, if you happen to have a Louis C.K. size success you better have some know-how in your corner or your site will go down and your profits are flushed straight down the toilet.

Sorry to direct this at you since I realize it's not your point, but I'm also responding to prior assertions that Louis C.K. overpaid for his site. No, he paid for an extremely professional and impeccably thought-out user experience that operated flawlessly at a non-trivial scale and he got it. It didn't check all the web developer hipster snob boxes, but there's no denying it was extraordinarily successful in meeting its purpose. There's just no way to open-source that level of custom-tailored detail.

>"Free customers are higher maintenance than paying customers."

I would like to share my small experience with the freemium model. I have with a friend an online dominoes game where people can play for free but they have to be invited to play. Premium players are the ones who can create new games so in order to play free you need a premium user to start the game.

In my experience, all the author says is completely true. The free users require somehow more maintenance and they are by much the ones that complain more. However, in our case they are the ones that build the site. Without them, the site would be really desolate and premium users would be complaining about the lack of people to play. It would be indeed cheaper to maintain but I am completely sure that the income would be 80% lower.

I don't know if this experience would be helpful for the community here but I thought it would be interesting to share our case where free users are indeed troublesome but completely necessary.

Everyone here implies that passwords are stored in just another table of the database. There are other more sensible scenarios. For exmaple: authentication servers which talk to the front end using CHAP, well behind internal firewalls and with dedicated hardware which holds the private keys and encrypts/decrypts the data.

This has been discussed before. The ability to recover passwords has bussiness value, so at the end its a tradeoff between risk and money.

http://news.ycombinator.com/item?id=2917303

http://news.ycombinator.com/item?id=1249852

(in an interview I linked):

"Asked the key to success, (Finnish ambassador) Seppo Tunturi did not hesitate to answer: "The educator is highly appreciated by society. Young people see it as a profession with a future. "Statistics show that 10% of the top high school students choose this route. (Uruguayan university rector) Grünberg said this is a feature shared by other high quality educational systems, including South Korea, where teaching attracts 5% of the top high school graduates. "In other countries they would be brain surgeons or lawyers, but they are teachers or teachers in Finland," said the rector."

"In addition, training is very demanding. It takes a college degree (4 years) and an Masters in education (2 years). In 2010, more than 6,600 applicants competed for 660 seats to prepare as primary school teachers."

It's misleading to discuss matters of ethnic demographics in such terms as "diversity" and "immigration." The fact of the matter is, while immigrant and/or minority status can be a variable in its own right, it's usually just a proxy for effects that are specific to the minority and/or immigrant group in question.
