Yes, Christensen in The Innovator's Solution talks about people buying products to get the jobs done that they want to do - we can consider a library and the internet as products, to get the job done of education.

He notes (p.94) that many companies tried to use the Internet to reshape the textbook industry, by supplying more content. But, he says, the job most students are really trying to get done "is pass their courses without having to read the textbook at all". These companies were trying to help students do something that they were trying not to do. He imagines a hypothetical "cram.com" would be more successful.

Most people (not all) find self-study extraordinarily hard - how many things have you, dear reader, set out to study but not completed? I think the only ones I have managed are when I'm using a textbook to help me achieve something specific - write some code, build a business, solve some problem. I wonder, is this really "study" or just "use of references"? e.g. Looking a word up in a dictionary is not really "study", to comprehensively master a topic.

It would be incredibly disruptive if someone found a way to make study - giving useful skills - enjoyable and easy. Gameplay seems the most favourable. I don't just mean things like SO-style badges, but like physical sports (games) teach motor-skills, eye-hand coordination, teamplay and strategy. It's like the "purpose" of play is learning. Note that even animals play (e.g. dogs and wolves have a "play bow", that indicates what follows in not a genuine attack).

An API for sharing stuff in the real world

RE: Nitrogen. I've started using an Erlang RESTful HTTP toolkit called Webmachine (http://webmachine.basho.com/) paired with an Erlang-based distributed key-value store called Riak (http://wiki.basho.com/) and I am very pleased with the ease of using these libraries. However, I can't offer you a comparison with other functional languages as I only have experience with Erlang.

I'm starting an extended and thorough series of technical articles regarding deploying Webmachine and Riak on Amazon Web Services on my personal website. Over the next week feel free to follow the articles and see what you think of Webmachine/Riak!
No problem, I added my email to my profile and emailed you.
DIY peripherals for Android
Aside from the predictable troubles the author experienced as an early adopter, I find it interesting that he has stumbled on one of the few motives web hosts and service providers might have to deploy services on native v6 (instead of relying 6-to-4 NAT): easier tracking and profiling of customers, by recording the MAC portion of their visitors v6 IP addresses.
Useful jQuery Tooltip Plugins That You Could Use On Your Web Projects
The other week a client asked me to make a div appear when hovering a link so I thought immediately at a jQuery tooltip. Sure, getting one that was appropriate to my needs was a little bit difficult and I found myself searching through a lot of them. At the end of the day I had a serious list of jQuery tooltips that I could download and even tutorials about how to create some hover effects that popular sites are using. I’m sharing this list with you and hope it will be as useful for you as it was for me.
I believe it exits are important but should not be the focus of a startup.

caus its the java-to-the-script doing this since 96'
peace to brendan eich for making it exist

it's an open-source license, of course we be frugal
peace to Lars Bak for v8 from Google

big ups to Ry Dahl for keeping it real
big ups to Joyent for paying all the bills

big ups to Marak, the new kid on the block
saying invest in nodejitsu, its a top pick stock!

( why? ) node.js allows for real-time sockets
over http, its socket.io and you cannot stop it!
Guerimo from learnboost blowing up like a rocket
just go to the github for the source (if you wanna cop it!)

need to install packages, use the module system
it was built by isaacs a man of knowledge and wisdom

npm install foo, now you rocking
require foo in any script you be dropping

ohh so you know a jQuery?
don't write write node and code
thats crazier then tim leary
because thats kinda scary if you don't know flow control
too many callbacks, its time to slow you roll

try Step by Tim Caswell
Chainsaw by Substack, it's just as swell
make your node code sane and not looking loopy
Node.js is the best so you better run Ruby.

(Run Ruby Run Ruby Run)
(Run Ruby Run Ruby Run)

so we throw our hands in the air like we don't just care
we wreck with Connect as our middle-ware
using the node-inspector to get up in there
we dance around on Github like Fred Astair, i swear
the Node wiki page is our second home
if it's not open-source yo we leave it alone
Node is the king and he can't be dethroned
Node is the code that's the hottest tech
if you don't have Node you better protect your neck

you see, node blurs the line of the server and client
battle hardened technologies and a community that is reliant
10 year javascript veterans that never threw in the towel
immense skill and experience like my friend paolo

it's javascript time, we own this shhhh
have a refreshing taste of caffeinated coffeescript

drip, drip, drip, thats the sound of OSS
from document cloud jeremery ashkanes is the best!

from nyc.js im making it clear yo
big ups to indexzero computer science hero
big ups to brian mitchell, and fotoverite
big ups to tmpvar, his capacity is very
intimidating, there is no debating
if you are a hater, node is what are you should be hating

The Atrix does this. However, it's not so trivial that it should be always expected just yet.
I found this project a few days ago while looking for a javascript logging framework. It looks slick, but I think I'll stick to my choice of using log4javascript due to it's support for logging to a server via AJAX -- this is a very important feature for a JS logging framework, as far as I am concerned.
You're so right. A bubble accepts exceptions. Google and Amazon survived the tech bubble, Paulson made lots of money with the 2008 crash, etc. Harvard will probably stay Harvard even with the bubble explodes. But the other 99% overprised colleges will be hurt badly.
I'm not saying that Google isn't doing this for business reasons - it just happens that in Google's case, they benefit more from all browsers being better than trying to make Chrome kill off other browsers.

I agree. It was a word choice between free and sale. I assumed free was a more effective title than sale for HN.

Note that when buying add a one-year subscription which will bring the total price to $108.
Having a ToS and Privacy Policy were a requirement before I could hook http://pagekite.net/ up with a payment processor - you can't take people's money unless there's a clear statement of what they are (and aren't) getting for their money. Refund policies, things like that.
So what? All you need is the initial email to work, nobody is going to notice fake whois that quickly. No person is going to show up at the address you list to verify that it's actually your address.

I've used fake whois records for a while and have never had any problems. I did make my main domain "real" a few years ago to avoid any problems, however.

These results were expected by neuroscientists. Different senses are encoded differently in the brain. So, the subjects were unable to link them at first. The surprising thing here is the speed the association between tactile and visual encodings happened, and the article makes that clear.

SPDY is always encrypted, so it would be more fair to compare it with HTTPS, where you can't do anything like that anyway.
He forgot one big one "he who names the price first, loses." While he was a very capable engineer, it took an experienced sales professional to extract real value for the software he was selling. Frankly, I'd have given her a HUGE bonus for getting the price she did. It's certainly worth the lesson she'd taught him.

This makes a lot of sense and echoes my experience. I'm lucky enough to study Engineering at one of the (if not the) top universities for Engineering in the UK. It also has a reputation for being one of the most theoretical in the country.

Right from day one, we have design orientated tasks, whether or not it's a structural design project linking in with our structures course, or designing an automated robot in a team from scratch (combining the mechanical, software and electrical courses). I think they've realised that people become Engineers because they want to see the fruits of their labour physically and not just in a purely mathematical sense.

I know without these design projects and frequent lectures from leaders in industry I would quickly lose sight of what I'm actually doing and would almost certainly have transferred course.
Steve Blank Part 1 of 5
iSteve is a horribly unimaginative title for Steve Jobs' biography. Frankly I thing the second half if the title is better. "The book of Jobs: The authorized biography of an American original."

Isn't this what Tapestry uses for client side error messaging? It's actually pretty useful for including in web-app frameworks: you can alert the developer to framework errors which might go un-noticed if just written to console.log. Of course you can disable in production.

On a side note, I've wondered how useful/practical server-side logging of js running client-side would be. For keeping track of what your users are doing, errors thrown etc.
Yes, because Thiel has better credentials so can be singled out. This is sorta the parent's point.
Ask HN: Single sign-on for external website on corporate intranet
I'd like to hear how people have solved single sign-on for SaaS websites, for integration in a company intranet.

The problem: Creating a seamless experience for the user (no extra login screen) while still having the external website authorize/authenticate the user.

On one hand, you could have a "company password", and the link to the external site posts company password + the specific user id. This is easy to set up (using their email as user id, and the internal cms includes that in the form submission) and doesn't require any additional services, just using the https connection that's already there.

On the other hand, you could do some AD integration. Not sure about the specific details here, but it could be a more solid, secure solution. More work would be required for this.
This would also provide for easier maintenance of user accounts (adding/removing users).

I'm sure there are several solutions in between. Which approach would you take if you were to integrate a SaaS website into a corporate intranet? Which solution would be best, with regards to 1) security and 2) ease of setting up and maintaining ?
Yet, correct me if I'm wrong, but Adams is advocating an entrepreneurship class. If all he's aiming for are the skills developed in entrepreneurship, why make it a class at all?
STEVE JOBS OFFICIAL BIOGRAPHY ARRIVES IN EARLY 2012
The book, ISTEVE: THE BOOK OF JOBS, is being penned by Walter Isaacson, famed biographer and the former CEO of CNN and managing editor of TIME. While very little is known about the contents of the book, Isaacson did manage to obtain unprecedented access to Apple, Steve Jobs and even Jobs’ family. Simon & Schuster will publish and distribute the book.
That's not a bad idea. Some suggestions/ideas:

- It would need to be asynchronous

- It would be nice to collect a log locally and send it centrally under specific circumstances (e.g. an error occurs send everything that has been logged so far)

- Using some kind of local storage option might be nice (e.g. the interface to SQLite that WebKit-based browsers have).
Followup on the star torn apart by a black hole: Hubble picture
Instead, it introduces them to lucrative career options (e.g., investment banking) available mainly to Ivy League grads. Given the massive salary differential compared to virtually anything else one could choose, most go that route.

Entry-level investment banking compensation is pretty low on an hourly basis-- definitely lower than entry-level technology. IBD is about the only six-figure job available out of college, but it's awful when you consider the nature of the work and most people leave the industry within a year, not capitalizing at all on the "exit options"
It's spring--which means students are thinking about internships & resumes.

You don't have to do it by the book--I built this originally for Seth back in '08, then realized I wanted to intern a few other places as well, so I sent them each a copy with a customized "Why do you want to work here?" speech bubble.

Landed me a summer externship with Seth, the month of August doing odd-jobs at TechStars, and November thru January working at TechCrunch.

Motion controls and button controls are not mutually exclusive. And buttons are essential for games that require more precise controls, in the same way that a physical keyboard is essential for writing long texts.

Thank you bubbles for allowing people to either have work or study. There's all this bubble talk, but when it comes down to it, if everyone really was just doing useful non-bubble stuff most of us in the first world wouldn't have anything to do. Our economists aren't ready for that.
FYI Ajax was a "feature" of IE5.

And I truly hope I can be as sloppy as Microsoft and build a software that reaches only 95% market share.

You need to remember that before you were born "stuff happened".
如何控制你的产品步调？
Murdoch’s News of the World prints phone-hacking apology
I've found the best way to get a discount at the Apple store is to know/befriend a specialist there. They're more than happy to kick a discount your way(after all they aren't paid on commission) if they know you. The $100 off my MacBook pro is proof. Sure it's only an 8% discount, but it sure beats paying full retail. Especially when all I needed to do was ask "can you hook me up on this?" and he did, no problem.
How can we make our products known by lots of people?

Yep, I'm pretty sure they're aware of Location, and they may be the best placed and biggest player right now. None of that is a guarantee for the future. The possibility is a new player can come along and understand Location in a way Facebook doesn't.
It's seems likely that Sun's IP licence was specifically written to stop Microsoft from doing its well documented embrace, extend, extinguish routine on ODF like they did to Sun's Java. Instead they just emrbraced, extended and extinguished the entire idea of a standard XML office format. Nice work.

Weirdly, Microsoft seem to have incompatibly forked their own OOXML format and are in no rush to fix that now that they've seen off the competitive threat posed by ISO standardisation of a competing format.
The last batch had 43 groups (see ycombinator.com).
It's quite silly that the author doesn't know this, but the feature he requests exists already and has existed for 10 years -- Privacy Extesions for SLAAC in IPv6 (RFC3041). It's even enabled by default on Windows.
It's entirely possible that this is the case, however the weight savings over such a small amount of Alu isn't really significant when compared to the thermal benefits of Alu for heat dissipation.

If they were to go with carbon cases, I could imagine it a lot more if these were parts that didn't require heat dissipation properties... the lids of MacBook Pros might be a good contender.

Even then would people like the look? One of the things in the carbon bicycle world is that there's little point in painting carbon as the paint increases the weight and you start to lose some of the benefit... on an computer device you'd lose more in that the thermal properties would be further degraded (and carbon isn't great at heat dissipation anyway).

And then there's shock absorption. Carbon is great for resisting knocks, but tens to have to be engineered with directional forces in mind. Hit it in a way that wasn't designed for and it becomes more like a car crumple zone.

I notice on the cited patent that the corners are not carbon fiber, this is usually because carbon fiber resists sharp angles, but could also allow the corners to be made of alternative materials to help alleviate the directional force problems mentioned above.

Anyhow... is interesting, but not sure we'll be seeing it on all cases soon.
It's only better if you -- by reading up on convention beforehand -- know which way an edge points; does decreasing thickness indicate an incident node, or the opposite? Not clear on its own.

Advanced Persistent Threats - Blame It On REO
It's nice, the only thing is, if your site's style sheet uses class names like "error", "debug" and so on, it will mess up the log window.

You have 2 options:
1 - modify your styles
2 - modify blackbird styles + code

I'll stick to console.log as well but a great tool nevertheless.
I get your point but there is one problem with that approach that has lead me to advise some clients to use such a filter. People like most of us reading here know quite well the evils and shortcommings of IE6, but by far the most people still using IE6 don't. I know it is hard to imagine for anyone here but I have friends whom I had to explain that some non-functional website was due to their prehistoric browser. Telling the public their browser is way too old is far better than presenting them a partially functional non-marked up website. It may annoy you and me, but we're not the public most webdesigners should care about.

Now to our own site disallowing IE7 while being targetted at web professionals. Pretty much no-one doing serious web development will be limited to IE6/7 - let alone use it as their primary browser. If you do and your employer is short-sighted enough to keep at IE6, you'll be part of a very very tiny minority which will most likely still not have access to PHP5.3 either.
I really like the gradient use on the edges. That, along with the taper, allows a reader to easily see the direction without having to follow it till it hits another node.
I kind of liked it. It was exciting.
Would be useful for me if it supported mobile browsers. Maybe bring up the logging GUI by doing a "secret" gesture?

Interesting, I feel for "trained" users who use directed graphs for work this is a valuable technique. But even the researchers admitted it is not obvious which way the flow goes. So I don't think it would work well for advertising or public presentations.

Japan: Powerful earthquake hits north-east
Here's what Piaw Na, a Xoogler, said about this piece-- it's worth quoting:

"When the Thiel Foundation came to a local startup incubator to pitch, it came under heavy fire. For one, a lot of their recruiting heavily targeted existing Ivy League/MIT/Caltech students. These were students who were going to do great regardless of whether or not they pursued traditional college paths.

In other words, if this is an attack on the traditional college path, Thiel's definitely sided with their filtering mechanisms.

One guy who was present said the following: "You guys denied admission to the program from the one candidate who was actually making money as an entrepreneur!"
Hmmm, interesting. I suppose even if that were true, the 'achilles heel' of such a system would be that they cannot openly admit their true intents. Thus they would be susceptible to innovative ideas (that weaken their position) when brought up in public debate.
No biggie. If you get a shot in your heart timely, you'd be fine.

Has someone tried it and was able to play something?

I tried it and iTunes lists it as a device but I cannot activate it in iTunes (if I select it, it immediately unselects itself). From the console output, I see that iTunes even does not try to connect to it (to TCP Port 5000).

I am currently on a Mac so I needed to do some porting (https://github.com/albertz/shairport/) but I think this shouldn't have an impact on the behavior I am getting.
Not true. I used the tc1100 tablet like I use the iPad now. All I did was buy an extra power cord and put it by the bed.
You're right, and I heard it's also enabled by default on OS X Lion. It's already enabled by default in the newer iOS builds.
