Scale. You won't be able to offer an alternative to the kindle without a huge budget; and without an alternative to the kindle all kindle users will keep either buying from amazon, or downloading books on the web.

Recording students' activities in their own homes seems unacceptably intrusive. If people think this is acceptable, would it also be OK for the software to sample ambient sound to insure that the student isn't watching TV or talking on their phone while they're supposed to be studying? Or how about requiring students to periodically perform some kind of dexterity test on their computer to prove that they aren't drunk or stoned or sleepy? Or maybe requiring them to see a psychiatrist if their studying profile fits the software's criteria for ADHD or depression?

At what point does student monitoring cross the line and become NSA-style surveillance?

The plan is to recover unused cycles, and ask the websites who power the platform to add a link to the opt in/out

It's because Apple did it first. Even in the PC days Apple behaved far worse than Microsoft, but somehow they army of fans that will defend any action from them.

This phenomena suggests it would be useful to have a mechanism to block the future use of original links when they're changed.
Yes, but Toyota just relocated their headquarters to Plano, TX, so it's hardly an "edges out" -- Toyota left.
This is missing the point completely. Stross doesn't claim amazon is a monopoly (well, other than in the title, but titles necessarily need to simplify to catch attention) - he calls them a monopsomy.

For a brief period I also worked at GE-Energy on their Smart Grid. This company has way too much bureaucracy to be effective in this space. The number of hoops you had to jump through to get a basic development environment set up were absurd. Many of the situations I ran into came right out of Dilbert land.

GE would be much better served by partnering with other companies and focusing on making hardware and machinery.

Nitpicking much?

As I wrote above, by making sure that I use a placeholder that does not appear in the data, I make sure that it does not cause the issues you describe. And if I was wrong with that assumption, I can at least minimize the effect by choosing a very unlikely sequence as placeholder.

I really see no issue here. How do you find valid grammars for fuzzy data in practice?
Not that I care about your sex life, but given the recent shooting rampage in Santa Barbara, your timing is in poor taste. To start, she's a "woman", not a "hot girl", and she has more to her than her looks. Many people - men and women - prefer a relationship over the simple goal of having sex.

Launching a company is easy. It requires only money. You don't have to change anything about yourself, especially if you have extra money.

Establishing a close relationship with someone else is much harder. You can get really hurt, and money or luck may have little to do with your success.

If you just want sex, there are any number of professionals willing to help out in exchange for a fair market rate. Any successful entrepreneur should be able to travel to a place where that business is legal.
"How can children learn about freedom when all their movements are scrutinized and analyzed all the time."

There's an implicit assumption there--consider that there is decent evidence that modern schooling (periods, bells, etc.) is a direct product of the need for factory shift workers.

There is no inherent good (from the government point of view--local, state, or federal) in teaching about freedom.
It would be interested to see how the market would change if Apple got involved in this. As cool as home automation tech is it's never taken off. Apple could potentially jump start the market - or it could be a total flop.

Another interesting side effect of this will be how it effects Apple's 'coolness'. The only people willing to spend the money on home automation tech are those who own homes or who don't plan on moving any time soon - i.e. not young people.
It is remarkable that top 4 IITs combined make up 5.2% of undergrad degrees of CS professors right after MIT 5.9% and ahead of Harvard at 3.1%. What is even more impressive is the fact that these four IITs admit around 140-150 students into the Computer Science program every year. It will be interesting to know how many undergrads graduate with CS/EE degrees from MIT and Harvard. Nehru's vision (India's first prime minister) for creating IITs was producing best technical minds for the development of new independent India, what happened instead was IITs attracted the best and brightest in India and became the number one exporter of top technical minds to USA. This brain-drain seemed to have slowed down a bit in the last decade.
It's extra work for website owners to build/test/maintain opt-out functionality. Have you considered offering a pre-built opt in/out widget which can be re-styled and integrated easily?

I think there may be more substance to the concept of equal weighting than there appears to be at first glance. I came across this paper via a blog post from Andrew Gelman. In that post he endorses the conclusions of a 2013 paper that reaches a similar seemingly-implausible conclusion: http://andrewgelman.com/2013/08/14/the-robust-beauty-of-impr.... That lead me to a post by John Cook on the same topic: http://www.johndcook.com/blog/2013/03/05/robustness-of-equal..., where this paper was mentioned in the comments.

This is terrible!

As .epub and .mobi come more into the fore, reading analytics has sneakily been introduced without any discussion or privacy debate.
On js-enabled epub readers spying on one's readers could be as simple as setting up a web analytics backend.
I know kindles also collect reader analytics[1].

We badly need free software like [2] to prevent this from happening under-the hood---any privacy-policy promises make by a vendor can't be trusted. Like Eben Moglen says, if they have the logs, there's nothing you can do.

Monitoring one's learning progress could be useful for adaptive learning content presentation
and positive reinforcement, e.g., "you learned 7 new things last week." Effort is a great metric!
I previously wrote [3] about a proposed learning metric similar to the stats reported by ''uptime''.
Also, like gyardley said below, knowing the reader's "knowledge state" can promote the "being in the flow because I'm learning new stuff at the edge of my knowledge horizon"-feeling, so it's definitely something readers would like. Surely all the customized-learning value provided by a centralized web application can be reproduced in js on the client side, no?

I wonder in what ways this could be different from being raised in a religious family and being taught since early years that you're always watched by God and your misbehaviour displeases Him. It does sound very similar.
Stross himself seems quite worried about Amazon declining pre-orders of his book. Not real orders once the book is out - just pre-orders. He obviously thinks he needs to be stocked by Amazon.

Does this mean Stross is an uninteresting writer? Or is he worrying about nothing?
That also has "higher level" problems. So adjunct history prof A convinced his students to spend, on average, 6 hours watching videos per week and adjunct prof B only motivated his kids to watch 2 hours, obviously the contract we'll renew is for A, heck we should put A on tenure track, what a motivational educator he is!

If the reason were collected and analyzed, it might be the case the prof A doesn't actually speak English or is utterly incompetent about the topic, so the kids are self teaching (true story from my youth!)

Now there may be anecdotal verbal end-of-semester survey results, but thats just meaningless prose from kids, but the number of hours of video watched is a number, therefore it is meaningful...
SnR?
The educator should ask, but they should also do the monitoring for one year. Then they can find out who the liars are and flag them for future professors.
The kind of debt mentioned in the article? No. In my opinion, of course.
The coursework has to be calibrated so that an average student can succeed. There will always be students who are smarter than average and can pick up the material much faster, or who have a personal interest in the material and have studied it on their own in the past (e.g., some kids actually like math or science or computers and study these topics extensively outside of school).

My 'biggest' technological nightmare in the latter years of high school was that regular schools would have enough online presence that snow days would become mandatory 'learn from home' days. Teachers would still hold classes, students would still have to attend (virtually), do work, etc.

Equal weights are also used in creating ensemble averages. It's always bothered me that the IPCC predictions for climate are done by averaging the results across models of highly varying quality, with each one weighted equally. Instinctively, I'd think you'd want to put greater trust in the 'better quality' models, but perhaps equal weighting is more defensible than it appears.

> time soon - i.e. not young people.

Doesn't that depend a lot on the specifics of the home automation
system?

Sure anything that requires a permanent installation is less likely to
be installed by anyone but the home owner, but can't you automate
a lot of things in your home without permanently installing anything?
One issue I see with this is that most home automation solutions (not all) run with a central hub, a server that talks to the other devices, and relays messages to/from them. This hub has an IP address that is reachable from home or away, so you can control it via your smartphone. The devices do not have individual IP addresses that are reachable. This would mean that to get a home automation system working, Apple would have to sell another device into the home. That's sometimes a hurdle for them. (Home automation server = new Apple TV??)

Yes, I know some home automation devices have the server built into every device (every plug, every camera, every light is a standalone "thing" in the Internet of Things), but this adds significantly to the cost. On the other hand, with some good software, it makes controlling everything without a central hub possible.
We changed the url from http://on.ft.com/1w8mTkI, which is the original source but behind a paywall.

I hate to do this, because HN strongly prefers original sources. Of course, people sometimes post a Google search url that one can click through to read the OP. But we can't make that the official URL for the post.

If anyone has a suggestion to solve this problem, please let us know.
Stuck on Mod_jk and AJP ? I feel your pain ; and I fled from it a long long time ago.

You don't need AJP with NGINX; this enables you to easily work with any J2EE app server or web server . I ran into issues with configuring glassfish with Apache and thus began using NGINX. Why bother with AJP ?

Yes setting up NGIX as a reverse proxy for Tomcat/ Glasshfish whatever is very simple. Setp a NGINX on your desktop and you will never have to connect to port 8080 ever again. Also it can serve static content while lettting your app server handle application urls.
All of these obvious questions are quite well addressed by the actual book in question, as would be expected from a serious and respected work, since its entire raison is to explain why this seemingly counterintuitive idea does in fact make sense and fits much evidence.

Here's a simple intuition pump to get you started: Do you think that you don't hear voices? Do you know about the concept of "internal monologue?"
I'm so happy that google is not officially recommending this. More than once that's been the one argument that worked with clients.
RapidSSL had the cheaper ones. Other than that the entire scheme is insecure so... I'm not sure if it makes any difference.
In every Python book I read they were recommending me to use Python 2.7 instead of 3.0. Shouldn't it be the role of educators to promote the latest version out there and work with it, so that by the time the new students get into a working environment they are already on the same page with what is required?
The thing you have to remember about the British press (and the majority of their readership) is, more than anything else, they love taking someone of notoriety down a peg. You can just hear the tuts and proclamations of "well this is why you don't stick your neck out!"
The author should realize that it's better for Python 3 to kill Python 2, before Go, Ruby or some other platform kills Python.

Currently most home automation products are geared towards family fathers who want to control every aspect of their families lives - control freaks. This is a market that does not scale.
Apple therefore has to present an entirely new perspective.
I have led several projects in this space and the one service that has been the most promising and was accepted by several family members was the anthropomorphization of the technology by presenting an addressable assistant that takes care of your home while you're away.

I've had helpful 'popups' on mobile sites that I couldn't close because the close button was perpetually out of screen, as they were not designed for the small screen. To my surprise, I've seen this on a number of big sites.

It baffles me that nobody ever noticed this bug, but on the other hand I can see how this would happen. The developers probably never noticed because they already had the cookie that prevents the popup from showing. Still...
Thanks, nice compilation. But is it me or is the first all-prefix-sums example wrong?
It will be interesting to see how much of this relies on the presence of existing hard wired systems, many of which are controllable over the network (e.g. Lutron, many security systems, etc). Writing to other peoples' APIs has not typically been Apple's strong suit. At the same time, wired-in infrastructure in a home is nothing like as disposable as the consumer technology Apple focuses on. There is no way I would want a closed system baked into my house. Hard-wired infrastructure is something you're stuck with for decades.

Relevant to me as I'm in the rough-in phase of a whole-home remodel project. I struggled a lot with what level of control to use, before settling on a minimal Lutron system for some areas of the house, comfortable in the knowledge that if I get tired of the Lutron interface, I can create my own & poke it over the network. I understand most people aren't interested in this level of control, but they might be concerned when their interface becomes dated in 5 years and can't be replaced due to an incompatibility with the hard-wired infrastructure. I see this as a downside of closed systems like Control4.

It is also my pet peeve. It is a big disadvantage, and I haven't ever needed the top bar (or wished it was there when there isn't one) so for me top bars are a feature with negative score.

The only lessons and areas that i ever remember from my youth, or any other time, has been when:
1) I was given the freedom to take my time and play around with the ideas for however long i wanted
2) Had no one breathing down my neck

Having to adopt such tools shows the failure of the education system in keeping students interested.

With the lack of freedom goes the willingness to explore and with that goes innovation.

I am feeling quite frightened for my kids right now.

Likeability is neither transitive nor uniform across a population. It's quite common for someone to be well-liked by some people and disliked by others for quite arbitrary reasons; it's also common for two people that you both like to dislike each other. Actually, highly successful people seem more likely to show this polarization, where they are liked by some and hated by others, simply because they are less shy about putting their personal opinions out there and people will have a wide variety of reactions to those opinions.
>I can easily imagine students rigging their reader with activity simulators.

If this had existed when I was in high school, I definitely would have spent hours writing scripts to automate interaction with the ebook, and more hours trying to reverse engineer their private API for phoning home with the 'engagement' data....before subsequently failing the test.

The PRAM model itself is interesting.

http://en.wikipedia.org/wiki/Parallel_Random_Access_Machine

> "Similar to the way in which the RAM model neglects practical issues, such as access time to cache memory versus main memory, the PRAM model neglects such issues as synchronization and communication, but provides any (problem-size-dependent) number of processors."
True. One thing that comes to mind is lighting. However how many people will spend £50 for a single bulb? [1] Maybe Apple has found a way to make it work. Then again maybe this is just a simple app with an API for developers to hook their stuff into and isn't going to be a 'flagship' feature of iOS 8 (kind of in a similar vein to iOS in the car - cool and useful but irrelevant to most people).
