I assume stupidity on the part of Amazon.

Oh I'm almost certain that this is stupidity, and not malice. (Why would amazon shut down an account of some regular person?)

However, the big problem is that "all the books you own" should be dependent on a massive company never acting stupid. The problem isn't stupidity/malice, the problem is that stupidity can have such a massive massive effect.

Never ever buy e-books from Amazon, only physical books and things. Especially because all e-stuff on your Amazon account can be permanently deleted without any option to restore (except to buy it again).

I agree on the DRM content though.. The problem is that most people will probably not.

Beautiful data visualization :)
Laws trump contracts. You cannot sign away what the law says happened. It's just a matter of convincing a judge that you bought the book. They Amazon's T&Cs are irrelevant.
Well if you were planning on having an instance run for a long time, and it's a CPU bound process, then it would definitely be worth experimenting with a roulette system.

Some people already do this for EBS disk I/O issues, you fire up an instance, run some sample benchmarks, and kill the instance if it's a problematic one.

I have a Kindle and never read nor use any DRM books. You don't need to use Amazon's software or service or anything. You can convert files into .mobi format using open source tools and use a programme like Calibre or just put the files in the "documents" folder of the Kindle to load them.

Using a Kindle without DRM is very possible.

Waterstones used to use Amazon to sell books (presumably they couldn't make any money any other way). Not sure if they still do.

http://www.abebooks.co.uk/ is pretty good, particularly for difficult to find and second hand books. I've found more and more recently that play.com does almost as well as (and often better than) Amazon in terms of price, although I don't know much about their business tactics.
"When there are less than 200 examples, the training set and validation set have the same size. Otherwise, the training set is composed of 100 examples and the other examples constitute the validation set."

Why divide the data into sets like that? Assuming the sample data is representative, wouldn't it be better to use much more for training, say 90% with 10% for validation?
Well that depends. If a court decides that you own files you purchase online like this, then you own it.
What I suggest you is to not learn a language, but instead learn to code. That is the hard part. Learning how to say something is easy, learning what to say, is hard. Each language has it's features, use case, pros and cons. But when you know what you want to achieve, learning a new language is something relatively easy. If you choose to learn something and stick with it you will only find the jobs for that. If you learn how to think, a language will no longer be a problem.

This is not an easy thing to do considering you are a beginner. But I strongly suggest you to go for it. Lear something from python or c# or php and then mix it. PHP is good because you can then mix it with html javascript & css to create a complete set of web skills. C# might be good to learn about classes types and other things. Each language has it perks. Learn a mindset and you will unlock them all.

I also suggest you to spend more time coding than reading books. Avoid videos, huge waste of time. Doing things, making mistakes and trying to understand how things works will teach you faster than anything.

Good luck.

Myers-Briggs as a psychological test is basically useless. MBTI indicates bimodal distributions of the attributes (people are either introverts or extroverts), when they are more like a normal distribution.

Gardner also lacks any real credibility, unless you throw out everything except "different people can be good at different things". It's good to encourage students to study a range of stuff (art, music and interpersonal stuff, not just math and english), but that's not really what Gardner is about. Students who are good at music aren't likely to learn math better if you sing it (OK, maybe I'm exaggerating).

Individualization isn't a great method. It's hard to do, and has a fairly small impact on student outcomes. Most students work best if you show them a diagram, explain everything, give them a chance to try it themselves, and demonstrate things in a number of ways. It's not about "different strokes for different folks"; most students like a bit of variety.

The reason many students struggle is because they lack the right foundations. They didn't learn it last year (for whatever reason) so they struggle this year and can't catch up. This is much more common than students simply not having the right talents.

I'm not from the US, but Australia. From what I can tell, the US varies from state to state. The problems with the US aren't really related to pedagogy, but social issues (large black / hispanic communities going to black / hispanic schools, where everyone is trapped in the poverty cycle) and the way their standardized testing dominates everything. Every year the teacher is mostly concerned about the students passing the end of year test, at all costs, and the end of year tests seem to be badly designed.

My (unique) passwords are always more than 25 characters, and it really irks me when websites place maximum limits on the length.

Worse still is when they don't even tell you about the maximum limit, so you paste your 25+ character password in, fire the registration form off thinking everything is fine, only to find they'd only taken the first 10/15/20 characters and the full length password you gave them doesn't work.

Tell HN: How to see a web page that just got crushed by HN traffic
This might be obvious to some, but to others it might be of benefit, especially with the number of blogs that go down due to HN visitations.

1. Go to google, type in site: followed by the full url of the page you're trying to visit. If google has indexed the page, then it will appear in the search results.

2. Hover over the link and you will see two arrows appear like this >>

3. Hover over the arrows and you will see a cached image of the web page appear. Click on the word "cached" beside the web page's url and you will see google's cached copy of the web page before it disappeared.

You can just set your browser to not accept cookies. That in itself doesn't require a cookie.

Although I'm not sure why you opt out of cookies. They enable sites to keep larger files cached for longer, so that the sites you visit frequently load quicker. They help Google personalise the ads you do see, so that you don't get crap about Viagra pills, instead you get something that actually be of use to you. And most importantly they enable business to identify users coming to their site and optimise the way their website works to be most effective.

The opt-out culture that is popping up is damaging business by not letting them do their jobs efficiently, or rather preventing them from gathering information of traffic patterns which lead to site improvements. Cookies aren't malicious 99% of the time, and when they are malicious it's because you're on a dodgy site to start with. And that's what private browsing is for, if you really must visit the darker pits of the internet.

The internet you see today, the many positive aspects of it, and the rate at which it has changed from crappy geocities sites is owed largely to the information web designers have been able to glean from cookie data.
A Web Designer’s Introduction to A/B Testing
What is the minimum viable PaaS?
Severity isn't that low. If you hand out a USB stick to a friend and they run a .exe on it, you could surely trigger this exploit invisibly. It's probably not a broad vector attack, but surely would fit very well into a spearphishing scenario. Hand this to a less-than-savvy user and either auto-run via .inf (on older OSes) or dupe them into running some arbitrary binary to "unencrypt the volume" or something they wouldn't understand.

Many newer USB sticks even have preloaded binaries for the supporting software (SanDisk volume utilities come to mind) - this would be a perfectly innocuous location to load this sort of attack.
AMD to use 64-bit ARM cores in 2014
Even though it's almost certainly possible and even practically achievable to compress the required data into the 1MB of space, doing so without using more than 1MB even in temporaries might be impossible. (To get this close to the bound you'll need to use "excess" entropy from one bitpattern to save space in the next; i.e. a delta # doesn't straightforwardly correspond to a bit pattern, but instead depends on context.) Clearly it would be hard, as you say.

An argument that you need context info: if you don't use context info, each bit pattern needs to be rounded up to the nearest number of whole bits. That waste's about N/2 bits. According to my calculations, that would raise the bound from 0.96MiB to 1.02MiB, i.e. too much.

But really, it's even worse. Let's assume you can indeed define such a compression and you manage to use the context sufficiently to avoid wasting too many bits. Further, you manage to do so without using much temporary space at all.

That means you'll need to be updating your sorted list in place. Each update is likely to be a non-trivial task, since you need to find the place to update (with variable-width encoding and no space for luxuries like an index, that's probably a linear scan), and you need to take into account some amount of context - and then, because you've changed some data, recode possibly unbounded amounts (so N) of following context. That makes this sorting algorithm quadratic; and it'll have a high scaling factor too since the operations we're counting here aren't cheap: we're not moving bits around, we're decoding and recoding them all the time in a context-sensitive way and that means doing lots and lots of branches.

Assuming the 1MB limit is reasonably inspired because the chip neads to be tiny, you're probably not dealing with the fastest chip in the world. As an estimate, I'd guess this algorithm (if we could make it) would be about 1000000 times slower than a normal sort (assuming a 13 times higher constant factor), and you'd be running it on something very very slow. On a modern processor, a plain sort takes about 75ms, making this thing 75 ks, or approximately 1 day. On that very limited 1MB proc...

So even you manage to pull it off (very hard), it's almost certainly going to be very slow.
Well, the same thing could happen with physical books and a moving company acting stupid - may even be more likely. The difference is that you can sue them for damages in that case
I know it's not the best attitude, but if this ever happened to me I would simply pirate all the books I'd purchased from amazon, side load them onto my kindle and keep reading guilt free.

A part of me would like to dump amazon due to stories like this, but at the end of the day the whole set up is just too convenient (I can find, 'buy', and start reading a book in less than a minute directly from my kindle)

The worst part is that attitudes like mine are probably a big part of the reason Amazon will continue to get away with this. The even worse part is that I just don't care enough to do anything about it.

I wonder how many others there are like me who should know better, but enjoy the convenience too much?
AbeBooks is actually owned by Amazon now.
Can git work with subtrees yet?
And, how, pray tell, will you convince the judge of that? You didn't purchase a book, as the T&C's make clear - the contents of which you agreed to by entering into the said agreement.

You paid applicable fees to enter into an agreement to view digital content. Nothing more. There was no purchase of a book.

Where's your evidence to the contrary?
Some context is implied in all communication. Most people who read HN do, and more to the point, they have an Internet connection and loosing that would alienate them from contemporary society.
The Book Depository is owned by Amazon too :)
> Also, I want to know what happens with everyone on my news feed

Correct me if I'm wrong, but you can still see everything if you check Facebook enough and scroll down enough. The algorithms just decide which posts to show for the vast majority of users who don't take the time to read every update from all of their X00 friends. If that's true, Facebook is not really hiding anything, they're just guessing which posts you want to see if you're only going to see Y% of the posts anyway.

In which way is Putio similar to Puta other than that they both start with the same three letters?

The pronunciation is completely different, Puta is pronounced 'pooh - ta' where as Putio is 'put - eye - oh' or if pronounced by a native spanish person 'pooh - tee - oh' (in which case the 'tee' would be pronounced extremely quickly.)

I honestly believe this is a false concern.

Venture Lab (venture-lab.org) cannot be unsubscribed from
This is another warning against 1 month old startups, even ones trusted by Stanford.

I signed up with Venture Lab for the Stanford online class in Creativity. However I was disappointed to find out they shared my email address with other course participants and decided to drop the class and close my account completely.

However as it appears there's no such option on their website - you're stuck with them forever. The class cannot be dropped and the account cannot be deleted. Additionaly their privacy controls are not working and they keep sending me notifications after is opted-out 3 times...

I wrote to the contact email provided a week ago, requesting my account to be deleted, guess... no reply whatsoever.

Oh, I don't know. Maybe when he visited the website of one of the largest retailers in the world, broke out his saved credit card like usual, and clicked the gigantic "Buy now with 1-Click" button?

I would love for this to get tested in court. Has it? My understanding (I'm not a lawyer, but heard this from a lawyer) is that the purpose of, say, signing a release form before playing paintball is not because it provides any real protection to the paintball company, but because it makes the signer less likely to sue.

I feel like maybe this is a similar situation? It seems very much like Amazon is "tricking" you into signing away the fact that you "bought" something since the whole experience of the site is devoted to making you think you're buying it. Throwing in a hidden paragraph at the end doesn't change everything.
Startup Execution Transcends the Idea From Day One
I'm a comic book fan, and a while back I started buying comics digitally from Dark Horse's digital store. Being also a HN reader, I'm very aware of what these companies can do, how accounts are closed without notice, wiping all your previous purchases, etc. So obviously as my spending went up in that one digital store, I became concerned of what could happen, especially reading their FAQ that clearly state all my money gave me nothing other than a right to access their online system. So I did like any good geek and I poked around, used a few web developer tools, and found a way to save those comics to PDF, for backup purposes. Now, whenever I buy a new title, the first thing I do is save it as PDF, before even reading it. So now I'm no longer worried about what this company might do, and I encourage everyone who buys goods digitally to do the same. Of course it sucks that we have to do this, but right now that's the only option. Don't let yourself at the mercy of faceless corporations.

You still don't necessarily own a DRM-free copy of something.
DRM is simply a technical method of enforcing a legal license.

Just because you can use a DRM free file in more ways (for example copy and share it) doesn't mean that the license grants you the rights to do so.

One example I remember from the early 90s was "shareware" where you could send off for a free or low cost copy of a software program. These programs were sometimes just demo versions but often actually provided the entire program for free.

However the license stated that you must either delete the program from your computer after some period (usually 30 days) or you must pay a "registration fee" to the developer. Of course without DRM they had no actual way of enforcing this so plenty of people kept shareware versions of programs long after the 30 days which lead to developers releasing only versions with limited functionality for free.
