"Never", huh? Seems to me like an extremely strong statement for a security officer for a major operating system to be bandying about.

Your proposal also treats a 2-way cryptographic function as a 1-way cryptographic function. That is, optimistically, a questionable thing to do.
What most people don't realize, is that the "physical" cost of a book isn't a particularly significant portion of its cost at low volumes, and very little of its risk (You can do multiple printings should a book do better than expected)

The author here:
http://www.tobiasbuckell.com/2010/01/31/why-my-books-are-no-...

Did a great job of capturing many of the costs of publishing a book - Author's Advance, editor, copy-editor, proof reader, typography, design, art, Marketing/Advertising - regardless of whether it is physical or electronic.

I've only ever been on the periphery, as a technical editor - but I can tell you, watching the birth of even _one_ book, is a painful, extensive, and incredibly expensive process involving a ton of highly qualified professionals. The actual "physical" production of the book is almost an after-thought. And, every author I know in the technical industry, has always had to have a "real job" in order to make a living.

So, no - I don't actually think there really is much difference between the cost of a physical book and an eBook for normal volumes < 10,000 copies, which is considered a good success for most authors - the fixed costs are pretty significant.

I do agree with you, though, that there are a lot of liabilities associated with DRM encumbered eBooks, that hopefully publishers will drop, and therefore _enhance_ the value of eBooks. I certainly am willing to pay more for a non-drm encumbered eBook than it's paper equivalent. With the number of Ebook readers I have (iPhone, K1, K2) - they simply are more valuabe.

Stephen Colbert gets ahold of an iPad during the Grammys
Has anyone gotten their hands on one? I can't find any online store in the US selling them, and Intel's website doesn't even mention it. I have a feeling someone just changed 160 to 320 in an existing model number.
They mean you should read the book to find out. Making bold and outlandish claims is a typical way to get people to look at your product.
Libraries aren't exactly convenient for normal consumers. To go against your video game and cd relation to a book: Video Games are targeted to a very large market and the majority of games today tend to offer much more than 2 or 3 hours of entertainment especially if you take the case of online play; CDs are in a market that is surrounded by piracy and yells of corruption but to take the price point a cd usually offers much more value than 70 minutes of entertainment and one popular way to consume music and purchase it is through itunes which does indeed offer lower prices for basically the same content.
The current standards are a decade old already, HTML5 has been 6 years in the making and will probably be another 4 or 5 years before it reaches a market penetration that makes it an generally-viable design decision rather than what it is now - a device or browser specific option.

Work probably won't even start on the HTML6 specification for another decade at least while they wrap up all the formalities for HTML5, and identify where it needs improvement, and slowly discuss and agree on those improvements. Years after that browsers will start supporting it feature by feature, and years after that enough users will have access to enough features to call it mainstream.

That process is very likely to leave us having this same discussion about whether HTML6 will kill Flash in 2030. Assuming anyone still makes or cares about any of this stuff that far in the future.

Where we are now with HTML5 the void between HTML5 and plugins (Flash is just the most significant) is smaller than it's ever been before, but the fallacy of that argument is that Flash, Silverlight, JavaFX, Unity, etc are in active development and release cycles.

They make significant progress year after year, just like desktop software, operating systems, programming languages etc, and while HTML5 almost catches up right now this is as close as it's going to get at this time.
Actually, it worked exceedingly well. I mean, breathtakingly well. Basically, the economy expanded incredibly, aside from a brief and mild recession at the end of elder Bush's tenure, from the time Reagan enacted his tax cuts, to midway through younger Bush's presidency. Reagan experienced an unparalleled peacetime expansion and then Clinton broke his record.

We are in a recession now, but it's pretty hard to link a causal chain including tax cuts to it. In fact, we know exactly what caused our current situation, and no one thinks it was "the tax rate was too low".
It doesn't seem possible to consistently make "1 < 2 < 3" a syntax error in a language powerful enough to redefine <. (Including Haskell, where you could easily hide the Prelude definition and define your own, also changing the fixity declaration.)

So I guess a fair compromise would be if the default implementation rejects "1 < 2 < 3" at either compile-time or run-time, whichever is possible.
Regarding 132 dpi (well, ppi--displays have pixels, not dots), 132 is pretty dense, but 72 ppi displays are not the standard anymore. In fact, a 15" diagonal display with 1024x768 resolution has 85 ppi, and I think that's about as low density as you'll find. Netbooks are around 120 ppi or more. A cheap 15" Dell LCD is 110 ppi. I'd guess the average is now closer to 100-110 than 72. And all the higher density means is that your images will appear physically a bit smaller, but since the detail is exactly the same (a 300x400px image is 300x400 regardless of your display's pixel density), I'm not sure it matters much.
They dropped the price of DRM-free tracks to be the same as DRMed tracks way back, and during the first quarter of last year they removed DRM from all of the songs in their library.

Some music videos are still DRMed, but all songs are DRM-free 256 KBps AACs for 99 cents.
I've suddenly started looking at hardcover buyers with more respect. These people aren't suckers, or at least they aren't mere suckers. They are the patrons, the hardcore fans, that are keeping my favorite writers in business.

For years I felt proud of that -- as I mentioned yesterday, I used to buy hardcovers pretty indiscriminately. I'll happily pay extra for quicker access. That's why I shelled out $350 for the machine which teleports books directly into my hand. When I hear publishers talking about windowing books on my Kindle to protect their no-longer-relevant-to-me hardcovers and physical distribution systems, I get a little upset. I mentioned so on my blog.

This morning, I woke up to an inbox full of mail from people who profess to be professional communicators telling me that I "stabbed them in the back" and was a "useless parasite" and "tightwad" for expressing my desire to continue paying them thousands of dollars in return for fastest possible access. I think of myself as a patron. They clearly think of me as a sucker. Did the Medicis ever have to put up with this? Of course not: in addition to hiring artists they also had assassins on the payroll. I'm strangely tempted.

It seems like six authors have a radically different understanding of the patronage relationship than I do. In a not totally unrelated turn of events, today my To Read list got shorter by two books.
It's probably a variation on 'opinionated software,' if I had to guess.

No. iTunes went DRM free nearly a year ago. You can’t buy any music with DRM from iTunes even if you wanted to. (That doesn’t apply to some music videos and all other video content as well as iPhone apps.)
Expensive Web Design
Are you considering designing your website because hiring professional web design firms is not worth the expense? If you are, have you considered what a poor website design would cost your business?Many people think professional web design services are expensive. This is primarily because most people don’t really understand why they are paying such high fees for just pretty website graphics and colors. When you pay less you get just what you pay for – less web traffic, less conversions and less profits.
Just wanted to add that you can create an icon for a web app that on the home screen and it will look and act like a native application (e.g. the mobile safari tool bar and address bar won't appear).
If you controlled the passwords your users chose, you might be in a position to talk about "strong passwords" combining with "salted hashes" to make a reasonable solution.

Here's a bcrypt hash. Crack it, and I'll donate $200 to the charity of your choice. It's not random, and the cost factor on the hash is not high.

In modern US cities there are a lot of different manholes, mostly round and rectangular - some shafts don't go deep, so there is no need to make shaft round.

I wonder what kind of shaft is under triangular cover, why would someone build triangular shaft? :)
By the way, Richard Revis(not sure if that's you) gave a fantastic talk (http://www.youtube.com/watch?v=os1NevFafNA) about the neat stuff you can do with JS (http://theplanis.com/clouds/) the other day at my university.
I had upgraded using that and I didn't even know it.
Crime & Punishment on the Internet: Should we forgive a thief?
There's a difference: bcrypt (and moreso scrypt) were designed to be hard to speed up, while SHA1 was designed at least in part to be easy to speed up.

But in practical terms, "stretched" SHA1 is fine. I won't bitch at anyone for using it.
Why was this post voted down? It was very insightful. Is voting down if one disagrees with the post okay or something?
Even in a mathematics, "a < b < c" isn't an expression but merely shorthand for "a < b" and "b < c".
It's an idea roughly analogous to SRP, which is well-studied. Share a key, then later prove you still know it.

Client-side hashing would be great, if there was a way to do it that didn't involve Javascript.
I'm sorry if I'm completely misunderstanding, but couldn't a hacker generate a rainbow table once - of all the common passwords, say - and then, once they get a copy of the database in which the password hashes are stored, simply compare them? In the same way that md5 rainbow tables exist, which greatly reduce the computations required when looking for passwords?

Unless, of course, you salt them (which would turn it into 4.8 months to break all the common passwords in a table, building a rainbow table with the salt taken in mind - the only situation in which you're spending 4.8 months per user is if they're each salted differently, for example with the username)- but the article doesn't suggest salting bcrypt, so I'm ignoring that.
Sure, but in practice in most cases it seems designers chose to make cover of the same shape as the manhole it covers.
Hot Code Loading in Node.js

Quick and Dirty(probably better ways to do it):

def permute(string, prefix = ''):
if len(string) == 1:
print prefix + string
return

for x in range(0, len(string)):
new_prefix = prefix + string[x]
unused_chars = string[0:x] + string[x+1:]
permute(unused_chars, new_prefix)
Sounds pretty good being in Melbourne myself and not really being regularly surrounded by people really interested in start ups.

The Joy of Clojure, my perspective.
Offering iPhone optimized sites is important because there are 75 million iPhone/Touches out there give or take. I'd be surprised if there are more than 3-5 million iPads out there by the end of 2010 so it's probably nothing to get too bent out of shape about.
Neither will take books in English. The best option I have is giving them away to friends, and I can't do that fast enough to keep pace with my buying.
Why have a "coming crisis" when you can have one right now?

I mean, I doubt the present "recovery" is going to last more than a couple of years. The problem, actually, isn't the government spending money like crazy to get us out of the crisis. The problem is that government is spending the money on ... the same perps who got us into this mess to begin with

Plus I wouldn't trust Ken Rogoff's research papers any further than I could throw them - I've followed him for a short while:

Two interviews: http://www.onpointradio.org/shows/2007/11/wheres-the-economy... http://www.businessinsider.com/henry-blodget-rogoff-the-wors...

In the first, 2007, he touts the US economy to the sky against some skeptic. In the second, he angry denounces all the people who didn't see the mess coming - which includes he himself in the first interview! I kind of agree with Rogoff(II) - the liars should be held up to some sort of standard. Why's he still around?
Astounding. Where was this alarmism while the Republicans were spending money in the Middle East like drunken sailors and we were in the last recession?

Oh - sorry. Military spending is always OK. My bad.
Nice detailed write-up.

Couple additional details worthy of discussion:

1) Covers also can have hinges, so training of personal may be not even required.

2) It's unclear that round cross-section is the most convenient for humans to climb, after all humans in horizontal cross-section are like elongated ovals, so rectangular shape could be better. :)

I thought the dimensions and aspect ratio sounded a little weird at first, until I realized that they were almost exactly the same as the marble-covered composition books that pretty much everybody who has ever held a pencil has used at some point.

I've been carrying one around since the announcement, and I gotta say that aside from video, it's probably the most perfect size they could have picked.
I would say it is up to each person's individual values whether to forgive. But this guy is asking for his acts to be expunged- which is more than should reasonably be expected.
Sounds pretty awesome. I'll be out of town that weekend though. :-(

Where To Find Real £100 P/H Part Time Work From Home
Times are tough, and finding a good part time job is becoming more and more difficult with each passing day. With potential employers looking to cut back on costs wherever they can, the number of available part time positions is dwindling, and the number of people seeking them is growing. If you have found yourself having difficulty finding part time work, this article will provide you with some tips and tricks on how to find steady part time work from home.
I agree esp when you are in trenches with your startup morale does go low. With a very stressful and disappointing one year in 2008 even I said No to 3, 12 & 23.

23) I do not frustrate easily

Getting much better off-late though. Positive reinforcement from your own work works best, even if they are small.
What about going through the list once, put each node onto a stack, then pop n - 1 elements off the stack, and the nth last element will be on the top of the stack.
Edit: uses too many pointers as cperciva points out below.
Two wrongs don't make a right here, but if there's going to be a coming crisis, it's going to be a bipartisan crisis that both parties are very much responsible for. I think you'd find that most Americans - Democrats, Independents and Republicans are unhappy with how much was spent under Bush, but by the same token, I don't think it's unreasonable to note that the deficit under the Obama administration last year alone was $1.074 trillion dollars while the Bush administrations had an average annual budget deficit of about $104 billion per year.

Let me repeat and rephrase given how stunning it is - the Obama administration's deficit last year alone was greater than all the deficits combined under the Bush Administration including all the war spending. I think it's fair to argue that last year was unusual but deficits are also projected to remain high for the forseeable future and the Obama administration has additional significant spending programs in the years beyond his current proposed modest spending freeze.

EDIT - I erred - I used an average of 104 billion under the Bush administration when it was an average of 104 billion under the 12 years of the Republican controlled budgets which extends into Clinton's last administration. However the data including, I believe, war expenditures can be found here (excel file): http://www.cbo.gov/ftpdocs/108xx/doc10871/Historicaltables20...
How Many Calories a Day to Lose Weight
MacMillan; Subsidising the old with the new since 2010
This is a false choice.

There are more choices in your professional life than:

A) Being 9-5 daily grinder (for some reason this is always implied as being a bad programmer -- why?)

or

B) Working your ass off for some schmuck for terrible pay who gives you free snapple and a (perceived) enjoyable project.

In either case: THE FINANCIAL REWARDS ARE NOT GOING TO YOU - (Drinkers of the VC kool-aid this means you too).

To every passionate developer out there I challenge you to milk your 9-5. Then go home and make what YOU want, and live and die by that effort.

Take both of these perceived benefits for everything you can. The security and stability of the 9-5, and the sense of enjoyment/accomplishment/financial reward from your independant work.

Do not work for other people except as a means to a guaranteed paycheck.

Do not let others enslave your passion and creativity.
But perfect advertising is when you're looking for a car, and you get presented with information about a (more expensive) car that you buy, but that you wouldn't have bought if you spent time doing the research yourself.

This is a worse outcome for you, but a better outcome for Google and the manufacturer.

I'm not sure if this is possible, presumably if there is something that would convince you to buy it, enough research on your part would hit the same thing and you would buy it anyway - in that case it would be the same as your suggestion - but you wouldn't be doing research on "what's the most expensive car I could possibly convince myself to buy", you would be researching "what's the cheapest" or "the best form/function/cost trade".

It still seems like good search results are what you'd want when buying a car, and adverts are what you wouldn't want.

What would it take you to get into a state where you skip researching a purchase and take the first advert Google shows you, confident that it would be close to what you'd have found anyway?
I know. Don't make anything cool, because someone might misuse it.
> When I hear publishers talking about windowing books on my Kindle to protect their no-longer-relevant-to-me hardcovers and physical distribution systems, I get a little upset.

It's important to note that Macmillan was only considering windowing books on the Kindle because Amazon was forcing them to sell their books at a price below what they believed was profitable. Had Amazon been more flexible in allowing publishers to set prices for the content they own, then this never would've happened.
This article describes any easy way to do this incorrectly.

It also has simple spelling errors, such as 'weather' for 'whether'.

It is NOT what I've come to expect from HN. Downvotes for everyone involved.

Oh. Right. I can't downvote. Damn.
I think some responsibility needs to be borne by those creating blatantly insecure systems.

If I leave my garage door open and you come in and steal a server, sure, that's illegal, but if, say, I lock my garage door, (or otherwise take reasonable precautions) you break a window, and then steal the same server, your penalty will be greater.

depending on equipment on the consumer premises to be secure (especially if your system is so weak as to just look at the mac address.) sounds to me a lot like leaving the garage door open.

I think this goes doubly for the banking systems; right now, all I need in order to hover all the money out of your bank account is your checking account number (and a merchant account) and your checking account number is on every cheque you write. That's a ridiculously insecure system, and sure, it should be illegal to exploit that, but I think the banks are 'leaving the garage door open' here - they bear responsibility for not taking reasonable precautions.
For me (and I don't claim this calculus works for anyone else) an ebook is overpriced if I can get a discounted or used copy of a print version for the same amount or less. The print copy has intrinsic value; I can resell it, lend it out, donate it to a "books for prisoners" program or leave it to my grandkids; it requires no additional hardware, and I'll be able to read it anywhere, anytime for the rest of my life. If I drop it down a sewer grate or forget it in a cab, I'm out no more than the replacement cost of the book (which is probably out in paperback now). If I throw it in a box in the attic and leave it there, barring the Rise of the Silverfish I'll be able to pull the box back down again in ten years and pick right back up reading it again.

But the electronic copy has no intrinsic value; I can't resell it, lend it out, or donate it; it requires additional hardware to use, and I can only read it on the platform(s) the vendor allows me to read it on for as long as the vendor allows me to read it. If I'm reading on my PC, I can't change platforms or upgrade my OS unless the proprietary reader software is available for the platform/OS I'm moving to. If the vendor decides to adopt another format or leave the business entirely, my books suddenly have a drop-dead date: once my hardware breaks, I lose the titles I've bought forever.

A lot of these issues go away with non-DRMed titles, but in all but a few cases (bulky tech reference titles for example) a DRM-free eBook is still unlikely to be worth as much to me as the print version.

And you really don't want to get into the "dollars per hour" argument here. The iPhone game I just finished up cost me a dollar and I got a good 20+ hours of play time out of it. But I can get through an average-sized book in four or five hours, so if I went by price per enjoyment-hour, it'd make that book worth about twenty-five cents. (I'm cheap, but not that cheap...)
