I have a kindle, and I very much like the convenience of being able to manage my library by easily moving books on and off of the kindle wherever I am. However, any time I buy a book from Amazon I first check if a DRM-free alternative is available elsewhere. I don't do this because of principled opposition to DRM (I am opposed to DRM on principle, but it's not why I do this); I do it because I want my books to be as portable as possible, not locked in to any one merchant, platform, or device. Unfortunately, in most cases the only option is a file with some other form of DRM that won't work on my kindle. If the big publishers stopped using DRM, I would stop buying ebooks from Amazon and buy all of them directly from the publishers.

If such were to happen, I'm sure that other people would offer cloud services that would allow you to upload your eBooks from wherever you buy them and then access them from your device over your choice of wireless carrier. If they lost enough market share, I'm sure that even Amazon would start offering such a service.

> In other words, the choice is never "Forge these results, or have no career."

Yes it is, because in order to have a career, it is not enough to just publish. You have to publish in prestigious journals and you have to publish original, groundbreaking, important, and meaningful research.

A tiny percentage of academics actually end up keeping their job until retirement. If you don't plan on perishing, you publish in prestigious journals by whatever means necessary. Whatever. Means. Necessary.

"Accidentally" using bad statistics is the kind of "accident" that gets you tenure. It's significantly easier to forge groundbreaking, important, prestigious research than it is to actually do this research.

Scientific fraud is epidemic precisely because of the economics of universities.
This made me think that we can expect to see ebook wars like we are currently witnessing with other media, e.g. iTunes, Netflix, YouTube, Hulu. If, say, three of the big six publishers end up creating their own marketplaces with their own formats and DRM, and possibly even their own devices, while pulling their ebook titles from Amazon and B&N, I can't help but think it will be a net loss for customers and of dubious advantage to the publishers. I wonder if Amazon's dominance would make this too little, too late. Something tells me there's still room to maneuver, but perhaps not for long.
> Contracts of adhesion, in my opinion, are more of the problem

In the Internet/data mining era, contracts of adhesion are an incredibly overpowered legal tool. Suddenly things you used to do in person, with reasonable expectations and no practical way for commercial entities to override those expections, have been replaced by doing everything in software and on-line, with EULAs and click-through agreements that contain numerous obviously abusive terms that are not necessary for the performance of the basic agreement, would be unexpected by the individual agreeing to the standard form contract, but are never known (until it's too late) because no-one actually reads the full details of every form agreement they "agree" to.

It is well past time that consumer protection laws were updated to dramatically rebalance the legal weight of form contracts containing potentially unexpected or misunderstood terms against what would seem necessary and reasonable to the person entering into such an agreement.

It is also well past time that privacy laws were updated to reflect the Internet/database/data-mining age. You can't just assume that some minor action that might not in itself have been considered an invasion of privacy in more innocent times is still harmless at a time when technology can turn a collection of such actions into a searchable life story.
Honestly, if the author line had said "Tyler Winklevoss" I wouldn't have been surprised. This individual has confused "responsibility is hard" with "responsibility sucks," which is a very poor comparison to make if you want to do anything well.

Having noticed "Hanlon's Razor" becoming the default reaction for a number of HN posters, I have to say what I feel is really bad about it when it applied to complex human endeavors.

When one deals with modern institutional corruption, what one is dealing with is a complex combination of incompetence, overt deception of others, self-deception and simulated incompetence.

Sure, incompetence is in the mix but when you use a construct like "Hanlon's Razor" to "label and forget" the situation, you hide the full situation. The complexities of these situations are there, there is no razor for a priori untangling.
I agree. I've found that since I discovered the two-finger scrolling on my MBP (and to a lesser extend, the scroll wheel) that I'm usually continuously scrolling while my eyes remain relatively fixed rather than using spacebar or page down.

The telling statistic for someone such as yourself, would be how much do you use non-kindle reader software. If you are using the kindle app on your phone, tablet or laptop the author's point is still valid. You are (willingly!) locked in to Amazon's kindle ecosystem; even if you aren't using the device itself.

I have used Git on only Windows and Mac, and these are my experiences:

Installation on Windows is easy – just use msysGit[1].

I don’t know about performance because I never worked with large repositories.

For usability, all the command-line options and tools work as normal, and git gui is equally usable/unusable as it is on Mac. Mac does have a wider selection of GUI front-ends for Git, including my favorite, Tower, but Windows does have a few, including SmartGit, which is enough for simple usage. Windows’ command line program is harder to use than Mac’s Terminal, but the free program Console[2] gives it most features I need.

>Mathematically, an n-dimensional space is R^n, that is, the cross product of the real numbers (R) with itself n times. Each copy of R lets you specify a number independently of all the others.

See, that's exactly what I'm talking about. This gibberish makes sense to no one except a mathematician. The explanation I've given - while maybe the same in essence - conveys the meaning in a comprehensible way that's not completely removed from reality.

My point is that mathematicians often do neither realize that they are talking gibberish that makes no sense to anyone but themselves nor do they accept that math without proper context is devoid of any meaning (outside of math, that is).

NOTE: I would like to clear up that I'm not attacking math itself. I neither think math for math's sake is bad, nor do I think math is useless. I respect math as a self-contained field. The problems I'm pointing out are all happening where there is application within other fields - such as CS.
I certainly didn't take you to be suggesting not to hire the candidate based on their credit score, I'm saying it would make me uncomfortable to force them in to disclosing explanations for it in the first place because those reasons quite likely have nothing to do with how good of a candidate they are. What I was saying is that you might lose some good developers because they don't want to work for a company that would make such a request.

Anyway, I see your point, but this is where we part ways because I think that being asked to explain a 2.5 GPA or a horrible review from a former manager are materially different than being asked to explain a low credit score. Sometimes folks' personal and professional lives intersect in ways that require them to disclose more than they might want to to explain that bad GPA or bad review; that's unfortunate. But unlike GPA or a reference check, there is no "professional" component to your credit score that necessitates such disclosure, just as there is no professional component to one's religious affiliation or marital status. That the first of those things is sometimes legal to ask about (check your state's laws) and the rest are not doesn't make it OK. Anyway, I think we at least see where our disagreement lies; I take your point, but I just don't see a credit score in the same light.
Agreed - I think his fundamental 'flaw' may be be his MBA-ness meaning he is looking for the efficient, predictable, safe way to make money for the organization which in this case is himself. Its been said over and over but for the majority of people entrepreneurship is typically not the 'best' way to make money or going to make one materially wealthy beyond their wildest dreams - in most cases its probably going to be better for your spreadsheet if you just get a normal job. BUT a normal job 9 times out of 10 does not 'pay' anywhere close to the things one will get out of an entrepreneurial effort that is the right fit (meaning doing what your passionate about, living your life your way, etc.)

Right free = 50% (or equal share if there is more than one partner) if not you can work on your own idea for free and keep 100%. To me this deal stinks, it also smells really bad by the fact that salary will be negotiated once they are funded when you have far less leverage to bargain with. Right now you have everything that they need yet they want to stack the deck totally in their favor. My personally experience with individuals like this is they will only get worse if they do get funding. I would run for that deal fast, it is so low and so one sided that you will never get a fair deal and if you do they will look to deprive you of it at any opportunity. They think that you (your role) are worthless. The offer is evident of this, they have the if we could just get some laborers to build this we will be rich mentality. They view you as a cog that is worth $20 an hour, their mentality will not change once they are funded.
What if there is seasonality in your Churn (lets say in your example monthly, which is very reasonable) and you are growing?

If you calculate at the wrong time you will severely skew the numbers.

-

Its my opinion that if you have daily churn numbers and you want to be the most accurate, simple formula is no longer viable. You should model daily churn against daily sales and create a revenue model. (takes about 2 minutes in excel, less if you have the data already in a spreadsheet).

-
If you want a simple formula, you should use the first two formulas you described in the article and just see how the numbers "feel".

In my opinion, anything beyond that introduces unnecessary levels of complexity that may actually make your modeling less valuable.

-
In any event, the article is great and really got me to think about churn again. Well done, and I really liked your thoughts.

It's not just you. I intentionally went for the 11" MBA because I want a portable computer to be...portable. I'd rather have an external monitor, keyboard, and trackball at home and work, and keep the machine itself as lightweight and compact as possible.

It does matter a little bit if you're in a hotel or something, but the minor inconvenience of the smaller screen is outweighed by the savings in bulk and weight, at least for me. Obviously others have the opposite view. Different strokes, I guess.

Hmm... there could be a business opportunity for the hotel industry here. How about offering nice monitors and keyboards as in-room amenities?

Advertisers pay platform owners to have sex with user data. That does not sound nice, but it's an analogy that most people can understand.

The advertisers are the Johns (paying customers). The platform owners are the pimps. The users are the whores. Once you understand that, things become crystal clear. The more whores a platform owner has, the more they can charge the Johns to fuck the data. Pimps fight over whores and try to keep them from leaving. They fight over territory too.

Well, Jobs' desire for a small, quiet (fanless) machine drove them to hire Rod Holt, who designed the switching power supply for the Apple ][. Jobs quote from the bio (it's unclear when he said this): "That switching power supply was as revolutionary as the Apple ][ logic board was. Rod doesn't get a lot of credit for this in the history books, but he should. Every computer now uses switching power supplies, and they all rip off Rod's design."

Would the Apple ][ have been as successful without the switching power supply? Hard to say. But even at the Apple ][ stage, Jobs' design sense was making its way into Apple products.
The print edition doesn't include Chapter 7 ("Searching") from the web edition. (There may be parts of the other chapters missing, but I'm not sure.)

That said, Chapter 7 of the web edition begins this way:

> This chapter does not introduce any new JavaScript-specific concepts. Instead, we will go through the solution to two problems, discussing some interesting algorithms and techniques along the way. If this does not sound interesting to you, it is safe to skip to the next chapter.

So maybe the author or the publisher (or both?) decided that chapter was a distraction or somehow wrong for the printed version.

Not exactly high school. I'm a university student in Germany.

But yes, it's pretty much a bad experience. I've seen quite a lot of other students which are otherwise bright persons struggle with math simply because they aren't good at learning to interpret arcane sequences of symbols which pretty much represent nothing relevant to reality. Math the way it is taught here is essentially useless for 95% of all CS students.

Yes, it truly is annoying that, in Windows, one cannot use a few page up presses to quickly look up say a function name, then hit, say, cursor right to automatically scroll back at the point one was at :-)

The rationale for choosing this behavior in the Macintosh human interface guidelines was one of consistency: the keys simulate clicking the page up area, and clicking there does not move the cursor.

The keys _had_ to emulate mouse behavior because not all users had page up/down keys. The original Mac keyboard did not even have cursor keys.

I also think Apple that way avoided the difficult choice of what to do with the cursor. Should it stay at the same screen position, move to the top of the window, or something else? What if scrolling hits the top/bottom of the document? What if one hits page up while already scrolled upwards as far as possible? Should the cursor move within the document?

Finally, there is consistency with other programs. Drawing programs, photoshop, file explorers, etc, typically do not move the selection on page up/down.

I think they made the best choice for that time. It may no longer be the best choice in today's world where six year olds have six years of experience working with GUIs, but the eighties were quite different.

Note that the bound (as given in the paper) is now even better than the one mentioned in this blog (and the title).

This is of course huge news after twenty years of people trying to crack this.

You need matrices of dimension 1.66x10^91 before this result yields half the number of steps. But if an algorithm exists which made effective omega = 2 then this could have huge implications. So any improvement in techniques, no matter how slight, is very welcome, as it may lead to much more significant improvements later on.
