I'm sure once AOL eventually goes out of business, they can crash on his couch and use his shower. Fair enough he was using their facilities to work on his own projects and try and raise capital, but I admire his audacity. This is probably one of the most impressive things I've heard and read about in a long time.

Well, first there is no question that they're trying to create scarcity: you can create nearly infinite copies of information for basically 0 cost, and they want that to become difficult.

Secondly, it's artificial because they're leveraging the government to enforce it. If they took no action, there would be no scarcity. Therefore it is artificial.

Contrast this with, say, physical goods: even if the manufacturer does nothing about limiting the distribution of whatever you purchased, it would still be scarce because making copies requires significant resources.

Fundamentally, economics is about managing scarcity. The main reason you pay for some resource is because it is scarce. So their "crazy idea" is exactly that: creating scarcity.
Uh, how exactly are you saved from division (and multiplication) on 8L / 100km = xL / 400km? As opposed to just division on 25mi / 1gal = 250mi / xgal...

You can feasibly shoplift as well (not my thing, but I've looked and honestly it doesn't look difficult at many stores), but I don't think anyone is arguing that that you're 'donating' when you pay a store for your socks.

Granted, copying isn't technically theft yada yada, but it sure as hell isn't a donation when you pay the content provider a set price for the content.

On the one hand, the starving serf living in crushing poverty doesn't have much opportunity to get out of serfdom.

On the other hand, an obviously talented young developer who is starving in Silicon Valley may need to take an internship that pays $80K+ per year.

I just realized that Rogue Amoeba isn't just a random company making iOS and Mac apps. They aren't even just a random company that Gruber likes. Rogue Amoeba is a past sponsor of Daring Fireball, including being the debut sponsor of the Daring Fireball RSS feed [1].

Given that, I'd be surprised if he'd said anything else. That doesn't mean what Gruber said here is wrong (I don't think it is), but that is important context nevertheless.

First of all, the complaint has nothing whatsoever to do with the metric vs non-metric issue---we could as easily report gallons per hundred miles if it mattered that much.

Exactly.

The measurement of gallons per 100 miles shows a much clearer picture of gas usage:

MPG = gallons per 100 miles (100/MPG)
14 = 7.1
17 = 5.9
33 = 3.0
50 = 2.0

MPG = Cost of gasoline to drive 15,000 miles at $4/gal (15000/MPG*$4)
14 = $4285.71
17 = $3529.41
33 = $1818.18
50 = $1200.00

It really isn't "free" entertainment. There are many companies making lots of money (zynga for instance) selling virtual goods on facebook with FB credits. FB gets 30%. I'm not trying to say it's the same amount of money that google makes, but that alone is in the millions of dollars per month of gross profit.
I think the point he was making was that the company in question never tried to scale horizontally with MongoDB because, in their words, "we believe horizontally scaling shouldn’t be necessary for the relatively small amount of ops per second we were sending to MongoDB."

Yet, they went and scaled horizontally with Riak and experienced pain.

Their opinion that it did not make sense to have to horizontally scale the "relatively small" number of ops they were sending to MongoDB is certainly their own, but then they horizontally scaled with Riak anyway and boasted about their 25MM ops per day scaling ... which, averaged out, is only about 280 ops per second.

In short, it was far from an apples to apples comparison.

By the time your biz has been developing for Windows for 3 years you should be able to afford the tools. It's not bait-and-switch, it's helping customers use a product to make money with which they can pay for the product - more a "pay only if it works for you" model. Fair enough.

Jobs was absolutely taken seriously by Silicon Valley at that time. There was a period, from when he left Apple, through the NeXT days, that Silicon Valley seemed to understand that he had begun to grow up / mature as a leader. When he first left Apple he was a creative pariah, and many of his peers thought he was a dangerous leader; by the time he joined Apple again, that view had faded almost completely. There were big questions over what could actually be done to turn Apple around, few saw the iPod coming, but most people seemed to understand that Jobs could bring a spark back to Apple that had been missing for a long long time.

I don't think Wall Street believed in Apple much, or that Jobs could turn it around - Wall Street didn't see what he did of course. You can see that in the stock valuation that Apple received during the bubble days, it didn't pop even a fraction as much as other stocks like Sun or Oracle (Sun was worth $150+ billion or so, and Apple around $30 billion; granted Sun was riding a direct wave benefit with their hardware that had sent their revenue parabolic).
I will be very much interested.

Rise of nations has long been one of my favorite games, was just surprised when looking it up that big huge games hadn't gone to far (at least in terms of popular and successful releases) since that.
I see this as just another side-effect of letting a marketing guy (Balmer) take the helm instead of a developer (Gates). As soon as visual studio became segmented into different versions it no longer represented a product designed to increase developer adoption of Windows. Instead, it became a potential profit center. A short-term financial gain at the long-term expense of Windows applications and market share.

Companies that are willing to take long term risks are not valued in a world of high frequency trading. Balmer is hoping that by force feeding Windows 8 Metro apps down developer throats he will convince Wall Street that Microsoft isn't dead yet.

I wonder how that bypass works.
If I'm dealing with [compressed] files on disk or across a network, what's the practical overhead of pv? A few extra percent CPU, or some material decrease in through put?
In practical terms it's not that clear cut. Let's say I have an old car that gets 14 mpg and I'm considering two new cars, one that gets 33 and one that gets 50 mpg.

If I drive 500 miles a week, either vehicle is going to save me at least 20 gallons a week in fuel. But going from the 33 to the 50 is only going to save me 5 more gallons. However to get 50 mpg I probably need to buy an expensive new hybrid, whereas it's not too hard to find a good used car that will get 33 for a fraction of the new hybrid's purchase price. Then you have to consider cost of financing and insurance (both more for the new car). If I go for the 50 MPG car I'll probably never make up the difference in fuel savings unless I drive a LOT of miles.
Combinatorial game theory would be the wrong tool for this, I believe, since this isn't a strictly finite turn-based combinatorial game. (And in my opinion combinatorial game theory is more useful for analysis and proof techniques than for creating AI algorithms, but I've only had one class on it.) The blog mentioned "fruitwalk-ab" uses minimax (with the alpha-beta optimization of course), which is the bread-and-butter algorithm for these kinds of games and I expected it to be in 1st place. Sure enough, it is at the moment. (Edit2: No longer.)

In an intro machine learning course you'd learn about minimax and others, but skip paying any money and just read the basic algorithms here and look up the wiki pages for even more examples: http://www.stanford.edu/~msirota/soco/blind.html (The introduction has some term definitions.)

This would be for things like music and film only, with perhaps some of the money raised handed over immediately, and the rest held until the project is complete.

And, since the musician/filmmaker/whatever has already been paid, a further stipulation on receiving the rest of the money could be that it's released under creative commons license, or something like that.

Seems workable to me. (Either way I'm confused about the downvotes.)
Let's say someone hotwires your car and uses it without your permission to run a delivery business. According to your logic, if you didn't want a scrappy entrepreneur getting a few free rides you should have tightened up your vehicle's security? Maybe upgraded the doors so that they couldn't be opened with a slim jim? Installed aftermarket locks which are unpickable? After all, it's a great hack of the system and didn't hurt anyone and the delivery business will likely create net greater value, right?
> By the time your biz has been developing for Windows for 3 years you should be able to afford the tools

The point is that with their competition, customers are never required to afford the tools.

> it's helping customers use a product to make money with which they can pay for the product

Again, it's helping customers into a position they'll need to be customers in the future, if they have a future. If they don't, why would Microsoft care?
Great point. Today with a $50 virtual server or equivalent, little to no marketing (Google, Facebook, Twitter, Pinterest, StumbleUpon et al. will take care of that), and Google Adsense you can hit $43k a year in sales with not too much trouble.
Yeah, most of the time when someone talks to me about gas mileage, they're interested in better mileage in order to save money or conserve gas, not to go further between fill-ups. So phrasing it as a 33% vs 18% savings hides that you actually save more gas, and so more money, going from 14 to 17 than 33 to 50.
MPG comparisons are pretty intuitive, but where MPG comparisons fall apart is when you're comparing comparisons.

Let's say you have a 10-MPG truck and a 50-MPG hybrid, and you drive both equally far each year, and you've got a $40k budget to replace one or the other.

Should you spend your money on a new truck that gets 11 mpg or a whiz-bang new EREV that gets 100 mpg (equivalent)?

Most people would think that improving the miles-per-gallon by 200% saves much more fuel than improving it by about 10%, but in this case both replacements save the same amount of fuel per mile driven.

If you invert both numbers it's immediately clear that this is the case (10 versus 9 gal/100mi, 2 versus 1 gal/100mi).

I agree. The universe isn't so perfect a place that we can consistently count on all-or-nothing strategies. Sometimes we have to get a little messy to devise a working system. Drug research is a great example of an industry where patents really are necessary to promote the progress of science.
Drug research and development is largely nationalised, at least if we are talking about drugs for preventing or curing the most virulent diseases and not about stuff like viagra.

He's also taking out $20k per year, a whopping four percent. Standard in the financial planning industry is that long term retirees need to keep their annual draw down to about 2% to keep their portfolio steady or growing.

So 4% to spend, 5% in real growth, 2% inflation -- 11% nominal gains per year. That's achievable, but he's going to need to be a damn good investor.
Jobs had just returned to AAPL and was cleaning up the mess left by Sculley and Amelio

And no he wasn't taken seriously at all, he was still remembered as the guy who created the abysmal AppleIII, botched the Mac and then got fired from his own company.

In fact no VCs invested in his second company NeXT, only himself, Ross Perot and Canon did. That company had to leave hardware altogether and was bought by AAPL because they desperately needed a new OS, so ObjectiveC and NeXTSTEP became the founding blocks of OSX and later iOS.

Back then Jobs only recent success had been Pixar's Toy Story.

Re: to it never goes well... I'm one of your aforementioned "College kids [with a] part-time project" to do an MMO, now graduated and working a day-job while trying to finish a game any game.

Let me give you some insight into why we decided and why we thought we could do an MMO. First of all, a subscription model is very attractive, because it's clear how the venture is supposed to make money. We thought, or at least I thought, that we could make an MMO more simply by making a game that's just the "multiplayer online part" plus a smaller "rest of the game". I got started immediately working on the network sync code.

I got as far as moving boxes that did in fact sync their positions on multiple computers. But going from that to a real game is about as big a gulf as going from nailing boards to building a house. It turns out, code to network sync a game is not going to go anywhere without a game to sync.

So now I'm working on a simpler single player game, built with the scripting language bindings that was one of the best pieces left over from the earlier endeavor. I think even experienced programmers from other fields cannot understand the soul-crushing amount of work it is to get even simple things working in a 3D game when you're doing it all by your self. Yesterday I got a green line to move on a black screen, and I was happy.

(The game engine, which can do more than that, had been not working for 6 months following a rewrite, so I was happy to see anything. And yes I know about the Joel Spolsky article about the folly of complete rewrites. I'll see your Joel Spolsky and raise you one Richard Brooks: "plan to throw one away. You will anyway.")

For anyone that is doing CS at Columbia University or considering CU, if you like these types of coding challenges, definitely look into Professor Ross's Programming and Problem Solving class. It was one of the best CS classes I took at Columbia.

Here is his website:
http://www.cs.columbia.edu/~kar/teaching.html

Each semester consists of 4 different open ended programming problems like these. You work as a team to compete against other members of the class. There's no tests and each class is run as an open seminar where people talk about their strategy and implementation and consider the best approach to solving these problems.

This was my favorite from my year: http://www.cs.columbia.edu/~kar/4444f02/node18.html

You should look at the basics of AI and various search algorithms.

The first priority would be to quickly pick up the vocabulary: what is a state, what is a utility function and so on.

I recently took a class on AI and we used the (rather popular) Artificial Intelligence: A Modern Approach by Russell and Norvig [1]. I didn't actually read the book, but I've heard good things about it so it's definitely worth a look.

[1]: http://aima.cs.berkeley.edu/

All the lectures for the course are available online as well[2]. The professor my semester (Dan Klein) was a brilliant lecturer, so the lectures are worth watching if you have the time. The lecture notes[3] are also online.

Of course, if you want to participate in this game, you are doubtless in a hurry. So you might want to skim through lectures 2, 3, 6, 7, 10, 11 in roughly that order--they seem to be the most pertinent.
You said:

> Android on mobile shows us how spyware and viruses are a very big problem without those restrictions, compared to, say iOS

Which I took as saying Android is inherently less secure, but I agree after your clarification that isn't what you were actually saying.

That said, this doesn't show Android is more susceptible to viruses than iOS devices, and iPhones are not immune to botnets either (http://nakedsecurity.sophos.com/2010/03/09/8000-iphone-andro... - though this only affected jailbroken iPhones). Previous jailbreak exploits that worked through Safari could have been disastrous as well - it's not that iOS is more secure, but I do agree it seems to be less targeted. As the popularity of iOS seems to be on the rise I believe this will change.
If you really want to crunch numbers, I highly recommend Haskell. It falls short of Python in terms of libraries and by some accounts, readability, but it is substantially faster and excels at number crunching. I find it easier to express number crunching in functional rather than object-oriented style programming. Python has lambdas, but usually theres a more pythonic way to express something in Python. Although I must say, I find Haskell's list comprehension syntax slightly more elegant.

http://tryhaskell.org/

edit: I take it back about Haskell's list comprehension syntax. At the end of the day they're both great. Haskell's syntax just feels like reading set theory notation.
But the valuable lesson they would draw from it all is "we need to patent every thought a Microsoft employee has", which is probably not the lesson you're imagining.

I disagree. There's a difference between valuing NeXT as a business and valuing Steve Jobs as a visionary or creative genius. Investors didn't believe in the business prospects of NeXT, but Jobs was still very highly regarded by the valley.

This is a fantastic article. I'm glad to see that I have picked up some of these rules intuitively, from reading others' code, and studying the design of Apple's APIs. I do have a couple questions though, that hopefully someone can answer.

With the introduction of blocks in iOS 4, some APIs have shifted to using blocks for messaging. What is the general opinion on this?

Also, for components that benefit from an internal state machine - which is best practice to notify objects of a change in state? Delegate messaging, notifications, or just KVO?

If they're saying what I think they're saying then I think a simple screenshot of an image sharing menu from a well chosen iOS camera app would probably do the trick for "the problem" but I'm not convinced their "solution" would be any better (instead of share via one of twenty different services, you need to pick which of twenty different features from one service to check off).
