Shallow thinking about filesharing

Monday, February 7th, 2005

Tyler Cowen “cannot accept the radical anti-copyright position” and so proffers apologia for the radical intellectual protectionist position. (NB no anti-copyright position is being argued in MGM v. Grokster.) Regarding Cowen’s three arguments:

1. In ten year’s time, what will happen to the DVD and pay-for-view trades? BitTorrent allows people to download movies very quickly.

BitTorrent downloads tend to be faster than those on typical file sharing networks but still very slow. Netflix is a far superior option unless you place a very low value on your time (in addition to waiting many hours in the case of BitTorrent to weeks in the case of eDonkey for a download to complete you also need to spend time finding active torrents or hash links and dealing with low quality, mislabled and overdubbed copies, which often means starting over, even after you’ve learned how to deal with all of these. I pity the computer semi-literate who just wants to snag some “free” movies) .

Note that DVDs already account for more than half of Hollywood domestic revenue. Furthermore the process will be eased when TVs and computers can “talk” to each other more readily. Yes, I am familiar with Koleman Strumpf’s excellent work showing that illegal file-sharing has not hurt music sales. But a song download can be a loss leader for an entire CD or a concert tour. Downloading an entire movie does not prompt a person to spend money in comparable fashion.

Radical protectionists said made similar arguments about the VCR, as have those in countless businesses faced with new technology. In the case of the VCR, entrepreneurs figured out how to use the new technology to make billions. Similarly, it should be up to entrepreneurs to figure out how to thrive in the environment of ubiquitous networking, rather than up to lawmakers to ensure existing businesses survive technological change.

2. Perhaps we can make file-sharing services identify (and block) illegally traded files. After all, the listeners can find the illegal files and verify they have what they wanted. Grokster, sooner or later, will be able to do the same. Yes, fully decentralized and “foreign rogue” systems may proliferate, and any identification system will be imperfect. But this is one way to heed legitimate copyright suits without passing the notorious “Induce Act.”

Fully decentralized filesharing systems have proliferated. LimeWire is #2 at download.com and several other decentralized filesharing clients make the top 50 downloads list.

The imperfections of an identification and blocking system will include invasion of privacy and censorship.

3. I question the almost universal disdain for the “Micky Mouse” copyright extension act. OK, lengthening the copyright extension does not provide much in the way of favorable incentives. Who innovates with the expectation of reaping copyright revenues seventy-five years from now? But this is a corporate rather than an individual issue. Furthermore economic research indicates that current cash flow is a very good predictor of investment. So the revenue in fact stimulates additional investment in creative outputs. If I had my finger on the button, I still would have pushed “no” on the Mickey Mouse extension, if only because of the rule of law. Privileges of this kind should not be extended repeatedly due to special interest pressures. But we are fooling ourselves if we deny that the extension will benefit artistic output, at least in the United States.

The paper Cowen links to above (Cash Flow and Outcomes: How the Availability of Cash Impacts the Likelihood of Investing Wisely) is hardly encouraging regarding the efficacy of additional investments correlated with increased cash flow.

Eric Rescorla points out that subsidizing organizations that happen to hold copyright to work created 70 years ago is hardly the best way to subsidize new content creation, should one wish to do that.

Mass Destruction of Software Patents

Thursday, February 3rd, 2005

Is there something in the ether? Two people “near” me declare software patents potential “Weapons of Mass Destruction” yesterday and today, apparently having been struck by the idea independently: Patents as WMD’s from Mitch Kapor (Creative Commons is housed in his office space) and On Software Patents and WMDs from Ben Adida (who represents Creative Commons at the W3c).

Kapor and Adida have different scenarios in mind. Very roughly North Korea and Al Qaeda respectively.

See also Wikipedia on the software patent debate.

Faith

Friday, January 28th, 2005

I’ve been meaning to write an essay much like Robert Wright’s Op-Ed in today’s New York Times for a few years.

Mr. Bush doesn’t grasp the liberating power of capitalism, the lethal effect of luring authoritarian regimes into the modern world of free markets and free minds.

Interventionists, in particular George Bush, talk a lot about freedom and liberty. So did the last century’s communists. Neither had or has any faith in actual freedom as their actions forcefully demonstrate. Read Wright.

[Via Chris Sciabarra.]

While on the subject of faith I must point to the Church of Reality. “If it’s real, we believe in it!” Ah do buhleeve!

A lie halfway fulfilled

Thursday, January 27th, 2005

Excerpt of Bush adds $80 billion to wars’ costs Afghanistan, Iraq tally would pass $300 billion if OKd from yesterday’s San Francisco Chronicle:

Before the March 2003 invasion of Iraq, estimates of the war’s cost were $50 billion, with assurances from administration officials that Iraqi oil revenues would pay for much of the effort.

Asked Tuesday how the administration’s estimates could be so far off, White House spokesman Scott McClellan said, “you have to be prepared for the unexpected, and you have to be flexible enough to adapt to circumstances on the ground. And it’s important that you give the commanders on the ground the flexibility they need to adapt to changing circumstances. And that’s what we will always do. That’s how you are able to succeed and complete the mission.”

As I’ve noted previously, this happens with every war. There’s nothing unexpected in things going not according to plan in war. There’s nothing unexpected in politicians underestimating costs by an order of magnitude as they make a hard sell for war (or whatever).

We’re near the halfway mark. Expect U.S. taxpayers to be on the hook for one half trillion dollars plus interest by the time the U.S. government declares victory, goes down to ignominious defeat, or otherwise winds down fighting in Iraq.

When an experienced programmer gives you an estimate on a routine software project, double the estimate. When a politician estimates the cost of a pet project, multiply by ten, then double that number (in order to be prepared for the unexpected).

Semantic Web Oligopsonies

Wednesday, January 12th, 2005

Google’s director of search quality bashes manual ontologies, with much justification.

However, his attempt to paint successful ontologies into a tiny niche doesn’t exactly work:

The best place where ontologies will work is when you have an oligarchy of consumers who can force the providers to play the game. Something like the auto parts industry, where the auto manufacturers can get together and say, “Everybody who wants to sell to us do this.” They can do that because there’s only a couple of them. In other industries, if there’s one major player, then they don’t want to play the game because they don’t want everybody else to catch up. And if there’s too many minor players, then it’s hard for them to get together.

Aren’t search engines and browsers in a sense oligopolistic (actually oligopsonistic) consumers of web content? There are only a few of each that matter anyway.

Barring interest from Google, Microsoft, Mozilla, and Yahoo! there may be oligopsonists (or monopsonists who want their standards adopted) in niches that can drive metadata adoption in their niches.

Infoanarchy, DRM and Celestial Jukebox

Monday, January 10th, 2005

On the brouhaha over Bill Gates’ interview with CNET at CES. The relevant bit:

[D]o you think intellectual-property laws need to be reformed?

No, I’d say that of the world’s economies, there’s more that believe in intellectual property today than ever. There are fewer communists in the world today than there were. There are some new modern-day sort of communists who want to get rid of the incentive for musicians and moviemakers and software makers under various guises. They don’t think that those incentives should exist.

And this debate will always be there. I’d be the first to say that the patent system can always be tuned–including the U.S. patent system. There are some goals to cap some reform elements. But the idea that the United States has led in creating companies, creating jobs, because we’ve had the best intellectual-property system–there’s no doubt about that in my mind, and when people say they want to be the most competitive economy, they’ve got to have the incentive system. Intellectual property is the incentive system for the products of the future.

The “communists” bit is the part that has gotten so many people worked up.

The Response. I enjoy calling out Gates’ idiocies as much as the next person, though much of the response I’ve seen has been a tad ebullient. Microsoft fans don’t create fascist art knockoffs when that company’s detractors incorrectly call it fascist. Glenn Otis Brown has the best response I’ve seen, posted on the Creative Commons weblog.

What Would Brezhnev Do? In a communist state would there be no financial incentives for artists? No, they’d simply be employed by the state. The Soviet Union took information control to extremes, including prohibiting use of photocopiers by scientists. I suspect that had the USSR survived to this day, the KGB would now be furiously trying to make Digital Restrictions Management work so as to gain access to a few of the wonders of computing without permitting open communication.

Advice to Gates. Call reformers anarchists rather than communists. For most people “anarchist” is derogatory and you wouldn’t be telling quite as much of a bald-faced lie.

The Real Issue. Forget labels. Gates’ substantial claim is that strong intellectual protectionism drives economic growth. Gates believes this. He isn’t simply shilling for MSFT’s latest strategy. It is on this point that Gates must be rebutted.

Apologies to you the reader and to Robert Nozick for this post’s overwrought title.

Year in Prediction Markets

Saturday, January 8th, 2005

Chris F. Masse offers his highlights of the past year in prediction markets. His list is long and informative. Go read it. I have a few quibbles:

Biggest Winner/Loser of 2004. I agree with Masse’s picks (Winner: TradeSports, Loser: NewsFutures), but not his focus on the U.S. presidential election. TradeSports became the premier service for placing non-sports real money bets (despite offering only a small number of semi-interesting contracts) and the authoratative citation for market odds. NewsFutures launched with a fair amount of hype but always struck me as less than serious.

Destined for Stardom and Most Under-Reported Story. Masse says HedgeStreet and their CFTC approval. Last month I glanced at their home price hedgelets, which seemed too short term (one quarter? — I’m interested in betting on housing market “fundamentals” but not on short term movements) and very thinly traded. I don’t know anything about the company, but I wish them well. They’re hiring software engineers. I wonder if successful use of information markets inside corporations during the last year will come to light. That would be my bet for both destiny and under-reported categories.

Biggest Waste of Money. Not Andrew Tanenbaum‘s supposed $3000 expenditure on setting up a poll tracking site. If Masse knows how to create a top 1000 website for less than $3000 I hope he lets us in on the secret. Prediction markets did outperform polls, though I suspect Masse’s motivation for this anti-award is dislike of Tanenbaum’s politics. By the way, Tanenbaum didn’t teach Linus Torvalds computer science, as Masse claims, though Tanenbaum did give Torvalds a virtual ‘F’ in a 1992 Usenet debate.

Best Idea of 2004. I think Wolfers’ and Zitzewitz’s idea is backwards. I don’t care much about how events influence elections (useful information for campaign consultants). I do care about how elections influence events (useful information for voters).

Masse’s prediction markets portal has scads of interesting links. Presently missing is zMarket: An Open-Source Platform for Developing Decentralized Markets, which could be an interesting development for 2005.

Deployment Matters

Thursday, December 30th, 2004

Most popular descriptions of why BitTorrent works so well are off the mark, The BitTorrent Effect in the current Wired Magazine included. Excerpts:

The problem with P2P file-sharing networks like Kazaa, he reasoned, is that uploading and downloading do not happen at equal speeds. Broadband providers allow their users to download at superfast rates, but let them upload only very slowly, creating a bottleneck: If two peers try to swap a compressed copy of Meet the Fokkers – say, 700 megs – the recipient will receive at a speedy 1.5 megs a second, but the sender will be uploading at maybe one-tenth of that rate.

Paradoxically, BitTorrent’s architecture means that the more popular the file is the faster it downloads – because more people are pitching in. Better yet, it’s a virtuous cycle. Users download and share at the same time; as soon as someone receives even a single piece of Fokkers, his computer immediately begins offering it to others. The more files you’re willing to share, the faster any individual torrent downloads to your computer. This prevents people from leeching, a classic P2P problem in which too many people download files and refuse to upload, creating a drain on the system. “Give and ye shall receive” became Cohen’s motto, which he printed on T-shirts and sold to supporters.

Sites like Kazaa and Morpheus are slow because they suffer from supply bottlenecks. Even if many users on the network have the same file, swapping is restricted to one uploader and downloader at a time.

Most home and many business broadband connections are asymmetric — the downstream pipe is much fatter than the upstream pipe. That’s a problem any net application that requires significant upstream bandwidth has to contend with. There is no protocol solution. A BitTorrent client can’t upload any faster than a Gnutella client.

Kazaa, eDonkey and various Gnutella clients (e.g., LimeWire) have incorporated multisource/swarming downloads for three years, and the latter two also use partial file sharing (I’m not sure about Kazaa and PFS). These two key features — download from multiple peers, and begin uploading parts of a file before you’ve completed downloading — don’t set BitTorrent apart, though it may be slightly ahead in pushing the state of the art (I haven’t examined the protocols side by side).

So why does BitTorrent work so well? Deployment.

Gnutella et al users start a client and typically download and share files in one or more local directories. All files a user has collected are shared simultaneously. A client connects to random peers and accepts random queries and requests to download any files the client is sharing. There are significant refinements, e.g., ultrapeers and supernodes.) Downloads will be spread across a huge number of files and peers downloading the same file won’t necessarily know about each other (and thus won’t be able to upload to each other while downloading). Again, there are significant refinements — Gnutella peers maintain a list of other peers sharing a given file — knows as an alternate location download mesh.

For BitTorrent such refinements are superfluous. A BitTorrent user finds a “torrent” for a file the user wants to download, a BitTorrent client is launched and connects to a tracker specified by the torrent. All clients connecting to a tracker via a single torrent are by definition all downloading the same file, and they know about each other — the ideal situation for swarming distribution. And here’s the key to BitTorrent’s success in spite of typically limited upload rates: Because users are sharing only one or a few files — the one(s) they’re downloading — their precious upstream bandwidth is used to enhance a virtuous cycle in which everyone downloading the same file downloads faster.

This ideal situation also allows BitTorrent to utilize tit-for-tat (PDF) leech resistance — “Give and ye shall receive” above. A typical filesharing client can’t effectively use this strategy as it is unlikely to have multiple interactions with the same peer, let alone simultaneous mutually beneficial interactions.

There are technologies (possibly Distributed Hash Tables), tweaks (a client giving preference to uploads of files the client has recently downloaded has been proposed) and practices (encourage filesharing client users to initiate downloads from editorially controlled lists of files rather than via ad hoc peer searches) that can be implemented in typical filesharing clients to make the average user’s download experience better, perhaps someday approaching the average BitTorrent user’s experience when downloading a popular file.

There’s also lots of talk about decentralizing BitTorrent. See eXeem, supposedly to be released in a few weeks. It appears that eXeem will attempt to keep BitTorrent’s beneficial characteristics by limiting files shared to those a user has obtained or created a .torrent file for — perhaps similar to a hypothetical Gnutella client that only shared files for which it had alternate sources. I don’t have high hopes for the decentralized bits of eXeem, whatever they turn out to be. It may serve as a decent standard BitTorrent client, but there’s no need for another of those, and eXeem will supposedly be riddled with spyware.

Individual Rights Management

Wednesday, December 29th, 2004

Cory Doctorow correctly lambastes those soft on DRM for the umpteenth time. The following excerpt sparked a thought:

DRM isn’t protection from piracy. DRM is protection from competition.

Reminds me of airport “security” and similar. In the essay IDs and the illusion of security Bruce Schneier makes a case (not nearly as forcefully as can be done) that

Identification and profiling don’t provide very good security, and they do so at an enormous cost.

I’d argue that most measures justified by “security” actually make us less secure, in part because of their enormous cost. Another time.

Anyway, I think there’s a nice (ugly) symmetry in the arguments of apologists for Digital Restrictions Management and the national security state. Both are really much about restricting competition.

Lexus, Mercedes, Porsche

Wednesday, December 29th, 2004

Tyler Cowen cites a Harper’s Index factoid:

Number of American five-year-olds named Lexus: 353

One of them works at Raisins, featured in the first South Park episode I ever watched and still my sentimental favorite. Every kid should watch this episode. If it is available on DVD I can’t find it, but search for “South Park 714” or “South Park Raisins” on any filesharing network — South Park episodes are among the most shared content.

Also see Christian Hard Rock, which tackles filesharing. Almost every episode is well worth watching for kids and adults. Skip the movie, it sucks ass.
