Sunstone


A very determined group of researchers has found an example of the previously legendary Viking sunstone used for navigating while the sun was obscured by clouds or below the horizon.  The best and most concise article I've seen is this one at The Economist.  If there were a Nobel Prize for Archeology, this team would win it.

Circular Logic at Wikipedia

An amusing first for Wikipedia:
"Germany has a new minister of economic affairs. Mr. von und zu Guttenberg is descended from an old and noble lineage, so his official name is very long: Karl Theodor Maria Nikolaus Johann Jacob Philipp Franz Joseph Sylvester Freiherr von und zu Guttenberg. When first there were rumors that he would be appointed to the post, someone changed his Wikipedia entry and added the name 'Wilhelm,' so Wikipedia stated his full name as: Karl Theodor Maria Nikolaus Johann Jacob Philipp Wilhelm Franz Joseph Sylvester Freiherr von und zu Guttenberg. What resulted from this edit points up a big problem for our information society (in German; Google translation). The German and international press picked up the wrong name from Wikipedia — including well-known newspapers, Internet sites, and TV news such as spiegel.de, Bild, heute.de, TAZ, or Süddeutsche Zeitung. In the meantime, the change on Wikipedia was reverted, with a request for proof of the name. The proof was quickly found. On spiegel.de an article cites Mr. von und zu Guttenberg using his 'full name'; however, while the quote might have been real, the full name seems to have been looked up on Wikipedia while the false edit was in place. So the circle was closed: Wikipedia states a false fact, a reputable media outlet copies the false fact, and this outlet is then used as the source to prove the false fact to Wikipedia."


via Slashdot - full discussion here.

I'm posting this for amusement, not to criticize Wikipedia.  My take-away is that there are lazy reporters who don't properly check their facts (what a surprise), and that someone caught the inaccuracy almost immediately.

WW2


Nicholas Bradbury with the gadget, Alamogordo New Mexico, July 1945.

The gadget was the bomb fired at the Trinity test, July 16, 1945.  The photo must have been taken on the 14th or 15 as the bomb has been hoisted into the tower.  It seems likely that Bradbury (who was in charge of the gadget) wouldn't stop for a photo until he was finished, so this is likely from the evening of the 15th.  The test took place before sunrise on the 16th.

The gadget was the first plutonium implosion bomb, and another like it was dropped on Nagasaki in August.  The Hiroshima bomb was a much more primitive Uranium gun-type bomb.  It was considered so reliable that it didn't need testing.  The implosion bomb, by contrast was extremely complex.  Inside the case is more than a ton of specially formulated high explosive designed to crush an orange-sized ball of plutonium to criticality.  The charges need to be perfectly shaped and fitted, then exploded simultaneously or it won't work.  By simultaneously, I mean within within all the charges needed to be fired within some millionths of a second.  Thus the complex wiring and need for a test.

WW2

A ponderous pre-war Soviet bomber.  This kind of plane didn't stand a chance against decent fighters or flak guns.  Neither the Russians, nor the Japanese, nor the Germans were able to field a credible strategic bomber during the war.  The British had two, the Americans four.  As a result, Japanese and German cities were reduced to rubble.  During the entire war, the Luftwaffe managed to kill about 90,000 British civilians.  By 1945, Allied bombing was killing more German civilians than that each week.  The Americans killed more Japanese civilians than that in a single raid, several times.

On the Eastern Front, air superiority was always a local issue.  The front was simply too big to gain anything more than a local advantage.  The only exception to this was the pre-emptive strikes carried out by the Germans on June 22, 1941.  However, the Red Air Force was useless at that point, and wouldn't have been able to slow the Wehrmacht much anyway.  In all, air power never had the decisive impact in Russia that it had in the West.

The Intellectual Property War: A Turn of The Tide?

      Captain Copyright, From a ludicrous and short-lived pro-copyright campaign by the Canadian version of the RIAA - Yes this is real
Two developments in the US legal system last week may indicate a turn of the tide in the Intellectual Property (IP) wars.  The first was a significant Federal Court ruling limits what can be patented and invalidates thousands of questionable existing patents.  The second was a novel and very persuasive constitutional challenge to the Recording Industry Association of America (RIAA) lawsuit campaign against individual file sharers.  As they play out, these two events should mark a significant change in the legal landscape for IP world-wide.

When it comes to IP law, the US leads the world.  This is due to several factors.  First, the US is by far the biggest exporter of IP.  Second, the technology that has changed the nature of IP mostly origionated in the US.  Until recently, US internet traffic has been greater than the rest of the world combined.  Third, Americans tend to settle things through litigation rather than legislation.  So there is always lots of action on the IP front.  Lastly, IP is one of the fault lines in the macro development of the post-national world.  Briefly, the nation state is becoming obsolete due to globalization.   The nation state will not disapear, but it is evolving.  There are two competing models to replace it: the EU regional state approach, and the American corporate state approach.   IP is a key point of conflict because it represents the tension between corporate and public ownership.  Companies want to extend their control over products past the point where consumers make the purchase.  Consumers want the opposite (which is ok) and whatever they can get for free via digital distribution (less ok).  The ideal world for content creators is when the consumer pays every time they access a particular peice of content.  They want content to stay live and open-ended (licensed like software) rather than dead and purchased like a book.  The stakes are immense in terms of revenue.  But technology so far has trumped the political and legal weapons of content owners.

There are three types of intellectual property under US law, and each is rife with litigation.  Trademarks are commercial property and give a company a monopoly on the use of a term in a particular business.  I can't start a computer company called Apple.  But I can start a tire company called Apple.  Apple has trademarked the term for use in the computer business.  This is a sensible law that protects both companies and consumers from fraud by third parties.  Unfortunately, trademark is now widely used by companies trying to surpress use of names outside their industry, or by people saying things about the company that they don't like.  For example, Monster Cables routinely sues anyone that starts any business in the US with "monster" in the name.  The test for a trademark infringement is the "idiot in a hurry".  Would an idiot in a hurry think your company A is really company B with a similar name?  Or would an idiot in a hurry think your effort that mentions company B is actually sanctioned by company B?  If so, you are probably infringing.  But real trademark infringements are rare, usually restricted to counterfeiters deliberately trying to fool consumers.

Patents are the second type of IP protected by US law.  Patents are a time-limited monopoly on the design of devices.  Patents are specific and require detailed description.  You can't patent an idea.  The law has traditionally required devices to be 1) novel, and 2) non-obvious before they can be patented.  Patents are granted by a government agency, the Patent Office.  One must apply for a patent, providing all the relevant paperwork and support material.  A patent examiner goes through the application and either grants or denies the patent.  The process is supposed to be difficult because a patent amounts to a government enforced monopoly.  Monopolies are good for monopolists, but bad for the public.  That's why monopolies like the gas company are heavily regulated.  The rationale for patents is that a limited-time monopoly is necessary to encourage the resources needed to invent new technology.  Most countries have a very similar regime to the US.

Unfortunately, several things happened to distort US patents.  The first was creation of a special court to deal with patent cases.  This should have been a good thing, but it didn't work out that way.  Some questionable rulings were made, and because the patent court had limited oversight by the rest of the judicial branch, it was difficult to challenge these.  Second, one of these rulings was that patents could be granted out not only for devices, but for methods.  This ruling allowed patents on software, algorithms, genes and other intangibles.  Lastly, the US patent office was underfunded and unable to deal with the flood of patent applications created by the methods ruling.  Examiners lacked the expertise to deal with software and the time to look for prior art.  So they just granted most applications and let the courts sort out which ones were correct.  The result was chaos.  It is now widely accepted that the US patent system has broken to the detriment of economic performance.  There are so many dubious patents that it is becoming difficult to bring new products to market.  It has happened before with the US aircraft industry.  It took WW2 to clear the logjam.

Techdirt summarizes last week's Federal Appeals court ruling on the original case that legitimized business concept patents:
The summary is that the court has said that there's a two-pronged test to determine whether a software of business method process patent is valid: (1) it is tied to a particular machine or apparatus, or (2) it transforms a particular article into a different state or thing. In other words, pure software or business method patents that are neither tied to a specific machine nor change something into a different state are not patentable.
Emphasis in original. This is an extremely important ruling.  Battles are currently raging in several countries, and the EU over software patents.  This ruling will take the wind out of the sails proponents.  A significant argument they were making was that local companies would be at a disadvantage if they could not patent things that were patentable in the US.  In addition, this should be the end of patent trolls.  Companies that buy up patents and sue everyone  making something even theoretically similar.  Patent law is remote from consumers, being something litigated between companies.  However, the number of dubious patents and the aggressiveness of patent holders in the courts has had an enormous impact on product development in the US. This chilling effect has not only retarded development in high-tech.  It has had a very dramatic impact in medical, pharmaceutical and biotechnology industries.

The last type of IP covered by US law is the most familiar.  Copyright is the limited ability for a content creator to control their creation.  It protects the expression of an idea.  A story about teenage wizards cannot be copyrighted.  A story about a teenage wizard named Harry Potter who attends a school called Hogwarts can.  When someone in the US downloads a song or a movie from the Internet, they are infringing copyright.  Note that copyright infringement and theft are not the same thing, despite their frequent conflation.  Theft deprives the owner of an object, copyright infringement does not.  Infringement denies the owner a sale, assuming that the infringer would have purchased the item had they been unable to acquire it illegally.  

Obviously, the Internet and digital file-formats have dramatically changed content distribution.    Remember when a copy of a copy of a videotape was lousy?  That was analogue, every digital copy is exactly the same as the original.  The Internet gives people the means to distribute these perfect copies between themselves.  The problem for content owners like music companies is that their business model is based on scarcity.  If you wanted a song, you had to buy a copy from the record company.  They were the only ones who had original high-quality content.  Now, everything is different.  Rather than adapt to the new situation, the US content industries tried to impose the existing business model on the new world.  They successfully lobbied for new IP laws and have used the power granted by these laws to prosecute individuals for infringement.  The RIAA has sued over 30,000 individuals in the US.  Most settle out of court for some thousands of dollars rather than incur the legal fees required to fight.  However, the legal basis for the RIAA's actions is questionable, as are the methods they use to acquire information on individuals they want to sue.  In cases that have gone to trial, the RIAA has lost all but one, and that ruling was subsequently put aside by the judge who declared a mistrial.   Many in the US legal community are unhappy with the way the RIAA has used the legal system as a bludgeon and look forward to a reckoning.

Apart from the legal problems, the RIAA's approach has been suicidal from a business point of view.  Not only have they had zero impact on the number of files being shared, but have covered themselves in negative publicity.  That negative publicity on its own has reduced their revenues and created enemies throughout the technology industry.  Two years ago, the RIAA switched tactics and began to sue Universities who failed to stop file sharing on their internal networks.  This was a promising avenue because students are big file sharers and Universities are unlikely to risk huge fines to protect them.  Unfortunately for the RIAA, they are as inept at law as they are at business.  Some Universities successfully fought back based on privacy concerns and the questionable tactics of the RIAA at collecting evidence.

Notable among high-profile schools, Harvard has never been sued.  This has occasioned comment.  The tech press speculated that the RIAA was afraid of their potential counter-attack.  They were right to be.  Harvard law professor Charles Nesson got tired of waiting and has intervened in an unrelated RIAA action against an individual, Joel Tannenbaum.  Nesson has made a novel and devastating constitutional challenge to the entire RIAA legal strategy.  The law gives the RIAA a statutory penalty much greater than the market price of the infringed music.  They can collect as much as $150,000 for a song that sells for $0.99 at the iTunes store.  Typically, they settle out of court for between $500 and $1500 per song.  The counter-argument Nesson advances is that the legislation enabling these suits is unconstitutional.  It amounts to a criminal law being run by a private entity for its own profit.
Imagine a statute which, in the name of deterrence, provides for a $750 fine for each mile-per-hour that a driver exceeds the speed limit, with the fine escalating to $150,000 per mile over the limit if the driver knew he or she was speeding. Imagine that the fines are not publicized, and most drivers do not know they exist. Imagine that enforcement of the fines is put in the hands of a private, self-interested police force, that has no political accountability, that can pursue any defendant it chooses at its own whim, that can accept or reject payoffs in exchange for not prosecuting the tickets, and that pockets for itself all payoffs and fines. Imagine that a significant percentage of these fines were never contested, regardless of whether they had merit, because the individuals being fined have limited financial resources and little idea of whether they can prevail in front of an objective judicial body.  
Yikes.  If you have any interest, its worth reading the whole thing.  Nesson goes on to eloquently demand compensation for Tannenbaum and others targeted by the RIAA based on their abuse of the courts.  That could amount to a half a billion dollars.  Not something the RIAA's money losing members would care to contemplate.  If successful, the argument would also derail the Motion Picture Association of America (MPAA) legal strategy.  The MPAA has been far more judicious in their use of the courts, but their aims have been similar.  Both met the Internet revolution with a counter-revolution via the Congress and the Courts.  This may be at an end.

Together, these two legal developments promise to revolutionize the landscape for IP law in the US.  Many fundamental legal issues remain to be settled, but we can hope that the tide is turning.

A Red Reality Check

After breathlessly reporting  on the game changing nature of the new Red One 4k digital camera, it only seems fair to report some caveats.  A bunch of rebuttals have been collected on the Red Facts page .
The key points are:
  • Red has fudged the resolution numbers.  The tech specs have been polished up by marketing so that an apparent apples to apples comparison with other cameras is misleading.
  • Extreme compression and interpolation produce noticable blocking and pixillation at full-screen projection.  35mm and high-end HD do not.
  • There is some resentment in the cinematographer community that Red is using the mainstream tech press to hype the product. 
I've worked in the industry and can attest the cinematographers are a finicky guild.  They don't like being talked down to and they really don't like being told what to use by a director that's fallen for some company's hype.

Fanboys are livid.  Accusations (probably true) that many of the Red Facts facts come from Panavision and/or Sony.  A classic flamewar is developing.  But who cares?

So Red may not be the revolution.  But if not, then someone else soon.  Canon and Nikon are very busy in this realm.  Red may yet have some tricks up its sleeve.

The only other interesting facet of this issue is the continuing marketization of previously non-tech industries.  Marketization is what happens when tech industry marketing and product standards infect non-tech industries. It is a cancerous sub-set of traditional marketing.  Beta products, fudged specs, bleeding edge features adopted across the board, personalization of competition, no guarantees, six month product cycles, complete disregard for customers of previous product cycles, engineered lack of interoperability, expectation of continuing customer upgrades at a pace dictated by the vendor, DRM, Windows Vista.  Its the selling of broken or crippled products as a matter of course.  Everything becomes disposable.  Anything you can't fix with a patch, you throw away.  Microsoft is the best example of this disease, but they didn't invent it and are no more responsible for it perpetuation that HP, IBM or Apple among many others.  Add Red to the list.

When Microsoft landed the huge and high profile London Stock Exchange account, it published the self-congratulatory ad below:



Yesterday, the exchange went down for 7 hours.  Innuendos aside, it was a bad day for an outtage.  Traders were fuming that they missed out on action related to the Fannie and Freddie takeovers.  Reuters quoted one: "We have the biggest takeover in the history of the known world ... and then we can't trade. It's terrible".

This just shows that public masturbation, while it may feel good at the time, is never a good idea.

This man is a brilliant genius.  He does vector renderings of military aircraft.  These two statements may seem contradictory.  I assure you the characterization is not made lightly. WS_Clave can somehow bring out the inner beauty of airplanes in a way that's rare to see in any type of technical illustration.  His illustrations remind me of Haeckel and other great nature illustrators from the 18th and 19th centuries.  Pages of F-16s in various colour schemes may not be your thing, but that doesn't lessen his achievement.  These pictures, to me at least, have the same magic stillness as Renaissance alter pieces.

Game Changer

When I first started photography in the mid-80's, the princes of the publishing world were the typesetters.  If something went into print, it had to be type set, and the princes would exact their toll.  They had money to burn and would ride around Yorkville in specially imported BMWs and Rolls.  Then Steve Jobs decided laser printers and Macs would be a killer combination for publishing.  He was right, and ten years later the type houses were gone.  Not only did people who were already spending money on type switch, lots of others who could never have afforded to became publishers.

The same thing is about to happen in the film business.  Making a cinema quality movie remains an extremely expensive enterprise.  The digital revolution has made movie making a mass market proposition, but professional quality has remained far out of reach.  The gold standard is 35mm film run through a professional movie camera. HD digital cameras are widely used for TV and some cinema productions.  But HD is nowhere near 35mm in terms of quality, and the cameras have limitations compared to traditional film cameras.

Red Digital Cinema surfaced two years ago with claims of a new digital movie camera that would hammer traditional movie technology.   They promised three revolutionary features.  A 35mm quality sensor, an ability to take standard movie camera lenses, and a price of less than 1/10th that of professional motion picture cameras.  According to a feature in Wired (watch the video), they have delivered all three.  The $17,500 4K Red One captures 4,096 x 2,304 pixels and takes off-the-shelf professional lenses.  That compares to 1,920 x 1,086 for a $150,000 HD camera that cannot take standard lenses.  Or to a standard 35mm movie camera from Panavision that rents for $25,000 a month and delivers in the region of 4K resolution.  Plus film, development and scanning.  This can be worth several hundred thousand dollars for a feature film.  The 4K outputs to hard drives.  And hard drives are cheap.    Its also smaller than an HD camera  and much, much smaller than a film camera.  Size and weight are important as they limit what can be done with the camera.  Shots using cranes, booms and helicopters are rare in all but the most expensive films due the cost of cranes, booms and helicopters.

This is apparently only the beginning.  Really epic films used to be shot in 70mm rather than 35mm.  That's about halfway between 35mm quality and Imax quality.  Unfortunately, the cost became so great that the last film shot entirely in 70mm was Ryan's Daughter in 1972.  The splendor and impact of such visual quality disappeared from movie making.  Red is promising a 5K camera next year.  Obviously, they can go further.  But even if that was all, 5,000 lines of resolution is better than anything since 70mm became uneconomic.

They are also promising a 3K camera next year.  Its incredibly small, can be controlled wirelessly, and will be cheaper yet I expect.  Still cameras are also under consideration.  High-end professional digital cameras cost upwards of $40,000.

All very interesting from a technology and cost point of view.  But there is an interesting asthetic promise as well.  Over the last 15 years, movies have used more and more digital effects.  Not only are they cheaper than the real thing, but can deliver scenes that could never be filmed at any price.  For example, the 250,000 strong Orc army in Return of the King.  A steadily larger slice of what we see on the screen is CGI.  Despite being a digital technology, Red holds the promise of making traditional film making techniques more cost-effective.  Unlike many at my end of the political spectrum, I believe technology is more liberating than dictatorial.  To paraphrase uh, someone, communication becomes democratic when the people control the means of production.  The artist in me is please also because digital has come to mean crap.  Crappy digital music, crappy digital pictures and crappy digital video.  Technologies like Red will hopefully change that.

Big Brother's Achilles Heel


The Plettenberg Bay Traffic Department (South Africa), sent a summons to the owner of the Volkswagen pictured above. The department's camera clearly shows the auto traveling faster than the 60km limit. Pretty much a slam-dunk conviction, you'd think. The photo and story came from The Daily WTF. There is a reproduction of the entire summons.

I really love this kind of thing, no sarcasm. Sometimes I worry about the emerging big brother systems in Europe and the USA. That some governments are keen to use massive computer systems for law enforcement and keeping order is no longer a paranoid fantasy. It is coming true. I don't think anything can be done to stop it. However, there is all the difference in the world between always-on monitoring and a repressive police state. Seriously.

Stalin was the perfect dictator, in the perfect storm sense. He didn't have computers, or CCTV, or biometrics. He didn't need them. Such technology would be useful, but is not necessary. Complete political control makes the structure of dictatorship. As long as those operating the CCTVs aren't required to belong to a particular political party, or have a commissar watching them, these systems are functionally useless to the dictator.

They can, obviously, be enabling if a dictator can gain control. But most dictatorships are really kleptocracies in disguise. Creation of a determined lack of accountability more often protects corruption than ideology. Compare China and North Korea. North Korea is a real, Stalinist, ego-driven dictatorship. China went through periods like that, but has degenerated into corruption. The leadership will allow anything that does not come between them, their personal financial opportunities, or the monopoly on power than creates those opportunities. Ideology doesn't come into it. That is why there are no more cultural revolutions or great leap forwards. That kind of ego-politics is bad for business.

During the Cold War, there was an ongoing debate about the inevitability of a Communist state producing a Stalin. Now we know the answer is no. What is inevitable is an East Germany or a China. Not because they are Communist, but because the leadership has no accountability.  These states get taken over by thieves who displace or co-opt the ideologues.  They become kleptocracies who's lifetime varies inversely to the greed of its leaders. The more restrained the leaders, the longer they can get away with it.

Which brings us back to technology. It doesn't work. Technology cannot produce dictatorship because technology is stupid. Corrupt, inefficient bureaucracies can't use technology to impose central control because they are corrupt and inefficient. Such systems, however, can enable petty tyranny very well. Just look at US airports. But the technology isn't a means of control in those situations. The technology is a means of corruption (through contracts) and way to protect the petty tyrants from accountability. The two always go together.

The venality, incompetence and rigidity of the would-be dictatorship makes a real big brother like monitoring regime impossible. In real life, the cameras are pointed the wrong way. The file systems are incompatible. The servers go down at critical moments. Turf wars prevent interoperability. Greed ensures that contracts go to vendors who's systems are crap.  The technology that ends up getting deployed is easily hacked.  The whole technology driven police state model doesn't work.

The traffic ticket at the top is an example that gives away the game. Its not about enforcing speed limits (control). Its about tax revenues for the government and revenue for the company contracted to run the system (greed). This can be petty dictatorship, but never the real thing.
