Tilt-shift miniaturization in Gimp

Thursday, January 15th, 2009

In the last week, I’ve seen posts on BoingBoing and my friend Nick Whitaker’s blog about the Tilt-Shift Maker website, which will manipulate photos you upload to make them look like they were taken with a perspective-control lens.  Which got me wondering whether you can do the same thing in Gimp, GNU’s free image manipulation software.  Of course you can, and the basic technique is really easy.  This great post by the Flickr user shygantic in the Tilt-shift Miniature Fakes group explains it all.

My first tilt-shift miniature made in Gimp:

Tilt-shift photo of boats at Le Cabin Scott

The source photo was maybe not the ideal candidate because the field is too deep, but it’s a first try on the first photo I picked, which I think demonstrates how easy Gimp makes this.

Calm down, Matt Asay

Tuesday, October 7th, 2008

Matt Asay today springs to the defense of the widows and orphans over at Google and their comprehensive prosecution of the Google Chrome trademark. Google sent a DMCA notice to the developer of ChromePlugins.org, demanding he stop using their logos and a remix of their adorable comic, and the developer was understandably upset. Asay’s enthusiasm for Google’s cause is characteristic of his business-first approach to the Business of Open Source (though one wonders if he’s confused Google’s duty to police its trademarks for his own), but his high-handed tone is uncalled-for and his conclusions, though brief, are rife with oversimplification.

Asay responds to a rather balanced account of the enforcement with a volley of fake quotes attributed to god-knows-who: open source means “open to pilfer trademarks” and is “a stick-in-the-eye to ‘The (IP) Man’” and that all related rights are “up for grabs.” He bids the unidentified “some” people espousing these non-quotes, “pay attention… you’re wrong.”

The substance1 of Asay’s argument is a familiar truism: open source copyright licenses are instruments of copyright law. And as he says, “without copyright there is no copyleft.” But the implication that free and open source software depends upon copyright law (and this must be the implication or there is no point at all) is wrong (and doubly wrong because he italicizes it). Were copyright abolished and the default reset to “no rights reserved,” it would be a trivial matter indeed to allow others to modify my source code — I wouldn’t even need a license, because I would have no right to exclude.  It’s true that under a no-copyright regime, copyleft would break — I couldn’t use my right to exclude to compel others to make available source code they build on top of mine. But copyleft was devised in response to copyright, not in affirmation of it. In the GNU Manifesto which launched GNU and eventually the FSF, rms’s stated goal was to combat the increasing proprietarization of software. If software could not be made proprietary, copyleft may have been unnecessary. Of course, a company could still attain a sort of de facto proprietarization by controlling access to their source, but this would be much less effective under a system that didn’t punish reverse engineering or the use of decompiled or leaked source code.

Maybe abolition of copyright isn’t the answer, but copyright (much less in its present captive state2) is certainly not the only means to software freedom. And the mere existense of exclusive rights, even if similar rights are used to beneficial ends, is no justification for anti-social behavior, whether Google’s or Asay’s.

  1. And here more credible claimants to the title “substance,” such as plastic and cocaine, will forgive my lax usage. []
  2. My colleague Bradley Kuhn, who has said all of this before, has proposed a regime under which registrants of a copyright in software are required to deposit the entire source and in exchange are given 3 years of exclusive rights to it, after which their code becomes public domain. While not the only solution, or a universally agreeable one, it’s certainly imaginable. []

I wrote a post for SFLC’s blog, responding to a Law.com article on FOSS licensing:

Law.com recently ran a sensationalist piece by Edmund J. Walsh warning of the impending “dangerous real world business dispute” in store for any for-profit company that uses free software. Walsh points to lawsuits filed by SFLC on behalf BusyBox as a source of this danger, and having worked on those lawsuits, I hope I can provide a helpful counterpoint.
