Sneak preview of my new web framework Michaelangelo

I’ve been working on a new web framework which provides image theming – a little like what Elegant Grunge does with its image frames, but much more sophisticated.

For example:

This is a PHP framework that uses the common GD library to manipulate images.

It’s main interface is a content filter – give it HTML, containing images, and it will return the same HTML modified so that the images are now the converted versions, according to their ‘class’ attributes, with appropriate width/height attributes, etc. This makes it super easy to work with.

It stands alone, but it is also going to be a WordPress plugin (as you can see on this site, it’s already operational), a Joomla plugin, and I’m considering establishing a web service too, so those who don’t have adequate software on their server can still use it.

It has a plugin-based architecture so anyone can add new ‘themes’ (props to my partner Katherine for that beautiful wooden frame, by the way). I’m going to also implement a simple XML-based plugin schema, and possibly an interface to it, so that it’s easy to do so. I’m planning a ‘community’ style directory site to host contributed styles.

The base frame rendering code is such that it is trivially easy to add a new ‘theme’. It extracts segments from a single frame image, and handles seamless tiling to make the frame the right dimensions, so you don’t even have to worry about overlapping regions.

I will release it soon, after adding a little more content – keep your eyes peeled.

For now, check out the Michaelangelo showcase, which gives an idea of the different styles, and contains an interactive sampler to play with styles (IE users should stop being IE users to view this).

Doing my bit to beautify the web.

Align comments in Textmate

Unless I’m using Objective-C, which is fantastically self-documenting, I often like to add comments to parameters to remind me of what they do. For example:

imagecopy($image, $frame, 
          ($x=max($width-$this->topRightCap[kCapWidth], $this->topLeftCap[kCapWidth])), // Destination x
          0,  // Destination y
          $x,  // Source x
          0,  // Source y
          min($this->topRightCap[kCapWidth], $width-$this->topLeftCap[kCapWidth]),  // Source width
          $this->topRightCap[kCapHeight]); // Source height

The only thing is, it looks terrible and is very hard to read. I usually carefully insert spaces before the comments so they line up, but that’s really hard to maintain.

I use [Textmate](http://macromates.com/), and found an ‘Align Assignments’ script by Chris Poirier which applies very nice formatting to a block of assignments.

Some trivial modifications resulted in a similar script to align comments. Hit Ctrl-Option-Command-/, and:

imagecopy($image, $frame, 
          ($x=max($width-$this->topRightCap[kCapWidth], $this->topLeftCap[kCapWidth])), // Destination x
          0,                                                                            // Destination y
          $x,                                                                           // Source x
          0,                                                                            // Source y
          min($this->topRightCap[kCapWidth], $width-$this->topLeftCap[kCapWidth]),      // Source width
          $this->topRightCap[kCapHeight]);                                              // Source height

Mandatory internet filtering in Australia

This is copied from an email I recently sent out to everyone in my address book

Mandatory internet filtering – I actually thought this issue was over with, but it appears I was wrong.

If you’re not already aware of the issue (which is probably unlikely), there’s a [factsheet from GetUp](http://tinyurl.com/5l6ktm)

The latest news here is that the secret blacklist (which is secret – Freedom of Information laws have been [modified](http://tinyurl.com/6k574h) to deny any kind of public oversight) has been leaked, and contains all kinds of nasty stuff, but also a fair amount of relatively benign stuff: “a slew of online poker sites, YouTube links, regular gay and straight porn sites, Wikipedia entries, euthanasia sites, websites of fringe religions such as satanic sites, fetish sites, Christian sites, the website of a tour operator and even a Queensland dentist.” [The Age](http://tinyurl.com/ccqzpt)

The general concern is that this would be a secret, unaccountable system, a ‘loaded gun’ that could too-easily be subverted (Thailand’s internet content was originally intended just to filter out child pornography, but is now apparently used to [silence sites](http://tinyurl.com/ccqzpt) that criticise the royal family). [No western democracy](http://tinyurl.com/5l6ktm) has gone down this path before. Already it has been reported that there’s very little accountability to the blacklist administration process (“They have absolutely no review process whatsoever; the decision to ban content is final, and there is no judicial oversight. The decision is made by a single ACMA staffer, even someone part of a graduate process…” [The Age](http://tinyurl.com/dyofpc))

That’s the worst of it – there’re other issues about the filter raising the cost of Internet access, and slowing down the Internet ‘up to 87%’.

GetUp has a petition in progress – I recommend that you [sign it](http://www.getup.org.au/campaign/SaveTheNet), if you feel so inclined:

If you’re as angry about this stuff as I am, I recommend writing a letter to Senator Conroy, as well (I wrote [this one](http://atastypixel.com/2008/12/02/email-to-senator-conroy-about-proposed-internet-content-filter/)). His email address is [[email protected]](mailto:[email protected]).

[Wikileaks](http://wikileaks.com/), the website set up to hold documents submitted anonymously by whistleblowers, has apparently been brought to its knees by the huge number of requests from people looking at the leaked blacklist. Does anyone else find it hilarious that the very content the government has been trying to censor has now had a huge spotlight focused on it? Oh, man…

The [summary](http://www.wikileaks.com/wiki/Australian_government_secret_ACMA_internet_censorship_blacklist%2C_6_Aug_2008) on the Wikileaks page regarding the ACMA’s blacklist is worth a read, too. “…History shows that secret censorship systems, whatever their original intent, are invariably corrupted into anti-democratic behavior.”

AutoRate 1.5.0 beta

After a long hiatus, it’s time for a new version of AutoRate!

AutoRate 1.5.0 introduces a new, more sophisticated rating formula, thanks to the fantastic efforts of Brandon Mol (read about his changes [here](http://tzisoftware.com/forum/index.php/topic,85.0.html)). It’s still currently in beta, until it can be confidently dubbed bug free.

Download the AutoRate 1.5.0 beta over at the [Google Code project](http://code.google.com/p/autorate/downloads/list).

Update: Beta 2 now available, which fixes a bug with the min/max rating setting.

Finder toolbar scripts for better workflow

I recently found two Finder toolbar scripts which are really going to make my life easier.

The first one, Open In TextMate, will open either the current folder, or the selected item(s), in TextMate.

The second, Open Terminal Here (and icon modification), will open a Terminal window at the current path.

The US Digital Millenium Copyright Act

This was a paper I wrote for the third year of my Computer Science bachelor degree in 2004. It’s obviously relatively old now, but the DMCA still exists and I thought I might post it here – researching the paper was how I was introduced to the DMCA, and I was reminded of it when posting the previous article on a new Swedish law

With the advent of the ‘information age’, unauthorised reproduction of copyrighted works has become far easier. The tools to reproduce such material in any desired form are freely available, as are tools to distribute this material to others all over the world. Piracy is commonplace, with use of interned-based file sharing systems such as Kazaa and eDonkey becoming vastly widespread. 2003 revealed software piracy losses of $341 million AUD in Australia, and $6,496 million AUD in the United States (Australian Institute of Criminology).

In an environment where, feasibly, only one individual needs to purchase a copy of a work to enable the whole world to gain access, various industries – such as the music, film and software industries – are growing increasingly concerned.

An international treaty drafted by the World Intellectual Property Organisation (WIPO), defined a requirement that participating parties “provide adequate legal protection and effective legal remedies against the circumvention of effective technological measures that are used by authors in connection with the exercise of their rights under this Treaty…” (WIPO Copyright Treaty, Article 11). In order to implement this requirement, the Digital Millennium Copyright Act (DMCA) was signed into U.S. law on October 28, 1998.

The controversial act, labeled by some as unconstitutional and a threat to public liberty and free speech, states that “No person shall circumvent a technological protection measure that effectively controls access to a (protected work)” (DMCA, Section 103). It constitutes a protection of software that restricts access to copyrighted material, and outlaws any effort to circumvent this software.

Since coming into effect, the DMCA has been frequently drawn upon for purposes outside of the original expected scope of the Act. In several instances, it has been used by companies to suppress the publication of research into security flaws in their products. Prominent security and cryptology researchers are now choosing to leave their fields out of fear of the DMCA, and security conferences are leaving the U.S. for safer countries.

The DMCA has been used by Sony to maintain a monopoly over production of Playstation console games, Adobe and the U.S. Government have attacked a Russian company for writing software that enables eBooks to be read on braille displays, and a student has been taken to court after submitting a post online explaining that holding down the Shift key disables copy protection on some audio CD’s.

Contrary to the expectations of Congress, the DMCA, as stated by the Electronic Frontier Foundation, “Chills free expression and scientific research”, “jeopardizes fair use”, and “impedes competition and innovation” (EFF, ‘Five Years under the DMCA’).

New Swedish IPRED big-content lovin’ law: “Totally Fking Batst Insane”

Jesper of Waffle Software writes on a directive (the IPRED EU directive) written into Swedish law recently that gives ‘rights holders’, provided that they can display ‘cursory evidence’, powers well above those of any governmental agency. Paraphrasing from Jesper’s comments, if Big Content suspects you of having involvement in copyright infringement activities (downloading from BitTorrent, etc.), they can:

Start a private criminal investigation against you
Force your ISP to release your personal information (although there’s no guarantee that an IP address associated with the activities in question directly relates to your activity)
Freeze your bank account and seize your home (allowing them to search the premises)
Threaten you with court action unless you pay a tens-of-thousand-USD fine
Take you to court “where you’ll have to prove your innocence without a lawyer by your side since you can’t afford one, because they froze your bank account”
Collect their enormous damages, and charge you for the legal fees

Read the full article, and the preceding introduction for more.

Jesper outlines some specific nasties about the IPRED EU directive, but essentially we’re at least looking at a breach of “several human rights, including the rights to privacy and due process”. We’ve had some pretty nasty laws thrust upon us in the name of Big Content recently, but this one is absolutely insane. How far are governments going to go with this? I’m reminded of the Mars series by Kim Stanley Robinson, set in the future, where countries and governments are more-or-less irrelevant, and the real powers are the big ‘multinationals’, immense international corporations who have sweeping powers, including their own militaries.

If this law actually remains in place, and is used, it will be very interesting to see what happens. As my partner Katherine commented, surely a citizen looking down the barrel of this baby can take the matter to the EU, citing human rights infringement – assuming Sweden has signed a human rights convention.
