Opera About Walt Disney Refused Permission To Use Disney Images

Techdirt has noted before the hypocrisy of Disney in refusing to allow others to draw on its creativity in the same way that it has drawn on the art and ideas of the past. Here's another example, but this time it's an opera that's had difficulties:

Behold Opera Unite: the Anti-Cloud

I have a soft spot for Opera. I've always been a fan of this plucky underdog, ploughing its own furrow, and doing all the other metaphors that are invoked in these cases. I even like its product - pity it's not open source....

Do Open Source Eyeballs Really Work?

One of the most contentious areas in computing is whether open source is more or less secure than closed source systems. Open source is open for everyone – including the black hats – to poke around and find the bugs, but it's also open for anyone skilled enough to fix them. Closed source is (theoretically) harder to peek into, but (practically) impossible to fix unless you work for the company that wrote it.

Here's some nice empirical evidence that many eyeballs looking at open source code *do* make a difference...

Why Javascript, not Flash? - Ask Zoho

I've only just come across this, perhaps the best summary of why using Flash is the wrong way to create Web apps:

1. Native to the Web

A real web application should natively support web standards - HTML & CSS are pretty much synonymous with “web standards”. The biggest reason we started out with Javascript is that it is native to the web - in the sense its core object model for Javascript is the HTML/CSS Document Object Model. The DOM is a gift to web applications. Even with the annoying browser differences in DOM (which sophisticated libraries increasingly hide), it is still far better to have the DOM than not have it. Flash, for all its advantages, sits in a separate space from the browser. In that sense, Flash is not that different from Java-on-the-client. In fact, Flash is Java-on-the-client-done-right.

I am sure Flash will eventually find a way to natively integrate with the browser but it is not there yet.

2. Open Source Library Support

This is a big one. The depth and variety of libraries available in Javascript just keep getting better. It is mind boggling just how much open source development is going on in Javascript. Developers keep pushing the envelope. For one example, look at the jQuery solar system demo. It shocked me the first time I saw it. Pretty impressive that Javascript could do that, right? The capabilities of Javascript exceed the client requirements of office productivity applications today, and there are tons more innovations coming.

3. Vector Graphics in Browsers

This is another big one. Vector graphics formats like SVG (Firefox, Opera), VML (IE), and HTML Canvas (Firefox, Safari, Opera), are becoming ubiquitous in browsers. Yeah, it sucks that IE doesn’t support SVG, but that can be worked around. Even cooler is the fact that SVG & VML are XML and very Javascript friendly. You can do real magic.

Obviously, number 2 is the heart of the matter: Javascript is just going to keep getting better, faster, thanks to the open development process. With Flash, you're dependent on the skills of one company (now, where have I heard that before?)

Carmen, the Blog

Further proof, if any were needed, that blogs have entered the mainstream:

When the curtain falls on the final performance of English National Opera’s Carmen on Friday it will also end a groundbreaking experiment in connecting artists with their audience.

The production, staged by the film director Sally Potter, has been a commercial hit but was mauled by the critics, who called it “woefully tedious”, “an ugly, misbegotten aberration” and “a suicide note to the Arts Council”.

However, through a series of blogs written by members of the cast and crew, including Potter, the ENO believes it defused some of the power of the reviews by reaching out to the paying public.

Is Silverlight for GNU/Linux Moonshine?

Hm, don't know what to think about this:

Over the last few months we've been working to enable Silverlight support on Linux, and today we are announcing a formal partnership with Novell to provide a great Silverlight implementation for Linux. Microsoft will be delivering Silverlight Media Codecs for Linux, and Novell will be building a 100% compatible Silverlight runtime implementation called "Moonlight".

Moonlight will run on all Linux distributions, and support FireFox, Konqueror, and Opera browsers. Moonlight will support both the JavaScript programming model available in Silverlight 1.0, as well as the full .NET programming model we will enable in Silverlight 1.1.

I suppose it depends on how open the specification is - and whether it's just OOXML by any other name....

Anyone any thoughts?

Welcome Back, HTML

Younger readers of this blog probably don't remember the golden cyber-age known as Dotcom 1.0, but one of its characteristics was the constant upgrading of the basic HTML specification. And then, in 1999, at HTML4, it stopped, as everyone got excited about XML (remember XML?).

It's been a long time coming, but at last we have HTML5, AKA Web Applications 1.0. Here's a good intro to the subject:

Development of Hypertext Markup Language (HTML) stopped in 1999 with HTML 4. The World Wide Web Consortium (W3C) focused its efforts on changing the underlying syntax of HTML from Standard Generalized Markup Language (SGML) to Extensible Markup Language (XML), as well as completely new markup languages like Scalable Vector Graphics (SVG), XForms, and MathML. Browser vendors focused on browser features like tabs and Rich Site Summary (RSS) readers. Web designers started learning Cascading Style Sheets (CSS) and the JavaScript™ language to build their own applications on top of the existing frameworks using Asynchronous JavaScript + XML (Ajax). But HTML itself grew hardly at all in the next eight years.

Recently, the beast came back to life. Three major browser vendors—Apple, Opera, and the Mozilla Foundation—came together as the Web Hypertext Application Technology Working Group (WhatWG) to develop an updated and upgraded version of classic HTML. More recently, the W3C took note of these developments and started its own next-generation HTML effort with many of the same members. Eventually, the two efforts will likely be merged. Although many details remain to be argued over, the outlines of the next version of HTML are becoming clear.

This new version of HTML—usually called HTML 5, although it also goes under the name Web Applications 1.0—would be instantly recognizable to a Web designer frozen in ice in 1999 and thawed today.

Welcome back, HTML, we've missed you.

Google's Gears of War

Gears is a browser extension that we hope -- with time and plenty of input and collaboration from outside of Google -- can make not just our applications but everyone's applications work offline.

Well, not exactly gears of war, not least because Google has wisely made the code freely available under an open source licence:

We are releasing Gears as an open source project and we are working with Adobe, Mozilla and Opera and other industry partners to make sure that Gears is the right solution for everyone.

But certainly likely to represent the start of a skirmish or two in the field of offline working.

It Ain't Over Until Blake Ross Sings

There are three names that most people would associate with Firefox. Ben Goodger, who works for Google, and whose blog is pretty quiet these days. Asa Dotzler, who has a articulate and bulging blog. And then there's Blake Ross, also with a lively blog, but probably better known for being the cover-boy of Wired when it featured Firefox.

Given his background - and the immense knock-on effect his Firefox work has had - Ross is always worth listening to. That's particularly the case for this long interview, because it's conducted for the Opera Watch blog, which lends it both a technological depth and a subtle undercurrent of friendly competition:

I think Opera is better geared toward advanced users out of the box, whereas Firefox is tailored to mainstream users by default and relies on its extension model to cater to an advanced audience. However, I see both browsers naturally drifting toward the middle. Firefox is growing more advanced as the mainstream becomes Web-savvier, and I see Opera scaling back its interface, since it started from the other end of the spectrum.

Wolfgang Amadeus Mozart, Hacker

Today is the 250th anniversary of the birth of Wolfgang Amadeus Mozart. Most people know him as one of the world's greatest composers: a child prodigy, creator of over 600 works, and – if you believe some of the wilder rumours - fatally poisoned at the age of 35 by a rival composer. Few, though, are aware that Mozart was also a hacker.

Computers may not have existed in the eighteenth century, but the musical machines called orchestras and choirs are conceptually identical to synthesisers, which are themselves specialised music computers. Just as programming code specifies how a computer should act (and a MIDI file controls a synthesiser), so musical code – in the form of a score – directs what instruments and voices should do and when.

Conductors are largely superfluous in all this (at least for Mozart's music): they do not create the output, which is specified by the score. All they do is interact with the score “loaded” on the orchestral or choral machine, in the same sense that someone might interact with a video game loaded on a console. The incidental nature of humans in the performance of classical music is shown by some pieces that Mozart wrote at the end of his life for a clock with built-in mechanical organ. Here the scores completely determined the audio output: there was no human intervention once the music had been converted to a kind of piano roll – a forerunner of the punch cards employed a century and a half later by the early commercial mainframe computers.

More generally, though, hacking is a state of mind, a way of understanding and exploring the world, independent of a particular technology (and not to be confused with “cracking”, which is the correct name for the kind of digital smash and grab too often in today's headlines). Richard Stallman, perhaps the greatest hacker of modern times, has defined the essence of hacking as “playful cleverness” - as good an encapsulation of Mozart's genius as any.

The cleverness showed itself early. Mozart started learning the piano when he was three, began composing when he was five, and wrote his first symphony and opera at the age of eight and 11 respectively. Like many top coders, he frequently worked out everything in his head before consigning it to paper at a single sitting (often just hours before a deadline – again, just like some programmers), and usually without the need for revisions (that is, bug-free). He could also multi-task: he is supposed to have written one of his finest works during a game of skittles.

Like any red-blooded hacker, Mozart adored mathematics as a child (and gambling as an adult), found word-play irresistible (email would have been perfect for him) and loved setting himself puzzles. His Musical dice game uses dice throws and pre-composed short fragments of music to form compositions created by random numbers; the challenge was writing fragments that would fit together whatever the throws. At one point in his opera Don Giovanni, in addition to the main orchestra accompanying the singers, there are three more orchestras on stage, each playing completely different music. It all fits together so perfectly that most opera lovers are unaware of the compositional tour-de-force they are witnessing.

Mozart's playfulness was a key facet of his character. The musical form he seems to have enjoyed writing most – opera buffa – is simply Italian for “funny opera”. In several concertos composed for a horn-playing friend, Mozart added jocular comments to the music - “Slowly, Mr Donkey”; “Breathe!”; “Go on!”; “Oh, filthy swine!” - an early example of commented code. He sometimes employed different coloured inks in a score, rather as modern programming tools do to differentiate various elements. Another piece, called A musical joke, includes notes that are blatantly wrong. If the musicians play them as written, they sound incompetent; if they play the “right” notes, they have failed to perform the piece as the composer intended, and so are indeed incompetent.

Significantly, Mozart was a big fan of a key hacking concept known as recursion, whereby something refers to itself to create a kind of infinite loop. For example, a core hacking project started and led by Stallman is called “GNU”, an acronym for “GNU's Not Unix”, which uses itself in its own explanation. (Recursion is another example of playful cleverness).

Recursive music is created by employing a delayed version of a tune as its own accompaniment. Formally, this is known as a “canon” (simpler versions, like the song “London's burning”, are called “rounds”), and Mozart wrote dozens of them, mostly for himself and his friends to sing at purely private performances. They are notable not only for their fine music, but also for the texts Mozart chose to set: “Lick my bum” is one memorable line that crops up more than once. Today's hackers, too, enjoy dubious lyrics, and have an earthy turn of phrase: the injunction “RTFM” - often thrown at hapless newbies - does not stand for “Read The Flipping Manual”.

Another notable characteristic of hackers is their fondness for science fiction. Overt references to Star Wars may be thin on the ground in Mozart's works, but many of his operas written in the older, “serious” style are based on the same eternal themes of good versus evil and love versus duty that lie at the heart of George Lucas's epic.

The science-fiction writer Arthur C. Clarke once suggested that any sufficiently-advanced technology is indistinguishable from magic; the corollary is that magic is indistinguishable from sufficiently-advanced technology. So Mozart's last opera, The Magic Flute - full of other magical objects, too - is, from this viewpoint, a work of science fiction. It is also a Masonic opera, steeped in mysterious symbols and rituals that will be nonetheless be familiar to the hackers who participate in MMORPGs (Massively Multiplayer Online Role-Playing Games), where characters join guilds, complete quests and seek to gain experience points - just like the hero in The Magic Flute.

The close links between music and hacking run both ways, and many of today's top coders are highly musical. Richard Stallman – whose dedication to the cause of freedom is positively Beethovenian - carries with him a soprano recorder wherever he travels. The profoundly-religious and frighteningly-cerebral Donald Knuth – a kind of hacker J.S.Bach - was moved by his love of music to have an 812-pipe baroque organ built in a specially-designed room in his house. Appropriately enough, Knuth's life-work is called The Art of Computer Programming (Bach called his The Art of Fugue). Representing a different musical tradition, Brian Behlendorf, the prime mover behind the Apache Web server program that runs two-thirds of the Internet, DJs ambient and dub music. And it is well known that for most hackers the crucial first step when they start working is to fire up some particularly loud and inspirational music on their computer. Mozart would have approved.

Firefox 2.0

I commented earlier on how Firefox's market share seems to be soaring; clearly the organisation is beginning to gain some serious momentum in the market. However, Internet Explorer 7.0 is slouching towards Redmond to be born, and will finally offer features that have been available from Firefox and Opera for some time. Potentially this could stunt further growth for the open source browser, and even pull back some of its market share.

The news that Firefox 2.0 is well on its way shows that the Mozilla organisation and Firefox coders are well aware of the threat. Releasing 2.0 so soon will keep the pressure up on Microsoft, and those share figures rising, one hopes.
