Variations on an Open Source Theme

One of the most extraordinary - and under-recognised - developments in free software is the blossoming of specialist software applications.

Once, a common jibe was that the only programs available were for hackers. This made the appearance of the GIMP, an ambitious image manipulation program aiming to rival Photoshop, such an important milestone.

Since, then, of course, more and more programs have appeared for the most amazingly specialist areas. Here's another one:

Indiana University today announces the release of open source software to create a digital music library system. The software, called Variations, provides online access to streaming audio and scanned score images in support of teaching, learning, and research.

Variations enables institutions such as college and university libraries and music schools to digitize audio and score materials from their own collections, provide those materials to their students and faculty in an interactive online environment, and respect intellectual property rights.

...

This open source release of Variations complements IU’s earlier release of the open source Variations Audio Timeliner, which lets users identify relationships in passages of music, annotate their findings, and play back the results with simple point-and-click navigation. This tool is also included as a feature of the complete Variations system.

gIMP My Foot

Jackboot Jacqui is at it again:

The government Interception Modernisation Programme (gIMP), a plan by spy chiefs to centrally collect details of every phone call, text, email and web browsing session of every UK resident, will be in place by 2012, according to a Home Office minister.

Apparently:

because communications providers already hold information about who contacts whom, when and how, the gIMP would not represent a major change. "We are not proposing that data that have never been collected are held," he said. "The question is how in the future, with all the changes that are coming we can still have access to something that we regularly use today for serious crime and counterterrorism." The final system will be fully compatible with human rights legislation, he said.

This shows once again that the Government either doesn't understand - or feigns not to understand - that putting together disparate information *is* a huge change, precisely because it allows all kinds of *new* info to be gathered about the public thanks to correlations and cross-linkings that are not evident when the data is held separately. Crudely speaking, this is putting together the pieces of a jigsaw puzzle to see something whole.

Respect, Nathive

In the world of closed-source software, it's hard to get a project going in a sector with established players. Since everything must be built from scratch - no building on the work of others *here* - it requires considerable financial backing.

Of course, that's not the case with free software, where the archetypal person in a bedroom can just start hacking for the sheer love of it - like this, for example:

Unfortunately I do not have much help... in fact I'm not a Gnu/Linux Expert, I'm not a superstar programmer, Simply one day I promised myself to do this, life is something strange... Born in 1985, like FSF, I became Gnu/Linux user in 2007 (never too late) and this is my first C program. I love to learn!

I would like to form a working group and continue learning more and more quickly.

The project is Nathive:

Nathive is a libre software image editor, similar to Adobe Photoshop, Corel Photo-Paint or The GIMP, but focusing on usability, logic and provide a smooth learning curve for everyone. The project run over Gnome desktop and everyone can colaborate in it with code, translations or ideas.

The project is in alpha phase, so it is an incomplete work, the intention is to achieve progressively a professional graphic editor without giving up the initial usability. It's a made from scratch code, with C programming language and GTK+, simple, lightweight, easy to install and use.

I particularly liked the first statement of the following:

Nathive Philosophy

* Show respect and gratitude to GIMP community.
* First make it easy, then make it powerfull.
* The user don't need to see every options all time.
* If it seems absolutely absurd, might work.
* Everything should be obvious.

Respect and gratitude begets the same.... Good luck, Nathive.

Pre-installed Software: A Better Way

PC BOX BUILDERS are thinking of getting rid of the tradition of stuffing your new PC or laptop with trial software that you don’t really want anyway.

The reason is that some retailers, such as Best Buy, are making a small fortune removing the software and charging punters for the privilege.

Well, how about this: instead of loading PCs with a load of junk that users pay to be removed, why not put on a few, good open source programs: OpenOffice.org, Audacity, the Gimp, Blender? No cost to the manufacturer, no rubbish for the end user. Just a thought....

Sage Does the Maths of Free Software

One of the persistent myths about free software is that successes like Linux are one-offs, and that the open source methodology can't be applied easily to tackle complex software challenges. In the early days of free software, the relative paucity of end-user apps was trotted out as proof of this idea - The GIMP stood in splendid isolation back then.

Things have change, though; today, there is a wide range of high-quality open source apps, and the list keeps on growing. Here's there latest, and it's a biggie:

Until recently, a student solving a calculus problem, a physicist modeling a galaxy or a mathematician studying a complex equation had to use powerful computer programs that cost hundreds or thousands of dollars. But an open-source tool based at the University of Washington won first prize in the scientific software division of Les Trophées du Libre, an international competition for free software.

The tool, called Sage, faced initial skepticism from the mathematics and education communities.

"I've had a surprisingly large number of people tell me that something like Sage couldn't be done -- that it just wasn't possible," said William Stein, associate professor of mathematics and lead developer of the tool. "I'm hearing that less now."

Open-source software, which distributes programs and all their underlying code for free, is increasingly used in everyday applications. Firefox, Linux and Open Office are well-known examples.

But until recently, nobody had done the same for the everyday tools used in mathematics. Over the past three years, more than a hundred mathematicians from around the world have worked with Stein to build a user-friendly tool that combines powerful number-crunching with new features, such as collaborative online worksheets.

"A lot of people said: 'Wow, I've been waiting forever for something like this,'" Stein said. "People are excited about it."

Sage can take the place of commercial software commonly used in mathematics education, in large government laboratories and in math-intensive research. The program can do anything from mapping a 12-dimensional object to calculating rainfall patterns under global warming.

The benefits of using free software for maths extend far beyond the usual ones:

The frustrations weren't only financial. Commercial programs don't always reveal how the calculations are performed. This means that other mathematicians can't scrutinize the code to see how a computer-based calculation arrived at a result.

"Not being able to check the code of a computer-based calculation is like not publishing proofs for a mathematical theorem," Stein said. "It's ludicrous."

Beyond the gPhone: the gPC

On Thursday, WalMart begins selling the Everex Green gPC TC2502, a $198, low-power, Linux-based PC designed primarily for running Web 2.0 applications.

When users first fire up their gPC, they'll get a Mac-like desktop with a series of program icons "docked" across the bottom. The icons are bookmarks to popular and useful Web 2.0 services from Google and other vendors. There are icons for Google Docs, Gmail, Google Maps, and YouTube, for example, as well as Meebo, Facebook, and Wikipedia. Sprinkled into the lineup are some non-Web-based apps, like Skype and Gimp, but the novice user won't know, initially, which are local applications and which are Web services.

There are two really interesting things here.

One, of course is the price, which would be impossible with Microsoft Windows. The second is the way the manufacturer is trying to create a machine whose software is based around Web apps. One important aspect of this approach is that it decouples user software from the underlying operating system. So the fact that this machine is running GNU/Linux is almost at the level of what BIOS it uses.

As Google fills out its SaaS vision, so we can expect more of these extremely lean machines, for equally lean prices - and increasingly lean times for Microsoft.

Update: Apparently, this is on older Windows machine, but with a leaner OS. Why?

“Windows Vista has its own market, but it’s not on the $200 end. Those experiences aren’t good. Our Vista Basic units were selling well at $498, but it was the highest return rate ever, because the client was so heavy” and overwhelmed the hardware capabilities. To Kim, the message is Windows needs the power of a premium machine.

And as The Innovator's Dilemma teaches us, the premium market is *always* cannabalised by the cheaper models as they gain more capabilities for the same cost.

Portuguese Ministry of Education Goes Free

The Portuguese Ministry of Education is doing the sensible thing and giving away a CD full of free (Windows) software to 1.6 million students, saving itself (and the taxpayers) around 300 million Euros. Nothing amazing about that, perhaps, since it's a sensible thing to do (not that everyone does it).

What's more interesting, for me, at least, is the set of software included on the CD:

* OpenOffice.org
* Firefox
* Thunderbird
* NVU
* Inkscape
* GIMP

These are pretty much the cream of the free software world, and show the increasing depths of desktop apps. Also interesting are the specifically educational programs included:

* Freemind and CmapTools
* Celestia
* Geogebra
* JMOL
* Modellus

Some of these were new to me, notably Geogebra:

GeoGebra is a free and multi-platform dynamic mathematics software for schools that joins geometry, algebra and calculus.

and Modellus (which isn't actually free software, just free):

Modellus enables students and teachers (high school and college) to use mathematics to create or explore models interactively.

It's always surprised me that that more use isn't made of free software in education, since the benefits are obvious: by pooling efforts, duplication is eliminated, and the quality of tools improved. (Via Erwin Tenhumberg.)

OpenProj

For many years, the only decent free end-user app was GIMP, and the history of open source on the desktop has been one of gradually filling major holes - office suite, browser, email etc. - to bring it up to the level of proprietary offerings.

Happily, things have moved on, and it's now possible to use free software for practically any desktop activity. One major lack has been project planning, traditionally the (expensive) realm of Microsoft Project. No longer it seems. With the launch of OpenProj, the open source world now has a free alternative, for a variety of platforms.

It's still too early to say how capable the program is, but it's certainly a welcome addition. The only other concern is the licence, which seems not to have been chosen yet, although an OSI-approved variant is promised.

Update: Apparently, if I'd taken the trouble to install it, I would have seen that the licence is the Common Public Attribution Licence. (Thanks to Randy Metcalfe.)

Spreading Spread Firefox

Most computer users by now have heard of the Firefox browser. This is hardly surprising given the extraordinary rate at which it is still being downloaded and diffused around the world well over a year since its formal launch.

Given that there have now been nearly 150 million downloads (converting that into a meaningful number of users is probably impossible), it is only natural that people think of Firefox as an incredibly successful free browser. It is that, certainly, but it is also much more.

After all, the open source community has shown time and again it can write great code: Linux, Apache, The GIMP, OpenOffice.org - choose your own favourite. But Firefox has done something else - something that has never been done before by a free software project.

It has translated the secret of open source's power - a huge, distributed and connected development team - into the sphere of marketing. The Spread Firefox site has mobilised tens of thousands of users - not as beta testers, as has been the custom previously, but as a guerrilla marketing force.

Most famously, that force was mobilised to pay for the double-page ad in The New York Times. Through the aggregation of many relatively small donations it was able to take out some high-price advertising. In other words, the approach scales.

But the real achievement of Spread Firefox is much subtler, and more diffuse. The tens - hundreds? - of thousands of active Firefox supporters are Microsoft's worst nightmare: a completely invisible - because distributed - team of product evangelists that it can never hope to pin down, let alone match.

This is such an important step beyond the traditional open source process that it is tragic not more has been done with it. For example, although there is a Spread OpenOffice.org, it is only now that a Spread KDE site has been created; both seem in their early stages. But where are all the others? Where are Spread Linux, Spread Thunderbird, Spread GIMP, Spread Audacity and the rest?

All these programs have enthusiastic users who could be directly mobilised across the Internet to spread the word about how good these applications are. Relying on old-fashioned, uncoordinated word-of-mouth is simply to throw away everything that has been learned from Spread Firefox - and to discard one of the strongest trumps in the free software hand.
