Mahara: Who'd Have Thought?

One of the things that warms the cockles of my heart is the widening ripple of open source. Starting, as it did, with core system software, it is now moving ever further into more specialised areas. Take Mahara, for example:

an open source e-portfolio system with a flexible display framework. Mahara, meaning 'think' or 'thought' in Te Reo Māori, is user centred environment with a permissions framework that enables different views of an e-portfolio to be easily managed. Mahara also features a weblog, resume builder and social networking system, connecting users and creating online learner communities.

This is part of the power of free software: however good it is today, it will be *even* better tomorrow, because old programs are never discontinued (even if they are no longer actively supported).

Don't you just love monotonicity?

ACTA's Acts of Stupidity

Alongside the UK's Tom Watson, New Zealand's Clare Curran is shaping up as one of the leading net-savvy politicians in the world. Here's a typically clueful post about ACTA and her country's role in the negotiations, concluding:

Why are law-makers heading down this route? It flies in the face of reality. What lies behind the Digital Economy Bill and ACTA?

The best thing the NZ Govt could do is to release its negotiating position to its citizens. Let’s all be in this discussion. Transparency is by far the best policy.

Indeed. But also worth noting is this wonderful point made by Colin Jackson in the comments to that post (pointed out by Curran herself):

What a pity international governments don’t seem to be able to make an agreement to ration finite resources like tuna, atmospheric carbon or fossil fuels, but instead devote their time to making an international agreement enforcing controls over something that costs no resources to copy.

Beautifully put.

What Lies at the Heart of "Avatar"?

If nothing else, "Avatar" is a computational tour-de-force. Here are some details of the kit they used:

It takes a lot of data center horsepower to create the stunning visual effects behind blockbuster movies such as King Kong, X-Men, the Lord of the Rings trilogy and most recently, James Cameron’s $230 million Avatar. Tucked away in Wellington, New Zealand are the facilities where visual effects company Weta Digital renders the imaginary landscapes of Middle Earth and Pandora at a campus of studios, production facilities, soundstages and a purpose-built data center.

...

The Weta data center got a major hardware refresh and redesign in 2008 and now uses more than 4,000 HP BL2×220c blades (new BL2×220c G6 blades announced last month), 10 Gigabit Ethernet networking gear from Foundry and storage from BluArc and NetApp. The system now occupies spot 193 through 197 in the Top 500 list of the most powerful supercomputers.

Here's info about Weta from the Top500 site:

Oh, look: Linux. Why am I not surprised...?

DNA Database Breached in New Zealand

Yesterday, I wrote about how the UK ID database has been breached even before it formally exists; now here's another tale that shows what the problem with all such super-duper databases is:

Police are investigating a claim an Environmental Science and Research worker made an "inappropriate disclosure" from the DNA databank.

ESR said yesterday a criminal investigation had started. "A staff member has been suspended pending the outcome of the police and internal investigations," a spokeswoman said.

Which means that *every* database, ultimately, has a weak link: people. So all these assurances of cast-iron, unbreakable security are worthless, for the simple reason that these databases are designed to be used by people, not all of whom are trustworthy or unblackmailable....

ACTA's Unspeakable Acts

Since neither the EU nor the UK government has deigned to let us peasants know anything about the current ACTA negotations, I was interested to see New Zealand's government releasing a statement, which contained the following:

Participants agreed to continue consulting with stakeholders through domestic processes, share the results of these consultations at their next meeting, and to continue exploring opportunities for stakeholder consultations in connection with future ACTA meetings.

Ah, right; but I don't suppose the stakeholders in those "domestic processes" include mugs like you and me, do they?

Microsoft's OOXML Dirty Tricks, Part 78594

Sigh:

We have discovered that Matthew Holloway was badly slurred by a Microsoft employee in an email to one of the bodies advising an overseas standards NB. It is worth noting that our own national body, Standards New Zealand (SNZ), took the claims so seriously that they responded to parties who received this email.

We discovered the slur by chance, similar information may be circulating in other countries. If you are aware of this please point concerned parties to this article. SNZ have given us permission to quote this email. I have removed names to protect the guilty parties.

And Micosoft wonders why it is so hated.... (Via Groklaw.)

Oh, Tell Me the Truth about OOXML

The ODF vs. OOXML battle is really hotting up - a sure sign that this is important. One of the key issues is whether OOXML can ever be fully implemented by anyone else other than Microsoft: if it can't, then it can hardly be called a true open standard. Here's some analysis that suggest is can't. Not that will stop it becoming one....

From the Commons to...Managed Parks?

One of the areas where the commons is being increasingly invoked is that of radio spectrum, the idea being that there can be frequencies "held in common" for the benefit of all. WiFi is a good example, and more and more jurisdictions are looking to create spectrum commons of one kind or another in order to encourage innovation with the minimum of regulation.

But here's an interesting twist from New Zealand, which is considering creating both "public parks" and "managed parks" for radio spectrum:

A "public park" is analogous to common land, with complete freedom of entry balanced by a requirement that users do not interfere with the activities of other licensees. In New Zealand, limits and conditions of use are defined by a General User Licence (GUL). A common condition of use is operation on a non-interference basis which means that a (General User Radio Licence) GURL licensee shall not cause interference to, nor claim protection from, other licensed services. As a result, issues of interference are normally resolved between users, as a matter of common interest.

"Public parks" can be used for a variety of other purposes including, for example, security detectors, cordless phones, radio-controlled devices, medical monitors and RFID labels. It is possible that, at a local level, this may continue to be a satisfactory environment for some broadband service providers.

...

The Ministry has also been considering combining the advantages of the "public park" with features of the spectrum licence, by establishing "Managed Parks". If "public park" spectrum is analogous to common land, then the Managed Park is akin to a publicly-owned sports ground, in that there is a gate-keeper, consent is required to gain admission and users can engage only in the activities for which the facility is provided.

Aren't metaphors a wonderful thing? (Via Openspectrum.info.)
