If you were fretting about the Ubuntu mirrors being so slow, remember that the installer defaults to using HTTP, rather than FTP.

Adobe Opens Flash 9 Specification (Updated)

As part of Adobe’s OpenScreen project to get Flash onto more devices they have just openly published the Flash 9 specification, with what appear to be no restrictions on their part (that I can see). The OpenScreen site seems to confirm it, listing their moves as:

  • Removing restrictions on use of the SWF and FLV/F4V specifications
  • Publishing the device porting layer APIs for Adobe Flash Player
  • Publishing the Adobe Flash® Cast™ protocol and the AMF protocol for robust data services
  • Removing licensing fees – making next major releases of Adobe Flash Player and Adobe AIR for devices free

This is great news, suddenly Flash becomes an open standard and the projects to create open source viewers for it suddenly should have a lot of the information that they need. It doesn’t remove all the issues though, some of the codecs that can be employed are patented and can themselves attract licensing fees, but it does appear that they are not required (unlike OOXML, which requires MP3 for audio content for example). It also means that people wanting to implement open tools to create Flash content, or export to Flash, will have their job made a lot easier too.

Hats off to Adobe - better late than never!

Update: This also includes the FLV/F4V specification too!

Country Fire Authority gets RSS

The Victorian Country Fire Authority (CFA), the volunteer fire brigade that covers most of rural Australia and a lot of suburban Melbourne, now has an RSS feed for the incidents that they’re dealing with.

Very handy for keeping an eye on what’s going on. Be even nicer if you could get an RSS feed per CFA region, rather than just the entire state!

So Jeff Waugh has announced the “Australian Open Source Industry & Community Report” has been published as a PDF1, hopefully the first of many.

Come and see what Open Source really does for Australia!

Our conservative projection of earnings suggests that the Open Source industry generates $500 million in revenue each year, with over 50% of that being directly related to Open Source.

The report is covered by a CC license:

The Australian Open Source Industry & Community Report is published as a freely downloadable PDF on the Census project website and is redistributable under a Creative Commons Attribution-NoDerivatives license.

Mac.com email sillyness

You’d have thought Apple would know how to do email right, but sadly it appears not. A message I sent to the Beowulf list today generated a bounce from a mac.com email address back to me rather than to the envelope sender - very naughty as RFC-2821 says:

If an SMTP server has accepted the task of relaying the mail and later finds that the destination is incorrect or that the mail cannot be delivered for some other reason, then it MUST construct an “undeliverable mail” notification message and send it to the originator of the undeliverable mail (as indicated by the reverse-path).

I wonder if they read their Postmaster email ?

Courtesy of the Library of Congress blog it appears that everyones favourite US government agency, the Transportation Security Administration (TSA), has a blog of their very own where they try and explain what they do, and why…

You’ve got to feel sorry for the poor soul who has to moderate all the comments there!

Library of Congress photos on Flickr

On a similar theme to Google offering to host open source scientific data, the US Library of Congress has announced on its blog1 a project that has published over 3,000 photos from the LoC archives and seems to be going down a storm with Flickr users!

This is a pilot for what seems to be a larger Flickr initiative, which the LoC describes thus:

We’re also very excited that, as part of this pilot, Flickr has created a new publication model for publicly held photographic collections called “The Commons.” Flickr hopes—as do we—that the project will eventually capture the imagination and involvement of other public institutions, as well.

The LoC is also pretty sharp about the potential power of this, and how it may benefit themselves (and future generations), saying:

The real magic comes when the power of the Flickr community takes over. We want people to tag, comment and make notes on the images, just like any other Flickr photo, which will benefit not only the community but also the collections themselves. For instance, many photos are missing key caption information such as where the photo was taken and who is pictured. If such information is collected via Flickr members, it can potentially enhance the quality of the bibliographic records for the images.

This potential is foreshadowed by the discovery of 3 previously misidentified images of Abraham Lincoln’s second commemoration by a user of their traditional archive!

A user of our Prints and Photographs Online Catalog raised questions about the images, which sent Library of Congress curator Carol Marie Johnson sleuthing. Careful comparisons to the only other two known images from that event and meticulous combing through records led her to this discovery. My point is that if we can uncover those kinds of treasures, thanks in part to our discerning Web users, imagine what might happen after setting loose hoards of eager photo fans at Flickr.

This is why preserving our information for future generations is such an important activity, and why projects such as the National Archives of Australia push to develop open source Digital Preservation software tools is vital to ensure that our descendants have a rich picture of their history as we have of our ancestors.

Google to host Open Source scientific data sets

Now this sounds really interesting..

Sources at Google have disclosed that the humble domain, http://research.google.com, will soon provide a home for terabytes of open-source scientific datasets. The storage will be free to scientists and access to the data will be free for all.

They may also provide data viz tools..

Building on the company’s acquisition of the data visualization technology, Trendalyzer, from the oft-lauded, TED presenting Gapminder team, Google will also be offering algorithms for the examination and probing of the information.

There is more information (including about why Google intend to import data by shipping RAID arrays around the world) here and (more up to date) here.

We live in exciting times!
