Some 118 different police agencies from across Canada came to the Vancouver area as part of the $900 million 2010 Olympics security effort.  The RCMP sent over 4000 officers from provinces across Canada; various municipal police departments sent some 1700 more.  (20% of Canada’s policing power was at the Olympics.) I figured it would be fun to say hello to a constable from every one of those agencies. I didn’t get to them all, but it was fun trying.

Our family network includes a Samba file server hosted on an NSLU2 server appliance by Linksys (now a part of Cisco). A long time ago we changed to the Unslung open firmware for the NSLU2 (or “Slug”, as we call it).    It’s a wonderful combination, powered by a rich assortment of free software created by many volunteers. I appreciate their efforts.

But two years ago, I moved my personal computing from a laptop running Mac OS X 10.3 to one running Mac OS X 10.5. On the new 10.5 laptop, I noticed that the NSLU2 failed to respect file modification times. That is, if I had a file created on Dec 1, 2007 on my laptop, and I dragged it to a Samba volume hosted on the NSLU2, then the time stamp on the copied file was changed to the present time. The Dec 1, 2007 modtime was lost. Similarly, if I used touch -t from the Mac OS X command line to change the timestamp on a file hosted on the NSLU2 Samba volume, the operation failed. If I tried  sudo touch -t, that succeeded, just until another client viewed the file — at which point the timestamp snapped to the present again. However, if I copied a file resident on the NSLU2 Samba volume to another location on the volume, the timestamp was preserved.

Urban British Columbia in general, and the Vancouver metro area in particular, has thriving technology and social media communities.  (There’s industry in there somewhere, also.) This community exists in part through face-to-face relationships, and in part on-line. Through this community, you can meet interesting people, learn what is happening in the industry, network for job leads, and of course have a good time.

There’s nothing terribly unusual about the techniques for plugging into this community as opposed to any other. But here is my advice for specific starting points.

Basic Identity and Persona

The first thing to have is an identity, a way for people to refer to you and link to you. From this identity you will grow an online persona.

Q: What sorts of copyright changes do you believe would best foster competition and investment in Canada?

A: Three changes:

1. relinquish Crown Copyright
2. create legal structures for free culture, and industries based on it
3. don’t take on the job of defending obsolete business models

I use the wonderful Exact Audio Copy (EAC) software to rip my CDs to FLAC files, as part of moving our music collection onto a media server.  I had just uninstalled version 0.99pb3 (this thing has been “pre-beta” and version 0.99 for years!) and installed version 0.99pb5. I set the directory to which EAC writes its extracted files to be on my Samba file server. When I tried 0.99pb5, though, I observed that whenever I tried to copy tracks from the CD, an “Error Message” alert box would pop up, saying “File Creation Error !” What I expected, and what I recalled from using 0.99pb3, was that EAC would write the compressed files happily to the server directory.

The minimal test case to produce the error was to select one track from the CD, and then select the menu item “Action“… “Copy selected tracks” “Uncompressed“. The Windows system in question is a virtual machine running Windows XP on my Macbook Pro laptop.  I had set up EAC’s “Standard directory for extraction” to a UNC server path, let’s call it “\\samba\media\Music\untagged_flac\“.  I observed, by the way, that when I changed the destination directory to be something on my Windows C:\ drive, then EAC wrote the file with no problem. And interestingly, EAC had no trouble writing log files and cue files to the server directory using the UNC path, but it refused to write audio data files.

The workaround which succeeded for me was to map a drive letter to the UNC path. In my case, I mapped the letter “Z:\” to “\\samba\media\Music\“. Then, I set EAC’s “Standard directory for extraction” (under “EAC“… “EAC options“… “Directories” tab…) to “Z:\untagged_flac\“.  Then EAC happily wrote compressed music files to my network directory.

I think this write failure is a regression from 0.99pb3; I recall the UNC path working then. But I haven’t reinstalled 0.99pb3 to prove the point. If you try that experiment, please leave me a comment and tell me what you found.

There are other possible causes for the “File Creation Error !” alert box.  A couple I found were:

• Unpermitted leading “\” character in EAC’s “naming scheme” option (under “Filename” tab), per a hydrogenaudio thread “EAC: File Creation Error on first CD track”
• Filename or total file path too long (I don’t know the operative limit), per a hydrogenaudio thread “EAC pb5 directory problem causes File Creation Error”

May no-one else have to spend the time I spent diagnosing this problem! Happy exact audio copying!

P.S. my thanks to the developers of EAC, and of FLAC.exe, and all the other pieces of software in this marvelous free tool chain.

Q: Based on Canadian values and interests, how should copyright changes be made in order to withstand the test of time?

A: The largest single dynamic is the change in delivery of cultural works from physical containers (paper books, CD disks, celluloid film) to digital information (ebooks, music files, computer networks).

Physical containers are:

1. either immediately accessible by humans (books), or accessible via limited machines which did not copy the container.
2. expensive to duplicate, and expensive to transport. (more…)

We’re experimenting with what format will serve us well. For this month’s meeting, I’ll give a talk about staging servers (details below) and we’ll have plenty of time for networking and Q&A. I there there’s lots of room for more Joomla content in this town. Here’s the coordinates:

They asked for submissions addressing five topics.  Here’s one of my submissions, on “Copyright and you“. It’s hard to tell what will become of these consultations, because the government may fall (again) before Parliament gets a chance to pass a new bill. My submission may eventually show up on the official submissions page. Until then, here it is, for the record.  I have two more submissions which I’ll dribble out in the coming days.

   Q: How do Canada’s copyright laws affect you? How should existing laws be modernized?

   A: This topic should not just be about copyright, it should also be about culture. I absorb culture, some of it through copyrighted works, some through public domain or non-copyrighted works. I also create works: essays, blog posts, musical performances, even submissions to government consultations. Thus I am *both* a producer and a consumer.

   All culture is built by mixing and innovating based on previous culture. Disney’s “Sleeping Beauty” was based on German folks tales written down a few centuries before.

   The purpose of copyright is to strike a balance: to allow a limited right to prevent copying, in exchange for a larger social and cultural good. In today’s Canada, this balance has been greatly distorted, in favour of the publisher and the corporation, against the vast majority of artists, against the public, and against the culture. Digital technology, extra-long copyright terms, and aggressive policies by industry groups mean that publishers have greatly expanded their power to prevent copying. The public interest and the culture are harmed.

But I’m using Mac OS X, I get my code through Macports, and Django’s instructions don’t quite cover this case.  So I just figured it out.  Here’s the tricks I needed.  Maybe it will help you.
