Doing my part in the Copyright fight

Michael Geist writes:

I’ve talked about the need for balanced copyright for many years, but we’ve never seen this much public engagement in copyright. That is because the real story is that copyright matters to people and they now have the tools to make their voices heard. I’m thrilled to have played a role in raising awareness, but the real credit goes to the thousands of people who took the time to write or call their elected representatives, to blog about the issue, to attend the Toronto or Calgary events, or to raise awareness with their friends, family and community.

I’ve been doing my part. On Monday night I sent a letter to my MP, James Moore, whom I talked to at his open house on Saturday. He said that he would pass on my concerns to the Minister of Industry. I’ve also managed to sign 16 people up to the Facebook group.

Heatwave!

Wow, it was hot last night! So hot, I had to shut down the PVR:

Message from syslogd@ebi at Wed Jul 11 18:39:42 2007 …
ebi kernel: CPU0: Temperature above threshold

It seems like my plants are doing ok. There is a danger of the tomatoes dropping their blossoms before fruit has formed, but I don’t think that has happened.

And on a blogging note, there aren’t many times that I can have a post that’s in both the MythTV and Gardening categories!

B.C. swelters under record highs

Seven all-time temperature highs were set across British Columbia on Wednesday, with most of the records falling in the Fraser Valley, the Greater Vancouver area and on Vancouver Island.

Paid EMIs from Amazon EC2

New feature from Amazon EC2:

Paid AMIs allow AWS developers to charge other Amazon EC2 users for the use of AMIs they have created and shared. Sellers of AMIs set the price, and their customers then purchase one or more AMIs and are billed through Amazon.com for their use of these paid AMIs.

Right now, only a select group of people can create paid AMIs, but hopefully they will open it up to more in the future.

Drupal Presentation

Thanks to everyone who came out to the presentation tonight.

I’ve put the presentation online if you want to download it. Hosted by S3, natch. :)

Teenagers pwned by Facebook

Kids these days!

Police use Facebook to douse party plans

Ontario Provincial Police used the Facebook networking site to thwart an illegal bush party planned by teenagers over the weekend.

More than 700 teens had said they would attend the bash, on private property in the Tillsonburg area, about 175 kilometres southwest of Toronto. Party details had been posted on a public page of the social networking site.

Now get off my lawn, dagnabbit!

Simply Amazing!

I cannot believe how cool this is! Photosynth combines flickr.com with an image processing algorithm to create an infinitely zoomable image.

The Photosynth Technology Preview is a taste of the newest - and, we hope, most exciting - way to view photos on a computer. Our software takes a large collection of photos of a place or an object, analyzes them for similarities, and then displays the photos in a reconstructed three-dimensional space, showing you how each one relates to the next.In our collections, you can access gigabytes of photos in seconds, view a scene from nearly any angle, find similar photos with a single click, and zoom in to make the smallest detail as big as your monitor.

People are drooling over Drobo

People are drooling over Drobo:

Data Robotics, Inc. | Drobo Product Specifications

Drobo Product Specifications

Four Bay Disk Interface
• 3.5″ SATA I or SATA II hard disk drives
• Full or half-height, no carriers required
• Choose the drive manufacturer, capacity (mixed capacities ok), and spindle speed or cache that fits your current storage needs

It looks like a cool device, and at $500 USD, it’s a bit pricey. I’d rather go with a more open solution that doesn’t need special software to run on the clients. Something like Openfilter:

File-based networking protocols supported by Openfiler include: NFS, SMB/CIFS, HTTP/WebDAV and FTP. Network directories supported by Openfiler include NIS, LDAP (with support for SMB/CIFS encrypted passwords), Active Directory (in native and mixed modes) and Hesiod. Authentication protocols include Kerberos 5.

Openfiler includes support for volume-based partitioning, iSCSI (target and initiator), scheduled snapshots, resource quota, and a single unified interface for share management which makes allocating shares for various network file-system protocols a breeze.

Updates from Amazon S3

Good news for people hosting with Amazon S3, wanting to do authenticated accesses:

Amazon Web Services Developer Connection : Improvements: Virtual Hosted Buckets and Object Size

The Amazon S3 team is excited to launch a significant enhancement to our virtual hosted buckets feature (also known as vanity domains). Customers who use vanity domains can now make signed HTTP requests against their vanity domains. Please refer to the updated Amazon S3 documentation for details. We’ve released updated code samples for this feature which are available in the Resource Center.

Swapping caps and ctrl keys in Windows

Another step in my mouse reduction:

Francis Tang: Geek Stuff | Win2k/XP Ctrl-Caps swap

XEmacs/Emacs users will understand this well: the Ctrl key is in the wrong position on modern PC 102 key keyboards. A better place for the Ctrl key is where it used to be, i.e. where the Caps key is now.
