I’ll be traveling to the UK to speak at the XML Summer School this coming summer. I’m the guest speaker on the Web Services and Service Architectures track. The event takes place at Wadham College, which is part of Oxford University.

I’m not sure, but I think this means that I can tell my (future) grandchildren that I was once a guest lecturer at Oxford University.

• The Freemium Business Model.
• Ruby on Rails 1.1 Released – Lots of cool stuff (that I don’t understand yet), including a JavaScript Generator, something called RJS which apparently translates some subset of Ruby to JavaScript, and some RJS Templates. I will be attending the Rails Conference in June to learn more about all of this.
• Sammamish Slough Restoration – I walk 6-10 miles along this Slough almost every Saturday morning and the changes noted in this article are definitely noticeable.
• Analyzing the S3 License Agreement – A fun post from Scott, who also has a great podcast. I didn’t write the license, but I’ll take a tiny bit of credit for encouraging our legal department to make it friendly to developers. In one of those billion-to-one coincidences, I ran into Scott in the Indianapolis airport earlier this month — I was visiting Purdue and he was about to head off to Silicon Valley.

Every day, a script on Syndic8 generates a backup file. This file grows in proportion to the number of feeds in the system and is currently about 1.3 GB in length. At some point I will need to generate multiple files, but for now I can handle files of this size.

As an experiment, I uploaded a recent backup file into Amazon’s new S3 storage system using the Perl / Curl sample built by the S3 team. This sample is a simple (and very elegant) Perl script which computes the proper S3 authentication parameters and then invokes the command-line version of the Curl utililty to access S3. Since I had already created an S3 bucket, I used the following simple command to upload the file:

s3curl.pl --id=MYID --key=MYKEY --put=MYFILE.tar.bz -- http://s3.amazonaws.com/jeffbarr/backup/MYFILE.tar.bz

The entire file was uploaded in just 23 minutes, for a net speed of 1 megabyte per second. I verified that the file was present like this:

s3curl.pl --id=MYID --key=MYKEY -- http://s3.amazonaws.com/jeffbarr

Note that the arguments each start with a pair of dashes, and that a further pair of dashes is used before the final URL.

This returned an XML structure, so I copied the output of the command to my public_html directory and opened it in Firefox.

It would be very cool if S3 returned the MD5 checksum of the file. That way I could run md5sum locally, and then compare it to what S3 returned. I will talk to the development team about this in the very near future.
