EC2: Creating an Image. Here’s the easier way of creating your own AMI: start with a running instance in EC2, then customise it to fit your purposes and create a new bundle (and then AMI) using the ec2-bundle-vol command. # 7:50 pm
HOWTO Building a self-bundling Debian AMI. Not as terrifying as you would have thought. Also contains some neat hints as to how some of the more magical parts of EC2 work (like the way your SSH public key automatically ends up in /root/.ssh/authorized_keys). # 7:49 pm
Critical Mac OS X Java Vulnerabilities. There’s a five month old Java arbitrary code execution vulnerability which hasn’t yet been patched by Apple. Disable Java applets in your browser until it’s fixed, or random web pages could execute commands on your machine as your user account. # 7:07 pm
aws—simple access to Amazon EC2 and S3. The best command line client I’ve found for EC2 and S3. “aws put --progress my-bucket-name/large-file.tar.gz large-file.tar.gz” is particularly useful for uploading large files to S3. Written in Perl (with no dependencies), shelling out to curl to do the heavy lifting. # 11:38 am
