Python 2.4.4 and boto-2.0b3 import hashlib error

Python 2.4.4 and boto-2.0b3 import hashlib error has a fix found here

Running an older Debian AMI with RAID0 XFS EBS volumes, I patch boto-2.0b3. Hopefully, have this instance migrated using a newer Ubuntu EBS AMI and use ec2-consistent-snapshot instead.

1. Copy a patch file to a temporary file:

# vi /tmp/c_14.patch
--- boto-2.0b3/boto/ec2/   Fri Nov 12 14:16:07 2010
+++ boto/ec2/      Fri Nov 12 15:19:21 2010

2. Now we can get the source of boto:

# cd /usr/lib/python2.4/
# mv boto-2.0b3-py2.4.eggboto-2.0b3-py2.4.egg boto-2.0b3-py2.4.egg.old

Nov-Dec 2010 Top Features of Amazon AWS

S3 Object Size Limit Now 5TB
Now object can be 5TB instead of 5Gb. Split the files and upload them using Multipart Upload API as posted here. I will always remember how to use AWS import and lxsplit for big data files.

AWS Mobile SDK
For mobile developers, check-out AWS Mobile SDK.

Amazon Route 53
This service is called Amazon Route 53 because of the port DNS is using. See it here. Hmm.. I suppose we can now run internal DNS without using LDAP and OpenDNS. 🙂

Free basic monitoring of EC2 instances nice! Hope more free to come.
