I think, I’m ready for my winter vacation. During the last weeks my ordered hardware arrived:
On the left side you can discover one of my two WRTnodes. I ordered two of them to see how nicely they can work as mesh nodes. On the right side you find the Indiegogo founded project named VoCore, which I mainly use for Piratebox applications.
While I’m fiddling around with the new hardware, I hope you all have a merry Christmas and a happy new year.
See you soon!
I’m not a big python developer, but I’m able to read documentations. There are several expensive services on the worl wide web, that allows you to start AWS instances using a specific schedule. Some free services do not allow to bring up instances of expensive types like “c3.xlarge”.
For me, that is all too much, because I want to start a prepared AWS-instance once in a week. I created a solution, that uses an available Python library called boto and a common cron on a running linux machine (or a tiny RaspberryPi).
Note: This script does not create an Instance out of AMI-images, but you are able to achieve that as well.
You need to generate an AWS-service key -link is a documentation about that-, which you need to keep it as secret as your passwords.
from boto.ec2 import EC2Connection
from boto import ec2
conn = ec2.connect_to_region("region-abc",
aws_access_key_id="access-key",
aws_secret_access_key="secret" )
conn.start_instances( [ "i-4711" ] )region-abc to region you instances are located. access-key and secret should be replaced with the API credentials you generated above and the i-4711 you see in your overview on the EC2 list.1 3 * * 1 python ~/bin/start_aws_instance.py
I use this as a tiny, cheap solution to quickly fire and forget one instance. The script doesn’t fail, if the instance is already up and running. If you use this way to start the instance, you should add a shutdown option in your running AWS-instance. I use a build script fired up right after instance is finished with booting. After the complete script is processed, a norma shutdown -h now is initiated.
I don’t recommend to use this in a large scale or buisiness critical solution, but sometimes you need a “quick win”.
Starting today we are running a new webpage, which will I try to keep up to date with interesting things. I discarded the old one and I hope you enjoy our new blog.
best regards

Last month was Capitalware initiated MQ Technical Conference. There were alot of IBM technicians talking about new features in IBM MQ 8.0 (formerly known as IBM Websphere MQ) or how to use it efficiently.
You can find a complete list of the talks including the slide on the Capitalware MQ Technical Conference page.
Have fun with your studies!
This year I was able to sponsor with hardware and attend the PirateBoxCamp 2014 like last year, beside the important fact that the camp took place in Lille(FR) - LaCoroutine. LaCoroutine is a Co-Working space and offered us the location and some sort of catering.
Instead of having a bunch of talks we stripped down the agend to only a few overview and update talks. The team and the audience was happy to have several workgroups already on the first day hacking, testing and developing ideas around the PirateBox.
At the end of sunday, we had around 25 visitors sitting together and discuss about social implications of projects like PirateBox.
Special thanks to all organisators and LaCorouting to be our host.
