Transmission Blocklist

The Transmission torrent client has an option to set a Blocklist, which helps protect you from getting caught and having the DMCA send a letter/email.

It's as simple as downloading and installing the latest client:

With heightening concern regarding the state of internet privacy (fuelled in part by the passing of the Investigatory Powers Act in the UK), I have set up a VPN server on the virtual server I have hosted with Mythic Beasts. This uses strongSwan and certificate-based IKEv2 authentication.

Assumptions:

• Debian Jessie server already set up and accessible via debian.example.com, a public IPv4 of 203.0.113.1 and a public IPv6 of 2001:db8::1
• Client username of me
• Clients are running the latest versions of macOS and iOS (Sierra and 10 respectively at the time of writing)
• No need to support any other operating systems (although the setup is easily translated)

For automated deployment of a similar setup, albeit Ubuntu-based and using ansible for deployment, I recommend you take a look at Algo VPN. I used that project as a basis for my configuration.

• Seus commits em repositórios do trabalho devem usar o e-mail fulano.silva@empresa.com.br
• Você possui chaves SSH diferentes para projetos pessoais e projetos do trabalho
• Tanto projetos pessoais quanto projetos do trabalho podem estar hospedados no GitHub, GitLab.com, etc.

# Automated AMI and Snapshot Deletion
#
# @author Robert Kozora <bobby@kozora.me>
#
# This script will search for all instances having a tag with "Backup" or "backup"
# on it. As soon as we have the instances list, we loop through each instance
# and reference the AMIs of that instance. We check that the latest daily backup
# succeeded then we store every image that's reached its DeleteOn tag's date for
# deletion. We then loop through the AMIs, deregister them and remove all the
# snapshots associated with that AMI.
