I have done a few very small patches for open source programs, but would like to do more.

But how?%&!

I have a plan to do pull requests for a few select open source programs I use myself, but its hard. I am not a great programmer, I am a noob in Git, and I speak english as a second language.

Repeated from last years network fun, almost a tradition.

A small workshop teaching people how to produce DDoS simulation traffic - useful for testing their own infrastructures.

We will have a server connected on 10Gbps on a switch with multiple 1Gbps port for attackers. Attackers can be connected through 1Gbps ports using USB Ethernet - we have loaners.

Work together to produce enough to take down this server!

WHILE attack is ongoing there will be ample opportuni… Read more
