We’re glad to announce the first HI Capacity talk about Bitcoin, the cryptocurrency. The talk will cover an overview of bitcoin, what it is, and a short history.

Here is the agenda:

  • Briefly cover what mining actually accomplishes. What are blocks, how does the network synchronize, proof-of-work.

  • The History and Future of Bitcoin mining hardware, the progression from CPU to GPU, through FPGA to ASIC.

  • Comparison between mining strategies, the differences between mining in a pool vs. solo mining.

  • Demo of what mining looks like and how miners are managed

  • Questions & Answers

The talk will be informal, with an emphasis on discussion about Bitcoin. The speaker is Ta'a Pyland. The talk will be held on June 18th at 7pm. The location is HI Capacity, which is located in the back of The Box Jelly (and to the left of Fishcake).

In April this year, Linode (a VPS provider) was hacked. The group that hacked them used a ColdFusion exploit to break into their servers. I want to show you how to do the exact same thing (on our own servers of course). First, we’ll go over the story behind the hack, then we’ll get into the hack and show a live demo of the hack. I’ll show you how you can replicate the hack and how it works. I’ll also show you how a simple node.js app can be exploited to do a similar hack as well. HI Capacity members will be free. Please email me (matthew@hicapacity.org) for the information and to be added to our RSVP list. This presentation is only open to 15 non-members at $15 per person. The money from the talk will go to HI Capacity to help us expand.
