# Summary of IRC Log from March 25, 2014

* A discussion about decentralized technologies included Bitcoin's reduction of OP_RETURN from 80 bytes to 40 bytes, with links to debates between developers about blockchain usage and proposals for distributed hash tables (DHT) as alternative storage solutions.

* Chris Dancy's quantified self work was mentioned, though participants noted his website lacked specific details about the sensors he uses for self-tracking.

* A research paper on C. elegans was shared, focusing on techniques for capturing neuron output, representing an advancement in understanding neural activity in this model organism.

* A DIY lightfield camera tutorial was shared, showing how to create a microlens array for building custom plenoptic cameras, alongside a discussion of commercial Lytro cameras.

* An open-source 2D synthetic biology game called "DSynBio_reloaded" was shared with a link to its GitHub repository and a related presentation video.

* A new record-and-replay debugging tool called "rr" was discussed, which allows developers to record program execution and replay it later to debug nondeterministic behavior.

* Several configuration management and automation tools were compared, including Ansible and Serf (serfdom.io), for managing server infrastructure.
