# Summary of ##hplusroadmap IRC Log (November 22, 2013)

The log contained minimal substantive discussion, but these points were noteworthy:

* kanzure shared information about ultrasonic bonding technology, linking to the Wikipedia article (https://en.wikipedia.org/wiki/Ultrasonic_bonding), which is relevant to manufacturing and materials science.

* A Wired article about prime numbers was shared and briefly discussed, with participants noting the sensationalist nature of the article but acknowledging the worthwhile references it contained.

* There was a brief technical discussion about domain-specific languages (DSLs) in Python, including an example of a filtering DSL that allows chained expressions like `eq("key", "value").neq("key", "other_value")`.

* Participants discussed issues with Library Genesis (LibGen), noting it had run out of disk space, received minimal donations (only 0.98 BTC in its lifetime), and needed approximately $950 for six months of server costs to maintain its 12TB digital library.

* Several academic papers were requested through the channel's "paperbot" service, which appears to retrieve papers from repositories like LibGen based on DOIs or URLs.
