# Summary of #hplusroadmap IRC Log (May 13, 2015)

• kanzure shared information about Indie.bio EU teams, highlighting innovative biotech startups including Aranex Biotech (developing non-allergenic peanuts) and Efflorous (engineering ornamental plants with unusual or extinct scents).

• A transcript of Greg Maxwell's presentation on Bitcoin selection cryptography was completed and repeatedly refined, covering advanced cryptographic techniques used in Bitcoin (available at http://diyhpl.us/wiki/transcripts/gmaxwell-bitcoin-selection-cryptography/).

• A critical security vulnerability (CVE-2015-3456) was discussed regarding QEMU's virtual Floppy Disk Controller, which allowed privileged guest users to potentially execute arbitrary code on host systems, with the vulnerability remaining exploitable even when administrators explicitly disabled the virtual floppy drive.

• kanzure added a document about heuristics and solution constraints to the DIY wiki (http://diyhpl.us/diyhpluswiki/projects/heuristics/), exploring approaches to problem-solving.

• A discussion occurred about deep sedimentary basins, noting that the Caspian basin has up to 26km of sediment fill, with implications for reduced radiation damage at such depths, potentially relevant for long-term preservation.

• There was a brief mention of fossil preservation practices, with kanzure noting a case where a discovered fossil was kept in storage for years before being properly examined.
