# Key Points from #hplusroadmap IRC Discussions

• Participants discussed limitations of 3D modeling tools, noting that OpenSCAD lacks flexibility while POV-Ray offers good rendering but doesn't support geometry extraction or modern features like multithreading.

• A laser etcher project was migrated to a dedicated Git repository (http://diyhpl.us/cgit/laser_etcher/), with kanzure sharing an XY table design being developed in OpenSCAD.

• Tissue printing research was mentioned, specifically jmil's work combining 3D printed scaffolds with tissue printing for organ development applications.

• The channel discussed knowledge management challenges, with some preferring MediaWiki's familiar interface while others advocated for Git-based solutions like ikiwiki, WiGit, and Gitit (https://github.com/jgm/gitit).

• ENKI-][ expressed frustration with EEG software for Linux, noting that despite numerous "nia for Linux" projects existing, none functioned properly.

• Participants shared research on novel technologies, including a space debris removal concept (http://www.star-tech-inc.com/id121.html) and Tel Aviv University's development of protein-based transistors using organic materials as potential alternatives to silicon semiconductors.

• A technical discussion about DNS and SSL certificate setup occurred, with recommendations for free SSL certificates from StartCom.
