# Key Technical Discussions from #hplusroadmap

• DNA sequencing technologies were analyzed in detail, specifically Ion Torrent systems using "beads containing amplified copies of a single DNA strand" and Helicos Bio's approach to detecting fluorescence from single DNA molecules.

• Computer vision resources for Android were shared, including OpenCV implementation methods, Hough transforms for rectangle detection, and code samples for square detection algorithms.

• Participants discussed scientific instrumentation, including potentiostats for measuring arsenic levels in water and Vitamin C concentration in orange juice, demonstrating interest in DIY scientific measurement tools.

• A homemade Scanning Electron Microscope (SEM) project from Make Magazine issue 31 was referenced, complete with a YouTube demonstration video.

• Virtualization performance was compared, with recommendations to use KVM over VirtualBox for faster Android emulation, particularly on i7 processors.

• Advanced techniques for extracting files from binary installers were shared, using bash commands like rpm2cpio, awk, and tar to access content from self-extracting archives without execution.

• Microscopy techniques were discussed, specifically light-field and dark-field microscopes that illuminate subjects from different angles for enhanced imaging.

• A participant with experience in dental restoration materials offered to help design photocure polymers for 3D printing applications.
