# Key Points from ##hplusroadmap IRC Conversation

• Magic Leap's augmented reality technology uses a high-speed digital zone plate to focus light at different depths, combined with a high-speed mask LCD running at 12x the frame rate of conventional imaging, though participants expressed skepticism about potential issues with chromatic aberration and power requirements.

• Advanced firearms technology like the TrackingPoint system incorporates fire control computers, barrel flex measurement via interferometers, and WiFi connectivity for sharing targeting data, representing significant integration of computing with traditional weapons.

• Security vulnerabilities in UEFI and Windows 8 Secure Boot were discussed, alongside a notable advancement in homomorphic encryption achieving 100x speedup using GPUs, enabling applications like Bayesian spam filters that can operate on encrypted messages.

• Participants shared technical approaches for DIY book digitization, including using OpenCV to capture video frames and Tesseract for OCR, with recommendations for proper lighting and camera setups similar to Google's book scanning approach.

• Language-theoretic security (LangSec) was highlighted as a promising approach to security by designing protocols to be context-free or regular, thereby avoiding complex parsers that can become attack vectors.

• The conversation revealed how corporate "acqui-hires" occur because traditional hiring processes reject up to 90% of startup-oriented talent, leading companies to acquire startups primarily for their teams rather than technology.

• Open-source CAD development was discussed with comparisons between FreeCAD (better for dimensioning and technical work) and Blender (superior for animations and rendering), along with mentions of emerging tools like VerbNURBS, python-brlcad, and cadquery.
