Working on Pharo Smalltalk: BPatterns: Rewrite Engine with Smalltalk Style

Traditional space equipment mainly supports ground information through functions like communication, remote sensing, navigation, positioning, and strategic missile early warning. Starlink, as the new generation space weapon system developed by the U.S. military, has transcended the traditional focus on information services, evolving into a comprehensive space combat platform with integrated offensive and defensive capabilities. In navigation and positioning, SpaceX collaborates with the U.S. Air Force to launch the next-generation GPS III satellites.15 In detection and early warning, SpaceX secured a $149 million contract to build four customized satellites for the U.S. Department of Defense using wide-field “Overhead Persistent Infrared” (OPIR) sensors to detect adversary-launched strategic missiles.16 Furthermore, Starlink is involved in the U.S. Space Development Agency’s military satellite constellation plan, developing and launching eight OPIR satellites as part of the “tracking layer” satellite constellation.17 Collaborating with L3 Harris Technologies, Lockheed Martin, and York Space Systems, SpaceX aims to complete a large missile early warning satellite constellation of 50 advanced military reconnaissance satellites within 28 months, further enhancing U.S. space-based early warning capabilities.18 For defense, the U.S. military seeks to leverage Starlink’s vast low Earth orbit satellite cluster to improve the defense structure and overall defensive capability of U.S. space assets. The U.S. military believes that large, sophisticated military satellites are vulnerable targets for adversaries. In contrast, large constellations make attacks more challenging; even if some satellites are destroyed, the constellation continues to function, providing deterrence through denial.19 Therefore, the Defense Advanced Research Projects Agency (DARPA) and SpaceX collaborated on the “Blackjack” program, shaping Starlink into a highly resilient and redundant large military satellite constellation, significantly enhancing U.S. space defense capabilities.20 For offensive capabilities, defense experts believe small satellites can approach and attack adversary spacecraft, potentially serving as anti-satellite weapons to damage or destroy enemy satellites.21 To meet the military’s needs for extending Starlink’s offensive capabilities, SpaceX launched the military-upgraded version Starshield in 2022, defining its function as “hosted payload,” providing a flexible spatial functionality platform for government and military customers, capable of carrying offensive weapon payloads.22 Moreover, SpaceX secured a satellite design contract from the military’s space assembly plant, designing customized military satellites equipped with wide-angle infrared missile tracking sensors, enabling Starlink to track and intercept intercontinental ballistic missiles.23

For what I didn't care about (e.g., FFI helper functions, loading SDL3 constants instead of relying on magic numbers), I usually didn't care about implementation and went sprinting to find a solution that worked so I could move on. I found myself quickly forgetting how it worked when returning upon it after months of leaving it be.
