J, Gleam, Lean Boost Dev Tools
Summary
These diverse developments in formal methods, language adoption, and system controls signal ongoing fragmentation and specialization across software infrastructure.
- OS Control Focus Low-level OS integration is explored via seccomp sandboxing and enhancing Win32 callbacks using closures [7, 8].
- Niche Languages Emerge Gleam was tested for Advent of Code 2025, while the J language implementation is documented [6, 5].
- Formal Verification Matures The Lean Theorem Prover’s Mathlib library continues to incorporate mathematical infrastructure and tactics 4.
- Specialized Hardware Serato released Slab, a MIDI controller built specifically for Serato Studio software 2.
- 8 - Total articles reviewed covering programming paradigms and controls.
- 4 - Key development areas identified: OS control, niche languages, verification, and hardware.
- 2025 - Publication year referenced for the Sektori game review and Gleam AoC test.
Key Moments
