Moongate is a modern Ultima Online server emulator written in .NET 10 with Lua scripting, featuring packet-layer client compatibility, spatial world partitioning, snapshot persistence, and NativeAOT compilation. The project prioritizes clean architecture with strict network/domain separation and event-driven design over the inheritance-heavy models of existing emulators like ModernUO.

Didit is a Y Combinator-backed identity verification platform that consolidates KYC, AML, biometrics, and fraud detection into a single API, emphasizing vertical integration, privacy-first design with minimal data collection, and transparent pricing accessible to early-stage companies.

This article explores how the /proc/self/mem pseudofile can write to memory marked as unwritable by bypassing MMU protections through kernel virtual memory subsystem manipulation, specifically via the FOLL_FORCE flag in get_user_pages() that skips write permission checks. The technique allows patching read-only memory including libc code pages, with implications for understanding kernel-hardware memory protection constraints.

A novelty web application that allows remote users to tune guitars using a physical Boss TU-3 tuner controlled by the creator. Not security-related.

A lighthearted exploration of the IANA Time Zone Database, highlighting the historical anecdotes and cultural commentary embedded in its source code comments, including stories about daylight savings time debates and quirky time zone adoption histories across North America.

Comprehensive mathematical introduction to knot theory, covering knot equivalence via Reidemeister moves, invariant polynomials (Kauffman bracket and Jones polynomial), Seifert surfaces, braids, and links in Euclidean 3-space. Provides theoretical foundations including prime knot factorization, the braid group presentation, and topological invariants for distinguishing non-equivalent knots.
