Pebble is an embedded key-value storage engine written in Go, designed as a library that provides durable, write-optimized data persistence directly within applications. It organizes data using a log-structured merge-tree (LSM-tree) structure, where writes are first buffered in an in-memory skiplist memtable and persisted to a write-ahead log before being flushed to block-based SSTable files on disk. The engine supports atomic batch commits, configurable write synchronization, and automatic background compaction that merges and rewrites sorted runs to reclaim space and maintain read performanc

This project is a proposal for a new immutable date and time API in JavaScript. It serves as a precision time-tracking library and a multi-calendar date engine designed to replace the legacy Date object. The system is distinguished by its support for multiple calendar systems beyond the ISO standard and its use of IANA-based time zone resolution. It provides a framework for managing daylight saving transitions and UTC offsets while maintaining nanosecond precision for global timestamps. The API covers broad functional areas including complex date and time arithmetic, locale-aware formatting,

Drift is a type-safe SQL persistence library and relational mapper that provides a structured way to map database tables to classes and execute SQL queries with build-time validation. It functions as a type-safe query builder and a wrapper for SQLite and PostgreSQL, eliminating manual result set parsing by binding query outputs to native objects. The project distinguishes itself through a build-time code generation system that produces type-safe APIs and validates raw SQL statements against database versions before execution. It features reactive query streaming, which transforms SQL queries
