Dalvik
Dalvik was Android's original virtual machine, a register-based VM that ran applications compiled to the compact DEX (Dalvik Executable) bytecode format. It was later superseded by ART.
Google Play
Google Play, launched as the Android Market in 2008 and rebranded in 2012, is Android's official app store and digital distribution channel. It introduced the 70/30 developer revenue split that became an industry norm.
Jekyll
The Ruby static site generator Tom Preston-Werner released in 2008; as the engine behind GitHub Pages it popularized blog-aware, file-based site generation.
Chef
Adam Jacob's configuration-management tool, first released in 2009, in which infrastructure is described as code using a Ruby-based DSL of recipes and cookbooks built from declarative resources.
Homebrew
The package manager that became the standard way to install command-line software on macOS, later extending to Linux.
Node.js
The server-side JavaScript runtime built on V8, with an event loop and non-blocking I/O, which made JavaScript a full-stack language and created the npm package ecosystem.
perf (perf_events)
perf is the Linux kernel's built-in profiling and tracing tool, built on the perf_events subsystem, which exposes hardware performance counters, kernel tracepoints, and dynamic probes through a single command-line interface.
MongoDB
The most popular document database, storing flexible JSON-like (BSON) documents instead of rigid tables, and a centerpiece of the NoSQL movement and the MEAN and MERN web stacks.
