From Latin cognātus — “born together”

cog·nate

/ˈkɒɡ·neɪt/ · adjective · descended from a common root

English night, German Nacht, Dutch nacht — different forms, recognizably related, one origin.

Cognate Press is the imprint behind six independent technical publications — one programming language each, one author each, each on its own domain. The imprint hosts nothing and aggregates nothing. It is a mark of authorship: where the asterisk appears, a single expert wrote every word, and they do the work they write about.

The publications

Gopheria
Go · gopheria.comThe Go runtime, the toolchain, and the standard library, read closely. — Anneke Visser ElephantPHP
PHP · elephantphp.comModern PHP from the engine up: opcache, FPM, and the machinery under the framework. — Muhammet Şafak PyDepth
Python · pydepth.comPython beneath the surface — CPython internals, the C API, and what typing actually promises. — Priya Raghavan JSLedger
JavaScript · jsledger.comAn honest account of JavaScript as specified, as shipped, and as broken. — Daniel Okafor JVMScope
Java · jvmscope.comThe JVM under observation: collectors, JIT compilation, and what profilers really measure. — Katrin Meyer SQLPress
SQL · sqlpress.comQuery planners, isolation levels, and the relational model taken seriously. — Elena Sokolova

Every publication opens on its own domain. The hub publishes nothing.

The expertise is the product. Each publication has exactly one byline — nothing ghostwritten, nothing syndicated, nothing generated.
