# Historia, Diseño y Futuro { #history-design-and-future }

Hace algún tiempo, <a href="https://github.com/fastapi/fastapi/issues/3#issuecomment-454956920" class="external-link" target="_blank">un usuario de **FastAPI** preguntó</a>:

> ¿Cuál es la historia de este proyecto? Parece haber surgido de la nada y ser increíble en pocas semanas [...]

Aquí hay un poquito de esa historia.

## Alternativas { #alternatives }

¡No! Esa no es la moraleja de la historia.

La concurrencia es diferente del paralelismo. Y es mejor en escenarios **específicos** que implican mucha espera. Debido a eso, generalmente es mucho mejor que el paralelismo para el desarrollo de aplicaciones web. Pero no para todo.

Así que, para equilibrar eso, imagina la siguiente historia corta:

> Tienes que limpiar una casa grande y sucia.

### Resumen { #summary }

Solía decir que no me gustaba mucho la historia... y mírame ahora dando lecciones de "historia tecnológica". 😅

### Summary { #summary }

I used to say I didn't like history that much... and look at me now giving "tech history" lessons. 😅

### Exceptions

Some legitimate exceptions exist where British English or other variants must be preserved:

* **Third-party APIs and libraries**: When integrating with external APIs that use different spelling conventions
* **Historical compatibility**: Existing public API methods that are part of Gradle's stable API cannot be renamed due to backward compatibility requirements (though new APIs should use American English)

 * See https://www.jetbrains.com/help/teamcity/teamcity-data-clean-up.html#Clean-up+Rules
 *
 * @param historyDays days number of days to store build history .
 * @param artifactsDays number of days to store artifacts. In the stored history, artifacts older than this number will be cleaned up.
 * @param artifactPatterns patterns for artifacts clean-up. If not specified, all artifacts will be removed.

the defaults for the Go toolchain used to build the program,
amended to match the Go version listed in `go.mod`,
and then overridden by explicit `//go:debug` lines in the program.

The [GODEBUG History](#history) gives the exact defaults for each Go toolchain version.
For example, Go 1.21 introduces the `panicnil` setting,
controlling whether `panic(nil)` is allowed;
it defaults to `panicnil=0`, making `panic(nil)` a run-time error.
