An **environment variable** is a variable in the system that can be used by programs.

A **virtual environment** is a directory with some files in it.

This page will teach you how to use **virtual environments** and how they work.

import java.util.Map;

/**
 * Parameter container class for data store configurations and runtime parameters.
 * This class provides a convenient wrapper around a Map to store and retrieve
 * data store specific parameters with type-safe access methods.
 *
 * <p>The class uses a ParamMap internally which provides case format conversion
 * between camelCase and snake_case parameter names for flexible parameter access.

```Python
if "johndoe" == "stanleyjobson" and "love123" == "swordfish":
    ...
```

Pero justo en el momento en que Python compara la primera `j` en `johndoe` con la primera `s` en `stanleyjobson`, devolverá `False`, porque ya sabe que esas dos strings no son iguales, pensando que "no hay necesidad de gastar más computación comparando el resto de las letras". Y tu aplicación dirá "Nombre de usuario o contraseña incorrectos".

TLS Configuration History
=========================

OkHttp tracks the dynamic TLS ecosystem to balance connectivity and security. This page is a log of
changes we've made over time to OkHttp's default TLS options.

_2019-03-14_

Remove 2 TLSv1.3 cipher suites that are neither available on OkHttp’s host platforms nor enabled in releases of Chrome and Firefox.
