restfb
RestFB is a simple and flexible Facebook Graph API client written in Java.
It is open source software released under the terms of the MIT License.

Features

restfb has been designed with several objectives in mind. The most important of these are defined as follows.

Zero runtime dependencies

You don't need to include additional libraries in your project. There are no dependency conflicts. In addition, RestFB is highly portable and can be used in both Android projects and normal Java applications.

Maximal extensibility

Although we provide a standard implementation for our core components, each component can be replaced with a custom implementation. This allows RestFB to be easily integrated into any kind of project. Even Android projects are supported.

Minimal public API

TThe RestFB API is really minimal and you only need to use one method to get information from Facebook and one to publish new items to Facebook. We provide default implementations for all the core components, so you can drop the jar into your project and be ready to go.

Simple metadata-driven configuration

Our Facebook types are simple POJOs with special annotations. This configuration is designed for ease of use and can be used to define custom types very easily.

Download

RestFB can be downloaded from Github or used as a Maven dependency. There is also a sample project on Github.

The Dulce Venganza Apr 2026

| Philosophy | Stance | |------------|--------| | | No. Revenge treats people as means to an end. | | Utilitarianism | Only if it prevents greater harm and increases overall happiness. | | Virtue ethics | Rarely. Forgiveness is the virtuous path; revenge corrupts character. | | Retributive justice | Yes — punishment should fit the crime, and the victim deserves satisfaction. |

The phrase evokes the idea of revenge as a dessert: delayed, savored, and intensely pleasurable — but potentially unhealthy in excess. While “revenge is a dish best served cold” is an English proverb (likely derived from the 19th-century French phrase “La vengeance est un plat qui se mange froid” ), the Spanish phrase Dulce Venganza adds a crucial layer: the emotional quality of the act . It suggests not just patience, but enjoyment . The Dulce venganza

| Aspect | Bitter Revenge | Dulce Venganza | |--------|----------------|----------------| | Timing | Immediate, hot | Delayed, cold | | Emotion | Anger, rage | Satisfaction, cunning | | Method | Violent, messy | Clever, often non-violent | | Goal | Cause suffering | Restore balance + enjoy it | | Aftermath | Guilt, escalation | Catharsis, closure (often) | | Philosophy | Stance | |------------|--------| | | No

Still, in fiction — and in private fantasies — Dulce Venganza remains irresistible. It is the dessert of the soul: delicious, dangerous, and never quite as satisfying as we imagine. “La venganza nunca es buena, mata el alma y la envenena.” (“Revenge is never good, it kills the soul and poisons it.”) — Spanish proverb, often ignored in favor of the sweet version. | | Virtue ethics | Rarely

But the wisest stories and psychological studies suggest the same truth: the sweetest revenge is often living well . Not as a cliché, but as a strategy — building a life so full that the offender becomes irrelevant.

This write-up explores the concept not just as a literal act, but as a cultural, psychological, and narrative archetype. 1. Introduction: Defining the Term “Dulce Venganza” — literally “Sweet Revenge” — is a concept found in literature, film, psychology, and everyday morality. Unlike brutal, impulsive retaliation (often associated with “amarga venganza” or bitter revenge), Dulce Venganza implies a calculated, elegant, and deeply satisfying form of retribution. The “sweetness” refers to the emotional payoff for the avenger: the moment when justice (or perceived justice) is served, often with irony, poetic balance, or public humiliation of the wrongdoer.
