K210. Alfre Mancera. Mensajes secretos
Descripción del Episodio
La criptografía es el arte de la escritura secreta. ¿Cómo mandar un mensaje que solo pueda leer su destinatario? ¿Cuál fue la primera herramienta de codificación que se utilizó? ¿Cómo descifrar el código de un enemigo? Estas fascinantes preguntas son el origen de la criptografía, un campo que Alfre estudia con pasión. Su libro Criptorias se divide en dos partes: antes de Turing y después de Turing, considerado el padre de la criptografía moderna. La escritura oculta es tan antigua como la propia civilización.
Me hace especial ilusión comercializar un producto que protegerá tus ahorros en estos tiempos inciertos. Pablo González Vidal, mi socio en El Proyecto K, ha configurado una magnífica cartera de inversión con una diversificación sectorial. La cartera, que invierte mediante ETFs de bajo coste, ofrece exposición de renta variable en 6 sectores: tecnología, salud, consumo, utilities, energía e inmobiliario. Todos ellos con un comportamiento distinto y con un peso previamente fijado, para así evitar una sobrerrepresentación. Se añade luego un porcentaje de renta fija y oro, en función de la respuestas en el perfil de riesgo, dándole la mayor robustez. Hemos decidido llamarla La Cartera K y funcionará como un roboadvisor que rebalanceará todas las posiciones automáticamente una vez al año. Puedes ya contratarla en inbestMe.
La Cartera K. Invierte en lo que no cambia.
La Cartera K es la evolución lógica de El Proyecto K. Abrimos el taller de inversión para que la gente aprendiera a construirse su propia estrategia diversificada. Ahora te damos la oportunidad de invertir directamente en una cartera que sigue los principios en los que creemos: indexación, activos descorrelacionados y bajos costes. Encontrarás todos los detalles aquí. Si quieres utilizar este nuevo vehículo de inversión para proteger tu capital, el proceso de alta no podría ser más simple: tienes que simplemente abrirte una cuenta en inbestMe y una vez dentro contratar tu propia Cartera K, ajustada a tu perfil de riesgo. Jordi Mercader es el CEO de inbestMe y quiero decir que no podríamos haber encontrado un socio mejor para lanzar este producto, en una plataforma de inversión que ofrece todas las garantías.

The Last 12 Weeks
By shows
In 1992, David Wood was convicted of murdering young women and girls and burying them in the desert outside El Paso, earning him the nickname the Desert Killer. More than 30 years later, his lawyers have one last chance to argue his innocence and stop his execution. “The Last 12 Weeks” follows a team of capital defense lawyers as they try to save their client’s life. The series, produced by Serial Productions and The New York Times in collaboration with The Marshall Project, focuses on the high stakes and at times bizarre work involved in trying to halt an execution. With an extraordinary level of access to a capital case in its final stretch, the longtime death penalty reporter Maurice Chammah takes listeners into the room with the lawyers as the clock ticks down. Maurice and Alvin Melathe, a producer, follow members of the defense team as they look for alternate suspects, try to find new evidence to poke holes in the case, and track down hard-to-find witnesses. In the end, will the lawyers’ efforts be enough to persuade a deeply skeptical court system — and stop an execution three decades in the making? “The Last 12 Weeks.” A five-part series … on a deadline.
