Lucidor: Un programa para la gestión y lectura de eBooks

reader ebooks
Lucidor en un lector de libros electrónicos, desarrollado bajo licencia libre y multiplataforma (GNU/Linux, Mac y Windows), que también nos permite gestionar nuestra biblioteca digital.

Una especie de alternativa ligera a Calibre, que soporta el formato EPUB y también los catálogos OPDS, que son una especificaciones técnicas que permiten leer, ordenar y distribuir publicaciones electrónicas, bajo estándares abiertos.
Lucidor nos ofrece una función básica de lectura, bajo una agradable interfaz y con ciertas comodidades: tamaño ajustable, modo columnas, búsqueda de texto, acceso a líneas o páginas previas, vista previa de links (opcional), fuente tipográfica, color de texto, color de fondo, biblioteca, indice de contenidos o la posibilidad de añadir anotaciones.
También nos ofrece acceso a diversos catálogos (Internet Archive, Smashwords, Feedbooks, Ebooks libres et gratuits, Bolselskap), desde donde podemos descargar libros de dominio público.
Cuando instalé el programa me llamó la atención que incluyera a XULRunner (entre otras cosas backend de Mozilla Firefox) como dependencia. Un paseo por los diferentes menús, enseguida nos muestra el motivo: Lucidor puede ser utilizado en funciones de navegador web.
lector ebooks
Como resultado de eso también podemos jugar con el asunto de la apariencia, añadiendo nuevos temas a los ya existentes (entre ellos uno de tipo oscuro y otro con texto agrandado) .
En la página del proyecto también encontramos algunas extensiones para MediaWiki (Luciwik, LuciwikEPUB) y un plugin (Lucimoo) para el módulo de libros, utilizado por la plataforma educativa Moodle. Además si usamos Firefox, disponemos de una extensión llamada Lucifox, que habilita la lectura de e-books (formato epub) desde el navegador.

Personalizar la apariencia de Linux Mint 18.1

Hay muchas maneras de personalizar tu Linux Mint 18.1, una buena cantidad de ellas son gratis, yo partícularmente no tengo mucho tiempo de ir instalando las cosas una a una, ir testeando y demás, por lo que me aprovecho de 3 scripts que nos van a permitir instalar varios temas, iconos y configuraciones para conky.
Para acceder a los scripts para descargar e instalar los mejores temas e iconos, debemos clonar el repositorio que contiene a ambos, además de los scripts para instalar por separado cada tema. Para ello debemos ejecutar el siguiente comando:
git clone https://github.com/erikdubois/themes-icons-pack.git

Script para instalar los mejores temas e íconos.

Para ejecutar el script all-in-once-installation_deb_themes.sh, que se encuentra en el repositorio themes-icons-pack.git que clonamos, debemos desde el directorio clonado, ejecutar el siguiente script de está manera:
./all-in-once-installation_deb_themes.sh
Esté script instalará automáticamente los siguiente temas para Linux Mint 18.1

For Communication

6. Pidgin

linux-apps-pidgin
Pidgin is the favorite instant messenger of many Linux users, and for a good reason. With support for all the popular chat protocols – Gtalk, IRC, Yahoo, ICQ, XMPP – and others (like Facebook) available via official and third-party plugins, who wouldn’t love Pidgin? It also works on Windows, and has many cool features, like custom emoticons, “Now Playing” status messages, different types of notifications, and buddy grouping and filtering.
Download

7. Telegram

linux-apps-telegram
Telegram is a relatively new player on the instant messaging scene, and it has the advantage over Pidgin (and many others) in that it supports almost all platforms (OS X and iOS, Android, Linux, Windows and Windows Phones). It’s focused on privacy and security, so it encrypts all messages and even lets them self-destruct if the users want that. All your chats are kept in sync across devices, and you can use Telegram to send files to groups of up to 200 friends.
