Time ago I written a post about how to have Discord installed using my own PPA mentioning that there were some limitations on the actual way of having Discord installed. For those who don’t know, Termius is probably the best AIO client for handling SSH connections nowadays: it provides an easy way to configure and connect to a remote (or local) server using SSH with a few clicks; it has an accounting system for synchronizing your keys between devices; and allows direct SFTP connections with the remote machine....

Have you ever looked for a Discord PPA? Would you like to have Discord up-to-date without depending on Snap Store on your Linux distribution? Let me introduce you a new PPA for having your Discord installation on your system with all features. Discord is a chatting and texting application whose motivation is to substitute both Skype and TeamSpeak as the desired chat application for gamers and general purpose. Currently, Discord is available for downloading for all platforms but, in Linux, it is only available for downloading as a raw .deb file or using the Snap Store, without any official PPA. As some users are against the Snap Store (due to its limitations, restrictions and policies), this repository aims to provide an easy solution for all users who want to have Discord installed and upgradeable. ...

Maybe you are a GoDaddy user, maybe you have heard about it. Nowadays, GoDaddy has become in one of the most important companies which helps webmasters and developers organize and host their websites easily and economically. But what you have maybe noticed is that there is no DDNS for updating the ‘A’ Record IP. If you do not know what an ‘A’ record is, basically it works like a routing way for finding the IP associated with a server. For example, suppose that you have bought the domain: example.com but your server is running behind a dynamic public IP so after some time it changes. If you want people to access your website through that domain, you will have to make that domain point to your actually public IP, having this value updated whenever it changes. As you may have notices, this is a “hard” work as you must be looking for any change on your public IP for updating the DNS ‘A’ records. Here it comes pyGoDaddyUpdater. ...

Docker se ha convertido en el nuevo estándar de despliegue de aplicaciones y en la nueva herramienta compañera del desarrollador. En este documento se va a estudiar cómo funciona Docker, cómo está compuesto, qué mecanismos usa para trabajar de forma eficiente y los conceptos relacionados al mismo: contenedores, imágenes, interfaces virtuales, volúmenes y gestores de almacenamiento. Por otra parte, el gran crecimiento conlleva unas responsabilidades de seguridad que no siempre se pueden abarcar. Se verá cómo Docker hace uso de mecanismos de seguridad del kernel de Linux para aislar los procesos con namespaces, crear interfaces de red virtuales con iptables y restringir el acceso a recursos con los control groups.
