It is very common that UNIX / Linux systems that are accessed by SSH do not allow direct access with root. It must be authenticated as a normal user and then, if access is needed root, it is used suto get a shell root. On systems with OpenSSH, in the file /etc/sshd/sshd_configwe will find the parameter PermitRootLogin, which is “no” in many systems. Among […]
In this article we will perform a basic demo with React JS, and we will try to explain each step in detail, in order to understand most of the concepts that revolve around the development of an Application with React JS. For this basic demo we will use 3 main concepts, which are: React JS […]
In our previous article we learned What is Gulp.js? And how it works?, that is why we will now focus on the configuration of common tasks using the plugins that Gulp.js offers us. Here are some of Gulp.js’s most used plugins and their basic configurations: GULP-CONCAT Gulp.js plugin used to concatenate files. Concatenates files using the line break (newLine) from […]
In this article, we will learn how to use Gulp.js to improve and speed up our workflow by developing and trying to understand how it works. WHAT IS GULP.JS? Gulp.js is a build system that allows you to automate common development tasks such as minification of JavaScript code, browser reloading, image compression, code syntax validation […]
In the previous entry, Creating TCP / IP (port forwarding) tunnels with SSH: The 8 scenarios possible using OpenSSH, we saw all the possibilities we have at our disposal for port forwarding… but for static port forwarding. That is, we only saw cases where we wanted to access only a port of another system by chan- ging it […]
The typical function of the Secure Shell (SSH) network protocol is to access a remote system in terminal mode and execute commands there safely, because the data is encrypted. In addition, through this secure data connection, it is possible to create tunnels ( port forwarding ) between the connected ends so that the TCP / IP connections are channeled through the […]
Do you find the switch between Linux distributions frequently? When upgrading, do you favor clean installations more site updates?

Co-routines have been the biggest addition in Kotlin 1.1. They are absolutely great because of their power, and the community is still discovering how to make the most of them. Simply stated, co-routines are a way of writing asynchronous code sequentially. Instead of filling it all up with callbacks, you can write your lines of […]
In this first installment, we’ll explain how to use Jenkins pipelines with Stratio Big Data to get a complete lifecycle trace from the development team to the final production environment. During the “Lunch & Learn” on Stratus Continuous Delivery we looked at some of the problems and now we will try to explain them so […]
Even if you’ve never worked with her, you’ve probably heard of functional programming. And every day more, since there seems to be a hype with it. This paradigm of programming, which seemed to have been forgotten by the great mass of developers, has been reviving for a few years. It is true that other imperative […]
