This post might seem anachronistic to you. In the world of social networking and web apps still with RSS feeds? There’s no denying that RSS feeds have gone out of style, but unlike their more modern counterparts, they are standard, free and open. What is an RSS feed Simplifying as much as possible, an RSS feed is an XML file that, through a standard, computer-understandable format, allows you to track updates to a website. Once you subscribe to a blog’s RSS feed you will be able to receive a notification whenever new content is available on the blog. This way you’ll never miss any posts, so this technology is useful for both those who create content and those who enjoy it. ...

I already explained to you in a previous post how passwords have become a very important aspect of our digital lives. I told you how to build an effective password and how to use Bitwarden to store them without losing our minds. We should have solved the password problem for good, right? Right! Sorry to disappoint you, but there’s still one more step to take: enable two-factor authentication. What is two-factor authentication When we log in to a website we are authenticating ourselves on that site, meaning the site is trying to figure out if we really are who we say we are. In almost all cases, recognition is done through the use of a username and password. As we have seen passwords are insecure and some of our behaviors1 make them even less secure. To try to solve this problem we thought to recognize users not only through the knowledge of a password, but also through an additional factor. ...

In a previous post we saw what a backup is and why it is essential to perform it regularly. We also mentioned the existence of some software that allows you to facilitate and automate backup operations. So now it’s time to discover one of these software and understand how it works and how to make the most of it. Borg Borg is a free and open-source command-line tool that allows you to create de-duplicated backups and makes use of compression and encryption. There are a lot of big words, so it’s best to analyze one point at a time calmly. ...

Passwords are a fundamental element of our digital life, but few people treat this topic with the attention it deserves. It’s not unusual to come across users who use the same password for all services or who have their year of birth as their phone pin. In this post, I’ll explain what a good password is, how to create it, and where to store it. What are the characteristics of a good password? The main characteristic of a password is uniqueness. You can’t have two passwords that are the same; this rule allows for no exceptions. Using the same password for two different services irretrievably compromises security. Unfortunately, data breaches are becoming more and more common and very often include passwords in plain text. If you use the same password for all accounts, all it takes is for one account to be compromised and like a domino effect all the others will fall. I already know what you’re thinking: “It’s impossible to use a different password for each service and remember them all.”; rest assured there is a solution, just continue with the reading of this post. ...

31 March has been chosen as the date of World Backup Day. The choice of this date isn’t random, but it’s a joke with the meaning we have given to the next day, April 1. This day serves as a reminder that April Fools’ Day can happen any day of the year, and we should be prepared. In this post we will see what a backup is and why it needs to be done. We will also try to understand how to make a good backup in order to secure our data. ...
