At the beginning of this month, I took the EX294 exam, which allowed me to obtain the Red Hat Certified Engineer (RHCE) certification. It was the first time I attempted the RHCE exam, but I prepared myself in the past for the EX300 exam, the exam that allowed you to obtain the RHCE certification in the RHEL7 time, but never got around to do the exam.
Compared to what I had to study for the EX300, I found the EX294 program way more sensible.Read More

A few years ago, I did pass this exam, but since then, the certification expired, so I had to re-take the exam. While the first time I did the exam in a testing center, this time I had to do it at home since all test centers are closed. The experience of doing the exam at home has been a very positive one since you can arrange the environment as it better fits you.Read More

Authentication factors One of the common way to create more secure authentication in systems is adding more “factors”, creating in this way a Multi-Factor Authentication (MFA). The idea behind MFA is that there are many different ways to authenticate a user, and those can be split in different “categories” based on the kind of challenge we require. Generally speaking, it’s common to divide the authentication methods in mainly three categories:Read More

Innotop is a tool that allows you to control the status of a MySQL/MariaDB database. It is widely used since it shows the data with an interface very similar to the top one.
Lately it’s development has slowed down, but small changes do come regularly.
The biggest change this time (compared to the 1.10.0-0.2 version) is the addition of a patch that allows innotop to work properly with MariaDB 10.1 and 10.Read More

One of my clients asked me to upgrade their MySQL 5.1 installation to MariaDB 10. This caused some problems mainly due to the fact that many MySQL clients are not MariaDB 10 ready. An example of a MySQL client not yet ready for MariaDB 10 is Innotop.
Innotop is a widely used client for MySQL/MariaDB that shows you an interface similar to the “top” Unix command. To solve this, I found a patch online and, after some testing, I’ve added it to the Fedora package.Read More
