As discusse in a previous post, I use nebula to create a VPN connection between the various machines I use. Usually what I really care about this setup is the ability of consuming services those machine expose on my nebula network.
When I travel, I prefer to proxy my data through my nebula network. This allows me to not have to care about the limitations imposed in those networks, as long as I’m able to open my tunnel.Read More

pdfcpu is a command-line tool to perform actions on PDF files. It allows to perform all the standard operations, such as merge, split, and rotate pages. It also allows less common operations such as changing the user and owner passwords, encrypting/decrypting, optimizing, etc.
The project started back in 2017, but I discovered it only last year. I like pdfcpu due to the high focus on allowing and making it easy to perform those kinds of operations in batch.Read More

A couple of weeks ago, I’ve announced the availability of AWS tools for Fedora. I’m very happy to announce that today they are available in the EPEL7 repository as well.
The Extra Packages for Enterprise Linux (EPEL) repository is an RPM repository managed by the Fedora community that creates, maintains, and manages a high quality set of additional packages for Enterprise Linux, including, but not limited to, Red Hat Enterprise Linux (RHEL), CentOS, Scientific Linux (SL), and Oracle Linux (OL).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

Have you ever had to develop a script in UNIX that has to send an email?
If you have, probably you have used the “mail” function since this program is the standard program to send e-mails in UNIX environments if you are using the CLI (Command Line Interface).
The manual for mail reports this as mail usage prototype:
mail -r [sender] -s [subject] receiver-1[,receiver-2,...,receiver-n] > [File with the body] I think all the parameters are pretty straightforward except the “File with the body” one.Read More

This is one of my favorite book about Linux. Probably is the most favorite one. In the last years I’ve been looking for a book that was like a printed man with some more explanation and a rigid order. This book does all this plus something more (that I’d rather not having).
I really liked the professional to professional user, since otherwise it would be much bigger and boring for pro users.Read More
