Hi, my name is Paulo Pereira.

I’m a coordinator at SIBS, the central utility for payments, running the payment system end-to-end for more than 30 years, serving Banks, the Central Bank, government, etc. self

I’m a Linux and Open Source enthusiast in my spare time and I really enjoy reading. I’ve also been meditating since 2016 with headspace.

I lived through the 80s and 90s in Coruche, my hometown. In the year 2000 I moved to Lisbon to study in the Faculty of Sciences of the University of Lisbon, where I completed my Licentiate degree.

In 2005 I started working as a consultant in Novabase, where I stayed until 2017 when I joined SIBS.


You may reach me in several ways:

If you don’t know what XMPP/Jabber is, check my tips here.

It’s a good idea to protect your messages in the digital world. If you use an untrusted email service or messaging app, you can encrypt messages to me and verify it was me that sent a signed message at Keybase.

This is my public key.

I’m not a big fun of social media, but you can find me at Keybase, Goodreads, Mastodon, Twitter and LinkedIn. I’m not on Facebook or Instagram.

I’m currently running Arch Linux in all my personal computers. A NUC6i5SYH as my desktop, a NUC7i3BNH as my server and a Surface Go as my laptop.

It all started in the 90s playing around with Red Hat 5.2 (if my memory is correct). At that time it was just curiosity and Windows was still my main operating system. Even then I already tended more to the likes of Netscape, StarOffice and Firefox.

When I went to university my Red Hat musing started to be more serious and I started dual booting with Windows and trying several distributions. Between some others I used Fedora Core, Corel Linux, Mandrake, a try at Gentoo, SUSE, CrunchBang and later Ubuntu.

In 2009 I finally switched fully to Linux and at that time with Ubuntu. Following the LAS Arch Challenge in 2013, I switched to Arch Linux until today.

All around I used GNOME and for some time Openbox until Canonical started shipping [Unity](https://en.wikipedia.org/wiki/Unity_(user_interface). After that I started hopping between GNOME Shell, KDE Plasma, Xfce and lately i3-gaps.

Firefox as always been my browser of choice after Netscape. I used Chrome and Chromium for a period, but I’ve been back to Firefox for some time.

Other applications to mention are Thunderbird, Evolution and neomutt for mail, Thunar as my file manager, Gajim for instant messaging, Newsboat as a RSS reader, Zim for my notes and to-do needs, gpodder for podcast listening, vorta and borg for backups, YACReader for comics, HomeBank for personal accounting, pass as my password manager, and I could keep going.

Reading is one my favorite things to do since I was little. You can find me at goodreads and check my book lists, reading challenges and statistics.
