Here is the new office setup with a lot of changes since I moved to a new house.
Starting with the new desk that I got from Jarvis, it is much bigger than the old Ikea one, more stable, less noisy and able to stand up. Curtains are not in the best setup yet, I am working on this!

Last weekend I attended FOSDEM 2019 and I was amazed how big is this.
Since 2001, FOSDEM is a free and non-commercial event organized by volunteers for software developers to meet, share ideas and collaborate. Every year, thousands of developers of free and open source software from all over the world gather at the event in Brussels. It’s widely recognized as the best such conference in Europe.
Attending to the FOSDEM 2019 conference, we could have a deeply immersion in many subjects from more than 728 speakers, 776 events, and 62 different tracks.
The event itself starts only on Saturday, but at day before and after, you have the opportunity to attend to additional workshops, like Pre and Post-FOSDEM events, plus lots of other conferences awareness around the world. So it’s a great opportunity to catch up with the developers and sysadmins community and see what’s is going on at moment. The experience to be there in person is unique!
Also, all the speeches are recorded (automated!) and if you missed any speech that you wanted to watch, you can watch the videos anytime you like. I had a friend speaking on Saturday, and also anyone who wishes to give a speech is free to submit.
