#MozWeekend Albania 2014

This weekend I had the pleasure to experience the first Mozilla Weekend event in Tirana, Albania. They were two days dedicate to Mozilla, it’s products, the community and of course the Open Web.

It was my first time in Tirana and the first time I was meeting the Albanian community in general. From the early beginnings, when Elio Qoshi first contacted me and invited me to the event I was able to see his passion. After I had the chance to meet the rest of the Albanian community I have to say that they all share the same passion. The passion of doing great things, the passion for knowledge and of course sharing their knowledge with other people as well. Let me try to describe the Albanian community with 3 words: passion, professionalism and hard working people.

So yes, the #MozWeekend was a blast! The event was well organized in an amazing venue with a great content. The attendant had the chance to learn about Mozilla’s vision about the open web, some of our amazing products such as Firefox, Firefox OS, developer tools and conquer the knowledge on how to create his first Open Web Application. And after creating his first Open Web Application he learned how Mozilla can help him on how to turn his idea to a product or a startup by signing up to WebFWD. He also leaned how is it to be part of an amazing community such as Mozilla’s, how to join and how can he help on keeping the web open and accessible for everyone.

I am really glad that I was part of the MozWeekend in Tirana because I saw the impact of the event in the attendees. I saw people’s hunger for writing Open Web Apps and contributing to our mission. It was really amazing!
Thank you #MozWeekend, thank you #MozAlb!
Hope to see you soon

Here is my Flickr album of the event

  2. Introduction to Firefox OS

Do you want to learn Python and Django?

A couple of weeks ago someone asked me on facebook for guides and tutorials on how to learn Python.

When I was looking for resources for my self some years ago I ended up buying the Learning Python from O’Really which I found really poor. I spend some hours reading the first 100 pages and learning only for variables in Python.

I wanted something more advanced, more fast learning, so I bought the Python Cookbook from O’Really as well. Yes (!) that was the book that I was looking for but still.

So then after a conversation we had with my good friend Diego he proposed me to read a tutorial regarding Django.

That was it! The Django Book was the best resource so far for learning Django and Python. The book is diving you in to Python and Django from the first 5′ minutes but with a great explanatory way. As a result you can set up your own Django instance in the first hour understanding every step on the way.

Other really helpful resources regarding Python for beginners as proposed from the Greek Python community can be found in the following links:

And for my Greek friends there an awesome guide for developing games in Python written by my friend Manolis.

Other resources proposed from readers, comments, social media.

So don’t be afraid and DIVE in to Python or Django!

If you are aware of more Python and Django resources for beginners don’t hesitate to leave a comment in order to update the blogpost.

Fedora Romania and OSOM

This February was an amazing month full with awesome events regarding Free and Open Source software.

In the mid of the month I was invited in Bucharest in order to have a session in OSOM conference. OSOM (awesome) is the annual meet up/conference of the Romanian FOSS communities and projects.

This year there were re-presenters and presentations from the following communities: Fedora Project, Mozilla, OpenSUSE, Java User Group, Ubuntu, Drupal and ROSEdu. All presentations were really interesting but I would like to choose Mozilla’s, OpenSUSE’s and ROSEdu’s presentations where they were simply amazing!

In this point I would like to give an extra credit to ROSEdu which is a group of people who promote and support open source in education. Way to go guys, keep up the great work!

During my presentation on Friday I had the chance to present the Fedora project and it’s community. I presented Fedora 18′s new cutting edge features and I put a special effort in our official spins and special interest groups. Romania was a challenge for me because except of my presentation I wanted to seek more active contributors along with the experienced ones like my best friend Nicu. I am really glad that I had the chance to spend to full days with him!

During the dinner after OSOM I was approached by Theodora which is a young developer who wants to be more involved in Fedora’s development process!

On Saturday, thanks to Marcela and Ioana, the two girls that made OSOM happen and with the help of ROSEdu, Fedora had it’s release party in the Facultatea de Automatica si Calculatoare. Along with Nicu, we had the chance to make a more detailed presentation of the Fedora Operating system and the Fedora wiki. We presented Gnome 3, some tips and tricks on that, Fedora Project’s wiki, steps on how to contribute in a variety of roles, how to translate and of course some hacking sessions. During the hacking sessions, we hacked our raspberry pi installing Fedora, we presented some cool GIMP tricks and finally we had our rpm packaging session.

The attendances were 15 and except some Fedora users the variety of them was from other FOSS communities such as Ubuntu and OpenSUSE but In the end of the day they all had a fresh Fedora installation!

Speaking of new Fedora users lets talk about new Fedora contributors too. Ioana Chiorean and Alex Lakatos expressed a lot of interest in contributing to Fedora project. Both of them are leaders in Mozilla Romanian community organizing A LOT of events and mentoring new contributors. Especially Ioana is willing to put a lot of effort in organizing and coordinating the Romanian community. I am really glad that I have the chance to mentor them in Fedora and watch them contribute in the project. Welcome guys and thank you for your effort! I am pretty sure that more updates are going to follow. ;)

Wrapping up my thoughts, OSOM was an excellent event where I had the chance to meet a lot of active and interesting FOSS contributors, see another perspective specially of open source in education, seek 3 new contributors and make a lot of friends!

Thank you Marcela, Ioana, Nicu, ROSEdu and of course Fedora for make it happen!

My photo album from OSOM and the Fedora release party can be found here.

FOSDEM 2013 – review

The first weekend of February of every year is always dedicated to FOSS Developers Meeting (FOSDEM) in Brussels.

FOSDEM is always a great opportunity to meet all my old Fedora and Mozilla friends from around the world. Unfortunately I didn’t get in time in Brussels in order to attend Fedora community’s dinner but I met them afterwords in the Delirium Cafe enjoying a large variety of beers. Right Christoph ;)

Saturday morning wake up is always tricky but along we Nikos we managed to get in time in order to prepare the Fedora booth along with Jiri where there was a surprising waiting for us as you can see in the picture above. Generally the most of my time I spend it in attending sessions but I did some contribution in Mozilla’s and Fedora’s booths too. This year’s Mozilla and Fedora booths where better than any other year with a lot of new and passionate people spreading the word of their favourite open source project and seeking more and more contributors.

It was another great year with a lot of enlightening presentations, a lot of awesome and brainstorming conversations with hackers from all over the world and of course a lot of hacking. The discussions you have outside dev rooms with amazing hackers, the brainstorming and all this energy can’t be compared with anything in the world. I want to give an extra credit to flash Fredy and Panos for having a live demo session in Mozilla’s booth, presenting Firefox OS devices the whole weekend! You were amazing guys, thank you! Finally I want to thank all the Reps who spend some time in booth talking with people, answering questions and solving problems.

As I blog posted before, more than 40 Greek hackers took over Brussels and FOSDEM where some of them run 8 sessions regarding open source software, open source hardware, their awesome projects or the project where they contribute in.

But this year was special for me too because it was my first time attending FOSDEM as a speaker. At Sunday noon I had a session in Mozilla’s dev room regarding debugging Firefox OS and open web apps as well as Gaia apps too. Thank you Clarista and Benoit for the excellent organization of the Mozilla presence. In general I think my presentation was a success despite the stress I had on stage. You can find my presentation online and you can always mail me for anything regarding debugging Firefox OS and Gaia.

World, watch out! Firefox OS is coming and it’s going to be astonishing!

FOSDEM 2013 is over and I cant wait a year for the next one! I am really glad for having a lot and great time with my old and new friends.

Invert colours in PDF files

Today I faced to following problem.

I wanted to print an ugly presentation which was stored in a PDF file. And I say ugly because the background was bright blue and the font of the text, yellow!

Printing this beauty in a printer will definitely empty all the ink in the first 10 pages. That’s why we have to invert the colours in order to consume less ink in printing.

After an hour of searching on the web I came out with empty hands! I have only managed to apply a Gray scale on the PDF using the convert command:

convert uglyPresentation.pdf -colorspace gray prettierPresentation.pdf

I am still having the same problem. The background instead of the ugly bright blue is ugly black/gray.

So I started reading the man page of the convert tool instead of searching on the web. Finally I came up with the -negate argument which replace each pixel with its complementary color.

convert prettierPresentation.pdf -negate beautifulPresentation.pdf

And we are set! Now I can print my presentation consuming less ink!

Conclusion: Read The F*** Manual

It is also well mentioned that you can invert or change the colorspace in other file types, like images.

Open Source and Research – talk, review

Two weeks ago – 27/11/2012 – , along with two great FOSS contributors shared a session in the Aristotle University of Thessaloniki in Greece regarding “Open Source and Research“.

The event was organized by the society of the post graduate department of physics and math of the Aristotle University.

Kostas KoudarasOpenSUSE contributor – explained the differences between free source and open source and elaborated on the movement/culture of Free Source software. In addition he explained the philosophy of contributing upstream and generally what do you achieve by contributing in FOSS projects.

Salih Elim – Open Source strategist at ErgoQ -  presented where free/open source applies in day life such as routers, cars, software etc. Later on the audience got amazed by a slide he shared with companies who use and support open source such as redhat, mozilla, google, toyota, ibm, nasa etc. In the end Salih, presented some open source projects which were a products of academic research and explained why should the community of an academic research project has to use, adopt and produce open source software/hardware.

In the last part of the session I – Fedora Project contributor, Mozilla -  presented the benefits of working/creating inside a community especially if that is an open source one. I tried to motivate people to join active FOSS communities or great their own, finding people with common interested. I shared a list with the most active Greek communities such as the Fedora’s Project, Mozilla’s,OpenSUSE’s and explained them why these communities rock, what do we achieve by contributing in these projects and invited them to join us!  I am pretty sure that people understood that through open source communities they can build the future of the open software/hardware as other foundation and foss companies (Red Hat, Mozilla) did in the past.

It was a successful event considering the fact that we had around 75 people, an 30′ session with discussing and answering to questions after the event and a lot of feedback.

I want to thank Thanos Pavloudis from the society of the post graduate department of physics and math (from the Aristotle University of Thessaloniki), who organized this event, made it happen and want to organize more events regarding Open Source.

Some more photos from the event can be found in my picasa web album.

Till the next time, keep hacking the world ;)
