I’m flying with Firefox

Well, first of all, my find-something-bad-to-make-you-downgrade period for Fedora 11 is over and the results are as expected…using my computer on daily bases is a procedure that leveled up. But the beauty of it is that you know you are using free software. Software that is shared to you and belongs to you thanks to other people that believe in freedom. And then you say “hey! maybe I should contribute” because that’s your way to say thank you and learn stuff. That’s how I feel to be honest. So, just because I use Firefox every day for many hours, I decided to say thanks this time by contributing as a Test Pilot 🙂 . OK, I admit that I am also curious to see how this whole thing is going to work. I also can’t hide that I want to be a package maintainer for Fedora, but I have lots in my mind right now.

Furthermore, the last 3 days I try to focus on wireless sensor networks which of course means my familiarization with TinyOS and other technologies which are extremely cool. There is the need of great effort from my part though. Anyway, networks ,electronics and applications that can be used for HCI …no need to ask for more 🙂

I almost forgot CHECK THIS OUT: academicearth.org when I first saw it I tried not to behave like the men at the recent Heineken commercial (cheering like crazy). Thanks Christos!

Χωρίς λογική και ανθρωπιά ο νόμος είναι δώρο…άδωρον

Ναι το post αυτό αφορά το κάπνισμα και την απαγόρευσή του σε δημόσιους και ιδιωτικούς κλειστούς χώρους κτλ.

Δεν είμαι καπνιστής και δεν γνωρίζω την στέρηση του τσιγάρου. Δεν έχω μπει καν στον κόπο να δοκιμάσω. Δεν με ενδιαφέρει κι όλας αν κάποιος έχει αυτή τη στέρηση. Με ενδιαφέρει η υγεία μου και η υγεία των οικείων και άλλων προσώπων που συμπάσχουν μαζί μου.

Το πρόβλημα είναι απλό. Ένα άτομο έστω, ανάβει ένα τσιγάρο σε έναν κλειστό χώρο και αρχίζει και καπνίζει. Τριγύρω του για κάποιο χρονικό διάστημα έστω ότι υπάρχει ένας μη καπνιστής. Το αποτέλεσμα είναι ο μη καπνιστής να εισπνεύσει τον καπνό του καπνιστή. Ο καπνός αυτός μπορεί να ενοχλεί ή και να μην ενοχλεί. Σίγουρα βλάπτει την υγεία και την θέτει και σε κίνδυνο σε κάποιες περιπτώσεις μακρόχρονης έκθεσης στον καπνό.

Σε αυτό το σημείο να φέρω ένα άλλο παράδειγμα κάπως αντίστοιχο της περίπτωσης που ενοχλεί. Δύο φίλοι συζητάνε σε ένα τραπέζι και ένας άγνωστος ή γνωστός πάει με ένα τεράστιο στερεοφωνικό, βάζει την πιο αντιπαθητική μουσική με την ένταση τέρμα και αφήνει το στερεοφωνικό μπροστά στα μούτρα των 2 φίλων.

Για μένα η μόνη διαφορά με την περίπτωση του τσιγάρου είναι ότι το τσιγάρο μπορεί να βλάψει ανεπανόρθωτα την υγεία του μη καπνιστή (δηλαδή του παθητικού καπνιστή). Αν θες να πεθάνεις κύριε…πέθανε μόνος σου, εμένα δεν με ενδιαφέρει. Δεν σε ξέρω δεν με ξέρεις υποφέρω και υποφέρεις. Αν σε ξέρω δείχνει έλλειψη σεβασμού και μηδενική ντροπή. Μου προσθέτεις (έστω και ασυναίσθητα) ένα επιπλέον πρόβλημα στην ζωή μου. Το ότι το έχεις και εσύ και άλλα τόσα εκατομμύρια δεν αποδικνύει τίποτα.

Έχω βαρεθεί να βλέπω 14χρονα να καπνίζουν φανερά πλέον στους δρόμους. Καλύτερα στα φανερά, αλλά δίχνει πόσο δεν σέβονται την υγεία τους. Ζήστε πιο υγιεινά γιατί χανόμαστε! (και όχι χανόσαστε).

Fedora 11 released and me being busy.

OK. Now that I have the chance to take a break from studying, I can finally make a post. I’m in the middle of my exams period.

First of all, I’m writing from my clean-installed Fedora 11 x86_64 system :). You have to see it boot. Everything seems to work just fine. I just forgot to save my bookmarks :P. But! After the installation I didn’t forgot to yum groupinstallElectronic Lab‘ .

I am looking forward to start a project suggested from my professor at the TEI.  It will concern low power microcontrollers for wireless sensor networks. And guess what…it will be open source !!! (I just found out about uClinux and this) After my exams period I will try to find out how this can be combined with Fedora. Furthermore, maybe there is a chance I will do a little research (or something like that, I don’t know for sure yet) on HCI systems in collaboration with the University of Athens on February. I hope this will come true :). We’ll see.

I’m also getting ready for my studies at Barcelona, at the Facultad de Informática de Barcelona of the Universitat Politécnica de Catalunya  (UPC), I was accepted as an Erasmus student for the next semester. I’m in search of a place to stay. Single rooms with wifi and my own WC are hard to find though. I hope I’ll make it. I will also look forward to meet guys of the local Fedora community there. It’ll be fun.

To be honest I wanted this post to be for my presentation at NTUA which went well, not as many people as I expected. But hey! We never give up, and we always try to become even better. The presentation lasted for 1 hour and I tried to be as much prepared as possible. It’s not easy when you are a pre-graduate student of electronics to talk about VLSI systems etc. I am still waiting for photographic material to post.

Παρουσίαση του Fedora Electronic Lab στο ΕΜΠ

Το Fedora Electronic Lab αποτελεί μία από τις μεγάλες προσπάθειες ένταξης της free & open source ιδεολογίας στον χώρο του hardware.

To FEL είναι ένα Fedora Spin, μια συλλογή foss ΕDA εργαλείων που έχει ως στόχο την βελτιστοποίηση της ροής του σχεδιασμού των hardware projects. Ενώνει τον κόσμο του free & open source software με τον κόσμο του hardware.

Αφορά τους τομείς :

  • της μικροηλεκτρονικής (VLSI)
  • του σχεδιασμού και της εξομοίωσης αναλογικών/ψηφιακών/mixed κυκλωμάτων (spice, pcb και άλλα εργαλεία CAD)
  • τον προγραμματισμό ICs (PICs, FPGAs, προγραμματισμός με VHDL/Verilog)
  • τον σχεδιασμό ενσωματωμένων συστημάτων
  • της διαχείρισης projects.

Η Κοινότητα Ελεύθερου Λογισμικού του ΕΜΠ σε συνεργασία με τον Fedora-el διοργανώνει μια παρουσίαση του Fedora Electronic Lab. Στην παρουσίαση θα γίνει περιγραφή των στόχων και των χαρακτηριστικών του FEL καθώς και παρουσίαση ορισμένων προγραμμάτων του. Η παρουσίαση θα γίνει την Πέμπτη 4 Ιουνίου στις 3 το μεσημέρι στο MOΠ (cc.ece.ntua) Γενικές Έδρες Κτίριο Β Δεύτερος Όροφος από τις σκάλες αριστερά.


FossComm 2009 : recap :)

Friday 8/5 was  quite a busy day. After I finished my courses  etc. and once again I headed for home through the hell that has been renamed to “national road” at mid-day (all thanks to my fellow Greeks who crash their cars every now and then).  Anyhow, when I finally arrived home I picked up my Fedora and FEL (Fedora Electronic Lab)  leaflets, my laptop and everything else I needed to go to FossComm 2009 along with Pierros and friends.

Well, the trip was fine and we had a stop at Volos for a bit greek meze and a little bit of tsipouro. Afterwards we went to Larissa , got to the Hotel and relaxed in our rooms. I also met there my friend Alexandros. Anyways, Friday was not as interesting as Saturday.

Next morning we were at the TEI of Larissa to prepare our booth for Fedora for the whole event (along with Christos Bacharakis, Thalia Papoutsaki and Pierros) ! We unpacked everything, from fliers to OLPC, plus I had my laptop to show some programs on FEL. All guys there did a great job organizing the event. The atmosphere was relaxing and also exciting.

I can’t describe how the night went. Α word that could describe most of the people that attended the feast at the tsipouradiko (tavern with lots of tsipouro and greek meze dishes) would be “kurumpelo” which means drunk, but I believe we were more or less drunk but very joyful and in a great mood for company. (But seriously, I have no idea how the guy with the bicycle ended up safe at his house…)

FossComm attendies, presenters, organizers etc all together :)

Now, let’s talk about Sunday 🙂 .  Pierros Papadeas ‘s presentation on the Fedora project went really well! He really made clear of the goals, the people that support it, explained the four foundations etc…It was cool. Dimitris Glezos presented Transifex. For those who don’t already know, it’s an open source project, a localization web platform already used by the Fedora Project (Dimitris is a member of th Fedora Board!) and Red Hat, developed by Dimitris and the rest of  Indifex ‘s (yeap, his company) engineers team.

My presentation on FEL went quite good. It happened during our Fedora 11 Hackfest. I had to point out the goals of FEL, some interesting features that has and that will have (thanks Chitlesh!). I also presented some very interesting tools for design and simulation of circuits. I also mentioned the advantages of FEL, live every other Spin of Fedora has. It was my first presentation and the audience was not very into electronics (except to 2 out of 20-25 people). I had to try not to become boring, so I had to make changes instantly to what I previously prepared to say. Not the best feeling but at the end it was fun and I gained a great experience.

On Monday the Fedora 11 Hackfest continued but I was absent due to a lab at my school I had to attend.

I’m glad this post is over because there’s a lot more that I have to post. Busy week, busy month, busy year…

Czech Republic : Days 6-7

Hi again,

I’m back to Greece. No more vacations 😦 . Fortunately, I had really good time 🙂 .

Both Thursday and Friday were spent in Prague. I need to mention that on Thursday I had lunch at U Fleku. I had a goulash and 2 glasses of “U Fleků” beer which was just perfect!

Friday went a lot better than I had predicted due to the rainny weather. I had an espresso at the Prague Castle area and afterwards I visited the GIGABYTE Open Overclocking Championship and cheered for the greek team. The view from the 24th floor of the Corinthia Hotel was astonishing.

Czech Republic : Days 1-5

Hello everyone,

As you may have noticed from the title of the post I have set foot in Czech Republic since Saturday. I am having really good time, met many people (ok not as many as possible :P) and seen many beautiful places, monuments and buildings. I almost forgot to mention the beers :P. Can’t wait to make the of best of it as long as I’ll stay here. I’m staying at Hradec Králové at a friend’s house who studies Pharmacy here.

Saturday – Not much to do. Plain landed at 6 p.m. Took the bus to Mustek and then went to Hlavní Nádraží to get to Hradec Kralove by train (1,5 hour distance). Later on we went to a bar (had beer and a Long island iced tea and stayed till after midnight.

Sunday – Had a walk at Hradec Králové. Went at the center of the city, walked by one the two rivers running through the city (walked through bridges, visited parks, statues, squares etc)

Monday –  Took the train to go back to Prague. I really enjoyed the view of the countryside. Finally at Prague, what a beautiful city. The streets, the buildings, the people. Lots of tourists. I feel like the city is on the move but I not in front of my eyes. I guess that means I am really on vacation. I went to a Torture instruments museum. Freaky , huh?

But the best part of Monday was that I went to the roof of the Dancing House at Praha 2:

Dancing House trick

Tuesday – As busy as Monday. Went to Prague Castle and had a walk around the area. The view from up there is beautiful. Unfortunately, we had to leave to Hradec Kralove.

Wednesday – Just a break from my holidays to make new plans, charge batteries ( litteraly and metaphorically), relax and go back to Prague tomorrow. Oups!  I’ts Thursday allready. There’s a lot I did but didn’t mention.  Got to go though…2 days left.

FOSDEM (the summary)

The previous weekend was exciting and fun. I was at FOSDEM 2009 at Brussels (of course), not just to attend the various talks, but also to be present as a Fedora Ambassador at the Fedora booth. There are lot’s of names to mention, as the main benefit from such events is that you get to know people who always have something interesting to say.There is always more knowledge to gain.

More about my experience at the booth. As you may see in various photos of the booth, we had a lot of swag. Many of that stuff  (Fedora flyers, FEL flyers, buttons) were brought by the greek Fedora Ambassadors who attended the event, which is Pierros Papadeas (he really deserves most of the credit) and myself. No, I didn’t forget of Dimitris Glezos who was busy due to his Fedora and Indifex related plans!


Well, after a pleasant flight with Olympic Airlines, 6 greek open source guys were ready for action in Brussels. I couldn’t wait for the beer event which, eventually, was awesome. The Delirium Cafe was full of people. Most of the time (except when I had go and buy me a beer) I spent it on the outside talking with folks. Anyway, that’s what many other people did. The place was crowded 🙂


We tried to get to FOSDEM  as soon as possible with the addition of 3 greek guys we expected.  The booth was already set up. We placed the swag we brought. Our laptops were ready for people who wanted to try Fedora 10.

Most of the questions people had was about the OLPCs and the Sugar interface, but we did the best we could to promote Fedora to future contributors. Time went by and I couldn’t miss the chance to attend the RPM Packaging talk of Christoph Wickert, nor the Fedora Electronic Lab talk of Chitlesh Goorah. Both were great (you may see for your self at the links).

To be honest, at the FEL talk I got my self embarrassed. Something really funny happened. During his talk Chitlesh asked “Who doesn’t know what a LiveCD is?”. Instead of that I heard, “Who knows what a LiveCD is”. And guess what, I raised my hand and , of course, I was the only one. I explained immediately that I didn’t understand the question. The irony is that, as a Fedora Ambassador, I give hundreds of these cds and as a Linux user, there was no chance I wouldn’t have used one 😛 .

So, later on I was present at Max Spevack’s speech. I really liked the way he got his points clear with the “Red Hat employee” vs “Fedora contributor” approach, using (or not using) a Red fedora. Unfortunately, I couldn’t be there all the time. I had to return to the booth.

Oh yeah! I also got my Fedora Ambassadors shirt (thanks to Joerg Simon). Plus, I couldn’t resist not getting some of the Mozilla buttons and other swag, a FOSDEM and a GNOME t-shirt.

The night was interesting as well. Most of the Fedora guys , we went to another beer cafe. Chitlesh recommended a Kwak. Great beer, strange glass (the next morning I got my self one of those glasses). We had an interesting discussion about lots of things concerning Fedora.

An other day with lots to happen and lots to do. The combination of booth attendance + interesting talks was a bit tiring but I love to get tired this way. I attended the key-signing party which took place outside the building. It was freezing but we got the job done. There, I met a Spanish Debian guy. I tried to talk a little spanish, but after he started talking I couldn’t understand a thing. Lucky me he translated. I also went to the MediaWiki talk and  to the “Ruby and Java” talk, so I could get to know Ruby a little better.

When the night came, we went to the Delirium Cafe for once more (I could spend a year there).

Pierros, George and me spent Monday for exploring a little bit of Brussels.

Overall, a fantastic experience. Even more pictures here!
