This is my first post for 2018 (hooray!) and hopefully not the only one. I am writing this blogpost because a paper in which I was a leading author (together with some amazing co-authors) recently got published on IEEE Communications Surveys & Tutorials (IEEE COMST). Yes, it is a survey paper, it took me a really long time to write it and that’s why it needs a special blog post.
The paper is called “Towards Haptic Communications over the 5G Tactile Internet” and is a survey on the most important technologies and methodologies that will allow teleoperation with haptic feedback over 5G networks to become reality in the future.
One thing I found difficult when writing this paper was that because the topic is multidisciplinary, I had to find the correct balance to mix “all the cuisines in a single plate” (thanks Aravindh!). I had to satisfy the COMST audience, mostly interested in the 5G networking aspect, but also mention important aspects and challenges of bilateral control systems theory and haptic data processing.
You can either download a pre-print version of the paper here (link is under “Documents” section), or you can visit IEEE Xplore if you have access. Same thing basically.
Last but not least, many special thanks to all co-authors for their valuable contributions, help and support, but, also to the IEEE COMST anonymous reviewers for their suggestions that really helped in improving the manuscript.
Seriously, It was an embarrassing moment when I had to deal with the comments in my previous post as all I wanted to do is give people some piece of info on how to make their life easier using gnome-do. What I didn’t notice was that gnome-do is written in Mono (which I don’t dislike as it is hard for me to disapprove).
Carl van Tonder suggested gnome-launch-box and yes I had to give it a try and I did. So either go to Add/Remove Software (I use Fedora 13), or go to the terminal and type or copy/paste : su -c “yum install -y gnome-launch-box”
now you have installed gnome-launch-box. What is next, is to create a short-cut with your compositing window manager (I have compiz fusion). Go to the settings manager of compiz and then at General -> Commands. At the “Commands” tab go to “command line 0” (or whatever you want) type gnome-launch-box. Then go to the “Key bindings” tab and at Run command 0 (or whatever number you previously chose) enable it and then create the short-cut you wish. And now we are done!

Ώρα για την εξιλέωση! Αφού το gnome-do είναι λίγο ευαίσθητο από νομικής άποψης (λόγω του Mono) και δεν θέλουμε τέτοιους μπελάδες στο pc μας, προτείνω λοιπόν το gnome-launch-box. Μπορούμε πολύ εύκολα μέσω του Add/Remove Software, γράφωντας το όνομα (με τις παύλες) ή μέσω του τερματικού (su -c “yum install -y gnome-launch-box”) να εγκαταστήσουμε το πρόγραμμα.
Για να το λειτουργήσουμε εύκολα όπως και το gnome-do μπορούμε να δημιουργήσουμε μια συντόμευση πληκτρολογίου για να το καλούμε όποτε θέλουμε. Εγώ χρησιμοποιώ το compiz fusion. Στο settings manager του compiz πάμε στο General -> Commands. Έπειτα στην καρτέλα “Commands” πάμε στο “command line 0” (ή σε όποιο νουμεράκι επιθυμούμε) και γράφουμε την εντολή gnome-launch-box. Στην διπλανή καρτέλα “Key bindings” επιλέγουμε το “run command 0” (ή το νουμερο που επιλέξαμε πριν), ενεργοποιούμε και δημιουργούμε την συντόμευση που θέλουμε. Και είμαστε έτοιμοι!
YEAH!!! At last an open source event and it’s a big one, the Free Culture Forum . I can’t wait to go! It will concern mainly freedom of knowledge, digital rights etc. I also want to attend the participation of Richard Stallman through videoconference. I missed the Software Freedom Day here in Barcelona, I will not miss this one!
OK. Today’s post will also have some Greek as it concerns a big technology festival in Athens, Athens Digital Week, at which I participated last year with Fedora. Actually I think it was the first time I participated somewhere as a Fedora Ambassador. It also has an open source section thus last year we had Max Spevack‘s talk!
Ζηλεύω πάρα πολύ τα παιδιά που θα συμμετάσχουν καθώς είναι μια πολύ ωραία εμπειρία. Δεν μπορώ να ξεχάσω πόσο ωραία ήταν πέρσυ, με την συμμέτοχή του Fedora στο φεστιβάλ. Μιλάγαμε συνεχώς στον κόσμο, πχ η φωνή του Πιέρρου έκλεισε (μάλλον είμαι φτιαγμένος για να μιλάω πολύ) αλλά η κούραση που νιώθαμε στο τέλος ήταν γλυκιά, ήταν από κάτι που θέλαμε να κάνουμε και όσο το κάναμε νιώθαμε την ανταμοιβή.
Πλέον ως πιο εμπειρος Ambassador θα μπορούσα να βοηθήσω ακόμη πιο πολύ αλλα δυστυχώς είναι λίγο δύσκολο από την Barcelona. Ψάχνω απεγνοσμένα για κάποιο event εδώ, ώστε να βοηθήσω. Είναι δύσκολο να οργανώσω κάτι ο ίδιος διότι δεν γνωρίζω Καταλανικά αλλά και τα Ισπανικά μου δεν θα βοηθούσαν σε κάτι που απαιτεί συνεχή ομιλία.
At the previous paragraph I mention that I would be interested to help as much as I can (I have brought some Fedora and Fedora Electronic lab leaflets with me) in organizing an event here in Barcelona. I don’t speak catalan and my castellano are not the best, but I would love to participate (and also speak in English, not all people in Barcelona are locals).
And something out of topic, here are some pictures from the peaceful-interesting-beautiful Valencia :
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)

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.
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:
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.
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!
