On the value of calculating water balances

8 March 2016 By Antonis Christofides

If you are a reservoir engineer, you need money to do your job. Your financial managers don’t understand much about your work, and it’s difficult for them to prioritize the budgets; so they occasionally ask you to quantify the value of your work in financial terms. If this gives you headaches, this webinar is for you.

How to measure anything

29 February 2016 By Antonis Christofides

The Plastiras Lake in Greece is a typical example where everyone wants something different. The electricity company wants to use it to produce energy. The farmers want to use it to water their fields. The nearby city is supplied with water from it, and therefore wants the water to be of good quality. The tourist resorts around the lake would prefer it if the others didn’t take any water at all, because drawing water makes the lake less beautiful. So fifteen years ago we were given the task of studying these conflicting objectives and proposing a way to manage the lake better.

Enhydris: A free web application for meteorological measurement management

7 November 2015 By Antonis Christofides

Enhydris info panel(A presentation I made on 7 November 2015 at a Greek free software conference, the FOSSCOMM 2015, TEI of Athens)

Although my subject is Enhydris, we will only take a short look at it towards the end. We will first talk about development methodologies and about good and bad uses of technology.

Developing a great project

I am under the impression that unit testing is still considered something exotic by many developers. I think that this has to do with a certain kind of provincialism that we have. I’m not talking about Greece, but about many developers all over the planet who don’t work on great projects like Python and Django.

Τι να ψηφίσω; (Σεπτέμβριος 2015)

19 September 2015 By Antonis Christofides

Θα πρέπει πρώτα να διευκρινίσω την ιδεολογία μου. Δεν είμαι σίγουρος σε τι πιστεύω. Μου αρέσουν τα βιβλία του Χα Τζουν Τσανγκ (Ha Joon Chang), και πιστεύω πως θα έπρεπε να είναι υποχρεωτικό ανάγνωσμα για όλους. Το 23 things, που έχει μεταφραστεί και στα ελληνικά ως 23 αλήθειες, είναι θαυμάσιο. Έχω διαβάσει και το Bad Samaritans. Με βάση αυτά, νομίζω ότι θα μου άρεσε ένα σύστημα ελεύθερης αγοράς, [Read more…] about Τι να ψηφίσω; (Σεπτέμβριος 2015)

Τι είναι το ακαδημαϊκό άσυλο;

26 June 2015 By Antonis Christofides

Κύριε νομοθέτη,

αυτό είναι το άρθρο 3 του Ν. 4009/2011 όπως διαμορφώνεται μετά τις τροποποιήσεις (που επισημαίνονται με διαγραφές και μπολντ) που προτείνει το άρθρο 13 του υπό διαβούλευση νομοσχεδίου για την ανώτατη εκπαίδευση:

Άρθρο 3
Ακαδημαϊκή ελευθερίαΑκαδημαϊκές ελευθερίες και ακαδημαϊκό άσυλο

1. Στα Α.Ε.Ι. κατοχυρώνεται η ακαδημαϊκή ελευθερία στην έρευνα και τη διδασκαλία, καθώς και η ελεύθερη έκφραση και διακίνηση των ιδεών.

2. Το ακαδημαϊκό άσυλο αναγνωρίζεται για την κατοχύρωση των ακαδημαϊκών ελευθεριών, την ελεύθερη διακίνηση των ιδεών, την προστασία του δικαιώματος στη γνώση, τη μάθηση και την εργασία, έναντι οποιουδήποτε επιχειρεί να το καταλύσει.

2 3. Σε αξιόποινες πράξεις που τελούνται εντός των χώρων των Α.Ε.Ι. εφαρμόζεται η κοινή νομοθεσία.

Dangers from software patents in Europe

10 March 2015 By Antonis Christofides

(A presentation I made at an open source conference in Greece, 13 March 2010, at TEI of Piraeus.)

Getting involved with software patents seems boring, and, unfortunately, it is, at least for me. I’m a computer professional and I like writing code. I’m a Python/Django fan, and I’m involved in a couple of free software projects. One of them is a state project (and it’s free because I took the opportunity to move it towards the right direction when I saw that the right people were in the right positions). I don’t like politics and legal issues much. However, I do occasionally mess around with copyrights and patents; not because I like it, but because I like being free, and it is a price I pay to defend my freedom.
