Greek open source satellite…

"Young scientists constantly migrate abroad", "the best minds of our country are leaving him", "Masters and PhD holders only find jobs in coffee shops"; bitter headlines that we have all been reading in recent years in newspapers and on TV screens. And then: "The first Greek-made satellite is a fact". Obviously, the news doesn't invalidate it either (black) truth of the above, however, it also expresses a reality. An object as technologically advanced and as good in construction as a satellite was designed and implemented here in our country by Greek engineers, technicians and programmers, and in no time begins his journey to the International Space Station.
But let's start the story from the beginning. About five years ago, the Belgian non-profit Von Karman Institute;, which, among others, specializes in the aeronautical-aerospace sector, issued a call for interest to build a number of microsatellites; these would be part of an experiment to study the thermosphere, of the penultimate layer of the earth's atmosphere. Unique benefits to participants were the sensor that would be needed for the experiment's measurements and a "better price" for the satellite's journey into space..
Among the institutions that responded was the University of Patras, which decided to follow a difficult but much more interesting – and more economical – path: instead of ordering the various subsystems of the satellite ready-made from specialized companies in the space, he undertook to build it entirely with his own strength. So far so good, however in its beginnings 2015 and with time margins narrowing, το πρότζεκτ ήταν ακόμη βαλτωμένο λόγω των μεγάλων οικονομικών δυσχερειών καθώς και των προβλημάτων στη συνεργασία μεταξύ των διαφόρων διπλωματικών προγραμμάτων, τα οποία υποτίθεται πως θα συναποτελούσαν την τελική κατασκευή. Και τότε κατέφτασε τοιππικό.

End titles for the first version of Windows 10

Connecting to the source…
At 26 March of 2017 Microsoft will stop supporting the original version of Windows 10 [build 1507], so any systems based on it will stop receiving security updates and new features. The version 1511 of the operative, which is also known as “Threshold 2 Update”, as well as the Anniversary Update Edition, they will continue to be updated as normal, until they complete their life cycle later. Since the company makes the major Windows upgrades available for free 10, most home users will probably not be affected by this development. However, the same is not true for many businesses and large organizations, which have remained for various reasons in version 1507. In any case, all who have not already done so, they have until next March to update their systems to at least the version 1511 of Windows, otherwise they risk exposing them to malware attacks, or face compatibility problems with various devices and software. We remind you that just recently a Microsoft executive urged users to switch from Windows 7 on a newer operating system, stressing that since even these in a few years will cease to be supported, their use involves significant security risks.

Ένα σύστημα βιομετρικής αναγνώρισης σκοπεύει να εισαγάγει η κυβέρνηση της Αυστραλίας σε ορισμένα αεροδρόμιά της, με στόχο να αυτοματοποιηθεί περαιτέρω η διαδικασία ελέγχου. However, ειδικοί εκφράζουν τις ανησυχίες τους για ζητήματα που πιθανόν προκύψουν σχετικά με την προστασία της ιδιωτικής ζωής και την ασφάλεια των δεδομένων. The system – από το οποίο θα υποβάλλεται σε έλεγχο το 90% των επιβατών χωρίς την ανθρώπινη παρέμβαση- δεν πρόκειται να προκαλέσει περισσότερα προβλήματα στην προστασία της ιδιωτικής ζωής σε σχέση με τα σημερινά συστήματα ελέγχου των συνόρων, υποστηρίζουν άλλοι αναλυτές.Το υπουργείο Μετανάστευσης και Προστασίας των Συνόρων της Αυστραλίας, επιδιώκει να βρει μια εταιρεία η οποία θα αναπτύξει μια ‘αυτοματοποιημένη λύσηεπεξεργασίας των δεδομένων. Σκοπός είναι να υπάρχει ένας αυτοματοποιημένος έλεγχος των επιβατών, χρησιμοποιώντας τη βιομετρική ταυτοποίηση.

An international team of scientists led by a Greek expert found an unexpected connection between the immune system and the chewing of food.
In laboratory experiments, scientists from the University of Manchester in Britain, the National Institutes of Health (NIH) of the US and McMaster University in Canada discovered that a certain type of immune cell, the so-called Th17 cells, they are stimulated when we chew food well, protecting us from infections.
These cells play an important role in protecting against common bacterial and fungal infections of the mouth.Continue at source ...
