Students of Electronic Computer Systems engineering department of TEI of Piraeus, are organizing a technological festival called Openfest 2010. The two-day celebration is going to be held in the second weekend of March 13th & 14th to celebrate the pi day.

Operating systems laboratory is making an effort to create new forms of cooperation between the members of our educational community, in addition to the usual lectures and workshops. Thus, in this ambitious experiment, opens this Friday the 6th of November the event FreeFriday! FreeFriday is an alternative way for students who want to escape their last day of the week evening from reading, work, lessons, or a trivial hangout in the cafeteria with loud music and lack of creative communication.

This Friday, the 6th of November, we will gather at 20:00 at oslab. Visitors may attend 2 presentations about interesting technology topics, followed a film projection. The first presentation will be made by fellow student working on a large telecommunications company, about how ADSL line works. After the presentation, attenders will have clear knowledge on terms such as: DSLAM, POTS, etc. In the second half hour, there will be 2 associates presenting Rainup technology, a platform for running algorithms in cloud computing architecture, using the language Erlang! At the end of the evening a science fiction movie about accidental discovery of time travel is going to be projected!

Greek Ruby user group, organizes its second meetup in TEI of Piraeus, on Friday 16/Oct/2009 at 19:30, in Operating Systems Laboratory. The following presentations are going to take place:

• Deploying Rails applications στο appengine με JRuby [ PanosJee) ]
• Alternative ruby web frameworks (Ramaze/Sinatra/...) [ vtypal ]
• Μetaprogramming σε Ruby [Jon Romero ]
• How-to make a Rails plugin [ Jim Myhreberg ]
• Open Discussion & QA

Neo4j is a graph database. It is an embedded, disk-based, fully transactional Java persistence engine that stores data structured in graphs rather than in tables. A graph (mathematical lingo for a network) is a flexible data structure that allows a more agile and rapid style of development.

You can think of Neo4j as a high-performance graph engine with all the features of a mature and robust database. The programmer works with an object-oriented, flexible network structure rather than with strict and static tables — yet enjoys all the benefits of a fully transactional, enterprise-strength database.
