Here we are, after a time longer that what we would have liked to, in front of a new issue of EJS. In it, you will find four first quality scientific articles on different subjects, in particular data bases, object oriented programming and probabilistic analysis. Besides, you will find an article about monopolies in software industry, that has had an enormous repercussion in occasion of its publication in French and in English. Its author, Roberto di Cosmo, has allowed us to publish the Spanish version. The topic will probably generate polemics; if our readers’ reactions justify it, we will open the debate in our journal.

We have good news in the Events section. We have unified it with the corresponding (and new) section of SADIO’s home-page. From now on, that page will be maintained on-line by Pilar Suter. There we will try to reflect, as completely and dynamically as possible, conferences, meetings, exhibitions and other events, especially those taking place in the region. Anybody having information to communicate is invited to do it directly to Pilar.

Finally you will find, as in the first issue, the abstracts of some of the Ph.D. theses that were presented recently in the region. I invite everybody who knows about other theses (that surely exist), to send us the corresponding information.

In the letter that accompanied the first issue of EJS I wrote that making an electronic journal is not an easy task. Almost a year later, I can only confirm that opinion. Nevertheless, together with the SADIO people we still try to do it, and do it well. If the review process of the articles would not deserve so much care, if quality was not so important for us, we would have surely had our second issue earlier. But we are committed with quality, and we believe that that is the only possibility of success for a scientific journal. Surely the level of the articles presented here will be a stimulus for scientists and professionals willing to publish their contributions in EJS. I sincerely hope that we will not have to wait again one year before we meet again.

As in previous occasions, I repeat the invitation to all the community of Argentina and South America to contribute with ideas and collaboration towards the establishment of EJS as a medium of meeting and permanent update for all of us.
