Form the beginning of my blogging in the new web log , I always try to write a note, at least some paragraphs everyday. Today I was so busy with my papers and with network developing. First I had to correct my students’ papers. Some of the papers were very disappointing. I had another difficulty related to my web server. This server is running of PHP4 as a result some scripts don’t work properly with this version. I should say that PHP officials have supported PHP4 no longer. This would be my last post in this server because I was asked not to update my website for some while. If you see any inconvenience please inform me.
