What are the programming and computer references in Steins;Gate?


I want to know the programming and computer references present in Steins;Gate.

For example, I noticed the SQL database is referenced.

SQL is mentioned, as the question suggests. They even used company and
trademarked names:

> MySQL, PostgreSQL, SQL Server, Oracle, DB2, SQLite, Access, ANSI

Of particular interest is the fact that Oracle, the company that owns Java, is
present. It's rare to find original trademarks in anime.

A book for "Goodle Endroid", a clear reference to Google Android, can also be
seen:

A book on SSH, the protocol used for remote administration, is shown, as well
as a book that mentions Unicode, JIS (essentially the Japanese equivalent of
ASCII), Java, Ruby 1.8/1.9, and Windows:
