  • BASE: SQLite 3 Database

    by Robert Hansen and Ed Howland

    A database is used to collect, store, manage, organize and analyze information. There are many database systems. This session will introduce simple database concepts. Then it will cover the free SQLite database system that is likely the single most popular and widely deployed choice.


    MAIN: git: peering behind the curtain

    by Robert Citek

    After Robert's "A Gentle Introduction To git" last February, this will be a deeper dive, getting into some of the "behind the scenes" stuff that git does: where it stores files, how it stores metadata about the files, and how the files are organized.

    In a previous talk, we went over the basics of using git as a version control system, covering the working folder, the staging area, and the repository. In this talk, we will go behind the scenes to see how git works its magic. We will cover the abstractions git uses, in particular, a key-value store, hashes, and graphs. We will then dig into how git implements and uses those abstractions to create a version control system using files and the file system. We will walk through examples of using the back-end commands to build a commit history just like git does. Our hope is that by peering behind the curtain we can begin to demystify the magic of git.

    Monthly Meetings

    We open the room for the general meeting about 6:00 PM.

    Then we start at 6:30 PM with our BASE introductory level session (usually focused on personal computing); which may include either amazing graphical packages, blinking lights, command line wonders, demonstrations of useful applications, displays of newly discovered web sites, major resolution of long standing anomalies, quantum discoveries, smoke and mirrors, superb tutorials, or shifts in both time and space.

    Sometime after 7:00 PM we attempt a quick welcome, introductions, announcements, current events of interest, and a general CALL FOR HELP (Questions and Answers) segment.

    Sometime after 7:30 PM, we may take a short break before our MAIN topic (usually focused on enterprise computing),

    All of our meetings are free and open to the public. There is no individual membership fee.
