The Sacramento Java User Group meets
every month to discuss and discover new technologies that involve
Java and other electronic information systems. The group has been
meeting every month since the Java was released to the public back
in 1996. We are a volunteer group and the meetings are free to the
public. The hard work of its members and support of its sponsors
are the back bone of the group's success and longevity. We
recognize and appreciate those who have shared with the group
informative presentations and insightful discussion. It is those
members and guests who help make our meetings more enjoyable,
exciting and informative. Java is the language we speak and Java is the
language we love!
For those who are new or want to know details about the new
meeting location, SacJUG meetings are held at 6:00 p.m., on the
2nd Tuesday of the month at the ExitCertified office building.
ExitCertified is located at:
8950 Cal Center Drive
Suite 110, Bldg. 1
Sacramento, CA 95826
Members are encouraged to subscribe to
the SacJUG mailing lists. Outside of
our monthly meetings, our discussion list is the best place to
find out what's going on, to ask a question, or to meet new
Recruiters, here's how to get your job posting read at our monthly meeting,
or you can visit our announcement page
to post it electronically.

Getting Started with Java on the Raspberry Pi
The Raspberry Pi
The Raspberry Pi computer can support a full Java SE runtime for headless embedded applications.
The Raspberry Pi is a small, low-power board built around a 700mHz ARMv6 CPU with hardware floating point and graphics processor integrated in a single chip. The graphics processor and the CPU share 256MB of RAM. There are connections for USB, Ethernet, high-definition graphics, audio, an SD card, and general-purpose I/O. Figure 1 shows a Raspberry Pi model B with an SD card inserted for scale. The SD card plays a special role: The Raspberry Pi boots from it. This article largely consists of instructions for creating and modifying files on a bootable SD card.
