Events

The LUG/IP Hardware Special Interest Group (SIG) meets on the first Tuesday of every month at 7 PM in the Hamilton (NJ) Public Library.

The SIG focuses on hardware issues relating to using Linux. The meetings are typically less structured than the general LUG/IP meetings, allowing for increased interaction between members.

If you need help getting Linux to run on your hardware, the SIG may just be for you!

Members bring computers and other hardware and help each other out with any difficulties they may be having getting Linux installed and functioning properly.

The SIG also often devotes time to general Linux, Open Source Software and other related discussions.

For more information about the SIG., contact the SIG coordinator, Chris Leyon chrisleyon@lugip.org.

LOPSA-NJ: January Meeting Find the Correct Fudge Factor: Implementing Accurate Network Time Protocol Servers!

Date: Thursday January 7 2010
Time: 7:00 PM - 7:20 PM - Social Time
7:20 PM - 7:25 PM - LOPSA-NJ Business and Announcements
7:25 PM - 7:30 PM - LOPSA-NJ Professional IT Community Conference (PICC) News
7:30 PM - 9:00 PM - Main Presentation

Join LOPSA-NJ as Jon Meek presents his latest experiments in highly accurate, low-cost, NTP servers. These experimental servers are based on GPS but use multiple methods to verify that they have the correct fudge factor.

Jon will present his poster, "Validating a Stratum 1 Network Time Protocol Server Find the Correct Fudge," recently seen at USENIX/LISA'09, with corrections, as well as disclosing his top-secret grandiose future plans, including:

+ using his new hot air re-work station to replace crystal oscillators
from motherboards in the servers

+ replacing the crystal with a fancy frequency synthesizer that has
an oven-controlled oscillator

+ using a GPS that outputs a 10 MHz clock signal as the base for
the clock

As Jon recently said on the LOPSA-NJ mailing list, "Stable system clock -> Better NTP stability."

It's clear that Jon has been a busy in his laboratory. We're all excited to see what he's cooked up!

Jon is a Senior Technical Lead at Pfizer with primary responsibilities in security, logging, Internet and third party connectivity, and network performance testing and monitoring. He joined American Cyanamid, a Pfizer predecessor company, 27 years ago is an experimental physicist to work on a project that required very accurate frequency measurements.
