Welcome to my web site on computers. I'm working to add more content as time allows.
Content on the website will be relatedmainly to Linux and data / databases (I'm currently employed as a Database Administrator (DBA) for FlightStats.com), although you will find occasional articles related to Microsoft Windows.
The purpose of this web site is two-fold:
I am a Database Administrator for FlightStats.com. I work mostly with the PostgreSQL database engine although I'm looking at both MongoDB and Hadoop. I also do a limited amount of systems administration with Solaris and Linux - specifically Ubuntu.
A copy of the quick presentation I did on using AIDE for the local Portland Linux/Unix Group. Presentation was quick and dirty, and in PowerPoint format.
Do we need to sacrifice system uptime against system availability. And I use the term system availability to identify both uptime and unscheduled outages. So here system availability includes time from both unscheduled and scheduled outages. Why would I ask such a thing? Systems crash for all kinds of reasons: failure in the garbage collector to collect objects or collecting the wrong objects. So why do we need to do regular scheduled reboots of the system?
My slide presentation from PDX PG Day 2010 in Portland, Oregon.
The presentation was created in Open Office (the .ODP file - Postgresql (OSCON).odp), but I've also created a PPT version (Postgresql (OSCON).ppt) exported from Open Office.
