Geo Searches for Health Care Pricing Data

By | May 12, 2013

My presentation at MongoDB Days SF on Friday went very well, though I got to the last slide of my 40-minute talk in just 30 minutes. Hopefully, I didn’t speak too fast for a lot of people. Fortunately, I remembered at the end that I had also wanted to talk about how I saved space… Read More »

MySQL Conference 2010 Day 3

Monitoring MySQL with Cacti Cacti, like many other tools (Munin, Cricket, etc.), is a wrapper around RRDTool Baron feels that existing tools (zabbix, ZenOSS, OpenNMS, etc.) that try to do graphing and alerting do at least one of them poorly, though Reconnoiter looks promising. Cacti does graphing well RRDTool does interpolations, so you lose the… Read More »

Registered for OpenSQL Camp 2009

I’ll be in Portland on November 13, 14 and 15 for OpenSQL Camp, an unconference covering open source databases. In addition to learning more about MySQL and Drizzle internals, I’m looking forward to learning a bit about Postgres and some of the NoSQL database alternatives. They aren’t just your father’s high performance key-value stores, anymore.

Other programming languages like Python and Ruby might be gaining in popularity on Java, but Java is still pretty dominant. And just like last year, the queues for… Read More »
