Here’s a sneak peek at a video matrix — this is all the videos that include Pythian Group employees at the MySQL conference. I hope to have all the rest of the videos processed and uploaded within 24 hours, with a matrix similar to the one below (but of course with many more sessions).
This is not my notes about the MySQL conference that just occurred. These are my thoughts about MySQL conferences in general. During this year’s conference, I heard a lot of concern about whether or not O’Reilly would have a MySQL conference, and whether or not Oracle would decide to sponsor. I heard all of the following (in no particular order):
Recently I’ve been puzzled with the performance difference observed between 11GR1 and 11GR2. As part of the investigation I’ve decided to compare session stats from both 11GR1 and 11GR2 and found that there is a big difference for session cursor cache hits. But the number of session cursor cache hits I’ve been observing in 11GR2 just didn’t made any sense while being absolutely fine in 11GR1. An overflow was certainly a possibility, though in 2010, it’s not like someone should be counting every bit especially if they didn’t in 11GR1! Anyway it was worth a shot so I’ve decided to check it out…
It’s a busy time of year for Pythian. With many of our team tied up on client engagements, away at MySQL conference this week, and Collaborate 2010 next week, I’m pinch hitting as volunteer editor in helping to pull together this week’s edition of Log Buffer. Enjoy!
Good morning everyone and welcome to another edition of all the news fit to reprint. Last week iPad news was the number one topic on the hearts and minds of most places I visit, let’s see if the iPad can last another week or if a new champion will be crowned. Call or text your votes to … oh wait that’s someone else. :)
Once again into the breach. The release of Ubuntu 10.04 is at hand. I’ve been playing with “Lucid” for a couple of months now but since we’re in beta2 with the release candidate soon to follow, I thought I would really sit down and get my normal app stack working including TOra. All in all the instructions are mostly the same as last time around, with a couple of new improvements, caveats and quid pro quo.
Oracle invested heavily in open source even before the acquisition. Linux (Oracle Unbreakable Linux = Oracle Enterprise Linux = OEL). Clustering, data integrity, storage validation, asynchronous I/O, virtualiation technology that has been accepted back into the Linux kernel. They have enhanced Xen, in order to make a good Oracle VM server for x86. With Sun, they now have VirtualBox. In the 3 years of OEL, they have over 4,500 companies.
Good afternoon and welcome to another edition of Blogrotate. This week has been absolutely insane so it’ll be another short one I’m afraid. Luckily for me the majority of news outlets were binging on iPad related press which left only limited space for real news.
I’m excited to announce that Gwen Shapira has started with Pythian this week. :) Chen is no stranger here and many of my colleagues already know her and were in touch — she just naturally fits in.
Welcome to the first issue of Shuck & Awe: Hunting for Perl. Inspired by Blogrotate and Log Buffer, I’ve decided to try jump-starting a bi-weekly review of everything and anything that caught our attention in the Perl world. Okay, that’s enough introduction. Let’s cut down to the meat already, and see what I’ve collected for the last two weeks.
