MySQL Bugs On Dolphins, Panda's and Bugs

Like any good OpenSource project the MySQL Bugs website is open for anyone to search through. This ofcourse doesn't include the security bugs.

There is a second collection of bugs in the My Oracle Support and these bugs are only accesseble by customers with a support contract. Even when I have access to MOS I still prefer to use the community bugs site. For service requests etc. I would use MOS.

The openness of the bugs database is one of the topic the IOUG MySQL Council discusses with Oracle.

The bugs database has more to offer than just information about initial bugs:

MySQL version history (updated)

I've created a graph about the MySQL version history.

It's mysql-graph-history on github.


Please let me know if this is correct or if I'm forgetting some versions.

Find friends of friends using MySQL

In a previous article, I've already talked about an optimized way to connect locations in a geographic point of view by using MySQL. In this manner, locations of pubs, drugstores, barbers or even users can be obtained. Communities, or perhaps I should use the newer term Social Networks, make use of the buddy network of indiviual members in addition to the geographical mapping. This has many psychological advantages, because new members can be integrated in an established network very easily and I'm more willing to become involved when I already know some of the members.

Liveblogging at Confoo: Blending NoSQL and SQL

Persistence Smoothie: Blending NoSQL and SQL – see user feedback and comments at http://joind.in/talk/view/1332.

Michael Bleigh from Intridea, high-end Ruby and Ruby on Rails consultants, build apps from start to finish, making it scalable. He’s written a lot of stuff, available at http://github.com/intridea. @mbleigh on twitter

NoSQL is a new way to think about persistence. Most NoSQL systems are not ACID compliant (Atomicity, Consistency, Isolation, Durability).

Generally, most NoSQL systems have:

  • Denormalization
  • Eventual Consistency
  • Schema-Free
  • Horizontal Scale

NoSQL tries to scale (more) simply, it is starting to go mainstream – NY …

OpenSQLCamp Videos online!

OpenSQLCamp was a huge success! I took videos of most of the sessions (we only had 3 video cameras, and 4 rooms, and 2 sessions were not recorded). Unfortunately, I was busy doing administrative stuff for opensqlcamp for the opening keynote and first 15 minutes of the session organizing, and when I got to the planning board, it was already full….so I was not able to give a session.

OpenSQLCamp Lightning Talk Videos

OpenSQLCamp was a huge success! Not many folks have blogged about what they learned there….if you missed it, all is not lost. We did take videos of most of the sessions (we only had 3 video cameras, and 4 rooms, and 2 sessions were not recorded).

All the videos have been processed, and I am working on uploading them to YouTube and filling in details for the video descriptions. Not all the videos are up right now….right now all the lightning talks are up.

OQGRAPH at OpenSQL Camp 2009, Portland

Antony is travelling up to Portland for this great event that’s about to start Fri evening and going over the weekend. He’ll be showing other devs and people more about the OQGRAPH engine, and gathering useful feedback.

Open Query is, together with many others (I see Giuseppe, Facebook, Gear6, Google, Infobright, Jeremy Cole, PrimeBase Technologies, Percona, Monty Program, and lots more), sponsoring the event so that it’s accessible for everybody – reducing the key factor to getting there rather than having to worry about high conf fees.

Having acquired the world’s biggest jetlag flying to Charlottesville VA for last year’s OpenSQL Camp, I can confirm from personal experience that it’s a great event. While I can’t be there this time, I’m looking forward to hearing all about it!

OQGRAPH update: speed, maze example, 5.0 packages

Antony has done a bit of magic, considerably speeding up inserts. Since the base implementation does not have persistence, insert speed is particularly important. Copying the 2×89,051 edges for the Tree-of-Life example is now near-instant.

The delete bug has been fixed.

There’s a new Maze example in the OQGRAPH trunk on Launchpad, first introduced in my MySQL University session. I created/inserted a maze of 1 million rooms (that comes to about 3 million edges), and OQGRAPH found the shortest path (122330 steps for this particular maze) in abound one second. That’s pretty good, I think!

Last but not least, the …
