Here's some news: MySQL, Sun's still-shiny new open source database acquisition, will be adding new features to its Enterprise (that is, paid) version that won't be added to the Community (free and open) version.

Here's the story at ComputerWorld: MySQL reserves features for paying customers; open-source community up in arms.

Oddly enough, though, the story seems to have originated on Jeremy Cole?s blog:
Just announced: MySQL to launch new features only in MySQL Enterprise. No press releases, and the news articles I've seen so far seem to be pointing to this blog entry (and MySQL honcho Marten Mickos' response/confirmation to the entry) as their primary source. …

Jeff Rothschild of Facebook’s “A Match Made in Heaven? The Social Graph and the Database”

Taking a look at the social graph and what it means for the database.

The social graph:

• At it’s heart it’s about people and their connections.
  
• Learning about people who are in your world.
  
• Can be a powerful tool for accelerating the use of an application.
  

“The social graph has transformed a seemingly simple application such as photos into something tremendously more powerful.” We’re interested about what people are saying about us, and about our friends. Social applications are compelling.

Facebook users blew through the estimate for 6 months of storage in 6 weeks. It is serving 250,000 photos per second at peak time, not including profiles. Facebook serves more photos than even the photo sites out there, and serves more event invitations …

From Jeff Rothschild, VP of technology, Facebook

1. The power of connectedness
2. Impact on the database
3. Our challenge 

• The power of connectedness
  • photo tagging
  • getting an email that someone tagged a photo in Facebook
  • inter tagging between friends and it continues as a network
  • outstanding growth because of the photo tagging
  • 26B photos in archive now
  • Most trafficked photos applications than anybody else
  • events, invites impact on social graph
  • Opening up the social graph to outside and create a platform and API, so other developers can make use of it (28K applications so far)

On Monday I had a chance to have a chat with Paul Vallee from Pythian. This was quite an enlightening talk, and I was very impressed by Paul openness and willing to share with me a lot of internal operations details. I wish there would be more people out where as open and helpful even when it comes to somewhat competing businesses. Though he is of course right - for small companies as we are there is much more business out where which is neither ours nor theirs and by being helpful to each other we can increase part of the pie to share.

Paul has significantly older (10 years) and larger (70 people) company so he has a lot to share. They have great internal systems and there is a lot we can learn from them in this area. We do fine with ours so far having just 7 active consultants but as we grow we need to get much better.

When I'm saying …

Identity 2.0: A world that’s simple, safe and secure.

Who is the Dick on My Site? by Dick Hardt (Sxip Identity Corporation)

Quotes:
“Really, data is about people. It’s really identity data.”

“Identity helps you predict behavior.”

“Identity is who you are.”

“Identity is also what you like.”

“Identity enables you to uniquely identify somebody.”

“There are things that other people say about you, too.”

“Modern identity is about photo IDs so you can prove your identity.”

“Identity is a complicated issue….Everyone has a different idea of what it is.”

Identity transactions are:

• party identification (who)
  
• authorization (permission)
  
• profile exchange (info about that person)
  
• NOT record matching
  

Identity transactions can be: …

Setting up replication is not hard and can be done by following simple directions. You can learn setting up two type of replication MySQL offers here: master-master replication and master-slave replication. Once you have replication set up, you can start playing with it without doing any more changes to the configuration. But let us face it, using replication in production environment and for sites which are either going live or are live, requires deeper knowledge of how replication can be used and what it can (or can not) do. We will start this “MySQL Replication Series” with briefly going over how MySQL replication works. Later in the series I will be posting some tips on …

I went by the MySQL Users Conference on Tuesday and it looked good, plenty of energy and attendance. Check PlanetMySQL for reports, the bloggers are doing a good reporting job; SlashDot is not, though - see below. A quick pass through highlights:

Yesterday’s keynote panel on “Scaling MySQL — Up or Out?”

Keith Murphy managed to take painstaking notes with all the facts and figures. As well, Venu Anuganti presents a chart with the results as well as notes on the more detailed answers. Ronald Bradford has a brief summary of the 20 seconds of wisdom from each panelist.

I love this anecdote from Jonathan Schwartz's blog. As is demonstrated again and again, enterprises have no idea just how awash in open-source software they are...until they ask.

The CIO responded categorically with "we don't run MySQL, we run [name withheld to protect the proprietary]." The CISO said, "We can't just let developers download software off the net, you know, we've got regulation and security to worry about." The CTO smiled. Everyone else appeared to be sitting on their hands. I was going to leave it at that. Thanks for the business.

Until a (diplomatically) assertive Sun sales rep piped up, "Um... no, I connected with a buddy of mine over at MySQL, and had him check - you've downloaded MySQL more than 1,300 times in the last twelve months."
