Speaking at Percona Live: common_schema, MySQL DevOps

In less than a month I'll be giving these two talks at Percona Live:

If you are still unfamiliar with common_schema, this will make for a good introduction. I'll give you multiple reasons why you would want to use it, and how it would come to immediate use at your company. I do mean immediate, as in previous common_schema presentations I happened to get feedback emails from attendees within the same or next day letting me know how common_schema solved an insistent problem of theirs or how it exposed an unknown status.

I'll review some useful views …

Open Source Enigma Project

The wild and crazy guys over at S&T Geotronics, James Sanderson and Marc Tessier, have decided to go full tilt with a Kickstarter version of their DIY Open Enigma Project.  For those who missed the fanfare last year, they were featured on Instructables showing how to build an Arduino-based encryption machine that works exactly like a WWII era Enigma.  You know, the thing that Alan friggin' Turing and his team at …

On the road again - FOSSAsia

On the road again - FOSSAsia

It has been a few busy months until now. I have moved from Italy to Thailand, and the move has been my first priority, keeping me from attending FOSDEM and interacting with social media. Now I start catching my breath, and looking around for new events to attend. But before I get into this, let’s make a few things clear:

  • I am still working for Continuent. Actually, it’s because of my company flexibility that I could move to a different country (a different continent, 6 time zones away) without much trouble. Thanks, Continuent! (BTW: Continuent is hiring! )
  • I am still involved with MySQL activities, events, and community matters. I just happen to be in a different time zone, where direct talk with people in Europe and …

Fun with MySQL and Hadoop at SCaLE 12X

It's my pleasure to be presenting at SCaLE 12X on the subject of real-time data loading from MySQL to Hadoop.  This is the first public talk on work at Continuent that enables Tungsten Replicator to move transactions from MySQL to HDFS (Hadoop Distributed File System).  I will explain how replication to Hadoop works, how to set it up, and offer a few words on constructing views of MySQL data using tools like Hive.

As usual with replication everything we are doing on Hadoop replication is open source.  Builds and documentation will be publicly available …

Steven Sinofsky on Disruption

There is a good article over at Re-Code by ex-Microsoft VP Steven Sinofsky called "The Four Stages of Disruption".  It describes the evolution of products and markets through disruption, drawing from Sinofsky's own insights and also building on the work of Everett Rogers ("The Diffusion of Innovations") and Clayton Christensen ("The …

Why I Love Open Source

Anders Karlsson wrote about Some myths on Open Source, the way I see it a few days ago.  Anders' article is mostly focused on exploding the idea that open source magically creates high quality code.  It is sad to say you do not have to look very far to see how true this is.

While I largely agree with Anders' points, there is far more that could be said on this subject, especially on the benefits of open source. I love working on open source software. Here are three reasons that are especially important to me.

1.) Open source is a great way to disseminate technology to users.  In the best cases, it is this easy to get open source products up and running:

$ sudo apt-get install software-i-want-to-use

A lot of software companies ( …

Kuali — Open Source Model Evolves

Kauli – Open Source Grown Up

Kuali is proof that the Open Source model works for more than nerds and geeks. Kuali is a movement where colleges and universities pool resources to develop the software they need to run their institutions. The parties involved provide money and bodies to work on the various projects. And if an school needs a feature in a hurry, they provide money or bodies to get the work done. This is a highly collaborative effort spans the globe.

Many of these same schools found themselves locked into very expensive software that had to be extensively tailored to meet their needs. Each upgrade was an expensive and time consuming process in an era of shrinking staffs and budgets. Regular upgrades were needed to support changes in regulations or latent needs. The cost of upgrades and customization was taking too much of scarce funds. This drove them into an open …

November 4, 2013 By Severalnines Percona Live London MySQL Conference - 11-12th November, 2013

And this is how we will be contributing to the event ...
