SSH Attendees will be provided with access to machines running Hadoop in a cloud environment. The necessary SSH credentials will be provided in…

  • SQL6048N A communication error occurred during START or STOP DATABASE MANAGER processing

    I’ve written about issues related to “SQL6048N A communication error occurred during START or STOP DATABASE MANAGER processing” before, but I thought I’d add a few short notes. Your machine needs to be able to ping itself. If it can’t ping itself, it can’t DB2 itself either. The output of hostname, db2set -all, and cat…

  • Chairing a Hadoop workshop at CASCON 2011

    I’ll be chairing the Crunching Big Data in the Cloud with Hadoop and BigInsights workshop at CASCON 2011 in Toronto on Wednesday, November 9th. @BSteinfe and @MariusButuc will be joining me as co-chairs.

  • Run Firefox 5+ and Firefox 3.6 side by side on Windows

    (Edit: Corrected instructions so that HTTP links in other apps will still open in Firefox.) There’s an intranet application that I need to use that does not work in Firefox 4, Firefox 5, Chrome, Opera, or Safari. It also runs painfully slowly in Microsoft Internet Explorer 8. Since it does support Firefox 3.6, I thought…

  • Example of #BigData: Social Media Counts

    http://www.personalizemedia.com/media/socmedcounter.swf Here’s an interesting example from the InfoSphere BigInsights/Hadoop class I’m attending right now. Note that Social, Mobile, Games, and Heritage are tabs that you can switch between.

  • Google Plus as a successor to LiveJournal

    Google+ is Google’s new social network. It takes aim at both Facebook and Twitter, but I think its unique intersection of features also positions it to succeed LiveJournal in a way that neither Facebook nor Blogger ever could. Let’s back up a bit. What is LiveJournal? LiveJournal, or Zhivoi Zhurnal as its Russian userbase calls it,…

  • IBM’s Hadoop distribution

    My work for the past couple years has been to develop DB2 images and templates for various cloud platforms and to engage the DB2 community online. This is still the case, but increasingly I’m spending my time working with IBM InfoSphere BigInsights. BigInsights is IBM’s distribution of Hadoop. What’s Hadoop? It’s a great way to…

  • Webinar on private clouds, including stuff I’ve been working on

    There’s a DB2 Chat with the Lab on Wednesday next week which will cover, among other things, the DB2 images I’ve developed for IBM Workload Deployer over this past while. I recommend checking it out, as the speakers know their stuff and this is a pretty cool product. Easily Deploy Database Workloads on Private Clouds…

  • Worst Google Translation ever

    I was writing a response to a forum post in Russian and thought to run it through Google Translate for verification. If nothing else, it would catch the sort of misspelling I tend to make. It surprised me by completely reversing the meaning of what I wrote: That’s the complete opposite meaning! This is the…
