  3. Devoxx UK

    June 28, 2017

    I spoke at the London Devoxx event in June, on the topic of security and why it is more than just a case of selecting some security technology for your system – it needs to be a risk and cost driven approach.

  4. Fixing Lion’s Fur

    December 4, 2011

    I’ve upgraded my Macs to Lion (OS/X 10.7), primarily to allow me to migrate off MobileMe (that’s going away in the summer) and onto the new shiny iCloud replacement. While it all worked very smoothly, like many others I was horrified by the new look of the iCal and Address Book applications: What were they…

  5. WordPress Quick 404 Redirect Page

    February 11, 2011

    I’m not a competent PHP programmer but I’ve recently moved my website to a framework based on WordPress, with a custom theme designed by Alex Rozanski so I’ve had to learn the basics. Part of this migration was moving from my old custom PHP/HTML/CSS website to a new WordPress based structure and this meant working…

  6. Oracle JDBC, TIMESTAMP and WebRowSetImpl

    December 29, 2010

    A colleague at work had an interesting problem recently when retrieving a result set from an Oracle 10.x database via JDBC and translating it into XML using the com.sun.rowset.WebRowSetImpl class. The basic code was something like this: ResultSet rset = stmt.executeQuery(“select * from ..”); WebRowSetImpl wrs = new WebRowSetImpl() ; wrs.populate(rset) ; wrs.writeXml(System.out) ; All…

    June 20, 2010

    I’m in the process of learning Scala and recently discovered Phil Gold’s set of 99 Scala Problems.  I’ve been working through the easier ones and found them very useful and was planning to continue on a long flight I have tomorrow.  However, I found that the site wasn’t available as an offline archive for use…

  8. OS/X 10.6 Screen Sharing Login Problems

    April 30, 2010

    Nothing to do with software architecture or software development, but …. I use Macs at home and I’m one of these people who has had a pretty good experience with Apple and these days I normally accept all the software updates without looking too carefully. However, a recent OS/X 10.6 update (to 10.6.3 I think)…

  9. Getting the Hard Drive out of a 2006 iMac

    December 28, 2009

    My early 2006 iMac gave up the ghost a few days before Christmas and refused to respond at all to being switched on, so it was clear that something pretty terminal must be wrong with it and I replaced it with a new aluminium iMac.  (As an aside, this went much more smoothly than expected…

  10. Resurrecting old PowerPoint files

    December 28, 2009

    I was recently browsing through some archived files from a job long ago and discovered that I couldn’t open the PowerPoint files.  This surprised me because I thought that MS Office was able to open files from any previous version, but it appears not. Digging further, I found that the files in question were in…
