How was Game Of Thrones S07 E05? Tweet Analysis with Kafka, BigQuery and Tableau

I don't trust statistics and personally believe that at least 74% of them are wrong.... but I bet nearly 100% of people with any interest in fantasy (or just any) TV shows are watching the 7th series of Game of Thrones (GoT) by HBO.

hen Jeff Bezos, founder and CEO of Amazon, started out Amazon, he, along with Shel Kaphan, programmer and a founding employee, used sixty-dollar doors from Home Depot as desks.

It reflected its CEO's adamant belief in "frugality." A (more...)

Analyzing Wimbledon Twitter Feeds in Real Time with Kafka, Presto and Oracle DVD v3

Last week there was Wimbledon, if you are a fan of Federer, Nadal or Djokovic then it was one of the events not to be missed. I deliberately excluded Andy Murray from the list above since he kicked out my favourite player: Dustin Brown.

Possible solution for TLS 1.2 issues between Windows 10 and Oracle EPM Weblogic


We have recently seen some users of both Dodeca and Hyperion products where Windows 10 machines have issues connecting to the Weblogic servers shipped with Oracle EPM due to the absence of the TLS 1.2 protocol.  The underlying issue is that Windows 10 is an evolution of technology whereas Oracle EPM Weblogic, and more specifically the Java version tested and shipped with it, are stuck in the stone age.  Java 1.6 started its (more...)

Enabling A Modern Analytics Platform

Over recent years, bi-modal analytics has gained interest and, dare I say it, a level of notoriety, thanks to Garnter’s repositioning of its Magic Quadrant in 2016. I’m going to swerve the debate, but if you are not up to speed, then I recommend taking a look here first.

Regardless of your chosen stance on the subject, one thing is certain: the ability to provision analytic capabilities in more agile ways and with greater end (more...)

Unify – bringing together the best of both worlds

Since I started teaching OBIEE in 2011, I had the pleasure of meeting many fascinating people who work with Business Intelligence.

In talking to my students, I would generally notice three different situations:

  1. Folks were heavy users of OBIEE, and just ready to take their skills to the next level.

  2. They were happily transitioning to OBIEE from a legacy reporting tool, that didn’t have the power that they needed.

  3. There were not-so-good times, like when (more...)

Usability, Product Management, and LinkedIn – a rant

L
inkedIn began as a professional networking site, has evolved into a social media behemoth, and has yet managed to maintain and sharpen its focus on the professional space. That may, in part, explain why, in 2016, Microsoft chose to put down more than $26 billion Washingtons to buy LinkedIn.
While both LinkedIn's web site and mobile app have undergone substantial changes over the years, and is a far cry from the spartan look both (more...)
