                      Kafka and Confluent

                      For starters:

                      At its core Kafka is very simple:

                      So it seems fair to say:

                      My favorite educational video

                      My favorite educational video growing up, by far, was a 1960 film embedded below. I love it because it pranks its viewers, starting right in the opening scene. (Start at the 0:50 mark to see what I mean.)

                      If you’re ever in the position of helping a kid or young adult understand physics, this video could be a great help. Frankly, it could help in political discussions as well …

                      MongoDB 3.0

                      Old joke:

                      A lot has happened in MongoDB technology over the past year. For starters:

                      *Newly-released MongoDB 3.0 is what was previously going to be MongoDB 2.8. My clients at MongoDB finally decided to give a “bigger” release a new first-digit version number.

                      To forestall confusion, let me quickly add: Read more

                      Cautionary tales

                      Before the advent of cheap computing power, statistics was a rather dismal subject. David Lax scared me off from studying much of it by saying that 90% of statistics was done on sets of measure 0.

                      The following cautionary tale also dates to that era. Other light verse below.? Read more

                      Three old jokes

                      Modern analytics described in three old jokes.

                      The drunk under the lamppost

                      A man is on his hands and knees, looking for something under a lamppost and obviously not finding it. The neighborhood policeman asks what he is doing.

                      “I’m looking for my keys.”

                      “Did you lose them around here?”
                      “Not exactly; I think they fell out of my pocket down the street a bit.”

                      “Then why aren’t you looking for them down the street?”
                      “The light is better over here.”

                      But seriously

                      Some people use statistics the way a drunk uses a lamppost — more for support than for illumination.

                      Seek and …

                      A family that’s looking to start organic gardening has a large pile of manure dumped into their backyard. Their daughter grabs a shovel and digs in excitedly, shouting:

                      “Look at all this … stuff! There must be a pony in here somewhere!!”

                      Comments on Oracle’s third quarter 2012 earnings call

                      Various reporters have asked me about Oracle’s third quarter 2012 earnings conference call. Specific Q&A includes:

                      What did Oracle do to have its earnings beat Wall Street’s estimates?

                      Have a bad second quarter and then set Wall Street’s expectations too low for Q3. This isn’t about strong results; it’s about modest expectations.

                      Can Oracle be a leader in both hardware and software?

                      Beyond that, please see below.

                      What about Oracle in the cloud?

                      MySQL is an important cloud supplier. But Oracle overall hasn’t demonstrated much understanding of what cloud technology and business are all about. An expensive SaaS acquisition here or there could indeed help somewhat, but it seems as if Oracle still has a very long way to go.

                      Other comments on the call, whose transcript is available, include: Read more

                      Metaphors amok

                      It all started when I disputed James Kobielus’ blogged claim that Hadoop is the nucleus of the next-generation cloud EDW. Jim posted again to reiterate the claim, only this time he wrote that all EDW vendors [will soon] bring Hadoop into their heart of their architectures. (All emphasis mine.)

                      That did it. I tweeted, in succession:

                      *Woody Allen said in Sleeper that the brain was his second-favorite organ.

                      Of course, that body of work was quickly challenged. Responses included:? Read more

                      The Wonderful One-Hoss Shay

                      I often write of Bottleneck Whack-A-Mole, an engineering approach that ensues when parts of a system are out of balance. Well, the flip side of that is the One-Hoss Shay, as in Oliver Wendell Holmes’ marvelous poem. (Here’s a version with Howard Pyle illustrations.)? Read more
