Vessel Fuel Consumption – or Restarting Running Sum

I got a question recently from Morten Braten whether my FIFO analytic techniques could be helpful for calculating the value of fuel consumption for cargo vessels. It turned out not to be quite the same, but similar. Analytic functions definitely could help.

I'll show how in two parts. First this blog post will calculate the fuel consumption in quantity, then part two will calculate the value by FIFO.

So let's setup a slightly simplified version (more...)

Bloggers Meetup at #OOW15

The last time I went to Oracle OpenWorld, I hadn't started blogging yet. Now I think it fair to call myself "blogger", even though I don't blog very regularly.

So I will try to attend the Bloggers Meetup:

I have heard a lot of good about it, so I am looking forward to see for myself ;-) Viewing who has RSVP'ed at either link, I know I spot some (more...)

Oracle OpenWorld 2015

In 2 days time I fly off to San Francisco for Oracle OpenWorld 2015. Last time I went to OpenWorld was 2008, so I'm looking forward to a re-visit and see how much bigger it has become :-)

Like everybody else I've been making a schedule for the week. Of course things will happen to change the schedule along the way, but some things I definitely have on the must-do list...

Scraping and querying Oracle Database Developer Choice Awards votes – Part 2

In Part 1 I demonstrated how to "scrape" data from the live webpages with the votes of the Oracle Database Developer Choice Awards. Unfortunately those webpages are not ideal for scraping, so I promised a workaround. Here I do a semi-manual scraping af data by using a browser to retrieve the actual HTML, save it to a file, and then let the code parse out the data from the file.



In the live version, the (more...)
