Remote-Arbeit: Vergesst nicht das Gespräch am (virtuellen) Kaffeeautomaten!
Beim Wechsel vom Büro ins Remote Home Office gibt es eine vermaledeite Kleinigkeit, die den Informationsfluss stark hemmen kann – der Austausch am Kaffeeautomaten. Gespräche am Kaffeeautomaten sind eine wohltuende Abwechslung zur beruflichen Einspannung, bei der man gerne auch mal ein paar Minuten länger spricht. Menschen sind soziale Wesen und das gibt es auch im beruflichen Alltag immer wieder zu spüren.Continue reading
Using Date in Talend ETL jobs
One thing that always and again gets my attention is date handling in ETL jobs, especially in Talend and when using file input. It seems to me that sometimes there is no clarity about the concept of date fields and formatting. This post tries to clear things up.
Why meta data is one of the single most important topics in Business Intelligence
Have you ever been working with an internal or external customer who said he just needs this simple Excel into a report? When investigating the process, you find out that there are many undiscovered steps in this process?

Using the Eric 6 IDE for Python development – on Windows
It could have been so easy. I have been using Eclipse for a long time when I was still developing Java application.

Accessing the Open Data Portal Hamburg with Python
In a few tutorials which I tried was a very specific dataset being used – the NYC 311 calls dataset. 311 calls in NYC are some sort of support calls to easen the caller rate on the emergency number 911.
There are a lot of people calling this number over the time. The city of New York provides this anonymized caller data via its web page. I tried some stuff with it and liked the idea to work with „real“ data. Also, this dataset from 2010 to 2017 is about 9.5 GB in size – enough to play around with. In fact, I had to take a smaller one, representing only the year 2015 – still about 1.5 GB in size. This all is being provided in csv files.
So I wanted to find out if the city I currently live in, Hamburg, has some kind of data to play around with as well.

Why SQL Is a Horrible Language (When Analyzing It)
I like patterns. One of the first patterns I learned about was MVC, or Model-View-Controller. For those who don’t know, very roughly: it separates storage logic from presentation logic. When you use it, you have inevitably separate storage and business logic.
SQL does all at once. Oh, boy.
