Spreadsheets: How to excel with Db2 data

Generated chart in Excel file
Recently, I had to produce a spreadsheet from database data. One naive way is to export the data to a CSV file, then import the data from that file into the spreadsheet. Another option was to quickly script a small Python program that fetches the data and directly generates a Microsoft Excel file. As a bonus, I added even a line chart (as shown).

Tutorial on cloud end-to-end security - an overview

Cloud solution architecture

Recently, my team updated our tutorial on applying end-to-end security to a cloud application. The tutorial features a typical app with an attached NoSQL database and object storage. Moreover, it leverages other services for increased security and to provide observability. Even better, all components can be automatically deployed, including a Tekton-based delivery pipeline. In this blog post, I am going to provide an overview and discuss some implementation details.

DeDUG: German Db2 User Group meeting February 2nd

The year 2024 is still young and a great event is coming up in about three weeks. DeDUG, the German Db2 User Group, is having their first meeting on February 2nd and is going to be at Atruvia in Karlsruhe. Best of all, I plan to attend and even give a talk. Currently, the agenda lists me with "Unicode und Db2", but I have renamed it to "How to treat 💔💔💔 (broken hearts) with Db2". It hopefully is a great start into February with carnival and Valentine's Day.

Am I going to meet you in Karlsruhe? Please make sure to register.

Thoughts on how to move from Cloud Functions to Code Engine

Moving code and containers
IBM Cloud Code Engine is a fully managed, serverless platform to (not only) run your containerized workloads. It has evolved a lot since March 2021, the time when I published the blog post Migrating Cloud Functions Code to Code Engine. In 2021, there were only Code Engine apps and jobs. Earlier this year, Code Engine added support for functions(Function-as-a-Service, FaaS). Thus, in this post I am going to take a fresh look at that topic and discuss the options on how to move from Cloud Functions to Code Engine.
