Get ready for IDUG North America Db2 Tech Conference

In about a week (June 23-27), IDUG North America Db2 Tech Conference is going to start. Are you already registered and will attend either on-site or virtually? Agendas for on-site attendees and the virtual participants have been posted. 

"Breakfast Buffet Available" is something you only find on the on-site agenda. As I am to attend virtually, I will have to stack up food and drinks and get ready for an exciting week of technical talks related to Db2 for z/OS and Db2 for Linux, UNIX, and Windows.

Authentication for your IBM Cloud Code Engine functions

Protect your Code Engine functions
How can we protect an API function implemented as IBM Cloud Code Engine function? This was one of the questions which I recently answered. When migrating from IBM Cloud Functions to Code Engine, this is a common question. Cloud Functions offer some basic security to protect against unauthorized calls. Code Engine and their functions differ in flexibility and hence you have to deal with authentication. Here is a simple solution.

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.
