I could use the time “between the years” to educate myself in a topic that I wanted to understand for a longer time: Docker.
Last year, I bought a book about it, so I knew it is something about containers and portable, scalable software development tools, but as long as you haven’t really put your hands on it, you don’t really know what’s going on. Luckily, there is a very good tutorial, directly delivered by docker.com: https://docs.docker.com/get-started/ that I played through in the last days.
I have to admit: I am pretty deep in the Apple universe.
Since I bought an iPad 2 for my studies, I am a big iPad fan. The portability of the device is just crazy, when I think what I can do now with my iPad Pro, that’s just incredible. For some travels, I can even leave my notebook at home because my iPad is covering the tasks that I need. Combined with the HDMI adapter, I can even do PowerPoint presentations, the Pencil is just amazing to review and comment documents that are sent to me.
An important component for that is actually Office 365 which enables me to access all my OneDrive-documents while on the road and edit them with Word, Excel, PowerPoint. I know I’m just writing down the marketing words, but it really works well. Of course, here is also room for improvement, but in general: it works! Continue reading “Siri, where have you gone?”→
Let me say something about my first days with the new Apple Watch 3.
I was one of the early adopters when the first Apple Watch came out last year (yes, it was only 2016 when I bought Apple watch 1!) Back then, I was of course proud of my new gadget. At that time, you still felt like a Gadget-nerd when you had one of those smart watches. End of 2017, that kind of changed, no one is wondering why your watch is not showing the time anymore if you don’t raise your wrist, so your motivation to wear the watch should be another one.

The reason I made that effort in understanding Spring is that a colleague of mine, who is Java developer, recommend Spring for our brewcloud-project because it is a lightweight way to create a Java application easily.
But before it gets easy, you have to understand some Spring basics – I tried to write some of them done in the article I linked above. Continue reading “deploying a Spring application on SAP Cloud Platform”→
I did my first steps with a Spring Boot application and now, I need to extend the bootstrapped start application for my individual needs. So I need to understand a little bit more about the inside of a Spring application in order to make changes / extensions – I would like to take some notes about that here!
My first finding:
“In Spring, objects aren’t responsible for finding or creating the other objects that they need to do their jobs. Instead, the container gives them references to the objects that they collaborate with.” (source: book: “Spring in action” by Craig Walls)
