Deutsche Post ≠ Deutsche PostPost in german language / Artikel in deutscher Sprache

Wednesday, February 24, 2021 at 5:42 PM UTC
Ich musste knapp 49 Lenze alt werden, um zu lernen, dass die gute alte Deutsche Post nicht mehr existiert. Nein, wirklich nicht. Es gibt sie nicht mehr. Es mag Leute geben, denen das bekannt war, mir jedoch nicht. Was ich wusste ist, dass es neben der Postbank (Deutsche Bank) und DHL (Pakete) ja auch noch die Briefzustellung gibt, und die war, ist und bleibt für mich eben "die Post" [...] 

It's 21 and we are on to 12 #dominoforever

Wednesday, February 17, 2021 at 7:12 PM UTC
I love using click-bait-ish titles, right? This one addresses the year we're now in and "12" of course is referencing the version of HCL Notes and Domino which is currently under heavy beta testing around the globe. HCL just released the second iteration of it to the public. If you are not registered to the beta forum to give fee [...] 

Happy Valentine - or not? #dominoforever

Monday, February 8, 2021 at 8:20 PM UTC
Ok, this has nothing to do with Feb 14 aka Valentine's Day. I chose this title as my Let's Encrypt certificate for this page was going to expire on exact that date. I recently saw it and just now retweeted the Tweet of Detlev's blog post regarding the updated Let's Encrypt certificates that you have to add to your cacerts on Domino to [...] 

Using custom client certificates on Domino? Attention!

Friday, January 29, 2021 at 9:33 AM UTC
I have a customer who uses our Aveedo platform for a banking application. This application utilizes a REST service of a nationwide service provider for banks. To use these services you need to use a client certificate. Usually this client certificate is issued individually for each single bank. Our app has Java code that does the HTTPS calls to the REST endpoints of the service provider to gain [...] 

Fixing the ESP8266 on macOS

Sunday, January 17, 2021 at 11:34 AM UTC
I am tinkering with smart home for a while now and before Christmas I remembered that I once used to be an electronic technician - that's more than 25 years ago. However, I wanted to refresh some of my skills. I got the right tools now and so I wanted to dive into the world of Arduinos. I got a starter kit 5 years ago from my company as an Advent calendar - but didn't to anything with it. [...] 

ioBroker wins: goodybe, Phoscon app

Sunday, January 3, 2021 at 5:00 AM UTC
A few days ago I decommissioned the Phoscon app to control all my Zigbee devices. The reason: it's buggy as hell. I only changed some bulbs and renamed existing bulbs in the same room - and suddenly the switches associated with the former bulbs started to go crazy and and switched sockets that never were a part of that former group/room. I also did not like the UI of the app at all. Since I [...] 

The Phoscon app and switches

Saturday, November 28, 2020 at 7:10 PM UTC
Today I noticed a weird issue using the Phoscon app. For all who are not aware: this is the software that is used to setup smart stuff on the Conbee Zigbee gateway. Every time you add a new switch, it will create a new group. Depending on the device type the group's name is different. I was at IKEA today to buy a LED panel (FLOALT 30x90) for the ceiling in one room and I also bought 4 sw [...] 

Nope. The MBP 16" 2019 still sucks

Saturday, November 28, 2020 at 12:22 AM UTC
Remember when I thought my issues with the MBP 16" were history after the macOS 11 update? They are still there. This machine is unusable once you do one of the following: try to tame the crazy fan with Macs Fan Control use Teams/GotoMeeting with a webcam AND sharing your screen in general use external monitors and try to outperfo [...] 

Zigbee, Homekit and a Pi

Wednesday, November 25, 2020 at 7:05 PM UTC
Today I decided to note down my experiences during my journey setting up various Zigbee devices with Apple Homekit. There are several steps involved. As I wrote them down in markdown, you can find the document on my Github account here. [...] 

Moving Domino to a container

Saturday, November 21, 2020 at 8:07 PM UTC
Today I successfully moved a Domino server from a native installation on a non-supported Linux to a docker container. It actually wasn't really a moving as I installed a different server version. The original server was V11 and the containerized one now is of course the latest code drop of V12.  I used my own guide to create the new container, copied over the existi [...]
