After some days I revisited a project I have been working on for ages, and for some reasons it welcomed me with this error: javax.faces.el.EvaluationException: java.lang.ClassFormatError: JVMCFRE113 unexpected EOF; class=de/mekos/MekosUtils, offset=0 at com.sun.faces.el.ValueBindingImpl.getValue(ValueBindingImpl.java:184) at com.sun.faces.el.ValueBindingImpl.getValue(ValueBindingImpl.java:134 [...] 

I am not at all into cars, but today I had to say "farewell" to my old lady I spent the last 15 years with until the TÜV us do part (TÜV = technical check department). It happened last week. I checked out a new (used) car then, bought it and today acquired it finally and here it is. Again, a Czech car which I am very satisfied with again. The Octavia is the most popular [...] 

Since I always forget about the timezone settings when spinning up Domino in a container, I just wanted to document it here for my own records. The key here is to provide an environment setting directly when issuing the run command. For me this would be the Central European timezone like so: docker run -d --name domdev -v /local/notesdata:/local/notesdata --hostname domdev.local --cap-add=SYS_P [...] 

Today marks my 25th anniversary working in the IT industry and esp. with a product which once was called Lotus Notes and Lotus Domino. My first contact was Notes 4.5.x which came with the Designer part integrated, not as a separate app. It was fast. Holy cow, how fast it was! I made my first certificates using the brand new version R5 (“Super Human Software”) and one year later in N [...] 

It’s 2025, I was thinking about a new webcam. I was using a Microsoft (!) 1080p webcam for ages and it’s crap - esp. on a Mac. I had to use a utility called WebCamSettings to get this even working with Teams etc. Webcam My decision was buying a “real” webcam like an OBSBOT or an Insta 360 Link. These are not cheap and these are “only” webcams. Since iPhone [...] 

In my recent post I mentioned a new (beta) voice assistant device for the use in your Home Assistant system. There are others available on AliExpress based on ESP32 etc. but this one is "the official". More information here. Today it was delivered. Yes, it is not the sexiest device on earth, it attracts dust as crazy and I absolutley want to hide it (and you could because mics and spe [...] 

This post is about on how I managed to transform my Smart Home from using vendor-based solutions to open-source and local-only systems. I am actually cheating. Although my solutions work entirely local, the fact that I want to use it remotely, also requires a cloud account to access it, namely the Nabu Casa account which is 75 bucks per year. Where I came from My first Smart Home steps based [...] 

I recently started to use TickTick, a powerful app to track your personal tasks, reminders etc. I am using the Mac version which introduces a keyboard shortcut to quickly startg a pomodoro timer. The problem is: the same shortcut is used to open the command menu in VS Code: SHIFT+CMD+P VS Code stopped to react on this one and it took me a while to figure out the reason, so here is how to dis [...] 

Today I again encountered some strange things on different Domino machines. It’s Java again. The other specs are: my local dev box is 12.0.2FP2, running in a container using the HCL image the other machines are natively installed 12.0.2FP2, also Linux there are no language packs installed at all The parts that are used: some Java in an NSF, defined as managed bean (but t [...] 

I am done with social media in general. Facebook is only usable with the genius browser plugin FBP. It is just my birthday calendar for my contacts I don’t maintain a “real” record in my phone or anywhere else. Twitter/X always only was my news feed. If you don’t like the political bias here just do not read the comments and block accounts you don’t like - so ea [...]
