On my way creating my own solution regarding doorbells, homeautomation, SIP and stuff I stumbled onto a problem because "Could not initialize class org.codehaus.groovy.runtime.InvokerHelper" The answer: The Flutter Android project is initializing the Gradle settings with version 5.6.2 and this i…
Hey hey, during this strange times I thought minutes and hours about how to code something useful. Well it ends up in a small bot which is scraping the official Covid infection number page of Hessen and post the result to every person who chats with the bot. He's called the "CovidHessenBot". It's a…
So, one of my small-inbetween-projects was to "hack" a 20€ IP camera which I bought on eBay. However it was not that easy as I destroyed the first UART connector by just wiring it wrongly ;). At least I've managed to create some kind of custom firmware which starts a sshd, a ftpd and disabled some,…

Sadly I broke an image in the flash so I had to sideload the backup - which I've luckily created beforehand - back to the device. I've searched for a solution to it using Windows and found two tools worked together. The…
sigh sometimes I hate this adminstration stuff but it was necessary as I'm migrating stuff to containerd version. This time I choosed to spend my time in migrating my existing nextcloud installation to the docker version (and upgrading during this process (everytime a great idea)). However I ended u…

During my first steps in develop some Flutter apps I came across - as always - the requirement for adding internationalization. In Flutter it's a three steps way to go to have i18n in your widgets. First of all you have to create a class to present your strings to the widget, then you have to run a…
I know, there are various posts about how to integrate D3 into react components like this [https://medium.com/@Elijah_Meeks/interactive-applications-with-react-d3-f76f7b3ebc71] or this [https://www.smashingmagazine.com/2018/02/react-d3-ecosystem/]. If you try it naively you'll face the problem of h…
Want to have time strings like "n seconds ago" or "m months ago"? Here's a short script. export function friendlyTimePassed(targetDate) { let timeDifferenceMilliseconds = new Date().getTime()-targetDate.getTime(); const ms = 1000; const min = 60 * ms; const hrs = 60 * min; const…
