I like to use the “other view” feature of Notepad++ to show two files side by side. As I often have compare them I really like the synchronized vertical scrolling option which scrolls them both at the same time. There’s an icon you can click, but I prefer to use a key binding to toggle it.
As I really prefer Python for my little projects over C++, I flashed my Wemos boards with Micropython and wanted to share how I did it (it was pretty easy). You have to connect your board with USB to your computer, have Thonny installed and the desired micropython image downloaded. (You can do it with…
Yeah we all can loop, but can you any or all? Checking if condition matches for at least one element of an iterable (e.g. list, tuple, set) In Python you can write that nicer with the builtin method any(): But who doesn’t like a one-liner (that is understandable): Very similar is the case if you…
I wanted to know which topics are active on my MQTT server and if there were some skeletons in the closet I could get rid of. Many Iot devices, Node-RED flows and surely some unused topics or old retained topics lead to more or less MQTT being a chaotic museum of topics. This is just…
Precondition: Have your lokal MQTT broker and Node-RED installed and setup or access to a remote one. I recently added a http request node querying a weather API to Node-RED. After extracting, the current temperature is then published on the local MQTT and can be used by all devices connected to the broker.In this example…
“I didn’t change anything and it (the SSH console) just kept on freezing”.This sound like something a callcenter agent would hear many times a day. Not that I ever worked shifts in the night and early on weekends and got paid really well posing as some who knows more than the computer screen in front…
Most of my Raspberry Pis run headless (just remote console, no GUI). To remind myself and for your service I wrote this short memo how to set them up correctly. You can also find the same and much more Pi related information here, but I like to keep the stuff I need together in one…
