Mastodon is how the Web should be: OPEN

TL;DR: just add “.rss” to a mastodon profile or tags or user-tags to get an RSS stream! My photography profile @hikingdude@mastodon.social for example can easily be followed by an RSS Reader by following https://mastodon.social/@hikingdude.rss.

No account required! And that’s not even the end! 🤯

How to get rid of Cookie-AdTracking – easily

TL;DR: Delete cookies when closing the browser, allow-list only the sites you want to stay logged in. It’s really that easy.

I recently checked my browser settings and was “surprised” to find more than 3.000 cookies. Most of them from sites I didn’t recognize, many from obvious ad-tracking companies. These companies, with whom I have no business, were all able to track my online activity. Seriously? 3.000 companies being able to track me? Okay maybe some of them were not valid anymore – but still – that’s just ways too much.

Making the Best of a Bad Presentation Experience

Recently, I attended a conference and sat through a particularly bad presentation. I was tempted to leave, but my colleague insisted we stay until the end. So I somehow had to make the best out of it. This gave me the opportunity to analyze what made the presentation so ineffective and “bad” for me (maybe it was interesting for other people, I just didn’t like it.

So I regarded it as a case study to probably improve my own presentations.

Good Conference Talks aren’t just Success Stories

Recently, my colleagues and I attended the World of Data conference. (The conference is an event in the data and analytics industry, where latest trends, technologies etc are presented in workshops and talks/presentations. It’s pretty nice to be honest!)

Good bye posting on LinkedIn?

“Why am I posting on LinkedIn?”

That question recently just came to my mind.

My inital idea was to change from LinkIn posting to posting on another, work/IT related Mastodon-account – just for the sake of getting off a commercial platform. But then I started asking myself the “whys”

How to filter / hide / ignore News in an RSS feed

Recently I realized that there are certain topics in my news / RSS feed that I ALWAYS scroll over. I’m just not interested in them. Like news about certain brands, manufacturer or products. I wondered, if there is no easy way to simply NOT see them in my feed. I mean I filter by only looking at keywords in the title. Really super simple.

How to fix: Jabra Elite 75T volume too low / decreasing

Problem: Recently I faced the issue with my Jabra Elite InEars that while I was using them, the volume started to continually decrease until I had to max out the volume on the phone. Yet the sound was still barely loud enough to hear it. After not using them for a while, sound was okay again (still quiet but better) until volume started to decrease again while using.

The internet is FULL of advice about Bluetooth settings, resetting the phone, entering developer mode etc. Yet it was ways easier.

How to Exclude OpenAI GPTBot from future crawling a website

In order to tell OpenAI to stop crawling a website and thus not use the content for training GPT, OpenAI now supports to disallow GPTBot from accessing your site.

The Information can be found on the GPTBot – OpenAI API website:

Allow/disallow certain parts of a website:

User-agent: GPTBot
Allow: /directory-1/
Disallow: /directory-2/

For WordPress sites, I can recommend the Virtual Robots.txt – plugin.

How to fix: Jabra Elite 75T different volume of in-Ear headphones

I often just use one of the in-ears of my Jabra 75T. Recently I figured out that when I use both in-ears headphones, the right one was significantly louder than the left one. After a quick hearing test, I was convinced that it is not a problem with my hearing but with one of the headphones.

After some back and forth, the easiest solution was:
Simply hard reset the headphones in 2 simple steps.
If resetting does NOT solve the issue permanently: Try cleaning a specific part!
