How to make ActivityPub plugin publish WordPress posts

In general it should be super simple to federate WordPress posts to the fediverse: Just simply install and activate the ActivityPub WordPress plugin and there you go.

I activated the plugin in two WordPress installation. In one it worked like a charm in one the federeation simply did not work. I aslo asked at the ActivityPub Support on WordPress.org (and checked Cron logs etc). Nothing helped.

Then, one day I found the solution: The Site URL / Domain name must be all in small letters. On this blog, I had the site URL = www.Locked.de. As soon as I changed to a small “l”, federation worked like a charm.

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 recognize them 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.

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:

Completely disallow GPTBot:

User-agent: GPTBot
Disallow: /

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.

AI Text Generation and Blogging: How AI-Assisted Writing Can Revolutionize Your Blogging Experience

Blogging has become a popular platform for individuals and businesses to share their ideas, opinions, and experiences with the world. However, blogging just occasionally can be a challenging task. It requires getting into the writing flow, writing cohesively throughout an article, crafting a proper introduction, and ensuring the use of correct grammar and vocabulary. For non-native English speakers, it can be even more challenging to write in a language that is not their mother tongue. The lack of proper vocabulary, grammar, and sentence structure can hinder their writing ability and prevent them from expressing their thoughts effectively.

AI Image Generation and the Future of Photography and Graphics Industry

Artificial intelligence (AI) has been transforming various industries, and the photography and graphics industry is no exception. With the development of AI image generation tools, it is now possible to create realistic images that are indistinguishable from those captured by a camera or created by a human designer. While this technology holds immense potential for businesses in terms of cost and time efficiency, it will also bring about significant changes in the industry and its related sectors.

An advantage of remote interviews

There have been plenty of articles and comments about the (dis)advantages of home office vs in-office scenarios over the past two years. One critical aspect of home-office is definitely about creating a personal relationship with people that you never meet in person.

One situation where a personal relationship is quite important is an interview with candidates (be it internal or external). Besides the technical expertise you also want to know whether or not the candidate is a fit for the team. In the past 2+ years, we interviewed dozens of people for positions in the team. I say “we” because we usually are 2-3 internals holding different positions in the team (dev, ops, product owner, …) interviewing the new candidate. And in the past 2+ years we did all those interviews remotely via video-conferencing.

My critical view about “the Metaverse”

Recently the term “Metaverse” is across like in every IT related news. Noone really knows what it is but it seems to be the hot shit you have to be into! And it seems to be THE ultimate solution for so many odd problems AND a totally new business market!

The “metaverse” topic has followed me now a couple of months and I had a couple of discussions already about my critical view about the topic. And if it was worth discussing so often – it might be worth writing it down as well. 😀

Compensating time shift / Changing File Creation time using Windows Powershell

I don’t want to blame the time shift 2x a year. At least as long as I do not forget to change the time on my camera as well! As I am doing most of my photography on hikes and geo tag them afterwards, It makes quite a difference if the file creation time is right or wrong.

This year I forgot to change it on the camera and needed to bulk-change the file time later. Luckily this is pretty easy using Windows Powershell and the Windows PowerShell ISE (Integrated Scripting Environment):

$files = Get-ChildItem "C:\Users\[....]\*.arw"
foreach ($f in $files){
    $d1 = [System.IO.File]::GetCreationTime($f.FullName)
    $d2 = $d1.addHours(1)
	[System.IO.File]::SetCreationTime($f.FullName, $d2)
    echo $d1 
    echo $d2
    echo ---
}

Just copy it into the ISE, execute, done.
