Let’s Talk!
Suchen Sie einen zuverlässigen Partner, der Ihr Projekt auf die nächste Stufe bringt? Ob es um Entwicklung, Design, Sicherheit oder laufenden Support geht – ich würde mich gerne mit Ihnen unterhalten und sehen, wie ich Ihnen helfen kann.
So you want to set up email on a subdomain. Maybe you’re trying to route support@help.yourdomain.com to your helpdesk, or you want newsletters@mail.yourdomain.com to run through your ESP without torching your main domain’s reputation. Whatever the reason, you’ve landed on the right page. MX records for subdomains are one of those DNS topics that seem […]
I remember the absolute headache of managing local PHP environments a decade ago. You had a single global install, and testing a legacy application meant totally breaking your modern projects. We all reached for tools like PHP Brew to compile different versions from source, or VirtPHP, hoping for a Python-like virtual environment experience. Today, those […]
If you have ever embedded an audio player on a podcast site, a music portfolio, or a media archive, you have probably noticed that pretty rendered waveform behind the playhead. Libraries like Wavesurfer.js and Peaks.js can draw those visuals on the client, but decoding a 60-minute MP3 in the browser is slow, memory-hungry, and unreliable […]
Here’s a question that’s been bouncing around dev Slacks and SEO Twitter for the past year: should you bother serving Markdown to AI agents and crawlers? Is it actually worth the effort, or is it just another shiny standard that’ll quietly die like so many before it? Short answer? Yeah, it’s worth doing. The longer […]
Managing multiple social media accounts is exhausting. Between juggling different platforms, scheduling posts at optimal times, and keeping up with analytics, it’s easy to feel overwhelmed. Commercial tools like Buffer and Hootsuite work well but come with hefty subscription fees and feature limitations. Enter Postiz – an open-source, self-hosted social media scheduling platform that puts […]
Your server is being probed right now. Not maybe — definitely. Every public-facing IP on the internet gets hit by automated scanners, brute-force bots, and malware C2 callbacks within minutes of going live. The attackers aren’t targeting you specifically — they’re running scripts that sweep the entire IPv4 space on a loop, and your server […]
Updated: 03/2026 When I first put together the open-source KPI roundup back in October 2025, the landscape was already impressive. Fast forward to early 2026 and things have moved fast — we’re talking major version releases, AI features landing in free tiers, and a couple of genuinely exciting new tools that deserve a spot on […]
FEATURED: Best Server Hosts in Europe 2026: The Ultimate Guide A lot has evolved since I shared my top Docker picks in 2025. I’ve streamlined the whole setup, cut the noise, and focused on what I actually use — locally and externally. Better organised, better documented, and somehow more enjoyable than ever. Could not stick […]
Spam hasn’t gone anywhere. Keep coming back to it, as I hate cleaning up my INBOX and so do my clients! In fact, AI-generated spam has made the problem noticeably worse through 2025 and into 2026 — it’s more convincing, passes basic heuristic checks that would’ve flagged template spam instantly, and arrives in higher volumes. […]
Quick Answer: Modern developers have a rich ecosystem of dummy data tools — from classic Lorem Ipsum text generators and Lorem Picsum image placeholders to powerful libraries like @faker-js/faker and Falso, plus self-hosted Docker mock API servers like Mockoon, Smocker, and JSON Server. Let’s be honest — every developer has been there. You’re building a […]
