HerrlichDigital··on Fly.io 2026 Pricing Update
Let's see if this affects my setup. But maybe there are more tweaks i can do to cut costs if it rises to much. In the past i moved from a managed PostreSQL from fly.io to a self hosted version on a fly.io machine and it saved me around 30$ a month.
HerrlichDigital··on Ask HN: What self-hosted apps do you use daily?
I'm also running a Home Lab with several useful projects:

- Nextcloud (Cloud Storage alternative)

- Home Assistant (Awesome Smart Home Platform)

- Calibre-Web (Managing my eBooks)

I also run Umami but on a fly.io instance with all my other software that i build as a solo preneur.

HerrlichDigital··on Show HN: I built a new version of my fun spatial 3D online meeting app
Really nice Project, I'm working with WebRTC my self and i struggled with different things that cause the problems mentioned in the comments. For example Safari has some weird WebRTC quirks (getUserMedia/codec differences vs. Chrome) further more the stutters are often scaling problems and not because of the rendering. And i have seen in my analytics for my App https://sharry.live that there are often connection problems because of restrictive network settings which can be handled by a TURN Server.
HerrlichDigital··on From MySQL to PostgreSQL: a much lighter server
Is it really that easy to migrate to another DB Engine? I moved from managed PostgreSQL from fly.io to self-hosted PostgreSQL on a fly.io instance for my umami analytics, and it saved me $30 a month. But i haven't switched the Engine from MySQL to PostgreSQL.
HerrlichDigital··on Ask HN: My recent show HN post got flagged need guidance
I got the same problem with my posts and comments. They were flagged, which was obvious for me after i activated the "showdead" option in my profile, or they got marked as "shadow-dead" and I only found out via the public JSON API. "Shadow-Dead" means, for me, everything looked okay, but no one else saw my post.

After that, I asked an HN Mod what the problem was, and they thought my posts were created by GenAI, and because of that, they were flagged. And he gave me the advice that I don't use GenAI at all for HN, not even to polish my crappy text.

Hope this was helpful, wish you a good Day

HerrlichDigital··on Show HN: My local climbing gym from photogrammetry
Wow this is a great idea and I wish my local climbing gym had something like that. Maybe it is a good idea to put a help section for every route and visualize this.
HerrlichDigital··on Show HN: How will the Aug 12 eclipse look like from your address?
And I live near Düsseldorf so I think the percentage fits to my place.
HerrlichDigital··on Show HN: How will the Aug 12 eclipse look like from your address?
I think I will stay at home and watch the partial eclipse from their. But I think I need to go upstairs to my attic and watch it from a window up their.
HerrlichDigital··on Show HN: My WHOOP has no screen. My Kindle had no job. So I put them together
Awesome idea, I'm not a woop owner but I love the idea to repurpose old tech and use it for other things instead of throwing them away.

Nice idea, I heard of the new designs for the euro bills but haven't seen them. You site is an awesome place to see them, many thanks
HerrlichDigital··on Show HN: An enjoyable and efficient way for product teams to communicate
This is an awesome Idea, I would love to use it in the future but currently I don't have a team anymore and try my way as a solopreneur. But I will have it on my radar and will see maybe in the future I need a tool like this. Keep up the good work
HerrlichDigital··on Show HN: How will the Aug 12 eclipse look like from your address?
Many thanks I will take a look at the new data about German cities.
HerrlichDigital··on Show HN: How will the Aug 12 eclipse look like from your address?
Awesome I was wondering how and if I will see it here in western Germany. Have seen a solar eclipse in the 90s and I wonder if it will be the same experience. Many thanks for this tool.
HerrlichDigital··on Apple should let us schedule work-hours notifications for specific apps
Sounds like an excellent idea and I would love to see this in Android as well. Easy way just general for all apps and for more advanced users would really be nice to do it for each app individually.
HerrlichDigital··on Qwen 3.8
I used Qwen before, and I'm pretty curious what the new version is all about.
