I remember trying that, and just tried again.
There is an auto-reply that tells me to use the portal, which I cannot use because it asks me to log in, but since my account is locked...
EDIT: managed to create an account on support.gitlab.com

Q: Does anybody know why my account on GitLab would have been disabled, or what I could do about it?
I am building apps for Android to be published on F-Droid, and using GitLab is part of the workflow, so now I'm stuck.

I do not remember who posted this (maybe about 1 year ago), and I can not find the original post now, but I think about it often, and it is true.
(grateful for any pointers as to who posted this)

Really difficult to get my head around how conservatives and the right use the concept of individualism and egotism to get people to vote for things that are quite obviously not good for them.
I'm egoistic about public transport: I want it to be free.
For me, that is so incredibly straight-forward, I do not understand how people can not see it.

I only wish people were giving me more feedback!
It feels good when I get messages, be that here or via email, or in the repository.

Back in the 90s, when I built apps for PalmOS, I just put them out there, and apart from individual feedback, I never knew how many people were using them.
Then I started working in Web Analytics in 2008. Woah! Everything can be tracked! Knowledge!
That was cool for a while, but unfortunately as an industry, we took it a little far.
So, when I went back to building apps, this time on Android, I decided: no tracking.
I'm back in the 90s 🙂

The view of the Blauen this morning when I rode to work. It was cold (8C) but bright and clear. Spectacular, really!
30 minutes later, the fog rolled in, and we're now under a grey blanket. #MdRzA #BikeTooter #Commute

Sometimes, when I push up a steep bit of trail, my eBike makes unholy cracking sounds. LBS thinks it may be belt tension, so I spent the day trying to fix that.
Belt was "at 30Hz" when I started, and it should be between 40Hz and 55Hz. I managed to get it to around 52Hz or so. (Yes, I find it weird to write about tension in Hz) #eBike #BikeMaintenance

Infrastruktur, die funktioniert, und deren Ziel nicht "Geld verdienen" ist, sondern eben "funktioniert". #WasWirWollen

The weather has changed. It is no longer hot, and it rained for like 20 hours straight. But not this morning, and so off I went. #MTB #Fatbike #MorningRide
