The whole idea to check the donations came from stumbling upon this post which discussed costs per user.

Things should be put into perspective. The cost per user is actually the fixed monthly cost of operating an instance divided by the average number of active users.

In the discussion you linked to, there’s a post on how Lemmy.ml costs $80/month + domain name to serve ~2.4k users. If we went through opex/users metric, needlessly expensive setups with low participation would be a justification to ask for more donations.

Regardless, this is a good reminder that anyone can self-host their own Lemmy instance. Some Lemmy self-host posts go as far as to claim a Lemmy instance can be run on a $5/month virtual private server from the likes of scaleway.

Is there something else I’m not seeing?

Possibly payment processing fees. Some banks/payment institutions charge you for a payment.

From the blog post, it sounds like the underlying motivation is not tied to technical aspects but control over the language. If I had invested any of my personal time onboarding onto D and migrated any of my projects to D, I would be concerned about the negative impact these political stunts have on the tech stack.

The biggest news to me is that GitHub allows users to search code. Every single time I tried to search something in GitHub, search results were next to completely useless, and always a sure-fire waste of time and effort.

There’s hope, I guess.

Duplicate code can be a code smell, but it’s far better to have the same function definition or code block appear twice in the code than extracting a function that tightly couples two components that should not be coupled at all.
