What's the setting here? Metric spaces?

comment Showing that an inclusion is null homotopic
@t.b. It's funny. Reading this I barely recognise my old self from 4 years ago.

comment Group of Unitaries: Strong Continuity
@Freeze_S Yes. The only exception that comes to mind now is when you post a comment on someone else's post like e.g. this answer. Then the author will get notified of the comments whether they include pings or not. No problem!

@Freeze_S Wonderful. Also note that unless you ping users with "@username" they won't get pinged and won't notice it if you replied. I only saw it because I came here to check.

@Freeze_S So why is the downvote still there? I'm going to make a trivial edit in case you don't have enough privileges.

comment Topology of uniform convergence?
I get it. Whoever wrote the Wikipedia article misuses "topology of uniform convergence" to mean "topology induced by $\|\cdot\|_\infty$". How terrible. This individual should be banned from writing about mathematics.

comment Topology of uniform convergence?
But the "topology of uniform convergence" seems to mean something different. Does it mean that the same word is used to mean two different things or does it mean that the "topology of uniform convergence" coincides with the topology induced by the sup-norm in certain cases?

comment Show that a space is separable.
@DanielRust But the product space does not only consist of continuous maps. What am I missing?
