Not outside of the US
Unfortunately it is relative. On reddit this probably wouldn't even be noticed, it would just likely be buried and never seen by the vast majority of people. Problem is people bring the same posting habits to Lemmy as they are used to on Reddit (opening lots of posts over multiple communities which is necessary in order to be seen) and it creates a lot of extra noise and perceived spam.
Jerboa, I've looked at a few but Jerboa was the first one and I've got used to it.
None of those by default, Pulsar tends to stick to being an editor with as much as you need but not more by default. However one good thing about forking Atom was that we kept all the packages that were published to atom.io (more than 10k of them). You can browse them the PPR (Pulsar Package Registry) which was reverse engineered from Atom's closed source backend from scratch before they took down the site - https://web.pulsar-edit.dev/.
Specifically there are a bunch of remote edit packages that work over SSH, a ton of Docker packages and there are plenty of debugging packages both generic and language specific and there are indeed test runner packages.
I won't say I guarantee all of these will work but our Discord channel in particular is rather active so people more knowledgeable than I might well be able to help out, its a friendly place. We have other social channels as well should you prefer them.
I know it doesn't tick the boxes but there technicality is a Microsoft made, open source, alternative to Explorer. The original File Manager for Windows 3.1 and it is still seeing active development. Just thought to bring it to attention for a bit of nostalgic fun but I actually find myself using it a fair bit.
I can't say I really use any of the older style BBS ones like phpBB but there are plenty of smaller software communities using Discourse based forums. For less active communities they are far superior to Discord due to the more asynchronous nature and gives you a lot more control than Reddit/Lemmy.
Really like tuta, have to admit that i've not looked closely at the paid options but they provide their services for free to our open source project and it functionality even on that tier is pretty great.
Kitty the vast majority of the time but slowly using Ghostty more and more as it improves. Sometimes use Tabby and have been looking into Wave recently. I also use the x-terminal-reloaded package in the Pulsar editor for a dock terminal if im doing something in it at the same time.
The Glory really had me hooked the whole way.
Pet boa constrictor died and started fermenting in the viv. It was like a wall of putrid stench. Had to get her quadrouple bagged and taken to the vets for proper disposal.
Lyra doesn't care so long as she has her box
