Can't libre office's calc work with Excel files?

Yeah. I had this problem. I ended up switching out the WiFi module for one with better Linux support. (In my laptop it's just a little m.2 thing).

The simplest and slowest way when you need to use something from the system clipboard:

Copying: Enter visual mode (v) Highlight the text I want to copy then enter in command mode "+y which basically means "Use a register for following command (") make it the external clipboard register (+) and yank/copy (y)"

Pasting Move to where I want to paste then enter in command mode "+p to paste after the current position or "+P to paste before the current position

If I don't need to copy/paste stuff to applications outside of vim, then I can skip the "+ register setting part, and just use the default internal register.

Well, being open minded doesn't mean you won't reject something, just that you won't reject something without mulling it over first. I'm sure their desire to not want to create account is not a flippant remark and a position they arrived at over time.

Another alternative, I've been looking at is radicle. It's private repository stuff is rough, but public repository stuff, much less so. Seems to be early days but I really like what the project is doing.

Ultimately you get something interesting out of rofi by creating scripts that call it every time a user needs to select something. Your Reddit example would be trivial to do, at least core functionality wise, if not exact key presses.

Right, but you can have entries in a block chain that indicate previous entries are no longer valid, or have modifications. Calculating a final state by walking through all the blocks in the chain. ( A bit like a CQRS based system can have a particular state at a point in time by replaying all events up to that point)

Doing it in such a way also makes auditing what's happened much easier since changes are inherently reflected in the chain. You want to know when (or by who if you keep that information) a record changes, it's right their in the chain.

Well from their site

Moderation

Since there are no global admins, the administrative control of a subplebbit rests solely with its creator. No one else can moderate content or accounts unless the subplebbit creator grants them permission.

So, it's not that there's no moderation. It's just "subplebbit" creator/delegates controlled as there is no over arching site wide company able to moderate it on the whole.

It will mean, as a user, you'll have to be liberal with removing subplebbits from your own feed though. I'm sure there will be some.. not so pleasant subplebbits appearing.

If you are on Linux locally, you could try using sshfs, to "mount" the remote system to your local one and use your local dev tools. Though I suspect that would be against the spirit of what company is hoping for.
