Hi everyone,
First post here, trying to showcase mining software as part of a school final project. (DISCLAIMER: I understand mining BTC with a CPU is absolutely worthless, this is for informative/educational purposes only)
I've setup minerd.exe to solo mine with the following command:
minerd.exe -a sha256d -o
http://127.0.0.1:8332 -O user:password --coinbase-addr=xxxxxxxxxx
The output I get in cmd is this:

[2022-05-15 03:32:04] LONGPOLL pushed new work
My question is, what does "LONGPOLL pushed new work" mean? I can't find it in the documentation for cpuminer.
Some results on the web show it is to inform the network a block has been found, so that work is stopped on solving the current block and started on the next (to avoid wasting time), however i noticed that in some other threads about LONGPOLL, the message says "Stratum detected a new block", "LONGPULL detected a new block". Could someone kindly explain the difference between these three? (LONGPOLL new work, vs Stratum detected new block, LONGPOLL detected a new block etc...even if the answer is pretty self-explanatory in the name).
Lastly, I am making a slide comparing pool mining vs solo mining. It's been about a couple of hours since I started mining and no share has been submitted for this f2pool I am experimenting with. (could someone verify if this cmd command is correct? the worker is not showing up as generating work on the f2pool website).
minerd.exe -a sha256d -o stratum+tcp://b4c.f2pool.com:1228 -O account_name.worker_name:password --coinbase-addr=xxxxxxxxxxx

Greatly appreciate all response/suggestions.
Thanks!
