am i missing anything?

My mouses right button kept double clicking. This makes it really hard to play minecraft. It was a cheap logitech mouse from a wireless keyboard/mouse combo. So I went to the store to find a new one. Almost all the wireless mice were gone. Apparently WFH people hit walmart. I didn't want another single wireless mouse. This would mean I need the adapter for the keyboard (for keyboard mouse combo) and the new mouse plugged in. My computer is a laptop so there are not a lot of those slots. So I looked for a bluetooth mouse. Only one there and it was a sucky Razer. I have not liked Razer since they required people to register their software with an account before using their drivers. This really made me avoid this brand like the plague. So I finally settled on a wired gaming mouse. It has a nice long 6ft cord so it works with my setup. It is a G502 Hero. It works really nicely without drivers. I will be testing with drivers tonight. I usually buy el cheapo mice so this is new to me. So far so good.

I'm just dumping 10 GB of data remotely from a mysql db, because my el cheapo VPS run out of space

can you suggest a good book?
oh, actually I already found one, the title is "Prepare your fucking server/workspace properly if you want to play around with a lot of data"
