My isp gives me something a public ip like 200.191.57.xxx, but that ip changes and I can’t open any port. Then my isp’s router’s local network is 192.168.0.xxx, my TP link router connects there (to 192.168.0.3 i think). Then my TP link manages ips 192.168.1.xxx. My jelly server is at 192.168.1.10, my devices are at 192.168.1.5, 8, etc.
Everything is local, nothing goes outside
You’ll get better with practice. When I started with my Corne i was typing at 5-10 letters per minute the first week. After a month of practice I reached around 50 wpm, and hit a ceiling of ~90 wpm.
Speed should be a metric, not a target. It should be a side effect of using a better keyboard, so don’t focus on speed. Instead focus on accuracy, and learning exactly where each key is.
