Game Streaming: Full Circle

This is just a quick entry to wrap up my adventure with online streaming.  It started like anything does: with nothing but an idea.  I wanted to see if I could understand and figure out the technology behind streaming.  I started on YouTube because they allow a near infinite upload bandwidth (turns out: it’s 51Mbit/sec) which made it possible for…

Automating Cumulus With Ansible and ZTP

NVidia 4K Display Limits: Card Bandwidth?

Good luck struck me recently and I was able to get my hands on the brand new Asus ROG Swift PG27UQ display.  This 27″ LCD can do 4K at 144Hz and features NVidia’s GSync technology.  It’s not an inexpensive display at $2000.  Nor is it readily available yet.  I was fortunate enough that my local Microcenter had six of them…
