cisco sfp issues
https://community.cisco.com/t5/switching/cisco-disabled-1gig-support-on-9400-x-sup2-starting-with-17-9-1/m-p/5216471#M572370 rt interest it’s interesting that Cisco branded sfps have this limitation. Meaning somehow the switch knows more about the Cisco SFP and a non Cisco SFP. I kind of wonder about Cisco being the king and gorilla of the networking world. They just have a lot of competition now and Nvidia is ruling withContinue reading “cisco sfp issues”

windows installer exploit
I went through this again, trying to figure out what exactly is going on with the windows installer. It seems to me this is an exploit of the windows installer as much as an exploit of an application. The details of how the windows installer works gave me a few insights.

I would like to try one of these new PC’s. They run windows but these are NEW as they have ARM CPU instead of the normal CPU that you would have in a laptop.
