Wrote this piece for the @PressHerald where the cyber policy guy steps out of his lane and into urban planning because stepping off the curb has become so dangerous. pressherald.com/2025/04/08/opi…
I got a guy who can find you the perfect spot and get it built out -- hit me up
Cumberland County also has about the same population as Iceland -- where you have a service center and your business is blowing up
Despite the two hour drive from Portland, our largest city, to the nearest service center in Peabody, MA, there are 2,100 Teslas registered in the state; over a third (800) are from counties that are 2+ hours from Peabody.
Please dear god put in a service center -- rumint has it you canceled plans to do so a couple of years back
I live in Maine, a state with 1M cars, 1.3M people, and a well built out charging network just waiting for my more BEVs (26 BEVs per 1 DC charger vs. 60 in CT)
You’ve already rolled one truck to confirm that the modem is functioning and now you are going to send another
@FidiumFiber I can’t believe I am doing this but I just signed back up with @GetSpectrum because your tech support is so terrible; on Monday, I swapped a plug and play router — why you require a phone call and a verbal confirmation of the new MAC address is beyond me
Are others hearing that insurance companies in the US are starting to exclude ransom payments? Have not heard or seen that directly but was just told that through a long game of telephone...
@CarpeDiemCyber agreed -- power companies that rely on them are the first to say that albeit quietly.
@CarpeDiemCyber never let a crisis go to waste... TSA had long taken the position that regulation was not necessary. Clearly it is, if only because absent regulation government only finds out whether security is poor when something bad happens.
If I were to write an inside baseball article on how to fix fedramp, where should I try and get that published?
