A problem here where I work is that every application must have a different password and it must change every 90 days. Consequently everyone has a spreadsheet with his passwords written down because nobody could possibly remember them all.
It seems to me that with 2FA, one simple password is adequate. Two independent devices need to be compromised and brute force is ineffective since the turn around time is at least several seconds between tries.
My guess is that - with email, both the sender and the receiver must be using clients that are capable of negotiating the challenge-response wall.
Interestingly, with phone service, the recipient doesn't need anything (other than to tell their phone provider to turn it on if it's provided as an option.)
Of course, this doesn't completely answer your question but it does mean that the decision and implementation of the technology needed to provide this kind of wall is in the hands of phone companies rather than the unruly mass of ignorant individuals who use email.
But then, the phone companies who could implement such a scheme probably don't have a financial incentive to do so.
I'm not an archer of any rank. But my take on this is that he's trying to represent or reproduce the skill of archery when archery was essential to war and hunting. Great skill in an Olympic competition is certainly an impressive achievement but it may be worthless outside the clearly defined rules of competition.
Between your 120 bowman and this guy, which one wins in battle and which one brings home fresh meat for dinner. I think I'd rather have this guy on my side.
I've been walking at lunchtime for over 10 years. For some reason, co-workers think they're being friendly and companionable when they come along. I hate hearing the cheerful: "Hey I'll come and walk with you."
NO. That's my time to be away from you guys. I use that time to think about what I have to do in the afternoon, what I need to include in the report that I'm writing, how I'm going to fix the sticky door in the basement, or what I'm going to get for my wife for her birthday. I don't want to discuss the merits of partially deflated footballs.
I find that I have to sneak out the door when nobody is looking.
I was assume that this was part of a structured bill of materials. Changing the rev level should be sufficient to identify the change and would not entail changing the BOM.
I'm going to make a strong guess that the rev level was incremented (the article doesn't mention rev levels). If so, I don't see anything wrong with using the same P/N. It's not like that part number exists elsewhere in the vehicle.
