This is the same tech refresh upgrade every big bank is in flight doing.
Using simple magnets the windows could self clean in the same way someone can clean the inside of a fishtank
Bitcoin for all its technical sophistication is more of a threat to "stock exchanges" or "equity allocation" than it ever will be to "currencies"
It is not suitable to a "drive-thru" transactions due to the number of "confirms" required to have veracity in the exchange.
However, it is VERY WELL SUITED to the exchange of equity -- and is, given the current settlement times, much more of a threat to public ledgers like TORRENS (property exchange logs) -- or stock/ownership exchanges.
The transactions are BY DESIGN to subsume the block reward and will handily make mining worth the price of admission.
So what's the sentiment around using GPG/PGP for email ?
While touted as replacements for traditional dead tree varieties, ebook book owners should have the same rights to lend and transfer on a 1:1 basis as they see fit.
Perhaps look at how the BitCoin "public transaction" model works to manage the lending (DRM) ??
Either it was not the case in the mid 80's or my parents couldn't co-sign.
I don't want to be "that old guy" -- but I didn't qualify for student loans in the 80's & early 90's because my parents were in that bracket where they were supposed to be able to contribute, but just couldn't.
I had up to three part-time jobs while doing my undergrad, and I definitely wanted the education -- I found that as "consumer" I demanded more from my instructors for my hard earned cash.
In the end it made me who I am, and I subsequently went on to get both an MS in Software Engineering and an MBA recently -- both paid for with cash that I earned and saved.
Sure it took a little longer to finish the degree's and barring Alzheimer's, the lessons learned all around will be mine for life!
Apotheker has to be one of the worst appointments I've seen in 20 years.
At least Chain-saw Al Dunlap was hired for the express purpose of being a major league a-hole.
Apotheker showed a shocking poverty of understanding of the empire he was entrusted to run that it makes me seriously question the competency of the people that vetted him?
I tried changing my bank account info and when I called to ask them to reverse a pending charge on the wrong/old account I was told that I would have to close/cancel my service with them, and then restart service at a new higher rate!
So I cancelled. Completely.
Now I have to play the "contest the charge on the credit card game" even though I cancelled on the 9th the charge still showed up on the 11th.
You'd think they would be doing anything to just maintain their current customers, but evidently not.
Say hello to RedBox !
Clearly he can't be trusted -- with the exception of course of furthering his own interests...
Oh wait, it didn't.
In Minnesota an in classroom system called DISCOURSE had this in the early 90's -- should be an easy patent to knock down.
