Comment Re:50% is lost in AC to DC conversion? (Score 1) 466

Typical 12Vdc smart battery chargers used in the marine and RV industry are more than 80% efficient - the Magnum Energy MS2812 inverter/charger I have installed on my sailboat is 85% efficient when charging the batteries (converting 120Vac to 13.8Vdc) and 88% efficient when inverting (taking 12Vdc nominal and converting it to 120Vac).

Unfortunately, Congress is ceding power to both the Executive and Legislative that can only weaken our rights and liberty. They are becoming less and less relevant.

Uh, unless things have changed around here, Congress IS the Legislative branch of the US Federal government.

Ah, the old Zeroth Law of Robotics: A robot may not harm humanity, or, by inaction, allow humanity to come to harm.

So the AI won't melt its positronic brain when it deduces that by eliminating sufficient #'s of humans, it actually saves humanity! They're here to save us from ourselves by killing us. Brilliant!

All hail our positronic savior AI overlords!

I thought you guys believed in the immortal soul of man. You know, an eternity burning in Hell if you didn't accept Jesus Christ as your personal Lord and Saviour? Or an eternity in Heaven eating grapes and playing the lyre if you did?

Perhaps deep down you're really a Hindu like your pseudonym "reboot", and you're continually reborn to try one more lifetime to get it right? Will this life be the one?

The US mortgage industry single-handedly is keeping facsimile alive and well. Anyone who's bought a house lately can attest that they have no clue about PII in unencrypted e-mails, and think nothing of asking you to print out, sign and initial a 60 page document, then fax it back to them. And then they have the gall to complain when you reduce their 8.5 x 14 legal size documents to 8.5 x 11 because your $99 inkjet printer/scanner can't handle legal size.

With throwback companies like that, you'd never know that the mortgage industry is the major backer behind DocuSign. Another reason why banks should issue you a digital certificate when you open an account. If the US Government can implement PKI for their own use, surely the more nimble private marketplace can do the same... /s

Current hysteria sounds like assassins can use the pump to kill their targets and avoid discovery, which unless answers are "yes" and "yes" is false, or at least no worse than current medical devices.

Maybe the pump is crap, but the security researcher here is more crap, and /. peanut gallery is worst crap.

That is in fact what the researcher is saying - the answers are yes and yes. By simply gaining access to any configured PCA pump, whether it's in hospital inventory, on any patient (including an attacker admitted as a patient), an attacker can remotely manipulate any identical PCA pump on the "secure" wireless network. And as others have said, since these pumps generally dispense opioid pain killers, it would be trivial to kill most any patient attached to one.

What you're advocating is security by obscurity. Since this flaw is no longer obscure, the pump is no longer secure. Oh God, I'm channeling Johnny Cochran during the OJ trial.

Where have you been? This is exactly what's underlying ISP opposition to Title II. It's not because they don't want regulation. It's because, like Nazi Minister of Propaganda Joseph Goebbels, they want to control the message. One can do that if they control the production and the delivery of information.

Comment Re: I'm ready....My ISP isn't. (Score 1) 390

I'd venture a guess that AT&T Uverse either hasn't IPv6-enabled their CDN, or they haven't executed any contracts with their CDN suppliers which demand IPv6 support. IOW - Stuttering videos aren't caused by IPv6, it's probably because AT&T may not yet allow Netflix or Google/Youtube to install 6-enabled caching servers in AT&T's network. I wonder how their own video streaming sources work over IPv6? I can't test that theory because right now my ISP is Verizon FIOS...

Comment Re:Why is it even a discussion? (Score 1) 441

Not quite true. The first cellular service in the US was launched by just prior to the January 1, 1984 divestiture of the Regional Bell Operating Companies (RBOCs - the local service providers of telephone service) from AT&T - the long distance provider. The March 6, 1983 launch was by the future RBOC which would become Ameritech. So while technically not AT&T, it was the spawn of AT&T.

And one certainly didn't get cellular service back then because you were tired of being overcharged by AT&T. A normal cellular bill back then was way over $200/month - in 1986 dollars. And that got you maybe 60-70 minutes of air time, and didn't include long distance either.

Back in the day the FCC, through spectrum allocations, mandated that each major future cellular (they weren't called wireless back then) market would be divided into two: the non-incumbent "A" service provider (e.g., like a Cellular One in the NYC metro area) and the incumbent "B" service provider (like NYNEX in this case). So in lots of markets wireless startups were funded by investors who'd make a killing. But in other markets, the non-incumbent carrier was simply another RBOC which was entering into a new territory.

So when we get to kernel version 4.1.15, it will speak with an Austrian accent rather than Finnish?

And of course, when we see the later T-1000 form a pointy sword from its liquid metal arm and kill young John Connor's foster father, it's further proof that there's still old cruft code in the future kernel, since it's just reproducing Linus' most famous gesture.
