Carlisle was careful to not go into great detail about the how the information was gathered and what additional effort went into targeting those bombs. It's easy to imagine that in addition to the information gleaned from the initial post that the Air Force used satellite and drone reconnaissance data. It's also possible that U.S. intelligence could have actively engaged with the original poster in order to draw out information. Attackers and researchers have shown time and time again that simply asking a target for information—either by posing as a trusted individual or using carefully created phishing attacks—works even better than fancy information-stealing digital attacks.
Many appliances run just fine on 120v DC power. Of course it's hard to tell which ones without either taking it apart and examining it or trying it and risking the magic smoke coming out.
Nothing high-current will ever switch to low voltage DC, I hope. I'm already annoyed at my 120v electric lawn mower; stupid extension cord is way heavier than my in-laws 240v electric lawn mower in Europe. Considering the cost of copper we should be switching to higher voltages, not lower.
Seems like the batteries could be redesigned to be higher voltage to reduce inverter losses. Just add more cells.
True sine wave IGBT converters are pretty efficient.
Today, Matt is with us again. This video is about 'Negotiating for Nerds.' Matt talks about negotiating a pay raise or consulting fee increase, starting with learning who has the actual power to negotiate with you. This is essential knowledge if you are employed (or self-employed) in IT and want to make sure you're getting all you are worth.
