I have a Chinese pulse oximeter. It's completely worthless as a pulse oximeter although it has a very nice OLED display. I can hold my breath for a minute and get tunnel vision without it showing any drop in my blood O2 concentration. I know this is crap because I've shared a hospital room overnight with a guy with really bad sleep apnea who was setting off his O2 alarm every 30 minutes as he entered a deep sleep phase, stopped breathing for 20 seconds, and his O2 dropped to 80%. That was a long night.

Volkswagen Factory Worker Killed By a Robot 342

m.alessandrini writes: A worker at a Volkswagen factory in Germany has died, after a robot grabbed him and crushed him against a metal plate. This is perhaps the first severe accident of this kind in a western factory, and is sparking debate about who is responsible for the accident, the man who was servicing the robot beyond its protection cage, or the robot's hardware/software developers who didn't put enough safety checks. Will this distinction be more and more important in the future, when robots will be more widespread?

US Bombs ISIS Command Center After Terrorist Posts Selfie Online 286

HughPickens.com writes: Brian Everstine writes at Air Force Times that U.S. intelligence officers were able to locate and bomb an Islamic State command center based on a photo and comments in social media. "The [airmen are] combing through social media and they see some moron standing at this command," said Gen. Hawk Carlisle, commander of Air Combat Command. "And in some social media, open forum, bragging about command and control capabilities for Da'esh, ISIL, And these guys go 'ah, we got an in.' So they do some work, long story short, about 22 hours later through that very building, three JDAMS take that entire building out. Through social media. It was a post on social media. Bombs on target in 22 hours."

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.

Comment Some appliances run fine on DC (Score 1) 597

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.

Video IT Consultant Talks About 'Negotiating for Nerds' (Video) 61

Matt Heusser did a Slashdot video interview back in 2013 titled How to Become an IT Expert Companies Seek Out and Pay Well. Despite noise from a few yammerheads about Matt getting 'free advertising' on Slashdot, which is unlikely since the vast majority of Slashdot users are more likely to compete with him than to hire him, most of the people who saw that video (or read the transcript) knew he was giving helpful advice to peers who might want to get out of the cubicle and work for themselves.

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.

Comment I lived in a FEMA trailer and it wasn't that bad (Score 3, Informative) 79

I had the priviledge of living in a government surplus FEMA trailer on a Navy base for about four weeks. It really wasn't that bad. They're just cheap trailers built by some cheap trailer company like the millions of other cheap trailers that people live in all over the US. There's nothing FEMA-ey about them. I don't know what everybody is complaining about. Bunch of whine-ass cry-babies. "Oh the FREE trailer I got from the government ISN'T GOOD ENOUGH". Or maybe this whole thing was concocted by the media. When FEMA got rid of them, this base got about a dozen, for free, and they've been lived in ever since, including by me, and they are perfectly livable.

There are those in oceanography who would tell you that Bob's submersibles are pressurized by his own overinflated ego. But I guess haters gonna hate. FWIW my grandpa met him once and speaks highly of him, and he answered a letter one of my cousin's wrote to him. And the JASON system is fucking rad.
