today's EE's dont' even know how to solder. its pathetic. they run a sim and type on keyboards. some don't even use test gear, like scopes.

I think that's more of a "todays college graduates" issue than anything specific to EEs. I'm a computer science major and I can solder, use a dmm/osciliscope/spectrum analyzer, program PICs and microcontrollers, design (simple) PCB layouts, design (simple) circuits, etc. I'm even working on a summer project to build a theremin using surface mount parts. This is all in addition to the standard CS skillset, and I do it because my immediate reaction to coming into contact with something I don't know or don't understand is to try and learn all that I can about it.

But then I've got classmates who don't know any of that stuff, and also constantly struggle with even simple CS concepts. They don't want to learn new things, they just expect that now because they did the bare minimum of effort to obtain a degree they'll land a 100k a year job doing "coding". Even though they still have only the vaguest idea about what coding actually is or how to do it. I know someone who's theoretically starting on their junior year, yet struggles with things such as implementing a function in a java program (and the entire early CS curriculum is basically in java, so it's not like a language issue or something). The scary bit is that a lot of these people have already graduated.

Submission + - Getting the most out of the space station (before it's too late)! (nature.com)

bmahersciwriter writes: NASA administrators are strategizing a push to do more science on the International Space Station in the coming years. The pressure is on, given the rapidly cooling relations between the US and Russia whose deputy prime minister recently suggested that US astronauts use a trampoline if they want to get into orbit.
Aiding in the push for more research is the development of two-way cargo ships by SpaceX, which should allow for return of research materials (formerly a hurdle to doing useful experiments). NASA soon aims to send new earth-monitoring equipment to the station and expanded rodent facilities. And geneLAB will send a range of model organisms like fruit flies and nematodes into space for months at a time.

If you can't have your data available to demonstrate what you're doing it lawful, and you are going to delete it, then only reasonable conclusion is what you are doing cannot be proven lawful.

Therefore, the program is not lawful, and you need to stop.

So if you're not going to answer the questions to demonstrate your innocence, and your memory is fuzzy anyway, then the only reasonable conclusion is that you're guilty and therefore need to be thrown in jail?

That's a bit of a dangerous precident to be setting.

Submission + - West Antarctic Ice Sheet, is being melted by geothermal heat from below (phys.org)

bricko writes: Thwaites Glacier, the large, rapidly changing outlet of the West Antarctic Ice Sheet, is not only being eroded by the ocean, it's being melted from below by geothermal heat, researchers at the Institute for Geophysics at The University of Texas at Austin (UTIG) report in the current edition of the Proceedings of the National Academy of Sciences.

The findings significantly change the understanding of conditions beneath the West Antarctic Ice Sheet where accurate information has previously been unobtainable.

The Thwaites Glacier has been the focus of considerable attention in recent weeks as other groups of researchers found the glacier is on the way to collapse, but more data and computer modeling are needed to determine when the collapse will begin in earnest and at what rate the sea level will increase as it proceeds. The new observations by UTIG will greatly inform these ice sheet modeling efforts.

Even then... It's been my experience that assuming you're not an idiot (granted that's a bold assumption since you didn't study until the night before) and showed up to lectures or at least know a little about the material, you'll often have better chances reasoning out the questions in a less sleep deprived state.

Especially if you were that much smarter than humanity. It makes about as much sense as humans deciding to wipe out canine life on the planet. In fact dogs are a hell of a lot better off because humans are around. Instead we control them in ways dogs don't understand.

I'm out of mod points, but that's a actually pretty insightful.

I'd suspect that the first AIs we'd see (if sci-fi style AIs even become a thing, I don't think they will but that's a different argument) would be to do things like predict markets and aid in complex decision making. If AIs did decide to "take over", I would suspect that it would come in the form of giving humans advice, and then humans willingly following that advice because they know that the AI is quite smart and it'll make things work out well in the long run.

Eventually humans might technologically regress (or AIs might just become smart to the point we can't comprehend their thought processes anymore) that the AIs become the future analog of old time prophets telling people when to plant their crops. I doubt that an AI would decide to kill all the humans, thought they might end up using humans as pawns to kill each other. Either for population reduction or maybe to take out or defend against a competing AI or some reason completely incomprehensible to us. By that point humans may willingly go and do it in the same way that dogs have been used for similar tasks.

The problem is that there's only so much you can do to a signal to amplify it before there's no signal left.

With a current gen headset, if you were to turn off the 60hz notch filter, the signal it would be picking up from the power lines would drown out the brain signals by several orders of magnitude. Even someone waving their hand over top of your head while you wear one will cause enough interference to blot out the sorts of signals the brain produces. On top of that, those signals that we can pick up are extremely broad, created by millions of neurons firing in sequence. Unless it becomes legal to plant wires in peoples heads that can detect the actions of single neurons, or we develop some kind of wearable FMRI, the kind of things that article is worried about are so far ahead as to be in the territory of asking how we should regulate flying cars.

EEG technology is akin to telling what state a computer is on by opening up the case and pointing some IR thermometers at different components and measuring the temperature. I could tell if you're doing something graphically intensive vs CPU intensive vs memory intensive, and maybe make some inferences based on the time of day and previous states but that's it. It doesn't matter how much more sensitive you make an IR thermometer, it's not going to give me any more detailed information than a vague idea of what bits are being used more than others.

Or is it a click-bait headline that really means here's a couple of companies who have a product which does it but nobody else does?

Definitely a click-bait headline. They have enough trouble getting the accuracy and resolution required to tell those sorts of things with medical grade EEGs, let alone a consumer grade headset.

Submission + - Lithium-Ion Batteries Be Woven From Yarn In The Future?

cartechboy writes: Currently, battery packs are solid units that take up space and are available in limited shapes. But what if your entire car seat became a large, comfortable battery? If recent experiments by scientists at Fudan University in Shanghai, China become reality, future lithium-ion battery packs could be woven from a yarn-like fabric. Wei Weng and his colleagues have designed and fabricated carbon nanotube composite yarns that can be wound around lithium-ion battery fibers and onto a cotton fiber, to create a lithium-ion battery. These fibers with a 1mm diameter can be woven into flexible textiles or cloth, like strands of any other material. This could lead to the dawn of wearable electronics since devices would have a power source that wouldn't require pockets and compartments for solid batteries. This leads to the automotive application for electric cars. Where there's material, there's a potential battery--think automotive trim panels, seats, carpets, and more as potential batteries. The battery so far exhibits impressive electrochemical properties--0.75 mWh/cm energy density and capacity retention of 87 percent after 100 cycles. Improvements are on going, but this could be the next big thing.
