Comment Re:EVs -- so SHITTY, they're now MANDATORY in CA. (Score 1) 385

I couldn't agree more. I get frustrated at the lag time from flipping the switch to the time it takes the built-in power converters in every light to turn on, plus the dimming issues you describe are a constant nuisance. Not to mention that the most common failures in modern LED bulbs are the cheap, on-board voltage converters, not the LEDs.

This is just one of the reasons I'm developing a high-quality, high-power, PoE-based LED driver that will drive LEDs using PWM instead of current/voltage-based dimming. It will have a fully open HTTP API and accept HTTP on/off and dim requests from our own PoE light switch or from any product that supports HTTP requests (like flic -- https://ancillary-proxy.atarimworker.io?url=https%3A%2F%2Fflic.io%2F ) and will operate standalone with no internet connection or cloud dependency. It will power lighting fixtures of any voltage (up to 48V) and can drive up to maximum PoE (70-90W) through a single channel or divided between up to 8 channels. And we're looking at adding DMX/ArtNet control soon. Currently, in the final stages of prototyping. Watch for PoE Lighting on Crowd Supply in about ~3 months or so.

In any case, an alternative solution that you can do today is to look at 0-10V dimming where the dimming wires are separate from the power wires and use a power supply that supports PWM dimming in conjunction with low-voltage bulbs or light strips. I'm not affiliated with any of the products or companies below, these are just examples of what I'm referring to.

Did you bother to even Google his statement? I'm sure it's not applicable to every windmill, but he does seem to be factually correct about this:

"Ironically, many industrial-scale wind turbines require an electric 'kick-start' to begin turning. That’s what overcomes the inertia of getting the blades to start turning." -- https://ancillary-proxy.atarimworker.io?url=https%3A%2F%2Fscience.unctv.org%2Fcont...

Comment Re:Lack of jobs is forcing one person from their h (Score 0) 184

Every Republican president, except GW, represented in the Senate article performed better than Obama, and furthermore, Clinton's presidency was during a overwhelmingly Republican-controlled congress. Nor does this take into account how much the national debt has grown under each president to achieve the purported "economic growth." Finally, the tiny sample size makes this a wholly inadequate statistical methodology for drawing conclusions.

I agree that an economic growth pattern started under Obama and has continued through Trump's presidency, but to deny that his policies have continued to facilitate that growth, particularly in the area of reduced unemployment, seems willfully myopic.

No insults, slinking, deflecting or ignoring needed.

CAFE is the government mandating vechicle mileage and seems to have worked.

Well, I guess that would depend on how you define "worked." The net result of this legislation is that MANY more people die every year.

"...according to a 1999 USA Today analysis of crash data since 1975, [this] roughly figures to be 7,700 deaths for every mile per gallon gained in fuel economy standards."

Comment Increased Exposure...? (Score 1) 356

I have to wonder if it would be a more accurate link between the amount of time a child spent in near proximity to vinyl flooring and not just whether or not the household had it.

In other words, if children who spend more time sitting in their homes, crawling the floor, etc, are more prone to Autism than children who spend a greater percentage of their time outdoors.

Additionally, I wonder if a similar correlation exists if there is extensive parental exposure to phthalates prior to conception.

The problem with this is simple: the author of a Wikipedia article controls your opinions about a topic by selectively choosing his sources. He can make what he writes seem extraordinarily accurate based on the sources he chooses — or more significantly, the sources he ignores.

Education

For CS Majors, How Important Is the "Where?" 991

An anonymous reader writes "I'm a high school senior who is trying to pick a college to attend. I've been accepted by two comparably selective schools. One is a highly regarded tech school, and the other is a highly regarded liberal arts institution. I prefer the liberal arts college, but the computer science program is small, graduating about a dozen students a year. The course load is heavily theory based; programming languages are taught in later years. How much would the tech school vs. non tech school matter? Are CS majors from non-tech school considered inferior? What would an HR department think? What would you think if you were hiring?"
Security

Submission + - Testing commercial 2-factor authentication systems

Fry-kun writes: I recently became interested in setting up a 2-factor authentication system for my laptop. With that in mind, I bought a fairly inexpensive USB key. Although it seems to work, I can't bring myself to trust it completely: Kensington claims that the system is secure, but there is no independent security lab analysis of the product. In other words, for all I know, there may be a gaping hole in their security setup.
Worse yet, there are apparently no reviews of the product, no mention of anyone trying to test it and no hardware hackers tried to make it work in Linux, even though it's been out for over 2 years.

How would you go about making sure that a security product does what it claims to?
