Comment Re:Wedding, parade, club DJs will pay the bill (Score 1) 349

The organization that collects fees for songwriters (sorry, I can't remember the evil organization's name) from bars who hire cover bands and use jukeboxes refused to pay their extortion fees, and the cost of defennding his rights in court bankrupted him. His bar is no longer in business.

That evil organization was probably either ASCAP or BMI.

FETs are different from plain NPN or PNP transistors, yes.

So what? The same argument applies. PNP, NPN and MOSFET transistors are ALL analog devices that can be employed as digital switches or analog amplifiers, just as tubes once were used in both capacities. My point is that your "tubes are analog amplifiers while transistors are high speed switches" ignores that both function in similar ways, that transistors and tubes are both analog devices that can be employed as digital switches. One important point of the article was that the new tube-like devices can actually switch *faster* than existing transistors, making them superior components in certain digital switching applications. This is a turnaround from the historic transition from tubes to transistors due to improvements in power efficiency, switching speed and size reduction leading to integrated circuit chips and modern computing.

Tubes are analog amplifiers, transistors are ultra high speed switches that need additional components to become amplifiers.

You were doing fine until you got to that last sentence. Actually, a transistor, as used in a typical amplifier circuit, is just as much an analog amplifier as a vacuum tube. A MOSFET transistor works in a very similar way to a typical amplifier vacuum tube like a 6V6 except that as a semiconductor device it doesn't require the high working voltages and glowing filament of a vacuum tube. Both tubes and transistors require additional components to function...power supplies, output transformers, feedback circuits, noise filters, etc.

You laugh, but I would *love* to have an AM radio in my MP3 player. So far I have not found any..... now maybe with microtubes, it will be possible.

That's what the fillings in your teeth are for, dude...listening to AM radio and the voices of the aliens telling you what to do.

Focusing on CO2 levels, instead of radiation from nuclear power plant failures, use of depleted uranium for warfare, deadly chemicals in our air, soil, & water, and genetic franken-foods aren't the bigger threats is really, really short-sighted & misdirected.

Or perhaps arbitrarily choosing one of the above to avoid researching is really short-sighted and misdirected.

Comment There Are Multiple Problems At Work Here (Score 1) 463

Having worked in a couple of newsrooms I have some experience with this phenomenon. To wit:

o Reporters come out of college with a BA in journalism, communications, or literature and usually have little to no background in the physical sciences.
o Assignment editors running the news desk tend to have a rather low opinion of their viewers, based on viewership ratings and their own prejudices.
o Most newsroom managers handle the "big picture" decisions and leave the copy writing to the reporters and editors.
o Most copy editors, research staff and proofreaders simply check the facts within the story and the grammar, leaving the content to the writer.

The majority of writers are either predisposed to dumb down their reporting due to their lack of expertise in the subject or the pressures of 1) lack of time for researching, and/or 2) column space and time limitations describing the subject. Over time they also are conditioned to self-edit their works by their assignment editors or others who review their work and edit out the "technical parts" for brevity and to keep the readers/listeners/viewers from "tuning out."

So far i've been totally unimpressed with LED lights. They just don't seem to last even as long as an old incandescent bulb at all. While costing a ton more money. Light color looks pretty good. But lifetime is really horrible. Near as i can figure i'm losing money as well on the bulb cost vs. the electricity used.

Maybe this one will be different... But not at $60 a pop. Or even $22. Get it down to $8 and we'll talk. And i might even put up with them burning out way too quick sometimes.

What brand and model of LED lights did you use? As many others have noted there is a vast difference in quality and performance depending on the make and model. It's useful for others if you can note which ones perform well and which aren't up to snuff.

I have 9 LED lights in my home. One is a FEIT brand PAR38-style light I use in a fixture above my bathroom shower and the other 8 are Ecosmart PAR30 lights (sold at Home Depot, made by LightingScience) in my office/music room. So far I'm quite pleased with the results. All are working fine with great brightness and color rendition.

I'm especially happy with the Ecosmart ECS 30 V2 WW FL lights: 950 lumens output, 3,000K color temperature, CRI rating of 83, slightly under the rated 17 watts power consumption (confirmed with my Kill A Watt unit). That's a net efficiency of 56 lumens/watt. Plus they are very nicely dimmable even with a cheap X10 lamp module. I can get a pleasant and very usable background lighting by dimming the bulbs until they draw only 5 watts each. No flicker, great color, low power consumption...and very little waste heat.

In fact, I would enjoy seeing a corporation take a case like this to the Supreme Court and say, "I am legally a person and so the blah blah blah law shouldn't apply to me because it is a violation of my Nth amendment rights as a person.

Great...another opportunity for the Supreme Court to FURTHER expand on the insanity of the Santa Clara County v. Southern Pacific Railroad decision. Like my mom says: "We need that like a hole in the head."

"Hey, our budget could very well get cut soon. Let's fine people for things!" That's what I suspect the FCC's reasoning is. They just wont admit it.

That makes no sense. $25k is nothing to either Google OR the FCC and wouldn't impress any legislator responsible for approving FCC budgets. The fines probably go into some general government pool that wouldn't affect their resources.

What makes more sense is the FCC did this to give other corporations the message that they need to come clean about what they've done and not drag their feet providing subpoenaed information.

how can you impede something that you are innocent of ?

Isn't that the equivalent of saying - "I did not do it" and continuing to protest such ?

No, because the delay was separate from their declaration of innocence. They impeded the government's investigation by not providing the court subpoenaed information relevant to the investigation in a timely manner. When investigations go on longer than necessary it increases the workload for the investigators and their assistants and results in increased the costs to the taxpayer.
