  1. Re:Rock On, Dudes! on EU Recommends Noise Limits On MP3 Players · · Score: 2, Informative

    Personally, I wouldn't mind having an MP3 player that warn me with a "please override" message before I accidentally expose myself to unhealthy sound levels. When the ambient noise is loud, it's often very hard to notice how high you've cranked the volume.

    The iPod comes with a default sound limiter that you can arbitrarily change/set/overide at will and never be asked about again. Would something like that work for you?

  2. Re:Yes, if the opamp can drive them on EU Recommends Noise Limits On MP3 Players · · Score: 3, Informative

    I think you're off by a bit. Even cheap op-amps can output 100ma. A 10ma limit on 32 ohms would give you a max volume of only 3.2mw. Max voltage output over headphones is typically +/-1v, so max current output should be ~33ma at a minimum.

    On the flip side, there are also a lot of headphones with high impedance?

    Low impedance. Most ear buds are 32 ohms. A pair of good over-the-ear studio style headphones are 24 with some as low as 16. You still need to have a driver that can supply the current.

    The most stable, versatile and powerful operating system is useless if the users don't like the applications that are made for it. It is the applications and ease of use that make people choose an operating system, not the quality of code in the operating system.

    Then I guess it is a good thing that "the entirety of the US" is not involved as a "contributor to the body of knowledge". Only, what? 0.1% of the country is involved in research, at most?

  6. Re:Unintended consequences: in astrophysics ... on White House Plans Open Access For Research · · Score: 1

    The majority of basic research isn't done by private enterprise because there is often no immediate financial gain from it. Basic research exists to expand the body of knowledge. It often takes decades for scientists to understand the results of basic research enough to begin to figure out ways it can be used in industry or in our every day lives. Only then do the results of it become financially beneficial.

    This part of your statement is true.

    Without government funding, the US would continue to fall further behind in the sciences.

    This part of your statement is false. Private enterprise routinely provides grants and funding to Universities to perform research. Some basic, some applied. Government funding is not the sole source of funding for basic research.

    Ebay owns about 25% of Craiglist. That's what's different. Actually, Microsoft owned about 18 million shares of Apple at one point. That would be equal to 72 million shares today due to splits or about 8% of Apples outstanding stock. If Microsoft hadn't made sure it was non-voting stock, it probably would have allowed them to have a member on Apples board as well.

    I won't disagree that it was a broad uprising. However, prior to it Carter pressured the Shah to allow Ayatollah Khomeni to be allowed back into the country and a larger number of other things that essentially unblocked the Ayatollahs path to causing the uprising and taking power in the first place. I won't argue Carter is solely responsible, but it appears he does a portion of the blame.

  9. Re:Why not just USB and normal Networking? on Air Force Extends Plug-and-Play Spacecraft · · Score: 1

    USB uses 5v and a maximum power limitation of 2.5w. Also, it doesn't support direct device to device communication and requires a host (i.e., the computer) in order to operate. It's also doesn't allow real time sending of data. The physical interface is also lacking for satellites in space. That tiny connector wouldn't make it into orbit before breaking. So, you need a new electrical, communications and physical interface. AKA a new standard. There is some reusability as they are using a TCP/IP router, but they still require a an applications interface (one level higher than TCP/UDP) for the different parts to automatically recognize and talk to each other.

    Oh, and it's $200 Million, not Billion and that is for the full development of the program (testing, prototypes, etc). The development of the interface standard is at $500 Thousand.

    Wishbone is a communications interface for CPUs. The AF is looking for a standard interface for discovery, cooperation, power, communication and a host of other things and it has to be capable of sufficient redundancy in a space environment. An "Analysis of Alternatives" (seeing if there is anything already out there), is a requirement prior to any program like this going forward. In other words, they already checked.

    This craft is also capable of bombing missions, according to the Military Channel's own documentaries on experimental craft. It DOES have a bomb bay and missile mounts. The same documentary also said that this craft is capable of completely autonomous aircraft carrier landings, and can even do so in the dark. (a milestone feat in itself, due many factors)

    Are you sure you're thinking of the RQ-170 and not the X-47B? The two appear to be vastly different aircraft, even if they do look similar.

    Fun fact. You're wrong. Out of world military spending: Including the cost of Iraq and Afghanistan it's 41.5%. Excluding Iraq and Afghanistan it's closer to 35%.

    How many conflicts has the US fought in the last 50 years where the opposing military even had an air force?

    Vietnam War, Libya (multiple 80's incidents), Iran (multiple 80's incidents), Iraq (gulf war, gulf war 2). Those are the ones I know of off the top of my head. Also, aircraft have multiple uses besides pure air superiority. Reconnaissance is the main use of UAVs right now (being able to see over the next hill can be useful in avoiding ambushes). Bombing is another use, especially when you need some extra support in a fire fight.

    Except the electors in the US system are not directly elected by the people, they are appointed by state officials.

    Depends on the state. In West Virginia, the people vote for the electors directly. In other states, the members of the electoral college are chosen from pools put forth by the political parties where you select which/how many from each party pool based on the parties of the candidates. Other states are a lottery from the voting population. Not all states appoint the electoral college.
