  1. Re:Weather, not climate on New Record High Temperature At South Pole · · Score: 2, Informative

    You have to move the air, which causes noise.

    False. Well, just about anything causes some noise, but it does not need to be noticeable. Think for a second. Recording studios and TV stations need air conditoining, and have strict limits onthe amount of noise that is tolerable.

    You can easily convert energy into heat, another form of energy. But you can't convert it into cold, which is the lack of energy.

    False. "Converting" energy into cold is the purpose of air conditioning

    ou have to generate heat to generate cold -- in fact, more heat than you generate cold, due to entropy.

    False. Study up on thermodynamics a little. The COP of A/C is usually well over 1.0.

    Add to this that heat radiates, while cold doesn't.

    False. Well, at least in the same sense that the standard direction of flow of electricity is from positive to negative. Radiant heat flow causes the cold side to get warmer and the warm side to get colder. Radiant cooling systems have been in use for a long time, though they're hard to manage in humid climates due to the need to avoid condensation

    If you're used to 10 dB ambient sound levels when no one is talking, a "silent" central air unit of 30-35 dB sounds rather loud. I know, because I sit in an office with central air right now. Those who are conditioned to the sound won't hear it, but central air is far from silent.

    Just because many central air systems are noisy, doesn't mean they have to be. Also, most heating systems include fans and coils/heat exchangers, so can be just as noisy. 10dB or 30 dB by themselves mean nothing, by the way, as dB are relative units, and you haven't indicated the base, nor have you stated whether you are talking sound pressure or sound power. Assuming 10 NC or RC, you're complaining about something that is too quiet to notice in almost all normal environments.

    People here can't hear a mosquito from across the room or their watch ticking on their arm, because it's never silent.

    Often true.

    In large parts due to air conditioning, including central air.

    Seldom true, especially least in the winter.

    Prices don't go down when demand increases, prices go down when you have more product than buyers.

    Prices go down in a competitive environment when improved technology allows cheaper manufacturing or improved efficiencies. Those sorts of improvements are what the subsidies were supposed to jump-start.

    Get the government and unions out of education, and watch achievement return to what it was in the '50s and '60s.

    First, government was just as involved, if not more so, in education in the 50s and 60s as it is now, and unions were prominent in education during that time (at least in Chicago, of which I'm most familiar with in the 60s)
    Second, if you were aware of reporting about education in the popular press in the 50s and 60s, and even the 30s and 40s, you would be aware there have always been alarming stories about how bad public education is and how it's going downhill.

    Use of electricity during the day = $0.05/kWh. Use of electricity an night = $0.50/kWh. Now you've got to solve the battery problem AND the solar panel problem.

    Nah, then all you need is batteries and a charging and inverter system. No solar panels at all. Because all you'd have to do is store electricity from the company during the day, and use it at night or when the power is down. Right now, there's no great price advantage to doing this, but the second the day and night prices diverge significantly, there would be.

    Hhmmm, it seems those sorts of rates are already in use.

  9. Re:Welcom to Shitty Wok on The Undeclared "Cyber Cold War" With China · · Score: 1

    Citation needed. "Race" is obviously a simplification, but to deny there's no genetic difference between someone from China, someone from Africa, an aborigine from Australia, and someone from Germany is not only wrong but ridiculous. Furthermore, people from those different groups of people absolutely have recognizable genetic trends: i.e., two people from Germany will be much more similar genetically than a person from Germany and a person from China.

    There are real differences among various populations spread around the world.
    But they don't rise to meet the biological definition of race.

    The biological context of the term race is only widely accepted when used to refer to a subspecies arising from a partially isolated reproductive population and thus share a considerable degree of genetic similarity.

  13. Re:Faulty Reasoning on Does Outsourcing Programming Really Save Money? · · Score: 1

    I don't understand why managers would go for a cheap hourly rate, when the total cost of the final product should be the measure of costs.
    If you're "outsourcing", shouldn't you be defining the results needed and asking for al fee to accomplish it?

    I work for consulting engineers, and typically the only times hourly rates come into play are when client changes come after work is completed. Everything else tends to be flat fee for a more-or-less defined project scope. That still leaves room for someone to fuck the job up, but it allows you to require them to fix it for free (or if they don't, to withhold payments)

  14. Re:Full text of the bill on US Senator Proposes Bill To Eliminate Overtime For IT Workers · · Score: 1

    Mod parent up, Informative.

    This seems to be a tempest in a teapot.
    If you're being paid by salary, you're almost certainly already exempt, and this change won't affect you.
    If you're being paid an hourly rate less than $27.63 an hour, this change won't affect you.
    If you're being paid an hourly rate greater than $27.63 an hour, you're probably already be exempt, but with this bill your company won't have to go to court to find out for sure.
    Also, if you're being paid an hourly rate greater than $27.63 an hour, you should be compensated at your hourly rate for overtime, there just won't be a question in law of whether you should be compensated at 1.5 times your hourly rate.

    This bill tries to clarify things so there are fewer lawsuits
    (We'll see if it actually works.)

    Frankly, I've worked as an engineer (mechanical, not software) being paid hourly rates for 30 years, and I've never gotten time-and-a-half for overtime, even when I was just a draftsman making $7 / hour. But I've always been paid my regular hourly rate for overtime, unless I chose to take compensatory time off, instead.

    This is about INTERNAL mail. Don't know many companies who are opening lawsuits against themself. Not using email does not mean it will not be documented somehow.

    For outside lawsuits, internal e-mails may still be evidence.

    Regardless of that, internal e-mails still help document that you sent someone that file, that your boss directed you take some particular action, that you have a due date, etc. In my experience, not using e-mails severely reduces the chance that things will be documented as required, unless you're still using snail mail or faxes.

    You are drinking the koolaid. Social Security by itself is completely solvent for the next 15 years, and the long term shortfall could be easily addressed by raising the cap on payments into it to a higher income level or cutting the benefits about 15% to 20%.
    The real problem is not SS, but the fact that Congress borrows the SS surplus and counts it against the deficit.
