    If I were the owner I'd fire them regardless ... How does firing her make up for the money loss, or the potentially dangerous system in place?

    A couple of points

    Systems are difficult to test in all contingencies. There is always a major rush to install because even extra days spent on features could result in millions of reduced productivity. Hence, users have to bear a lot of risk for a lot of possible reward.

    If the higher-ups are fired, their replacements are prone to acquire a system that has fundamental flaws in other areas. They can't just turn around on the spot and install replacement software.

    A chain is a strong as its weakest link. A company that can't afford to lose $251,000,000 should put the money into separate accounts.

    There may be legal ways to nullify a contract - don't know Taiwanese law.

    Another saying: if you play with fire, you're liable to get burnt. There's always a chance something will go wrong in spite of precautions because there is so much complexity. We just have to learn from mistakes and "not let history repeat itself."

    Several people have noted that people coming straight from school just don't know what it's like to work in the profession studied for. That smacks of a serious gap in education.

    Schools can't cover every workplace situation but they may be not addressing core teaching on how to work. Surely it is less costly to inform students uniformly in a classroom rather than let them go haphazardly into whatever they can get into and then have them absorb at the whim of their bosses. Even the erratic behavior of business should be addressed in classroom theory.

    People looking for work are typically asked about their experience, usually to screen out people who don't know basics about working in the profession. The basics are so basic though. I've written software for many different businesses - there are so many little things that would have just easily been acquired in class, but university seems to have the attitude that they can just present idealized problems without the counterpart of practical processes that have a direct influence on many people (responsibility), rules, business goals, business psychology, mistakes, getting things to work, etc.

    A university degree though is still a status of being able to be employed, earning more than minimum wage and capable of learning the nuances of business towards a fulfilling career.

    It seems so needless for graduates to have to learn something they could learn in school.

    There are many articles in business computing journals and business journals that students can read on their own to see what it can be like in the workplace.

  14. Reductio ad absurdum on New Model Solves Grandfather Paradox · · Score: 1

    Assumption: Time exists.

    Deduced: Paradoxes.

    Conclusion: Time does not exist.

    Time in the way we conceive it may be an incomplete model of reality.

    For instance, we accept that light speed is the maximum yet we think the universe is expanding faster than light. This is treated as though a central time has been running at a constant pace while space expands - but what if it is time itself that is speeding up so that everything is going to its future state earlier? Locally, clocks would run at the same rate, but they would be actually falling behind the universe's time.

    It's not implausible since clocks don't have to run at the same pace everywhere, as shown by relativity. Indeed there may even be more than one "clock" experienced by any single point - we can have a local "clock", and the universe can have a central "clock".

    Destruction is fairly easy as entropy runs its course but energy and materials can be used to create some order and in some cases restore, or at the very least, replicate past states. Thus we can conceivably build worlds that existed before. Thus a clock can make a quantum leap backwards.

    A resurrected world would find itself embedded in a place where many resources have been spent to build it though. If resources still exist, as entropy unbuilds the world, it may seek to rebuild.

    Everything we see is history. Light took time to travel to us. If we can determine our past from light that bounced off us and then off something far away and came back, or was bent around a black hole and came back, we could construct a past situation and interact with it. Though the inhabitants of the situation would be told what year they are supposed to be in, they would be in two different times.

    So if we look to our past would we see history as told or an artificial constructive process?

    Well well well. It seems that there really is some intuition in the idea that mathematics cannot be purchased per unit like fruit in a grocery store.

    Paying for mathematic research is definitely liable to result in quality mathematical ideas, but intuition about the intangibles:

    A. We may hit a barrier that no real gain in mathematics can be obtained regardless of how much money is humanly available.

    For instance, suppose computers become intelligent and perform mathematic discovery very quickly. In the limit all resources that can be spent on mathematics will be - a sort of barrier.

    At any rate, the automatic discovery of mathematics is a kind of algorithm for mathematics, less than an ability to prove everything true with finite resources, but capable of proving everything that can be paid for along a finite set of thought lines.

    There is the problem of being forced to choose and thus consume resources, on the assumption that even a quantum computer cannot consider all choices. But who knows? It may be possible for a computer to handle all elements of infinite sets, maybe even uncountable sets!! Mathematics and physical reality may have far more in common than what we can tell.

    B. Mathematics per dollar - a genius might see a solution quickly while an organization spends billions going nowhere. Did Fermat really know a proof but the NSA could have (and may have) dumped untold money while Wiles put the pieces together all by himself.

    C. The result belongs to the mathematician first. Perhaps the proof becomes obvious but if it isn't a mathematician funded by the NSA could foresee a wonderful conclusion and find a more lucrative buyer.

    Ultimately the human race can purchase mathematics but the NSA is a tiny bit more limited.

    Very well. The shower is even better for a water source. Start it on a drip and run that into a funnel. Because it is so high, no siphoning is required.

    Further design ideas with flowing water. Use an IV bag full of cold water and let it slowly drip on your body, in the case a fan or electricity is not available. It must be questionable how much heat a fan can generate but they seem pretty efficient.

    Sometimes I wonder how well water cooling really works when water just flows in a stream. If you blow hot room air into a cold shower will the bathroom get any colder? I suppose it's moot because the humidity will be a killer. Some air conditioners use cold water but they have numerous fins on the pipes in order to get massive surface area in contact with the air.

    I wonder how much a car radiator costs - maybe no more than $50 just for a new one. Will it will rust while plain water goes through?

    Patient people can fold a mega long copper tube into quite a space-filling array or use a large number of straight and T pieces to make such a contraption, which will have a large surface area.

    A fan running on low is much more quiet and less energy consuming than an air conditioner. It's just a matter of whether comfort can be achieved at the sub $50 mark. Water based air conditioners can easily pump out 25000 BTU - there was one in a restaurant and it chilled the dining room quite fast. Get enough surface area on the pipes and you can make your living room pretty cold. Compressor-based refrigerators can go below the freezing point of water though. My food thermometer in the cold water tap never showed any temperature below 10 C although it reads 0 C for ice and 100 C for boiling water.

    So if water might be put into a low-pressure chamber or bottle that allows water vapor to escape the room, the bottle could be used as a source of powerful cooling. Just not sure how to keep outside air from entering the bottle.

    Not only this, if the freezer is in the same room as his "air conditioner" he is actually warming the room up by freezing the ice

    I've seen a few perpetual motion rebuttals. But let me remind you of a couple of facts.

    A. The cold water tap is a source of cold. The idea is to convert this source into cold air.

    B. A freezer need not be in the same room. It could even be in the hot garage.

    C. The room can be quite small so it won't take a lot of water to get a noticeable cooling. I tried the same thing once in a largish room and it didn't work because there was too much air. The air around the water cooled ok, and the water warmed up quickly but there was no comfort.

    D. Air conditioners can be purchased for $100 or less. An extra $80 isn't a big deal in a first world country.

    Still, the apparatus is useful in a situation where an air conditioner can't be easily mounted - these things are cubic and heavy, although surprisingly liftable once you are on your knees and your body is underneath. They really should have handles and perhaps telescopic legs.

    If anyone is mounting an air conditioner into a wall/window, it can be lifted into place by this procedure: Get a large number of phone books from the phone company. They're free. Put machine on a board supported by a couple of phone books. Start low to the ground, as low as you can lift to. Add phone books to the left and right side to raise the unit without tipping it much until it is level with the place you are going to put it into. Now lift the machine up and in.

    Common sense: if you are lifting to a high place you may need phone books in 4 corners and a wider board. Of course a project of this magnitude typically becomes tackled by a team whereas a water air cooler belongs in the realm of the individual, in which case everyone can just lift the machine into the opening.

    I can say all of this after I lifted my air conditioner - from the side - along an aisle wide enough for just the machine into a hole in the wall. It was possible with one strategic knee motion and care not to impart acceleration in unfortunate directions. Just aim the centre of mass towards the opening and let inertia take over. Prior to this, adjust the body to be able to permit such motion without being dragged the wrong way by the machine. To avoid difficulties, practice swinging the machine a couple of degrees back and forth to know you can make the move while remaining stable. I wonder how much a car engine crane costs.
