  1. Re:There's still the pollution thing on The Box That Built the Modern World · · Score: 5, Insightful

    Correct. People don't realize how fuel EFFICIENT shipping really is. At "Slow" speeds (18 knots) where more than 1/2 the worlds cargo ships run, and figuring a 9000-10000 TEU ship (aka holds 9000-10000 20 ft containers, 1/2 that if all 40Ft boxes) - the ship will typically burn 100 Tons of fuel/day - or 1/100th of a ton of fuel per container/day, and roughly (because bunker C - the 'crap they burn' - Now there are roughly depending on exact fuel 250-280 gallons/ton of fuel - so it takes about 1/4 gallon of fuel per DAY to move each one of those containers. But the joke? Go to the online shipping calculators - China to west coast USA (where it will get put on a train) - 15 days, NOT 15. So you are talking roughly 3.75 gallons of fuel to move that container of tee-shirts from China to the US - that's the container, all the goods etc.
    Work the math. You probably burn more fuel per shirt driving to the store, picking up the shirt, and driving home than shipping it from China takes. Remember - ships float, and take surprisingly little fuel per ton to move freight. It is why canals were such a big deal back when - a full barge of coal or gravel or whatever could be moved by ONE horse.

  4. Re:Bacteria spread via the air on Legionnaires' Bacteria Reemerges In Previously Disinfected Cooling Towers · · Score: 1

    We were insane. Every machine room was swept daily, floors stripped and waxed 1x/week (in the machine room!!), readings and wipe down of the machines was done 4x/day, so you could see if there were any leaks etc. Spares were labels and neatly hung. Each machine room had a spare TOWER and spare compressor in line - just open valves, and turn on. Building also ran at 100% fresh air, all electrostatically precipitated. Yes, the building was a virtual clean room. Did I say we were a BIT crazy?

  5. Re:Bacteria spread via the air on Legionnaires' Bacteria Reemerges In Previously Disinfected Cooling Towers · · Score: 1

    I spent a summer working for a place that had oh, 15-20 towers. TWICE a week we dosed the tower with biocides and rust preventatives, and once every 2 weeks samples from each of the towers went out for analysis. Then again, I know from my father, who worked in the field, the place I was at was 'odd' in that we did way more PM than any other place he knew of (he was in the repair end, I was doing operating). Sounds like the places with the problem aren't putting in the money. The problem with tower water is it tends to be warm, and it is recirculated with lots of air blown over it. Algae buildup is a HUGE problem and I'd bet that the places in question have that problem too, and don't think about the efficiency problem the algae cause...

  7. Re:Honestly? on Windows 10, From a Linux User's Perspective · · Score: 3, Interesting

    One major advantage over 7 (although 8.1 had it - but who wanted 8.1)
    Multiple magnification settings

    Win7 allowed ONE windows magnification setting for all screens (100%, 125%, 150%). Win10 allows you to set it per screen. Useful if you have one High DPI screen (my laptop) and one standard DPI - the second monitor in my case.

    Other than that? No huge difference. Some things are faster (just as they were in 8.x). The first machine I upgraded was on 8.x, and couldn't wait to get rid of that pig. Then I upgraded the laptop that has the high DPI screen, but right now, my main boxes are still on Win7...

    I can tell you live in a city (Apartments etc)
    Why?
    When you live in the less dense parts of cities/burbs etc, you car DOES drop you at your door already, it is called a garage or a driveway. It stops, it is there when you walk out the door with no calls, no "There is no car available right now, you will have to wait 20 minutes" (which means you will always have to plan to leave early - trust me, used to use a car service). Yes, when you go into "the city" it will be easier to park but

    Other things people hate about public transport:
    There are a LOT of people who DON'T live in a city, they live in suburbs, ex-urbs or gasp, the country. Public transport is often 1/hr in the suburbs, and at that, may come as "close" as a mile or two to where you live. Live out in the country, where you next neighbor is a mile down the road (or further) the whole car sharing thing becomes a joke
