Comment My wife takes crazy amounts of call... (Score 5, Insightful) 249

I learn to sleep through it. My wife is on call very nearly 24-7 and gets called multiple times every night.

Her phone vibrates, then does a loud alarm, sorta like a Hollywood submarine dive alarm. The vibrating phone on the nightstand usually wakes her, but not always. She reacts to her phone immediately, but not to other noises. If I need to wake her up for some reason it is easier to call her phone, then get her attention.

The key is you need to pick an alarm that you will respond to immediately, but your partner will tend to ignore. Then have the alarm become something that will wake the dead so your partner can kick you out of bed.

Comment IR end some people see into a little further too (Score 1) 350

I see slightly into the infra-red end of the spectrum, and proved it repeatedly in film photography class. When we were rolling negatives for small batch developing in full darkness I could see my classmates, and if they dropped something I could pick it up and take their hand and put the whatever in their hand.

The downside is my resolution in IR requires total darkness, and is very very faint. I didn't believe that I was doing it until I had several experiences with it and some conversations with classmates. I have met another person who also reports a similar experience, so I have to believe it is not terribly uncommon, just uncommon to recognize and not all that useful for most people. I would be unaware of this ability if I never took film photography.

Because your experiences in the UV end of the spectrum are obvious enough during full light I expect that projecting a large rainbow from a prism on a wall and having several people mark the lowest and highest portions of the spectrum will give you results you will find useful. Have them also mark individual color bands and you can calibrate the setup to other people in a repeatable manner.

Comment Color E-ink display or I don't care (Score 1) 140

My wife loves her Kindle. She uses it a whole lot, and the battery life is incredible and nearly what is advertised (30 days!). I would like one too, but I want color E-ink. I know, it only matters with maybe one of 10 documents I read. (especially considering that I reference out-of-print scans from Google books rather frequently)

Failing color E-ink, I probably will not get a Kindle.

Comment Children's toys (Score 4, Insightful) 297

I have a kid (3 yo) with toys that do stuff and/or beep. Easily 100 AA batteries in JUST her toys. (although she does not play with many anymore so they are getting packed up for donation) Funny thing is we got her a wooden train set, no batteries at all, and now almost all the fancy electronic toys are left alone! We will see if this holds true for more than a few weeks.

Amazing how much more powerful imagination is than batteries.

Comment I have a 4 acre lawn (Score 1) 514

I have 4 acres with trees, and get sick of mowing. (I also have a 1 acre woodlot) I see that the solution given is flawed for several reasons. In the real world it will produce a poor looking finish, but that is tolerable. The lawn will be one height and neat, but not well finished. Also the mowing modeled as a circular area is a built in inefficiency, because only the edge of the circle is cutting.

I did not get out of the setup whether edges were treated as "hard" or "soft". A hard edge you cannot pass the mower over, this would be a wall, tree, mailbox, or valuable planting. A soft edge would be a material that you can pas the mower over, this would be a driveway, patio, and certain planting bed edges.

I find that the best balance in real world finish and speed is when I mow 2 laps around the edges so I can turn with my old school garden tractor, then to create boxes that move across the yard. This allows for maximum velocity to be maintained, long orderly cuts which provide better finished appearance than irregular turnings, and adequate turning radius for my equipment, which is very different from the OP's.

Since my machine has a top mowing speed of about 5mph, and a 46 inch cut, this takes just under 1 hour per acre, for me. About 3 hours for 4 acres on a good day mowing neat growth. If my meadow has sat for several weeks, it will take 3 hours to mow and mulch that area alone, a common problem in the spring since it is river floodplain and will be under water a fair number of times.

With a zero turn cutting a 60 inch path at up to 9.5mph going in straight lines will outweigh minimizing recut because slowing down to turn reduces the area cut per unit time more significantly than cutting a small area a second or third time. That is a muscle car of a lawnmower the OP is using. He should take a whole lot less time to mow than he reports, probably because of all the turns he is taking.

Comment proof (Score 1) 868

The Royal Navy tested alcohol for "proof" and decided that 100 proof would be 50% alcohol by volume. This is because gunpowder saturated by 100 proof alcohol still burns vigorously enough for use in a cannon or rifle.

So navy stores would be a minimum of 100 proof spirits so if a keg of spirits was broken and wet the gunpowder the warship would still be a vessel of war. Spirits would be diluted in the fresh water to prevent the wood barrels from becoming slimy and spoiling the water.

Comment Trying to prevent a McDonald's coffee job... (Score 1) 30

This is trying to cover medical and time off work, plus a little, in an effort to prevent a repeat of the McDonald's coffee debacle. The man can prove that he was injured, and the jar contributed to his injuries. Del Monte and Kroger are just trying to prevent a PR nightmare with a relatively small (for the companies involved) sum of cash.

Comment Re:...or you could add something for yourself... (Score 1) 519

At a friend's bachelor party we got horrendous service. We then made the waiter calculate out a 20% tip, and left a $0.02 tip.

We were slightly drunk, he would not serve beverages other than alcohol (we had a designated driver), and wouldn't even ask for refills of the alcohol after the second round!

Typically I leave a 20%+ tip, with a $2 minimum per head (So when my wife, daughter and myself go for Chinese they know they are getting $6 or more, we go there often, they just bring soup before we order) The best places to eat around here are not very expensive.
