上个月7月11日换了oncor 的smart meter,换表之前6/30-7/11总共用了300度电/11天,换表
之后从7/11-8/1用了2900度电/20天。家里在上个月并没有生活习惯上的变化,电怎么会差别

发现的物体,并不是一个正方形,甚至不是一个规则的形状,那么如何在描述一个物体

I have given this picture to both my 7 year old and 9 year old to solve the
problem.
Here is the solution so far by 7 year old.
Use the volume of a cone: 1/3 Pi (r^2) h
His guess is r is 2.5 meter, h is 1.5 meter
So total volume is 9.81 cubic meter
Using density of 1.4 ton/cubic meter, total weight is 13.74 ton
So 30222 lb.
9 year old solution so far:
Using google earth sat img from noon (using software scan howard county)
She found this pile of dirt most likely match this address.

Rotor Power Meter/Garmin 810
Tue, 02/05/2013 - 10:17pm by Andy Shen
Chad Butts just got Rotor’s new Power Meter Cranks so I stopped by his
studio while Mark Purdy installed it. Here’s a quick first look at this new
power meter.
The Rotor retails for $2350, which puts it between the other two major crank
based power meters, SRM and Quarq. Its major feature is that it’s
essentially two power meters, with 4 strain gauges on each crank ... 阅读全帖

Yesterday I couldn't sleep, maybe due to insomnia.
but I kept thinking how to improve the efficiency for fishing in
such a big lake in winter.
One idea I got is described as followed,
Before water becomes frozen, we can put two cables into the bottom across
the lake.
the two cables are 100 meters away, which will let us use a net with 100
meter
wide.
when fishing begins, we first break the ice in the two endings of the lake.
We have two open water areas, one in one side of lake, another in the

5. Put More Variety in Your Speedwork
Many runners do no speedwork at all. Those who do often fall into a rut,
running the same workout time after time. Pierce learned long ago that this
approach makes speedwork much harder than it should be. "I used to run the
same speed workout week after week," he recalls. "After a while, I would
start to dread that workout. Speedwork is much easier when you change it
around a lot." The FIRST runners do many different speed workouts at... 阅读全帖

I think TTL flash is a great feature but it takes a lot of practice to
really understand it, and set correct FEC before even fire the flash.
There are two flash metering mode, Evaluative vs Average. you can google
what it really means, but it seems
1. when use flash as main light, use evaluative metering
2. when use flash as fill light, use average metering
If you are controlling multiple flash on a trigger and cannot set metering
mode separately, use evaluative mode.
Now for FEC, my rule of th... 阅读全帖

来自主题: PhotoForum版 - 搞混了一个最基本的问题
you just need to try and see what works for you. people who use manual
setting only look at meter for reference. what ever meter to use, doesn't
matter. If back light from a window, I can use evaluative mode, meter off a
carpet near a person on the floor, and set exposure. Why, b/c I did not
trust that spot meter when facing light. I can include some bright light and
part carpet on the floor and set exposure. Just need to get to know your
meter.

Basic spot meter operation
(1) set your camera on manual metering mode, set to spot metering
(2) select your desired aperture
(3) put the imaging circle on your subject’s skin then take your reading.
If using your camera’s meter, adjust your shutter speed until your meter
is at the center zero point.
这个第三步没看懂,我都是点测光表之后,AE lock, 然后就拍了,为什么还用adjust
shutter speed ?

II. The Vostok Ice-Core
To demonstrate the methods used in dating ice-cores I will use the Vostok
ice-core as an example because I found plenty of literature on it and
because it is an Antarctic ice-core which was what the original post was
about.
How It Was Collected
The Vostok Ice-Core was collected in East Antarctica by the Russian
Antarctic expedition. The Vostok Ice-Core is 2,083 meters lo... 阅读全帖
