iPad connects to weak WiFi network
I found one very interesting fact... my work place has a very weak public WiFi. My iPad normally doesn't able to see and connect to it. But once I connect a Bluetooth device (either my MacBook Air or even just a bluetooth keyboard), I am able to connect to this WiFi network.

How to Use Exposure Compensation to Take Control of Your Exposure
http://digital-photography-school.com/how-to-use-exposure-compensation-to-take-control-of-your-exposure/
- Aperture Priority Mode – In Aperture Priority mode, exposure compensation changes the shutter speed. Remember that in this mode, you set the aperture and the camera sets a corresponding shutter speed. If you change the Aperture, your camera just sets another corresponding shutter speed, and there is no change in the exposure level. Exposure compensation gives you the ability to change the shutter speed (and the overall exposure value) while staying at the same aperture you originally set.
- Shutter Priority – In Shutter Priority mode, exposure compensation changes the size of your aperture. It is basically the reverse of Aperture Priority mode. You set a shutter speed, and the camera sets a corresponding aperture. Exposure compensation therefore changes the exposure by allowing you to change that aperture size.

Tips for using Oracle (for beginner)
Useful SQL statements
get all the tables
SELECT * FROM TAB ORDER BY TNAMEget all the columns
select * from col where tname = '<table name>' ORDER BY colno
Return Top n records (Select Top 1 * in MS SQL)
SELECT column_name(s)FROM table_name
WHERE ROWNUM <= number;
Concatenation Operator
- ||
IF THEN ELSE ELSIF END IF example
IF (...) THEN...;
ELSIF (...) THEN
...;
ELSE
...;
END IF;
GetDate() (in MS SQL)
- sysdate
Table DUAL
A dummy table with a single record used for selecting when you're not actually interested in the data, but instead want the results of some system function in a select statement:- select sysdate from dual;
Sequence
Opento see the defination (Last number too)
Get next value
<sequence_name>.NEXTVAL;
INSERT INTO <table>
(<col1>, <col2>)
VALUES
(<seq_name>.NEXTVAL, 'xxx');
you can't use CURRVAL until you have used NEXTVAL at least once in your session.
Data Types

Photography - Close up
Don't cut off body parts except at the mid chest, waist or mid thigh region.
http://www.izzyvideo.com/close-up-shot/
http://www.izzyvideo.com/close-up-shot/
- medium close up (MCU) - cut at waist, show hands movement, with head room above the head
- close up (CU) - at the chest, with head room
- head and shoulder close up
- head close up (big head close up)
- choker close up - the face only
- extreme close up - the mouth only
Sunny 16 rule
If it's a sunny day, set aperture to f/16 and shutter speed closest to the reciprocal of yout ISO.
Use f/16 for sunny settings, but go down for less bright conditions:
- ISO 50, 1/60 sec
- ISO 100, 1/125 sec
- ISO 200, 1/250 sec, etc.
Use f/16 for sunny settings, but go down for less bright conditions:
- f/11 for cloudy daylight
- f/8 for overcast
- f/5.6 for outdoor shade
- f/4 for dark shade

Dos and Don’ts for Shooting the Moon
Do use a tripod
Don’t use a slow shutter speed
The moon is actually moving very quickly around the earth at a speed of 2,288 miles per hour (3,683 kilometers per hour). Because of the moon’s speed and the long focal length necessary to capture an image of the moon, you need to use the fastest shutter speed possible. A good rule of thumb for tack sharp moon photos is nothing slower than 1/125th of a second.Do use a telephoto lens
To successfully shoot any kind of detail of the moon in your image, you need at least a 300mm telephoto. For a full frame image, you will need around an 800mm lens.Don’t use any filters on your lens
Do try the Looney 11 rule
The Looney 11 rule is similar to the Sunny 16 rule. Set your f-stop to f/11, then match the shutter speed to your ISO.- With ISO 100, set the shutter speed to 1/100 or 1/125 second
- With ISO 200, set the shutter speed to 1/200 or 1/250
- With ISO 400, set the shutter speed to 1/400 or 1/500, etc.
Don’t touch the camera to start your exposure
Using a cable release or remote trigger is the best way to start your exposure. If you don’t have either of these gadgets, use the self-timer feature on your camera to begin your shot.Do use Mirror Lock-up
If your camera gives you the option to lock up your mirror this can greatly increase your chances of getting a tack sharp image.Don’t use Image Stabilization
Canon’s IS (Image Stabilization) or Nikon’s VR (Vibration Reduction) must be turned off anytime your camera is on a tripod.Do know the cycles of the moon
The Photographer’s Ephemeris will not only give you the phases of the moon, but also show you when and where the moon will appear in the sky. By far the most photographed stage is the full moon, which is also the brightest and the most difficult to expose correctly. The side lighting of the Gibbous stage produces some interesting shadows which may allow you to capture craters and mountains. The crescent moon is, of course, the darkest stage, but one which may create some interesting effects when added to a nighttime landscape.
Don’t always place the moon in the center
Don’t just put the moon in the center of your image with nothing else – it’s been done a million times before and there is nothing exciting about this. Try to include other objects in the frame with the moon.
Don’t just place the moon in an empty sky. Including a foreground object will create a more dramatic image.
Do switch to manual focus
Don’t just shoot the moon at night
The best time for photographing the moon is just after it rises or just before it sets, when it is very low in the sky. When the moon is near the horizon, it is closest to Earth and will appear larger in your images. Also, as the full moon rises the sun will be setting, and as the full moon sets the sun will be rising. This may give you great lighting to include or accentuate foreground or landscape objects. Shooting the moon in the day time will give you opportunity to include foreground objects, and you also may be able to capture some craters on the moon’s surface.The June full moon, called the “Honey Moon”, captured as it sets at sunrise.
Do use exposure bracketing
After you are satisfied with the exposure you have dialed in, bracket two stops under and two stops over, just to ensure that you get an exposure you will be happy with later.Don’t use Auto White Balance
Using auto white balance will give you very inconsistent results. What is the source for the light of the moon? That’s right, the sun! So try daylight white balance, but if you are looking for a different effect, try tungsten or cloudy.Don’t depend on your meter
Most likely your camera’s light meter will be fooled by the amount of light reflecting off the moon. Also it is important to note that as the moon rises, the exposure will continual change. It gets brighter as it rises, so you need to keep adjusting your shutter speed.
