DiskPart Recovering SD card

My problem:
Tried installing Raspberian into 32 GB SD card. The file system went corrupt-somehow. Could not recover the other big part in windows because windows system.
The diskmanagement system showed the 30GB space in dark, which could not be accessed by simple formatting or change of the drive letter.

So, I had to go commando.
Went to the command mode.
Windows> CMD (admin mode)
Then executed the following codes...

Now I can see the whole SD card space!

Change Printers Default Single Sided Setting #mac

 Well, there is an easy way...
http://localhost:631/
This prompted me to do
cupsctl WebInterface=yes
to the terminal... which enabled opening up the printer options... then I could set up the duplex printing.
Went to
http://localhost:631/admin/#General
Then, I had to select "Two-sided, Long-edge binding".

This enabled printing on both sides.

From Google Fusion table to Google Earth Engine!

First I made a Google Fusion table with few points with Latitue and Logitude geo-coded Names.
Then imported into fusion table

// import the fusion table
var Da = ee.FeatureCollection('ft:18RyzwhfBU0TVFa4HWFEp778Tkd9YV-X1pE_Q1hq6').geometry();

// Set center of map
Map.centerObject(Da, 6);

// show the layer
Map.addLayer(Da);
The cryptic code in the FeatureCollection is the ID of the fusion table.

See an example here
