GIMP start a new path or selection

Start a new path when creating lines in GIMP.
How to create lines in GIMP?
Select the pencil tool from the toolbox, make sure the foreground color is not the same with the background color or else the line will be invisible.
If you need to specify a brush select the "brush" that you want to use to create the line.
Press and hold the "shift key" then select or click the start point.
Click the second point (while still holding the shift key) and a line will be drawn. Release the "shift key".
If you want to draw again a new line, press "shift key" but you will notice that the line will be connected to the last point that the line was drawn.
This will happen if you didn't "double click" on the last point that the line was drawn.
Even if you press "esc" key it will still continue from the old point or the new line is still connected to the end of the line that was previously drawn. Or if you’re doing a selection the new area…

Android R cannot be resolved to a variable

What works for me to solve this issue is to edit Android Manifest XML and the project properties.

In Android Manifest set the target version to the latest version:

        android:targetSdkVersion="23" />

In Project Properties set also the latest version:

# Project target.

This will work if the Android project has successfully run before but due to the latest version update of Android Studio software, the "Android R cannot be resolve to a variable" error is shown. Google wants you to set your project compatible to the newest Android version.

Cheers..Hope it helps.. :)

Android R not generated

Ever encountered why Android R is not generated?
One quick solution is to delete the “gen” folder hoping, that it will be generated again since the folder is auto generated. But it works sometimes.. 
But if Android will not auto generate the R and problem will be not washed away.
And after deletion the problem still exists, and even after cleaning the project.
So now what?
If the XML in the "res" folder, such as the "layout" XML and "drawables" XML (drawable-hdpi, drawable-xhdpi etc..) if the XML has errors on any of these folders, it will cause R not to be generated.
If the XML are all okay and still R is not generated. 
Then open the drawables folder, if any of the PNG or any images its filenames has to be in lower case and filenames should only contain lower case letters and numbers.
So images on the drawable folders which has Upper Case letters will cause the R not to be generated.
File names of images on the drawable folder which has symbols will also cause …

How to open a text file in Excel?

Excel can read and open text files.

Excel, Word or any text editing software can read, open any text file.

When opening the file on Excel, formatting will be an issue.

If text file values or data need to arrange by columns or by rows, then it could be daunting to import the file to Excel.

But if the text file is properly formatted, like values are separated by tab, comma or other symbols to segregate values or basically any delimiter characters Excel will open the text file as CSV or comma separated values without any issue.

If the text file exported from a program that has delimiters or any text file separated by delimiters then importing process to Excel will be easier.

Values will be separated based on the delimiters detected on the file.

If the file delimiter is a "tab" character or tab-delimited text file, values or data will be separated based on "tab" spacing.

"tab" refers to the actual tab, which correspond to number of spaces.
