How to open folders with multiple tabs / view directories with multiple tabs on Windows

Two solutions:
1. Download clover. It hijacks your default folder viewer to allow for multiple tabs. This software used to cause trouble but it's improving. If you are concerned with uncertain risks this is not for you.

2. Use Google Chrome! For example, open a new tab on Google chrome and type C:\\
You will open your C disk folder on Google chrome and view its contents. The advantage is you can combine your multi-tabbed browser with multiple directories into one single window.

How to print/extract/save powerpoint notes to a text file on Mac

It's a little bit tricky. I'll take Mac Office ppt as an example

The principle is ppt -> pdf -> txt

1. open your ppt file
2. on the top bar click File -> print
3. in the printer window, make sure you select PDF as the output instead of real printers
    current option -> "PowerPoint" Layout -> "Notes"
    Click print
    You'll get a pdf with both the slides and texts
    But the slides are in image format so the texts in the slides won't be recognized and saved, so that you can only save your notes

4. go to http://pdftotext.com/
5. drop your pdf file to the upload box
6. click "Download All"

Alternatively
4. open the pdf using acrobat adobe
5. File -> Save as -> more options -> Text

The easiest way is: manually delete your group chat history and some chat history with a lot of videos/photos.

That works very well.

linux: can't grep/join txt file due to weird parsing

It's probably due to special windows characters hidden in your txt file created on Windows

One way to tell is:

wc $(head -1 yourtxtfile)

to see from the error message whether your first line contains anything like '$'\r'

If yes, you can remove them on Linux by using:
awk '{ sub("\r$", "");print $1}'  yourtxtfile
