# A mysterious error of Verbatim environment in fancyverb package.

I’ve got the following error with Verbatim environment.

! FancyVerb Error:Extraneous input ^^I\end{}’ between \end{Verbatim} and line end.\FV@Error …ncyVerb Error:^^J\space \space #1^^J} \end{Verbatim}^^I

For example,

\documentclass{article}\usepackage{fancyvrb}\begin{document}\begin{Verbatim}int sum=0;for(int i=0;i<size;i++){   sum += i;}\end{Verbatim} \end{document}

I could not find any syntax error in the above code.

It turns out that the error is caused by an extra whitespace after \end{Verbatim} command. I mean literally a single whitespace after the “}” bracket of \end{Verbatim} command. Who in the heaven is going to notice that?

After I remove the whitespace and recompile the latex document, the error disappears.

# Set a timer for automatically shutting Windows PC down.

We can set a simple automatic shutdown for a Windows PC by creating the following two plain-text files.

• PC_scheduled_shutdown.bat
@echo offtitle Shutdown Inputset /p mins=Enter number of minutes to wait until shutdown:set /a mins=%mins%*60shutdown.exe -s -t %mins%
• PC_abort_shutdown.bat
shutdown.exe -a`

Put the above two files on your Desktop folder.

Then, when we want to shutdown PC in the next t minutes such as 30 minutes:

• Double-click “PC_scheduled_shutdown.bat
• Enter 30 in the pop-up command prompt window. That’s all.

If we want to cancel our scheduled shutdown before the time is up, double-click another file, “PC_abort_shutdown.bat”.
