Skype Data rates

Hi all,

according to https://support.skype.com/en-us/faq/FA1417/How-much-bandwidth-does-Skype-need

(1024kByte = 1MByte); (8kbps = 1kBps)

calling

--------

minimum:

30kbps = 30/8 kiloBytes (per second) = 225kiloBytes (per minute) = 0.22 MegaBytes per minute

if they charge both upload and download, then it would be 0.44 MegaBytes per minute

recommended:

100kbps = 100/8 kiloBytes (per second) = 750kiloBytes (per minute) = 0.73 MegaBytes per minute

if they charge both upload and download, then it would be 1.46 MegaBytes per minute

 

 

video calling
---------------

minimum:

128kbps = 128/8 kiloBytes (per second) = 960kiloBytes (per minute) = 0.9375 MegaBytes per minute

if they charge both upload and download, then it would be 1.875 MegaBytes per minute

recommended:

300kbps = 300/8 kiloBytes (per second) = 2250kiloBytes (per minute) = 2.2 MegaBytes per minute

if they charge both upload and download, then it would be 4.4 MBytes per minute

• so if you assume minimum requirements and charge for only download it will be
• calling->0.22MB per minute
• video calling->0.9375MB per minute

cheers!

To highlight or edit a pdf file with pdf/a standard

Hi guys,

• Sometimes you come across pdf files that are protected by the author. PDF/A is such a standard, which makes the document even not possible to higlight.
• If you want to convert such a document to a normal pdf follow these steps.
1. Get hold of a pdf creator: I use PrimoPDF; it is free (http://www.primopdf.com/)
2. Open you protected pdf: you can use the free adobe reader X
3. File->Print and choose the PrimoPDF as your printer
• That's it! The resulting PDF can be edited.

Cheers!

How to get rid of extra line spaces in LATEX: itemize, list, enumerate

Hi all,

Sometimes, the default line spacing in enumerate or itemize is too large.
This is how you can reduce it:

1. Create your own command and use it instead of {itemize} or {enumerate}

\documentclass[letterpaper,11pt]{report}

\newenvironment{packed_enum}{
\begin{enumerate}
  \setlength{\itemsep}{1pt}
  \setlength{\parskip}{0pt}
  \setlength{\parsep}{0pt}
}{\end{enumerate}}

\newenvironment{packed_item}{
\begin{itemize}
  \setlength{\itemsep}{1pt}
  \setlength{\parskip}{0pt}
  \setlength{\parsep}{0pt}
}{\end{itemize}}


\newenvironment{compactlist}{
 \begin{list}{{$\bullet$}}{
  \setlength{\partopsep}{5pt}
  \setlength{\parskip}{0pt}
  \setlength{\parsep}{0pt}
  \setlength{\topsep}{0pt}
  \setlength{\itemsep}{0pt}
  \setlength{\itemindent}{0pt}
  \setlength{\leftmargin}{10pt}
 }
}{
 \end{list}
}

\begin{document}

\chapter{My List}

Here is my list.

\begin{packed_enum}
   \item Item 1
   \item Item 2
   \item Item 3
\end{packed_enum}

\begin{packed_item}
   \item Item 1
   \item Item 2
   \item Item 3
\end{packed_item}

\begin{compactlist}
\item Item 1
\item Item 2
\item Item 3
\end{compactlist}

\end{document}

--------------------------
By changing the size of {pt} in
\setlength{\itemindent}{0pt}
\setlength{\leftmargin}{10pt}
you can change the indent of the bullets.

PDF go back from links of the same document

Hi guys,

• In certain pdf documents you find hyperlinks to pages in the same pdf document. However, I always wondered how to go back once you click them.
• This is how it can be done for Adobe Reader X:
• right click on the toolbar on top (just below the menu bar) and choose "Page Navigation". Select "Previous View" so that it will be displayed on the toolbar.
• The shortcut key is "ALT+left arrow" key

Hope it helps!

Cheers!
