Annotating PDF files under Linux

Annotating PDF files under linux is a tough job due to some issues related to GNU PDF.

‘Okular’ is a good option, if you always use a single machine.

Okular stores the annotations in ‘.kde/share/apps/okular/docdata/’.

If you move the pdf file to some other system then all the annotations will be lost.

One solution is to move all the data from the above mentioned folder to your new system.

But this folder contains meta data from all pdf files you opened so far.

Another problem with Okular is that even if you rename your pdf file, your annotation is gone!

One solution is to use the Okular custom archive file type ‘.okular’. But this file can be opened only using Okular.

One effective solution I found is to use some windows application with wine.

It Seems that PDF-XChange Viewer is a good option to use with wine.

Hence temporarily let me work like this, though I don’t really like to work with windows 🙂

Using Norm Symbol in $latex \LaTeX$

Filed under: Uncategorized — Sooraj K. Ambat @ 13:45

There are different methods to put norm symbol in

$latex i\hbar\frac{\partial}{\partial t}\left|\Psi(t)\right>=H\left|\Psi(t)\right>$


$latex \LaTeX&s=3$

e^{\i \pi} + 1 = 0
