Chart Title - Superscripts & Subscripts

I'm sure many of us stuck with this problem where we want to put some superscripts or subscripts character in the chart title or axes.

One way of workaround is by using unicode character. You can insert either "Insert -> Symbol" for MS Office Excel or "Insert -> Special Character".

From wiki, all you need to do is insert the desired "Character code" for example "00B2" for superscript 2.

Good luck!!!

Qiqqa

Probably Mendeley and EndNote are the most popular reference manager so far. I don't think many people ever heard of qiqqa.

qiqqa is an awesome reference manager [RM]. The most important features of this RM are:
Integration with MS Word for ref. citation.

• Easy to find missing reference with BibTeX Sniffer
• Related articles recommendation
• Tagging
• Annotation
• Annotation report
• and many more

Here, I want to share an easy way to cite reference in your paper.

• Press "Add citation" button. You can do this on a single pdf or multiple pdf. This button will insert citation-cluster (unformatted reference style) and merely indicate that there will be a citation there.
• Add "My Bibliography Section" text at the reference section in your paper. This will alert qiqqa to insert bibliography here later.
• Press "Add bibliography" button
• Select your preferred CSL style (in my case: IEEE)
• Click the magic wand "Reformat all citations"
• DONE!!!

More on qiqqa functions and features can be found on  qiqqa manual.

Compare PDFs

Sometimes, we have different versions of pdf files which at some point lead to confusion.

No instruction is needed to use this software. It pretty straight forward.

Other than methods described above, linux user can also try method explained here.

LaTeX Series: XeLaTeX

Knowledge of the day:

You can use XeLaTeX to use system fonts instead of limited to fonts provided by TeX.

Try it yourself using the following codes, and compile with XeLaTeX

\documentclass[11pt]{article}
\usepackage[english]{babel}
\usepackage{blindtext}
\usepackage{fontspec}
\setmainfont{Arial Narrow}
\begin{document}
\blindtext
\end{document}

Happy "XeLaTeX"ing

Manjaro Series: Dropbox

You can install dropbox from AUR as detailed in ArchWiki

yaourt -S dropbox

As for my installation, dropbox popup for syncing didn't appear at all. So, I need to do some simple tweaking [via dropbox]. Run the following codes one by one:

cd ~ && wget -O - "https://www.dropbox.com/download?plat=lnx.x86_64" | tar xzf -

~/.dropbox-dist/dropboxd 

You should be prompted with dropbox welcoming screen and from here, you need to log in and select the desired Dropbox destination folder.

Upon completion, your Dropbox should be syncing and you can safely quit.

Now, you can restart your dropboxd from Internet->Dropbox

Finally we can remove unused our manual installation dropbox folder and tarball downloaded:

rm -rf ~/.dropbox-dist dropbox-lnx.86_64-2.6.7.tar.gz

You can enjoy your Dropbox happily ever after ~hopefully.
