Package pdftex.def Error: File `xyz-eps-converted-to.pdf’ not found: using draft setting. [Ubuntu]

 in Latex  tagged eps / epstopdf / Latex / pdflatex / ubuntu by

Recently we were struggling with the following error whenever we were trying to use an eps figure with the pdflatex compiler.

Package pdftex.def Error: File `xyz-eps-converted-to.pdf' not found: using draft setting.

After trying several online remedies which all failed, we tried to convert the eps figure to pdf manually on the shell and we got the following error:

$ epstopdf
Command 'epstopdf' not found, but can be installed with:
sudo apt install texlive-font-utils

Following the advice on the shell, we installed texlive-font-utils and guess what? After compiling our Latex document again, the error was gone and the eps figure was successfully converted to a pdf!!

Set Up OpenVPN Connect with .ovpn profile for Apple iOS (iPhone, iPad) 5

 in Applications  tagged apple / ios / openvpn / OpenVPN Connect / ovpn / profile by

Search and install OpenVPN Connect from the App Store,
or download and install it from here:
https://apps.apple.com/us/app/open-vpn-connect/id590379981

After the OpenVPN Connect is installed, open the application and proceed to accept the data license agreement and configure your settings for the notifications.

In the past you could import a profile that was available on your device (e.g. if you had the .ovpn file in the Downloads folder) through the Files application.

Unfortunately, this is no more. If you press and hold the .ovpn configuration file and click on Share, you will not get the option Copy to OpenVPN…

It appears that you either need to do this through iTunes or an email that arrives to the Mail application! If the email arrives to another mail client it will not work..

The configuration profile will now be opened in OpenVPN Connect.
Click on Add.

And the click on Add again:

Click on Allow so that the OpenVPN Connect application will be able to create the necessary VPN configurations.

After this step, the profile should be operational and working properly.

Latex/Beamer: Notes page would not use whole space when in 16:9 aspect ratio

 in Latex  tagged 16:9 / 169 / aspect ratio / aspectratio / beamer / Latex by

In a recent presentation we did, we added a lot of long notes…
At the specific document we had changed the aspect ratio to 16:9 using the following documentclass.

%[aspectratio=169] changes aspect ratio for slides from 4:3 to 16:9, should be better with columns
\documentclass[aspectratio=169]{beamer}

When we compiled the presentation showing the notes on the second screen, we noticed that the notes were not utilizing all of the white space. There was a huge empty column to the right, most probably it was the space that was added after changing the aspect ratio from 4:3 to 16:9.

The template we were using for the notes page was plain. To fix this issue we used the following commands to create a new version for the plain template, called wideplain.

\makeatletter
\defbeamertemplate{note page}{wideplain}{
	\vskip.25em
	\nointerlineskip
	\begin{minipage}{.9\paperwidth}
		\insertnote
	\end{minipage}
}
\makeatother

After we used this new template, the notes became wider and they used all of the available space.

%Enable to produce notes
\usepackage{pgfpages}
\setbeameroption{show notes on second screen=right}
\setbeamertemplate{note page}[wideplain]

Note:

In the code we defined the new template, initially we used \textwidth instead of \paperwidth which resulted in the same result as the plain template. So we assume that there is an issue somewhere that the notes template does not adapt its \textwidth properly when changing the paper aspect ratio.

Latex/Beamer: Do you type too many notes?

 in Latex  tagged beamer / Latex / notes / template by

We most certainly do!

For that reason we needed to make the template for the notes as simple as possible. To avoid developing our own template for the notes page, we used one of the three basic predefined templates named plain.

Using plain we got an empty slide in the notes page which allowed us to add a lot more content!

The basic 3 template options for the notes slide are the following

  1. default The default template shows the last slide in the upper right corner and some information that should help you match a note page to the slide that is currently shown (e.g. title of section and subsection).
  2. compress The option produces an output that is similar to the default, it fits more content onto each note page at the price of legibility.
  3. plain An empty page to add notes to.

Usage example:

\documentclass{beamer}
\usepackage{pgfpages}
\setbeameroption{show notes on second screen=right}
\setbeamertemplate{note page}[default]
\begin{document}
\begin{frame}
Some content.
\note{Some note for the content}
\end{frame}
\end{document}
