October News Update

Posted on October 17, 2019 by Overleaf Feed

September is always a busy month for us here at Overleaf, as for a lot of our users it marks the start of the new academic year, bringing with it a mixture of new and returning students, along with the researchers and teachers preparing for their new classes. So welcome back if you’ve just been on a summer break! Since the launch of Overleaf v2, we’ve continued to work hard behind the scenes to make many updates and improvements to the platform (including the newly released TeXLive 2018 image), and we appreciate everyone that’s written in to report bugs or with feature suggestions; you all help us make Overleaf better for everyone.

Benannte Referenzen in LaTeX

Posted on October 12, 2019 by Uwe Ziegenhagen Feed

Neben \ref{} und \pageref{} gibt es mit \nameref noch einen weiteren Befehl zur Referenzierung von Labels. \nameref{} gibt dabei den Titel des referenzierten Abschnitts aus. Daraus kann man dann auch einen \niceref{} Befehl bauen, der sowohl den Titel als auch die Seitenzahl in Klammern referenziert. \documentclass[12pt,ngerman]{scrartcl} \usepackage{babel} \usepackage[T1]{fontenc} \usepackage{csquotes} \usepackage{hyperref} \usepackage{fdsymbol} \newcommand{\niceref}[1]{\enquote{\nameref{sec:abschnitt}} (\(\triangleright\)~\pageref{sec:abschnitt})} \begin{document} Siehe […]

2019-10-10 Post Mortem for Outage and Incident Affecting Access Control

Posted on October 10, 2019 by Overleaf Feed

Earlier today, at 02:40 GMT, an outage at one of our infrastructure providers caused a site-wide outage at Overleaf, which lasted for approximately 40 minutes. During this time, no users were able to access their projects on Overleaf. When the provider recovered, Overleaf came back online at 03:18 GMT. However, during this restart, a component of one of our services did not restart correctly. Unfortunately, this led to an incident affecting access control, as summarized in this post mortem.

Overleaf’s Remote Hackathon

Posted on September 25, 2019 by Overleaf Feed

Hello everyone. I’m Roberta, one of the new product managers here at Overleaf, and I want to tell you how we recently organized a REMOTE hackathon! You might be thinking of broken up conversations over a dodgy connection, people not hearing properly what is going on in the ‘conference room’ etc. etc. - we’ve all been there. But thankfully none of that happened. In fact, our remote hackathon was such a blast that we are planning on making it a regular thing.

Retrospective: Modelling Overleaf with the Viable System Model

Posted on September 24, 2019 by Overleaf Feed

At Overleaf, we run regular retrospectives, bringing the team together in a video call to reflect on our progress and think of ways to improve ourselves as an organisation. We also like to experiment with the format of these retrospectives, changing the structure and topic of the meeting to shift our focus and see ourselves from new angles each time. For our last retrospective, I asked the team to zoom out and look at Overleaf as a full system, through the lens of the Viable System Model.

Aufgaben zum Bruchrechnen erstellen mit LaTeX und Python

Finding files by expansion

Posted on September 6, 2019 by Some TeX Developments Feed

The TeX core situation Loading files is an important part of using TeX. At the primitive level, reading an entire file is done using \input. As many people know, files are found by a TeX system using the kpathsea library, which means that the argument to \input should (usually) be the file name alone. However, it’s often convenient to have files found in subdirectories of a project: the LaTeX2e \graphicspath command is perhaps the classic example where this is used. Looking in multiple places means having an approach to searching for files. The same idea comes up again with graphics whenever you use \includegraphics: most of the time, you don’t give the file extension but rather let (La)TeX do some searching. At the same time as this need to search for existing files, there’s the issue of when a file might be missing. The \input primitive is pretty unforgiving if the file is not found, and there are lots of times we want to ‘use this file only’ if it actually exists, or to retain control of the error state if a file is missing. Classical TeX offers one way to check for files before trying to input them. That’s ...
