Title: IT/Dev[op]s Army Knives Tools for the researcher: a journey from SSH to Git

Download the slides (PDF)

Abstract

This seminar will review some of the most sensible tools every researcher (in computer science but not only) will probably have to use through his daily work. In particular, the objective is this talk is to make the attendees [more] confortable with the following tools:

  • SSH (Secure Shell), which permits to establish secure tunneled connections to remote servers, thus serving as a generic secure medium for all kind of useful operations (access to remote servers, online backup, SOCKS proxy, transparent by-pass of multi-layer firewalls etc.)
  • Git, one of the best and most efficient Version Control System (VCS) available today;
  • Vagrant, a virtualization framework facilitating the generation of development environments

In addition, several other tools / approaches will be reviewed since they proved to be very useful in a research context. For instance, PGP / GPG will be covered since it offers a scalable mean for exchanging encrypted / digitally signed information (through mails, files and/or git). If you use ruby or python for your research prototypes, you might be interested to know how to create sandboxed and reproducible running environments across developers. Finally, you probably spend a lot of time taking notes, writing documentations, articles or producing [LaTeX/Beamer-based] slides. At this level, you will want to know about Markdown, an easy text syntax that can greatly enhance and accelerate these operations in a way that will be detailed.

Outline / Technical Recommendations

All attendee are strongly encouraged to bring their computer laptop since the talk will integrate a set of hands-on / exercises that will have to be performed individually.

Registration

It is preferable but not necessary to register in advance (by sending an email at catherine.violet@uni.lu). Note that you will have to sign the attendance sheet on site
