What is TuPL

TuPL is the programming languages research group at Tufts University. Here, we do research that innovates the way to think about programming. More specifically, we do research in domain-specific programming languages (DSLs), program synthesis, language-based security, type systems, program verification, and more. For example the RedLine Systems research group, a subgroup of TuPL, primarily does research into automatic memory management. We are also interested in programming languages education: check out Norman's foundational programming languages educational material, which will be in the press soon!

If you are interested in doing research with us, please check out (and apply to) the PhD program in computer science at Tufts University.

For people who will practice the profession of software, programming-language skills are growing steadily more important. Twenty years ago most software practitioners got everything they needed from studying C or C++, maybe supplemented with a little Awk or Perl. Today's practitioners will use a much wider variety of programming languages, not just over the course of their careers, but even in their first jobs. Budding practitioners need a book that gives them something to do, so that they can develop skills. For a number of years I have been working on a book that aims to meet this need.

Join Us - new member orientation

What follows is a guide for new TuPL members to follow upon arrival to Tufts. This is written by grad students, and primarily for grad students. If you're not a new graduate student much of this information may still be pertinent to you, but you should get in touch with your primary TuPL contact to figure out which pieces are pertinent.

Linux home directory

Once you arrive on campus the first thing you should do is head to the EECS systems staff in Halligan Hall room 231, located at the far end of the hall visible while standing in the second floor kitchen. They are available Monday through Friday, 8am to 5:30pm and will help you get setup with a username and password for the EECS network of linux servers, lab computers, and your home directory.

If you ever forget your EECS password but know your Tufts email / UTLN password, you can recover access to your EECS account by going here: https://www.eecs.tufts.edu/~accounts/reset.cgi.

GitHub

Once you have an EECS account, you can use that to login to https://github.cs.tufts.edu. You must login to GitHub first before we can add you to the Siriusly github organization. To do so, contact our Internal GitHub organizer and request to be added to the Siriusly github organization.

Once you have been granted access to Siriusly on GitHub, please go to https://github.cs.tufts.edu/Siriusly/tupl-website and make a pull request with your contact information added to the bottom of the Current Graduate Students HTML-div of this document. The same applies for new undergraduate students working on a project with any current TuPL member.

If Sam Guyer is your advisor, you will want to ask him to have you added to the Redline Research organization on public github.

CSLOL

Although not specific to TuPL, the Computer Science League of Learning (CSLOL) is the de facto graduate student organization for computer science graduate students at Tufts. To learn more about access to housing in the Medford/Somerville area, which classes to take, and all other non-research related issues please contact a CSLOL executive or member. This can be done by setting up a CSLOL Slack account here with your Tufts email address, by contacting any of the current TuPL graduate students to figure out who the current CSLOL President is, or by contacting @TuftsCSLOL on facebook. As of this writing the website https://sites.tufts.edu/cslol/ is very out of date, but contacting the @TuftsCSLOL admins on facebook is the most likely way to get a response if you have trouble signing up for the CSLOL Slack.
