Thanks for coming!

300+ Attendees. 2 Classes. 1 Night. See it in photos.

3157 Hackathon. October 9th. Roone Auditorium.

Homework, made fun.

The 3157 Hackathon is an optional hackathon intended for students and alumni of the w3157. Students from w3136 will be there, too!

Food? ✓ Swag? ✓

As well as awesome people, we'll also have snacks and drinks to keep you fueled all night, 3157 swag, and swag from our sponsors!

No experience necessary.

This hackathon isn't just for homework, it's also an open learning environment. Whether you're a hackathon veteran or first-timer, stop by.


Hackathon! On Friday October 9th, from 7:30pm to 2am, students will be working on two big assignments: lab3 and lab4. Alumni and TAs will be around to help, too.

​There is no demo, there is no judging, and there is no prize. Just all night hacking, good food, lots of laughter, friendship, and feeling good about helping others and asking for help. No showing off and no embarrassment. We are very proud of the fact that Columbia CS students' first hackathon experience is that of cooperation and friendship, not of competition.


OK, but who's coming?

Current Students

Show up to get work done on your labs, to get help, or to help your classmates.

Former students

Come and help out current students (while also hacking on your own projects!)


Hang out, eat free food, talk, listen, learn, laugh, and sleep.

I have questions.

  • Do I have to go?

    Attendance is not required. It's completely optional. It's totally understandable if you have better things to do Friday night than geeking out all night.

  • Do I have to stay all night?

    If you come, you don't have to stay all night. You can come and go as you please

  • What should I bring?

    In addition to a good atitude, please bring a (ideally charged) laptop, your charger, and CUID.

  • Can I work with others?

    During the hackathon, we will have a very loose collaboration policy. You can look at your classmates' code to learn or to help. You can sit down with someone else and try things together. All we ask is for you to make a genuine effort to learn or to help. You should list the poeple you have collaborated with in your README.

  • I want to collaborate. How?

    Additionally, if you wish to set up a Github repo for yourself and your partner, the repo must be private. GitHub offers free private repository (and a bunch of other goodies!) to students, but it takes a week or two to process, so make sure to sign up before the hackathon.

  • Got anything else for me?

    The hackathon would also be a great opportunity for you to learn from your savvy TAs and classmates about some of the extra stuff that will enrich your shell experience—nifty .bashrc setups, vim/emacs setup, VirtualBox setups, using GDB, etc.

Ok, I'm in.

Glad to hear it. RSVP here, then we'll see you in October!

This isn't your first rodeo, is it?

Not even close. in Spring 2015, we packed over 230(!) current and former 3157 students in John Jay. So many, we've outgrown the space. You can see more photos of the Spring 2015 hackathon here.

In Fall 2014 we had over 200 current and former 3157 students hacking in John Jay.

In Spring 2014 we had over 160 current and former 3157 students hacking in John Jay.

In Fall 2013 we had over 100 current and former 3157 students hacking in Carleton Lounge.
