Github Dating Simulator hool pupil, finding love could be difficult. Likewise, finding individuals

As being a highschool pupil, finding love may be difficult. Likewise, finding individuals ready to invest their weekend teaming up beside me at a hackathon could be hard as well.

At hackCooper 2016, we caused Isabella Berry to resolve both of these issues with Github Dating Simulator, a credit card applicatoin that analyzes compatibility between Github users simply by using graph concept therefore the energy of love. It is maybe perhaps not a dating simulator within the old-fashioned sense—rather, it is an internet application that enables individuals trying to find hackathon groups to get people who have comparable coding backgrounds in order to avoid the trouble of scrambling to get a group in the eleventh hour.

Github Dating Simulator is available in two tastes. “Dating mode” permits a user to input two Github usernames to ascertain just how suitable they’ve been. “Team generation mode” (the greater amount of mode that is practical permits a person to enter a list of Github usernames, will get back perfect pairings for every single for the users. It enables them to create a few choices, such as for instance what amount of individuals must certanly be contained in each group.

For each and every match that Github Dating Simulator analyzes, it outputs a “compatibility” percentage, which will be basically the program’s confidence level why these two different people should be able to come together well.

Only for enjoyable, it creates a listing of “first date ideas”, that are essentially arbitrarily created task some ideas in line with the languages that are common between each individual to greatly help kickstart the ideation procedure. (when it discovers really appropriate matches, in addition outputs a summary of “first date places”—a.k.a. upcoming hackathons.)

I became accountable for the UI design together with technical execution on this task. One of the most statistically intensive jobs I’ve done to date, Github Dating Simulator depends on a mixture of the Github API and graph algorithms to effortlessly and accurately set users.

Pairing Algorithm

To generate matchings, it seems in the language use of each individual and compares it for an experience-based degree to those regarding the other users. This means somebody who features a great deal of repositories written in Ruby are going to be marked as an “expert” while Indian dating an individual who has just only written 70 lines of Ruby is going to be marked as being a “beginner”. This enables users become matched along with other programmers proportional for their level of skill, that allows programmers to work well with individuals of comparable coding backgrounds, making for the much simpler hackathon experience overall.

(that is something which ended up being extremely contested, as you might want to fit people with additional experiences with particular development languages with those individuals who have less experience for a far more academic experience. Possibly a choice for this kind of matching algorithm will be the next change.)

My records and sketches when it comes to UI design.

For a graph, each individual is plotted off their users with various paths of varying “lengths”. Each individual is a node regarding the graph, and every course represents a typical language between two users. (If two users usually do not share any languages that are common they’re not going to have paths among them.) Path length is determined by the mean square distinction of each of the languages a person understands.

The algorithm attempts to discover the path that is shortest (essentially, comparable experiences with specific languages) between two users. After that it aggregates all the paths between two users right into a single “compatibility” metric predicated on a logarithmic scale, after which starts producing matches beginning with the compatibility percentage that is highest. When a individual happens to be matched with another individual, it’s going to delete both users through the graph so that they cannot be matched once more. The algorithm continues until all users have already been matched or there are no more users that are available match.


Among the major challenges that we went into had been that the Github API has price restricting, which stops one from making a lot of API needs in a offered timeframe. To resolve this issue, we applied a pseudo-caching system having a PostgreSQL database. Utilising the Github API’s conditional demand function, we only make the full demand to Github when they reveal that the info at each and every location happens to be changed. Otherwise, we just rely on formerly kept data that it hasn’t changed since we know.
