The Open Source Development Surprise

We’ll talk about the surprising ways open source is different from regular 9 to 5 development, the importance of people, technology and teamwork. We’ll go through real open-source changes affecting millions of developers in and see how the people behind them work and how to get involved yourself.


Benjamin is a collaborator of several open source libraries (bluebird, sinonjs, mobx to name a few), node.js core collaborator and developer @ working on really cool test automation stuff.

Challenges Track


The challenges dashboard >>


The challenges are stand-alone problems, designed for a team of 1-5 members to solve within the weekend. You will be scored for technical elegance and creative interpretation. The challenges are open ended and you are encouraged to come up with extra features and analytical insights.


open cities

  1. Municipality Comparator - develop a tool that will compare between municipalities based on socio-economic, geo and demographic parameters of your choice + funding transferred from the state budget. Use BudgetKey API and LAMAS data (details).

  2. Safe roads - analyze traffic accident data and find trends, to identify most dangerous roads and intersections in the city.


budget key

  1. In good company - analyze data about companies regarding their business with the government, to be able to cluster and tag companies.

  2. The people behind the NGOs - analyze amutot data to detect connections between organizations based on address, founder names etc (details).


open knesset

  1. Parse text protocols from Knesset committees (details).

  2. NLP - analyze protocols (Hebrew), to identify subjects of discussion etc.


open public transport

  1. Mobile - develop an app for passengers to report late train and bus arrivals.

  2. Unsupervised ML - detect anomalies in bus trip data, such as late departures, deviation from planned route, unusual delays along the route etc. Data: real-time GPS bus trips (from SIRI)

  3. Web - create a Leaflet map that plots the bus routes.
    Show shape of planed route, stops, other lines that pass at the stop, trip info etc.


open pension

  1. D3 - create a beautiful visualization of financial markets data.

    The portfolios of institutional investors (pension funds, insurance companies etc who manage our savings) hold a wide variety of assets - from stock, to derivatives to real estate. We want to see what our money is doing.

  2. Analyze the data about the distribution of assets of institutional investors. (example).



Data: road accidents, published by למ”ס.

  1. Explore the trends in fatal casualties, and look for explanations.

  2. Explore patterns in accidents related to drivers, interchanges, injured etc.



All of this data stuff needs some servers to run on reliably. If you like talking to servers and debugging weird infrastructure problems this Kubernetes challenge is for you.

Projects Track

The projects are on-going, with existing teams that you can join and delve into existing code base. Each project has a list of issues of different complexity levels, from solving bugs to adding features. Projects are a good pick if you can’t stay for the whole weekend, if you find a particular project interesting and if you want to work with a strong team. Or if you’re bored with competitions.


Dynamic map of road accidents based on LAMAS (למ"ס) database, that helps to identify most dangerous roads and spot a faulty infrastructure, as part of our Vision Zero agenda to eliminate fatal accidents.


open pension

1.6 trillion shekels of our pension savings are managed by pension funds. Is this money working for us and how does it effect the country's economy? Open Pension provides an insight of pension funds investment policy - for responsible and transparent management.


budget key

Explorer the state budget, see how funds are allocated and how the money is spent. Find out what do government offices pay for, which companies they contract and which organizations receive government subsidies. Behind the BudgetKey website is a rich database combining many official data sources.


open law book

This is the only open database of the full text of Israeli laws (all amendments included), built on Wikitext platform, and now linked from the Knesset's National Legislation Database.


open knesset

What did our members of Knesset vote for or against? In which committee meetings did they participate? Which legislation did they support? Open Knesset collects this data from the knesset API, and allows a deep analysis of all parliamentary activity.

Which bus line is always late?

open bus

Why is your bus always late? Which bus lines are the most and least accurate, in which cities and which times of the day? OpenBus project is trying to figure it out by analysing real-time bus trip data from the Ministry of Transportation API.
