The RIPE NCC and iNOG organised a hackathon in June 2018, in Dublin. This review celebrates the achievements of the hackathon, invites you to use our results, and welcomes your contributions for future hackathons!

Together with iNOG, RIPE NCC successfully held its seventh hackathon in Dublin this June.

It all started at the previous hackathon in Copenhagen - Hackathon Version 6 - in November 2017. Cristian Sirbu, one of the iNOG organisers, enjoyed our event so much that he wanted us to hold the next event together, in Dublin. 

It all worked out wonderfully. We had a great lineup of activities: 

  • Thursday evening: iNOG::10
  • Friday: Last-minute preparations, a hike in the Ticknock hills and a visit to the local hackerspace TOG
  • Saturday & Sunday: Two days of hacking

The results were impressive. Here is a quick summary of the hackathon in numbers:

  • 8 finished projects
  • 40 happy people
  • 3,309 square inches of pizza devoured
  • 234 cups of coffee consumed
  • and finally, 226 beers enjoyed!  

The RIPE NCC is grateful for the enthusiasm of the iNOG organisers, the support of our sponsors (ZPE Systems, ThousandEyes, Facebook, PanSift & RedBit Networks), the warm welcome by DoSpace, and the contributions of all the participants! 

Combining the NOG and the Hackathon

The decision to schedule the iNOG meeting and the hackathon back-to-back turned out to be fantastic! Many of the participants registered in advance for both events. We "recruited" several additional hackathon participants from the iNOG attendees, and some of the presentations turned into projects, which were worked on during the weekend!

It worked out so well, that we have an invitation to follow this format again in 2019, with GRNOG. Stay tuned for more details!

 A Recipe for Success 

With the combined powers of the experienced iNOG volunteers (Cristian Sirbu, Lorcan Boyle, Donal O'Duibhir), the great host from DoSpace (Graham Barker), and our own hackathon-super-organiser Vesna, everything went as planned. Here are some of the elements that participants appreciated the most: 

  • DoSpace: A beautiful co-working space with an atmosphere that fosters creativity
  • Lots of good food from the local catering company KC Peaches, pizza from Basil, and dinner in HQ
  • T-shirts galore, with the hackathon icon, and as gifts from our sponsor: ThousandEyes 
  • Excellent coffee provided by 3FE, famous Dublin baristas, generously sponsored by Facebook
  • Good locally brewed craft beers! 
  • The visit to the local hackerspace, TOG 
  • And the ultimate reward - stroopwafels, of course!

Eight Projects 

Since the topic 'Tools to help Network Operators', was very broad, the projects were quite different. Eight teams were formed, out of a total of 12 suggested projects on themes ranging from more automation, to better visualisation of the measurements data about the reachability of their networks, to generating alerts. The teams presented their work on the Sunday evening at the end of two days of collaborative work.

You can view all the software & slides created during the hackathon. Here are the projects, in order of appearance:

RIPE-Atlas-tools project

Team: Henrik Lund Kramshøj, Kemal Sanjta, Annika Wickert, Keith Gaughan, Graham Hayes, Guilherme Urban, Emile Aben

Goals: Improving existing Command Line Interface tools for processing RIPE Atlas data.

Achievements: fine-grained probes selection, and proposed changes to the traceroute: faster, more colourful, and with the graph output. They generated lots of pull requests.  

BioRouting table

Team: Maximilian Wilhelm, Oliver Herms, Philip Berndroth, Daniel Czerwonk, Serge Bazanski 

Goals: Additional features for BioRouting 

Achievements: Route server feature was implemented, and GRPC configuration maintenance 

AS Interdepandancy VIZ

Team: Pedro Vaz, Sofia Silva Berenguer, Iain Geddes 

Goals: To visualise the relationship between Autonomous System Numbers (ASN)  

Achievements: Backend data collection, TinyFlask for frontend, successful demo & a blog post 

GoNetconf Pack

Team: David Gee, Renne Neuman, Patrick Harney 

Goals: To create a pack for StackStorm that performs netconf requests 

Achievements: Successful demo! gogetconf code refactored, interface created & tested, a "pack" with 2 action created 


Team: Matt Oswalt, Tudor Stefan Tabacel Manea, Jasper den Hertog, Guilherme Loch Waltrick Goes 

Goals: Implement the detection of RIPE Atlas measurements data "events" in StackStorm

Achievements: Two kinds of events were detected and demonstrated (probe disconnections, baseline discrepancy)


Team: Rodrigo Magno, Christian Bachert, Ondrej Velicka, Joao Cancelli, Loke Berne

Goals: Dynamic GMaps weathermap creation from collected network state

Achievements: Lots of learning, and a successful demo of the results: routers on the map! 


Team: Ronny Trommer, Craig Gallen, Patrick, Colin MacGiollaEain 

Goals: Additional features for OpenNMS

Achievements: Telemetry / SNMP streaming data integrated in OpenNMS; good documentation 


Team: Nikos Roussos, Petros Gigis, Vasileios Giotsa

Goals: Create a tool that can give routing insights on ASes AS using the RIPE Atlas and RIPE RIS services

Achievements: Three implemented features (suggest new peering, automatically interpret BGP communities, detect routing incidents based on community changes)

Here's the shortcut (again) to the collection of software & slides, and more links to articles & photos:  

The jury, consisting of Vesna Manojlovic, Cristian Sirbu, Lorcan Boyle, and Brendan Cleary, had a hard time deciding to whom the stroopwafels should be given!  In the end, the jury decided to award stroopwafels in three categories:

  • For the best team-work: two groups working as one, on StackStorm topics!  
  • For the best cooperation with others: the AS Interdependency VIZ team!! 
  • For the most-complete project: the RIPE-Atlas-Tools team!!!   

Having Fun

Extra activities are important parts of the hackathon - and vital to keep people energised to work over the weekend. This time, there were some fun, new things to do:

  • Arcade machines, for some geeky relaxation 
  • Hiking, for the more nature-loving nerds 
  • Ice-cream, since Ireland had an uncharacteristic heat-wave  
  • And the opportunity to win the OculusRift, at a quiz, sponsored by Facebook

Once again, it was clear that hackathons are great as temporary spaces for group problem-solving and prototyping! They foster creativity, enhance cooperation, and are useful. All the tools and software are available. Please feel free to use them and hack further.

We also invite you to go to other hackathons! Check out the new calendar applet. This is a collection of all the hackathons that we know of on RIPE Labs: 

The next RIPE NCC hackathon is in October in Amsterdam, just before the RIPE 77 meeting
