Are you interested in reproducible code and open science? We have the perfect opportunity for you! 

As part of a pilot project between TU Delft and CODECHECK, we are looking for researchers who would like their papers or projects to be “codechecked” during a live code-checking hackathon on 18th September 2023.  Sign up and find out more on the event page! A codecheck is a light-touch independent peer review to check that your code and data can generate the computational results in your paper or project (see more details here). 

What do you get? 

  • A codechecker will work with you during the session to check whether your code and data can be run by others to generate the same or similar results. 
  • The codechecker will work with you to resolve any issues found during the code check, and make your code as reproducible as possible! 
  • Upon completion, your paper will receive a codecheck certificate that confirms your results could be reproduced.  This can be shared, e.g., with potential journal editors, to enhance the visibility and reproducibility of your work.  

By participating, you contribute towards making science more open and transparent! 

What should you do? 

Are you interested in participating in this event, and help contribute to promoting code reproducibility? Send an email to by Monday, 21st August 2023 with a brief description of your paper/project, and links to your code and data. This could be code related to: 

  • A paper that you have recently published 
  • A preprint that is publicly available 
  • Code and results files that have been or will be deposited in the 4TU.ResearchData repository, preferably using Git 

In each case, the code and data underlying the paper should be openly available, or you plan to make them available once the paper is published. Selected papers/project will be notified in early September 2023 and invited to join the hackathon. Alternatively, if you are interested in learning more about the codecheck process, why not contact us about the pilot project and volunteer to become a codechecker?  

Interested but still have questions? Ask us!
