UPD: Our friends at Harbour.Space also have a message for you:
Hello Codeforces!
We hope your summer is going well!
Last Friday we finished the second edition of the Tech Scouts Summer Camp, with 70 participants, 20 different nationalities and many solved problems. We had 6 participants with a full scholarship thanks to the collaboration between Harbour.Space and Codeforces and we are working on increasing this number next year.
We would also like to remind you that we offer scholarships for our technical programmes, such as Computer Science, Data Science and Cyber Security.
They are set in such a way that doesn’t require additional applications — we believe in merit and potential, and so what you put in your application to the university will be our criteria.
You could be just the diamond we’re looking for, but you’ll never know unless you apply!
