CodeChef is a not-for-profit educational initiative started by Directi more than a decade ago. We started with a dream of seeing an Indian team winning a gold medal at the ACM ICPC World Finals. In its quest for the same, CodeChef has built a self-driven community of the world's best programmers. Today more than 1.3 million competitive programmers from 180+ countries learn from CodeChef. CodeChef has been hosting monthly programming contests regularly for 10 years now. Its platform has assessed 92 million+ code submissions to date, and over 30000 organizations are being impacted by CodeCheffers worldwide. It also organizes SnackDown - one of the world's largest global programming competition whose last edition drew participation from 140+ countries. Since 2017, CodeChef has started providing India's only industry-ready certification in Data Structures and Algorithms, and 1800+ programmers have been certified under the same.

I can recommend Standard Notes as an alternative. https://standardnotes.com/ Works well on all paltforms, desktop and mobile. The sync works also great. It also backs up to text files on your computer, so that you can back up your files with your regular backup process and you can also easily move away if you would like to one day. - Source: Hacker News / 5 months ago

This certainly could be useful for me personally, but it would need more functionality. I think the _full_ project could be very useful though. However I would ask, how is this different from e.g. https://standardnotes.com/ and other note systems available ? - Source: Hacker News / over 2 years ago
