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.
Codechef ReadwiseI imported my kindle highlights, as many others. Now I daily review some highlights (thanks to a dashboard, I am motivated). And where I didn't create highlights, as I only listened to the audiobooks, I get the highlights from others. It also allows to create beautiful quotes. It adds the book cover and matches quote and background with colours found on the book title! Really nice!

Anyway, as I reached the end of the chapter, I wanted to read my Readwise's daily recap. However, my iPhone was in other room. I didnโt want to get up; I was tired. - Source: dev.to / about 2 months ago
The only highlights that Readwise retrieves semi-automatically are from the books I buy from Kindle, by going into the Readwise app and clicking a button. If I upload them to Kindle or need highlights from the Apple Books app, I have to open the book, go to my highlights, select them all, and then email them to a Readwise email address. - Source: dev.to / over 1 year ago
Readwise also has this feature. I get a daily email with a random assortment of highlights that have been pulled in from multiple sources (Reader, Notion, Kindle, etc.) The product benefit in their case is that it's kind of like Zapier, but for notes. https://readwise.io/. - Source: Hacker News / over 1 year ago
