Recently CodeChef hosted a hackathon and we could only find some of the projects on the main discuss but I went to the special discuss site of the hackathon just for fun today only to find all these great projects these people have contributed to. They include CodeChef Android/IOS apps, some web-apps (which are far better on front-end then current CodeChef :P) and some awesome IDEs (something like Topcoder arena) and our favourite CLI tools as well.
You can visit the link: https://alibabacloud.discuss.codechef.com/ for their respective links and video demos. The guys have put in a lot of effort and lets take some time and appreciate their work
Try each of them out, you’ll find something which you wanted from along time
