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.

SimplenoteI've started with Simplenote years ago, at the time I was happy but it became clear pretty quickly that it was too basic. But to be fair, it's basic and free. Keep in mind it's unencrypted.
Was looking for an alternative for OneNote, so I found it here. I like how simple the interface is and the UI is very simple. It's good for what it is, but there is no sorting/topic system which makes it difficult to find specific notes for specific topics. Other than that, it's a good note system.

Leetcode is good to learn basic algorithms because problem statements are usually straightforward. Competitive programming has much wider range of problems. Most popular sites for cp are codeforces.com , atcoder.jp, codechef.com . Source: over 2 years ago
Learn Java with hands-on experience. I personally used codingbat.com a lot, but I've heard good things about codechef.com, which appears to even have a competitive option. Source: over 3 years ago
For practicing algorithms, use any of the freely available websites like https://hackerrank.com https://codechef.com https://projecteuler.net A structured set of practice problems are available at https://www.interviewbit.com/courses/programming/ Avoid https://geeksforgeeks.org because it has a ton of material but very poor quality control.

These all have sample problems to solve Hackerrank.com edabit.com codewars.com codechef.com and there are tons more. Best of luck to you. I am at about the same level myself. I really like these sites. Source: over 4 years ago
I've been looking to migrate away from https://simplenote.com to something else and I've been dragging my feet. However, what's happened in the past 2 weeks with the CEO was the push I needed to resume looking for another solution. I've landed on Obsidian.md. I actually prefer Simplenote over Obisidian, because Simplenote feels smoother and the online web app is great, but I've decided that having more control... - Source: Hacker News / almost 2 years ago
I use https://simplenote.com - Syncs across multiple platforms. - Plaintext based (with MD support). - Search + edit UI similar to https://notational.net and https://brettterpstra.com/projects/nvalt - Simple to publish/share notes - Free (as in beer and speech) --- If I used MacOS or there were web versions, I would love to use the following (they are all better at plaintext than SimpleNote): -... - Source: Hacker News / almost 2 years ago
Bookmarks serve two purposes: - Quick access to commonly used links. For this, I built https://multi-launch.leftium.com - Saving a link for future reference. Often I want to also save plain text notes for future reference, so find myself using https://simplenote.com I have also used https://www.bkmks.com to save links. I'm working on an app that will help save and organize everything: bookmarks, notes, and tasks. - Source: Hacker News / about 2 years ago
It doesn't meet the poster's needs, but Simplenote is still a thing for people who want text-only notes, Markdown, and easy access to plain text files. It got acquired by Automattic a few years back. https://simplenote.com/. - Source: Hacker News / about 2 years ago
Https://noteplan.co is a very similar app. Unfortunately I couldn't use it because it was limited to iOS devices (a web version is in development). - One thing missing in craftnote is search. That is a must-have feature for me. - I also like being able to publicly share notes with a (short) URL. See https://simplenote.com for an example of how this is done. Nice job with allowing your app to be usable without... - Source: Hacker News / about 2 years ago
