EMKC Coding Challenges is a page offering practical coding tests in 17 available languages, with points awarded based on difficulty. The page lists easy, medium and hard challenges, states that new challenges are being added, and notes that a challenge can be completed up to 17 times, one for each language.
Site offering CSS practice challenges organized by difficulty levels from Easy to Insane, with named exercises such as Hello World and Clock World. It is presented as a way to practice becoming a better web developer and learn a new trick every day.
Typing.io is a typing tutor for programmers whose lessons are based on open source code in languages such as JavaScript, Ruby, C, C++, Java, PHP, Perl, Haskell and Scala. It covers symbol keys, and the site describes it as free with sign-in.
Nightmare is an introductory course on binary exploitation and reverse engineering built around CTF challenges. Its materials are structured linearly and include documented write-ups for each challenge, with most modules offering multiple problems per topic so learners can apply an attack technique to different iterations. The course uses only free and open source tools, and its static site is built with mdbook.
A beginner's guide to capture the flag (CTF) hacking competitions. It explains what a CTF is, describes jeopardy-style CTF categories such as reverse engineering, Pwn, crypto and web, and covers logistics, finding CTFs and reverse engineering resources.
CTFlearn is a platform for learning and competing in capture-the-flag challenges. It offers hundreds of challenges for testing skills and a community for learning cybersecurity with others, and describes itself as a beginner-friendly way into hacking. A free account can be created.
Leetcode provides educational videos, lessons, tutorials, or self-learning resources.
