    While great for practice, Codewars does not provide comprehensive tutorials or in-depth explanations, which are often needed for mastering complex concepts.

    The addictive nature of the platform can lead to spending excessive time on solving challenges, potentially detracting from other learning activities.

  • Of recursion and backtracking
    Recently, I was working on a coding kata on codewars.com. Early on, I started thinking that a potential solution might utilize recursion, a concept that involves a function calling itself. However, I quickly realized that my grasp of recursion was not as solid as it needed to be for this task. In this post, I will share the insights gained from deepening my understanding of recursion while working through the kata. - Source: dev.to / almost 3 years ago
  • 4th year, about to fail an entire semester's worth of classes.
    Get more involved. Look into internships and junior SWE positions to get a sample of what you'd be applying for once you graduate. Solve coding challenges, start working on a portfolio of your personal works. I recommend codewars.com for coding challenges, it's fun. Source: over 2 years ago
  • Beginner with C++ looking for direction
    I'd recommend to play around with some basic coding challenges on leetcode.com or codewars.com. If the course prepared you well you won't find this useful, but playing around with them will make sure that you are comfortable with basics such as loops, if statements etc. Source: about 3 years ago
  • Can you guys recommend an efficient way to learn in advance IT para sa mga walang alam?
    I would advise for you to start with Python, it's a beginner-friendly programming language and it'll help with wrapping your mind around things. Play around with it, perhaps do some katas on CodeWars and you'll be set. Source: about 3 years ago
  • How do I develop programming logic?

  • Kobo can run apps now
    My wife bought a kobo as it allows her to use the local libraries ebook collection, rather than spending hundreds of pounds at amazon for the kindle. It was starting to die and had screenglitches. After a bit of debug, it turns out that hacking the kobo is dirt simple. You open up the back, and replace the SD card. Thats it.
