  • Quality Variability
    The quality of user-submitted challenges can be inconsistent, meaning not all katas are equally useful or well-designed.

    While great for practice, Codewars does not provide comprehensive tutorials or in-depth explanations, which are often needed for mastering complex concepts.
  • Time Consumption
    The addictive nature of the platform can lead to spending excessive time on solving challenges, potentially detracting from other learning activities.

Possible disadvantages of Readwise

  • Subscription Cost

  • Limited Functionality Without Subscription
    While there is a free trial available, many features are gated behind a subscription, limiting the usability of the free version.
  • Learning Curve
    Despite its overall user-friendliness, some users might find a learning curve when initially setting up and configuring the system to suit their needs.
  • Dependence on Third-Party Integrations
    Readwiseโ€™s value is largely dependent on its integrations with third-party services, meaning any changes or issues with those services can impact its effectiveness.
  • Privacy Concerns
    Since Readwise collects and stores data from multiple reading platforms, there may be privacy concerns regarding how this data is handled and stored.

Readwise Reviews

  1. Great help to review books

    I 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!

Codewars mentions (160)

  • 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 / over 2 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: almost 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?
    There is a website called codewars.com where you can select problems of varying difficulty for the language you need. It is very helpful for learning. Source: about 3 years ago

  • Relego, a free, self-hostable alternative to Readwise
    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 didnโ€™t want to get up; I was tired. - Source: dev.to / 28 days ago
  • Exporting Mac OSX Book Highlights into an Obsidian Vault or Markdown Files
    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
  • Show HN: I combined spaced repetition with emails so you can remember anything
    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
