CodeRifts detects breaking changes in OpenAPI schemas on every pull request. It scores risk across 4 dimensions (revenue impact, blast radius, app compatibility, security), enforces governance policies before merge, and translates technical API changes into business impact — blast radius, affected clients, and estimated cost.
Works with GitHub, GitLab, Bitbucket, and any CI/CD pipeline. Zero config. Free to start.
Key features: - Breaking change detection with risk scoring (0-100) - Policy engine: breaking budgets, freeze windows, approval matrix - Economic impact estimation: cost and engineering effort - Security analysis: auth changes, sensitive field exposure - Auto-changelog and semver suggestions - GitHub App, GitHub Actions, GitLab CI, Bitbucket Pipelines, REST API, CLI
Codewars CodeRiftsCodewars is recommended for beginner to advanced programmers who enjoy learning through practice and are interested in improving their algorithmic thinking and coding skills in a gamified environment. It is particularly beneficial for those preparing for coding interviews or seeking to reinforce their programming knowledge in a fun and interactive way.

Currently in beta, onboarding early adopters
CodeRifts's answer:
CodeRifts is the only API governance tool that combines breaking change detection with risk scoring, policy enforcement, and economic impact estimation — all delivered as a zero-config GitHub App. It does not just tell you what changed, it tells you how dangerous it is, who it affects, and what it will cost to fix.
CodeRifts's answer:
A field rename broke a POS system across 19 restaurants for a week. The PR passed code review, all tests were green, nobody checked the API schema. CodeRifts was built to catch this class of problem before merge — automatically, on every pull request.
CodeRifts's answer:
Most tools only diff your OpenAPI specs. CodeRifts goes further: it scores risk across 4 dimensions, enforces governance policies before merge, estimates migration costs in dollars and engineering hours, and works with GitHub, GitLab, Bitbucket, and any CI/CD pipeline. One YAML file replaces review meetings.
CodeRifts's answer:
Senior backend engineers, platform engineers, and staff engineers at companies with microservices architectures who need to prevent breaking API changes from reaching production.

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
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: almost 3 years ago
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
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
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
