About Swenest
Swenest is an innovative educational platform designed to bridge the gap between traditional coding practice and the realities of software engineering. Created by software developer Ashish Waikar, Swenest focuses on a critical skill that most platforms ignore: how to navigate and understand unfamiliar, real-world codebases.
Instead of artificial problems or straightforward prompts, Swenest uses real merged GitHub PRs as tasks. Users are given symptom-only descriptions, challenging them to investigate and find the root cause themselves. To support the learning process, the platform features progressive AI hints that guide users without giving away the solution, along with an AI judge that grades solutions against the actual merged fix. Combined with an XP-gated difficulty progression, Swenest offers a uniquely structured and gamified environment for professional growth in tech.
Pros of Swenest
- Uses real merged GitHub PRs instead of artificial coding problems
- Trains users on navigating unfamiliar, real-world codebases
- Provides progressive AI hints that guide without spoiling the answer
- Features an AI judge to grade solutions against actual merged fixes
- Gamified learning experience with XP-gated difficulty progression
Cons of Swenest
- Focuses heavily on bug fixing and PR navigation rather than building applications from scratch
- Requires prior programming knowledge to tackle real-world codebases
- Difficulty progression is strictly gated by XP
Frequently Asked Questions
What makes Swenest different from other coding platforms?

About SpaceSim
SpaceSim is a free, browser-based universe simulator designed for space exploration and education. Created by Romain Simon, the platform allows users to instantly journey through the cosmos without the need for any signup or account creation.
With SpaceSim, users can travel through a real-time, UTC-driven 3D Solar System and inspect source-linked scientific state data. The simulator also features the ability to observe Earth from a pinned NASA ISS trajectory, build procedural stars, visit compact objects, and collect virtual postcards of your discoveries.
To ensure transparency and educational accuracy, SpaceSim clearly labels all of its content as scientific, reconstructed, representative, procedural, experimental, or promotional.
Pros of SpaceSim
- Completely free to use with no signup or registration required
- Runs directly in your web browser with no installation needed
- Provides a UTC-driven 3D Solar System with source-linked scientific data
- Clearly labels content categories (such as scientific, procedural, or experimental)
Cons of SpaceSim
- Requires an active internet connection to run the browser-based simulation
- Features and exploration scale are limited to the simulator's built-in digital environment
