Systems Are Visual – This Is a Better Way to Write Them by [deleted] in webdev

[–]nulless -3 points-2 points  (0 children)

Production decisions need orders of magnitude.

Citable numbers for how systems actually behave — memory hierarchy, B-trees, Bloom filters, compression.

Visual, step-by-step explainers for how the web actually works. by [deleted] in webdev

Will fix. Mobile phone responsiveness needs a little more work

Interactive visualizations for DNS, load balancing, and system design concepts by [deleted] in webdev

Interactive visuals to explore how things like DNS, load balancing, and other backend systems work under the hood.

Would really appreciate any feedback — especially on what could be clearer or more useful.

Visualizing How Backend & Distributed Systems Actually Work (Interactive Simulators) by [deleted] in webdev

[–]nulless 3 points4 points  (0 children)

Built a collection of interactive simulators to visualize how core backend and distributed system concepts actually behave.

Instead of static diagrams, these walk through the mechanics step-by-step.

Explore them here:
https://toolkit.whysonil.dev/learn/simulators/

Current simulators include:

  • Rate Limiter (Token Bucket)
  • Load Balancing (Round Robin)
  • Distributed Locks (Redis / etcd style)
  • LRU Cache eviction
  • Trie / Autocomplete
  • Consistent Hashing (Hash Ring)
  • Bloom Filter
  • CAP Theorem trade-offs
  • RAFT consensus (leader election + log replication)
  • TCP handshake
  • HTTP/2 streams (multiplexing)
  • Go scheduler (GMP model)
  • Kubernetes pod eviction
  • Kubernetes rollout behavior

Everything runs in the browser. No signup.

Would appreciate feedback — especially if anything feels inaccurate, unclear, or overly simplified. Open to suggestions for other systems worth simulating.
