ARCH: DISTRIBUTED CACHING · SINGLEFLIGHT & QUORUM LEASES

“Design a globally distributed caching tier handling 10M QPS with sub-5ms p99 latency, cross-region invalidation, and protection against catastrophic cache stampedes.”

Press ⌘1 to see Spoken Anchors or ⌘2 to see Code Implementation. All simulation runs client-side with zero network latency.

SPOKEN CUES
TTFT: 280ms TTFT
• Singleflight & Mutex Coalescing

Coalesce duplicate in-flight cache misses on the local proxy via Go singleflight or Redis distributed locks with exponential backoff.

Delivery Tip: Emphasize that this bounds downstream database queries to exactly 1 request per key regardless of incoming burst volume.
• Probabilistic Early Expiration (XFetch)

Implement optimal probabilistic pre-computation: compute early if `delta * beta * ln(rand()) > (expiry - now)`.

Delivery Tip: Mentioning the Vattani-Chierichetti-Vitter (XFetch) algorithm demonstrates deep systems literature familiarity.
• Dual-Lease Invalidation Pipeline

Broadcast invalidation deltas via Apache Kafka/Pulsar with idempotent sequence IDs and local read-repair fallback.

Delivery Tip: Contrast strict linearizable invalidation against eventual consistency SLAs for CDN edge pops.
ZONE 3: INVIOLABLE DATA BOUNDARY

Local Silicon vs. The Cloud Leak Pipeline

Why sending your live microphone and screen pixels to a third-party startup’s cloud server is an unacceptable career and security risk.

The Professor: 100% Local Pipeline

ZERO CLOUD LEAKS
01
System Audio Loopback

Audio is captured directly on macOS CoreAudio loopback into local memory buffers.

02
Metal Whisper.cpp Transcription

Speech is transcribed locally on Apple Silicon GPU/ANE in < 180ms with 0 network calls.

03
Local Context Vault Vector Search

Your resume and company dossiers are queried from encrypted local IndexedDB / SQLite.

04
NSWindowSharingNone Cloaked HUD

Answers render directly to AppKit overlay. OS flags guarantee 100% invisibility to screen share.

✓ Security Verdict: 0 bytes of candidate audio, screen frames, or resumes leave your device.

Competitors: Vulnerable Cloud Proxy

HIGH SURVEILLANCE RISK
01
Unencrypted WebRTC Streaming

Continuous microphone audio and desktop screenshots streamed to third-party cloud servers.

02
Centralized Cloud Storage

Interview questions, employer names, and answers logged on shared multi-tenant databases.

03
Generic Cloud LLM Queries

Prompts forwarded to third-party endpoints, vulnerable to rate-limiting and service outages.

04
Generic Web Window Overlays

Web-based popups without native OS window hooks, frequently captured in meeting recordings.

✕ Security Verdict: Your interview audio, employer identity, and code are exposed to third-party servers.

Radical Transparency. Zero Predatory Markups.

Competitors lock desperate candidates into $299/mo non-refundable subscriptions. The Professor gives you 100% offline local inference for $0, or direct BYOK ledger routing at cost (~$0.002/session).

Cognitive Philosophy

The Second Brain. Not a Script.

Cheating apps turn engineers into stuttering teleprompter readers. The Professor is an executive telemetry heads-up display engineered to prime your intuition, preserve calm eye contact, and surface mathematical rigor on command.

⚠️

Without The Professor (The High-Stakes Panic)

  • ✕Darting Eye Contact: Looking sideways at secondary screens or phone notes, triggering immediate interviewer suspicion.
  • ✕Robotic Reading: Reading wall-of-text LLM answers verbatim with unnatural cadence, sounding artificial and unconvincing.
  • ✕Constraint Shock: Total cognitive freeze when the interviewer pivots constraints mid-stream ("What if traffic is 100x and nodes fail?").
  • ✕Privacy Exposure: Unencrypted audio/video streamed to shady SaaS servers with zero data sovereignty guarantees.
⚡

With The Professor (Executive Presence)

  • ✓Natural Eyeline HUD: Floating ribbon positioned <50px from your webcam lens. You maintain steady, confident eye contact at all times.
  • ✓Spoken Anchor Cadence: Rapid 3-bullet talking points prime your thoughts. You speak naturally in your own authentic voice.
