solo built a centralized exchange with a real-time matching engine
skinned it like super mario because normal UIs are boring
this is what overengineering a side project looks like ↓
China's new AI (GLM 5.2) beat the US-banned Fable 5 on key benchmarks at a fraction of the cost, showing that banning AI doesn't stop competitors

OpenRouter launched Fusion API
it combines multiple cheaper AI models together to match the smartest AI (Fable 5) at half the price.
Three budget models working as a team beat top solo models like GPT-5.5 and Opus 4.8.
Teamwork wins

Before you build ANYTHING, ask yourself these 5 questions:
1️⃣ Who actually has this problem?
2️⃣ Will they pay to fix it?
3️⃣ What’s the smallest version I can test?
4️⃣ How will I know if it’s working?
5️⃣ What happens if no one cares?
Skip this checklist → waste months building the wrong thing.
Do it first → save yourself the heartbreak. 💔
10. Run a post-launch review Track the KPIs from
step 1. Did it actually work?
If something broke → run a blameless postmortem.
Don't blame people. Fix the process.
9. Set up observability Logging.
Metrics dashboards.
PagerDuty-style alerts.
SLAs (Service Level Agreements) and SLOs (Service Level Objectives) define how reliable you promise to be.
You should know it's broken before your users do.
8. Ship with canary releases (Gradual Rollout) Never flip 100% on at once.
Use feature flags.
Roll out 5% → 25% → 100%.
Watch error rates.
Roll back instantly if something's off.
7. Use a staging environment A near-identical copy of production.
Deploy here first.
This is your QA (Quality Assurance) layer.
Test like it's real —> because it almost is.
4. Set up the scaffolding (Project Skeleton)
Repo structure, CI/CD pipeline , linting, testing framework, env configs (dev/staging/prod).
All before feature code.
Feels slow.
Pays for itself in 48 hours.
5. Build with PRs (Pull Requests) Small commits.
One thing per PR.
Every PR gets a code review.
Write unit tests WITH the code, not "later."
Later = never.
