Morning.dev

The worst test suite I ever inherited had 400 tests, and I trusted about six of them. The rest were either testing implementation details nobody cared about, duplicating each other, or so tightly coupled to internal function names that a harmless refactor broke thirty tests for no real reason. Reading that codebase taught me more about what not to do than any greenfield project ever has. So when ...

One breakout title = 99.9% of a studio's traffic: what Roblox's own public API shows about "genre template" games

Roblox exposes game and group stats through public, unauthenticated endpoints — no login, no scraping tricks: GET https://games.roblox.com/v1/games?universeIds=<id>,<id>,... GET https://games.roblox.com/v2/groups/<groupId>/games?limit=50 I used them to pull the full public games list for a few independent creator groups that each ship multiple games in the same cheap-to-...

Code Signing for Android/iOS

Every dev course teaches you to build the app. Almost none teach you how to actually ship it. I found that out the hard way on my first job — no signing, no publish, no exceptions. So I wrote the full setup, both platforms, both ways: → Android: keystore via CLI and Android Studio's GUI → iOS: manual signing (certs, App IDs, provisioning profiles) AND automatic signing → The exact steps before e...

The Day My Automation Reported Zero Failures While Quietly Wasting a Third of Its Work

The symptom The log looked clean. Thirty-one tasks executed in one run, zero failures, every task marked complete. If you only looked at the dashboard, it was a perfect day. Then I actually read the output files instead of the exit codes, and found this: an article titled "Silent Retries Are Hiding Your Rate-Limit Exhaustion: A Circuit Breaker for LLM API Calls" sitting in the output f...

What Really Happens When 25 Lakh People Click “Book” at the Same Time?

Imagine this. Tatkal booking opens at 10:00 AM. At exactly 10:00:00, around 25 lakh people click the Book Now button. There are only 4 seats left in your coach. So the obvious question is: How does the system decide which 4 people get the seats? Is it literally first-come-first-served at the millisecond level? And what happens to the other 24,99,996 requests? This is a great system desig...

3 Traps I Hit Building Apify Pay-Per-Event Actors as a Solo Node.js Dev

Why Apify Store? As a Node.js/TypeScript engineer with a day job, I've been looking for a side project that fits into 15-minute-to-1-hour fragments of time, doesn't require sales calls or synchronous client work, and doesn't need me to build my own distribution channel. Apify Store checked those boxes: it's a marketplace, so discovery (search, categories) is handled by the platform. Yo...

Arrays vs Linked Lists: Why the Textbook Winner Loses on Real Hardware

📺 Prefer to watch? 90-second YouTube Short · 💬 Telegram Originally published on software-engineer-blog.com. Every data-structures course teaches the same table. Array: insert O(n), because you have to shift everything. Linked list: insert O(1), because you just repoint two pointers. Conclusion: if you insert a lot, use a linked list. Then you write both, measure them, and the array wins anywa...

Ingesting the Solana Firehose: High-Throughput Decoding with Rust

In Part 1: Economics & System Design, we established the blueprint. We proved that by optimizing Helius RPC subscriptions and decoupling our ingestion layer from our database using NATS, we can track all Solana swap volume without burning our runway on infrastructure costs. Now, we have to actually build the ingestion engine. When you are dealing with thousands of transactions per second acr...
