It was the middle of a Friday afternoon, and I was sitting in the front row of a local mosque. The room was deathly quiet, the kind of silence that amplifies every heartbeat. Suddenly, three rows behind me, a phone erupted with a loud, brassy ringtone that seemed to go on for an eternity. The man scrambled to silence it, his face turning bright red as he fumbled with his screen. I felt his humiliation deeply. In that moment, I realized that modern smartphones—despite their intelligence—are remarkably stupid when it comes to context-aware social etiquette. We live in a world of smart devices, yet we are still manually toggling our volume settings like it is 2005. I have spent years forgetting to silence my phone before a meeting, a lecture, or a quiet space, only to have it buzz loudly at the worst possible time. It is a friction point that feels trivial until it happens to you, at which point it becomes incredibly disruptive. Existing solutions often fall into two camps: over-engineered automation tools that require a computer science degree to configure, or basic calendar-sync apps that lack the nuance needed for things like location-based triggers or recurring religious observances. I wanted something that just worked, quietly, in the background, without requiring me to constantly open an app to double-check if my rules were still active. When I started building Muffle, I quickly realized that the greatest obstacle wasn't the logic of detecting a location or a prayer time—it was the operating system itself. Android, in its quest to squeeze every millisecond of battery life out of a device, has turned into a minefield for developers trying to keep background tasks alive. If you rely on a standard Service , the system will kill it within minutes as soon as the user turns the screen off. I needed a way to ensure that my background monitoring, especially for geofencing and prayer time calculations, stayed alive even when the phone was sitting in a pocket for hours. I

Want to turn a small ESP32 board into a mini arcade game you can actually play? This ESP32 OLED Mini Shooter Game uses a 128x64 OLED display and two push buttons to create a simple shooter experience. The player moves left and right, bullets fire upward, and enemies fall from the top of the screen. It is a small project, but it already feels like a real handheld game once the display starts updating. This build is a great next step after basic OLED and button tutorials. Instead of only printing text or drawing one shape, the code manages several moving objects at the same time. It tracks the player, bullets, enemies, collisions, and game-over state. The screen is divided into a simple grid. The 128x64 OLED becomes a 16x8 playfield, where each tile is 8x8 pixels. This makes object movement easier to understand because the player, enemies, and bullets move by grid position instead of raw pixel math. Why build it? This project teaches interactive programming on real hardware. The ESP32 reads button input, updates game objects, checks collisions, and draws the next frame on the OLED. That is much more active than a normal sensor display project. It also teaches timing without blocking the whole game flow. The code uses millis() to control when bullets and enemies update, so they can move at different speeds. This is useful because many embedded projects need timed actions without stopping everything else. What you'll learn ESP32 OLED display control - drawing text, squares, circles, and game objects on an SSD1306 screen. Custom I2C pins - using Wire.begin(5, 19) so the OLED uses GPIO5 for SDA and GPIO19 for SCL. Button input handling - reading two push buttons for left and right movement. Debounce logic - preventing one press from being counted many times. Grid-based game design - turning a 128x64 screen into a simple 16x8 game map. Game object arrays - storing multiple bullets and enemies with active/inactive states. Timer-based updates - using millis() to move bullets

👋 Hi DEV Community! I'm the creator of Cloud Compass , a newsletter dedicated to making cloud computing easier to understand. If you've ever felt overwhelmed by the constant stream of cloud updates, new services, documentation, and buzzwords, you're definitely not alone. I originally published this as the welcome issue of my newsletter, and I'm sharing it here because I hope it helps developers, students, and anyone starting their cloud journey. ☁️ Welcome to Cloud Compass Cloud news, concepts, and insights without the overwhelm. The cloud is moving fast. Let's make sure you're not left behind. Welcome to Cloud Compass — your guide to staying current with cloud computing while building real cloud knowledge, without feeling overwhelmed. Let's be honest. Keeping up with cloud technology is exhausting. Cloud providers release new services, features, and updates almost every week. Between official documentation, blog posts, YouTube videos, LinkedIn posts, and countless tutorials, it's difficult to know: What actually matters? What should you learn first? Where do you even begin? That's exactly why I started Cloud Compass . This isn't a newsletter written by AI or filled with copied announcements. It's written by someone who genuinely enjoys learning cloud computing and wants to make it easier for everyone else—whether you're: A developer trying to stay current A student entering the cloud world for the first time A professional who wants to understand cloud technology without spending hours reading documentation The goal is simple: Show up regularly with something that's actually useful. "I want Cloud Compass to feel less like reading tech news and more like having a conversation with someone who already read everything and saved you the time." Here's what you can expect 📰 Cloud News Roundup The most important updates from across the cloud industry—not just AWS, Azure, and Google Cloud, but the wider cloud ecosystem.

Cross-posted from noflattery.com/decide — where I ran this exact question through a council of four different frontier models and let them argue it out. You're a solo founder at ~$8K MRR. You have runway for exactly one full-time hire. Which role unlocks the most growth? (A) a second engineer to ship features faster (B) a marketer to build a real acquisition channel (C) a customer-success / support hire to cut churn and free your time (D) a salesperson to chase larger deals The intuitive answer for most technical founders is A — more shipping velocity. The case below is for C , and it's stronger than it looks. (With one caveat that can flip the whole thing — stick around for it.) TL;DR: At ~$8K MRR solo, hire customer success first if churn is real or support is eating your week . If voluntary churn is under ~3% and support is light, hire a marketer instead. Engineer and sales come later. The case for customer success first 1. Churn quietly eats growth before features can add it. At $8K MRR, 5% monthly churn is ~$400/month bleeding out before you grow an inch. Across bootstrapped SaaS in the $5–15K MRR band, the strongest predictor of reaching $50K isn't feature velocity or channel — it's net revenue retention above 90% . That's a customer-success function, not an engineering one. 2. You are the bottleneck, and support is eating you. As a solo founder you're doing product, sales, billing, and support. If support takes ~15 hours a week, that's nearly 40% of your capacity — and it's the cheapest thing to hand off. A CS hire costs less than a senior engineer or an experienced salesperson, and it buys back the hours (and the headspace) you need to think strategically again. 3. It's a research department in disguise. A CS hire generates the highest volume of qualitative signal: why people leave, what they actually use, what they'd pay more for. An engineer builds what you think users want. CS tells you what they actually need — which means the engineer you hire next buil
