| Scalability is not performance |
| |
| |
| Boosting scalability in distributed systems isn't just a mad dash for speed. It's about morphing resources to tackle shifting demand. Nail scalability, and you balance infrastructure costs with job handling efficiency, all while juggling resource utilization at a sweet spot around 0.5. Crave a drama-free experience? Systems must scale like an expert balancer, adapting to the rollercoaster of workloads thrown their way. |

| Understand CPU Branch Instructions Better ✅ |
| |
| |
| Branch prediction matters. Why? About a quarter of instructions are branches, and modern CPUs nail an accuracy above 90%. Yet, those often-pesky branches can choke CPUs, stalling instruction flow. So, take a wrench to your if-else logic. Trim indirect branches whenever you can—your CPU will thank you. |

| Crawling a billion web pages in just over 24 hours ✅ |
| |
| |
| Imagine tearing through 1 billion pages in a single day on a shoestring budget. This crawler pulled it off with 12 nodes and some savvy async maneuvering. But here's the kicker: it wasn’t the fetching that choked the CPU. Nope, it was the parsing. Today’s web behemoths, bloated with JavaScript and other digital detritus, laugh at good old HTML parsers. So, if dynamic rendering gets on your to-do list, brace for sticker shock. |

| Containers: Everything You Need To Know |
| |
| |
| cgroups and namespaces anchor Linux containers, isolating resources and processes like gatekeepers with a mission. On macOS and Windows, these containers ride in VMs with WSL2 or LinuxKit, putting on their "welcome to the virtual world" hats. Enter runC, executing OCI-built images with isolation flair, while containerd strides in, running containers without deep kernel surgery, thanks to a handy gRPC API. Now meet Podman, which shuns daemons and says, "I'll do it myself," enhancing security while drawing a line between mere mortals and daemon-dependent Docker. When juggling multiple hosts, behold Kubernetes, the conductor orchestrating deployment and management—a rock star for microservice architecture fans. Then, there are Distroless images—thrill-seeking minimalists, stripping to vital bits to boost container size and performance. And for those longing for the future now? WASM containers cleverly exploit Docker runtimes, embracing platform-agnostic, browser-friendly antics like it's their destiny. |

| How I build software quickly |
| |
| |
| Software development requires balancing quality and speed. Aim for an "8 out of 10 score" code, finish on time, use rough drafts spiked with bugs, make small focused changes, and flexibly adjust requirements. Effective devs also hone code reading, data modeling, scripting, debugging, and break-taking skills. So drop the perfectionism, embrace the messy drafts, and get things done efficiently! |

Web Components: Native and framework-agnostic, perfect for reusable UI with Shadow DOM flair. single-spa: Juggles multiple SPAs with the finesse of a circus, though it gets chatty. Module Federation: Real-time module confab, shackled to Webpack, yet import maps are optional. Each has its quirks and perks for micro-frontends—choose your weapon wisely. |

| Lessons from scaling PostgreSQL queues to 100K events ✅ |
| |
| |
PostgreSQL juggles 100,000 events per second. Just needs some index wizardry and query twerking. The problem? Table bloat and Write Amplification. Gross.
Enter the mighty COPY—it bulldozes through bulk data, politely ignoring the usual Insert drag. And those recursive CTEs? They pull off loose index scans, giving performance a sly nod minus the native support. |

| Parsing 1 Billion Rows in Bun/Typescript Under 10 Seconds ✅ |
| |
| |
| Bun tries to swallow files over 4GB and promptly chokes. The culprit? Its Buffer caps out at 4GB. The fix? Slice files into chunks under 4GB but keep the buffer lean, no more than 128KB, to keep things zippy. Pull out the big guns—workers. This move fires up all CPU cores, slashing processing time from 18.65s to 9.22s. And yep, go manual with UTF-8 parsing. It's Bun's single-threaded quirk, and it's kind of charming. |

| Asynchrony is not Concurrency ✅ |
| |
| |
| Asynchrony isn't a twin to Concurrency in Zig. It juggles async tasks without leaning on multi-threading, letting sync and async mingle harmoniously. Concurrency craves overlap, but Zig's savvy. When resources get stingy, it smartly reverts tasks to synchronous, dodging drama like deadlocks or sudden crashes. |
