| The unexpected productivity boost of Rust |
| |
| |
| Lubeno's backend is 100% Rust, providing strong safety guarantees for refactoring confidence. Rust's type checker catches async bugs, unlike TypeScript. Rust excels in tracking lifetimes and borrowing rules. Zig, on the other hand, can be alarming with its compiler choices, such as overlooking typos in error handling. |

| Everything I know about good API design |
| |
| |
This guide lays out the playbook for running tough, user-first APIs: no breaking changes, stick to familiar patterns, honor long-lived API keys, and make every write idempotent.
It pushes cursor-based pagination for heavy data, rate limits that come with context, and optional fields to keep things lean. Gives GraphQL a side-eye for being heavyweight and pricey to build.
Why it matters: The post tracks a shift in mindset—APIs aren’t just interfaces, they’re infrastructure. Built to last. Easy to adopt. Change carefully, or don’t change at all. |

| How Salesforce Delivers Reliable, Low-Latency AI Inference |
| |
| |
Salesforce’s AI Metadata Service (AIMS) just got a serious speed boost. They rolled out a multi-layer cache—L1 on the client, L2 on the server—and cut inference latency from 400ms to under 1ms. That’s over 98% faster.
But it’s not just about speed anymore. L2 keeps responses flowing even when the backend tanks, bumping availability to 65% during failures. Services like Agentforce stay up, even if they’re limping a bit.
System shift: What started as a performance tweak is now core to how Salesforce keeps its AI standing tall under pressure. |

| Lessons learned from building a sync-engine and reactivity system with SQLite |
| |
| |
A dev ditched Electric + PGlite for a lean, browser-native sync setup built around WASM SQLite, JSON polling, and BroadcastChannel reactivity. It’s running inside a local-first notes app.
Changes get logged with DB triggers. Sync state? Tracked by hand. Svelte stores update via lightweight polling, with Yjs CRDTs smoothing out conflicts.
What’s the move? A nod toward slimmer, SQLite-backed sync engines—less server, more client. |

| Go is still not good |
| |
| |
| Go’s been catching flak for years, and the hits keep coming: stiff variable scoping, no destructor patterns, clunky error handling, and brittle build directives. Critics point out how Go’s design often blocks best practices like RAII and makes devs contort logic just to clean up resources or manage state. |

| Developer's block |
| |
| |
Overdoing “best practices” can kill momentum. Think endless tests, wall-to-wall docs, airtight CI, and coding rules rigid enough to snap. Sounds responsible—until it slows dev to a crawl.
The piece argues for flipping that script. Start scrappy. Build fast. Save the polish for later. It’s how you dodge dev paralysis and keep ideas flowing. |

| Bash Explained: How the Most Popular Linux Shell Works |
| |
| |
Bash isn't going anywhere. It's still the glue for CI/CD, cron jobs, and whatever janky monitoring stack someone duct-taped together at 2am. If automation runs the show, Bash is probably in the pit orchestra.
It keeps things moving on Linux, old-school macOS (think pre-Catalina), and even WSL. Still oddly cross-platform. Still everywhere. |
