The author describes evolving syntax highlighting on their Eleventy site, starting from the default PrismJS plugin to a custom server-side hack for line numbers. They then detail integrating MicroLighter, a client-side web component, by leveraging Eleventy's bundler for conditional loading and managing content escaping for optimal performance.
Codename One introduced an experimental native Java backend that compiles Java controllers to a tiny native executable via ParparVM. Benchmarks show sub‑millisecond startup, 10‑40 MiB memory, and up to 20 % higher request throughput than a Go fasthttp server.
Server‑only code can silently inflate client bundles in Next.js 15+ apps. The article shows how to spot leaks with @next/bundle-analyzer, prevent them by removing shared barrel files or adding the `server-only` guard, and enforce a deny‑list of server modules via a custom ESLint rule that scans the AST of files with a `'use client'` directive. The rule is wired into a CI bundle‑budget check using…
TanStack Charts α is a framework‑agnostic, TypeScript‑first charting library that implements a grammar‑of‑graphics API (marks, scales, channels, transforms, layers). It ships as a single npm package with adapters for React, Preact, Vue, Solid, Svelte, Angular, Lit, and vanilla DOM, and can run on server or client. The runtime is headless; type inference stays tied to the source row, so each mark…
pgAssistant 3.8.0 expands from a tuning advisor to a continuous PostgreSQL improvement platform, adding a Collector that records historical workload and environment data. It lets teams run an Observe‑Diagnose‑Prioritize‑Plan‑Implement‑Measure loop, compare consecutive snapshots, and measure the impact of applied recommendations.
ParparVM’s HashMap suffered catastrophic miss latency due to linear probing on dense integer keys. By adopting CPython‑style perturbed probing (Swiss‑table style) and extending tagged immediate values to more primitives, miss latency dropped from 32 s to ~45 ms, allocation pressure fell dramatically, and overall performance stayed roughly flat despite a modest hit‑time slowdown.
A hands‑on benchmark of five LLM code‑review models (Claude Opus 5, GPT 5‑6 Sol, Grok 4.6, Kimi 3, GLM 5.3, Qwen 3.8 Max, DeepSeek v4 Pro) shows that all models ace tiny 15‑line diffs but diverge sharply on 100‑300‑line, cross‑file changes. The author built a deterministic harness (single HTTP call, fixed system prompt, JSON output) and measured detection rate, false‑positives, latency, token usa…
