It works on any JavaScript runtime.

]]> Docker Best Practices /en/posts/docker-best-practices/ Sat, 28 Mar 2026 10:00:00 +0800 simi@simi.studio (Simi) /en/posts/docker-best-practices/ Current version is Docker 29.4. Docker Desktop is the recommended approach for macOS.

]]> Docker Compose Best Practices /en/posts/docker-compose-best-practices-v2/ Sat, 28 Mar 2026 10:00:00 +0800 simi@simi.studio (Simi) /en/posts/docker-compose-best-practices-v2/ Docker Compose does one thing well: it describes a multi-container environment and lets a laptop, a CI runner, and another machine start the same stack.

]]> Redis Best Practices /en/posts/redis-best-practices/ Sat, 28 Mar 2026 10:00:00 +0800 simi@simi.studio (Simi) /en/posts/redis-best-practices/ Current version is Redis 8.6.2.

]]> PostgreSQL Best Practices /en/posts/postgresql-best-practices/ Thu, 05 Mar 2026 10:00:00 +0800 simi@simi.studio (Simi) /en/posts/postgresql-best-practices/ Current version is PostgreSQL 18.3. Queries, indexes, partitions, and JSONB belong in the official docs. Install commands are just the door.

]]> Flask Best Practices /en/posts/flask-best-practices/ Wed, 25 Feb 2026 10:00:00 +0800 simi@simi.studio (Simi) /en/posts/flask-best-practices/ Flask 3.1.x remains one of the best choices for teams that want Python’s ergonomics without surrendering architectural control. Its minimal core is a strength, not a shortcut: the boundaries, dependencies, and operational model are chosen instead of inheriting a large framework’s opinions.

That flexibility also means poor habits scale badly. A Flask codebase can stay small, readable, and fast for years—or gradually turn into a pile of global state, implicit coupling, and fragile request handlers.

This note focuses on production-grade Flask 3.1.x practices for teams building maintainable services and web applications.

]]> Redis 7 New Features /en/posts/redis-7-new-features/ Mon, 22 Dec 2025 09:38:00 +0800 simi@simi.studio (Simi) /en/posts/redis-7-new-features/

Note: Redis 8.0 reached GA in 2025, adding native vector search and more. Redis 7 features only; Redis 8 upgrade is a separate topic.

Redis 7 is more than a version bump—it unifies search, JSON support, and graph databases into one coherent platform. Key changes and when to use what follow.

]]> PostgreSQL Performance Optimization /en/posts/postgresql-performance-optimization/ Sat, 20 Dec 2025 21:13:00 +0800 simi@simi.studio (Simi) /en/posts/postgresql-performance-optimization/ Slow SQL shows up in the plan first, not in postgresql.conf. Follow PostgreSQL: run EXPLAIN (ANALYZE, BUFFERS), see Seq Scan versus Index Scan, then choose an index, a rewrite, or a knob.

Missing indexes, a function wrapped around a column, stale statistics, autovacuum falling behind, cost constants left on the spinning-disk default — any of those send the same query through a full table. Read the plan before editing config.

]]> Prometheus + Grafana Monitoring: Making LLM Services Visible /en/posts/prometheus-grafana-monitoring/ Fri, 19 Dec 2025 20:21:00 +0800 simi@simi.studio (Simi) /en/posts/prometheus-grafana-monitoring/ An LLM process that “looks fine” on CPU is often already serving a worse model, a slower first token, or a truncated completion. Prometheus + Grafana will show requests; a default node dashboard will not show tokens, TTFT, or a model label exploding cardinality.

The path is scrape → query → rules → panels. Every llm_* name below is an example metric name, not a standard export from Prometheus or from any particular gateway. Match /metrics before copying queries.

]]> Python Best Practices /en/posts/python-best-practices/ Wed, 15 Oct 2025 10:00:00 +0800 simi@simi.studio (Simi) /en/posts/python-best-practices/ Production Python locks the interpreter and pyproject.toml before talking about asyncio or speed. Types, tests, and a lockfile are the default, not extras. No “faster” or “production-grade” without a measured comparison.
