Reliability > Shipping speed. Fight me.
https://www.reddit.com/r/programming/comments/1qgxl7w/reliability_shipping_speed_fight_me/

<!-- SC_OFF -->Building a Yahoo Finance MCP server. Day 3: 17 timeouts in 20 requests. Most devs would ship anyway and call it "MVP." I spent 2 weeks engineering resilience instead. Here's what I built: 🔹 Circuit breaker — CLOSED/OPEN/HALF_OPEN states with auto recovery 🔹 Token bucket + adaptive + per-endpoint rate limiting 🔹 LRU cache with stale-while-revalidate — 70-90% hit ratio 🔹 Data quality scoring — Completeness + integrity validation 🔹 Chaos tests — Network failures, rate limits, partial data PM decision: Don't ship unreliable code. Your 2-day ship time doesn't matter if your bot dies at 2 AM. Built with AI as my pair programmer (TRAE 😍). TRAE caught edge cases I'd miss. We debated tradeoffs. We wrote chaos tests together. The results: ✅ 95%+ test coverage ✅ ✅ 13+ tools verified working ✅ Production-grade resilience Known issues: - Crypto/forex = placeholder data - Financials = may fail for some symbols The hard truth: Building on unreliable APIs? Either engineer resilience or inherit their unreliability. tl;dr: Chose 2 weeks of resilience over 2-day ship time. PM decision was reliability > speed. AI pair programmer helped. 95% test coverage. <!-- SC_ON --> submitted by /u/kanishkanmd (https://www.reddit.com/user/kanishkanmd)

The hidden cost of PostgreSQL arrays
https://www.reddit.com/r/programming/comments/1qh13xf/the_hidden_cost_of_postgresql_arrays/

<!-- SC_OFF -->Very thoughtful piece on the tradeoffs of Postgres ARRAYs that in many case can replace one-to-many & many-to-many relationships: Wait? Are we going to talk about JSONB arrays? Not at all. The whole concept of arrays in RDBMSs is actually document storage in disguise. In database design, locality ensures faster retrieval times by keeping related data close on physical storage.Whether you use a distinct integer[] type or a JSON list [1, 2, 3], you are making the exact same architectural decision: you are prioritising locality over normalisation. <!-- SC_ON --> submitted by /u/BinaryIgor (https://www.reddit.com/user/BinaryIgor)

Fluxly - A lightweight, self-contained DAG workflow framework (decoupled from orchestration)
https://www.reddit.com/r/programming/comments/1qhikgp/fluxly_a_lightweight_selfcontained_dag_workflow/

<!-- SC_OFF -->Hi everyone, I wanted to share Fluxly, a framework I built for running portable, self-contained DAG workflows, inspired by architectural patterns I worked with at Mobileye. Core idea:
Each workflow is a standalone execution endpoint - structured, typed, and runnable without being coupled to any orchestrator. GitHub:
https://github.com/ShaharBand/fluxly --- 🚀 What Fluxly is Fluxly lets you define DAG-based workflows where: Each workflow runs as a single self-contained unit It can be triggered via CLI, API, or environment variables It can be packaged into a Docker image Any external scheduler (Airflow, Argo, CI/CD, cron, etc.) can trigger it without glue code The workflow owns its logic, validation, retries, and structure - orchestration is optional and external. --- ❓ Why I built it (the problem it tries to solve) From experience, many containerized pipelines end up as: Ad-hoc scripts scattered across containers Inconsistent inputs/outputs Retry, timeout, and logging logic duplicated or forgotten Tight coupling to a specific orchestrator SDK On the other hand: Heavy orchestrators (Airflow, etc.) introduce operational overhead when all you want is a portable job Orchestrator-coupled SDKs assume persistent backends and remote control planes, which don’t fit fire-and-forget workloads Fluxly keeps the workflow clean and isolated: Explicit DAG Typed I/O models Uniform entrypoints (CLI / API / env) Clear node boundaries No hidden runtime coupling It works especially well when: Each Docker image should be simple and autonomous You want structure without infrastructure overhead You want the same workflow to run locally, in CI, or under any scheduler In monorepos (or via thin wrappers), Fluxly can also standardize validation, logging, metadata, and interfaces across many pipelines. --- ✨ Key features DAG-based workflows with explicit dependencies Auto-generated CLI commands and FastAPI endpoints per workflow Strict validation using Pydantic models Nodes manage their own execution and retries Local-first development, production-ready execution Easy to extend with logging, metrics, or org-specific wrappers --- 🛠️ Stack Python, Pydantic, Typer, FastAPI, Uvicorn, Loguru, Diagrams, Pixi, Ruff, Mypy, Pytest, MkDocs --- 📦 Install pip install fluxly --- 🙏 Feedback welcome
I’d love feedback and Happy to answer questions or discuss tradeoffs. <!-- SC_ON --> submitted by /u/ShaharBand (https://www.reddit.com/user/ShaharBand)
