Ask HN: What's your "it's not stupid if it works" story?

Hacker News Discussion ↗

Engineers and tinkerers share dozens of “it’s not stupid if it works” stories, from production systems built on SQLite, headless browsers and mmap’d SSDs to hacked-together plumbing, heating, and car repairs. Across wildly different domains, the anecdotes highlight a recurring theme: quick, ugly solutions often outperform “proper” architectures for years, revealing how constraints, deadlines, and real-world reliability frequently trump elegance. Many also note the downside — these stopgaps tend to become permanent infrastructure and technical debt once they prove themselves in the wild.

Infrastructure & DevOps Workarounds

  • Many stories revolve around “just restart it”: cron jobs or scripts that periodically reboot Pis, restart flaky services, or bounce databases until a bad table can be dropped.
  • Memory leaks and structural crashes are often “solved” by regular restarts, failovers, or scheduled bounces instead of root-cause fixes; some argue this is effectively standard DevOps practice, others see it as dangerous tech debt.
  • People bypass complex deployment stacks with simple tools: envsubst or sed for templating, single giant serverless functions with while loops for robustness, or using OpenResty/Lua hardcoded auth.
  • VPNs and firewalls get sidestepped via sshuttle, HAProxy port-forward tricks, or scripts that reboot consumer routers to rotate IPs.

Home, Hardware, and Physical Hacks

  • Numerous “keep it alive” hardware stories: Arduino/ESP32 relays to auto power-cycle boilers, freezer tricks to revive failing electronics, magnets or heating/boiling to resurrect drives and CDs.
  • Mechanical bodges: servo-geared thermostats, coins or frozen sausages as heatsinks, oscillating CD trays or mouse movements to prevent screen blanking, sanded fans jammed into tight PC cases.
  • Plumbing and household hacks include air compressors or improvised tools to blast clogs, toilet tanks as plant watering reservoirs, and ad‑hoc CPAP or humidifier mods.

Web, Enterprise, and Legacy Integration

  • Heavy use of browser automation and screen-scraping (Watir, Selenium, Capybara, AutoHotKey) to integrate with ancient CRMs, IE6-only vendor sites, and green‑screen mainframe systems.
  • Creative abuse of Google Sheets, Outlook, Access, Lotus Notes, and Word via macros/COM to build shadow systems when proper APIs or integration servers are unavailable.
  • PDF and image generation frequently delegated to headless browsers (Chrome, Firefox) because purpose-built converters are unreliable or inconsistent.

Data, Storage, and IPC Hacks

  • SQLite appears everywhere: as an IPC mechanism, lightweight server DB, or even coordination layer; many report it scales far beyond expectations for their workloads.
  • Some systems mmap entire SSDs into a single C++ struct or flat file, deliberately skipping filesystems and databases to gain huge speed, with acknowledged fragility and recovery risks.
  • Others hardcode massive arrays (e.g., 100k coupon codes) or treat text files under version control as “databases,” with surprisingly acceptable performance.

Security, Anti-Abuse, and Policy Games

  • “Not really security” measures are used to placate scanners or business needs: CSP upgrade-insecure-requests just to improve grades, or hidden JavaScript/time-delayed form fields to deter spam instead of CAPTCHAs.
  • Homegrown WAFs and request filters in front of WordPress and other apps successfully block years of attacks, sometimes effectively reinventing commercial products.
  • Participants note the tension between clever hacks and long-term maintainability, but the thread overall celebrates pragmatic solutions that keep systems—and businesses—running.
