• Hacker News1I run multiple $10K MRR companies on a $20/month tech stackThe author argues that entrepreneurs can build successful businesses without venture capital by running extremely lean operations. They advocate using cheap VPS servers instead of AWS, Go programming language for efficiency, local AI hardware to avoid API costs, SQLite databases, and simple tools like GitHub Copilot to keep monthly costs under $20 while maintaining scalability and performance.SQLite vs PostgreSQL performance and features:Debate over whether SQLite or PostgreSQL is better for single-machine deployments. SQLite advocates highlight its raw speed and simplicity, while PostgreSQL supporters emphasize features like concurrent writes, easier scaling, and operational benefits like remote access and backups.Simple VPS vs cloud complexity:Discussion about over-engineering with Kubernetes, serverless, and multi-zone setups when simple VPS hosting would suffice. Many share examples of unnecessarily complex deployments for small user bases, with some defending that basic infrastructure knowledge has been lost.Cost optimization strategies:Debate over spending $5 vs $20+ monthly on hosting. Some argue the extra $15 is negligible for business value, while others advocate for learning resource constraints and avoiding premature optimization through artificial limitations.
• Reddit science1Using scented products indoors changes the chemistry of the air, producing as much air pollution as car exhaust does outside, according to a new study. Researchers say that breathing in these nanosized particles could have serious health implications.Using scented products indoors, such as flame-free candles and wax melts, can create significant indoor air pollution comparable to car exhaust. Research by Purdue University found these products release nanosized particles that can penetrate deep into lungs and potentially enter the bloodstream, posing serious respiratory health risks.Misleading title scope:Discussion about how study only focused on wax melts but title suggests all scented products, with debate about whether findings could logically extend to other scented itemsHealth concerns from chemist:A chemist's perspective against using scented products leads to sharing of personal health impact stories, from COPD to cancer cases, and debate about necessity of artificial scentsAir purification solutions:Discussion of HEPA filters and other air purification methods as solutions, with debate about effectiveness against different types of pollutants like VOCs and nanoparticles
