Reposted by Dylan PieperAlejandro Wainzinger @xevix.bsky.social · 15/08/2025Stretching DuckDB w/ Common Crawl, ~1.7B rows, ~300 parquet files. ~2-3s for single-column aggregations, ~2-3 mins to SUMMARIZE the data, peaking at ~12-14GB memory usage. Not exactly real-time, but the fact you can do this on a laptop with no server setups or Spark pipelines is still amazing. 1439

Reposted by Dylan PieperHadley Wickham @hadley.nz · 18/06/2025New to me is the term "premature closure", where you too quickly latch on to the first solution you see. Always a danger in coding, but particularly so today when LLMs can give you a plausible fix so so quickly. www.shayon.dev/post/2025/16...shayon.devPitfalls of premature closure with LLM assisted codingWhen LLM models generates clean, professional-looking code, it's tempting to stop exploring alternatives. But therein lies the risks that comes with premature closure. So what is premature closure? 79614
