Regex vs. LLM for B2B document extraction. This week, I tried out both.

:blobcoffee: The rule-based pipeline with pytesseract + regex worked perfectly for Layout A. For Layout B? Every single field returned None.

:blobcoffee: Because "PO Number" and "Order Reference" are the same thing for a human. Not for a regex pattern.

:blobcoffee: The LLM-based approach (pytesseract + Ollama + LLaMA 3) extracted both layouts correctly, without touching a single rule. It even normalized the date format automatically.

:blobcoffee: But LLMs aren't always the right answer. If your documents are stable, speed matters at scale, or explainability is required, regex might still win.

The "algorithmic ultimatum" has arrived. Prediction markets just pushed "Power Plants Day"—the total neutralization of the Iranian electrical grid—to a 94% probability for Friday, May 15. When the "smart money" hits this level of certainty, we aren't looking at a guess; we're looking at a countdown.

🌑 Astrobites (M. Ogborn, Penn State): wandering supermassive black holes can be revealed via tidal disruption events (TDEs) – stars ripped apart by an SMBH. The event AT2024tvd lies ~0.8 kpc off the host galaxy's nucleus – the SMBH likely drifted away. Future key tool: Rubin/LSST.

💧 Interstellar comet 3I/ATLAS carries water from another planetary system: the ALMA radio interferometer measured ~30× more semi-heavy water (HDO) than Solar System comets and ~40× more than Earth's oceans. It formed in extreme cold below 30 K. Published in Nature Astronomy.

☀️ A University of Sheffield team (R. Jain) has published in Solar Physics: an AI decodes the Sun's p-modes – acoustic waves carrying info from deep inside our star. 30 years of helioseismic data + machine learning = an independent forecaster of solar activity, key to protecting satellites & power grids.

🔭 Citizen scientists from Backyard Worlds: Planet 9 have DOUBLED the known population of brown dwarfs! A new paper (Schneider et al., Astronomical Journal) reports 3,000+ motion-confirmed L & T dwarf candidates found by volunteers in WISE/NEOWISE-R data via Zooniverse — over the project's 10 years.
