#LabPlot (upcoming release) just got even more powerful.
The latest merge request introduces native support for importing data from the following file formats:
👉 #Apache #Parquet
👉 #Apache #ORC
👉 #Arrow #IPC (#Feather)
—three of the most efficient and widely used columnar storage formats in data science.

🚀 New Blosc blog post: one selective query, 24.3M taxi trips, five tools.
⚡ Cold cache: CTable/.b2z beats DuckDB by ~1.9x (and pandas by 9.4x)
🎯 Block-level indexes prune ~90% of the data — never read, never decompressed
🤝 Warm cache: dead heat with DuckDB
💾 All for just a 2% storage premium over Parquet
🐍 Results are NumPy arrays, no conversion tax

When does #Iceberg beat #Parquet+projection on #AWSGlue, and when doesn't ?
An end-to-end #ETL PoC on #AWS to find out: producer, #Kinesis, two #Firehose paths, two #Glue jobs, #Athena.
🔮 Spoiler: how the data is read is the key to the choice.
In the article: every choice with its why, plus a few gems from some Glue experience 😄

A Cross-Country and Cross-Wikipedia Comparison We compare the number of biographies by birth year and country against demographic birth data to estimate the probability of appearing in different Wikipedia language editions, depending on one's country of birth. Research Questions What is the probability of having a biography in different Wikipedia language editions? Does country of birth affect this probability? If so, which birth countries are most overrepresented on Wikipedia? Do different Wikipedia editio
