Pulling a big result set from Snowflake into Tableau isn't network-bound. It's CPU-bound — burning cycles converting columns to rows and straight back to columns. @ian.columnar.tech of Columnar on ADBC, and the 10-100x you get by deleting that step. link below

Traditional databases were "sold on the golf course" — to purchasing departments, not developers. @hannes.muehleisen.org on how that blind spot created the gap between pandas and Spark that @duckdb.org walked right into. Episode link below

"Never bait and switch developers." @jt.lol watched CRDTs promise magic on day one and deliver misery by month six. Convex starts with serializable transactions and typed, reactive code instead - and it turns out that's what AI agents write best too. episode link below

Software has solved "it works on my machine," but data pipelines are still the Wild West. 🤠 Hussain (xorq) breaks down why the research-to-prod gap persists, why Feature Stores struggled, and how applying "lock files" to data can finally fix reproducibility. link below

“Parquet is great… until GPUs, multimodal data & million-column schemas show up.” The creator of pandas/Arrow @wesmckinney.com digs into Arrow vs Parquet, new columnar + table formats, DataFusion/DuckDB, metadata headaches, and what AI coding agents mean for open source infra. Episode link below

New episode: chatting with bauplan founders Jacopo Tagliabue and Ciro Greco on shipping AI with real-world data constraints. Why listen 1. Data pipelines determine model effectiveness, far more than most teams admit.

What if email isn’t an inbox—it’s your company’s knowledge graph? 🧠 @thatguybg.bsky.social breaks down: acquisition reality (retention/culture > price), startup energy vs. big-co burnout, Launch House, and Micro’s AI layer that turns mail into CRM/hiring/sales apps + proactive updates” link below

1/5. @paradedb.bsky.social has raised a $12M Series A to bring Elasticsearch workloads to Postgres. 🧵

1/12. I'm excited to share our latest technical blog post on ParadeDB. After a brief hiatus focused on transforming ParadeDB into an enterprise-ready database, expect to hear a lot more from us. Today's post: How ParadeDB built an LSM on top of Postgres block storage. 🧵

Zero-ETL search and analytics for Postgres

paradedb.com

Really fun chatting with @philippemnoel.bsky.social about how to turn Postgres into a full search and analytics engine. The extensibility of Postgres is one of its most brilliant design choices, and ParadeDB's extensions on top of that bring impressive capabilities.

Tech on the Rocks@totrrocks.bsky.social · 2y ago

New episode! We talked with Philippe Noël about building ParadeDB, an exciting Elasticsearch alternative built on Postgres that offers fast full-text search and analytics with zero ETL. Search is becoming the primary interface for data-heavy applications - and AI.

So much fun chatting with David of Arcjet about security tooling, while "security as code" matters, AI's role in tackling bots, and everything in between. David is also the creator of Console.dev the best dev tools newsletter out there. Have a listen this is a great one.

Tech on the Rocks@totrrocks.bsky.social · 2y ago

Join us at another episode of Tech on the Rocks, this time with @davidmytton.social of Arcjet. We talk about security as code, security in a world of AI and dev tooling. Check the episode here: https://buff.ly/4ggWGeO
