Accurate ⚡ electricity consumption forecasts require up-to-date 🌡️ weather ☁️ forecasts. a-Gnostics provides forecasts for Europe and North America with a focus on key energy markets.
Migrating to Tower didn’t just streamline their infrastructure, it gave them a competitive edge.

Our first talk tonight is from @datancoff.ee on How to prepare your AI Agents for the Ice(berg) Age.

LLMs are extremely powerful, but their data is often old and they hallucinate. We can largely solve that using agents with tools.

Forgive me, Data Father, I have sinned. We at Tower created an orchestrator that is not a data flow and not a DAG. It has:
- a way to run apps
- a way to wait for runs to finish
- a scheduler

That's it

You can't solve world hunger with it, but everything else you can

🚨 New Features Monday!

1️⃣ Support for Iceberg Catalogs inside Tower apps
2️⃣ Tower SDK with Tower Tables, probably the simplest way to read and write to Iceberg tables from Python code

“pip install tower” installs both the Tower CLI and the SDK including Tables.

A few weeks ago, we demoed Tower.dev at the AI Launchpad stage of the Data Council. Several dozen prospect conversations later, I finally had the time to post some pictures and the most memorable moments from that week.

The ducks have done it again. Kudos to the @motherduck.com team for building a local UI for DuckDB:

1️⃣ Use this UI on your laptop to run SQL queries on Iceberg tables in S3
2️⃣ Get closer to the multi-engine, shared storage nirvana
3️⃣ Set-up time of ⌚ 32 minutes, door-to-door

Teaching 5 teammates how to fish is better than owning 5 fishing rods. It's true for fishermen. It's also true for data engineers.

Tower.dev's Teams let your teammates self-serve their change requests, while you get back time to work on strategic projects

Yes, but, one is what appears to be a 50 yard rifle shot pose wheareas the other one is a 10 yard pistol shooting pose.

AI coding assistants like Cursor are not the 10x productivity boosters for data engineers and not their replacements, as some talking heads claim. But they can be 10x multipliers for another group of folks - the 😎 customers of 👷 data engineers! tower.dev/blog/ai-auto...

How do you run 🐍 Python data apps on Iceberg open tables without going bonkers settings up infrastructure ⁉️

That's how:
1️⃣ Sign up for Tower.dev
2️⃣ Take your Python script and turn it into a Tower app
3️⃣ Run this app on Tower

Final post of my series on how to build an open, multi-engine lakehouse using Python-only tools is out.

Learn how to use 🐻‍❄️Polars to query an open lakehouse, enabled by a managed 🛏️REST Iceberg catalog.

Today's Hamlets, Princes of Denmark, ask the question differently: "To use or Not to use Snowflake Open Catalog as managed Iceberg catalog?"

I summoned the inner Shakespeare and penned an answer. Lemme know what you think. Or not.

Can Python compete with DuckDB and Spark as the "query engine" for Iceberg-based lakehouses? Wrote a little piece that begins to answer that Q
