At university, there was a maxim that, you could only do 2 of these 3:
study, sleep, party.
As a dad, I experience that I can only ever focus on 2 out of these 3 at any given point in time:
career, good parent, regular exercise.
Is it just me?
study, sleep, party.

This is very cool. Lex and Aleksey show you how you can use an #LLM #assistant to generate code that automatically imports features into the Hopsworks feature store. This makes getting started with the #ai #lakehouse even easier! See youtu.be/wtEPONdKV6Y for another great episode of #showdonttell.

What tables in the Data Warehouse should be exposed to data scientists to create features from?
The gold layer is aggregated features. If you want to create your own aggregations, you need access to the raw events (bronze or silver layers).

There is a concerted effort to drive a wedge between Europe and the US by the new US Administration.
Apparently we should not be worried about Russia/Ukraine, but free speech and Greta are our big problems. I don't see Europe taking this lying down.

Tesla's proprietary charging infrastructure is now their weak point in Sweden. Massive queues. Unions have stymied rolling out Tesla charging stations. Commodity charging is fine.

Good reproducible benchmark study by @coiled.io. I get this question all the time by MLOps folks. What size of workloads can frameworks handle :
* Pandas ~1 GB (this one i added for reference, not in the study)
* Polars ~10 GB
* DuckDB ~100GB to 1TB
* Dask and PySpark up to 10 TB

They are like s3 buckets, but you write iceberg tables. They will do maintenance for you, make it available in AWS Glue for querying via Athena, etc. $26.5/TB/month for s3 tables. That's cheap.
