Madrid ↔️ Lisbon in just 3 hours – we're on board 🚄
Today, we adopted a plan to complete the Madrid–Lisbon high-speed rail connection by 2034.
This is a key step in fully integrating Portugal and Spain into the European high-speed rail network.

So, we now have:
- BigQuery
- ClickHouse
- Databricks
- DuckDB
- Exasol
- H2
- Snowflake
- Teradata (the inventor, I think?)
And now also:
- Oracle!
I'm assuming MySQL will follow suit, soon? PostgreSQL, when!?

Apply the Oct 2025 Release Update and Oracle Database 23ai becomes Oracle AI Database 26ai
This adds the QUALIFY clause
QUALIFY filters window functions after grouping
Like the HAVING clause does for aggregate functions
SELECT ... FROM ...
QUALIFY fn OVER ( ... ) > ...

I think one of the saddest things about being a millennial is remembering a time when technology was advancing in a way that made life better and easier and more exciting instead of actively, intentionally worse

Poisoning attacks require a near-constant number of documents regardless of model size. In our experimental setup with models up to 13B parameters, just 250 malicious documents were sufficient to successfully backdoor models.

Cars, bridges and houses are constantly battered by the elements, Software is made out of bits, that do not degrade. It stays the same. So why does software require so much more maintenance than cars, bridges and houses?
