PostgreSQL 10: What to Look ForAmit Langote PostgreSQL 10 will include several new features and improvements, including logical replication which allows replicating specific tables, quorum-based synchronous replication, improved partitioning support, pushing more computations to foreign databases with FDWs, expanded parallel query capabilities, techniques to reduce write amplification, indirect indexes, executor and statistics overhauls, and easier backup/replication configuration defaults. Many of these features are still in development.

• A transmission media in data communication is a physical path between the sender and
the receiver and it is the channel through which data can be sent from one location to
another. Data can be represented through signals by computers and other sorts of
telecommunication devices. These are transmitted from one device to another in the
form of electromagnetic signals. These Electromagnetic signals can move from one
sender to another receiver through a vacuum, air, or other transmission media.

wAIred_RabobankIgniteSession_12062025.pptxSimonedeGijt In today's world, artificial intelligence (AI) is transforming the way we learn.
This talk will explore how we can use AI tools to enhance our learning experiences, by looking at some (recent) research that has been done on the matter.
But as we embrace these new technologies, we must also ask ourselves:
Are we becoming less capable of thinking for ourselves?
Do these tools make us smarter, or do they risk dulling our critical thinking skills?
This talk will encourage us to think critically about the role of AI in our education. Together, we will discover how to use AI to support our learning journey while still developing our ability to think critically.
