Today we are going to examine methods for calculating z-scores for our data in the database. We want to do this transformation because, when we carry out logistic regression we want to be able to compare the effects of the different factors on fire probability.
Today you don’t need a reason for choosing Postgres, if you do all your answers are above. Today the question has really shifted to what are you not using Postgres for, and how can the community better support that happening natively in Postgres in the future.
This week Apple started delivering Macs using their own Apple Silicon chips, starting with a Mac SOC named the M1. M1 uses the ARM instruction set and claims some amazing acceleration for media workloads. I wanted to know how it would do running PostgreSQL, an app that's been running on various ARM systems for years. The results are great!
Open source developers sometimes have a hard time figuring out what feature to focus on to generate the greatest value for end users. As a result, they will often default to performance. Performance is the one feature that every user approves of. The software will keep on doing all the same cool stuff, only faster.
In this blog post, we'll discuss how to set up streaming replication in Windows. Credit goes to my colleague Douglas Hunley whose blog post on setting up streaming replication on Linux served as inspiration.
We're putting together an awesome PostGIS Day virtual conference on Thursday, Nov 19th. Last year we hosted our first PostGIS Day in-person in St. Louis and although we can't gather in the same way this year, going virtual allows us to give even more talks!
Apple's Intel-based laptops are very popular among developers, and that's as true of people who work on PostgreSQL as other groups. Tomorrow, the first shipping Apple laptops running on ARM CPUs instead of Intel are expected.
I was sent a link to a tweet regarding election night forecasting and of course the default questions was... could be run under PL/R inside Postgres. Like about everything else at Crunchy Data we believe all things are better with Postgres.
As a database grows and scales up from a proof of concept to a full-fledged production instance, there are always a variety of growing pains that database administrators and systems administrators will run into.
When should you be alerted about issues in your PostgreSQL clusters? How do you troubleshoot them? What are some typical solutions?
What are some PostgreSQL monitoring stats that are typically used to monitor the health of your databases?
What are some of the key stats to look at to ensure your PostgreSQL cluster is healthy? How can you use this stats to diagnose the problem?
PostgreSQL 13 was released last week. I'm excited about this one, as the more mature partitioning plus logical replication features allow some long-requested deployment architectures
PG Routing is a powerful routing tool, usually used for pathfinding/mapping/direction applications. Today we’re going to use Postgres via Crunchy Bridge to find the most influential Yacht Rock artist, and find out why it’s Michael McDonald.
