I’ve been at OpenAI for almost a year now. In that time, I’ve trained a lot of generative models. More than anyone really has any right to train. As I’ve spent these hours observing the effects of tweaking various model configurations and h

In this technical deep dive, we take a look at the columnar engine that delivers industry leading query performance for AlloyDB for PostgreSQL.
A misconception that I held for a really long time was that systems that use SQL (Structured Query Language) are by definition relational databases, and systems that don’t (e.g., MongoDB, Cassandra) are non-relational. It’s easy to understand whether a database uses SQL or not, but what does it mean when we say a…
When a +10% isn’t really a +10% OK, this is an infuriating startup experience: You ship an experiment that’s +10% in your conversion funnel. Then your revenue/installs/whatever goes up by +10% right?
PostgreSQL isn’t just a simple relational database; it’s a data management framework with the potential to engulf the entire database realm. The trend of “Using Postgres for Everything” is no longer limited to a few elite teams but is becoming a mainstream best practice.

How we built an authorization system based on Google Zanzibar
Dealing with real-world data is hard. You often end up stuck between the document model of JSON and the relational model of SQL databases. There's a better way. It's called super-structured data.
Optimize your Django SQLite configuration for production.
Learn how queues make horizontal scaling, scheduling, and flow control easier in cloud systems, and how to make them durable and observable.
An example of how you can encrypt Postgres data at rest using PGO, the open source Postgres Operator from Crunchy Data using AWS EBS gp2 volumes.
Citus gives you all the greatness of Postgres plus the superpowers of distributed tables. By distributing your data and queries, your application gets high performance—at any scale. The Citus database is available as open source and as a managed service on Azure.

How and why marimo represents notebooks as dataflow graphs
Recently, a Facebook dataset was released consisting of the complete set of users from the Facebook networks at 100 American institutions, and all of the in-network “friendship” links between those…
Let’s talk about the stream. The SoundCloud stream represents stuff that’s relevant to you primarily via your social graph, arranged in time order, newest-first. The atom of that data model, an event, is a simple enough thing. Timestamp User who did the thing Identifier of the thing that was done For example, At…

As a researcher/engineer (really, an algorithm developer) in the general area of audio and speech processing, I've always run into the same difficulty at all the companies I've worked at: How to quickly prototype and develop algorithms, and subsequently turn them into efficient code that can be deployed to customers.
In June 2016 Ravi Mody and Tim Schmeier gave a presentation at the NYC Machine Learning meetup to discuss their work on the data science…
There are data sources out there, but which data source you choose depends on which technology you wish to get experience working with. The experience should be of the technologies you are using, rather than what the data is. Certain datasets pair better with certain technologies. Simulating the data can be another…
We are excited to announce the next phase of the OpenTelemetry Protocol with Apache Arrow project (OTel-Arrow). We began this project several years ago with the goal of bridging between OpenTelemetry data and the Apache Arrow ecosystem. Apache Arrow is a framework designed for zero-copy exchange of structured data…
A while ago a friend of mine asked me how I would go about building a ‘People Who Like This Also Like …’ feature for a music startup he was working at. For each band or musician, he wanted to display a list of other artists that people might also be interested in.
