Members of the public can search a newly released database of 1,600 stars to find signs of undiscovered exoplanets. The dataset, taken over two decades by the W.M. Keck Observatory in Hawaii, comes with an open-source software package and an online tutorial.
Introducing the $5 PlanetScale plan.
Results and speed for other programs on enwik8 and enwik9 are available at the Large Text Compression Benchmark .
I show toy implementations of Python decorator patterns that may be useful for Data Scientists.
We developed an NLP deep learning model using a one-dimensional convolutional neural network to predict future stock market performance of companies using Azure ML Workbench and Keras with open source for you to replicate.
Meltano is an open source tool for the entire data science lifecycle, and we want your contributions and feature requests!
How we implemented fair queueing strategies for Postgres-backed task queues to ensure fair execution time across tenants.
Key learnings about how to get the best performance from GCP, AWS, and Azure based on original research and conversations with the big three.

Craig takes a look at the history of Postgres. From the origins of the project through some of the key production features that make Postgres what it is today.
ORM looks great early in a project but breaks down as complexity grows, forcing you to learn SQL anyway. Relations aren't objects. Either use NoSQL for object-like data or write a model layer with real SQL. ORM's abstraction is leaky, its efficiency poor, and the alternatives are better.
Edit: This article is firmly out of date now. I have not gone back to try dynamoDB but I have heard they have changed how throughput is…
Why every database will become a vector database, sooner or later
I've been using SQLite in several production projects for six months, and I've encountered some surprising aspects.
Keeping workflow state and application data in the same Postgres database lets one transaction update both, simplifying idempotency and atomicity.
Confluent is building the foundational platform for data in motion so any organization can innovate and win in a digital-first world.
Faster JSON handling in a relational database.
By PATRICK RILEY For a number of years, I led the data science team for Google Search logs. We were often asked to make sense of confusin...
E ver since I released rayshader to the public, there’s been one question that comes up time and time again: “How do I use rayshader to overlay satellite imagery onto a 3D surface?” And I can see why: 3D maps with real satellite images are super cool, and there are few detailed tutorials out there on how it’s done in…
Based on your feedback, we've improved the Automatic Data Conversion settings, and made them also available in Excel for Mac.
Discover Sparse Llama: A 50% pruned, GPU-optimized Llama 3.1 model with 2:4 sparsity, enabling faster, cost-effective inference without sacrificing accuracy.
MongoDB is a long-time user of Jepsen . Over the past three years, Jepsen has performed several analyses for MongoDB, and MongoDB has integrated an expansive Jepsen test suite into their CI system. In March, MongoDB requested Jepsen perform an analysis on a previously untested configuration: sharded clusters. We also…

RabbitMQ is a distributed message queue, and is probably the most popular open-source implementation of the AMQP messaging protocol. It supports a wealth of durability, routing, and fanout strategies, and combines excellent documentation with well-designed protocol extensions. I’d like to set all these wonderful…
We benchmarked 11 data formats, including markdown tables, JSON, CSV, YAML, XML, and more, to see which LLMs understand best. We found surprising accuracy and token cost trade-offs.
How Postgres’ v7 UUIDs are made monotonic, and why that’s a great feature.
