Neon now has beta support for Postgres Logical Replication. This enables teams to use Change Data Capture (CDC) to observe database changes – such as INSERT and UPDATE operations – and stream these changes to downstream systems. We previously wrote about the benefits of CDC and how it enables Event-...

As a developer building a product, you might want to open up access to your API. But this requires you to solve a few problems: All of this takes work and take time away from actually building your product. That’s where Unkey comes in. Unkey provides API keys a service so that you can safely […]

Given an array of integers ([1, 2, 3, 1, 3, 1]), find the elements which are duplicated. No, we're not interviewing. I'm trying to prevent a user from specifying a reserved value twice. Elsewhere in the file I already have duplicate detection for object tags. val dupes: Map<Int, List<Widget>> = widg...

On-premise and Offline map server can now mosaic different layers with color-toning to create seamless, beautiful maps.

Use Adaptive Retrieval to improve query performance with OpenAI's new embedding models

Anomaly detection for time series is like finding unusual events in a sequence of data over time. It helps identify outliers or deviations from the expected pattern, signaling potential issues or anomalies in the dataset. This is the theory, but how does it translate into practical implementation fo...

Since the last time I had too much fun, I wanted to repeat the experiment by taking another Coding Challenge. This time I'm gonna explain how I implemented an Application Load…

Not impossible that AR has regressed here further, I have not been tracking, we still use this at Discourse: github.com discourse/discourse/blob/main/lib/freedom_patches/fast_pluck.rb # frozen_string_literal: true # Speeds up #pluck so its about 2.2x faster, importantly makes pluck avoid creation of...

Just came across this blog post, and figured I’d try rerunning it with rails 7.1.3 to see what’s changed. It looks like my hardware performs about twice as fast as your benchmarks, except for activerecord, which is only half as fast. Has AR got 4x worse at this task in the interim? Calculating -----...

For the first time ever, I was laid off, and had to find a new software developer job. I managed to find a new one, but it took longer than I thought, and it was a lot of work. I … Continue reading →

Sometimes deep changes take a huge amount of code. Sometimes they take a lot of detailed explanation and consideration, leading to long discussions and people taking sides. Rarely does an important syntactic change to a language happen quickly, with universal agreement, simple implementation, and to...

In this post, we’ll guide you through setting up a scalable serverless API using FastAPI, deployed on AWS App Runner and powered by Neon Postgres as the serverless database. FastAPI is a modern, fast (high-performance), web framework for building APIs with Python 3.8+ based on standard Python type h...

I had a long, meandering journey to get Postgres to properly connect. I was using an Elixir client, Postgrex, but this advice will probably apply generally. Here's how to avoid a particular problem in getting your postgres clients to connect with tcp/ip on localhost.Defining TCP/IPBy default, if you...

Sometimes you need to quickly test your client libraries to make sure that you can connect to Postgres with your tech stack, network and credentials combination.Here are a couple of examples of the simplest connection tests. No previous database migrations are required. The query uses the default po...

Once again it was Hack Week (more than just a day!) at Tumblr! This is getting repetitive in the best way. A couple of times per year we slow down our normal work and spend a week working on scratching a personal itch or features we want as user and see how far we can get with our hacks. One thing f...
