This is the second in a series about core data structures and algorithms.
Considering how important sorting is to computer science and programming, it’s actually a mystery why more programmers don’t appreciate it.

rqlite 4.2.1 released
Hash tables distilled
This is the first in a series about core data structures and algorithms.
Many explanations of data structures focus on the implementation — and that is very important — but I’ve always found some context makes it so much easier to learn. And the trade-offs between various data structures is one of the most interesting contexts you can study.

A shared code base does not a software team make
I’ve been programming for many years, and have spent most of the last few years managing development teams. I’ve written plenty of closed source software, and for a time made my living writing open source software too.
One thing stands out: a shared code base does not a software team make.

rqlite 4.1.0 released
Java client for rqlite
rqlite v4.0.1 released
rqlite
is a lightweight, open-source distributed relational database, with SQLite as its storage engine. v4.0.1 is now out. This release includes some minor bug fixes.
You can download the release from GitHub.
Go, gRPC, and PostgreSQL
I’ve started experimenting with Go and gRPC. To that end I’ve written a simple service that accepts connections from gRPC clients, allowing those clients to send queries to PostgreSQL.
So far it’s been pretty straightforward. You can check out the code on GitHub.
rqlite now available with node-to-node encryption
rqlite is a lightweight, open-source distributed relational database, with SQLite as its storage engine. It’s been over a year since the last major release and v4.0.0 is now available.

Percolate at the San Francisco Python Meetup
The new Analytics system, built by my team at Percolate, allows our end-users to program their own custom calculations, offering them the ability to precisely customize the product for their needs.
At the center of that feature is a Pratt Parser. Percolate recently presented on this topic at the San Francisco Python Meetup. You can find the slides here, and code here.
rqlite v3.13.0 released
rqlite is a lightweight, open-source distributed relational database, with SQLite as its storage engine. v3.13.0 is now out. This release includes minor enhancements and a couple of bug fixes.

rqlite v3.12.1 now with Discovery Service for easier clustering
rqlite is a lightweight, open-source distributed relational database, with SQLite as its storage engine. v3.12.1 has been released. This release includes integration with a new Discovery Service, allowing nodes to automatically connect and form a cluster. This can be very convenient, allowing clusters to be dynamically created.
You can download the release from GitHub.
Building a cluster discovery service with AWS Lambda and DynamoDB
In this post I describe how I built a serverless cluster discovery service for rqlite, the distributed relational database built on SQLite.
Built using the AWS API Gateway service, AWS Lambda, and DynamoDB, it means rqlite nodes no longer need to be passed the network address of an existing node in a cluster, and can instead connect automatically.

Building a snap for rqlite
I’ve started experimenting with one of the newest packaging systems — Canonical’s Snap format.
I learned about Snap from Mark Shuttleworth when he let me know that he had created a rqlite Snap. It seems pretty clean and straightforward so far — I’ve already started working on my first snap for rqlite, and plan to publish a version as a Ubuntu app.
rqlite v3.8.0 released
rqlite is a lightweight, open-source distributed relational database, with SQLite as its storage engine. v3.8.0 is now out. This release includes some minor enhancements and bug fixes.

Stop asking “how much data do you have?”
In every field there is a question that, while it sounds interesting, betrays a naiveté and lack of sophistication.
In my field — SaaS and data platforms — it’s how much data do you have?
