Since I recently joined Google Cloud Platform (GCP), I thought it’s time to get some practical experience with the platform. As a result I’m going to migrate this blog from Rackspace to GCP — specifically I’ll use GCE for WordPress, and Cloud SQL for the persistent database storage.
Moving to CircleCI 2.0
CircleCI, which I used for much of my open-source integration testing, has released version 2.0. Support for 1.0 is finishing in August 2018, so it’s time to migrate my projects.
I’ve started with hraftd. It was pretty easy, but I find the documents for 2.0 are not great.
Monitoring: it’s not just for production
Monitoring — the measurement of your system, the gathering of telemetry, and alerting when it behaves anomalously — is key to running large-scale, modern computer systems. But what many developers today don’t realise is that monitoring can be a key part of your design cycle too.
rqlite and Hashicorp Raft 1.0
Hashicorp
recently released version 1.0 of their Raft consensus package. The Hashicorp implementation, along with SQLite, forms the core of rqlite. rqlite has now been ported to release 1.0 and will be a key change in the upcoming release of rqlite 5.0.
rqlite 4.3.0 released
Moving East
After almost 20 years in the San Francisco Bay Area, I am moving to Pittsburgh, PA, to accept a management role with Google. I am very much looking forward to working at a world-class software company.
It was a great two years at Percolate, and I wish all my old colleagues there the very best.
Happy New Year
2018 sees the ninth year of this blog. Happy New Year to one and all.
I am planning major work on rqlite, as well as more client libraries. I also hope to continue to write on software engineering leadership and management.
rqlite 4.2.2 released
One search to rule them all
This is the third in a series about core data structures and algorithms.
The outstanding characteristic of binary search is that it’s intuitive. Many algorithms are not, but binary search is what people — anyone, not just programmers — naturally execute when looking for an item in a sorted data set.
Ekanite 1.3.0 released
A new version of Ekanite, the syslog server with built-in search, has been released. v1.3.0 includes some bug fixes, including to shard management. It also moves Ekanite to Go 1.9.
You can download v1.3.0 from the GitHub releases page.
The power of sorting
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.
rqlite 4.2.0 released
Windows binaries now available for rqlite
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.
New JavaScript client library for rqlite
Thanks to Justin Morant there is now a new JavaScript client library for rqlite, the lightweight, distributed, relational database.
This library allows you to build both in-browser and node.js applications, that access rqlite. You can check it out on GitHub.
