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 — 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.
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.
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.
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.
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.
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.
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.
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.
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
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.
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.
A Google Group for rqlite discussions has been created. This should be a faster way to learn more about the uses, design, and implementation of rqlite.
Check it out here.
