Software engineering, distributed systems, databases, and the teams that build them
Software engineering, distributed systems, databases, and the teams that build them
I recently had a chance to speak about rqlite, the distributed, lightweight database built on SQLite, at the University of Pittsburgh Computer Science Club. It was a good evening as I spoke about distributed systems, the problems they solve, and how rqlite…
Go remains one of the languages I’m most productive in. Its combination of the rigour of static typing, but fluidity of Python, makes it both robust and easy to code in. It’s also got some innovative features that help you…
I’ve moved continuous testing of rqlite to CircleCI 2.0. The initial work I did with hraftd was helpful, though rqlite was definitely more involved. Testing is significantly quicker with the new, container-based, version of CircleCI, which should help noticeably with…
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…
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…
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…
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 is a lightweight, open-source distributed relational database, with SQLite as its storage engine. v4.3.0 is now out and includes some new security functionality. You can download the release from GitHub.
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…
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…
rqlite is a lightweight, open-source distributed relational database, with SQLite as its storage engine. v4.2.2 is now out. This release include some minor bug fixes. You can download the release from GitHub.
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…
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.
rqlite is a lightweight, open-source distributed relational database, with SQLite as its storage engine. v4.2.1 is now out. This release include some minor fixes to the CLI, as well as a simple benchmarking tool. You can download the release from…
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…
rqlite is a lightweight, open-source distributed relational database, with SQLite as its storage engine. v4.2.0 is now out. This release moves the build to Go 1.9. You can download the release from GitHub.
rqlite is a lightweight, distributed database with SQLite as its storage engine. Thanks to some work by aka turbo, Windows binaries are now available for download from AppVeyor. Each change now triggers a new build. You can download the latest…
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…
rqlite is a lightweight, open-source distributed relational database, with SQLite as its storage engine. v4.1.0 is now out. This release includes some minor enhancements and bug fixes. You can download the release from GitHub.
I’ve started a new Java client for rqlite, the lightweight distributed relational database, build on SQLite. I’m using Eclipse as my IDE and it’s working well so far. You can check out the source on Github here.
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.
A new version of Ekanite, the syslog server with built-in search, has been released. v1.2.3 includes a fix to the diagnostic output. You can download v1.2.3 from the GitHub releases page.
