rqlite and Hashicorp Raft Consensus

I’ve started replacing go-raft within rqlite with the implementation from Hashicorp. go-raft is no longer maintained, and I’ve good experience with the Hashicorp code, due to my work with InfluxDB and hraftd. I’m also going to change the API, so…

New browser interface for Ekanite

Ekanite is an open-source Syslog server with built in log search. Thanks to some nice work by Fabian Zaremba, Ekanite now supports searching your logs via a browser. If you’d like to understand more about the design and development of…

Revisiting syslog-gollector

It’s been 18 months since the first commit to my first significant Go project — syslog-gollector. After an initial burst of activity to create a functional Syslog Collector that streamed to Apache Kafka, the source code hadn’t been updated much…

Contributing to InfluxDB

When you’d like to contribute to an open-source project it can be difficult to know where to start. Check out my latest post for the InfluxDB blog, explaining how we on the Core team have curated a set of issues,…

Building a distributed key-value store using Raft

Hashicorp provide a nice implementation of the Raft consensus protocol, and it’s at the heart of InfluxDB (amongst other systems). I wanted to experiment with a simple system built using this particular Raft implementation, so was inspired by raftd to…

Coding like it’s 1999

“Run into an obstacle in what you’re working on? Hmm, I wonder what’s new online. Better check.” If you haven’t already, you should start reading Paul Graham’s essays. In one on philosophy, Graham believes that many of the answers provided…

Who watches the watchers?

I’ve written my first post for the InfluxDB blog. In it I discuss the new statistics and monitoring system built into InfluxDB, starting with the 0.9.4 release. Functionality like this is critical when it comes to running a distributed database…

400 days of Go

It’s been 418 days since my first Github commit of Go code. In that time I’ve written a Syslog-to-Kafka producer, a Raft-based distributed SQLite database, a near real-time log search system, and become a core developer of InfluxDB.

Leadership without Management

I came across another great video about software engineering management, this time by Bryan Cantrill. It’s a really great talk, and discussed in-depth — with plenty of humour thrown in — the importance of Mission to high-performing software developers.

Gophercon 2015

This past week I attended Gophercon 2015, in Denver, CO. It was also a chance to get together with the rest of the InfluxDB team. And because the Go community is still relatively young and small, it was a great…

Code reviews still rule

Recently at InfluxDB we discussed how code reviews fit in during the various stages of development. It’s great to see the team reach consensus about how we should develop software. It made me think more deeply about why I remain…

History of Software Engineering

I recently came across a talk on YouTube titled History of Software Engineering, given by Paolo Perrotta. Normally I find online videos to have a low information-to-time ratio, but this one was excellent. It’s not too long, with plenty of…

Software Development for Infrastructure

Bjarne Stroustrup has another very interesting paper on his website.  Titled Software Development for Infrastructure, it discusses some key ideas for building software that has “…more stringent correctness, reliability, efficiency, and maintainability requirements than non-essential applications.”  It is not a…

Eudyptula Challenge

The Eudyptula Challenge is a series of programming tasks, with the goal of getting one up-to-speed on Linux kernel programming. When I first heard about it, it immediately intrigued me. I’ve written a few production Linux kernel modules in my…

Replicating SQLite using Raft Consensus

SQLite is a “self-contained, serverless, zero-configuration, transactional SQL database engine”.  However, it doesn’t come with replication built in, so if you want to store mission-critical data in it, you better back it up. The usual approach is to continually copy…
