ColoriseBot: three months on

For DockerCon EU in Copenhagen back in October, Oli Callaghan and I developed a Twitter bot backed by OpenFaaS with help from Alex Ellis. How it works Just tweet a black & white photo to @colorisebot! What happened next? The bot was a great success during the conference but soon dropped off afterwards. Then, half way through November, Matthew Hughes wrote an article on The Next Web showing off ColoriseBot. A few minutes later, the bot was swamped with requests in the hundreds-per-minute range. After a few teething issues and working late into the night with Alex, we came up with solutions to the load problems we faced and were able to develop a far more error-tolerant service complete with continue...

Colourising Video with OpenFaaS Serverless Functions

Introduction In a previous post I talked about how to deploy serverless functions to an OpenFaaS cluster with ease. This post expands on this to show how we deployed a Machine Learning algorithm to colourise black & white videos using OpenFaaS. We presented the end result of this at DockerCon EU 2017 in the Community Theatre in Copenhagen. In the beginning After DockerCon in April of this year, I spotted this post on Mashable with some really cool examples of colourised photos from World War Two. This really hit home with me because they really bring the era to life; colour photos give you far more context than monotone photos do. I started to wonder how feasible it would be continue...

DockerCon 2017 - highlights & experiences

So, DockerCon! It turns out that building cool stuff gets you places. Back in 2016, I built a Docker Swarm from 5 Raspberry Pis by following Captain Alex Ellis’ tutorial and then went on to create two different visualisations for the swarm to demonstrate real time load balancing. This was picked up by Alex who got in touch soon after with the amazing news that Docker wanted to invite me to DockerCon17 in Austin, TX! I was incredibly excited about the prospect and asked if I would be able to give a talk showing some of the things I’ve done with Docker, so it was to my delight that they agreed. What is DockerCon like? DockerCon is the most continue...

TweetDock at DockerCon

A couple of weeks before DockerCon 2017, Victor Coisne asked me whether I would like to create a demo for the DockerCon museum. Having built a hardware gauge with two dials already, it wasn’t going to be very hard to build another! This time, instead of showing load on a swarm, I hooked the dials up to the Twitter Search API to monitor the usage of #DockerCon on Twitter in real time. This was a really fun and quick project to build as I already knew how to make all the hardware. The code is very simple, in essence what it does is: Connect to the Twitter API & configure the servos Every 5s, query the API for the continue...
