Curated sample training datasets for Machine Learning for Kids

Wednesday, June 26th, 2019

Machine Learning for Kids now includes support for a curated collection of training data sets, to enable children to create different types of machine learning projects.

The tool lets children make things using machine learning. The principle I’ve worked to is that children train their own machine learning models, as doing this is a great way to teach them about how this tech works.

Preparing their own training data is a useful exercise, but it is time-consuming. Project worksheets I’ve written so far have all been written with the assumption that the student will prepare the training data within a single lesson. This has been a limiting factor on the kinds of ML projects I’ve been able to include.

Using nginx to enable custom domains in Auth0

Sunday, December 2nd, 2018

In this post, I’m sharing the nginx config needed to set up a reverse proxy for enabling custom domains in Auth0.

I’ll start by explaining why I needed this, but if you don’t care about that, you can just skip straight to the code.

I’ve mentioned before that I use Auth0 for authentication and authorization in Machine Learning for Kids. (And I’ve mentioned before that the developer experience using Auth0 is generally fantastic).

But I’ve had one auth-related complaint from schools since launching the site. And it’s been increasing in the last couple of months:

Users who have their web browsers set to block third-party cookies weren’t able to log in.

This is because the cookies were coming from an auth0.com domain, and not machinelearningforkids.co.uk.

Running a multi-region Cloud Foundry application in IBM Cloud

A few technical details on how I’m implementing global load balancing to improve the availability of Machine Learning for Kids.

This wasn’t a great week for Machine Learning for Kids. I think the site was unavailable for a couple of days in total this week, spread across a few outages – the worst one lasting over twelve hours. I know I’ve lost some users as a result – a few teachers / coding group leaders did email me to say (not at all unreasonably) that they can’t use a tool that they can’t rely on.

I wrote in my last post that I would be making changes to prevent this sort of thing from happening again. Now that I’ve done it, I thought it’d be good to share a few details on how I did it.

How I ended up making MachineLearningForKids

Sunday, October 29th, 2017

I write a lot about what I’m doing with machine learning for kids, but in this post, I want to share a little about how I ended up doing it and why.

I tend to write about *what* I’ve done. I rarely write how things happened though, or what made me do them. I just assume that people would be less interested in that.

But, if I think about what I find interesting, it tends to be the backstory to projects. To use Nick as an example, I’ve seen him give loads of talks about Node-RED. And I’ve enjoyed the ones where he talks about how Node-RED happened more than where he gives demos of what Node-RED is.

Inspired by that, I thought I should at least try to capture a few breadcrumbs for how I ended up where I am now with machinelearningforkids.co.uk.
