An evergreen question: what is an MVP?
I was asked this the other day. My answer was: it depends on the context; it helps to have an example. And the contextual element is probably why this remains an evergreen question. While I have a fresh example in mind I thought I’d quickly plant a stake in the ground for reference. First, it…

A resilient charging planner
Check out the prototype of trippler, an interactive charging planner for resilient EV road trips. Based on my own EV road trip experience, trippler is as much about easily understanding charging options and contingencies, to reduce charger anxiety, as it is about coming up with a single best plan. Features Simply enter the start and…

Data complications
Solving EV charger anxiety used maths for better road trips, but skipped over using real data. Let’s fix that, or at least try to… The easy bits I used Open Route Service to find a base route to a destination and and Open Charge Map to find chargers near the route – thank you to…

Solving EV charger anxiety
Many EV adventures are accessible using the charging network in Victoria, but faulty chargers still have the potential to induce charger anxiety on road trips. Planning apps–EV drivers’ constant companions–may not fully solve this when the reported status of chargers is unreliable and faults are prevalent. As a driver, I want resilient plans that already…

EV snow’d tripping
Adventures with EVs often involve big mountain climbs, which consume additional energy, impacting range. I recently had the opportunity to drive climbs from Bright to Omeo and back via Mt Hotham, in Gunaikurnai and Taungurung country, and get a sense for how EVs handle hills. I collected efficiency data for each leg of a road…

EV adventuring with resilience
Road trips are the most demanding EV use case currently in Australia, especially to remote destinations. However, a little planning shows that they are still quite doable. Did the plans survive contact with reality? Mostly. In short, it was a pleasure to drive an EV long distances and the only inconvenience was faulty public charging…

EV adventuring
Electric Vehicles (EVs) are great for weekend adventures and more. In Australia in 2024, it still requires a little extra planning, but many adventures are achievable with that little extra, and as infrastructure continues to improve, there will be ever less transport planning for ever more adventuring! For the time being, I’ll run you through…

Privacy puzzles
I contributed a database reconstruction attack demonstration to the companion repository to the excellent book Practical Data Privacy by my colleague Katharine Jarmul. My interest was piqued by my colleague Mitchell Lisle sharing the paper Understanding Database Reconstruction Attacks on Public Data from the US Census Bureau authors Simson Garfinkel, John M. Abowd, and Christian…

Maths Whimsy with Python
At PyCon AU 2023 in Adelaide I delivered a talk titled Maths Whimsy with Python. It was a great chance to review a range of projects small and large I’ve already shared here. Check out the slides and video. In three years of the maths whimsy repo, I’ve covered a lot of ground, and got…

Electrifying the world with AI Augmented decision-making
I wrote an article about optimising the design of EV charging networks. It’s a story of work done by a team at Thoughtworks, demonstrating the potential of AI augmented decision-making (including some cool optimisation techniques), in this rapidly evolving but durably important space. We were able to thread together these many [business problem, AI techniques,…
