I did it my way – hand-rolled navigation with open spatial data
Sure commercial maps app directions are great, but have you ever found the customisation options limited? What if you want to use bike paths and back streets when cycling, or avoid winding roads that might make backseat passengers car-sick on a road trip? The paved route OpenStreetMap and OpenRouteService do provide this type of functionality,…

Nerfing along
NeRFs provide many benefits for 3D content: the rendering looks natural while the implementation is flexible. So I wanted to get hands on, and build myself a NeRF. I wanted to understand what’s possible to reproduce in 3D from just a spontaneous video capture. I chose a handheld holiday video from an old iPhone X…

Throwback Thursday
The metaverse is a topic currently, though the concept has a long history. Twenty years ago, in the dotcom era, I was exploring this space, as I was recently reminded. Feeling nostalgic, I dug these projects out of the NAS archives. Tech has moved on, but there’s enduring relevance in what I learned. VO2max (1999)…

Synthesising Semantle Solvers
Picking up threads from previous posts on solving Semantle word puzzles with machine learning, we’re ready to explore how different solvers might play along with people while playing the game online. Maybe you’d like to play speed Semantle against an artificially intelligent opponent, maybe you’d like a left-of-field hint on a tricky puzzle, or maybe…

Second Semantle Solver
In the post Sketching Semantle Solvers, I introduced two methods for solving Semantle word puzzles, but I only wrote up one. The second solver here is based the idea that the target word should appear in the intersection between the cohorts of possible targets generated by each guess. To recap, the first post: Solution source…

Sketching Semantle Solvers
Semantle is an online puzzle game in which you make a series of guesses to discover a secret word. Each guess is scored by how “near” it is to the secret target, providing guidance for subsequent guesses, but that’s all the help you get. Fewer guesses is a better result, but hard to achieve, as…

Visualising System Dynamics Models
Simulation is a powerful tool for understanding and solving complex problems, but sometimes simulations themselves can be hard to understand. Visualisation is a powerful tool for understanding what simulations are telling us, and also for socialising the limitations and assumptions built into predictions. An approach System dynamics is a simulation paradigm that can be used…

Slackometer Hello World
Project Slackpose gives me one more excuse for hyperlocal exercise and number crunching in lockdown. Last time, I briefly touched on balance analysis. This time, I look at tracking slackline distance walked with my newly minted slackometer. Inferring 3D Position I’m working only with 2D pose data (a set of pixel locations for body joints)…

Project Slackpose
Another lockdown, another project for body and mind. Slackpose allows me to track my slackline walking and review my technique. Spending 5 minutes on the slackline between meetings is a great way to get away from my desk! I had considered pose estimation for wheelies last year, but decided slackline walking was an easier start,…

LEGO and Software – Part Roles
This is the fifth post in a series exploring LEGO® as a Metaphor for Software Reuse. A key consideration for reuse is the various roles that components can play when combined or re-combined in sets. Below we’ll explore how we can use data about LEGO parts and sets to understand the roles parts play in…
