One commenter on my arduino curve-fitting post asked if it was possible to fit to nonlinear functions as well, such as a decaying sine wave. I said I had no idea, so I did some research and found the Levenberg-Marquardt algorithm. The LM algorithm takes …
I’ve just finished a research project focused around creating a general classifier for a large data-set. It deals with time series data, and as such must split this time series data into segments using change point detection. In one of the cost functions I was …
I’ve been working for a startup for the past few months, which has been a (mostly) delightful experience compared with corporate hell. We use Azure every day of the week to deliver best-in-class data gathering and insights in a fairly niche market. This cloud experience …
Today’s Engineering sector is, and always has been, full of extremely driven and talented people. The driver for success in this relentless space, in my mind, is differentiation. Here a little left-of-field knowledge goes a long way. Scott Adams says that even if you know …
How to use LightSource Once you’ve installed LightSource, open your favorite part and go to the render workspace, to launch LightSource click on this lightbulb: This should launch the command window: Vertical and Horizontal handle the Azimuth and Polar angles for the orientation of the …
If you’ve ever tried to make consistent, fairly passable-looking forms, your first knee-jerk reaction is probably to reach for Bootstrap. Now it offers a number of great out-of-the box options for forms, one of which I use regularly is split buttons as a radio. It …
I’ve been doing a bit of reading recently, and starting with one of Bret Victor’s talks, some of his references and Paul Graham’s essays I’ve ended up in a rabbit hole I’m quite enjoying. Weird computation, mostly centred around the LISP family of programming languages. …
If you’ve got a Content Management System and a lot of content to populate it with, as some large companies might, it could take weeks just to do one site. Even generating just the page structure might take a day. Automatically creating the structure and …
Recently I’ve been thinking about the difficulties of device discovery on a local network with DHCP, i.e. no static IPs. Especially with an IoT system you want to send out to a customer, prefilled with SSID and password information, who can just plug it in. …
So we can read an excel sheet, and manipulate a browser – how do we put these skills together to do something that saves us time (= money)? Divide and conquer When approaching any programming problem, I like to break it down into chunks. It’s …
