After getting a “Hello, World!" WebAssembly
application working I thought it would be fun to try and implement a toy programming
language in the browser. However before I could even start thinking about parsers,
abstract syntax trees and the like I had to be able to pass strings between my
WebAssembly is something I’ve wanted to play with for quite a while now and
I’ve finally got around to taking a look at it. In this post I describe how I
managed to use TinyGo to compile a “Hello, World!” Go program into
WebAssembly and execute it in the browser. So that I have something to refer
back to I also describe setting up my development environment as a container
Being an API for talking to GPUs and other compute devices every Vulkan
program starts off by looking for an appropriate physical device
to use. In this post I write a little C program that initialises the Vulkan
API and lists out the available devices in the system.
I have always been interested in graphics and have on numerous occasions tried
to dip my toe into the world of OpenGL and more recently Vulkan. However I have
never been able to get past the “Hello, World” of these technologies - drawing a
triangle on screen, I think mostly becuase I never really had a goal in mind
once I got that far…
But that’s (hopefully) about to change! What better excuse than a new decade to
jump back into this world for the 100th time and try to get to all those
interesting ideas I see people playing with all the time!
This post makes use of a number of interactive elements to help illustrate a few
concepts. Unfortunately these do not yet work on mobile devices - sorry mobile
I have for quite some time now wanted to play around with web development some
more, particularly using web technologies to build user interfaces of some
kind. However there is just so much out there it’s been impossible for me to
really get anywhere past a “Hello, World!” tutorial before I find myself trying
out the next new shiny.
So I’ve decided to abandon everything and try a bottom up approach where I see
how far I can push the core web technologies - HTML, CSS and
libraries out there I will have a better understanding of why I
needed it in the first place.
In this post I will be looking at implementing clicking and dragging
can apply to many kinds of interactions so in this instance I’m specifically
referring to clicking on an SVG element moving it around on the page as
illustrated by the demo above.
A few weeks back at PyConUK I gave my first lighting talk
at a conference. During that talk I spoke publically about stylo for
the first time. Stylo is a Python library that I have been working on for just
over a year and a half and it aims to make the creation of images easier by
bringing together ideas from programming and mathematics.
Version 0.6.0 was recently released which included the first feature
that wasn’t written by me! It’s very exciting not only to see other people
starting to take an interest in the project but taking the time to make a
Now that stylo seems to be getting to the point that it might me useful to
other people wouldn’t it be great if there was a community driven example
gallery that people could get inspired by? - Well now there is! And it’s
called Stylo Doodles
Not that you would have known it, but I’ve had a blog since 2014. Well 2015 if
you’re feeling generous, the first (and only) post went up in the last few
hours of New Year’s Eve. It was a look back on some of the projects I had
worked on that year and I announced my intentions to start blogging.
Fast forward nearly 4 years and here I am announcing my intentions to start
blogging - again. So I guess you are wondering what happened?
I got lost.
My first attempt at running a blog was using Jekyll and for some mystical reason
(It’s been so long I can’t actually remember why), I decided that it was not the
static site generator I was looking for. So I promptly set off on a voyage of
discovery in search of the ultimate static site generator.
