On AI Taking Engineering Jobs

     

Introduction

AI has the potential to eventually replace software engineers, but the current iteration of LLMs (large language models like GPT4, Claude, etc) will not be what does it - at least not with how it’s being currently used. I think engineers have an amazing opportunity to ride the wave of a new paradigm of things to build, but it will likely take some effort.

New Kids on The Block

When I was a kid, there was only assembly, basic, and C.

Back in the previous ice age, artists would take samples of old records and remix them. They’d take a bunch of samples of, often old Motown, songs and use them as loops to create new songs. Some of my favourite examples of such artists are Grandmaster Flash & The Furious Five, The Sugar Hill Gang, De La Soul, Vanilla Ice (he’s not one of my favourites, but he is notable), The Beastie Boys, Young MC and one of my all time favourites Public Enemy.

I wouldn’t call myself a musician, but I’ve been playing and recording music since I was a teenager. It’s a hobby of mine that I’ve dabbled with for a long time.

One technique I sometimes use when I am looking for musical ideas is to roll some dice to inspire chord progressions or melodies. Since I’ve been doing more machine learning work over the past few years, I decided it would be a fun project to create a machine learning model to aid in generating musical ideas.

The Simplest Spider

     

In these the days of training models and analysing random things off the internet, sometimes you just need to spider some content off a web site.

If you are going to be doing this for real, some good tools I recommend are:

However, sometimes you just need something quick, dirty and scrappy.

Doing Map Selections Using a Quadtree

     

My methodology to building products is:

I find the faster you can get feedback the faster you can figure out if your hypothesis is correct. The hypothesis being, “my solution solves the problem, and it’s worth building”.

It’s often better not to work on a doomed idea for years and years. Even if the MVP idea doesn’t work out, there will always be some lessons you can learn from them. This post is about one of those cool tricks that worked out well, but the idea surrounding it might take too long to be profitable (for us).

50k Ultramarathon Retrospective

     

I love trail running. I love to hike and tramp; to be in the middle of nowhere with almost no one around. Just me and the planet. Running in the woods is just… it’s just perfect.

I’ve done several smaller trail runs (33k, 24k, and my original love the GutBuster in the Blue Mountains Australia), but I hadn’t broken into the Ultramarathon distance officially until last weekend.

The Taupō Ultramarathon - I’ve been trying to do this race for about 3 years now. In 2021 New Zealand went into lock down, and most everything stopped. The race that year was cancelled - which made sense. The next year I was the lucky recipient of Covid in the middle of my restarted training - so I had to DNS/DNF. But finally… finally the spike proteins aligned, and I was able to show up to the start line.

What Vision Pro Acutally Is (I think)

     

I’ve had some fun conversations with people about Apple’s Vision Pro in the last few days, and a few people sound suspiciously like what Steve Ballmer sounded like when the iPhone first launched.

If you weren’t around back then, there was no AppStore on the phone, you couldn’t send images over text messages, the screen was 9cm (3.5 inches), it only worked on AT&T Edge networks, you had to plug it in to iTunes to transfer contacts and music, it had a 4GB disk, it had a 5 hour battery life, and it cost $500 on top of having to buy a cell phone plan only from AT&T (unheard of at the time).

WASM Raycaster in C with Clang no stdlib

     

I’ve been building software for profit for 25 years now - for fun since I was about 12. For the past year and a bit, I was focused on helping build out and fix some infrastructure. While there was some coding involved, I wasn’t doing much new software development.

I had an urge to shake off a bit of cruft, and do a little “code 5k”. I felt like digging back into some lower level code to stretch my legs - and, of course, throw in some games programming.

SVG as a UI

     

SVG as a UI

Did you know you can put JavaScript into SVG files? You can use this little technique to make little embeddable Flash like applications that also work as standalone applications.

Here is a small example (lightly tested in Firefox and Chrome):

Try clicking around in that image above (or use w,a,s,d to move the circle around). If you view that SVG directly

you’ll notice it works just like it does when it’s embedded.

Mastodon; Machine Learning; Mandarin

     

Mastodon; Machine Learning; Mandarin

TL;DR I made a Mastodon bot that uses Tensorflow, Stable Diffusion and Text to Speech to create flashcard like posts to study for the HSK Mandarin Test. Here is an example:

Introduction

I’ve been studying Mandarin Chinese for quite a while now. Far longer than my ability would dictate.

In the past I’ve studied in waves. I’d study for 3 or 4 months, and then I wouldn’t study for a long while - sometimes years. Then, I’d pick it up again and toddle around with it for a while. Learning Mandarin has become more of a fun hobby than any kind of life goal at this point.
