This week I came across the library Immer as a convenient way of manipulating immutable data in JavaScript. After reading this Reddit thread that raves about how much better Immer is than Immutable.Js, I was worried I’d made the wrong decision to use Immutable.js in Microvium. But some performance tests quickly cleared up my concerns. …
This post is different from my usual topic of Microvium. I’ve been recently frustrated with the way that distributed applications are written and I’ve been brainstorming ways it could be improved. In my last post on the topic, I suggested that maybe a new programming language would be useful for solving the problem, but I …
It’s an age-old debate, but as I get older, my perspective is changing. I feel increasingly frustrated by tools that don’t work smoothly; tools that weren’t thought out very well. And I ask myself, wouldn’t my life be better without these? TL;DR The economic incentive for product development is not always aligned with what makes …
TL;DR I think it would be great to have a language where single instance of a program can run non-stop for 10 years across a dynamic, heterogeneous mix of hardware, where the program code can perform its own allocation and management of infrastructure resources such as databases, VMs, and public IP addresses, as well as …
It’s only been a few weeks since the Alpha release of Microvium and I’ve already almost rewritten the engine! There are two major changes I wanted to make to improve performance: I’ve moved to a great new garbage collection algorithm which is much faster and has a smaller memory footprint in both RAM and codespace. …
TL;DR: This Microvium plugin (in development) optimizes Microvium bytecode by statically determining which variables and properties are accessible and how they might be accessed (read vs write), to decide whether to safely store them in ROM or remove them completely from the bytecode. With the recent alpha release of Microvium, I’ve since turned my attention …
Microvium version 0.0.9 is published on npm, marking the first alpha release of Microvium! ? I’m pleased with how quickly this has come together in the 4 months since I started the project back in February. Be ready for good things still to come! Subscribe to my blog if you want to be notified of …
The Microvium garbage collector is here! The garbage collector handles the automatic freeing of unused heap memory in the VM. Microvium makes some interesting and perhaps unique tradeoffs with garbage collection which I’ll focus on in this post. I’ll divide this post into two parts to cater for different audiences: I’ll start with a summary …
I’ve made a lot of progress on Microvium over the past month and will share some of the details here for those who are interested. I think it’s really close to being ready for an alpha release, with the garbage collector being the only remaining piece of work before it can start being used. Summary …
TL;DRBunding and snapshotting are two different ways of packing a program for deployment. This post is a somewhat-biased overview of why snapshotting is clearly superior in many respects. I recently wrote up an explanation of Microvium snapshotting, along with this hopefully-helpful animated diagram: In short: the diagram depicts a running Microvium (JavaScript) application that is …
