So I’m going to explain some of the reasons and provide basic tips on how to improve start […]
How to Generate Random Numbers in Smallworld GIS
I have some good news and some bad news. What was that? You want the bad news first? Okay… There is no way to generate truly random numbers outside of quantum physics. But what about rolling dice? Nope. Rolling dice only appears random because we can’t measure all the various physical factors that produce one […]
A Magik Blockchain
I’ve written quite a few articles about using Functional Programming (FP) with Magik on this site, and provided detailed code examples. However I haven’t yet put together an entire FP application. So let’s do that now. But rather than follow the same-old-same-old and write a standard GIS app, we’ll hook into one of the hottest […]
How to Run GSS Locally without Docker and Kubernetes

Part of what puts the, “strength,” in, “industrial-strength,” is the fact it is deployed using Docker containers managed and orchestrated by Kubernetes. However deployment can be a complicated affair, and in many cases we simply want to develop services without […]
Virtual VMDS in Smallworld GIS
Starting in version 4.3, Smallworld GIS images/sessions can use a virtual VMDS by passing the -vvmds flag. For example: d:\smallworld\core\bin\x86\runalias.exe -vvmds -a d:\smallworld\cambridge_db\config\gis_aliases cambridge_db_open This is useful when you want to be able to restart from a known state without having to use checkpoints. It’s also extremely helpful when doing work with Alternatives. If, for […]
