VA Smalltalk: Remote controlling Raspberry Pis from Across the World!

You probably know that with my friends Gera and Javier we are working on a Bell tower (called Carrillon) automation using Raspberry Pi, Python and VASmalltalk. Last week, Gera was in his way to Buenos Aires airport to take a plane to Las Vegas. Via chat, he told me he forgot his Pi: he wanted … More VA Smalltalk: Remote controlling Raspberry Pis from Across the World!

Getting started with VASmalltalk, Raspberry Pi and other devices

In the previous post, I described why I personally believe that Smalltalk is a good fit for IoT. When we talk about IoT, there are millions of topics we can touch: single board computers, sensors, security, protocols, edge computing, GPIOs, AI, and so on…   But one device in particular that changed the world is the … More Getting started with VASmalltalk, Raspberry Pi and other devices

Why is Smalltalk a good fit for IoT and edge computing?

I was gonna start a series of posts about Smalltalk, IoT, Edge Computing, Raspberry Pi, etc. But before that, I would like to answer a question that I am asked each time I present something related with these topics. Why is Smalltalk a good fit for IoT and edge computing? Does it have unique features … More Why is Smalltalk a good fit for IoT and edge computing?

Docker Swarm ARM 64 cluster running Smalltalk

In the previous post we saw how to build a single-node Docker Swarm running VASmalltalk. That stack involved one web server (Traefik) load balancing across 10 VASmalltalk images running a Seaside web application. All containers in same node. Preparing the physical cluster Before getting started, know that the code has been published on Github in the same … More Docker Swarm ARM 64 cluster running Smalltalk

Getting started with Docker and Smalltalk!

What is Docker and Linux Containers? Linux containers are a way of virtualization that has been around since quite some time already. Compared to the classical “Virtual Machine” like VMWare, VirtualBox etc that are bulky and heavy to run, containers are lightweight, much smaller and they share the host’s kernel. That is, X number of … More Getting started with Docker and Smalltalk!

Another example of how great the Smalltalk community is

I think a clear example of how great the Smalltalk community is just happened to me once again  during the recent Camp Smalltalk at North Carolina organized by Instantiations. But “the thing” started way before that. I think Tim Rowledge started with some GPIO lib wrapper in Squeak. Louis LaBrunda was interested on having that on … More Another example of how great the Smalltalk community is

Serializing large graphs with SIXX in GemStone

Hi guys, While I promised to start a series of posts about GemStone itself, today I wanted to write down some notes about something I’ve been doing in the last days. Serializing object graphs with SIXX One possible way of moving objects between different GemStone instances or even between GemStone and Pharo, is a serializer. … More Serializing large graphs with SIXX in GemStone

What is GemStone? Part 2

A bit on GemStone history When talking about Smalltalk, one of the advantages always mentioned is its “maturity”. In the previous post, I commented some GemStone features. If you read them carefully, it seems like if we were talking about a modern technology that couldn’t have been possible years ago. Wrong!!!!  GemStone Systems was funded … More What is GemStone?
