As I commented in an earlier post, one of the great features VASmalltalk has in the context of IoT, is a wrapper of the C library pigpio which allows us to manage GPIOs as well as their associated protocols like 1-Wire, I2C, etc. In this post we will see the basic setup for getting this … More Beginners guide to GPIO in VASmalltalk
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
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?
Previously… In the previous post we saw an introduction to Docker and Linux containers and one possible usage for Smalltalk. We saw how to create the Dockerfile for a Seaside web application developed and running within VASmalltalk , build a Docker image, and finally run a container with it. However, one of the conclusions from … More Now, single-node Docker Swarm 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!
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
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? Part 2
What is GemStone When you ask a Smalltalker what Smalltalk is, you will find many different answers: a language, an environment, an object system, a platform or simply a combination of all of those or more. With GemStone, I have a similar feeling. I think different people will answer differently. To me, GemStone is an … More What is GemStone?
