Intro Hi folks. In the past couple of months I’ve been slowly updating Furnace. There are three major changes that happened. Let’s take a look at them, shall we? Google Cloud Platform Furnace now supports Google Cloud Platform (GCP). It provides the same API to handle GCP resource as with AWS. Namely, create, delete, status, update. I opted to leave out push because Google mostly works with git based repositories, meaning a push is literary just a push, than Google handles distributing the new code by itself. ...

Intro Hi All. Today I would like to write about an AWS finger practice. Previously, I wrote about how I build and deploy my blog with Wercker. Since, I’m a cloud engineer and I dislike Oracle and it’s ever expending tenctacles into the abyss, I wanted to switch to use something else. My build and deploy cycle is simple. Commit to Blogsource Repo -> Wercker WebHook -> Builds my blog using Hugo -> Pushed to a Different Repository which my Github Blog. ...

Hi there folks. Just a quick post, of how I went on and created an IKEA manual about Furnace. Page 1: . Page 2: . I drew these using Krita. I mostly used a mouse but I also used a Wacom Bamboo drawing tabled, for sketches and such. Thanks, Gergely.

Hey folks. Quick note. Furnace now comes pre-compiled easy to access binaries which you can download and use out of the box. No need to install anything, or compile the source. Just download, unzip and use. Here is the website: Furnace Website. Enjoy, Cheers, Gergely.

Intro A while ago, I was added as a curator for a Gem called JsonPath. It’s a small but very useful and brilliant gem. It had a couple of problems which I fixed, but the hardest to eliminate proved to be a series of evals throughout the code. You could opt in using eval with a constructor parameter, but generally, it was considered to be unsafe. Thus, normally when a project was using it, like Huginn they had to opt out by default, thus missing out on sweet parsing like this: $..book[?(@['price'] > 20)]. ...

Intro Hi folks. Previously on this blog: Part 1. Part 2. Part 3. In this part we are going to talk about Unit Testing Furnace and how to work some magic with AWS and Go. Mock Stub Fake Dummy Canned Unit testing in Go usually follows the Dependency Injection model of dealing with Mocks and Stubs. ## DI Dependency Inject in short is one object supplying the dependencies of another object. In a longer description, it’s ideal to be used for removing the lock on a third party library, like the AWS client. Imaging having code which solely depends on the AWS client. How would you unit test that code without having to ACTUALLY connect to AWS? You couldn’t. Every time you try to test the code it would run the live code and it would try and connect to AWS and perform the operations it’s design to do. The Ruby library with it’s metaprogramming allows you to set the client globally to stub responses, but, alas, this is not the world of Ruby. ...

Intro Hi folks. Previously on this blog: Part 1. Part 2. Part 4. In this part, I’m going to talk about the experimental plugin system of Furnace. Go Experimental Plugins Since Go 1.8 was released, an exciting and new feature was introduced called a Plug-in system. This system works with dynamic libraries built with a special switch to go build. These libraries, .so or .dylib (later), are than loaded and once that succeeds, specific functions can be called from them (symbol resolution). ...

Intro Hi folks. Previously on this blog: Part 1, Part 3, Part 4 In this part, I’m going to talk about the AWS Go SDK and begin do dissect the intricacies of Furnace. AWS SDK Fortunately, the Go SDK for AWS is quiet verbose and littered with examples of all sorts. But that doesn’t make it less complex and less cryptic at times. I’m here to lift some of the early confusions, in hopes that I can help someone to avoid wasting time. ...
