Recently, due to work-related reasons, I took a moment to revisit Open Policy Agent and discovered that the Cedar Language introduced by AWS is more suitable for implementing a policy mechanism similar to AWS IAM in software applications. Since it is built on Rust, I decided to try writing an extension in Rust so that it can be utilized in Ruby.

mruby compiles source code using a compiler (usually mrbc), resulting in a binary file in the mrb format. This file format is called RITE, and in order to execute compiled mruby code, it needs to be parsed and read.

Even Ruby on Rails is one of the fastest frameworks of web development, and we can use it to build a web rapidly. We still need the DevOps to deploy or update it manually that we can test or release it.

Can we have a better way to resolve it?

We have 4 ~ 5 times meetup in TGONext, and this time is the last meetup in the schedule. In the possible last meetup, we discuss some topic which we are not planning to discuss at first.

This time we are talking about log tracing and how to deal with technical debt.

The Form Object is a common pattern in Rails when our form becomes complex. But the tutorial in network’s example usually incapable of Rails’ form helper.

And I start thinking about is it possible to support form helpers without too many changes?

A few years ago, I have a post talking about Autoloading. In recent days, my colleague has some problems with Autoloading and Reloading.

Therefore I decided to review the Autoloading mechanism in Rails 5 and 6.

Before we starting to discuss architecture, our mentor let us ask some questions.

Between this meetup and previous meetup, my customer breaks their migration due to some incorrect plan. So I raise a migration question to discuss the zero-downtime migration plan.

This meetup we review previous discussions and switch to the next topic. Based on the high concurrency we talk about the last meetup, we simulate an architecture and evolution it.

About 1 year ago, I build a Ansible playbook for the customers of 5xRuby.

When our customers grow it is hard to use the fork feature to maintenance our customer’s playbook.

I have to update the main version and sync the changes to the fork version for each customer. Therefore I decided to split the common parts to a single role repository.

Yesterday is the first meetup of the TGONext project, we are learning from Taiwan’s high-level technical leaders. After the opening, our mentor Ant let our polling for the topic we want to discuss in this half-year project time.

We decide to pick up 4 topics to discuss and the first topic is “high concurrency.”
