Reader’s Digest I thought it would a cool idea if I kept a summary of the things I’ve read or listened to on a monthly basis. Here is January of 2021 so far. Enjoy. All systems red - Murderbot This book is SHORT. It’s little over 3 hours of listening time. I’m listening at 1.30 so it’s just short of 2 hours. But it’s entertaining. The murderbot series is following a rouge security bot which hacked its own governor module and is self aware and free. But… it kind of hates humans and interacting with them. It just calls itself murderbot but has no intention of killing all humans. Instead, all its wants to do is basically… watch movies and various series on something called a Feed. In the first book of the series, this one, we follow Murderbot protect a few humans that it gets to short of like after an attempt on their lives. ...

Intro Welcome. This is a longer post about how to deploy a Go backend with a React frontend on Kubernetes as separate entities. Instead of the usual compiled together single binary Go application, we are going to separate the two. Why? Because usually a React frontend is just a “static” SPA app with very little requirements in terms of resources, while the Go backend does most of the leg work, requiring a lot more resources. ...

Intro Hi folks. This time, I would like to talk a little bit about code reviews. How do you do code reviews? Don’t hesitate to share it in the comments. How do I do code reviews? Well read on if you would like to know. The Top Down approach If I’m dealing with a small code change, a couple of lines here and there in the odd file first, I’ll try to understand why the review is there? What was it trying to achieve? What’s the goal of the change? Is there a ticket/issue I can read for background info? Or an RFC? ...

Intro Hi folks. Today I would like to share a quick “fix” for a problem I’ve seen popping up here and there. That is, if you have a react frontend which is a SPA app but you still want refresh to work. What do I mean by that? Consider the following… The problem You have a SPA app with a react router which navigates the user around. The app calls to a backend api which serves content of some kind. You have the following routes…. login, signup, reset, archive. ...

Intro Hi folks. This is a continuation of the previous post about my Kubernetes infrastructure located here. The two remaining points are to deploy Athens Go proxy and setting up monitoring. Athens Let’s start with Athens. First of all if you are a helm user, Athens has an awesome set of helm charts which you can use to deploy it in your cluster. Located here. I prefer to deploy my own config files, but that’s me. So here is my preferred way of deploying Athens. ...

Intro One morning I woke up and tried to access my gitea just to find that it wasn’t running. I checked my cluster and found that the whole thing was dead as meat. I quickly jumped in and ran k get pods -A to see what’s going on. None of my services worked. What immediately struck my eye was a 100+ pods of my fork_updater cronjob. The fork_updater cronjob which runs once a month, looks like this: ...

Intro Hi folks. Today, I would like to show you how my infrastructure is deployed and managed. Spoiler alert, I’m using Kubernetes to do that. I know… What a twist! Let’s get to it. What What services am I running exactly? Here is a list I’m running at the time of this writing: Athens Go Proxy Gitea The Lounge (IRC bouncer) Two CronJobs Fork Updater IDLE RPG online checker My WebSite (gergelybrautigam.com) Monitoring And it’s really simple to add more. ...

I had a lot of fun using Procreate to re-draw the architecture image I’ve drawn for my distribute face recognition application detailed in this post Distributed Face-Recognition App. Without much fanfare, here is the drawing: Thanks, Gergely.

Intro Hi folks! Today I would like to write about a metric that I read in a book called Clean Architecture from Robert Cecil Martin ( Uncle Bob ). Abstract The metrics I mean are Efferent and Afferent coupling in packages. So you, dear reader, don’t have to navigate away from this page, here are the descriptions pasted in: Afferent couplings (Ca): The number of classes in other packages that depend upon classes within the package is an indicator of the package’s responsibility. Afferent couplings signal inward. (Affected by this package) (Fan-In). ...
