For my projects, I need a generic website setup that I can reuse for multiple projects.
I want to try out the following setup. A frontend build in Vue served as static files from Amazon S3. A backend built with .net core 2.1 as a REST API presented with Swagger. Finally, using Googles firebase authentification for login requirements.
Since I need a baseline platform for multiple projects, it needs to be generic enough to allow me to reuse the setup. Most of my projects need a similar setup with a frontend exposed to anonymous users and a backend dashboard which requires authentification.
In this article, I am going to cover how I set up the Vue frontend. In later articles, I will cover the authentification and the backend.

If you like me have too many domains for different projects, email accounts get a problem. With any domain comes the responsibility to allow people to get in contact with you. Often I use a webmaster@domain or info@domain email address to enable visitors to contact me.
But At $4 / month for an Amazon Work mail account and $5 / month for a Google suite user maintaining many email accounts gets pricey. Also, it is a hassle to monitor all the accounts.
Often you simply want to have emails forwarded to a single email account, where it is possible to set up filters, and allows you to check mail in a centralized place. For example, have email@example.com be forwarded to firstname.lastname@example.org which is my primary email account. With minimum set up.

Real men do not take backups, but they cry a lot
But I rather not cry too much 🙂 I try to have a good backup solution. After all, I do spend an awful lot of time creating data; it would hurt a lot if it were lost by accident. Especially since a backup is easy to set up and cheap.
Amazon S3 is my go-to solution for cloud data storage. It is designed never to lose data and to be resilient to disasters. On top of that, it is cheap.
In this article, I dive into what you need to know about Amazon S3 before you start using it for your backup solution.

We do not log in to our servers every day to check how the resource usage is. Just like with uptime monitoring we need a system to help us monitor if everything is inside reasonable limits so we can scale the servers if required. And detect any potential problem before it becomes a problem.
In this article, I will explore how to set up monitoring using, Docker, influxdb, grafana, cAdvisor, and fluentd.

The latest update in the C# in a Nutshell series, it obviously covers C# 7.0. With 1037 pages it is a massive volume, most of it can be used as a reference book, and many of the chapters are not important unless you have very specific needs. The topic in each chapter is covered in significant detail, you will be hard-pressed to find a detail that is not covered I think.
It can be read, cover to cover, but I would recommend to read the first 4 chapters and pick from the remaining based on interest or need. The detail level and reference book type of writing make the book dry to read, so be warned!
My notes from the book are collected here, I hope they will be useful to someone.

In my continuous effort to make my setup as redundant as possible, the next step is to add a load balancer. I ran into a few problems while setting it up, allowing me to share my experience.
- It is not possible to have the apex record of a domain point to a CNAME.
- Moving the domain names of a service that runs HTTPS requires great care.
I added a network load balancer to sit in front of my Docker hosts to allow them to be fall over for each other. After that, I moved datadriven-investment.com to www.datadriven-investment.com because of the problem with apex DNS record mentioned above.

To improve the load time from the previous article, we must look to caching. I have always been fascinated by technology that allows us to serve pages very VERY fast. So in this article, I am going to explore a few different options for making WordPress load faster using caching.
It is not feasible to make software like WordPress load in less than 100ms, just loading the front page on this blog takes around 400ms which is already fast for a WordPress site. So we need a caching system in front of it to improve the load time.

This article extends the setup explained in the previous article.
Briefly, the setup consists of a load balancer, an HTTP server, and a PHP-fpm backend, all running in a Docker Swarm environment as explained here.
Previously the load balancer was bound to the manager node in the Docker swarm because it needed access to the Let’s Encrypt certificate files. To prepare for a fully replicated and fault tolerant design, this needs to be fixed so it can run from any node.
Because of the mesh network in Docker swarm, the load balancer does not need to run on the manager node where the external IP is bound. It can run on any host; the mesh network will route the request to the right container. But that requires us to replicate the Let’s Encrypt certificates and make sure they can be renewed and reloaded independently of which host the load balancer is running. This article explains how I changed that and moved renewal into Docker.

The book is published in 2014 so it is starting to show some age. Even though ASP.NET MVC 5 is the last version until it changed the name to ASP.NET MVC Core which is in version 2, see the version history here. So why read a four year old book? Many projects still use MVC 5 and it allowed me to gain an overview of the technology before diving into MVC Core. Unless you have a particular interest in MVC 5 I would recommend a book about MVC Core instead.
At 624 pages and 17 chapters, I read it in a couple of weeks. It does start to show it’s age when referencing jQuery and AngularJS, it is rather old versions mentioned. But the chapters about the MVC framework are sound and contains a good walkthrough about each main feature of the framework. If you need a primer on MVC 5 I will recommend it.

Your deployment environment is a tool that should be sharpened to allow maximum productivity. I have seen many developers where their deployment environment is less than optimal, hurting their productivity.
Ranging from, developing directly on production sites. To develop on a shared server. And finally using a local development environment, which I think is the most optimal way to do it.
Developing directly on production is “fast”, but remember the quote
Slow and steady wins the race
If you develop directly in production, the business will be all over you when you break things, and you will break things! So take the time to get a setup that allows you to go fast in the future.
A local development environment has many advantages and with Docker, it is easy to set up. I will show how I handle the setup for my development. Including tip for how you can take advantage of a local development environment.
