For a few years now, I’ve been using Hugo for my website as well as other websites as well. My first Hugo website was my own since I wanted to learn more about the technology before suggesting it to anyone else. Back then I was not able to find any minimalistic theme I liked, and for that reason, I started my own. As you can imagine from the name, I based it on Bootstrap, version 3 since that was the current version when I started to work on it.

This year, as it has happened for the last few years, I’ve been at FOSDEM. As always I’ve enjoyed it a lot, and that’s why I continue to go there, and every time I have to suggest other people which events to attend in Europe, I always mention FOSDEM as the main event. This year, differently from previous editions, I tried to stick to a single room both days, being mostly in the Go room on Saturday and in the Containers room on Sunday.

Today the IT world is very focused on high performance, high throughput interfaces. In this situation, it is common to find REST and gRPC API, given their performances compared to the other solutions. Sometimes, though, we still encounter old API written with older techniques or new API that for some reasons have been developed with outdated technologies. One of those cases that I’ve encountered a few times over the last few months is SOAP.

There are some pieces that you need to put in every microservice you write. Those are for instance logging, error handling, authentication. Over the last year, I found myself writing over and over CORS headers. This requirement brought me to think that I should have used a Negroni middleware since we are already using Negroni for other middlewares. I started looking online for an already written one, and I found a bunch, but I was not happy with what I found, so I decided to write my own.

Golang forces its users to use the repository URL of the dependency in the import statement. For instance, if we want to import the “test” package that is hosted at github.com/fale/test, we will need to use github.com/fale/test. In one hand this is very nice since it allows anyone reading the code to immediately understand where the code is hosted and therefore finding it very quickly. Also, this URL-based import path guarantees that no two different packages can have the same import path, preventing this kind of confusion for both programmers and the compiler itself.

Lately, I found myself to work on an application that was communicating via SOAP with a server. My goal was to understand how this application worked with the SOAP server to emulate its behavior. Even if I had access to the source code of the application, I thought it would have been easier, faster and more fun to do the work without actually reading the code. It’s important to note that actually, the application is fairly small and self-contained.

If you have ever used Docker or any other Linux OCI container system, you inevitably have incurred in the following error: x509: failed to load system roots and no roots provided This message is remembering you that you forgot to provide Root Certificate Authorities to your application. There are two different ways to solve this: mount the /etc/ssl/certs folder from the machine where the container is running bundling the root CAs in your image As you may imagine from the title, I believe that the second option is by far better than the first one.

Lately, all website are urging their users to enable second-factors. The push for multi-factor logins is a good thing from my point of view, since the people are putting more and more details of their life online and is a good thing that companies start to understand the security implication of this and are trying to teach their users good security practices. The real problem is what is defined as second-factor.

A couple of months ago, I wrote a blog post about why containerization is not always the answer and I’ve received quite a few comments about it. This article has the goal to analyze an aspect in favor of containerization which I believe to be true but was not mentioned in the previous post: the time aspect of the phenomenon. In the ICT sector, we are used to new technologies, or at least we should be.

As many other clouds, Google Cloud Platform provides an Object Storage service, Google Cloud Storage. As many other Object Storage service, Google Cloud Storage provides an HTTP server to deliver your files quickly. When I started to use Google Cloud Storage and its HTTP server I have not been entirely pleased by how it works and therefore I wanted to re-implement the HTTP server so that I can manage it completely.
