Human-readable tests in Golang with BDD
 golang  testing  bdd
Testing your application is possible on so many levels. You start with unit tests for specific places in the source code, then you add integration tests that check interactions between different places in the system. You can wrap things up with some functional tests, which are either done manually or automatically using tools like Selenium. The problem is that you need tech knowledge for most of those steps. But what if I told you that you can give your business people, managers and project managers tool to add tests on their own? Say hello to BDD!
Deploying Go with Docker to Heroku
 heroku  docker  golang  cloud
Building web applications can feel very rewarding, once you see some effects in the browser on your very own `localhost`. Unfortunately, it's harder from there on out, as you need to figure out how to share your project with the _outside world_. I've struggled often at this point as I was never sure if I should already share the project with the world, is it time to set up some complicated CI/CD workflow to push it to go live. I don't have these doubts any more ever since I saw how easy it is to deploy stuff to Heroku. Let me show you how you can do that, too.
Building WASM applications in Go 1.11
 wasm  golang  webdev
Some time ago I've first heard about Web Assembly and that it will be the "next big thing" in web application development. Then, once Go 1.11 was released with build support for it included in the language itself, I knew I need to play around with it. Although it took me quite a while, I finally did, so I decided to write down things I found out about it, alongside with a few basic examples.
Full-Text Search in MySQL
 mysql  sql
Some time ago I was facing an interesting issue, which was filtering data based on a part of one of the attributes. It was a classic case of allowing users to get data by entering something in the search box. I figured out that there are more than one ways of completing the task, so I decided to research each of them a bit to have a better understanding of how good those options are.
Tale of two Kubernetes checks
 kubernetes  devops  golang
Kubernetes is a powerful orchestration tool that can make developers' lives much easier, if used and configured correctly. One of the most important things to know about the system in order to manage it correctly is being able to determine if the application is working correctly or if it should be restarted. All of this can be achieved with proper health checks.
My GopherCon UK 2018 talk

They have been available for some time already, but I forgot to share the link! The videos from Gophercon UK 2018, including my _Documenting Go Code with Beautiful Tests_ have been published on Youtube! Enjoy!
Go modules example
 golang  go modules
The latest release of Go, 1.11, was one of the largest in a long time when it comes to functionality. One of the headlines of this version were modules, which were very hyped and hated at the same time, since the community is divided into "modules team" and "dep team". While I feel that dep solves the problems I face on the daily basis, I decided to give the other approach a chance. Let me show you how you can build a small, sample application using "go mod".
Using launchd with Go app
 devops  golang
When I was first introduced to Docker, I was excited to see how much easier this can make developing eg. Java applications. Setting up the whole environment was brought down to a set of simple commands allowing me to spin it up without any fuss. But after spending some time with Go, which compiles to static binary files, I was wondering if I really need Docker containers to run them efficiently? This led me to a little experiment with "launchd".
4-Point Review of GopherCon UK
 golang  conferences
If I wanted to sum up my experience at GopherCon UK 2018, I would probably say something like _awesome_, _unforgettable_ and _amazing_. But those three words would not fully explain everything I saw and felt during that time. It was super-exciting for me, being a first-time speaker at a Go conference. It was also incredibly stressful because even though I'm pretty confident about my English skills, it's something totally different to use it with other people for whom the language is not their native one. Standing on a stage in front of a few hundred people, and butcher the native langue of many (most? half? I have no idea) of them, that was scary. I heard that my jokes got some laughs, so maybe it wasn't that bad. Or they laughed at me, but at this point, it's too late to feel bad about myself. Anyway, I would like to share my thoughts on four of the most important elements of my London experience.
