Whether we know it or not, we build things based on the work done before us. This is true in every aspect of life, and programming is no different. Every few weeks, we (at Niteo) have a developer session where we (developers at Niteo) talk about new things we learned, cool libraries/tools we discovered, etc.Last […]

At Niteo, we are using nix-shell to build isolated development and production environments. We deploy production as a Docker image on Heroku. Recently, I’ve noticed that Pareto Security dashboard app deployments have been very slow. Almost 10 minutes, even more on a busy afternoon. Most of the time was spent in copying files around, as […]

Sprints are back! featured image

Back in early 2010’s, “sprints” were how I lived. Week-long events, in random places around the World, hacking on open source. From offices in European cities, to lake sides, castles and saunas. It’s where I met some of my best friends, where I got business for Niteo’s agency side. It’s where I learned more than […]

Last year we decided to replace our Ubuntu servers with NixOS. We were still on Ubuntu 14.04, so we also had to upgrade all the services and tools, including PHP, MySQL, HAProxy, etc. As you can imagine, this was a lot of work, and you might be asking yourself, “why didn’t you just upgrade Ubuntu?” […]

Concurrency in Go is an extensive topic, and we won’t cover all the things in this post. There are tons of articles and several books that cover concurrency in depth. The goal of this post is to cover topics between basic and advance. We’ll cover the usage of sync.WaitGroup and channels. Those two things combined […]

Lowering H12 errors on Heroku featured image

This post will briefly discuss H12 errors on Heroku, more commonly known as request timeouts, how we tackled them, and how we fixed them. Before we start, let’s establish some context. We have an app that’s a hub for ~600 servers. A few times per day, each server creates a request to the app, ensuring […]

Staging like it’s 2020 featured image

Last year, we wrote a blog post on how we use Heroku’s Review Apps to create staging apps for every Pull Request submitted to a project’s repository. These apps are created and deployed automatically, completely isolated from the production environment, and contain the changes from the Pull Request. This allows every stakeholder to see how […]

I’ve been a Python dev for almost 15 years now and I’ve recently completely overhauled how I keep my development tools and dependencies in check. I’m so happy with my new setup that I couldn’t wait to share it with fellow geeks! Some background I used to use Homebrew to install tools such as pyenv […]
