Scalac's blog

Machine Learning models are great and powerful. In this article, we will revisit a regular optimization problem using an example of a binary classification. We will show a way to create more robust and stable models that use features that are more meaningful to humans.

You have probably encountered this problem while working with SBT and bigger projects. I’m talking about compilation times and test execution times, in other words, having to wait instead of working. Imagine working with a build tool that rebuilds only what is necessary, using a distributed cache, so if module A is built by one […]

There are plenty of frameworks you can base your application on in Scala, and every one offers a different flavor of the language with its own set of patterns and solutions. In this blog post, you will learn how to structure a command-line application using ZIO.

With the growing number of mobile devices on the market, the problem of how to keep up with the needs of users and provide them with high-quality software is also increasing. To meet these demands, we need a specific approach. That's why testing for mobile apps is an entirely different topic than web application testing.

Main goal in this article is to show you the OSI model and explain how data flows in a network. Then I will go through the differences between the OSI model and TCP/IP. At the end of the article, I will also mention a few protocols used in networks.

You must have been asleep (for a few years at least) because Angular 7.x is already here and you’re still stuck on AngularJS. Or maybe it’s just that your codebase is so damn large you can’t face wasting years of your life rewriting it all at once? Fear not! It’s not that bad. You can (and should!) upgrade to Angular 7 step by step, or you can do it while leaving your old code in place, working with the latest Angular shipping new features.

During the Cryptonomic NYC Hackathon we decided to create a Google-like translator between Michelson and Micheline; two formats of source files used in Tezos software development.

We live in an era of cryptocurrencies, and there’s no escaping it. It’s already happening, and if there’s one thing that represents well what’s going to happen next, it’s blockchain. That’s why during the Cryptonomic NYC Hackathon we decided to try and visualize tezos transactions on the frontend side.

All of us are eager to start writing real-world applications using ZIO (Scala library). But ZIO is still quite new, and its ecosystem is still incomplete. So while we wait for ZIO-HTTP and ZIO-JDBC (or whatever else comes in the future) to happen, we will have to end up integrating ZIO with other frameworks that can communicate with the outside world. In this article, I want to explore what this kind of integration might look like for two of the most popular libraries - Slick and Akka HTTP.

If you’re testing web apps then you need to know what the purpose of HTTP protocol is and how it works. Actually, in my first project I lacked this knowledge. However, since then I’ve realised how important it is and that’s the reason I want to share it with you. In this article I will […]
