Code reviews are a huge part of our day-to-day job and over the years I realized it takes time to learn how to write them in a way that is helpful and also encouraging. As developers, we tend to be very direct when we communicate, but when it is not done face to face or when we work on a remote team and do not know each other well, very direct communication can make an impression of being rude or harsh. Also sometimes the feedback is just too vague or…

In recent years, the rise of synthetic voice technology has opened up new possibilities for a variety of voice-based applications. Whether it's creating personalized voice assistants, enhancing accessibility tools, or developing unique AI-driven experiences, the potential is vast. But how easy is it to create a custom voice AI model that runs locally on your computer, without relying on cloud services? Applio offers a powerful, open-source solution making training and using a custom voice model accessible to everyone—from developers to creative teams. Unlike cloud-based alternatives, Applio does not require an…

In recent years, large language models (LLMs) have revolutionized the way we interact with technology. From enhancing productivity to enabling creative applications, their potential is vast. How challenging is it to run a powerful LLM directly on your PC or laptop? LM Studio is a user-friendly app that allows you to easily manage and run LLMs on your computer. It offers a streamlined interface, making it accessible even for those new to machine learning. In this video tutorial, Miloš Švaňa walks users through how to choose, download, and run an…

AI Developer Tools With the rapid advancements in large language models (LLMs) over the past few years, we’ve seen a surge in AI-powered developer tools. Since code is essentially text, it’s an ideal use case for LLMs. While there are many tools available to assist with software development, let’s focus on the most impactful ones: code completion and code manipulation tools. The most well-known tool in this space is GitHub Copilot, which gained immense popularity as one of the first to hit the market. However, there are now several new…

Applications powered by large language models (LLMs) need to be more than merely functional—they need to be scalable, reliable, and capable of continuous improvement over time. To make this happen, you need tools that allow you to trace and fine-tune your app's performance to identify inefficiencies, diagnose issues, and improve response quality. This is where LangSmith comes into play: a tool built for developers working with LLMs who need insight into how their AI models behave in production environments. LangSmith can be a game changer for AI developers. LangSmith gives…

New frameworks and tools are constantly emerging, each promising to make our lives easier and our applications faster. But every so often, a framework comes along that doesn’t just promise incremental improvements—it redefines the game. Qwik is one such framework: built by performance nerds, for performance nerds.  Qwik introduces novel architecture that eliminates the need for the traditional UI hydration process, a step that often bogs down web apps with unnecessary overhead. Instead of rehydrating the entire UI on the client side, Qwik only activates the parts of the application…

Me and many of my colleagues at profiq use Notion for note-taking and work organization. Our workspaces contain a lot of knowledge about our work, plans, or the articles or books we read. At some point, a thought came to my mind: couldn’t we use all this knowledge to come up with project ideas suited to our skills and interests?
