I started SPT in May as an experiment with Chinese open-weight models: first DeepSeek 4 Flash, then DeepSeek 4.1 Flash. I also tried different coding harnesses, including Codex and Pi.

A public transport app gave me something useful to build while comparing them: find a nearby stop in Sofia, check when the tram is coming, and work out which connections to take. Five months later, it also works in Zürich.

A few weeks ago we had to implement a CRUD form in Rails for a model utilizing Rails’ single table inheritance associations.

For the past few weeks, I have been working on integrating Docker and Jenkins in order to improve the continuous integration workflow of a project I work on.

In my previous blog post, I gave a high-level overview of the workflow when producing a live webcast for an event. In this post I will discuss in detail what hardware is necessary to produce a high-quality live streaming with one external camera, as well as how to configure the software encoder to stream to a media server.

Producing a live webcast for an upcoming event is a complex job, which involves a few important tasks. This post aims to briefly cover all of them, as well as highlight the most common mistakes event organizers make.

I have been following the development of Docker for the past few months. Docker is an open-source project to easily create lightweight, portable, self-sufficient containers from any application. A few great tutorials on how to use it already came up, so I decided to give it a try for a side project and share my experiences.

Yesterday I spent a few hours working on adding multiple file upload capabilities to the administrative panel of a website I am working on. The administrative panel of the website is built using RailsAdmin. RailsAdmin is a Rails engine that provides an easy-to-use interface for managing your data.
