RetroPlayer – Bringing the Sound of My Youth to iOS

Some projects aren't just about building software—they're about preserving memories, honoring the past, and sharing what shaped you. RetroPlayer is one of those projects for me. Growing up in the 1980s, I spent countless hours in front of a Commodore 64, and later an Amiga, absolutely mesmerized by what these machines could do. The graphics were captivating, the games were endlessly replayable, but what truly captured my imagination was the sound. The SID chip in the C64—with its distinctive three voices—could produce music that seemed impossible for such simple hardware. Composers like Martin Galway, Rob Hubbard, and Ben Daglish weren't...

JavaScript + CSS 3D Wheel of Fortune

Build a fully 3D Wheel of Fortune using nothing but HTML, CSS and JavaScript, with pure geometry and a few clever transforms. Watch it spin in real 3D and see how a handful of divs can create a smooth, random wheel animation.

Еще один самодельный компьютер. Coolsystem — Часть 1

Сегодня мы будем делать еще один восьмибитный компьютер. Да, я еще не наигрался со всеми этими штуками.

Coolsystem - идея компьютера, сочетающего в себе идеи о защищенной среде выполнения (причем в очень-очень специфичном варианте) и способного запускать готовый софт для восьмибитных персоналок 80-х годов. Также он может использоваться для изучения основ схемотехники, своего рода учебный компьютер.

Zeit v1

Zeit began nearly five years ago as a pet project. I needed a lightweight, user-friendly tool to track time, with the added capability to export data for integration with other, mostly home-brewed software used for accounting and invoicing. At the time, I had only a basic set of features in mind and no clear long-term plan for the tool. Little did I know that I seemingly wasn’t alone in my need for a time tracker that stays out of the way and doesn’t come with an attached (paid) cloud service.

Whenever users requested new features or options, I either implemented them myself or accepted...

What's up with FUTO?

Some time ago, I noticed some new organization called FUTO popping up here and there. I’m always interested in seeing new organizations that fund open source popping up, and seeing as they claim several notable projects on their roster, I explored their website with interest and gratitude. I was first confused, and then annoyed by what I found. Confused, because their website is littered with bizzare manifestos,1 and ultimately annoyed because they were playing fast and loose with the term “open source”, using it to describe commercial source-available software.

FUTO eventually clarified their stance on “open source”, first through satire and then somewhat more soberly, perpetuating the self-serving myth that...
