I remember these old Czech Čtyřlístek games from my childhood, when they showed up as part of Nesquik cereal promotions. My brother and I used to play them together, and years later I wanted to see whether my son could play them too. That quickly turned into a practical problem: my own machines run Linux or macOS, and even a Windows 11 laptop from work did not run the games reliably.

If you are not Czech, Čtyřlístek is a long-running Czech comics series for kids. It also produced a line of PC CD-ROM games. The whole series has roughly twenty titles, but I focused on three CDs I still had at home:

• Čtyřlístek: Zítra se bude tapetovat (tapetovat, 2001)
• Čtyřlístek: Sami doma (sami, 2003)
• Čtyřlístek: Silák Bobík (silak, 2005)

I run a small home server for the usual homelab things: backups, media, and the occasional "download this now and sort it out later" job. For years, the tool I reached for was JDownloader2. It is powerful, battle-tested, and solves a lot of real problems.

My setup, however, was always awkward. JDownloader2 ran in Docker on the server, and I controlled it through VNC in a browser. It worked, but it made simple tasks feel clumsy. Clipboard sharing was a two-hop problem, resizing the desktop UI inside a browser was never pleasant, mobile use was almost hopeless, and adding links from the CLI meant leaning on MyJDownloader with an online account. I did not want that for a box sitting in my rack.

At some point the shape of the problem became obvious: I did not need a download manager pretending to be a desktop app. I needed a small service that exposes a persistent queue.

So I built DLQ (Download Queue): a headless download-queue daemon and CLI, inspired by the part of JDownloader I actually needed, but designed for Docker, SSH, terminal use, and a home-server workflow. I also wanted a real excuse to learn Go and SvelteKit, so Go became the daemon/CLI language and SvelteKit became the optional web UI.

If you have ever used an "online image converter", you have probably had the same two concerns: privacy and speed. Do I really want to upload personal photos somewhere? And why does a simple conversion take so long?

I built Překresleno.cz to remove that tradeoff. It is a modern image converter that runs entirely in the browser: drop in images, choose an output format, adjust a few practical settings, and download the result individually or as a ZIP. No uploads. No accounts. No server-side image processing.
