x2q is a personal blog that has been online since 2010 — 16 years of notes on software, Linux, payments, home labs, cooking, and the side projects that keep appearing.
bchunk (binchunker) splits a .bin/.cue CD image into .iso for the data track and .wav files for each audio track. The canonical tool for turning a mixed-mode BIN/CUE into something you can mount or burn.
In 2013, sitting on a balcony in Playitas, Fuerteventura, I built binlist.net as my first ever Go project — a free HTTP API for looking up the issuer of a credit card from its first six digits. It hit 1 million queries/day by 2015. Thirteen years later it's still free, and its commercial sibling iinlist.com is the one we run the business on.
FriendlyElec's CM3588 NAS Kit turns an RK3588 compute module into a 4-bay NVMe home NAS with 2.5 GbE. About 10 W idle. Debian on mainline kernel, ZFS on root, Samba, Tailscale.
fcrackzip is a small, old, command-line tool that recovers passwords on classic-ZipCrypto-encrypted .zip files. Brute-force or dictionary, runs everywhere, still useful in 2026 — with hashcat/john as the modern follow-up when it isn't fast enough.
pdfcrack is a small, single-threaded CPU tool for recovering lost PDF user and owner passwords. Fine for 40-bit RC4 and small dictionary attacks; for 128/256-bit AES PDFs, migrate to pdf2john + hashcat on a GPU.
Twenty-five years of Wi-Fi security in one post: WEP fell in 2001, WPA2 dominated for a decade, KRACK broke it in 2017, WPA3 slowly took over, and by 2027 the attack surface is 6 GHz, management-frame-protection gaps, and social engineering. Defensive guidance included.
Digital post from Danish authorities lands in mit.dk and e-Boks. Nemboks forwards it to the email inbox you actually read — no MitID, no app, no surprises.
The official Squeezebox Spotify plugin has been broken for years. Here's what actually works in 2026: Logitech Media Server + the Spotty plugin, or spotifyd as a Spotify Connect bridge into LMS.
The real hourly price of electricity in Denmark — spot price plus grid tariffs, transmission fees, electricity tax, and 25% VAT. DK1 and DK2, updated daily from Energi Data Service.
A 10-year-old WordPress portfolio rebuilt in Astro: content collections instead of a CMS, Sharp-powered AVIF images, bilingual i18n, and a 70% smaller build.
