QEMU on Wayland: mouse & scaling fixes
Why the QEMU guest mouse drifts or hits an invisible dead zone on Wayland/KDE, why the display is blurry under fractional display scaling, and patches adding pixel-perfect integer scaling.
QEMU freezes when printing to a parallel port
A guest writing to LPT1 can stop the entire VM — the monitor goes silent and SIGTERM is ignored — because one chardev write spins on the vCPU thread holding the BQL. Root cause, reproducer, and a non-blocking fix.
A network for Windows 98, Mac OS 9 and DOS
An Alpine Linux appliance that gives obsolete computers a usable network of their own: DHCP, DNS and NAT, guest SMB1 shares Windows 98 can open, AFP for classic Mac OS, a printer that writes PDF files, and mTCP NetDrive for DOS.
VNC viewer for games
An Android VNC client shaped around playing games rather than administering machines: large always-on touch buttons in the screen margins, latching modifiers, and a layout you regenerate from a JSON profile.

Scream Audio Monitoring
A complete guide to building an integrated audio monitoring system using the Scream protocol over UDP multicast on a LAN.
Scream sender for PipeWire
A PipeWire module that creates a virtual audio sink and transmits everything played to it over UDP as raw PCM — the Linux counterpart of the Windows Scream driver.
screamplay
A command-line player that streams WAV, FLAC, OGG and MP3 to any Scream receiver over the network, resampling odd rates to 48 kHz and pacing packets so the stream does not drift.
Screamdroid
An Android receiver for Scream network audio over UDP: the PC sends its sound over Wi-Fi and the phone plays it through headphones already paired with it, so a desktop with no Bluetooth borrows the phone's. An incoming call silences the stream by itself.
Piper TTS for Ren'Py
Replace Ren'Py's robotic espeak voice with natural-sounding Piper TTS on Linux — free, local, no internet required.
