New post cascaded-noise-figure (scheduled 2026-04-29) with four
interactive scenes on noise floor, single-stage NF, the Friis
formula as a block builder, and LNA placement.
Upgrade the three static TCP scenes (data, sliding window, UDP)
to animated packet flow using a shared drawPartialPacket primitive.
Expand IDEAS.md with roughly thirty more post concepts across
electronics, networking, ham radio, microwave, and longer arcs.
Add outbound links to relevant first-mentions across posts:
Fresnel zone, effective Earth radius, atmospheric duct, HRRR,
BJT, common-emitter, TCP/UDP RFCs, slow start, QUIC, Friis,
noise figure, Boltzmann constant. Scrub Unicode arrows and
multiplication symbols out of prose and scene labels.
Filter future-dated posts out of blog/homepage listings and add a
daily 05:05 UTC rebuild so posts go live on their date automatically.
New interactive post on BJT amplification with five canvas scenes
(valve, load line, transfer curve, amplifier in action, gain).
Shared scene.css for future interactive posts. Post is dated
2026-04-23 and will appear in listings once the date arrives.
Also drop IDEAS.md with candidate topics for future posts.
New post "why-signals-bend" with ten hand-rolled canvas scenes
(LOS, Earth curvature, Fresnel, knife-edge and rounded diffraction,
refractivity profile, ray tracing, duct trapping, duct types,
and the real 65 km QTH-to-W5HN/B path with 4/3-Earth bulge).
Also drop QSO/em-dash conventions from prop1 and the
"written by humans" footer line.
