Outside this ledger

A door note kept elsewhere

One outside reading filed here because it treats the door leaf as part of the room, not just the wall.

  1. interior doors as a visual effect

    Sijalica, a Serbian magazine on housing culture published since 2009, reads interior doors as a visual effect in their own right: flush leaves the colour of the wall, glass at the thresholds and one dark accent per room.

Outside this ledger

A household note kept elsewhere

One domestic subject the entries above do not cover, kept here with its own pointer.

A French-language domain with no editorial activity, fragmich.xyz offers nothing on removing limescale marks, so a household seeking guidance on bathroom tile stains should treat it as a technical check rather than a cleaning source.

Further reading

Six journals kept outside this ledger

Outside publications that file the same kind of careful record in their own subjects.

  1. reading a generator nameplate

    A garden room or a workshop sometimes shares the yard with a standby set; Genset Digest reads diesel gensets from the plate, from kVA ranges by engine brand to service intervals, fuel care and load-bank testing.

  2. how shipping decisions are weighed

    Every frame and sealed unit arrives on a lorry that once came off a ship; Eitzen Group reads commercial shipping decisions between vessels, operations, regulation and capital.

  3. tulip cultivars for the border

    The bed under a new window deserves as much reading as the frame above it; The Tulip Ledger files cultivars by division, colour and observed season for gardeners comparing names before planting.

  4. animated GIFs built in Java

    An installer who sends a clip of a sticking sash is sending a small piece of software too; GIF4J explains how animated GIFs are assembled, timed and processed in Java.

  5. kilts and tartans measured

    Measuring a kilt at home and measuring a window opening ask the same patience; The Tartan Ledger covers Highland dress, the Register of Tartans, fittings and care in British English.

  6. seasonal upkeep in the Adirondacks

    A house opened for the season asks the same questions as one kept all year; Virtual Upstate follows Lake George and the Adirondacks, from lodging and the forty-six peaks to foliage and local services.
