React Dragging outside the render loop

The whole interactive map is a React app, so the editor started as a regular component. That held until I dragged a control point: every pointermove re-rendered a large subtree (solve constraints, preview SVG, update indicators, update sidebar) and the frame rate fell apart.

On drag, the handlers now mutate MarkerPart.controlPoints directly, then:

  1. Circles and crosses move by CSS translate through DOM refs.
  2. Each editor step is a class with its own imperativeReactComponent, a createRoot plus an .update() method, so only the part that changed is redrawn.
  3. Widgets that still need React (colours, text, icons) read an external reactiveState through useSyncExternalStore, so React re-renders only once that store is notified.
  • Circles: the handle you drag
  • Crosses: where the constraint put it
  • Sidebar: the parts a marker is made of

A page the visitor names in the Embed URL subform

Fetch the page

iframe x-frame-options: deny /api/font-proxy one origin, so the HTML can be read

rust-lang.org refuses to be framed, so a worker on this origin fetches the HTML

Read the stylesheets

<base href="https://rust-lang.org/"> <link href="/static/styles.css"> @import url("fonts.css") @font-face { font-family: "Alfa Slab One"; src: url(/api/font-proxy?url=https%3A%2F%2Frust-lang.org%2F…%2FAlfaSlabOne.woff2)

The browser follows every link and @import. It makes each src absolute and routes it through the proxy, since webfont loads are CORS-checked too

document.fonts.add()

cubic-bezier(0.75, 0.25, 0.2, 0.2) gives the orbit a push and lets it settle. Kept for every turn it stutters at each restart, so at 750ms the script swaps the timing function for linear at the point the curve has already reached. The seam goes, the first turn keeps its kick

One element, two backgrounds. The gradient is painted on the border box and the field's own colour covers the padding box over it, so the only part left showing is the border. Three custom properties move it: where the arc starts, how much of the turn is coloured, and the colour. @property types them as angles and a colour, which is what makes them animatable at all

    Inside transformPath, for both frames 
    const mapWidthAbsolute = (x: number) => ((x - fromViewBox.x) / fromViewBox.width) * toViewBox.width + toViewBox.x;
    Scales x from the viewBox width to the box's width and adds the box's left. y likewise.

GNU social event bus

GNU social · Event Dispatch
Medium
PHP, Symfony
Year
Notes
GNU social is a federated social network server. Its plugins never call each other: a plugin listens for an event by naming a method after it, and the first one to return stop has the job. Switch ImageEncoder off and no other plugin claims the JPEG, so the template draws a plain link. ImageEncoder shows a GIF too, then asks for its thumbnail with a second event, FileResizerAvailable. That one has two takers at the same priority. VideoEncoder asked for image/gif by name, so it goes first and keeps the GIF moving. Switch it off and ImageEncoder makes a still.

Each listener is [Module, 'onViewAttachment'], in the order the modules were found ImageEncoder's view asks for the GIF's thumbnail, and getOrCreate raises this. Each listener is [Module, 'onFileResizerAvailable']

  10. gnusocial-alice to nginx: nginx.depends_on
  11. nginx: server_name alice.localhost alice.fediverse
One shot
The installer has restart: no. Its lane stops at exit 0, and only then does the app start.
Run again
If the language table has rows, the script only seeds the admin again and exits 0, so up is safe to repeat.
Its name
CONFIG_DOMAIN=alice.localhost tells the server who it is on the network. Its admin is admin@alice.localhost.
v2
The v2 server has the same pair, gated on mariadb instead of Postgres.

Notes
A library object stores its size once, in centimetres. On each save, database triggers wrote that size out in centimetres, metres, inches and feet, so a search for 5ft3in or 1.6m found the same table. The triggers lived five weeks on a branch before Ruby callbacks replaced them.
One table's size, split, converted and searched

The table's size is stored as 160x80x74, in centimetres. When the row is saved, triggers split it on x, write each piece in centimetres, metres, inches and feet, and store every form in the text that search reads.

The walkthrough types in these fields. They don't take your own typing.

Each dimension in six units Each row of split_sizes goes through six SELECTs, one per unit, and GROUP_CONCAT joins a unit's pieces with ' by '. Centimetres and metres keep two significant figures. Inches round to the whole inch.
Unit 16080182
Size (centimeters) ROUND(cm, 1 - FLOOR(LOG10(cm))) 160cm 80cm 180cm
Size (meters) ROUND(cm / 100, 3 - FLOOR(LOG10(cm))) 1.6m 0.8m 1.8m
Size (inches) ROUND(cm / 2.54) 63" 31" 72"
Size (inches) ROUND(cm / 2.54) 63in 31in 72in
Size (feet-inches) FLOOR(in / 12) + carry, ROUND(in MOD 12) if not 0 5'3" 2'7" 6'
Size (feet-inches) FLOOR(in / 12) + carry, ROUND(in MOD 12) if not 0 5ft3in 2ft7in 6ft

182cm is 71.65in, or 5ft and 11.65in. The 11.65in rounds to 12, so it carries and prints as 6ft, not 5ft12in.

The shipped SQL did not round, so 182.5 printed as 182.5cm and 1.825m. It added a foot from six leftover inches, so 80cm read 3ft7in, and it wrote whole feet as 6ft0in. The rules above fix all three. When rounding changes a size, the exact centimetres and metres are kept too, so a search for 182cm still finds it.

Size
Glued onto the name before the lookup: 'tiny' on an int looks up tinyint, which has no portable form, so smallint
Null
'not null' => true is inverted into 'nullable' => false; a field that says nothing is nullable
Width
char is the same string type as varchar, with 'fixed' => true
Serial
An integer plus GENERATOR_TYPE_AUTO on the class

Each 'description' becomes a column comment: the documentation lands in the database

Emacs Lisp, tree-sitter

Notes
An Emacs major mode for web templates such as Astro and Vue, where one file mixes markup, TypeScript and styles. Each language gets its own tree-sitter parser over its part of the file, and highlighting and indenting work across the whole file.
Notes
  1. web-ts-mode is an Emacs major mode for files that mix languages. This Astro component from the CV has TypeScript in its frontmatter, markup with expressions in it, and a SCSS style block.
  2. The astro parser reads the whole file, markup included. The TypeScript and the SCSS each get a parser of their own that sees only its range. Each dashed box is one range, drawn inside the range that holds it.
  3. The site's build colours the code with a small lexer that follows the mode's faces. The ranges are the ones Emacs 31.1 hands each parser for this file.

*
* It is a child of #main rather than of the sheet, because the margin it stands in belongs to
* the desk and not to the paper. Absolutely positioned in the left margin column of the grid
* row its sheet sits in, it takes that row as its containing block, which is what gives the
* numeral the sheet's own height to stick along. The row is the number: there is one folio
* per sheet and they run in page order. Both ends of the row are named, since a grid line an

Notes
  1. Each language needs a tree-sitter grammar, and completion and error checks need a language server on PATH. M-x web-ts-doctor lists both.
  2. A missing grammar shows up as a line here. When a file opens, the mode leaves that language unhighlighted and carries on.

The crash led through OpenCascade 7.9.3's point classifier to a wrong-code bug in GCC 16, where interprocedural constant propagation redirected a recursive call to a clone specialised for a different dynamic type, so the program ran the wrong virtual method. Bisected GCC to two January 2026 changes, reduced the miscompile to a C++ testcase of a few dozen lines, wrote the fix and a regression test, and bootstrapped and regtested GCC. The IPA maintainer reviewed it and pushed it to master the same day, with a GCC 16 backport planned. Around it, a nixpkgs workaround builds OpenCascade with `-fno-ipa-cp-clone` and fails the build if the miscompile returns, an OpenCascade issue asks for a 7.9 backport of its fix, and a FreeCAD PR backports OpenCascade 8 support to the 1.1 branch

inauman/libfprint#1 elanpress: support 04f3:0c6e (inauman/libfprint), opens in a new tab

Added the ELAN 04f3:0c6e press sensor of the ASUS ROG Flow X13 to libfprint's new elanpress driver. On master it sits under the swipe-only elan driver, where enrolment fails with a protocol error and verify never matches. Two follow-up fixes keep a background frame captured with the finger down from becoming a touch, and keep more distinct probe frames per touch. Scored offline on a recorded session, 15 held-out touches of the enrolled finger matched at 0.848 to 0.954 and 47 touches from other fingers and another person stayed at 0.294 to 0.761, so no false accepts. inauman took all three commits into the branch behind libfprint!654 on 2026-10-20 and closed this one, so they now wait on upstream review there

gcc.gnu.org#127917 ipa-cp: Check polymorphic contexts before redirecting to a clone [PR127917] (gcc.gnu.org), opens in a new tab

FreeCAD booleans crashed on NixOS because OpenCascade's bounding box tree walk ran the line selector's Accept on the point selector. GCC 16's IPA-CP had redirected a recursive call to a clone made for a different polymorphic context. Bisected it with prebuilt snapshots to two January changes, reduced it to two short C++ testcases, wrote the fix and a regression test, and bootstrapped and regtested on x86_64. The IPA maintainer reviewed it and pushed it to master the same day, with a GCC 16 backport to follow (bug 127917). A nixpkgs PR builds OCCT with -fno-ipa-cp-clone and adds an install check for the miscompile, an OpenCascade issue asks for the OCCT 8 fix to be backported to 7.9, and a FreeCAD PR backports its OpenCascade 8 support to the 1.1 branch

inauman/libfprint#4 elanpress: reject non-finite and out-of-range FP_ELANPRESS_* values (inauman/libfprint), opens in a new tab

Every FP_ELANPRESS_* setting comes from the environment, and some bad values broke the driver instead of being refused: a nan quality gate rejected nothing, a huge FP_ELANPRESS_NORM_WIN hit an undefined int cast, and a tiny FP_ELANPRESS_ROT_STEP overflowed the count of rotated probes. Five commits make the shared parser ignore values that are not finite, bound the integer, rotation and overlap settings, and log what it ignored or clamped. Each has a unit test that fails without it. Stacked on !3, awaiting review

inauman/libfprint#3 elanpress: don't let rejected frames set the relative contrast bar (inauman/libfprint), opens in a new tab

The quality gate drops frames under half the best contrast of a touch, but it took that best from every frame, including ones the absolute gates reject. A frame from a finger landing or lifting is mostly ridge edges and can have twice the contrast of a full press, and on 0c6e one such frame put the bar above all eight full-contact frames of its touch. The best now comes only from frames that pass the absolute gates, with a unit test that feeds that touch. Replaying 116 touches from daily use, six keep more probe frames and the rest are unchanged.

Five commits rework that loop: 16-bit layers so every sum is one multiply-add, summed-area tables for the single-layer sums, a half-resolution search kept to the best quarter-resolution peaks, SSE2 intrinsics, and AVX2 and AVX-512 copies picked at run time. Matching 3 probe frames against 80 images on one core went from 2.1 s to 0.17 s. Every commit but the peak search gives the same scores on 240 genuine and 3136 impostor matches. Awaiting review

torvalds/linux drm/client: Keep larger modes in connector->modes on fbdev hotplug (torvalds/linux), opens in a new tab

On an ASUS ROG Flow X13 booted with video=eDP-1:1920x1200@60, an HDMI hotplug made fbdev reprobe every connector with its 1920x1200 framebuffer as the limit. The 3840x2400 eDP panel lost its native mode from connector->modes, and after suspend/resume amdgpu drove it at 1920x1200 with the image squeezed into the top-left corner. Patch 1 makes drm_client_modeset_probe() probe with the device's mode size limits, as fbdev's first probe already does, and moves the framebuffer size check into the fbdev mode pickers. Patch 2 adds KUnit tests. v2 also checks the size of the CRTC's current mode before the firmware config falls back to it, which Sashiko found. With only this series applied, 255 of 255 resumes kept the native timing, against 28 of 29 wrong without it. Ville Syrjälä said on 2026-10-16 the approach should be fine but gave no tag, so it is still under review

torvalds/linux drm/amd/display: Keep eDP native timing after resume with video= (torvalds/linux), opens in a new tab

Two patches on amd-gfx. After an HDMI hotplug and a suspend/resume, a 3840x2400 eDP panel booted with a video= mode came back squeezed into the top-left corner. The fbdev reprobe had dropped the native mode and amdgpu scaled onto the first one left. On eDP and LVDS the fix falls back to a listed mode of the native size, or else to the encoder's native mode, with KUnit tests that fail without it. On 7.2.8, 103 of 103 resumes were wrong before and 1363 of 1363 right after. v2 is rebased onto amd-staging-drm-next, as Tom Chung at AMD asked. A second series on dri-devel, drm/client: Keep larger modes in connector->modes on fbdev hotplug, fixes the same bug for every driver. Both are under review

peteonrails/voxtype#903 fix(hotkey): wait in poll() between events instead of a 5 ms sleep (peteonrails/voxtype), opens in a new tab

The evdev listener slept 5 ms between passes over its devices, so an idle daemon woke about 200 times a second to find nothing to read. It now blocks in poll() on the keyboard fds and the inotify watch, with a 100 ms timeout so the stop signal and the device checks still run, and handles key events as they arrive. On my laptop an idle daemon went from about 229 wakeups a second to about 42. A draft, waiting on CI approval and review

upower/power-profiles-daemon#242 amdgpu_panel_power: Allow configuring the levels in the settings file (upower/power-profiles-daemon), opens in a new tab

The action picks the panel's ABM level from the profile and the battery charge, with power-saver at 0 above 50% and balanced at 1 below 30%, and nobody could change it: one user wanted the saving at any charge (#185), others found level 3 too strong (#159). Adds a load_settings vfunc so an action reads its own group from power-profiles-daemon.conf, with PowerSaverLevel, BalancedLevel and PerformanceLevel keys that apply on battery at any charge; unset keys keep today's steps, and unknown groups, keys or values out of 0 to 4 get a warning. A first commit fixes a leak already on main, where both error returns in set_panel_power() skipped freeing the drm device list. Measured on an ASUS ROG Flow X13: level 4 saves 0.4 to 0.6 W of about 10.4 W. Stacked on !241

upower/power-profiles-daemon#241 Read the daemon options from power-profiles-daemon.conf (upower/power-profiles-daemon), opens in a new tab

Blocking a driver or an action meant overriding ExecStart in a systemd drop-in, which breaks when a distribution installs the daemon elsewhere or changes the unit. The daemon now looks for power-profiles-daemon.conf and a .conf.d/ directory in /etc, /run, /usr/local/lib and /usr/lib, in systemd's order and with systemd's rules: a later key replaces an earlier one, a drop-in of the same name higher up masks the lower one, a link to /dev/null masks a file, and files are opened without blocking and read rather than mapped so a FIFO or a truncated file cannot stop startup. The [Daemon] group takes BlockDrivers and BlockActions, and unknown keys, groups and names get a warning. A second commit makes SetActionEnabled refuse to turn on a blocked action instead of reporting success

outfoxxed/hy3#344 fix: switch tabs on touchscreen taps (outfoxxed/hy3), opens in a new tab

Tapping a tab on a touchscreen did not switch to it, and the tab bar could disappear until a new window opened, because the click handler only listened to mouse buttons, which Hyprland never raises for touch. Moves the lookup into Hy3Layout::tabAt() and calls it from an input.touch.down listener too; a tap on a tab cancels its down, motion and up events so the client underneath never sees the touch, and the listener repeats Hyprland's own checks for the locked session, kill mode, workspace swipes and covering surfaces. Tested in a VM with a virtual touchscreen and earlier on a real one

Unloading hy3 with a tab group open crashed Hyprland on the next animation tick, which any reload that changes the plugin path triggers, such as a NixOS switch that rebuilds hy3. Hyprland calls PLUGIN_EXIT first and removes the layouts after, and removing them put fading tab groups back on a list whose tick listener was already gone. Removes the layout at the start of PLUGIN_EXIT so the clears free what is left, and drops the tab pass element from the render pass as hyprbars does. Tested in a VM through an unload, a reload and six swaps between builds

Letting go of push-to-talk a moment early cut the last word, and Whisper dropped it or guessed. With audio.stop_tail_ms set, the daemon keeps capturing after the stop until the last 160 ms are quiet, for at most that long; a clean release stops at once. Quiet is three times the recording's noise floor, taken as its 10th-percentile frame and capped where quiet speech starts, so the bar follows the mic and the room.

The modifier guard opened every /dev/input/event* node on each paste and closed them all afterwards, and each close waits for a kernel RCU grace period of 10 to 35 ms, so the guard alone added a few hundred milliseconds before every output (#543). Keyboards now stay open in a process-wide cache; each call still lists /dev/input and opens only nodes that are new or re-created, told apart by inode, so hotplug keeps working, and any close runs on a background thread off the output path

withastro/compiler-rs#200 fix(astro2tsx): print processing instructions as comments (withastro/compiler-rs), opens in a new tab

With the Biome lexer fix, <?xml version="1.0"?> parses as an HtmlProcessingInstruction in Astro files, and astro2tsx copied it into the TSX verbatim, where TypeScript cannot parse <?. It now prints each instruction as a JSX comment through the path HTML comments use, at the root before the doctype and inside elements. New snapshot fixtures and a type-check test cover it, and astro check on the repro went from 7 errors to 0. Closes #199. Closed in favour of #205, which the maintainer merged with the same astro2tsx change

FreeCAD/FreeCAD#33629 [Backport releases/FreeCAD-1-1] Adapt FreeCAD to OpenCascade 8 (FreeCAD/FreeCAD), opens in a new tab

Backported the OpenCascade 8 support from main to the 1.1 release branch, 15 commits plus the -Werror guards and the TechDraw fix, so distros shipping FreeCAD 1.1 could build against OCCT 8 and sidestep the GCC 16 miscompile of 7.9.3. Tested with FreeCADCmd -t 0 on OCCT 8.0.1 and 7.9.3, 1666 tests with the same results as 1.1.4, and the cube minus cylinder recomputes instead of crashing. The maintainers closed it, since the 1.1 branch gets no further releases and 26.3 is the first version to support OCCT 8

peteonrails/voxtype#829 fix(output): keep the text on the clipboard when the modifier guard skips a paste (peteonrails/voxtype), opens in a new tab

In paste mode the output chain held only the paste method. When a modifier was still down past modifier_release_timeout_ms, the guard skipped the paste and nothing else ran, so the dictation was lost although the notification said it was copied to the clipboard. Hit with Right Ctrl as the hotkey. Added wl-copy after the paste, as type mode already has, with a test that the chain keeps a method that survives the keystroke filter. Closed as a duplicate of #588 and #654

git/git rebase: add --[no-]edit to --continue (git/git), opens in a new tab

Added git rebase --continue --no-edit and rebase.noEdit to skip opening $EDITOR after resolving conflicts, with --edit to override the config for a single continue. Junio Hamano and Phillip Wood worried that rebase.noEdit would also skip the editor after an edit or reword stop, and asked for tests beyond the conflict case. Dropped without a v2

Bumped gtk4 to 4.22.5 for the upstream munmap() fix in the Wayland dmabuf format table, which took down any GTK4 client on Hyprland whenever a monitor was plugged in. Traced from a coredump and first sent as a backported patch; the reviewer asked for the bump once 4.22.5 was tagged. Closed as a duplicate of #559510, the GNOME 51 update on staging, which takes gtk4 to 4.24.0
