Vue 3.6's 13th release candidate: seven of eight fixes live in the Vapor compiler
Almost everything in 3.6.0-rc.13 points at compiler-vapor, plus one change that restores the 200ms default delay for async components. The first says Vapor is still catching up on semantics; the second says defaults are API.
Turning an AI search into a tree you can page through
Visualising a search is not mainly about drawing the tree. The data has to be real, the panel must not shove the board around, and it must load only for people who click the button.
Base and unit conversion: temperature is the only non-linear one
Converting between bases 2 and 36 needs BigInt to avoid silent precision loss. Across ten unit categories nine are linear ratios, while temperature is affine, and a single multiplier is always wrong.
Color and contrast: relative luminance is not an average
Converting between notations is just the entry point. The real trap is WCAG contrast, which needs gamma decoding before weighting, and deciding between black and white text, which is not a brightness threshold.
Hash and checksum: why CRC32 and MD5 have to be written by hand
The browser only offers the SHA family, and only in a secure context. CRC32 and MD5 are not in Web Crypto. Along the way: large files should not be read into memory whole, and checksums should not be compared by eye.
Regex Lab: hits, groups, replacement preview, and the zero-width trap
A regex tester has to do three things well: show where matches land and what each group captured, preview the replacement, and never hang on a zero-width match.
JSON Studio: format, validate and diff in one page
Built from the habit of writing throwaway commands to clean up JSON. It formats, minifies, sorts, pinpoints parse errors by line and column, and diffs two documents — all in the browser.
Pushing first-load JS to zero with Astro islands
From "async import" to "hydrate on demand" — what each of the three lazy-loading layers actually solves, with the code that runs on this site.
A theme-switch ripple with the View Transitions API
A circle growing from the click point reveals the new theme. The radius must reach the farthest corner, and the custom properties must be cleaned up or they leak into the next switch.
No client:only for app pages: a static shell plus an explicit mount
Game and tool pages are a shell plus createApp, not client:only. I own the loading, ready and error states, and the retry button actually works.
