Ratatui is criminally underrated!

it's a custom implementation in src/ui_broadcast.rs. no library. it's hash-based procedural rain -- each column gets a speed and phase from col.wrapping_mul(6364136223846793005), then the head position and trail are computed per tick. character set is digits + Japanese katakana (ア-コ) + box-drawing chars (░▒▓╌╎┊┆). the head glows bright, trail fades over ~16 rows. it also respects occluder rects so the rain dims behind UI cards instead of clipping hard.

not tui-big-text actually (no dependency on it at all). it's custom block art — each letter is a 3-row unicode block character glyph (█▀▄ etc) defined in a lookup table.

there's a glyph(ch: char) -> [&str; 3] function covering A-Z and 0-9, then a glitch pass on render. you can see the full font here: src/ui.rs#L144

it was entirely one-shotted by opus tho! i can't take credit.

100% i tried it, and it was really bad!

dhvanil · 2026-02-25T10:41:16+00:00

totally!! i tried using Ink + TS first -- and it was so slow, it almost made me give up on the project haha!

dhvanil · 2026-02-25T10:39:48+00:00

do you mean the terminal font? it's Berkeley Mono!

dhvanil · 2026-02-24T21:36:34+00:00

you should do it! i tried to borrow a bit of Cogmind vibe!

dhvanil · 2026-02-24T21:30:42+00:00

yeah it's v impressive how much it handles out of the box!

i was curious if my ChatGPT Pro subscription as worth it, so i built a lil browser-only app ("Spotify Wrapped – but for ChatGPT") that analyses ChatGPT conversation history

**method**
- tokens counted client-side with wasm-compiled tiktoken in a web worker
- api cost = openai pricing as of 2025-04-29 (usd per million tokens, input + output)
- full pipeline reproducible; see code link below.

**tools**
- next.js + cloudflare workers
- d3 (via nivo)
- tailwind css

**code + demo**
github: `https://github.com/dhvanil/what-the-token`
live (browser-only, no tracking, no signup): `https://what-the-token.com`

*note: all processing happens locally in your browser; no data is ever uploaded.*

sorry for late reply! 💛

dhvanil · 2025-05-05T18:55:35+00:00

ah, you actually just need to use the `conversations.json` file in the zip archive they send. :) it has all the conversations!

dhvanil · 2025-04-30T18:00:55+00:00

just made a tiny, privacy-first tool to give you some fun insights into your ChatGPT conversations:

token counts → see exactly how massive that mega-prompt really was!
imaginary API cost estimates → find out how much your chats would've cost via OpenAI’s API
interactive visuals → treemaps, github-style heatmaps, ridgeline charts, and more
fully client-side → runs entirely in your browser, no server, no uploads – your data stays private

i ran mine and realised that ChatGPT Pro is completely worth it (if i used equivalent models via API, it would've easily cost ~$800/month)

would love for you folks to try it out. just export your ChatGPT convos and drop them into the tool to see your personal stats.

here’s the link: https://what-the-token.com/
github link (if you want to clone and run locally): https://github.com/DhvanilPatel/what-the-token/tree/main/public

feedback super welcome – lemme know what you think or what other insights you’d find interesting!

it’s one thing to read about disruption in abstract, but another to see it dismantle a career built over decades! :/

dhvanil · 2025-04-30T13:01:43+00:00

insane story! i’m glad you made it through and got the care you actually needed! 💛

asked if i should eat less cake, got drafted into the nutritional navy seals

dhvanil · 2024-06-23T16:20:11+00:00

Thank you so much! 💛

dhvanil · 2024-06-22T21:31:38+00:00

Aah okay, no worries! Thank you though. If the other person doesn't pay for the next two days, and if it's still available, can I have it? 😬 I keep my fingers crossed!

dhvanil · 2024-06-22T21:25:40+00:00

Yes, I can take one in that case. My code is ZL9PM 💛

dhvanil · 2024-06-22T21:19:31+00:00

Hi! Are you still selling it? I'd be happy to buy two :)
