What it does
QR encodes data in black-and-white squares — right for a 1994 camera. Cameras changed; the squares didn't. So we spent the slack on looks. TLcube splits a hexagonal cell into three rhombic faces and encodes data in the rank order of their brightness, not in absolute values — shift exposure, gamma or contrast and the answer survives. Four silhouettes, an optional fallback QR, browser generator and scanner. Free to use, like QR. No licence fee, no per-scan cost. Apache-2.0.
육각 셀을 마름모 3면으로 나누고, 세 면의 상대 휘도 순서에 데이터를 싣는 오픈 3D 바코드. 스펙과 레퍼런스 구현은 Apache-2.0 으로 공개돼 있습니다. True 3D H — Y 그룹의 실제 큐브 확장.
포스터·패키지·명함… QR이 안 들어가는 데가 없는데, 공들인 디자인 위에 마지막으로 흑백 네모를 얹는 건 늘 아쉬웠어요. 그런데 QR이 그렇게 생긴 데는 이유가 있습니다 — 1994년의 카메라와 연산으로 «어떻게든 읽히게» 만든 결과 거든요. 그 제약이 지금은 많이 풀렸습니다. 카메라도 연산도 넉넉해졌죠. 그래서 인식 성능만 더 쫓는 대신 눈에 들어오는 쪽 으로 한번 만들어 봤어요. QR을 대체하려는 게 아니라, 옆자리를 하나 만드는 겁니다. 결과물은 3D 바코드 — 평면에 인쇄되지만 눈에는 입체로 읽힙니다. 어디에 얹을지에 따라 고르면 됩니다. 평면 타입은 모두 같은 데이터 계약을 공유하고 실루엣만 달라요. True 3D H는 Y 그룹의 실제 큐브 확장으로, 포맷이 따로 있어요. 아래 코드에는 전부 https://tl.estre.so 가 들어 있어요. 실제 큐브의 면 1…6개에 서로 다른 데이터를 싣는 별도 포맷이에요. 생성기에서 회전 영상(MP4)·종이 도안·3D 인쇄 파일도 받을 수 있어요. 3시 방향 노치가 실루엣만으로 방향과 타입을 확정합니다. C0~C3는 근접 스캔 전용이며, C1 이상은 가까이 대거나 확대해서 읽어야 해요. 순 페이로드는 ECC-M 기준이에요. H를 포함한 모든 타입에 폴백 QR 을 함께 인쇄할 수 있어서, TL 코드를 못 읽는 환경에서도 최소한의 경로가 남습니다. H는 기본으로 좌상단 모서리에 QR을…from tl.estre.so

In the "Libre Barcode Project" discussion yesterday, 1bpp asked: "Is anyone willing to sacrifice their sanity for the sake of implementing a QR renderer as TTF hinting code?" Yes. I had some tokens to burn and was curious... turns out, it's possible. This was put together by a mix of Gemini, GPT, and Claude (depending on which usage limits kept running out).

Talanoa▲340Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

Clipto MCP▲655Hey HN, We recently built Clipto. It’s a tool that lets you search over terabytes of video, audio, and images on your computer, without relying on the cloud. Motivation: we probably all had this similar experience, we know a moment exists in a video or audio, but finding it takes hours scrubbing the timeline. You can send all the media to process in the cloud, but it’s slow, expensive and raises privacy concerns. So we decided to build our own on-device media search engine. How it works (high level): 1. We ingest video, audio, image; normalize formats via ffmpeg; run content analysis to…

Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…
