Swift EvolutionのProposalの要約を日本語で読めるサイト"Swift Digest"を作りました。将来的にはBlogの要約なども追加予定です。要約はOpus 4.7、サイトの構築は主にCodexを使いました。自力だと1年かかっても完成しなかったでしょうが、ほぼ1日で作れました。 swiftdigest.koherent.org

冗談抜きでほんまに読み書きしなくなってるんやで diffの雰囲気ぐらいはうっすら眺めてますが ちなみに人間が送ってきたPRは読みます どうせAI使って書かれたコードでもです あくまで「自分が操縦したAIのコードは読まない」です プロセス全体をグリップしてるから confidenceの問題なんす…

Gemini 2.5 ProのDeep Think、2.5 Flashの更新、Agent Mode、検索のAI Mode、Jules、Veo 3、Imagen 4、Flow、Gemini Diffusion、Gemma 3n、Google Meetの同時通訳、バーチャル試着、XRデバイス。どれか一つでも界隈が盛り上がるレベルのプロダクトを、これだけ一度に出されると圧倒される…

この前、娘に英語の疑問文について説明したので、見返してもらうためにショート動画にしてみた！初めてショート動画を作って思ったけど、この尺だと余計な説明が削ぎ落とされて、本当に必要なことだけ残るのでいい感じ。プログラミング解説のショート動画を作ってみるのもいいかも？

Ex Machina is no longer sci-fi. China has finally built it. The company is AheadForm, founded in Shanghai. The product is the world's most hyper-realistic robotic face. Silicone skin you can't tell from human, 25 micro motors hidden underneath pulling the face into real expressions. And RGB cameras embedded inside the pupils so when it looks at you, it actually sees you from where its eyes are. They raised $28.5M to "give AI a head," which is also where the name comes from. AheadForm = a head form. This is the opposite of where everyone else in robotics is focused. Unitree, Figure, Tesla, Boston Dynamics: all about the body. AheadForm chose the face because they think trust is the harder problem to solve, and trust gets decided at the face. The reason nobody else has tried this is the "uncanny valley." It's the creepy zone where a robot looks almost human but not quite, and looking at it just feels wrong even when you can't say why. Most roboticists believed no amount of engineering could make a face realistic enough to escape it. So they gave up and kept robots cartoonish on purpose: big anime eyes, exaggerated features, clearly synthetic. But AheadForm decided to treat it as an engineering bug instead. Add enough motors, tune the silicone, fix the timing, the valley closes. And they're pulling it off. A few crazy details about how this actually works: 1. The robot learns its own face in a mirror. You put it in front of a camera, let it fire every motor randomly, and it watches what its face does and builds an internal map of "if I send command X to motor Y, my eyebrow does this." Same exact process a human baby uses staring into a mirror. The robot teaches itself who it is by experimenting. 2. It predicts your smile 839 milliseconds before you smile. By watching the micro-tells in your face that precede a smile, the robot starts smiling 0.8 seconds ahead, so its smile lands at the same moment yours does. Most robot mimicry happens half a second late, which is exactly why it always feels artificial. 3. The pupils are the cameras. When the robot makes eye contact, the gaze and the sensor are the same physical thing. Most humanoid robots stick the camera on the forehead or chest, so they aren't actually looking at you when their eyes are pointed at you. 4. The founder, Yuhang Hu, did his PhD at Columbia under Hod Lipson. Lipson is the guy who in 2006 built a four-legged robot that figured out it had four legs by experimenting with its own movement, nobody told it the body shape, it discovered it. He has spent 25 years trying to build machines that know what they are. AheadForm is that 25-year research arc productized. 5. NetEase Games already paid them to physically embody a fantasy video game character. That opens up a brand-new category: robotics as the physical embodiment of fictional IP. Every character-rich studio, Disney, Riot, Hoyoverse, Pokemon, Netflix, now has a question to answer about when their characters get bodies. AheadForm believes whoever ships the first robot you'd actually want around your family wins. That's the bet behind the most realistic robot face on earth.
