This, from Stratechery, is fun to extrapolate. Your phone has 10-20 Wh of battery per day. In the coming years, asymptotically, ~all of that may go to AI. Everything else your phone does will be forced to fit into fewer and fewer watts.

Biggest surprise of having a baby: I now laugh at Instagram Reels.

MAML is still one of my favorite Deep Learning ideas. Reframing the problem of "let's train a model" to "let's train a model that is a few gradient steps away from lots of different useful models". (Maybe foundation models + LoRA is our closest analog.).
Presented a fun topic this morning. If you think of the brain as essentially a few-shot learning machine, you can imagine it solving other problems (e.g. continual learning) by framing them as few-shot learning problems. For a succinct colorful summary, maybe watch 37:30 - 38:50.

Claude Code's comments seem like satire. Real example from Opus 4.1:.```. // Apply gray color (0.5, 0.5, 0.5) to the text. float3 grayColor = float3(0.5, 0.5, 0.5);.```. It's kinda adorable, clearly the transformer used the code comment to "think" about the next line.

New blog post: "Smooth Pursuit, and how Screens Don't Mimic Reality". Your brain makes clever use of smooth eye movements. This works in the real world, but it fails on screens.

The blue checkmark “reply boost” is an example of how DEI programs can go wrong. It creates the illusion that people with blue checkmarks are under-qualified.

From the blog post: "more than 99% of them had no activity in the last month". This is a classic product data decision-making fallacy. The right question is "how much total value do all of the links provide", not "what percent are used".
Oh come on, how hard could it be to keep these links working forever? It could be like a 5-line Worker backed by KV and you'd never have to touch it once deployed.

My new favorite hidden iOS feature: Background Sounds. Add it to your Control Center. Then listen to Daft Punk + rain

Here's what I've inferred:.Apple actually *does* expect people to use the second platform. But they also want to be able to change that platform between releases. So their solution is: make developers feel they are doing something "naughty". It's an elegant solution.

Many (ex-)Microsoft employees would gasp at the thought of a first-party web browser calling a private API. WebKit is open-source; you can go to GitHub and see that they are plainly doing this (e.g. just search for the two terms above.).

macOS is a funny platform. It is essentially two platforms:.1. The public API.2. The API for web browsers and "pro" tools. Much of the second platform is private (e.g. CALayerHost) or "deprecated" (e.g. sandbox_init).

Tip: If the YouTube app makes your iPhone super hot, try uninstalling and reinstalling it. (I've been bitter about this for many months. Finally learned about this "fix" today from .

Has anyone else noticed that the YouTube iOS app just burns an incredible amount of battery, starting sometime lately? Any time I am playing a video my phone gets hot (very new iPhone 16) and battery drops rapidly.
