iPhone 8 with Iris Scanner? →

Seeing sketchy rumors that iPhone 8 may have an iris scanner like the Samsung Galaxy Note 7. I'm still having a hard time seeing how that it better than a fingerprint scanner under the touch screen.

But to Samsung's credit, the most interesting part of having both a fingerprint scanner and an iris scanner is the software aspect — two tiers of security and authentication. Works great for parents who need to protect access to certain data while giving their kids freedom to play games.

A more Apple solution would be to simply let different fingerprints unlock different things instead.

Proposal: Channels for Micro.Blog

Twitter makes the assumption that when you follow a person, you want to follow all of their posts. But I don't think that's a good assumption — I follow a person because I want to follow a particular interest they post about.

How many of you guys are techies who just love to see your favorite tech personalities blow up your feeds with TV shows or football or politics that you don't care about?

I've always loved the way Pinterest was set up — the main focus is you follow a person's interests in the form of Pinterest Boards, not the person.

If micro.blog is truly meant for microblogging as opposed to being a traditional social network, then we should make it easy to follow an person's interests (i.e. an account's categories).

One possible solution is presenting interests/categories like this: @username/channel

So some examples would be:

  • @theverge/apple
  • @gruber/baseball
  • @parislemon/football
  • @amc/TheWalkingDead_EST
  • @amc/TheWalkingDead_PST
  • @espn/nba_highlights
  • @espn/warriors_news
  • @samsung/usa
  • @samsung/korea

Granted, most of those examples are with real-time live-tweeting in mind, but you get the idea.

Of course, the simplest alternative solution is to say, "just create another account", but keeping all categories under the same roof strengthens the main account. Plus, nobody likes to rebuild a following for a new account from scratch.

The idea is not to just "be better than Twitter"; I'm trying to solve the problem that following specific interests should be much more efficient than what is currently out there.

I'm embracing the idea that microblogging does not equal tweeting. And I'd argue that if microblogging is really about sharing content instead of having conversations, we should have more efficient ways of organizing what we share and how we follow it.

Cities in the Smart Car Era →

Johana Bhuyiyan at Recode, imagining how cities will evolve with self-driving cars:

Local governments will have to reimagine how cities are designed. Will roads become shared space for self-driving cars and pedestrians? Will infrastructure like traffic lights and signs need to communicate with vehicles? And since you'll be able to automatically summon your car, from a parking lot miles away, who needs a garage attached to their house? […]

And cities may look drastically different. Sidewalks could go away, as pedestrians and cars share the roads. There will be no street parking, just parking garages outside of city centers. And traffic signs and infrastructure may disappear — replaced with smaller, cheaper equipment that only needs to communicate with cars. Their drivers will be gone.

Virtual Reality is the Opposite of Cinema →

Ken Perlin:

I was on a panel this evening about the future evolution of VR. At one point I made the argument that people who try to “make their film in VR” are getting it very wrong. In fact, I argued, VR is essentially the very opposite of cinema.

The most salient feature of a movie is that everybody in the audience sees exactly the same thing. The goal of a cinematographer, an editor, a lighting designer in movie making is, in fact, to optimize for a single viewpoint. The craft of filmmaking is built around this fundamental imperative.

In contrast, future content in VR will have far more in common with theater: Everybody will see events unfold from their own unique viewpoint. VR has even more in common with immersive theater, in which audience members are free to roam around on their own.
