Meet high-performance MapKit JS

MapKit JS provides a JavaScript API to embed interactive Apple Maps directly into your webpages or apps across different platforms and operating systems, including iOS and Android. Learn about the latest features to help improve load performance and make your web and native apps more responsive and faster — all while giving you more control.

If you are an Apple Developer Program subscriber and needs an interactive map on your website, you should try MapKit JS.

I made an effort to improve its start-up performance last year. Everything accumulated to this Tech Talk recorded and published on Apple Developer website.

It is also nice to be informed that one of the slides made it to the front page today:

Webspaces and the retro Web

I am exceptionally intrigued by how Webspaces, made by Greg Fodor as a take on the 3D Web, is similar to the retro, “Web 1.0”-era Web. I commend Greg for his deep insights and technical knowledge as shown in his detailed explainer on Webspaces.

Webspaces: Rebooting the 3D Web

tl;dr: Webspaces is a new way to create self-hosted 3D worlds on the web using just HTML. Visit, join the Discord, play around in an example on glitch, or download a blank webspace to get started!

In his post, you would appreciate these, especially as an old guard who’d experienced “Web 1.0”:

  • The need to lower the barrier of self-hosting to a point of just a pile of static files to avoid gatekeepers and walled gardens (remember Geocities?)
  • Self-editing, or “web writeback” as what Greg said, to fulfill the promise of WorldWideWeb (the first browser) to keep the web a two-way medium. I still vividly remember the excitement when I saw TiddlyWiki achieving that back in the day, though with a different method.
  • The ingenious way of leveraging one, almost free CloudFlare Worker to achieve WebRTC signaling (almost feel like old guest books that you’d embed.)

Having only played Counter-Strike in my past life and not anything remotely similar metaverse-y like Minecraft, I am not entirely convinced that is how people will be interacting with “the” next, non-niche social network.

The keyboard, mouse, and the 2D screen (at best with audio/video), just don’t feel like the right hardware to experience a 3D space for the messes. The right hardware is perhaps have not been invented yet; the browser for 3D Web is yet to be seem.

That said, you should go visit that link and read his full post. I am sure it is a milestone of the future, popularized 3D Web, when historians tried to connect the dots.

PS. I don’t know Greg personally, even though we worked in the same company. Happy to be introduced.

Cookies: the most consequential Web technology

I was meant to expand my thoughts on cookies previously blabbed on Twitter, but NPR’s Planet Money did a much better job than I did there: How the cookie became a monster.

The episode faithfully covered how cookies was invented at Netscape out of the necessity to enable commerce on the Web, and how DoubleClick repurposed it to enable targeted advertising. The episode also covered GDPR and mentioned browser vendors’ eventual plan to phase out cookies.

What the episode didn’t mention was how targeted advertising was abused to enable foreign interferences on democratic elections.

As an informational piece, they didn’t cover opinions on politics between and within browser vendors on deprecating cookies. That’s maybe something I am not in the position to comment either.

Anyway, like every technology, there are abuses and unintended consequences, even the democracy-destroy ones.
