A frustration I've had since switching to VS Code last year from terminal vim is that the built-in source control extension isn't very keyboard-friendly. As a result, I've been tabbing back and forth between VS Code and Fork and kicking myself every single time, especially when I'm just editing a single file and I really don't need to review my changes before I push.

Well, I finally took the five minutes to write a VS Code macro to do this for me. First, run Open Keyboard Shortcuts (JSON) and add this to the array of keyboard shortcuts:

{
    "command": "runCommands",
    "key": "cmd+alt+ctrl+p",
    "args": {
      "commands": [
        "workbench.action.files.save",
        "git.sync",
        "git.stageAll",
        "git.commitAll",
        "git.push"
      ]
    }
  }

Now when I smoosh command, option, and control, then hit P, it'll pull from the tracked remote branch, stage & commit everything, open a window for me to enter a quick message (usually "lol"), and then when I hit command-w, the result will be pushed. Saves me about 10 seconds per commit.

Vision Pro with the Good Strap

UPDATE: It works! Photo here

As I mentioned in my review podcast, the two straps that ship with the $3500 Apple Vision Pro are god-awful and mediocre, respectively.

If you just spent that much money on this thing, do yourself a favor and buy two more things:

1. A BOBOVR M2 Plus strap

2. This 3D-printed conversion kit for connecting it to Vision Pro (you can also print it yourself)

And boom: for under $50 you'll have a comfortable way to actually use the Vision Pro. Shame on Apple for dropping the ball so badly in the name of aesthetics (what happened to, "design is how it works"?), but hat tip to Mark Miranda for pointing me to this Etsy listing.

Still got it

I have somehow been using Ruby on Rails since 2005 and have never worked on an app that needed to think seriously about web request caching, probably because of my proclivity to reach for static site generators and simple asset hosting whenever anything I make will be public-facing. But the current app I'm working on is actually mostly accessible without requiring users be logged in, which means it will both (1) run the risk of having bursts of hard-to-anticipate traffic to certain pages and (2) render pretty much the exact same markup for everyone.

I'll start with the results. Here's a mostly-empty, public-facing page my basic Heroku dyno without caching:

Completed 200 OK in 281ms (Views: 201.9ms | ActiveRecord: 47.5ms | Allocations: 37082)

And now with a few lines of caching setup:

Completed 200 OK in 9ms (Views: 3.5ms | ActiveRecord: 1.6ms | Allocations: 2736)

So over 30 times faster. And that's on a very basic page. Once the site is primed with content it'll probably be even more dramatic.

Here's how to do it.

This'll be an insta-purchase for me before it can get yanked from the App Store:

Juno delivers a fully native visionOS UI that taps into YouTube’s embed API, which is designed to allow videos to be embedded in external webpages. When you want to browse YouTube’s video catalog, Juno pulls up a tweaked version of the YouTube website. Apparently, the app is even clever enough to not show ads for YouTube Premium subscribers, though it remains to be seen how Google feels about a third-party developer being in control of an app for one of its biggest services on a new piece of hardware. Selig notes that he didn’t use any private/internal APIs to develop the app.

I'm not one to kink shame, but it's starting to feel like this guy's fetish is building businesses whose survival depends on the mercy of hostile platform holders.

Apple PR:

More than 600 apps and games designed to take advantage of the unique and powerful capabilities of Apple Vision Pro will be available this Friday, February 2.

For context, iPad launched with just shy of 5000 apps in its App Store, and that number nearly doubled to 10,000 within a couple months.
