One thing that I wish macOS did better was multi-monitor support. I have two fairly recent Dell monitors on my desk daisy chained via thunderbolt (to mac) and DP (to second monitor). And when I plug in the mac its hit and miss as to whether its going to work or not.

Experimenting with the idea of #hex1b having its own web-based terminal renderer that uses WebGPU. All of the terminal state stays server side with the Hex1bTerminal instance, but state updates are transmitted over the wire via a websocket to some JS code that renders onto canvas.

Mitch Denny

The #hex1b terminal stack includes its own terminal emulator which maintains what it things the terminal state is even if you are connected to a real emulator - so conceptually this is just projecting that terminal state onto a web canvas. At this point there are lots of question marks around perf.

Just tested out my Sixel Cloud demo in the web terminal and it seems to work OK. Fair amount of data flowing across the pipe though but TBH xterm.js doesn't handle it at all (although I'm not saying this terminal is better than xterm.js at all).

Sixels is a pretty old school terminal graphics capability which has gotten a bit of more attention recently. Increasingly modern terminal are adopting Kitty Graphics Protocol - but there are some terminals out there that support Sixels. Here is WezTerm running a simulation.

KGP animation support in a Hex1b TUI application. The terminal in this case is Kitty (because Ghostty doesnt' support animation in the current released build). But what I am showing off here is Hex1b handling composing and animating multiple images including occlusion in the TUI framework.

Fresh terminal emulator challenge. This video shows a Hex1b app with multiple independent terminal widgets running inside the TUI framework - but the interesting thing is that KGP graphics are flowing through from the nested terminals to the outer terminal. Needed this for a feature in Aspire 13.6

12 months ago I would never have believed that I could give a coding agent a prompt like this and expect that it would do the right thing (using #GitHub app BTW):

Mitch Denny
@mitchdenny.dev

In order to figure this out the agent is going to have to make sure that its running a vendored build of xterm.js in a sample app in the repo which in turn runs a nested sample app. It then needs to analyze some recent PRs to spot the regression and create a fix.

Mitch Denny

This is all from within a nested session that it created to automatically manage its context window as part of a massive push to improve KGP conformance in #hex1b.

Hello @aspire.dev / #aspire friends. Does anyone deploy their apps directly on VMSS clusters these days? I have a proof of concept of `aspire deploy` being able to hoist an app and run it directly on a VMSS cluster but I'm not really sure how common this scenario is these days.

A few folks on the @aspire.dev team have been putting some polish on the Aspire dashboard this iteration and I just played with it in a build from main and its looking really nice. Not one thing in particular but lots of little refinements.

I watched the final episode of season 6 of "For All Mankind" last night. Fantastic stuff. I'm looking forward to season 7. My favorite part of every season is the first episode where they fast forward time.

Been binge watching For All Mankind and every single time Columbia takes off I hold my breath hoping that nothing happens to it in this alternate universe.

There is a flavor of AI-generated YouTube video that keeps showing up on my feed which proclaims how awesome Gen-X is. They are total bullshit. There was one that had completely fabricated research and very flawed reasoning on IQ by generation (spanning about 100 years).

Mitch Denny
@mitchdenny.dev

I am sure every generation has content like this targetted at them, probably optimized by channel. But you have to ask yourself - who is burning the tokens to generate this content - and why? If you can't answer they are probably trying to sell you something or influence you in some way.

A fearless, independent ABC that is free for all Australians is worth fighting for. Sign the petition to reject calls to defund the ABC force it onto a subscription model that would price out the Australians who need it most. abcfriends.au/actions/keep...

Adding some real 3D support to #hex1b tonight. But this also shows off an upcoming feature in Aspire 13.5 ... web-based Terminal support. The demo here is a TUI app built using Hex1b running under #aspire accessible via the dashboard via our new terminal emulation feature.

Mitch Denny
@mitchdenny.dev

An even more extreme demo. This one is a Hex1bTerminal being projected as the input for a texture being applied to a plane being rendered in a Hex1b scene widget. The border around the outside is a boder widget that has been rasterized to half blocks as it was projected into the plane.

Have been working on a fairly large feature in #aspire for an extended period. Lots of new files, lots of iterations. Managed to really hit the limits of feature iteration with Copilot and an Opus model. About 17,000 lines added over 96 commits.

Mitch Denny
@mitchdenny.dev

This PR was also backed by a similarly sized PR in our sibling DCP repository because the feature required plumbing right down into the process launcher (thanks to Karol for landing that!).

Doing some test deployments via our AKS integration in #aspire 13.4 and just saw this content served up from our starter template app. Whatever place this weather is for I don't want to live there! 51c is rated as "Cool" :P
