I’m sick of AI prose and miss the good days when good repos had concise, well-written README.

Like this, but the problem with such immediate mode GUI apps is that they constantly burn 1-2% of CPU when the app is idle. A waste of compute and power.

I'm waiting for Phase 2[1]: especially "Algebraic data types & pattern matching". Current tagged union[2] use is pretty awkward/verbose and lacks exhaustiveness checking and typed error handling.

Indeed! I wrote my note-taking app with a block editor (like Notion) in Qt with QML for the UI and C++ for the logic and it's been an incredible experience![1]

The QR code that shows on hovering the "Download" button is very cool! Kudos to the person who came up with that.

I know people would dismiss this, but I'm going to try to make the case for Qt - I'm currently converting my note-taking app to mobile and it's going very well.

Fable was the only model that was able to detect a data corruption bug in my Qt C++ note-taking app[1] that all other tested models (gpt-5.5 xhigh, GLM-5.1, Kimi 2.7, DeepSeek V4 Pro) didn't find. I'll test on GLM-5.2 and Mimo v2.5 Pro soon.

These days you write the logic in C++ and UI in QML which is a very pleasent experience.

It's SwiftUI that is at fault here[1][2], not native apps in general. I wrote my native app in Qt C++ and QML and showed that it is *significantly* faster and uses significantly less RAM than similar web apps[3]. So, no, web apps, in general, are slower and uses more resources than well-engineered native apps.

Yep, this is a difficult problem. I wrote extensively how I managed to solve this by creating my block editor from scratch using Qt C++ and QML[1]. I faced similar issues - selection between discrete blocks, showing the underlying Markdown under the cursor, varying delegate sizes, etc.

I'm using what I learned to create a native LLM client with a streaming Markdown parser[2].

That's not the solution - developers or businesses are squeezed into signing up anyway to survive/make a profit. The only viable alternative is to create an alternative - Linux phones.

We'd have to make Linux on mobile a viable option.

Mojo is a language with Pythonic syntax that compiles to fast machine code built by the creator of Swift: https://www.modular.com/open-source/mojo

Sounds good to me! If you ever need some architectural help I'd be happy to.

I have a lot of experience with Qt and QML, I've created a block editor[1] and an LLM chat client[2] and many other projects.

Doesn't OpenCode supports local models?

I wonder if the Snapdragon X Elite already caught up with the Apple's M series in that regard - does anybody know?

I'm glad Chris Lattner moved on and founded Mojo. It's such a cool language with ton of potential.

Can someone list what are some cool/novel BeOS features that other OSes didn’t have at the time and maybe still don’t have?

This is wrong. There's a misconception that you can't statically link your app when using the open-source LGPL version of Qt. From my reading of the LGPL license this doesn't appear to be the case[1]. The LGPL allows you to statically link your app as long as you provide the object files and allow users to relink your app with a different version of Qt.

I've observed many people spreading this misinformation about only being able to dynamically link with the LGPL version of Qt. Please stop this.

I guess they rely on many people not toggling privacy-mode on?
