In some more fun #puregotk #GNOME news - I managed to get Meson to work on macOS. You can even write a GObject library in Go now, compile it to a dylib and typelib, and then another puregotk-based app (or GJS, Python etc.) can load the custom widget and display it with no issues!
Even cooler - you can cross-compile this for macOS from Linux, no CGo/macOS C compiler required :)

Kind of neat how well #GNOME apps fit in on macOS :) Since @npub17ds…pmve added support for macOS to #puregotk in https://codeberg.org/puregotk/puregotk/pulls/43 this week I thought I’d give it a shot on my new MacBook Neo - and it works really well. Cross-compilation from Linux to macOS was super easy thanks to purego, no cross-compiler needed, just `GOOS=darwin GOARCH=arm64`. Plus, discovered that macOS’s arm64 library paths are different!

Anyways, heading to Shenzen again tomorrow and going to see how far I can get with just a Linux phone. If I can pay for and control the massage chair in the local mall with it (WeChat mini app) I'm going to actually go crazy because in Canada the same phone can't even buy me a sandwich

2026-03-11 15:49:25 CET

The fact that I can use a Linux phone in China and be a fully participating member of society, including mobile payments and everything, but I can't do that in any EU country, the US or Canada due to the payment methods there requiring SafetyNet and China not requiring that, has really broken my brain a little bit

Kind of? I don't know. There is a way to make Linux systems reasonably secure. There is no currently known way to make something like OpenClaw secure due to fundamental limitations around prompt injection.

2026-02-23 10:31:42 CET

I think the reason why some people really like things like OpenClaw is just because of the fact that they seem ... liberating in a way. The idea of you being able to have your own interface, commands, and automations, all customised, open, running on your own systems ... it's like a dream. It's also simply _impossible_ using the current incentives in society (which will probably start abusing DRM APIs to prevent you from automating screen taps and stuff), and just so absurdly dangerous ...

Will do! I've done tons of WebDAV stuff in the past, and the core functionality of the Nextcloud client is literally just syncing files and folders + polling notifications for logins etc., and that can probably be optional too. Virtual files would be a bit complex to support, but I feel like that's what the FUSE which GNOME already ships is for anyways. The WebDAV login credentials I can probably even fetch from the secrets store so that you don't have to sign in again.

It's always been a balance of embracing new technologies (and reaping the benefits it might have - while also dealing with the constant distraction of shiny new things) vs. staying narrow and fighting scope creep, but potentially becoming obsolete.

Can US media stop pretending that the tarrifs are "reciprocal"? Or that the numbers Trump shows for what e.g. the EU charges on US imports is anywhere close to what it actually charges? There just simply is no 39% tarrif that the EU charges on US goods, it's completely made up

I guess it depends what that "additional software" here is. Containers/OCI images? Sure. Flatpaks? Sure. EBPF code? Sure. Random privileged `run0` replacement vendored as a statically linked binary? Not really. Out-of-tree kernel driver like the type you would usually install with akmods? Also not really.

Oh no I think that makes a lot of sense for postmarketOS specifically, and as a dev I see myself using something like this. But for end users I really want it to be impossible to change the rootfs without sandboxes.

I'm not completely sure if I agree with that. Stuff like the meta build system for GNOME OS is now able to bootstrap an entire, basically end-user ready OS without any packages (unless I'm missing something).

As a dev, personally I really value having a direct relationship with my users with no one between them and I. The DMA gives every EU citizen the right to this now too, so the regulatory environment is pretty clear on it as well. Flatpak finally makes this possible on Linux, and I think it's the primary reason why it's the future compared to the old sea of packages. The time of middle men in software is over

> You're giving this take at the same time as we're seeing more and more supply chain attacks exploiting exactly this model (where the language comes with a package manager).
Honestly I think that's just a matter of most software these days being written this way/with heavy use of per-language packages. Ofc if most software is written this way most of the vulnerabilites of the supply chain will be made through that infrastructure

Oh for Python I 100% agree, that package ecosystem is a mess of unbelievable proportions. I don't think I've once been able to pull a Python project from source and have it just work. That's very specific to Python not having a `package.json`, lockfile & Bundler concept though IMHO. Go, Rust and JS are very different from this.

2024-07-03 04:50:04 CEST

I think the problem mostly is that "sea of packages" OSes don't support very basic requirements of modern apps. Multiplex depends on a specific version of the `pion` WebRTC library, but weron depends on a different specific version of that library too. With a sea of packages and no Flatpak - no way to model that environment. APT, DNF etc. don't really allow different (minor) versions of the same package locally for a lot of (good) reasons :)

2024-07-03 04:45:47 CEST

- reply

Oh and neither should they be! It depends on whatever language those are written in. Need a codec written in Go? Include it in your Flatpak by building it with the Flatpak Go SDK. Need a codec written in Rust? Include it in your Flatpak by building it with the Flatpak Rust SDK. No such thing as a "host codec" when all apps are Flatpaks after all :)
As for kernel modules - those are special :) I wonder if there will be a systemd-sysext equivalent for them some day.

2024-07-03 04:37:14 CEST

- reply

Well the compromise is to use the language's package manager (npm, pip, cargo, go get etc.), in a container if necessary. C is probably the only exception, although in the case of Flatpak that's also a dependency that would be defined that way after all.
`apt install node-lodash` is the path to insanity IMHO.
