Android Studio fully supports Apple silicon (arm64).
There are significant improvements for developers working on Macintosh computers based on Apple silicon devices. As a leading integrated development environment for creating android apps, Android Studio now fully supports Apple’s M series of chip architectures, delivering a smoother and faster experience. This optimisation dramatically enhances performance, from compiling code to running emulators. Developers leveraging Apple Silicon can now expect reduced build times, better memory management, and more efficient multitasking. These improvements translate into a development process that is not only faster but also more responsive, ensuring that the focus remains on crafting exceptional android apps.
The update also extends to the emulator, which now runs natively on Apple Silicon. This ensures that developers can test their apps with minimal latency and greater accuracy, mimicking real-world scenarios seamlessly. The native support further reduces reliance on translation layers, such as Rosetta 2, providing an overall performance boost for the entire development workflow.
By fully embracing Apple Silicon, Android Studio empowers developers with cutting-edge tools. This ensures that whether you're building robust enterprise solutions or innovative consumer applications, your development environment operates at its very best.
TL:DR—Download and drag to /Applications to install, then complete the first-run setup, add an arm64-v8a system image and run the emulator. Marvel at how fast it is, or how slow it was before on Intel perhaps!

Flutter 2.0 on Ubuntu 21.04 is here!
"Flutter SDK snap build integration makes it easy to publish your multi-platform Flutter app for one-click install by millions of Linux desktop users." — So says the press release. Lets find out.
We've been working with Flutter for over two years now, creating Android and iOS apps from the same source code. With nearly 30 Flutter based apps in the App Store and Google Play. Flutter 2.0 adds Linux support and Ubuntu made a point of making it part of their Ubuntu 21.04 release. This is an indication of direction of travel. Flutter is capable of building robust mobile apps. The Linux support is new, but it is built on the same foundation. The promise of cross plaform app development is often mired in technical difficulties but this time there is something different in the level of industry collaboration and support for Flutter with some notable exceptions.
Hello, world on Ubuntu 21.04
Flutter 2.0 can now create Ubuntu 21.04 desktop apps, This is the hello world example app.
TL:DR— Getting this running too around a dozen commands, and a bit of default question answering in both Flutter and Android Studio, which you have to launch once its installed. It took about 15 minutes to set up.
$ sudo snap install flutter --classic
$ flutter sdk-path
$ export PATH="$PATH:/home/yourusernamehere/snap/flutter/common/flutter/bin"
$ flutter config --no-analytics
$ sudo snap install android-studio --classic
$ flutter config --android-studio-dir /snap/android-studio/current/android-studio
$ flutter doctor --android-licenses
$ flutter config --enable-linux-desktop
$ flutter doctor
$ cd ~/Projects
$ flutter create hello_world
$ cd hello_world/
$ flutter run -d linux

Firefox screenshots
I think I was quite cross when I wrote this. It doesn't seem so important now.
"The ‘Take a Screenshot’ feature was removed from the Page Actions menu in the url bar. To take a screenshot, right-click to open the context menu. You can also add a screenshots shortcut directly to your toolbar via the Customize menu. Open the Firefox menu and select Customize…"
Well thats half an hour of my morning I won't get back. Progress I suppose. Something I use every day requires a toolbar customisation like its 1992, or for me to use the context menu if it hasn't been disabled.
TL:DR— You can right click to open a context menu to take a screenshot and you can also add a screenshots shortcut directly to your toolbar via the Customize menu.

Theres generally one single corporate strategy in an oranisation.
TL:DR – Robust strategies are about survival in the long term ensuring all threats are managed. Corporate strategies more generally are about optimising current performance. The main targets of strategies are customers and staff. These are fragments of notes from a course I took on Strategy with the OU.
