All New Raspberry Pi 400, WinApps, Uno Platform, and more. | biweekly #3

This is the 3rd biweekly roundup of noteworthy news articles, blog posts, launches, and other cool Linux-related content that I’ve come across over the past two weeks.


Raspberry Pi 400: personal computer, built into a compact keyboard.

Raspberry Pi 400

Raspberry Pi 400 incorporates a purpose-built board based on Raspberry Pi 4. Featuring the same powerful processor, Raspberry Pi 400 has specially designed thermals to keep your computer cool and silent while you’re hard at work. The GPIO pins remain accessible, so if you want to explore beyond the desktop, you can connect components and prototype your projects.

The Raspberry Pi personal computer kit comes with a mouse, power supply, micro HDMI to HDMI cable, and SD card preloaded with Raspberry Pi OS. There’s also the official Raspberry Pi Beginner’s Guide, and the Raspberry Pi 400 is also available as a standalone unit.


WinApps: Run Windows apps in Linux


Run Windows apps such as Microsoft Office/Adobe in Linux (Ubuntu/Fedora) and GNOME/KDE with WinApps as if they were a part of the native OS, including Nautilus integration.

WinApps works by:

  • Running a Windows RDP server in a background VM container
  • Checking the RDP server for installed applications such as Microsoft Office
  • If those programs are installed, it creates shortcuts leveraging FreeRDP for both the CLI and the GNOME tray
  • Files in your home directory are accessible via the \\tsclient\home mount inside the VM
  • You can right-click on any files in your home directory to open with an application, too


Uno – Single-Codebase for Linux, Android, Windows, iOS, and macOS.

Uno Platform

With the Uno Platform, you can empower your existing .NET teams to build pixel-perfect, single-codebase, multi-platform web, mobile, and desktop apps.

Uno Platform acts as a bridge for WinUI and UWP apps to run natively on iOS, macOS, Android, Linux, and WebAssembly. You can run your C# and XAML source code unmodified and compile it on a different platform yet have it behave the same at runtime. In turn, you, as a developer, automatically benefit from decades of Windows ecosystem investment in responsive design, security, accessibility, and more.


Sandbox Linux Applications

Firejail is a SUID program that reduces the risk of security breaches by restricting the running environment of untrusted applications using Linux namespaces and seccomp-bpf.

Firejail can sandbox any type of process: servers, graphical applications, and even user login sessions. The software includes security profiles for a large number of Linux programs: Mozilla Firefox, Chromium, VLC, Transmission, etc. To start the sandbox, prefix your command with “firejail”:
