The tips are fun and the hope of discov- ering hidden gems makes it a worthwhile task. John Southern Former editor of Linux Magazine I enjoyed Ubuntu Kung Fu and learned some new things. I would rec- ommend this book—nice tips and a lot of fun to be had. Carthik Sharma Creator of the Ubuntu Blog (http://ubuntu.wordpress.com) Wow! There are some great tips here! I have used Ubuntu since April 2005, starting with version 5.04. I found much in this book to inspire me and to teach me, and it answered lingering questions I didn’t know I had. The book is a good resource that I will gladly recommend to both newcomers and veteran users. Matthew Helmke Administrator, Ubuntu Forums Ubuntu Kung Fu is a fantastic compendium of useful, uncommon Ubuntu knowledge.

  • Performance Assessment of Linux Kernels with PREEMPT RT on ARM-Based Embedded Devices
    electronics Article Performance Assessment of Linux Kernels with PREEMPT_RT on ARM-Based Embedded Devices George K. Adam 1,* , Nikos Petrellis 2 and Lambros T. Doulos 3 1 CSLab Computer Systems Laboratory, Department of Digital Systems, University of Thessaly, 41500 Larisa, Greece 2 Department of Electrical and Computer Engineering, University of Peloponnese, 26334 Patra, Greece; [email protected] 3 School of Applied Arts, Hellenic Open University, 26335 Patra, Greece; [email protected] * Correspondence: [email protected]; Tel.: +30-241-0684-596 Abstract: This work investigates the real-time performance of Linux kernels and distributions with a PREEMPT_RT real-time patch on ARM-based embedded devices. Experimental measurements, which are mainly based on heuristic methods, provide novel insights into Linux real-time perfor- mance on ARM-based embedded devices (e.g., BeagleBoard and RaspberryPi). Evaluations of the Linux real-time performance are based on specific real-time software measurement modules, devel- oped for this purpose, and the use of a standard benchmark tool, cyclictest. Software modules were designed upon the introduction of a new response task model, an innovative aspect of this work. Measurements include the latency of response tasks at user and kernel space, the response on the exe- cution of periodic tasks, the maximum sustained frequency and general latency performance metrics. The results show that in such systems the PREEMPT_RT patch provides more improved real-time performance than the default Linux kernels. The latencies and particularly the worst-case latencies are reduced with real-time support, thus making such devices running Linux with PREEMPT_RT Citation: Adam, G.K.; Petrellis, N.; more appropriate for use in time-sensitive embedded control systems and applications.

It?s an unofficial remix of Ubuntu that will turn your Raspberry Pi into a retro gaming machine. After building the Rolling Rhino, a command-line tool that lets you convert your regular Ubuntu installation into a rolling release, Canonical?s Ubuntu Desktop lead Martin Wimpress is now building a new Ubuntu-based distro specifically designed for Raspberry Pi computers and retro gaming, called Ubuntu Retro Remix. Why retro gaming? Because Martin Wimpress is a hardcore retro gamer who built several Raspberry Pi retro games consoles using cases that imitate the classic retro gaming consoles. RaspEX Kodi for Rpi4, Rpi3 and Rpi2 with LXDE Desktop and Kodi 18.7 Media Center ?Leia? with Netflix, YouTube, Plex and Amazon Video addons ? Build 200713 (32-bit) and Build 200726 (64-bit)[5] The system is made especially for the new Raspberry Pi 4 (8GB, 4GB and 2GB). RaspEX Kodi is based on Debian 11 Bullseye respectively Debian 10 Buster, Raspberry Pi OS (previously called Raspbian) and Kodi Media Center.
