• STM32WL based LoRa-5E development kits go for $19.90 and up

  The LoRa-E5 STM32WL module we covered last month can now be found in two LoRaWAN development kits from Seeed Studio with the ultra-compact LoRa-E5 mini board, and the Arduino UNO shaped LoRa-E5 board with more I/Os. Both boards support the LoRaWAN protocol with global frequencies and can achieve a transmission range of up to 10 km with ultra-low power consumption.

• NXP unveils ultra-secure i.MX9 and low-power i.MX8ULP SoCs

  NXP previewed an NPU-enabled “i.MX9” platform and unveiled low-power, Cortex-A35 based i.MX8ULP and Azure Sphere enabled i.MX8ULP-CS SoCs — all with and “Energy Flex” power management and “EdgeLock” security. NXP offered a glimpse into some foundational technologies of an upcoming i.MX9 family of processors, including “EdgeLock” on-die security, RISC-V-based “Energy Flex” power management, and the Arm Ethos U-65 microNPU for AI acceleration. The Netherlands-based chipmaker did not, however, detail the CPU architectures, core counts, performance, GPUs, and other details.

ytfzf - Search (With Thumbnails) And Play YouTube Videos From A Terminal

ytfzf - search and play youtube with thumbnails from the command line ytfzf is a script to search, download and play YouTube videos by making use of mpv and youtube-dl under the hood. It works on Linux and macOS. The command line script had its first stable (1.0.0) release today. The tool initially started as a single line script, but has since evolved, recently gaining the ability to show YouTube thumbnails in the terminal, along with other enhancements. For each YouTube search query, a list of results in shown in the right-hand side pane. On the left-hand side you can see the selected video title, the channel that posted the video, the number of views, video duration, upload date, and the video thumbnail (which is optional). Use the Up and Down arrow keys to navigate through the search results, and press the Enter key to play the video (or download it, it ytfzf was started with the -d command line parameter). The videos are played using mpv by default, but you can change this with another video player, as long as it has the ability to launch YouTube links.

• Build a printer UI for Raspberry Pi with XML and Java | Opensource.com

  Creating a GUI from scratch is a very time consuming process, dealing with all the positions and alignments in hard code can be really tough for some programmers. In this article, I demonstrate how to speed up this process using XML. This project uses TotalCross as the target framework. TotalCross is an open source, cross-platform software development kit (SDK) developed to create GUIs for embedded devices faster. TotalCross provides Java's development benefits without needing to run Java on a device because it uses its own bytecode and virtual machine (TC bytecode and TCVM) for performance enhancement. I also use Knowcode-XML, an open source XML parser for the TotalCross framework, which converts XML files into TotalCross components.

• How to Use Tails Linux OS in VirtualBox Virtual Machine - Linux Shout

  Well, Debian-based Tails is not the Linux system that we can install on our PC like Windows or other Linux distros. Instead, it is a hardened Linux system meant to run in a Live environment via DVD or USB stick. So it offers extensive security. Here we learn the steps to set up, run and use Tails in VirtualBox Virtual Machine to learn and get familiar with it. The Tails Linux distribution is designed as a live system particular for data protection and anonymity on the Internet. We can easily write in on a USB drive using software such as Rufus or Etcher; or else burn it on a DVD. This makes it a portable Linux OS that a user can use on any system without leaving a trace behind or storing any data on the computer’s hard drive.

• Installing latest syslog-ng on openSUSE, RHEL and other RPM distributions

  The syslog-ng application is included in all major Linux distributions, and you can usually install syslog-ng from the official repositories. If the core functionality of syslog-ng meets your needs, use the package in your distribution repository (yum install syslog-ng), and you can stop reading here. However, if you want to use the features of newer syslog-ng versions (for example, sending log messages to Elasticsearch or Apache Kafka), you have to either compile syslog-ng from source, or install it from unofficial repositories. This post explains you how to do that.
