96.8 percent of new smartphones sold are either iPhone or Android devices

Filed under
Android

The latest quarterly smartphone sales data from Gartner is out today, and it tells a very familiar story. BlackBerry keeps shrinking, Microsoft is stagnating, and Google and Apple are tightening their already dominant grip over the entire market.

  • 22.04 LTS now available for $1299 and up

    The Dell XPS 13 Plus Developer Edition is an unusual looking thin and light laptop that ships with Ubuntu Linux pre-installed rather than Windows. When the notebook first went on sale in April it shipped with Ubuntu 20.04 LTS, but now Dell is shipping the laptop with Ubuntu 22.04 LTS instead.

  • The software defined programmable logic controller: An introduction to Red Hat’s predictable latency / realtime capabilities

    The software-defined industrial control system is a huge opportunity for open source technologies. Moving away from bespoke specialized hardware (like PLC devices) to standard hardware with software only is a trend that crosses industries, extending now into the industrial and manufacturing world. This type of shift for industrial organizations is similar to telcos moving to network function virtualisation (NFV) and open radio access networks (ORAN).

Kernel: New Mesa RC, KVM Update, and Security Posturing From NSA-Connected Companies

  • [ANNOUNCE] mesa 22.2.0-rc2
    Hi list,
    
    It's that time again, mesa 22.2-rc2 is now avilaable. We've had lots of
    changes here, including a bug in my release script setting the version
    to 22.2.0 (oops)! Per normal, Mike is leading the pack with zink
    changes, but we've got fixes all over the tree here.
    
    See you again next week, same bat time, same bat channel,

  • Direct host system calls from KVM [LWN.net]

    As a general rule, virtualization mechanisms are designed to provide strong isolation between a host and the guest systems that it runs. The guests are not trusted, and their ability to access or influence anything outside of their virtual machines must be tightly controlled. So a patch series allowing guests to execute arbitrary system calls in the host context might be expected to be the cause of significantly elevated eyebrows across the net. Andrei Vagin has posted such a series with the expected results. The use case for Vagin's work is gVisor, a container-management platform with a focus on security. Like a full virtualization system, gVisor runs containers within a virtual machine (using KVM), but the purpose is not to fully isolate those containers from the system. Instead, KVM is used to provide address-space isolation for processes within containers, but the resulting virtual machines do not run a normal operating-system kernel. Instead, they run a special gVisor kernel that handles system calls made by the contained processes, making security decisions as it goes. That kernel works in an interesting way; it maps itself into each virtual machine's address space to match its layout on the host, then switches between the two as needed. The function to go to the virtual-machine side is called, perhaps inevitably, bluepill(). The execution environment is essentially the same on either side, with the same memory layout, but the guest side is constrained by the boundaries placed on the virtual machine.

  • ESP32 board with rotary encoder gets 2-key keypad shield - CNX Software

    LILYGO TTGO T-Encoder, a round-shaped ESP32 board with a built-in rotary encoder, has gotten a shield with a 2-key keypad based on WCH CH552 8-bit microcontroller. Launched several months ago, the TTGO T-Encoder is a USB-powered rotary encoder with ESP32 microcontroller offering WiFi and Bluetooth connectivity, and now, you can build a keypad with rotary encoder thanks to T-Encoder shield that features two mechanical switches and keycaps with RGB LED backlight.

  • AquaPing is an open-source, battery powered acoustic water leak detector module (Crowdfunding) - CNX Software

    The AquaPing is an open-source hardware, ultra-low power acoustic water leak detector sensor based on Texas Instruments MSP430 microcontroller and a microphone that can detect leaks without having to do any plumbing, instead capturing audio for water leak detection, and it even works for leaks behind walls. All signal processing and analysis occur on the MSP430 MCU, so no audio is streamed to the cloud and eavesdropping is impossible, plus the sensor only captures high frequencies out of the range of normal conversations, so eavesdropping is not feasible, plus those higher frequencies are also said to provide highest sensitivity and reliability.
