Android 12 developer preview released – What’s New?

Google releases a new version of Android every year, and the company is now usually releasing a developer preview in February to allow feedback and testing from app developers. So here we are with the Android 12 developer preview having just been released by Google with changes ranging from trust and safety to media transcoding to support for AVIF image format. Android 12 highlights: Performance Improved Binder IPC calls – Google engineers have had a look at latency and workload distribution, and made optimizations that reduce the median experience. This has yielded roughly a 2x performance increase on Binder calls overall, and up to a 47x improvement in refContentProvider(), 15x in releaseWakeLock(), and 7.9x in JobScheduler.schedule(). Foreground service optimizations – To ensure a better experience for users, foreground service starts from the background will be blocked for apps that are targeting the new platform. Android 12 will also delay the […]

Linux 5.11 Release – Main Changes, Arm, MIPS & RISC-V Architectures

Linus Torvalds has released Linux 5.11 just in time for… “Valentine’s Day”: Nothing unexpected or particularly scary happened this week, so here we are – with 5.11 tagged and pushed out. In fact, it’s a smaller-than-average set of commits from rc7 to final, which makes me happy. And I already have several pull requests lined up for tomorrow, so we’re all set for the merge window to start. But in the meantime – and yes, I know it’s Valentine’s Day here in the US – maybe give this release a good testing before you go back and play with development kernels. All right? Because I’m sure your SO will understand. Linus Last time around, Linux 5.10 was an LTS release that added EXT-4 performance enhancements, improved post-Spectre performance, as well as the enablement of BCM2711 (Raspberry Pi 4) display pipeline, among other many changes. Some of the notable changes in […]

Vacos Cam AI Security Camera Review – Part 1: Specifications, Unboxing and Teardown

As we’ve seen in our Reolink RLC-810A review, AI security cameras greatly reduce the number of false alerts generated by motion sensors, and the Reolink 4K security camera we tested was capable of people and vehicle detection. The Reolink model does not support WiFi, so I had to run a long Ethernet cable, plus a power extension to connect a 12V power adapter since I don’t own a PoE injector. But I’ve been given the opportunity to review another AI security camera, namely Vacos Cam, that also supports human detection, but relies on WiFi connectivity and can be powered by a solar panel removing the need for potentially long cable. As a bonus, it comes with eMMC for storage, so there’s no need for a MicroSD card. In the first part of the review, I’ll list the specifications, unbox the power panel and camera, and tear down Vacos Cam to […]

Ubuntu Core 20 released for secure Linux IoT devices and embedded systems

Canonical has just released Ubuntu Core 20, a minimal, containerized version of Ubuntu 20.04 LTS for IoT devices and embedded systems. The company highlights several security improvements and features of the new version of the Linux-based operating system with secure boot, full disk encryption, secure device recovery, and secure containers. Ubuntu Core 20 is said to come with all benefits from Ubuntu 20.04 LTS such as regular, automated updates, the ability to manage custom app stores, and offers a longer 10-year support window. Ubuntu Core is available and certified on popular32-bit and 64-bit x86 and Arm single board computers such as Intel NUC or Raspberry Pi 4. Minimum requirements include a single-core processor @ 500 MHz, 256MB RAM, and 512MB storage. Alternatively, it’s also possible to run it in a virtual machine on your PC. Security is further enhanced with apps running in containers, and since only the necessary software […]

K210 AI Accelerator Raspberry Pi pHAT targets secure AIoT projects (Crowdfunding)

Kendryte K210 is a dual-core RISC-V AI processor that was launched in 2018 and found in several smart audio and computer vision solutions. We previously wrote a Getting Started Guide for Grove AI HAT for Raspberry Pi using Arduino and MicroPython, and XaLogic XAPIZ3500 offered an even more compact K210 solution as a Raspberry pi pHAT with Raspberry Pi Zero form factor. The company is now back with another revision of the board called “XaLogic K210 AI accelerator” designed to work with Raspberry Pi Zero and larger boards with the 40-pin connector. K210 AI Accelerator board specifications: SoC – Kendryte K210 dual-core 64-bit RISC-V processor @ 400 MHz with 8MB on-chip RAM, various low-power AI accelerators delivering up to 0.5 TOPS, Host Interface – 40-pin Raspberry Pi header using: SPI @ 40 MHz via Lattice iCE40 FPGA I2C, UART, JTAG, GPIOs signals Security Infineon Trust-M cloud security chip 128-bit AES […]

Rockchip RV1109 SBC’s provide access control solutions with optional 4G LTE connectivity

We’ve been writing about Rockchip RV1109 and RV1126 AI camera SoC’s in recent days, as well as evaluation boards and modules, plus some complete solutions such as Firefly dual-lens AI camera modules. Shenzhen-based JWIPC, a company specifically in embedded PCs and motherboards, has designed three SBC’s powered by Rockchip RV1109 processor especially designed for access control, leverage the face detection capabilities of the Rockchip processor. The three access control boards are: R19S – Standard 100x72mm Pico-ITX board with industrial grade materials, support for wide temperature, hardware watchdog, and “rich peripheral interface”. R19F- Same as R19S, but with a mini PCIe socket for a 4G LTE module, plus a SIM card slot R19N – Similar to R19S with a narrower 100x60mm design JWIPC R19 boards share most of the same hardware key features and specifications: SoC – Rockchip RV1109 dual-core Arm Cortex-A7 @ 1.5 GHz, plus RISC-V MCU @ 400 MHz, […]

Security Tip – How to detect Juice Jacking on Android smartphones

A few years ago I wrote about the danger of “juice jacking” highlighting the security risks posed by USB charging in public places, where a bad actor could attempt to hack your phone or laptop to steal your precious data or install malware/ransomware. In most cases, there are no risks at home, but it’s when you charge your device in a public place notably an airport or train station that you could be at risk of hacking. If you’re using an Android phone, there’s an easy way to detect Juice Jacking, and whether something fishy is going on as shown in the screenshots below. On the left screenshot, I connect my phone to a USB charger, all that changed was the battery icon changed to show it’s charging. But on the right screenshot, I connected my smartphone to my laptop, and since it’s trying to access data, I’m offered three […]
