Top Programming Languages & Operating Systems for the Internet of Things

The Eclipse foundation has recently done its IoT Developer Survey answered by 713 developers, where they asked  IoT programming languages, cloud platforms, IoT operating systems, messaging protocols (MQTT, HTTP), IoT hardware architectures and more.  The results have now been published. So let’s have a look at some of the slides, especially with regards to programming languages and operating systems bearing in mind that IoT is a general terms that may apply to sensors, gateways and the cloud, so the survey correctly separated languages for different segments of the IoT ecosystem. C and C++ are still the preferred languages for constrained devices, and developers are normally using more than one language as the total is well over 100%. IoT gateways are more powerful and resourceful (memory/storage) hardware, so it’s no surprise higher level languages like Java and Python join C and C++, with Java being the most used language with 40.8% […]

Zidoo X10 Android & OpenWrt TV Box with 3.5″ SATA Bay Sells for $229

Zidoo has sold two TV boxes based on Realtek RTD1295 so far with Zidoo X9S and Zidoo X8, and the company has done a pretty good job based on my review of Zidoo X9S. Both models run Android 6.0 with HDMI input recording and broadcasting functions, as well as OpenWrt for NAS functions, with X8 model relying on USB 3.0 storage, and X9S adding an external SATA port. It would be nice to have a model with an internal SATA bay, and it’s exactly what Zidoo X10 brings to the table. Zidoo X10 specifications with highlights in bold showing differences with Zidoo X9S: SoC – Realtek RTD1295 quad core Cortex A53 processor with ARM Mali-T820 MP3 GPU System Memory – 2GB DDR3 Storage – 16GB eMMC flash + micro SD slot up to 32GB + SATA 3.0 bay for 3.5″ hard drives Video I/O – HDMI 2.0a output up to […]

GnuBee Personal Cloud 1 Low Cost Linux NAS Supports Up to Six 2.5″ SATA Drives (Crowdfunding)

Networked Access Storage (NAS) with a large number of SATA bays usually cost several hundreds dollars up to thousands of dollars depending on the features set and performance, but there’s a new a project called GnuBee Personal Cloud 1, or GB-PC1, that delivers a MIPS Linux system supporting up to six 2.5″ SATA drives for less than $200.

LEDE 17.01.0 “Reboot” Router Operating System Released

LEDE (Linux Embedded Development Environment) is a fork of OpenWrt after some disagreements between developers, and while there are talks about merging OpenWrt and LEDE development, this is not done yet, and LEDE 17.01 has been released a few days ago. Some of notable LEDE 17.01 changes include: Linux kernel updated to version 4.4.50 (from 3.18 in Chaos Calmer) Update to dnsmasq 2.76, busybox 1.25.1, mbedtls 2.4.0, openssl 1.0.2k Improved Security Features Improved Networking Support Added new targets: apm821xx (AppliedMicro APM821xx) arc770 (Synopsys DesignWare ARC 770D) archs38 (Synopsys DesignWare ARC HS38) armvirt (QEMU ARM Virtual Machine) ipq806x (Qualcomm Atheros IPQ806X) layerscape (NXP Layerscape) zynq (Xilinx Zynq 7000 SoCs) Reorganized x86 target – Drop dedicated Xen DomU target, merged with x86/generic * Enable AES-NI support Build system improvements Image Builder / SDK – Rework library bundling to allow for better portability between different Linux distributions, added support for building kernel modules […]

Beelink SEA I Android TV Box, and HDMI Recorder Review – Part 1: Unboxing and Teardown

Realtek RTD1295 SoC is so far found in devices running Android & OpenWrt, and equipped with an HDMI input port for recording, PiP, and UDP broadcasting. I have already reviewed Zidoo X9S with an external SATA port, and Eweat R9 Plus with a 3.5″ SATA bay, and I’ve now received Beelink SEA I offering another option thanks to 2.5″ SATA bay, and a lower price of $98.99 and up using coupon GBSEA16 with the 2GB/16GB version, or GBSEA32 with the 2GB/32GB version. As usual, I’ll start with some photos and a teardown in the first part of the review, before testing the firmware in more details.

Baikal T1 BFK 1.6 MIPS Development Board Tested with OpenWrt

Baikal Electronics is a Russian fabless semiconductor company specializing in ARM and MIPS-based SoC, and we’ve already covered their Baikal T1 MIPS SoC announcement, as well as Tavolga Terminal TP-T22BT Debian 8 All-in-One Computer based on the processor. The company also have Baikal T1 BFK 1.6 development board, which does not appear to be publicly available yet, but one member of Habrahabr.ru forums got hold of one sample, and tested the OpenWrt SDK in Debian 8 host computer. First, we’ll have a look at the hardware they received. I don’t have the full specs of the board, but we’ll learn a little more below, in the meantime we can see two USB ports, Gigabit Ethernet ports, a 10GbE SFP cage, an mPCIe slot (I think), and two DB9 connector, as well as a bunch of other headers and connectors with SATA, GPIO, UART, I2C, SPI… I’ve then downloaded Baikal T1 BSP […]
