K3s Lightweight Kubernetes Distribution Targets Low Resources x86 and Arm Platforms

Kubernetes (K8s) is described as a “portable, extensible open-source platform for managing containerized workloads and services, that facilitates both declarative configuration and automation. It has a large, rapidly growing ecosystem. Kubernetes services, support, and tools are widely available. Google open-sourced the Kubernetes project in 2014”. However, as Rancher Labs’ CEO Sheng Liang explains “existing Kubernetes distributions are often memory intensive and overly complex for edge computing environments”, so the company developed and launched K3s, a lightweight Kubernetes distribution designed for developers and operators looking for a way to run Kubernetes in resource-constrained x86, Armv7-A and 64-bit Armv8-A hardware platforms often found in edge computing environments, as opposed to the cloud. Rancher Labs managed to reduce the footprint of Kubernetes, and better adapt it to entry-level hardware by taking four main steps: Removing old and non-essential code – Alpha functionalities, all non-default admission controllers, in-tree cloud providers, and storage drivers are […]

Build an ESP8266 IR Remote Control with LOLIN IR Controller Shield for D1 Mini Board

Infrared remote control are still widely with TVs, set-top boxes, air conditioners, and all other sort of appliances with the end result of having many remote control around the house. If you want to cut on the number of remote controls, there are several solutions: Get a smartphone with a Built-in IR transmitter like Xiaomi Mi A1. Add an IR transmitter to your smartphones’s headphone jack using ZazaRemote or USB type C port with ROCK USB type C IR transmitter. Get a WiFi IR blaster in order to control devices remotely, or maybe buy several try control any IR devices from anywhere DIY your own solution for more flexibility, for example using ANAVI Infrared pHAT and a Raspberry Pi board. The smartphone solutions (1 & 2) works as long as you are in the room, but the WiFI IR blaster allows you to control devices even if you are not […]

Recommended Products

With new products released every day, it’s easy to be overwhelmed by the choice, so I’ll provide purchase links to products that I’ve either tested, or are recommended by the community for TV boxes, mini PCs, 3D printers, Linux development boards,  MCU / IoT boards, and home automation products. To keep it simple, I’ll select up to 3 products in each category. TV Boxes I’ve already details some of the best TV boxes, and a list of criteria that are important when selecting a TV box in my post entitled What’s the Best Android TV Box (2017/2018 Edition)?, so I’ll provide purchase links to some of the best options. NVIDIA SHIELD Android TV for best Android TV and gaming experience around $200 on Amazon. MINIX NEO U9-H for a solid Android experience for 4K videos and audio-passthrough (not Android TV), around $150 on Amazon, GeekBuying, or GearBest.(MINIX NEO A3 air […]

FOSSASIA Summit 2018 Schedule – March 22-25

FOSDEM is the “Free & Open Source Software Developers’ European  Meeting” takes place the first week-end of February every year in Brussels, Belgium.  It turns out there’s an event in Asia called FOSSASIA Summit that’s about to take place in Singapore on March 22-25. There are some differences however, as while FOSDEM is entirely free to attend, FOSSASIA requires to pay an entry fee to attend talks, although there are free tickets to access the exhibition hall and career fair. There are also less sessions as in FOSDEM, but still twelve different tracks with: Artificial Intelligence Blockchain Cloud, Container, DevOps Cybersecurity Database Kernel & Platform Open Data, Internet Society, Community Open Design, IoT, Hardware, Imaging Open Event Solutions Open Source in Business Science Tech Web and Mobile Since the event is spread out over four days, it should be easier to attend the specific sessions you are interested in.

Embedded Linux Conference & IoT Summit 2018 Schedule

The Embedded Linux Conference 2018 and the OpenIoT Summit 2018 will jointly take place next month, on March 12 – 14, 2018 in Portland, Oregon, USA. The former is a “vendor-neutral technical conference for companies and developers using Linux in embedded products”, while the latter is a “technical conference for the developers and architects working on industrial IoT”. The Linux Foundation has already published the schedule, and it’s always useful to learn what will be discussed about even for people who won’t attend. With that in mind, here’s my own virtual schedule with some of the talks I find interesting / relevant to this blog. Monday, March 12 10:50 – 11:40 – Progress in the Embedded GPU Ecosystem by Robert Foss, Collabora Ltd. Ten years ago no one would have expected the embedded GPU ecosystem in Linux to be what it is now. Today, a large number of GPUs have […]

Review of GOLE 10 Mini PC with 10.1″ Touchscreen Display – Part 2: Windows 10 Pro

Depending on your point of view, GOLE 10 is a mini PC with a touchscreen display, or a really thick tablet with an inclined display.  I’ve already received a sample, and had a look at the hardware in the first part of the review, so in the second I tested the performance and stability, and thought about and test some use cases for this type of products. GOLE 10 (aka F6) Setup and System Info There are various way to use the mini PC, either as a standalone screen without any peripheral connected using the touchscreen, or as a mini PC with USB keyboard and mouse and potential other accessories, or in a dual display setup with the device connected to an HDMI TV or monitor. I decided to connect it to my “test” TV, add a USB 3.0 drive, USB keyboard and mouse, Ethernet cable, and of course the […]
