IKOULA hosts Raspberry Pi 4 “micro server” for 4.99+ Euros per month

Filed under
Debian
Ubuntu

Hosting services for Arm single board computers where you pay a monthly fee for a board, and have it hosted in a datacenter with Internet access and easy provisioning have been around for over six years.

Last summer, we reported that Mythic Beasts and mini Nodes had added Raspberry Pi 4 hosting plans to their offerings, and others commented there were also other companies. But I’ve just been informed IKOULA, a hosting company based in France, had introduced Raspberry Pi 4 “micro server” hosting plans starting at just 4.99 Euros ex. VAT per month.

Hands-On: Adventures with Ubuntu Linux on the Raspberry Pi 4

Filed under
Linux
Ubuntu

With the introduction of the Raspberry Pi 4 series, with more than 1GB of memory, it has become much more practical to install and run Linux distributions other than the standard Raspberry Pi OS (formerly known as Raspbian). So it's time for me to give Ubuntu a try again, and see how it goes.

The first part of this task is simply deciding what version of Ubuntu to install – and that is nowhere near as easy as it sounds. Those who are familiar with Ubuntu and the RPi will know that the Ubuntu Mate project has had a Raspberry Pi version for quite some time, while the "official" Ubuntu Raspberry Pi distribution has only come out recently, and is only available for the Raspberry Pi 4. I will be looking at both of these.

Ubuntu maker wants app developers to stop worrying too much about security

Filed under
Security
Ubuntu

Buoyed by the recent Snyk security report that found security vulnerabilities in several container images except Ubuntu’s, the company behind it, Canonical, has published a whole portfolio of hardened images.

Unsurprisingly, Canonical has partnered with Docker to streamline the delivery of the secure portfolio of images through Docker Hub.

“Canonical and Docker will partner together to ensure that hardened free and commercial Ubuntu images will be available to all developer software supply chains for multi-cloud app development,” Docker's Matt Carter wrote in a blog post announcing the collaboration.

Torsten Franz: My first month at the Ubuntu Community Council

Filed under
Ubuntu

In the last few weeks I have been asked by many people what topics we have in the Community Council and what we are doing. After a month in the Council, I want to give a first insight into what happened in the early days and what has been on my mind. Of course, these are all subjective impressions and I am not speaking here from the perspective of the Community Council, but from my own perspective.

In the beginning, of course, we had to deal with organisational issues. These include ensuring that everyone is included in the Community Council’s communication channels. There are two main channels that we use. On the one hand, we have a team channel on IRC on Freenode to exchange ideas. The channel has the advantage that you can ask the others small questions and have a relaxed chat. To reach everyone in the Council, we have set up the mailing list: community-council at lists.ubuntu.com

No, I haven’t yet managed to read through all the documents and threads that deal with the Community Council or how to make the community more active again. But I have already read a lot in the first month on the Community Hub and on mailing lists to get different impressions. I can only encourage everyone to get involved with constructive ideas and help us to improve the community of Ubuntu.

I haven’t worked on an international board since 2017 and had completely forgotten one topic that is more complex than national teams: the different timezones. But after a short time we managed to find a date where we all can basically do it and we had our public meeting of the council. This took place twice and the second time we all managed to attend. The minutes of the meetings are publicly available: 1st Meeting and 2nd Meeting. We have decided that we will hold the meeting twice a month.

Ubuntu Linux maker Canonical publishes curated container images to help secure software supply chains

Filed under
Linux
Ubuntu

A good deal of software development now relies on open source images, but it can be hard for businesses to know if they're introducing security flaws by using them.

Canonical -- the company behind Ubuntu Linux -- is addressing this by publishing the LTS (Long Term Support) Docker Image Portfolio, a curated set of secure container application images, on Docker Hub.

LTS Images are built on trusted infrastructure, in a secure environment, with guarantees of stable security updates. Canonical and Docker will collaborate on Docker Official Images and the LTS Docker Image Portfolio to bring the best of the two to the community and ecosystem. The entire LTS Docker Image Portfolio will also be exempted from per-user rate limits.

Reolink RLC-810A review – A 4K security camera with people & vehicle detection

Filed under
Android
Reviews
Ubuntu

The person and vehicle detection feature in Reolink RLC-810A security camera is just great, and I could not imagine reviewing other CCTV cameras or NVR systems without AI in the future, as in my experience, standard motion detection just does not cut it with too many false positive. As we’ve seen in the review, the way to position the camera may be important to make sure it works optimally, and at night, cats may be detected as persons, but it still removes 99% of the noise I got with PIR sensors.

I don’t like using Windows, simply because I only use Ubuntu 20.04 on my laptop and Android on my phone unless I have no other choice. So I also really appreciated the multiple ways I could access the camera from the Android app and a standard web browser in Ubuntu, and support for RTSP and ONVIF is also great for people wanting to integrate the camera into their own CCTV solution. It should be noted I could only access the “Clear” 4K UHD stream from the Android app (it should also work in Reolink Windows and Mac program), and RTSP, but only the “Fluent” 640×360 stream from the web browser and ONVIF, so that’s probably something the company will want to fix in a new firmware update.

Besides working on the Ubuntu Touch mobile OS, which was discontinued by Canonical a few years ago, UBports Foundation also works on other cool things to make it easier for users to migrate to a Linux phone from Android or iOS.

One of these is the UBports Installer or the official Ubuntu Touch Installer, which lets you install Ubuntu Touch on any of the supported devices without minimal effort. The best part is that you don’t even need Linux to use the Ubuntu Touch Installer since it works on macOS and Windows computers too.

Web
Ubuntu

It’s been over four months since I reported about the arrival of yet another Ubuntu-based Linux distribution called Ubuntu Web Remix.

So, if you were also waiting for it just like me, the wait is over because its creator, Rudra Saraswat, has finally announced and made its first stable release, Ubuntu Web Remix 20.04.1, available to download.

To remind you, after Ubuntu Unity and UbuntuEd, Ubuntu Web is the third unofficial Ubuntu remix distros by the same developer Rudra Saraswat.

Unlike the other two, Ubuntu Web Remix aims to be a web-centric operating system and an alternative to Google’s Chrome OS or Chromium OS.

  • Fanless Linux embedded system makes a compact IoT gateway

    ICP Germany has recently introduced the MiTAC ME1-8MD series family of compact, fanless Linux embedded systems powered by NXP i.MX 8M processor and designed to be used as IoT gateways, data acquisition and processing systems, and mini servers. Three models have been launched with a choice of dual or quad-core processors, up to 4GB LPDDR4 RAM, and 32GB eMMC flash storage. The embedded computers also come with up to two Ethernet ports, support up to two displays, and include an internal Raspberry Pi compatible 40 pin GPIO header.

  • Official Raspberry Pi 4 case fan adds cooling to Raspberry Pi 4 case

    When the Raspberry Pi Foundation first introduced the Raspberry Pi 4, they claimed the board would work just fine under most cases without a heatsink, and the latter was only really needed under load. That may have been true when using the board in a temperate climate like in the United Kingdom, but then Raspberry Pi 4 met Thailand with some benchmarks results lower than on a Raspberry Pi 3. People using plastic enclosures had even more troubles. It’s only when I installed a heatsink on Raspberry Pi 4 that the board could really shine. The company also provided some firmware optimizations later on to further cool-down the board. But you can only do much with software, and many third-party cooling solutions such as fansinks or metal cases have been introduced for the popular SBC.

Linux Kernel: Greg Kroah-Hartman's Talk and Panics

  • Greg Kroah-Hartman: Lessons for Developers from 20 Years of Linux Kernel Work [Ed: "The Linux Foundation is a sponsor of The New Stack" for the latter to write puff pieces such as these, so it's basically marketing]
  • Greg Kroah-Hartman: 'Don't Make Users Mad'

    Kroah-Hartman explains that one of Linus Torvalds' most deeply-held convictions: don't break userspace. "Other operating systems have this rule as well — it's a very solid rule — because we always want you to upgrade. And we want you to upgrade without worrying about it. We don't want you to feel scared. If you see a new release, and we say, 'Hey, this fixes a bunch of problems,' we don't want you to feel worried about taking that. That's really really important — especially with security...." If you do make a change, make sure there truly is a compelling reason. "You have to provide enough reason and enough goodness to force somebody to take the time to learn to do something else. That's very rare." His example of this was systemd, which unified a variety of service configurations and initialization processes. "They did it right. They provided all the functionality, they solved a real problem that was there. They unified all these existing tools and problems in such a way that it was just so much better to use, and it provided enough impetus that everybody was willing to do the work to modify their own stuff and move to the new model. It worked. People still complain about it, but it worked. Everybody switched... It works well. It solves a real problem. "That was an example of how you can provide a compelling reason to move on — and make the change."

  • What to do in case of a Linux kernel panic

    Linux is used everywhere in the IT world. You've probably used Linux today, even if you didn't realize it. If you have learned anything about Linux, then you know it is indeed a kernel. The kernel is the primary unit of the Linux operating system (OS) and is responsible for communications between a computer's hardware and its processes. In this article, you will learn about one situation related to the Linux kernel: The kernel panic. The term itself can make you panic, but if you have the proper knowledge, then you can remain calm. Every system admin faces this issue at least once in their career, but reinstalling the system is not the first solution you should turn to. [...] Now, anytime you see a kernel panic error, you will definitely not panic because you know why this error occurred and how to resolve it. This article covers one of the common Linux boot problems: kernel panic. There are so many other potential boot problems that can occur in Linux, but resolving those issues will become much less of a panic when you gain some advanced knowledge of your system.
