OpenSUSE’s OBS Can Now Spin Windows Subsystem for Linux Images

Monday 14th of October 2019 02:37:05 PM

The openSUSE’s Open Build Service (OBS) has been picking up the ability to build Windows Subsystem for Linux (WSL) images for those wishing to craft their own WSL distribution or just rebuild openSUSE from source as a reproducible/verifiable build. The complexity with spinning openSUSE WSL images in OBS is the appx files that need to be assembled, which they have relied upon using Microsoft Visual Studio from a Windows machine. But now in making use of the MinGW cross-toolchain they are generating the necessary appx files directly on Linux. (Phoronix)

SAP Embraces Serverless Computing Frameworks

Saturday 12th of October 2019 03:52:23 AM

SAP has begun to make available extensions to its cloud platform that enable customers to leverage a framework running on top of Kubernetes to invoke serverless computing frameworks. The framework is based on the open source Kyma project spearheaded by SAP. Thomas Grassl, vice president for developer relations and the SAP Community, says SAP expects developers to make extensive use of serverless computing frameworks running on public clouds to not only dynamically invoke additional compute resources when needed, but also reduce the size of their applications by relying on functions as a service to, for example, run an analytics process.

System76 launches two Linux with Comet Lake chips and Coreboot

Thursday 10th of October 2019 11:02:52 PM

Linux computer company System76 is updating its laptop lineup with its first two models to ship with 10th-gen Intel Core “Comet Lake” processors. The new 14 inch Galago Pro and 15.6 inch Darter Pro laptops also ship with the open source Coreboot firmware rather than a proprietary BIOS. As Phoronix points out, these laptops still have some Intel proprietary blobs, so it’s probably best to think of them as more open than most laptops rather than computers running 100-percent free and open source software.

Why Linux Developers Should Reconsider IBM Mainframes

Thursday 10th of October 2019 05:27:19 PM

When mainframes were mainstream, many software professionals in the industry today were not even born yet. Mainframe computers have an extensive history, which makes it tempting to call them old, but today’s mainframes are extremely mature, fast, reliable and powerful. In fact, they are critical to the modern economy: Top airlines, banks, insurance companies and health care corporations rely on mainframe computing.

One of the organizations keeping this technology with the times is IBM, with its IBM Z family of mainframe computers. Some of these mainframes—like the 31-bit s390 and, later, the 64-bit s390x architecture—were originally designed and built in the 1960s, and they have continued to evolve and modernize.

“IBM still sells a lot of these even today,” said Elizabeth K. Joseph, a seasoned open source advocate who recently joined IBM as the developer advocate for its Z architectures. These machines run operating systems including z/OS, z/VM, z/VSE and z/TPF, as well as Linux-based distributions like Red Hat Enterprise Linux and SUSE Linux Enterprise Server.

With Linux, mainframes can run modern languages, toolings and CI/CD pipelines. If it runs on Linux, it can run on Z.

Joseph gave one of her favorite examples of running Linux on Z. If someone is using encryption, they don’t have to install any binary blob from IBM to leverage the hardware encryption. It’s just a config file that can be added to openSSL. There are crypto processors on each processor, which give users access to these powerful encryption technologies.

However, mainframes still have an identity crisis. Most people think they don’t belong to the modern world dominated by x86 architectures, virtualizations and containers.

That’s the perception that Joseph is trying to change. One of her goals is to evangelize Z to modern Linux developers.

Why would Linux developers ditch the cloud or the omnipresent x86 platform and embrace Z? Joseph herself is an ideal example of a Linux and open source developer. She got attracted to Z for many different reasons, some technical and some rational.

First and foremost, she says that contrary to popular belief, the AWS cloud can become extremely expensive very quickly. “You can incur monthly bills in hundreds of thousands of dollars,” Joseph said. People have started to look at on-premises architectures as an alternative to AWS. However, they think that x86 is their only choice, which is far from true.

“You can use ARM if you need power efficiency, and you can use Z if you want uncompromised experience. X86 isn’t the only option people have,” she said.

Google made x86 popular; it used to be viewed as a cheap platform that was nonetheless unreliable and inefficient. Joseph recalls a discussion with one of her associates who said that “the world couldn’t survive the growth of these x86 farms.” When she asked whether he meant it was too expensive or bad for the planet, he said, “Both.”

It’s true that this mainframe is not x86. Developers have to port their applications to Z, the same way they port their applications to other architectures like ARM.

However, if you look at processing power, you have these separate, individual machines consuming massive amounts of resources. It’s much more economical and efficient to power and cool one mainframe as compared to thousands of x86 servers.

The same goes for software. Managing software on one mainframe is much more efficient and economical than managing it on thousands of x86 servers to get the same computation power.

The unending Spectre and Meltdown saga has rubbed salt in the wound. These exploits are not going away; it’s a design flaw in modern processors that allows programs to steal the data being processed on the computer. Mitigating these vulnerabilities results in heavy performance penalties.

“There can be exploits for any platform, but a user should not have to suffer heavily,” Joseph said.

She also said that she doesn’t believe in one particular option always being used over another; she thinks people should embrace diversification of architecture.

“If one platform goes down, you should be able to switch to something else without having to suffer any losses,” she said

On top of that, mainframes offer unmatched redundancy, something that’s critical in on-premises setups. “You can pull out the power, and there’s another power. If the CPU dies, there’s another CPU there. You get a storage array of hundreds of drives,” Joseph said. “In fact ‘Z’ stands for ‘zero downtime.’ These machines essentially never go down.”

Together, Z and Linux create a formidable force. They combine the best of the hardware and software worlds, creating an ideal platform to run modern workloads.

As part of her evangelism for Z, Joseph is offering Linux developers with virtual machines a mainframe that they can use for free for four months. “Just ssh into the mainframe and start using it,” she said.

As a developer herself, Joseph believes that a developer should target multiple architectures.

“It makes you a better programmer, as you don’t get so insulated into one platform.”

Zephyr RTOS 2.0 Release Highlights

Thursday 10th of October 2019 09:31:29 AM

Written by Ioannis Glaropoulos, Software System Architect at Nordic Semiconductor and active member of the Zephyr Technical Steering Committee

Last month, the Zephyr Project announced the release of Zephyr RTOS 2.0 and we are excited to share the details with you! Zephyr 2.0 is the first release of Zephyr RTOS after the 1.14 release with Long-Term support in April 2019. It is also a huge step up from the 1.14 release, bringing a wide list of new features, significant enhancements in existing features, as well as a large list of new HW platforms and development boards.

On the Kernel side, we enhanced the compatibility with 64-bit architectures, and significantly improved the precision of timeouts, by boosting the default tick rate for tickless kernels.

Additionally, we are excited to welcome ARM Cortex-R into the list of architectures supported in Zephyr RTOS.

A major achievement in this release is the stabilization of the Bluetooth Low Energy (BLE) split controller, which is now the default BLE controller in the Zephyr RTOS. The new BLE controller enables support for multi-vendor Bluetooth v5.0 radio hardware with a single controller code-base, thanks to a layered modular architecture, where most of the controller code is hardware agnostic. The new controller also features improved scheduling of continuous scanning and directed advertising, and increased radio time utilization. The latter significantly improves the achievable communication bandwidth – among other use-cases – in BLE Mesh networking.

In the networking area, we introduced support for SOCKS5 proxy, an Internet protocol that exchanges network packets between a client and server through a proxy server. In addition, we added support for 6LoCAN, a 6Lo adaption layer for Controller Area Networks, and for Point-to-Point Protocol (PPP), which is used to establish a direct connection between two nodes. We, finally, added support for UpdateHub, an end-to-end solution for large scale over-the-air device updates.

A most sincere thank you to the more than 215 developers who contributed to this release. Not only did you add a wealth of new features during the merge window, you also rallied together as a community during the stabilization period across time zones, companies, architectures, and even weekends, to find and fix bugs, to make Zephyr 2.0 yet another great release! This release would not have been possible without your hard work!

The Linux Mint 19.2 Gaming Report: Promising But Room For Improvement

When I started outlining the original Linux Gaming Report, I was still a fresh-faced Linux noob. I didn’t understand how fast the ecosystem advanced (particularly graphics drivers and Steam Proton development), and I set some lofty goals that I couldn’t accomplish given my schedule. Before I even got around to testing Ubuntu 18.10, for example, Ubuntu 19.04 was just around the corner! And since all the evaluation and benchmarking takes a considerable amount of time, I ended up well behind the curve. So I’ve streamlined the process a bit, while adding additional checkpoints such as out-of-the-box software availability and ease-of-installation for important gaming apps like Lutris and GameHub.

Something exciting is coming with Ubuntu 19.10

ZFS is a combined file system and logical volume manager that is scalable, supplying support for high storage capacity and a more efficient data compression, and includes snapshots and rollbacks, copy-on-write clones, continuous integrity checking, automatic repair, and much more. So yeah, ZFS is a big deal, which includes some really great features. But out of those supported features, it's the snapshots and rollbacks that should have every Ubuntu user/admin overcome with a case of the feels. Why? Imagine something has gone wrong. You've lost data or an installation of a piece of software has messed up the system. What do you do? If you have ZFS and you've created a snapshot, you can roll that system back to the snapshot where everything was working fine. Although the concept isn't new to the world of computing, it's certainly not something Ubuntu has had by default. So this is big news. Read more

Pack Your Bags – Systemd Is Taking You To A New Home

Home directories have been a fundamental part on any Unixy system since day one. They’re such a basic element, we usually don’t give them much thought. And why would we? From a low level point of view, whatever location $HOME is pointing to, is a directory just like any other of the countless ones you will find on the system — apart from maybe being located on its own disk partition. Home directories are so unspectacular in their nature, it wouldn’t usually cross anyone’s mind to even consider to change anything about them. And then there’s Lennart Poettering. In case you’re not familiar with the name, he is the main developer behind the systemd init system, which has nowadays been adopted by the majority of Linux distributions as replacement for its oldschool, Unix-style init-system predecessors, essentially changing everything we knew about the system boot process. Not only did this change personally insult every single Perl-loving, Ken-Thompson-action-figure-owning grey beard, it engendered contempt towards systemd and Lennart himself that approaches Nickelback level. At this point, it probably doesn’t matter anymore what he does next, haters gonna hate. So who better than him to disrupt everything we know about home directories? Where you _live_? Although, home directories are just one part of the equation that his latest creation — the systemd-homed project — is going to make people hate him even more tackle. The big picture is really more about the whole concept of user management as we know it, which sounds bold and scary, but which in its current state is also a lot more flawed than we might realize. So let’s have a look at what it’s all about, the motivation behind homed, the problems it’s going to both solve and raise, and how it’s maybe time to leave some outdated philosophies behind us.
