  • Linux 5.9 Likely To See USB4 Support Improvements

    Linux 5.6 brought initial USB4 support that primarily was starting things off by basing things off the existing Thunderbolt 3 support in the kernel for which this latest USB standard is based. For the Linux 5.9 kernel later this summer it's looking like there will be further work on getting Linux's USB4 support into good shape ahead of hardware appearing in the months ahead.

    Via the Thunderbolt bleeding-edge branch has been a number of USB4 patches building up over the past week. Intel's Mika Westerberg, Kranthi Kuntala, and Rajmohan Mani have been working on these latest USB4 additions.

  • Linux 5.8 Bringing Some Performance Boosts For AMD Renoir Graphics

    Over the weekend I began running some benchmarks of the Linux 5.8 development kernel on the Lenovo Flex 5 laptop with Ryzen 5 4500U. One of the standouts so far for from this Linux 5.8 testing compared to the stable 5.6/5.7 kernel series is better Radeon graphics performance with the Renoir laptop.

  • Linus Torvalds on the future of Linux kernel developers and development

    The illustrious pair started with Hohndel asking about the large size of the recent Linux kernel 5.8 initial release. Hohndel wondered if it might have been so big because developers were staying home thanks to the coronavirus. Torvalds, who always worked at home, said, "I suspect 5.8 might be [so large] because of people staying inside but it might also be, it's just happened that several different groups ended up coming at roughly the same time, with new features in 5.8."

    While COVID-19 has slowed down many technologies, while speeding up other tech developments, it hasn't affected Linux development much at all. "None of my co-developers have been hugely impacted either. I was worried for a while because one of our developers was offline for a month or two. … [But,] it turned out that it was just RSI [repetitive strain injury], and RSI is kind of an occupational hazard to deal with." He added. "One of the things that is so interesting about the Linux community is how much it has always been email-based and remote, how rarely we get together in person."

    In any case, Torvalds trusts this new build. Indeed, he ran his end of the videoconference from his new developer machine running the first release candidate of 5.8.

LibreOffice 7: Why a paid enterprise edition could be a positive change

The RC1 candidate of LibreOffice was recently released. Soon after, something odd was discovered in the About LibreOffice window. It seems the developers had tagged that release candidate as a Personal Edition. What did this mean? Of course speculation is running amok with rumors that LibreOffice is no longer going to be free. After all, the open source office suite has always been free and never before hinted at ever not being free. Yet, there was that oh-so-obvious change in the About dialog indicating something was amiss. After all, it's a pretty easy conclusion to draw when said dialog clearly states (Figure A): "The Personal Edition is supported by volunteers and is intended for individual use." Read more

  • openSUSE Tumbleweed – Review of the week 2020/28

    This week I have been fighting a bit with the size of the DVD. Due to some mistake in the pattern definition, it was for a good chunk ignored. Serves me right for fixing the error and then getting an ISO file that would not ever fit on a DVD, eh? Well, long story short: I needed to save some space, so looked at what the ‘fix’ newly brought on the DVD and aligned to what the DVD looked like before.

  • Nour E-Din ElNhass: An Appointment Up the Hill

    In my last post I showed screenshots for contacts appearing in Evolution, and explained that the .source file was created manually and that the credentials were hard coded for retrieving a specific journal form a specific EteSync account. After finishing this, I extended so that I can also retrieve calenders and tasks in the same manner which was quite easy as I already understood what should be done. Then I created an etesync-backend file, which generally handles the user’s collection account in evolution (retrieving/ creating /deleting) journals which are address-book or calenders .source files. The next step was then to make a user enter his credentials, So it isn’t hard coded. In this stage I had faced some issues regarding the implementation, I asked for my mentors help. Some of the problems that I faced were I needed to create a new dialog that will appear ask the user for his credentials and retrieve the data from EteSync, this had some implementation problems for me at first. Other issues appeared while integrating had to change some pieces.

    We're happy to announce Kiwi TCMS version 8.5! [...] Our website has been nominated in the 2020 .eu Web Awards and we've promised to do everything in our power to greet future FOSDEM visitors with an open source billboard advertising at BRU airport.

  • What is Application Definition?

    Application definition is the process of creating a codified operational runbook. It formalizes the process of describing in code everything an application needs to be built, run, and managed.

  • Open source contributions face friction over company IP

    Now, the overwhelming majority -- more than 90% -- of proposed open source contributions are approved by the council, said Nithya Ruff, the head of the Comcast open source program office. Under the current advisory council process, once engineers are approved to contribute to existing projects, they can make further contributions without having to go through the process all over again, according to Ruff. The process typically takes a few days at most. And since 2016, Comcast has donated several entire projects to open source, such as its Traffic Control CDN and Web PA client-server interface.

  • Virtualization Is Key to the Future of IT. Therefore ... What?

    If you look at commercial servers around the world, including those that provide the cloud in all its many forms to consumers of cloud-based infrastructures, platforms, services, and applications, you’ll soon learn that the vast majority of them run some version of Linux on the hardware, and consume a great many more Linux-based VMs than Windows-based ones. Even Microsoft has had to become more catholic in its approach: Today, its Azure cloud environment spawns Linux and Windows VMs with equal facility. Windows 10 has also become ever more accommodating of Linux, thanks to the Windows Subsystem for Linux (WSL) support for Linux within the Windows OS, along with Hyper-V’s ability to accommodate both Linux and Windows VMs. Specific versions of Linux have been developed as “network operating systems” that run on switches, and provide fully virtualized complex, networking environments. Thus, for example, Nvidia subsidiary Cumulus Networks offers a free virtual appliance called Cumulus VX that runs on KVM (a Linux-based or bare-metal hypervisor), Virtualbox (from a provider or as a local hypervisor), and Vagrant (from a libvirt provider). Cumulus Networks’ offering is based around Cumulus Linux, which adds a Network Command Line Utility (NCLU) to the basic Linux environment. This supports configuration, provisioning, and virtualization of network switches to support fully virtualized network infrastructures and let people learn about complex routing protocols such as BGP, XBGP, OSPF, and so forth. Other network players also offer virtualized toolsets and learning environments for their networking products and services as well, so they’re worth looking into as well, if networking is your thing.

  • Docker partners with AWS to smooth container deployments

    Docker containers, of course, can be used anywhere. But while developers may use Docker Desktop and the Docker CLI for building applications on their desktop, they may also have used Docker Compose to define and run multi-container applications via a YAML file. So far, so good. The problem is that there hasn't been a simple seamless way to use Docker and deploy to AWS from their desktop. That's because essential Amazon ECS constructs were not part of the Docker Compose specification. For instance, to run even a simple Compose file and deploy to ECS, developers are required to leave Docker tools and configure an Amazon VPC, Amazon ECS Cluster, and Amazon ECS Task Definition.

  • Linux networking - A weird little problem with DNS, DHCP

    At this point, or rather, just before this point, I was inclined to blame systemd. But it turns out, there's nothing wrong with it. Now, there were/are bugs in it, which is why it comes up quite high if you search for any connectivity problems in Linux.

    Now that lockdown is lifting a bit in Scotland, I’ve been going a bit further for exercise. One location I’ve been to a few times is Tyrebagger Woods. In theory, I can walk here from my house via Brimmond Hill although I’m not yet fit enough to do that in one go. Instead of following the main path, I took a detour along some route that looked like it wanted to be a path but it hadn’t been maintained for a while. When I decided I’d had enough of this, I looked for a way back to the main path but OpenStreetMap didn’t seem to have the footpaths mapped out here yet. I’ve done some OpenStreetMap surveying before so I thought I’d take a look at improving this, and moving some of the tracks on the map closer to where they are in reality. In the past I’ve used OSMTracker which was great, but now I’m on iOS there doesn’t seem to be anything that matches up.
