  • 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.

  • Kiwi TCMS 8.5

  • 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.

Flash ISOs to Multiple USB Sticks on Linux with Popsicle

This handy tool, which is written in Rust, lets you write an .iso (or other compatible image file) to more than one USB stick, SD card, or external drive at the same time. If you’ve been tasked with preparing multiple flash drives for your favorite OS to hand out to attendees at an event or the like then this would certainly be useful. But even if your needs aren’t as demanding as that being able to prep two installers, e.g., an SD card and a USB stick, to work with two different devices is made easier by this tool. Read more

Pantheon Desktop Review: A Beautiful Alternative to macOS

The Pantheon Desktop is designed specifically for elementaryOS and is considered one of the most visually appealing desktops around. It clearly draws a lot of inspiration from macOS, which makes it a great alternative for those who are looking to make the switch or who have always wanted to master that workflow. In this Pantheon Desktop review, I take a look at user experience and performance, as well as some notable features, and deciding who should use the Pantheon desktop. Read more
