  • [LibreOffice GSoC] Week 4 Report

    The last week was the 4th week of coding weeks in GSoC program. So this report is final report before phase 1 evaluation . I continued adding support for the non supported items.

  • LibreOffice GSoC Week 4 Report

    Finally, the patch I worked on is merged thanks to my mentor(Muhammet Kara). You can easily access the patch, from here Last Week I marked this feature as an experimental feature. Hamburger button(gear button) is added. Some arrangements have been made for translation in UI elements. There was an error with iOS and Android build. But this problem is solved thanks to Tor Lillqvist and Miklos Vajna. There is a bug with Customize Dialog.

  • Draft of my perf book is ready!

    It has been a long journey! I was silent for a while, haven’t posted regularly on my blog. But don’t worry, I’m fine. Instead, I took this situation around coronavirus and focused on writing a book “Performance Analysis and Tuning on Modern CPU”. I started writing this book almost a year ago, so I’m happy I finally can show something to the people. Right now, the early draft is ready and I’m welcoming everybody to review the book and maybe even add something to it. I know a lot of people are struggling right now, so I decided to make the book FREE for all. Eventually, everyone will be able to download PDF version of it.

  • Daniel Stenberg: curl ootw: –remote-time

    --remote-time is a boolean flag using the -R short option. This option was added to curl 7.9 back in September 2001.

  • 6 ways HTTP/3 benefits security (and 7 serious concerns)

    HTTP3, the third official version of hypertext transfer protocol (HTTP), will not use the transmission control protocol (TCP) as did its predecessors. Instead, it uses the quick UDP internet connections (QUIC) protocol developed by Google in 2012.

    QUIC is a transport layer protocol based on a multiplexed version of user datagram protocol (UDP) connections. Unlike TCP, UDP does not follow the TCP three-way handshake, but uses a single UDP roundtrip. Thus, the QUIC protocol exponentially improves any web component's network performances as it uses UDP for every connection between the user-agent and the web server. Also, QUIC relies on multiplexing to manage multiple interactions between the user-agent and server seamlessly over a single connection, without any one blocking another, thus helping with performance improvements compared to its predecessors.

  • Practical Open Source Training from ASC Praktijkleren

    FOSSlife: Please give our readers a brief background of Stichting Praktijkleren. How did this organization get started and why?

    Hans Blankendaal: Stichting Praktijkleren is the Academy Support Centre (ASC) in the Netherlands that promotes up-to-date ICT skills in education. Stichting Praktijkleren is a national foundation with 43 academies as members, and it delivers materials for 4,500 teachers and 60,000 students. It came about in 2006 through the initiative of several regional training centers. As of 2018, the activities of the former Netherlands Academy Support Centre have been transferred to Stichting Praktijkleren and continued under the name of ASC Praktijkleren.

    Generally, ASC Praktijkleren supports regional training centers in the field of in-school and out-of-school work-based learning. In collaboration with the teachers at these training centers, Stichting Praktijkleren develops examination products and vocational learning materials and provides support for both students and teachers in the form of advice and mentoring, training, workshops, and conferences.

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

  • Fedora program update: 2020-28

    Here’s your report of what has happened in Fedora this week. The Nest With Fedora Call for Participation is now open. I have weekly office hours in #fedora-meeting-1. Drop by if you have any questions or comments about the schedule, Changes, elections, or anything else.

  • 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.

  • Light OpenStreetMapping with GPS

    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.
