  • Finally Landed on Planet GNOME

    Should I start with a deep introduction? Not sure! Okay, let me start from my first time with Linux. I installed my first Linux when I was around 17, It was OpenSUSE. I just burned iso and booted, HAHAHA It was a magnetic disk era. After some years I was getting deep into Linux. I consider Linux as an Icecream. Lots of flavors to eat. Eat whatever you like. Or make your own flavor. 4-5 years ago I was jumping over multiple distros. I tried multiple linux distros. But now I'm settled on a custom build Debian distro. My first encounter with GNOME was on Fedora. I still love Fedora. But Debian is ultra-fast with only selected packages and easy to make its flavor. This is my short Linux story.

  • Sound Recorder to modern HIG I

    I'm back, reporting here what's done so far. I decided to post about every change in sound recorder I'm working on but most of the work was behind a scene. I mean no UI change.

    But now new changes noticeable to end-users.

    I'm also writing this development blog cause, I don't wanna give chance to other people to spread some false information about development around (Social Media, YouTube).

    If you are reading this and you are working on any GNOME project, Please take 5-6 min and write about it frequently.

    As I told I'm working on GNOME Sound Recorder, recently I changed many things in the application.

  • LibreOffice Tuesday T&T: Impress Presenter Screen

    LibreOffice Impress is a valuable presentation software, with plenty of advanced features. One of the most liked by skilled presenters is the so called Presentation Screen, which shows the current and the next slide on screen, and the notes. It helps the presenter to maintain the rythm of the presentation, and to remember the details of the talk.

    According to LibreOffice default configuration, the Presenter Screen shows only if the PC is connected to two displays. For some people this is a feature, for some others this is a bug.

  • PeaZip 7.3.1

    PeaZip is an open source file and archive manager. It's freeware and free of charge for any use. PeaZip can extract most of archive formats both from Windows and Unix worlds, ranging from mainstream 7Z, RAR, TAR and ZIP to experimental ones like PAQ/LPAQ family, currently the most powerful compressor available.

  • How CHAOSS Measures Open Source Community Health

    To learn more about the project, we spoke with Dawn Foster, Director of Open Source Community Strategy at VMware and member of the CHAOSS governing board.

    FOSSlife: Please give our readers a bit of background on the CHAOSS project. How did it originate and what are its goals?

    Dawn Foster: The community was formed as a result of a Birds of a Feather at the Linux Foundation Open Source Leadership Summit in 2017 out of a shared desire to collaborate on ways to measure open source project health. It was officially announced as a Linux Foundation project a few months later at the LF Open Source Summit North America. The idea was to bring together several different analytics tools, like GrimoireLab and cregit, into a coordinated effort while also developing metrics definitions that could be used by any implementation.

    [...]

    Dawn Foster: Anyone can participate in the CHAOSS project! I think sometimes people think that CHAOSS is all about software development on the tools we use to gather the metrics, and while that's an important part of what we do, it isn't everything. Most of the time, the working groups are discussing and defining metrics, which is something anyone can do.

    We collaboratively work together in documents to define metrics to better understand what questions they answer and why they are important in addition to talking about what data you might need to collect. In some cases, like with many of the diversity and inclusion metrics, qualitative measurements are an important element of the metrics definitions. We need people from all backgrounds with different skills to help us define metrics in a way that is useful for a variety of people and organizations.

    In addition to the metrics, CHAOSS is a fun community of smart and welcoming people, so it's a place where you can enjoy contributing!

  • NVIDIA K8s Device Plugin for Wind River Linux

    The advent of containers has changed the way computational workloads are managed and orchestrated in modern computing environments. Given the paradigm shift towards the microservices, container orchestration has become of critical importance in today’s distributed and cloud systems [1].

    Managing edge devices on the scale of hundreds and thousands is an onerous task. Fortunately, orchestrators such as Kubernetes take the complexity out of updates, roll-backs, and more in a platform-agnostic environment. [2]. Orchestrators provide the means to manage heterogeneous edge clusters. It is necessary to not only orchestrate containers but to discover the hardware specialized devices that the containers and orchestrator can leverage. Failing to manage these resources can lead to inefficiency, time drain, concurrency issues, and more.

Mozilla: Rustup 1.22.0, Servo and Performance Improvements via Formally-Verified Cryptography in Firefox

    • Announcing Rustup 1.22.0

      The rustup working group is happy to announce the release of rustup version 1.22.0. Rustup is the recommended tool to install Rust, a programming language that is empowering everyone to build reliable and efficient software.

    • This Week In Servo 131

      Welcome back everyone - it’s been a year without written updates, but we’re getting this train back on track! Servo hasn’t been dormant in that time; the biggest news was the public release of Firefox Reality (built on Servo technology) in the Microsoft store. In the past week, we merged 44 PRs in the Servo organization’s repositories.

    • Performance Improvements via Formally-Verified Cryptography in Firefox

      Cryptographic primitives, while extremely complex and difficult to implement, audit, and validate, are critical for security on the web. To ensure that NSS (Network Security Services, the cryptography library behind Firefox) abides by Mozilla’s principle of user security being fundamental, we’ve been working with Project Everest and the HACL* team to bring formally-verified cryptography into Firefox. In Firefox 57, we introduced formally-verified Curve25519, which is a mechanism used for key establishment in TLS and other protocols. In Firefox 60, we added ChaCha20 and Poly1305, providing high-assurance authenticated encryption. Firefox 69, 77, and 79 improve and expand these implementations, providing increased performance while retaining the assurance granted by formal verification.

Stable Clonezilla live 2.6.7-28 Released

This release of Clonezilla live (2.6.7-28) includes major enhancements and bug fixes.
ENHANCEMENTS and CHANGES from 2.6.6-15

  • The underlying GNU/Linux operating system was upgraded. This release is based on the Debian Sid repository (as of 2020/Jun/30).
  • Linux kernel was updated to 5.7.6-1.
  • ocs-iso, ocs-live-dev: sync syslinux-related files when copying syslinux exec files.
  • When creating recovery iso/zip file, if it's in Clonezilla live environment, we have those syslinux files. Use that first so the version mismatch can be avoided. Ref: https://sourceforge.net/p/clonezilla/support-requests/127/
  • Move grub-header.cfg from bootx64.efi to grub.cfg so that it's more flexible.
  • To avoid conflict with the patch of grub in CentOS/Fedora, for GRUB EFI NB MAC/IP config style, the netboot file is now like grub.cfg-drbl-00:50:56:01:01:01 and grub.cfg-drbl-192.168.177.2 not grub.cfg-01-* anymore.
  • Add xen-tools
  • Partclone was updated to 0.3.14. The codes about xfs was updated to be 4.20.0.
  • Package exfat-fuse was removed since the kernel has module for that.
  • A better mechanism to deal with linuxefi/initrdefi or linux/initrd in the grub config was added.

Pico-ITX board based on i.MX8M ships with Linux BSP

F&S has launched a $407 and up “armStone MX8M” Pico-ITX SBC that runs Linux on an i.MX8M with up to 8GB LPDDR4 and 64GB eMMC with GbE, WiFi/BT, 5x USB, MIPI-CSI, DVI, and a mini-PCIe slot. F&S Elektronik Systeme originally announced the NXP i.MX8M-based armStone MX8M Pico-ITX board in early 2018 with an intention to begin sampling in Q2 of that year. The i.MX8M-based SBC has finally arrived, selling for 360 Euros ($407) in a kit that includes cables, a Yocto/Buildroot BSP, and full access to documentation. The key new addition since the 2018 announcement is a mini-PCIe slot and SIM card slot. Instead of supplying 4x USB 2.0 host ports, you get 2x USB 3.0 and 2x USB 2.0, and the micro-USB OTG port has been updated from 2.0 to 3.0. Read more
