  • Announcing BadISO

    For a few years now I have been working on-and-off on a personal project to import data from a large collection of home-made CD-Rs and DVD-Rs. I've started writing up my notes, experiences and advice for performing a project like this; but they aren't yet in a particularly legible state.

    As part of this work I wrote some software called "BadISO" which takes a possibly-corrupted or incomplete optical disc image (specifically ISO9660) and combined with a GNU ddrescue map (or log) file, tells you which files within the image are intact, and which are not. The idea is you have tried to import a disc using ddrescue and some areas of the disc have not read successfully. The ddrescue map file tells you which areas in byte terms, but not what files that corresponds to. BadISO plugs that gap.

  • MusE 3.0.0 released

    Three years after the last stable release, version 3.0 of the MusE MIDI/Audio sequencer is now available. As you might expect there many changes since the last release including a switch to Qt5, a new Plugin Path editor in Global Settings, a mixer makeover with lots of fixes, a system-wide move to double precision of all audio paths, and much more.

  • Linux Release Roundup: Wine, Soundnode, Etcher + More

    Welcome to our first Linux Release Roundup of 2018 — and as you might expect from the first week of a new year, there’s not an awful lot to round up!

    I like to assume that app developers spent their holidays enjoying themselves rather than beavering away on apps for our collective benefit.

    Even so, here are a couple of recent updates – but warning: this post contains Electron.

  • Interview with Emily K. Mell

    That it’s free! I think it’s remarkable that the open-source community could create something of this quality without a money spigot. Given Adobe’s outrageous pricing scheme for Photoshop, you’d think that software like this couldn’t exist anywhere else. Krita is a much better option.

  • Loving Gitlab.gnome.org, and getting notifications

    I'm loving gitlab.gnome.org. It has been only a couple of weeks since librsvg moved to gitlab, and I've already received and merged two merge requests. (Isn't it a bit weird that Github uses "pull request" and Everyone(tm) knows the PR acronym, but Gitlab uses "merge request"?)

  • 7 Best Alternatives To Microsoft Office Suite — 2018 Edition

    Some people need specific features or compatibility with other contacts, and that’s understandable; it’s expected to come at a price. But what about those who don’t need much out of an office software? The average person, even if technically inclined, doesn’t need much out of a word processor (I mean, it’s not like it’s a text editor or anything). So, should you pay for something that you don’t need? Probably none of my business, so I’ll just give you the facts to make an informed decision and select the best Microsoft Office alternative...

Kernel and Graphics: PDS, VKMS and Nouveau

  • PDS 0.98s release
    PDS 0.98s is released with the following changes 1. Fix compilation issue on raspberry pi. 2. Minor rework and optimization on balance code path. 3. Fix wrong nr_max_tries in migrate_pending_tasks. This is mainly a bug fix and minor optimization release for 4.17. The rework of balance code doesn't go well, it actually make more overhead than current implement. Another rework which based on current implement is still on going, hopefully be included in next release.
  • PDS-MQ CPU Scheduler Revised For The Linux 4.17 Kernel With Minor Optimizations
    Alfred Chen announced this week the release of PDS-mq 0.98s, his latest patch-set of this CPU scheduler against the Linux 4.17 upstream code-base and includes minor optimization work and bug fixes. The PDS scheduler stands for the "Priority and Deadline based Skiplist multiple queue scheduler" that is derived from Con Kolivas' former BFS scheduler with Variable Run Queue (VRQ) support. PDS design principles are to be a simple CPU process scheduler yet efficient and scalable. PDS-mq differs from Con Kolivas' current MuQSS scheduler.
  • Add infrastructure for Vblank and page flip events in vkms simulated by hrtimer
    Since the beginning of May 2018, I have been diving into the DRM subsystem. In the beginning, nothing made sense to me, and I had to fight hard to understand how things work. Fortunately, I was not alone, and I had great support from Gustavo Padovan, Daniel Vetter, Haneen Mohammed, and the entire community. Recently, I finally delivered a new feature for VKMS: the infrastructure for Vblank and page flip events. At this moment, VKMS have regular Vblank events simulated through hrtimers (see drm-misc-next), which is a feature required by VKMS to mimic real hardware [6]. The development approach was entirely driven by the tests provided by IGT, more specifically the kms_flip. I modified IGT to read a module name via command line and force the use of it, instead of using only the modules defined in the code (patch submitted to IGT, see [1]). With this modification in the IGT, my development process to add a Vblank infrastructure to VKMS had three main steps as Figure 1 describes.
  • The State Of The VKMS Driver, Preparations For vBlank & Page Flip Events
    One of the exciting additions to look forward to with the upcoming Linux 4.19 kernel cycle is the virtual "VKMS" kernel mode-setting driver. The driver is still a work-in-progress, but multiple developers are working on it.
  • NIR Continues To Be Prepped For OpenCL Support
    Longtime Nouveau contributor Karol Herbst who joined Red Hat several months ago has been working on Nouveau NIR support as stepping towards SPIR-V/compute support and this summer the work very much remains an active target.
  • Nouveau Gallium3D Moves Closer Towards OpenGL 4.5 Compliance
    While the RadeonSI and Intel i965 Mesa drivers have been at OpenGL 4.5 compliance for a while now, the Nouveau "NVC0" Gallium3D driver has been bound to OpenGL 4.3 officially. This Nouveau Gallium3D driver for NVIDIA "Fermi" graphics hardware and newer has effectively supported all of the OpenGL 4.4/4.5 extensions, but not officially. Originally the NVC0 problem for OpenGL 4.4 and newer was the requirement of passing the OpenGL Conformance Test Suite (CTS), which at first wasn't open-source. But now The Khronos Group has made it available to everyone as open-source. Additionally, the proper legal wrangling is in place so the Nouveau driver could become a conforming Khronos adopter under the X.Org Foundation without any associated costs/fees with Nouveau being purely open-source and primarily considered a community driver.

DistroWatch The Best Website For Distro Hoppers

The DistroWatch features release announcements of new versions of hundreds of Linux and other distributions. It does host reviews of distros, podcasts, and newsletters. DistroWatch first published by Ladislav Bodnar, the founder, and maintainer, on May 31, 2001. DistroWatch initially focused on Linux distributions. But later based on user requests, it went on adding different flavors of operating systems like BSD family, Android x86, Oracle Solaris, MINIX, and Haiku etc. The DistroWatch presents detailed information at one place in a very convenient manner. At the time of writing this article, the DistroWatch hosted information of more than 300 active distributions (referring the list of distros populated under drop-down feature on the first page of the DistroWatch) and more than hundred in queue. It is said that the DistroWatch lives out of advertising and donation. LinuxCD.org is the first to advertise on the DistroWatch site. Read more

Ubuntu 18.04 LTS and 16.04 LTS Amazon Linux AMIs Now Support Amazon's SSM Agent

As of July 2018, Amazon's Linux AMIs (Amazon Machine Images) that are based on either the Ubuntu 16.04 LTS (Xenial Xerus) or Ubuntu 18.04 LTS (Bionic Beaver) operating systems now come pre-installed with the AWS Systems Manager Agent (SSM Agent), an Amazon software designed to run on hybrid or Amazon EC2 instances in public and private clouds on AWS (Amazon Web Services). "With this new feature release, AWS Systems Manager Agent is installed by default on all instances launched or built from Ubuntu 16.04 LTS (2018.07 and later) and 18.04 LTS (all versions) AMIs," said Amazon. "By having the agent pre-installed, you can quickly start using AWS Systems Manager features such as Run Command, State Manager, Inventory and Patch Manager." Read more
