Quick Roundup

GNOME: GUADEC, GSoC, GitLab

  • Petr Kovar: GUADEC 2018
    Back from GUADEC, held in the beautiful Andalusian city of Almería, Spain, from 6th July through 11th July, 2018, I wanted to share a few notes wrt documentation and localization activities at the conference and during the traditional post-conference hacking days.
  • GUADEC18 Developer Center BoF Part 1: The Developer Experience
    At this year’s GUADEC lightning talks I spontaneously announced and arranged a Developer Center BoF (Birds of a Feather) session. We were six attendants who met together Wednesday the 11th September. I think it is important that we communicate our doings to the rest of the community, so I will make a few short blog posts based on our meeting notes and my own thoughts on the subject.
  • GSoC 2018: Safe Shared Access to Cairo Image Surfaces
    I’m working on librsvg, a GNOME SVG rendering library, to port the SVG filter effects and related infrastructure from C to Rust. Librsvg uses Cairo, a 2D graphics library, for most of its drawing operations. Cairo can draw to a number of different surfaces like XCB and Xlib windows and pixmaps, PDF documents and PostScript files.

OSS: Apache Cassandra, Jib,WSO2 and More

  • Apache Cassandra at 10: Making a community believe in NoSQL
    Ten years ago this month, when Lehman Brothers was still just about in business and the term NoSQL wasn't even widely known, let alone an irritant, Facebook engineers open-sourced a distributed database system named Cassandra. Back then, the idea that huge numbers of companies would need a scalable database was almost laughable – and that grip of traditional relational database systems is reflected in the mythical moniker given to what would become one of the first of many databases designed to run on a cluster of machines. Named after the Greek figure who was cursed to utter the truth but was never believed, Cassandra might seem an odd choice for a system whose raison d'être is believability – but it delivered a nice dig at the stalwarts of the RDBMS world… and their trust in a false Oracle.
  • Google Launches Jib, Automated Container Packaging for Java Apps
    Google has released software that could automate the packaging of a Java program so that it can be run in the cloud-native environment. Jib is an open-source Java “containerizer,” one that handles all the steps of packaging your application into a container image, according to Appu Goundan and Qingyang Chen, two Google engineers who co-wrote a blog post announcing the new technology. Created over two decades ago at Sun Microsystems, Java was introduced as a “write once, run anywhere” programming language, where all the code would be packaged in a JAR file, and run by a Java Virtual Machine on any platform. The requirements for running code anywhere have expanded with the introduction of containerization, however. Few shops are Java-only these days, and many are turning to containerization for true application portability,

I also have to release pgpainless to maven central and establish some kind of release cycle. It will be a future challenge for me personally to synchronize the releases of smack-openpgp and pgpainless.
  • Collaborative World Shaping: Why Open-Source Tech Matters in a For-Impact Future
    How many lives could be saved if there was a way to vastly cut down inefficiency and through bureaucracy, by problem solving at a global scale? Could technology help us reach more individuals in need more meaningfully, substantially helping people affected by disasters – in less time? The technology is already out there – but not enough people know about it. In 2017, Hurricane Irma—the strongest hurricane ever recorded in the Atlantic Ocean—made landfall; with widespread, “catastrophic” damage, disaster relief organizations were overwhelmed. “A lot of traditional means of crisis response are very top down, and they didn’t really kick in — we saw headlines about how the Red Cross didn’t show up to shelters,” said Greg Bloom, a community organizer and civic hacker who knew he had to step in to assist.
  • The First Open-Source Smart Contract Platform to be Started by Rootstock
    RSK Labs, formerly known as Rootstock, an Argentinian startup building the first open-source smart contract platform with a 2-way peg to Bitcoin.RSK Labs CEO Diego Gutiérrez Zaldívar on Bitcoin Smart Contracts Sidechain and Crypto Industry Challenges. Even though at this point of time the 2-way peg security of the RSK blockchain is still relying on a group of third parties called ‘Federation’, in the future the developers promise to bring a “trustless” automatic peg. How fast this happens to some degree depends on the overall miners support. The company says its goal is to add value and functionality to the Bitcoin ecosystem by enabling Ethereum-like smart-contracts, near instant payments and higher-scalability, and this past January after almost two years of development its mainnet dubbed Bamboo was finally launched.
  • Creality’s Ender 3 3D Printer is Now Fully Open Source

Their popular Ender 3 was recently voted “Best 3D Printer Under $200” by All3DP (review here). Now, the company is making their most popular 3D printer, the Ender 3, completely open source. This makes it the first Open Source Hardware Association certified 3D printer in China. This means not just a few files have been shared, but all hardware, CAD files, board schematics and firmware files are available. You can find the updated versions on the company’s GitHub page.
  • Charité's researchers integrate open-source platform into the 'Human Brain Project'
    Universitätsmedizin Berlin and the Berlin Institute of Health (BIH) are pleased to announce that 'The Virtual Brain' neuroinformatics platform has joined the EU's Flagship 'Human Brain Project'. With financial support from the EU's Horizon 2020 research and innovation program, Charité's researchers are now integrating their open-source platform into the 'Human Brain Project'. This will provide participating researchers with a research infrastructure that promotes efficiency and reproducibility. The researchers will focus on refining the theoretical underpinnings of the computer models used, developing efficient simulation technology, and working on neuroinformatics solutions that enhance the reproducibility of studies.

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

  • Atari VCS RAM upgraded to 8GB and Atari confirm you can put a normal Linux distribution on it

    While I remain quite sceptical of the Atari VCS, I'm still pretty interested in it as a Linux gaming device. Atari recently did a Q&A blog post detailing some interesting information about it. The post is written by Rob Wyatt, the System Architect for the Atari VCS device. If the name Rob Wyatt doesn't ring a bell—they were the original Xbox system architect.

  • Atari VCS Product Q&A #1

    At this time the developer program is not open yet and it will come online in the coming months. If you have an application in mind you can start today, make sure it runs on Linux at HD resolution using standard runtime libraries, the changes from this to the AtariOS will be minimal and mostly related to application startup and application packaging. In the very near future we will release documentation on the AtariOS which will detail all the runtime components we support as well as libraries for Linux that mimic the AtariOS.

  • Is it worth $129 to relive your NES Duck Hunt glory days?

    But the folks behind the Modern Mallard Kickstarter campaign figured out a way to overcome this problem -- by using a speedy processor to rewrite the game's code in real time, counteracting the lag. The project includes a hardware mod for both the original Duck Hunt game cartridge and Zapper that makes it compatible with LCD, LED and OLED TVs. Note that the campaign doesn't include the game cartridge or Zapper, so you'll have to use your own.

    You can read more about how the mods work at the bottom of the Kickstarter page.

  • Data breaches show we’re only three clicks away from anarchy

    An IT glitch afflicting BP petrol stations for three hours last Sunday evening might not sound like headline news. A ten-hour meltdown of Visa card payment systems in June was a bigger story — as was the notorious TSB computer upgrade cock-up that started on 20 April, which was still afflicting customers a month later and was reported this week to be causing ruptures between TSB and its Spanish parent Sabadell.

    Meanwhile, what do Fortnum & Mason, Dixons Carphone, Costa Coffee and its sister company Premier Inn have in common with various parts of the NHS? The answer is that they have all suffered recent large-scale ‘data breaches’ that may have put private individuals’ information at risk. IT Governance, a blog that monitors international news stories in this sphere, came up with a global figure of 145 million ‘records leaked’ last month alone. Such leaks are daily events everywhere — and a lesson of the TSB story was that cyber fraudsters are waiting to attack wherever private data becomes accessible, whether because of computer breakdown or lax data protection.

Containers or virtual machines: ​Which is more secure? The answer will surprise you

Filed under
Server
Security

Are virtual machines (VM) more secure than containers? You may think you know the answer, but IBM Research has found containers can be as secure, or more secure, than VMs.

James Bottomley, an IBM Research Distinguished Engineer and top Linux kernel developer, writes: "One of the biggest problems with the current debate about Container vs Hypervisor security is that no-one has actually developed a way of measuring security, so the debate is all in qualitative terms (hypervisors 'feel' more secure than containers because of the interface breadth) but no-one actually has done a quantitative comparison." To meet this need, Bottomley created Horizontal Attack Profile (HAP), designed to describe system security in a way that it can be objectively measured. Bottomley has discovered that "a Docker container with a well crafted seccomp profile (which blocks unexpected system calls) provides roughly equivalent security to a hypervisor."

Linux 4.18-rc5

Filed under
Linux

For some reason this week actually felt very busy, but the rc5 numbers
show otherwise. It's all small and calm, and things are progressing
nicely.

I think the "it felt busy" was partly due to me stressing out over a
nasty VM bug that turned out to have a trivial two-liner fix. But
there were also a fair amount of email threads for future stuff, so
that probably also made me feel last week was busier than the actual
rc5 tree shows.

Anyway, of what little happened in rc5 (see appended shortlog for
details), it's just a fairly random collection of smallish fixes all
over. About a third drivers (nothing in particular stands out - rdma,
usb, ata, mmc, sound) with the rest being some tooling (mostly perf),
some arch updates, some filesystem stuff (mostly reiserfs), some arch
fixlets (mips, arm[64], x86) and some misc core kernel (tracing, VM
fixes, timers, yadda yadda).

TxFS Linux File-System Supports ACID Transactions, Simple API

Filed under
Linux

Presented at this past week's 2018 USENIX Annual Technical Conference (ATC18) was TxFS, the Texas Transactional File System for Linux.

Texas Transactional File System (TxFS) has been in the works for a number of years and is a transactional file-system that offers a simple API, wide range of hardware support, high performance while supporting ACID transactions, and relatively low complexity.

TxFS has been worked on by the University of Texas at Austin as well as VMware Research. Papers on TxFS have been published before but their ATC18 paper can be found here (PDF).

One of the professors involved in this work has also tweeted some different remarks including the file-system is down to just five thousand lines of code by utilizing the file-system journal, how they provided isolation for TxFS transactions, and its very simple API of just three system calls.

    In the GCC 8.1 release and mainline code since April, as the previous article outlined, when using "-march=native" as part of the compiler flags with GCC the full capabilities of the CPU haven't been leveraged. This affects Intel Skylake CPUs and newer generations, including yet to be released hardware like Cannonlake and Icelake.

  • ARM Kills Its RISC-V FUD Website After Staff Revolt

    ARM is under fire for the way it attempted to kneecap a fledgling open-source hardware project, and has retreated from its own line of attack after several days. ARM had launched a website, riscv-basics.com, which purported to offer “real” information on the rival ISA. As one might expect, the “information” on display was a bit less neutral than a visitor might hope for. Taking this kind of shot against an open-source hardware project also struck many in the OSS community as being in exceptionally poor taste, given how critical open source software has been to ARM’s overall success and visibility.

    First, a bit of background: RISC-V is an open-source ISA based on RISC principles and is intended to eventually provide flexible CPU cores for a wide variety of use-cases. By using the BSD license, the RISC-V teams hope to allow for a greater range of projects that support both open and proprietary CPU designs. RISC-V CPUs are already available today in a range of roles and capabilities. Despite some modest initial success, RISC-V, today, isn’t even a rounding error in CPU marketshare measurements. It’s certainly no threat to ARM, which enjoys the mother of all vendor lock-ins measured in per-device terms.

A Second Preview to the Next elementary OS 5.0 (July 2018)

Filed under
Reviews

Here's a second short preview (after the March 2018 one) to the next 5.0 version of elementary OS from the development release. We're getting closer to final now as the Beta 1 has been released and the Beta 2 has been started but it's still not recommended to install or use the Betas. This means do not upgrade to Beta 1 or Beta 2 yet, nor install the Beta, but wait until the final version officially released. To sum it up, in 5.0, the user interface is getting more cool with tons of improvement; and the AppCenter is really amazing with payment system for both developers who deserve funds and users who want to contribute. I also mention how active the development progress is below and how we can help. This preview is very brief and cannot represent the final as the final could have more and more amazing additions. Anyway, wait for the final and enjoy reading!

  • Apache Cassandra at 10: Making a community believe in NoSQL
    Ten years ago this month, when Lehman Brothers was still just about in business and the term NoSQL wasn't even widely known, let alone an irritant, Facebook engineers open-sourced a distributed database system named Cassandra. Back then, the idea that huge numbers of companies would need a scalable database was almost laughable – and that grip of traditional relational database systems is reflected in the mythical moniker given to what would become one of the first of many databases designed to run on a cluster of machines. Named after the Greek figure who was cursed to utter the truth but was never believed, Cassandra might seem an odd choice for a system whose raison d'être is believability – but it delivered a nice dig at the stalwarts of the RDBMS world… and their trust in a false Oracle.

Created over two decades ago at Sun Microsystems, Java was introduced as a “write once, run anywhere” programming language, where all the code would be packaged in a JAR file, and run by a Java Virtual Machine on any platform. The requirements for running code anywhere have expanded with the introduction of containerization, however. Few shops are Java-only these days, and many are turning to containerization for true application portability,

  • 10 Best Kodi Addons You Should Install In 2018 | Legal Addons
    Kodi is one of the most popular media player software which enables you to access videos, music, and pictures via the internet or local storage on a host of platforms. Managed by XBMC foundation, Kodi is an open source software. However, its reputation has been soiled by labeling it as a piracy bearer, and that is why many ask “Is Kodi legal?” You can read more about Kodi and whether it is legal or not here.
  • Summer of Code: Plan for the grand finale
    To get that done, I have to polish up my smack-openpgp branch which has grown to a size of 7000 loc. There are still some minor quirks, but Florian recommended to focus on the big picture instead of spending too much time on small details and edge cases. I also have to release pgpainless to maven central and establish some kind of release cycle. It will be a future challenge for me personally to synchronize the releases of smack-openpgp and pgpainless.
  • Collaborative World Shaping: Why Open-Source Tech Matters in a For-Impact Future
    How many lives could be saved if there was a way to vastly cut down inefficiency and through bureaucracy, by problem solving at a global scale? Could technology help us reach more individuals in need more meaningfully, substantially helping people affected by disasters – in less time? The technology is already out there – but not enough people know about it. In 2017, Hurricane Irma—the strongest hurricane ever recorded in the Atlantic Ocean—made landfall; with widespread, “catastrophic” damage, disaster relief organizations were overwhelmed. “A lot of traditional means of crisis response are very top down, and they didn’t really kick in — we saw headlines about how the Red Cross didn’t show up to shelters,” said Greg Bloom, a community organizer and civic hacker who knew he had to step in to assist.
  • The First Open-Source Smart Contract Platform to be Started by Rootstock
    RSK Labs, formerly known as Rootstock, an Argentinian startup building the first open-source smart contract platform with a 2-way peg to Bitcoin.RSK Labs CEO Diego Gutiérrez Zaldívar on Bitcoin Smart Contracts Sidechain and Crypto Industry Challenges. Even though at this point of time the 2-way peg security of the RSK blockchain is still relying on a group of third parties called ‘Federation’, in the future the developers promise to bring a “trustless” automatic peg. How fast this happens to some degree depends on the overall miners support. The company says its goal is to add value and functionality to the Bitcoin ecosystem by enabling Ethereum-like smart-contracts, near instant payments and higher-scalability, and this past January after almost two years of development its mainnet dubbed Bamboo was finally launched.
  • Creality’s Ender 3 3D Printer is Now Fully Open Source
    Creality3D, founded in 2014, is a 3D printer manufacturer based in China, offering more than 20 products. Their popular Ender 3 was recently voted “Best 3D Printer Under $200” by All3DP (review here). Now, the company is making their most popular 3D printer, the Ender 3, completely open source. This makes it the first Open Source Hardware Association certified 3D printer in China. This means not just a few files have been shared, but all hardware, CAD files, board schematics and firmware files are available. You can find the updated versions on the company’s GitHub page.
  • Charité's researchers integrate open-source platform into the 'Human Brain Project'
    Universitätsmedizin Berlin and the Berlin Institute of Health (BIH) are pleased to announce that 'The Virtual Brain' neuroinformatics platform has joined the EU's Flagship 'Human Brain Project'. With financial support from the EU's Horizon 2020 research and innovation program, Charité's researchers are now integrating their open-source platform into the 'Human Brain Project'. This will provide participating researchers with a research infrastructure that promotes efficiency and reproducibility. The researchers will focus on refining the theoretical underpinnings of the computer models used, developing efficient simulation technology, and working on neuroinformatics solutions that enhance the reproducibility of studies.

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
