  • Hardened Usercopy Protection Sent In For Linux 4.8

    The usercopy protection was sent in today for pulling into the Linux 4.8 kernel.

    This user-copy protection support isn't about any form of digital rights management but rather about safeguarding objects being copied to/from user-space. I covered this work in more detail a few days ago in Hardened Usercopy Appears Ready To Be Merged For Linux 4.8.

  • SMR Drive Support In Linux 4.8 To Be Further Improved

    With the Linux 4.7 kernel came initial work on SMR drives, a.k.a. Shingled Magnetic Recording. With Linux 4.8 the SMR drive support continues to be improved.

    Shingled Magnetic Recording is a magnetic storage tech used by HDDs with high storage density.

Canonical Joins The Document Foundation's LibreOffice Project Advisory Board

LibO
Ubuntu

Today, July 26, 2016, Canonical and The Document Foundation (TDF) announced that the company behind the popular Ubuntu operating system had joined the LibreOffice project Advisory Board.

If you're using the Ubuntu Linux OS on your personal computer, you are aware of the fact that the award-winning LibreOffice office suite is installed by default. Canonical chose to use LibreOffice as the default office suite for its widely-used GNU/Linux operating system since the first release of the open-source software in early 2011.

Now that Canonical announced the availability of Snaps as universal binary packages for Ubuntu and other supported GNU/Linux distributions, many application developers decided to offer their software in the Snap package format, and it looks like The Document Foundation is among the first to adopt the latest Snappy technologies for LibreOffice.

Linux Filesystems Explained — EXT2/3/4, XFS, Btrfs, ZFS

Filed under
Linux

The first time I installed Ubuntu on my computer, when I was sixteen, I was astonished by the number of filesystems that were available for the system installation. There were so many that I was left overwhelmed and confused. I was worried that if I picked the wrong one my system might run too slow or that it might be more problematic than another. I wanted to know which was the best.

Since then, things have changed quite a bit. Many Linux distributions offer a ‘standard’ filesystem that an installation will default to unless otherwise specified. I think this was a very good move because it assists newcomers in making a decision and being comfortable with it. But, for those that are still unsure of some of the contemporary offerings, we’ll be going through them today.

  • Last gasp: Microsoft updates Get Windows 10 nagster, KB 3035583, yet again

    With nine days to go, Microsoft really, really wants you to claim your free upgrade to Windows 10. Come to think of it, Microsoft has really, really wanted you to upgrade your Windows 7 or 8.1 PC to Windows 10 for more than a year, and backed it with the GWX subsystem -- first installed by KB 3035583 in March 2015, 15 months ago.

  • GNOME Keysign - Report #2 GSoC 2016

    More than a week ago I blogged about the new GUI made with GtkBuilder and Glade [1]. Now, I will talk about what has changed since then with the GUI and also the new functionality that has been added to it.

    I will start with the new "transition" page which I've added for the key download phase. Before going more in depth, I have to say that the app knows at each moment in what state it is, which really helps in adding more functionality.

  • Introducing: openSUSE heroes

    During the last weeks, the openSUSE board and others expressed their concern about the current state of some openSUSE infrastructure: especially the reaction times to change something in the setup were mentioned multiple times. Looks like we lost some administrators and/or contact points at SUSE who helped out in the past to eliminate problems or work together with the community.

    As result, there was a meeting held during the openSUSE Conference 2016, including some SUSE employees and openSUSE community members to discuss the current situation and search for some possible solutions. The discussion was very fruitful and we’d like to share some of the results here to inform everyone and actively ask for help. If you want to join us, the openSUSE heroes, do not hesitate to contact us and join an incredible team!

Server Administration

  • Open Source Docker Monitoring & Logging

    Docker is growing by leaps and bounds, and along with it, its ecosystem. Being light, the predominant container deployment involves running just a single app or service inside each container. Most software products and services are made up of at least several such apps/services. We all want all our apps/services to be highly available and fault tolerant. Thus, Docker containers in an organization quickly start popping up like mushrooms after the rain. They multiply faster than rabbits.While, in the beginning, we play with them like cute little pets, as their numbers quickly grow we realize we are dealing with a herd of cattle, implying we’ve become cowboys. Managing a herd with your two hands, a horse, and a lasso will only get you so far. You won’t be able to ride after each and every calf that wonders in the wrong direction. To get back to containers from this zoological analogy—operating so many moving pieces at scale is impossible without orchestration—this is why we’ve seen the rise of Docker Swarm, Kubernetes, Mesos, CoreOS, RancherOS, and so on.

  • DevOps: A Pillar of Modern IT Infrastructure

    A massive transformation is underway in the way we manage IT infrastructure. More companies are looking for improved agility and flexibility. They are moving from traditional server stacks to cloudy infrastructure to support a new array of applications and services that must be delivered at breakneck pace in order to remain competitive.

  • The one big change in IT

    Yet Bob does not believe the devops hammer should be used on anything that looks remotely like a nail. Accounting systems, supply chain management systems, warehouse management systems, and so on do not benefit from the constant modification enabled by devops. Those are bound by precise, interlocking processes along with granular permissions and regulations. Here, continuous change invites disaster of the type that ITIL-huggers and OCM (organizational change management) proponents fear most.

  • Collabora contributions to Linux Kernel 4.7

    Linux Kernel 4.7 was released this week with a total of 36 contributions from five Collabora engineers. It includes the first contributions from Helen as Collaboran and the first ever contributions on the kernel from Robert Foss. Here are some of the highlights of the work Collabora have done on Linux Kernel 4.7.

    Enric added support for the Analogix anx78xx DRM Bridge and fixed two SD Card related issues on OMAP igep00x0: fix remove/insert detection and enable support to read the write-protect pin.

    Gustavo de-staged the sync_file framework (Android Sync framework) that will be used to add explicit fencing support to the graphics pipeline and started a work to clean up usage of legacy vblank helpers.

  • The new Linux Kernel 4.7 is now officially released

    For users who are running some form of Linux, this should come as welcome news--the final version of the Linux Kernel 4.7 is now finally released. Linux founder Linus Torvalds said of the announcement, “Despite it being two weeks since rc7, the final patch wasn’t all that big, and much of it is trivial one- and few-liners. There’s a couple of network drivers that got a bit more loving.”

  • OpenVZ 7.0 Becomes A Complete Linux Distribution, Based On VzLinux

    OpenVZ, a long-standing Linux virtualization technology and similar to LXC and Solaris Containers, is out with their major 7.0 release.

    OpenVZ 7.0 has focused on merging the OpenVZ and Virtuozzo code-bases along with replacing their own hypervisor with that of Linux's KVM. Under OpenVZ 7.0, it has become a complete Linux distribution based upon VzLinux.

  • OpenVZ 7.0 released

    I’m pleased to announce the release of OpenVZ 7.0. The new release focuses on merging OpenVZ and Virtuozzo source codebase, replacing our own hypervisor with KVM.

  • FreeIPA Lightweight CA internals

    In the preceding post, I explained the use cases for the FreeIPA lightweight sub-CAs feature, how to manage CAs and use them to issue certificates, and current limitations. In this post I detail some of the internals of how the feature works, including how signing keys are distributed to replicas, and how sub-CA certificate renewal works. I conclude with a brief retrospective on delivering the feature.

  • Lightweight Sub-CAs in FreeIPA 4.4

    Last year FreeIPA 4.2 brought us some great new certificate management features, including custom certificate profiles and user certificates. The upcoming FreeIPA 4.4 release builds upon this groundwork and introduces lightweight sub-CAs, a feature that lets admins to mint new CAs under the main FreeIPA CA and allows certificates for different purposes to be issued in different certificate domains. In this post I will review the use cases and demonstrate the process of creating, managing and issuing certificates from sub-CAs. (A follow-up post will detail some of the mechanisms that operate behind the scenes to make the feature work.)

  • RcppArmadillo 0.7.200.2.0

    The second Armadillo release of the 7.* series came out a few weeks ago: version 7.200.2. And RcppArmadillo version 0.7.200.2.0 is now on CRAN and uploaded to Debian. This followed the usual thorough reverse-dependecy checking of by now over 240 packages using it.

    For once, I let it simmer a little preparing only a package update via the GitHub repo without preparing a CRAN upload to lower the update frequency a little. Seeing that Conrad has started to release 7.300.0 tarballs, the time for a (final) 7.200.2 upload was now right.

    Just like the previous, it now requires a recent enough compiler. As g++ is so common, we explicitly test for version 4.6 or newer. So if you happen to be on an older RHEL or CentOS release, you may need to get yourself a more modern compiler. R on Windows is now at 4.9.3 which is decent (yet stable) choice; the 4.8 series of g++ will also do. For reference, the current LTS of Ubuntu is at 5.4.0, and we have g++ 6.1 available in Debian testing.

  • Debian LGBTIQA+

    I have a long overdue blog entry about what happened in recent times. People that follow my tweets did catch some things. Most noteworthy there was the Trans*Inter*Congress in Munich at the start of May. It was an absolute blast. I met so many nice and great people, talked and experienced so many great things there that I'm still having a great motivational push from it every time I think back. It was also the time when I realized that I in fact do have body dysphoria even though I thought I'm fine with my body in general: Being tall is a huge issue for me. Realizing that I have a huge issue (yes, pun intended) with my length was quite relieving, even though it doesn't make it go away. It's something that makes passing and transitioning for me harder. I'm well aware that there are tall women, and that there are dedicated shops for lengthy women, but that's not the only thing that I have trouble with. What bothers me most is what people read into tall people: that they are always someone they can lean on for comfort, that tall people are always considered to be self confident and standing up for themselves (another pun, I know ... my bad).

  • Debian on Jetson TK1

    I became interested in running Debian on NVIDIA's Tegra platform recently. NVIDIA is doing a great job getting support for Tegra upstream (u-boot, kernel, X.org and other projects). As part of ensuring good Debian support for Tegra, I wanted to install Debian on a Jetson TK1, a development board from NVIDIA based on the Tegra K1 chip (Tegra 124), a 32-bit ARM chip.

  • Keeping the FCC and Open Source Happy

    The FCC is worried. You and they spend all this time and energy getting your radio certified, and then some bozo hacks in, changes how the radio works, and puts you out of spec.

    And so, back in early 2015, the FCC issued some guidelines or questions regarding WiFi devices – particularly home routers – in an effort to ensure that your radio isn’t hackable.

    The result has been that some router makers have simply locked down the platform so that it’s no longer possible to do after-market modifications, and this has caused an outcry by after-market modifiers. The reason why it’s an issue is that these open-source developers have used the platform for adding apps or other software that, presumably, have nothing to do with the radio.

    In an attempt to find the magic middle way, the prpl organization, headed by Imagination Technologies (IMG) and featuring the MIPS architecture, recently put out a proof of concept that they say gives both assurance to the FCC and freedom to open-source developers.

  • Wire open-sources messaging client, woos developers

    Communications startup Wire has open-sourced the full codebase for its Wire app, so it's easier for developers to build their own encrypted messaging clients.

    Wire open-sourced the rest of the client base that wasn't initially publicly available, including components related to the user interface, the web and native clients, and some internal developer tools. The company always planned to open-source the codebase, but didn't start out that way initially "because we were still working on other features," Alan Duric, co-founder and CTO of Wire, wrote in a Medium post.

  • Open data platform on Emilia-Romagna reconstruction

    After the two earthquakes that caused multiple casualties and widespread damage in the Italian region of Emilia-Romagna in 2012, multiple programmes were launched to reconstruct the affected areas. To make these efforts more transparent, a team from the Gran Sasso Science Institute last week presented an Open Data platform that will provide all information on who is responsible, which company is doing what, and how the money is being spent.

    The 'Open Data Ricostruzione' initiative was presented last week at the Italian Festival of Participation. The platform will bring together all the numbers, figures and information on the reconstruction, and allow visitors to visualise, filter, track and map the available data. All information will be made available as open data, in the original database format as well as JSON.

  • AArch64 desktop hardware?

    Soon there will be four years since I started working on AArch64 architecture. Lot of software things changed during that time. Lot in a hardware too. But machines availability still sucks badly.

    In 2012 all we had was software model. It was slow, terribly slow. Common joke was AArch64 developers standing in a queue for 10GHz x86-64 cpus. So I was generating working binaries by using cross compilation. But many distributions only do native builds. In models. Imagine Qt4 building for 3-4 days…

    In 2013 I got access to first server hardware. With first silicon version of CPU. Highly unstable, we could use just one core etc. GCC was crashing like hell but we managed to get stable build results from it. Qt4 was building in few hours now.

  • RISC-V on an FPGA, pt. 1

    Last year I had open source instruction set RISC-V running Linux emulated in qemu. However to really get into the architecture, and restore my very rusty FPGA skills, wouldn’t it be fun to have RISC-V working in real hardware.

    The world of RISC-V is pretty confusing for outsiders. There are a bunch of affiliated companies, researchers who are producing actual silicon (nothing you can buy of course), and the affiliated(?) lowRISC project which is trying to produce a fully open source chip. I’m starting with lowRISC since they have three iterations of a design that you can install on reasonably cheap FPGA development boards like the one above. (I’m going to try to install “Untether 0.2” which is the second iteration of their FPGA design.)
