  • Comparison of Memory Usages of Ubuntu 19.04 and Flavors in 2019

    Continuing my previous Mem. Comparison 2018, here's my 2019 comparison with all editions of Ubuntu 19.04 "Disco Dingo". The operating system editions I use here are the eight: Ubuntu Desktop, Kubuntu, Lubuntu, Xubuntu, Ubuntu MATE, Ubuntu Studio, Ubuntu Kylin, and Ubuntu Budgie. I installed every one of them on my laptop and (immediately at first login) took screenshot of the System Monitor (or Task Manager) without doing anything else. I present here the screenshots along with each variant's list of processes at the time I took them. And, you can download the ODS file I used to create the chart below. Finally, I hope this comparison helps all of you and next time somebody can make better comparisons.

  • Ubuntu 18.10 (Cosmic Cuttlefish) End of Life reached on July 18 2019
    This is a follow-up to the End of Life warning sent earlier this month
    to confirm that as of today (July 18, 2019), Ubuntu 18.10 is no longer
    supported.  No more package updates will be accepted to 18.10, and
    it will be archived to old-releases.ubuntu.com in the coming weeks.
    
    
    
    
    The original End of Life warning follows, with upgrade instructions:
    
    
    
    
    Ubuntu announced its 18.10 (Cosmic Cuttlefish) release almost 9 months
    ago, on October 18, 2018.  As a non-LTS release, 18.10 has a 9-month
    support cycle and, as such, the support period is now nearing its
    end and Ubuntu 18.10 will reach end of life on Thursday, July 18th.
    
    
    
    
    At that time, Ubuntu Security Notices will no longer include
    information or updated packages for Ubuntu 18.10.
    
    
    
    
    The supported upgrade path from Ubuntu 18.10 is via Ubuntu 19.04.
    Instructions and caveats for the upgrade may be found at:
    
    
    
    
    https://help.ubuntu.com/community/DiscoUpgrades
    
    
    
    
    Ubuntu 19.04 continues to be actively supported with security updates
    and select high-impact bug fixes.  Announcements of security updates
    for Ubuntu releases are sent to the ubuntu-security-announce mailing
    list, information about which may be found at:
    
    
    
    
    https://lists.ubuntu.com/mailman/listinfo/ubuntu-security-announce
    
    
    
    
    Since its launch in October 2004 Ubuntu has become one of the most
    highly regarded Linux distributions with millions of users in homes,
    schools, businesses and governments around the world. Ubuntu is Open
    Source software, costs nothing to download, and users are free to
    customise or alter their software in order to meet their needs.

  • CMake leverages the Snapcraft Summit with Travis CI to build snaps

    CMake is an open-source, cross-platform family of tools designed to build, test and package software. It is used to control the software compilation process and generate native makefiles and workspaces that can be used in any compiler environment. 

    While some users of CMake want to stay up to date with the latest release, others want to be able to stay with a known version and choose when to move forward to newer releases, picking up just the minor bug fixes for the feature release they are tracking. Users may also occasionally need to roll back to an earlier feature release, such as when a bug or a change introduced in a newer CMake version exposes problems within their project.

    Craig Scott, one of the co-maintainers of CMake, sees snaps as an excellent solution to these needs. Snaps’ ability to support separate tracks for each feature release in addition to giving users the choice of following official releases, release candidates or bleeding edge builds are an ideal fit. When he received an invitation to the 2019 Snapcraft Summit, he was keen to work directly with those at the pointy end of developing and supporting the snap system. 

  • Ubuntu's Zsys Client/Daemon For ZFS On Linux Continues Maturing For Eoan

    Looking ahead to Ubuntu 19.10 as the cycle before Ubuntu 20.04 LTS, one of the areas exciting us with the work being done by Canonical is (besides the great upstream GNOME performance work) easily comes down to the work they are pursuing on better ZFS On Linux integration with even aiming to offer ZFS as a file-system option from their desktop installer. A big role in their ZoL play is also the new "Zsys" component they have been developing.

  • John Goerzen: Tips for Upgrading to, And Securing, Debian Buster

    Wow.  Once again, a Debian release impresses me — a guy that’s been using Debian for more than 20 years.  For the first time I can ever recall, buster not only supported suspend-to-disk out of the box on my laptop, but it did so on an encrypted volume atop LVM.  Very impressive!

    For those upgrading from previous releases, I have a few tips to enhance the experience with buster.

  • Clear Linux Could Soon Be Faster Within Containers On AVX2 Systems

    While Clear Linux as part of its standard bare metal installations has long defaulted to having an AVX2-optimized GNU C Library installed by default, it turns out that it wasn't part of the default os-core bundle as used by containers. That though is changing and should yield even better out-of-the-box performance when running Clear Linux within containers.

    Intel's William Douglas sent out the proposal for adding the AVX2 version of the Glibc libraries into the os-core bundle in order to get picked up by containers and other bare/lightweight Clear configurations.

  • OpenSUSE Enables LTO By Default For Tumbleweed - Smaller & Faster Binaries

    The past few months openSUSE developers have been working on enabling LTO by default for its packages while now finally with the newest release of the rolling-release openSUSE Tumbleweed this goal has been accomplished. 

    As of today, the latest openSUSE Tumbleweed release is using Link-Time Optimizations (LTO) by default. For end-users this should mean faster -- and smaller -- binaries thanks to the additional optimizations performed at link-time. Link-time optimizations allow for different optimizations to be performed at link-time for the different bits comprising a single module/binary for the entire program. Sadly not many Linux distributions are yet LTO'ing their entire package set besides the aggressive ones like Clear Linux. 

  • Investigating why my 7-year old Windows 10 laptop became unbearably slow

    The laptop had also begun to run into blue screens of death (BSoD) whenever I used the built-in camera and when I opened Spotify or Netflix in a web browser. The slowdown and crashes were actually related, but I didn’t realize this at first. The camera-induced BSoD error message blamed the camera vendor’s driver without any further details. This sounds believable enough for a 7-year old laptop so I didn’t think any more of it.

Google, Money and Censorship in Free Software communities

Filed under
Google
Web
Debian

Alexander Wirt (formorer) has tried to justify censoring the mailing list in various ways. Wirt is also one of Debian's GSoC administrators and mentors, it appears he has a massive conflict of interest when censoring posts about Google.

Wirt has also made public threats to censor other discussions, for example, the DebConf Israel debate. The challenges of holding a successful event in that particular region require a far more mature approach.

Why are these donations and conflicts of interest hidden from the free software community who rely on, interact with contribute to Debian in so many ways? Why doesn't Debian provide a level playing field, why does money from Google get this veil of secrecy?

[...]

Google also operates a mailing list for mentors in Google Summer of Code. It looks a lot like any other free software community mailing list except for one thing: censorship.

Look through the "Received" headers of messages on the mailing list and you can find examples of messages that were delayed for some hours waiting for approval. It is not clear how many messages were silently censored, never appearing at all.

Recent attempts to discuss the issue on Google's own mailing list produced an unsurprising result: more censorship.

Univention Corporate Server 4.4-1/Point Release UCS 4.4-1: performance improvements, app recommendations and UDM REST API Beta

Filed under
Debian

There are significant performance improvements for managing the contents of the directory service via UDM, especially for application scenarios with complex structures. There have also been further minor improvements in DNS management, where the search for IP addresses is now enabled in further modules, as well as in the use of standard containers of domain controller objects.

A brand new feature is the REST API for UDM, which considerably facilitates the integration of UDM with other applications. This REST API has been released as beta version for the time being. After further tests and improvements we plan to release a stable version in autumn.

Review: Debian 10 "Buster"

Filed under
Debian

Debian is one of the world's oldest Linux distributions and, in terms of the number of developers involved, also one of the largest. Around 1,300 contributors worked on Debian 10, which was released on July 6th.

Debian 10 offers package upgrades across the entire operating system, but the main changes for this release include enabling AppArmor by default and running GNOME Shell on Wayland. (GNOME running on X.Org is available as an alternative desktop session.) The project's release announcement also mentions nftables can be used to manage the operating system's firewall and Secure Boot is enabled for some architectures. This version of Debian will receive a total of five years of support, thanks to the project's long-term support team.

The new version of Debian, codenamed "Buster", runs on over half a dozen CPU architectures and is available in net-install, full DVD install, and seven live desktop editions. This gives users many install options and avenues for trying the distribution. Though not mentioned in the distribution's release announcement Debian's media does not include non-free firmware which is often required to connect with wireless networks. People who need wireless networking have the option of downloading unofficial live images with non-free firmware.

Some more experimental users may be interested in knowing that Debian not only has a Linux flavour, but also offers builds with alternative kernels. The Debian GNU/Hurd team published new install media alongside the main Linux editions.

I ended up downloading the DVD install media, which is 3.6GB in size. I also downloaded the official live GNOME edition which is 2.3GB. My observations in this review come from installing and running Debian based on the install DVD media, unless otherwise specified.

Septor Linux For Surfing Internet Anonymously

Filed under
Debian

Septor Linux is based on Debian, and uses Tor technologies to make users anonymous online. Septor 2019.4 has Linux kernel 4.19 and customized version of KDE Plasma 5.14.3.

If you do not know what Tor is, you can read this guide to know Tor in detail. But in short, Tor network transfers users requests through different other Tor clients used by people in other parts of the World which makes users completely anonymous. Due to this nature of transferring requests through many clients, it is also called the onion network.

Debian Linux 10 'Buster' Places Stability Ahead of Excitement

Reviews
Debian

If you are relatively new to using Linux, Debian's design decisions will not pose obstacles to using it. If you insist on speedier application updates, you might spend excessive time grabbing newer versions from .deb repositories that are outside Buster's reach.

Get Debian 10 Buster ISO downloads here.

You will have plenty of time to resolve those issues. The developers have a long slog to the release of Debian 11, aka "Bullseye."

I can only hope that the next Debian upgrade comes a lot closer to hitting an improved bull's-eye that is less boring.

My Debian 10 (buster) Report

Filed under
Debian

In the early hours of Sunday morning (my time), Debian 10 (buster) was released. It’s amazing to be a part of an organisation where so many people work so hard to pull together and make something like this happen. Creating and supporting a stable release can be tedious work, but it’s essential for any kind of large-scale or long-term deployments. I feel honored to have had a small part in this release

My primary focus area for this release was to get Debian live images in a good shape. It’s not perfect yet, but I think we made some headway. The out of box experiences for the desktop environments on live images are better, and we added a new graphical installer that makes Debian easier to install for the average laptop/desktop user. For the bullseye release I intend to ramp up quality efforts and have a bunch of ideas to make that happen, but more on that another time.

FreeBSD 12 & DragonFlyBSD 5.6 Running Well On The AMD Ryzen 7 3700X + MSI X570 GODLIKE

For those wondering how well FreeBSD and DragonFlyBSD are handling AMD's new Ryzen 3000 series desktop processors, here are some benchmarks on a Ryzen 7 3700X with MSI MEG X570 GODLIKE where both of these popular BSD operating systems were working out-of-the-box. For some fun mid-week benchmarking, here are those results of FreeBSD 12.0 and DragonFlyBSD 5.6.2 up against openSUSE Tumbleweed and Ubuntu 19.04. Back in July I looked at FreeBSD 12 on the Ryzen 9 3900X but at that time at least DragonFlyBSD had troubles booting on that system. When trying out the Ryzen 7 3700X + MSI GODLIKE X570 motherboard on the latest BIOS, everything "just worked" without any compatibility issues for either of these BSDs. Read more

How to break out of a hypervisor: Abuse Qemu-KVM on-Linux pre-5.3 – or VMware with an AMD driver

A pair of newly disclosed security flaws could allow malicious virtual machine guests to break out of their hypervisor's walled gardens and execute malicious code on the host box. Both CVE-2019-14835 and CVE-2019-5049 are not particularly easy to exploit as they require specific types of hardware or events to occur. However, if successful, either could allow a miscreant to run malware on the host from a VM instance. CVE-2019-14835 was discovered and reported by Peter Pi, a member of the Tencent Blade Team. It is found in the Linux kernel versions 2.6.34 up to version 5.3, where it is patched. Read more
