  • Linux 5.2/5.3 Kernel Performance On The AMD Ryzen 9 3900X

    With yesterday's Windows 10 vs. Ubuntu 18.04 LTS Linux benchmarks for the AMD Ryzen 9 3900X, some suggested that the Linux performance could have been better if using a Linux 5.x kernel. Well, here are some benchmarks comparing the performance of Ubuntu 18.04.2 LTS with its Linux 4.18 kernel compared to Linux 5.2 stable as well as the brand new Linux 5.3 development kernel.

    On the same Ryzen 9 3900X system, these three kernel releases (Ubuntu 18.04's stock 4.18 kernel, Linux 5.2 stable, Linux 5.3 Git) were compared across a variety of workloads.

  • QuickHash GUI is an open source hashing tool for Windows, Linux and macOS

    QuickHash GUI is an open source hashing tool which is available for Windows, Linux and macOS. If you're a security conscious person or want to verify file integrity, e.g. for backups, you must be aware of hashing.

  • curl goez parallel

    The first curl release ever saw the light of day on March 20, 1998 and already then, curl could transfer any amount of URLs given on the command line. It would iterate over the entire list and transfer them one by one.

    Not even 22 years later, we introduce the ability for the curl command line tool to do parallel transfers! Instead of doing all the provided URLs one by one and only start the next one once the previous has been completed, curl can now be told to do all of them, or at least many of them, at the same time!

    This has the potential to drastically decrease the amount of time it takes to complete an operation that involves multiple URLs.

  • KDE Connect mDNS: Nuremberg Megaspring Part 2

    Sprints are a great time to talk in real-time to other project developers. One of the things we talked about at the KDE Connect part of the “Nuremberg Megasprint” was the problem that our current discovery protocol often doesn’t work, since many networks block the UDP broadcast we currently use. Additionally, we often get feature requests for more privacy-conscious modes of KDE Connect operation. Fixing either of these problems would require a new Link Provider (as we call it), and maybe we can fix both at once.


    Solving the first problem is easy. We want the user’s device name so we can display it in the list of available devices to pair with. So, instead of sending that information in the identity all the time, have some “discovery mode” switch which otherwise withholds the device name until a connection to an already-trusted device is established.

    This leaves the second problem, which quite a bit more tricky. One answer is to have trusted user-selected trusted wifi networks, so KDE Connect doesn’t broadcast on a random wifi that the user connects to. But what if I connect to, say, my university network where I want to use KDE Connect but I don’t want to tell everyone that I’m here?

    We don’t have a final answer to this question, but we discussed a few possible solutions. We would like some way of verifying ourselves to the other device which conceals our identity behind some shared secret, so the other device can trust that we are who we say we are, but other devices can’t fingerprint us. It is a tricky problem but not yet one to solve. Step 1 is to get the new mDNS backend working, step 2 is to add advanced features to it!

  • Sysadmins need to know – how DO you pronounce “sudo”?

    Most of the year, sysadmins have to worry about things that are bugging YOU.

    They have to worry about the things that YOU need fixed right now, that YOU have decided are more important than everyone else’s problems put together, and that YOU shouldn’t have to put up with if only the world were fair, etc.

    No matter that the problem YOU are having is caused by a problem that YOU created.

    If your sysadmins were any good they’d have set things up so that YOU couldn’t have got it wrong in the first place.

    No matter that they did, indeed, set it up just like that but YOU complained about feeling stifled…

    …and YOU turned off the safety feature all by yourself, with the help of your neighbour’s friend’s cousin’s 9-year-old child, who’s just happens to be a computer whizzkid.

  • Icinga 2.11 Release Candidate

    For months we have been working on one of the biggest and most important releases since the creation of Icinga 2. Icinga 2 version 2.11 includes improvements for performance, stability and scalability. After many changes of lines of code, additions and deletions we believe we’re finally there. But we want to have you on board, so we decided to go with a Release Candidate first. Today we’re happy to announce the general availability of this release!

    As you may know, Icinga’s core and network stack is written from scratch in C++, specifically the REST API and network event handling. They caused problems, and the attempts the past releases couldn’t reliably make them go away. We’ve therefore decided to do something unusual and resource intensive: Rewrite the whole network stack by using modern programming techniques and throw away the old implementation. This is a huge step forward and some may say, this would be Icinga 3.

    Coming late to the party, fixes for reload handling and unwanted notifications also turned into a long-awaited feature: Run Icinga 2 in foreground and let the new umbrella process handle restarts and reloads. Additionally to the issues we’re aiming to fix, this comes in very handy for (Docker) containers as well!

  • Tech convergence set to drive automotive open source acceptance

    The convergence of technologies in autonomous vehicles is set to spur more acceptance of open source use across the automotive industry and drive car companies to adopt better freedom-to-operate processes, according to car manufacturers and their suppliers.

    Senior IP counsel at Volvo Cars, Lotus, u-Blox and elsewhere say car companies have traditionally stipulated in supplier agreements that components should be free from open source technologies, for fear that any third-party rights attached to those technologies could taint their products – among other things.

    They explain that it is a common and inaccurate assumption that open source software is always free to use. In reality, these technologies are governed by a spectrum of licences: from copyleft ones that require inventors to put modifications back into the open source pool, to permissive licences such as Apache 2.0 that allow modifications to be commercialised.


    With the loosening of restrictions surrounding open source use to take advantage of the open source space, however, comes the need for new processes to mitigate the risk of unknowingly incorporating technologies that have been ‘borrowed’ or have restrictive licences attached.

    Not only do car companies need to check for third-party rights, they also need to ensure that any of the code used does not have a ‘back door’ built into it that would allow someone to hack into a product.

    Gisler at Volvo Cars points out that car companies should assess risk anyway to ensure that components do not taint end products, given the increasing popularity of open source technology, even if they are not yet relaxing their supplier contracts.

  • Clear Linux Moving Ahead With Their Third-Party Packaging Support

    In recent months we've heard of Intel engineers working on better supporting third-party packages on Clear Linux that would be akin to Arch's AUR, Ubuntu's PPA, or Fedora's Copr systems for allowing unofficial/third-party packages to be more easily made available particularly in cases of closed-source software. It looks like that internally that system is now in beta as they work towards having more software available on Clear Linux.

    In response to a mailing list question over whether Clear Linux has any ambitions for a commercial edition and to use the likes of Intel's commercial software offerings on Clear Linux, Intel's Arjan van de Ven commented on those prospects.

  • Top 20 Best Machine Learning Datasets for Practicing Applied ML

    We all know that to build up a machine learning project, we need a dataset. Generally, these machine learning datasets are used for research purpose. A dataset is the collection of homogeneous data. Dataset is used to train and evaluate the machine learning model. It plays a vital role to build up an efficient and reliable system. If your dataset is noise-free and standard, then your system will give better accuracy. However, at present, we are enriched with numerous datasets. It can be business-related data, or it can be medical data and many more. However, the actual problem is to find out the relevant ones according to the system requirements.

    I have prostate cancer.

I’ve attempted to summarize the points I’ve made during the talk here, and happy to have a conversation or add more rules based on your observations in this space over the last ten years. I strongly believe there are some lasting concepts and axioms that are true in infrastructure IT, and documenting some of them is important to guide decisions that go into the next generation thinking as we evolve in this space.

  • Empowering voters to combat election manipulation

    For the last year, Mozilla has been looking for ways to empower voters in light of the shifts in election dynamics caused by the internet and online advertising. This work included our participation in the EU’s Code of Practice on Disinformation to push for change in the industry which led to the launch of the Firefox EU Elections toolkit that provided people information on the voting process, how tracking and opaque online advertising influence their voting behavior and how they can easily protect themselves.

    We also had hoped to lend our technical expertise to create an analysis dashboard that would help researchers and journalists monitor the elections. The dashboard would gather data on the political ads running on various platforms and provide a concise “behind the scenes” look at how these ads were shared and targeted.

    But to achieve this we needed the platforms to follow through on their own commitment to make the data available through their Ad Archive APIs.

  • Uber releases Ludwig 0.2 with audio and speech improvements, plus and BERT integration

    Roughly five months following the debut of Ludwig, Uber’s open source and no-code deep learning toolkit, the ride-hailing company today detailed improvements with the latest version: Ludwig 0.2. Among them are new tools and over 50 bug fixes, plus integration, the addition of Google’s BERT natural language model, and support for new feature types including audio, speech, geospatial, time, and date.

    “The simplicity and the declarative nature of Ludwig’s model definition files allows machine learning beginners to be productive very quickly, while its flexibility and extensibility enables even machine learning experts to use it for new tasks with custom models,” wrote Uber engineers Piero Molino, Yaroslav Dudin, and Sai Sumanth Miryala. “Members of the broader open source community contributed many of new features to enhance Ludwig’s capabilities.”

  • EFF Extensions Recommended by Firefox

    Earlier this month, Mozilla announced the release of Firefox 68, which includes a curated "list of recommended extensions that have been thoroughly reviewed for security, usability and usefulness." We are pleased to announce that both of our popular browser extensions, HTTPS Everywhere and Privacy Badger, have been included as part of the program. Now, when you navigate to the built-in Firefox add-ons page (URL: about:addons), you'll see a new tab: "Recommendations," which includes HTTPS Everywhere and Privacy Badger among a list of other recommended extensions. In addition, they will be highlighted in Add-ons for Firefox and in add-on searches.

    What does this mean for users who already have our extensions installed? If you initially installed them from or the recommendation list, it means that there will be a slight delay after we update the extensions while Mozilla reviews the new versions for security, utility, and user experience. If you installed the self-hosted extensions directly from without going through Mozilla, you'll get the updates right away after a routine automated check. Either way, you can rest assured that EFF has audited every piece of software we release for security and performance problems.

Miller works at Agoric which is leading the way on modern application of object capabilities, which is convenient, since exploration of how to apply object capabilities to federated social networks is a major topic of interest on the fediverse.

    But just leaving it at that would be leaving out too much. We can trace Mark's relevance back to the world's first large online social network, which it turns out was a graphical multiplayer game which ran on the Commodore 64 (!!!) called Lucasfilm's Habitat. (You can see the entertaining trailer for this game... keep in mind, this was released in 1986!) Mark then went on to write the Agoric papers in 1988 (more complete archive here) which laid out the vision for a massive society and economy of computing agents. (And yes, that's where the Agoric company got its name from.)

  • SUSE Welcomes Cimitra for it’s “Just Enough Administration” Solution

    The Cimitra server is distributed as a Docker container that can easily drop right into a Docker implementation on SLES12 or SLES15. Cimitra ships as a free solution limited to 3 users and 3 agents. No license is needed. And the free version never expires. Select the “Try” option at Cimitra’s website to get the free version. 
    The Cimitra web client is designed to present actions that are simply connections to pre-generated scripts and commands. Cimitra end-users can perform actions without having to be granted OS administrator logins or sudo access. One of the problems that IT support organizations are experiencing is that many rudimentary management functions require system administration rights thus requiring the cost of having sysadmin-trained IT staff available to perform simple duties, or putting the organization at risk by either generating too many privileged accounts or having to manage dozens of different roles.
    For example, a script or command to restart an Apache webserver (rcapache2 restart) is presented to Mike from the Help Desk. Mike doesn’t need any rights on the Linux server to Trun the scripts that have been provided to him, thus granting Mike the ability to perform just the actions given to him. A catalog of such scripts would free highly-trained system administration staff to perform more serious work and Level 1 support could perform the tasks in the catalog without needed administrative/root authority and console access.

    That's right! We're hosting the first ever ActivityPub Conf. It's immediately following Rebooting Web of Trust in Prague.

    There's no admission fee to attend. (Relatedly, the conference is kind of being done on the cheap, because it is being funded by organizers who are themselves barely funded.) The venue, however, is quite cool: it's at the DOX Centre for Contemporary Art, which is itself exploring the ways the digital world is affecting our lives.

    If you plan on attending (and maybe also speaking), you should get in your application soon (see the flier for details). We've never done one of these, and we have no idea what the response will be like, so this is going to be a smaller gathering (about 40 people). In some ways, it will be somewhere between a conference and a gathering of people-who-are-interested-in-activitypub.

    As said in the flier, by attending, you are agreeing to the code of conduct, so be sure to read that.

  • Valve releases a new update to the Steam Client, nice Linux fixes made it in again

    Valve have released a new stable version of the Steam Client today to add new features, improve existing features and catch some pesky bugs flying around.

    There's some better "client logic" to choose and connect to download servers, which should hopefully give better download speeds, better connection login in initializing the friends list, screenshots in SteamVR Home should be sorted, a fix for certain web page elements continuing to render in the Steam client when it is minimized or closed to the system tray, some "improved reliability of registry saving on Linux and macOS" and the SteamVR dashboard should no longer obscure transition overlays when launching a game.

  • Intel Is Still Working On Upstreaming SGX Enclave Support To Linux - Now At 21 Revisions

    Intel Software Guard Extensions "SGX" have been around since Skylake for allowing hardware-protected (via encryption) memory regions known as "enclaves" that prevent processes outside of the enclave from accessing these memory regions. While supported CPUs have been out for years, the Intel SGX support has yet to make it into the mainline kernel and this week marks the twenty-first revision to these patches. 

    The twenty-eight patches implementing the Intel SGX foundations support for the Linux kernel and Intel Memory Encryption Engine support were revised with various fixes. Even if the review of this twenty-first revision to these patches go spectacular, due to the timing this SGX support won't land until at least the Linux 5.4 kernel with being too late for Linux 5.3.

Security Leftovers

  • Security updates for Wednesday

    Security updates have been issued by CentOS (firefox and kernel), Debian (thunderbird), Fedora (curl), openSUSE (curl and python-Werkzeug), Oracle (kernel and thunderbird), Red Hat (rh-nginx114-nginx), SUSE (curl, ibus, MozillaFirefox, firefox-glib2, firefox-gtk3, openldap2, openssl, openssl1, python-urllib3, and util-linux and shadow), and Ubuntu (linux, linux-aws, linux-azure, linux-lts-trusty, linux-lts-xenial, linux-oracle, linux-raspi2, linux-snapdragon, and wpa).

  • SGX and security modules

    Software Guard Extensions (SGX) is a set of security-related instructions for Intel processors; it allows the creation of private regions of memory, called "enclaves". The aim of this feature is to work like an inverted sandbox: instead of protecting the system from malicious code, it protects an application from a compromised kernel hypervisor, or other application. Linux support for SGX has existed out-of-tree for years, and the effort of upstreaming it has reached an impressive version 22 of the patch set. During the upstreaming discussion, the kernel developers discovered that the proposed SGX API did not play nicely with existing security mechanisms, including Linux security modules (LSMs).

LWN Articles About Linux (Kernel): Linux Plumbers Conference, Staging, Linux Conference North America, Stable Statistics

  • Topics from the Open Printing microconference

    On day two of the 2019 Linux Plumbers Conference, two of the principals behind the Open Printing project led the very first Open Printing microconference. Project leader Till Kamppeter and program manager Aveek Basu described the current state of printing on Linux and some of the plans for the future, including supporting scanning for multi-function devices. The picture they painted was rosy, at least for printing, which may not quite match the experience of many Linux users. As with many projects, though, Open Printing is starved for contributors—something that was reflected in the sparse attendance at the microconference. Basu began by pointing out that some attendees had likely printed their boarding passes from Linux, which highlights the importance of printing for Linux. People use it for bank documents, transport tickets, and more. He has been at Lexmark for 11 years, working on printing for Linux, macOS, and other Unix-based systems. Kamppeter said that he has been the Open Printing leader since 2001. The idea of the project is to do everything possible to make printing "just work" with Linux and other operating systems; the goal is "plug and print".

  • What happens to kernel staging-tree code

    The staging tree was added to the kernel in 2008 for the 2.6.28 development cycle as a way to ease the process of getting substandard device drivers into shape and merged into the mainline. It has been followed by controversy for just about as long. The recent disagreements over the EROFS and exFAT filesystems have reignited many of the arguments over whether the staging tree is beneficial to the kernel community or not. LWN cannot answer that question, but we can look into what has transpired in the staging tree in its first eleven years to see if there are any conclusions to be drawn there. The core idea behind the staging tree is that it is open to code that does not live up to the normal standards for inclusion into the kernel. Once a driver is added there, it is available to anybody who is brave enough to try to make use of it, but the real purpose is to allow developers to improve the code to the point that it is ready to go into the kernel proper. It serves as an easy place for new developers to try out simple changes and, when it works well, it helps the kernel to gain hardware support that might otherwise languish out-of-tree indefinitely.

  • The USB debugging arsenal

    At the 2019 Embedded Linux Conference North America, which was held in San Diego in August, Krzysztof Opasiak gave a presentation on demystifying the ways to monitor—and even change—USB traffic on a Linux system. He started with the basics of the USB protocol and worked up into software and hardware tools to observe, modify, and fuzz the messages that get sent. Those tools are part of the arsenal that is available to those interested in looking deeply into USB. Opasiak works in Poland for what he called a "small Korean company" (Samsung). He noted that it is not that easy to sniff USB traffic and that the ways to do so are not well known. But "there are no dragons"; nothing bad will happen if you do so. In some ways, USB is like the internet and some of the same tools can be used for both.

  • 5.3 Kernel development cycle statistics

    It's that time of the development cycle again: work on the 5.3 kernel is winding down with an expected final release date of September 15. Read on for LWN's traditional look at where the code in 5.3 came from in this relatively busy development cycle. As of this writing, 14,435 non-merge changesets have been pulled into the mainline repository for 5.3; these changes were contributed by 1,846 developers

Kmdr – Display CLI Commands Explanation In Terminal

A while ago, we wrote about ExplainShell, a web-based tool to learn what each part of a Linux command does. It divides the complex and lengthy Linux commands into multiple parts and gives explanation for each part. Using this tool, a Linux newbie can learn about various command line parameters and options without having to refer man pages. However, It will only help you to learn Linux commands. But what if you want to learn other CLI commands, for example Python? You won’t find explanation of Python commands in ExplainShell. No worries! Today, I stumbled upon a similar tool named Kmdr that provides CLI commands explanation for hundreds of programs. It helps you to easily learn CLI commands without leaving the terminal and without having to go through lengthy man pages. Not just Linux commands, Kmdr provides explanation for a lot of CLI commands including ansible, conda, docker, git, go, kubectl, mongo, mysql, npm, ruby gems, vagrant and hundreds of other programs such as those built into bash.
