  • Important, but obscure, sysadmin tool osquery gets a foundation of its own

    But users think osquery's founder, Facebook, has been neglecting osquery. Going forward, Facebook has turned osquery over to The Linux Foundation. There, engineers and developers from Dactiv, Facebook, Google, Kolide, Trail of Bits, Uptycs, and other companies invested in osquery, will support it under the new foundation: The osquery Foundation.

    That's a good thing because while you may not have heard of osquery, many major companies, such as Airbnb, Dropbox, Netflix, Palantir, Etsy, and Uber, rely on it. This project needed a new lease on life.

    How does it work? Osquery exposes server operating system as a high-performance relational database. This allows you to write SQL-based queries to explore operating system data and low level system information. In osquery, SQL tables represent abstract concepts such as running processes, loaded kernel modules, open network connections, browser plugins, hardware events or file hashes.These are kept in a SQLite DBMS.

  • Running Ubuntu on the One Mix Yoga 3 mini laptop (video)

    The One Mix Yoga 3 is a small laptop that features an 8.4 inch touchscreen display and a convertible tablet-style design. It ships with Windows 10, but one of the first things I tried doing with the tablet was to boot a GNU/Linux distribution.

    I posted some notes about what happened when I took Ubuntu 19.04 for a spin on the One Mix 3 Yoga in my first-look article, but plenty of folks who watched my first look video on YouTube asked for a video… so I made one of those too.

  • Cockroach and the Source Available Future [Ed: The proprietary software giants-funded pundits like PedMonk on the openwashing agenda ("Source Available"... like "Shared Source" or "Inner Source"). What a crock.]

    Earlier this month, the database company Cockroach Labs relicensed its flagship database product. This is notable for two reasons. Most obviously, the company is following in the footsteps of several of its commercial open source database peers such as Confluent, Elastic, MongoDB, Redis Labs and TimescaleDB that have felt compelled to apply licenses that are neither open source nor, in most cases, traditionally proprietary.

    But the relicensing of CockroachDB is also interesting because this isn’t the first time the company has applied such a license.

    In January of 2017, Cockroach Labs announced the introduction of what it called the CockroachDB Community License (CCL). To the company’s credit, in the post announcing this new license, it took pains to make it clear that the CCL, while making source code available, was not in fact an open source license because it restricted redistribution. The CCL essentially enforced a two tier, open core-type business model, in which a base version of the database was made available under a permissive open source license (Apache) while certain enterprise features were made available under the CCL, which essentially requires users of these premium, enterprise-oriented features to pay for them.

    With its recent relicensing, the original dual core model has been deprecated. Moving forward, CockroachDB will be made available under two non-open source licenses – which, as an aside to Cockroach, presumably means that section 1B of the CCL probably needs to be updated. The CCL will continue to govern the premium featureset, but the original open source codebase will moving forward be governed by the Business Source License (BSL). Originally released by MariaDB, the BSL is a source available license; a license that makes source code for a project available, but places more restrictions upon its usage than is permitted by open source licenses.

  • 18 letters from readers that we loved

    In the news article titled ‘What's in a Name?’ in the November 2002 issue, Linux was addressed as “Linus Torvalds’ operating system” and you mentioned that Richard Stallman wants it to be ‘renamed’ as GNU/Linux. The OS we know today as Linux was born out of the GNU project, conceived by Stallman in 1984. It is very strange how Torvalds, who only contributed in creating the kernel, is today considered to be the creator of the entire Linux system. The whole ideology behind the Linux OS remains concealed from the users—that of software created free, by and for the masses. In that context, I think there is complete justification in calling the system GNU/Linux to give credit where it is due.

  • Finally, An Open Source Multimeter

    This build is based on the STM32F103 microcontroller, uses an old Nokia phone screen, and unlike so many other multimeters, this thing is small. It’s very small. More than small enough to fit in your pocket and forget about it, unlike nearly every other multimeter available. There’s one thing about multimeters, and it’s that the best multimeter is the one that you have in your hands when you need it, and this one certainly fits the bill.

  • The OS/2 Operating System Didn't Die… It Went Underground

    One problem with building things using state-of-the-art techniques is that sometimes those that look like they will be “the next big thing” turn out to be dead ends. Next thing you know, that hot new part or piece of software is hard to get or unmaintained. This is especially true if you are building something with a long life span. A case in point is the New York City subway system. Back in the 1990s the transit authority decided to adopt IBM’s new OS/2 operating system. Why not? It was robust and we used to always say “no one ever got fired for buying IBM.”

    There was one problem. OS/2 was completely eclipsed by other operating systems, notably Windows and — mostly — has sunk from the public view. [Andrew Egan’s] post covers just how the conversion to a card-based system pushed OS/2 underground all over the Big Apple, and it is an interesting read.

    The choice of OS/2 might seem odd today. However, you have to remember the operating system landscape back then. Unix wasn’t very commercial, for the most part, and the commercial versions like Xenix and SCO were often encumbered with odd and changing licensing arrangements. MSDOS was hardly suitable for any sort of reliable system, with a patchwork of hacks to get more memory, and multitasking including early versions of Windows which were little more than shells over MSDOS.

    Auke is a long-time Intel Linux developer and also one of the prominent contributors to Clear Linux going back to its early days. Among the highlights from Wednesday's "ask me anything" included: 

    - When asked about Fedora's flicker-free boot process, Auke pointed out that it's made possible in part through work spearheaded at Intel around the frame-buffer/fastboot code worked on by their graphics team. While it's great the shared work happening, from the Clear Linux perspective they are more focused on achieving lightning fast boot times over a slick boot process. But they may look into it in some aspect moving forward, but their priority is just to have a quick booting system.

    Enter, the science project.  Given an all-flash environment on SATA SSDS with a fast storage pool on Intel Optane for the metadata, would it be possible to provide a reasonable storage environment for HPC clusters?

  • The Best Free Photoshop Alternatives

    GIMP, or GNU Image Manipulation Program, is more than just a photo editor. It also has sophisticated image manipulation tools, which will appeal to pros as well as regular uers.

Plus it has more advanced tools, like layers, content rescaling, and animation, plus the ability to add blur, noise, and distortion, among other effects.

    In fact GIMP offers most of the features that Photoshop has, even if it is missing things like other color modes besides RGB and the capability for non-destructive editing. Even better, GIMP’s interface is very customizable, and its features are expandable. Since it is open source, GIMP community members can create plugins, and they often do, sharing them to the rest of the community for free.

  • Linux 5.3 Could Finally See FSGSBASE - Performance Improvements Back To Ivybridge

    The FSGSBASE instruction set has been present on Intel processors going back to Ivy Bridge processors and while there have been Linux kernel patches for this feature going on for years, it looks like with the Linux 5.3 kernel cycle is this support for merging. Making us eager for this support is the prospect of better performance, especially for context switching workloads that already have been suffering as a result of recent CPU mitigations. 

    The FSGSBASE instructions allow for reading/writing FS/GS BASE from any privilege. But the short story is there should be performance benefits from FSGSBASE in context switching thanks to skipping an MSR write for GSBASE. User-space programs like Java are also expected to benefit in being able to avoid system calls for editing the FS/GS BASE.

    As you can see, the security audit can be tailored based on any security controls you have/need. NIST provides the 800-53A (“A” is for audit or assessment) and provides different file formats to use. This is a great place to start creating your own audit document.

    To sum it up, embracing self-audits and the benefit they provide will reduce risk and save time. The longer a security control remains in a failed state, the more time threats have to exploit a vulnerability. Protect yourself and add security by prioritizing audits.

  • Georges Basile Stavracas Neto: Calendar management dialog, archiving task lists, Every Detail Matters on Settings (Sprint 2)

    This was a long-time request, and something that I myself was missing when using To Do. Since it fits well with the product vision of the app, there was nothing preventing it from being implemented.

    Selecting this feature to be implemented during the week was a great choice – the task was self contained, had a clear end, and was just difficult just enough to be challenging but not more than that.

    However, I found a few issues with the implementation, and want to use the next round to polish the feature. Using the entire week to polish the feature might be too much, but it will give me some time to really make it great.

  • Robert Helmer: Vectiv and the Browser Monoculture

    So, so tired of the "hot take" that having a single browser engine implementation is good, and there is no value to having multiple implementations of a standard. I have a little story to tell about this.

    In the late 90s, I worked for a company called Vectiv. There isn't much info on the web (the name has been used by other companies in the meantime), this old press release is one of the few I can find.

    Vectiv was a web-based service for commercial real estate departments doing site selection. This was pretty revolutionary at the time, as the state-of-the-art for most of these was to buy a bunch of paper maps and put them up on the walls, using push-pins to keep track of current and possible store locations.

    The story of Vectiv is interesting on its own, but the relevant bit to this story is that it was written for and tested exclusively in IE 5.5 for Windows, as was the style at the time. The once-dominant Netscape browser had plummeted to negligible market share, and was struggling to rewrite Netscape 6 to be based on the open-source Mozilla Suite.

    To start with our list, let’s talk about one of the more popular educational operating systems, EduBuntu. Does the name sound familiar, well this OS is a variation of the popular Windows alternative, Ubuntu. It’s built on the reliable Linux system and is supported by a strong Linux community.

    The software was built from kids aged 6 to 18. The system was built in collaboration with Educators around the world to ensure that the system serves its purpose as a great education source for kids. The system is built for teachers in mind as well as you don’t need a lot of technical knowledge to set it up in your computer lab or PC.

    Edubuntu comes packed with a number of useful education programs such as the KDE Edutainment application suite. What we love about this OS is that there is no need to reformat your PC if it’s already running Ubuntu. You can simply turn the Ubuntu software into Edubuntu through a series of steps.

  • GSoC 2019 – Week 2 with the Titler Tool

    In the last week, I gained progress with the QML rendering library (see the code here)

    It is doing what it is supposed to do – it renders an input QML file to output frames of a specified format and renders it as quick as possible (with QQuickRenderControl). If you want to test it out – there is CLI access to it through an executable (which is one of the things I’ve been working in the last week) for the library in the test directory here (make sure you read the READMEs along the way!)

    So let’s try to understand what really happens at the core of the library i.e. the rendering part.

    To render QML, the obvious approach is to take ‘screenshots’ of each frame using a grab() method which would grab all the pixels at each instant of time and then render it – not only is this darned slow and expensive, it is also not possible to render at a custom frame rate that way.

Review: HexagonOS 1.0

On the whole, Hexagon worked well for me. Hardware support was solid, performance was above average, the included applications worked well, and the settings were easy to adjust. I had very few complaints - just two really: my keyboard layout had to be adjusted and Hexagon did not automatically work well with VirtualBox. However, both of these issues were easily addressed. With that being said, Hexagon appears to bring relatively little, technologically, to the experience over its parent. While running this distribution I sometimes forgot that I was not simply running Xubuntu with a dock installed. The custom utilities Hexagon provides (the software centre and the backup tool) both function, but are quite limited in what they can do for the user and this makes me disinclined to use them over other solutions like Deja Dup and GNOME Software. It's probably too soon to judge what HexagonOS will become. Right now it's just at its 1.0 release, and appears to be a first attempt to take Xubuntu and customize it with a few changes. Hopefully future versions will try more new things, polish the custom applications and distinguish the distribution from its parent. Read more
