  • Hands-On Lab: Oracle Linux Disk Encryption Using Network Based Key Services

    Many Linux environments require data to be encrypted at rest but that can add administrative overhead to the boot process. Oracle Linux has supported disk encryption since version 5 but a feature was added in 7 update 4 to allow the automatic unlocking of devices based on external network services. Network Bound Disk Encryption (NBDE) uses a network based key service to validate a system is on a trusted network and unlock encrypted disks upon boot. By combining NBDE and a keyboard entered passphrase the system will unlock a disk automatically during boot but allow administrators to use a passphrase during maintenance operations.

    A new hands-on lab Oracle Linux Disk Encryption Using Network Based Key Services is now available for anyone to learn the concepts of Linux disk encryption. The lab begins with the creation of a encrypted block device dependent on a passphrase and continues to an example of network based keys to unlock the device. Oracle Linux 8 is used but the same tools are available on Oracle Linux 7. The base components involved include dm-crypt which allows arbitrary block devices to be encrypted, Linux Unified Key Setup (LUKS) a disk encryption standard and cryptsetup which is used to configure our disks. We continue to include Tang, a network service that provides cryptographic services over HTTP and Clevis, an encryption framework. Clevis can use keys provided by Tang as a passphrase to unlock LUKS volumes.

  • Mir 1.7.1 Released With X11 Support Promoted Out Of "Experimental" Phase

    Most significant with Mir 1.7.1 is the X11 support being improved to the point that it's no longer considered experimental for running traditional X11 software atop Wayland. Passing --enable-x11 now can be used for enabling the X11 support rather than the prior "x11-display-experimental" option. Mir 1.7.1 saw a lot of work to the XWayland and X11 window manage code, including a new display FD option.

  • Liquid Prep, a solution that helps farmers optimize water usage during droughts, is now open source

    When a prolonged absence of water in a region leads to drought conditions, the entire ecosystem suffers. Among those hardest hit are farmers, and the impact on their land can have ripple effects on the larger population. These larger problems can range from health issues or food security, while also creating conditions that increase the risk of wildfires and dust storms.

    Created by five technologists from the IBM offices in Ottawa, Ontario, Canada, Liquid Prep is a solution designed for low-literate farmers in developing countries whose success hinges on access to advanced agricultural advice. By leveraging the use of an intuitive mobile Android app, local soil sensors, and weather forecast information as well as an advanced agricultural decision platform hosted on IBM Cloud, farmers are better informed on how to use limited water supplies and increase their chances of growing healthy crops for their small plots of land.

The dual 4K display NP-FP5 and more feature-rich, triple 4K display BP-FP5 SBCs support the same V1000 and R1000 models. The lower-end NP-FP5 also supports the low-power, 8-10W TDP R1305G, which was announced today by AMD along with a 6W R1102G.

  • Mirantis co-founder launches FreedomFi to bring private LTE networks to enterprises

    Boris Renski, the co-founder of Mirantis, one of the earliest and best-funded players in the OpenStack space a few years ago (which then mostly pivoted to Kubernetes and DevOps), has left his role as CMO to focus his efforts on a new startup: FreedomFi. The new company brings together open-source hardware and software to give enterprises a new way to leverage the newly opened 3.5 GHz band for private LTE and — later — 5G IoT deployments.

  • Luis Villa: Surviving 2020 on Twitter

    At some point in the past few years, I accepted that I’m going to have a baseline level of anger about the state of the world, and that I have to focus on what I can change and let go of what I can’t. (Twitter anger is the latter.) So what can I change? Where is my anger productive?

    I’ve found that doing things offline—for me, mostly giving money—really helps. In particular, giving to causes that seek systemic (usually, that means political/government) change like 350.org and local activist groups, and giving a lot, and regularly. This, frankly, makes it a lot easier for me to ignore anger online — each new tweet is not likely to make me be more angry, or give more, because I’m already basically giving what I can. Being confident about that really reduced my FOMO when I started filtering aggressively.

    I hear from non-parents/non-startup-founders that physical-world activism (door-knocking, phone banking, local gov meeting-attending, etc.) can be great in this way too but sadly I can’t confirm Sad

    (I also want to acknowledge that, in the current state of the world, ‘letting go’ gets harder the less privilege you have. I have no great response to that, except to say that I empathize and am trying to fight for you where and how I can.)

  • Why Source Code Scanning Tools are Essential to Open Source Compliance [Ed: This promotes proprietary software of Microsoft 'proxies', along with FUD, to make proprietary software sales]

    There are many scanning tools and vendors to choose from. For example, Black Duck, WhiteSource, and FOSSA are well-known vendors that offer scanning tools on a subscription basis. FOSSology is an open source scanning tool maintained by the Linux Foundation, but it doesn’t come with a pre-populated library of open source code or software repository, which you would need to build on your own.

  • Google and Microsoft are scaring consumers over Edge extensions, and for what?

    Simply trying to install a Chrome extension via the Chrome Web Store actually requires navigating through several warnings, from both Google and Microsoft, about where to go to install an extension. The confusion and frustration this no doubt creates with users reflects poorly on both sides.

4 new open source licenses

As the steward of the Open Source Defintion, the Open Source Initiative has been designating licenses as "open source" for over 20 years. These licenses are the foundation of the open source software ecosystem, ensuring that everyone can use, improve, and share software. When a license is approved, it is because the OSI believes that the license fosters collaboration and sharing for the benefit of everyone who participates in the ecosystem. The world has changed over the past 20 years, with software now used in new and even unimaginable ways. The OSI has seen that the familiar open source licenses are not always well-suited for these new situations. But license stewards have stepped up, submitting several new licenses for more expansive uses. The OSI was challenged to evaluate whether these new concepts in licensing would continue to advance sharing and collaboration and merit being referred to as "open source" licenses, ultimately approving some new special purpose licenses.

Can Linux Run Video Games?

Linux is a widely used and popular open source operating system that was first released back in 1991. It differs from operating systems like Windows and macOS in that it is open source and it is highly customizable through its use of “distributions”. Distributions or “distros” are basically different versions of Linux that can be installed along with the Linux core software so that users can customize their system to fit their specific need. Some of the more popular Linux distributions are Ubuntu, Debian and Fedora. For many years Linux had the reputation of being a terrible gaming platform and it was believed that users wouldn’t be able to engage in this popular form of entertainment. The main reason for this is that commercially successful games just weren’t being developed for Linux. A few well known video game titles like Doom, Quake and SimCity made it to Linux but for the most part they were overlooked through the 1990’s. However, things have changed a lot since then and there is an every expanding library of popular video games you can play on Linux. [...] There are plenty of Windows games you can run on Linux and no reason why you can’t play as well as you do when using Windows. If you are having trouble leveling up or winning the best loot, consider trying AskBoosters for help with your game. Aside from native Linux games and Windows games there are a huge amount of browser based games that work on any system including Linux. Read more
