  • Upcoming Gallery Block improvements

    An exciting update to the Gallery Block gives you more ways to show off images in your posts and pages. While this change won’t be available for most folks until WordPress 5.9’s launch in December, we wanted to share some of what’s to come to get you excited about the future.

    Below are updates, news and event information from some of our Affiliate Members.

  • Rugged DAQ board expands with PCIe/104 OneBank

    Diamond’s “Saturn” PCIe/104 SBC for data acquisition runs Ubuntu or Win 10 on Apollo Lake with up to 8GB soldered RAM, 2x GbE, 2x HDMI, 4x USB, 3x COM, analog and digital I/Os, and M.2, mini-PCIe, and OneBank expansion.

    Diamond Systems has announced a rugged, PCIe/104 form factor SBC aimed at digital acquisition tasks. Like Diamond’s Zeta boardset, the Saturn SBC runs Linux or Windows on Intel’s Apollo Lake. Like its AMD G-Series or i.MX6 based Quantum SBC, it adopts the legacy PCIe/104 form factor, and more specifically uses the stackable PCIe/104 OneBank expansion interface.

  • Obsolete IdenTrust root certificate will lead to loss of trust in Let’s Encrypt on older devices

    On September 30, at 17:01 Moscow time , the lifetime of the IdenTrust root certificate (DST Root CA X3) expires , which was used to cross-sign the root certificate of the Let’s Encrypt certification authority ( ISRG Root X1 ), controlled by the community and providing certificates for free to everyone. Cross-signing has ensured the trust of Let’s Encrypt certificates on a wide range of devices, operating systems and browsers while integrating Let’s Encrypt’s own root certificate into root certificate stores.

    It was originally planned that after the DST Root CA X3 is out of date, the Let’s Encrypt project will switch to generating signatures using only its root certificate, but such a step would lead to a loss of compatibility with a large number of old systems that did not add the Let’s Encrypt root certificate to their repositories. In particular, approximately 30% of Android devices in use do not have data on the Let’s Encrypt root certificate, support for which appeared only starting from the Android 7.1.1 platform, released at the end of 2016.

  • Red Hat automation glossary

    Automation is an increasingly strategic necessity as organizations of all sizes strive to deliver value faster while solving IT and business workflow challenges.

    Here we offer a quick glossary of automation terms, including links where you can dive in deeper to learn more.

  • Configuring Red Hat Ansible Automation Platform with GitOps

    Red Hat Ansible Automation Platform comes in handy when organizations start to implement Infrastructure as Code and GitOps concepts. But what about the automation of the platform itself?

    Before we get started it’s good to clarify some product component naming. Ansible Tower is being renamed to Automation Controller in the upcoming Ansible Automation Platform 2 release. While things are being changed, you can see both words "tower" and "controller" used interchangeably in various contexts including roles and collections. For more information on Ansible Automation Platform please refer to this Knowledge Base Article.

    Almost all of the assets in Ansible Tower can be backed with SCM-based repositories. Yet, there's a little gap in how this content (Job Templates, Projects, Inventories, etc.) is initially created and subsequently managed. This becomes especially visible on large deployments. For example, a Project in Ansible Tower can be backed by a Git repository with the automation code.

  • MiTubo 0.3 brings basic RSS support | Mardy

    I just pushed MiTubo 0.3 to the Ubuntu Touch app store, added a link to the AppImage package in the Releases page and later during the night the Launchpad builders should import it and build it for Ubuntu 18.04 and 20.04.

    This release adds basic support for RSS feeds. One just needs to type the address of an RSS (or Atom) feed in the search bar and the "Search" button will transform itself into a "Subscribe" one. Unfortunately no discovery mechanism is implemented yet, so one cannot just enter the address of a webpage and expect MiTubo to find the feed URL(s); I plan to bring that in a future release, but for the time being you'll have to enter the exact address of the RSS feed.

  • Plasma 25th Anniversary Edition Beta Testing Day

Infrastructure living the ideals of software freedom

Can organisations with limited resources be digitally sovereign and still provide modern services? It is not trivial, but the FSFE proves it's possible. Take a deep dive with us into our infrastructure to learn how we run all the different services within the FSFE and cope with numerous challenges. A story non only for techies. Charity, non-profit organisations run into limits every day: personnel, budget, time, and the pressing question how to use donations most efficiently. When it comes to technical infrastructure, many organisations unfortunately decide to outsource and use proprietary, non-free services. By this, they give up software freedom and thereby digital sovereignty and independence. Since its founding more than 20 years ago, the FSFE has been pursuing the opposite way. Right from the start, we have relied on Free Software although it sometimes meant not being able to use and offer trendy services. Also, given the limited resources, we constantly have to choose between useful features and maintainability. Read more

Ubuntu Frame - A picture is worth a thousand snaps

The development of graphical applications intended for use on IoT devices isn’t trivial. The complexity goes beyond the usual challenges that exist in the classic desktop and server domains. One, the IoT world is much less mature. Two, developers need to take into consideration various edge cases that do not apply to hands-on devices like laptops, for instance. Kiosks, industrial displays and digital signage devices require additional focus and rigor. Ubuntu Frame is a solution designed to simplify and streamline the build and development of products that need graphical output. On a technical level, it is a fullscreen shell, based on Wayland, intended for interactive usage applications. On a product level, Ubuntu Frame bundles communication protocols, input protocols and security policies into a single kit, which can then be used in IoT devices. You can test it today. Read more

LoRa HAT starts at $31

SB Components is crowdfunding a $31-and-up “LoRa HAT for Raspberry Pi” with a 5-Km range at 868MHz or 433MHz. There is also a $47 “LoRa Expansion for Pico” board with a pre-soldered RPi Pico. Raspberry Pi milliner SB Components, which is behind such RPi HATs as the PiFinger fingerprint sensor HAT, has won Kickstarter funding for a simple, low-cost LoRa communications HAT. The LoRa HAT for Raspberry Pi is still available in a super early bird special for 23 UK Pounds ($31), as well as an identical 30-Pound ($40) package discounted from the eventual 40-Pound retail price.

Preparing for PipeWire

In the coming year, PipeWire will replace PulseAudio resulting in better audio on Linux. If you can't wait, here's what you need to know to get started with PipeWire. Unless you use a version of Fedora released in 2021, you may not have heard of PipeWire. However, by this time next year, PipeWire will likely be installed on your computer. Already, many distributions are starting to carry PipeWire (marked as experimental) in their repositories. Still unfinished with its installation varied depending on distribution, PipeWire is about to replace PulseAudio as Linux’s main audio server. If you are unwilling to wait until PipeWire becomes a standard part of a Linux installation, here is what you should know. PipeWire was created by Wim Taymans of Red Hat in 2015. Based on an earlier project called PulseVideo, PipeWire was originally intended as a server for capture and playback of audio and video. The video side of the project is still in development, but the audio side is mature enough that in the spring of 2021 Fedora 34 become the first Linux distribution to install it by default. In Fedora 34, PipeWire is used to manage PulseAudio, JACK, ALSA, and GStreamer-based applications. Read more
