    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.

  • 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    It was originally planned that after the DST Root CA X3 is out of date, the Let’s Encrypt project will switch to generating signatures using only its root certificate, but such a step would lead to a loss of compatibility with a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

  • 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.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
