Stellarium, Celestia 3D - for Astronomy Enthusiasts

Filed under
Software

Stellarium and Celestia 3D are two incredibly good applications for aspiring star gazers. Stellarium renders 3D photo-realistic skies in real-time while Celestia 3D is an awesome 3D astronomy program that allows users to display objects ranging in scale from artificial satellites to entire galaxies in 3D.

Celestia 3D - Explore Universe Using Celestia Space Simulation Application

Celestia is a free 3D astronomy program. Based on the Hipparcos Catalogue, it allows users to display objects ranging in scale from artificial satellites to entire galaxies in three dimensions. Unlike most planetarium software, the user is free to travel about the Universe.

Containers and Kubernetes News

  • Containers lecture
    Whilst trying to introduce containers, the approach I've taken is to work up the history of Web site/server/app hosting from physical hosting and via Virtual Machines. This gives you the context for their popularity, but I find VMs are not the best way to explain container technology. I prefer to go the other way and look at a process on a multi-user system, the problems due to lack of isolation and steadily build up the isolation available with tools like chroot, etc.
  • As Kubernetes surged in popularity in 2017, it created a vibrant ecosystem
    Kubernetes is actually an open source project, originally developed at Google, which is managed by the Cloud Native Computing Foundation (CNCF). Over the last year, we’ve seen some of the biggest names in tech flocking to the CNCF including AWS, Oracle, Microsoft and others, in large part because they want to have some influence over the development of Kubernetes.
  • Ops Checklist for Monitoring Kubernetes at Scale
    By design, the Kubernetes open source container orchestration engine is not self-monitoring, and a bare installation will typically only have a subset of the monitoring tooling that you will need. In a previous post, we covered the five tools for monitoring Kubernetes in production, at scale, as per recommendations from Kenzan.
  • Kubernetes 1.9 brings beta support for Windows apps
    Kubernetes, the cloud container orchestration program, expands even further and has grown more stable.
  • Kubernetes Linux Container Orchestration System Now Supports Windows Too
    Kubernetes, the open-source, production-grade container orchestration system for automating scaling, deployment, and management of containerized apps, has been updated to version 1.9. Coming two and a half months after version 1.8, Kubernetes 1.9 is here with a bunch of new features like the general availability of the Apps Workloads API (Application Programming Interface), which is enabled by default to provide long-running stateful and stateless workloads, as well as initial, beta support for Windows systems.

The Smallest Server Suite Now Ships with Linux 4.9.69 LTS and OpenSSL 1.0.2n

A minor update to the 23.0 stable series, TheSSS 23.2 is here about three weeks after version 23.1 to update a few core components of its built-in LAMP (Linux, Apache, MariaDB, and PHP) server. Therefore, the live system now runs Linux kernel 4.9.69 LTS, Apache 2.4.29, MariaDB 10.2.11, and PHP 7.0.26. PHP 5.6.32 is installed as well to provide users with extra compatibility for older PHP5 scripts, and TheSSS 23.2 also ships with the latest OpenSSL 1.0.2n commercial-grade Secure Sockets Layer (SSL) and Transport Layer Security (TLS) toolkit and Stunnel 5.44 proxy tool.

Linux Foundation: New Silver Members, OpenContrail, and Xen

  • The Linux Foundation Announces 21 New Silver Members
    The Linux Foundation, the nonprofit organization enabling mass innovation through open source, announced the addition of 21 Silver members. Linux Foundation members help support development of the greatest shared technology resources in history, while accelerating their own innovation through open source leadership and participation.
  • Juniper transfers OpenContrail project to the Linux Foundation
    Juniper Networks is handing over the governance of the OpenContrail project to the Linux Foundation. OpenContrail is an open source network virtualization platform aimed at cloud environments and dealing mainly with the control plane - responsible for traffic routing. Juniper will continue developing and selling a commercial, fully supported version of the software, called simply Contrail.
  • The Linux Foundation Simplifies Xen Hypervisor Usage
    Cloud service providers tend to favor various implementations of the open source Xen hypervisor because it’s simply not cost effective for them to pay to license a commercial hypervisor at scale. It’s not clear to what degree enterprise IT organizations will want to follow suit. But The Linux Foundation that oversees development of Xen aims to increase the appeal of Xen by making available a more streamlined version that is simpler to use. George Dunlap, a Xen Project Contributor and a senior engineer at Citrix, says version 4.10 of the Xen Hypervisor Project includes a new user interface in addition to a trusted computing base (TCB) that has been made smaller and, by extension, more secure. The expectation is that a more compact implementation of Xen will not only consume fewer system resources, but also reduce the overall attack surface exposed, says Dunlap. Those attributes should make Xen a more attractive option, for example, in Internet of Things (IoT) projects where licensing a commercial hypervisor is likely to prove cost prohibitive, adds Dunlap.
  • The Xen Project Welcomes Bitdefender to its Advisory Board
    The Xen Project, a project hosted at The Linux Foundation, today announced Bitdefender, a leading global cybersecurity technology company protecting 500 million users worldwide, is a new Advisory Board member. The Xen Project Advisory Board consists of major cloud companies, virtualization providers, enterprises, and silicon vendors, among others, that advise and support the development of Xen Project software for cloud computing, embedded, IoT use-cases, automotive and security applications.
  • Xen Project Member Spotlight: Bitdefender
    The Xen Project is comprised of a diverse set of member companies and contributors that are committed to the growth and success of the Xen Project Hypervisor. The Xen Project Hypervisor is a staple technology for server and cloud vendors, and is gaining traction in the embedded, security and automotive space. This blog series highlights the companies contributing to the changes and growth being made to the Xen Project, and how the Xen Project technology bolsters their business.
