What is Ubuntu? Ubuntu (pronounced oo-BOON-too) is a free, open source operating system (OS) based on Debian Linux. It was first released in 2004 when Mark Shuttleworth and a small team of Debian developers founded Canonical and then launched the Ubuntu project. Canonical released its first official version of the OS — Ubuntu 4.10 — […]
What is a semiconductor fab? A semiconductor fab — short for fabrication — is a manufacturing plant in which raw silicon wafers are turned into integrated circuits (ICs). A fab lab features a clean room where ICs are etched onto wafers. The completed chips are sent to a back-end assembly and test facility before they […]
What is Dell EMC VxRail? Dell EMC VxRail is a hyper-converged appliance. Like VSPEX Blue — the Dell EMC product that it replaced — and other hyper-converged infrastructure (HCI) systems, VxRail includes compute, storage, networking and virtualization resources in a single device. Specifically, Dell EMC VxRail packages the VMware vSphere vSAN hypervisor and VMware vCenter […]
Security-Enhanced Linux is a powerful security system that is enabled, by default, on most Linux distributions based on RHEL. Admins and users often disable SELinux, even though that’s not the best option. SELinux can make it a challenge to get newly installed or custom applications to run because it blocks them from having access to […]
The edge computing market is growing rapidly, driven by the need for real-time analytics, new edge technologies and rising costs in the public cloud. But what is edge? There are many definitions of the edge, from remote offices and manufacturing sites — sometimes called near edge — to communications towers, IoT devices and autonomous vehicles […]
Data centers — and the fleets of hot, always-on and power-hungry servers within them — produce a lot of heat. Admins are constantly working to ensure equipment doesn’t overheat or break down due to nonoptimal heat and humidity levels, but some data centers are reusing their heat, instead of dispelling it. Heat from data centers […]
Criticism continued this week over Red Hat’s decision to alter the way it makes Red Hat Enterprise Linux (RHEL) available to developers and users, who believe the changes could make it more expensive. Late last month, Red Hat doubled down on its commitment to CentOS Stream as a way to improve collaboration with the open […]
In the development world, flexibility and agility are key. This is part of the reason why open source — building open apps without any limits — is also key. This is the claim that SUSE makes at SUSECON 2023, their annual conference, with their messaging about how to address organizational challenges. SUSE is a global […]
What is multiprocessing? Multiprocessing is the utilization of two or more central processing units (CPUs) in a single computer system. Its definition can vary depending on the context, but generally it refers to a system’s ability to support multiple CPUs and its capacity to distribute work among them. Multicore processors today are easily capable of […]
