Linux's WireGuard VPN is here and ready to protect you

Linus Torvalds has released the newest version of the Linux 5.6. It includes many new and neat features like USB4 support, a fix for the 32-bit Epoch problem, multi-path TCP, and numerous driver patches. The biggest news of all s that Linux now has the popular open-source Virtual Private Network (VPN) WireGuard baked in.

WireGuard is a radical new approach to VPNs. With its minimal codebase -- about 4,000 lines of code -- it's much easier to debug and secure than its rivals such as OpenVPN with its over 100,000 lines.

Torvalds himself loves WireGuard for its simplicity. Long before he incorporated WireGuard into Linux, Tovalids said  "Can I just once again state my love for it and hope it gets merged soon? Maybe the code isn't perfect, but I've skimmed it, and compared to the horrors that are OpenVPN and IPSec, it's a work of art."

The Protocols That Help Things to Communicate Over the Internet

The Internet of Things is a system of connected, interrelated objects. These objects transmit data to servers for processing and, in turn, receive messages from the servers. These messages are sent and received using different protocols. This article discusses some of the protocols related to the IoT.

The Internet of Things (IoT) is beginning to pervade more and more aspects of our lives. Everyone, everywhere is using the Internet of Things. Using the Internet, connected things are used to collect information, convey/send information back, or do both. IoT is an architecture that is a combination of available technologies. It helps to make our daily lives more pleasant and convenient.

FOSS Tools that Help to Create and Deliver E-learning Content

E-learning is today making educational resources highly accessible for a large number of learners. However, various important steps have to be followed to build and deliver e-learning content. This article highlights a number of tools that can be used in the e-learning content creation and delivery process.

Learning is an integral part of our life. With the knowledge based ecosystem that we live in, it has become mandatory to continue the learning process even after we have completed a formal school or university based education. E-learning has emerged as a primary learning channel for many of us due to various factors such as variable time availability, learner-centric pacing, the opportunity to learn from the best teachers and institutions in the field, etc. Hence, e-learning content creation and management should be carried out with the utmost care, considering the large number of learners impacted by the tutorial material created. Well-built e-learning material should be very effective in reaching a large number of learners and achieving the intended learning objectives.

8 reasons to consider hyperconverged infrastructure for your data center

Demand for on-premises data center equipment is shrinking as organizations move workloads to the cloud. But on-prem is far from dead, and one segment that’s thriving is hyperconverged infrastructure (HCI).

HCI is a form of scale-out, software-integrated infrastructure that applies a modular approach to compute, network and storage capacity. Rather than silos with specialized hardware, HCI leverages distributed, horizontal blocks of commodity hardware and delivers a single-pane dashboard for reporting and management. Form factors vary: Enterprises can choose to deploy hardware-agnostic hyperconvergence software from vendors such as Nutanix and VMware, or an integrated HCI appliance from vendors such as HP Enterprise, Dell, Cisco, and Lenovo.
