What to know about open source security

Like any area of tech, open source needs its own security measures to thrive without a hitch. A major benefit that organisations gain from using open source tech is that it’s freely available and not distributed from a particular proprietor.

The ‘open source’ aspect refers to the code, and can be found within databases, applications and operating systems, among other software. This code can be changed to suit the needs of the business. However, being available from the public domain, this realm will have its own potential vulnerabilities that hackers could exploit.

Open source applications, for all their arrays of use cases, can be compromised if those responsible for their security aren’t on top of any possible vulnerabilities.

Linux Kernel Continues Prepping For RISC-V’s Updated Supervisor Binary Interface

RISC-V’s Supervisor Binary Interface “SBI” is the interface between the platform-specific firmware and the running operating system or hypervisor for interacting with the supervisor execution environment in the higher privileged mode. The Linux kernel has been working to support a newer version of the SBI that is more extensible moving forward.

The RISC-V Supervisor Binary Interface v0.2 now has extendability in mind with the ability to add extensions in the future while maintaining backwards compatibility. Linux kernel patches continue to be worked on in supporting this updated SBI interface for the Linux kernel.

Kubernetes administration policy made easy with brewOPA

Cloud-native computing — with such technologies as Kubernetes, service-mesh, and continuous integration and continuous delivery (CI/CD) — is revolutionizing IT. But managing can still be a major pain in the server. That’s where Open Policy Agent (OPA), an open-source Cloud Native Computing Foundation (CNCF) project, comes in. But it has its own steep learning curve. Cyral with brewOPA wants to ease their climb and make managing policies across cloud-native platforms much easier.

OPA’s very popular because it allows policy evaluation to be decoupled from an application’s core business logic. This means your policy engine internals are abstracted out, so you can easily reuse them across multiple components.

Try These 2 Things Before Choosing Your Desktop Linux OS

When macOS users decide “OK I’m done with the Apple ecosystem” and switch over to Windows, they have basically one choice for their operating system: Windows 10. When the reverse happens, people diving into Macs also have a single choice. When you take the plunge into desktop Linux, your “distribution” options expand exponentially. It can be overwhelming. Choice is the most beautiful — but sometimes paralyzing — thing about the wonderful world of Linux. If you’re curious about making that jump, wait until you’ve checked out these two fantastic resources.

Facebook Releases Open-Source Library For 3D Deep Learning: PyTorch3D

In a significant boost to 3D deep learning research, Facebook AI has released PyTorch3D, a highly modular and optimised library with unique capabilities to make 3D deep learning easier with PyTorch.

PyTorch3d provides efficient, reusable components for 3D Computer Vision research with PyTorch. Differentiable rendering has revolutionised many computer vision problems that involve photorealistic images, such as computational material design, scattering-aware reconstruction of geometry, and the materials from photographs.

Navigating man pages in Linux

Man pages provide essential information on Linux commands and many users refer to them often, but there’s a lot more to the man pages than many of us realize.

You can always type a command like “man who” and get a nice description of how the man command works, but exploring commands that you might not know could be even more illuminating. For example, you can use the man command to help identify commands to handle some unusually challenging task or to show options that can help you use a command you already know in new and better ways.

Bitcoin Startup Casa Names New CEO as Node Service Goes Open-Source

Bitcoin startup Casa is charging into 2020 with a new look – by winding down its hardware product and shuffling its front office. CEO Jeremy Welch is stepping down from the role with current head of product Nick Neuman taking the helm. CTO Jameson Lopp will remain in his current position but will join the board along with Neuman.

Welch’s decision to step away from his position was linked to personal matters and not the firm’s product decisions, Welch and Neuman said.

Meanwhile, Casa is getting rid of its node; well, at least its physical implementation.

South Korea’s government explores move from Windows to Linux desktop

What’s holding the Linux desktop back? Linus Torvalds looks to Chromebooks and Android for the future of the Linux desktop, while Linux Mint developers aren’t happy with each other.

With Windows 7 in its support coffin, some institutions are finally giving up on Windows entirely. The biggest of these may be the South Korean government. In May 2019, South Korea’s Interior Ministry announced plans to look into switching to the Linux desktop from Windows. It must have liked what it saw. According to the Korean news site Newsis, the South Korean Ministry of Strategy and Planning has announced the government is exploring moving most of its approximately 3.3 million Windows computers to Linux.
