eBPF - Rethinking the Linux Kernel

Video with transcript included: https://bit.ly/3lmyeMu

Thomas Graf talks about how companies like Facebook and Google use BPF to patch 0-day exploits, how BPF will change the way features are added to the kernel forever, and how BPF is introducing a new type of application deployment method for the Linux kernel.

eBPF - Rethinking the Linux Kernel

How XDP and eBPF Use the Linux Kernel to Speed Up Network Traffic

XDP isn’t a language. Instead, XDP uses the eBPF programming language to gain access to the lower-level kernel hook. That hook is then implemented by the network device driver within the ingress traffic processing function, before a socket buffer can be allocated for the incoming packet.

Let’s look at how these two work together. This outstanding example comes from Jeremy Erickson, who is a senior R&D developer with Duo (which is now a part of Cisco). We’ll illustrate Erickson’s example by way of Ubuntu 20.04. So in order to follow along, you should have a Ubuntu instance at the ready. What we’re going to do is demonstrate XDP and eBPF working together with the help of C and Python. It’s actually quite an interesting little experiment.

How I Switched from Windows 10 to Linux Mint

This article is all about my journey on switching from Windows 10 to Linux Mint 20, how I got easily adapted to the Linux environment, and some resources that helped me to set up a perfect Desktop environment.


Ok, now I have decided to switch to Linux but here comes the first question. Which distro will satisfy my needs both in terms of GUI and other aspects? Linux is not something new to me since I have been working with RHEL based distros in my work for the past 4 years with the command-line.

I know RHEL based distros are good for enterprises but not for personalized desktop environments, at least that’s what I am thinking till now. So I started my research to find the distro that should be easy for me to use and at the same time should have good community support if in case I ran into some problem. Among many Linux distros, I drilled down my list to 4 flavors.

Before deciding the Distro it is necessary you formulate the list of tools/programs or packages needed and check if the distro you choose provides all those features.

For me, I use Linux for two main purposes: one is for my professional development work, writing articles, and second for my personal use like Video editing and Movies. Most of the popular software are created to be compatible with Windows, macOS, and Linux like Sublime TextVSCodeVLC Media PlayerFirefox/Chromium browser. Other than these software, cloud-based services make our life easy Like Microsoft Office 365 or G Suite.

Rocky Linux RC & Linux Kernel 5.12

Gwyn brings you a bucket load of Linux news this month. Rocky Linux release candidate is now out, and it seems to be cementing itself as a worthy CentOS replacement. Linux Kernel 5.12 has been released, and although mainly small fixes, there’s a couple of things worth your time, such as an Intel GPU fix. Plasma Mobile has been updated, giving a fresh coat of paint to several mobile applications. Fedora 34 is out and brings a few new improvements, as does Firefox 88 and Ubuntu 21.04, while the Pop!_OS desktop experience, Cosmic, shows us a different view.
