EBPF, Service Mesh And Sidecar

The operating system is like the boss of your computer, handling security, networking, and keeping an eye on what’s happening. But tweaking or improving the core part of the operating system, called the kernel, is a bit tricky because it’s mainly focused on keeping things stable and secure. Most cool new stuff usually happens outside the core system, in what we call the user space. That’s where people add extra features or functions.

Chat with Devs | Episode 1 - Kernel and Network Tracing with eBPF |

eBPF is the kernel technology for a new generation of networking, observability and security tools. This will give attendees knowledge of how eBPF can be used to trace every action taken on a running system and know what is happening inside the kernel. The main advantage of using eBPF for tracing is that you can access almost any piece of information from the Linux kernel and your applications.

How to Empty, Delete, or Rotate Log Files in Linux?

Do you know that log files in Linux can quickly consume disk space if not managed properly? This can lead to performance issues and even system crashes. Log files? What exactly are they, and why should they matter to anyone using Linux-based systems? Log files are essential components of any Linux-based system. They are text files that contain information about system events, including errors, warnings, and other important messages.

Introducing nsuv

Here at NodeSource we are focused on fixing issues for the enterprise. This includes adding functionality and features to Node.js that are useful for enterprise-level deployments but would be difficult to upstream. One is the ability to execute commands remotely on Worker threads without the addition of running the inspector, such as capturing CPU profiles or heap snapshots.

Top 10 Linux Distros in 2023

‌‌Linux is a free and open-source Unix-based operating system. As a result of Linux's security and flexibility, its use is gaining a great deal of attention these days. A Linux distro is an operating system that relies on the Linux kernel.‌‌ A Linux server or high-end cloud device might be used on a desktop computer or laptop, but on a personal computer or laptop, it can be difficult to use. However, times have changed since then.

Best Android Emulator for Linux - 2023 Edition

On 25th August 1991, a computer-science student in Finland posted the following message on a Usenet newsgroup: “I’m doing a (free) operating system (just a hobby, won’t be big and professional like gnu) for 386(486) AT clones. This has been brewing since April, and is starting to get ready. I’d like any feedback on things people like/dislike in minix, as my OS resembles it somewhat (same physical layout of the file-system (due to practical reasons) among other things).

VS Code Linux Shortcuts for 10x Productivity

It is possible to become more efficacious and proficient with any tool when you know how to use shortcuts. Consider this for a moment. Do you think it is okay if someone repeatedly selects text by dragging through the mouse and selecting the cut option from the menu for once instead of pressing Ctrl+X? or by holding down the mouse button to copy the entire text instead of pressing Ctrl+A? There is no exception to this rule when it comes to Linux shortcuts.

Writing an eBPF/XDP load-balancer in Rust

In today’s cloud ecosystem the demands for high functioning and high performance observability, security and networking functionality for applications and their network traffic are as high as ever. Historically a great deal of this kind of functionality has been implemented in userspace, but the ability to program these kinds of things directly into the operating system can be very beneficial to performance.
