Perf is a performance analysis tool for Linux. It instrumentalizes events setup by the kernel to monitor applications. While it makes sense that kernel events are available to a tool implemented inside the kernel, how can perf know about CPU metrics, such as the number of instructions a program executed?

This article is about device communication in embedded systems. It will compare and explain the different types of device communication in embedded systems (I2C, UART, SPI, CAN) to beginners who want to learn how device communication works and which one to use.

This article aims to give an in depth description on EUCLEAK, an attack that was discovered by NinjaLab. Focusing on how side-channels attacks were used to exploit a vulnerability found in ECDSA implementation in YubiKey 5 Series and to reverse engineer the ECDSA algorithm.

Introduction to USB keyboard protocol

This article describes the implementation of collision avoidance algorithms in real-time autonomous vehicles.

CPU manufacturing is so complex that the chips often have imperfections. Some cores do not work or must run at lower speeds. Manufacturers test them and sell based on performance.

This article will explain in detail how to optimize regular expressions. It will explore various techniques to reduce backtracking and improve speed, enabling the writing of more efficient and high-performance regex.
