Linux booting process
The Linux booting process begins with the BIOS performing basic checks before activating the MBR, which then loads the boot loader GRUB. GRUB executes the Linux kernel, which loads the root file system, init, device drivers, and runlevels to start Linux in single-user, multi-user, or graphical mode.
Linux booting Process
The document summarizes the 6 main steps of the Linux booting process:
1) BIOS performs initial checks and loads the master boot record (MBR) from the hard drive.
2) The MBR loads the GRUB boot loader.
3) GRUB loads and executes the Linux kernel and initrd images.
4) The kernel initializes hardware and mounts the initrd, then loads modules and root partition.
5) The init process reads /etc/inittab to determine the default runlevel and loads appropriate programs.
6) Runlevel programs like sendmail start based on the runlevel and sequence numbers in their names.
Linux booting procedure
The document discusses the Linux booting procedure. It begins with the CPU jumping to the BIOS address when the computer is turned on. The BIOS then runs tests and loads the master boot record (MBR) from the hard disk. The MBR contains the primary boot loader that loads the Linux kernel into memory. Control is then passed to the kernel which initializes processes, mounts filesystems, and launches the init process to start essential system services and reach the default runlevel.

Linux installation and booting process
The document discusses the boot process of Linux operating systems. When a computer with Linux is turned on, the boot code in ROM loads and starts the kernel. The kernel then probes the system hardware and spawns the system init process. The Linux system can boot automatically or manually. In automatic mode, the complete boot procedure occurs without input, while manual mode involves operator intervention at a certain point before initialization scripts run. The typical Linux boot process involves loading and initializing the kernel, detecting and configuring devices, creating kernel threads, optional operator intervention, running system startup scripts, and achieving multiuser operation.
Basics of boot-loader
A bootloader loads an operating system after hardware tests. It begins by initializing hardware and loading the BIOS. The BIOS then loads the master boot record from the disk, which loads secondary bootloaders. These load the operating system by accessing memory in both real and protected modes. The boot process involves loading kernel files and an initial ramdisk to start processes and mount the full filesystem.
Grub2 Booting Process
This document summarizes the Grub2 booting process. It begins with the classical BIOS booting process where the BIOS finds and loads the MBR, which contains code to load the Grub core image. The core image loads modules to access disks and file systems to load the Linux kernel. For UEFI booting, the firmware loads the bootloader from an EFI System Partition, which contains Shim and Grub files. The document outlines the key files, modules, and steps in the Grub2 booting process for both BIOS and UEFI systems.
Booting & shut down,
This document discusses the boot and shutdown processes of an operating system. It describes the six phases of the boot process: reading the boot loader, loading and initializing the kernel, detecting and configuring devices, creating kernel processes, optional administrator intervention in single-user mode, and executing startup scripts. It also discusses booting to single-user mode for recovery purposes and explains how to properly shut down a system using the shutdown command.
6 stages of linux boot process
The Linux boot process involves 6 key stages:
1. The BIOS performs initial checks and loads the master boot record (MBR)
2. The MBR loads and executes the GRUB boot loader
3. GRUB displays options to select the kernel and loads the selected kernel and initrd image
4. The kernel mounts the root filesystem, executes init, and loads drivers from initrd
5. Init determines the runlevel and loads appropriate services
6. Services are started or killed based on the runlevel using scripts in runlevel directories.
Windows 10 Operating System
The boot process of Windows 10 begins with UEFI initializing low-level hardware and loading the Windows bootloader.

Egoman produces a version for distribution solely in China and Taiwan, which can be distinguished from other Pis by their red colouring and lack of FCC/CE marks. The hardware is the same across all manufacturers.
The original Raspberry Pi is based on the Broadcom BCM2835 system on a chip (SoC), which includes an ARM1176JZF-S 700 MHz processor, VideoCore IV GPU, and was originally shipped with 256 megabytes of RAM, later upgraded (models B and B+) to 512 MB. The system has Secure Digital (SD) (models A and B) or MicroSD (models A+ and B+) sockets for boot media and persistent storage.

Securing your Kubernetes cluster_ a step-by-step guide to success !
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.

Removing Uninteresting Bytes in Software Fuzzing
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

Climate Impact of Software Testing at Nordic Testing Days
My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.
