Linux fundamental - Chap 16 System Rescue
This document discusses various methods for entering system rescue mode in Linux, including:
1) Booting into single-user mode by entering "init 1" at the GRUB prompt or editing the kernel line to add "init=/bin/bash".
2) Securing single-user mode by editing /etc/inittab to require a password for the root login.
3) Bypassing the single-user password by editing the kernel line to remove "init=/bin/bash".
4) Preventing kernel line editing by adding a GRUB password in the /boot/grub/menu.lst file.
5) Rescuing the system using a Linux rescue CD to mount the filesystem in read
Linux fundamental - Chap 11 boot
The document discusses the Linux boot process and service management. It describes the stages of boot including the BIOS, boot loader, kernel, and init process. GRUB is described as a common boot loader, its configuration files and installation process. The roles of initrd, init, and runlevels in starting and managing system services are covered. Finally, alternatives to the traditional init system like Upstart are introduced.
Backup, Restore, and Disaster Recovery
The document discusses various backup, restore, and disaster recovery strategies for MongoDB databases. It outlines options for backing up data using mongodump, copying database files, or taking filesystem snapshots. For restoring, it recommends using mongorestore which can replay oplog entries for point-in-time recovery. It also stresses the importance of testing restores. For disaster recovery, it suggests using replica sets for redundancy across multiple data centers and regions to avoid single points of failure.

NVIDIA GPUs contain functional units called Streaming Multiprocessors (SMs) that execute threads in groups. Blocks of threads are scheduled on SMs, and multiple blocks can be assigned to an SM depending on resources. Grid dimensions that are divisible by the number of SMs can maximize SM utilization, while block dimensions that are multiples of 32 can maximize utilization of warps of 32 threads that SMs execute as a group.

Bootloader and bootloading
1. The booting process begins with the BIOS performing checks and finding a bootable device from which to load an operating system. It loads the master boot record which contains the boot loader like GRUB.
2. The boot loader loads the Linux kernel from the hard disk into memory and passes control to it. The kernel then launches the init process to perform startup tasks and launch other processes.
3. Init controls the runlevels which determine the system configuration and processes that are running. It is responsible for system startup and shutdown processes.
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.
Hardware software specification
The document outlines the system configuration for a computer, including the hardware of a Pentium III processor, 256MB RAM, 20GB hard drive, 1.44MB floppy drive, standard keyboard, and SVGA monitor. The software configuration is specified as Windows 95/98/2000/XP, with Tomcat 5.0/6.X as the application server, and front-end technologies of HTML, Java, and JSP alongside JavaScript, JSP server-side scripting, MySQL 5.0 database, and JDBC database connectivity.
Linux booting process
BIOS performs system integrity checks at startup and loads the boot loader GRUB. GRUB displays a menu to select the operating system and kernel version, and passes control to the kernel. The kernel mounts the root file system and executes the init process, which then loads the default run level configured in /etc/inittab to start processes for multi-user mode with a full network or graphical user interface depending on the level.
Assembly programming lesson 2
This document discusses CPU modes in assembly programming. It covers real mode which has a 1MB memory limit and uses segment:offset addressing. Protected mode is then introduced, which enables full CPU features, new segmentation addressing, paging, and memory protection. The document provides an example of code to jump from real mode to protected mode using a bootsector that loads a file called pm_setup before switching to protected mode.
Embedded_Linux_Booting
The embedded Linux boot process involves multiple stages beginning with ROM code that initializes hardware and loads the first stage bootloader, X-Loader. The X-Loader further initializes hardware and loads the second stage bootloader, U-Boot, which performs additional initialization and loads the Linux kernel. The kernel then initializes drivers and mounts the root filesystem to launch userspace processes. Booting can occur from flash memory, an eMMC/SD card, over a network using TFTP/NFS, or locally via UART/USB depending on the boot configuration and available devices.
Deployment Strategies
- The document provides guidance on deploying MongoDB including sizing hardware, installing and upgrading MongoDB, configuration considerations for EC2, security, backups, durability, scaling out, and monitoring. Key aspects discussed are profiling and indexing queries for performance, allocating sufficient memory, CPU and disk I/O, using 64-bit OSes, ext4/XFS filesystems, upgrading to even version numbers, and replicating for high availability and backups.
Deployment Strategies (Mongo Austin)
The document discusses best practices for deploying MongoDB including sizing hardware with sufficient memory, CPU and I/O; using an appropriate operating system and filesystem; installing and upgrading MongoDB; ensuring durability with replication and backups; implementing security, monitoring performance with tools, and considerations for deploying on Amazon EC2.
ZFS test
This document summarizes tests performed on ZFS file systems with compressed and uncompressed storage on a PC and Amazon EC2. It describes:
1) Alignment tests using Bowtie2 on PC that showed no difference in CPU usage or memory between compressed and uncompressed storage.
2) Alignment tests on EC2 that initially failed due to insufficient memory but succeeded when splitting the jobs across fewer CPU cores.
3) I/O performance tests showing read and write speeds were similar or faster for compressed storage, with efficiency gains from compression.
4) Disk usage showed more available storage was used on compressed systems after data was compressed.
Kvm optimizations
This document summarizes a presentation on KVM optimizations and best practices for both desktop and datacenter use. It covers tools like Libvirtd and virt-manager, virtio drivers, image backends like Qcow2, CPU pinning and cgroups, networking configurations, desktop sharing with SPICE, and challenges in cloud deployments around live migration, storage, and network isolation.
Linux : Booting and runlevels
The document discusses the Linux boot process and runlevels. It begins by explaining how to view boot messages and locate hardware information in the logs. Next, it provides a high-level overview of the boot sequence, from the firmware loading the kernel to init executing scripts. It then explains the different runlevels (0-6) and how they determine available features. Finally, it discusses how to check, change, and manage runlevels using tools like chkconfig, init, telinit, and shutdown.
MongoDB: Backup, Restore, and DR
This document discusses backup, restore, and disaster recovery options for MongoDB databases. It covers topics such as mongodump for backups, filesystem snapshots, replication for disaster recovery, and restoration procedures for both online and offline servers. Tips are provided for mongodump/restore operations and cleaning up snapshots.

This PPT shares some information on what is booting process and different stages in it. Importance of BIOS and BootROM. Steps involved for loading kernel into RAM. What is the importance of init RAM disk (initrd), when 1st user space application is started and who will create init process.
Computer Organisation Part 2
This document discusses various components of a computer system including magnetic drum memory, optical drives like CD-ROM and DVD-ROM, hard disks, video display units or monitors, and printers. It provides details on the read/write speeds of CD and DVD drives, the storage capacities of CDs and DVDs of different types, and the functioning of cathode ray tube (CRT) monitors and different types of printers like dot matrix and daisy wheel printers.
File system performance
Disk performance is critical for overall system performance as disks are much slower than other components. Two key techniques for improving disk performance are block caching and block read ahead. Block caching stores frequently accessed disk blocks in faster RAM. Block read ahead preemptively loads sequential blocks from disk into cache before they are requested. Example file systems discussed include CD-ROM (using ISO 9660), MS-DOS (using FAT16), and UNIX (using a hierarchical structure with everything treated as a file).

Computer Organisation Part 1
SRAM uses binary cells (BCs) made of flip-flops to store 1-bit values. A 2x4 decoder selects which BC to read from or write to based on address lines. During read, the selected BC's value passes through an AND gate to the output. During write, a new value is written to the selected BC through the AND gate.
Holographic Environment Amazing Augmented Reality
The document discusses holographic environments and tele-immersion technology. It describes how holograms can be used to create 3D images and allow interaction in simulated environments. The technology could be used to meet remotely and interact with holographic images of other people, blurring the lines between real and virtual. Several groups are working to develop national initiatives for tele-immersion to advance this technology.
ISO OSI Model
The ISO - OSI Model document discusses the OSI model, which was created by the International Organization for Standardization to establish a standard for how systems use protocols to communicate over a network. The OSI model defines seven layers of network functionality, each building on the layers below. It allows different hardware and software components from different vendors to communicate by standardizing network communication. The model breaks network communication into smaller, simpler parts that are easy to develop and facilitates interoperability between devices.

Webinar: Designing a schema for a Data Warehouse
Are you new to data warehouses (DWH)? Do you need to check whether your data warehouse follows the best practices for a good design? In both cases, this webinar is for you.
A data warehouse is a central relational database that contains all measurements about a business or an organisation. This data comes from a variety of heterogeneous data sources, which includes databases of any type that back the applications used by the company, data files exported by some applications, or APIs provided by internal or external services.
But designing a data warehouse correctly is a hard task, which requires gathering information about the business processes that need to be analysed in the first place. These processes must be translated into so-called star schemas, which means, denormalised databases where each table represents a dimension or facts.
We will discuss these topics:
- How to gather information about a business;
- Understanding dictionaries and how to identify business entities;
- Dimensions and facts;
- Setting a table granularity;
- Types of facts;
- Types of dimensions;
- Snowflakes and how to avoid them;
- Expanding existing dimensions and facts.
