The document provides information about Linux operating system. It discusses the history of Linux, how it was developed by Linus Torvalds as a free and open source alternative to Unix. It describes the key components of Linux like the kernel, types of kernels (microkernel, monolithic, hybrid), features of Linux like portability, open source nature, security etc. It also discusses popular Linux distributions like Ubuntu, Red Hat, Debian, Fedora and SUSE. Finally, it mentions some methods of installing Linux like booting from a USB or burning a live CD.
Linux was created in 1991 by Linus Torvalds as a free and open-source kernel. It has since grown significantly and is now widely used both for personal computers and in other devices like servers, embedded systems, and smartphones through Android. Some key points in Linux's history include the first Linux distribution Red Hat in 1994, the creation of desktop environments like KDE in 1996, and Android's adoption of the Linux kernel which has given it the largest installed base of any OS. There are now over 600 Linux distributions available for different use cases like Ubuntu, Debian, and Fedora for personal computers and embedded distributions for devices.
Linux has several key features: it is portable and can run on different hardware; it is open source with freely available source code that can be collaboratively enhanced; it allows for multiprogramming by executing multiple applications simultaneously and is multi-user by allowing multiple users to access resources like memory at the same time. It also has a hierarchical file system, security features like access control and encryption, and a shell program for executing OS commands.

This document discusses enumeration, which is the process of extracting information about network resources and user accounts. It provides examples of tools used to enumerate different operating systems, including NBTscan for Microsoft OS, null sessions, NetBIOS tools like nbtstat and net view, and Windows tools in Backtrack like Smb4K, DumpSec, and Hyena. For NetWare, it discusses tools like Novell Client. For UNIX systems it discusses the finger utility and using Nessus. It includes screenshots of enumerating devices with these various tools.
The UNIX system consists of two main components: utilities/commands and the kernel. Utilities are programs that can be executed, like the date and who commands. Commands refer to programs and any arguments used to change their behavior. The kernel is the core of the operating system that manages resources and performs tasks like I/O, process, device, file, and memory management. It loads utilities into memory for execution and remains resident even when utilities are not running.
Linux has several advantages such as being open source, having low costs, stability, network friendliness, performance, flexibility, security, fast and easy installation, compatibility, and multitasking. However, it also has some disadvantages like being difficult for beginners to learn, lacking certain software and games, and not supporting all hardware drivers.

It then describes several specific embedded OSs like Windows CE, VxWorks, and various Linux-based systems. It outlines some common vulnerabilities of embedded OSs like being unpatchable and having shared code with more widely used systems. Examples are given of attacks on embedded systems controlling infrastructure. The document concludes with best practices for securing embedded OSs like inventorying all systems, least privileges, encryption, and keeping systems up to date.
This document compares Linux and Windows operating systems. It provides histories of Linux, starting with the GNU project in 1984 and Linus Torvalds releasing the first Linux kernel in 1991. The evolution of Windows is also outlined from Windows 3.1 to Windows Me. The document then summarizes key differences between Linux and Windows in areas like process management, memory management, I/O management, and file management.
This document provides information on different types of free and open source software, including open source, shareware, and freeware. Open source software has open licensing that allows free distribution and modification of the source code. Shareware is proprietary trial software that has limited functionality and stops working after a trial period without payment. Freeware is fully functional software that can be used indefinitely without cost but may have some usage restrictions. Examples of each type are also provided.
An attacker with physical access to a computer or network device can easily compromise security by booting from unauthorized media like LiveCDs, USB drives, or DVDs containing hacking tools. These bootable devices allow bypassing of firewalls and access to the hard drive contents. Drive imaging software on such media poses a big risk as it can copy the entire hard drive contents without leaving a trace. Disabling auto-run features and removable media like USB drives can help reduce these risks from physical access. Encryption and centralized file storage also make drives less valuable if imaged.
The document summarizes various Linux distributions and desktop environments. It provides brief descriptions of their origins, focuses, and release dates. The distributions discussed include Slackware, Debian, SUSE, Red Hat, Knoppix, Gentoo, Arch, Fedora, CentOS, Ubuntu, Alpine, Oracle, Musix, Android, and Mageia. Desktop environments covered are Xfce, Enlightenment, KDE, GNOME, LXDE, Razor-qt, MATE, and Cinnamon.

Digital Banking in the Cloud: How Citizens Bank Unlocked Their MainframePrecisely
Inconsistent user experience and siloed data, high costs, and changing customer expectations – Citizens Bank was experiencing these challenges while it was attempting to deliver a superior digital banking experience for its clients. Its core banking applications run on the mainframe and Citizens was using legacy utilities to get the critical mainframe data to feed customer-facing channels, like call centers, web, and mobile. Ultimately, this led to higher operating costs (MIPS), delayed response times, and longer time to market.
Ever-changing customer expectations demand more modern digital experiences, and the bank needed to find a solution that could provide real-time data to its customer channels with low latency and operating costs. Join this session to learn how Citizens is leveraging Precisely to replicate mainframe data to its customer channels and deliver on their “modern digital bank” experiences.
Programming Foundation Models with DSPy - Meetup SlidesZilliz
Prompting language models is hard, while programming language models is easy. In this talk, I will discuss the state-of-the-art framework DSPy for programming foundation models with its powerful optimizers and runtime constraint system.
How information systems are built or acquired puts information, which is what they should be about, in a secondary place. Our language adapted accordingly, and we no longer talk about information systems but applications. Applications evolved in a way to break data into diverse fragments, tightly coupled with applications and expensive to integrate. The result is technical debt, which is re-paid by taking even bigger "loans", resulting in an ever-increasing technical debt. Software engineering and procurement practices work in sync with market forces to maintain this trend. This talk demonstrates how natural this situation is. The question is: can something be done to reverse the trend?
