Remote procedure calls
Remote procedure callsimnomus Remote Procedure Calls (RPC) allow clients and servers to communicate by extending the concept of local procedure calls so that the called procedure need not exist in the same address space. RPC uses message passing and stubs to conceal the underlying communication and make remote calls appear local. The RPC model involves a client, client stub, RPC runtime, server stub, and server. Stubs handle packing arguments, sending requests, and returning results to maintain transparency.
Distributed Computing
Distributed ComputingPrashant Tiwari Distributed computing deals with hardware and software systems containing more than one processing element or storage element, concurrent processes, or multiple programs, running under a loosely or tightly controlled regime. In distributed computing a program is split up into parts that run simultaneously on multiple computers communicating over a network. Distributed computing is a form of parallel computing, but parallel computing is most commonly used to describe program parts running simultaneously on multiple processors in the same computer. Both types of processing require dividing a program into parts that can run simultaneously, but distributed programs often must deal with heterogeneous environments, network links of varying latencies, and unpredictable failures in the network or the computers.

Understanding Vibrations
If not experienced, it may seem weird understanding vibes? We start small and by accident. Usually, we learn about vibrations within social. Examples are: That bad vibe you felt. Also, that good feeling you had. These are common situations we often have naturally. We chit chat about it then let it go. However; those are called vibes using your instincts. Then, your senses are called your intuition. We all can develop the gift of intuition and using energy awareness.
Energy Healing
First, Energy healing is universal. This is also true for Reiki as an art and rehab resource. Within the Health Sciences, Rehab has changed dramatically. The term is now very flexible.
Reiki alone, expanded tremendously during the past 3 years. Distant healing is almost more popular than one-on-one sessions? It’s not a replacement by all means. However, its now easier access online vs local sessions. This does break limit barriers providing instant comfort.
Practice Poses
You can stand within mountain pose Tadasana to get started.
Also, you can start within a lotus Sitting Position to begin a session.
There’s no wrong or right way. Maybe if you are rushing, that’s incorrect lol. The key is being comfortable, calm, at peace. This begins any session.
Also using props like candles, incenses, even going outdoors for fresh air.
(See Presentation for all sections, THX)
Clearing Karma, Letting go.
Now, that you understand more about energies, vibrations, the practice fusions, let’s go deeper. I wanted to make sure you all were comfortable. These sessions are for all levels from beginner to review.
Again See the presentation slides, Thx.

Deborah G Mayo

April 30, 2025
ABSTRACT: I give an introductory discussion of two key philosophical controversies in statistics in relation to today’s "replication crisis" in science: the role of probability, and the nature of evidence, in error-prone inference. I begin with a simple principle: We don’t have evidence for a claim C if little, if anything, has been done that would have found C false (or specifically flawed), even if it is. Along the way, I’ll sprinkle in some autobiographical reflections.

The role of wall art in interior designing
The role of wall art in interior designingmeghaark2110 Wall patterns are designs or motifs applied directly to the wall using paint, wallpaper, or decals. These patterns can be geometric, floral, abstract, or textured, and they add depth, rhythm, and visual interest to a space.
Wall art and wall patterns are not merely decorative elements, but powerful tools in shaping the identity, mood, and functionality of interior spaces. They serve as visual expressions of personality, culture, and creativity, transforming blank and lifeless walls into vibrant storytelling surfaces. Wall art, whether abstract, realistic, or symbolic, adds emotional depth and aesthetic richness to a room, while wall patterns contribute to structure, rhythm, and continuity in design. Together, they enhance the visual experience, making spaces feel more complete, welcoming, and engaging. In modern interior design, the thoughtful integration of wall art and patterns plays a crucial role in creating environments that are not only beautiful but also meaningful and memorable. As lifestyles evolve, so too does the art of wall decor—encouraging innovation, sustainability, and personalized expression within our living and working spaces.

- 5. Introduction The operating system is the core software component of your computer. It performs many functions and is, in very basic terms, an interface between your computer and the outside world. In the section about hardware, a computer is described as consisting of several component parts including your monitor, keyboard, mouse, and other parts.
- 6. What is an Operating System ? The operating system is the most important program that runs on a computer. Every general-purpose computer must have an operating system to run other programs. Operating systems perform basic tasks, such as recognizing input from the keyboard, sending output to the display screen, keeping track of files and directories on the disk, and controlling peripheral devices such as disk drives and printers.

- 8. Functions of Operating System Booting the computer Performs basic computer tasks eg managing the various peripheral devices eg mouse, keyboard Provides a user interface, e.g. command line, graphical user interface (GUI) Handles system resources such as computer's memory and sharing of the central processing unit (CPU) time by various applications or peripheral devices Provides file management which refers to the way that the operating system manipulates, stores, retrieves and saves data.
- 9. Types of Operating System • Real-time operating system(RTOS) - Real-time operating systems are used to control machinery, scientific instruments and industrial systems. • Single-user, single task - As the name implies, this operating system is designed to manage the computer so that one user can effectively do one thing at a time. • Single-user, multi-tasking - This is the type of operating system most people use on their desktop and laptop computers today. • Multi-user - A multi-user operating system allows many different users to take advantage of the computer's resources simultaneously. • Distributed - A distributed operating system manages a group of independent computers and makes them appear to be a single computer. • Embedded - Embedded operating systems are designed to be used in embedded computer systems. They are designed to operate on small machines like PDAs with less autonomy.
