I am explaining the concept of promise with help of OMPromise Library written in ObjC. In the end I present a non complete Swift implementation of Promises concept that I hacked together in couple of hours.
In this lecture we will discuss about another flow control method – Loop control.
A loop control is used to execute a set of commands repeatedly
The set of commands is called the body of the loop
MATLAB has two loop control techniques
Counted loops - executes commands a specified number of times
Conditional loops - executes commands as long as a specified expression is true
Over recent years, JavaScript has increasingly gained popularity, partly due to libraries that are developed to make JavaScript apps/effects easier to create for those who may not have fully grasped the core language yet.
While in the past it was a common argument that JavaScript was a basic language and was very ‘slap dash’ with no real foundation; this is no longer the case, especially with the introduction of high scale web applications and ‘adaptations’ such as JSON (JavaScript Object Notation).
Swift & ReactiveX – Asynchronous Event-Based Funsies with RxSwiftAaron Douglas
This is an introduction to reactive concepts using Swift specifically with ReactiveX’s implementation, RxSwift. ReactiveX is an API for asynchronous programming with observable streams originally implemented with .NET and LINQ. ReactiveX is a combination of the best ideas from the Observer pattern, the Iterator pattern, and functional programming.
You’ll learn about all the basic moving parts of RxSwift and why you want to use it in your application.

The critical routines within signal processing algorithms are typically data intensive and iterate many times, carrying out the same functions on multi-dimensional arrays and input streams. These routines use the vast majority of an implementation’s resources, and for the longest time over the course of the algorithms execution. Such routines are classed as Nested-Loop Programs. Whether the implementation is software running on a processor or a higher performance customized hardware implementation, there is always a tradeoff between the throughput performance (execution-time) and the resources used such as the amount of processor memory and registers in a software implementation or the gate-count in a hardware implementation. This article shows the reader techniques and methods for manipulating a signal processing algorithm, in particular those conforming to a Nested-Loop Program, and the different generic implementation architectures along this tradeoff spectrum, as well as the different methods for describing and analyzing an algorithm implementation. Each of these methods for describing an algorithm is shown to correspond to a different abstraction-level view and as such exposes different features and properties for ease of analysis and manipulation. Manipulation techniques, mainly algorithmic-transformations are described and it is shown how these transformations take an implementation and form a new one at a different point in the trade-off spectrum of resources used versus throughput by performing calculations in a different order and a different way to arrive at the same result.

Client-server architecture (clientserver) is a network architecture .pdffabmallkochi
Client-server architecture (client/server) is a network architecture in which each computer or
process on the network is either a client or a server. Servers are powerful computers or processes
dedicated to managing disk drives (file servers), printers (print servers), or network traffic
(network servers). Develop a simple calculator program using client server architecture. Client
should accept the input, send It to the server, process/calculate it and send it back to client.
Introduction and problem definition Problem solving approach Implementation Results and
Analysis Conclusion
Solution
Hi here am make a program on window based application in C# only basic calculator for adding
of two numbers;
B4.1.:---it basic calculator for adding two integer value in c# which based a window based
software using client and server resposne.
B4.2:--Problem solving approach is very simple i.e. only sum of two digit i have made . which is
very basic.
B4.3:- Implimention
first a impliment a client side i.e. window input form in which i take value for calculating:
and here i add the code for client side.
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;

public Form1()
{
InitializeComponent();
}
Class1 obj = new Class1();
private void button1_Click(object sender, EventArgs e)
{
try
{
double num1 = Convert.ToInt32(textBox1.Text);
double num2 = Convert.ToInt32(textBox2.Text);
ChannelServices.RegisterChannel(new TcpClientChannel());
obj = (Class1)Activator.GetObject(typeof(Class1), \"tcp://localhost:3128/Hello\");
label3.Text = obj.Cal(num1, num2).ToString();
}
catch(System.Net.Sockets.SocketException)
{
MessageBox.Show(\"server not available\");
}
}
}
}
after this i implimented the server side in which i made a console window as server
the code of server side is:-

using System.Runtime.Remoting;
using System.Runtime.Remoting.Channels;
using System.Runtime.Remoting.Channels.Tcp;
using Dll;
namespace server
{
class Program
{
static void Main(string[] args)
{
TcpServerChannel channel = new TcpServerChannel(3128);
ChannelServices.RegisterChannel(channel);
RemotingConfiguration.RegisterWellKnownServiceType(typeof(Class1), \"Hello\",
WellKnownObjectMode.SingleCall);
Console.WriteLine(\"Press Enter To stop server\");
Console.ReadLine();
}
}
}
after this i made class for calculation of two number .i.e. addition method implimentation in this
class
the code is:-
using System;
using System.Collections.Generic;
using System.Text;

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

Removing Uninteresting Bytes in Software FuzzingAftab Hussain
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.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).
