Je vous partage l'un des présentations que j'ai réalisé lorsque j'étais élève ingénieur pour le module 'Anglais Business ' , utile pour les étudiants souhaitant préparer une présentation en anglais sur les Design Pattern - ou les patrons de conception .
Design patterns are optimized, reusable solutions to the programming problems that we encounter every day. A design pattern is not a class or a library that we can simply plug into our system; it's much more than that. It is a template that has to be implemented in the correct situation. It's not language-specific either. A good design pattern should be implementable in most—if not all—languages, depending on the capabilities of the language. Most importantly, any design pattern can be a double-edged sword— if implemented in the wrong place, it can be disastrous and create many problems for you. However, implemented in the right place, at the right time, it can be your savior.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

Oriented-Object Design
find pertinent objects,
factor them into classes at the right granularity,
define class interfaces and inheritance hierarchies,
and establish key relationships among them.

6. Difficulties of ObjectDifficulties of Object--Oriented DesignOriented Design
A reusable and flexible design is difficult if not
impossible to get “right” the first time.
Experienced OO designers do make good designs.
Whereas , New designers are overwhelmed by the
options available and tend to fall back on non-OO
techniques they’ve used before.
What’s their difference?
02/06/2007 6
7. PatternsPatterns
When they find a good solution, they use it
again and again – pattern.
A designer who is familiar with such patterns
can apply them immediately to design
problems without having to rediscover them.

9. Design patternsDesign patterns
"Each pattern describes a problem which
occurs over and over again in our
environment, and then describes the core of
the solution to that problem, in such a way
that you can use this solution a million times
over, without ever doing it the same way
twice"

10. Design PatternDesign Pattern
Design patterns are class combinations and
accompanying algorithms that fulfill common design
purposes.
Design patterns are descriptions of communicating
objects and classes that are customized to solve a general
design problem in a particular context.
02/06/2007 10
11. In software engineering, a design pattern is a general
reusable solution to a commonly occurring problem in
software design. A design pattern is not a finished design
that can be transformed directly into code. It is a
description or template for how to solve a problem that
can be used in many different situations. Object-oriented
design patterns typically show relationships and
interactions between classes or objects, without specifying
the final application classes or objects that are involved

Two criteria
Purpose: what a pattern does
Creational: concern the process of object creation
Structural: the composition of classes or objects
Behavioral: characterize the ways in which classes or objects
interact and distribute responsibility
Scope: whether the pattern applies primarily to
classes or to objects

ABSTRACT FACTORY object creational
25. Intent

hierarchies.
Applicability
when clients should ignore the difference between
compositions of objects and individual objects
02/06/2007 25

1.Do not lead to direct code reuse
2. Complex in nature
3. They are deceptively simple
4. They are validated by experience and discussion
5. They consume more memory because of generalized
format they are written, to store any kind of data
6. Design patterns may increase or decrease the
understandability of a design or implementation
