Eclipse is an integrated development environment used primarily for Java development. It contains perspectives that arrange views and editors. Views display metadata and editors are used for editing files. The default perspective is Java. Menus provide commands for common development tasks. Views can be organized into folders and moved around. Perspectives control which menus and tools are shown.
C is a general-purpose, procedural, imperative computer programming language developed in 1972 by Dennis M. Ritchie at the Bell Telephone Laboratories to develop the UNIX operating system. C is the most widely used computer language. It keeps fluctuating at number one scale of popularity along with Java programming language, which is also
equally popular and most widely used among modern software programmers.

Francesca Gottschalk from the OECD’s Centre for Educational Research and Innovation presents at the Ask an Expert Webinar: How can education support child empowerment?
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

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

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
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.

WhatisEclipse?
In the context of computing, Eclipse is an integrated development environment (IDE) for
developing applications using the Java programming language and other programming
languages such as C/C++, Python, PERL, Ruby etc.
The Eclipse platform which provides the foundation for the Eclipse IDE is composed of plug-
ins and is designed to be extensible using additional plug-ins. Developed using Java, the
Eclipse platform can be used to develop rich client applications, integrated development
environments, and other tools. Eclipse can be used as an IDE for any programming language
for which a plug-in is available.
The Java Development Tools (JDT) project provides a plug-in that allows Eclipse to be used
as a Java IDE, PyDev is a plugin that allows Eclipse to be used as a Python IDE, C/C++
Development Tools (CDT) is a plug-in that allows Eclipse to be used for developing application
using C/C++, the Eclipse Scala plug-in allows Eclipse to be used an IDE to develop Scala
applications and PHPeclipse is a plug-in to eclipse that provides complete development tool
for PHP.
Licensing
Eclipse platform and other plug-ins from the Eclipse foundation is released under the Eclipse
Public License (EPL). EPL ensures that Eclipse is free to download and install. It also allows
Eclipse to be modified and distributed.
EclipseReleases
Every year, since 2006, the Eclipse foundation releases the Eclipse Platform and a number of
other plug-ins in June.

DownloadingEclipse
You can download eclipse from http://www.eclipse.org/downloads/. The download page lists
a number of flavors of eclipse.
The capabilities of each packaging of eclipse are different. Java developers typically use
Eclipse Classic or Eclipse IDE for developing Java applications.
The drop down box in the right corner of the download page allows you to set the operating
system on which eclipse is to be installed. You can choose between Windows, Linux and Mac.
Eclipse is packaged as a zip file.
InstallingEclipse
To install on windows, you need a tool that can extract the contents of a zip file. For example
you can use:
7-zip
PeaZip
IZArc
Using any one of these tools, extract the contents of the eclipse zip file to any folder of your
choice.
2. INSTALLATION
11. Eclipse
10
LaunchingEclipse
On the windows platform, if you extracted the contents of the zip file to c:, then you can
start eclipse by using c:eclipseeclipse.exe
When eclipse starts up for the first time it prompts you for the location of the workspace
folder. All your data will be stored in the workspace folder. You can accept the default or
choose a new location.
12. Eclipse
11
If you select "Use this as the default and do not ask again", this dialog box will not come up
again. You can change this preference using the Workspaces Preference Page. See the
Preference tutorial page for more details.

PartsofanEclipseWindow
The major visible parts of an eclipse window are:
Views
Editors (all appear in one editor area)
Menu Bar
Toolbar
An eclipse perspective is the name given to an initial collection and arrangement of views and
an editor area. The default perspective is called java. An eclipse window can have multiple
perspectives open in it but only one perspective can be active at any point of time. A user can
switch between open perspectives or open a new perspective. A perspective controls what
appears in some menus and tool bars.
3. EXPLORE WINDOWS
14. Eclipse
13
A perspective has only one editor area in which multiple editors can be open. The editor area
is usually surrounded by multiple views. In general, editors are used to edit the project data
and views are used to view the project metadata. For example, the package explorer shows
the java files in the project and the java editor is used to edit a java file.
The eclipse window can contain multiple editors and views but only one of them is active at
any given point of time. The title bar of the active editor or view looks different from all the
others.
The UI elements on the menu bar and tool bar represent commands that can be triggered by
an end user.
UsingMultipleWindows
Multiple Eclipse Windows can be open at the same time. To open a new window, click on the
Windows menu and select the New Window menu item.
Each window can have a different perspective open in them. For example you could open two
Eclipse windows one in the Java perspective and the other in the Debug perspective. The
window showing the Java perspective can be used for editing the java code and the window
showing the debug perspective can be used for debugging the application being developed.

TypicalEclipseMenus
The typical menus available on the menu bar of an Eclipse window are:
File menu
Edit menu
Navigate menu
Search menu
Project menu
Run menu
Window menu
Help menu
4. EXPLORE MENUS
16. Eclipse
15
Plug-ins can add new menus and menu items. For example when the java editor is open, you
will see the Source menu and when the XML editor is open, you will see the Design menu.
BriefDescriptionofMenus

them.
Search The Search menu presents items that allow you to search the workspace
for files that contain specific data.
Project The menu items related to building a project can be found on the Project
menu.
Run The menu items on the Run menu allow you to start a program in the run
mode or debug mode. It also presents menu items that allow you to debug
the code.
Window The Window menu allows you to open and close views and perspectives. It
also allows you to bring up the Preferences dialog.
Help The Help menu can be used to bring up the Help window, Eclipse
Marketplace view or Install new plug-ins. The about Eclipse menu item gives
you version information.

AboutViews
Eclipse views allow users to see a graphical representation of project metadata. For example
the project navigator view presents a graphical representation of the folders and files
associated with a project and properties view presents a graphical representation of an
element selected in another view or editor.
An eclipse perspective can show any number of views and editors. All editor instances appear
in a single editor area, whereas views are placed inside view folders. A workbench window
can display any number of view folders. Each view folder can display one or more views.
OrganizingViews
The following picture shows four views arranged in a view folder.
The picture given below shows the same four views arranged in two view folders.
5. EXPLORE VIEWS
19. Eclipse
18
MovingViews
To move a view from one view folder to another, just click on the view title and drag to the
title bar area of another view folder. The green line shown below is a result of dragging the
title bar of the Properties view from one view folder to the title bar area of another view folder.
The Properties view can be moved to where the green line is by releasing the mouse button
and sending out a drop event.
CreatingViewFolders
View folders can be dynamically created by dragging the title bar of a view to anywhere
outside the editor area and title bar of another view folder. As you drag the title bar around,
green lines will indicate where exactly the new view folder will be created.
Moving the drag icon to the bottom of a window allows you to create a view folder that spans
the entire width of the window. Moving the drag icon to the left or right edge of window allows
you to create a view folder that spans the entire height of the window.
21. Eclipse
20
Clicking on the Other menu item brings up the Show View dialog box that allows you to locate
and activate a view.
22. Eclipse
21
The views are organized by category. To quickly locate a view, just type the name of a view
into the filter text box. To open a view, select it and click on the OK button. The subsequent
pages of this tutorial introduce you to a number of useful views.
