This document provides a summary of the work and ideas of four pioneers in computing and hypertext: Vannevar Bush, Theodore Nelson, Douglas Engelbart, and Alan Kay. It focuses on Vannevar Bush and his concept of the memex, a theoretical machine that would link and allow easy retrieval of documents. The memex was inspired by Bush's earlier work on analog computers and differential analyzers. It would use microfilm and allow users to create "trails" of linked information between documents. This concept of nonlinear, linked information structures influenced later work in hypertext.
Vannevar Bush’s 1945 essay “As We May Think” described the Memex, a mechanical desk that contained entire libraries allowing its owner to create and share lasting trails of knowledge with colleagues. This talk begins with the analog computers and microfilm readers that led to this speculative essay and how those ideas influenced digital computing pioneers in the 1960-70s: Doug Engelbart — the inventor of personal workstation, Ted Nelson — the creator of hypertext and visions of digital world containing all the world’s literature, and Alan Kay — whose DynaBook vision foreshadowed the form factors and user interface we carry around in our backpacks and pockets today.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

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.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

stop-motion photography. Forms a partnership with Kenneth
Germeshausen, an MIT research affiliate to develop further uses for the
stroboscope. Edgerton receives his D.Sc. in electrical engineering from MIT.
15. Paul Kahn | 15
Concept: Miniaturization and duplication of knowledge
— Herbert George (H.G.) Wells, novelist, social commentator, science
fiction writer: The Time Machine, The Invisible Man, War of the Worlds
— Fabian socialists and pacifist
— essay “The World Brain” (1937), an essay for the
Encyclopédie Française, proposed that the libraries
of the world would soon be available to everyone on
reels of microfilm
(See https://sherlock.ischool.berkeley.edu/wells/world_brain.html)
16. Paul Kahn | 16
Concept: Miniaturization and duplication of knowledge
— There is no practical obstacle whatever now to the creation of an efficient
index to all human knowledge, ideas and achievements, to the creation, that
is, of a complete planetary memory for all mankind. And not simply an
index; the direct reproduction of the thing itself can be summoned to any
properly prepared spot. A microfilm, coloured where necessary, occupying
an inch or so of space and weighing little more than a letter, can be
duplicated from the records and sent anywhere, and thrown enlarged upon
the screen so that the student may study it in every detail.

Rapid Selector Concept (1930s)
— Sound-on-film development of composite 35mm film techniques throughout
the 1920s
— Emmanuel Goldberg of Zeiss Ikon (Dresden) demonstrated high-density
microfilm readers and selectors in Brussels (1931)
— Harold Edgerton’s stroboscope (1931) for high-speed photography was used
for rapid detection and re-photographing of coded frames.
— H.G. Wells essay “The World Brain” (1937) proposed that the libraries of the
world would soon be available to everyone on reels of microfilm
— Chester Carlson’s (1938) combination of electrostatic printing and
photography (xerography) to capture pages on film

A machine to rapidly
select documents recorded
as microfilm images on
reels of 35 mm movie film
Coding of document topics
as dot patterns on film
Strobotron to fire photo
cell detectors matching a
topic pattern “mask”
19. Paul Kahn | 19
Publication of “As We May Think” (summer, 1945)
— Bush writes “Mechanization and the Record” in 1939 and files it away
— The machine he describes as the Memex (memory extender) is a microfilm
rapid selector miniaturized into a desk
— Features he imagines include projection of pages onto dual screens, photo
annotation, xerographic input and recording trails between documents
— He mentions a machine to translate voice into text (Vocoder) similar to a
device demonstrated at the 1939 World’s Fair in New York
— He describes a forehead-mounted miniature camera (Walnut camera) to
permit “hands-free” photographic recording in the laboratory
20. Paul Kahn | 20
Concept: A machine that extends memory
— Consider a future device for individual use, which is a sort of mechanized
private file and library. It needs a name, and, to coin one at random,
"memex" will do. A memex is a device in which an individual stores all his
books, records, and communications, and which is mechanized so that it
may be consulted with exceeding speed and flexibility. It is an enlarged
intimate supplement to his memory.
It consists of a desk, and while it can presumably be operated from a
distance, it is primarily the piece of furniture at which he works. On the top
are slanting translucent screens, on which material can be projected for
convenient reading. There is a keyboard, and sets of buttons and
levers. Otherwise it looks like an ordinary desk.
21. Paul Kahn | 21
Concept: Literature accessed and linked by a machine
— Wholly new forms of encyclopedias will appear, ready made with a mesh of
associative trails running through them, ready to be dropped into the
memex and there amplified. The lawyer has at his touch the associated
opinions and decisions of his whole experience, and of the experience of
friends and authorities. The patent attorney has on call the millions of
issued patents, with familiar trails to every point of his client's interest. The
physician, puzzled by a patient's reactions, strikes the trail established in
studying an earlier similar case, and runs rapidly through analogous case
histories, with side references to the classics for the pertinent anatomy and
histology. The chemist, struggling with the synthesis of an organic
compound, has all the chemical literature before him in his laboratory, with
trails following the analogies of compounds, and side trails to their physical
and chemical behavior.
22. Paul Kahn | 22
Concept: navigational links as trails
— The historian, with a vast chronological account of a people, parallels it with
a skip trail which stops only on the salient items, and can follow at any
time contemporary trails which lead him all over civilization at a
particular epoch. There is a new profession of trail blazers, those who find
delight in the task of establishing useful trails through the enormous mass of
the common record. The inheritance from the master becomes, not only his
additions to the world's record, but for his disciples the entire scaffolding by
which they were erected.

Vannevar Bush Legacy
— Bush ends his post-war governmental career as the founder of the National
Science Foundation (NSF)
— Rapid Selectors built in the 1950s and 1960s for the Library of Congress,
Department of Navy, Central Intelligence Agency all fail to operate properly.
— “As We May Think” influences the work of J.C.R. Licklider, Ted Nelson and
Douglas Engelbart
— “As We May Think” is reprinted and taught in Information (Library) Science
from 1960s onward.
— Computer Science Hypertext research literature refers to Bush’s essay as the
earliest example of hypertext concept, starting in the 1980s.
30. Paul Kahn | 30
Theodor Holm Nelson (b. 1937)
— Inventor of new poetic language including
• hypertext *
• hypermedia
• cybercrud
• softcopy
• electronic visualization
• technoid
• docuverse
• Transclusion
* first appears in 1965: “A File Structure for the Complex, the Changing
and the Indeterminate”
31. Paul Kahn | 31
Concept: Simple Hypertext (1965)
32. Paul Kahn | 32
Ted Nelson
— Collaborator on Hypertext Editing System (HES) at Brown University (1972)
— Author of “underground” computer books
• Computer Lib / Dream Machine (1974)
• The Home Computer Revolution (1977)
• Literary Machine (1981-1993)
— Introduced the concepts of Project Xanadu in the 1980s through many
talks and articles in Creative Computing, Byte, and other magazines
— Xanadu system project at Autodesk in late 1980s
33.
34. Paul Kahn | 34
Concept: universal access, follow and publish links
— At your screen of tomorrow you will have access to all the world’s
published work: all the books, all the magazines, all the photographs, the
recordings, the movies. (And to new kinds of publications, created especially
for the interactive screen.)
You will be able to bring any published work to your screen, or any part
of a published work.
You will be able to make links – comments, personal notes, or other
connections – between places in documents, and leave them there for others
(as well as yourself) to follow later. You may even publish these links.
from Literary Machines
35. Paul Kahn | 35
Concept: digital rights management & micropayments
— Royalty to each publisher will be automatic, as materials are delivered
over the network. Each piece delivered will be paid for automatically, from
the user’s account to the publisher’s account, when the user receives the
piece sent for.
Any document may quote another, because the quoted part is brought – and
bought – from the original at the instant of request, with automatic royalty
payment and credit to the originator.
36. Paul Kahn | 36
Harsh critiques of the file hierarchy and WWW
— Calling a hierarchical director a "folder" doesn't change its nature any
more than calling a prison guard a "counselor".
— Hierarchical directories were invented around 1947 – I should check
this – when somebody said, "How are we going to keep track of all these
files? "Gee, why don't we make a file that's a list of filenames?" And
that was the directory. It's a temporary fix that doesn't scale up.
— The Web is the minimal concession to hypertext that a sequence-and-hierarchy
chauvinist could possibly make.
— Recent books: Geeks Bearing Gifts and Possiplex,
both published via Lulu.com

Douglas Engelbart (1925-2013)
— Educated at University of California,
Berkeley
— Worked at Stanford Research Institute (SRI)
— Published his first theoretical paper,
Augmenting Human Intellect: A Conceptual
Framework in 1962
39. Paul Kahn | 39
Concept: Augmenting Human Intellect
— By "augmenting human intellect" we mean increasing the capability of a
man to approach a complex problem situation, to gain
comprehension to suit his particular needs, and to derive solutions to
problems. Increased capability in this respect is taken to mean a mixture of
the following: more-rapid comprehension, better comprehension, the
possibility of gaining a useful degree of comprehension in a situation that
previously was too complex, speedier solutions, better solutions, and the
possibility of finding solutions to problems that before seemed insoluble.
40. Paul Kahn | 40
Concept: engineering tools for complex situtations
— And by "complex situations" we include the professional problems of
diplomats, executives, social scientists, life scientists, physical
scientists, attorneys, designers–whether the problem situation exists
for twenty minutes or twenty years. We do not speak of isolated clever tricks
that help in particular situations. We refer to a way of life in an integrated
domain where hunches, cut-and-try, intangibles, and the human "feel for a
situation" usefully co-exist with powerful concepts, streamlined terminology
and notation, sophisticated methods, and high-powered electronic aids.
41. Paul Kahn | 41
oNLine System (NLS)
— Augmentation Research Center developed
oNLine System (NLS) in 1968
— Focus on developing new Human-Computer
Interaction (HCI) models and tools
— Introduced new concepts
• Computers Supporting Collaborative Work
(CSCW)
• Bootstrapping – using the development
group to test new tools
• Co-evolution – the co-dependent evolution
of the software interface and human
behavior
42. Paul Kahn | 42
NLS (continued)
— Developed the Mouse (analog pointing device) and Chord (5-finger)
keyboard
— The NLS system (circa 1968) also included:
• Mixture of text and graphics
• Hypertext links
• Outline processing
• View control of text and graphic data
• Collaborative work space
• Shared pointing device
• Video conferencing

(see Clip #5)
45. Paul Kahn | 45
Engelbart after 1968
— NLS failed due to timesharing computer technology: the more people
using it, the slower it responded.
— Many researchers from his laboratory moved to Xerox Palo Alto
Research Center (PARC) in 1971, where the mouse and the personal
workstation was (re)invented
— Engelbart developed Augment, a commercial timesharing system for
documentation in the aerospace industry
— Engelbart worked on the first network protocols for the ARPAnet, the
foundation of the current Internet (early 1970s)
— Engelbart created Bootstrap Institute in 1999,

from “A Personal Computer for Children of All Ages”
— Imagine having your own self-contained knowledge manipulator in a
portable package the size and shape of an ordinary notebook. Suppose it had
enough power to outrace your senses of sight and hearing, enough capacity
to store for later retrieval thousands of page-equivalents of reference
materials, poems, letters, recipes, records, drawings, animations, musical
scores, waveforms, dynamic simulations, and anything else you would like to
remember and change.
We envision a device as small and portable as possible which could both
take in and give out information in quantities approaching that of
human sensory systems. Visual output should be, at the least, of higher
quality than what can be obtained from newsprint. Audio output should
adhere to similar high-fidelity standards.
51. Paul Kahn | 51
from “A Personal Computer for Children of All Ages”
— There should be no discernible pause between cause and effect.
One of the metaphors we used when designing such a system was that of a
musical instrument, such as a flute, which is owned by its user and responds
instantly and consistently to its owner’s wishes. Imagine the absurdity of a
one-second delay between blowing a note and hearing it!
These civilized desires for flexibility, resolution, and response lead to
the conclusion that a user of dynamic personal medium needs several
hundred times as much power as the average adult typically enjoys from
timeshared computing. This means that we should either build a new
resource several hundred times the capacity of current machines and share it
(very difficult and expensive), or we should investigate the possibility of
giving each person his own powerful machine. We choose the second
approach.

Fast-forward 25 years
— All newly created music, books, photographs, film/video are digital
— Over 70% have network access in North America and EU countries
— Over 90% have a mobile device: a mobile phone
— Over 25-50% have a “Smartphone”
— The Internet is becoming the “Cloud”

Dream of the Digital Library
— Wikipedia collectively written in many languages
— Digital National Libraries and Archives today: collections of bibliographical
records, images, audio-visual archives and scanned pages
— Private digital libraries by subscription: news, business, science, law, finance
66. Paul Kahn | 66
Dream of the Digital Library
— Most “free” digital content supported by advertisements
— Most people view content on journalism sites, blogs, social networks, tweets
and video clips
— Google Books (books.google.com)
Nearly every book I have written is in Google Books, but the author does not
have the right to see most of them (snippet view)
— Complex digital rights issues and payment schemes unresolved
