Introduction to the Presentation – 1
•
To encourage the use of computers by:
–
older people
–
and by younger ones computers fully.
who have not embraced
•
PREVIOUS computer design (1980s-90s):
–
Aimed mostly at use by young graduates (i.e. users with no health or communication issues)
–
Computers were:
•
Hard to use
•
Had slow, awkward text-based screens/interfaces (such as ‘cd’, to change folder/directory) … rather than current with images.
friendly, graphical screens
Introduction to the Presentation – 2
• • •
Today, the aim , if not the reality, is for everyone on the planet to become IT-literate, and enthusiastic about it. Major software systems such as Windows 7, Linux or Word are available in most international languages (English, French, Russian, and Arabic); although there are exceptions such as those used by Native Americans, like the Apache.
NOTE: Although the Microsoft majority of single user computers are compatible PCs, the ideas expressed in this presentation are equally applicable to Apple Mac (and UNIX) users, who quite rightly continue to support these excellent technologies.
Brief History of IT
•
My first IT experience:
– – – –
A Burroughs’s main-frame in 1977 at Warwick University Developing an industrial simulation software system Using the Programming language: ALGOL 60.
The computer was as big as a detached house , only had the power of a single modern PC (and was used by everyone there)
•
Often, programs were:
– –
submitted overnight in batch mode on a set of punched cards bound by a rubber band (as students were not initially given a monitor)
•
Only a few universities/large major employers (mostly Finance/Defence) owned a main-frame computer
Progress
•
Things change quickly: ‘In 1980 there were 720,000 personal computers in the world; by 1990 there were 50 million, and their average power had increased a hundredfold’ [pg 280, Kieran & Lewis]
Existing Computers and Software
•
The four PC facilities I will discuss today are:
–
The Internet
–
–
Microsoft Office and
–
The Long Eaton Library Online Resources
The Internet
•
The Internet is:
–
Worldwide
–
Multimedia (text, sound, pictures, video)
–
A computer-based library
–
Hosted on many server computers
–
Available on any internet-enabled device .
•
The examples that follow give a brief insight into things that are possible…
•
Internet Examples – 1
Art lovers
– –
see the pictures at: the Louvre ( www.louvre.fr
), Paris; or the National Gallery, London ( www.nationalgallery.org.uk
) Although nothing can replace the experience of an actual visit (but it does save on sore feet…)
•
Information
–
quickly search for (and sometimes find) information via search engines, such as: www.google.com
, www.yahoo.com
, www.lycos.com
, www.altavista.com
, www.ask.com
(where ask.com accepts English-like questions).
–
For example, you can investigate company details, or find which courses a college provides, next term.
Often a more accurate, up-to-date and faster means of research than the traditional one of using libraries . But not always.
•
Internet Examples – 2
Online free encyclopaedia
– –
– www.wikipedia.org
Aims to be the largest ever (for our species) Can be edited by ‘registered users’.
•
Order your weekly shop
–
Delivered to your front door
–
Just choose a supermarket… ( www.asda.co.uk
schemes, currently only £5 for online shopping & delivery) www.tesco.co.uk
have annual internet only-discount – and others…
–
But too little, and too much?
Too little Too much - with the currently small customer base, it may not be economic for the retailer; - many people may not pay for something, that historically they have done themselves, for free?
Is it really quicker – especially for your first on-line shop effort, when a lot of information must be entered?
Is it less socially rewarding – low on exercise, and more likely to meet friends in the super-market?
But - buying online may be 10% cheaper (e.g. insurance?)

) holds several million out of print books (usually old ones, where the author is dead), which can be downloaded free, in a variety of computer formats.
•
Internet Examples – 10
Bank online Most banks provide online banking, enabling you to:
– – – –
(e.g. www.halifax.co.uk
check your accounts transfer money between accounts automate overdraft warnings ) setup direct debits (all from the comfort of your own home…)
•
Video conferencing (e.g. www.skype.co.uk
) – but Image size and the refresh rate may vary).
Useful for:
–
Contacting family members abroad (even New Zealand).
–
Medical exchange ; used by doctors in India and Australia, for remote diagnosis.
–
Cheap phone calls by combining technologies: use skype on a mobile phone, via free library Wi-Fi - to phone your mum in China! Or, you can just use skype for free phone calls.

Email - 1
•
Email:
–
www.hotmail.co.uk
–
www.yahoo.co.uk
–
www.gmail.com
and others
–
Provides a free way, for anyone who can write (in English, French, Arabic, Russian…) and with an internet enabled device, to communicate with anyone else , worldwide.
Email - 2
•
… is similar to letter writing , but has the following advantages:
–
Speed: most (but not all) emails arrive within a few minutes .
–
Cost: As a stamp and envelope are not required , email is cheaper* (and you don’t get wet going to the post-box in January).
* Is free, unless you count the cost of being on line (internet subscription, equipment costs, electricity…)
Email - 3
•
… enables ‘threaded communication’ So you can easily see what was written to you , while composing your reply, for example:
– – –
‘a’ wrote 5.36PM Sat ‘b’ replied 6.39PM Sat ‘a’ responded 11.57PM Sat, etc...
•
… enables attachments that hold further information ; For example:
– –
a book could be sent to a prospective publisher, or a daughter (living in Rome) could send a picture (of her new boy-friend!) to her father (living in Derby).
•
… can provide grammar and spelling checkers, to check what you send - usually quicker (if less comprehensive) than the traditional verbose dictionary.
Microsoft Office
•
Microsoft Office Provides the following widely used tools :
–
Word – to create documents in a variety of languages, with a spelling/grammar checker.
–
Excel - a spreadsheet (financial/maths use); can even be used for household accounts.
–
PowerPoint - used to create electronic slide shows ( like this one!
)
– – –
Publisher – a simple, automated way to create small personalised web sites.
Access – a simple to use database; could be used to maintain an address book.
Adobe – enables creation of pretty (professional standard) documents containing both text and complex graphics. Although Adobe is not always part of Office.
Long Eaton Library - Online Resources
LEL contains a wide variety some of which are: of information
• • • • • •
Ancestry Britannica – Full history website.
– A general purpose encyclopaedia.
COBRA – A business-related encyclopaedia.
Grove Art – An encyclopaedia of visual art.
Oxford Language Dictionaries coffee at an Italian café.
– these include approximate translation facilities (not accurate enough for important legal documents, or international trade deals), should you wish to order a Theory Test Pro – for those striving to pass their Car Driving Theory Test.
Further Ideas - 1
It is possible to: 1.
plug a microphone into your computer 2.
then speak to it… … and get it to respond to your voice commands. One example would be the Voice Recognition Software, ‘Dragon Naturally Speaking’ ( www.shop.nuance.co.uk
? Although Colds can alter your voice).
For instance, to quit Microsoft Word: 1) instead of clicking File->Exit, 2) you could just say: (Alas, it can’t “ File Exit ”.
make the tea or coffee, yet…).
Further Ideas - 2
•
Could computers be used for online voting for Local, National, or even European elections?
Thus, hopefully improving turnout?
Then perhaps, referenda would be held more frequently - hence creating a democracy more like the ideals of Plato, in Ancient Greece?
Further Ideas - 3
•
Real-time online messages Computers enable online messaging (such as www.ebuddy.com
or www.paltalk.com
), as built into FaceBook and Windows 7. So, a screen-based real-time text conversation, like:
–
A: ‘How are you?’
– –
B: ‘I am Fine – How are you?’ A: ‘Life is good – would you like to meet soon?’ … can be done in real time (‘live’), just by typing . I have heard of online messaging being used between partners, where one is fighting in a remote area of Afghanistan, with the other living in England.
Further Ideas - 4
•
TV to PC : Convert your TV into a simple computer, by adding an extra card to the TV:
– – –
www.raspberrypi.org/ http://www.bbc.co.uk/news/technology-16316439 http://www.technologytell.com/gadgets/90585/non developer-raspberry-pi-computers-may-be-available in-q3-2012/ … and this is not expensive to do!
This conversion could save money for someone wishing to do simple home computing, where they currently own a TV, but don’t have a PC.
Further Ideas - 5
•
Mobility/dexterity issues There are many features in Windows 7 to make using computers easier:
–
Using a PC/other device by touching a screen Use Multi-touch, or a touch-sensitive screen/tablet (such as the HP Touch Smart TX2Z, which recognises natural gestures).
:
–
Windows Mobility Centre : Context menus, glow-key feedback (immediately showing the change when a feature is used).
–
Ease of Access Center : Magnifier, Narrator, On-Screen Keyboard & High Contrast.
The Future - 1
•
(Hard to predict!)
–
Will computer displays be holographic ?
(like those ‘Star Trek’) truly
– –
3-D and Will robots be built that you can fall in love with?
(like those of the Isaac Asimov novel, ‘I Robot’) Will Turing’s challenge for a truly meaningful human-computer conversation (which the human cannot distinguish from a real human-human conversation) - ever happen?
The Future - 2
•
Will computer hardware performance continue to double (Moore’s Law every 18 months http://en.wikipedia.org/wiki/Moore's_law ), which has been the case in recent history? Although IT is arguably an industry, where truly worthwhile software innovation, seems to lag considerably behind hardware improvements…
The Future - 3
• •
Although staggering improvements have been made in:
–
computer performance ,
–
data storage capacity and
–
communication speeds ; … in other areas (such as common sense, human emotion and artificial intelligence), arguably much less progress has been made in the past fifty years?
‘Windows 7’ - 1
•
Microsoft Windows 7
–
Is an operating system (used to control a PC and run software)
– – –
released in 2009 now regarded as stable replaced
Windows Vista
(perhaps less stable…)
•
Windows 7
is available in six versions.
In order of complexity and price, these are: [LOW] 1) Starter, 2) Home Basic, 3) Home Premium, 4) Professional, 5) Enterprise and 6) Ultimate [HIGH ].
The current undiscounted price of Ultimate is $320.
NOTE: The latest Microsoft operating system -
Windows 10
- is just being released.
‘Windows 7’ - 2
•
Windows 7 – some improved features are :
– – – – – – –

Areas Not Covered - 1
For those who like their fun to be more physical than with traditional computer games:
–
Wii technology provides Skiing without the unpleasantness of falling into snow, or boxing with no need to visit A&E afterwards ( http://www.nintendo.co.uk/NOE/en_GB/games/wii_games_1959.html
).
Hundreds of games are available, but the experience remains virtual – so arguably, never as good as the real thing .
–
I-phones : costing about £500 ( http://www.vodafone.co.uk/brands/iphone/?WT.srch=1&cid=ppc-goo cbu-c89-22784-br ) – enables email, internet access, phone calls, text writing, with built-in camera.
•
A variety of allow you to unwind after a stressful day.
–
Some are computer-based games free and come pre-installed with the operating system (such as Solitaire); are available, to
–
while others must be bought separately, such as Chess or Bridge (which can be played online – www.ebu.co.uk
).
Areas Not Covered - 2
•
Hand-held book readers such as Kindle (a trade name) and various others (from £89) http://www.amazon.co.uk/dp/B0051QVF7A/?tag=googhydr 21&hvadid=14098327796&ref=pd_sl_6mxs193w5_e
• •
Alas (or a coincidence?) - each competing manufacturer has access to only a small part of the book market, with their data held in differing and incompatible formats (like past word processors, video recorders, etc).
– – –
Educational software can be bought for your PC.
Various packages enable learning a foreign language (no substitute for working abroad for six months).
E.g. ‘LinguaTeach for Windows’ (by Akore).
Improve your typing skills; try ‘Mavis Beacon Typing Aid’.
Many others exist, such as (Boots’) or CAD (Computer Aided Design) software, widely used in Engineering .
Store Design software, Tom-Tom Satellite technologies - navigate from A->B on car journeys with a fair degree of accuracy.

Impact on Film/Media : digital cameras now widely replace the need for traditional film, greatly reducing the cost of producing images (which can quickly be sent across the globe) Narration – you can now highlight some text in Microsoft Word, and then hear it read out (played through speakers attached to your computer). Server farms http://en.wikipedia.org/wiki/Server_farm http://en.wikipedia.org/wiki/Myrinet - these can have over 100,000 servers, are well guarded, with their own power supplies, and are in isolated areas.
Using Computers Cheaply - 1
•
Use someone else’s computer – a friend, relative, neighbour perhaps?
UK libraries allow 1-2 hours free PC usage per day.
Long Eaton : Connexions have PCs for job search.
Community House has one PC for coursework and job searching (provision across the UK varies).
•
Poor people, living alone on basic state pensions: Should broadband access be free for those aged over 75, as for TV licenses? Could this group be helped with phone rental cost? (Special low-usage deals, or re-introduce party [shared] lines?)
•
Use printers sparingly!
Printers wear out quickly, and paper and ink can become expensive.
Using Computers Cheaply - 2
• –
Provide free high quality training as trained people are more productive
• –
Provide free high quality computer support, by phone, email or at a local drop-in centre as new users of computers can rapidly become disillusioned, after just a few minor set-backs
Issues with the Storm Worm
• – – –
This worm (it is just one example of many worms, in recent years) shows: the vulnerability of IT the later associated repair costs ; and the lack of sincere/meaningful concern about the actions of IT criminals and their consequences.
(See p256 259 ‘Schneier on Security’ by Bruce Schneier)
Wired
•
According to
Wired
, 27/9/2007 Storm Worm has the following features:
– – – – – – –
- 1-50 million infections
– –
Mutates, patient – slow infection Split functionality: 1) spreader cells, 2) command and control cells & 3) receive order cells Small level of damage initially. What happens later?
It was written by the Russians – who else?
It is a Worm, Trojan horse and bot - all rolled into one It has multiple command centres The payload alters every 30 minutes The delivery mechanism alters frequently Email display line changes frequently
Further Notes
• • • •
Premium dialler Software that illegally connection to a premium rate phone line and charges you lots !
redirects your internet Virus Downloaded from the internet (or email attachments) Varied effects: can wipe your entire hard disk clean!
‘Trojans’ - viruses hidden in a file.
‘Worms’ - viruses designed to infect lots of files. Spyware/adware Installed on your computer, without your knowledge. (can download free software to remove adware?) Alternatives to eBay? What are bots (web site search crawlers)?
Spam/junk email & popups For advertising (you can buy software to stop them appearing). Phishing, Pharming, firewalls, filtering and blocking software .

•
Currently, dozens of isolated indigenous Indian Amazonian communities are being connected to the Internet .
Why?
– –
To revive their culture and Enable them to keep in contact with villages several days walk away.
