Ah Ha I have finally succeeded in getting her to stop talking, peace and quiet at last, yahooo.
Anyway i must go and have my cup of tea that i made over 1 hour ago (reheated of course) and fold the load of laundry that I got off the line when I got home as I have to hang out another load of laundry tomorrow morning that is in the washing machine tonight. I am sure that I am married to the washing machine first and my husband second, that or I am having an affair with the washing amchine as I seem to be spending more time with it than I am with my husband.

Peer to Peer Case Study
P2P as software / technical network
See ‘How the old Napster worked’
An Introduction to Peer-to-Peer Computing - David Barkai (Intel)
In my last subject titled “Managing the Digital Organisation”, I learned a little bit about P2P architecture and P2P payment systems. PayPal which is used by eBay as a form of cash transfer if the customer does not have a credit card.
My husband works for the Brisbane City Council and uses a P2P software package, where files are shared and accessed without having to go through a server, this makes his job easier and faster as he works from home but is part of a LAN (Local area network).
File sharing can be beneficial purse if a community of students studying the same subject wish to share research material. However one must ask whether file sharing is ethical or illegal.
Privacy is Good
The utube version -part one - the links on the page will lead to all other parts
Recently a sneak peak of the opening ceremony of the Beijing Olympic Games was leaked to the public. A uproar followed as the International Olympic Committee (IOC) says that the Olympic Games is free to all forms of media including the Internet. But the uproar was unwarranted as everyone still turned up in person to see it live. I personally think that the real thing is better than a copy especially when it comes to movies or books.
About 5 years ago a copy of one of Jamie Oliver’s cookbooks was emailed to me, I had a brief look at it online, but chose not to print it out and wait to purchase the real thing. There is nothing like reading a book for the first time, the smell of the paper and the feeling of accomplishment when you finally turn the last page.
Unfortunately in this day and age and the technological advancements that occur regularly, piracy will always be an issue, but if one uses there common sense and does not participate in any unethical or illegal activities, they are at least not taking money out of the pockets of the people who write or create such books or movies.

This goes hand in hand as users feel part of a community when they transfer information. However they must be aware of any copyright issues pertaining to the information they want to share with other users.
Napster was proven to be very popular as it generated 60 million visitors per month (I was not one of them), but was shut down due to copyright breaches. They now have a new site which is a pay-for music site.

Peer-to-Peer File Sharing Since Napster
Even though there is decrypting software available to decrypt DVD’s and CD’s of movies and music so that you may copy them. One has to ask themselves whether the risk of doing so is worth it.
Copyright laws are very clear and users who wish to download or share files do so at there own risk. You can pay the small fee and download a song you like knowing that you have not breached any copyright laws and that the law will not be chasing you for breach of copyright.

With file sharing you leave yourself wide open to viruses, worms and phishing emails. So protecting your computer with the latest antivirus software and using common sense with emails is essential.
Protecting your privacy should always be paramount as you do not know who is on the other end of the communication. Be vigilant and you should survive any attempted attack.
Socio-political considerations
http://www.janisian.com/article- internet_debacle.html
P2P file sharing will always be apart of the cyber society. Marketers need it so that entices you into purchasing their products by giving you something for free, then hitting you up to cough up the cash to purchase the entire product.
Since the way of the future is going more and more online, P2P will be more than just a place to download music etc. Big business might see the advantages and introduce it into their global intranet, if they have not done so already.
Ecologies
How might the metaphor of an ‘ecology’ impact on the way you think about, understand or use the Internet?
Ecology – the study of the interactive relationship between living things and their ENVIRONMENT (Collins internet-linked dictionary of Sociology).
After reading ‘Information Ecologies’ by Felix Stadler and ‘Towards an Information Ecology’ by Rafael Capurro, here is what I interrupt the metaphor of an ‘ecology’ when I use the Internet. Firstly an Internet ecology is the relationship and interactions between people and the online environment, in particular the Web.
I mostly use the Internet to do research, interact with fellow students and retrieve my university workload. So I think in information ecologies, the spotlight is not on technology, but on human activities that are served by technology.
An ecology responds to local environmental changes and local interventions. An ecology is a place that is scaled to individuals. In an ecology, we are not cogs in sweeping sociological processes. Instead, we are individuals with real relationships to other individuals. The scale of an ecology allows us to find individual points of leverage, ways into the system, and avenues of intervention.
What I will take away from NET11 is that, firstly the Internet is an ever evolving system and that changes can occur all the time. My research skills have increased due to the way that I interrupt the results I get from the type of keywords that I use. Therefore I am more aware of how my interaction with the Internet will determine what reaction I will get from it.
How are the concepts ‘information’ and ‘communication’ understood within the framework of an ‘information ecology’?
An information ecology is a complex system of parts and relationships. It exhibits diversity and experiences continual evolution. Different parts of an ecology coevolve, changing together according to the relationships in the system. Several keystone species necessary to the survival of the ecology are present. Information ecologies have a sense of locality.
An information ecology is marked by strong interrelationships and dependencies among its different parts. The parts of an information ecology may be as different from each other as the sand, sunlight, saltwater, and starfish of a marine ecology, but they are as closely bound together. Change in an ecology is systemic. When one element is changed, effects can be felt throughout the whole system. To get a mental image, imagine dropping a pebble into a pond and watching the ripple effect spread towards the edges of the pond.
Communication within a ecology depends on the type of information received. If a sender does not communicate that they would like a response, then they are unlikely to get a response. We as humans need to communicate; this is taught to us from birth, that if we want something we need to communicate it with verbal words otherwise we get nothing. The same is said for when we interact with technology, we must communicate what we want in order to get it.
Without communication there would be no information.
Why don’t we talk of a ‘communication ecology’?
As my last sentence in the previous question states “Without communication there would be no information”. Therefore communication falls under the banner of information as I see it anyway.
Different communication ecologies are constructed to achieve different goals. For example, when finding health information is the goal, a different set of communication preferences will be generated than when the goal is to figure out where to get the best buys or how to stay on top of the local community.
On the Internet these days, users have various forms in which they may communicate such as, email, chat, and forums to name a few. But with all types of communication on the Internet users must abide by netiquette rules. Online communication is fast and precise, but it has it pitfalls as well, like systems crashing, loss of data, and miscommunication due to the lack of visual body language.

AUTHOR: Dix, A, Finlay, J, Abowd, GD & Beal, R
INSTITUTION: Pearson, Upper Saddle River, N.J.
This book is also used as a textbook, but it also offers a wealth of resources, exercises and also one can click on each segment of each chapter. It looks at other emerging technologies but is firmly rooted in strong principles and models independent of the passing technologies of the day. It can be used for introductory or advanced courses on human-computer interaction, Interaction Design, Usability or Interactive Systems Design. It would also prove as an invaluable reference for professionals wishing to design usable computing devices. The site is easy to use and finding information within the book can be done with just a click of the mouse.
I found that clicking on the chapters icon, I could view what was in each chapter and pick and choose what I wanted to read. Each chapter effortlessly flows into the next building an understanding of human-computer interaction for the reader. As it can be used from introductory to advanced courses in human-computer interaction, interaction design, usability or interactive systems design, it is easy to understand and gave me a better understanding of the subject. Personally I think that this online book is balanced as it is written specifically as a textbook which has to be balanced so that the student can form their own opinion of the subject.
In terms of future use, if I was doing an IT degree than my annotated bibliography would be more beneficial for me to refer back to as I think that it gives a quick overview of what the site has on offer. But alas I am doing a BA of Accountancy and I do not think there is much use for this type of site in my future, but I am grateful that I now have a better understanding of the Internet, thanks to NET11.
From an external point of view, if I was reading my annotated bibliography and I was after more information regarding human-computer interaction, I would use the hyperlink to look at the site, being that it is written as a textbook makes it even easier for a novice to understand human-computer interaction and they would find it useful and of interest to them as a stepping stone towards more a more in depth look at human-computer interaction.
Module 4 completed, thank god. Now onto module 5 and then onto conquering the accounting world. lol.

Searching the Web
I used Google for this task as it is really all that I have been using for the past 1 1/2. My keywords were "human-computer interaction". I got 5,620,000 hits and the 1st hit was http://en.wikipedia.org/wiki/Human-computer_interaction.
Using Copernic I got 36 hits by using 9 search engines for "human-computer interaction".
The main differences were the number of hits of course, plus Google gave me better results with using all words on the first page. Copernic gave me more credible results, apart from the fact that some sites appeared on both Google and Copernic. Copernic gave me % campatibility which is ok if you take notice of those types of things. By using Copernic I can narrow the results by using less or more search engines.
Copernic as most of the results were from universities and they are more credible sites to use when writing academic papers. I think so anyway.
Below are the first 5 hits I got in Google.
Below are the first 5 hits I got in Copernic.
BOOLEAN SEARCHING TASK
Here are my results using Boolean techniques on Google.
human-computer interaction = 5,630,000 results.
"human-computer interaction" = 10,100,000 results.
human-computer -interaction = 964,000 results (NOT).
human OR computer interaction = 37,400,000 results.
human interaction = 24,700,000 results.
computer interaction = 24,300,000 results.
Using Google Scholar I got 31,000 results using the keywords human-computer interfaces. It gave me a lot of good books and sites with the number of citations for each result. The citations help me determine whether to look at the result or not.
Using UniSA library, limiting search to electronic resources, I got 141 entries. Monash University library gave me 1031 entries as I did not use any limits.
ORGANISING SEARCH INFORMATION TASK
I used a program called EndNote to capture the following information. I was first introduced to EndNote last year through one of my subjects (cannot remember which one), it allows you to input a in-text citation in a word document while at the same time it creates a full reference for the bibliography or reference list at the end of the document.
Here are my best 3 sources that I found relating to human-computer interaction.

Screen Shot/Summary/Blurb: Much has changed since the first edition of Human-Computer Interaction was published. Ubiquitous computing and rich sensor-filled environments are finding their way out of the laboratory, not just into movies but also into our workplaces and homes. The computer has broken out of its plastic and glass bounds providing us with networked societies where personal computing devices from mobile phones to smart cards fill our pockets and electronic devices surround us at home and work. The web too has grown from a largely academic network into the hub of business and everyday lives. As the distinctions between the physical and the digital, and between work and leisure start to break down, human-computer interaction is also changing radically.
The excitement of these changes is captured in this new edition, which also looks forward to other emerging technologies. However, the book is firmly rooted in strong principles and models independent of the passing technologies of the day: these foundations will be the means by which today's students will understand tomorrow's technology.
The third edition of Human-Computer Interaction can be used for introductory and advanced courses on HCI, Interaction Design, Usability or Interactive Systems Design. It will also prove an invaluable reference for professionals wishing to design usable computing devices.

Screen Shot/Summary/Blurb: The present study investigated the psychophysiological effects of positive and negative affective interventions in human–computer interaction during and after the interventions. Eighteen subjects were exposed to pre-programmed mouse delays in an interactive problem-solving task. Following the mouse delays three types of conditions were used: positive or negative interventions given via speech synthesizer, and no intervention. Facial electromyographic responses were recorded from the zygomaticus major and corrugator supercilii muscle sites. These muscles control smiling and frowning, respectively. Smiling activity was significantly higher during the positive than the other conditions. It was also significantly higher after the positive interventions than the no intervention condition. The frowning activity attenuated significantly more after the positive interventions than the no intervention condition. Following the positive interventions the users' problem solving performance was significantly better than after no intervention. In all, the results suggest that both types of affective intervention had beneficial effects over ignoring the user. The results suggest further that positive intervention may be especially useful.
EndNote is an easy to use program that can be accessed while using word through the toolbar at the top of the page. If you fill in every detail in EndNote you would have a very through reference in deed. It gives you many options to choose from about what type of reference you are recording e.g. journal article, magazine article or web page.
Evaluating the web task will be on the next post, so that must mean that I am nearly finished module 4 tasks, Yahoooo.

Conceptual Research & Reflection Project
Concept # 7: Netiquette
“Good communication practice on the Internet is not something one ‘learns’, but something one ‘practices’ so as to teach others, less familiar than yourself, how it is done” (Allen, n.d.).
Just like in real life, there is an informal set of guidelines for appropriate behaviour on the Internet which is called Network Etiquette, or commonly known as Netiquette. These guidelines need to be learnt just like in real life. They are an essential part of communication on the Internet, as in face to face communication one can see and read the other persons body language and via telephone can hear the audible tones that you can interpret as behaviour, but on the Internet one cannot hear or see the other persons body language, so interpreting the senders message becomes very difficult and miscommunication can be very common.
In 1995 Sally Hambridge created a document called the RFC 1855 Netiquette Guidelines which provided a minimum set of guidelines for Network Etiquette (netiquette) to help new users to become familiar with the Internet culture and the behaviour that is acceptable on the Internet. It was the product of the Responsible Use of the Network (RUN) Working Group of the Internet Engineering Task Force (IETF). Even though some of the guidelines are common sense others need to be learnt (Hambridge, 1995).
Netiquette put quite simply is about remembering that there is human on the other end of any transmission made on the Internet. It is a sad, sad day when one has to be told how to act via a computer when we are instilled with all of our manners from birth. As a society do we constantly need to be reminded of our manners? Apparently so; due to of all of the different netiquette rules that are out there.
Virginia Shea (1997), published her book titled ‘Netiquette’, in which she has covered all areas of electronic communication. Again her first core rule of netiquette is ‘Remember the human’, in which she reminds us that we were taught to “Do unto others as you'd have others do unto you. Imagine how you'd feel if you were in the other person's shoes. Stand up for yourself, but try not to hurt people's feelings” (Shea, 1997 p. 35). Even though this should be common sense, it is quite frightening how easy it is to forget that there is a human on the other end of the communication and that they have feelings like you.
In this day and age of increasing technology, where one could loose themselves in virtual lives etc, Netiquette plays a big part of how one portrays themselves to other users. No matter what material you look at in regards to netiquette, the first rule is always ‘Remember the human’. That in itself says a lot about our society in this technological age. Whether one like’s it or not, documents containing netiquette guidelines are here to stay, to remind us all of the behaviour that is acceptable on the Internet.

Evaluation:
This document would be extremely useful to new users or ‘newbie’s’ as they are called on the Internet. It offers a basic list of guidelines of what is acceptable behaviour on the Internet. It was created by the Responsible Use of the Network (RUN) Working Group of the Internet Engineering Task Force (IETF). Even though it talks about some legacy systems, and was last updated in October 1995, it is still applicable to today when using the World Wide Web (www). It is laid out very simply so that one can find the information easily and it is written in plain English with no technological talk to confuse new users.
Shea, V. (1997). Netiquette.
Evaluation:
Virginia Shea covers the usual basics of netiquette with the usual list of rules, some discussion of email, email style, discussion groups, and flames. It expands beyond that, however, to information retrieval, significant violations, corporate, home and school etiquette, and discussions of sexual relationships, privacy and copyright. It is one of the most complete books on netiquette and offers some common sense on the subject of netiquette. It is easy to read and understand as there is no complicated terminology that would confuse new users to the World Wide Web. Virginia Shea attended
Concept # 23: Human-Computer Interfaces
“The Internet lessens the recognition of difference between humans and computers because, at a distance, it is often feels similar to communicate and act on the Internet regardless of whether one is speaking with a human or a machine” (Allen, n.d.).
In one way or another humans have interacted with computers since the 1940s right through to today’s Internet. Over those years humans have gradually accepted artificial intelligence or machines that can think. Even today humans are trying to make a robot as human as possible, take for instance Asimo the humanoid robot made by Honda. It can replicate human actions but is still yet to achieve human emotion. Asimo is at the forefront of robotic technology and travels the world interacting with humans to display how far robotic technology has come and what the future of robotics will look like. Asimo’s newly developed intelligence technologies enables it to operate in an environment with people and other ASIMOs, which brings Honda one step closer to the development of a humanoid robot that can be put to practical use in a real world environment requiring coexistence with people. (Honda, 2007).
New users to the Internet can indirectly interact with other humans via social networking programs, such as facebook, msn, skype etc. They still have a core set of friends as the CBC news (2007) stated “while many users have hundreds or even thousands of acquaintances on their accounts, their core group of close friends is till unchanged at around five people”. Even though these relationships are impersonal compared to face-to-face relationships they at least allow a link which would otherwise be lost. Or are they creating friend collectors, a person who collects little-known acquaintances for the sake of having a large number of contacts on their profile.
Humans are accepting that they are interacting with computers in many different ways. Whether it is through online banking, or blogging and even email. Even when humans ring companies they are interacting with computers by the speech recognition software asking for our choices so that we as humans can interact with the companies’ data bases.
Web 2.0 is even more about the human-computer interaction as it allows users to create, cut and paste, drop and click information within web pages. New users are been overcome with the desire to create more and more blogs, you tube posts etc. as they become addicted to being able to modify data and create something that the whole world will see. The thought of having billions of people look at what you have created can be an addictive drug for new users. They feel that they must spend an enormous amount of time on the computer just in case they miss the next big thing. It can cause them being isolated from the rest of the human race and they could feel overwhelmed when they do have to interact with other humans instead of staying in their comfort zone of interacting with computers that do what they are told to do.
Companies such IBM are researching human-computer interaction and their work is concentrated around the behavioural, aesthetic, and value-sensitive aspects of the design of interactive systems (IBM, 2008). Thus allowing them to provide more avenues for humans and computer to interact with each other. Who knows how far this interaction between humans and computers will go in the future. Only time and the limits of ones imagination will tell.

Once could spend all day just looking at each article from the A-Z index, but for a new person who does not know exactly what they are looking for this could be a deterrent. The added advantage of having a job bank is novel and would only be beneficial to professionals.
Concept # 26 Privacy and Security
“The Internet is a profoundly ‘open’ system and advanced Internet users are cautious about either accepting or sending material from and to unknown sources and are careful in releasing information about themselves in any form. Conceptually, the Internet challenges us to take greater responsibility for the protection of privacy and security than perhaps we are used to when dealing with the media” (Allen, n.d.).
SECURITY
The Internet has enabled individuals across the world to become increasingly connected over the past decade (Adeyinka, 2008). Unfortunately with this connectivity so to does the issue regarding security and privacy on the Internet.
Some of the most common attack methods used is as follows:
Viruses – they are self replicating programs that infect and propagate through files (Adeyinka, 2008). Most computer viruses deliver a ‘payload’, which may be benign, or it may be highly destructive (Laudon & Laudon, 2007).
Hacking – a hacker is an individual who intends to gain unauthorised access into a computer system, they are highly skilled at finding and attacking weaknesses in the security protections employed by computer systems and web sites (Laudon & Laudon, 2007).
Worms – are independent computer programs that copy themselves from one computer to another over a network (Laudon & Laudon, 2007). Two main types of worms are mass-mailing worms, which spreads through e-mail, and network-aware worms (Adeyinka, 2008):
Trojans – are software programs that appear to be benign but then they do something unexpected. Trojans are not viruses but merely the way for a virus or malicious code to be introduced into a computer system (Laudon & Laudon, 2007).
Spoofing – is when hackers use a fake identity, appearing to use a trusted computer, and therefore are able to gain unauthorised access to other computers (Adeyinka, 2008).
Denial of Service – hackers flood a network server or web server with many thousands of false communications or requests for services to crash the network (Laudon & Laudon, 2007).
Even though the Code Red worm infected more than 250,000 systems in just 9 hours on 19 July 2001, the economic impact was $2.6 billion (Householder et al., 2002). The largest impact of security events is the time and resource requirements to deal with them.
PRIVACY
Privacy is something that we took for granted back in the good old days, but in this age of technology privacy is something that we need to protect. “It simply means that the subject of information should be able to control the information” (Adeyinka, 2008).
We can most safely use the Internet by learning as much as possible about two areas:
• What the risk of using the Internet are; and
• Tips on how to successfully protect yourself (Attaran & Van Laar, 1999).
Some of the tips for safeguarding your privacy online are:
• keep all personal information private.
• check companies’ online privacy policy.
• take steps to remove your personal information.
• guard your password (perhaps the most important of all).
• do not get attached to attachments.
• watch what you download.
• keep up-to-date.
• protect your family from inappropriate sites (Attaran & Van Laar, 1999).
The best solution is privacy through technology as technology is a big part of the everyday life of everyone around the world. “The objective must be to bring privacy to the Internet, and bring the Internet to everyday privacy policies” (Attaran & Van Laar, 1999).
Privacy on the Internet is the responsibility of the individual. One must be vigilant at all times when entering anything private information onto the world wide web, one must never completely trust technology with personal and sensitive information, as hackers are always trying to find weaknesses and when they do, they will exploit that weakness and could even steal your identity to fraudulently purchase goods and services, or even siphon money from your bank accounts.

With a national helpline that supports the website, one can keep up-to-date on what the government is doing to help families, libraries and children protect themselves online.
Concept # 1: Asynchronicity
“Asynchronous electronic communication is not the opposite of real-time, synchronous communication: rather it describes forms of communication that appear differently ‘located in time’ depending on the perspective of the sender and receiver” (Allen, n.d.).
Until I started NET11 I did not realise fully how much of the online world depended on asynchronous communication. Throughout my working career and home life, the computer and its varying forms of communication just seemed something that I took for granted and never questioned. I actually never even heard of the word ‘Asynchronous’ or “Synchronous’ before starting NET11.
For those who do not know what Asynchronous means, The Free Dictionary (n.d.) states that Asynchronous means “pertaining to a transmission technique that does not require a common clock between the communicating devices, timing signals are derived from special characters in the data stream itself”. Basically to put it a way that a newbie would be able to understand, is that asynchronous communication is the way that we are learning NET11 with the discussion board and the various other forms of communication that we have had to do for this subject, for example forums.
Learning online can also be a blend of synchronous and asynchronous communication. However asynchronous communication allows the student to check in and check out on their own time (Kerim Friedman, 2007). Asynchronous discussion forums are often used to provide the learner with assistance, support and the social structures more readily available in the face-to-face environment (Sheard, 2004). Using asynchronous communication like discussion groups allows one to either join in or sit back and be a spectator.
Asynchronous communication has allowed foreign students the ability to study outside of their country without leaving the country itself. For this reason alone asynchronous communication plays an integral part in the distance learning experience. Throughout my studies with
E-mail is another form of asynchronous communication as there is no need to synchronize timing or worry about waking the other party up, and there is no cross-Atlantic time zones (Wozniak, 2004). Some people think that e-mail is a form of synchronous communication as they receive a response to the e-mail they sent immediately, but it is still classified as asynchronous communication as e-mail does not rely on a synchronized clock to perform its job. We must also remember that the receiver of our e-mail may have received hundreds of other e-mails apart form the one that we just sent, so if we want our e-mail to stand out and get immediate attention, then we have to give it some form of importance to the receiver by placing in its subject field ‘important’ or some other highlight.
The business sector can take advantage of asynchronous communication. Telstra is such an example by the customer being able to hear the whole top 40 whilst they are on hold. Being able to read frequently asked questions is an advantage to the customer as well, because they do not need to speak to representative face-to-face, and can seek out a solution to their problem at their own leisure or if they cannot find a solution they can contact the help centre for immediate help.

Evaluation:
Golberg gives a brief explanation of what synchronous and asynchronous communication are as well as pointing out the advantages in teaching and learning about asynchronous communication like email and bulletin boards.
He comments on how asynchronous communication tools remove both the geographical and temporal barriers. He comments on how the removal of the temporal barrier has enabled people to consider the discussion they are part of a little more carefully.
As an educator himself he stated that he may be a bit biased as he only uses asynchronous tools in his electronic course offerings. The article is easy to read and gives a fairly balanced argument.

Evaluation:
This website is all about connecting teachers and students with online resources, virtual communications etc. The website is organized well and gives you the basics of online training through its workshop, which is designed for instructional designers, faculty members, and other educators interested in developing online courses for high school through to college level.
Online learning is becoming popular due to the fact that each student and teacher has different learning styles and learning online caters for all of them, whether it is synchronous communication like podcasts or asynchronous communication like bulletin boards. The resources page gives links to further information and virtual schools and libraries.

Module 4 - Task 1
I chose to download Copernic Agent Basic and WebCopier Pro.
Copernic Agent Basic was the only free version I could download. At first I thought that it was really excellent compared to the google search I have been using since January 2007. But after a few searches and some light reading on the discussion board I have found that Connotea is better for academic papers and I really love the one click feature and the library. Also CiteUlike is excellent because of all the different journals that you can access.
I can honestly say that I did not know or hear about meta data prior to this subject as all of my previous subjects were to do with maths, law, marketing and management. If all I take away from this subject is all of the different programs that our out there to help with my research skills than I will be one happy puppy.
Getting back to Copernic Agent (Basic). I found it fairly easy to get around and after a few attempts, I got the hang of the basic use of the program, but I will be using CiteUlike and Connotea as well in the future as the more searches you use the wider the field covered.
The next program that I downloaded was WebCopier Pro, as I thought that it would an interesting program to have a look at. Well I have to say that it took 9 minutes and 32 seconds to download the liblearn.osu.edu website and then I ls5 tutor file part that I really wanted to look at later was very hard to find and actually it was never downloaded in the first place. I was ectremely disappointed with this program and I thank god that I do not pay for my 3G internet connection so I do not have to worry about ever using this program again. I found this program to be confusing and if you do not know exactly where to look for the one part of the website that you really want to look at off line then you could waste alot of time just trying to look for it.
I think that I might try and download another program and see if I like it better, maybe the bookmarking program to help me organise my bookmarks better.
Anyway I feel I have conquered the first task and now onto the 2nd task and the next 2 concepts for the assignment.
