CitySpace 2.0

It is important to recognize that the emergence of the Web 2.0 is not a technological revolution, it is a social revolution, it is about how we use and perceive the Web. "Here's my take on it: Web 2.0 is an attitude not a technology. It's about enabling and encouraging participation through open applications and services. By open I mean technically open with appropriate APIs but also, more importantly, socially open, with rights granted to use the content in new and exciting contexts" (Downes, 2008)
As mentioned above CitySpace already has the necessary technology to shift from one-to-many approach to many-to-many, i.e. shift from Web 1.0 to Web 2.0. Lecturers and other staff have already great tools to create content. These tools and many other tools should be available to students.The Figure 1 illustrates the concept of integration of Web 2.0 applications to CitySpace. Potential developments that could be implemented into or used in parallel with current CitySpace system to improve and encourage creativity and sharing through collaboration and participation include:
UNIVERSAL ACCESS
Every year students create invaluable information through the discussion boards. By making this information accessible through discussion board search engine will be beneficial to new students. Adding to this concept, CitySpace is pre-customised based on student’s chosen course, hence the student can only see the content only for the relevant undertaken modules. Making any course material available to any student, and let the student choose and pick which course modules to follow. This would encourage students to take up on extra curriculum modules and self-study. Due to the nature of the content database, City University board should authorise the contents allowed to universal access.
FILE SHARING
Creating a “student bucket” for file-sharing where one can find: past exams with relevant discussion and sample answers, lecture slides and notes with relevant documents, audio and/or video recordings of past courses. To mention, but few: Slideshare.net – website where users can upload, view and share presentations and YouTube EDU – videos and channels from YouTube university and college partners.
PROFILING
Students (also staff) can create a public profile (Facebook, MySpace, Linkedin, etc) to give brief background information. This could also be made public outside university, making it available to future potential employers who could directly contact particular students if they are of any interest (employers might be interested in projects any particular student involved).
BLOG
UK scholars are slowly but surely heading into the blogosphere (Corbyn, 2008). Blogging (LiveJournal, Blogger.com, WordPress.com, xanga.com etc) is a powerful teaching/learning tool which lets anyone to publish website and create content with ease. Lecturers could create blogs of interest for students to comment on. Unlike current discussion boards these blogs would be available to view and comment upon for any student.
TWITTER
Yet another powerful social networking tool entering Higher Education is Twitter. Twitter can be used as a communications tool for collaborating researchers; As a way to get students to focus in a concise (140 words) way on a topic; and as a way for conference attendees/students to discuss topics on the spot, live, again in a concise manner (ELI,2007).
Twitter application could be implemented in the system for the lecturers so the students will “follow” to stay up to date with the lecturer, similar to Announcements on the current CitySpace. But this feature is useful as lecturers can update their status from their mobile phones. E.g. the change of lecture room or the lecturer is simply a little late, reminder of any changes in submission dates of coursework or change in exam dates.
DISSEMINATION TOOLBAR
Integration of dissemination toolbar into CitySpace 2.0 will make it possible to share chosen content with the community easily. Below, the Figure 2 displays the concept, e.g. Lecturer can upload new material to CitySpace and can immediately twitter about it to students. If students find this material interesting they can share it on social networking sites like Facebook or at social bookmarking sites like Digg or StumpleUpon, and so on.
As the social software applications open to all, some of the content published on CitySpace might require an authorised access only. This will ensure the content shared only amongst registered university community.Figure 2: Integration of Social Networking links to CitySpace
WIKI
The most popular wiki is collaborative online encyclopaedia, the Wikipedia. Simply, Wiki is a website or a collection of websites on a particular topic which can be created and edited by anyone. It is a website that is constantly “under construction”. Providers of wikis: Wikispaces, Seedwiki, PBWiki, WikiCities, Schtuff, Riters.com, etc.
Currently, once students submit their work for marking it is stored in a database with no future access to other potentially interested parties. It is a creative content that could benefit other students or any other web user if the work is published through wiki pages. It could eventually evolve into a rich content website by constant edition and collaboration.
Wikis can be useful to create e-portfolios. Unlike chorological blogs, wikis are organised by content. Depending on the importance of timeline the decision can be made which tool to use to create e-portfolio. (University of Delaware, 2008)
As some e-portfolios considered individual security issues, such as intruder editing others work, could be solved by the use of wikis internally within the university system to control over access to edit the website.
RSS
Sheer number of available social networking tools is overwhelming for anyone to follow without the use of RSS feeds. RSS – “Really Simple Syndication” or “Rich Site Summary” is a simple yet powerful tool that saves time visiting websites of interest by retrieving latest content from websites. Similar tool to web-based aggregator Google Reader could be added to CitySpace which would enable users to retrieve content from multiple website into one through RSS and/or Atom.
To sum up some but few mentioned potentials of Web 2.0 applications which could be used to improve educational process, it needs to be stressed that Web 2.0 is an attitude not a technology (Davis, 2005). Students are already using most of the tools and it is time for Education Systems to use those tools through changing attitude towards Web 2.0 way of teaching. This could be achieved by making relevant social software available through CitySpace system to lectures as well as students. Figure 3 illustrates the changeover needed to achieve this goal.

Home by Yann Arthus-Bertrand

Home is free 2009 documentary by Yann Arthus-Bertrand. It is made up of aerial shots of various places around the world. Strongly recommend to watch the movie, click here to watch. I especially recommend watching the movie to ignorant-pessimistic-skeptics for the sake of HD quality of beautiful aerial shots.
Here are some stats from the movie.

20% of the world’s population consumes 80% of its resources.
The world spends 12 times more on military expenditures than on aid to developing countries.
5,000 people a day die because of dirty drinking water.
1 billion people have no access to safe drinking water.
Nearly 1 billion people are going hungry.
Over 50% of grain traded around the world is used for animal feed or bio fuels.
40% of arable land has suffered long-term damage.
Every year, 13 millions hectares of forest disappear.
One mammal in 4, one bird in 8, one amphibian in 3 is threatened with extinction.
Species are dying out at a rhythm 1,000 times faster than the natural rate.
Three quarters of fishing grounds are exhausted, depleted or in dangerous decline.
The average temperature of the last 15 years has been the highest ever recorded.
The ice cap is 40% thinner than 40 years ago.
There may be at least 200 million climate refugees by 2050.

It’s up to us to write what happens next
Together!

What is Мой мир?

I have been using it for a long time to keep in touch with my friends from ex-USSR countries. Мой мир is a part of Mail.ru – the largest free e-mail service owned by Runet since 2001, but it was launched in 1997 by Port.ru. In 2005, the number of users reached 30 million, and 25 million emails were sent every day.

“Мой мир — is a place where finally all old friends could be brought together, and where many new ones found. Apart from this, you will stay up do date and keep in touch with them, by watching their photos and videos, read their blogs, answering their questions and leave notes on their guestbook, etc” – this is how it is defined at Мой мир homepage. Basically, it is a Russian version of Facebook.

The feature I have recently discovered is you can listen to any music of your choice any time for free with no limitations, provided you are registered and signed in. You can just search for the songs, and result will show a list of all matching songs uploaded by users with a play/pause button on the side. Click play and it will play continuously one song after another.

Here is an example. I searched for “Black Eyed Peas”, the result 816 files found including currently number one hit song on BBC Radio 1’s Official Singles Chart Show – ‘Boob Boom Pow’.
Amazing! No need to download or pay for music anymore. I wonder how they deal with Copyrights.

WolframAlfa is my friend

It has been a long two weeks with exhausting exam revisions, hopeless attempts to memorise every slide of lectures, every book and every note. This again proved Student Syndrome Effect. Whole term one does nothing until the deadline is close, and then tries to cram everything in ever shrinking temporary memory with enough lifecycle to get through the exams.

Anyway, so far three of exams are over, one to go. During which WolframAlfa finally was launched, Google came up with squared and was making waves, and now Microsoft is trying to join the battle with Bing.com, while hyped up Swine Flu is killing everyone and 47 million year old supposedly our ancestor monkey was re-re-re-discovered.

Back to Bing.com, not impressed. This blog with rather clever heading 'Bing? Insert "or" after B' says it all. The only useful and unique feature is the video search, where video playback activates on mouse roll-over, which eliminates the need to go the original website to watch the video.

WolframAlfa is in totally different level, if you ask it (him/her?) “
Who are you?” it will respond “I am a computational knowledge engine.” This is the feature I am looking forward to see improve. For question “Are you clever?” it responds, modestly, “I am capable of universal computation; that I can say.”


The point is, eventually, this search engine will be able to interpret human with better AI and then we will say “WolframAlfa is my friend.”, unless Google does not fight back, that is.

After Databases exam

It is such a relief...but still cannot shift away the SQL queries from my head, need a holiday!

SELECT vacation, location
FROM world
WHERE sky LIKE '%blue%'
AND beach NOT IN ('England')
AND exams='over'
AND balance NOT NULL
