Mass media: How RSS aggregates ReSourceS

https://commons.wikimedia.org/wiki/File:Fotothek_df_roe-neg_0000873_002_Otto_Grotewohl,_die_%22Neue_Zeit%22_lesend.jpg

Old School

Before everything went online, teachers shared ideas and resources by meeting face-to-face at conferences and collegiate gatherings, or through an academy. Resources were in paper form (or papyrus) and good ideas took months and years to get distributed through a community.

Sharing depended on the good-will of good teachers.

New School

Enter the information age: digital resources are now shared quickly and easily, without the need for face-to-face interaction. Educational institutions and organisations promote and assist this distributive process with online resource directories.

NSW DET teachers have a wealth of digital resources to draw from, with corporate online directories such as TaLe, CLI, regional offices, and the VC Cafe.

However, the sheer quantity of resources makes keeping track of what's there, and when it's updated, difficult and time consuming. Teachers have to consciously return to these directories to check for new ideas and resources. It's a swarming mass of media. This is counter-intuitive to the digital age.

But, a technology which is good at searching, aggregating, and displaying update data is RSS.

How does RSS work? Watch:


Resource directory feeds

So here's the idea: each resource directory include an RSS feed. Teachers could then use an RSS reader to aggregate updates from multiple sources. There's no need to consider combining resource directories into a central corporate database, as each teacher could personalise their RSS reader to subscribe to, and aggregate feeds from, directories of interest.

More Than Directory Updates

News blog feeds

But RSS could and should be used for more than just resource directory updates.

School newsletters are a collection of news articles pulled together and printed at a specific time on a regular basis (usually weekly). Instead of publishing a group of articles once a week, the articles could be published individually as a news blog, and parents subscribing to the blog's RSS feed would be notified immediately via their reader when new items are posted. The blog would allow for feedback and comments on each item. This starts the conversation that many schools want with their parents and community stakeholders.

The idea: schools stop desktop publishing newsletters as a collection of articles. Instead, blog these as individual items. blogED already has RSS enabled, so if the school news blog was Public, the school community could subscribe to that blog's RSS feed through their RSS reader and see (and comment on) the latest happenings and successes of the school.

Corporate RSS reader

But wait, there's more ...

With a corporate authenticated RSS reader as part of DET Portal access, school staff could aggregate feeds from several closed corporate sites and resource directories. If the sites enabled personalised search feeds, staff wouldn't need to regularly check for new resource items, as the RSS feed would display the latest updates for that authenticated user search. Inbuilt search services returned as RSS feeds would help navigate the mass of resource media.

Group blog feeds

With an authenticated RSS reader, blogs could be created for groups of staff.

For example, a school staff blog could allow all staff at a campus to access a history of meeting minutes, and an RSS feed would enable them to see and read the latest approved entries. Adding new staff members to the group would instantly provide them with access to a searchable history of entries.

Further, a cross-site staff group (e.g. TAS staff within a Community of Schools), could use blog/RSS to coordinate information and share resources. This would prevent the need for emailing Word or PDF files to lists of individuals. Members could be added to and removed from the blog, and all authenticated users could reference the blog as a searchable archive.

This could also be used for such regular internal sharing as student Daily Notices (Public blog) and upcoming staff meeting agenda items (Private blog). The number of blogs would not matter, as an RSS reader would aggregate all entries from a variety of RSS feeds for that particular authenticated user (staff or student).

Nutshell


  1. Corporate sharing sites and resource directories include RSS feeds (customisable to return user searches)
  2. Schools implement their newsletter as a Public news blog (with staff authors and principal delegated approvers)
  3. DET Portal introduce an authenticated RSS reader
  4. Staff trained to understand the value of RSS over email for distributing content and resources to groups

Sharing still depends on the good-will of good teachers, but now it's much easier to share masses of media with blogs and RSS.

What do you think? Too hard to implement technically? (No) Too hard to implement organisationally? (Maybe)

Giving the World Game Back to the World

Or: Democratising Football

http://www.fotopedia.com/items/flickr-2459274872
I'm not a football club owner. Not even a manager. I was once a high school football player. So the following comments are from an IT point of view; I have no experience running a football club or much else for that matter.

Recently Liverpool FC hasn't been playing too well, and usually mangement is to blame. In this particular case it's ownership ... a big legal battle abrews.

This raised some questions in my mind:
  • what is ownership?
  • how is it registered / controlled / enforced?
  • how can a suburb 'own' a football club?

Thinking about the last question I had an idea: put the ownership in the hands of the fans ... all of them ... millions ... around the world.

How?

InputsProcessesOutputs
money
  1. acquire cash
  2. make offer to buy
  3. if offer accepted then purchase and manage
ownership and management of Liverpool FC


STEP 1:

This could be tricky, especially for a new business paradigm. For a football club with such a large and enthusiastic fan base it seems obvious to ask the fans to buy in and control their own club. But why would they trust me to take their money and do the right thing. Escrow. Who would be the trusted independent third party?

  • Probably a national bank - keen to store money, and probably in for a cut of fees
  • escrow.com
  • FIFA

So, arrange a multi-million dollar escrow account. Advertise and get contributions from fans - maybe $2 each for an owner share and voting rights. One possible problem is a conglomerate purchasing a large slice of shares and taking control of the club - but how is that different from the current situation?

A website can link escrow funds to usernames, showing contributions raised and a countdown clock until offer will be made. The website could be used to blog ongoing issues and developments, and direct interested contributors to the escrow arrangement.

STEP 2:

Take the escrow money and offer to purchase the club. (How complicated can it be?) What UK foreign ownership laws apply? Probably need a business manager and some lawyers happening here.

STEP 3:

If offer is not accepted one of two things can happen:

  • all escrow funds can be returned to contributors
  • escrow can be extended, contributors can confirm their offer or retrieve their funds; more funds can be contributed before next offer is made

The choice of action could be left in the hands of the contributors using online polling.

If offer is accepted take the escrow funds and purchase the club - more lawyers?

Now the fun begins - escrow contributors become share owners, and can partake in management decisions via online polling. Choice of managers, players, venue construction, whatever it is that FC owners do. All in the hands of the fans - they can select and prioritise issues online. Management fees would probably apply to execute share owner decisions.

Once the club is back in the black, profits could be returned to the share owners in a manner of their personal choice.

Advantages:

Fans become share owners; they can influence the direction of their beloved club, and maybe make some money.

Disadvantages:

Would take a bit of trust and a lot of money to setup; and requrie a good management team to execute share owner decisions.

Let me know ...

  1. Could this work?
  2. Would you buy into a club?
  3. Should FIFA want to manage such a system, and give the world game back to the world?

Don't Blink

https://secure.flickr.com/photos/andresrueda/3027534098/in/set-72157622613750829/
Listening to Security Now 263 this week Steve Gibson of GRC discussed Blink, a 'new' form of contactless smart credit card technology. Although this has been around since 2005, it's probably only becoming more common now, and hence a major security issue, as current cards expire and are replaced.

Steve described it as "the dumbest thing I've ever heard of in my life. I'm not kidding."

Basically it's an RFID on your credit card so you can pass your card close to an in-store RFID scanner to make a purchase, instead of having to go to the inconvenience of manually 'swiping' and then having to pick up a pen and physically touch a piece of paper. 'It makes purchasing so much easier!'

Of course, this was developed prior to the current financial crisis, so marketers might not be so keen to tell people to go buy everything on credit.

A security concern that Steve discusses is the possibility of blink skimmers, a 'bad guy' walking around through shopping malls, train stations, and other crowded public areas with a skimming device, getting within inches of your wallet and skimming $25 from your blink credit card in seconds. The skimmer would leave a transaction trail, but could use offshore credit accounts to mask the trail, and hide in a foreign jurisdiction (maybe Nigeria!).

Alternatively, the skimmer might seek to not leave a $25 transaction trail, but instead steal the identity of the card itself, thus leading to credit card fraud on a grander scale. Chase bank state that 3DES symmetric encryption is used during the RFID negotiation and transaction. All you need is the shared key ... a good hacker should be able to determine that key using a bot-net in a couple of years. How long will these cards be around? Can they dynamically change keys?

So, if you get an RFID on your next credit card / passport / library card, what would you do?
