Abrv: The Shortening

Old-school text-messaging led to the abbreviation of language. 4 eg u can read this :-)

But some common technology terminology is still spoken in long-form. And when mainstream media highlight a website, they sometimes use a lot of syllables. For example; telling folks to link to this website would sound like:
  • h-t-t-p-co-lon-for-ward-slash-for-ward-slash-dou-ble-u-dou-ble-u-dou-ble-u-dou-ble-u-dot-blog-ger-dot-com
29 syllables; most of them protocol; only 4 of them (14%) are site specific.

Proposal

So, I propose a verbal shortening for some common web words:
  • http = hittip
  • www = dubtrip
  • foward-slash = frash
Audibly this website then becomes:
  • hit-tip-co-lon-frash-frash-dub-trip-dot-blog-ger-dot-com
13 syllables; halving the spoken wordage.

Other tech terms could also be shortened:
  • back-slash = blash
  • hash-tag = tash
  • IPv4 = IP4 (we don't refer to Windows v8 or Mac iOS vX)
  • IPv6 = IP6
Every syllable counts! (Save time = save energy)

Thumbs Up

frash and blash are already listed in Urban Dictionary; but I've added these technology terms as alternate meanings. Feel free to give them thumbs up (no login required).

Virtual Reality vs Real Virtuality: The Virtual Visitor Information Centre

http://www.echonews.com.au/news/art-and-environment-captured-in-rainforest/1688343/
The Lismore Visitor Information Centre (VIC) recently revamped their indoor model rainforest walk into a vibrant, interactive display, featuring murals.

I'm calling this Real Virtuality (RV). Real in that it's a physical installation; Virtual in that it's emulating a rainforest. (Note: Wikipedia uses the term differently.)

To enjoy the RV experience though visitors need to visit the Visitor Information Centre. This implies the visitor is already physically in the area, and they have to take time out of their visit to find out what to do during their visit. Normally you would not expect the purpose of a visit to be checking out the local Visitor information Centre; rather to walk through a real rainforest.

Instead of spending $120,000 to refurbish an RV, let's consider how this could be used to develop a Virtual Reality (VR) experience. This could include:
  • Enriching Google Maps with local knowledge
  • Creating StreetView panoramas into the local rainforests
  • Adding web-mapping interactive content, such as historical or site-specific photos and local stories
This might've all been possible for less than $120,000, and encouraged an open-knowledge community-approach to tourism. Plus it could benefit the local population and students wherever they are, and possibly encourage them to access the real rainforest.

Advantages:

  1. Openness - encourage local community to contribute and update content
  2. Reachability - available to all visitors with an internet connection (including people in the VIC)
  3. Cost - low on-going hosting fees (depending on services used; need to consider cost of authorised content changing)
  4. Updatability - content can be easily modified

Disadvantages:

  1. Copyright and privacy issues (of uploaded panoramas)
  2. Limited viewing space (user-dependent mobile devices; but they can always ask for a real map at the VIC where large screen interactive displays are installed)

Maybe this could be a future direction. What would you want in a virtual Visitor Information Centre?

Change Management: The teacher becomes the student

http://www.fotopedia.com/items/flickr-2572841582
After teaching high school students about computer hardware and programming languages for 20 years I am now practicing what I preached!

This week I started working as a Technical Support Officer in the Administrative Systems team of Southern Cross University. I'm learning about managing system environments, modifying and applying upgrades to corporate software, and providing advice and operational support to clients for Corporate Services applications and other related systems.

Conceptually I understand what is happening, but learning the nitty-gritty details will take time. Fortunately, one of my tasks is to update and develop documentation, so I have time to delve into the details. And to put the theory from the classroom into practice is very exciting! A highlight was a guided tour by one of the Senior IT Admins into the corporate data-centre.

Leaving the high school system has meant a change of environment, and work practice. It has also meant moving from blogED to blogspot; I assume my DEC account will be disabled, and at end-of-year when blogED is archived I will be unable to access the content (and drafts).

Getting content into blogger was not as easy as I expected. Text, image, and video data was fine, but using tables with CSS had specific quirks, requiring some fine-tuning. And tracking down some of the original content for some posts took some time.

In future I'm considering how to incorporate an audio edition (podcast) to blog posts; just need a convenient way to implement RSS. Things will continue to change ...

Q: To BlogED or Not To BlogED

A: Since 28-Aug-2010 I've been blogging using the service developed by my employer.

I've written about the value of teachers and students using the blogED service to display their work and start conversations, and this has motivated some of my students, and created discussion about appropriate online comments and privacy concerns.

However, for my personal use I've decided to try other providers, and after considering wordpress, my ISP, and some other choices, I'm going with blogger, mainly because it links into Google+.

The catalyst for this change was that the blogED service archives all blogs during the December-January vacation, and unless I have prior written consent from my principal, I can't create or edit any posts.

When I emailed the IT helpdesk about this a senior support analyst advised why this was necessary:

The “No blog creation” option is business decision.   The reason is that during the summer holidays the student rollover process is executed to include the new year students. As the process was completed last week the provisioning for all staff/students/groups to blogED has commenced this week. Until this process is complete, however, the new students/groups won’t be available to the staff to add to blogs.

I understand there are also (legal) privacy issues, where school staff are not allowed to communicate with the students during this school holiday period. We have, however, escalated the issue for you.

Email 11-Jan-2012 9:51AM
name withheld as analyst did not respond to invitation to discuss this issue on corporate micro-blogging service

BlogED must be a complex machine, trying to authenticate staff and students and allow permission rights. So to avoid that hassle, I'll start using blogger.

I guess I'll also transfer old posts here and back-date them. Apologies that I won't be able to republish comments, but I might include them at the bottom of the posts.

blogED: Some Good, Some Bad, and Some Ugly



blogED is a blogging environment developed for NSW government school teachers and students. (You're reading one of the blogs right now!) It is a great concept, with some excellent features, but also some foibles, and some uglies.

Some Good

I fully support and recommend using Department sanctioned software. That way staff and students are familiar with the software and systems from site to site, and resources can be easily shared and centralised.

So as a blogging environment for sharing ideas with colleagues, teaching and learning in the classroom, and distributing information to parents and the community, blogED is a great concept.

One excellent aspect is that it links directly into student portal authentication, and students can easily be grouped to create class blogs, even across multiple sites (if you have a multi-site group). Authorisation is reserved for staff blog owners to check all posts and comments, and the owner of a site can be easily changed if staff move location.

Once a student is added as a blog author it's trivial for them to create a post and then have that authorised and published by their teacher. Then students can share and comment on each others work (and they can consider the copyright and privacy aspects of doing so).

Being able to insert multimedia is great, and these generally format well, and are easy to use.

Some Bad

One of the limitations of blogED is the look. There are currently only 4 themes to choose from, and customising the appearance of the blog for a student or class is not easy.

The graphic at the head of this blog incorporates an image, with a text overlay. I used colour-matching to merge the header graphic of this blog into the base-colour of one of the four themes, but matching it and aligning for the text overlay was not quick or easy.

Hopefully in blogED 2.0 there will be more simple themes, but maybe also some customisation tools to enable students (and staff) to edit the head/foot and, for power-users, modify CSS.

To insert images you can't link to them, you must upload them to blogED. I'm glad we must include copyright information, and attribute the appropriate source, but I don't understand why we must save a copy of it to the blogED server before it can be used. My best guess is so that the blog will continue to show the image, even if the source server is down.

Some Ugly

One of key concerns with blogED is that the formatting you see while writing is NOT the formatting of the published post. What You See Is NOT What You Get (WYSINWYG). That's ugly.

You have the option to preview your post, and you really have to, because while you are editing you don't know how it will look when published. Standard HTML tags like unordered-list are rendered correctly in the inline editor, but not when published. What the?



ABOVE: An unordered-list in the editor (click to enlarge). The editor shows correct indentation of the list, so that the bullet points stand-out.



ABOVE: An unordered-list when published.

There is no indentation and the bullet points to not cleanly separate from the main body of the text. I'm viewing this through Internet Explorer 8 on Windows 7 (using a DER device). (Maybe things appear correctly in Firefox or Chrome, but those browsers are not supported on the DER devices.)

The above picture also highlights the attribution notice displayed for all images. The image can be aligned to the right, but the notice remains at the position where the image was inserted in HTML. Also, HTML image alignment seems to break due to the the call of a javascript function (specifically addCopyrightInfoDivsAfterObject in https://www.det.nsw.edu.au/mediaLibrary/mediabrowser/copyright.js) which adds objects and code to the published post, but not within the editor. This breaks the formatting between the two views of the same code, and can lead to some unexpected and ugly results. (These methods of image alignment are deprecated, and should be upgraded to use styles.)

And inserting an uploaded image is awkward. The editor allows for resolution selection (the size of the published image), but the user is required to make multiple decisions to determine the best view of the image. I think this is incorporated into blogED for the image to be formatted (and desolved) at the server before transmission to the client. This would conserve bandwidth, but can be a headache for the posting author.

I generally post images as "large" and then use the Appearance tab to specify the resolution. Hyperlinking the image to itself then allows readers to enlarge the image:




If you highlight text, the space at the end of the text will also be highlighted, and adding a hyperlink will show the link dribbling off the end. (Notice the hyperlink between "dribbling" and "off the end"). So you need to ensure that the trailing space is not selected before creating the hyperlink.

Bullet-formatting, image uploading and insertion, and WYSINWYG ... all of this means spending twice as much time creating content as expected, half in writing, and half in quirky formatting. That's ugly.

As a case-in-point: the above images were inserted into the editor side-by-side.



Unfortunately, the inclusion of the copyright blurbs breaks that formatting. Possibly we're not expected to use alignment methods, but they are included as part of the editor.

Nutshell

I love the concept of blogED; an inhouse solution which generally works well, and integrates with departmental authorisation, copyright and privacy. The uglies are only publishing and formatting issues, but they could be the straw on the camels back which prevents some staff and students from sharing.

Maybe wordpress was not an option, but maybe it should be. A customised version to link into with the departments authorisation might be a good solution. Hopefully blogED 2.0 is in the works, and some of these deprecated and inconsistent formatting methods will be revamped.

  • If you're a blogED author, what tips and tricks do you use to format content?
  • If you're a blogED developer, and need a beta-tester ... :-)

Ideal Search: Don't Forget to ask "Why?"

http://www.abc.net.au/science/quiz/archive/smiller.htm
Ben Gomes (Google Fellow) posted a video on 28-Nov-2011 entitled: The evolution of search in six minutes.

In it Amit Singhal (Google Fellow) describes his ideal Google (from 5:30). He describes a search engine that returns answers to complex questions such as "what is the best time for me to sow seeds in India given that monsoon was early this year."

Amit doesn't provide a sample response, but it might be something like:

June-24

Providing the answer to a complex question needs to have the option "Why" or "Proof" or "References". If the question is misinterpreted, or the analysis is incorrect, or the response is in an unexpected format, Amit may lose a season of crop.

The sample response imparts knowledge, but it does not impart wisdom or understanding. An option to prove the answer, to question why it is so, to help people understand how that response was selected, might impart  both wisdom and understanding.

In Google's philosophy, they state core principles which guide their actions. Core principle 6 highlights: You can make money without doing evil.

  • Google money comes from ad hits. So here's the paradox. Amit wants to sow seeds. He asks Google (1 page hit). Google gives a response without proof. Amit plants and things grow. He trusts Google.
  • Next year the monsoon is early. Without understanding, Amit may choose to consult Google again (2 page hits). If he has understanding though he may wisely deduce the knowledge himself, which does not result in a use of Google, or the ads they display.

So is it in Google's interest to impart knowledge, but NOT impart wisdom. Is that "doing evil"? I think so. It reminded me of the filter bubble.

This paradox only arises as the complexity of the questions increases, and the interpretation and analysis of data and information frays.

And I think it is resolved by Google telling me the simple answer to a complex question, but then allowing me to choose "Why", or ask for "Proof". Something like:

June-24 Proof

That would increase knowledge, understanding, wisdom, and user confidence. And it might be "doing good".
