On-Line Music

If you're new to the world of getting music on-line rather than buying it on CD, listen to this podcast, which describes the current state of play with on-line music, both for purchase and free.



Download MP3 File

Broadly, there are two ways to listen to on-line music
  1. Acquisition: download audio files and then listen to them
  2. Access: stream audio from the "cloud"
The trend appears to be moving from the traditional ownership (acquisition) model to access model.

Are You the Weakest Link?

Despite all the high-profile stories of viruses, scams and online security problems, technology really has improved our online security. But has it made our online lives safer? Maybe not, because now people are the weakest link in the security chain.



MP3 File

What's the big deal?

In spite of various technological security measures (anti-spam/virus/phishing) the ultimate security software is your own brain.

Here's a humorous take on this concept:



Some references:
Why is phishing still so popular?
  • It works!
  • Technology is getting smarter, so scammers have to resort to human frailties.
  • Things like Twitter and Facebook have made things worse: Many Facebook apps require you to give them access to your data, and Twitter tools often require access to your Twitter account. This has made some people far less careful than they should be with security and privacy.
  • URL shortening services don't help, for two reasons: (a) they mask the true URL, so you can't guess if a link is safe to follow; (b) they might lull some into a false sense of security - e.g. people see "bit.ly" and assume it's safe because it has been in the past.

So how should you protect yourself?

  • Don't let your guard down! It's as important as ever to be vigilant, careful and just use common sense.
  • Use protection but don't allow it to lull you into a false sense of security
  • Don't sweat the small stuff - but it's not all small stuff. Be more alert when there's a risk of giving out confidential information (e.g. online banking, unusual e-mails from your boss supposedly asking you to send her Top Secret documents), and relax when there's a lower risk (e.g. your spouse asking you to get milk on the way home).
  • Don't get scared off. Immerse yourself more - not less - in the Internet culture, so it becomes familiar to you. You're safer in your home town in familiar surroundings than as a naive tourist wandering through a strange city.

The Internet Road Warrior

How easy is it to do "business as usual" in today's connected world? Gihan put this to the test last month, and has just returned from a month in Prague, which was a combination of work and pleasure ("weisure", as New York University sociologist Dalton Conley calls it, or "furking" (combining fun and working), as Kirsty Spraggon calls it). In this podcast, Chris interviews Gihan about his experiences using the Internet for this purpose.


MP3 File

Broadly, let's use the metaphor of taking a trip. It has three broad parts: How you get on the road; what you take with you; and what you do when you arrive.

Get (metaphor for Internet access)

In general, Internet access in Europe is easy and fast compared with Australia (and in Venice, it will soon be free to residents). In Prague, wireless hotspots are widely available, though of course you have to be aware of security issues when using public access points.

Other access:
  • Use Skype for free computer-to-computer phone calls, and for cheap long-distance calls
  • Get a SkypeIn phone number for incoming calls
  • Get a virtual fax number with mbox.com.au - your faxes are delivered to you by e-mail
Take (metaphor for essentials)

Phrase book (metaphor for all the language things):
  • Be aware of differences in keyboard layouts e.g. finding the "@" key on an Italian keyboard!
  • Various Web sites (Google, Bing, Facebook, Blogger) detect your location based on IP address, and default to the local (Czech) version
  • Most informational Czech Web sites have English (and German) versions
  • If they don't, BabelFish can do translations for you
Money:Things to Do

Sightseeing:
  • Google Maps - invaluable for maps and directions
  • Tourist information Web sites
  • Coin-operated Internet kiosks in airports, info offices, etc.
  • Planning and booking side-trips can all be done on-line nowadays
Keeping in touch: Plan what level of information you share with each circle of people in your life - e.g.
  • Facebook for family and friends
  • A blog for business
  • An e-zine for subscribers
  • Twitter for anybody
Business meetings:
  • Use Skype for phone calls - as mentioned earlier
  • Use a webinar service like GoToWebinar.com for conference calls and presentations
  • Time zone issues - www.worldtimeserver.com has a handy meeting planner to show time zones in different countries

Web Search Upstarts

In our previous podcast we spoke of our disappointment that there is no significant competitor to Google's web-search engine. Contrast this with the situation in the late 90s when there was strong competition between search engines like Altavista, Lycos, Yahoo!, Ask Jeeves, HotBot, Northern Light, etc.

Recently, two new web-search engines have been launched, Wolfram's Alpha and Microsoft's Bing. Are they serious challengers to Google's dominance or will they follow other recently hyped upstarts like cuil into the dustbin of history?

Listen to the podcast here:



MP3 File

Wolfram|Alpha

Provided by Wolfram best known for their computational software Mathematica.

Introductory video from Wolfram.

Stephen Wolfram refers to it as a "computational knowledge engine" rather than a search engine.

It's built using Wolfram's Mathematica for performing calculations using reference data compiled from sources such as the CIA's World Fact Book and Wikipedia. As such, its "knowledge" is rather patchy and as a consequence a traditional search-engine, such as Google, is better at providing answers to the sorts of queries Alpha is meant for.

More:

Bing

Introductory video from Microsoft.

According to Microsoft, Bing is a "decision engine".
  • It categorises search results (you can click a category to refine your search)
  • It provides pop-up preview of each search result
  • Other search features: Health, News, Shopping, Travel, Images, Video, Maps (some of these aren't available outside the US).
Bing has got a lot of good press (e.g. Beware Google), but still seems very U.S.-centric. Many of the features touted in the introductory video and "Why Bing?" page, e.g. shopping, travel and local, don't appear to be available to Australia.

The New York Post (tabloid) reports that Bing has so worried Google that "co-founder Sergey Brin is so rattled by the launch of Microsoft's rival search engine that he has assembled a team of top engineers to work on urgent upgrades to his Web service". Most likely a sensationalised report of reality but if nothing else at least Bing is spurring innovation.

Conclusion

Are Alpha & Bing good tools? Yes

Are they going to knock Google off its perch? Unlikely

What should you do? As always, judge for yourselves. Keep on eye on these tools as they will continue to evolve and improve with time, and will continue to provide healthy competition for Google.

Technology Flops

PC Authority recently published a thought-provoking article: Top-10 Disappointing Technologies in which commentators Iain Thompson and Shaun Nichols discuss their top-ranked information technology failures.

We'll discuss these, omitting a couple (with which we're unfamiliar) and adding one of our own:


MP3 File

  • Virtual Reality: A technology that allows the user to interact with a computer simulation of a real or an imaginary world.
  • Alternative search engines: Google is the 600lb gorilla of web-search. Where's the competition?
  • Voice recognition (actually Speech recognition): The automatic conversion of spoken words into machine-readable input.
  • FireWire: A technology for connecting peripherals to computers, similar to USB.
  • Bluetooth: A wireless networking protocal for communicating over short distances - sometimes referred to as personal area networks.
  • Zune: Microsoft's line of portable media players.
  • OpenID: A standard that allows a user to log in to multiple services using a single digital identity.
  • Windows Vista: Microsoft's current PC operating system.

All A Twitter

Twitter is the latest Internet craze, but not everybody's convinced it's worthwhile - especially in your professional life. Join Gihan and Chris as they explain what it is, how it works and how to get the most out of it.



MP3 File

What is Twitter?

Compare Twitter with e-mail: Why don't we share our thoughts by e-mailing everybody in our address book?
  1. Not everybody wants it
  2. Fills up their in-box
  3. Messages are too long to read
  4. Gets mixed up with important e-mail
  5. Difficult to opt out
Twitter solves these problems:
  1. Only your followers get your tweets (messages)
  2. They only see what streams by at the time
  3. Messages have to be 140 characters maximum
  4. It operates as a separate channel from e-mail
  5. You must have their permission, and they get to opt out at any time
Where does Twitter/microblogging fit in the social networking landscape?
  • MySpace/Facebook: family and friends (small circle of people around you)
  • LinkedIn: professional network (larger circle, but still you get to choose)
  • Twitter: can be both (but very large circle - and you don't have control)
People on Twitter:
  • Gihan on Twitter
  • Chris on Twitter
  • Pollies: Kevin and Malcom actually get Twitter - Obama doesn't
  • Celebrities: Demi Moore does it better than her husband Ashton Kutcher; Oprah got 1,000,000 followers, but doesn't get it (tweets in ALL CAPS); Arj Barker gets it.
  • You're never too old to Tweet - Ivy Bean 104 years old
But does Kevin really get it? The Herald Sun reckons he's a boring twit, and Gihan reckons he's an arrogant twit with tweets like this:

How to Use Twitter

How to:

  • Deepen your domain: Follow smart people (use Twitter's search box or follow recommendations) and read what they say
  • Broaden your field: Follow others in your field, re-tweet, reply, DM, go "offline" to e-mail or their blogs or (gasp!) phone
  • Expand your network: Invite clients, prospects, e-zine readers and others to follow you; give them value (not promotional)
  • Share your thoughts: Link to your blog posts, link to other URLs you like, re-tweet good stuff, say wise stuff
The most important rule:

What To Do Next

Sign up, start following Gihan and Chris, follow the people they're following, then eventually start tweeting!

Remember: Twitter is like a magnifying glass, so use it to support what you do best - learning, collaborating, networking or sharing.

The National Broadband Network

The Australian government is committing $43bn in a public/private partnership to build over eight years a fibre-to-the-home (FTTH) broadband network, i.e. a national optical fibre network, superseding the existing copper (telephony) network.

It should deliver 100Mbps broadband to homes, which is a big improvement over the the current theoretical max. of 24Mbps (ADSL 2+) and average/median of 3 to 4Mbps (according to Speedtest.net and ZDnet). Currently Australia doesn't even rank in the world's top-20 for Internet access speeds.

Listen to the podcast here:


MP3 File

Some history:

  • Both parties made this an election promise
  • Telstra bid was withdrawn
  • No private tenders accepted
  • Govt. to go it alone
  • Govt. share to be sold off within 5 years of completion

Some criticism:

  • political grandstanding: Whitlamesque nation-building exercise
  • Would wireless be better?
  • Bundled with internet censorship legislation? (This would be a bad thing)
  • Too expensive
  • No private partners will be interested

As a result ...

It makes many of the technologies we've discussed in previous podcasts (more) possible:
  • Cloud Computing
  • High definition Internet TV
  • Video teleconferencing
  • E-health
  • Distance education
  • A key component if the government is serious about developing a thriving Digital Economy
  • Things we haven't even thought of yet: Build it and they will come...

Free is the New Business Model

Web 2.0 takes publishing out of the hands of a few and puts it in the hands of the many. Google is a free search engine; Wikipedia is a free encyclopedia; YouTube lets you be a movie producer; Blogger gives you your own newspaper column; iTunes gives you your own radio station; and Flickr lets you be a photographer. And all of these services are free. Is everything that's any good now free, and is everything that's free any good? More importantly, from a business perspective, will free destroy your business - or can you use it to boost your business?



MP3 File

Benefits
  • Free content gets them into your community
  • "Free" is a magic word in marketing
  • You must prove you're an expert before they visit your Web site
  • Make money through your content, not from your content
  • So much free stuff is available now anyway - if you can't beat them, join them
  • People will come to your Web site now not because of your advertising, but your reputation
  • New business models superseding the old (e.g. newspapers dying)
Examples
References
Conclusion

If you're a consumer:
  • Look for stuff that's free - it's probably available
  • Consider upgrading to the paid version - it might be worth it for what you get
  • No "free lunch" - sometimes there are hidden costs, from the innocuous (provide personal details, leading to spam) to the costly (sign up now, pay later)
If you're a provider:
  • Make more stuff free to build your reputation and get more traffic to your site
  • Find out who's offering the free version of what you're charging for - it might shock you!
  • Information is becoming a commodity, so figure out how to add services and experiences to commodities

Open Access

Although some government information is still clouded in secrecy, governments ARE increasingly using the Internet to give citizens more open access to some of their data.



MP3 File

This is a follow-up to our podcast on the "Digital Economy", in which we discussed initiatives by the Australian and US governments to tap into the Internet to help develop their economies.

One aspect of this is providing open access to public sector information, i.e. providing free access to information collected by government agencies.

Examples

Some agencies have been doing this for ages - it's part of their
mission.

The Bureau of Meteorology provides weather forecasts and historical climate data. Chris has a widget in his tool-bar that displays Perth's current weather conditions, five day forecast and radar map retrieved from the BOM server.

Transperth (WA public transport utility) provides bus, Train & Ferry timetables, fairs, route planners on their web-site. Also integrated into Google maps.

Fuelwatch gives us petrol prices in WA.

More recently...

The Australian Bureau of Statistics adopted the Creative Commons 2.5 license for its data sets.

German Federal and State agencies donated 350,000 pictures to Wikipedia under the CC3.0 attribution+share-alike license.

MIT announced all faculty publications would be made open access (usually copyright is signed over to journal publishers).

Caveats

An important consideration in the publication of [government] data sets, is respect for privacy and security. An article in Computer World found on-line government records the richest source of personal information (social security number, address, occupation, image of signature etc.)

Often the government's heart isn't really in it - it's more about political window-dressing, e.g www.GroceryChoice.gov.au

Conclusion

If information is power then more power to governments who open access to their public sector information.

The Wild Web - Regulating the Internet

Government regulators are fighting a losing battle to gain control of online content and activities. How do you give people the freedom to express themselves while still protecting the rights of others?

Cloud Computing

With more mobile Internet access, there are advantages to keep your software, services and data in the "cloud" - i.e. on the Internet - rather than on your own hard disk. But this also presents risks and challenges.

The Digital Economy - Are They Serious?

The Australian Government and the new USA White House administration have both launched initiatives claiming to get in touch with their citizens via the Internet. But are they serious, or is it just window dressing for political purposes? Gihan and Chris discuss the pros and cons of the two governments' approaches so far.

Internet Predictions for 2009

Microblogging, crowdsourcing and online gaming - just three of the ten fearless predictions Gihan Perera and Chris Pudney make for 2009.

Listen to the podcast here:


MP3 File

Gihan's 5 predictions:
  • Blogging will become more common, because blog reader software is more mature
  • There'll be even more free stuff, and businesses will have to monetize through advertising, subscriptions or premium services
  • Everything will accessible via your phone
  • There'll be more crowdsourcing and collaboration
  • We'll have tools to serve lots of social networks at once
Chris' 5 predictions:
  • Strong growth in (on-line) games industry.
  • On-line advertising revenues will fall: a consequence of the predicted economic downturn, and ad-blocking.
  • Everything will be in The Cloud (web-hosted software services), spurred by drive to reduce costs and improving reliability.
  • Continued strong growth in Internet population mainly from developing nations.
  • Social Networking web-sites will become more popular.
And we both think ... Australia won't censor the Internet! But we might get a face-saving watered-down version.

Will Australia Censor the Internet (even more)?

The Australian Government is considering a controversial proposal to (further) censor the Internet for Australian Internet users. It's controversial because it's unworkable, ineffective and likely to cause more problems than it solves. Find out more about the issue as Chris and Gihan discuss both the technology and the politics behind the proposal.

Think Local

Any time you use the Internet, you have to remember we live in an international community. Some Web sites cater for international users; others don't. In this podcast, Chris and Gihan talk about internationalisation (or should that be internationalization?) on the Internet, and what you have to know to enhance your on-line experience.
