The Future of Flickr

internet, photography | Posted on January 7th, 2012 10 Comments »

It is no secret that I love the photo-sharing website Flickr.

I have had an account on Flickr since 2007 and have uploaded more than 3,100 photographs in that time that have been viewed by more than 107,000 people.

I have made many online friends as a result of Flickr and the website has been useful in attracting customers to my own photo website Photologium. I have always believed that Flickr is the best photo-sharing website and continue to believe this. But something disturbing has been settling in the back of my mind about Flickr for quite some time.

It’s all in the code…

internet | Posted on June 13th, 2011 No Comments »

Today I am proud to announce the launch of a brand new blog of mine. Entitled code.adonline, the brand new blog site aims to provide a specific focus on web design and coding matters.

I am a “hands-on” sort of web designer: All of the graphic design, the content and the coding (or implementation in the case of packages) is mine. Of course, I use a wide range of tools to design and build my websites and in 2011 it adds up to a massive body of work. In the process, I make many discoveries.

For quite some time, I have wanted an outlet where I could share coding workarounds and snippets for others to benefit from. I have also wanted an outlet to write specifically about some of the technical aspects of web design and the internet.

The Grapevine never felt like the right place to do this. Hence code.adonline has been created.

Rest assured that the Grapevine will remain exactly as it is: General in nature and aimed at a broad audience. I’ll continue to write engaging and thoroughly-researched articles for you to enjoy on the Grapevine and save the technical stuff for code.

If you’d like to read the first introductory article on code, go to http://code.adonline.id.au/welcome/ Your feedback would be most welcome, either on this blog or on code.adonline.

Enjoy!

Keeping eyes off your social media

internet | Posted on March 21st, 2011 2 Comments »

If you want to keep prying eyes away from monitoring your social media sessions, then you might like to spend a moment acquainting yourself with the secure versions of your favourite websites.

A few minutes updating your social media bookmarks could really give you some peace of mind.

Normally internet traffic is transmitted via HTTP or Hyper Text Transfer Protocol, which isn’t very secure at all. In fact, everything that you send between your PC and a website could theoretically be intercepted by a third party, which includes passwords and data. Whilst practically the chances of this are small, it does happen and you certainly wouldn’t want sensitive material being transmitted this way.

Thankfully, the answer to this problem is HTTPS, or Hyper Text Transfer Protocol Secure, which adds SSL/TSL encryption to HTTP. By using HTTPS, you can ensure that all data sent between your computer and a web server is encrypted, and therefore cannot be intercepted by third parties. The security comes from the fact that a person who managed to intercept the signal would only have gibberish to work with, so your data is safe.

Your bank and your email provider will use HTTPS to encrypt your data when you log on.

You can tell if a site is secure because the web address will start with https:// instead of the usual http:// and there will be a coloured panel in the address bar in Firefox and a padlock symbol in Internet Explorer (shown below).

Secure websites are issued with certificates from recognised authorities. I won’t detail how this works in this article, but suffice to say that a properly secured website will have a certificate issued to it. You should not trust HTTPS sites that lack a proper certificate. Your browser will alert you to such sites before they load.

If an HTTPS site combines both secure and non-secure components (a very bad practice) a broken padlock symbol will be displayed. You can use such a site at your own risk.

Of course it isn’t just third parties ‘somewhere in cyberspace’ that you might want to protect your private data from. In fact, it could be much closer to home.

Many employees (whether permitted or not) use social media at work. I am not going to discuss the rights or wrongs of such practices, but I suggest that if one is going to use social media at work,  they may want to consider whether they want their employer knowing what they searched for on Google, posted on Facebook, or discussed in Twitter.

Pros and Cons of HTTPS

Accessing websites via HTTPS effectively prevents your employer, IT department, school, university, or even your ISP from knowing what you searched-for and posted online. But beware, this comes with some significant qualifiers!

Google comes in an SSL version. If you search for a term – let’s say “widgets” – then your employer will be able to use network records to detect that you have been on Google, but not that you have searched for “widgets”. If you used normal Google, this information would be disclosed. However, as soon as you leave Google – let’s say you go to widgets.com – then your employer can see that you went to that site. So even if the boss can’t tell what you’re searching for, there might be other clues in your online behaviour that give it away

Additionally, IT departments have other tools to see what you might be doing online, such as random anonymous screen grabs. No amount of HTTPS will save you from an incriminating screen grab!

Finally, we’ve all heard about the famous cases of people criticising their employers on Facebook, only to be caught and then summarily sacked. Again, HTTPS won’t save you if you’ve made your boss, or his lackeys, your “contacts” on Facebook or you have posted a defamatory rant to Twitter where anyone can read it. So be sensible.

Social Media Using HTTPS

To assist you in keeping your private correspondence private, many social media websites (and a few other popular services) now offer HTTPS or SSL versions of their websites. Here’s a list of the most popular social media websites, and their secure addresses.

You might notice that HTTPS sites take slightly longer to load, but that’s because your secure connection is being made.

The future of bookshops

general, internet | Posted on February 17th, 2011 10 Comments »

Australia’s communications landscape is changing fast. What would have been unimaginable even a decade ago is now a reality; television network audience shares and profits are falling, the long-term viability of print newspapers is now in question and suddenly Australia’s two biggest book store chains have gone into voluntary administration.

I love books!

I have a large collection of books covering such varied topics as Australian politicians, history, architecture and travel  mixed in with tomes about plant physiology and molecular genetics. My personal and professional interests are co-mingled on a vast series of bookshelves. Whenever I want to check a fact, verify a claim, or just relax and read a story, my books are right there.

For that, I can thank the book shops (and let’s be fair, probably my education too). For myself, and millions of other Australians, looking through bookshops is an enjoyable task that introduces us all to new and  interesting titles. Yet apparently, the internet threatens the very survival of the bookshop as we know it.

For starters, let me say that I think talk of the ‘pending death of the bookshop’ is over-hyped. I simply don’t believe that bookshops will become redundant, although I realise that their market share (and perhaps commercial influence) will fall in time. There is much potential in the e-book, although there’s a lot lacking too. That said, the possible demise of REDGroup, which owns Angus & Robertson and Borders (in Australia only) is a very worrying development.

In Victoria, the books market seems to consist of Borders (which has the biggest range), Angus & Robertson (the biggest chain), Dymocks and Collins (two smaller chains) and a host of smaller, niche and specialist stores. There’s a gulf between the size of Borders and the smaller chains. Where Borders lacks in value, it compensates with range. And range is important.

Borders is very popular and on account of that, the company encourages a vast number of people to read. I firmly believe that reading, along with education, faith and public broadcasting are the key pathways to the development of an intellectual, enlightened and reasoned mind. I certainly don’t suggest that without Borders, society will be ruined. However, unlike most bookshops, Borders encourages dining and reading within their stores and so they effectively make books more accessible. That benefits us all.

The range of books I find at Borders is unmatched anywhere else. I cannot tell you how many books I have read because I saw them in Borders, where they weren’t stocked elsewhere.

I love reading about Australian political history. Aussie politics is admittedly not a topic that enjoys mainstream appeal. Whilst most bookshops would sell the popular volumes such as The Latham Diaries or Lazarus Rising (John Howard’s autobiography), they’re unlikely to sell The Long Slow Death of White Australia or Andrew Fisher: Prime Minister of Australia or Rudd’s Way. I know that these books are occasionally available elsewhere, but they’re much more difficult to locate and I know that I’d be very reluctant to buy them online without seeing them first.

The Australian book retailers often complain that internet booksellers are taking their market.

As the Australian dollar reaches parity with the United States dollar, there’s never been a better time to buy books online. Australia’s book industry is effectively protected behind a tariff wall, so books sold here are more expensive that those bought overseas. Because the Australian economy slowed (and hence discretionary spending fell) during the Global Financial Crisis, it’s no wonder that the book retailers may be ‘doing it tough’.

Yet the internet can never really replace bookshops for several important reasons: If it weren’t for bookshops, it would be much harder to know that certain titles even existed. People may discover that Amazon sells books much cheaper than Australian retail, but I suspect that most people buy books that they’ve already seen somewhere else, decided upon purchasing, then shopped online where the price is better. Bookshops provide customers with exposure.

The internet also won’t replace bookshops because browsing is much harder online. Think about how many times you’ve picked up a book that seemed so promising only to flick through its pages and discover otherwise. At least in such circumstances, you’ve not committed to purchasing the book.

There is some debate about whether e-books will simply make paper books obsolete. I suggest that they won’t, although I certainly see that for fiction (and newspapers or magazines) they may be better than the paper version. For non-fiction, I believe they’d make a poor substitute although I can see potential value even here (for instance, a plant physiology book that could incorporate a 3D model of a plant cell rather than a diagrammatic outline). I don’t think viewing detailed architectural plans or high-resolution images of an Australopithecus skull on a small screen would be much of a substitute for a high-gloss fold-out printed page.

For some, there is also the romantic notion of holding books, smelling the paper and feeling the texture of the page. Whilst that is a niche interest (similar to music buffs who insist on listening to vinyl or photographers who use film), I don’t see that as a mainstream concern.

Of course, in these changing times bookshops need to adjust and adapt. Perhaps like car manufacturers, television networks or hardware stores, there just isn’t as much room in the Australian market as there used to be for so many players.

If Borders and Angus & Robertson were to fail (and this is no certainty), it would be an unfortunate loss. Aside from the jobs directly lost, it would also likely hurt the Australian book publishing industry.

I have no doubt that like the newspaper and broadcasting industries, the book industry is entering a period of substantial change and possible consolidation. It will be fascinating to see what changes, both in a corporate and technological sense, emerge in the coming decade.

Whilst I firmly believe that e-books offer immense opportunities, I hope that I will always have the opportunity to browse real books in a real shop. After all, real books don’t need batteries, charging or firmware upgrades.

Syndicating my blog posts in Facebook

internet | Posted on January 26th, 2011 3 Comments »

As Web 2.0 matures, it is becoming more commonplace for different social media platforms to become integrated.

For instance, my Flickr account is linked with my Facebook account, so that as soon as I post an image on Flickr, it is automatically syndicated to my Facebook wall so that my Facebook contacts can see the image too. All of that happens and I don’t need to do a thing.

Linking accounts is a great way to generate traffic and make sharing easy.  Because social media sites like Flickr, Facebook and Twitter are so popular, there is an army of programmers developing ‘apps‘ that will seamlessly integrate various social media.

Things become more challenging for people like me who prefer to host their own content on their own websites wherever possible. Plug-and-play apps suddenly become much harder to source. And when they are sourced, only half of them work as intended, from my experience.

My cousin recently suggested that instead of manually typing a “wall post” in Facebook to advise my readers that I’d written another article, I should use an app like Networked Blogs to automatically ping Facebook. That way, a link to my latest blog post would automatically appear on my wall, just like my Flickr photographs do.

For both practical and ideological reasons, I am keen to minimise my use of third-party apps in Facebook. But the idea made me think about whether I could develop my own Facebook app to syndicate my own blog posts. Aside from removing the reliance on a third-party, it would also look rather impressive!

The Grapevine is powered by WordPress, which is installed on my web server. After some searching, I found a WordPress plugin called WPBook which would manage the sending part of the communication between my blog and Facebook. The best part is that the plugin requires one to develop their own Facebook application in order to manage the receiving part on the Facebook side. Perfect!

Following the detailed instructions, I was able to get the plugin installed in WordPress and an application generated in Facebook within 10 minutes.

In essence, this post is the final test… I should be able to publish this page on The Grapevine and then see it syndicated on Facebook a few minutes later.

Wish me luck!

Update, 27 January 2010:

The Facebook app and WordPress plugin have worked, except for thumbnail generation. Thumbnails will generate when I add a link by hand, but not when I use my new Facebook app.
