Internet Tools

This task seemed quite straightforward to being with. Use internet tools to trace the route from the internet tool IP address to the IP address of choice. This allows the user to discover any issues with the connection and to see at which point data transfer is failing (if it is).

Where the results of my trace route - indicating the IP address of the curtin.edu.au machine to be 134.7.179.53

The average times were
0, 0, 0, 0, 0, 0, 8, 7, 49, 50, 50, 201, 212, 217, 244, 247, 249, 244, 249, 250
and there were 19 hops from the tools site to the Curtin server.

In spite of reading howstuffworks.com, I struggled with how to interpret the data. I understood the first column to be the number of hops but was unsure about the next three columns. I finally took the first two of these columns to be the there and back route, the third column to be the avg of these first two figures (rounded up).

Further exploration

Ping the webct site and compare the time with the time taken to ping from the net tools site. Is it less or more than you expected?

Pinging the webct site from network-tools.com took on avg (over 10 pings) 248.2 ms

Pinging from a-Toolbar running off my computer took on avg (over 10 pings) 66ms

This was much faster than I expected. I had assumed that it would be faster from my computer (as it is based in Australia and network-tools.com server would be in the US) but wasn't expecting such a massive difference.

Traceroute from your computer to curtin.edu.au: compare the number of hops with the earlier traceroute. What sort of differences can you observe?

Number of hops = 15 to get to the final IP address as my earlier experiment from a web based site. Avg 4ms so again much faster.


I also found the data much easier to understand and interpret as it was laid out in a more orderly fashion.

I assume the speed difference is due to running from a machine based in Australia and tracing or pinging to another machine in the Australia. I also hazard a guess that using web based tools slow down the process compared to locally installed software.

CAPITALIZATION MATTERS!

Module 1, FTP task. My FTP experience was a little on the odd side.

I couldn't access the server using my FTP client (possibly a firewall issue but giving that FTP client 'access all areas' in the permissions didn't make a different. Ah... would the ol' restart have fixed that trick?)

However, I hit up the FTP site using Firefox. Volia, information at my fingertips in a matter of seconds. I knew there was a reason I preferred Firefox.

A while later...
SUCCESS! I changed FTP clients, ensured firewall clearance, restart of system and volia - it all worked perfectly. I think it's important to use applications with which you feel comfortable. You might have the greatest software on earth but it's useless if you can't use it.

I found browsing the folder structure at the destination site similar to using Windows Explorer to browse folder structure on a local computer. Once the connection was made, the rest of the task was easily undertaken.

To Telnet or not to Telnet?

Module 1, Task A required the use of a Telnet client to search for an author in the Deakin library database computer.

Success! Being a computer user since the days of DOS, this exercise was a blast from the past. The Telnet client was an old friend and the task was finished quickly and successfully with the information being forwarded to my student email address.

I'm comfortable in this environment where tasks are driven using keywords rather than an interface or menu.

I can't admit to having been in a library to use a catalogue database since 2004 but the system didn't appear to be all that different. Admittedly it didn't have the glossy buttons and the flashy menus down the left hand side but the use of alphanumeric characters to select choices was similar. I found it faster than the usual web based system as there was no waiting for multiple images to load. Overall it was easy to understand and use and I'd be opting for that approach again.

Module 1, Task B involved the Telnet client again (hello old friend) and zipping over to towel.blinkenlights.nl to take a look at the innovation of what could be achieved in this less visual medium.

I'm a fan! This was an awesome display of taking what was available and using it to create something 'outside the box'. Alphanumeric characters have never looked so good.

It is certainly a foundation for taking things to the next level. Rather than looking at the boundaries of the medium, take the other approach and see how far you can stretch it. Is that line in the sand really as close as you think it is?

Without innovative thinking we wouldn't have the interface of the internet that we have today. Blinkenlights was animation in its rawest stages and something that has simply been taken and built upon to have the animation seen regularly across the internet today.

A project like this provokes questions. How long would something like Blinkenlights have taken to produce? How many issues were a part of the process? How many times did the developers wish to give up because they couldn't quite make it work or didn't meet expectations?

Each stage of development is not without problems, glitches or bugs. It's about working within the boundaries of those limitations to produce something inspirational to add value to the development and evolution of the creation.

It offers inspiration to expand upon what is currently considered the industry standard - if something so visual can be created within that forum then what possibilities does that offer for the future? Are we limiting ourselves with the interfaces currently available? Is everything becoming too complicated in a bid to make it user-friendly and not simplistic enough to allow for the evolution of the next generation of internet and animation?

Top 5 tips for new bloggers

Success! I have created my blog! I'm now ready to starting journaling my thoughts and progress online. Let me start with some handy hints for would-be bloggers.

Is blogging today's version of the written diary from generations past? Is this just another way that we add to the voyeuristic nature of the reality-TV world we now live in? Should a blog be treated as a personal space or as nothing more than a web based magazine and the blogger a columnist jotting down opinions and experiences for all the world to see?

Tip One: Uncover your purpose for blogging
Before starting your blog - whether self-hosted on a personal website or a part of a blogging system such as this one (blogger.com) - ask yourself what is the purpose of the blog? Who will my audience be? What blogging tools should you use? Where should the blog be hosted? Is this an anonymous series of posts or a friendly interaction with like-minded souls? Are you sharing information or sharing yourself?

Blogging is like anything else. It starts out as novelty factor and can quickly become mundane, boring and yet another chore that we have to fit into our busy lives. Blog with passion. Write about something that drives you. Whether it's a forum to fill your friends in on your day-to-day life or a way to share your favourite hobby with other enthusiasts, it's easier to write about something you know and love.

What is written without effort is in general read without pleasure. Samuel Johnson

Tip Two: Blog with integrity
I see blogging in the same vein as having a conversation with yourself - you wouldn't plagiarize someone else's thoughts or knowing give yourself false information and the same rules apply with a blog.

I also live by the rule that I don't post anything I wouldn't want my mother to read. It's a good tip. You don't know who is reading your blog and what your interaction with them is or will be. It could be a future employer or mother-in-law.

Nothing gives an author so much pleasure as to find his works respectfully quoted by other learned authors. Benjamin Franklin

Tip Three: Make your blog user friendly
Okay, so you've created the blog and posted until you can type no more. Your blog counter is registering minimal hits (and you suspect they are all coming from your mother!). What can you do?

Make your blog user friendly. Tell potential readers a bit about yourself, why your blogging, invite comments. Don't hide behind the anonymity of the internet.

Do:
– Write a short biography
– Upload a photo of yourself
– Give your blog titles that have meaning and summarize the content of the blog
– Label links appropriately click here is only encouraging for the very adventurous or the very bored, the majority of readers want to know what they are linking too
– Don't rely on the archive posts feature for readers to find your best work - set up a
Top 10 of links to your favourite articles. It's not that brilliant if no one can ever find
it again.
– Use a design that's easy on the eye - dark text on a dark background is hard to see.
You won't encourage return visitors reading your blog causes eyesight loss!

Tip Four: Blog regularly
I'm the first to confess I'm a random blogger. I blog irregularly and I lose my audience. Only the steadfast readers (I think it's just my brother) continue to check back often. It's hard to post when you don't feel that you have something to say but it's important to establish a pattern for the readers to follow. If the reader can anticipate that you will update your blog on the first of every month then they know when to check back. If you blog once in January and not again until October, it's hard to establish a regular readership. Set expectations that you know you can meet (or even exceed).

Tip Five: If you are serious about blogging, buy a domain name
If blogging is more than a passing phase for you then buy a domain name - they are relatively inexpensive these days - and set up an easy to remember URL for your blog. Make it easy for people to find you (and what you have to say)

Enjoy your blogging!
