Module 2 - Lists vs Discussion Boards

Lists

Email lists automatically send mail to people who have requested to receive messages from a particular group and in return can send emails to the group.

I joined a list in Yahoo for Webmasters which sent me an email daily which included a message each day. Unfortunately that message was the same each day and was spam “earn $20, $50, even $100 per hour working from their home”. Not quite what I was expecting as the list mentioned there was new activity daily.

I also joined Topica to a list named Linky & Dinky (reviews of useful – and bizarre – web sites). I’ll add to this post when I start receiving emails from this list. Well, I have started to receive emails from this list and at first they went to my spam folder so I wasn't aware I was receiving them. They are mainly spam and I have since unsubscribed from this list.

And, I also joined Freecycle which is another I have yet to receive any emails from. I have also started receiving emails from Freecycle which I find useful. They list different items for free in a particular are, although they can quickly fill up your inbox if not kept up to date.

Discussion Boards

Discussion boards are a community of likeminded people who post topics for discussion and people can comment on each others messages.

What are the pros and cons of email lists versus discussion boards? (Allen, M., n.d.)

I contribute to discussion boards regularly. Mainly through my work if I am using software I am unfamiliar with or am trying something new, I will search for relevant discussion boards and post questions. Usually, I receive a reply, sometimes within a day, other times it may take a week. If you need an immediate response, then a discussion board can be limiting however I find there is a sense of community and others who are more informed are more than willing to help.

Are there certain kinds of communication or purposes more suited to one than the other? (Allen, M., n.d.)

Depending on what you want to receive or whether you want to be more active in your posting, both forms can be of use. The lists seem to be a bit outdated and has been superceded. Discussion boards are more active and have more of a community feel about them.

Module 2 - Email

It is quite interesting to look into something I do everyday without thought. I use Outlook at work and use a web based email at home - Yahoo. I chose Yahoo as I have changed internet providers over the years and it is annoying to have to change email addresses each time.

1. What information about a user's email, the origin of a message, and the path it took, can you glean from an email message? (Allen, M., n.d.)

Looking at the emails I receive, I can find the following information without opening the email: who it is from, the subject of the email, date it was received, file size, attachments (if any).

If the subject field had "Re:" before the subject, I would automatically know this is a reply to a previous email I have sent to the recipient.

This is quite a lot of information without opening the email.

Upon opening the email, I can see the email address consists of a username, an "@" symbol, and a domain name. If I didn't know who the email was from, the domain name provides a lot of information.

The domain name can be a comany name, business name, individual's name, internet service provider, etc. The domain name extension can also be useful to determine where the email has come from: .com, .net, .org, .gov, .edu. These extensions can represent companies, government departments, education services, etc. They can also represent countries where the email has originated: .com.au, .co.uk, .co.nz, etc.

You will also be able to tell if the email has been copied (cc'd) to anyone else and, if the email has been forwarded many times over, there is usually a trail of email addresses that the email has left if you were to follow the breadcrumbs.

2. In what cases would you find it useful to use the 'cc', 'bcc' and 'reply all functions of email? (Allen, M., n.d.)

Cc
I use cc in many emails at work and a few from home. If I think a topic is of interest to other people but not necessarily an action for them, I will cc them in on the email. It is primarily used for information purposes.

Bcc
I very rarely use this function but it can be worthwhile. It is primarily used for sending group emails or newsletters when you don’t want recipients to know each other’s email address. It is illegal to send an email to a group of recipients and display all email addresses.

It can also be used when you want to inform someone of an email’s contents but you don’t want the recipient to know you have sent it to someone else. This can be used to 'cover your back' however it can be risky and can backfire. Be careful when using this function for this purpose and ensure the person you are bcc’ing in the email is aware of why you are using this function.

Reply all
If I was to receive an email which was sent to other recipients and I wanted to reply, I would take into consideration the message and whether everyone on the address lists need to see my reply. If it is only necessary to reply to the sender, then I will only reply to the sender. If, however, I think it is necessary to advise everyone of my response, then I will reply to all.

Usually, the original email and its contents will enable me to make a decision on whether to reply all. Normally, with work emails I will tend to reply to all as the sender would like everyone informed when replying. If I were to send an email to multiple email addresses and it is not necessary for anyone to reply, I will add FYI (for your information) at the beginning of the email so everyone knows they don’t have to respond.

3. In what ways can you ensure that an attachment you send will be easily opened by the receiver? (Allen, M., n.d.)

I have received attachments in email that I cannot open as I didn’t have the correct version of the software. It is important to make files compatible for the end user when sending attachments. It is frustrating and annoying having to ask the sender to resend the email in the correct format.

Also, sending Macintosh or Windows files to recipients who use a different operating system are unable to be opened by users.

Normally within my work environment everyone uses Windows so it is not usually a problem. However, the graphic designer we use has Macintosh and when I receive files sometimes they are not in the correct format for me to use.

If there are problems with users receiving attachments, you can send the document as a plain text (ASCII) format or a rich text file (RTF) format. The downside to sending these files is all formatting will be lost.

I usually state the files I have attached in the email in case I forget to attach them when sending so the user knows there should be an attachment(s).

Also, if I want to send many files or if the files are large, I will zip (compress) the file before sending. This ensures the recipient will not receive any large emails in their inbox. If I am sending photographs to family or friends, I will reduce the file size to ensure they will receive them and the download time is minimised.

Any exe or zip files I receive at work do not get through our firewall and need to be sent via our IT dept to scan for viruses. It is important to remember NOT to open any attachments from recipients you do not know. If you do know the recipient you still need to be cautious before you open any attachments as some viruses can be spread this way. Any attachments with exe extensions can be dangerous and should be opened with caution.

4. What sorts of filters or rules do you have set up, and for what purpose? (Allen, M., n.d.)

I use filtering quite extensively at work as it unclutters my inbox and saves time. I have registered for numerous newsletters as I create newsletters as part of my job and like to see how others are formatted.

For these newsletters I have a rule to place them in a folder automatically when received so I can view them at my leisure. I also have email I receive from an organisation which is for information purposes so I don’t necessarily need to read as soon as they come in so they are also put in a particular folder.

The filters I use are by email address as I know the email addresses they are distributed from however there are many ways you can filter email. You can filter by keywords, subject messages, and email addresses to help you manage your inbox.

It is a good idea to experiment first to see what your email software is capable of.

5. How have you organised the folder structure of your email and why? (Allen, M., n.d.)

I have created folders for both my work and home email addresses for email I want to keep. It can get confusing if there are emails that relate to many subjects. It is important to plan the structure before creating the folders. It is like any filing system which needs to be planned out to achieve the best result.

It can also be useful to keep sent emails in these folders as it can be time consuming and frustrating to sort through sent emails.

If space is an issue, emails can also be saved to your computer for ease of access. I keep my folder structure on my computer similar to my email folders which helps me keep organized.

Module 1 - Internet Tools

For this task we were asked look at the traceroute tool and the ping tool.

I used Network-Tools.com to traceroute to curtin.edu.au. Details are below:

134.7.179.56 is from Australia(AU) in region Oceana
TraceRoute to 134.7.179.56 [curtin.edu.au]

Trace complete

Looks like a lot of gibberish to me and it doesn't make it easy when it is formatted like the text above. But basically there are 6 columns. The first column which is numbered from 1-18 are the number of hops it has taken to get from my destination to the Curtin server. It took 18!

The next 3 columns are the responses from the router and how long it took (in milliseconds). Each hop is tested 3 times. Where it says "Timed out" there was no response from the router so it tried a different router.

The fifth and sixth columns are the IP Address and Host Name of the routers we had to pass through to get to the Curtin server.

Using the 3 millisecond figures for the last traceroute, the average time in milliseconds from the tools site to the Curtin server was 298ms.

I then tried to Ping the Curtin website using Network-Tools.com. Details are below:

Ping 134.7.179.56
[curtin.edu.au]
Round trip time to 134.7.179.56: 309 ms
Round trip time to 134.7.179.56: 298 ms
Round trip time to 134.7.179.56: 308 ms
Round trip time to 134.7.179.56: 295 ms
Round trip time to 134.7.179.56: 296 ms
Round trip time to 134.7.179.56: 295 ms
Round trip time to 134.7.179.56: 295 ms
Round trip time to 134.7.179.56: 298 ms
Round trip time to 134.7.179.56: 298 ms
Round trip time to 134.7.179.56: 296 ms
Average time over 10 pings: 298.8 ms

Interestingly, both traceroute and pinging took about the same time to locate the server. Traceroute seems to supply more information as to what servers it has passed to get to the destination so may be a more reliable.

The IP number for the Curtin server is 134.7.179.56

I also downloaded A-ToolBar from the Tucows website (http://www.tucows.com/preview/323577) and tried pinging the Curtin server and it pinged it in 5 hops. I then tried to trace cutin.edu.au using A-ToolBar and it only took 1 hop. I'm not sure if this result is correct so it is worthwhile to try out different applications as you may get different resuls.

They are both quite handy tools if you had a website hosted externally and you were unable to access it. Using both of these tools you would be able to find the exact place where the connection is dropping out.

Below is a screen shot of A-ToolBar when I pinged the Curin server in 5 hops:




What is Traceroute ...?
traceroute is a computer network tool used to determine the route taken by packets across an IP network.
Source: Wikepedia (http://en.wikipedia.org/wiki/Traceroute)

Still confused? Me too!
Traceroute is a command which can show you the path a packet of information takes from your computer to one you specify. It will list all the routers it passes through until it reaches its destination, or fails to and is discarded. In addition to this, it will tell you how long each 'hop' from router to router takes.
Source: MediacCllege.com (http://www.mediacollege.com/internet/troubleshooter/traceroute.html)

What is Ping ...?
Ping (Ping referred as Packet Internet Grouper) is a computer network tool used to test whether a particular host is reachable across an IP network; it is also used to self test the network interface card of the computer, or as a speed test. It works by sending ICMP “echo request” packets to the target host and listening for ICMP “echo response” replies. Ping measures the round-trip time[1] and records any packet loss, and prints when finished a statistical summary of the echo response packets received, the minimum, mean, max and in some versions the standard deviation of the round trip time.

Module 1 - FTP Task

For this task I downloaded an FTP client for my computer - I used FileZilla (http://filezilla-project.org/).

FTP to the Curtin ftp site and download a file readme.txt and complete the sentence.

This server runs on a unix platform, so CAPITALISATION MATTERS! (sorry had to change the spelling)

I use FTP with work, mainly for transferring large files to printers, graphic designers and any other provider who does design work for us. I also use ftp to upload files on an external website.

I found it easy to download the software and as I was familiar with FTP applications, finding the file and downloading it was no problem.

The FTP client I use at work I have set up so depending on who I am FTPing, the directory structure appears. So for this exercise, trying to locate a directory I wanted to download was the only issue. Once I found a directory to download the file, I dragged and dropped the file to the directory.



What is FTP...?
File Transfer Protocol (FTP) is a standard network protocol used to exchange and manipulate files over an Internet Protocol computer network, such as the Internet. FTP is built on a client-server architecture and utilizes separate control and data connections between the client and server applications. Client applications were originally interactive command-line tools with a standardized command syntax, but graphical user interfaces have been developed for all desktop operating systems in use today. FTP is also often used as an application component to automatically transfer files for program internal functions. FTP can be used with user-based password authentication or with anonymous user access. The Trivial File Transfer Protocol (TFTP) is a similar, but simplified, not interoperable, and unauthenticated version of FTP.

Module 1 - Telnet Tasks

For this task we were asked to download Telnet and 'telnet' to the following address:

telnet://library.deakin.edu.au

I found telnet quick and easy to use. If I used it more often and was familiar with the commands then would find it more comfortable, however, I prefer to use a web-based interface as there are more options and related links.

Telnet reminds me of DOS prompts and I was always getting my commands mixed up when using DOS.

In searching for the author Bennahum there were a series of commands we had to input to find the results and then were asked to email the results to ourselves.

The email contained the following information:

You searched for the AUTHOR: bennahum
2 AUTHORS found, with 2 entries; AUTHORS 1-2 are:
1 Bennahum David A 1936 ................................. 1 entry
2 Bennahum Ninotchka .................................... 1 entry

We also looked at telnet://towel.blinkenlights.nl

Wow - someone sure had a lot of free time. Star Wars fans should watch this although it might be quicker to watch the movie. Its a fun way to see how Telnet can operate and its capabilities.
It also gives some insight into how much further we have gone using the internet and technologies.

Being able to use earlier technologies we can see how the internet has evolved. The company I worked for 10 years ago had a website which was a portal to download files. Users would either ftp or http to the site to download reports on a daily basis. The site consisted of no other content.

There has always been a need to create applications purely for pleasure as blinkenlights shows. The internet has produced a lot of useful applications and technologies but there is also a creative side which focuses on user experience.

The technology now used to search the internet is sophisticated and constantly changing to produce the best experience for users. User experience is top priority and with so many choices the competition is fierce. This can only benefit users who are spoilt for choice.


What is Telnet ...?
Telnet (Teletype network) is a network protocol used on the Internet or local area networks to provide a bidirectional interactive communications facility. Typically, telnet provides access to a command-line interface on a remote host via a virtual terminal connection which consists of an 8-bit byte oriented data connection over the Transmission Control Protocol (TCP). User data is interspersed in-band with TELNET control information.

Top 5 tips for new bloggers

My top 5 tips for new bloggers are:
  1. research the blogging platform you are going to use to ensure it has the capabilities you require.
  2. have a look around the blogging platform to find handy tools and information on how to change settings, layout, etc.
  3. update your blog regularly.
  4. don't be afraid to be yourself.
  5. have fun!
I will also be following these tips as am a new blogger myself, so will update this list if I find more useful tips.

After trial and error in creating my blog I have found a few more helpful tips:
  1. I'm not sure whether this is for all blogs but it is helpful if you are typing up your blog entries in word and then copy and pasting into your blog to use Notepad. Copying into Notepad and then copying again into your blog will stop unwanted code in your html. Unfortunately you will have to then re enter any links or other formatting.

My first Blog ....

It's a bit overwhelming really, considering potentially millions of people could be reading this. Realistically, I'll be lucky to get more than one person reading my blog which makes it a bit easier to write.

This year I have started my my BA Internet Communications and this unit is NET11 The Internet - Communications. This blog is part of the unit's assessment so will be adding some tasks and writing reflections on the unit.

Stay tuned!
