Teaching NAT in CCNA4

Recently as I was preparing to teach CCNA4 chapter 5 on NAT (Network Address Translation), I decided to put additional information in the introduction to draw the students attention to the state of IPv4 particularly in our region and country specifically. This would then set the basis for me to introduce NAT and its purpose as an immediate solution to IPv4 address exhaustion.

Here are some links I found in my research that I thougth would be helpful to other instructors who are preparing material for teaching.

• Allocation of IP addresses by country - You can find your country and extract the information needed to give your students an overview of the number of addresses allocated by IANA to your country.

• Major IP Address blocks - This site gives you blocks of allocated addresses but does not indicate which ISP uses what block, the next link does show you further info

• Gateway information and address blocks by ISP's in your country - this is a very useful site as it gives you additional info about your country's gateway as well as the block allocations to ISPs that operate in your country.

Tinkering with Raspberry Pi

Sometimes when you get handed something new and interesting, you have two choices; you either put it away or you start tinkering over it. If you like tinkering over new and interesting gadgets, you will soon learn one or two things about it (even become good at something).

That is exactly what happened to me when I was first given a Raspberry Pi 2 two years ago by the head of our department.

Raspberry Pi 2

•Small computer
•Make, learn, design in a fun way
•Quad core CPU
•1 GB RAM (Pi 2)
•40pin GPIO
•Micro SD slot
•4 USB ports, HDMI, Stereo output, DSI display
•Micro USB power source

  

 

 At first glance, I had some idea what it could be but I never knew what interesting things you could do with such a very small thing, almost the size of your BSP Kundu card.

What tools I use for screen capture

When it comes to doing screen captures for my lessons or short tutorial videos for my CCNA classes, I've always relied upon Camtasia Studio to do all these. After I compile the videos, I upload them to Moodle (the LMS that we use in DWU).

Speak To Me In The Stillness Of My Heart

SPEAK TO ME IN THE STILLNESS OF MY HEART

By Picky Airi

Reading: 1 Samuel 3:1-11

Do you have time to listen?

There are times in our lives that we so often talk too much. Imagine there are two people communicating, and only one person is doing all the talking, never trying to listen. In any culture there are always basic protocols (rules) of communication. For example, when we meet a wantok, we shake hands first as a sign of greeting or sometimes say a simple hello before anything. Then after the initial gestures, we start to verbally communicate.  

Poem: Goodbye My Dear Friend

I’m not good in writing poems but I decided to write this one today (23.02.16) dedicated to my former teacher, mentor, toastmasters coach and a special friend, late Mr. Jun Pasilabban.

Goodbye – My Dear Friend

Morning tea today

Wasn’t like any other day

Why switch to Windows 10? Why not open source?

While it is good to have Windows 10, I doubt the stability of this OS. I have used Windows 8 and 10 only recently on one of my machines and its (Windows 10) lack of stability is really an issue for me unlike the experience on Windows 7 or Windows 8/8.1. And based on tech forums and articles I'm reading, I am not alone. Example here

Although Windows 7 has been granted a 2 year extension on the shelf  (Microsoft's sales life cycle), the move has been on snail pace for many users from Windows 7 to Windows 10. 

Another one of those must have tools for the "eTeacher"

As a teacher who relies heavily on ebooks as reading resources and reference material for students, I download a lot of ebooks from the internet. One problem I have come across is how do I split the PDF to extract only the pages I want to give the students and leave out the rest.

Rather than copying the entire chapter and pasting to word which I used to do before I decided to do some googling to find out if there is an app that can split the PDF and give me just what I want. (This feature is built into adobe pdf but you will have to register to use it which I couldn't.)

Integrate Camtasia Studio with Moodle

It has been a while since I last posted any tutorial here. Been very busy with work and family that I wasn't able to write something. However, I did get to participate in a very enlightening course over the course of three weeks on teaching online.

It was through this course that I started to assist the facilitator teach some of my colleagues on how to use Camtasia. Camtasia is a great screen capture tool. I shall not go into the details of the software as there is tonnes of info on their website (a simple Google search would do) but I would like to share a tutorial I wrote on how to integrate Camtasia with Moodle. Moodle is an open source LMS with a huge support its community of users. You can find more about Moodle here. 

Calls To Preserve Motuan Art of Tattooing

I am very glad to hear that calls have been made to preserve the Motuan art of tattooing. I stumbled upon this footage produced by EMTV on EMTV online .

As a Motuan myself, I have great respect for for the tangible and intangible cultural heritage that identify us as Motuans.
