Assignment

Sorry i havn't blogged for a while but i have really exciting news. I finished my assignment which i had to make a game on the program scratch. Soo i finished and sir had a look at it. So i'm gooooood. Things that i had difficulties were mostly at the beginning like get the ball moving, putting the points and speed of the ball. But at the end i had great fun playing it...

SO TALK TO YOU LATER.I MEAN NEXT YEAR!!

Finally, i finished my tutorials and my challenges. I now can start on my assignment so i better get started.

Tutorial #5

Finally this is my last tutorial. Thank God...

So this one you click on each of the drums and the colour effect will change (hopefully)

Here it is....

Taaa Daaa

Tutorial #4

This post is about my 4th tutorial i have managed to do. Hope i did well enough to make Mr Lennon happy. So here it is...

Basically what it is once you press the green flag the shark starts to move but when you are ready click on the fishy and he will start to move aswell. Once the shark touches the fishy the score board will increase. So yehh...

Interactive twirl

No say to this. Quite simple.

Point towards the mouse

I felt like i was loved. While i was moving the mouse it was following me..

Changing colour

s

This was quite ok changing colours. Hopefully i will use it during my assignments.

Scratch challenge #3

This challenge was quite difficult. I think i went out of patience. The main thing is i got threw it.

Scratch Challenge #2

Here is my scratch challenge number 2.

Scratch challnge #1

Gliding scratch

This is how i mangaed to do scracth cahllenge #1

Windows 7

Today we are in another classroom with no computers, due to year 10 exams in the computer rooms. So our teacher printed sheets about Windows 7. We just read it and had to answer some questions.

1.What versions is Windows 7 available in ?

• Home premium
  
• Professional
  
• Ultimate


• OEM


• Enterprise
  

2.Describe some of the features of the new task bar.

Pinned programs usinglarge, easy-to-see icons. Mouse over one and all windows associated with that program appear in preview. Hover over the preview to show a full-size preview of the program.

3.What are jump lists and how will they be useful?

Jump lists are made to make the recently opened documents easier to get to.

4.How can one quickly size two windows to fill the desktop side by side?

If you want to use 2 programs at once.

5.Research and describe the 9 multi touch gestures that windows 7 uses?

Tap and double tap; Basic touch action. This is what a click and double click does.

Panning with Inertia; This is for scrolling. Drag any part of the page up or down with one or more fingers. This works in most applications that use standard scrollbars.

Selection/Drag; This is like drag ans selection. Touch and slide your finger on the screen. This will move icons around the desktop.

Press and tap with second finger;This is like a right click. Press on target and tap uising your second finger.

Zoom;This is the same using the CTrL key + scrolling. Pinch two fingers or apart to zoom in or out on a document.

Rotate;Touch two spots on a digital photo and twist to rotate it is just like a real photo. Move two fingers in opposite directions or use one finger to pivot around another.

Two finger tap;Tapping with two fingers zooms in about the center of the gesture to default zoom.

Press and hold;Same as right click. Hold your finger on screen for a moment and release after the animation to get a right-click.

Flicks;Flick left or right to navigate backwards and forwards in a browser or application. This is very natural when one wants to flick.

Scratch

Today i also started playing around with the program called scratch. It looks pretty hard soo i am going to see wat i can get out of it today. So far i got the three control structures and they are:

• sequence



• selection
  


• repetition

Sample flowcharts

Basically the flowcharts just explain the steps of what you are doing. You just need to follow the instructions in the flowchart.

“Computers never do what you want them to do, they only do what you tell them to!"

Algorithms: an algorithm is an effective for solviong a problem using a finite sequence of instructions.

Pseudo code: This cannot be compiled, there is no real formatting rules. It is simply just one step - in producing the final code.

Machine language: Only used by the languages that are understood by the computers. This is almost impossibel to use because it it entirely numbers.

High level computer language: These are translated into assembly or machine language by a complier.

If you have trouble reading this image you may click on the image and it will show you a clearer image.

Flowchart: Common type of diagram that represents an algorithm or process showing the steps of boxes as various kind and there order by connecting them with an arrow.

Symbols used in a flowchart:

Scratch

Finally we finished our projects. Today we started on this new project. It looks hard but sir said that once you have done the tutoriuals you will be experts by the end of the holidays.

By the way this is what scratch looks like.

This is what it looks like. So i am going tyo play around with this for the next hour.

Thankyou

Researching

Today we got our due date finalized. The due date is 2 weeks from now. We have 5 ist lessons and i better get started. So my plan is to do 1 topic every lesson and do somethings at home.

Today we recieved our school windows live email. Sir gave our passwords so we could access our new accounts. We obviously chand our passwords



Note: For IST this is my 4th account i have made.



So basically it is the same things as our normal hotmails at home. With this school email we can use powerpoint, word and all those sorts of things online. We have 25GB free space available. This issss soooo koool.

New Idea

Today Adeng and i are going to work on seperate scrapblogs. We both have different accounts, this idea is changed because if someone publishes their work on scrapblog first, it is published that is no problem, but if the other person wants to publish there one it overwrites the first one. This is why we chose to make our own scrapblog accounts.


Soo yehhh.

What is the function of the CPU?

The function of the CPU is the microprocessor.



What was the name of the firts CPU?

The first microprocessor was the Intel 4004 introduced in 1971.



Referring to the graph on page 2 of the article, describe how the speed the CPU's has changed?

It is gradually increasing.



What does MIPS measure?

MIPS stands for "million of instructions per speed" and is rough measure of the performance of a CPU.



Research what a dual core processor, what is multitasking and how to do the two work together.



The dual processor has two cores on the same die. Multiprocessing in a single physical package. Cores in a multi-core device may be coupled tightly or lososely.







Ok now that i have finished these set of questions i can move onto the CPU quiz.



Talk too youuu laterr....

Preliminary Quiz on Digital Data

Today i am basically trying to keep up with my t3 instrtuctions. I am not that far away i just need to complete a Quiz on Digital Data. I hopee i did ok.

Researching

Today i totally forgot my password for my scrapblog account. There was this icon reading Forgot your password? So i clicked it and i had to type my email address and it sent my password to my home email soo when i get home i will check it and write it down somewhere so would'nt forget it.

Anywayzzz i decided to do a bit of researching on my topics. At least my time went for nothing.
Soooo yehh.

Talk to you later...

Scrapblog

Today we made an account on scrapblog and it seems good. We are playing around on it. The things i saw to day about scrapblog is you can create your own personal profile to display your creations. There is a specified button labelled publish and save. That is a way of people knowing how to save and publish your work. Also on scrapblog you can add videos, photos, backgrounds of your choice and many other things. Thats it for now and if there are any other things unique about scrapblog ill put it up.

Today Adeng and i were re-thinking about not using nota because it seems to be complicated publishing and doing all sorts of things wheras scrapblog has more tools and more of a variety of all sorts of things. Scrapblog seems to be understandable and easy of use. The reason of changing from nota to scrapblog is because nota didn't seem like we expected. We thought we could do many things while presenting our assignment. We made an account on nota and started trialing on it to see if it was any good. But when we went to the stage were we were going to publish our work on blogger it was not understandable how to do that. That was a biggest struggle about nota. So now we are changing our presentation page to scrapblog.

Today i was discovering what i can do and not do on notaland.

The things i found on nota that are unique are:

• The user can create a visual presentation in a couple of minutes using any web browser.


• The design and the use of the website are simple, understandable and can be done in minutes.


• Constantly nota is being expanded, beautifies and becomes more advanced.
• Materials can be shared and/or edited with other group members.
• The work created by the ser never is lost-it is saved automatically and also published.
• Free of charge.

If you want for yourself to check up this website and see if it is any good for you the link is...

http://www.qlipmedia.com/


The one Adeng and i chose was notaland. The link is below so check it out.

http://notaland.com/

Today i worked out the task and who my partner is going to be. My partner for this task is Adeng. Today we basically went threw different presentations. We have many choices but we are still confused about which to pick.

Today we had 2 choices and they were Qlipboard and Nota. They were very hard to choose from. In the end we both agreed on Qlipboard. As we were making an account it said we need to install a pug to make the account exist. Our hopes went down and we were looking forward on this. Anyway we could'nt access the account because it wouldn't let students username install they need an adminastrator. Wheras nota works perfectly and it doesn't need any installing business and we can use our emails/usernames as we login everytime.



Anyways our next preference was nota so we have made an account and chose what topics are we going to do.



We will see what will happen as the time passes by.

The world of multimedia

Where do you commonly use multiedia in your daily life, list as many examples as you can?

We commonly use multimedia in our daily lives and some of them are television, computers, internet, DVD, BluRay and Ipods.



What multimedia device or service would find it hardest to be without? Discuss.

It depends on your character and which multimedia device you prefer the best. It would be hard for me to live without my phone, TV and computer. Without my phone i feel something isn't right and just in case of emergency purposes. My TV i watch it everytime i eat dinner and everytime i want to watch a movie(boredom). Computer because of Internet and practically for school work.



Do you think the video on the future directions (second video) will come true? Do you see any advantages/disadvantages to such a lifestyle?

I think the video of the second video will come true. I reckon it would be great to have something like this. The advantages of this device is just talking to the computer and it does whatever you tell it to do. The diadvantages of this is you become lazy.

Data Compression

What is data compression?

In computer science and information theory, data compression is the process of encoding information using fewer bits than an unencoded representation would use through use of specific encoding schemes.

What is a data compression ratio?

A data compression ratio is also known as a compression power. This is a computer -science term used to quantify the reduction in data representation size produced by a data compression algorithm. The data compressio ratio is analogous to the physical compression ratio used to measure physical compression of substances. This is defined as the ratio between the uncompressed size and the compressed size.

Why is data compression an important technique for the online world?

The data compression is an important technique for the online world because it is helpful for their data compressed and uncompressed.

What is the difference between Lossy and Lossless data compression?

Lossless compression shemes are reversible so that the original data can be reconstructed, while lossy shemes accept some loss od data in order to acheive higher compression.

Which method offers the greatest compression ratio?

The compressio ratio of lossy video is nearly always far superior to that of the audio and still-image equivalents. Video can be compressed immensely with little visible quality loss.


Why is human psychology and perception an important factor in methods of Lossy compression?

In some cases the ideal is a file which provides exactly the same perception as the original, with as much digital information as possible removed.

Name Lossy file formats for audio, still image and video format.

Lossy compression is transprent which can be verified via an ABX test.
Image:
JBIG2
PGF, Progressive Graphics File(lossless or lossy compression)
Wavelet compression
S3TC Texture compression for 3D computer graphics hardware.
Video:
H.261
H.263
H.264

Dolby AC-3

Rss feed

Define RSS Feed?

RSS stands for Really Simple Syndication.
It is the format for distributing news and other web content. When you put content into RSS and send that content to other people or websites, it's called a feed.

What goes in the feed?

You can add text, audio, images, logos and video to a feed. The feed contains an index - a list of items - and each one is identified by a link o the content on your site. Most RSS feeds include a title for the link and a description of the content. When syndicating your content, use an eye-catching title and interesting description of the full content.

What can a feed do for you?

The RSS feeds keeps your audience updated. They let people see your content without going to the website.

How are feeds different from email?

The feeds are similar to emails but not quite the same thing. It updates your profile but it doen't let you know.

How do people read feed?

Reading the feeds is similar fro using a radio. The station sends out the programs and you would need a radio to pick up their shows.

How do you find the feeds you want to subscribe to?

Subscibing your feeds with search engines, this will increase your search engine visibility.

New terms relating to audio files


Stereo
A system or equipment for reproducing stereophonic sound.

Channel
A path for the transfer of signals or data within a computer or between a computer and its peripheral equipment.

Track
A data-recording path on a storage medium, as a magnetic disk, tape, or drum, that is accessible to a read-write head in a given position as the medium moves past.

Frequency
The number of items occurring in a given category.

Hertz
The SI unit of frequency, equal to one cycle per second. Abbreviation:


Decibel
A unit used to compare two voltages or currents, equal to 20 times the common logarithm of the ratio of the voltages or currents measured across equal resistances. Abbreviation: dB, db

Wav, mp3, aiff
This is a list of different audio files.

These are new terms i learnt relating to audio files.

Introduction to Video

The video format we will be using this term is Digital video, what is the other, older format that was used recently.

The other, older format that was used recently was the analog video.


Describe the difference between the two formats.

Analog signals are made up of continuously varying waveforms. The value of the signal can be given at any given time, can be anywhere in the range of minimum and maximum .Digital signals are transmitted only as precise points selected at intervals on the curve. The type of digital video that can be used on the computer is binary, describing these points as a series of minimum and maximum values- minimum represents zero and maximum one.


Analog Signal

Digital Signal

Binary Signal

What are some advantages of digital video?

There are many advantages of Digital video, the most very important on is very high fidelity of transmission as to supposed to analog. With a digital signal, it is much easier to distinguish the original
Information from the noise. So a digital signal can be transmitted and duplicated as often as we wish with no loss in fidelity.


What is meant by frame rate in video?

The number of pictures being showed per second is called the frame rate. It takes a frame rate of about 10 frames per second for us to perceive smooth motion. Higher frame rates make for smoother playback.

Do all applications use the same frame rate, explain your answer?

No, because everyone wouldn’t use the same number of frame rates and/or the same type of video – Analog or Digital Video.

What is meant by resolution, how is it measured?

The quality of the movies you watch is not only dependant upon frame rate. The amount of information in each frame is also a factor. Tis is known as a resolution of a image. Resolution is normally represented by the number of individual picture elements that are on the screen, and is expressed as a number of horizontal pixels times the number of vertical pixels e.g. 640x480

What is the colour system called RGB?

RGB stands for Red, Green and Blue components of a colour. Computers monitor display RGB colour. Each pixel we see is actually the product of the light coming from a red, green, and a blue phosphor
Blue components of a color. Our computer monitors display RGB color. Each pixel we see is actually
the product of the light coming from a red, a green, and a blue phosphor placed very close together.
Because these phosphors are so close together, our eyes blend the primary light colors so that we
perceive a single colored dot. The three different color components — Red, Green, and Blue —
are often referred to as the channels of a computer image.

Explain the video standards PAL, NTSC, and SECAM, what are the main differences between them.

The SECAM format is only used for broadcasting. In countries employing the SECAM standard, PAL format cameras and decks are used. Remember that the video standard is different from the videotape format. For example, a VHS format video can have either NTSC or PAL video recorded on it.

Which standard do we use in Australia?

Australia uses PAL.

For what type of video camera would you need to have a Video Capture Card in your computer to download?

Many computer system now ship with the IEEE 1394 interface as a standard feature. Your card choice will depend upon how you answered the questions posed above. In many cases, once you have determined your card that will also determine your computer. This is because many types of cards are only available for one type of computer platform. There are video cards. These are:

1. Types of analogue video input/output supported
2. Types of digital video input/ output supported
3. Types of video compression supported
4. Types of special processing supported
5. Types of software included
6. Types of audio supported.


What is an IEEE 1394 port?

The IEEE 1394 interface can be used for many others
Connections as well, such as hard drives, scanners, and networking. The simplest kind of card available is the IEEE 1394 interface card. This card is used to add the IEEE 1394 interface to computers that did not ship with one. This card does not support any analogue video. Many computer systems now ship with the IEEE 1394 interface as a standard feature.



Why do digital video cameras use video compression?

Digital video cameras use video compression because it will take a large amount of space. Compression is necessary because of the enormous amount of data that comprises uncompressed video.
A single frame of uncompressed video takes about 1 megabyte (MB) of space to store. You can calculate this by multiplying the horizontal resolution (720 pixels) by the vertical resolution (486 pixels), and then multiplying by 3 bytes for the RGB colour information.


Describe what a codec is.

Codec’s may be found in hardware — for example, in DV camcorders or capture cards — or in software. Some codec’s have a fixed compression ratio and therefore a fixed data rate. Others can compress each frame a different amount depending on its content, resulting in a data rate that can vary over time.


What is meant by generation loss, where does it happen?

Generation loss does not occur when copying digital video unless it is repeatedly compressed and decompressed.

Olympic Rings

This is my creation of my Olympic Rings.

This was pretty ok by using the two programs. The disadvantages of this is by putting the rings together to make it look like its actually stuck together. =)

Veritas animation

23/3/09

Today was the day i started to work on my assignment. The first thing i had to do was to choose from Inkscape and Gimp. So i picked Inkscape because it looks simple and looks easy to shuffle round with.

24/3/09

I drew out my sketches of my animation. I had a bit of trouble starting. The main thing was that i haven't used it before but as soon as i got the hang of it i had no problems. I was aving my work on my documents.

27/3/09

I was saving my frames as png files. The frame raate i was aiming for was bigger than what i expected. Today though i was just continuing my animation.

30/3/09

The final size of my animation is 205 kb. The difficulties i encountered were pretty harsh. Some of them are; using the program itself, how to export the bitmap, where to export it to, how to upload videos to blogger. That is basically the major problems i had with this animation assignment.

31/3/09

Today was the day to do finishing touches and seeing if the animation works.

Finally it works.!!

My Sun

Gingerbread man

8 Clubs

Basically this is my creation....



Create 8 of clubs in Paint.


I saved my work first as a 24 bit map and then as a monochrome.


The file size of these files are:

• 24 bit map : 7.56KB



• monochrome: 180KB

Why do you think there is a difference in the file size?

The 24 bit map uses a wide variety of colours whereas monochrome uses just black and white so that is why the 24 bit map is the largest one.

The icons of Paint

Select

The select is the anti free-form select because this makes a selection of a picture in a rectangular shape.




Eraser/Colour Eraser

The eraser basically erases your mistakes as on a image or text.




Fill with colour

Fill with colour means to fill a gap with your wanted colour in your wanted spot.




Pick colour

For this one you can basically pick the colour you desire.




Magnifier


The magnifier makes the picture bigger. You can also use the magnifier to erase. What you do is you click the eraser and then click the magnifier and your eraser turns bigger and it saves time erasing with a small rubber.


Pencil

The Pencil draws whatever you would like it to draw, but you control it via your mouse.


Airbrush

The airbrush is basically a brush but it is lifted in the air and painted.

Text

For text you would have to insert the box where you would want writing and then you can put your text.


Line

Line is basically drawing a simple line in however way you want it to.


Rectangle

A rectangle is a recatngle drawn on paint.

Digital Art............Real Art

Digital Art is a term applied to contemporary art that uses the methods of mass production or digital media. Digital Technology has converted to traditional activities such as painting, drawing and sculpture while new forms, such as net art, installation art and virtual reality have been recognised in artistic practises.



1. Is digital art a valid form of art?

Digital art commonly refers to art created on a comptuer in digital form.

2. What are some advantages that digial paint and draw programs offer over the traditional methods(canvas and paint).

On the canvas you can turn or twist your paintbrush whichever way yo would like ot to. You can also change colours as you wish.



3. What skills must a digital artist possess to create great digital art?

The skills a digital artist would possess to create a great digital artwork is a steady hand and also a creative and imaginary mind.

Digital Media

Monday 9 February 2009



1. How many forms of digital media surrounds us?

Some forms of digital media that surround us are:

• The Internet



• Digital Television



• Cellphones



• compact disc



• e-book
  

2. What number system is digital media based on? What two digits are used to code all digital data?

Digital data is based on Binary numeral system and the 2 digits are 0 and 1.

3. What is a bit? What is a byte?

The terms bit and byte are common in computer networking. Both terms refer to digital data transmitted over a network connection. A byte is the memory capacity of a typical personal computer that runs from millions to billions of byte.

4. What is "sampling rate"? Find an image from that explans how sampling works.

Sampling rate determines the sound frequency range which can be represented in the digital waveform.

5. How does colour depth or bit depth effect the appearance of an image? Find some images to illustrate the effect.

Higher colour depth or bit depth gives a broader range of distict colours.

6. Colour depth effects both still and video digital media. Sampling rate only effects video but not still media. Can you explain.

The difference between colour depth and sampling rate is that sampling rate doesn't have the effect to video digital media. The reason for this is that colour depth has more of a variety.
