Scrath Tutorials - Keep-Score


In this example of Scratch, the score increases by 1 point every time the shark touches the crab.

Scratch Tutorials - Whirl



In this Scratch tutorial, the cute little monkey sprite whirls.... whatever that means. Well, you can see what it does on the two pictures of the monkey above:-)

Scrath Tutorials - Animate It, Change Colour, Glide and Follow The Mouse


Yeah, so above is another example of what you can do on Scratch :-)
I've made the sprite change costume, so it looks like it's walking, and as it walks, it changes colour. When i press the space button, it glides to different points, and when the green flag in top right corner is clicked, it follows the mouse ;-)

Wireless broadband and Cable broadband

Broadband means speed and is a collective name given to a range of high speed internet connections that are normally switched on.

Wireless boradband is ten times faster than a dial-up connection plus it is completly independent of your phoneline. You connect via a small outdoor antenna to a network of small community-based radio repeater stations. Upload speeds are typically half the download speed and if the service uses a satellite feed to connect back to the internet there may be some limitations such as not being able to use video conferencing tools.

Cable broadband is broadband delivered via a cable and is only available for people with cable service in their area. Cable broadband is optic fibres that offer an excellent way of getting online, watching television and using the telephone.

The World of Multimedia

There are many types of multimedia that we use in our daily lives. Mobile phones are used everyday to communicate with friends and family. Computers are essential because we can find information on anything and this is helpful when doing research and other schoolwork. Also, we can communitcate with other people using the computer through email and chat and computers are therfore used constantly.
It would be hard for people nowadays to live without a computer or mobile phone, and I believe that we would have a hard time finding information and communicating with friends and family. In my opinion, phones and computers will become more like a part of life in the future, and it will become harder for us to live without these.
The video on future directions seems pretty reliable to me. There are already some things that reminds me of those items in it. They are faster, easier and portable. I cannot see any any disadvantages in these future items.

RSS Feeds

1) Define RSS Feeds:
RSS stands for Really Simple Syndication. It is a format that distributes news and other web content. A feed is when you put that content into RSS and send it to other people or websites.

2) What goes in the feed?
Audio, music, texts, videos and images. The feed contains a list of items that is identified by a link to the content on your site.

3) What can a feed do for you?
It allows you to see content without going to the website. Once you subscribe, the content comes to you.

4) How is a feeds different from email?
Feeds provide more information than an email. Emails are personal and meant for only you to read, however, a feed is not personal and can be read by anyone.

5) How do people read feeds?
To read RSS feeds, you send out the content and subscribers read it using newsreaders.

6) How do people find the feeds you want to subscribe to?
By using search-engines.

Broadband ?!

1. What is broadband?
Broadbans is a type of data transmission in which a single medium can carry several channels at once. Broadband technology can transmit data, audio, and video all at once over long distances.

2. What units are used to measure bandwidth?
Bandwidth is measurred in megabits.

3. How much faster is broadband than dial up?
Broadband is about 40 times faster than dial up.

4. What are the speeds that broadband operates at compared to dial up?
A broadband connection transfers information at a rate of at least 2 megabits per second, a standard narrowband transfers info at the rate of 56 kilobits per second.

5. What are some of the advantages of using a broadband connection to download something like a video compared to dial up?
An advantage is that it provides tru media such as video, voice and data without the delay a narrowband incurs.

SYNOPSIS - Term 2 assessment

In this terms assignment we are asked to do a video on a topic of our choosing. Rena, Andy and I decided to do ours on chocolate... yeah, I know it's a weird topic, but we didn't have any better ideas. It's aimed at, well, everybody, and teaches us facts about chocolate that we might not have known about before.

We have included an intro, history of chocolate, Aztecs and their relation with chocolate, slave labour, Nutritional information, the states of chocolate and the outro.
By the way, I'm doing history of chocolate and the outro :-)

Buying a DIGITAL CAMERA




I want a camera so that I can take pictures at important events such as birthday parties, etc. so I have memories of that day. The resolution should be 4 mega pixel or more.



This camera is what I need, when taking pictures at events with family or friends, because it has optical view finder, light weight, very sharp photos and fast and responsive to start-up and shoot, and so it is easy to take pictures with it.


This Camera offers photographic performance and easy-to-use features and controls. 10 effective mega pixels, a 5x Zoom-NIKKOR lens, Optical Vibration Reduction, Image Stabilization technology, and 15 user-friendly scene modes, the COOLPIX S560 is the perfect camera for photographers looking for a compact, lightweight camera that is user-friendly with great creative power, and that is what I would like to have.


A card reader would be useful, because it can then be used as a USB, and that would make it easy to transfer images from the camera to the computer.





Image File Types

Here's an explanation on some file types:

GIF files:

This is one of the most common image format. It encodes static bitmap images. In a bitmap image, the image file has to define the exact color of every pixel in the image. In a GIF image, the number of colors is reduced to 256 and then "runs" of same-color pixels are encoded in a color + number-Of-Pixels format. This makes a GIF file great for storing drawings that have lots of same-color pixels.

JPEG files:

This file is, like the GIF format, the most commonly used image format. It uses more complex techniques to compress images, where the colour of every pixel is different.

Animated GIF files:

An animated GIF file is a number of GIF files bonded together and displayed one after another. However, the size of the file is the sum of the GIF files used to create the sequence, and that can add up quickly.

MPEG files:

An MPEG file is like a JPEG file: it uses a complex algorithm like a JPEG file does, trying to eliminate repetition between frames to significantly compress video information. In addition it allows a soundtrack. Because a typical sequence has hundreds or thousands of frames, file sizes can still get quite large.

Shockwave files:

Shockwave files provides a vector-based animation capability. Instead of specifying the color of every pixel, a Shockwave file specifies the coordinates of shapes as well as the color of each shape. Shockwave files can be extremely small. They also provide soundtracks and animation. Because they are vector-based, you can enlarge the image and it will still look great.



What is a vector based image and how is it different to a bitmap based image?

Vector images are mathematically-based. All lines, shapes, etc. of a vector-based image are independent of one another.
Vector-based images are usually created and edited in "draw" or "illustrate" programs such as Adobe Illustrator. They have smooth edges and create curves or shapes. Vector-based images are good for precise illustrations, but are not as good for photorealistic images. They are easily scalable, due to their use of mathematic formulas.

Bitmap images, also referred to as raster images, are pixel-based. This means that location and color information about the image is stored in individual pixels within a grid.The information stored in a bitmap image regarding pixel location and color is what forms the image. Bitmap images are edited at the pixel level; in other words, the color of any one pixel can be changed.

ANIMATION ASSESMENT IN IST!!! DIARY ENTRY!!!

27/3/2009



Our first IST assessment this year. We have to create an animation promoting our future house website. I'm in Coolock house, and I planned to make my animation on Gimp, because it's the easiest paint application for me. I want to do a clover walking to a party in Coolock house.




29/3/2009

Today I started making my animation. I saved it as a xcf file while making it. I made one image, then duplicated, then made another image, and so on when creating the animation. I saved my frames as Gimp formats. The frame rate was 100 milliseconds.



31/3/2009



I finished my animation today in class, but I still need to uploade it to my blog. I hope I'm gonna do it right!



3/4/2009



I tried to upload the animation to my blog, but it doesn't want to upload. It says something is wrong...



3/4/2009



Now I know why it didn't upload my animation! It was because it was a GIF image, and I needed a AIF image! Now it worked! Thanks to Serena and my dad of course, because I didn't know why it didn't want to upload... THANK YOU SO MUCH SERENA! and my dad of course :-)

Difficulties and advantages when making the picture using Word:


When I wanted to draw the interlocking, I had diificulties finding tools that could do it. However, the rings were made easily because there was a ring shape in Autoshapes, and I could quickly get the right line and fill colour.

Dgital Art

· A discussion point. “Is digital art a valid form of art?”



Yes


· What are some of the advantages that digital paint and draw programs offer over the traditional methods (canvas and paint).



Background colours, frames, cut and paste, crop.


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



A digital artist must know what each different tool in a drawing program can do, and how to use the programs, to create great digital art.

Digital Media

· List how many forms of digital media surround us.


Digital telvision, digital video, internet, video games, and World Wide Web (www)




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




Digital data is based on Binary numbers. 0 and 1 are the two digits to code all digital data.



· What is a bit? What is a byte?



A bit is a single numeric value, either 1 or 0, a byte contains 8 bits.



· What is “sampling rate”? Find an image that explains how sampling works (Wikipedia is a good resource here…you can place these images in your blog)



A sampling rate is a grah that shows the amount of a sample per second.






courtsy of ww.en.wikipedia.org/wiki/Sampling_rate



· How does Colour Depth (Color Depth) or bit depth effect the appearance of an image? Find some images to illustrate the effect.



Colour depth affects the apperance of an image by altering the colour quality depending onthe amount of bytes or bits in that particular image. For example if you have one or two bits in an image you will only have a monochrome coloured image. Whereas is you have an image with more bytes you will get a better quailty image with 64 bytes being the largest so far.



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



Sampling rate only affects video as it takes the sample per second, a video is a moving image and therefore the sampling rate would take the images per second. However colour depth only affects still and video digital media. Nothing is produced in still images and therefore a sampling rate is not affected.
