This document discusses two processes for abstracting information called cats and dogs. Cats involves ignoring unnecessary details while dogs involves identifying common patterns across multiple examples. It instructs groups to make an image puzzle requiring abstraction to solve, similar to the example but more difficult to determine the subject. The puzzle should follow the dogs process of identifying patterns across multiple internet images with unnecessary details removed.

Abstract expressionism
This slideshow was created as an introduction to a Year 9 unit on Abstract Expressionism, it was designed as a starting point for further research into specific artists of the movement and its wider influences. It was also designed as a starting point into a practical exercise recreating the 'sentiment' of AE without necessarily reproducing the 'methods'. It needs editing.
SDN Abstractions
The document discusses the need for abstractions in networking to simplify network control and management. It argues that networking currently lacks fundamental abstractions, unlike other fields like programming. Three key abstractions are needed: 1) a flexible forwarding model, 2) a state distribution abstraction through a global network view, and 3) separating detailed configuration. These abstractions form the basis of Software-Defined Networking (SDN) and help address its scalability and evolvability. A Network Operating System (NOS) is also proposed to manage the distributed state and communicate with forwarding elements.
Year 9 Natural Forms boards
The document provides guidance for a GCSE art project on natural forms, outlining the assessment objectives to research artists in different media, experiment with materials, document ideas and observations, and create a final piece making connections to artists. It includes examples of artists who work with natural forms in mono-chrome photography, painting, and printmaking and briefly describes their approaches.
Oil Pastel Technique
Oil pastels can be used in a variety of techniques including stenciling, blending, impasto, hatching and cross-hatching, parallel brush strokes, using fragmented colors, and scratching. The stencil technique involves using oil pastel as a backdrop covered by an ink wash, watercolor, or diluted acrylic paint, allowing the pastel to show through. Blending involves mixing colors using fingers, stumps, or solvents. Impasto creates thick, dense lines that bring out texture and intensity. Hatching and cross-hatching underline relief and create varied hues and textures.
Abstract expressionism
Abstract Expressionism was a mid-20th century art movement centered in New York City. Artists applied paint forcefully and non-geometrically to large canvases to express inner emotions and feelings. There were two main techniques - action painting involving dripped and splattered paint, and color field painting using solid fields of color. Pioneering artists included Jackson Pollock, famous for his drip paintings, Willem de Kooning, and Mark Rothko known for his blocks of color. Abstract Expressionism emphasized individual expression and made New York a new center for art.
Pseudocode
This document introduces pseudocode, which is a non-programming language used to design the logic and flow of a program before writing the actual code. It discusses common pseudocode structures like input/output, conditional statements, loops, and cases. Examples are given for how operations would be written in pseudocode versus actual programming languages like C# and Pascal. The document provides an assignment to write pseudocode that gets a number from the user and prints a message depending on if the number is less than or greater than 7.
Excel =if function
This document contains an IF statement formula that tests if the value in cell A2 is equal to 4, and will return the text "Value is four" if true, or "Value is not four" if false. The formula checks if the condition A2=4 is true or false, and returns one of two results based on that evaluation.

What is binary and why do we use it?
The document discusses binary numbers and how to convert between binary and decimal representations. It explains that binary uses only two digits, 0 and 1, and the place value of each digit determines its weight. To convert binary to decimal, you multiply each binary digit by its place value and sum the results. It provides examples of converting individual numbers between binary and decimal formats and describes how to perform the conversions using Excel functions like SUM(), INT(), and MOD().
Introduction to touch develop

It contains information about text, number, integer, real, date/time, and boolean fields that can be used in a database. Examples of validation include checking for a minimum height of 11.7 metres and verifying a date is in the correct format of 31st April 2012.
Databases 101
This document discusses databases and their purpose. It defines a database as a collection of records with fields of different data types like text, numbers, dates and booleans. It explains that databases are used to store and organize information in an structured way. Database design involves defining records, fields and field types. Validation and verification help ensure data accuracy. Relational databases differ from flat files in how data is structured and connected. Examples of database fields for student records are given to illustrate concepts.
Kodu controls
The document provides instructions for creating a countdown timer, spawning enemies, and a Kodu challenge to make a game with those elements. It explains how to create a 'referee' object to track time remaining, program it to subtract one second each turn from the start time. It also describes how to create an enemy, make it 'creatable', and program a spawning object to create enemies using a timer. The challenge is to make a game with a score, timer, spawning enemies, objectives, and clear win/lose conditions in an interesting world.
Pascal names and types
This document discusses variables, assignment, and types in the Pascal programming language. It provides an example program that asks the user to input a number between 1 and 99, analyzes their "personality" based on that number, and ends the program.

4) A challenge to write a Fahrenheit to Celsius temperature converter program in Python.
Thinking about your project
This document provides advice for choosing a project for COMP 4. It notes that managing a complete IT project from start to finish is a unique opportunity, but that such projects are often not fun due to a lack of real-world expectations, underestimating paperwork, feature creep over time, and poor time management rather than technical problems. It recommends choosing a complex project that interests the student and includes advanced algorithms, data structures, classes, mathematics, or technologies like simulations, portable devices, communication protocols, or image processing. The project should address a real problem and have a real end user.
The rail fence
The document discusses the rail fence cipher technique for encryption and decryption of text. It explains that the rail fence cipher arranges the characters of a plaintext message in a diagonal pattern, alternating between moving down and up in rows. It also uses two counters, one starting at the beginning and looping once, and the other starting after the first and looping to the end, to encrypt the message by reading down the columns.
Lesson 1
The document discusses programming concepts like variables, branching, and looping. It then introduces Scratch, a programming environment where users can create animations using sprites. It provides step-by-step instructions on how to program a cat sprite in Scratch to point towards and move towards the mouse pointer.
Rsa encryption
Public key cryptography uses a pair of keys - a public key for encryption and a private key for decryption. The keys are generated as follows:
1) Choose two prime numbers and multiply them to get n
2) Calculate φ(n) as (p-1)(q-1)
3) Choose a public key k that is relatively prime to φ(n)
4) Calculate the private key j using k*j=1 (mod φ(n))
To encrypt a message P, compute E=P^k (mod n). To decrypt, compute P=E^j (mod n).
Server side scripts
Server-side scripts allow for dynamic web page generation and user interaction by running programs on the server. Client-side form inputs are sent to the server as name-value pairs via GET or POST requests. Server-side programming/scripting languages like PHP then generate HTML dynamically based on the form values submitted. For example, a form using the GET method sends user inputs in the URL, and a PHP script can echo those values on the resulting page.
Revision topic 1 sensors and control
Sensors measure physical properties and translate them into analog electrical signals. Common sensors detect light, sound, temperature, pressure, acceleration, motion, and heat. Analog signals have a continuous range of values, while digital signals are discrete on/off values. To use sensor readings in computers, analog signals must be converted to digital. Monitoring involves simply measuring something, like the weather, while control uses feedback - sensors provide measurements to a computer program that sets control values to influence a motor or actuator.

The document discusses getting an antidote from Mr. Macleod's computer in order to save someone now. It also mentions Mr. Macleod's computer security systems and encryption. The document suggests explaining how the computer's security was overcome to access the needed antidote.
Hashing
Hashing involves using an algorithm to generate a numeric key from input data. It maps keys to integers in order to store and retrieve data more efficiently. A simple hashing algorithm uses the modulus operator (%) to distribute keys uniformly. Hashing is used for file management, comparing complex values, and cryptography. Collisions occur when different keys hash to the same value, requiring strategies like open hashing, closed hashing, or deleting data. Closed hashing supplements the hash table with linked lists to store colliding entries outside the standard table.

Gm names n stuff
This document discusses key concepts related to URLs and the internet infrastructure. It defines terms like internet, intranet, URL, URI and protocol. It explains the components of a URL like the scheme, host and path. Traceroute is introduced as a tool to trace the path a request takes. The roles of organizations like ICANN, IETF and registrars in managing domain names and internet resources are overviewed at a high level. Steps for registering a domain name with a registrar are outlined. The difference between a URI and URL is that a URI identifies a resource while a URL provides location information to access that resource.

Abstraction - Year 9
- 1. What are these paintings about?
- 2. What are these photos of?
- 3. How did you do that? Cats: You ignored, you removed the unnecessary detail. Dogs: You identified the patterns, the things that all the photos had in common. We call these two processes ‘Abstraction’
- 4. Working in your groups Make a puzzle, using images from the internet – that require abstraction to solve. Make the puzzle like the group of pictures that you’ve just seen, but make it harder to work out what the subject is.
