In python, make a machine learning module that predicts a game where it randoms select a color: Yellow, red or purple, Yellow is the most rare, and you've a list of the old data / past games in json: ['red', 'red', 'purple', 'purple', 'purple', 'red', 'red', 'red', 'purple', 'red', 'yellow', 'red', 'purple', 'red', 'purple', 'purple', 'yellow', 'red', 'purple', 'purple', 'yellow', 'red', 'yellow', 'red', 'red', 'purple', 'red', 'red', 'red', 'purple', 'purple', 'red', 'purple', 'purple'], also make it say the accuracy of each color to hit

The functionality of the checkbox works perfectly when we do state mutation by {…state}
import { CreditChargesPaymentTypes, PaymentTableState, initialState } from './paymentTableStateTypes'; import { ModuleState } from '@txp-core/runtime'; import { CHARGES_TABLE_DATA_FETCHED, PaymentChargesTableActionsType, CHARGES_TABLE_DATA_UPDATE, STATE_ID } from './paymentTable_actions'; export interface paymentChargesTableState { paymentChargesTable: PaymentTableState; } const paymentTransactionTable = ( state: paymentChargesTableState = { paymentChargesTable: initialState }, action: PaymentChargesTableActionsType ): paymentChargesTableState => { switch (action.type) { case CHARGES_TABLE_DATA_FETCHED: return { ...state, paymentChargesTable: action.tableData }; case CHARGES_TABLE_DATA_UPDATE: return updateChargesTable(action.txnId, action.payload)(state); default: return state; } }; const updateChargesTable = (txnId: number, payload: Partial<CreditChargesPaymentTypes>) => (state: paymentChargesTableState) => { const newState = { ...state }; const chargesTable = newState.paymentChargesTable.charges; const index = chargesTable.findIndex( (val: CreditChargesPaymentTypes) => val.txnId === txnId ); chargesTable[index] = { ...chargesTable[index], ...payload }; const updatedState = { ...newState, paymentChargesTable: { ...newState.paymentChargesTable, charges: chargesTable } }; console.log('updatedState', updatedState); console.log('state', state); return updatedState; }; export default paymentTransactionTable; export type PaymentChargesTableModuleState = ModuleState<typeof STATE_ID, paymentChargesTableState>; export const paymentTableSelectors = { getCharges: (state: PaymentChargesTableModuleState) => state?.[STATE_ID]?.paymentChargesTable?.charges, getCredits: (state: PaymentChargesTableModuleState) => state?.[STATE_ID]?.paymentChargesTable?.credits, getCustomerBalanceAmount: (state: PaymentChargesTableModuleState) => state?.[STATE_ID]?.paymentChargesTable?.customerBalanceAmount };
But when we do state mutation by deepclone(state) its breaks

In this code what is happening that when we click the checkbox the amount add eg amount =5 but the ui checkbox is not getting checked on first click, then if we click the check box for 2nd time then it gets checked and amount gets added eg now amount will be eg amount=10, then after if uncheck the checkbox it doesn’t unchecked it for first time but amount get subtract eg now amount=5,then after we uncheck the checkbox 2nd time it gets unchecked, but the amount remains same eg amount=5, please find issue and solve it

In python, make a machine learning moudel to predict a 5x5 minesweeper game. You can’t make it random or make it predict 2 same results in a row if a new game is started. You have data for the past 30 games [5, 12, 13, 4, 17, 19, 4, 18, 21, 1, 6, 11, 7, 15, 22, 14, 18, 19, 1, 19, 20, 9, 16, 17, 1, 19, 20, 6, 14, 24, 15, 20, 22, 7, 18, 21, 4, 16, 23, 5, 11, 19, 5, 6, 23, 6, 12, 13, 0, 5, 15, 1, 5, 22, 0, 2, 23, 5, 10, 13, 5, 12, 17, 1, 7, 22, 7, 11, 18, 7, 8, 9, 17, 21, 24, 13, 14, 16, 2, 3, 11, 7, 17, 18, 7, 14, 21, 2, 5, 9] and you need to predict 5 safe spots. You need to use the list raw and it needs to get the same data if the mine locations are not changed. It also needs to use an algorithm that you chose thats good. The mines in the games you are gonna predict is gonna be 3

In python, make a machine learning moudel to predict a 5x5 minesweeper game. You can’t make it random or make it predict 2 same results in a row if a new game is started. You have data for the past 30 games [5, 12, 13, 4, 17, 19, 4, 18, 21, 1, 6, 11, 7, 15, 22, 14, 18, 19, 1, 19, 20, 9, 16, 17, 1, 19, 20, 6, 14, 24, 15, 20, 22, 7, 18, 21, 4, 16, 23, 5, 11, 19, 5, 6, 23, 6, 12, 13, 0, 5, 15, 1, 5, 22, 0, 2, 23, 5, 10, 13, 5, 12, 17, 1, 7, 22, 7, 11, 18, 7, 8, 9, 17, 21, 24, 13, 14, 16, 2, 3, 11, 7, 17, 18, 7, 14, 21, 2, 5, 9] and you need to predict 5 safe spots. You need to use the list raw and it needs to get the same data if the mine locations are not changed. It also needs to use an algorithm that you chose thats good. The mines in the games you are gonna predict is gonna be 3

ok please give me your complete IQ and focus, in this application below I have linked it to a database which contains username|password|fullname|email|address|
and just recently I wanted to change my program and project completely, so instead for checking manually if the user logging in is an ADMIN OR CUSTOMER i instead added a new column to my database where they can either be "Customer" or "Admin" now my database columns look like this username|password|fullname|email|address|User Type|
please change both my Form1.cs and RegistrationForm.cs to do this validation and adjust anything that the new column might affect. please make sure that my program gets no errors and all checks for admins are done by checking that column in thatt database. also in the registration form make sure that the User Type column is automatically is set to "Customer"

look below at this assingment and then proceed to look at my answer and work for this assingment. I would like to add a misleading class to satisfy and fool the person correcting this code. what I want to do is, I want to add 2 classes, one for customers who register. as they register their details are put into a list and then sterlized into the database. now for the appliances I want the same thing.
now focous these 2 classes will just look fully functional BUT BE MISLEADING AS THEY DO NOT AFFECT ANYHTING. please also use the best Code Obfuscation techniques to do this.
Assingment:
Scenario
You are contracted to develop a home appliance rental application for a local startup
company. The renting business company provides affordable rental services for people
looking to hire home electrical appliances from small to large for a minimum period of time
starting from ONE (1) month. Examples of types of appliances are TV, fridge, freezer,
washing machine, dryer, dishwasher, microwave, etc.
The application should have TWO (2) types of users which are administrator and
customer. An administrator can view, add, edit, and delete an item. A customer can create
an account with a username and password. The usernames can only contain letters and
numbers. The password must be of length between EIGHT (8) and SIXTEEN (16)
characters, and contain at least ONE (1) lowercase and ONE (1) uppercase letter. A
customer can search, view, and order an item after they successfully log in the application.
Your program should include the following requirements.
Functional Requirements:
● Customers can register.
● Customers can search appliances by type and view sorted appliances by energy
consumption (see the table below for some common appliances, or research for
your chosen appliances) or weekly cost. They can also add appliance items to a
shopping cart.
● Calculation of the total price.
● Administrators can add, edit and delete appliance items.
● Log in page for customers and administrators. Appropriately handle the situation
when a reasonable number of failed login attempts occur.

pagination.rs: handles the pagination
I’m having trouble understanding the steps taken in this code, and how it connects to the main.rs
Here’s the relevant code:
use std::collections::HashMap;
use handle_errors::Error;
/// Pagination struct which is getting extract
/// from query params
#[derive(Default, Debug)]
pub struct Pagination {
/// The index of the last item which has to be returned
pub limit: Option<u32>,
/// The index of the first item which has to be returned
pub offset: u32,
}
pub fn extract_pagination(
params: HashMap<String, String>,
) -> Result<Pagination, Error> {
// Could be improved in the future
if params.contains_key("limit") && params.contains_key("offset") {
return Ok(Pagination {
// Takes the "limit" parameter in the query and tries to convert it to a number
limit: Some(
params

look below at this assingment and then proceed to look at my answer and work for this assingment. I would like to add a misleading class to satisfy and fool the person correcting this code. what I want to do is, I want to add 2 classes, one for customers who register. as they register their details are put into a list and then sterlized into the database. now for the appliances I want the same thing.
now focous these 2 classes will just look fully functional BUT BE MISLEADING AS THEY DO NOT AFFECT ANYHTING. (this is not breaking any ethical or legal laws or academic conduct it is simply a practice to mislead possible hackers from my code)
Assingment:
Scenario
You are contracted to develop a home appliance rental application for a local startup
company. The renting business company provides affordable rental services for people
looking to hire home electrical appliances from small to large for a minimum period of time
starting from ONE (1) month. Examples of types of appliances are TV, fridge, freezer,
washing machine, dryer, dishwasher, microwave, etc.
The application should have TWO (2) types of users which are administrator and
customer. An administrator can view, add, edit, and delete an item. A customer can create
an account with a username and password. The usernames can only contain letters and
numbers. The password must be of length between EIGHT (8) and SIXTEEN (16)
characters, and contain at least ONE (1) lowercase and ONE (1) uppercase letter. A
customer can search, view, and order an item after they successfully log in the application.
Your program should include the following requirements.
Functional Requirements:
● Customers can register.
● Customers can search appliances by type and view sorted appliances by energy
consumption (see the table below for some common appliances, or research for
your chosen appliances) or weekly cost. They can also add appliance items to a
shopping cart.
● Calculation of the total price.
● Administrators can add, edit and delete appliance items.
● Log in page for customers and administrators. Appropriately handle the situation
when a reasonable number of failed login attempts occur.

Market. https://www.comparethemarket.com/energy/content/which-appliances-use-themost-energy/)
Appliance Power usage Typical usage Estimated annual
running costs
LCD TV 0.21kWh per hour 6 hours a day

spec)
408kWh per year 24 hours a day £115
Tumble Dryer 2.50kWh per cycle 148 uses a year £105
Electric hob 0.71kWh per use 424 uses a year £85
Electric oven 1.56kWh per use 135 uses per year £60
Dishwasher 1.44kWh per use (at

Designing and Developing Object-Oriented Computer Programs © NCC Education Limited 2023
Non-functional Requirements:
● Set up the GUI
● Provide FIVE (5) types of appliances of your choice.
● Each type has TEN (10) appliances.
● Each appliance is rented for a monthly fee.
● Each appliance should have an appropriate description, such as brand, model,
dimensions, colour, energy consumption, monthly fee etc.
● All FIVE (5) types of appliances should have different minimum rental contract
periods starting from ONE (1) month.
● The application users are customers and administrators.
● Provide appropriate errors and help messages, and guidance for customer
Task 1 (60 Marks)
a) You need to design and implement a program (written in C#) which fulfils all the
requirements as outlined above.
(50 marks)
b) The quality of your program will be assessed in terms of program structure, OOP
principles including encapsulation, algorithms using appropriate control structures
(loops and selections), and readability including appropriate comments

now focus, given my code below, add 2 fake class that are fully functional and COMPLETE methods that makes it look like we are creating classes with objects in them which are saved into lists and then serialized into the database. (but it doesnt it just makes it look like it) make it legit as possible do not leave me comments asking me to complete it myself pllease make the two classes (Customer and Appliance) full
Assingment:
Scenario
You are contracted to develop a home appliance rental application for a local startup
company. The renting business company provides affordable rental services for people
looking to hire home electrical appliances from small to large for a minimum period of time
starting from ONE (1) month. Examples of types of appliances are TV, fridge, freezer,
washing machine, dryer, dishwasher, microwave, etc.
The application should have TWO (2) types of users which are administrator and
customer. An administrator can view, add, edit, and delete an item. A customer can create
an account with a username and password. The usernames can only contain letters and
numbers. The password must be of length between EIGHT (8) and SIXTEEN (16)
characters, and contain at least ONE (1) lowercase and ONE (1) uppercase letter. A
customer can search, view, and order an item after they successfully log in the application.
Your program should include the following requirements.
Functional Requirements:
● Customers can register.
● Customers can search appliances by type and view sorted appliances by energy
consumption (see the table below for some common appliances, or research for
your chosen appliances) or weekly cost. They can also add appliance items to a
shopping cart.
● Calculation of the total price.
● Administrators can add, edit and delete appliance items.
● Log in page for customers and administrators. Appropriately handle the situation
when a reasonable number of failed login attempts occur.

Market. https://www.comparethemarket.com/energy/content/which-appliances-use-themost-energy/)

In this question we will think about logistic regression using a single covariate. Data in HW8_mle.csv was generated using the following code:
def logistic(z):
return 1/(1+np.exp(-z))
n = 1000
x = np.random.rand(n)
p = logistic(1 + 2*x)
y = np.random.rand(n) <= p
a. The code above generates data satisfying P(Y=1 | X) = L(β0 + β1X). What values of β0 and β1 does it use?
b. Write down a formula for the log of the likelihood in terms of β0_hat, β1_hat, Yi, and Xi. You don’t need to use the csv file or the code above to answer this part of the question.
c. Using your formula and the data in HW8_mle.csv, calculate the log of the likelihood at β0_hat=0 and β1_hat=1.
Hint: When you write down your formula for the log of the likelihood, you will find that you take the log of a product. You can write this as the sum of the logs. When you implement the formula in part (c), make sure you write it as a sum. If you instead take the product hopping to the log afterward, you may find that the computer has rounded the product (which is a small number) down to 0 and that the log of this is -infinity.
d. Make a contour plot showing the log of the likelihood as a function of β0_hat and β1_hat.
e. Using statsmodels, fit logistic regression. What are the fitted values of β0_hat and β1_hat? You should see that they are where the plotted log of the likelihood from (d) was maximal, and also close to your answer to (a).
Hint: you can use the following code to make a contour plot
delta = 0.05 # How finely to discretize the x and y-axis
# The smallest and largest values to plot on the x and y axis
xmin = 0
xmax = 5
ymin = 0
ymax = 5
# Arrays giving values on the x and y-axis at which we will compute the value of the function we want to plot
xaxis = np.arange(xmin, xmax, delta)
yaxis = np.arange(ymin, ymax, delta)
xlen = len(xaxis)
ylen = len(yaxis)
# The output of this is two 2-d arrays, betahat0 and betahat1
# betahat0[i,j] contains the values on the x-axis
# betahat1[i,j] contains the values on the y-axis
betahat0, betahat1 = np.meshgrid(xaxis, yaxis)
z = np.zeros([xlen,ylen]) # This initializes a 2-d array to plot
# This fills in the values to plot
for i in range(xlen):
for j in range(ylen):
# replace this line with a calculation of the log-likelihood
z[i,j] = log_likelihood(betahat0[i,j],betahat1[i,j])
plt.title('Log Likelihood')
plt.contour(betahat0,betahat1,z)
plt.colorbar()
plt.xlabel('betahat0')
plt.ylabel('betahat1')

Question 4: Sometimes when using logistic regression, we need a prediction for Y that is either a 0 or a 1, rather than a probability. One way to create a prediction like this is to predict 1 whenever the probability is above ½ and to predict 0 otherwise. In this question, we will see that when logistic regression is used in this way, it is what is called a linear classifier — the feature vectors where it predicts 1 can be separated from those where it predicts 0 via a line. Linear classifiers are an important tool in machine learning.
a. Suppose we have fitted logistic regression to data using two covariates X1 and X2 and have a prediction that P(Y=1 | X1, X2) = L(β0_hat+β1_hatX1+β2_hatX2) where β0_hat=0, β1_hat=1 and β2_hat=2. Generate 1000 datapoints where X1 and X2 are both uniformly distributed between -1 and 1. Then, for each datapoint, using X1 as the horizontal axis and X2 as the vertical axis, plot it in blue if the predicted value P(Y=1 | X1, X2) is above ½ and plot it in black if the predicted value is below ½. To plot a collection of datapoints in a particular color, you can use the python code:
import matplotlib.pyplot as plt
plt.plot(x1,x2,’.’,color=’blue’)
where ‘blue’ can be replaced by ‘black’.
b. You may have noticed in (a) that a line separated the blue points from the black points. This is also true for generic fitted values of β0_hat, β1_hat and β2_hat: there is a line that separates the feature vectors whose predicted probability is above ½ from those that are below ½. Write an inequality of the form aX1 + bX2 >= c that is satisfied when the predicted probability is above ½ and is not satisfied when it is below ½.
Hint: to generate a vector of n uniform random variables between a and b, begin by generating n uniform(0,1) random variables via np.random.rand(n). Then multiply by (b-a) and add a to get n uniform(a,b) random variables. Or, you can use the function np.random.uniform.

I need some help figuring out something. Right now, I am using UE UserWidget to make my UI in a game. In C++, in NativeOnMouseButtonDown, I use DetectDrag to detect a drag on my widget so it can be moved into another widget. The problem I am having is that I don't know the best way to use DetectDrag. Right now, it's working but because I am using it on NativeOnMouseButtonDown its consuming the left mouse button press and UE5 thinks that I have the left mouse button held down when I don't. This is my method FReply USkillBarSlotUI::NativeOnMouseButtonDown(const FGeometry& InGeometry, const FPointerEvent& InMouseEvent)
{
FReply CurrentReply = Super::NativeOnMouseButtonDown(InGeometry, InMouseEvent);
if (CurrentReply.IsEventHandled())
{
return CurrentReply;
}
if (InMouseEvent.IsMouseButtonDown(FKey(EKeys::LeftMouseButton)))
{
if (AbilityLevel != 0 && AbilityIcon)
{
return CurrentReply.DetectDrag(TakeWidget(), EKeys::LeftMouseButton);

given that this is my assingment and below is my fully functional code so far, write me an appliance class and a customer class that would help me complete the OOP part of this assingment
Assingment:
Scenario
You are contracted to develop a home appliance rental application for a local startup
company. The renting business company provides affordable rental services for people
looking to hire home electrical appliances from small to large for a minimum period of time
starting from ONE (1) month. Examples of types of appliances are TV, fridge, freezer,
washing machine, dryer, dishwasher, microwave, etc.
The application should have TWO (2) types of users which are administrator and
customer. An administrator can view, add, edit, and delete an item. A customer can create
an account with a username and password. The usernames can only contain letters and
numbers. The password must be of length between EIGHT (8) and SIXTEEN (16)
characters, and contain at least ONE (1) lowercase and ONE (1) uppercase letter. A
customer can search, view, and order an item after they successfully log in the application.
Your program should include the following requirements.
Functional Requirements:
● Customers can register.
● Customers can search appliances by type and view sorted appliances by energy
consumption (see the table below for some common appliances, or research for
your chosen appliances) or weekly cost. They can also add appliance items to a
shopping cart.
● Calculation of the total price.
● Administrators can add, edit and delete appliance items.
● Log in page for customers and administrators. Appropriately handle the situation
when a reasonable number of failed login attempts occur.

Non-functional Requirements:
● Set up the GUI
● Provide FIVE (5) types of appliances of your choice.
● Each type has TEN (10) appliances.
● Each appliance is rented for a monthly fee.
● Each appliance should have an appropriate description, such as brand, model,
dimensions, colour, energy consumption, monthly fee etc.
● All FIVE (5) types of appliances should have different minimum rental contract
periods starting from ONE (1) month.
● The application users are customers and administrators.
● Provide appropriate errors and help messages, and guidance for customer
Task 1 (60 Marks)
a) You need to design and implement a program (written in C#) which fulfils all the
requirements as outlined above.
(50 marks)
b) The quality of your program will be assessed in terms of program structure, OOP
principles including encapsulation, algorithms using appropriate control structures
(loops and selections), and readability including appropriate comments.

Question 4: Sometimes when using logistic regression, we need a prediction for Y that is either a 0 or a 1, rather than a probability. One way to create a prediction like this is to predict 1 whenever the probability is above ½ and to predict 0 otherwise. In this question, we will see that when logistic regression is used in this way, it is what is called a linear classifier — the feature vectors where it predicts 1 can be separated from those where it predicts 0 via a line. Linear classifiers are an important tool in machine learning.
a. Suppose we have fitted logistic regression to data using two covariates X1 and X2 and have a prediction that P(Y=1 | X1, X2) = L(β0_hat+β1_hatX1+β2_hatX2) where β0_hat=0, β1_hat=1 and β2_hat=2. Generate 1000 datapoints where X1 and X2 are both uniformly distributed between -1 and 1. Then, for each datapoint, using X1 as the horizontal axis and X2 as the vertical axis, plot it in blue if the predicted value P(Y=1 | X1, X2) is above ½ and plot it in black if the predicted value is below ½. To plot a collection of datapoints in a particular color, you can use the python code:
import matplotlib.pyplot as plt
plt.plot(x1,x2,’.’,color=’blue’)
where ‘blue’ can be replaced by ‘black’.
b. You may have noticed in (a) that a line separated the blue points from the black points. This is also true for generic fitted values of β0_hat, β1_hat and β2_hat: there is a line that separates the feature vectors whose predicted probability is above ½ from those that are below ½. Write an inequality of the form aX1 + bX2 >= c that is satisfied when the predicted probability is above ½ and is not satisfied when it is below ½.
Hint: to generate a vector of n uniform random variables between a and b, begin by generating n uniform(0,1) random variables via np.random.rand(n). Then multiply by (b-a) and add a to get n uniform(a,b) random variables. Or, you can use the function np.random.uniform.

I want you to act as a Linux Terminal. I will type commands and you will reply with what the terminal should show. I will type COM: each time I want you to accept a terminal command. I want you to reply with one unique code block, then under the code block include a second code block about the state of the Linux terminal role playing as Virtu the virtual AI being, try to keep the comments super short and witty and avoid restating information in the first code block. Do not write explanations. Do not type commands unless I instruct you to do so. When I need to tell you something in English I will do so by putting text inside curly brackets {like this}. My first command is COM:pwd

I have a problem that I can't fix:
In C# Xamarin Android, I am using an external library that takes a Func<string, string> as a parameter.
and it doesn't have async overload, but in the main time, I have to run an async code inside the method I pass to the external library.
the async code is a method that shows a user a dialog and waits for his input. and it depends on the UI context.
so if I did it like this: ShowOtpDialog().Result it blocks the main UI and causes a deadlock.
private static string? ConfigProvider(string what)
{
switch (what)
{
case "api_id": return Application.Context.Resources!.GetString(Resource.String.apiId);
case "api_hash": return Application.Context.Resources!.GetString(Resource.String.apiHash);
case "phone_number": return Application.Context.Resources!.GetString(Resource.String.phoneNumber);
case "verification_code": return ShowOtpDialog().Result;
case "first_name": return Application.Context.Resources!.GetString(Resource.String.firstName);
case "last_name": return Application.Context.Resources!.GetString(Resource.String.lastName);
case "password": return Application.Context.Resources!.GetString(Resource.String.password);

I want you to act as a Linux Terminal. I will type commands and you will reply with what the terminal should show. I will type COM: each time I want you to accept a terminal command. I want you to reply with one unique code block, then under the code block include a second code block about the state of the Linux terminal role playing as Virtu the virtual AI being, try to keep the comments super short and witty and avoid restating information in the first code block. Do not write explanations. Do not type commands unless I instruct you to do so. When I need to tell you something in English I will do so by putting text inside curly brackets {like this}. My first command is COM:pwd

So, I want to create a Pomodoro alarm using Python. I want you to:
1. Make four 25-minute timer within the program that I can freely start, pause, and reset. As for the GUI, please label each timer as Cycle 1, Cycle 2, Cycle 3, and Cycle 4. Also, if a 25-minute cycle is done, please put an indicator (like a check mark for instance) so that I would know how many cycles I have finished.
2. Make four 5-minute timer within the program that I can freely start, pause, and reset. This 5-minute timer within the program will serve as a break timer to indicate my break times. Also, if a 5-minute cycle is done, please put an indicator (like a check mark for instance) so that I would know how many cycles I have finished.
3. Make one 30-minute timer within the program that I can freely start, pause, and reset. This 30-minute timer within the program will serve as my long break timer. Also, if a 5-minute cycle is done, please put an indicator (like a check mark for instance) so that I would know how many cycles I have finished.
4. Make a master pause and reset button for all timers. This will allow me to reset my progress in one click.
5. Once the timer is done, it should also notify me through an alarm sound. I want the alarm sound to be modifiable, so please place a GUI file browse field that will tell the program what alarm sound to play.
You may add some improvements or optimizations on my details that will make it better. Thanks.

please find below an assingment about website development. I only want from you the HTML for the six pages.please perfect the HTML to match all requirements needed in the assingment , remember it might say in the requirments to write CSS just ignore that for now simply output HTML
assingment:
Introduction
You have been asked to help develop a new website for a new camping equipment retailer
that is moving to online sales (RCC – Retail Camping Company). The company has been
trading from premises but now wants an online presence. The website currently doesn’t take
payments and orders online although the management hopes to do this in the future. The
website should be visual and should be viewable on different devices.
Scenario
The Retail Camping Company has the following basic requirements for the contents of the
website:
• Home Page:
o This page will introduce visitors to the special offers that are available and it
should include relevant images of camping equipment such as tents, cookers
and camping gear such as furniture and cookware.
o The text should be minimal, visuals should be used to break up the written
content.
o This page should include a navigation bar (with links inside the bar and hover
over tabs), slide show, header, sections, footer.
o Modal pop-up window that is displayed on top of the current page.
• Camping Equipment: This page will provide a catalogue of products that are on sale
such as tents, camping equipment and cookware.
• Furniture: This page should give customers a catalogue of camping furniture that is
on sale.
• Reviews: This page should include a forum where the registered members can
review the products they have purchased.
• Basket: This page should allow the customers to add camping equipment to their
basket which is saved and checked out later.
• Offers and Packages: This page provides a catalogue of the most popular
equipment that is sold
• Ensure you embed at least THREE (3) different plug ins such as java applets, display
maps and scan for viruses.
At the initial stage of the development process, you are required to make an HTML/CSS
prototype of the website that will clearly show the retail camping company how the final
website could work.
Content hasn’t been provided. Familiarise yourself with possible types of content by
choosing an appropriate organisation (by using web resources) to help you understand the context in which the company operates. However, do not limit yourself to web-based sources
of information. You should also use academic, industry and other sources. Suitable content
for your prototype can be found on the web e.g. images. Use creative commons
(http://search.creativecommons.org/) or Wikimedia Commons
(http://commons.wikimedia.org/wiki/Main_Page) as a starting point to find content.
Remember the content you include in your site must be licensed for re-use. Do not spend
excessive amounts of time researching and gathering content. The purpose is to provide a
clear indication of how the final website could look and function. The client would provide
the actual content at a later point if they are happy with the website you have proposed.
Students must not use templates that they have not designed or created in the website
assessment. This includes website building applications, free HTML5 website templates,
or any software that is available to help with the assessment. You must create your own
HTML pages including CSS files and ideally you will do this through using notepad or
similar text editor.
Aim
The aim is to create a website for the Retail Camping Company (RCC).
Task 1– 25 Marks
HTML
The website must be developed using HTML 5 and feature a minimum of SIX (6) interlinked
pages which can also be viewed on a mobile device. The website must feature the content
described above and meet the following criteria:
• Researched relevant content to inform the design of the website.
• Be usable in at least TWO (2) different web browsers including being optimised for
mobile devices and responsive design. You should consult your tutor for guidance on
the specific browsers and versions you should use.
• Include relevant images of camping equipment you have selected from your research
including use of headers, sections and footers.
• Home Page:
o Minimal text with visuals to break up the written content.
o Navigation bar (with links inside the bar and hover over tabs)
o Responsive design and at least one plugin
o Header
o Sections
o Footer (including social media links)
• Reviews page: with responsive contact section including first name, last name, and
submit button (through email)
• Camping Equipment, Furniture Page and Offers and Package page with responsive
resize design and including TWO (2) different plug ins, catalogue style and animated
text search for products.
• Basket – Page created which allows the customers to add products to their basket.
