Sketch! This assignment is to write a Python program that makes use of the OpenGL graphics library to make an interactive sketching program that will allow the user to do line drawings. The user should be able to choose from a palette of colors displayed on the screen. When the user clicks the mouse in the color palette area, the drawing tool will switch to using the color selected, much like dipping a paint brush into a new color of paint.

Here are two starter codes. I'm trying to combine them basically but end up with a mess. It's supposed to be mimicking Microsoft Paint. Pick a color and then draw a line with it. There are 3 boxes on the left side, red, green, and blue. When the user clicks the box the line color matches the color of the box. Then the user can click in the space and free draw a line of that color, similar to Microsoft paint.

Urgent need: please solve this question below:

A description of how your chosen Information Systems Technology is currently being used in different areas of business, government or and/or society. If your technology is being used in many different areas, try and focus on four areas that either have a high impact or that interest your group. Be sure to include the impacts that the technology is having on each of these areas. Your impacts should include both quantitative (e.g., financial, etc.) as well as qualitative (e.g., quality of life, etc.) ones. In addition, describe 3-4 advantages and 3-4 disadvantages of the use of the technology in these areas. For the advantages, you should clearly describe how/why these are advantages, whether or not they are sustainable and why. For the disadvantages, you should clearly describe why they are disadvantages, how serious these disadvantages are and whether or not there are any ways to overcome these disadvantages.

Define an interface called Vehicle, which requires the following methods getName: returns a String getTopSpeed: returns an int getMaxPassengers: returns an int Note that the class Car implements this interface and is preloaded (in one of the following questions you will define this class)

For example:

Test

Vehicle v = new Car("BMW", 280, 5); System.out.println(v.getName()); System.out.println(v.getTopSpeed()); System.out.println(v.getMaxPassengers());

Results :

BMW

280

5

Test 2 :

Vehicle v = new Car("Smart", 150, 2); System.out.println(v.getName()); System.out.println(v.getTopSpeed()); System.out.println(v.getMaxPassengers());

Results :

Smart

150

A random variable (RV), x is distributed with a pdf as follows:

f_X(x) = [C × x × (1 – x)]       0 ≤ x ≤ a            (C and a are constants)

         = 0                                otherwise

Hence, determine the following: (i) C; (ii) cumulative probability of x in the range, [(u × a) ≤ x ≤ (v × a)]; where u and v are fractions; (iii) E[x]; (iv) second moment of x ; and, (v) standard deviation of x. Assume: a = 1, u = 0.5 and v = 0.75

Hence, choose the correct set of answers in the multiple-choices listed:

1. Data Flow Diagram

The TOPCAR taxi company is developing a new computer system to be used to support taxi booking and corporate client credit accounts. This computer system aims to automate some manual processes and cut down on labour costs as TOPCAR has many customers from large corporate companies, e.g. CEO, and managers often need taxi trips to the airport. The following describes the activities that must be processed by the computer system:

A client company must first register and open a credit account with TOPCAR at TOPCAR’s website, in which case certain credit checks are made such as checking credit history of client company’s debt level. If the client company has no bad debt history, a credit account for the client company is set up.

At least 24 hours after successful account registration, authorized persons from such client company can request a taxi booking form TOPCAR’s website. When this happens, the availability of a taxi at the requested date and time is checked, as is the credit status of the client company checked. (Note that credit status in finance means a measure of a lender’s willingness to lend money to a particular person or organization, depending on their ability to repay).

If these two checks are successful, a booking is made, and a written confirmation is sent via SMS and emailed to client company. After the customer from the client company has used the taxi, the driver sends in a record of the work, including the cost, and this is added to client company’s account. (Note that driver is an outsourced worker from TOPCAR’s point of view.) At the end of each month, taxi bills are sent via SMS and emailed to client companies for settlement.

From the above description, draw a data flow diagram showing the flow of input information (and/or data) and output information (and/or data) to and from processes and database stores within this computer system and any external environmental elements that interact with this computer system. In this diagram, you must identify the following:

1. processes inside this computer system,                      
2. database stores, external environmental elements that interact with any of the processes identified

in (a)                                                 (5.5 marks)

3. input and output information (or data) to and from each of the processes, database stores, and external environmental elements identified in (a) and (b)        (7.5 marks)

(Hint: there are two environmental elements that interact with this computer system, and six main processes in this computer system)

Suppose as a language designer, you plan to implement a feature called “output-only” parameters. The expected semantics is that all output-only parameters are uninitialized when the callee starts execution; they can be used (both read and write) as other kinds of parameters within the callee; finally, the corresponding actual parameter in the caller is updated to the final values of the “output-only” parameters. Briefly describe one possible implementation of such “output-only” parameters

Create an array of ten strings. Write a program to join and split these strings. Feel free to use any whitespace character.
