Syllabus, Social Media and Society, 2018
Sharing is caring. I found other people’s syllabi very helpful when designing my two new courses - Social Media and Society and Digital Culture. Both are masters’ level, both will be taught at Tallinn University in the New Media Masters program this fall. I am still working on the details of Digital Culture, but here’s Social Media and Society:
Social Media and Society, 4ETC
taught by: Katrin Tiidenberg, PhD
Short description: ‘Social Media and Society’ considers the role of networked communication technologies, social media, and specific platforms and applications in personal and societal life. It takes a sociological perspective on society (conceptualized via structure, agency, social institutions, inequality, social change and knowledges) and makes sense of social media via the concepts of affordances, platforms, connectivity, (in)visibility and user practices. Relying on relevant academic work that conceptualizes the social dynamics and implications of social media, we will explore the personal, social, economical, political and ideological aspects of living in networked, digitally saturated societies.
Course structure:
Lectures
In-class discussions
3 in-class exit quizzes (about the content of the class)
6 in-class reading quizzes (about the reading assigned for that class).
Participation in and passing the class involves reading a total of 13 texts (journal article or book chapter length) in academic English.
Grading:
Grades are based on the total number of accumulated points (100p = 100%). Points are earned from in-class quizzes (reading or class content related) and from the written exam. Maximum possible points: 45 - quizzes (5 per quiz), 55 – final exam.

What is Python?
Python is a popular programming language. It was created by Guido van Rossum, and released in 1991.
It is used for:
web development (server-side),
software development,
mathematics,
system scripting.
What can Python do?
Python can be used on a server to create web applications.
Python can be used alongside software to create workflows.
Python can connect to database systems. It can also read and modify files.
Python can be used to handle big data and perform complex mathematics.
Python can be used for rapid prototyping, or for production-ready software development.
Why Python?
Python works on different platforms (Windows, Mac, Linux, Raspberry Pi, etc).
Python has a simple syntax similar to the English language.
Python has syntax that allows developers to write programs with fewer lines than some other programming languages.
Python runs on an interpreter system, meaning that code can be executed as soon as it is written. This means that prototyping can be very quick.
Python can be treated in a procedural way, an object-oriented way or a functional way.
Good to know
The most recent major version of Python is Python 3, which we shall be using in this tutorial. However, Python 2, although not being updated with anything other than security updates, is still quite popular.
In this tutorial Python will be written in a text editor. It is possible to write Python in an Integrated Development Environment, such as Thonny, Pycharm, Netbeans or Eclipse which are particularly useful when managing larger collections of Python files.
Python Syntax compared to other programming languages
Python was designed for readability, and has some similarities to the English language with influence from mathematics.
Python uses new lines to complete a command, as opposed to other programming languages which often use semicolons or parentheses.
Python relies on indentation, using whitespace, to define scope; such as the scope of loops, functions and classes. Other programming languages often use curly-brackets for this purpose.
Example print("Hello, World!"

25 Top Android Mobile App Ideas to Follow in 2020
Can we imagine starting our day without a mobile application? We need an app for setting the alarm, one which reminds us of our meetings, another for playing songs, and even one mobile application for reading out news to us. So the moral is, mobile apps have taken a special place in our lives, and we cannot deny our reliability on them.
After seeing this essential reliability, android mobile app trends needed to upgrade in the year 2020. Mobile app development companies have come up with some more useful ideas and trends for android app development. Let’s discuss each in brief.
1- Augmented Reality is winning hearts:
Want to design your room? Or do you want to try a dress you saw on an online shopping app without buying it? Well then AR- Augmented Reality; is there to help you. Already a few websites like Pepperfry have started giving AR options where you can see which furniture will fit in your room. Mobile apps laced with AR features will be the top app trend to follow in 2020.
2- One Scan to make your PDF:
Keeping and carrying hard copies of your documents is so troublesome. But then what is the alternative? A mobile app that scans and converts all your documents into a single PDF file can help. This type of mobile apps will trend because of the mass digitization going on. People find carrying soft copies more convenient and safe than carrying hard copies of documents. Also, adding a cloud feature to this app will help in accessing the PDF on any platform.
3- Fitness apps are trendy:
People love fitness apps because it provides a one-stop solution to its users. It helps them organize their diet, track their footsteps, set health goals, and much more. Adding videos of yoga, exercise, and providing health consultants can enhance the beauty of such android mobile apps.
4- Say no to queues with Check-out apps:
No one likes to wait in a long queue at a retail store, and so Amazon came up with the self-check-out retail stores, Amazon Go. These types of apps will be increasingly used in the coming years. Amazon Go app allows users to scan the products on our mobile while shopping and make the payment online after checking out from the store. We just need to tap our phones just like we do on metro stations with metro cards.
5- Real-time translator apps:
It is almost impossible to mug up all the languages in the world. In such scenarios, real-time translator apps can save us. This app will listen to the other language and convert it into our language in real-time and also the vice-versa. Adding a memory feature can help the user in learning that language in the future if needed.
6- Let’s chat with bots:
Chat Bots are useful in playing the role of humans. They can interact like humans based on customer’s queries. These apps are based on Artificial intelligence technology, which is why they behave like humans. AI Chat Bots are helpful for any mobile app as they can support live chat without the need for human interference. Unlike humans, they never get exhausted and have the capability of interacting with any number of queries according to the user’s requirement.
7- Take me for a Bike Ride!
Due to increasing traffic and massive rates, cabs are losing their fans. The people who travel alone prefer to book bike rides rather than a car. The reason is pretty simple, it’s cheaper, can take shortcuts, and doesn’t get stuck in traffic jams, so it’s faster too. So hiring developers for getting a bike ride mobile app made is a great option. It will be a trend in 2020.
8- Safe Calling apps:
With the increase in spam calls, harassment, and forgery, Safe Calling mobile apps need to be used. Such apps will recognize the number if it is a spam or not based on the customer review database. Also, it will enable you to record the call and upload it to cyber crime cells helplines if needed. This will help you stay safe and also work as a preventive method in crimes over phone calls.
9- Scan and buy:
Imagine you visit your friend’s house, and you see a gorgeous center table in her living area. You also desire to buy that table, but you feel awkward in asking about it in detail from your friend. Now, what will you do? If you have a Scan and buy mobile app, you can scan that table, and it will show you all the results from where you can buy the same or a close substitute for that table. Such android mobile apps are useful as well as fun to use.
10- Criminal alert app:
Seeing a missing person or a wanted criminal on roads without knowing them can be a safety concern for all of us. The criminal alert app idea is such that the app will alert you of criminals in your area. This will save a life as well as help in catching the criminal whose pictures are there on the app.
11- Baby care and maternity app:
In the world where digital reliability is growing day by day, having an android mobile app for baby and mother care can help many lives. Such apps can be used by mom to be or even by men who are soon going to be a dad. These mobile apps will provide diet solutions for both baby and mother, exercise videos during pregnancy, nearby hospital routes, appointments of gynecologists or pediatricians, baby care products, and much more.
12- Stay away from crime:
Imagine having a mobile app that can tell you which area in your city is not safe and why. This is not fiction anymore. Such apps are a reality today and will trend in 2020. The heat map feature can also be added to this type of mobile apps to show the user the safe and unsafe areas of the city at a glance. Allowing users to report a crime on this app anonymously or with identity( as per the user’s choice) will enhance the quality and reliability of the app. And also help the surveillance cells to improve their services.
13- Food suggestion/blogging apps:
We all know how Zomato was started. Before starting with food delivery, it was a food blogging website and was known as Foodiebay.com, where people used to get hundreds of restaurant menus, reviews of eating joints, and recommendations. Such mobile apps will be a significant trend in 2020 as food blogging has come up as a career option for youth. Providing these bloggers with a separate mobile app will help them get better recognition too.
14- Find me a parking space:
We all will agree to the fact that finding a parking space whenever we go out is so annoying. What if an app will help us find a parking space in that area? It’ll solve a huge problem for us. Designers can design such mobile apps, which will help us find a registered parking space near us. Adding an e-parking ticket feature will take the mobile app to the next level.
15- Choose your table app:
We need privacy in a corner seat for a cozy date or need the central table for making a grand announcement, in restaurants, it’s sometimes challenging to get the desired seating arrangement for what we’ve planned. With a mobile app which has graphical views, we can choose the desired seats or table and book them for a specific time( just like bus ticket reservation).
16- Virtual group study app:
It’s not always safe to go to a friend’s place for group study. You can also consider if one of the friends might be sick/out of town, but you have to do your assignments? In group study apps, students can meet up on this forum and prepare for their exams/projects along with other students who are studying on the same subject. The app must provide them with study material, tools, video lectures, discussion helps, guides, etc. Users can also create a virtual room where only he and his friends can enter and video call while watching online lectures together virtually. Hire android developer if you are mesmerized by this idea and want to get it made for you.
17- An app for Language Lovers:
Many people wish to learn a new language but don’t find the perfect solution. To help such people, you can design android apps, which will enable the user to learn new languages thoroughly. Adding levels like basic, intermediate, and professional will increase user engagement on your mobile app.
18- Pet Care and adoption apps:
Since there are many pet lovers out there, they will be disappointed if the digitization of the world doesn’t consider their needs. Pet care companies or veterinarians can hire android developers to get an app made for pet care. People willing to adopt pets can also register on this app. Adding a section for the license(new or renewal) will be a cherry on the cake for dog owners since, from May 2019, it is a compulsion in India to have a license if you own a dog.
19- Gift Suggestion apps:
Whenever it comes to selecting a gift for our loved ones, we end up getting confused. This mobile app can look over the entire history of our friend’s social feed to suggest the best gift idea for our friend based upon the content they posted. Such mobile apps are developed, keeping in mind the concept of data analysis. Problem solver!
20-Food Wastage Prevention Apps:
We all have seen that once the parties are over, a lot of food is left untouched or unused. People even throw food in the dustbin, which leads to the wastage of food. This issue could be resolved. We can develop a mobile app that can inform the registered orphanage/nursing homes about the leftover untouched food so that they can come to get it as per their need.
21- Car rental apps:
How many names come to your mind when you think about car rental mobile apps? Just Zoomcar, isn’t it?

Do you want to become a Python Developer without having to spend a lot of money on books and boring theoretical courses?
Do you often hear things like “You should learn Python!” or “Just write a Python script for that!”or even “Python is so easy to learn!”? Python here, Python there, Python everywhere?
“As a Python beginner, I find this course is concise, easy to understand and structured. Also, Mihai responses to my question during the course promptly. I highly recommend this training course.” by Johnny Wang
✔ What’s this course all about?
Python 3 programming course aimed at anyone having little or no experience in coding and a great desire to start learning Python from scratch. This hands-on training takes you from “Hello World!” to advanced Python topics in just a few hours.
First, you will learn and practice every Python 3 key concept, which is explained in one or more video lectures, usually followed by a short quiz and several exercises.
Each video is filled with relevant examples, created in a learn-by-doing fashion and the quizzes, coding exercises and assignments will help you consolidate the main ideas behind each Python 3 topic.
After laying the foundation, you will start exploring some advanced Python 3 topics, thus quickly growing your skills from Zero to Beginner to Intermediate to Advanced to Superhero level.
Next, we will build a scientific calculator in Python 3, having a basic user menu and both simple and advanced math operations available: addition, subtraction, multiplication, division, modulo, raising to a power, square root, logarithm, as well as trigonometric functions like sin, cos and tan.
Finally, you will gain some real-life skills that you can use at most programming and IT-related jobs: Excel Automation, Database Automation, Data Analysis Automation, Test Automation, Web Scraping and Network Automation, among others, using Python 3.
You will also be able to download printable cheat sheets to have every Python 3 concept at hand whenever you need it, as well as a 200+ pages Python 3 e-book that can help you continue studying whenever you don’t feel like watching videos or solving coding exercises. What more can you ask for?
As a final bonus, you will also get all the Python 2 content in my older course, so you will be able to interact with systems still running the legacy “edition” of Python, which have not yet migrated to the latest version. It never hurts to be fluent in both versions of this amazingly popular programming language, although Python 3 is the most relevant version today.
This course is the first one in a trilogy especially designed for learning Python 3 from scratch and then using your skills and knowledge to solve 250 multiple-choice quizzes (course 2, live: ‘Python 3 Workout – Solve 250 Multiple-Choice Quizzes!’) and 250 coding exercises (course 3, in progress: ‘Python 3 Workout – Solve 250 Coding Exercises!’), respectively. So, check out these courses as well, for a complete and comprehensive learning experience.
“I am really enjoying this course thus far. 10-12 minutes into the course and I’ve already written my first line of Python code, which I think it’s pretty cool, since I’ve never programmed before. I’m planning to finish this course and apply for a junior programmer, part-time job. Thanks for this training!” by Andrei Vasilescu

COMPUTER ASSIGNMENT HELP
Question 1. The Relational model (10 marks).
A spreadsheet was used to keep data for the booking system of the ABC Clinic, with sample data shown in Table 1. Columns 1-4 contain information for doctors, Columns 5-9 contain information for patients and the last 3 columns contain information for patient’s appointments with doctors. The spreadsheet for the table is also available on Canvas.
Table 1. Data for the ABC Clinic
With more and more patients and doctors, the ABC Clinic decides to go for database system to manage data. You are asked to design a relational database to keep data to answer clinic operation queries such as:
List the patient appointments for each doctor for a given date.
When a patient rings to make an appointment, give the available time slots for a given date.
Retrieve the address of patients to send notices via mail services.
Answer questions:
1.1. (4 marks) A database schema of one relation as shown below is proposed, where semantics of attributes are self-explanatory. Discuss at least two weaknesses of this design.
ABC(doc-name, doc-gender, registration_num, qualification, pat-name, pat-gender,
DOB, address, phone-num, appoint-date, appoint-time, type)
1.2. (6 marks) Propose your own design for the database. Your design must be able to keep all information shown in Table 1. Explain your design. Give the schema for each relation in your database and specify their data integrity constraints (underline primary keys and put asterisk for foreign keys).
Question 2. Relational model — SQL DDL and DML (10 marks)
According to your design for the ABC database in Question 1.2, complete below tasks to populate your database with the data shown in Table 1.
2.1. (5 marks) Give the CREATE TABLE statement for each relation, including primary key and any foreign key constraints.
2.2. (5 marks) Give the INSERT INTO statements for each relation in your design. All data shown in Table 1 must be inserted into your database.
Question 3. SQL (30 marks).
In addition to the lecture notes, you should also study by yourself the SQL*Plus tutorial on Canvas (the Oracle section) and other resources for Oracle syntax and useful functions.
The ER model for the Academics database is as follows:
The relational schema for the Academics database is as follows:
DEPARTMENT(deptnum, descrip, instname, deptname, state, postcode)
ACADEMIC(acnum, deptnum*, famname, givename, initials, title)
PAPER(panum, title)
AUTHOR(panum*, acnum*)
FIELD(fieldnum, id, title)
INTEREST(fieldnum*, acnum*, descrip)
Some notes on the Academics database:
An academic department belongs to one institution (instname) and often has many academics. An academic only works for one department.
Research papers (PAPER) are often authored by several academics, and of course an academic often writes several papers (AUTHOR).
A research field (FIELD) often attracts many academics and an academic can have interest (INTEREST) in several research fields.
Download and run the SQL script academics.sql on Canvas (the Oracle section) to define and populate the Academics database in your Oracle account.
Write ONE SQL query for each of questions 3.1–3.8, and each component of an SQL statement must be on a separate line. Your query should not produce duplicates in output but use DISTINCT only if necessary. Include answers for Questions 3.9 and 3.10 as comments starting with “//” to make an SQL script executable in SQL Developer.
Each question below is worth 3 marks.

Question 4. ER model (30 marks).
TXT is a logistics and transport company. You are asked to design a database for scheduling their transport jobs. Requirements for the database are as follows:
Each truck has a unique registration No, and is also described by type, and year made.
Each customer of TXT has a unique ABN and is also described by the name, and contact phone number.
Delivery jobs are identified by the unique job No, and are also described by “from” and “to” destinations, and estimated distance to travel.
Drivers are identified by the unique employee ID, and are also described by first name, last name, address and phone number.
A customer may book in several delivery jobs and a job is from only one customer. A job must have an “owning” customer.
A driver can be assigned several delivery jobs but a job has only one driver. Some description about the job is also recorded. Each job has a Status (eg open, complete,etc) and this is maintained in the database.
A job is assigned only one truck but a truck can be assigned to several jobs.
According to the given description, state any assumptions you make and construct an Entity Relationship (ER) diagram for the database. You must represent entities, relationships and their attributes, and all applicable constraints in your ER diagram. Explain any concepts in the description that cannot be expressed in the ER diagram.
Your ER diagram must only use notations from the lecture notes and must not be hand drawn. ER diagrams using other notations will receive zero mark for this question.
You can use the ER diagramming tool Dia, which can be downloaded from Canvas (The Tools section) and is also available as an App on mydesktop.rmit.edu.au. When exporting your ER diagram in Dia to a pdf file, you need to first set “page setup” to “Fit to 1 by 1” so that your pdf diagram scales properly. You can also use any other diagramming tool.
Some common errors in ER diagrams:
If the scenario is set in say, a club, you do not need an entity for the club. The arrangement you depict in the ER diagram isthe club.
Entities do not connect to other entities with straight lines. Entities have relationships to/with other entities so there has to be a relationship between connected entities.
Every entity must have a primary key.
The names of all relationships and entities must be unique.
There are no foreign keys in ER diagrams. They come about as part of mapping an ER model into a relational schema.
Question 5. Relational database design. (20 marks).
Designing an ER diagram is the first step for database design. It is critical that we understand what makes a good design. Figure 2 is an ER diagram designed for the Orders database about customers and their orders for a company. The semantics of attributes, entity sets and relationships is as expressed in their names. Each item in the database must have an “owning” salesman, whether or not it is being ordered.
5.1. (5 marks) Discuss any issues with the given ER diagram. Give your suggested ER diagram.
5.2. (15 marks) Map your suggested ER diagram to a relational database schema. For each relation schema in the mapped relational database schema, indicate the primary key (underline) and any foreign keys (asterisk).

A research field (FIELD) often attracts many academics and an academic can have interest (INTEREST) in several research fields.
Download and run the SQL script academics.sql on Canvas (the Oracle section) to define and populate the Academics database in your Oracle account.
Write ONE SQL query for each of questions 3.1–3.8, and each component of an SQL statement must be on a separate line. Your query should not produce duplicates in output but use DISTINCT only if necessary. Include answers for Questions 3.9 and 3.10 as comments starting with “//” to make an SQL script executable in SQL Developer.
Each question below is worth 3 marks.
3.1. List the names of all the institutions (instname) currently in the database.
3.2. How many academics are there in the department where deptnum=100. Return the total number.
3.3. List in alphabetical order the family name (famname) and given name (givename) of academics who has a title.
3.4. List papers whose title contains the words “Data” or “Software”, in upper or lower cases. List the panumand titleof these papers.
3.5. Return the panumof papers written by the academic “Mark Yee”.
3.6. Return the famnameand givenameof academics whose acnumis in the range [100..199] or whose givenamestarts with “S”.
3.7. List the panumof papers having at least two authors.
3.8. List in alphabetical order the famname, givenameof academics who work for institutions in Queensland. Note: the value of Queensland in the database is QLD or Qld.
3.9. The below query is intended to list the fieldnum and title of fields whose fieldnum is between 500 and 599 or whose title contains the word ‘Data’. But it has errors. Give the correct SQL query. select fieldnum, title from field where fieldnum >=500 and <=599 or upper(title) like ‘Data%’;
3.10. Describe in English what the output will be from the SQL query below. Do not give a literal description of each line of the query. select acnum, field.fieldnum, title, descrip from field, interest where field.fieldnum=interest.fieldnum and trim(ID) like ‘B.1._’
Question 4. ER model (30 marks).
TXT is a logistics and transport company. You are asked to design a database for scheduling their transport jobs. Requirements for the database are as follows:
Each truck has a unique registration No, and is also described by type, and year made.
Each customer of TXT has a unique ABN and is also described by the name, and contact phone number.
Delivery jobs are identified by the unique job No, and are also described by “from” and “to” destinations, and estimated distance to travel.
Drivers are identified by the unique employee ID, and are also described by first name, last name, address and phone number.
A customer may book in several delivery jobs and a job is from only one customer. A job must have an “owning” customer.
A driver can be assigned several delivery jobs but a job has only one driver. Some description about the job is also recorded. Each job has a Status (eg open, complete,etc) and this is maintained in the database.
A job is assigned only one truck but a truck can be assigned to several jobs.
According to the given description, state any assumptions you make and construct an Entity Relationship (ER) diagram for the database. You must represent entities, relationships and their attributes, and all applicable constraints in your ER diagram. Explain any concepts in the description that cannot be expressed in the ER diagram.
Your ER diagram must only use notations from the lecture notes and must not be hand drawn. ER diagrams using other notations will receive zero mark for this question.
You can use the ER diagramming tool Dia, which can be downloaded from Canvas (The Tools section) and is also available as an App on mydesktop.rmit.edu.au. When exporting your ER diagram in Dia to a pdf file, you need to first set “page setup” to “Fit to 1 by 1” so that your pdf diagram scales properly. You can also use any other diagramming tool.
Some common errors in ER diagrams:
If the scenario is set in say, a club, you do not need an entity for the club. The arrangement you depict in the ER diagram isthe club.
Entities do not connect to other entities with straight lines. Entities have relationships to/with other entities so there has to be a relationship between connected entities.
Every entity must have a primary key.
The names of all relationships and entities must be unique.
There are no foreign keys in ER diagrams. They come about as part of mapping an ER model into a relational schema.
Question 5. Relational database design. (20 marks).
Designing an ER diagram is the first step for database design. It is critical that we understand what makes a good design. Figure 2 is an ER diagram designed for the Orders database about customers and their orders for a company. The semantics of attributes, entity sets and relationships is as expressed in their names. Each item in the database must have an “owning” salesman, whether or not it is being ordered.
5.1. (5 marks) Discuss any issues with the given ER diagram. Give your suggested ER diagram.
5.2. (15 marks) Map your suggested ER diagram to a relational database schema. For each relation schema in the mapped relational database schema, indicate the primary key (underline) and any foreign keys (asterisk).

Question 1. The Relational model (10 marks).
A spreadsheet was used to keep data for the booking system of the ABC Clinic, with sample data shown in Table 1. Columns 1-4 contain information for doctors, Columns 5-9 contain information for patients and the last 3 columns contain information for patient’s appointments with doctors. The spreadsheet for the table is also available on Canvas.
Table 1. Data for the ABC Clinic
With more and more patients and doctors, the ABC Clinic decides to go for database system to manage data. You are asked to design a relational database to keep data to answer clinic operation queries such as:
List the patient appointments for each doctor for a given date.
When a patient rings to make an appointment, give the available time slots for a given date.
Retrieve the address of patients to send notices via mail services.
Answer questions:
1.1. (4 marks) A database schema of one relation as shown below is proposed, where semantics of attributes are self-explanatory. Discuss at least two weaknesses of this design.
ABC(doc-name, doc-gender, registration_num, qualification, pat-name, pat-gender,
DOB, address, phone-num, appoint-date, appoint-time, type)
1.2. (6 marks) Propose your own design for the database. Your design must be able to keep all information shown in Table 1. Explain your design. Give the schema for each relation in your database and specify their data integrity constraints (underline primary keys and put asterisk for foreign keys).
Question 2. Relational model — SQL DDL and DML (10 marks)
According to your design for the ABC database in Question 1.2, complete below tasks to populate your database with the data shown in Table 1.
2.1. (5 marks) Give the CREATE TABLE statement for each relation, including primary key and any foreign key constraints.
2.2. (5 marks) Give the INSERT INTO statements for each relation in your design. All data shown in Table 1 must be inserted into your database.
Question 3. SQL (30 marks).
In addition to the lecture notes, you should also study by yourself the SQL*Plus tutorial on Canvas (the Oracle section) and other resources for Oracle syntax and useful functions.
The ER model for the Academics database is as follows:
The relational schema for the Academics database is as follows:
DEPARTMENT(deptnum, descrip, instname, deptname, state, postcode)
ACADEMIC(acnum, deptnum*, famname, givename, initials, title)
PAPER(panum, title)
AUTHOR(panum*, acnum*)
FIELD(fieldnum, id, title)
INTEREST(fieldnum*, acnum*, descrip)
Some notes on the Academics database:
An academic department belongs to one institution (instname) and often has many academics. An academic only works for one department.
