Continuous Assessment 2
Date set: 16th November, 2019
Hand-in date: 11:59am Friday 15th November, 2019
This continuous assessment (CA) comprises 25% of the overall module assessment.
Note that both paper (BART) and electronic submissions are required and instructions are provided
at the end of the specification. The specification will be discussed in the lecture on Friday 18th
October 2019. Students have until 25th October to raise any questions regarding the specification
either in lectures or by email. Up to this date the module leader may make adaptations to clarify
the assessment. After this date the specification will not change.
This CA is designed to test the programming concepts that we will cover in the first eight weeks
of term, particularly variables, built-in types, lists, loops, operators, conditionals, modules, data
structures, the event driven design pattern and exceptions.
Specification
Smart systems are automated systems that adapt to input data streams. Alarm clocks are an
everyday item that we use to schedule our lives. The scope for a smart alarm clock that knows
about our schedule for the day, knows what the weather will be and can tell the time has the
potential to be very useful. In this assignment you will implement a smart alarm clock.
The implementation of an alarm clock is not like a typical python script you may have developed
before. An alarm clock will need to run continuously and respond to events rather than responding
inline with user inputs. These events can be scheduled by the user or triggered by extenal events
and require an event driven software architecture that uses scheduled tasks. Your smart alarm will
have a series of features defined below and use the modules specified to achieve this smart event
driven behaviour.
• Alarms
The program should enable the user to schedule and cancel alarms. The alarm should notify
the user when the relevant time is reached. Alarm functionality should be defined using the
sched and time modules.
[10 marks]
• Notifications
A key part of an alarm is notifying the user to an event. The smart alarm will use two
types of notifications. For alarm notification announcements we will use text-to-speech voice

announcements using the pyttsx3 module. For less immidiate notifications, silent notifications
will be tracked through a personal notification queue.
[10 marks]
• Smart-ness
To make your alarm clock adaptable it will need some smarts. The intelligence in your system
will be achieved by pulling information from the internet and merging it with local information
in the scheduled alarms. Pull in the weather and news data using the requests module and the
Openweathermap API (https://openweathermap.org) and News API(https://newsapi.
org/).
[10 marks]
• User interface
All smart systems are designed with automation in mind so the interface should should be
minimal, however, the user needs to be able to set and cancel alarms. Implement a basic web
interface using the flask module that runs on localhost. The interface should enable the user
to set alarms and see basic information, such as notifications about ‘passive’ events.
[10 marks]
• Bonus features – max 10 marks
There are four possible bonus features for this assignment worth 5 marks each. However, the
maximum mark for this section is 10 marks so not all bonus features are necessary to score
full marks.
– Configuration file: Sensitive information, such as api keys and other user credentials,
and filepaths for application resources should be stored in a configuration file rather than
in the source code. Passwords should also not be needed and should never be included
in source code. Create a json file called config.json that contains the API keys and
credentials for any web services and filepath information for any local resources, such as
a log file.
[5 marks]
– Logging: A central functionality in any event driven architecture is tracking and handling events. This means the system should be executing tasks remotely, while you
aren’t watching. Logging is therefore an important feature that will make the program
accountable and make it possible to trace behaviour and recover state. You should log
all events that happen in your smart alarm and categorise different types of event that
may be treated in different ways.
[5 marks]
– Testing: As your software will depend on third party services and is designed to run
continuously there is a good chance errors will occur while the program is deployed. As
part of your code you should include unit testing for each of your functions and include
a deployment test cycle as well as scheduling tests to regularly check the functionality
of your program.
[5 marks]
– Private web service notifications: Many users use a range of private internet services, such as office365, youtube and netflix. Most of these services provide an API

provision so that applications can receive notifications to integrate with their services.
Add third party services to your notification system by generating API keys and pulling
information from these services.
[5 marks]
You should carefully follow the functionality described and use the modules recommended in each
section. If you design a program with a different structure or depend on alternative modules you
will not attract as many marks.

Submitting your work
The CA requires both paper and electronic submissions.
Paper You should submit a paper copy of your formatted source code and a single screenshot
of your user interface to the Harrison Student Services Office in the foyer of the Harrison
Building by the deadline of 11:59am Friday 15th November, 2019.
The paper copy of the source code can be generated by exporting from PyCharm or printing from notepad++. These options will retain the formatting, line numbers and syntax
highlighting.
Paper submissions should have the BART cover sheet securely attached to the front and
should be anonymous (contain your student rather than your name).
Electronic You should submit your source code and any supporting files via the electronic submission system at http://empslocal.ex.ac.uk/submit/. Use the category containing ECM1400
and CA2. Upload a compressed version of your files as a single file, use the zip compression
format.
After you click proceed you will be sent an email by the submit system asking you to confirm
your submission by following a link. Your submission is not confirmed until you do this. It
is best to do it straightaway, but there is a few hours leeway after the deadline has passed.
It is also possible to unsubmit and resubmit electronic coursework — follow the instructions
on the submission website.
Both paper and online submissions must be completed by the deadline else your submissions
will be considered late and your mark will be capped at 40%.
