Monday — Friday 10:30AM - 12:45PM (Summer 2020 CS 4640 will be a web-based course
Zoom link: please refer to Collab
(meet during class hours)
By default, class meetings will be recorded and
made available under Collab's "class recordings."
Although attendance is not required,
to maximize your learning experience, you are expected to attend class meetings.
If attendance or participation is low,
class meetings may not be recorded or made available.
The way web software is built has been rapidly changing.
As use of the world wide web has shifted from information presentation
to information gathering to direct customer sales (e-commerce)
to enterprise applications, the amount and complexity of software
has steadily been increasing.
Many new technologies and frameworks have emerged everyday.
Have you ever wondered what technologies, frameworks,
or architectural styles you should use?
What programming languages you should be familiar with?
After you graduate, what languages will be popular or
will be in great demand?
How will you keep up with web development technologies?
According to the UVA CS Industrial Advisory Board meeting,
companies prioritize the foundation of web development over
any specific technologies or frameworks.
This course will help you see how fundamental concepts
of web development can be applied to develop reliable
and usable web software regardless of the technologies or
languages or frameworks.
Although we put our emphasis on the concepts,
you will develop dynamic web software with several commonly
used programming languages and technologies.
You will work on user interface design, front end development,
back end development, and web-based information retrieval and processing.
Over the semester, you will work on each programming assignment
with a partner.
Each assignment will be a step in creating a web application.
You will be able to choose what to build,
with the assignment constraining the features that must be used.
By the end of the semester, you will have built a dynamic web application, hosting on
Google Cloud Platform
With a large portion of the process that involves team work,
interpersonal skills and conflict management, and time management,
this course will help you practice and prepare for your professional development.
- Demonstrate an understanding of the client-server,
message-passing computing models, data persistence and sharing,
and the quantitative engineering principles for
how to build web-based software
by developing usable, reliable, and effective web applications
- Realize that usability is more important than efficiency
for almost all modern software projects,
and often the primary factor that leads to product success
- Evaluate your project for compliance with client requirements
and the usability evaluation criteria
- Apply usability concepts to real-life scenarios
and suggest potential improvement from an engineer's perspective
- Apply skills and concepts to learn new web development frameworks, technologies, and languages
- Collaborate with your project partner professionally and contribute fairly
- Communicate ideas with others through project demonstration and within a group learning environment
You must have passed CS 2150 (Program and Data Representation)
with a grade of C- or better.
Programming skills are required
and you are expected to know HTML or learn on your own.
You are expected to work on a project — deciding on an architecture of your system
and implementing a web application that interacts with a database to provide services.
While developing a web application within approximately 3 weeks may seem challenging,
it is doable — you must be willing to learn and do it
everyone can be successful in this course.
You do not have to purchase any textbook for this course,
unless you want to (the book information will be provided on the handout).
additional references that can be relevant for further reading
will be provided on the Schedule
You are expected to read the relevant material before class meeting.
The schedule for the readings is given on the
The lectures may not cover everything in the readings and
will often include material not found in the readings (based on class discussion).
To facilitate your learning process,
the course structure consists of four main activities:
in-class exercises, lab-style activities, homework assignments, and a final exam.
1. In-class exercises
Five main purposes of this activity are to help you to
(i) understand the underlying concepts and apply them
to develop a web application,
(ii) introduce specific languages or technologies,
(iii) get ready to work on homework assignments,
(iv) prepare for the final exam, and
(v) practice skills web engineers need
(such as technical skills, software evaluation, collaboration, and communication).
You are encouraged to work in small groups,
allowing peer learning and
imitating industrial software development and quality assurance scenarios.
Each exercise is designed to get you to think
about some specific aspect of the material we are learning that day.
All exercises are hands-on and practical,
and require programming.
There will be five in-class exercises, scheduled on most Wednesdays and Fridays, and some Mondays.
Some will be done in small groups and some may be individual exercises.
They will be graded on a "done / not done" basis.
Credit can only be received if submitted by the deadline.
If you miss class,
you should do the posted exercise on your own to learn the material.
No make-up exercise will be given; no late exercise will be accepted.
2. Lab-style activities
The best way to learn web development is to do it, and do it often.
To help you practice and maximize hands-on experience,
we will do lab-style activities almost every class meeting.
These activities serve the same purposes as in-class exercises.
The difference is that they are not graded.
You will have multiple opportunities to explore
the usability of existing web software and
share your opinion through discussion or writing.
You will also experience a variety of web development concepts.
Lab-style activities will
help you get started with web development languages or technologies,
and explore web-specific features.
You are the main driver of your learning success.
Your engagement and participation is the most important aspect of your learning experience.
You are encouraged to do all the activities although
no submission is requried.
3. Homework assignments
Homework assignments are the main mechanism to help you learn
web software development and apply the concepts to
build a portfolio-worthy web application piece-by-piece.
Some homework assignments will be written
and most will require programming.
All will allow collaboration with one partner to help you practice teamworking skills.
The UVA Honor Code
is in effect.
Please refer to the collaboration
sections of the course
Assignments will be posted on the class website
and discussed in class.
You will submit your homework assignments electronically.
More details on submission guidelines will be provided on the assignment pages.
Most assignments require demonstration to an instructor or course staff
for grading purpose – allowing you to practice your presentation
and to "sell" your project.
Homework assignments help you develop competency in basic and advanced concepts.
Each homework is a step toward your course project
and your professional development.
It is important that you manage your time wisely.
All homework assignments must be submitted
before class on the day they are due.
Any submission received after this time will be considered to be late
Changing an assignment after the due date without prior permission
will be treated as a late submission.
At the end of the Summer session,
we will have a "Showtime."
You will demonstrate how your system works,
and explain your design decisions and features
that improve the usability of your system.
You are encouraged to discuss your classmates' design and implementation.
You may find something interesting from their systems.
This is a great opportunity to share ideas and opinions;
you may learn something useful for your future projects.
The fun part is, we will vote for
"the best usable project"
and "the coolest project."
You are expected to have a backup disk (or storage somewhere)
for every assignment you turn in.
In this way, if there is any problem with the copy
that is handed in the backup can be used for grading purposes.
4. Final Exam
We will have a take-home final exam.
Final exam is comprehensive, open book / notes / web / IDE, no collaboration.
Details will be provided on the final exam guide.
If you know in advance that you are unable to make an exam
for a valid and unavoidable reason (such as a scheduled surgery, etc),
you must notify me at least one week before the scheduled exam date
to make arrangements for a make-up.
Appropriate documentation (as determined by instructor) is required.
If you miss an exam due to a university-accepted excused absence,
you must notify me within 24 hours of your absence
to make arrangements for a make-up,
and submit approved documentation.
Failure to follow either of these policies will result
in a zero grade on the exam.
The grade you will earn for this course will be based on
how well you demonstrate your understanding through the following assessments.
- In-class exercises: 25% (5 in-class exercises, 5% each)
- Homework assignments: 50% (course project)
- ( 4%) Assignment 1: Project proposal
- (12%) Assignment 2: Client-side — frontend
- (16%) Assignment 3: Server-side — backend and data persistence
- (18%) Assignment 4: Final deliverable — frontend and backend
- Exam: 25% (comprehensive)
Your overall score will be mapped to a letter grade as follows:
|You get||If you score|
|A+ ||>= 98|
|A ||>= 93|
|A- ||>= 90|
|B+ ||>= 87|
|B ||>= 83|
|B- ||>= 80|
|C+ ||>= 77|
|C ||>= 73|
|C- ||>= 70|
|D+ ||>= 67|
|D ||>= 63|
|D- ||>= 60|
|F ||< 60|
By default, grades will not be rounded in this course.
Per the University grading policy,
the GC/CR/NC grading option for undergraduates introduced in the Spring 2020 semester will NOT
be available in summer.
We will use
for a discussion board.
This is the place where you can seek help, offer help,
share your thoughts and discoveries,
or discuss technical difficulties and potential troubleshooting.
Information for accessing our class Piazza site will be provided
on the first day of class.
Ask all technical questions about the material or the assignments on Piazza.
You may post any reasonable class-related topics.
- Real-life software problems:
Start a discussion about a problem with a real-life web application
that is related to our class
(good or bad usability, design, construction, etc.)
- Real-life troubleshooting:
Start a discussion about your experience, tutorial, suggestion, and troubleshooting
that is related to our class
- Start a thread about an error in the handouts or slides,
or about a topic that goes beyond what we discuss in class
- Post questions to an appropriate thread and
they will be answered by the instructor or classmate
- Give an answer to a classmate's question
Posting program source code publicly will usually
be considered an honor code violation.
If you need to include a "fragment" of your code in your post,
please make your post "private" and tag instructor.
Updates to the course web page will generally be noted on the Piazza page.
The School of Engineering and Applied Science relies upon
and cherishes its community of trust.
We firmly endorse, uphold, and embrace the University’s Honor principle
that students will not lie, cheat, or steal, nor shall they tolerate those
who do. We recognize that even one honor infraction can destroy
an exemplary reputation that has taken years to build.
Acting in a manner consistent with the principles of honor will benefit
every member of the community both while enrolled in the Engineering School
and in the future.
Students are expected to be familiar with the university honor code,
including the section on
Each assignment will describe allowed collaborations,
and deviations from these will be considered Honor violations.
If you are in doubt regarding the requirements,
please consult with me before you complete any requirement of this course.
Unless otherwise noted,
exams and individual assignments will be considered pledged
that you have neither given nor received help.
(Among other things, this means that you are not allowed to describe
problems on an exam to a student who has not taken it yet.
You are not allowed to show exam papers to another student
or view another student’s exam papers while working on an exam.)
Send, receiving or otherwise copying electronic files
that are part of course assignments are not allowed collaborations
(except for those explicitly allowed in assignment instructions).
Assignments or exams where honor infractions or
prohibited collaborations occur will receive a zero grade
for that entire assignment or exam,
as well as a full letter-grade penalty on the course grade.
Such infractions will also be submitted to the Honor Committee
if that is appropriate.
Students who have had prohibited collaborations
may not be allowed to work with partners on remaining homeworks.

Statement on Violence
The University of Virginia is dedicated to providing a safe and equitable learning environment for all students.
To that end, it is vital that you know two values that I and the University hold as critically important:
- Power-based personal violence will not be tolerated.
- Everyone has a responsibility to do their part to maintain a safe community on Grounds.
If you or someone you know has been affected by power-based personal violence,
more information can be found on the UVA Sexual Violence website that
describes reporting options and resources available -
As your professor and as a person,
know that I care about you and your well-being and stand ready to provide support and resources as I can.
As a faculty member, I am a responsible employee,
which means that I am required by University policy and federal law to report
what you tell me to the University's Title IX Coordinator.
The Title IX Coordinator's job is to ensure that the reporting student receives the resources
and support that they need, while also reviewing the information presented to determine
whether further action is necessary to ensure survivor safety and the safety of the University community.
If you would rather keep this information confidential,
there are Confidential Employees you can talk to on Grounds
The worst possible situation would be for you or your friend to remain silent
when there are so many here willing and able to help.
