CPSC 210 Queue System

codebeat badge

Screenshot of the application

This application lets students taking CPSC 210 at UBC sign up for office hours via a convenient web interface. The app is written in Go, and the web interface uses Bootstrap with some ugly JavaScript magic.

I am a CPSC 210 student, what is this?

If you are a student you are in the wrong place: this website hosts the source code for the queue application. Go to https://cpsc210queue.ugrad.cs.ubc.ca to join the queue as a student.

How to install and run the app

Download and compile

Make sure you have Go installed. On a fresh Linux install, run:

$ go get -u github.com/agottardo/210-queue-system
$ cd$GOPATH/src/github.com/agottardo/210-queue-system
$ go build -o $GOPATH/bin/210-queue-system

You might need to fetch some dependencies using go get -u, followed by their respective Git URL. After following the instructions, you'll have created a binary inside $GOPATH/bin.

Settings and authentication details

In $GOPATH/bin, you'll have to create two JSON files:

authdb.json

This file contains the username and password for each TA:

{
"ta1": "ta1password",
"ta2": "ta2password"
}

config.json

{
"MaxNumTimesHelped": 5,
"AuthSecret": "FlfXgyRSwC2vPbLkaUP5"
}

MaxNumTimesHelped indicates how many times a student can get help over 24 hours, before they get rejected (see more info at the bottom).

AuthSecret is a random string used to hash passwords. Keep it random.

Running

You're done! Run the binary at $GOPATH/bin/210-queue-system to start serving incoming HTTP requests. It might be a good idea to host the application behind a HTTPS proxy, in order to comply with the UBC data protection regulations.

What staff can do

TAs can use their credentials defined in authdb.json to perform the following operations:

TA control panel

TAs can access the panel while offering office hours, and mark students as 'served'. It is important that TAs mark students as served right away, so that wait time estimates are accurate.

JSON data dump

Instructors and TAs can download a dump of all the data contained in the database in JSON format. This can be useful for data analysis purposes during/after the term.

To do so, just go to /jsondump after logging in from the web interface.

Maximum times helped

You can set a limit to the number of times a student can receive help over the range of 24 hours. Once this limit is reached, the student will read a message politely asking them to seek help elsewhere. You can set MaxNumTimesHelped to an insanely high number to disable this feature.

To do so, just go to /jsondump after logging in from the web interface.
Maximum times helped
You can set a limit to the number of times a student can receive help over the range of 24 hours. Once this limit is reached, the student will read a message politely asking them to seek help elsewhere. You can set MaxNumTimesHelped to an insanely high number to disable this feature.

CPSC 210 Queue System
codebeat badge
Screenshot of the application
This application lets students taking CPSC 210 at UBC sign up for office hours via a convenient web interface. The app is
written in Go, and the web interface uses Bootstrap with some ugly JavaScript magic.
I am a CPSC 210 student, what is this?
If you are a student you are in the wrong place: this website hosts the source code for the queue application. Go to https://cpsc210queue.ugrad.cs.ubc.ca to join the queue as a student.
How to install and run the app
Download and compile
Make sure you have Go installed. On a fresh Linux install, run:
$ go get -u github.com/agottardo/210-queue-system
$ cd$GOPATH/src/github.com/agottardo/210-queue-system
$ go build -o $GOPATH/bin/210-queue-system
You might need to fetch some dependencies using go get -u, followed by their respective Git URL. After following the instructions, you'll have created a binary inside $GOPATH/bin.
Settings and authentication details
In $GOPATH/bin, you'll have to create two JSON files:
authdb.json
This file contains the username and password for each TA:
{
"ta1": "ta1password",
"ta2": "ta2password"
}
config.json
{
"MaxNumTimesHelped": 5,
"AuthSecret": "FlfXgyRSwC2vPbLkaUP5"
}
MaxNumTimesHelped indicates how many times a student can get help over 24 hours, before they get rejected (see more info at the bottom).
AuthSecret is a random string used to hash passwords. Keep it random.
Running
You're done! Run the binary at $GOPATH/bin/210-queue-system to start serving incoming HTTP requests. It might be a good idea to host the application behind a HTTPS proxy, in order to
comply with the UBC data protection regulations.
What staff can do
TAs can use their credentials defined in authdb.json to perform the following operations:
TA control panel
TAs can access the panel while offering office hours, and mark students as 'served'. It is important that TAs mark students as served right away, so that wait time estimates are accurate.
JSON data dump
Instructors and TAs can download a dump of all the data contained in the database in JSON format.
This can be useful for data analysis purposes during/after the term.
To do so, just go to /jsondump after logging in from the web interface.

You can set a limit to the number of times a student can receive help over the range of 24 hours. Once this limit is reached, the student will read a message politely asking them to seek help elsewhere. You can set MaxNumTimesHelped to an insanely high number to disable this feature.
