Augustana CSC Q&A - Recent questions and answers in CSC 305 Fall 2024

Answered: Not a question, but this is a helpful resource we found!

Wed, 11 Dec 2024 19:37:25 +0000

Thanks for the resource!

Answered: How can you tell what the multiplicity of a class is for a UML diagram?

Wed, 11 Dec 2024 19:34:02 +0000

Generally the line between the classes will be labelled (like when we have a star or numbers) to show which class has one or many instances of another class.

Answered: When is a "has-a" relationship better to use than an "is-a" relationship?

Wed, 11 Dec 2024 19:31:52 +0000

"is-a" is a very specific link between 2 classes. It's when there is a clear hierarchical relation between the 2: one is a "subtype" of the other. Like how a Square is a Rectangle. It is really focused on code extension and inheriting both fields and behavior. "Has-a" is way more flexible and rather than making you inherit code or specific implementation it just gives a general idea of what behavior a class is supposed to be able to do but is not specific as to how that is done.

Answered: WPM Clarification

Wed, 11 Dec 2024 19:25:36 +0000

The WPM aspect can definitely be a complex concept to grasp especially since it seems that there is a lot of information online about this. What was suggested for us to keep it simple but understandable is to allow more space between entire character to be able to recognize when a character is done and not stretch out the time too much between the individual dit and dahs to the point where the user would be confused whether or not the silence is a space between character.

Answered: What was your default white noise volume? How did that affect the sound of the tone?

Wed, 11 Dec 2024 19:19:17 +0000

We had the static be by default less loud compared to the dit and dah sounds to be able to discern the transmission messages

Answered: What is the best way to show the morse and the actual english text together for the scenarios?

Wed, 11 Dec 2024 19:16:40 +0000

We had the user input be translated then displayed in english in a specific field on the screen if the user ticked a "show english translation" checkbox

Answered: What does git cherry-pick do?

Wed, 11 Dec 2024 13:47:03 +0000

git cherry-pick allows us to choose a commit from any one of the branches then append it to your current working head/ apply it.

Answered: What real-life scenarios should the AI bot simulate to make the learning experience feel authentic?

Wed, 11 Dec 2024 05:46:41 +0000

I think scenarios like using common CW signs to make them familiar to the real world, then some disaster scenarios where it is a bit longer to level up.

Answered: When would you choose to use an abstract class instead of an interface

Wed, 11 Dec 2024 05:37:37 +0000

An abstract class is preferred over an interface when you need a class that allows the sharing of common code functionality, with an inheritance concept in between classes like the is-a relationship, whereas interfaces implement the common functionality between closely related classes. Abstract classes are useful when you want to update a common behavior in the base abstract class it updates the inheriting classes as well.

Answered: How do I decide in the Strategy Pattern if a method should be abstract or encapsulated in an interface for flexibility?

Wed, 11 Dec 2024 05:22:14 +0000

I believe while using the strategy pattern while implementing both abstract classes and interfaces should be fine, depending on the amount of flexibility the method requires as in strategic patterns can change algorithms during runtime.

Answered: Anyone have a format they are using for the presentation?

Wed, 11 Dec 2024 03:49:00 +0000

For the presentation, you can start with the slide show explain the stuff on the slides then move on to the main live demo on the projector screen showing all the features in your project along with your group members. I think a brief presentation containing all the aspects in Memo 3B, would give sufficient time for the demo and for questions from the audience!

Answered: implementation of Server IP address

Wed, 11 Dec 2024 01:32:39 +0000

Given how we are not using multiple servers for this project and we are always connecting to the same IP address, hardcoding it seemed more intuitive for this case. As you mentioned, preventing running into an issue.

Answered: Have you filled out the IDEA form?

Tue, 10 Dec 2024 23:23:18 +0000

Yup all done!!

Answered: How can I make the Morse code sound fade out as the filter slider moves away from the sender's set frequency

Tue, 10 Dec 2024 23:22:59 +0000

The general logic here is that volume should decrease for every specific number of Hz away from receiver's frequency. I don't think the exact values were communicated so I think as long as you are doing this it's fine?

Answered: Filter and static volume

Tue, 10 Dec 2024 23:08:19 +0000

A narrower filter should reduce the amount of static, as well as affect what signals are received.

(In the real world, it's more complicated than just reducing the volume of the static, but that's a reasonable approximation to make for your apps.)

Answered: Presentation break down

Tue, 10 Dec 2024 23:05:20 +0000

Definitely spend more time on the demo!

Answered: What is the difference between git checkout/switch [branch] and git checkout [commit-hash]?

Tue, 10 Dec 2024 20:28:17 +0000

git checkout [branch] or git switch [branch] moves to a specific branch, making it the active branch for new commits.
git checkout [commit-hash] checks out a specific commit in a detached HEAD state, allowing you to view or work on that commit without affecting branches.
Use switch for branches as it's more explicit and avoids detached HEAD confusion.

Answered: What is the purpose of module-info.java and Maven?

Tue, 10 Dec 2024 20:26:41 +0000

module-info.java defines a module's dependencies, exports, and encapsulation in Java's module system for better modularity and security. Maven is a build automation tool that manages project dependencies, builds, and configurations using a standardized pom.xml file.

Answered: What is an example of encapsulation?

Tue, 10 Dec 2024 20:26:01 +0000

Encapsulation is the practice of bundling data and methods within a class and restricting direct access to some of its components. For example, in your Movie Tracker project, fields like title and genre in the Movie class are private, and public getters and setters control access.

Answered: What is the difference between GSON and JSON?

Tue, 10 Dec 2024 20:24:39 +0000

JSON (JavaScript Object Notation) is a lightweight data-interchange format used to store and transmit data.
GSON is a Java library by Google that converts Java objects to JSON and vice versa, providing tools to parse, generate, and manipulate JSON in Java applications

Answered: What is a JUnit?

Tue, 10 Dec 2024 20:23:54 +0000

JUnit is a Java testing framework used to write and run repeatable unit tests to ensure code correctness. It provides annotations and assertions to test individual components of your application efficiently.

Answered: What does git rebase do?

Tue, 10 Dec 2024 20:22:40 +0000

git rebase moves or replays your branch's commits onto another branch's tip, creating a linear history. It's useful for keeping a clean project history and integrating changes without a merge commit.

Answered: What is polymorphism? Is there an example of this somewhere in a project we have coded?

Tue, 10 Dec 2024 20:19:52 +0000

Polymorphism is an object-oriented programming concept where a single interface can represent different underlying forms (e.g., methods behaving differently based on the object they belong to). In your HighLowGUI game, the Card class could demonstrate polymorphism if a getValue() method behaves differently for various card types.

Answered: Speed control

Tue, 10 Dec 2024 20:03:36 +0000

For our project, we have it in the online mode, which is the server portion, in the settings popup window, which is used for single-person training, and also the chatbot. This way users have more control in both practice and training and change speed accordingly.

Answered: Tips for refactoring?

Tue, 10 Dec 2024 20:00:56 +0000

I think the best way to go about it would be to perform all the refactoring on a single computer if there is a lot that has to be done since merging would take a huge amount of time, or people could work on classes that are interrelated to one another so splitting work could happen.

Answered: use for a Q&A points grade calculator?

Tue, 10 Dec 2024 19:55:34 +0000

Thank you! This makes calculating super convenient!

Answered: Any ideas for Morse Code Training

Tue, 10 Dec 2024 19:50:44 +0000

For the Morse code training, users could practice it by typing alphabets or full words by giving them the option to do so similarly, while learning the audio aspect, the user could hear the CW code identify and write the correct letter or word. It would be nice to implement levels that users could advance to as they move further. Adding features like replay can be helpful so if they get it wrong; they can try again by listening to the sound again. Also, having a references button on the same page would be very convenient as they could revise while practicing.

Answered: What sound cues do you think could make HAM radio operations more intuitive?

Tue, 10 Dec 2024 16:48:56 +0000

I guess dits and dahs with the static noise too would be the closest to real HAM radio transmission.

Answered: How do you use a json message?

Tue, 10 Dec 2024 16:44:36 +0000

For the messages using the network it might be useful to also refer to the way Dr. Stonedahl did it and keep it as close as possible to the sample code, maybe that could help?

Answered: Presentation

Tue, 10 Dec 2024 16:02:49 +0000

We're thinking about doing something very simple as most of our presentation will be from our app so that we can demonstrate as many features as possible. But we will at least talk about the architecture of the code, include an UML diagram and discuss what we learned through this class and this project.

Answered: What’s the easiest way to enable and disable textfields?

Tue, 10 Dec 2024 07:02:15 +0000

You could set the textfield equal to the empty string? What are your goals?

Answered: How are you doing your UML diagrams for the presentation?

Tue, 10 Dec 2024 06:46:36 +0000

Are we supposed to make a general UML of the entire project or is it possible to only focus on a certain part/feature?

Answered: How do you set up the audio listener for message receiving and sending?

Tue, 10 Dec 2024 06:33:34 +0000

The ChatterBox example gives a good way of going about the server part. Going through it should give enough for what is required for the project without involving code that is too complex.

Answered: What aspects of sound quality are most important in HAM radio communication?

Tue, 10 Dec 2024 06:31:05 +0000

Dits and dots should be distinguishable + the pitch should match the convention

Answered: Websocket package not getting imported

Tue, 10 Dec 2024 06:28:23 +0000

We also had issues with IntelliJ about that. The pom.xml files + module-info files were all be updated but we still had to download documentation and refresh maven + just re-type the import statement and it just worked.

Can you share tips for implementing scalable WebSocket connections in a chatroom application?

Tue, 10 Dec 2024 05:22:02 +0000

Scaling Background Images

Tue, 10 Dec 2024 05:03:04 +0000

Does anyone know how to make images scale? Right now app works in full screen well but if you window it and make it smaller the background image stays full size so you just see a small section of it.

FXML Resizing

Tue, 10 Dec 2024 00:39:34 +0000

Hi guys,

We are adjusting our fxml pages in Scene Builder so that the UI is adjustable with changing window sizes (making windows full-screen). I have added all of the elements we were using into v-boxes and h-boxes in a border pane, which is displaying correctly in scene builder. However, whenever I launch our program I get a "no controller specified" error although I have not touched any code in Itellij or renamed pieces of the UI, I have only shifted elements in Scene Builder. Does anyone have some advice? Thank you

Do you know any tips for handling real-time data, like translating signals to text on the fly in Open AI?

Distortion in static

Thu, 05 Dec 2024 19:59:41 +0000

In memo 3A, we are supposed to allow more distortion and noise for advanced users. Is there another way in which we can create distortion in static without closing the audio line. I would like to multiple audio lines but it slows the app down alot

How do I solve the audio glitch that happens right when morse starts playing and sometimes all the way to the end

Thu, 05 Dec 2024 03:34:00 +0000

Ending Scenarios

Tue, 03 Dec 2024 21:28:48 +0000

How are the teams handling "ending" the Scenarios; Do you just stop after a certain time is up? Or does the user have to do something specific to reach a certain "goal"?

Pitch Distortion

Tue, 03 Dec 2024 20:40:16 +0000

What change to the pitch do we need to make if the frequency the user is on is smaller than the one the message is sent to and vice versa (Does the pitch go lower or higher)?

Scenarios Feature

Tue, 03 Dec 2024 20:38:25 +0000

How did you guys implement this feature? what I mean is did you make a separate part from the live ham radio and if so how does the user personalize the scenario and input the text for bots? Does the text the user inputs is just sent by bot at set interval or do you use listeners for specific words? if so how do you do that not knowing what type of scenario story the user wants to go with?

What is the best way to set up the speed controller?

Tue, 03 Dec 2024 19:44:00 +0000

On the LCWO website, there is an effective and a character speed controller. Should I also use an effective and a character speed controller? I feel like character speed doesn't really make sense since, according to Dr. Vincent, the length of the dits and the dahs are supposed to stay always the same.

What are the prompts you all are feeding the bot in order to have it communicate with the Users?

Tue, 03 Dec 2024 19:33:26 +0000

With the Server work, does anyone have an easier guide than the website professor provided?

Tue, 03 Dec 2024 19:32:10 +0000

good tutorial of Java Audio API for fine tuning pitch/frequency and duration of the sound

Tue, 03 Dec 2024 19:25:00 +0000

Im not 100% confident in my understanding of how these things work and I can't find a very comprehensive tutorial.

What sound files do you use?

Tue, 03 Dec 2024 17:42:16 +0000

Our sound file is extremely scratchy and does not translate well with spacing. What sound files did everyone else use to get a higher-quality sound?

Does anyone have recommendations for resources or guides on using AI APIs to build bots?
