I have a assignment where I have to convert some Java code with multiple classes and functions to a sequence diagram. I was wondering what are some good resources(websites/videos) to reference for converting already completed code to a sequence diagram. I’m having trouble finding help that doesn’t involve programs that just do it for you.

I moved to Mobile Programming (Enterprise) from the days of C++/Objective-C on macOS and Linux machines. UML, Sequence diagrams used to be very helpful to understand the project across teams and work together. Also with-in the teams. It is like another spoken language for engineers.

I am not seeing that anywhere now. I worked for some big companies while I was consulting - and they seldom using them. At least UML and Sequence diagrams. I see downsides of not using them in current days projects. Engineers are often mis-informed because there is no proper technical documentation. Everything is in “stories”, everything is in “JIRA Confluence”.

I proposed UML and Sequence diagrams. Most of the recent engineers did not agree with that. I spent so much time in preparing the presentation and history of it. But everyone denied. The Product Managers unanimously said NO. I learnt they did not really focus on those subjects or did not even learn them.

I still feel they are very relevant and robust for current and modern projects too.

1. It communicates in better pictorial languages
2. Everybody would be on same page and understands it same way because it is not plain english or a JIRA story.
3. Once you document it and lock it, it is same across the teams.
4. Instead of reading the code, you can just see the diagrams and understand logic, class hierarchy. Also how many really are documenting their code. If Sequence diagrams or class diagrams are implemented, these would help a lot.
5. Projects could be maintained so well with this. Even if some coders left the team, the new engineers can just go through these and learn.

I am wondering if any of your projects are using UML and Sequence diagrams.

You can also add prefix or suffix options for insert your diagram to your codes.

Hi,

In my current job, I try to use different modeling diagrams just in order for it to make sense and improve the overall understanding and processes.

Although it's acceptable in the company, it's not widely used and in my project team, the software engineers, HW engineers, product managers, and sometimes other SEs that I work with from other divisions don't really understand why I "waste time" on it.

But, objectively looking at it, it did change a few approaches and the overall architecture we had by explaining and presenting it to others, it helped convey the flow of actions and different motivations.

The thing is that there is a tension between spending time on doing modeling and really digging deep on how to implement processes, and between just working and continuing the day-to-day tasks because we have requirements, the schedule is tight and there's no time to waste.

Has it happened to anyone else?

Thanks.

Is there a book on surgery for each procedure and you read it 60 times? Or do you bring a reference book with you into the surgery? Who sits around turning the pages for you?

I doubt it’s anything like that.

basically im working on my masters degree and doing full time dev work too. Where I work we dont really use diagrams, once we get the requirements done we start work soon as those hit our desks. I'll admit we probably do do things a bit differently, we've been using computers and programming stuff since about when the first univac started getting sold to businesses(I've been told we started using univac here in 1952 or 1953). So yeah we had our own standards since before the big standards became mainstream. For the most part we've moved on to adopt the mainstream standards here though. But yeah we dont really use the diagrams here, we get the requirements and start work.

I told my software engineering teacher about this and she was horrified, saying thats not good practice etc. But shes also never worked a day in the real world, just academia. So Im not sure what other real world businesses do.

Do most businesses use the class and sequence diagrams? Does the one you work for? Or is that mostly a thing they just teach in school

Hi there! does anyone know how to do a sequence diagram from an extended use case event?

I added a few things to Code Video Generator for version 0.3, including animated sequence and box diagrams, demoed in the video above. If you are interested in how it works, the example for the sequence diagram looks like this:

diagram = AutoScaled(SequenceDiagram())
browser, web, app = diagram.add_objects("Browser", "Web", "App")
with browser:
    with web.text("Make a request"):
        web.to_target("Do a quick thing", app)
        with app.text("Retrieve a json object"):
            app.to_self("Calls itself")
            app.note("Do lots and lots and lots of thinking")
            app.ret("Value from db")
        web.ret("HTML response")
title = Text("Sequence Diagram")
title.to_edge(UP)
self.add(title)
diagram.next_to(title, DOWN)
self.play(ShowCreation(diagram))
for interaction in diagram.get_interactions():
    self.play(ShowCreation(interaction))

CODE AND DATA

This is the code behind HR. Data were taken from Gaia's 2nd data release and SDSS, crossmatched to within 3 arcsec radius. The sample includes all stellar spectra within 200 parsecs with a S/N > 30.

PLOT DESCRIPTION

The axes in the "HR" (for Hertzsprung Russell) plot are actually color and absolute magnitude, normally refered to as a color-magnitude diagram. The y-axis corresponds to luminiosity and the x-axis corresponds to temperature. Left to right is hotter to colder, bottom to top is dimmer to brighter. The bottom plot is the spectrum of the star under your cursor. It's the intensity of each wavelength of light emitted by the star.

COOL FEATURES

• Most stars have a black body emission curve and absorption lines on top due to cooler atmospheric layers outside of their hot cores. Some of them even have emission lines due to a hotter exterior! Can you identify the ones that do? What do they have in common?
• Notice the main blob that goes from bottom right to top middle. This is the main sequence. As stars age, they move up the main sequence.
• Look at the bottom left corner. Those are the spectra of white dwarfs. They have clear, broad lines, compare them with other stellar spectra in the main sequence. The lines in white dwarfs are broader. White dwarfs have higher surface gravity, which means they have higher pressures, which scatters the electrons around and broadens their lines. The lowest white dwarfs are cooler and have narrower (or even hidden) absorption lines.
• Looking at the main sequence: Stars with lower temperatures are redder, to the right, and stars with higher temperatures are bluer, to the left. Lower temperature stars have more molecular aborptions lines, which are much wider dips than element lines. Can you identify them? They correspond to red dwarfs within the main sequence.
• Look at the spectra of white dwarfs and then that of red dwarfs (the bottom part of the main sequence). Now loo

So normally in the title sequence the last picture before the logo is always the main subject in the episode.

Except for the past two episodes, it hasn't. Two weeks ago it showed the TikTok logo as the last picture (for the US scandal and banning the app), but then the main story was about China and the Uighurs.

It happened last night too; last night it was a mailbox (for Trump sabotaging the USPS, and by extension voting by mail), but then the main story was about juries!

Have they been changing the main stories last minute? What the hell is happening?
