Do NOT build something as fast as possible. You are going to end up spending more time trying to refactor the mess than youd have spent drawing a class diagram.7

Me: Enters SQL class
Prof: We will draw ERD diagram on awwapp
Me: (In my head - I hate ERD diagrams) start drawing the first ERD diagram
Prof: That diagram is wrong
Prof: opens SQL Activities_Solution.pdf on his PC
Me: Tried to change the file name on aws to get solution file - fail
Copy SQL Activities.pdf file url (https://url/courses/6429/...). Adds 1 to 1100726 = 1100727 and downloads SQL Activities_Solution.pdf
Open PDF in one tab and awwapp on another and just draw the solution
Prof: Are you sure this diagram is corect?
Me: (In my head - I copied the solution so yes) ...
Prof: Let me check the question
Me: (In my head - seriously? you don't know the answer)
Prof: Checks the correct answer on his PC and then checks the answer on my PC
Me: (In my head - completed another boring uni class) pack up and go home8 -
Fucking teammate who did not know how to read/write a simple class diagram.
We warned him that he have to study or we just kick his fucking ass out of the team.
He just did nothing. When we had meetings he just stayed at home pretending to have an heart issue needing surgery.
After just 2-3 days he was tagged on FB in a photo shooted a few days earlier where he was riding a bike for a competition.
He skipped another scheduled-a-fucking-week-before meeting saying that he was on a surprise trip, when I called him 5 minutes before meeting start.
In the end we just kick him out because he did nothing. He went to professor talking about some relationship problem in the team and asked him if he could continue the project by himself just forking the ours.
Professor said HELL NO SON OF A BITCH.
But our team learned a precious lesson : choose your team carefully.5 -
So, I was gonna rant about how it can be difficult to design event-based Microservices.
I was gonna say some shit about gateways APIs and some other stuff about data aggregation and keeping things idempotent.
I was going to do all this but then as I was stretching out the old ranting fingers I decided to draw a diagram to maybe go along with the rant.
Now I’m not here to really rant about all that Jazz...
I’m here to give you all a first class opportunity to tear apart my architecture!
A few things to note:
Using a gateway API (Kong) to separate the mobile from the desktop.
This traffic is directed through to an in intermediate API. This way the same microservices can provide different data, and even functionality for each device.
Most Microservices currently built in golang.
All services are event based, and all data is built on-the-fly by events generated and handled by each Microservices.
RabbitMQ used as a message broker.
And finally, it is hosted in Google Cloud Platform.
The currently hosted form is built with Microservices but this will be the update version of things.
So, feel free to rip it apart or add anything you think should change.
Also, feel free to tell me to fuck right off if that’s your cup of tea as well.
Peace ✌🏼19 -
Right now, we are playing a game, where we have to do a UML-Class-Diagram for a Gift-Management-Software for Santa Claus.
College, go figure.5 -
So, this is probably somewhat esoteric but...
While studying at university I had a "programming paradigms" module, dunno why they called it that, it was more like "introduction to functional programming".
So, it's kinda mind bending, we'd only really started to get our heads around classical object oriented programming and they throw functional programming at us.
It's worse than that though, for do they use an established language, like lisp/scheme, functional Python, or even given Haskell?
No, of course they didn't. They taught us Oz.
You probably won't have heard of it, but this language is burned into the back of my brain, along with a vague understanding of the n-queens problem we had to solve graphically (using qTk, which I dunno if someone took qt and tk and blended them, I stopped asking questions after a while).
To top it off did this language (at the time) have a stand alone interpreter? Did it buggery! It was coupled to the Mozart programming system, which is just Emacs (which has a bloody lisp built into it,so close, yet so far 😭).
It gets worse, though, oh does it get worse, for pause dear reader and consider, have you ever heard of Mozart/oz before, I'd put money on most of you had not heard of it until today.
For, you see, I believe at the time of writing, one, yes, ONE text book exists on this language. When I was doing my assignment there was merely some published conference notes and language design documents.
That's not all, I was not the only one experiencing difficulties with this language, someone in the class ended up pouring through the mailing lists and found the very tutor teaching the class struggling at first to understand the language.
I had to repeat that year. The functional programming class was one semester.
When I retook that year, it was a whole year long. However, halfway through the year, original tutor was fired and a new tutor was hired to teach the language.
He was, understandably, just as confused as we were.
There was a Starbucks and a pub equidistant from the lecture hall, though in opposite directions. From lecture to lecture we had no idea which one we'd end up in.
I have reason to believe Mozart/Oz it some sort of otherworldly abomination designed to give students the occasional nightmare flashback, long after they've left.
My room had post it notes, sheets of paper, print outs, diagrams, doodles and pens, just stuck to the wall, I looked like a raving lunatic three hours away from being institutionalised. There was string connecting one diagram to the next and images of a chess queen all over. As I attempted to solve the n-queens problem.
Madmans knowledge, I call it. I can never unlearn all that, in fact it seeps into much of the code I write. Such information was not meant for the minds of a simple country bumpkin such as myself...
Mozart/Oz... I wouldn't be the programmer I am today without it, and that's frankly terrifying...10 -
daily.
me: i looked into the customer dev's project and even though it's C#, i can use it as a source of inspiration for my own C++ library.
PM: okay, maybe we can even still use it, so that you use a C# dll with your C++ code.
me: ...
other colleague: that's a bad idea. it can already be a challenge to use unmanaged c++ in dotnet, but the other way round it's even more difficult. C# and C++ are languages that behave quite differently and it will be hard to implement a correctly working interface.
PM: okay. well... then please analyze this project's complexity in terms of LOC and create a class diagram, so we get an idea of how complex it is.
me: sure.
PM: hmm... maybe we should split this topic. since dev x will also rely on your library, analyze this project together with him, each of you look at another part of the classes.
me: that's.... i think that's a bad idea. implementing this functionality in this library is my job, not of dev X. he won't be involved in implementing any of the funcionalities and for him, it shouldn't matter how this works.
PM: yeah, but since we are prototyping, maybe we should just violate the "separation of concerns" rule.
me (internally): (ノಠ益ಠ)ノ彡┻━┻
in the end i could convince him to do it my way, but for fuck's sake... when was the last time he actually succesfully implemented something? 🤦♀️ -
Long time no rant.
Here's the summary of a review meeting I & team just had with our programming prof:
"You did exactly what I taught you in class, and I don't like it."
"To get a better mark you should've done more than what was required."
"This wasn't a requirement. You should've kept it short."
except we asked about it being a requirement earlier and only got vague answers like "that should be obvious."
Also, printing a class diagram over 2 pages apparently is unacceptable and we should've gone to a copyshop to print that as one page instead.1 -
Holy shit sometimes I hate my job. Current assignment: translate a C++ COM class to C#. Requirement: interface should not change. I ask the other team using this interface to ask me any questions so I can address their concerns. First FUCKING thing they ask for: a diagram explaining how to access the interface. For. Fuck. Sake. The goddamn thing is not changing. At all. I have said that to every stakeholder every time. It's a changed reference and a tweak to some calls to make them .Net calls. Why am I redocumenting something that was documented years ago?2

I asked at an interview if they documented their code with class diagrams.
One of the interviewers told me: "Good code doesn't need a class diagram"

*TRIGGERED*4 -
I have just slept for a minimum of 5 hours. It is 7:47 PM atm.
Why?
We have had a damn stressful day today.
We have had a programming test, but it really was rather an exam.
Normally, you get 30 minutes for a test and 45 minutes for an exam.
In this "test" we have had to explain what 'extends' does and name a few advantages of why one should use it.
Check.
Read 3 separate texts and write the program code on paper. It was about 1 super class and 1 sub class with a test class in Java.
Check.
Task 3: Create the UML diagram of the code from above. *internally: From above? He probably means my code since there is no other code there. *Checks time*. I have about 3 minutes left. Fuck my life.*
Draws the boxes. Put the class names in each of them. A private attribute for the super class.
Teacher: Last minute!
Draw the arrow starting starting from the sub class to the super class.
Put my name on each written paper. And mentally done for the day. Couldn't finish the last task. Task 3.
During this "test", I heard the frustrations of my classmates. Seemed like everyone was pretty much pissed.
After a short discussion with the teacher who also happens to be the physics professor of a university nearby.
[If you are reading this, I hope that something bad happens to you]
The next course was about computer systems. Remember my recent rant about DNS, dhcp, ftp, web server and samba on ubuntu?
We have had the task to do the screenshots of the consoles where you proof that you have dhcp activated on win7 machine etc. Seemed ok to me. I would have been done in 10 minutes, if I would be doing this relaxed. Now the teacher tells us to change the domain names to <surnameOfEachStudent>.edu.
I was like: That's fine.
Create a new user for the samba server. Read and write directories. Change the config.
Me: That should be easy.
Create new DNS entries in the configs.
Change the IPv6 address area to 192.168.x.100-200/24 only for the dhcp server.
Change the web server's default page. Write your own text into it.
You will have 1 hour and 30 minutes of time for it.
Dumbo -ANGRY-CLIENT-: Aye. Let us first start screenshotting the default page. Oh, it says that we should access it with the domain name. I don't have that much time. Let us be creative and fake it, legally.
Changes the title element so that it looks like it has been accessed via domain name. Deletes the url and writes the domain name without pressing Enter. Screenshot. Done. Ok, let us move to the next target.
Dhcp: Change lease time. Change IP address area. Subnet mask. Router. DNS. Broadcast. Optional domain name. Save.
Switches to win7.
ipconfig /release
ipconfig /renew
Holy shit it does not work!
After changing the configs on ubuntu for a legit 30 minutes: Maybe I should change the ip of the ubuntu virtual machine itself. *me asking my old self: why did not you do that in the first place, ass hole?!*
Same previous commands on win7 console. Does not work. Hmmm...
Where could be the problem?
Check the IP of the ubuntu server once again. Fml. Ubuntu did not save when I clicked on the save button the first time I have changed it. Click on save button 10 times to make sure it really is saved now lol.
Same old procedure on win7.
Alright. Dhcp works. Screenshot.
Checks time. 40 minutes left.
DNS:It is your turn. Checks bind9 configs. sudo nano db.reverse.edu.
sudo nano db.<mysurname>.edu.
Alright. All set. It should work now.
Ping win7 from ubuntu and vice versa. Works. Ping domain name on windows 7 vm. Does not work.
Oh, I forgot to restart the bind9 server on ubuntu.
sudo service bind stop
" " " start
Check DNS server IP on win7. It looks fine.
It still doesn't work. Fuck it. I have only 20 minutes left. Samba. Let us do this!
10 minutes in. No result. I don't remember why. I already forgot why I have done for it. It was a very stressful day.
Let us try DNS again.
Oh shit. I forgot the resolver!
sudo nano /etc/resolv.conf
The previous edits are gone. Dumb me. It says it in the comments. Why did not I care about it. Fuck it.6 minutes left. Open a yt video real quick. Changes the config file. Saves it. Restarts DNS and dhcp. Closes the terminal and opens a new one. The changes do not affect them until you reopen them. That's why.
Change to win7.
Ping works. How about nsloopup.
Does not work.
Teacher: 2 minutes left!
Fuck it.
Saves the word document with the images in it. Export as pdf. Tries to access the directories of the school samba server. Does not work. It was not my fault tho. Our school server is in general very slow. It feels like they are not maintained and left alone like this in the dust from the 90s.
Friend gets the permission to put his document on a USB and give the USB to the teacher.
Sneaky me: Hey xyz, can you give me your USB real quick?
Him: sure.
Gets bombed with "do you want to format the USB?" pop-ups 10 times. Fml. Skips in a fast way.
Transfers the pdf. Plug it out. Give it back.
After this we have had to give a presentation in politics. I am done.6 -
I want to read a good Software Engineering book. A modern one, which contains new agile approaches, useful diagrams, etc. Not the classical, not so useful, class diagram.
What do you recommend? I'm currently more into web and mobile apps, and I want to be able to describe my backend and frontend with useful diagrams which describe better to users and other developers my desired design. -
I figured I would share my Capstone from this semester with a community that might be interested. An eclipse plugin that was developed in our lab is able to implicitly track developer eye gazes as they work in an IDE (eclipse in this case). Before I began work on it, source code, bug reports, and stack overflow documents could be tracked with all of the data on said documents being extracted. For example, if source code is being tracked, everything from the file name and class/method name down to statement types are collected. The tracking isn't on still images. Since it's within an IDE, you can open multiple files, scroll, and modify -- all while tracking is collecting accurate data based on the (x, y) gaze coordinate and the handler assigned to the type of document/file being viewed.
My job was to extend this functionality to track gazes on UML class diagram documents. This means I had to gather data at the highest level: the class/connection being looked at, down to the lowest level: members/methods, their types and containing classes.
Being new to Java's EMF, GEF, and eclipse plugin development, I had a bit of a learning curve. Anyways here is the poster of the functionality I added. 🙃
Not much of a rant haha. -
As a student, I really do understand the need for the diagrams made for a system, diagrams such as
ER Diagram
Use case Diagram
Class Diagram
etc
Like it's literally pointless...6 -
<rant>
So we've been doing the final project for college which has 2 parts
1. preparation of a project
2. creating an application
The first part wasn't a problem, making UML diagrams(ERD, Class Diagram, Use case) and SCRUM related documents.
But BLOODY FUCKING HELL was the second part bad.
You get a premade preparation for the second part of the exams... it was the most disturbing thing ever! The ERD which you have to follow is entirely made out of varchars, terribly built for the system you're creating by the way.
We ended up being able to use our own preparation instead after going back and forth... but damn. A company makes these things and the government pays millions for it! What the fuck are they doing? Hiring third graders to play around with lines??
No wonder IT is looked down upon in the Netherlands.. the government is entirely at fault due to their terribly outdated exams, projects, etc.
I thought i had seen it all... but holy fucking shit
</rant> -
Control projects already realized
Design in Figma and Prototyping
Class diagram
code
*I wake up from sleep* -
When all the feedback you get from a damned class diagram was "Ok looks good :)"
Not sure if good because it doesn't look like a complicated cobweb anymore or because the relationships established were right - though I doubt you can say that just by looking for a mere 30 seconds at a class diagram with more than 20 classes.
