Hey I got reminded of a funny story.
A friend of mine and me were in internships in the same company. The company was specialized in territory resources management (managing water for agriculture, money to build industrial zones...). He got the interesting internship (water predictory modeling) and I got... The repairs of a reference sheet manager that never happened to work. It was in C# and ASP.NET and I was in second year of CS. I expected the code to be nice and clear since it was made by a just graduated engineer with +5years of studies.
I was very wrong.
This guy may never have touched a web server in his life, used static variables to keep sessions instead of... well... sessions, did code everything in the pages event handlers (even LinQ stuff et al) and I was told to make it maintainable, efficient and functional in 2 months. There were files with +32k LoC.
After 1week of immense despair, I decided I will refactor all the code. Make nice classes, mapping layer, something close to a MVC... So I lost time and got scoled for not being able to make all the modifications as fast as in a cleanly designed code...
After 4 weeks, everything was refactored and I got to wait for the design sheets to change some crystal report views.
At this moment I began to understand were was the problem in this company.
My friend next door got asked to stop his modeling stuff for an emergency project. He had to make an XML converter for our clients to be able to send decentralized electrics bills, and if it was not completed within a week, they would no longer be able to pay until it is done.
This XML converter was a project scheduled 5 years before that. Nobody wanted to do it.
At the same time, I was waiting for the Com Department to give me the design views.
I never saw the design views. Spent one month implementing a golden ratio calculator with arbitrary precision because they ain't give me anything to do until the design were implemented.
Ended with a poor grade because "the work wasn't finished".2 -
Let's talk about input forms.
Please don't do that!
Setting time with the arrow buttons in the UI.
Each time change causes the page to re-fetch all the records. This is fetching, parsing, rendering tens of thousands of entries on every single click. And I want to set a very specific time, so there's gonna be a lot of gigs of traffic wasted for /dev/null.
Do I hear you say "just type the date manually you dumbass!"? I would indeed be a dumbass if I didn't try that. You know what? Typing the date in manually does nothing. Apparently, the handler is not triggered if I type it in manually/remove the focus/hit enter/try to jump on 1 leg/draw a blue triangle in my notebook/pray3 -
EoS1: This is the continuation of my previous rant, "The Ballad of The Six Witchers and The Undocumented Java Tool". Catch the first part here: https://devrant.com/rants/5009817/...
The Undocumented Java Tool, created by Those Who Came Before to fight the great battles of the past, is a swift beast. It reaches systems unknown and impacts many processes, unbeknownst even to said processes' masters. All from within it's lair, a foggy Windows Server swamp of moldy data streams and boggy flows.
One of The Six Witchers, the Wild One, scouted ahead to map the input and output data streams of the Unmapped Data Swamp. Accompanied only by his animal familiars, NetCat and WireShark.
Two others, bold and adventurous, raised their decompiling blades against the Undocumented Java Tool beast itself, to uncover it's data processing secrets.
Another of the witchers, of dark complexion and smooth speak, followed the data upstream to find where the fuck the limited excel sheets that feeds The Beast comes from, since it's handlers only know that "every other day a new one appears on this shared active directory location". WTF do people often have NPC-levels of unawareness about their own fucking jobs?!?!
The other witchers left to tend to the Burn-Rate Bonfire, for The Sprint is dark and full of terrors, and some bigwigs always manage to shoehorn their whims/unrelated stories into a otherwise lean sprint.
At the dawn of the new year, the witchers reconvened. "The Beast breathes a currency conversion API" - said The Wild One - "And it's claws and fangs strike mostly at two independent JIRA clusters, sometimes upserting issues. It uses a company-deprecated API to send emails. We're in deep shit."
"I've found The Source of Fucking Excel Sheets" - said the smooth witcher - "It is The Temple of Cash-Flow, where the priests weave the Tapestry of Transactions. Our Fucking Excel Sheets are but a snapshot of the latest updates on the balance of some billing accounts. I spoke with one of the priestesses, and she told me that The Oracle (DB) would be able to provide us with The Data directly, if we were to learn the way of the ODBC and the Query"
"We stroke at the beast" - said the bold and adventurous witchers, now deserving of the bragging rights to be called The Butchers of Jarfile - "It is actually fewer than twenty classes and modules. Most are API-drivers. And less than 40% of the code is ever even fucking used! We found fucking JIRA API tokens and URIs hard-coded. And it is all synchronous and monolithic - no wonder it takes almost 20 hours to run a single fucking excel sheet".
Together, the witchers figured out that each new billing account were morphed by The Beast into a new JIRA issue, if none was open yet for it. Transactions were used to update the outstanding balance on the issues regarding the billing accounts. The currency conversion API was used too often, and it's purpose was only to give a rough estimate of the total balance in each Jira issue in USD, since each issue could have transactions in several currencies. The Beast would consume the Excel sheet, do some cryptic transformations on it, and for each resulting line access the currency API and upsert a JIRA issue. The secrets of those transformations were still hidden from the witchers. When and why would The Beast send emails, was still a mistery.
As the Witchers Council approached an end and all were armed with knowledge and information, they decided on the next steps.
The Wild Witcher, known in every tavern in the land and by the sea, would create a connector to The Red Port of Redis, where every currency conversion is already updated by other processes and can be quickly retrieved inside the VPC. The Greenhorn Witcher is to follow him and build an offline process to update balances in JIRA issues.
The Butchers of Jarfile were to build The Juggler, an automation that should be able to receive a parquet file with an insertion plan and asynchronously update the JIRA API with scores of concurrent requests.
The Smooth Witcher, proud of his new lead, was to build The Oracle Watch, an order that would guard the Oracle (DB) at the Temple of Cash-Flow and report every qualifying transaction to parquet files in AWS S3. The Data would then be pushed to cross The Event Bridge into The Cluster of Sparks and Storms.
This Witcher Who Writes is to ride the Elephant of Hadoop into The Cluster of Sparks an Storms, to weave the signs of Map and Reduce and with speed and precision transform The Data into The Insertion Plan.
However, how exactly is The Data to be transformed is not yet known.
Will the Witchers be able to build The Data's New Path? Will they figure out the mysterious transformation? Will they discover the Undocumented Java Tool's secrets on notifying customers and aggregating data?
This story is still afoot. Only the future will tell, and I will keep you posted.6 -
So many years ago while I was in college learning to code and interning as a developer working on a javascript based image designer. We were learning event handlers in class and I was learning how to work with jQuery.
So I decided to build an event handlers to move objects by key press. I had an afternoon free and dont remember merging it to the codebase.
A few months later, something was pushed that took key press the event handler and the testers complained about losing the event handler I made.
End of the story, I added a feature that is still being used because I wanted to learn how to do something. -
When you are trying to write event handlers in JavaScript and nothing is working so you spend hours and hours trying to figure out what the fuck is wrong with your js code only for it to be a duplicate id. Fuck sake. I really wish JavaScript warned you about duplicate ids, but then again that's what you get for using such a weakly typed language.

I feel like being expected to handcode a user interface by supposed progressives is the most ass backwards idiotic tech decision with long and wide ranging consequences anyone ever farted out of the asshole god bored into their ugly faces!
Why the hell would I want to use web when I could use windows forms ?
Why is there no equivalent to the visual designer that's usuable ?
I mean I get it for more customized things
But why would I want to fuck with css when instead I could do about the same thing and store them in a settings file and point and click on a series of dropdowns and see the results as I create them ?
Why would I want to fuck around with an interface a resize destroys ?
Why would I want to mess with html tagging or tk or tcl containers when I could just drag an item into a window and update it's properties and add some fucking event handlers the stubs of which are automatically generated by a single DoubleClick??!!??
I hate it
It's slow
I want my fucking ui to be done quickly !
Am I just missing some vital tool that costs 5 grand ?16 -
There is little as delightful as opening an old VB.net application to find that there's fifty obscurely named event handlers - each with their own block of largely duplicated (but subtly and crucially different) code

So for the special kind of event handlers that runs before an event, would you prefer the react style "will" as in "onWillChange", or the W3C style "before" as in "onbeforeunload"?5

Wasted over two hours today on a stupid bug: for some reason, every event was handled two times on my local machine.
Why? Because although all services are readonly after instantiation, the EventDispatcher isn't: it is modified when registering event handlers. Meaning the very same instance of the actual EventSubscriber was reused for the async- and sync event dispatcher. Which are just simple wrappers for primary and secondary use cases, but use the _same_ instance of the actual EventSubscriber in my dev-environment as I now know.
Thankfully a shallow clone did the trick. Of course it would be possible to simply create a new instance, but this is one of the few services which are autoconfigured by the framework.
Don't know what to make of this to be honest. "Play stupid games, win stupid prizes!" I guess...
