What kinda system is that -_-12 -
So a user reported they couldn't login to our site, so I reset their password to:
uI+ffRT7M2NAzo8uOqzf4QxO3I9tj8PJ4TS0n8zDV7I
And sent them back an email with the updated password. A few minutes later, they replied and said that password didn't work. They even tried a different web browser, etc. I tried it myself, and sure enough, it didn't work.
I spent the next several hours trying to figure out why the password didn't save properly, or why the logic didn't compare them correctly. Perhaps it was some sort of caching issue? Oh the horror.
As it turns out, the problem was a maxlength of 28 on the login form field:
<input type="password" name="password" value="" maxlength="28"/>
I don't know who wrote that code, but it sure wasn't me.21 -

> Root struggles with her ticket
> Boss struggles too
> Also: random thoughts about this job
I've been sick lately, and it's the kind of sick where I'm exhausted all day, every day (infuriatingly, except at night). While tired, I can't think, so I can't really work, but I'm during my probationary period at work, so I've still been doing my best -- which, honestly, is pretty shit right now.
My current project involves legal agreements, and changing agent authorization methods (written, telephone recording, or letting the user click a link). Each of these, and depending on the type of transaction, requires a different legal agreement. And the logic and structure surrounding these is intricate and confusing to follow. I've been struggling through this and the project's ever-expanding scope for weeks, and specifically the agreements logic for the past few days. I've felt embarrassed and guilty for making so little progress, and that (and a bunch of other things) are making me depressed.
Today, I finally gave up and asked my boss for help. We had an hour and a half call where we worked through it together (at 6pm...). Despite having written quite a bit of the code and tests, he was often saying things like "How is this not working? This doesn't make any sense." So I don't feel quite so bad now.
I knew the code was complex and sprawling and unintuitive, but seeing one of its authors struggling too was really cathartic.
On an unrelated note, I asked the most senior dev (a Macintosh Lisa dev) why everything was using strings instead of symbols (in Rails) since symbols are much faster. That got him looking into the benchmarks, and he found that symbols are about twice as fast (for his minimal test, anyway), and he suggested we switch to those. His word is gold; mine is ignorable. kind of annoying. but anyway, he further went into optimizing the lookup of a giant array of strings, and discovered bsearch. (it's a divide-and-conquer lookup). and here I am wondering why they didn't implement it that way to begin with. 🙄
I don't think I'm learning much here, except how to work with a "mature" codebase. To take a page from @Rutee07, I think "mature" here means the same as in porn: not something you ever want ot see or think about.
I mean, I'm learning other things, too, like how to delegate methods from one model to another, but I have yet to see why you would want to. Every use of it I've explored thus far has just complicated things, like delegating methods on a child of a 1:n relation to the parent. Which child? How does that work? No bloody clue! but it does, somehow, after I copy/pasted a bunch of esoteric legacy bs and fussed with it enough.
I feel like once I get a good grasp of the various payment wrappers, verification/anti-fraud integration, and per-business fraud rules I'll have learned most of what they can offer. Specifically those because I had written a baby version of them at a previous job (Hell), and was trying to architect exactly what this company already has built.
I like a few things about this company. I like my boss. I like the remote work. I like the code reviews. I like the pay. I like the office and some socializing twice a year.
But I don't like the codebase. at all. and I don't have any friends here. My boss is friendly, but he's not a friend. I feel like my last boss (both bosses) were, or could have been if I was more social. But here? I feel alone. I'm assigned work, and my boss is friendly when talking about work, but that's all he's there for. Out of the two female devs I work with, one basically just ignores me, and the other only ever talks about work in ways I can barely understand, and she's a little pushy, and just... really irritating. The "senior" devs (in quotes because they're honestly not amazing) just don't have time, which i understand. but at the same time... i don't have *anyone* to talk to. It really sucks.
I'm not happy here.
I miss my last job.
But the reason I left that one is because this job allows me to move and work remotely. I got a counter-offer from them exactly matching my current job, sans the code reviews. but we haven't moved yet. and if I leave and go back there without having moved, it'll look like i just abandoned them. and that's the last thing I want them to think.
So, I'm stuck here for awhile.
not that it's a bad thing, but i'm feeling overwhelmed and stressed. and it's just not a good fit. but maybe I'll actually start learning things. and I suppose that's also why I took the job.
So, ever onward, I guess.
It would just be nice if I could take some of the happy along with me.7 -
I wrote a database migration to add a column to a table and populated that column upon record creation.
But the code is so freaking convoluted that it took me four days of clawing my eyes out to manage this.
BUT IT'S FINALLY DONE.
FREAKING YAY.
Why so long, you ask? Just how convoluted could this possibly be? Follow my lead ~
There's an API to create a gift. (Possibly more; I have no bloody clue.)
I needed the mobile dev contractor to tell me which APIs he uses because there are lots of unused ones, and no reasoning to their naming, nor comments telling me what they do.
This API takes the supplied gift params, cherry-picks a few bits of useful data out (by passing both hashes by reference to several methods), replaces a couple of them with lookups / class instances (more pass-by-reference nonsense). After all of this, it logs the resulting (and very different) mess, and happily declares it the original supplied params. Utterly useless for basically everything, and so very wrong.
It then uses this data to call GiftSale#create, which returns an instance of GiftSale (that's actually a Gift; more on that soon).
GiftSale inherits from Gift, and redefines three of its methods.
GiftSale#create performs a lot of validations / data massaging, some by reference, some not. It uses `super` to call Gift#create which actually maps to the constructor Gift#initialize.
Gift#initialize calls Gift#pre_init (passing the data by reference again), which does nothing and returns null. But remember: GiftSale inherits from Gift, meaning GiftSale#pre_init supersedes Gift#pre_init, so that one is called instead. GiftSale#pre_init returns a Stripe charge object upon success, or a Gift (and a log entry containing '500 Internal') upon failure. But this is irrelevant because the return value is never actually used. Pass by reference, remember? I didn't.
We're now back at Gift#initialize, Rails finally creates a Gift object using the args modified [mostly] in-place by all of the above.
Another step back and we're at GiftSale#create again. This method returns either the shiny new Gift object or an error string (???), and the API logic branches on its type. For further confusion: not all of the method's returns are explicit, and those implicit return values are nested three levels deep. (In Ruby, a method will return the last executed line's return value automatically, allowing e.g. `def add(a,b); a+b; end`)
So, to summarize: GiftSale#create jumps back and forth between Gift five times before finally creating a Gift instance, and each jump further modifies the supplied params in-place.
Also. There are no rescue/catch blocks, meaning any issue with any of the above results in a 500. (A real 500, not a fake 500 like last time. A real 500, with tragic consequences.)
If you're having trouble following the above... yep! That's why it took FOUR FREAKING DAYS! I had no tests, no documentation, no already-built way of testing the API, and no idea what data to send it. especially considering it requires data from Stripe. It also requires an active session token + user data, and I likewise had no login API tests, documentation, logging, no idea how to create a user ... fucking hell, it's a mess.)
Also, and quite confusingly:
There's a class for GiftSale, but there's no table for it.
Gift and GiftSale are completely interchangeable except for their #create methods.
So, why does GiftSale exist?
I have no bloody idea.
All it seems to do is make everything far more complicated than it needs to be.
Anyway. My total commit?
Six lines.
IN FOUR FUCKING DAYS!
AHSKJGHALSKHGLKAHDSGJKASGH.7 -
The nightmare continues.
Currently dealing with a code review from a “principal” dev (one step above senior), who is unironically called a “legendary dev” by some coworkers. It’s painfully obvious he didn’t read the code, and just started complaining and nitpicking.
It’s full of requests to do things that make absolutely no sense, and would make the code an unmaintainable mess.
• Ex: moving the logic and data collection from the module’s many callers into the module instead of just passing in the data.
• Ex: hiding api endpoint declarations by placing them in the module itself, and using magic instance variables to pass data to it. Basically: using global functions and variables instead of explicit declarations and calls.
• Ex: moving the logic to determine which api endpoint to use, for all callers, into the view.
More comments about methods being “too complex” (barely holds water) right next to comments saying “why are these separate? merge them together!”
Incredulously asking how many times I’m checking permissions and how ridiculous it all is. (The answer? Twice.)
Conflating my “permissions” param and method names with a supposedly forthcoming permissions system overhaul, and saying I shouldn’t use permissions because my code will all have to get rewritten. Even if that were true, and it’s likely not, the ticket still needs to use the current permissions. I can’t just ignore them because they might be rewritten someday.
Requests to revert some code cleanup because the reviewer thought the previous heavily-nested and uncommented versions (with code duplication) were easier to read. Unsurprisingly, he wrote them.
On the same ticket, my boss wants me to remove all styling and clientside validation, debouncing, and error messages from a form. Says “success” and “connection failed” messages are good enough. The form in question sends SMS and email using arbitrary user input for addresses. He also says it shouldn’t be denounced on the server, and doesn’t want me to bother checking permissions. Hello, spam!
Related: the legendary dev reviewer says he can’t think of a reason why we would want to disable the feature for consumers, so I should remove the consumer feature flag.
You can’t make this stuff up.7 -
Legacy code.
Honestly though, this is some of the better legacy code I've worked with at this company. It's a nifty alert system wherein you can trigger sending messages to subscribers of that alert via whatever means (phone/email) they've entered.
I'll save you the technical analysis of its internals, but suffice to say it's actually pretty nice, with good separation of concerns, internal logic hidden away, dead-simple public interface, etc. documentation is kinda crap, but it exists (!), so that's a nice change.
but.
For some unknown and bloody bizarre reason, the thing breaks when a user wants both sms AND email notifications. Either by themselves work totally fine, but both together? nonono. Email alerts give ArgumentErrors, so something internal isn't correct, and SMS alerts complain about uninitialized Twilio::Error constants.
but.
they both work fine otherwise?
also, the two notification preferences aren't stored on the same object anywhere. if a user wants both, the user creates two AlertContact objects with different info, and when performed, the Alert basically iterates over these and does its thing for each, so there is no knowledge shared between them. totally should work the same regardless.
idfgi.
ALSO.
AND THIS PART REALLY PISSES ME OFF.
WHEN THERE'S AN ERROR, THIS THING DOESN'T LOG IT. IT STRINGIFIES THE ERROR OBJECT (basically just extracting the message) AND INSERTS THAT INTO THE DATABASE INSTEAD. WHAT THE CRAP.
So, I don't get a stack trace, line number, or anything. just the basic error message. instead of my alert text. because of course that makes sense and totally helps debugging.

Manager: Here's the design for the next feature, we're ready to hand it over to the consultant
FullStackClown: Uh... okay... is it spec'd out with requirements?
Manager: Huh?
FullStackClown: Well, already look at this design and user flow, did you consider what happens when <insert edge case X here>, <insert edge case Y here>, or <insert edge case Z here>? How is the consultant going to know what to put in for business logic if you don't even know or define it yourself?
Manager: Huh?
FullStackClown: Sigh... yeah, I'm too busy right now to be a kindergarten teacher, come back in a few days once you understand how your own feature is supposed to work

Let me explain a tiny corner of some awful code I read earlier today, in layman’s terms.
It’s a method to see if the user is in a secure session — not to set up the session, just to see if it exists. The method ends with a question mark, so it’s basically a question. It should look up the info (without changing anything) and should always give a clear yes/no answer. Makes sense, right?
Let’s say the question is “am I in school right now?”
The code… well.
If there isn’t a student, the answer it gives is null, not yes or no. Null is a fancy word for no, pretty much, so that’s kinda fine, but it really should be a simple no.
It then checks to see if the school is open today. If it is open, it then checks to see if I made my lunch, if I took my backpack, and if I rode the bus — and makes these things happen if they didn’t. Forgot my backpack? Just ask “am I in school today?” And poof! There’s my backpack! … but only if the school is open.
It then, finally, checks to see if I’m actually in the school, and gives that answer.
It could just see if I’m in the school — I mean, I could be in school without a backpack, or walked there on the weekend, right? Ha! You and your silly logic have no place here.
So, by asking if the user is in a secure session, we change the answer: they weren’t before, but the act of asking makes it so. This isn’t profound or anything: I don’t work with Schrödinger. My coworkers are just idiots.
And no, the rest of the code isn’t any better…7 -
Oh man. Mine are the REASON why people dislike PHP.
Biggest Concern: Intranet application for 3 staff members that allows them to set the admin data for an application that our userbase utilizes. Everything was fucking horrible, 300+ php files of spaghetti that did not escape user input, did not handle proper redirects, bad algo big O shit and then some. My pain point? I was testing some functionality when upon clicking 3 random check boxes you would get an error message that reads something like this "hi <SENSITIVE USERNAME DATA> you are attempting to use <SERVER IP ADDRESS> using <PASSWORD> but something went wrong! Call <OLD DEVELOPER's PHONE NUMBER> to provide him this <ERROR CODE>"
I panicked, closed that shit and rewrote it in an afternoon, that fucking retard had a tendency to use over 400 files of php for the simplest of fucking things.
Another one, that still baffles me and the other dev (an employee that has been there since the dawn of time) we have this massive application that we just can't rewrite due to time constraints. there is one file with (shit you not) a php include function that when you reach the file it is including it is just......a php closing tag. Removing it breaks down the application. This one is over 6000 files (I know) and we cannot understand what in the love of Lerdorf and baby Torvalds is happening.
From a previous job we had this massive in-house Javascript "framework" for ajax shit that for whatever reason unknown to me had a bunch of function and object names prefixed with "hotDog<rest of the function name>", this was used by two applications. One still in classic ASP and the other in php version 4.something
Legacy apps written in Apache Velocity, which in itself is not that bad, but I, even as a PHP developer, do not EVER mix views with logic. I like my shit separated AF thank you very much.
A large mobile application that interfaced with fucking everything via webviews. Shit was absolutley fucking disgusting, and I felt we were cheating our users.
A rails app with 1000 controller methods.
An express app with 1000 router methods with callbacks instead of async await even though async await was already a thing.
ultraFuckingLarge Delphi project with really no consideration for best practices. I, to this day enjoy Object Pascal, but the way in which people do delphi can scare me.
ASP.NET Application in wich there seemed to be a large portion of bolted in self made ioc framework from the lead dev, absolute shitfest, homie refused to use an actual ioc framework for it, they did pay the price after I left.

I once had to make a shitty canvas game as part of a marketing campaign when I worked for an agency, for fuck only knows what. You dragged a shopping trolley back and forth in an aisle, and got points for catching items that fell from the top.
The initial round of feedback had the complaint that sometimes players weren't receiving points for items. I spent a night playing this senseless game over and over, but I never failed to get the points for an item. I was pretty confident that it worked, it wasn't like the logic was complex, so I sent it over.
Second round of feedback had the same complaint. They were getting quite annoyed by it, said that it was a bad user experience. Again, I could not reproduce it at all: the game was an equally tedious waste of life on every device I tried it on.
In exasperation, I asked the sales guy whose pitch it had been to get me a video or a more detailed report. The client was quite arsey, as they saw it, at having to do bug-fixing for us, but they did agree.
Anyway, it transpired that they were angry that players were not receiving the points for the items they *failed* to catch. The way they saw it, the game wouldn't be fun if you were punished for not catching items - so they wanted the player to get ten points for every item on screen, regardless or not of whether they caught it in their trolley. Of course, I thought. Silly me.
I was actually quite impressed at how a marketing department could accidentally undermine the very notion of a game whilst seeking to make one more fun.8 -
Well... I had in over 15 years of programming a lot of PHP / HTML projects where I asked myself: What psychopath could have written this?
(PHP haters: Just go trolling somewhere else...)
In my current project I've "inherited" a project which was running around ~ 15 years. Code Base looked solid to me... (Article system for ERP, huge company / branches system, lot of other modules for internal use... All in all: Not small.)
The original goal was to port to PHP 7 and to give it a fresh layout. Seemed doable...
The first days passed by - porting to an asset system, cleaning up the base system (login / logout / session & cookies... you know the drill).
And that was where it all went haywire.
I really have no clue how someone could have been so ignorant to not even think twice before setting cookies or doing other "header related" stuff without at least checking the result codes...
Basically the authentication / permission system was fully fucked up. It relied on redirecting the user via header modification to the login page with an error set in a GET variable...
Uh boy. That ain't funny.
Ported to session flash messages, checked if headers were sent, hard exit otherwise - redirect.
But then I got to the first layers of the whole "OOP class" related shit...
It's basically "whack a mole".
Whoever wrote this, was as dumb and as ignorant to build up a daisy chain of commands for fixing corner cases of corner cases of the regular command... If you don't understand what I mean, take the following example:
Permissions are based on group (accumulation of single permissions) and single permissions - to get all permissions from a user, you need to fetch both and build a unique array.
Well... The "names" for permissions are not unique. I'd never expected to be someone to be so stupid. Yes. You could have two permissions name "article_search" - while relying on uniqueness.
All in all all permissions are fetched once for lifetime of script and stored to a cache...
To fix this corner case… There is another function that fetches the results from the cache and returns simply "one" of the rights (getting permission array).
In case you need to get the ID of the other (yes... two identifiers used in the project for permissions - name and ID (auto increment key))...
Let's write another function on top of the function on top of the function.
My brain is seriously in deep fried mode.
Untangling this mess is basically like getting pumped up with pain killers and trying to solve logic riddles - it just doesn't work....
So... From redesigning and porting from PHP 7 I'm basically rewriting the whole base system to MVC, porting and touching every script, untangling this dumb shit of "functions" / "OOP" [or whatever you call this garbage] and then hoping everything works...
A huge thanks to AURA. http://auraphp.com/
It's incredibily useful in this case, as it has no dependencies and makes it very easy to get a solid ground without writing a whole framework by myself.
Amen.2 -
For several years now, I have been writing programs for myself. I have been publishing the source code for them, but none of them ever got much traction. Then I wrote a program that existing users on social media could just interact with without installation (because even that is too much apparently).
When I wrote the programs for myself with others secondary, I had logic problems to solve and dealt with fucked up API's. Now I still have that problem, but I also have to deal with user retardation. They are not using the program in the way I wrote it to be used, at all. They are not passing arguments where there should be, they are running commands that are still under development and therefore (rightfully IMO) available to only me. I am the one being blamed, why doesn't this thing work?
I'd like to rephrase their question to me. Why are you user not using the goddamn program properly? Why should I need to make half the goddamn code account for users' sheer level of retardation?
Yes, users are retarded. And it's not a battle we can win. Earlier I heard this saying that "every time you make your tools more foolproof, the universe invents a better fool".7 -
Create an web application(a product of our company). Manager insisted on using X third party API instead of Y third party API.
Now the app is complete.
*Very slow, Shitty User Experience *
I feel shameful for creating such a disaster and also wasted 3 sprints on it. But couldn't do anything because I don't have an authority to take decision which API or technology stack I should use.
Business head and manager had a meeting. Now they want to use Y third party API.
So they called me for discussion, lets me know we will now use Y third party API and it should be completed within a week because we just need to change the API calls in code that's all, despite of knowing all the core logic is built around those API.
Don't know how to react to this :( Want to hit my head on a wall3 -
So I started in a new job a week ago for a two weeks probation period, im getting payed double than my last job but it's so professionally frustrating.
They use a full php stack with a framework called tinymvc that I never heard of and the last commit is from 2009.
Beside this they implement some sort of "flexible" MVC where a great amount of the logic are inside the views. They have one model for each entity (in theory) but in reality one model have methods for a lot of tables.
Beside this the i18n is done by querying the database for all the translation strings and copying it in every user session, so every session file it's about 400kb where around 380 are duplicated translations.
The views folder is empty because they decided to modify the framework to look for the views in another folder called resource's and the development must be done connected directly to the production database
Above all this shit all the many-to-many relations in the database (MySQL) are handled creating a comma separated field on one of the tables, completely breaking the reference integrity.
So, after a week of work I can't stop thinking who the fuck developed this? In which world this shit is okay? How can I work around this big lake of shit?7 -
Python is such an amazing programming language. Look how easy it is to write business-logic for the production world. This snippet is used at YouTube HQ to process how the users think about the ads that are displayed every now and then, while the user is listening to music1

As a pretty solid Angular dev getting thrown a react project over the fence by his PM I can say:
FUCK REACT!
It is nigh impossible to write well structured, readable, well modularized code with it and not twist your mind in recursion from "lift state up" and "rendercycle downwards only"
Try writing a modular modal as a modern function component with interchangeable children (passeable to the component as it should be) that uses portals and returns the result of the passed children components.
Closest I found to it is:
c o d e s a n d b o x.io/s/7w6mq72l2q
(and its a fucking nightmare logic wise and readability wise)
And also I still wouldn't know right of the bat how to get the result from the passed child components with all the oneway binding CLUSTERFUCK.
And even if you manage to there is no chance to do it async as it should be.
You HAVE to write a lot of "HTML" tags in the DOM that practically should not be anywhere but in async functions.
In Angular this is a breeze and works like a charm.
Its not even much gray matter to it...
I can´t comprehend how companies decide to write real big web apps with it.
They must be a MESS to maintain.
For a small "four components that show a counter and fetch user images" - OK.
But fo a big webapp with a big team etc. etc.?
Asking stuff about it on Stackoverflow I got edited unsolicited as fuck and downvoted as fuck in an instant.
Nobody explained anything or even cared to look at my Stackblitz.
Unsolicited edit, downvote, closevote and of they go - no help provided whatsoever.
Its completely fine if you don't have time to help strangers - but then at least do not stomp on beginners like that.
I immediately regretted asking a toxic community like this something that I genuinely seem to not understand. Wasn't SO about helping people?
I deleted my post there and won't be coming back and doing something productive there anytime soon.
Out of respect for my clients budget I'm now doing it the ugly react way and forget about my software architecture standards but as soon as I can I will advise switching to Angular.
If you made it here: WOW
Thank you for giving me a vent to let off some steam :)13 -
I got a project to "refactor" some shitty site. It was written in nativ php. The guy who wrote this is a moron.
The site is so unsecure that my dog could broke into it while barking at cats.
It's sooo unreadable and illogical.
Every time i look at the code i get sadder and sadder. And now i understand why so many people hate php..
**Jump in time**
After i planned the new logic. My boss told me i can't do any of this. Because they only need a new user lever..
Now i just stare at this pile of horse sh*t and rant about it.4 -
So first of all I'm not a dev.
I'm a software tester and my test manager is a douche, but this is not it.
Today I went to the end user place along with him to teach them how to test properly and how to manage the software test cycle in JIRA.
I did a demo and showed the users the software the dev team developed and of course there were a lot of rants about it.
Users noted down a list of things to be changed and we kept going.
By the end of the demo, my test manager started discussing the fact that I told these guys to open Bugs without test objects on Jira.
I mean, we don't have a test cycle or test cased yet but these guys found issues already, what's the point?
So here's the funny part.
He then starts telling users (which ignore testing fundaments) to create a test cycle called 'meeting of today dd/mm/yyyy" and create tests below it which were named with the names of who created them.
All of that without a logic and ignoring the fact that these tests were not tests.
I was laughing my ass off while assisting this total mess and I almost lost control.
And this is my manager.
Luckily, tomorrow is Saturday.4 -
I bring you all another gem from my computer science course, this time from my OOP class.
The first assignment we made for this class was a simple CLI shop, where you would have basically three main classes:
- A Product class that you extend to create different types of products.
- A Cart class that manages a list of products (basically an ArrayList<Product>) and has some useful methods
- A CLI class to display a simple interface to the user and call methods on a Cart.
Basic OOP stuff, so far so good.
Then for our second assignment the teacher asked us to make Cart a generic class, where you would say Cart<Bagel> and you would only be able to put bagels in it. This makes absolutely no fucking sense, this is not a good use case for generic types since
1) you would never limit your customer's cart to one type of product at compile time.
2) in Cart, you have to cast the generic type to Product to extract any information from the product, like when getting product prices to calculate the total price, so might as well use a fucking ArrayList<Product>
I'm just saying what he's asking us to do has (to our fictional shop's business logic) absolutely no advantage over subtyping.
Also, why the fuck teach generic constraints when you can just tell your students "just cast T to Product", right?
Like fucking hell, couldn't you spend like 10min to come up with a decent assignment that actually teaches generic types the right way? ffs
And just so no one can say "but wut simple assignment would you give to teach students generic types?", here's a simple and much, much better alternative: implementing your own ArrayList. Done. Can't get much better than that, it's a legit use case and teaches you the basics.
Sorry man, you're a great person, you really are, but you suck as a teacher.3 -
Pulled into an 'emergency' meeting with a group of web designers deeply concerned a particular service wasn't going to meet all their requirements.
DevA: "For each page, Its going to be A LOT of work to retrieve all the data and store it's state. Every page load will require a round trip to the service."
DevB: "Yes, we aren't sure how the service should be changed to do what we need."
Mgr: "What is it not doing now? Doesn't the service already returns all the necessary data?"
DevA: "Well...um...its all the boolean fields. Some may be defaulted from the database or false because the user unchecked the box. We have to know which is which"
Me: "Why? Are you doing anything different in the UI? Checkbox will be true or false. What or who set that value is irrelevant"
DevC: "Well, it matters if the user didn't fill out all other other values."
Me: "How so?"
DevA: "Its matters because the values in the other fields. Its going to be A TON of work to figure out."
<mgr goes to the white board>
Mgr: "Lets map this out...what fields are you needing to trigger the state on?"
DevA: "Um...uh...the 'Approved' field...and um...'OK to Contact' field"
Mgr: "Just those two?"
DevA: "Yea..um...there are other fields, but whether or not to show the edit box depends on those two."
Me: "The service already returns data, you only have two fields to check? I don't see a need to change the service at all."
DevA: "Returning all that data, we are going have a serious scaling problem. We'll be hitting the service A LOT. All that javascript could cause performance problems too"
Me: "How much data are we talking about? Name, address, couple of booleans?"
DevA: "I have to serialize the data. All that logic is going to be reeeaaallly complicated. It might be better if the service returned only the data I need."
Me: "$64,000 question, how often is this feature going to be used on the web site? Maybe once? Few hundred a week?"
Mgr: "We have no idea. A lot of the data will be pre-populated and we're only sending out a few thousand invitations. More around the holidays...but honestly, not very many."
Me: "Changing that service only for this particular area of the web site isn't going to happen. Changing the UI is the only course of action."
DevA: "Oh frack I can't wait until this project is over."
DevA...how the funck do still have a job here? You wasted about half-hour of my time with your cry-baby crap. Where is my hammer...no...no..don't go there...ahhh...thanks devrant. Prison sentence diverted.2 -
management logic.
dev : calling api on every product scroll is a stupid idea. we shouldn't do it. what if user has 100s of products bought?
mgmt : it isn't a practical scenario. in prod, we checked the data and we rarely have customers with more than 20 products
dev : 😮🤷♂️
dev : this is a rare issue that only happens for very old devices from this specific manufacturer. even manufacturers have acknowledged this.
mgmt : we don't care. fix it, as per data this error has been logged for more than 12 times (from 1 user only)
dev : 😮😢2 -
Aaaah ! So fuckin done with this Server error !
I am checking if a cookie is set in Php and if it is, I am redirecting user to some page, basically its a 'remember me' logic. But this fucking error comes in everytime my page redirects.
I have a similar logic to check if user is currently logged in the current session,and if he opens a new window and types the url(index.php) he is automatically logged in (obviously,duh !) and redirected,bt it dosent crash at that time!
Help 😥15 -
Ok now I'm gonna tell you about my "Databases 2" exam. This is gonna be long.
I'd like to know if DB designers actually have this workflow. I'm gonna "challenge" the reader, but I'm not playing smartass. The mistakes I point out here are MY mistakes.
So, in my uni there's this course, "Databases 2" ("Databases 1" is relational algebra and theoretical stuff), which consist in one exercise: design a SQL database.
We get the description of a system. Almost a two pages pdf. Of course it could be anything. Here I'm going to pretend the project is a YouTube clone (it's one of the practice exercises).
We start designing a ER diagram that describes the system. It must be fucking accurate: e.g. if we describe a "view" as a relationship between the entities User and Video, it MUST have at least another attribute, e.g. the datetime, even if the description doesn't say it. The official reason?
"The ER relationship describes a set of couples. You can not have two elements equal, thus if you don't put any attribute, it means that any user could watch a video only once. So you must put at least something else."
Do you get my point? In this phase we're not even talking about a "database", this is an analysis phase.
Then we describe the type dictionary. So far so good, we just have to specify the type of any attribute.
And now... Constraints.
Oh my god the constraints. We have to describe every fucking constraint of our system. In FIRST ORDER LOGIC. Every entity is a set, and Entity(e) means that an element e belongs to the set Entity. "A user must leave a feedback after he saw a video" becomes like
For all u,v,dv,df,f ( User(u) and Video(v) and View(u, v, dv) and feedback(u, v, f) ) ---> dv < df
provided that dv and df are the datetimes of the view and the feedback creation (it is clear in the exercise, here seems kinda cryptic)
Of course only some of the constraints are explicitly described. This one, for example, was not in the text. If you fail to mention any "hidden" constraint, you lose a lot of points. Same thing if you not describe it correctly.
Now it's time for use cases.
You start with the usual stickman diagram. So far so good.
Then you have to describe their main functions.
In first order logic. Yes.
So, if you got the point, you may think that the following is correct to get "the average amount of feedback values on a single video" (1 to 5, like the old YT).
(let's say that feedback is a relationship with attribute between User and Video
getAv(Video v): int
Let be F = { va | feedback(v, u, va) } for any User u
Let av = (sum forall f in F) / | F |
return av
But nope, there's an error here. Can you spot it (I didn't)?
F is a set. Sets do not have duplicates! So, the F set will lose some feedback values! I can not define that as a simple set!
It has to be a set of couples, like (v, u), where v is the value and u the user; this way we can have duplicate feedback values in our set.
This concludes the analysis phase. Now, the design.
Well we just refactor everything we have done until now. Is-a relations become relationships, many-to-many relationships get an "association entity" between them, nothing new.
We write down on paper every SQL statement to build any table, entity or not. We write down every possible primary key or foreign key. The constraint that are not natively satisfied by SQL and/or foreign keys become triggers, and so on.
This exam is considered the true nightmare at our department. I just love it.
Now my question is, do actually DB designers follow this workflow? Or is this just a bloody hard training in Pai Mei style?6 -
So yeah XML is still not solved in year 2018. Or so did I realize the last days.
I use jackson to serialize generic data to JSON.
Now I also want to provide serialization to XML. Easy right? Jackson also provides XML serialization facitlity similar to JAXB.
Works out of the box (more or less). Wait what? *rubbing eyes*
<User>
<pk>234235</pk>
<groups typeCode="usergroup">
<pk>6356679041773291286</pk>
</groups>
<groups typeCode="usergroup">
<pk>1095682275514732543</pk>
</groups>
</User>
Why is my groups property (java.util.Set) rendered as two separate elements? Who the fuck every though this is the way to go?
So OK *reading the docs* there is a way to create a collection wrapper. That must be it, I thought ...
<User typeCode="user">
<pk>2540591810712846915</pk>
<groups>
<groups typeCode="usergroup">
<pk>6356679041773291286</pk>
</groups>
<groups typeCode="usergroup">
<pk>1095682275514732543</pk>
</groups>
</groups>
</User>
What the fuck is this now? This is still not right!!!
I know XML offers a lot of flexibility on how to represent your data. But this is just wrong ...
The only logical way to display that data is:
<User typeCode="user">
<pk>2540591810712846915</pk>
<groups>
<groupsEntry typeCode="usergroup">
<pk>6356679041773291286</pk>
</groupsEntry>
<groupsEntry typeCode="usergroup">
<pk>1095682275514732543</pk>
</groupsEntry>
</groups>
</User>
It would be better if the individual entries would be just called "group" but I guess implementing such a logic would be pretty hard (finding a singular of an arbitrary word?).
So yeah theres a way for that * implementing a custom collection serializer* ... wait is that really the way to go? I mean common, am I the only one who just whants this fucking shit just work as expected, with the least amount of suprise?
Why do I have to customize that ...
So ok it renders fine now ... *writes test for it+
FUCK FUCK FUCK. why can't jackson not deserialize it properly anymore? The two groups are just not being picked up anymore ...
SO WHY, WHY WHY are you guys over at jackson, JAXB and the like not able to implement that in the right manner. AND NOT THERE IS ONLY ONE RIGHT WAY TO DO IT!
*looks at an apple PLIST file* *scratches head* OK, gues I'll stick to the jackson defaults, at least it's not as broken as the fucking apple XML:
<plist version="1.0">
<dict>
<key>PayloadOrganization</key>
<string>Example Inc.</string>
<key>PayloadDisplayName</key>
<string>Profile Service</string>
<key>PayloadVersion</key>
<integer>1</integer>
</dict>
</plist
I really wonder who at apple has this briliant idea ...2 -
(long post is long)
This one is for the .net folks. After evaluating the technology top to bottom and even reimplementing several examples I commonly use for smoke testing new technology, I'm just going to call it:
Blazor is the next Silverlight.
It's just beyond the pale in terms of being architecturally flawed, and yet they're rushing it out as hard as possible to coincide with the .Net 5 rebranding silo extravaganza. We are officially entering round 3 of "sacrifice .Net on the altar of enterprise comfort." Get excited.
Since we've arrived here, I can only assume the Asp.net Ajax fiasco is far enough in the past that a new generation of devs doesn't recall its inherent catastrophic weaknesses. The architecture was this:
1. Create a component as a "WebUserControl"
2. Any time a bound DOM operation occurs from user interaction, send a payload back to the server
3. The server runs the code to process the event; it spits back more HTML
Some client-side js then dutifully updates the UI by unceremoniously stuffing the markup into an element's innerHTML property like so much sausage.
If you understand that, you've adequately understood how Blazor works. There's some optimization like signalR WebSockets for update streaming (the first and only time most blazor devs will ever use WebSockets, I even see developers claiming that they're "using SignalR, Idserver4, gRPC, etc." because the template seeds it for them. The hubris.), but that's the gist. The astute viewer will have noticed a few things here, including the disconnect between repaints, inability to blend update operations and transitions, and the potential for absolutely obliterative, connection-volatile, abusive transactional logic flying back and forth to the server. It's the bring out your dead approach to seeing how much of your IT budget is dedicated to paying for bandwidth and CPU time.
Blazor goes a step further in the server-side render scenario and sends every DOM event it binds to the server for processing. These include millisecond-scale events like scroll, which, at least according to GitHub issues, devs are quickly realizing requires debouncing, though they aren't quite sure how to accomplish that. Since this immediately becomes an issue with tickets saying things like, "scroll event crater server, Ugg need help! You said Blazorclub good. Ugg believe, Ugg wants reparations!" the team chooses a great answer to many problems for the wrong reasons:
gRPC
For those who aren't familiar, gRPC has a substantial amount of compression primarily courtesy of a rather excellent binary format developed by Google. Who needs the Quickie Mart, or indeed a sound markup delivery and view strategy when you can compress the shit out of the payload and ignore the problem. (Shhh, I hear you back there, no spoilers. What will happen when even that compression ceases to cut it, indeed). One might look at all this inductive-reasoning-as-development and ask themselves, "butwai?!" The reason is that the server-side story is just a way to buy time to flesh out the even more fundamentally broken browser-side story. To explain that, we need a little perspective.
The relationship between Microsoft and it's enterprise customers is your typical mutually abusive co-dependent relationship. Microsoft goes through phases of tacit disinterest, where it virtually ignores them. And rightly so, the enterprise customers tend to be weaksauce, mono-platform, mono-language types who come to work, collect a paycheck, and go home. They want to suckle on the teat of the vendor that enables them to get a plug and play experience for delivering their internal systems.
And that's fine. But it's also dull; it's the spouse that lets themselves go, it's the girlfriend in the distracted boyfriend meme. Those aren't the people who keep your platform relevant and competitive. For Microsoft, that crowd has always been the exploratory end of the developer community: alt.net, and more recently, the dotnet core community (StackOverflow 2020's most loved platform, for the haters). Alt.net seeded every competitive advantage the dotnet ecosystem has, and dotnet core capitalized on. Like DI? You're welcome. Are you enjoying MVC? Your gratitude is understood. Cool serializers, gRPC/protobuff, 1st class APIs, metadata-driven clients, code generation, micro ORMs, etc., etc., et al. Dear enterpriseur, you are fucking welcome.
Anyways, b2blazor. So, the front end (Blazor WebAssembly) story begins with the average enterprise FOMO. When enterprises get FOMO, they start to Karen/Kevin super hard, slinging around money, privilege, premiere support tickets, etc. until Microsoft, the distracted boyfriend, eventually turns back and says, "sorry babe, wut was that?" You know, shit like managers unironically looking at cloud reps and demanding to know if "you can handle our load!" Meanwhile, any actual engineer hides under the table facepalming and trying not to die from embarrassment.36 -
4 years ago I made a personal goal/plan to be a full stack developer. Meaning a good understanding of any development between os level code and web/front end user experience.
Over the years this term 'full stack' has been abused greatly and now basically means 'a javascript developer that generally knows what they are talking about'.
So now, devRant collective I ask you. What do you call a developer with good skills in:
- os level code (c, c++ and os apis)
- database level tech (advanced querying and db aglo/modeling)
- software architecture
- application level (workflow and business logic)
- transport level (protocol design and usage)
- front end tech (graphics programming and event driven paradigm)
- user experience14 -
Had a legit argument with a manager about the text in a drop down menu. I argued that it should actually state what the option was for because I care about the user experience... Management wanted to conceal several business logic steps behind an unrelated option in the same menu because of a literal interpretation of the process and the client's request.
Interfaces should tell the user what is going on...2 -
Ah, developers, the unsung heroes of caffeine-fueled coding marathons and keyboard clacking symphonies! These mystical beings have a way of turning coffee and pizza into lines of code that somehow make the world go 'round.
Have you ever seen a developer in their natural habitat? They huddle in dimly lit rooms, surrounded by monitors glowing like magic crystals. Their battle cries of "It works on my machine!" echo through the corridors, as they summon the mighty powers of Stack Overflow and Google to conquer bugs and errors.
And let's talk about the coffee addiction – it's like they believe caffeine is the elixir of code immortality. The way they guard their mugs, you'd think it's the Holy Grail. In fact, a developer without coffee is like a computer without RAM – it just doesn't function properly.
But don't let their nerdy exteriors fool you. Deep down, they're dreamers. They dream of a world where every line of code is bug-free and every user is happy. A world where the boss understands what "just one more line of code" really means.
Speaking of bosses, developers have a unique ability to turn simple requests into complex projects. "Can you make a small tweak?" the boss asks innocently. And the developer replies, "Sure, it's just a minor change," while mentally calculating the time it'll take and the potential for scope creep.
Let's not forget their passion for acronyms. TLA (Three-Letter Acronym) is their second language. API, CSS, HTML, PHP, SQL... it's like they're playing a never-ending game of Scrabble with abbreviations.
And documentation? Well, that's their arch-nemesis. It's as if writing clear instructions is harder than debugging quantum mechanics. "The code is self-explanatory," they claim, leaving everyone else scratching their heads.
In the end, developers are a quirky bunch, but we love them for it. Their quirks and peculiarities are what make them the creative, brilliant minds that power our digital world. So here's to developers, the masters of logic and the wizards of the virtual realm!13 -
Here’s how my Friday night is going:
def signin
if should_not_sign_user_in?(stuff)
return redirect_to :nope
end
# signin logic
end
The guard says I shouldn’t sign the user in. It logs the details of why. I read the logs; they’re all correct. It logs the return value, which is false, and the user gets signed in anyway.
Wat.
There’s a return and a redirect there!
This is only happening on the QA server, too, so something fishy is going on.5 -
We had 1 Android app to be developed for charity org for data collection for ground water level increase competition among villages.
Initial scope was very small & feasible. Around 10 forms with 3-4 fields in each to be developed in 2 months (1 for dev, 1 for testing). There was a prod version which had similar forms with no validations etc.
We had received prod source, which was total junk. No KT was given.
In existing source, spelling mistakes were there in the era of spell/grammar checking tools.
There were rural names of classes, variables in regional language in English letters & that regional language is somewhat known to some developers but even they don't know those rural names' meanings. This costed us at great length in visualizing data flow between entities. Even Google translate wasn't reliable for this language due to low Internet penetration in that language region.
OOP wasn't followed, so at 10 places exact same code exists. If error or bug needed to be fixed it had to be fixed at all those 10 places.
No foreign key relationships was there in database while actually there were logical relations among different entites.
No created, updated timestamps in records at app side to have audit trail.
Small part of that existing source was quite good with Fragments, MVP etc. while other part was ancient Activities with business logic.
We have to support Android 4.0 to 9.0 of many screen sizes & resolutions without any target devices issued to us by the client.
Then Corona lockdown happened & during that suddenly client side professionals became over efficient.
Client started adding requirements like very complex validation which has inter-entity dependencies. Then they started filing bugs from prod version on us.
Let's come to the developers' expertise,
2 developers with 8+ years of experience & they're not knowing how to resolve conflicts in git merge which were created by them only due to not following git best practice for coding like only appending new implementation in existing classes for easy auto merge etc.
They are thinking like handling click events is called development.
They don't want to think about OOP, well structured code. They don't want to re-use code mostly & when they copy paste, they think it's called re-use.
They wanted to follow old school Java development in memory scarce Android app life cycle in end user phone. They don't understand memory leaks, even though it's pin pointed by memory leak detection tools (Leak canary etc.).
Now 3.5 months are over, that competition was called off for this year due to Corona & development is still ongoing.
We are nowhere close to completion even for initial internal QA round.
On top of this, nothing is billable so it's like financial suicide.
Remember whatever said here is only 10% of what is faced.

PouchDB.
It promised full-blown CRDT functionality. So I decided to adopt it.
Disappointment number one: you have to use CouchDB, so your data model is under strict regulations now. Okay.
Disappointment number two: absolutely messed up hack required to restrict users from accessing other users’ data, otherwise you have to store all the user data in single collection. Not the most performant solution.
Disappointment number three: pagination is utter mess. Server-side timestamps are utter mess. ANY server-side logic is utter mess.
Just to set it to work, you need PouchDB itself, websocket adapter (otherwise only three simultaneous syncs), auth adapter (doesn’t work via sockets), which came out fucking large pile of bullshit at the frontend.
Disappointment number four, the final one: auth somehow works but it doesn’t set cookie. I don’t know how to get access.
GitHub user named Wohali, number one CouchDB specialist over there, doesn’t know that either.
It also doesn’t work at Incognito mode, doesn’t work at Firefox at all.
So, if you want to use PouchDB, bear that in mind:
1. CouchDB only
2. No server-side logic
3. Authorization is a mess
4. Error logs are mess too: “ERROR 83929629 broken pipe” means “out of disk space” in Erlang, the CouchDB language.
5. No hosting solutions. No backup solutions, no infrastructure around that at all. You are tied to bare metal VPS and Ansible.
6. Huge pile of bullshit at frontend. Doesn’t work at Incognito mode, doesn’t work at Firefox.8 -
I absolutely hate software to the point where I started converting from sysadmin to becoming more like a dev. That way I could just write my own implementations at will. Easier said than done, that's for sure. And it goes both ways.
I think that in order to be a good dev, you need these skills the most:
- Problem solving skills
- Creativity, you're making stuff
- Logical reasoning
- Connecting the dots
- Reading complex documentation
- Breaking down said documentation
- A strong desire to create order and patterns
- ...
If you don't have the above, you may still be able to become a dev.. but it would be harder for sure, and in some cases acceptance will be lower (seriously, learn to Google!)
One thing I don't think you need in development is mathematics. Sure there's a correlation between it and logic reasoning, but you're not solving big mathematical monsters here. At most you'd probably be dealing with arrays and loops (well.. program logic).
Also, written and spoken English! The language of the internet must be known. If it's not your first language, learn it. All the good (and crucial) documentation out there is in English after all.
One final thing would be security in my opinion, since you're releasing your application to the internet and may even run certain services, and deal with a lot of user data. Making those things secure takes some effort and knowledge on security, but it's so worth it. At the most basic level, it requires a certain mindset: "how would I break this thing I just made?"4 -
This literally happened in my current team, and I'm not even an experienced dev yet.
Incident happened like this :
Our team is working on a RCP based on eclipse plugins, which has a headless mode and a GUI mode. Now, in the GUI mode, my manager cum architect thought there are no need of user log files (long story) because the user can see the info on screen, whereas in the headless mode, she wanted me to print the logs onto the console and a log file as well.
Now it just so happened that our team had got a recent addition as a replacement to our lead developer (she left the company) who claimed she had 3 years of expertise and a masters degree, and she was assigned a task. The task was to format a custom file we were generating out of the product (basically dumping info in a file) in a human-readable format. Miss new-addition-masters-degree decided it would be a very good idea to redirect the standard java output stream to a file output stream ( which she used for generating the formatted file ) but somehow never realized that she needed to reset the output stream back to standard output.
Consequences were devastating. I wrote the logic for the logger ( yes, apparently any available logging mechanism won't do it, again, long story ) and had it printing to a file in tmp directory. The logs seemed to be working fine initially but after a few logs, specifically from the point where the formatter started working, all the logs got printed in the formatted file. And this file was supposed to be used by our clients to develop something on top of it. Naturally, I got the heat of it and then naturally, worried and nervous and curious and in a frenzied state of mind, I started debugging.
When I got to the actual fault, I seriously could not decide whether to cry or laugh or call up miss masters and scream at her. I decided to ask her about what the hell she had written and her answer was most of it was written by the developer she replaced, so she didn't know it would cause this much problem. Anyway, I fixed the leak after that and averted the catastrophe.
And that, fellow devs, is the story of how I solved a crisis in my first year at corporate.1 -
Was working on a system we planned on to deliver to a hospital
basically it was meant for controlling and monitoring pactions coming in and attendance time from the staff
Got it off the ground well and got to where the system was supposed to update room status
occupied/free then horror started
the db was not setting the room free after clearing a client off the list... room remained occupied and this kept on happening for 6 months and I was so focused on fixing the db models thinking thats where the problem was....
1 day after leaving the project for several months i just revisited the project randomly and started going through the whole code base trying to make sense of what was happening as there where no errors generated..
I had to verify the whole system logic... and that day i figured out what was happening...
upon adding a client to a room the system was also creating a duplicate room so when the function for setting the room free executes it would set the duplicate room free and not the actual room and the system would pick the room with occupied state causing the user not being able to assign new pactions to the room
Solving this brought so much relief coz it required so much work just to solve what seemed to be a minor issue5 -
Yet another day at my company, Im rewriting some old code for client (rewriting old, php 4 system for vindications managment) and you know the moment when you are focused and someone comes to you to absolutely ruin your focus. Fine, whatever. Oh, for fuck sake. Again dev is doing as support becouse one moron with second can't login into zimbra admin panel and add fucking mailbox. I show them exacly how they login, remind them they are admins too, slowly show them, so you click "manage" than you click that gear icon and than you click "new", fill in email address and password. As simple as 1-2-3. Okay, fuck it, time to go for a cig. I just finish up few lines and stand, grab my vape and start walking towards door. In door I find my buddy with 2 random people. He told me that they are interns and that I should show them some basics and stuff around that. Oh god, fuck my life. If anything, Im definitely very bad teacher, mainly becouse I often have problems with saying what I mean in the way that somebody actually understans and knows what I am trying to say. Whatever. Fuck it all. I grab two of our old laptops that nobody used in like a year or so, and first thing I quickly figure out, is that one day for some what the fuck reason I dont even dont bothered to remember I installed Arch on both while I dont usually use Arch. I just needed it for some specific reason. Whatever. So I guess I will need to upgrade fucking system. Our network isn't really great so that was like... hour or so. In the meantime I figured what they know about coding in general etc, and holly shit. One of them (there was boy and girl), girl, apparently never ever in her life even touched code. Well... fuck. Why am I wasting my time? Becouse there was some programme or some shit like that... Someone could tell me before so I could mentally prepare.. fuck it. whatever. So while laptops are doing their pacman thing, I sit with them and slowly start to explain based on my machine some really basic concepts. Second guy actually had some expirience, he knew how to make some really really basic logic and stuff, so he had another world of problems, becouse it was PHP and, as we all know, everyone hates PHP, and... yeah.. You can probably imagine his approach. Yes, you get user input in super global array. I really wanted to say "Now shut the fuck up and write that fucking $_POST".
hour or so passed, I was close to giving up to not let my anger rise (im not really good teacher... I mentioned it. I suck at teaching others) but luckly machines upgraded. He wanted to use visual studio code, she didnt care too much, so I installed phpstorm in trial mode. whatever. Since that's linux and they were not comfortable with that, I walked them through installing LAMP stack, and when finally it started to look like LAMP stack, I requested them to google how to install xdebug, becouse xdebug is very usefull and googling skill is your best weapon on that field. I go for cig, come back and what I see boiled me a little bit. The girl was stuck looking at github page randomly looking through xdebug source code and idk... hoping for miracle (she admited she thought there will be instructions somewhere) and the guy was in good place, xdebug has a place to paste your phpinfo() for custom instructions. But it didn't work for him, he claims that wizzard told him it cant help him.. hmm intresting, you are sure you pasted in phpinfo? yes, he is sure. Okay, show me.
Again mindblown how someone can have problems with reading.
so his phpinfo() looked like that:
```<?php
phpinfo();```
I highlighted on the page the words "output of phpinfo". He somehow didn't see it or something. He didnt know, he thought that he needs to put in phpinfo so he did. OMG.
Finally, I figured out I can workaround my intern problem, and I just briefly shown them php.net, how documentation looks, said to allways google in english, if he uses tutorial to read whole fucking thing, not just some parts of it, and left them with simple task, that took them whole day and at which they ultimately failed.
To make 3 buttons labeled "1" "2" "3" and if someone presses one of them, remember in session that they pressed it and disallow pressing other ones.
Never fucking again interns. Especially those who randomly without apparent reason almost literally just spawn in front of you and here, its your fucking problem now.
Fuck it, I have some time to get back to my stuff. Time is running so lets not waste it.
After around 15 minutes my one of my superiors comes in and asks me if I can go on meeting with him and other superior. My buddy goes with us, and next 3 hours I was basically explaining that you cannot do some things (ie. know XYZ happened without any source of information) in code, and I can't listen for callbacks from ABC becouse it wont send anyc cuz in their fucking brilliant idea ABC can't even know that this script would even exist, not to mention it wants callbacks.
Sometimes I hate my job.4 -
"Non-technical" users must have some magic skill that goes beyond my understanding. How can anyone work with no-code page builders? I tried Wix, Webflow, Gutenberg, Elementor, Divi, and Semplice. Each one sucks in their way, but they have one thing in common: their UI behaves even more erratically than Microsoft Word.
Is there a "non-technical personal computer user" class where people learn that logic? How did they manage to hide their secret understanding from developers? Or what did I miss?8 -
Been a mobile developer since April, liking the experience and the amount of projects that I've been a part of.
And one of the things that I've learned about this is that sometimes the client doesn't even know what he really wants. I mean for fucksakes, we implement everything, and new functionalities and there's always something that works on every other app (and is basically a standard) and he thinks is not suppose to be like that...
And another thing. Fuck Apple Store. At the company we've developed an app that practically shows information that only users should see (in our logic is sensitive information from our clients) and they DECLINED 4 FUCKING TIMES THE APP. Reason? Since the app's purpose "isn't correlated" with the basical information we show, the user can navigate through the app without going through login.
We basically added an "explore option" that shows basically nothing and they've accepted. FUCK APPLE FOR WAISTING OUR TIME AND THE CLIENTS TIME1 -
To create an abstraction simple enough to make complex business logic challenges solvable for non programmers.
The issue I see today is programmers solving problems they don't understand as well as the user. I think two ways might be taken:
- Programmers specialize in other fields and solve problems there
- Other professionals create their own software
Both will happen in the future (IMHO) and I want to help the second happening.
Note: Excel does this really well, but I think we can so quite better today.2 -
Machine learning?
Maybe just maybe you could ask the user what he wants?
Or is the ML logic something like.
if(last_alert.status == unread)
user = uninterested;
else
user = interested; -
I wonder what is going on in the minds of inexperienced developers. It must be very interesting.
I just read this bit of code
The task was to implement a certain schema into a database. They were given an ORM library, and several tutorials explaining what an ORM was and how it did it.
The result were these 3 models:
- A defaultUser with all of the defaults values for the User model. It wasn't even supposed to be instantiated, just accessed by `defaultUser.fields.username.default`
- another default table for another model.
- The "main" model, containing all other models in the form of JSON fields that would contain an array with other JSON objects that would represent the instances themselves.
I will say though, they made a home-brew ORM with (most of) all the logic a normal ORM has by parsing through the "main model", except, of course, common sense2 -
Who actually started the reign of mixed character passwords? because seriously it sucks to have an unnecessarily complex password! Like websites and apps requesting passwords to contain Upper/Lower case letter, numeric characters and symbols without considering the average user with low memory threshold (i.e; Me).
Let's push the complaint aside and return back to the actual reason a complex password is required.
Like we already know; Passwords are made complex so it can't be easily guessed by password crackers used by hackers and the primary reason behind adding symbols and numbers in a password is simply to create a stretch for possible outcome of guesses.
Now let's take a look into the logic behind a password cracker.
To hack a password,
1) The Password Cracker will usually lookup a dictionary of passwords (This point is very necessary for any possible outcome).
2) Attempts to login multiple times with list of passwords found (In most cases successful entries are found for passwords less than 8 chars).
3) If none was successful after the end of the dictionary, the cracker formulates each password on the dictionary to match popular standards of most website (i.e; First letter uppercase, a number at the end followed by a symbol. Thanks to those websites!)
4) If any password was successful, the cracker adds them to a new dictionary called a "pattern builder list" (This gives the cracker an upper edge on that specific platform because most websites forces a specific password pattern anyway)
In comparison:
>> Mygirlfriend98##
would be cracked faster compared to
>> iloveburberryihatepeanuts
Why?
Because the former is short and follows a popular pattern.
In reality, password crackers don't specifically care about Upper-Lowercase-Number-Symbol bullshit! They care more about the length of the password, the pattern of the password and formerly used entries (either from keyloggers or from previously hacked passwords).
So the need for requesting a humanly complex password is totally unnecessary because it's a bot that is being dealt with not another human.
My devrant password is a short story of *how I met first girlfriend* Goodluck to a password cracker!6 -
I have found that once you work for a company where you have to implement everything in its raw form using the raw language and raw logic, you really have to know what you're doing and knowing some basic/medium programming and having some algebra knowledge doesn't cut it (unlike some people think).
I've been at two sides of the coin: I worked for a company that had everything in place, a framework that handled all edge cases and what not and I just had to focus on user stories, but I also worked for a company where I had to do everything manually.
For example, at the latter company I had to know Discrete Mathematics; truth tables to their most convoluted and disgusting form, having to be able to apply this on a late Friday night with a headache and lack of food and sleep with the PM stressing out.
I've had to deal with NOT AND OR AND OR AND OR AND branches or whatever, where an OR behaves like an AND and if you want a value between an AND AND and an OR, you'd have to do a NOT OR.. to think about latches, all in my head, sigh, anyway, within limited time constraints, without even having time to write tests, having to make sure that everything checks out while the client is breathing down my neck. Yeah, not such fun times.
I'm happy for those of you who can just write some moderately difficult logic but you don't have to break your head over doing everything manually, as if you're in the coding stone age and nothing is taken care of.
Companies like these make me want to run away.3 -
I'm making an interface where I have a few columns, much like Trello. In each column there are cards. I want the user to be able to drag these cards an place them in any column, in any order they want. The problem is that at the same time they should be able to sort each column on date or whatever. Do you guys have any ideas on how to deal with the clash between custom sorting and auto sorting? Like what happens when you're in date sorting, and you change the order of the cards?
The implementation/programming is no problem. I just need help to figure out the interaction logic behind it.
Thanks... :)5 -
The most excited was probably when I had to write a Visual Basic program with a try/catch statement that took user input and would send a “You Done Messed Up!” Popup Error message in the catch. For some reason it was sending it anyways even after the input was correct. Took me an hour of debugging to find out it was my logic that was wrong. Finished the assignment 5 minutes before it was due. I celebrated as if I had just won the World Cup.
-
Why do certain users ++ various posts of the same user in quick succession? I don't see the logic in this.10
-
There have been a few :)
If say it's a videos utter project I initially though was good. Apart from loading a view the controllers didn't do anything - my initial thought was some magic was happening behind the scenes.
However, when I opened up the view things changed.
ALL the business logic happened in the view. Everything. Form processing, consuming an app, file uploads, validation, crud ... You name it, it happened in view. The developer created a raw MySQL connection and build his queries by concatenation g strings, the whole system was wide open to sql injection.
Even more annoying was the "source control" he invented. Every file had several copies. I.e. "User(working).php", "user_v3.php" and even "user(working_no_profile_fields_1.php". It wasn't even like there was any consistency in what file was actually used either. A complete mess. The system had around 69 screens too. No idea how the developer got that gig.2 -
Jason Bourne logic: type "run predictive algorithm" without any parameters into a terminal and it returns the locations of whatever you want. Either that function is the _best_ at predicting user input, or its variables are so hardcoded that we've just discovered the hardest material on earth2
-
I love the logic that underlies algorithm. But nowadays I fear that this is almost disappeared, now programming a software is 5% logic and 95% read system specificactions, documentation, implement third part solutions, think about who developed the system thought it had to be and rant because you don't understand it. I like to solve math problems using algorithms rather than deal with user interactivity, for example. Yes, all this is pointless, but sometimes I miss the exercises that I did at school or in "IT Olympiad"

How do you implement TDD in reality?
Say you have a system that is TDD ready, not too sure what that means exactly but you can go write and run any unit tests.
And for example, you need to generate a report that uses 2 database tables so:
1. Read/Query
2. Processor logic
3. Output to file
So 1 and 3 are fairly straightforward, they don't change much, just mock the inputs.
But what about #2. There's going to be a lot of functions doing calculations, grouping/merging the data. And from my experience the code gets refactored a lot. Changing requirements, optimization (first round is somewhat just make it work) so entire functions and classes maybe deleted. Even the input data may change. So with TDD wouldn't you end up writing a lot of throwaway code?
A lot of times I don't know exactly what I want or need other than I need a class that can do something like this... but then I might end up throwing the whole thing out and writing a new one one I get a clearer idea of what i or the user wants or needs.
Last week I was building a new REST API, the parameters and usage changed like 3 times. And even now the code is in feasibility/POC testing just to figure out what needs to be used. Do I need more, less parameters, what should they be. I've moved and rewritten a lot of code because "oh this way won't work, need to try this way instead"
All I start with is my boss telling me I need an API that lets users to ... (Very general requirements).10 -
I would enjoy a position where I would have to write tons of tiny scripts for solving different logic problems. Tweak data, visualise it, pass it through different mediums. I would feel the best in research, implementing and testing different ideas, and build solutions for later use. Right now I'm on the first line at the customer site where the upcoming problems have to be solved instantly, I have the constant feeling that the thing could be much more efficient but there is no time for change, test and implement differently, so I'm not really using my full capacity on anything. I'm kind of a user of the built stuff but I feel more a developer. At the other end I'm satisfied and this is the best job I ever had :)1

I've been helping a friend of mine with his postgraduate project the last 3 months.
It was a Java based program made in Processing. Though I am not a Java developer and I never used processing before, it wasn't that hard to write the logic of the program.
I noticed that sometimes Java made me use loops for almost everything.
Also I had to communicate between server and client via JSON but I had to write it manually as string due to the lack of keys in Java.
The main trial though was with the logic of the project. It was supposed to be made as a framework to be extended from custom user classes. I had to change the core classes I made many times because the user class had methods that should run while the parent class didn't have them declared. That could be my fault for not knowing how to write desktop application framework but you can't expect a framework to be extended in a compiled state, or so I think. Processing on the other hand doesn't seem to like the idea of an external java library. At least it didn't workout for me, it should be able to work normally.
In the end the project was never as completed as we wanted. It could rum a basic sim but we hadn't the time to test other possibilities. -
I made a reminder application, with different sounds for different hours, but it's super primitive, as I'd never figured out how to use android intents that we'll, and the logic was barebones. I'd like to polish it up so it's a little more user friendly and intuitive.

I am having an introspective moment as a junior dev.
I am working in my 3rd company now and have spent the avg amount of time i would spent in a company ( 1- 1.5 years)
I find myself in similar problems and trajectories:
1. The companies i worked for were startups of various scales : an edtech platform, an insurance company (branch of an mnc) and a b2b analytics company
2. These people hire developers based on domain knowledge and not innovative thinking , and expect them to build anything that the PMs deem as growth/engagement worthy ( For eg, i am bad at those memory time optimising programming/ ds/algo, but i can make any kind of android screen/component, so me and people like me get hired here)
3. These people hire new PMs based on expertise in revenue generation and again , not on the basis of innovative thinking, coz most of the time these folks make tickets to experiment with buttons and text colors to increase engagement/growth
4. The system goes into chaos mode soon since their are so many cross operating teams and the PMs running around trying to boss every dev , qa and designer to add their changes in the app.
5. meanwhile due to multiple different teams working on different aspects, their is no common data center with up to date info of all flows, products and features. the product soon becomes a Frankenstein monster.
6. Thus these companies require more and more devs and QAs which are cogs in the system then innovative thinkers . the cogs in the system will simply come, dimwittingly add whatever feature is needed and goto home.
7. the cogs in system which also start taking the pain of tracking the changes and learning about the product itself becomes "load bearing cogs" : i.e the devs with so much knowledge of the product that they can be helpful in every aspect of feature lifecycle .
8. such devs find themselves in no need for proving themselves , in no need for doing innovative work and are simply promoted based on their domain knowledge and impact.
My question is simply this : are we as a dev just destined to be load bearing cogs?
we are doing the work which ideally a manager should be doing, ie maintaining confluence docs with end to end technical as well as business logic info of every feature/flow.
So is that the only definition of a Software Engineer in a technical product?
then how come innovations happen in companies like meta Microsoft google open ai etc?
if i have to guess as a far observer, i would say their diversity in different fields helps them mix and match stuff and lead to innovative stuff.
For eg, the android os team in google has helped add many innovative things in google cloud product and vice versa.
same is with azure and windows . windows is now optomissed to run in cloud machines when at one point it was just a horrible memory hogging and slow pc OS
for small companies, 1 ideology/product/domain is their hero ideology/product/domain .
an insurance company tries to experiment with stuff related to insurances,health,vehicles,and the best innovations they come up with is "lets give user a discount in premium if they do 5000 steps a day for an year".
edtech would say "lets do live streaming for children apart from static videos"
but Android team at google said , "since ai team is doing so well, lets include ai in various system apps and support device level models" ~ a much larger innovation as 2 domains combined to make a product
The small companies are not aiming to be an innovative product, they are just aiming to be a monopoly product. and this is kinda sad2 -
I am currently weeks apart from releasing my pet project, which I am working on for almost 6 years now. Of course, there were a few stops here and there, but overall I've spent a lot of time and effort on this to make it work. It is far from complete but I am really happy with the results.
Now, since I am not a professional by any means - it is all a hobby for me - I was wondering, that how much my work would cost, if it were to made by professionals. Below the details so you can get a grasp of the thing.
The whole system is for our family business. We are selling parts for an old-timer truck model. The website was pretty much done already, people like it, it only needed some polishing and adding of the new features. But the thing behind it is monstrous (at least for me).
Apart from the custom-made CMS for the website (most of it was done already and didn't need to change), we can handle orders, partners, prices, stocks, overdue partners, pretty much anything a CRM would do.
There is a logic to automatically make orders based on import prices, or give the customer a custom discount based on the price gap of each product. There are products, which can contain other products, and their prices are dynamically changed based on a given formula, once an underlying product price changes. We can send e-mails when an order status changes, and there is also a page, where a user can interact whit their order, like changing the shipping or the delivery address. The system is (or will in the following weeks) also connected to multiple shipping companies' API, so we can order deliveries and print labels directly from our system. The whole thing is a custom made Laravel project by the way. There are countless more features, but I've just spent 2 hours explaining all to my father and was only be able to cover like half of it.
And why it is all custom made, you ask? Well, the business logic is a bit twisted, so it would be hard to operate as a regular web shop, since the availability of the products are uncertain, given the fact that it is a model, which isn't manufactured in 30 years. So, we can't just accept and send orders without confirming. It is also a thing, that people usually don't know what they need to order for their truck, so we have to help them, so they don't waste their money and the precious last pieces of a part unnecessarily.
Sorry for this rather long post, and it might feel like I just want to brag (well, I kinda do), but I am honestly interested in what such a custom product would cost in the market.
Thank you for your time answering.6 -
Rant and geniune question:
How can a group of 'devs' make 2 functional(enough unfortunately), many active users, phone apps, not just basic af, over a few years... but apparently not know how to make a working referral link of any kind???
Am i missing something like referral code link logic being extremely hard for typical devs to understand? Or some odd or trending reason for for forcing manual, explicit, referral code binding instead of a simple (imo) link that attributes the new user account to the referring user's? If you dont believe me u can check either/both of their actively running, decent/moderate size user base apps, claw eden (on play store) and/or claw party (possibly only via finding an apk... at least not on google play).
They have legit rewards, relatively very fair/honest policy... etc... i get 60+ items won/delivered a month (i have paranormal crane game skills #AutisticSuperpower) which i donate the vast majority of to charity (1 of 3 reasons the IRS reeeeally dislikes me).
Im just baffled by this apparent inability.2 -
I wanted to know what is the worst mistake you make on database.
I have actually implements the logic of token access control on database and not on business logic layer.
The database have a login procedure which accept username and password. That login procedure actually hash the password and try to authenticate user.
If it is a correct user , it generate a token. In other to use other procedure on database , you must provide a token. By using that token , the procedure know who is it and what permission is granted to that user.4 -
I've spent a day trying to figure out a code logic. Couldn't figure out why some codes that shouldn't be commented out are commented out.
Out of frustration, I went to see the user. She explained to me the logic behind it and I got it right away within 5 minutes.
Ask your user when in doubt and in trouble figuring out the logic. -
i am feeling angry and frustrated. not sure if it's a person ,or codebase or this bloody job. i have been into the company for 8 months and i feel like someone taking a lot of load while not getting enough team support to do it or any appreciation if i do it right.
i am not a senior by designation, but i do think my manager and my seniors have got their work easy when they see my work . like for eg, if on first release, they told me that i have to update unit tests and documentation, then on every subsequent release i did them by default and mentioning that with a small tick .
but they sure as hell don't make my work easy for me. their codebase is shitty and they don't give me KT, rather expect me to read everything on my own, understand on my own and then do everything on my own, then raise a pr , then merge that pr (once reviewed) , then create a release, then update the docs and finally publish the release and send the notification to the team
well fine, as a beginner dev, i think that's a good exercise, but if not in the coding step, their intervention would be needed in other steps like reviewing merging and releasing. but for those steps they again cause unnecessary delay. my senior is so shitty guy, he will just reply to any of my message after 2-3 hours
and his pr review process is also frustrating. he will keep me on call while reviewing each and every file of my pr and then suggest changes. that's good i guess, but why tf do you need to suggest something every fucking time? if i am doing such a shitty coding that you want me to redo some approach that i thought was correct , why don't you intervene beforehand? when i was messaging you for advice and when you ignored me for 3 hours? another eg : check my comment on root's rant https://devrant.com/rants/5845126/ (am talking about my tl there but he's also similar)
the tasks they give are also very frustrating. i am an android dev by profession, my previous company was a b2c edtech app that used kotlin, java11, a proper hierarchy and other latest Android advancements.
this company's main Android product is a java sdk that other android apps uses. the java code is verbose , repetitive and with a messed up architecture. for one api, the client is able to attach a listener to some service that is 4 layers down the hierarchy , while got other api, the client provides a listener which is kept as a weak reference while internal listeners come back with the values and update this weak reference . neither my team lead nor my seniors have been able to answer about logic for seperation among various files/classes/internal classes and unnecessary division of code makes me puke.
so by now you might have an idea of my situation: ugly codebase, unavailable/ignorant codeowners (my sr and TL) and tight deadlines.
but i haven't told you about the tasks, coz they get even more shittier
- in addition to adding features/ maintaining this horrible codebase , i would sometimes get task to fix queries by client . note that we have tons of customer representatives that would easily get those stupid queries resolced if they did their job correctly
- we also have hybrid and 3rd party sdks like react, flutter etc in total 7 hybrid sdks which uses this Android library as a dependency and have a wrapper written on its public facing apis in an equally horrible code style. that i have to maintain. i did not got much time/kt to learn these techs, but once my sr. half heartedly explained the code and now every thing about those awful sdls is my responsibility. thank god they don't give me the ios and web SDK too
- the worst is the shitty user side docs. I don't know what shit is going there, but we got like 4 people in the docs team and they are supposed to maintain the documentation of sdk, client side. however they have rasied 20 tickets about 20 pages for me to add more stuff there. like what are you guys supposed to do? we create the changelog, release notes , comments in pr , comments in codebase , test cases, test scenarios, fucking working sample apps and their code bases... then why tf are we supposed to do the documentation on an html based website too?? can't you just have a basic knowledge of running the sample, reading the docs and understand what is going around? do i need to be a master of english too in addition to being a frustrated coder?
just.... fml -
Software Message: "you didn't change data, you don't need to save."
Damn it, how about simply writing the same data?
Or is this just user logic?2 -
!rant
Got a question since I've been working with ancient web technologies for the most part.
How should you handle web request authorization in a React app + Rest API?
Should you create a custom service returning to react app what the user authenticated with a token has access to and create GUI based on that kind of single pre other components response?
Should you just create the react app with components handling the requests and render based on access granted/denied from specific requests?
Or something else altogether? The app will be huge since It's a rewrite off already existing service with 2500 entities and a lot of different access levels and object ownerships. Some pages could easily reach double digits requests if done with per object authorization so I'm not quite sure how to proceed and would prefer not to fuck it up from the get go and everyone on the team has little to no experience with seperated frontend/backend logic.4 -
At old e-commerce job, some orders were coming through with most of the shipping info missing. The only info filled out was the State. When we looked at Heap, we could see the user was filling in those fields. There was both frontend and backend validation for required form data, so the user shouldn’t have been able to checkout without an address.
When I looked at the BE logic, I saw addresses were retrieved from our database by using a method called GetOrCreateDefaultAddress. When the website couldn’t find the address in the db, it created a new one where the only address field that was filled in was the state.
Unfortunately, this default address creation was happening after the submit button had been hit. There was no logic to validate the address this late in the checkout because the earlier form validation in the process should have caught this.
The orders did have email addresses, so customer service did have a way to contact the customer. I have no idea what happened to the user’s address. Was it never saved? Did it get caught up in a cron job to delete old users and addresses from the db??2 -
You know how the machine learning systems are in the news (and Ted talks, tech blogs, etc.) lately over how they're becoming blackbox logic machines, creating feedback loops that amply things like racism on YouTube, for example. Well, what might the ML/AI systems be doing with our code repositories? Maybe not so much yet, I don't know. But let's imagine. Do you think it's probably less worrisome? At first I didn't see as much harm potential, there's not really racist code, terrorist code, or code that makes people violence prone (okay, not entirely true...), but if you imagine the possibility that someone might use code repositories to create applications that modify code, or is capable of making new programs, or just finding and squishing bugs in code algorithmically, well then you have a system that could arguably start to get a little out of control! What if in squashing code bugs it decides the most prevalent bugs are from code that takes user input (just one of potentially infinite examples). Remember though, it's a blackbox of sorts and this is just one of possibly millions of code patterns it's finding troublesome, and most importantly it's happening slowly (at first). Just like how these ML forces are changing Google and YouTube algorithms so slowly that many don't notice the changes; this would presumably be similar and so it may not be as obvious as one would think. So anyways, 'it' starts refactoring code that takes user input into something 'safer'. Great! But what does this mean? Not for this specific example really, but this concept of blackbox ML/AI solutions to problems we didn't realize we had, what does a future with this stuff look like (Matrix jokes aside)? Well, I could go on all day with imaginative ideas... But talking to myself isn't so productive, let's start a fun community discussion here! Join in if you find this topic as interesting as I do! :)
Note: if you decide to post something like "SNN have made this problem...", or other technical jargan please explain it as clearly as possible. As the great Richard Feynman once said, the best way to show you understand a thing is to be able to explain it clearly to others who don't understand it... Or something like that ;)3 -
Starting to wonder why I tend to like our QA people so much: they often seem so much saner. Yes, sometimes they quibble as with the complaints about a page that is hidden from the user anyway, but they would usually not creep to deep into the hole creating most unintuitive workflows and abysmal logic.
Disclaimer: We're more like backend devs, but we had to do a UI which was beautifully slaughtered by the CEO messing with it - guess what's happening with the new one - and because of that... thing I already nearly smashed my Mac because stupid entered credentials for updating software would only be applied if you defocused once out of the password entry box. Fucked up stuff like this, which devs meddle with, give up, just shrug it off and dump it on the (l)user.
Or a more recent example: So PM wanted a stupid "Apply to all" buttons on a list that can be filtered. Guess to which items the actions should be applied if you filtered it and you currently only see a small selection in your window! Yes, of course it still applies to all items in the universe. QA guy who's just trying the buttons comes to me: "Hey, you sure this "apply all"-stuff supposed to work like that?"
Third example to end this long QA-praise: So there is this virtual appliance we build and we should support another stupid hypervisor.. and he found the kernel modules I have to activate additionally so we can just convert the existing image without having to create a new build system.3 -
Need help
I recently applied for an internship and had the interview already so far it went great but they did request some code to see my logic in development.
Currently I'm working on a permission based user account system in php so that a single system can be used for both mods and regular users and should be quite easy to implement into a site build from scratch.
What I wonder is if it'll be interesting enough to show to them.
The company develops wesites, apps and educational games.
I'd love to hear your thoughts.3 -
HOW to document business logic in code?
background:
I'm a frontend dev for admin system of our company. Often times I code things like: if user choose this product type and that settings then I show some other input field to input. I deal with mostly forms and show/hide UI for user. And after some time nor did user/PM/test or myself remember the logic of what should show or why something do not show.
So I want something to be able to let me write code and business logic along the way.(I'm not asking for API docs or function docs like JSDoc)
Great Thanks
Related topics:
And In terms of this, I would also like to build something to centralize PM's business DOC with developers API/dev Doc and also things like how to test for our test team and etc... basically a unified place to document everything, I think scenarios like these inside companies should exists so I would like to know how other company do this.9 -
Yesterday, I told CS that it looks like a member created the account that the member claim they didn’t create. Member probably forgot or didn’t realize what they were doing.
CS asks me if I’m sure because this member is one of their higher tier members. Lol no matter what your membership level, user error happens. Because they can afford to drop $10k on a membership doesn’t make them infallible. But rich people are something else and don’t care about logic. So I understand why CS is hesitant to tell a rich person that the mistake wasn’t on our end.
Definitely wasn’t our mistake or a hacker. This specific user account’s creation has details that indicate user creation rather than someone else making it.
I feel bad that CS has to deal with the communication, but I’m also glad I escaped that life.1 -
i always get sucked into this "cute code" hell whenever i am working with a b2c codebase, and especially with kotlin code.
here's a scenario:
task : build a debounce logic for an input view where each user input is currently triggerring an api call.
my steps
1. read what debouncing is.
2. see if any code is available on the internet
=> found a code piece on the internet with some level of abstraction ( basically a simple final class that implements the input event callback and encapsulates the debounce logic)
3) copy it, run it , it wokrs
------
for any sane coder, these steps are hardly 10-30 mins and they can move on with life. but its your truly that made this task into a 6hour research only to come up at similar solution. my curiosity led me to stupid places
1) why this class is final? what if someone else wanna use it but with a different behaviour? lets try open(non final class) .
2) why even use a class? it extends an interface, lets try to wrap the logic in interface itself (kotlin supports interfaces that don't require implementation)
3) umm , the interface works but it looks ugly, with all its global overridden variables. what about we make it extension?
4) yeah the extension approach is also not very good, lets go back to open class.
5) but extend is super nice to look! lets keep the extension and open class too
6) can we optimise the implementation? why it uses an additional handler? what if we provided everything in constructor? how about builder pattern?
FUCK MY BRAIN! there are so much fucking options that i forgot that i spent 4 hours on this small thing
the simplest approach would have been tk just shove all the listeners and everything in activity and forget about it :/
senior devs on this platform, how do you stop yourself from adding every concept that you know into the smallest possible task?6 -
Ok, so for past 1 whole day I am trying to make vhost work on my brand new laptop, running Ubuntu 16.04 LTS... When I installed OS, I've set hard disk encryption, and on top of it - user home folder encryption. Don't ask me why I did both.
Setting up vhost is simple and straight forward - I did it hundreds, maybe thousands of times, on various Linux distros, server and desktop releases alike.
And of course, as it usually happens, opposed to all logic and reason - setting up virtual host on this machine did't work. No matter what I do - I get 403 (access not allowed).
All is correctly set - directory params in apache config, vhost paths, directory params within vhost, all the usual stuff.
I thought I was going crazy. I go back to several live servers I'm maintaining - exactly the same setup that doesn't work on my machine. Google it, SO-it, all I can see is exactly what I have been doing... I ended up checking char by char every single line, in disbelief that I cannot find what is the problem.
And then - I finally figured it out after loosing one whole day of my life on it:
I was trying to setup vhost to point to a folder inside my user's home folder - which is set to be encrypted.
Aaaaaand of course - even with all right permissions - Apache cannot read anything from it.
As soon as I tried any other folder outside my home folder - it worked.
I cannot believe that nobody encountered this issue before on Stackoverflow or wherever else.9 -
Ruby and its "simplicity" hurts me... Tried to make a if-statement checking if user is signed in... Well logic would say it's "if (user != signed_in)" right? Well logic don't apply in Ruby, in this realm you do "if (user_signed_in?)". As a logic programmer this bugs me...
Anyone relating?4 -

Function in my Dao file is:
@Query("SELECT * from appData WHERE type = :type ORDER BY id DESC")
fun getData(type: String): Flow<List<AppData>>
The database contains a column of automatically generated int primary key 'id', a column of string named 'type', and another string column named 'content'.
A Part of code from my composable function is:
val currentRetrievedDate: Date = Date()
val currentDate: String = SimpleDateFormat("dd-MM-yyyy").format(currentRetrievedDate)
var lastDateObjectList by remember { mutableStateOf(emptyList<AppData>()) }
LaunchedEffect(streakCounterViewModel) {
coroutineScope {
streakCounterViewModel.appDataRepository.getDataStream("lastDate")
.collect { newDataList ->
lastDateObjectList = newDataList as List<AppData>
}
}
}
if (lastDateObjectList.size>1){/*TODO*/
for (i in 1 until lastDateObjectList.size){
LaunchedEffect (Unit){
streakCounterViewModel.deleteData(id = lastDateObjectList[i]!!.id,
type = lastDateObjectList[i]!!.type,
content = lastDateObjectList[i]!!.content)
}
}
}
val lastDateObject: AppData?/* = lastDateObjectList[0] ?: null*/
lastDateObject = if (lastDateObjectList.isNotEmpty())
lastDateObjectList[0]
else null
var lastDate = lastDateObject?.content ?: "00-00-0000"
var currentStreakObjectList by remember { mutableStateOf(emptyList<AppData>()) }
LaunchedEffect(streakCounterViewModel) {
coroutineScope {
streakCounterViewModel.appDataRepository.getDataStream("currentStreak")
.collect { newDataList ->
currentStreakObjectList = newDataList as List<AppData>
}
}
}
if (currentStreakObjectList.size>1){
for (i in 1 until currentStreakObjectList.size){
LaunchedEffect (Unit){
streakCounterViewModel.deleteData(id = currentStreakObjectList[i]!!.id,
type = currentStreakObjectList[i]!!.type,
content = currentStreakObjectList[i]!!.content)
}
}
}
val currentStreakObject: AppData?/* = currentStreakObjectList[0] ?: null*/
currentStreakObject = if (currentStreakObjectList.isNotEmpty())
currentStreakObjectList[0]
else null
var currentStreak = currentStreakObject?.content ?: "0"
In this code, the last login time and last streak of user is already saved, we just have to fetch the data from the local database, make sure that there are not more than 1 occurrences of same data type in the database, and then use that data. But this, instead of using the database values, uses 00-00-0000 as the lastDate, and uses "0" as the currentStreak (which should only be used for the first not, and in some rare situations only), and is not able to retrieve data from the database properly.
The data saving and updating logic is working fine, but only the retrieval part is causing some issue.

#Suphle Rant 6: Deptrac, phparkitect
This entry isn't necessarily a rant but a tale of victory. I'm no more as sad as I used to be. I don't work as hard as I used to, so lesser challenges to frustrate my life. On top of that, I'm not bitter about the pace of progress. I'm at a state of contentment regarding Suphle's release
An opportunity to gain publicity presented itself last month when cfp for a php event was announced last month. I submitted and reviewed a post introducing suphle to the community. In the post, I assured readers that I won't be changing anything soon ie the apis are cast in stone. Then php 7.4 officially "went out of circulation". It hit me that even though the code supports php 8 on paper, it's kind of a red herring that decorators don't use php 8 attributes. So I doubled down, suspending documentation.
The container won't support union and intersection types cuz I dislike the ambiguity. Enums can't be hydrated. So I refactored implementation and usages of decorators from interfaces to native attributes. Tried automating typing for all class properties but psalm is using docblocks instead of native typing. So I disabled it and am doing it by hand whenever something takes me to an unfixed class (difficulty: 1). But the good news is, we are php 8 compliant as anybody can ask for!
I decided to ride that wave and implement other things that have been bothering me:
1) 2 commands for automating project setup for collaborators and user facing developers (CHECK)
2) transferring some operations from runtime to compile/build TIME (CHECK)
3) re-attempt implementing container scopes
I tried automating Deptrac usage ie adding the newly created module to the list of regulated architectural layers but their config is in yaml, so I moved to phparkitect which uses php to set the rules. I still can't find a library for programmatically updating php filed/classes but this is more dynamic for me than yaml. I set out to implement their library, turns out the entire logic is dumped into the command class, so I can neither control it without the cli or automate tests to it. I take the command apart, connect it to suphle and run. Guess what, it detects class parents as violations to the rule. Wtflyingfuck?!
As if that's not bad enough, roadrunner (that old biatch!) server setup doesn't fail if an initialization script fails. If initialization script is moved to the application code itself, server setup crumbles and takes the your initialization stuff down with it. I ping the maintainer, rustacian (god bless his soul), who informs me point blank that what I'm trying to do is not possible. Fuck it. I have to write a wrapper command for sequentially starting the server (or not starting if initialization operations don't all succeed).
Legitimate case to reinvent the wheel. I restored my deleted decorators that did dependency sanitation for me at runtime. The remaining piece of the puzzle was a recursive film iterator to feed the decorators. I checked my file system reader for clues on how to implement one and boom! The one I'd written for two other features was compatible. All I had to do was refactor decorators into dependency rules, give them fancy interfaces for customising and filtering what classes each rule should actually evaluate. In a night's work (if you're discrediting how long writing the original sanitization decorators and directory iterator), I coupled the Deptrac/phparkitect library of my dreams. This is one of the those few times I feel like a supreme deity
Hope I can eat better and get some sleep. This meme is me after getting bounced by those three library rejections
