Yesterday: Senior dev messages out a screenshot of someone using an extension method I wrote (he didn’t know I wrote it)..

SeniorDev: “OMG…that has to be the stupidest thing I ever saw.”
Me: “Stupid? Why?”
SeniorDev: “Why are they having to check the value from the database to see if it’s DBNull and if it is, return null. The database value is already null. So stupid.”
Me: “DBNull is not null, it has a value. When you call the .ToString, it returns an empty string.”
SeniorDev: ”No it doesn’t, it returns null.”
<oh no he didn’t….the smack down begins>
Me: “Really? Are you sure?”
SeniorDev: “Yes! And if the developer bothered to write any unit tests, he would have known.”
Me: “Unit tests? Why do you assume there aren’t any unit tests? Did you look?”
<at this moment, couple other devs take off their head phones and turn around>
SeniorDev:”Well…uh…I just assumed there aren’t because this is an obvious use case. If there was a test, it would have failed.”
Me: “Well, let’s take a look..”
<open up the test project…navigate to the specific use case>
Me: “Yep, there it is. DBNull.Value.ToString does not return a Null value.”
SeniorDev: “Huh? Must be a new feature of C#. Anyway, if the developers wrote their code correctly, they wouldn’t have to use those extension methods. It’s a mess.”
<trying really hard not drop the F-Bomb or two>
Me: “Couple of years ago the DBAs changed the data access standard so any nullable values would always default to null. So no empty strings, zeros, negative values to indicate a non-value. Downside was now the developers couldn’t assume the value returned the expected data type. What they ended up writing was a lot of code to check the value if it was DBNull. Lots of variations of ‘if …’ , ternary operators, some creative lamda expressions, which led to unexpected behavior in the user interface. Developers blamed the DBAs, DBAs blamed the developers. Remember, Tom and DBA-Sam almost got into a fist fight over it.”
SeniorDev: “Oh…yea…but that’s a management problem, not a programming problem.”
Me: “Probably, but since the developers starting using the extension methods, bug tickets related to mis-matched data has nearly disappeared. When was the last time you saw DBA-Sam complain about the developers?”
SeniorDev: “I guess not for a while, but it’s still no excuse.”
Me: “Excuse? Excuse for what?”
<couple of awkward seconds of silence>
SeniorDev: “Hey, did you guys see the video of the guy punching the kangaroo? It’s hilarious…here, check this out.. ”

Pin shoulders the mat…1 2 3….I win.

Yesterday, in a meeting with project stakeholders and a dev was demoing his software when an un-handled exception occurred, causing the app to crash.

Dev: “Oh..that’s weird. Doesn’t do that on my machine. Better look at the log”
- Dev looks at the log and sees the exception was a divide by zero error.
Dev: “Ohhh…yea…the average price calculation, it’s a bug in the database.”
<I burst out laughing>
Me: “That’s funny.”
<Dev manager was not laughing>
DevMgr: “What’s funny about bugs in the database?”
Me: “Divide by zero exceptions are not an indication of a data error, it’s a bug in the code.”
Dev: “Uhh…how so? The price factor is zero, which comes from a table, so that’s a bug in the database”
Me: “Jim, will you have sales with a price factor of zero?”
StakeholderJim: “Yea, for add-on items that we’re not putting on sale. Hats, gloves, things like that.”
Dev: “Steve, did anyone tell you the factor could be zero?”
DBA-Steve: “Uh...no…just that the value couldn’t be null. You guys can put whatever you want.”
DevMgr: “So, how will you fix this bug?”
DBA-Steve: “Bug? …oh…um…I guess I could default the value to 1.”
Dev: “What if the user types in a zero? Can you switch it to a 1?”
Me: “Or you check the factor value before you try to divide. That will fix the exception and Steve won’t have to do anything.”
<awkward couple of seconds of silence>
DevMgr: “Lets wrap this up. Steve, go ahead and make the necessary database changes to make sure the factor is never zero.”
StakeholderJim: “That doesn’t sound right. Add-on items should never have a factor. A value of 1 could screw up the average.”
Dev: “Don’t worry, we’ll know the difference.”
<everyone seems happy and leaves the meeting>

I completely lost any sort of brain power to say anything after Dev said that. All the little voices kept saying were ‘WTF? WTF just happened? No really…W T F just happened!?’ over and over. I still have no idea on how to articulate to anyone with any sort of sense about what happened. Thanks DevRant for letting me rant.

Logic Gem found at work today.

if (value != null) {
return value;
} else {
return null;
}

😂 😂😂😂😂😂

The worst Code I saw was

if (value != null ) {
return value;
} else {
return null;
}

I was suppose to review this code.

if (null != value) {
return value;
} else {
return null;
}

null vs undefined

Imagine, you get employed to restart a software project. They tell you, but first we should get this old software running. It's 'almost finished'.
A WPF application running on a soc ... with a 10" touchscreen on win10, a embedded solution, to control a machine, which has been already sold to customers. You think, 'ok, WTF, why is this happening'?
You open the old software - it crashes immediately.
You open it again but now you are so clever to copy an xml file manually to the root folder and see all of it's beauty for the first time (after waiting for the freezed GUI to become responsive):
* a static logo of the company, taking about 1/5 of the screen horizontally
* circle buttons
* and a navigation interface made in the early 90's from a child
So you click a button and - it crashes.
You restart the software.
You type something like 'abc' in a 'numberfield' - it crashes.
OK ... now you start the application again and try to navigate to another view - and? of course it crashes again.
You are excited to finally open the source code of this masterpiece.

Thank you jesus, the 'dev' who did this, didn't forget to write every business logic in the code behind of the views.
He even managed to put 6 views into one and put all their logig in the code behind!
He doesn't know what binding is or a pattern like MVVM.
But hey, there is also no validation of anything, not even checks for null.
He was so clever to use the GUI as his place to save data and there is a lot of parsing going on here, every time a value changes.
A thread must be something he never heard about - so thats why the GUI always freezes.

You tell them: It would be faster to rewrite the whole thing, because you wouldn't call it even an alpha. Nobody listenes.
Time passes by, new features must be implemented in this abomination, you try to make the cripple walk and everyone keeps asking: 'When we can start the new software?' and the guy who wrote this piece of shit in the first place, tries to give you good advice in coding and is telling you again: 'It was almost finished.' *facepalm*
And you? You would like to do him and humanity a big favour by hiting him hard in the face and breaking his hands, so he can never lay a hand on any keyboard again, to produce something no one serious would ever call code.

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!

I HATE working with MS Office products. Yes, Access, I'm looking at you, you backwards, whanabe database reject! You're invalid as a serious SQL database and retarded as an data application suite.

VBA, make up your MIND with your damn function calls! Either require me to use parenthesis or don't! I'm sick of this conditional parenthesis sh*t!

While we're talking about not making up your mind... screw 'sub', you half wit language! Either use functions like a real language or go the f&$k home and make room for a language that knows what it's doing!

Oh!!! WHY... WHY! do you have null AND... NOTHING?! Who... Who... WHO invented "nothing"?! And what sick joke are you playing at with isnull() and empty()??? How many damn ways so you need to test for "no value"?!?!

Access... That's right, I'm not done with you yet... How is it you've survived this damn long in the business world with all of the databases you corrupt? Sure, you suck as a real database, but at least have some freaking pride that people even USE you! How DARE your corrupt yourself with the regularity you seem to have! I wish my bowel movements were as regular as your database corruptions, for the love of humanity.

F$@k you, VBA! F@&k you, Access! F$#k you, MS Office! And Fuuuuuu$k YOU Microsoft for shoving these half assed reject tools down my throat!

I hope your cloud uses Access as a back end and gets some injection virus.

*Takes deep breath* need to say that.

My first poem for programmer girl 😘😘😘

My life is incomplete without you,
You are semicolon of my life

You are my increment operator,
you make my value increases

I am username and you are my password,
without you No one can access me

You are my initializer,
without you my life would point to nothing (NULL or “0”)

If I were a function you must be my parameter,
Because I will always need you

Can you be my private variable?
I want to be only one who can access you

You are my compiler,
My life wouldn’t start without you

You are my loop condition ,
I keep coming back to you

My love to you is like recursive function,
It will never ends & Will never enter into infinite loop

Forever and Ever

Rather than singling out one person, I wanna present what I see as incompetent/stupid/ignorant:
- no will to learn
- failure to follow the very specific instructions & later asking for help when they FUBR sth & not even knowing what they did to fuck up in the first place
- asking how to solve stuff, then ignoring the suggestions & doing sth totally against recommendations
- failure to remember most basic stuff, especially if not writing it down to look at later when needed
- failure to check logs & 'google' stuff before asking why something isn't working the way they want it
- after two weeks, asking me how feature xy works, mind you they coded it, not me
- asking me why they did something in a specific way - WTF, am I a mind reader?! Who designed that crap?! Me or you?!!
- being passive/aggressive & snarky when told to do something or being asked why isn't it done already
- not testing their shit properly
- not making backups when upgrading (production) servers
- not checking the input value, no validation.. even after many many debacles on production with null ref exceptions
- failure to admit they fucked up
- not learning from (their) mistakes

Best part about the covid19 manufactured crisis?
Liquor stores deliver. Worst part about liquor stores delivering? Needing to use their shoddy websites.

I've been using a particular store (Total Wines) since they're cheaper than the rest and have better selection; it's quite literally a large warehouse made to look like a store.

Their website tries really hard to look professional, too, but it's just not. It took me two days to order, and not just from lack of time -- though from working 14 hour days, that's a factor.

Signing up was difficult. Your username is an email address, but you can't use comments because the server 500s, making the ajax call produce a wonderfully ambiguous error message. It also fades the page out like it's waiting on something, but that fade is on top of the error modal too. Similar error with the password field, though I don't remember how I triggered it.

Signing up also requires agreeing to subscribe to their newsletter. it's technically an opt-in, but not opting-in doesn't allow you to proceed. Same with opting-in to receiving a text notification when your order is ready for pickup -- you also opt-in to reciving SMS spam.

Another issue: After signing up, you start to navigate through the paginated product list. Every page change scrolls you to the exact middle of the next page. Not deliberatly; the UI loads first, and the browser gets as close as it can to your previous position -- which was below that as the pagination is at the bottom -- and then the products populate after. But regardless of why, there is no worse place to start because now you must scroll in both directions to view the products. If it stayed at the very bottom, it would at least mean you only need to scroll upwards to look at everything on the page. Minor, but increasingly irritating.

Also, they have like 198 pages of spirits alone because each size is unique entry. A 50ml, 350ml, 500ml, 750ml, 1000ml, and 1750ml bottle of e.g. Tito's vodka isn't one product, it's six. and they're sorted seemingly randomly. I think it's by available stock, looking back.

If you fancy a product, you can click on it for a detail page. Said detail page lists the various sizes in a dropdown, but they're not sorted correctly either, and changing sizes triggers a page reload, which leads to another problem:

if you navigate to more than a few pages within a 10 or so second window, the site accuses you of using browser automation. No captcha here, just a "click me for five seconds" button. However, it (usually) also triggers the check on every other tab you have open after its next nagivation.

That product page also randomly doesn't work. I haven't narrowed it down, but it will randomly decide to start failing, and won't stop failing for hours. It renders the page just fine, then immediately replaces it with a blank page. When it's failing, the only way to interact with the page is a perfectly-timed [esc], which can (and usually does) break all other page functionality, too. Absolutely great when you need to re-add everything from a stale copy of your signed-out cart living in another tab. More on that later. And don't forget to slow down to bypass the "browser automation" check, too!

Oh, and if you're using container tabs, make sure to open new tabs in the SAME container, as any request from the same IP without the login cookie will usually trigger that "browser automation" response, too.

The site also randomly signs you out, but allows you to continue amassing your cart. You'd think this is a good thing until you choose to sign in again... which empties your cart. It's like they don't want to make a sale at all.

The site also randomly forgets your name, replacing it with "null." My screen currently says "Hello, null". Hello, cruft!

It took me two days to order.
Mostly from lack of time, as i've been pulling 14 hour shifts lately trying to get everything done. but the sheer number of bugs certainly wasted most of what little time i had left. Now I definitely need a drink.

But maybe putting up with all of this is worthwhile because of their loyalty program? Apparently if you spend $500, you can take $5 off your next purchase! Yay! 1%! And your points expire! There are three levels; maybe it gets better. Level zero is for everyone; $0 requirement. There are also levels at $500 and $2500. That last one is seriously 5x more than the first paid level. and what does it earn you? A 'free' magazine subscription, 'free' classes (they're usually like $20-$50 iirc), and a 'free' grab bag (a $2.99 value!) twice per month. All for spending $2500. What a steal. It reminds me of Candy Crush's 3-star system where the first two stars are trivial, and the third is usually a difficult stretch goal. But here it's just thinly-veiled manipulation with no benefit.

I can tell they're employing some "smarketing" people with big ideas (read: stolen mistakes), but it's just such a fail.

The whole thing is a fail.

Even during games, I find bugs in it...
Just found NULL in FIFA GAME.
Wonder which object failed to pass it's value

The default value... 😂😂😂

Java:
Integer value = null;

value + 100 --> null100

😒

After 'Dev' deployed a service using Azure ServiceBus, a particular queue/client was receiving errors.

Dev: "Looking at the logs, client is getting faulted."
Me: 'What is the error being logged?'
Dev: 'Client is faulted'
Me: 'No, that is our error when the client is either unable to connect or there is an exception in the middle of sending a message. What is the exception from Azure?'
Dev: 'Client is faulted. That's it. I'm going to have to re-engineer the code to implement a retry policy.'
<OK, I smell someone cooking up some solution finding, so I dig into the logs a little further>
Me: "Looks like an invalid connection string. The actual exception being thrown and logged is from the Azure client connection string builder. The value cannot be null."
Dev: "No, I'm looking right at the connection string in the config. Looks fine."
Me: "Looks correct on your machine, but what is actually being deployed to the server?"
<I could tell he was getting agitated>
<Dev clicks around, about 10 min. later>
Dev: "Aha!..I found it. The connection string in the config on the main branch is wrong, in fact, the entry is missing."
<dev fixes, re-deploys, life is good, I document the error and the root cause>
Boss: "Great job Dev."

*sigh* ..go teamwork?

Who the hell decided to put 'null' in JavaScript when there is already an 'undefined'
...😤😡...
Like one empty value isn't enough

Three months into a new job, as a senior developer (12+ years experience) and updated an import application.

With one small update query that didn't account for a possible NULL value for a parameter, so it updated all 65 million records instead of the 15 that belonged to that user.

Took 3 people and 4 days to put all the data back to it's original state.

Went right back to using the old version of the apllication, still running 2 years later. It's spaghetti code from hell with sql jobs and multiple stored procedures creating dynamic SQL, but I'm never touching it again.

OMFG I don't even know where to start..
Probably should start with last week (as this is the first time I had to deal with this problem directly)..

Also please note that all packages, procedure/function names, tables etc have fictional names, so every similarity between this story and reality is just a coincidence!!

Here it goes..

Lat week we implemented a new feature for the customer on production, everything was working fine.. After a day or two, the customer notices the audit logs are not complete aka missing user_id or have the wrong user_id inserted.
Hm.. ok.. I check logs (disk + database).. WTF, parameters are being sent in as they should, meaning they are there, so no idea what is with the missing ids.

OK, logs look fine, but I notice user_id have some weird values (I already memorized most frequent users and their ids). So I go check what is happening in the code, as the procedures/functions are called ok.

Wow, boy was I surprised.. many many times..
In the code, we actually check for user in this apps db or in case of using SSO (which we were) in the main db schema..
The user gets returned & logged ok, but that is it. Used only for authentication. When sending stuff to the db to log, old user Id is used, meaning that ofc userid was missing or wrong.

Anyhow, I fix that crap, take care of some other audit logs, so that proper user id was sent in. Test locally, cool. Works. Update customer's test servers. Works. Cool..

I still notice something off.. even though I fixed the audit_dbtable_2, audit_dbtable_1 still doesn't show proper user ids.. This was last week. I left it as is, as I had more urgent tasks waiting for me..

Anyhow, now it came the time for this fuckup to be fixed. Ok, I think to myself I can do this with a bit more hacking, but it leaves the original database and all other apps as is, so they won't break.
I crate another pck for api alone copy the calls, add user_id as param and from that on, I call other standard functions like usual, just leave out the user_id I am now explicitly sending with every call.
Ok this might work.

I prepare package, add user_id param to the calls.. great, time to test this code and my knowledge..

I made changes for api to incude the current user id (+ log it in the disk logs + audit_dbtable_1), test it, and check db..
Disk logs fine, debugging fine (user_id has proper value) but audit_dbtable_1 still userid = 0.

WTF?! I go check the code, where I forgot to include user id.. noup, it's all there. OK, I go check the logging, maybe I fucked up some parameters on db level. Nope, user is there in the friggin description ON THE SAME FUCKING TABLE!!
Just not in the column user_id...

WTF..Ok, cig break to let me think..

I come back and check the original auditing procedure on the db.. It is usually used/called with null as the user id. OK, I have replaced those with actual user ids I sent in the procedures/functions. Recheck every call!! TWICE!! Great.. no fuckups. Let's test it again!
OFC nothing changes, value in the db is still 0. WTF?! HOW!?

So I open the auditing pck, to look the insides of that bloody procedure.. WHAT THE ACTUAL FUCK?!
Instead of logging the p_user_sth_sth that is sent to that procedure, it just inserts the variable declared in the main package..
WHAT THE ACTUAL FUCK?! Did the 'new guy' made changes to this because he couldn't figure out what is wrong?! Nope, not him. I asked the CEO if he knows anything.. Noup.. I checked all customers dbs (different customers).. ALL HAD THIS HARDOCED IN!!! FORM THE FREAKING YEAR 2016!!! O.o

Unfuckin believable.. How did this ever work?!

Looks like at the begining, someone tried to implement this, but gave up mid implementation.. Decided it is enough to log current user id into BLABLA variable on some pck..
Which might have been ok 10+ years ago, but not today, not when you use connection pooling.. FFS!!

So yeah, I found easter eggs from years ago.. Almost went crazy when trying to figure out where I fucked this up. It was such a plan, simple, straight-forward solution to auditing..

If only the original procedure was working as it should.. bloddy hell!!

In PHP (yes, it's a language I... don't hate) I've always hated exceptions. They're like GOTO, in an OOP world with interfaces and contracts, try/catch is really odd as it breaks a promise about returning with a typed value.

But you can now do this in PHP8, which comes pretty close to Maybe/Either monads (Option, Result whatever it's called in other languages):

function getUser(): User | UserNotFound

PHP8 unions don't come with the same strong guarantees as in other languages but *pets PHP gently on the head* you did well, my boy.

Now I would really love it if PHP9 could do:

function getUsers(): Collection<User>

Type Tree<T> = Null | Node<T>;
function 🎄(): Tree<Branch<Ornament|Light|null>>

YOU MEAN TO ACTUALLY FKN TELL ME IT TOOK YOU 3 DAYS TO FIGURE OUT AN "QueryFailedError: null value in column "id" violates not-null constraint" ERROR??? GTFO. These fkn "fullstack" consultants man...

Dear Panicked Managers,

We are behind. We all know we are behind, and I would love to spend 10 hours fixing our shit.

Instead, your shit riddled brains decided that WAY too many demos, with practice demos, are the correct move! We are wasting 8 hours a week, per person working on them! That means we lose a day of development, but you are not moving deadlines and still complaining about the amount of throughput!

In those 8 hours a week, we could all build the new features, and you could throw an orgy, do lots of cocaine, beat hookers to death, do whatever CEOs do! Instead, you call us to all gather around and listen to you bitch that shit isn't getting done...

Sincerely,
Pissed Off

Why does MySql least and greatest functions return null if any of the arguments are null? Who was the genius behind the idea that it's the best way to implement it, and to change this behavior in a minor version?

Why does MySql return bigint when i convert a value to integer?

Why does MySql exist?

My Favorite Senior Dev: Hmm, I don't understand this error.

Neighboring, Competent SQL Developer Coworker: What does it say?

Senior Dev: It says, "Cannot insert the value NULL into column 'person', table 'PEOPLE'; column does not allow nulls..."

*5 minute silence*

This customer's dev is going to be the end of me. I had to explain to him why it doesn't make any sense to return a value after throwing an exception.

In a function that was supposed to insert a record amd return its id, in the error handling code:

catch(Exception ex) {
//logs the exception
throw ex;
return - 999; //this code will NEVER be reached, and why the f.... - 999?
}
The customer wants us to develop the project together, but he won't listen and always write whatever he wants. Some might be differences in taste. Like me preferring
if(condition) {
return a;
}
return b;

And him preferring :

Foo result = null;
if(condition) {
result = a;
} else {
result = b;
}
return result;

Ok, that I can accept. But things like the one I'm ranting about... I wont.

I'm starting to wonder what was he doing during his "9 years of coding experience"

Fuck everything about Microsoft Dynamics. I'm supposed to use the REST API to make a web front-end. I notice all of the data comes back codified.

null == 0.
boolean true == 100000000
boolean false == 100000001

except sometimes when

boolean false == 100000000
boolean true == 100000001

or other times

string "Yes" == 100000000
string "No" == 100000001
string "Maybe" == 100000003

Hang on. Is the system representing a 1 bit value with base 10 numbers? Did the client set this up like this? Holy crap every number corresponds to a unique record in a table somewhere. That means it only returns numeric values instead of strings and I have to figure out what the number means in the context of the table.

A "key" is user typed? So every time someone starts to make a new record it saves a new "key" without a record? So I can pull a bunch of "0" records if I pull sequentially? So basically I need to see all of the data in Dynamics to have any context at all for what is returned from the Dynamics API? Fuuuuuuuuuu

Just learned the previous dev team thought a db column with a value of NULL or "Y" was a great way to handle boolean values.

I want to explain to people like ostream (aka aviophille) why JS is a crap language. Because they apparently don't know (lol).

First I want to say that JS is fine for small things like gluing some parts togeter. Like, you know, the exact thing it was intended for when it was invented: scripting.

So why is it bad as a programming language for whole apps or projects?

No type checks (dynamic typing). This is typical for scripting languages and not neccesarily bad for such a language but it's certainly bad for a programming language.

"truthy" everything. It's bad for readability and it's dangerous because you can accidentaly make unwanted behavior.

The existence of == and ===. The rule for many real life JS projects is to always use === to be more safe.
In general: The correct thing should be the default thing. JS violates that.

Automatic semicolon insertion can cause funny surprises.
If semicolons aren't truly optional, then they should not be allowed to be omitted.

No enums. Do I need to say more?

No generics (of course, lol).

Fucked up implicit type conversions that violate the principle of least surprise (you know those from all the memes).

No integer data types (only floating point). BigInt obviously doesn't count.

No value types and no real concept for immutability. "Const" doesn't count because it only makes the reference immutale (see lack of value types). "Freeze" doesn't count since it's a runtime enforcement and therefore pretty useless.

No algebraic types. That one can be forgiven though, because it's only common in the most modern languages.

The need for null AND undefined.

No concept of non-nullability (values that can not be null).

JS embraces the "fail silently" approach, which means that many bugs remain unnoticed and will be a PITA to find and debug.

Some of the problems can and have been adressed with TypeScript, but most of them are unfixable because it would break backward compatibility.
So JS is truly rotten at the core and can not be fixed in principle.

That doesn't mean that I also hate JS devs. I pity your poor souls for having to deal with this abomination of a language.

It's likely that I fogot to mention many other problems with JS, so feel free to extend the list in the comments :)

Marry Christmas!

GOD ALMIGHTY I HATE SWIFT & XCODE...

Why the fuck does it take a horrendous amount of time to muck about with layout constraints. Why the heck does xcode choose to add constraint layouts to elements that already have pissing constraints! Why does dealing with something as trivial as tables have to be so god damn fucking involved when HTML and CSS let me create and style tables in fuck all lines.

And what the hell is up with how pissing long xcode takes just to figure out that 1 extra line of code I've just added. You jump to another file and xcode finally decides to be an ide again and bitch at the fact that you've forgotten to add some parameter or that they've decided to rename paramter "x" since version fuck nows what.

Working with abstract classes is fun, lets use protocols (because interfaces are too old school) and then lets tack on something we call extensions and then lets make people piss about with convenience initializers.

And lord almighty, what the fuck is up with casting, what all this ?! BS. What's wrong with just checking if the value is null in the first place, or whats wrong with giving something an initial value, oh because having to unwrap shit is more elegant right??

And good god, I need to own a fucking cinema screen just to have the storyboard open, there's less fucking panels on the Sistine Chapel ceiling
then there is in xcode.

Standing in the balcony, staring at the setting sun, I wonder to myself, "What does having a null value REALLY mean??🤔"

Guess who forced unwrapped Nullable value after making sure it was null... Yup that was me

(ಥ,_｣ಥ)

(ノಥ,_｣ಥ)ノ彡┻━┻

FUCKING PROMISE WONT FUCKING RESOLVE SO MY FUCKING CODE KEEPS FUCKING RETURNING A FUCKING NULL VALUE FOR FUCKING FUCKS SAKE IT REALLY SHOULDNT BE THIS FUCKING HARD TO RESOLVE A FUCKING PROMISE WITHOUT FUCKING CRASHING MY GODDAMN SERVER

Started a job as a full stack developer. My first task was shocking! Do these small edits on this backend script that collects stuff from one database and edits the entries in another... piece of cake so far!

Here is the project on the TFS...
HOLD ON! IS THIS VISUAL BASIC?!!
I came here to do .Net framework development and .Net Standard... I wasn’t told that there will be VB, I have never used vb.net before.

Now... that I’m going to maintain this script in the future, I decided to rewrite it in C#, few things I learned on my journey of doing this:
1- There is an access modifier in VB called Friend
2- There is a data structure/type called Collection, it’s a value,key pair! Not key value pair... Value first, then key!!
3- Do you know how null is null everywhere?!! In VB they call it Nothing! Yes, as in...
if(myVar == nothing)
{
//stuff
}
Asking the guy responsible for that choice... he thinks VB is easier to read than C#
I DONT WANT YOU TO READ IT, I WANT IT TO MAKE SENSE AND WORK WITH THE REST OF THE C# CODE WE HAVE!!

Company has a severe lack of fresh blood.

"let's recruit everyone who has an IQ over room temperature and barely passes the mark".

Me protesting bloody murder cause I know that the idea is not just profoundly dumb, but frustration from high staff turnover takes a toll on *everyone*.

"nah can't be that bad".

Then the discussion started who could do monitoring and mentoring, so we can sort out the bad apples *quickly*.

Me reminding again that this is exactly what leads to a high staff turnover, as this is nothing else than "hire, hire - quickly fire".

Guess who won the award of being the mentor / monitor ....

*drum roll*

Come on, I know you would NEVER expect this.

Let me surprise you: M E.

Yeah. They chose the person that was absolutely against this idea...

Because that person is "most qualified for the task at hand and has the necessary qualifications".

Today was the first 4 h workshop with a new recruit.

The Lord has had zero mercy on me.

I started to mute myself after 30 minutes in regular intervals to just scream and curse the world.

How profound dumb a person can be amazes me.

Person has had a "very expensive 6 month boot camp course".

I was close asking if the boot camp course was in watching porn and wanking their brain cells out....

Git... Yeah he knew what he was doing...

Except that he messed up every commit by either not sticking to the companies format or - what I found funny the first 2 times, then not so much anymore - just writing a git commit message like a 15 year old teenage girl would write to their diary.

Programming. Oh yeah. He should be a programmer.

He had much Bootcamp.

Bootcamp expensive. Bootcamp good.

If someone is unable to iterate over an iterator... And instead starts creating an integer based array of a map's key name to then fetch the map value in an for loop based on the created key array.

Yeah. Bootcamp much good.

Creating DTOs...

It took an hour to write a DTO with him... Cause constructors are hard and it's even harder when you have to explain primitive datatypes in Java, null safety, constructors, NPEs, final, ...

Like really no experience at all.

The next week's will be amazing.

Either I get a valium drop or I'm gonna blow my head off, cause mentoring will drain the last bit of hope I had left in me.

Note that I do not blame the recruit (yeah he's dumb. But he has ZERO work experience, so it's not unexpected), I'm just too fed up with getting the poo crown despite being against the whole process.

I think the recruit could make it..........

But that I got the shittiest job ever is really haunting me.

I dunno how I survive the next weeks.

And this is just the first recruit... There will be more.

Don’t use an array with index to get a value without checking the length. Don’t use an object without checking for null.

You may know I love to hate tests. Well not the tests actually, what I hate is the TDD culture.

DBMS schema in my app dictates a key can either have a value, or be omitted - it can't be null, and all queries are written with that in mind (also they're checked compile-time against schema). But tester failed to mock schema validation, inserted a bunch of null keys with mock data, actually wrote assertions to check those keys are null (even though they never should be), and wanted me to add "or null" to my "exists" queries.

No, we don't need more tests, and you're not smart with your "edge cases" argument. DBMS and compiler ensure those null values can never exists in our DB, and they're already well tested by their developers. We need you to stop relying on TDD so much you forget about the practical purpose of the code, and to occasionally break from the whole theoretical independent tests to make sure your testing actually aligns with third-party services some code uses.

And no, we don't need more tests to test your mocks, and tests to test those test, and yo dawg, I heard ...

Checking the whole code for finding the null value. Gone through the process multiple times.
Oh boy, it was wasn't "personId", it was "personID".

I just love PHP. You can do so much awesome stuff with it. Here, let me show you:

How to READ a private member of an object:
$reader = \Closure::bind(function ($instance, $name) {
return $instance->{$name};
}, null, $instance);
$value = $reader($instance, $name);

How to WRITE a private member of an object:
$writer = \Closure::bind(function ($instance, $name, $value) {
$instance->{$name} = $value;
}, null, $instance);
$writer($instance, $name, $value);

See? Just like that. This is really amazing stuff. I don't know of any other languages that allow this.

Below is a transcript from work Slack today. Only the names and some code are changed. It ended up causing a bit of drama. DevRanters, what do you take from this?

---

Delivery Lead:
Hey Gang. What's the blocker for FEATURE-123?

Dev1:
FEATURE-122 crashed on iOS app when viewing Feature Introduction page.

Teach Lead:
I've talked about this with Dev1 on a side channel.
And diagnosed the stack trace.
It looks like there is/was some bad handling of a List in the Feature Introduction view logic.
But this is confined to changes that Dev2 is still working on.
(It's not present in master)
Dev2, what's your current position on this?

Dev2:
I have tested at my end with Dev1 but it seems to be working fine

Tech Lead:
There is a race condition related to the use of someList.first()
My guess is that theres a Flow of those lists defined, with an initial value of emptyList
And that on your machine, that Flow is updating with a new value quickly enough that it doesn't matter.
But on Dev1's, for whatever reason, it doesn't get there in time, hits the empty list and falls over.
The logic that's performing the first() needs to gracefully handle empty lists as well.

Dev2:
Where is that logic called?

Tech Lead:
Here's the stack trace Dev1 provided in our conversation earlier:
Caused by: kotlin.NoSuchElementException: List is empty.
...
at 3 iosApp 0x00000000 kfun:kotlin.NoSuchElementException#<init>(kotlin.String?){} + 00
at 4 iosApp 0x0000000 kfun:kotlin.collections#first@kotlin.collections.List<0:0>(){0§<kotlin.Any?>}0:0 + 000
...
at 9 iosApp 0x0000000 kfun:kotlin.coroutines.native.internal.BaseContinuationImpl#resumeWith(kotlin.Result<kotlin.Any?>){} + 0000

This line:
kfun:kotlin.collections#first@kotlin.collections.List<0:0>()
...says that it's first() being called on an empty list.

Dev1:
FYI: Dev3/Dev4/myself are seeing the same issue with the same stack-trace above.

Tech Lead:
So Dev2, have you introduced such a call?
Because I checked master branch and there isn't one, in that version of the file.
Ok, I'll check your working branch Dev2
...
Yes you have here:
var processed1 = someList.first()
var processed2 = someList.first()
...
Lines 123, 124.
Solution looks really straightforward guys.

Dev2:
Okay, I will fix that and push the change

Tech Lead:
Check if someList is empty and allow for generating / handling null processedValues in the view.

Now; I'm going to be straight with you here.
This issue has been discussed over several hours today.
I expect that either one of you could have gone through the process I did in the last 10 minutes above, and resolved it in the same way :point_up:

Dev2:
I went on a break and it's not reproducible on my machine

Tech Lead:
I didn't reproduce it on mine either.

Dev1:
Dev2 and myself are now on sharing screen to sort this issue out. Hope to update back later.

Tech Lead:
<Screen shot of diff with changed code>
:point_up: That change should do it.

Dev2:
Already have pushed the change.

Tech Lead:
...just seen it, is good - same approach :ok_hand:
Dev1 please let us know when tested on your machine.

Dev1:
That does it. It fixes the issues. Thank you, Dev2. I will pick it off from here.

Tech Lead:
Glad to hear it guys.

Dev1:
I have to say this that it is not because we are not working on the issue - Dev2 and myself (together with Dev3/Dev4) have been on this issue all this morning. It just difficult to connect the dot when it wasn't reproducable on Dev2's machine. I brought the issue up because I wanted to switch to working on other tickets while waiting for this to resolve. Still thank you largely for Dev2's work and your keen eyes that spot and resolve the issue quickly.

Tech Lead:
Noted Dev1.
I think the take-away has to be to read the stack-trace carefully... don't worry - we've all been guilty of not reading the error in full, at some point.
The stack trace said that the 'first' element is being referenced from an empty list - that's just logically impossible, right?
Looking for that call to first, we saw it wasn't in the code before, and is after (two of them, in fact).
So then we ask ourselves, how can we deal with an empty list - and then solution almost presents itself.
It didn't really take reproduction of the error to resolve.
Maybe working with a new tech stack creates an anxiety that every issue faced will have a complex solution related to that stack; but I think you'll agree, this particular issue really just required a deep breath and your trusty 'debugging skills 101'... don't lose them! :smiling_face:

Unity's "quirk" messed me up again. This time, I wanted the time when the key was pressed as precisely as possible, independent of the framerate.
So I put the input reading routine into the thread pool, which causes the first few readings to throw null reference exceptions. No biggie; the system needs a few moments to warm up. So, I try-catch that part.

But when I build the game, as soon as I reach the part where the game tries to read the input value, it hard-crashes before try-catch can act 🤦

Major rant incoming. Before I start ranting I’ll say that I totally respect my professor’s past. He worked on some really impressive major developments for the military and other companies a long time ago. Was made an engineering fellow at Raytheon for some GPS software he developed (or lead a team on I should say) and ended up dropping fellowship because of his health. But I’m FUCKING sick of it. So fucking fed up with my professor. This class is “Data Structures in C++” and keep in mind that I’ve been programming in C++ for almost 10 years with it being my primary and first language in OOP.

Throughout this entire class, the teacher has been making huge mistakes by saying things that aren’t right or just simply not knowing how to teach such as telling the students that “int& varOne = varTwo” was an address getting put into a variable until I corrected him about it being a reference and he proceeded to skip all reference slides or steps through sorting algorithms that are wrong or he doesn’t remember how to do it and saying, “So then it gets to this part and....it uh....does that and gets this value and so that’s how you do it *doesnt do rest of it and skips slide*”.

First presentation I did on doubly linked lists. I decided to go above and beyond and write my own code that had a menu to add, insert at position n, delete, print, etc for a doubly linked list. When I go to pull out my code he tells me that I didn’t say anything about a doubly linked list’s tail and head nodes each have a pointer pointing to null and so I was getting docked points. I told him I did actually say it and another classmate spoke up and said “Ya” and he cuts off saying, “No you didn’t”. To which I started to say I’ll show you my slides but he cut me off mid sentence and just yelled, “Nope!”. He docked me 20% and gave me a B- because of that. I had 1 slide where I had a bullet point mentioning it and 2 slides with visual models showing that the head node’s previousNode* and the tail node’s nextNode* pointed to null.

Another classmate that’s never coded in his life had screenshots of code from online (literally all his slides were a screenshot of the next part of code until it finished implementing a binary search tree) and literally read the code line by line, “class node, node pointer node, ......for int i equals zero, i is less than tree dot length er length of tree that is, um i plus plus.....”
Professor yelled at him like 4 times about reading directly from slide and not saying what the code does and he would reply with, “Yes sir” and then continue to read again because there was nothing else he could do.

Ya, he got the same grade as me.

Today I had my second and final presentation. I did it on “Separate Chaining”, a hashing collision resolution. This time I said fuck writing my own code, he didn’t give two shits last time when everyone else just screenshot online example code but me so I decided I’d focus on the PowerPoint and amp it up with animations on models I made with the shapes in PowerPoint. Get 2 slides in and he goes,
Prof: Stop! Go back one slide.
Me: Uh alright, *click*
(Slide showing the 3 collision resolutions: Open Addressing, Separate Chaining, and Re-Hashing)
Prof: Aren’t you forgetting something?
Me: ....Not that I know of sir
Prof: I see Open addressing, also called Open Hashing, but where’s Closed Hashing?
Me: I believe that’s what Seperate Chaining is sir
Prof: No
Me: I’m pretty sure it is
*Class nods and agrees*
Prof: Oh never mind, I didn’t see it right

Get another 4 slides in before:
Prof: Stop! Go back one slide
Me: .......alright *click*
(Professor loses train of thought? Doesn’t mention anything about this slide)
Prof: I er....um, I don’t understand why you decided not to mention the other, er, other types of Chaining. I thought you were going to back on that slide with all the squares (model of hash table with animations moving things around to visualize inserting a value with a collision that I spent hours on) but you didn’t.
(I haven’t finished the second half of my presentation yet you fuck! What if I had it there?)
Me: I never saw anything on any other types of Chaining professor
Prof: I’m pretty sure there’s one that I think combines Open Addressing and Separate Chaining
Me: That doesn’t make sense sir. *explanation why* I did a lot of research and I never saw any other.
Prof: There are, you should have included them.
(I check after I finish. Google comes up with no other Chaining collision resolution)

He docks me 20% and gives me a B- AGAIN! Both presentation grades have feedback saying, “MrCush, I won’t go into the issues we discussed but overall not bad”.

Thanks for being so specific on a whole 20% deduction prick! Oh wait, is it because you don’t have specifics?
Bye 3.8 GPA

Is it me or does he have something against me?

Long story ahead

Background:
I recently started a job in a smallish startup doing web development in a mostly js stack as an entry-junior engineer/dev. I’m the only person actively working on our internal tools as my Lead Engineer (the only other in house dev) is working on other stuff.

Now I was given a two week sprint to rebuild a portion of our legacy internal app from angular 1.2 with material-ui looking components with no psd’s or cut-outs of any kind to a React and bootstrap ui for the front end and convert our .net API routes into Node.js ones. I had to build the API routes, SQL queries (as there were plenty of changes and reiterations that I had to go through to get the exact data I needed to display), and front end. I worked from 9am until 11pm every day for those two weeks including weekends as our company has a huge show this upcoming week.

I finish up this past sunday and push to our staging environment. The UI is 5.5/10 as we’re changing all of our styling to bootstrap and I’m no ui expert. The api has tests and works flawlessly (tm).

So we go into code review and everything is working as expected until one tab that I made erred out and was written down as a “Needs to be fixed.”

This fix was just a null value handler that took three minutes and a push back to staging, but that wasnt before a stupendous amount of shit being flung my way for the ui not looking great and that one bug was a huge deal and that he couldnt believe it slipped through my fingers.

Honestly, I’m feeling really unmotivated to do anything else. I overworked myself for that only to be shit on for one mistake and my ui being lack-luster with no guides.

Am I being a baby about this or is this something to learn from?

When you spent two hours of debugging because that one variable somehow has the value of NULL which can't be because it is initialized with another value and you realized you mistyped the name on one of your procedures, so VBA automatically instantiates a new variable and initializes it

fuck me i guess

1. Commented code instead of actually cleaning it up.
2. Returning default return variables instead of rewriting obsolete code. (Generally if/else conditions with return). So instead of removing the if/else statements i return default value(null or empty objects). This is when the case of if/else will never arise.

Some Java code I looked through to figure out how to accurately rework a mapping of value intervals to status colors:

• 16 levels of indentation
• Calls an instance method one line before a null-check
• Assigns that same value to a new variable and null-checks it again
• Insistently loops over existing HashMaps' entry sets to find a value by key
• Stringifies a Gson object, parses back the string and then null-checks the result.
• Mixes up the 'leq' and 'geq' comparison operators twice, which is why I went to check the implementation in the first place.

And this wasn't even legacy code. It's from last year.

Every once in a while the flexibility of dynamic types comes back and bites you in the ars:

So I created method that returns the date significance (day, month, year) or null when no date is set.
I chose a class constant DAY with the value 0.
This is not a problem in if statements as I always use === but in this case a switch made more sense. And as you can guess no date set (NULL) was handled in the self::DAY (0) case... 😐😑😶 Silently resulting in wrong results when no date is given! #£#@$& (and other comic swearing symbols)

Even though php7 finally has decent type hinting resulting in much clearer defined API's we can still go very wrong.
More love to Go for less verbose static typing! To bad we can rarely use it at the office 😥

Me: so zero is an integer meaning it means the number value equivalent of nothing but it’s an integer and actually represents a number that exists. Null means the number doesn’t exist and is not an integer.

Idiot in the back seat: So ThEyR’re tHe SaMe

Java has the worst kind of union type where every method returns the union of Exception | null | value.

Spent quite some time debugging an odd problem.

A null check failed to trigger correctly, and when checking in eclipse I saw the null value.

Much digging later I finally noticed that the value wasn't null, it was "null", but eclipse doesn't quote strings...

The problem was that somebody at one time decided to convert an Integer to String by prepending an empty string...

Integer val=getInt()
return "" + val;

Why it is such a pain to scan nullable types on Golang database.sql

Now I have to chose between:

1- Using temporaty variable to hold the nullable value just to soon after check and set the zero value if it is null

2- Adding coalesce to my sql query for the zero values.

Did I mention that there are around 20 collumns that are nullable...

Been debugging a sp in oracle from 2 days a fucking sp of 2000 lines to see why it was not not giving desirable result. Turns out a fucking variable had a null value which was always satisfying the greater than condition an fucking up the flow. The fucking sp is being used since ages and nobody fucking noticed i mean what the actual fuck. And also the fucking indentation of the code how the fuck are u supposed to know which if ends where i mean come on put some fucking comments to your fucking code if u are gonna make it like it is gonna be the ultimate fucking sp which is being used god only know how many places.

Change my mind. Golang can be more difficult than it needs to be sometimes:

Find the first "non-null" value in an array:

Go:
Optional<String> result = Stream.<Supplier<String>> of(
() -> first(),
() -> second(),
() -> third() )
.map( x -> x.get() )
.filter( s -> s != null)
.findFirst();

Ruby:
@group_list.find { |x| !x["list"].blank? }

Shower thoughts: i wondering something silly, for example address 0xf006 points to address 0xf003 which has value of 0x0000 how did it know if it is a 0 or a NULL

Maybe I'm stupid, but I'm annoyed that there are no good ways to debug Blazor WASM.

It doesn't help to tell me that I got a null value, unless the error tells me which of my 50 variables is causing it

Well someone didn't check for null value 😂😂

We had C project in school about multi-process communication and syscalls. We worked in groups of three.
I made a "framework"(header file) with important prototypes and definitions of needed variable sizes.
One of group member decided to null his variable by bzero syscall (writes null bytes). He ignored my framework and typed literal "sizeof". Ofc nulled double the needed value and it nulled another variable with some TCP packet also.
Spend week trying to find what is wrong with it.
I hate group projects.

<?php
// This is the demo code of a PHP gotcha which took me some hours to figure out

$hr = "\n<hr>\n";
$JSON = '{"2":"Element Foo","3":"Element Bar","Test":"Works"}';
$array = (array)json_decode($JSON);

echo "Version: " . phpversion() . $hr;
// Tested on: 5.5.35 and 7.0.15

var_dump($array);
// Prints: array(3) { '2' => string(11) "Element Foo" '3' => string(11) "Element Bar" 'Test' => string(5) "Works" }

echo $hr;

// Prints three times: string(11) "Element Foo"

var_dump($newArray[3]);

Just askin:
If you have a method which returns a value from an array. What do you prefer in a case when the item is not found?
A)Throw an exception
B)return null
C)return a special value like a null object or some primitive type edge value like Integer.MIN_VALUE

The bug: Some string values for an identifier property in the data objects are being sent from our frontend prefixed with a '0'. Sometimes. When it happens, it usually gets stripped away again by the time it's passed to our backend. But not always.

This 0 is never explicitly set anywhere. I even searched for a few variants of " = 0" in both the frontend and backend projects without receiving any results. You might already be suspecting where this is going.

So it turns out.

The data object which holds this value is being initialized in the aspnet (don't ask) backend and passed to the frontend, which then hydrates it. This value is always an integer number, albeit incidentally so which is why string is used as the actual type. When this object is initialized, it's hardcoded with an anonymous type where this property is set as int because I guess someone figured "it's always an int though". Being a typed language, primitive scalars can't be null objects which means the property's value becomes the concrete int 0.

Okay weird. I can think of better ways of doing this but let's just set it to string as I can't start overhauling things right now. Let's just go find where this value is somehow concatenated into the incoming parameter.

You see, this happens because at the point where the frontend sets this value, it may be an int or string depending on where it came from, and I guess someone figured that in order to cast it to string you just go prop += arg seeing as the prop is empty string and all. Because explicitly casting it or - as much as I get a rash whenever I see it - going prop = "" + arg would be too verbose and unoriginal.

Bonus round: How come the 0 only sometimes made it all the way to our backend? The thing is that this bug has been fixed before. The fix is that because this string is "always" an int, you can parse it to int before passing it to the backend in case it has leading zeroes. This path is only taken in certain views because someone forgot to copypaste their fix into all the places this is repeated.

Sometimes you find a bug and you are just somehow more grumpy after fixing it.

I had to contact technical support for an API. I’m pretty sure I was emailing with a bot because I was getting all sorts of stupid replies.

Me: I’m using your SDK for language X. It’s returned null for some properties. In the user portal, I can see there are values for those properties for the transaction. I don’t know why I’m not receiving them on my end.

Tech Support: Hi! I see the following was sent in the API response. [Sends api response to me.] You can also go the the portal to see those values.

Me: Yeah, I know. You just repeated everything I wrote to you. I don’t want to go to the portal. I told you I want to figure out why your SDK doesn’t seem to map those properties correctly when I receive the api response.

TS: Let me look at the docs. I think you need to send the properties you want in your request in order to get them back in the reply from the api. Such as <property>value<property> in the xml message.

🤨 The docs do not say that. They don’t even imply that.

Me: What the fuck?! That makes absolutely no sense. We have already established that the api **is** returning values for those properties. I want to troubleshoot why your SDK is mapping them as NULL.

So. Spent most of the morning furiously trying to work out why I wasn't getting a reasonable response from my Rest Service "RS", calling it from some other system. Only got something vague along the lines of "value must not be null". Both systems are set up on my local machine, IIS bindings set up all correct and URLs and authentication settings double and triple checked. I was doing a lot of work on RS six months ago so it just had to be set up right.

Forgot I got a new machine a couple of months ago and never built the WS .dlls. -_-

Hmm.. Who could've thought `where rows_numbered.rownum = grouped.item_index` would ever yield a null...

Sometimes I can be such an idiot

if (value == null)
doSomething()
else
failGracefully()

Am I wrong to think my senior using an expiry date value null as forever weird or is this common practice?

It's so frustrating to explain rxjs pitfalls to the manager.

To avoid the diamond problems and glitches caused by combineLatest and debounceTime(0), I decided to use single stream with nested reactivity.

Then the manager asked me to use withLatestFrom instead of combineLatest.

Sure withLatestFrom makes sense to the original author, when the original author is able to remember the reactive graph and put proper dependencies to combineLasted/withLatestFrom accordingly, but anyone else who touches the component later needs to retrace the reactive graph to avoid the glitch. Sometimes it's just impossible when many dependencies are derived from combineLatest+debounceTime(0). When no one is trained to code reactively, I don't expect people to know where to put a dependency. After many trials and errors, the only way to avoid the diamond problem is to use nested reactivity where child streams are created within root stream each time root stream emits.

The mentioned manager put all sorts of side effects in observable chains. The manager keeps saying the stream is too large when their subscription functions (sometimes nested) are way worse with litered mutations everywhere. Anything in observable can be traced by go to definition but tracing side effects usually requires global searches.

Recently, he put startWith to the end of a synced stream to fix a bug where button would collapse when there is no content (initial null emission). Rather than fixing the default height, he thinks using startWith(defaultLabel) is a good idea. Of course, he doesn't know that a synced stream should only emit 1 value on new subscription and that extra emitted value will cause rxjs glich down the pipe.

How could you calculate: 2a+7*2b when a and b is a nil value. Math aren't logic...

Crystal reports, when given a null value into a display string, will just ignore everything and output a blank.

Random error that was occurring in prod discord authentication for new users (only in prod):

It wasn't returning the discord ID of the user logging in (only in prod). This should not even be possible if the user authenticates. So the null value from the ID was used and returned the first user in the DB (I know, weird mongodb edge cases). It should have returned null for the user searched not the first user in the DB wtfff.

Anyways, new users logging in would be logged in as me. Bahahah

Pushed the fix. All is good in the hood.

Biggest deceit in Java developer's life : this value can never be null, leave that extra null check.

In Flutter Why this keep prompting to me

"'package:flutter/src/widgets/text.dart':
Failed assertion: line 378 pos 10: 'data != null'"

I tested it the value is not Null and i tried flutter clean nothing change

I've been sitting here staring at extension types and I wonder, what if I had a partial file with partial data ?

In general one could say that in every case where say a header is missing that is ALWAYS going to have some identifying characteristics even given a characteristic statistically frequent pattern of data, that there is always a null value that appears as total chaos.

But I wonder, is there a way beyond simply trying every goddamn possible combination of things until meaningful data is extracted to identify a file by its content when part of that content that is usually used for such a purpose, is missing ?

What kind of application or technology would be required for this ? Certainly not neural networks, but obviously some kind of ai right ?
