Welcome to JavaScript where
Number.isInteger(0.9999999999999999) is false and
Number.isInteger(0.99999999999999999) is true11 -
There are two kinds of people:
those who write
if foo.isBar() {
foo.setBar(false)
}
else {
foo.setBar(true)
}
Vs
those who write
foo.setBar(!foo.isBar())
Only good programmers will understand😢😊31 -

This is not a joke. This is not something I wrote to be funny. This is not found randomly off the internet. This is a real part of the project I inherited: a function that not only is more cumbersome to use than the simple <Array>.contains that it wraps, but rather than returning the boolean result from the function, sends it through an if statement and returns hardcoded true and false values for... Good luck? I guess?

GUYS WE HAVE BEEN WRITING FOR LOOPS IN JAVA WRONG THE WHOLE TIME. Here is how it should be done correctly...
int i = 0;
for(;(i<10) ? true : false;)
{
i++;
System.out.println(i);
}
Jokes aside though does anyone have any more horrid ways to write this?20 -

I messaged a professor at MIT and surprisingly got a response back.
He told me that "generating primes deterministically is a solved problem" and he would be very surprised if what I wrote beat wheel factorization, but that he would be interested if it did.
It didnt when he messaged me.
It does now.
Tested on primes up to 26 digits.
Current time tends to be 1-100th to 2-100th of a second.
Seems to be steady.
First n=1million digits *always* returns false for composites, while for primes the rate is 56% true vs false, and now that I've made it faster, I'm fairly certain I can get it to 100% accuracy.
In fact what I'm thinking I'll do is generate a random semiprime using the suspected prime, map it over to some other factor tree using the variation on modular expotentiation several of us on devrant stumbled on, and then see if it still factors. If it does then we know the number in question is prime. And because we know the factor in question, the semiprime mapping function doesnt require any additional searching or iterations.
The false negative rate, I think goes to zero the larger the prime from what I can see. But it wont be an issue if I'm right about the accuracy being correctable.
I'd like to thank the professor for the challenge. He also shared a bunch of useful links.
That ones a rare bird.21 -

Python: I hate the way it uses True/False over true/false
Java: Static. Just fuck static. oh and System.out.println(), why the fuck did they make the basic print function so long to write.
C#: I despise the way the curly braces get automatically put under the function declaration rather than beside it since it's a language style thing.
C: the inability to declare vars in altho declaration of a forloop. Although I think C11 let's you do this.
Javascript: Fucking prototypes.
Coldfusion: it runs like an elephant. Slow and heavy.
Go: The way the compiler won't let you have unused variables/imports. Pain in the ass for testing.17 -

Where I work, in our database, we use 3 to indicate true and 7 to indicate false and 0 is true but null is false
In another table, we use 'P' to indicate true and 'I' to indicate false and 'Y' is also false and null is false
And the most used table, we also use 'Y' to indicate yes and 'N' to indicate no, but null is also Yes.
We also store integers as varchar in a live table, but stays an integer in all the other tables. I hope I'm not there when the number of digits exceeds the varchar limit.
These are all live and used in production all created by my boss, the head of IT.8 -

Someone gave me a web method that return a boolean.
The Boolean tells me if the operation went well.
True means everything went well
False means something went wrong
But
It throws exception when something went wrong.
Basically they implemented a Boolean system to check if everything is alright but I also have to add a try/catch if something is not right.9 -
Developers who writes something similar
if (count >= 0) { return true; }

My Javascript professor explained Boolean to me using an allegory about pizza: "If I give you pizza, under what condition do you eat it? Your hunger must be true or false. Boolean does the same thing, but with things less exciting than pizza."

Less rant, more mildly interesting Java trivia.
Integer i0 = 3; Integer i1 = 3;
Integer i2 = 300; Integer i3 = 300;
i0 == i1 is true as expected
i2 == i3 is actually false
Java caches -128 to 127 Integer objects for faster perf so when you're inside that range, the objects are indeed the same, but because == checks object equality, the Integer outside of the range is not cached and had to be initialized, so i2 and i3 are two different objects.
You can totally break some tests this way :)9 -

Stupid HTML checkboxes! It's always annoyed me that you can't just set checked to true or false, but have to remove the property altogether to uncheck a checkbox. Better still would be if you'd only need to set the value to 1 or 0, and the checked or not would sort out automatically. Yes, there are frameworks to handle it, I know. But if checkboxes had been designed right from start, a framework or any sort of special cases would not be needed. You've got love HTML, but things like this make it ugly.6

Anyone else developed a habit to structure verbal allday Argumentations in your head in Code syntax? Helps me alot to follow ones logic. Except when I'm arguing with my girlfriend. Sometimes setMood(angry) gets randomly called (bug?) and then every if statement seems to be valid, eventhough it should return false. An inputstream that contains my outputstream is initialized but .readLine() is never being called. Instead, the outputstream to my inputstream is being overly abused. Once we get dive deeper into our if-statement we will find a while loop with a mysterious flag. Noone knows it's origin. The while loop keeps printing out random concatenated strings until it overflows your own capacity. I would have said its while(true) but in fact there must be a timer in another very hidden thread or something that sets our flag to false. The other and only way I know to exit that loop is to call apology() 100 times (maybe a variable sets the boolean that could be deeply buried in her projectstructure like this CONST.VALUES.getMood().getRealMood().getTrueMood().TRUTHCONTAINER.angryMode=true)..
I wish I could get a stressball so I can continue theorycrafting and debugging. Its 4.30 am now, my better side is snoozing next to me. I bet making this a pseudocode would be fun.

Two actual lines of code I stumbled upon...
static ArchiveAbstract ARCHIVE_TRUE = new ArchiveTrue();
static ArchiveAbstract ARCHIVE_FALSE = new ArchiveFalse();
Ok you might think, what is going on? Searching for it's usage yields exactly a single case:
if(someVar instanceof ArchiveTrue ? true : false)
So someone managed to introduce 3 new classes... instead of using a simple boolean.

"No, but they must be sent in as strings"

So our new teacher executes console applications (C#, .NET) with the VS debugger attached (F5) instead of just letting it execute normally (CTRL + F5).
He complained about the output not showing up (he still gave me full score at least) That's because executing with F5 simply ends the program after Main() is done executing, while CTRL + F5 leaves the window open until you press a key, saying "Press any key..."
So here's what I'm gonna put at the very bottom of Main() in future:
if (System.Diagnostics.Debugger.IsAttached)
{
Console.CursorVisible = false;
Console.WriteLine("Press any key...");
Console.ReadKey(true);

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.

boolean true == 100000000
boolean false == 100000001

boolean false == 100000000
boolean true == 100000001

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? Fuuuuuuuuuu10 -
I’m all for writing boolean statements that are readable, quick to grasp the real life case they’re representing and align with the spec rather than being ultra-reduced, but sometimes the spec is written by someone who clearly can’t reduce logic. So when the spec says “if it’s not the case that any of them are false” and you write:
!(!a || !b || !c || !d)
then I think you should try harder. At least put a note against the spec to say “i.e. if they’re all true” and then write the sensible code. Just think of the poor developer that might have to augment your code at a later date and has to follow and intercept that shite. -

It uses a ternary operator which returns true if the result is true and false.. you guessed it... if the result is false.
WHY NOT JUST RETURN THE FUCKING RESULT!!!
What. The. F#%#....2 -
When a condition is true and false at the same time...
var_dump(0 == "x"); // true
var_dump(!0 == " x"); // true
WTF?!
I started using the === more often...5 -

Someone mentioned being frustrated with people who answer "either/or" questions with "yes". I figured out why. They are not human. They are a robot and their processing of language is failing.
A simple question:
Q: The car is red or the car is green?
A: Yes
Breakdown:
The car is red. Yes, True
The car is green. No, False
The car is red OR the car is green.
True OR False
True || False = True
True = Yes
So they dissected the language like a computer treating "or" as a logical OR. This proves they are a robot pretending to be human. They failed the Turing test.7 -
This is the most wtf thing that happened me with Javascript, I had a regular expression and it caused bugs only with 4 digits long words, then I just noticed this:
/^.{3}$/.test(null) // false
/^.{4}$/.test(null) // true
What the fuck, I can't believe that who designed the .test method didn't think to avoid null coercion2 -
At first it seemed harsh, but then I learned that he committed code like
if (a == b)
return true;
else
return false;

So they are back, wanting another quick PR approved.
The PR:
```
let isDisabled = switch quantity > 0 {
| true =>
switch value !== "" {
| true => false
| false =>
switch inputStatus {
| Valid =>
switch inputData {
| Ok(a) => a !== 0.0 ? false : true
| Error(_) => true
}
| _ => true
}
}
| false => true
}
```6 -
And then, looking for the source of a bug in the code .... I randomly found this:
public bool IsOperationStarted { get; set; }
public bool IsOperationStartedTrue
{
get { return IsOperationStarted == true; }
}
public bool IsOperationStartedFalse
{
get { return IsOperationStarted == false; }

RDBMS class: I have to fucking attend every class even though our lecturer just reads slides from Oracle to us.
In order to pass that module, we have to take the exams on their shitty website full of stupid questions, I.e. "Oracle academy is beautiful? a) true b) false" (I put false and they obviously marked it as wrong, ffs).
Multi-user operative systems: I was the one teaching our lecturer stuff on Linux.
WHY THE FUCK I CANNOT STAY AT HOME AND BE FUCKIN PRODUCTIVE INSTEAD?!
The only fucking interesting class is Data Structures & Algorithms and they pretend that we also attend every other useless class. FUCK YOU!
PS: I know the 90% of the stuff they are trying to teach us because I actually want to learn something and I know how to use Google, but no, I have to waste 2 hours on the bus every single day I have lessons.6 -
Interviewer: Could you please make a class to force it create one instance at most?
Me: Sure!
(I didn't know the singleton pattern)
class A {
public static bool isCreated = false;
A() {
if(isCreated == true)
throw new Exception();
isCreated = true;
}
}5 -
After I read clean code I talked to a fellow developer about some concepts. Later I reviewed some code of him and he clearly got the concept (not)

Today I learned that for boolean HTML attributes, they are considered true if they're present on the element at all, regardless of their value. And that as a rule, you should specify the empty string("") in value.
This wounds me on a logic level since everywhere else in JS, "" is false.
What.

Fuck.
Seriously. Why?14 -

I have come up with a weight loss program with developers in mind. It involves scaring the crap out of your fellow developers while they work and play on a computer. When you are scared you expend a bunch of energy reacting to the scare. Any number of scare tactics can be employed. They can be surprise (jumping out), conversational (your fired type), screamer videos or programs, etc. The type of scare is up to you. Get creative.
I am calling this program: Boo-Lean
You can choose to use this program or not.5 -

(true||false) && true || false || (true && false) ... etc (continue for at least ten clauses four times as long)10 -

// Stupid JSON
// Tale of back-end ember api from hell
// Background: I'm an android dev attempting to integrate // with an emberjs / rails back-end
slack conversation:
me 3:51pm: @backend-dev: Is there something of in the documentation for the update call on model x? I formed the payload per the docs like so
{
"valueA": true,
"valueB": false
}
and the call returns success 200 but the data isn't being updated when fetching again.
----------------------------------------------------------------------------------------
backend-dev 4:00pm: the model doesn't look updated for the user are you sure you made the call?
----------------------------------------------------------------------------------------
me 4:01pm: Pretty sure here's my payload and a screen grab of the successful request in postman <screenshot attached>
----------------------------------------------------------------------------------------
backend-dev 4:05pm: well i just created a new user on the website and it worked perfectly your code must be wrong
----------------------------------------------------------------------------------------
me 4:07pm: i can test some more to see if i get any different responses
----------------------------------------------------------------------------------------
backend-dev 4:15pm: ahhhhhh... I think it's expecting the string "true", not true
----------------------------------------------------------------------------------------
me 4:16: but the fetch call returns the json value as a boolean true/false
----------------------------------------------------------------------------------------
backend-dev 4:18pm: thats a feature, the flexible type system allows us to handle all sorts of data transformations. android must be limited and wonky.
----------------------------------------------------------------------------------------
me 4:19pm: java is a statically typed language....
// crickets for ten minutes
me 4:30pm: i'll just write a transform on the model when i send an update call to perform toString() on the boolean values

I spent the whole day coding in python (usually I code in php or perl) and this language is a fucking joke. C'mon, why everything have to be done in such a weird way? And don't say it's python way because it's bullshit way. Want some examples?
", ". join(str(x) for x in array)
to join array of integers. wtf is that?
True|False
why in hell you need the first letter to be uppercase when your own fucking standard says to use lowercase letters in eg. var names and method names. why?
math.isnan(float(x))
to check if a variable (expected to be integer) is NaN. I won't fucking comment that...
Even prolog don't have such stupid things6 -
so i have to practice on codewars for homework and my code.. doesnt work! what a surprise. i was wondering if anyone could tell me whats wrong since yall are professionals. its probably a stupid mistake. this is the challenge: Implement a method that excepts three integer values a, b, c. The message return true if a triangle can be built with the sides of given length and false in any other case.

How do you usually design your service communication class?
I am working on a mobile app which contains talking to a REST service, I usually put all network calls in one class. Down side if it becomes a big class it becomes a pain to maintain. Any thoughts?
For a backend service I usually go with Repository design and it is working out well for me. But for mobile Apps I'd like to see if there is a better approach4 -

Here’s a snippet of code that I found in our production codebase. I found this while fixing a bug. This is not part of the bug though but I see this a problem. Should I say this to my senior that his logic is off here?
First he doesnt have to do explicitly strict comparison since the return type is boolean and it could be true or false. Also the returnUrl will alway be undefined because redirectIfUserLoggedIn is called first before it was set.
He dosent like me. Hell get mad for sure. I think ill let this go.

I get it. Functional code is still kind of considered the "new hotness" in languages like Java, but THAT DOESN'T MEAN YOU NEED TO CRAM IT IN EVERYWHERE FOR THE SAKE OF IT. If in doubt, *please* go for the simpler, classic option...
Just inherited a code base that's full of things like this:
Optional.of(getResult()).filter(s -> s.equals(true)).ifPresent(s -> callService());
Optional.of(getResult()).filter(s -> s.equals(false)).ifPresent(s -> logError());4 -
Someone tell me should I just give up because I'm stupid and simple shit escapes me or tell me bro calm the fuck down the guy is full of shit...
Dude says he can't verify 3rd statement in a nested IF - elseif logic because the third check for a false condition is the True condition in the first 2 statements.
So
If (mode) = manual and then
Data(g) /= Status1
Or else Data(g) = Invalid
Then
Do this thing that sounds cool
Elsif
Data(g) = Status1
And then Data(g) /= Invalid
Then
Do something else equally cool
Elsif (mode) /= manual
and then Data(g) /= Invalid
and then Data(g) /= Status1
Then
Do some less cool stuff

How do you deal with relatively complex Boolean logic requirements?
Here's a simple example, of which I missed 50% of the cases because it was non-intuitive to me:
A year is a leap year if:
- it is divisible by 4
- except it is also divisible by 100
- unless it is also divisible by 400
To my intuition, the logic tree is as follows:
if (year % 4 == 0) -> true
if (year % 100 == 0) -> false
if (year % 400 == 0) -> true
so I ended up with 3 cases and I initially missed all the others until I started coding.
The full solution is:
if(year % 4 === 0) {
if(year % 100 === 0) {
if(year % 400 === 0) {
true
} else {
false
}
false
} else {
true
}
true
} else {
false
}
}
I don't like it when I don't immediately see all logic paths.19 -

PHP are you freaking kidding me right now? Why are you forcing me to write ugly and meaningless code like this?
Today I just learned that boolval("false") will return true.
I'd deffo expect this from casting operators, but not from a function which even has val inside of its name.
What purpose is to have functions like these in language if they just serve as plain wrapper for casting operators

Why? It is a valid question so I was trying to resolve a bug in one of our components that uses a TreeList of DevExpress and on the event AfterNodeFocus we raise an event to update the current object selection by putting the node selection to true and updating other values as well.
Well it seems that every thing is OK so why the fuck is this thing not working????
After 30 minutes into the problem realized that the event SelectionChanged is raise in the end of the AfterNodeFocus. Then realized that the event was running twice. One when I was setting the node.selection = true and after the event AfterNodeFocus but the list of selections were different. So what I discovered is the event SelectionChanged raised after AfterNodeFocus is using node.selection = !node.selection.
So how do I fixed it?
Before finishing AfterNodeFocus I set the selection of the node to false and voila the selection of items works now.
Well after 5 hours into the problem lets try another thing.3 -
Not sure if other programming languages class a Boolean as an integer value buuuuuuut...
The amount of times I've seen people do code such as...
if(value == true) {
variable = "blah blah";
} else if(value == false) {
variable = "blah";
}
Instead of doing a simple 1D array and going...
variable = strings[value];
It drives me crazy, such a small thing that has no real benefit but... Ugh... Whyyyyyyy3 -

Sure, languages with automatic conversion to truthy and falsy values can be a pain in the ass, but in languages without that feature you need to use foo != true to see whether foo is either false or null. How fucking ugly is that?9

When elements of an union are distinguished by a boolean, VSCode's Typescript plugin can only do type elimination if I branch by "== true" and not if I just branch by the boolean.
This is because Typescript treats booleans as an union of the constants "true" and "false", and compile-time elimination can only be done if I use syntax that makes sense with unions. Logical evaluation, for some reason, doesn't.
The fact that this issue can even appear is deeply concerning.1 -

I'm writing a Python script to manipulate Excel files, I'm using the openpyxl module, does anybody know how can I check if a user input is in a column, I've done this:
newItem = input("What is the new item?")
for itemChecker in inventory["A"]:
>>>>if itemChecker == newItem:
>>>>>>>>item_on = True
>>>>if itemChecker != itemNuevo:
>>>>>>>>item_on = False
if the user input (newItem) is in the "A" column of the variable assigned to an Excel file called "inventory", the variable "item_on" is set equal to True, if the user input isn't in the "A" column, "item_on" is set equal to False
what am I doing wrong, I'm not getting any errors but it always says that the user input isn't at the "A" column (sets "item_on" equal to False) even when I know it is1 -
I'm developing an app for a client, but they are responsible for the APIs.
Which turns out is the biggest mistake of my life...
I don't know whether data types are unknown to them or they are just playing a sick game with my emotions.
They have a different data type depending on how they feel, e.g.
- a boolean can be true, false, 0,1 or 2...
- an array can be an array or just a single item...
Who in their right mind can do this?4 -

Sweet Zombie NullFuckingPointerException...
New Rule: When creating an API (I'm looking at you, Java), designers must include a boolean flag in the parameter list of any method which throws a NullPointerException.
If TRUE, this means that a NULL result is non-trivial and the method should therefore THROW an NPE.
If set to FALSE, this means that NULL is completely f*cking trivial so whenever there's a NULL result, just instantiate a new instance of the return type and return that, 'cause that's what was gonna happen in the catch block of the NPE anyways.2 -

For me it's about removing grey from my life. I make decisions about things and move on. It's either black or white, there's no grey, true or false. It can be a little odd for new friends. For example, a trak comes on the radio, someone asks me do you like this, well I have to really like it in which case it's brilliant or no it's shite. Why would i say it's ok as its so vague and doesnt reveal my true feelings about stuff. Sorry i am waffling on about bullshit, just waiting for the chemist to open in the pissing down rain.

MOBBING DICTIONARY - 3 -
Sentence (harsh public remark)
- You always want to do everything.
Purpose
- highlight a (true or false) defect of the target, a lie repeated thousands of time will become true.
Result
- whether or not that is true, everybody will start to see the target with that particular defect. Every action will be justified to correct the defect.
While it is often true that people at time have difficulty to delegate, usually the reason is not that they don't want to, but they don't know how.
The mobber want to remove the person rather than helping on the "how".
This strategy get the best result when the target is self aware, take the mobbing sentence as a constructive feedback and start to effectively delegate. He/she will contribute to make him/herself useless and could be later easily disposed of.1 -
Doesn't the existence of NULL in a language mean, that there cannot be a boolean type? Because a bool is defined by the fact, that it can have two possible values. Having NULL changes that.
Without NULL a variable of the type bool could be True or False, two possible values. With NULL is can be True, False or NULL, three possible values.
I hate NULL.18 -

Anybody watch the "Electric Dreams" episode called "Safe and Sound"?
This makes me think this is where we will end up with tech companies altering searches/websites for the individual. Making people believe things that are not true by representing false narratives. The actions of these individuals will reinforce narratives presented to the masses. There is already people finding that search engines and social media can sway elections by several percentage points. It seems like someone could use that same tech to target someone and turn them into a <fill in the blank here>. Urging them to some action. The rest of the world is like "WTF just happened?".

We have this C# class which is like the core of our entire business logic. If you are in another class and it doesn't contain an argument in the constructor and/or property of that core class you're gonna have a bad time.
That core class has lots of useful business logic bools, "IsSomething", "HasSomething" etc. However that core class has a parameterless constructor which is sprinkled dangerously throughout our app, meaning the object is often not initialised properly and it's a 2 day mindfuck to make sure your "IsSomething" bool is actually false and not just false because the other business logic that bool relies on wasn't initialised and the bool has never had a chance to be true.
It's difficult to trust even a simple "if' statement. And if you're somewhere were you've had a list of that core class passed in, you need to trace how the list was initialised to make sure all your bools have been set 😴4 -

On science and religion. Inspied by a comment in another rant, credits to @Commodore and @cjbatz
According to Godel's incompletness theorems, aritmetics is incomplete and inconsistent. Therefore, any science based on aritmetics (dude, like, every) is also.
Therfore, as a mathematician, I must accept that there are things that cannot be proven by current science, and that there are statements that are true and false at the same time in current science.
So, science can't prove religious beliefs? It cant prove P vs NP either. It might someday. Science couldn't prove earth wasn't flat for a looong time. Or Pythagoras theorem.
But more importantly, if science can prove something, doesn't mean it can't prove the exact oposite.
This way of thinking allows for any and all ridiculous beliefs, under the shield of "it might be proven one day" or "doent't mean opposite isn't true also" but kerp in mind that there are complete and consistent sciences and proofs in them. Check if something's been proven to exist or not exist without doubt.11 -

I was working on a bug in a parser for the response from an api which returns 'n/a' when a certain measurement isn't available. The code was "if ($value == 'n/a')" and when this was true the value was rejected (language is php).
Some of you may instantly understand the problem here. I didn't. Some of the measurements were 0 which is ok, but for some reason it didn't accept them.
Then I discovered the bitter truth:
0 == 'n/a' is true!
Apparently php tries to convert the string to a number to compare it and if it fails it returns false, so false == 0

We have a huge domain model in Java and something is really fucked up with our equals/hashcode implementations and know body can track it down.
I have suggested Lombok/Groovy several times but they didn't listen.
Anyways it is so fucked up, that map.contains(foo) returns false, although it is part of the map.
So we wrote something like this:
for (Entity e: map.keyset) {
if (foo.equals(e) {
return true;

What the Fun Javascript Part 2
With reference to my old rant : https://devrant.com/rants/1445754/...
An explanation to this...
In JS whenever it sees '==' it has a set of rules that it follows before comparing quantities...
One such rule is...
When we compare a number with a boolean using '==' it first converts boolean into number then compares the two quantities...
So in this case..
When we convert true to number we get 1 and when we compare 1 and 2 they are obviously unequal hence we get false...

Recently had trouble with some SQL. My tests would not pass, so I had to manually run it to debug it.
SELECT * FROM a JOIN b ON [...] WHERE b.foo NOTNULL
Yielded 0 of 3 rows. Expected 1
Tried querying WHERE b.foo ISNULL instead. Would have expected 2 of 3 rows, but got 1.
After googling i discovered that comparing with NULL does not return a true/false binary description, but may also return unknown if the type is not a NULL type, e.g. 42 ISNULL =" UNKNOWN

I declared a boolean variable to be public static in my android activity and assigned a false value to it outside the onCreate.
only one method can change its value to true, so once its executed
the value of the boolean variable was set to true even on a new launch after finishing the activity.
didn't know why but it happened.
solved it by assigning a false value in the onCreate method. -
When a child experiences extreme adversity, physical, emotional and sexual abuse, neglect and trauma; There are two possible outcomes.
1) Drug abuse, addicition, financial problems, depression, anxiety, isolation, bad grades and unemployment, early death or suicide.
Or if the child manages to survive, go past the adversity:
2) Become a superhuman. Experience entertainment, happiness in small things even more. Utilize dissociative identity disorder by achieving mental and physical prowess by false yet true belief of the persona.6 -

Was working as the only frontend developer ona project having 4 "senior" developers. They use Laravel to make an API feeding the angular app.
Why the documentation sucked?
Half the API call params where missing, and not one time did I come across an example stating that the API expects a boolean only to find out 20 minutes later that they mean int 1 or 0 not true or false. Best part however was sending arrays in POST by sending the elements as comma separated values (e1,e2,e3...). Oh and not documentation but while at it a rant... There are other response codes except 200 for fucks sake -

Hey database experts. MySql question:
I have a table with houses, there is the location, color, etc. Shall I make a column for the owner or make a separate table HouseToOwner - where I connect the id's? I have no idea why is it good practice but saw it in few cases. I have the same with the things inside like I would just make a boolean column for a TV-like haveTV - true/false. Tell me why to not fill everything in one table. thx17
