Interviewing a junior dev.
> Make this function return false.
> junior: deleted all code in function replaces it with return false;

Literally no words.........

!false

men==women returns false

"False Positive" and "False Negative" errors

Bring the funny...

Welcome to JavaScript where
Number.isInteger(0.9999999999999999) is false and
Number.isInteger(0.99999999999999999) is true

public boolean even( int num ) {
if ( num < 0 )
num = -1 * num;
while ( num > 1 )
num = num - 2;
if ( num == 0 )
return true;
else
return false;
}

Code: if(customer.primaryContract)

Boss: "just using a variable as a boolean isn't very readable"

Me:
if(!(!customer.primaryContract != !true).toString() == 'false')

Q : 1 is true and 0 is false. right??
A : 1

[] == []; // false
[] < []; // false
[] > []; // false
[] <= []; // true
[] >= []; // true

This is not false !

When you see a someone write this
if(condition){
return true;
} else {
return false;
}

function isTrueOrFalse(s) {
if (s == true) return true
If (s == false) return false
}

If (condition)
return true
else
return false
😂😂😂

200 OK
{ ok: false, error: "Not found", code: 404 }

!false
It's funny cause it's true 😐

I just encountered this:

switch (boolean) {
case true:
…
break;
case false:
…
break;
}

if( !condition ) vs. if(condition == false)

Pointless debate started with readability, turned into heated insults under 30 seconds 😂

int main()
{
bool NeedPoints = true;
int Points = 0;
if (NeedPoints)
{
Points++;
if (Points > 10)
{
CreateAvatar();
NeedPoints = false;
}
}
}

Q: 0 is false and 1 is true. Right?
A: 1

Me-
/ / / / / / / / /
if (bool == true)
{
bool = false;
}
if (bool == false)
{
bool = true;
}
/ / / / / / / / /

My friend-
/ / / / / / / / /
bool = !bool;
/ / / / / / / / /

*not a real story*

Typical JS
null > 0 //false
null == 0 //false
null >= 0 //true

Wtf?

!false, it's funny because it's true 😂

Shit fucking noobs

bool x = false;
bool not_x = x ? false : true;

Fucking pro noob shit!

This was typical for me:

Yesterday evening I was installing a webserver on my Raspberry Pi for experiments with WordPress. I began some days ago, but I had to stop because the downloads took at least to long.

So I started to logi in:

Username: Raspberry
Password: Pi
-> False Password

Wondering why it is not working a tried again. Same result. After some time I remembered that I changed my password.

Username: Raspberry
Password: Ih4G2tgY*
-> false password

*example
Tried again. Still false password. Then I remembered, that I used my another standard password.

Username: Raspberry
Password: U2gra94hY*
-> false password

After that I felt a mix of angry and helplessness. After some other failed attempts I gave up.

I formatted the SD-Card and installed Raspian again.I started my Pi

Username: Raspberry
Password: Pi
-> false password

My thought: WTF, why does this not work!!

This was the moment when I got the brainwave that the Username wasn't Raspberry, it's Pi.

Username: Pi
Password: Raspberry
-> access

Then I hated myself.

Refactoring legacy code when...

if _out == True:
r = True
elif _out == False:
r = False

return r

This rant is False.

if (condition == true && condition != false)

True | | False

Classmate: "why doesn't it work?"
The code:

if (false) {
return even;
} else {
return odd;
}

Why have you not yet approved my PR?!!?!

The PR:

```
role.filter(elem => elem !== "view" ? elem !== "use" ? elem !== "admin" ? false : true : true : true)

#define TRUE false

bool success = false
if !success {
success = try()
}
if !success {
success = try()
}
if !success {
throw new GiveUpException()
}

not the worst by itself, except I keep finding them everywhere

if(thingThatIsTrue == true) {
// omfg
}

or it's inbred cousin

if(!thingThatIsTrue == false) {
//herpa derp
}

?notFullScreen=false

The evilest thing to do in a C++ project:

#define TRUE FALSE

Want to piss off the person reviewing your PR?

don't just return true or false use 1 == 1 for true and 1 == 2 for false.

Watch the glorious rage unfolds 🤘🤘🤘

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.

Today at work while reading legacy code:

do {
...
} while(false)

Wanna cry and laugh at the same time

Me, when read old code:
if z == true
return true
else
return false
Yeah, why not stupid fucker.

Repost from r/programmerHumor

Developers who writes something similar

if (count >= 0) { return true; }

else { return false; }

deserves a special room in hell.

someBoolean = (condition1 && condition2 ) ? true : false;

O.M.G....

if ($id != $product->getId()) {
return false;
}
return false;

What's the point?

JavaScript question of the day:
Is NaN equal to itself?

NaN === NaN

A. SyntaxError
B. False
C. True
D. NaN

I hope I can code myself like below.

me.Girlfriend = true;
me.Millionare = true;

but, the real case is

me.Girlfriend = false;
me.Millionare = false;

the sadest case is

me.Girlfriend is not defined T.T

Came across a fun one today :
Some JS dev using 'false' and 'true' instead of false and true. 😫

I have previously seen this in a production code base. The same code base included nested if statements (20+ conditions)...

If (condition == false) {
return false;
} else if (condition == true) {
return true;
}

const true = false; 🤔
(from r/ProgrammerHumor)

False Hope 😑

I can't stand when people use (SomeBoolean == false) instead of (!SomeBoolean)

Why can't Python have a switch case statement???

Also what's with the capitals in True/False?

Being told that real life experience < school degree.

You couldn't possibly be more fucking wrong.

console.log(0.47-0.01===0.46);
Output: false :/

That got me stuck for quite a while..

Learned more about floating point arithmetic and representation 😊

> 0.5 + 0.1 == 0.6
> true

> 0.1 + 0.2 == 0.3
> false

🙏🙏

Output:
true
false

Why?
This question was asked by my friend, was unanswerable.

if (obj == null == false)

Dude, what the fuck is wrong with you?

Kids use "if(condition)"
Men use "if(condition == true)"
Legends use "if((condition == false) == false)"

Took me 2hrs of my life

if (false);
{
// do sth
}

!rant

In firefox:

about:config

In "dom.webnotifications.enabled", change "true" to "false"

Website notifications are now disabled. You're welcome.

bool True = false;
bool False = true;
if (True == true)
{
False = True;
}
else
{
True = true;
False = !true;
}

if (!False == !!true && True == !false)
{
False = True;
True = (!!False)true;
}
Console.WriteLine("Banana");

The alarming rate of false news these days...

The moment you realize your time assessment was wrong again.

while(debug){
coffee++;
if(coffee == OUT){
giveUp();
debug=false;
}
}

Conference tickets are overpriced

true or false?

Do you attend any without being sponsored?

lies...

Oh Docker, why do you give me false hope...

if (variable == true)
return true;
else return false;

So, if i false just correct me to true. But if i true i will be false at the same time. But this is not false.

Thank you devRant algorithm 😂

How to test your cpu cooling system:

Open Firefox
Set option CloseOnLastTab to false
Hit CTRL W and don't let it up

Watch cpu burn.

Spent hours trying to figure out why API calls to a third party service weren't working.

Hit up their support and find out the following:

"Hi there, we can only take true and false as strings."

"Uhmm... Does it take anything apart from true or false?"

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

"Any reason why you don't take booleans if it's just true or false?"

*crickets chirping*

GFG

Ok , so True is just !False

return (this.isBad) ? true: false;

JavaScript logic:

5 + false + [] is '5'.
5 + [] + false is '5false'

Just JavaScript things:
alert(typeof NaN); //alerts 'Number' alert(NaN === NaN); //evaluates false
What else would you expect?

Your choice. Select one

Realize this took me an hour of debugging

Am I the only one who's getting more and more aggrevated about how the large youtube channels misinform and make out VPN providers (I am looking at you, Nord VPN, mostly) as the messiahs of the internet? How they protect our data that would otherwise be in incredible "danger" otherwise?

I understand they need clients, and I know most of the YT channels probably do not know better, but... This is misinformation at best, and downright false advertising at the worst...

"But HTTP-only websites still exist!" - yes, but unlike the era before Lets Encrypt, they are a minority. Most of the important webpages are encrypted.

"Someone could MITM their connection and present a fake certificate!" - And have a huge, red warning about the connection being dangerous. If at that point, the user ignores it, I say its their fault.

Seriously... I don't know if Nord gives their partners a script or not... But... I am getting super sick of them. And is the main reason why I made my own VPN at home...

True || False

JavaScript:
NaN === NaN // false
Typeof NaN === 'number' // true

boolean must be true || false || perhaps || schrödinger

if (!isset($woman))

$cry = false;

devRant taught me that most dev stereotypes are true...and false :))

My first login function

const login = (email, password) => {
If (email && password) {
return true
} else {
return false
}
}

OSC, or open sound protocol, does not have a Boolean type. instead, the Boolean true has type true and the Boolean false has type false.
what.
well.
at least the problem wasn't in my code?

didn't anyone go for the "#define true false" joke? i didn't actually see it in action, but it would be a pretty harsh one.

Today I found this jewel in a PR of a respected dev of my workplace:
if(conditions)
{
return true;
}
else
{
return false;
}

if (condition){
return true;
} else {
return false;
}

Midnight thoughts:

Why the opposite of 'true' is 'false'? why not 'eurt'?

When you search for this error during 3 hours

if (false);
{
printf("why u right ?");
}

And it was just the first lines comma

I’ll often open up my console and check if something is true and then check if the opposite is false. Thanks js

Lets play a game of spot the bug...

Too easy you say?
What if I told you that this code was written by a well paid dev over an exceptionally large period of time?

Crazy huh, but that's still nothing. The most ludicrous thing about it - is that you (like me) probably suffer from a mild case of impostor syndrome.

I just ended that suffering. The only thing worse than impostor syndrome is believing you actually know what the fuck your doing. Keep it in check but learn to love it... it's probably the reason you could spot the bug after all.

If (post.text.contains("Chuck Norris"))
{
post.visible = false;
}

Yet again

If foo():
return True
else:
return False

Agrrr!!11

Going to make a new programming language, positive# .

Where the default value of a Boolean is true instead of false.

I'm surprised management allows us to write false positive tests just to have high coverage instead of refactoring it first. Time to abandon ship.

happy debugging! ! 😈😈😈

Think of something more retarded than this:

boolean name = (getBoolean()) ? true : false;

Expect the unexpected (false) 😂

$md5 = md5_file($file_uri);
=> Returns false

Mmh...

die(is_readable($file_uri));
=> Returns false

[Mmh intensifies]

if(!is_readable($file_uri)) {
chmod($file_uri, 0777);
}

=> Chmod() returns false

GAAAAH FUCK THIS I CALL IT A DAY

This is hilarious

My man said "What should I return if the True/False field is left blank?"

WHY WOULD A BOOLEAN BE ANYTHING OTHER THAN TRUE OR FALSE???!!!

I'm gonna have an aneurysm. I shouldn't be educating people on best practices for something that's already been written about time and time again. RESTful philosophy has been documented so much, and all it takes is a quick google search, but noooo! I have to take time out of my day as if I'm a regular old stakeholder to explain that I want the exact thing that I sent in an email two weeks ago. Amazing.

2b || !2b a programmer with a bad sense of humor ?

return false;

Fucking give me an error message instead of telling me {error: "You can find more details on developer.incompetent-shits.com", success: false}

I really dislike when people don't use braces { } on if/else statements.

If(almond.harvestStatus == undefined) almond.harvestMode=false
almond.dropdown = false.

I've noticed when I talk to people I use terms like "true" and "false" a lot. Like "Dude that's totally false". "So true!"

if false? if false what? (false is just not defined, but this is the sort of shit I come across in the twig-theme-saas world, makes me angry)

Helped somebody learning Arduino (he is new to programming in general)...

I saw this at the top of his file...
I admire his effort tho...

When you debug all day, and at the end only thing that boss sees are 3 line changes in git commit.

I wrote this code last month...

def func(is_admin, user):
is_admin = is_admin or False
user = user # so pro much wow
return is_admin ^ user

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.

Spend past 2 days trying to hunt down a bug...
I forgot `0` evaluates as `false` so this statement always returned `false` if `id` was `0` >.>

PSA: negate your tests and make sure they fail!

I have what I thought was a weird and slightly paranoid habit. When I write tests sometimes just as a sanity check negate the assertion to make sure the test fails and isn't a false positive. Almost always fails as expected.

But not today! Turns out I had forgotten to wrap my equality check in an assertion so it would always pass. It freaks me out to imagine pushing a test that always passes not just because it doesn't do its job, but could also obscure a bug and trick me into thinking it works differently than it does. Broken tests are the worst!

But it pays to be paranoid.

When someone defines a Bool3 type in swift to represent true, false and undefined. Even tho swift already has Optionals as a first class feature. 😳

0.1 + 0.2 === 0.3 // false
- You know nothing JS...

!false

It's funny cause it's true!

Kids:
if(true)
{

Adults:
if(!false)
{
}

Legend:
if(!false && true)
{
}

//Girlfriend asks question
If(answer != desiredanswer){

F*cking backend guys that send empty arrays like [ null ] ...

Just found this gem:

<a href="..." onclick="if (! confirm("Are you sure you want to log out?")) return false;">Log out</a>

How to deal with legacy code when you see such thing:

if function() == !!!false

1. Ctrl+A
2. Del
3. rm -rfv /

JS be like:

0 == "0" | true
0 == [] |true

ok... so "0" equals []?

"0" == [] | FALSE

Came across a method in the code base that returns a boolean.

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#%#....

#define TRUE FALSE
//Happy debugging suckers

return in_array($boolean, [true, false]); //LOL

This is so TRUE!

Or is it FALSE?

Happy Halloween!

function isBool(input) {
return (mixed_var === true || mixed_var === false);
}

at least this crap wasn't used anywhere in the code base

#gemoftheday #wtf

Its true unless its javascript, then its false. What the fuck is this? Someone got explanation?

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
}
```

typeof NaN === typeof NaN //false

Why?

just came across the code line as below.

#define TRUE FALSE

and than......😂😂

Everybody relax! False alarm! The website wasn't down, I was still connected to the VPN.

At first it seemed harsh, but then I learned that he committed code like

if (a == b)
return true;
else
return false;

When a programmer plays truth or false, you know he/she will always say true.

Intern: "Is the keyword to allow nullable 'null=True' "
No. It's farnswaggle=False.

I’m so done of getting false errors in Visual Studio

tfw a true/false field in the database is set to char instead of boolean.

Did you hear the one about !false It's funny coz it's true.

Let me tell you a joke: !false

bool isTrue(bool val){
If(val == true){
return true;
}
else if(val == false){
return false;
}
else{
cout<<"Wrong value";
}
Function isTrue is the future ! 😂😂😂

looking at this resumee. not sure if i want to buy it 🤔

I just leave it there.

public enum FileType {
True, False
}

The worst thing is a false positive.

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.

mongpoop

this is how our upgrade from mongoose v5 to v6 went

v5: strictQuery is false by default

v6: strictQuery is true be default

^ realized this once our update went live, we are now manually migrating several hundreds of production data.

v7: strictQuery is false by default.

what!!!

allUpperCase = true
for char in rant.message:
if !isUpperCase(char):
allUpperCase = false

if allUpperCase:
rant.category = "rant"
else:
rant.category = "!rant"

True or False?

var false = true;

Failed asserting that false is true.

No shit sherlock ;/

Found this in production code.

For those who doesn’t understand Delphi:
switch (some boolean) {
case false:
// some code
default:
// some code
}

just found a build in function in a certain framework.
that function has a parameter named
"fail_silently".
func(fail_silently=False)
made me laugh.
and my laugh function was like.
laugh_func(laugh_silently=False)
😆😁

Again found myself before deadline. My excuse? I'm more productive during the deadline rush :D
How everyone else sees it: you fucked up
What do I say to myself: never again!!!
```
sleep(until_next_deadline);
goto begining_of_this_post;
```

What is NaN?
Baby, don't undefined me...
Don't null me...
No false.

True = ((True === False) == False)

End result, true is true

Why would anyone use -1 for true and 0 for false in a database.

Booleans people!!! FFS

Making migration of old project a real PITA

javaScript:

0 == "0" // true
0 // false
"0" // true

o.0

I hate complex boolean logic.

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

Just got intern to “help me” on project. Told him to install nodeJs and run ‘npm install’ inside project folder that he pulled from git.

He ended up running ‘npm install’ inside C:\Program Files (x86)\nodejs

Don’t have slightest clue how he got this idea, ... I just wanted to smash my head through window by that point. Similar shit repeated whole day long.

To all guys who write shitty code:
if (false)

I just found that when compiling for Release mode in Visual Studio the JIT compiler eliminates this:
Dead code elimination - A statement like if (false) { /.../ } gets completely eliminated.
And a lot of other similar stuff

successful = false;
return successful;

I hate complicated and out of date documentation!!!

while(!experience){

get_a_job = false;

while(!get_a_job){

It's funny it's !false

Some managers think if one woman can deliver a baby in 9 months, then two can deliver a baby in 4 and a half...

Snartsheet requires checkbox values of "true" or "false"
