While reading through the Elasticsearch (Java search engine) source code a while ago I found this gem:

I think someone should stop drinking while coding.
Some other nice lines:
int i = 0;
return j + 1000 * i;
Are these guys high?11 -

Junior dev complained about my request to remove unnecessary comments because they're too obvious. "They may be obvious to you, but not to others" he said.

return arr[0]14 -
React-Redux's connect() function inspired me to create the coolest way to add numbers in JS:
<script>
function add(num) {
return function(otherNum) {
return num + otherNum
};
};
console.log( add(2)(3) ); // Outputs 5
</script>
I didn't know you could do that. Just found it out!12 -
C is not that hard:
void (* (* f[ ]) () ) () declares f to be array of unspecified size, of pointers to functions, which return pointers to functions which return void.
By the way, I am uncomfortable with the fact that I am comfortable with this statement.

Purchase $900 laptop, it's not powerful enough so I return it and get $1,100 laptop, still not powerful enough, return it and get $1,600 laptop. Realize I have a gaming PC and don't need the laptop this powerful and I return it and repurchase the first laptop I bought with a $100 discount because it's now an opened-box, but I know for a fact that it was the one that I got in the first place and opened.

Looking into a helper class written by someone who was clearly not a master of their craft. The class deals with some string IDs...
public getIDPosition1(String id){
return id.substring(0,1);
}
So far so useless. But it gets better. What is declared immediately below the above method?
public getIDPosition2(String id){
return id.substring(1,2);
}
And below that? You guessed it:
public getIDPosition3(String id){
return id.substring(2,3);
}
This continues to position 10.... -.-7 -

Refactoring nested ifs.
I'm not a pro but I despise working with nested ifs. It's hard to debug and read.
If you cant chunk the if using method, i think you can use ifs like this:
If(){return}
If() {return}
Not like this:
If() {
If() {
If() {
}
}
}
😠😠😤🙅😢8 -

If you are programming in C++ please always return a type from a function as the function prototype return type.
I had to debug some old code that failed to return a boolean on one of its flow paths. It would work on linux in release and debug, would work on windows in debug, and fail on windows in release.
The failure was NOT straightforward at ALL. It would return exit code 3. Then if I added a debug print to the function it would segfault.
Why the hell would popping something extra off the return/call stack not crash more readily? Wth is the point of debug compile if it won't catch shit like this?8 -

Last year in my first lesson of informatics:
Me: “What does return do?”
My teacher: “If you start your program, Windows will pause and run your program. If your program is coming to the end and hits the return statement, your program will stop and Windows will run again.”
wtf

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"10 -

Here’s how my Friday night is going:
def signin
if should_not_sign_user_in?(stuff)
return redirect_to :nope
end
# signin logic
end
The guard says I shouldn’t sign the user in. It logs the details of why. I read the logs; they’re all correct. It logs the return value, which is false, and the user gets signed in anyway.
Wat.
There’s a return and a redirect there!
This is only happening on the QA server, too, so something fishy is going on.5 -

Applying Occam's razor and I might be wrong..
Hiring a candidate and job hunt, both are fucking exhaustive process.
We, as a human race, have aimed for Moon and Mars but are unable to solve the problem at hand which can save millions of hours each year reflecting in immediate cost savings.
Here's my (idealistic) solution:
A product to connect job seekers and recruiters eliminating all the shitty complexities.
LinkedIn solved it, but then hired some PMs who started chasing metrics and bloated the fuck out of the product.
Here are some features of the product I am envisioning:
1. Job seeker signs up and builds their entire profile.
2. Ability to add/remove different sections (limited choices like certifications, projects, etc.), no custom shit allowed because each will have their own shit.
3. By default accept GDPR, Gender Identity, US equality laws, Vetran, yada yada..
4. No resume needed. Profile serves as resume. Eliminate the need to build a resume in word or resume builders.
5. Easy updates and no external resume, saves the job seeker time and gives a standard structure to recruiters to scan through eliminating cognitive load.
6. Recruiters can post their jobs and have similar sections (limited categories again).
7. Add GDPR, Vetran, etc. check boxes need basis.
8. No social shit. Recruiters can see profiles of job seekers and job seekers can see jobs. Period.
9. Employee working in Google? Awesome. Will not show Google recruiters thier profile and employee such job posts.
10. No need to apply or hunt heads. System will automatch and recommend because we are fucking in AI generation and how hard it is to match keywords!!
11. Saves job seekers and recruiters a fuck ton of time hunting the best fit.
12. This system gets you the best job that fits your profile.
Yes, there are flaws in this idea.
Yes, not all use cases are covered.
Yes, shit can be improved and this is hypothetical.
But hey! Surely doable with high impact than going on Moon or Mars right now.
Start-up world has lost its way.12 -

In Java, I use dummy variables to set breakpoints and get around the return unreachable compiler/Eclipse check2
-
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. -

Not loving the implicit return statement within Scala. I like to avoid else statements to keep the level of nesting low and do early return yet Scala doesn't allow that.
(I am aware that I should flatMap that shit though in some cases I just want a simple if not foo then throw exception line. And continue with the next block until I return something.)
So you either have to create if-else-nesting beats or use pattern matching. The latter seems overly complicated for this use case (though it has its moments).
I know that I can make the return explicit yet the linter warns against that. It feels so verbose and I currently do not see any benefits and would argue that the code becomes both harder to read and maintain.3 -
That's gonna be a quick rant about Golang.
Anyone else here frustrated by the fact that you can inline assignment in the if statement, but can't inline the if-else itself?
You can do:
if thing := hey.getThatThing(); thing == theThing {
return 'this'
} else {
return 'that'
}
But can't do:
return 'this' if hey.getTheThing() == theThing else 'that'

Questions that are bothering me:
When a function that returns void returns, is any value from the stack frame copied into the register?
Is the return address in the stack frame even allocated, or is it nullptr?
Could a void function theoretically return a value if you hacked one into the frame?
Does the register even know to expect a value from a void function? If so, where is the logic for this and what is difference between a void and non-void function return at the stack frame & register level?
Any good books on this stuff?2 -
Do you guys return 200 when a search function in your API returns a not found and you attach a response in the object saying "success: false", or do you return 404? I'm confused. Thanks.

5. } catch(e) {
6. return null;
7. }
8. return data.someParam;
9. }
10.}
Nothing like bad practice in above code but I always feel that the line 4 should be replaced by below.
4. var result = JSON.parse(data);
and then use result variable to get data one is looking for, like below
8. return result ? result.someParam : null;
Your thoughts?3 -

javascript/typescript people
getNumberFromCalculation(number a, number b)
better to throw new RangeError when you get a bad number combo that doesn't make sense
or return a RangeError ? (if that's a thing) and then have to check if you return the calculated return number value or an Error every time17 -
This will never clash:
static createGuid() {

return Math.floor((1 + Math.random()) * 0x10000)
.toString(16)
.substring(1);
}
return s4() + s4() + s4() + s4(); // Example => 'e014026082e6237b'

Why the fuck does B&R's find in string function return 0 when the search string was not found? The return type is not even unsigned?!5

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_VALUE14 -
So I've spent some time learning a little about the halting problem, and it's quite fascinating. I tried to simplify it down to these few functions. What do you guys think? Obviously, psuedo-code, so don't get too caught up on the syntax 😆
The Halting Problem:
public String doesItHalt(Callable function){
...
if (...){
return "Yes"
} else {
return "No"
}
}
public int someFunctionFooThatHalts(){
...
}
public int someFunctionFooThatDoesNotHalt(){
...
}
public String inverseAnswer(value){
if (value == "Yes"){
return "No"
}
if (value == "No"){
return "Yes"
}
}
public String inverseHalts(Callable function){
return inverseAnswer(doesItHalt(function))
}
————————————————————————————
$ doesItHalt(someFunctionFooThatHalts)
Yes
$ doesItHalt(someFunctionFooThatDoesNotHalt)
No
$ inverseHalts(someFunctionFooThatHalts)
No
$ inverseHalts(someFunctionFooThatDoesNotHalt)
Yes
$ doesItHalt(inverseHalts(doesItHalt))

Interview Question:
Are there other options to make this go any shorter?
if (john == doe == max == paul == stella == false)
return "Not Okay";
return "Okay";
I did...
return (!john && !doe && !max && !paul && !stella) ? "Not Okay" : "Okay";
That was the shortest i could come up with... Maybe there is something shorter, dunno.6 -
Is it normal that my lead developer insists that if(x){return A} else {return B} must be changed to if (x){return A} return B, and a variable must be renamed from requestFn to requestFunc because the former is confusing?12

I feel like I didn't do this right and I'm a tad confused as to what they mean when they say that the function should look like this when you call it:
let line = openingLine(verb: "row", noun: "boat")
Is my solution correct?

I pass the day writing a script to encapsulate the migration of the old csproj to the new format. But, when the open source app returns an error of migrating the script continue. I check the return code and when it's an error, it's return 0.
After many tries, I return to my house and start looking at the open source code for understand what's happening and try to correct it.
OMFG, I cannot change the code to return an `int` instead of void. The method is in the public area of the code.
I very happy that this app, it's open source, so I can do my own version for my need.1 -
So is the difference between inheritance and composition is that of a fridge and iceman?
class Man {
fun greet(){return "hi"}
}
class IceMan extends Man{
override fun greet(){return "hi i am iceman"}
fun getIce(){return "ice"*Random.nextInt()}
}
class Fridge{
private Man manAi;
private String s = "ice";
fun greet(){return manAi.greet()}
fun getIce(){return s*Random.nextInt()}
}
}
=========
Basically , in first case, a class is getting features by inheriting from parent while in another case, a class is getting features by internally having objects of other classes that could provide those features?6 -
