Interviewer: "Using this 2D array and calculate.."
Me: "This input isn't a 2D array though. Do you want me to parse or construct a 2D array then.."
"It is a 2D array."
"Uh.. ok..and if it's not what if we.."
"Look my notes say you must use this input, and treat it as a 2D Array"
"What if I wrote a function for a 2D array similar to this input, but actually a 2D array"
"You must use only the input provided"
Me: does rain dance code for 20 minutes.
Interviewer: "hmm, maybe it wasn't a 2D Array. I like your efforts but that's all the time we have today."
I promise I can code, sometimes. It does help to have correct questions to give correct answers.1 -

... so... maybe not that much of a thing, but i think it is:
a gal (27 years old) i started teaching programming two weeks ago, who had literally no previous experience with programming, algoritmization nor c#...
... just now, after 3 lessons of 6 hours altogether, and after yesterday when i explained to her what arrays are and reminded her what loops do...
... invented bubble sort. on her own. no googling. on paper. no "trial and error code typing and running".
i'm actually pretty proud of her :)
... putting the algo concept into actual code will still be a bit of a struggle, but yeah, hell, can't help thinking that she's actually pretty smart :)
(p. s. fist lesson was i drew uml of a fibonacci algo and forced her to understand what it does, second lesson was i explained the minimum required c# syntax for her to be able to implement it and forced her to write it (with as little help as i could), third lesson was the concept of array and "okay, now here's array of numbers, make a function that will sort them")
looking forward to what will happen when i explain recursion and nudge her towards quicksort O:-)8 -
Found a bug which occures because a certain array has not the right order. At the place where it gets relevant, I found a comment written by myself ages ago 'sorting the array is not necessary because blabla'
... NICE TRY PAST SELF, BUT YOU WHERE JUST FUCKING WRONG.3 -
Come on guys, use those JSON schemas properly. The number of times I see people going "err, few strings here, any other properties ok, no properties required, job done." Dahhh, that's pointless. Lock that bloody thing down as much as you possibly can.
I mean, the damn things can be used to fail fast whenever you misspell properties, miss required properties, format dates wrong - heck, even when you want to validate the set format of an array - and then libraries will throw back an error to your client (or logs if you're just on backend) and tell you *exactly what's wrong.* It's immensely powerful, and all you have to do is craft a decent schema to get it for free.
If I see one more person trying to validate their JSON manually in 500 lines of buggy code and throwing ambiguous error messages when it could have been trivially handled by a schema, I'm going to scream.18 -
I am embrassed.. :(
Situation was..
It was 3-4 months ago I written the process but now client was saying it is not working so I just need to update value in array..
I spent 2-3 hours everything was good..
only in the statement where I am assigning the value is not working.
I was like dude wtf call your senior why its not working .. everything is correct.. then suddenly my eyes catch the rubbish thing I did..
this is what I used mistakenly for assignment "=="
:( and I was looking at statement from 1-2 hour.. it just wasted my time5 -
Company A (mine) is building a site for company B, company B employs company C to manage their inventory database, company C exports inventory as JSON to company A, company C says, this field (SKUs) will be an object (skus = {...}) when it only has 1 value, but an array (skus = [{}, {}, ...]) when there are multiple SKUs, company A (me) tells company B to tell company C to ensure it's always an array.... company B is scared of company C and company A (me) is always cleaning up company C's shit6

Do I have just a bad version of ecma script or is this some stupid shit in JS in general? I want each sub array to be separate entities, not that same one for all. I assume the fill in just putting the same list in all of them? I honestly don't care I guess, replacing a sublist is fine too. Rather than editing each element separately. Saves ram in long run.
let arr = Array(5).fill(Array(1,2))
console.log(arr)
arr[0][0] = 3
console.log(arr)
[[1,2],[1,2],[1,2],[1,2],[1,2]]
[[3,2],[3,2],[3,2],[3,2],[3,2]]
Congratulations, you are my dev duck today.19 -
So I'm re-writing my tokenizer. I've just installed ElementaryOS a couple of hours ago and re-wrote it on Linux.
So far so good;
(5) ['->', 'out', 'with', 'Hello, World.', ';']
0: "->"
1: "out"
2: "with"
3: "Hello, World."
4: ";"
length: 5
[[Prototype]]: Array(0)
I wish we could highlight code on devRant. Such a simple thing would make this site look way better and more readable.
Everyone shunned my idea because it's for "ranting" but I always see people writing code anyway. You might as well add the feature.12 -
My two main grudges against Typescript:
1) Union types can't be passed as arguments if there is a variant for every element of the union
2) No tuple polymorphism, i.e. [T, U] isn't assignable to [T]. This is not a mistake because the length of the arrays differs and therefore they may be interpreted in a different way, but IMO there should be a tuple type which is actually an array but length is unavailable and it supports polymorphism. This sounds stupid, but since function parameter lists work well with tuples it would actually enable a lot of functional tricks that are currently inaccessible.7 -
Terraform + helm-chart ... I really ned a break. Who the fuck invented this shit.
The HCL format sucks
The documentation sucks
The dev tools suck
The debug output sucks
But I'm ok with that, I can manage.
But today really it shot the bird ... I can't have a fucking comma in a string? Because idk why the fuck helm-release tries to parse that fucking string and wants to make an array or whatever out of it? Why, you fucking abomination?
Something in the docs? Nah, who reads them anyway.
Because you know it's totally not strange that a string is analyse and oh wait there's a comma in it, the dev surely wants me to make an array out of it, because you know ...
So now I have to escape my fucking comma to prevent it to parse my fucking string. I just want to have a fucking string you hideous monstrosity ....1 -
My programming class kinda sucked. Here's why.
1. They taught C++. To students who had never seen a line of code in their lives. The language with 90+ keywords.
2. The teacher. We had to use switch statements to do something. It took around 300 loc. I used an array and shortened it to 5. He took some points away for not doing it correct. IT LITERALLY WORKS THE SAME AND IS SHORTER. This was not the first time I had shortened something/made it more readable and been docked points on the assignment.
3. Commenting. He told us to comment as much as possible, which is not correct. Comment what needs commenting. Not everything.
4. The compiler. We worked on windows with an online compiler. He decided teaching us to set up a compiler was too hard. We used onlinegdb, which isn't inherently bad. However, onlinegdb is based on Linux. He compiled our programs with a windows compiler.
Maybe these are just problems because I've programmed before that, but I still think they are red flags. What do you think?4 -
I rolled out a feature in one of my previous organizations. It looked awesome. I couldn’t wait to receive all the praises and appreciations but instead was bombarded with bugs and issues. Well, I tested the feature on chrome but little did I know that the users used IE and safari. This is where polyfills in javascript step in. Here I've assembled a list of some important polyfills. Do read it and let me know your opinions.

4 hours wasted due to a rather strange "scope poisoning" bug... it was really fucking strange.
Had to move the 5 lines of code, above where the error happened, to a private function.
The 5 lines just called an XLSX library which read a given file and returned an array. I don't know how but the thing somehow messed with my Soap client call one line below. The culprit must have been some IO resource handle which didn't get destroyed when in the same scope due to persisting object references..1
