I have an array of 1037 records. The soap service only accepts 100 at a time. So, I write code to send an array of 100 records at a time to the soap service in a loop and get a response back of, "The maximum number (100) of records allowed for this operation has been exceeded." Well, I'll try 99 records then. Nope same error. I'll try 50 records, nope I'll just bang my head on the desk now since the documentation and error say it is a record limit of 100. 😠
Look at my code again. I was grabbing 100 records out of the array of 1037 records and storing it in a new array, but I was sending the original array with 1037 records instead of the temporary array in the loop. 😢 I'm going to bed.7 -
My thoughts on programming:
As a child:
It is 100% magic
As a developer:
It is 65% if/else statements, 34% iterating an array, 1% actual amazing and unique code15 -
How language creators choose the function to get the size of an array..
I mean, the life could be more simple, this is just an example.

Did this on my first programming exam.
int index = 0
int value = 0
try {
while true {
value += array[index]
index++
}
} catch NullPointerException {
System.out.print("Sum: " + value)
}
The task was to add together all numbers in an array.
I somehow aced the exam, but got called in to teachers office this is not the way to use exceptions.7 -

People on Stack Overflow are SUCH FUCKING ASSHOLES
"You didn't show us where you declared this unimportant array, please review this article for how to ask questions"
My question doesn't concern the array, my question concerns how the system works, all code I provided was only for clarity. Read my fucking question you arrogant asshole. You have lots of points, fine, go tell your mother, but you assume I don't know how to ask a question which you clearly did not read.10 -

After working as a developer for 4-5 years I finally took up school again.
The teacher at our first programming course insisted that we named all our variables in our locale language (swedish) and always started arrays at index 1.18 -
My teacher told us, that the array size in C is useless, becouse the array is dynamic and can be bigger or smaller everytime you want.. Happy overriding..13

It's not that I hate PHP, I just hate the lack of consistency in standard function naming and parameter order, nonsensical attribute access, nearly-meaningless comparison operators, reference handling, case (in)sensitivities, and more!
I mean, look at these functions:
strtoupper(...)
bin2hex(...)
strtolower(...)
And look at THESE FUNCTIONS:
array_search($needle, $haystack)
strpos($haystack, $needle)
array_filter($array, $callable)
array_map($callback, $array)
array_walk($array, $callable)
And let me jUST USE SOME ATTRIBUTES:
$object->attr = "No dollar sign...";
Class::$attr = "GOD WHY";
HOW ABOUT SOME COMPARISONS:
(NULL == 0) // true
(NULL < -1) // ALSO true
Functions AREN'T CASE SENSITIVE (at least variables are).
Wanna dereference? TOO BAD, YOU'LL HAVE TO GET OUT THE TNT.
Alright, yeah, I hate PHP.18 -
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 -
I had to open the desktop app to write this because I could never write a rant this long on the app.
This will be a well-informed rebuttal to the "arrays start at 1 in Lua" complaint. If you have ever said or thought that, I guarantee you will learn a lot from this rant and probably enjoy it quite a bit as well.
Just a tiny bit of background information on me: I have a very intimate understanding of Lua and its c API. I have used this language for years and love it dearly.
[START RANT]
"arrays start at 1 in Lua" is factually incorrect because Lua does not have arrays. From their documentation, section 11.1 ("Arrays"), "We implement arrays in Lua simply by indexing tables with integers."
From chapter 2 of the Lua docs, we know there are only 8 types of data in Lua: nil, boolean, number, string, userdata, function, thread, and table
The only unfamiliar thing here might be userdata. "A userdatum offers a raw memory area with no predefined operations in Lua" (section 26.1). Essentially, it's for the API to interact with Lua scripts. The point is, this isn't a fancy term for array.
The misinformation comes from the table type. Let's first explore, at a low level, what an array is. An array, in programming, is a collection of data items all in a line in memory (The OS may not actually put them in a line, but they act as if they are). In most syntaxes, you access an array element similar to:
array[index]
Let's look at c, so we have some solid reference. "array" would be the name of the array, but what it really does is keep track of the starting location in memory of the array. Memory in computers acts like a number. In a very basic sense, the first sector of your RAM is memory location (referred to as an address) 0. "array" would be, for example, address 543745. This is where your data starts. Arrays can only be made up of one type, this is so that each element in that array is EXACTLY the same size. So, this is how indexing an array works. If you know where your array starts, and you know how large each element is, you can find the 6th element by starting at the start of they array and adding 6 times the size of the data in that array.
Tables are incredibly different. The elements of a table are NOT in a line in memory; they're all over the place depending on when you created them (and a lot of other things). Therefore, an array-style index is useless, because you cannot apply the above formula. In the case of a table, you need to perform a lookup: search through all of the elements in the table to find the right one. In Lua, you can do:
a = {1, 5, 9};
a["hello_world"] = "whatever";
a is a table with the length of 4 (the 4th element is "hello_world" with value "whatever"), but a[4] is nil because even though there are 4 items in the table, it looks for something "named" 4, not the 4th element of the table.
This is the difference between indexing and lookups. But you may say,
"Algo! If I do this:
a = {"first", "second", "third"};
print(a[1]);
...then "first" appears in my console!"
Yes, that's correct, in terms of computer science. Lua, because it is a nice language, makes keys in tables optional by automatically giving them an integer value key. This starts at 1. Why? Lets look at that formula for arrays again:
Given array "arr", size of data type "sz", and index "i", find the desired element ("el"):
el = arr + (sz * i)
This NEEDS to start at 0 and not 1 because otherwise, "sz" would always be added to the start address of the array and the first element would ALWAYS be skipped. But in tables, this is not the case, because tables do not have a defined data type size, and this formula is never used. This is why actual arrays are incredibly performant no matter the size, and the larger a table gets, the slower it is.
That felt good to get off my chest. Yes, Lua could start the auto-key at 0, but that might confuse people into thinking tables are arrays... well, I guess there's no avoiding that either way.13 -
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.

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 -
When you see a Java devotee using Python and they're doing something like this:
array = [1, 2, 3, 4]
for n in range(0,len(array)):
print(array[n])
At least I get to tell them "hey it doesn't have to be so hard just do it like this:"
array = [1, 2, 3, 4]
for n in array:
print(n)12 -

Client's API returns a very weird response that changes its structure depending on its content.
When a array field has more than 1 children it returns:
{
"field" : [
{ "name1" : "value1"},
{ "name2" : "value2"}
]
}
So far so good. However, the fuckery happens when it has 1 children:
{
"field" : { "name1" : "value1"}
}
WTF! So the client API can return either a JSON object or an array and we cant trust the specs they gave us.4 -

Php array methods, all of them, or should i say hash methods
They should fix them. I mean they should fix placing of callback and subject params, because.
I mean
array_filter(array, callback)
array_map(callback, array)
Or they should make array a object like js4 -
my previous boss once told me [ ] array initializing syntax will be depricated in php 7 (few years ago) so i should only use array() instead.
couple months back after i got used to always using the latter i found out the first was never depricated but he just prefered how array() looks6 -

PHP ist one of the languages I use regularly, but not the main language.
Anyhow, passing an array to a function will create a Copy of the array unless you specifically choose to Pass the reference.
That's seriously fucked up. What other language does that?! Coming from C, Java, Python to PHP I was not prepared to expect shit like that.

PHP arrays.
The built-in array is also an hashmap. Actually, it's always a hashmap, but you can append to it without specifying indexes and PHP will use consecutive integers. Its performance characteristics? Who knows. Oh, and only strings, ints and null are valid keys.
What's the iteration order for arrays if you use them as hashmaps (string keys)? Well, they have their internal order. So it's actually an ordered hashmap that's being called an array. And you can produce an array which has only integer keys starting with 0, but with non-sequential internal (iteration) order.
This array weirdness has some non-trivial implications. `json_encode` (serializes argument to JSON) assumes an array corresponds to a JSON array if its keys are consecutive integers in increasing order starting with 0, otherwise the array becomes a JSON object. `array_filter` (filters arrays/hashmaps using callback predicate) preserves keys, so it will punch holes in the int key sequence if non-last items are removed, thus turning arrays into hashmaps and changing your JSON structure if you forget to discard keys before serialization.
You may wonder how JSON deserialization works, then? There's a special class for deserialized JSON objects, `stdClass`. It's basically a hashmap too, but it's an object, not an array, and all functions that would normally accept arrays won't work with it. So basically its only use is JSON (de)serialization. You can even cast arrays to objects, producing `stdClass`.
Bonus PHP trivia:
Many functions return nonsensical values. `preg_match`, the regex matching function, returns 1 for success, 0 for no matches and false for malformed regular expression. PHP supports exceptions, so it could just throw one on errors. It would even make more sense to return true, false and null for these three cases. But no, 1, 0 and false. And actual matches are returned by output arg.
`array_walk_recursive`, a function supposed to recursively apply callback to each element of an array. That's what docs say. It actually applies it to leafs only. It will also silently accept object instead of array and "walk" it, but without recursing into deeper objects.
Runtime type enforcing is supported for function arguments and returned values. You can use scalar types, classes, array, null and a few special keywords. There's also a `mixed` keyword, which is used in docs and means "anything". It's syntactically valid, the parser will accept it, but it matches no values in runtime. Calling such function will always cause a runtime error.
Strings can be indexed with negative integers. Arrays can't.
ReflectionClass::newInstanceWithoutConstructor: "Creates a new class instance without invoking the constructor". This one needs no commentary.
`array_map` is pretty self-explanatory if you call it with a callback and an array. Or if you provide more arrays of equal length via varargs, callback will be called with more arguments, one from each array. Makes sense so far. Now, you can also call `array_map` with null instead of callback. In that case it treats provided arrays as rows of a matrix and returns that matrix, transposed.5 -
You know what just gets to me about garbage-collected languages like c# and Java? Fucking dynamic memory allocation (seemingly) on the stack. Like it's so bizzare to me.
"Hey, c#, can I have an array of 256 integers during run-time?"
"Ya sure no prob"
"What happens when the array falls out of scope"
"I gotchu fam lol"8 -
So c# has its own system.collections.list and system.collections.generics.list<type> classes. And this guy wrote his own list (no generics) using an object[] array which always had same size.4

There was a computer programming teacher in my 1st semester who taught C. He used to have this conventional way of teaching C like other Engineering subjects which was going to more theories before writing actual codes.
These are the conversations with him.
(First day, a guy asks him some questions.)
Guy: Sir, why do we need to learn C? There are other languages used extensively for other tasks like python,etc. Why bother with this boring C?
Teacher: C is used to learn other languages. After learning C, you can easily learn other languages.
Guy: Sir, where is C's application? Where is it used?
Teacher: It is used in academics to lay foundation for students to learn other languages which are used to build softwares.
(Fucking Hilarious)
(A month after he was asking some questions to students.)
Teacher: What is an array? What is an array-name?
Student 1: Array, is this collection of data that can be stored in a single type.
Teacher: Then what is an array-name?
Student 1: I don't know.
Teacher: (angrily) Array-name is a definition itself.
(We were supposed to answer that. It was a standard definition.)

after beginning to learn numpy , i believe these packages were really created by some clown of a circus xD.
Everything is sooooo entertaining!!!
i learned java 3 years ago, but today if i had to crap out some crazy java or c++ expert , i would tell him about numpy's arrays...
Like , "hey dude python has this cool data structure in the numpy library called arrays, which can hold any datatypes in a kind of arraylist like fashion, and you can convert them from 1 dimensional to 1000 dimensional in just 1 line , and also do you know we can select any column with just array[position]? and even this position does not needs to be an integer, you can use a list , like array[[1,2,3]] will give you elements at array[1],array[2],array[3], and...."

You guys remember that awful Java class that I'm taking at uni? Mentioned in this rant here: (https://devrant.com/rants/1461472/...).
Well we had an assignment to make a program that accepted any amount of numbers from a user and add the unique ones to an array (so if 2 was already entered, it would not be added to the array a second time), and then print the array out backwards. Simple as fuck right?
I checked my grade from the assignment I turned in and see that I only received 10 out of 50 points. Why?
"Program compiles and works with expected output. Partial credit for using ArrayList instead of array".
Uhm.. Partial credit is 10 out of 50?? And what the hell? Yeah okay let me go make this stupid program that involves an array with an unknown length and see how fucking perfect it works out for me.
Fuck you for docking my grade because I made a program that was sensible.

I can’t say it’s the most painful but it’s one of my recent painful lessons.
So I’m learning C and in my project I was trying to make a copy of a 2D array and I kept getting seg faults up the ass every time I tried to allocate one of the inner arrays and after a long day of debugging I realized that I was trying to allocate memory within an array that doesn’t exist so I had to create the first array then allocate memory for each inner array after.4 -

There is a mAtHeMaTicAl pRoOf 🤡 that a comparison-based sorting algorithm cannot get more efficient than O(n*log n). That's bullshit. Radix sort et al. — granted, they're not comparison-based.
But there is one comparison-based algorithm that can sort an array in O(n). It's called Stalin sort.
It traverses the array and deletes every item that doesn't appear in order. Boom, problem solved — the array is sorted in O(n), at the expense of losing (most of the) elements.
This is the perfect metaphor of Stalin's politics.4 -

Linux software RAID and LVM are pretty powerful.
Bought a new server case for my home file server / VM host. 3U with 16 hotswap bays. Had 2x software RAID1 mirrors already with everything on them. Inserted 2 new disks with system running. Created new RAID10 array using these, with their mirrors as "missing".
Created new physical volume. Extended volume group into it, then used pvmove to transfer every logical volume across. Shrunk volume group to no longer use the old RAID1 array, disassembled that array, added its disks to the new array... Now just waiting for the mirror disks to sync up.
All this, with the system and several VMs still running.
And with a backup, of course ;)3 -

Laravels error reporting is sometimes fucking useless. Yesterday it wrote into the logs "class foo doesn't exist". I triple checked the including of this class. Checked the namespaces. Checked the classnames. Everything was ok.

Helping out a friend how to code, and he said:
"Can't we just use a string? An array is just like a string anyway."
We were looking at some setting types in Visual Studio. -
This way of converting "string" to "s" (for example)
0) program reads the whole buffer, stores it as an array of instructions
1) program reverses the order of the instructions
2) parser makes standard token from an instruction ("asd" -> ASD)
3) parser2 assigns operands to instruction
4) parser 3 makes string from instruction token ?????
5) parser fucking 4 makeS A MUTABLE STRING INSTRUCTION
6) PARSER FIVE SUBSTITUES OPERANDS
7) AND THEN CUTS IT TO A REVERSED ARRAY OF COMMANDS
8) AND PUSHES IT UNTO THE STACK

messy backend API. root level payload object has a property that is being repeated in a property that takes an array of objects where this same property exists in each object in this array.
why do people work in a messy manner like this? why pass the same data twice in the exact same request?

React's `useEffect()` won't fire if you have someone in your team wrote a hook that maintain a state of an array, mutates the array, empties it, and then set it back to the state.
https://codesandbox.io/s/...
Reported it, ticket closed without asking, told should avoid mutating the object stored in useState.
Isn't it bluntly obvious that if someone spent hours to spot the line in hundreds of lines of code, which actually caused the problem and reduce the whole piece of turds into some understandable minimal reproducible example means they must of course for sure know that by avoiding mutating the array it will fix the bloody issue?
Isn't that bluntly obvious they are trying to say that there is a bigger issue behind those twisted wires?9 -

PHP is such an absolute shit.
`array_map` takes function first param, array second param
`array_walk`, which is similar for associate arrays, takes array first param, function second param
and at the same time, the function of `array_walk` takes parameters in `value, key` order
what the crazy fuck this is.2 -

Oh Shit! Here we go again!
print(request_permissions)
>> [ ]
if request_permissions:
//some if shit
else:
raise 404
It was supposed to raise 404 for empty array, but continue to exit if.
Me: What the fuck?
**printing request POST data**
**empty, nothing wrong here**
**double checked print statement output**
** still printing [ ] **
**restart server and again checking print statement**
**still same**
Getting mad over myself, for failing to debug simple if else.
Wait....
print(type(request_permissions))
>> <class 'str'>
Me: What the actual fuck??

I had to solve some issues regarding comments on a Wordpress site.
I noticed some interesting code that an old developer had left behind.
It was an array of swearwords, and an if statement that checked if words in a comment existed in that array of swear words.
It was written in Javascript, everyone; including the customer could see the array of nasty words...3 -
Devs who use the array map method for purposes other than generating a new array, and who use an empty return statement to satisfy the linter, should receive a slap in the face. A gentle one, but a slap nonetheless3

ARRAY LIKE OBJECTS
Long story short, i am fiddling a bit around with javascripts, a json object a php script created and encountered "array-like" objects. I tried to use .forEach and discovered it doesnt work on those.
Easy easy, there is always Array.from()..just..it doesnt work, well it does work for one subset called ['data'] which contains the actual rows i generate a table from, but for the ['meta'] part of the json object it just returns a length 0 object..me no understanderino
at least something cheered me up when researching, it was an article with the quote: "Finally, the spread operator. It’s a fantastic way to convert Array-like objects into honest-to-God arrays."
I like honest-to-God arrays..or in my case honest to Fortuna..doesnt solve my problem though2 -

Deciding to make the website I'm working on a one pager with calls to API.
Why did I decide to make such an extensive API. 😅

- create (sub)menu categories
- create items (install/test/image)
image endpoint:
- create image (of machines in array)
- restore image (of machines in array)
install endpoint
- install machines (Windows/Linux)
test endpoint
- auto-test (array of machines)
- test (array of machines, test)
Then the machine endpoint:
- if action in table then do action3 -

I have a PHP related question.
I noticed a few frameworks make use of this structure of code and it makes absolutely no sense to me. There would be a PHP file, and the contents of the file would be as follows:
<?php
return [
‘a’ => ‘b’
];
My only understanding is that this is an array/object but I have no idea how these values would even be accessed.
Like, there is no array variable, how can a php file simply return something into a void? There isn’t a function or variable to catch that array.
How does this even work?23 -

I've got a question about PHP arrays as I try to update my coding skills.
The problem I'm trying to solve is converting one vendor's CSV format to another vendor's format for a daily processing job.
I have a multi-row CSV file (number of rows changes daily but fields (15) do not). My PHP converts it to an array with fgetcsv so I can then copy its rows and data to a different blank target array with the same number of rows as the source array, but a different field order and number of fields (55) than the source array.
From here I will apply certain conditional business rules to copy data, field-by-field, from the source array fields to the target array fields, then output the target array to a CSV.
I'm stuck trying to figure out how to create (initialize) that target array so that it exists when I loop through the source array and copy values over to the target array.
Can anyone nudge me in the right direction on how to dynamically (loop?) create that multi-dimensional target array of n rows and 55 columns? I looked at http://w3schools.com/php/... for guidance but can't figure out how to structure the loop to make just one array of n rows and 55 columns, and not "n" arrays of n rows and 55 columns.5 -
So I have an array of length 20 which stores a 64 bit decimal number by digits. The starting address is let's say array64. When I am trying to build up my number in ECX:EBX, I am using EDX as the iterator to access the individual elements of the array (I am loading them into AL)
.LOOP:
....
MOV AL, [array64+EDX]
INC EDX
....
JMP .LOOP
The problem is: somehow EDX cannot get higher than 10, so the program just stops and waits for input, when I try to work with a 12 digit number...
This module is outside the main function, and I thought about some Far Pointer problems, but all of my ideas just failed...

!rant Spent days reading Unicode docs, trying to make sense of what codepoints were included in every Unicode property escape in JavaScript and awk’ing the heck out of the different text files associated with them.
Then at around midnight the other night, it came to me. I was an idiot.
I could literally just create an array including every Unicode codepoint and write a program to iterate through the array and test if it matched against a Unicode property escape.
Unicode array: https://gist.github.com/AmyShackles...
Program to compare against Unicode property escape: https://gist.github.com/AmyShackles...
So. Much. Easier.

Project was based on Ionic3 with angular and SCSS.
Ionic has an SCSS array with colours that generates countless CSS classes for each combination of color-component.
Smh I managed to reduce the amount of colours in that array and reduced the overall size of the final CSS by 48% (from ~8MB to 4.1MB)
Of course the overall app had no performance increase BC the problem is the main.js file which is about 12MB with no lazy load3 -

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 -

in BASH you cannot reassign associative arrays (i.e. string:string maps) to other variables.
If you have created an array as variable "arr", doing
```
declare -A arr2
arr2=${arr}
```
will not give you var2 as a usable assoc array. It will kind of transform it into an indexed array
In fact working with assoc arrays in shell is a bitch.3 -
In Go, one symbol is called a rune. A string is a string, but when I try to manipulate it, it turns into an array of bytes, not an array of runes. I then have to deal with this crap.

In android 7.1, I've seen a lot of conflicting reports about crypto security.
If I do something like the following in the default android 7.1 browser...

How secure would the resulting numbers be overall? I'm asking because I've seen a lot of articles talking about it, but they never specifically mention the default 7.1 android *browser* and what or how it obtains secure random numbers. They only ever talk about the api, sdk, and developers working in java.4 -

I spent 2-3 days on debugging code written in assembly script. Apparently, you need to initialise an array using new method otherwise it re-uses the previous array from the same scope and it has created infinitely large array. Just wtf.

Running the environment locally wasn't an option because well it doesn't fucking work locally. So, I have to forcibly test on CI and they have created a site that can show you logs because you can't access or query data directly from server and while debugging you try to log something it randomly works sometimes and sometimes you get output from god knows which deployment.

You have an array of objects with a startIndex and endIndex representing their position in a string & you want to end up with a nested structure to represent their relation in the string (i.e., A is from 1 to 10, B from 3 to 5, C from 4 to 5, D from 7 to 9). How would you do it?
Input array looks like: https://gist.github.com/AmyShackles...
Desired output looks like: https://gist.github.com/AmyShackles...
(Though what I really have to start with is an object whose keys are the start index and whose values are values of each element in the above input array, so if you can think of a way to morph it without needing to turn it into an array first that’d also be cool)
