Any language that requires functions be coupled to a "class" is a meme, face it.

How do i learn EVERYTHING that matters about a certain language?

>>56413789
The old thread is not over the bump limit you fucking asshat niggerian.

>>56413992
what's this _meme_?

>>56413992

There's no requirement for that. C# has structs which can just be composite data types.

The only thing it really doesn't have is free functions, which I don't like.

>>56413924
Yeah, C# and Java cucks should just end themselves.

>>56414027

Some people use ALL CAPS on certain words to convey a certain tone, and others use underscores. Mostly because they are autistic.

>>56414033
There is literally no reason to not just allow free floating functions. Otherwise you wind up contorting your architecture in ways that don't really make sense when you have a function that needs to be shared between several different classes, but doesn't require any state of its own.

>>56414058
>There is literally no reason to not just allow free floating functions.

Oh never mind just actually looked at your code properly.

Not really no, because you've gotta deal with the offset nuance.

I mean you could do the dictionary thing and use `DayOfYear` and then just quickly work out what days of the year it flips over to the next star sign and use that instead.

It'd take you a bit of time to work out all the days exactly, but it'd be a lot more compact.

you don't need a dictionary just a small array of day numbers, then you find the relevant array index by comparing the input day number with the numbers in the array, then you look up the star sign string in another array

In general, if you have a programming problem, you can solve it with monads.

I'll gladly kiss you, anon. C'mere for a smooch.

If your language can implement

traverse_ :: (Foldable t, Applicative f) => (a -> f b) -> t a -> f ()

, then it may be a useful language.

Scala has the potential to be a useful language: https://github.com/scalaz/scalaz/blob/series/7.3.x/core/src/main/scala/scalaz/Foldable.scala#L77

Java, C#, F#, and Rust do not have the potential to be useful languages.

Haxe is the future of development. It's a high-level language with great cross-platform support and an excellent set of support contracts to ensure any start-ups get the support they need to transition to the Haxe ecosystem.

I highly suggest giving the language a shot.

>>56417154
main reason I'm using xdotool is because I don't know how to handle text so I grep the html file for the lines containing the image urls then use a vim macro to delete all the unneeded stuff. I also don't know web stuff so I'm downloading the html sources by hand and then running the script to get the image urls and plugging them into wget

>>56417222
there's probably a way to do it for parsing the html files but I don't think there's a way to cycle through the webpages without xdotool since the url's have unique id's instead of an order.

Wrapping everything in a class guarantees:

You won't make global variables.
This also simplifies the parser.

>>56417498
No, the first one. It evaluates each argument before calling for_each, and in doing so selects one lambda over another once, and for_each just calls that lambda over and over, as opposed to checking toggle at each iteration.

This is not at all uncommon. I got a job where some of the "senior" developers can't even setup Eclipse, don't know how to checkout from Subversion, and are generally helpless with everything. It's a bit infuriating that they make more money than me. I stay because it's given me job security. I show up an hour late, leave an hour early, take long lunch breaks and smoke breaks. All I have to do is not be retarded for a few hours and everyone thinks I'm a miracle worker.

However, I also have a reputation for being "dangerous" to work with because I've outclassed so many people. The first guy I worked with was fired after I started doing his job better than him and more. The person I'm working with now is terrified because the same thing is happening. She's basically been on cruise control for the last 5 years doing 2-3 hours of worth of work in a given week, but because nobody really understands what she does, nobody could judge how productive she is. I'm actually amazed by how little she knows about the project she has supposedly been working with all this time. She asks me super basic questions all the time and is generally incapable of all but the simplest changes. Management even told me that if budgets need to be cut again, she's the first on the list to go.

This isn't because I'm some super genius, awesome programmer guru. No. It's just that so many people in our industry are head-up-their-ass retarded that even someone who just finished CS101 could do a better job.

No. They make more money because they've been with the company longer. Pay is based entirely on years of service. I've been there for two years. My frequent breaks are tolerated though because I get way more done than anyone else.

In fact, my role in the company has changed as a result. I was originally hired to work on a specific application. Now, I basically jump from project to project to be the guy who puts out fires caused by Chads and Patels. It's nice though because I get some say in what I work on. For example, there is one team that is trying to rewrite a large application and the lead engineer didn't like me pointing out all the mistakes. So every change I made got reverted and I was basically given a stack of Jira tickets and had to submit my work to be reviewed. That's how a lot of teams work, yes, but if the reason for me being brought on is to try to save a project form failure and I basically just become another code monkey to take marching orders, then I don't want to do it. My manager found out what this team was using my time for and told them to fuck right off because he has a whole list of other projects where the team members will actually accept my help to keep the project from crashing and burning.

Decided to see for shits and giggles if I could make a cross compiler for the x86-64-pe target. As in Microsoft's Portable Executable format, but for standalone applications. Surprisingly, building binutils with this produces a valid toolchain. Building gcc with this will say it's an unsupported format. Decided to then try out my new assembler on a simple Hello World program, that I would test in Wine. It uses Linux system calls, which I know from experiments with MinGW in the past results in wine not bitching at all. The test program was this:

.section .rodata
str:
        .ascii "Hello World!\n"

.section .text
.global _start

_start:
        MOV 1,    %EAX
        MOV 1,    %EDI
        MOV str,  %RSI
        MOV 13,   %EDX
        SYSCALL
        MOV 60,   %EAX
        XOR %EDI, %EDI
        SYSCALL
        RET

The resulting program did not at all resemble an image in the Portable Executable format. Indeed, wine didn't know what the fuck it was, and the Linux "file" program seems to think it's just data. I can't really find out what the magic number means, although I have a hunch that this thing is just not applying the PE header or some shit. Pic related is what the outputted program looks like.

What do you think about testing if an array matches a hardcoded series of values by just chaining tests together in an if statement?

The emitted code -seems- like it would be extremely fast. It's just a series of instructions to compare values in a register followed by a jump if not equal. It would all likely come in on one cache line, all the instructions would be in the cache, etc. This seems like an ideal case, but is there anything better?

eg

if (id[0] == 255 && id[1] == 216 && id[6] == 74 && id[7] == 70 && id[8] == 73 && id[9] == 70 && id[10] == 0)

>>56418068
>In any other language you couldn't do that much complexity in one line

That's a good thing!

In most languages you can still put a bunch of arithmetic operations onto one line without it getting too long, and when this happens it becomes much harder to tell what that line is doing.

In Haskell, almost every line can be like this. Point-free style is the enabler, and it's notorious for making things hard to read.

https://wiki.haskell.org/Pointfree#Problems_with_pointfree

Ok /g/ i tried many languages out of curiosity. I'm not a professional but i'd like to make some programs. I'm mostly interested in desktop programs, and i'd like them to be cross-platform and to have a single code base, because i'm doing this in the little free time i have.
Since i'm a beginner i still make lots of errors, and a compiler is very helpful, as it finds out stupid erros before the program runs. So my choices are either java, c# or c++; with javafx, gtk# or qt. C# doesn't behave well on linux, c++ is quite hard to learn but qt is awesome, java is ok , my programs are mostly for personal use or for friends and i can just tell them to install the jre. So what should i learn? Java would be my first choice (because it also covers android apps), followed by c++, and then c#, because it doesn't work well outside of windows.

>>56418144
Why would it be better optimized?

(There's 5 if chains evaluating the same array, by the way.)

>>56418088

>>56418173
https://stackoverflow.com/questions/21106801/why-is-memcmp-so-much-faster-than-a-for-loop-check

Good compilers will pump out an SSE4.2+ intrinsic when they see a memcmp which is going to be an order of magnitude faster than a bunch of if statements.

You're literally just comparing whether one array (a block of memory) has all the same values as another array (another block of memory) which is the ideal case for memcmp.

Oh okay, he's just retarded.

Unless you're nesting them, ternaries are fine and people need to get a grip. They're perfectly easy to read in most every situation.

please help my retarded brain understand the point of dereferencing pointers

>>56418267
A pointer is an envelope with something inside, but you don't know what until you open it. Sometimes the envelope has a bomb in it and when you open it (dereference it) your program crashes.

You can't get at what's inside the envelope UNLESS you dereference though. If I give you an envelope and say "Hey, there's an integer in here!" and then ask you to add that integer to another integer, well, you can't do it without opening up the envelope and seeing what integer you have, right?

Why do people in these threads hate oop?

>>56418336
Op's a faggot

>>56418324

i see. So you should never print out a pointer without dereferencing it first, right? i guess the "tricky" part for me is when and when not to dereference

>>56418427
Dereference if you're going to use the data it points to, don't if you're going to use the address.

>>56418457
Also, printing out a pointer won't cause any kind of runtime error, it just won't print what you want it to.
