/dpt/ - Daily Programming Thread

What happened to the last thread?

Mods just nuked it?

Why?

Writing a rapidminer "clone" that actually uses fast libraries.

>>59275079
Yeah, I don't know why the got rid of the notepad one.
I'm pretty sure that one was valid.

>>59275095
It would be nice if the mods would make an appearance and explain. I didn't see anything out of the ordinary on that thread. No CP or anything.

So I'm trying to make a simple pattern generator in Ruby.

def carpetSquareGenerator()
    blockArray = ["▓", "▒", "░", "█", "▞", "▚"]
    carpetPattern = blockArray.sample(6).join
    carpetSquare = 3.times do print(carpetPattern,"\n") end
    return carpetSquare
end
print(carpetSquareGenerator)

This code outputs "3" after the pattern, like this:

▞█▚▒▓░
▞█▚▒▓░
▞█▚▒▓░
3

How can I prevent the "3" from being printed as well? Sorry for the noob question, I'm just starting out.

>>59275079
>>59275095
Probably because there were too many programming threads

>>59275145
The only other one is literally on page 9 and at bump-limit.

Reminder that if a new thread is created early but isn't deleted before the old one hits bump limit, it is now legitimate. If you create yet another new one after the bump limit, 9 times out of 10 it will be deleted in favour of the first new thread.

Attention, /dpt/:

The mods do not like C#.

There was entirely too much C# at the end of the last thread.

Please refrain from posting C#, or the threads will be deleted.

That is all.

Something probably easy but I can't figure it out.
Let's say I got a byte variable in Java.
I want to swap its 2 numbers places, so like 15 because 51, or 07 becomes 70. How can I do it without too much mess.

>>59275504

(n % 10 * 10) + (n / 10)

It only works if n < 100.

>>59275518
It is, since my byte value is always %100. Thanks

>>59275134

return carpetSquare

while i dont know ruby, that looks like you are returning 3 via that

>>59275504
You mean swapping the hex values? That's easy:

swapped = (a >>> 4) | ((a & 0xF) << 4);

If you want to swap the values in the decimal form, it's best to just convert it to a string and reverse the string.

>>59275568
>convert it to a string and reverse the string
That's the idiot's way of doing it.
If you ever bring a string operation into something not involving strings, you're doing it wrong.

So could someone redpill me on this notepad-chan nonsense? I haven't been here since last night because I've been busy studying

>>59275592
Swapping the places of two numbers does involve strings because the two numbers being swapped are from the string of the decimal representation of the number. The computer has no clue that it is decimal.

>>59275592
Oh please, if you're not using the built-in string operations then you're essentially just re-writing ParseInt or whatever the Java version is. And you're gaining absolutely nothing except a few bytes in memory.

If you're converting a number to a base that isn't a power of two you're creating a sub-class of the string. So why not just use the class that you already know works?

By that logic, C is bad because you can do stuff like

.

>>59276245
Undefined behaviour.

>>59276245
>>59276257

It's undefined by the C language. That case is very well defined by the implementation.

>>59275935
Can you point me to a webapp exemple or some source code so I can analyse and compile based upon that?

>>59275990
Very interesting...

>>59276294
You clearly don't understand the implications of undefined behaviour.

>>59276302
Oh yeah, the compiler might delete your stupid ass "undefined" statement because they love improving their little benchmarks.

>>59276242
Right click on the first one and click copy as curl. Now you can use this in your terminal to test it out. After you are able to replicate sending messages via curl, start removing arguments to curl you think are unnecessary. Some sites might check your headers when you try to post but a lot don't. After everything is stripped down you can convert your commands into the actual requests you need to do in your python script.

>>59276327
A compiler is under no obligations to do anything if your program has undefined behaviour, and is well within its "rights" to optimise based on the assumption that it never happens.
It's one of the reasons that C is inherently faster than most other languages.

>>59276362
>A compiler is under no obligations to do anything if your program has undefined behaviour,

Actually if there's undefined behavior, the entire program is undefined. So the compiler should just generate an empty executable and save us the trouble.

>It's one of the reasons that C is inherently faster than most other languages.

It's the reason compilers output absolute bullshit code sometimes. How in the fuck can you justify bugs that only happen at high optimization levels?

>>59276385
gcc used to have a feature that allowed you to throw c++ exceptions from trapping instructions like n/0.

>>59276339
okay thanks i copy and pasted everything you've said for me to do tomorrow as it is getting late here. I've apprciated your insight, i will probably come back tomorrow. Peace out

>>59276297
If you know what PRNG they use and if they use a cryptographically insecure algorithm (in which they want speed) you can possibly predict the next output of the generator.
It's also possible that the numbers are created from an algorithm and aren't random. In that case you'll need to reverse engineer it. Another Anon suggested to use machine learning. While that may work, you would need a lot more training data then what you showed in your picture.

>>59276385

When someone ships software in C/C++/Java do they compile the executable file with optimization flags?

>>59276586
Typically, yes.

>>59276586
No, it takes too much time to build and they include all debug flags so the user can see what happens when an assert goes wrong.

>>59276507
Yes, that's the Unix way. Error handling is code-word for bloat.

>>59276523
python 2.7+ compatible

print [(i,j) for i,j in enumerate([bin(x)[2:].zfill(8) for x in range(0,256)])]

>>59276586
Java doesn't optimize at compile time because it compiles to byte code and optimization depends on the native implementations (so optimization is done at run-time).

As for C/C++, usually people optimize to some extent for their release builds but there are some trade-offs especially for very large programs.

>>59276449
I do prefer error codes over the fucking brain damage that is C++ exceptions.

Exceptions are great for things like complex file reading and network stream reading where literally anything can go wrong at any given point for a dozen different reasons. The problem comes when people use exceptions as glorified goto statements and make no efforts to recover from recoverable errors.

>>59276777
That is what I end up doing most of the time. Sandboxes are glorious things, and you should set one up and just throw code or implementations at it until you get whatever it is sussed and fast.

Goddamn I love using Linux kernel system calls. They do it that way and they're so easy to use.

>>59276741
Or you can not be a fucking mathematician and write actual code that works.

>>59276723
It makes sense when your input can't be verified anyway. How do you verify your input pointer actually points to a null-terminated string? It requires traversal of the memory in question.

Honestly, I'd avoid designing brain-damaged data structures like that. Look at the mem* and str* functions; they're all equivalent if not for the fact that mem* takes pointers and sizes and str* takes null-terminated memory. Why the fuck do we need two sets of functions that do the same thing, but one is brain-damaged and fucks pajeets the world over every single day, while the other is sane?

Another interesting thing is about the "clever" Go implementation using segmented stacks. Your routines have stacks that are effectively unbounded, allowing really fast, effective and predictable stack memory allocation. Stack and static memory allocation is how you do real time code; you can't have motherfucking malloc fucking up your latency.

Unfortunately for Go, though, it was also designed with "lightweight threads" in mind. The idea is to enable you to write multithreaded web servers without all the asynchronous programming that comes along with the task. Hell, asynchronous programming is a thing because with a 1 thread/task model you exhaust your machine's memory since every thread normally allocates like 1MB of memory for its stack. Go allocates a lot less memory, allowing you to have millions of "goroutines".

These features smash right into each other. When a routine runs out of stack, which will happen often since they have small stacks, it allocates another stack and switches to it. This is no different than a malloc and may involve a system call. In practice this happens in the worst possible time, like tight loops, and you're basically fucked in that case. It will keep allocating and deallocating stacks right in the middle of the loop like a tard.

You'd think these people would invent a mechanism to do something like "hey a loop is about to start so let's preallocate a bigger-than-normal stack and switch to it in advance to guarantee performance" but no. They decided to get rid of the current implementation. Now when you run out of stack space, Go allocates a bigger one, copies the old shit to the new stack, and resumes from there. No different than a 4 year old's dynamic resizable array library. I've never seen developers backpedaling this hard

Really makes you think when you see Go diehards hyping their language like it's a "perfect C" or something. As if being designed by that Pike guy made it good. Sounds a lot like Apple when I think about it.

Why on earth would you sign that?

>>59277501
>>59277588

By embedded they mean "small computer" not "micro controller" or "low power optimized device" or "SDRAM driver"

You would use it if you want to avoid undefined behavior at all costs or if you really want a higher level language.

The reason why credit cards use a version of Java is because they don't want to leave anything to chance.

That sheet's probably for projects you don't want associated with the company. That's how it works at my company. Makes sense that proprietary software you write for the company belongs to them. If they're taking ownership of your side projects then you're probably signing onto a shit company.

anyone else find it easier to write code and then translate their thoughts to English later?

Yeah, it's more of that now that I've spent a little longer rereading it. The legalese is pretty dense. Probably going to hold off for a day on signing this to make sure I understand everything.

>I'm literally signing over the rights to everything I've ever made
i seriously doubt that. you may want to read it again. what they are probably doing (many companies do this) is informing you that they will own the rights to software you make while you are working for the company if it makes use of any company time or resources, and giving you a chance to declare any software you are already working on up front so that it's on paper that you were already working on it when you signed on with the company

>>59277694
Renegotiate your employment and tell them to remove the part that covers code written outside of company time.
That's a gross overstep of power and incredibly rife for abuse.

>>59277821

When you program C on a desktop computer, it's designed so that you can't access memory that isn't considered to be "yours."

This is because it has an OS and hardware memory protection.

When you program a computer without hardware memory protection, you can read/write any memory you want. Arrays are allowed to go out of bounds basically

>>59277792
take solace in the fact that if you were consistently confident in your ability as a programmer, it would almost certainly mean that you're a shit programmer. companies make use of shitloads of different technologies and internal codebases and they generally don't expect a new hire to already be extensively familiar with everything they might happen to use. they understand a good programmer will be able to ramp up in a reasonable amount of time. and if they expected people to at full productivity immediately, "ramping up" wouldn't be a term in the industry

Let us analyze what you're doing here...

carpetSquare = 3.times do print(carpetPattern,"\n") end

Print the pattern 3 times, and then set carpetSquare equal to the number of times you printed it.

return carpetSquare

Return the value of carpetSquare, which is 3, from the previous statement.

print(carpetSquareGenerator)

Call the function carpetSquareGenerator, print its return value, which is 3.

Remove the last print statement, remove the return value. Just make it like this:

def carpetSquareGenerator
  blockArray = ["▓", "▒", "░", "█", "▞", "▚"]
  carpetPattern = blockArray.sample(6).join
  3.times do
    print(carpetPattern,"\n")
  end
end

>>59278256
i won't claim a language should allow overloading as many operators as C++ does (i'll admit it's a bit ridiculous being able to overload the comma operator, among others), but i mean come on, not even basic arithmetic operators? there are tons of scenarios beyond primitive types where those are entirely predictable and well-defined

>>59278283
I'm disappointed in you doggo, pretty much any problem can be solved using heterogeneous lists

>>59278300
maybe, but not necessarily more effectively than with something else

>>59278292
Especially considering that those operators don't even do anything for classes, so it's not like you're overloading them so much as defining them.

That being said, the concept of interfaces are pretty much directly in line with the way Algebraic structures are defined mathematically. Too bad they're so ugly.

>>59278549

Nah, Karen's still insisting on Monads. I just realized I could achieve the benefits of everything he's talking about without actually giving a damn about type theory. I also realized it might make for an excellent PhD research. I've looked up "permissions based programming languages", and only seemed to find some that involve permissions on objects/state. I don't want to encapsulate state, but actions.

>>59277792
I know that feel. Computer Engineer here. A big company asked me to interview with them, and I got nervous and failed.

>>59278577

>>59278615

>encapsulate state
Mate, this is a procedural language. The basic unit of abstraction is the procedure, not the object. If you want to expand upon my work to make some sort of object-oriented message-based Frankenstein's monster of a language later down the road, be my guest.

>if I fail now maybe I'll add this to some sort of future PhD research though :°)
By the time you start your PhD, I'll have already finished mine, or abandoned this project.

Let me tell you first hand working in the real world that the nifty little single file programs are better written, more readable and more documented than 90% of the shit I deal with on a day to day basis.

When you code due to passion or interest, you bother giving a fuck. Once coding becomes your job, you do the bare minimum so you can't be fired. You will be amazed at how fucking fragile some programs are.

The C-subset of C++ has one big problem to me, it is its enforcement of strong typing, thus disallowing implicit conversion of void pointers. God, it is absolutely unnecessary to cast in this case, but you still have to use the long-ass static_cast otherwise, hence breaking compatibility with C.

>>59279820
>Implying I don't
If you ever worked in the real world, the deadlines are set in a matter they almost always require you to do overtime which I hate but I do anyway cause deadline. Bare minimum code is what 40 hours of effort is going to give you due to the way deadlines are structured. Are you sure you have worked in the fucking real world before or do deadlines not exist in your world place and you are free to spend weeks upon weeks on a single project?

Spoken like someone who has never worked in a real life job before. You don't directly produce a product, a team is behind it. You are assigned a component that is subjected to change at the whimps of your project leader, the design team, the sales team and whatever the fuck the client wants. While having to meet a deadline. Also real companies have dedicated departments designed to write test for products that don't remotely even touch products.

no? more like an array of 3-dimensional values. i've never seen a texture implementation where the channels weren't interleaved

>>59280426
In a large company there are specific departments that do specific stuff. The only time you juggle multiple roles in different projects is at small/medium startups. Or silicon valley lite companies that try to copy google. Even google has a very structured departmental setting, although you have a lot of freedom within the department itself. Anywhere else, you get assigned a department and a role. Say software engineer at R&D department. Or Unit testing. Or operations. Or backend etc etc. And after X amount of years, you can tell your department head/project leader you want a change in environment and then you can maybe transfer to another department. Software engineers are no different from any other engineers. An engineer working on cars motors is not going to be working on the electrical wiring of the car even if both of them are engineers working on developing a car (or any big software for that matter)

Those are important principles to know for the job interview. Past that stage, you can dump almost all the theoretical stuff out of the window unless you are in R&D or research.
